The PHP script s only change is the name of the targetFile which I have changed to ensure some sort of unique filename although not foolproof but otherwise the script is the same as released with comments removed here for brevity purposes . Can anybody tell my why Uploadify indicates that the file-upload was successful but no file-exists in the uploads directory I am using Windows PHP5.3 and the uploads folder is writable I can upload files there without Uploadify but not with it .. . .. . Thanks in advance Kobus .. . Answer : I had similar problems on a Linux machine . It turned out that the PHP configuration on my server was the cuplrit . PHP was running in SAFE MODE . As I had uploaded the Uploadify scripts via FTP so script files were stored in the file system with my FTP user details . Since PHP s temp folder was owned by the server root I had a UID mismatch i.e . the temporary upload file was attributed to root while the upload script that tried to move it was owned by the FTP user . That fragged it . To resolve this I changed the ownership of the uploadify php script to root and from there on it worked ." ] }	[ "yes-answer-long", "yes-answer-short" ]	website	UNK_RELATION

I m now writing a C-Application for an STM32 where I use this time FreeRTOS . It seems like FreeRTOS doesn t offer the same mechanism or did I miss something I think the five heap implementations are not what I am looking for . If there are actually no memory pools is there any specific reason why .. . Answer : The original version of FreeRTOS used memory pools . However it was found that users struggled to dimension the pools which led to a constant stream of support requests . Also as the original versions of FreeRTOS were intended for very RAM constrained systems it was found that the RAM wasted by the use of oversized pools was not acceptable . It was therefore decided to move memory allocation to the portable layer on the understanding that no one scheme is suitable for more than a subset of applications and allowing users to provide their own scheme . As you mention there are five example implementations provided http : www.freertos.org a00111.html which cover nearly all applications but if you absolutely must use a memory-pool implementation then you can easily add this by providing your own pvPortMalloc and vPortFree implementations memory pools being one of the easier ones to implement . Also note that in FreeRTOS V9 http : www.freertos.org FreeRTOS-V9.html you need not have any memory allocation scheme as everything can be statically allocated . Comment : One of the five example implementations of the heap may be suitable for allocating RAM for the OS tasks queues .. . what may also be the case for my application . But if I want to store some kind of messages basically a byte array which are all of the same size In this case I have to implement thread safe memory pools which I think is not very difficult as I cannot use pvPortMalloc or vPortFree as I use maybe heap 1", "Question : I would like to run the latest version of FreeRTOS on Teensy 3.2 using Atmel Studio Visual Micro .

I have settled on freeRTOS as the backbone for our OS and am working diligently to implement hardware functionality within the OS . However I have run into an issue concerning running 3rd-party applications from within freeRTOS . Originally I considered a task to be an application where basically you had myapplication.c and myapplication.h containing all your applications necessary functions and the code would reside within the for-loop within the task acting as a main while-loop . Then when the user decides to run that application a function pointer is passed to a queue that my app launcher task then uses to create the new task using the 3rd-party task or application . The problem with this approach however is the OS will already be compiled and reside on the microcontroller and applications with be installed and deleted as the user sees fit.. . So obviously applications need to be compiled and executable from the OS . On a standard unix machine I would use something like fork to select the executable and give it it s own process . However I cannot find a similar functionality within freeRTOS. . My other idea is approaching a scripting-language for app development but again I m not sure on how to launch those applications.. . So the question is how do I get freeRTOS to run applications from 3rd party developers that aren t already baked into the OS Comment : How is this related to Lua Comment : I should have fully explained that . Lua is one of the scripting languages I am looking at to address this problem . Thank you for bringing my lack of explanation to my attention . .. . Answer : FreeRTOS and most RTOSes for that matter do not work like general purpose operating systems GPOS they are not generally designed to dynamically load and execute arbitrary user supplied applications . In most case you use an RTOS because you require hard real-time response and the execution of third-party code could compromise that . Most RTOSes FreeRTOS included are no more that static-link libraries where your entire embedded application is statically linked with the RTOS and executes as a single multi-threaded program . Again many RTOSes like FreeRTOS are not operating systems in the same sense as a GPOS such as Linux . Typically the RTOS services available are the real-time scheduler inter-process communication IPC thread-synchronisation and timers . Middle-ware such as a file system and network stack for example are either optional extensions or must be integrated from third-party code . One problem you will have with FreeRTOS trying to achieve your aim is that a task is analogous to a thread rather than a process in the sense of a GPOS process model . A task typically operates in the same memory space as other tasks with no memory protection between tasks . Tasks are not separate programs but threads within a single application . If your target has no MMU then memory protection may be limited in any case but you may still want third-party applications to be conceptually independent from the OS . If your processor does not have an MMU then running arbitrary third-party dynamically loaded code may be a problem for system integrity safety and security . Even with an MMU a simple RTOS kernel such as FreeRTOS won t use it . Operating systems with real-time scheduling that can load and run application code dynamically as separate processes include : .. . .. . Windows Embedded Compact formerly Windows CE http : en.wikipedia.org wiki Windows CE .. . QNX Neutrino http : www.qnx.co.uk products neutrino-rtos neutrino-rtos.html .. . OS-9 http : www.microware.com .. . .. . Also VxWorks http : www.windriver.com products vxworks has the ability to load partially linked object code and dynamically link it to the already loaded code . This is not the same at a process model but is more akin to a dynamic-link library . What makes it worth mentioning in this context is that the VxWorks shell can invoke any function with external linkage by name . So you can load an object file implementing a function and then run that function . You could in principle implement the same functionality on FreeRTOS but it is non trivial . The shell is one thing but dynamic loading and linking requires the application symbol-table to be target resident . If you don t need hard real-time or your real-time requirements are soft and your target has sufficient resources you may be better served deploying Linux http : en.wikipedia.org wiki Linux on embedded systems or uClinux http : www.uclinux.org which are increasingly used in embedded systems . If the code your end-users need to run are tightly related to the purpose of your device rather than general purpose in nature then another possibility for allowing end-users to run code is to integrate a scripting-language interpreter such as Lua http : www.lua.org about.html . In this case you would simply load the script from a file system and pass it to the script interpreter . For more general purpose requirements a Java VM http : stackoverflow.com questions 10856437 embedded-java-vm-for-cortex-m3 10860479 10860479 may be a possibility . Comment : I am currently developing this on an ARM Cortex M4 so there is no MMU . We had to choose this processor due to the device needing to be as energy efficient as possible while still remaining responsive . Thank you for the links to OS alternatives I ll look into those now . Comment : We are looking for open-source or free for commercial use options . Excluding those from your list that leaves me with the linux options which also don t appear to be an option due to a lack of RAM. . I m looking into it more but it seems that I am stuck with an OS like freeRTOS to accomplish our needs . Comment : I ll give you the answer however I found an alternative solution using newlib . Thanks for the help Comment : @DevenJ : It is entirely legitimate to post an answer to your own question - you should perhaps do that because I am intrigued Newlib is merely a portable implementation of the standard-library so I am unclear how it has helped you solve this problem .

Answer : That is a massively open question that can only possibly be answered by asking many questions back to you so I will instead just offer advise . First I would suggest cutting the problem down into manageable pieces . Start by ensuring you can execute FreeRTOS on your part there are lots of Cortex-M examples http : www.freertos.org RTOS ports.html and even TCP examples for Cortex-M http : www.freertos.org FreeRTOS-Plus FreeRTOS Plus TCP TCP FAT demo projects.html and an FAQ to look through if you have problems getting the RTOS running all available on the FreeRTOS.org web site . Second in a bare metal application without an RTOS or OS check the lwIP driver is able to send and receive on the Ethernet port . Third add the known working Ethernet driver into your known working FreeRTOS project and check the Ethernet driver is still working taking note of the FAQ items on the FreeRTOS website with regards to having stack-overflow checking on configASSERT defined etc . . Fourth stitch in the lwIP code noting the lwIP recommendations for using the stack in a multi-threaded application . Fifth etc . etc .", "Question : null .. .

I see that GEM5 can run Linux and Android but I cannot figure out what modifications will I need so that I can run FreeRTOS on it . Are there any changes I need to do to the FreeRTOS code Or is it just a matter of writing a GEM5 config file Any help is appreciated .

Tracealyzer Recorder Library is v2.7.7 . Error is : .. . .. . Any hints on that matter would be helpful tnx in advance . .. . Answer : This is a basic tools question not a FreeRTOS or FreeRTOS+Trace question although you can fix it by changing the FreeRTOS configuration and or FreeRTOS+Trace configuration . The error is telling you that you have tried to use more RAM than the part you are using actually has or at least the amount of RAM you have told the linker your part actually has . If you look at the map file for your application you will see which variables are consuming RAM . Probably the single largest will be the FreeRTOS heap . The FreeRTOS documentation http : www.freertos.org a00111.html tells you how to reduce that . Probably the second largest will be the trace buffer and the trace configuration header file contains lots of documentation that will tell you how to reduce that .", "Question : null .. .

Although a lot of the code included in this example has now been superseded the integration with lwIP should still be valid and make a reference for you . If you are using one of the processors listed on the FreeRTOS+TCP examples page http : www.freertos.org FreeRTOS-Plus FreeRTOS Plus TCP TCP FAT demo projects.html FreeRTOS+TCP being FreeRTOS s own TCP IP stack then that may provide a further reference .", "Question : my goal is to run FreeRTOS from this site https : github.com jameswalmsley RaspberryPi-FreeRTOS.git on a Raspberry Pi .

Answer : To get started take help from existing operating-system recommended for raspberry-pi like : raspbian . Where all the necessary things bootloader for booting a kernel is there . So install raspbian first then from SD card you ll find raspbian s own kernel.img rename it take backup and then copy the freertos s kernel.img into SD card then try booting .

Comment : it looks like you have 2 versions of port.c :", "Question : I am looking for a small libc for embedded use with freertos on a ARM7 microcontroller . I have looked at newlib but it is a bit too complex for my needs . Newlib calls malloc in a number of functions e.g . printf which is not good for small embedded realtime systems . Does anyone know of a small portable open-source libc implementation that will fit my application Comment : What OS kernel are you using That s key to determining what your choices are . Comment : I m using freertos - freertos.org http : www.freertos.org .. . Answer : printf is not good for small embedded realtime systems Actually it is worse than malloc in many ways . Variable argument lists very complex formatting float number support when you don t need it etc etc . printf comes with an enormous overhead and the compiler will not be able to reduce it as every parameter passed to it is evaluated in runtime . printf is perhaps ok for hobbyists and beginners still learning C . But if you are a professional programmer you really ought to write your own serial monitor LCD routines . You will dramatically improve the program performance and flash consumption . Comment : Though technically not an answer I liked it . Comment : There is nothing wrong with using printf in embedded systems . There s something wrong with printf implementations that call malloc and do all sorts of useless things . A simple printf implementation without floating-point or that ignores exactness issues when printing floating-point and without POSIX i18n n argument specifiers can be implemented in about 2k of code and allows the calling application to be much smaller and simpler than if it had to duplicate printf -like functionality all over the place . Comment : There is nothing wrong with printf.. . -- ...can be implemented in about 2k of code . You obviously haven t worked with small microcontroller applications . 2k is huge . And if you can t even write a simple RS-232 serial monitor by yourself to replace printf you shouldn t be programming embedded systems in the first place . Comment : @Lundin : As Chris said there s a big range of embedded systems and often conditions like realtime bounded-time operations and failure-case-free are more important than extremely small memory size . I d be a lot happier with an embedded device that uses 1 MB of memory but always works because I know where allocations take place than a device that normally uses 128 kB and has 256 kB of physical memory but no strict bounds on usage and fails to do its job when an allocation fails . Comment : @R You want realtime and safety and therefore use stdio.h You are joking right", "Question : I m working with FreeRTOS on an STM32 Cortex-M3 and using the CMSIS library from ST to bootstrap everything . The CMSIS library defines the weak-symbol SVC Handler in the startup .s file . It must be overridden somewhere in order to get your ISR in the interrupt vector table . FreeRTOS defines vPortSVCHandler which is the ISR I want to have handle the SVC interrupt . I would like to glue the two together using my application code i.e . w o modifyng FreeRTOS or the CMSIS source code . I thought an alias would be the right tool for the job so I tried this in a separate source file main.c : .. . .. . That results in : error : SVC Handler aliased to undefined symbol vPortSVCHandler .. . .. . Turns out according to GCC documentation here http : gcc.gnu.org onlinedocs gcc Function-Attributes.html in order to use the alias attribute you cannot alias a symbol outside of the translation-unit . So I thought I d try to extern the symbol into main.c like so : .. . .. . This generates the same error . Any suggestions I would really like to avoid modifying either of the libraries . I know I could write a function SVC Handler that simply calls vPortSVCHandler but that could add unnecessary overhead to the ISR possibly depending on optimization settings . Note : The FreeRTOS examples accomplish this via a custom startup file . I m looking for a way to do this from C or my linker script . Compiler Version : gcc version 4.5.2 Sourcery G++ Lite 2011.03-42 .. . Target : arm-none-eabi .. . Answer : I m pretty sure SVC handler is only used by FreeRTOS at initial startup so adding an indirection exception handler isn t going to hurt performance but its ugly . Best ask this on the FreeRTOS forum response there is usually great . Hope this helps Best Regards Dave Comment : I should add that I need to do this w the SysTick and PendSV handler as well . I might ask on FreeRTOS forums too but it s really more a question about the GCC toolchain than about FreeRTOS ." ] }	[ "yes-answer-long", "yes-answer-short" ]	real-time	UNK_RELATION

If it can not be done I d also be interested in solutions using Boost Graph Library http : www.boost.org doc libs 1 59 0 libs graph doc index.html . The background is that I want to define smaller structural units as graphs annotate them with properties and add multiple copies of them together to create more complex structures . In the example below I have 3 graphs g1 g2 . and g3 consisting of a single vertex . I want to combine them into a single graph and be able to add edges to connect the vertices inside the resulting graph . However I don t know how to specify the copyGraph function correctly so that all vertices of g1 g2 and g3 end up in the same graph at the end . Also if g1 etc . contained multiple connected vertices these edges should remain intact . The example also contains a fourth graph gTest which looks like the result I want to achieve . However gTest here is created from scratch and not by combining the previously exisiting graphs .

What I am looking for is a way to create the result by combining g1 g2 and g3 . The part that only exists as pseudo-code . I m fairly certain it can be done using some form of copy-operation but I can t figure out how to do it correctly", "Question : Data structures for directed and undirected graphs are of fundamental importance . Well-known and widely-used implementations such as the Boost Graph Library http : www.boost.org doc libs 1 56 0 libs graph doc table of contents.html and Lemon http : lemon.cs.elte.hu trac lemon are designed such that the contiguous integer indices of nodes and edges are not exposed to the user via the interface . Instead the user identifies nodes and edges by small representative objects . One advantage is that these objects are updated automatically when the indices of nodes and edges change due to the removal of edges or nodes from the graph . In my opinion this advantage is overrated . Users will typically store the representative objects of nodes and or edges in a container e.g . an std : : vector . Now if nodes or edges are removed from the graph and their representative objects become invalid the user needs to either ignore this or rearrange the vector so as to keep valid integer indices contiguous i.e . do exactly the bookkeeping that the design was supposed to make unnecessary . Hence my question is : Does the design choice of hiding the contiguous integer indices of nodes and edges from the user have other advantages Comment : Interesting question but this may only apply to boost-graph using vecS . Boost allows graphs to be created using a variety of different containers . Not all of them requiring contiguous int indexes . The cases you mention adding and removing nodes or edges are poorly suited to the vector container . Comment : I understand that the Boost Graph Library allows us to store adjacency lists in containers that do not offer constant-time random-access but constant-time insertion and deletion of elements . This in turn allows us to insert and delete edges in logarithmic time in the degree of the graph provided that the containers are kept sorted . Constraining ourselves to containers with constant-time random-access renders the time-complexity for the insertion and deletion of edges linear in the degree of the graph . However in practice the absolute runtime can be kept small by using e.g . memmove . .. . Answer : I m at home in the Java world but hope that it is OK to give an answer that is not focussed on the particular libraries in question .. . .. . There are several possible advantages of such an abstraction . One of the most important ones was already mentioned in the question : The consistency when performing modifications in a graph is much harder to accomplish when indices have to be maintained . The reason why this may be hard lies in the different possible graph representations : It may be easy to maintain consistent indices if the internal representation only and always consisted of random-access lists of Vertex and Edge objects . But for other representations determining an index may be difficult . This directly related to the second main advantage : One is free to use different implementations of the graph interface . The section Graph Data Structures in the Review of Elementary Graph Theory http : www.boost.org doc libs 1 36 0 libs graph doc graph-theory review.html of the boost documentation lists several data-structures that are already offered by the BGL and everybody may add his own implementation . The running times for certain operations are given in Big-O-notation and once can see that they vary greatly between the different data-structures . So one can easily imagine that different implementations are better suited for certain tasks . For example consider an algorithm frequently has to check whether a particular vertex is contained in a graph . For an indexed that is list -based vertex storage this would require O n for each test . With a set -based storage of the vertices this could be done in O 1 - but there simply are no sensible indices in this case . Additionally as mentioned in the Graph Concepts http : www.boost.org doc libs 1 56 0 libs graph doc graph concepts.html overview : .. . .. . In fact the BGL interface need not even be implemented using a data-structure as for some problems it is easier or more efficient to define a graph implicitly based on some functions . So suggesting that there is an indexed access even when the graph does not even exist in memory may hinder such a purely-functional implementation .", "Question : I am looking at Lemon to handle my pathfinding since it has search and shortest paths algorithms among other things . The thing is I am already stuck right at the start in understanding how Lemon works and they have a tutorial but no forum to ask . My understanding of a directed-graph is that you have a node and it can link or not link-to another node and then you have a weight on it . Example : .. . .. . In this A is connected to B with a weight of 1 C is connected to nothing so once you get to C you are stuck and B connects to A with a value of 1 and B connects to C with a value of 5 . The tutorial says to do something like this : .. . .. . So now I have a graph g with the three nodes . Now what Where how do I add the connectivity information as well as the weight values .. . Answer : LEMON uses slightly different terminology than most graph-theory texts but in my opinion that makes using the library a bit easier . Firstly the difference between an edge and an arc in LEMON is simply that an edge is an undirected edge between two nodes and an arc is a directed edge . .. . .. . As for adding edges and weights and whatnot graphs themselves only manage nodes and edges arcs the only data associated with each is an integral identifier . You can find this identifier using : .. . .. . To attach pieces of data to the nodes edges you use maps . There are a few different types of maps but they generally boil down to a NodeMap EdgeMap or ArcMap - and as you probably guessed they are associative maps of Node V Edge V and Arc V respectively where V is the value-type which can be anything that has a default constructor . .. . .. . To add edges in an undirected graph or arcs in a digraph you simply create the two nodes and then use .addEdge n1 n2 or .addArc n1 n2 . For example : .. . .. .

However in practice the absolute runtime can be kept small by using e.g . memmove . .. . Answer : I can t speak for Lemon graph but for boost-graph I think the main goal is to be generic . So abstracting away the vertex edge access helps to achieve that goal . It is stated in the documentation that boost-graph is based on Dietmar K hl s Masters Thesis on generic graph algorithms . See my answer to Do property maps remain necessary for BGL http : stackoverflow.com questions 23540786 do-property-maps-remain-necessary-for-bgl 23677823 23677823 . So the main goal behind the library is to be generic and extensible . The choice of encapsulating access is part of abstracting the algorithms from the graph representation . To me continuous integer indices are an implementation detail . Boost doesn t make any assumptions on how you will use the graph or what performance trade offs are important to you . It lets you choose or implement the container that will best fit your needs . If you want to break this encapsulation you are free to do so . In fact my most common use of boost-graph involves vecS containers and a vector of struct s . I usually work with graphs where the size is fixed . I could just as easily use a map of vertex descriptor s or edge descriptor s to objects to achieve the same goal . So in summary I would say that this not so much a design choice but rather a consequence of achieving the broader goal of being generic . So the hiding of access has the benefit of being more generic .", "Question : null .. . Answer : Basically consider that we have two graphs to be merged .

It seems that lemon did not offer the possibility to support additional information to the edges within the graph . Therefore I just created a additional vector for storing this information .

This example before running the function with a specific graph implementation compiles normally . However when I un-comment exportToDot g I get the following compilation error : .. . .. .

Did I forget to clang a flag Does lemon is fully compatible with clang How to solve this error Comment : which lemon release development version did you use Comment : Edited lemon 1.3.1 Comment : Thanks that error can be effortlessly reproduced with clang++-3.5 which widens the audience a little . It s about the old problem of trying to assign ReverseIterators To ForwardIterators the forward it block just above in lemon path.h compiles without warning .

The lemon-developers must decide whether this is desired behavior a bug report should be filed for this . Comment : Wow thanks for taking that time . Links were useful to understand the mechanisms in-place . But I don t understand why gcc and msvc are ok with that but not clang . Does a workaround exist without modifying the library I am not a maintainer of lemon Comment : Yw . I m not connected to lemon either I use boost : : graph almost exclusively . In fact I leaned about lemon s mere existence from your post . About the whys and what-abouts - I suggest you formulate another question with a minimal core language no lemon or any external libs example that reproduces that difference between those compiler s behavior and tag that with c++11 g++ clang++ conversion-operator and language-lawyer . I haven t found any duplicate amazingly enough although I would not rule out that one exists but this may be important for the g++ or clang++ teams .

Answer : The method extractByNedTypeName needs the fully qualified NED type name i.e . including the package . In INET the StandardHost is usually in package inet.node.inet therefore you should write : .. . .. . EDIT .. . The loop for ListDigraph : : NodeIt n g n INVALID ++n is never executed because graph g has been just created and it is empty . The outer loop should be something like : .. . for int j 0 j numOutLinks j++ . EDIT2 .. . Because of lack of find for NodeMap one has to write own function for example : .. . .. . An example of using it : Comment : Oh yes you are right Comment : But at the same time I want the links to be extracted as well . I tried out the code by parsing through node list and checking for its remote node if any and adding it to the Lemon Graph using g.addarc u v but still its ineffective . Some hints would be good . Comment : Could you explain what do you mean writing ineffective Are there compile-time or run-time errors Does extractByNedTypeName method recognize all nodes you expected Which type of network do you use - wired or wireless Comment : Yes I think it is the best way .

Does someone have some recommendations for me Thank you a lot Bests M .. . Answer : As OWL files are RDF any RDF triplestore will do for storing them - though not every triple store will support OWL reasoning but then again you might not even need that . Some popular open-source choices for RDF storage querying are OpenRDF Sesame Apache Jena OpenLink Virtuoso Redland 4store and dotNetRdf . It s probably worth pointing out that several of these e.g . Sesame Jena dotNetRdf are storage-neutral APIs which means that several other open-source commercial triplestores can be accessed via them . So which triplestore API you pick depends on your requirements in terms of things like ease of use scalability reasoning support required and just generally which one you think looks cool . Have a look at this page http : answers.semanticweb.com questions 397 what-are-specific-triplestore-strengths-and-weaknesses for an overview of some of the strengths and weaknesses of the various offerings . Comment : I d also add that you have the option of using a dedicated OWL reasoner such as Pellet or HermiT . These won t provide persistent-storage and won t scale to the same level a database will but they ll probably give you the best performance for reasoning and are your only options if you need DL reasoning .

Answer : I see that SPARQL and RDF are all about standards which is cool . But what types of use cases would lead one to choose a triplestore over a property graph Comment : what s a property graph as in Property Graph Model https : github.com tinkerpop blueprints wiki Property-Graph-Model Based on the definition at the end of that document I d say that they re about the same except that if your edges end up having lots of properties you ve essentially got reified triples or n-ary relations . Comment : yes thats exactly what I meant . fyi people sometimes refer to a database that is implementing the property graph model as a property graph which is different than a triplestore containing RDF triples because in a triple store essentially all verbs are edges whereas the property graph has the distinction between attributes that identify an entity properties and attributes that identify a relationship between entities an edge . property graph enthusiasts tout its strengths in network-analysis and all of the popular algorithms that go along with it . Comment : Interesting question but it seems to me that this is rather too broad not to mention likely to attract subjective opinionated answers for StackOverflow . Comment : fwiw property graphs are easily represented in RDF so you can use a triple store as the backend and use either model you want", "Question : null .. . Answer : With a relational-database I can roughly visualise in my mind how the data on tables would be stored referenced and updated . However when I try to imagine this going on in a triplestore database I can t figure out how this would be happening without ending up with very fragmented storage of the data . Considering the below conceptual triples : .. . .. . .. . Elephant is a pachyderm .. . Eagle is a bird .. . Monkey is a mammel .. . .. . .. . ...and the following conceptual inferences : .. . .. . .. . pachyderm is a animal .. . bird is a animal .. . mammel is a animal .. . .. . .. . From what I can guess in order to identify each of Elephant Eagle and Monkey as animal s then we have to run the triplestore through a Reasoner https : en.wikipedia.org wiki Semantic reasoner . The way I m imagining it is as a cross between defragmenting a hard drive and performing a join in SQL to give : .. . .. . .. . Elephant is a pachyderm .. . Elephant is a animal .. . Eagle is a bird .. . Eagle is a animal .. . Monkey is a mammel .. . Monkey is a animal .. . .. . .. . If it s something along these lines then is a triplestore effectively some sort of massive normalised three field table that gets written out in full by the reasoner Comment : This is probably too broad for Stack Overflow . The short answer is yes a triple store s data is a massive three field table . Triple stores are typically going to efficiently index that in various ways to make query efficient . Reasoners might be built-in to a triple store or compatible with it but conceptually it s a distinct and optional thing . A triple store just needs to store triples . Comment : Oh isn t that an oversimplification . Granted some triplestores use a relational model under the hood but aren t there any that actually use a graph model Or something in between Comment : @TomaszPluskiewicz But conceptually what s the difference A graph of labelled edges is isomorphic to a set of triples source label destination . So yes a triple store is also a graph . But as far as the user is concerned the implementation doesn t really matter a triple store just has to be able to store triples . Comment : It s also important to note there s no reason that a reasoner needs to save the inferences ie materialize them they can all be computed on the fly at query time .", "Question : I m currently planning a big project containing big data .

So is it possible to create one for triplestore database Comment : FWIW we are currently investigating the possibility of a Sesame implementation for Hibernate OGM . Early days though . .. . Answer : You might try using Empire https : github.com mhgrove Empire which is an implementation of JPA for RDF SPARQL as opposed to RDBMS SQL . Empire is API agnostic so you can easily use any Sesame or Jena API compatible database with it which requires only changes to configuration . It should be pretty straightforward to implement support for other providers . It doesn t cover all of JPA there s some mismatch between parts which is currently omitted but the basics are covered . There are a few RDF specific annotations you d need to include to make an existing Hibernate implementation work but it should be an easy transition .

Comment : My use-case is quite simple : import RDF store in a triple store setup a SPARQL end point . .. . Answer : I can t give you a full list of features for either tool but I reckon that an important difference for your use-case given what little you ve told us is that wile 4Store is an RDF database implementation or triplestore Sesame is a framework API for handling RDF in Java giving access to multiple triplestore implementations including some of its own but also many third-party products . The possible advantage of this is that it allows you switching to a different database if you so require without major changes to your code . I would also imagine that Sesame s API being developed in and for Java is slightly more feature-rich and easy to use in a Java EE environment but this is merely an assumption as I am not sufficiently familiar with 4Store to make an actual comparison . disclosure : I am on the Sesame development team Comment : Thanks I see the main difference between the two system and can guess that for a simple use-case there isn t big differences .", "Question : Can somebody please describe the steps neccessary to convert a SQLite Database to a triple store Is there a tool that can accomplish the task .. .

That code explicitly checks all nodes starting from a certain node for a prefix match - it actually compares bytes . Can anyone point me to a detailed description on implementing a prefix search on radix trees Is the algorithm used in the Java implementation the only way to do it .. . Answer : Think about what your trie encodes . At each node you have the path that lead you to that node so in your example you start at that s a capital Lambda this greek font kind of sucks the root node corresponding to an empty string . has children for each letter used so in your data set you have one branch for i . .. . i .. . .. . At the i node there are two children one for m and one for n . The next letter is n so you take that .. . .. . i n .. . .. . and since the only word that starts i n in your data set is in there are no children from n . That s a match . Now let s say the data set instead of having in had infindibulum . What SF I m referencing is left as an exercise . You d still get to the n node the same way but then if the next letter you get is q you know the word doesn t appear in your data set at all because there s no q branch . At that point you say okay no match . Maybe you then start adding the word maybe not depending on the application . But if the next letter is f you can keep going . You can short circuit that with a little craft though : once you reach a node that represents a unique path you can hang the whole string off that node . When you get to that node you know that the rest of the string must be findibulum so you ve used the prefix to match the whole string and return it . How your you use that in a lot of non-UNIX command interpreters like the old VAX DCL you could use any unique prefix of a command . So the equivalent of ls 1 was DIRECTORY but no other command started with DIR so you could type DIR and that was as good as doing the whole word . If you couldn t remember the correct command you could type just D and hit I think ESC the DCL CLI would return you all the commands that started with D which it could search extremely fast . Comment : It s quite possible that my understanding of patricia tries is flawed but I believe that such tries store - in contrast to normal tries - complete words and always have two child nodes . In my example I have a root node which has a self reference and illness as a child . illness in turn has in as a child and also a self reference . imaginary is a child of in and has a reference to illness as well as to imitation .

Answer : My question is whether Trie data structure and Radix Trie are the same thing In short no . The category Radix Trie describes a particular kind of Trie but that doesn t mean that all tries are radix tries . If they are n t same then what is the meaning of Radix trie aka Patricia Trie I assume you meant to write aren t in your question hence my correction . Similarly PATRICIA denotes a specific type of radix trie but not all radix tries are PATRICIA tries . .. . .. . What is a trie Trie describes a tree data structure suitable for use as an associative-array where branches or edges correspond to parts of a key . The definition of parts is rather wide here because different implementations of tries use different bit-lengths to correspond to edges . For example a binary trie has two edges per node that correspond to a 0 or a 1 while a 16-way trie has sixteen edges per node that correspond to four bits or a hexidecimal digit : 0x0 through to 0xf . This diagram retrieved from Wikipedia seems to depict a trie with at least the keys A to tea ted ten and inn inserted : .. . .. . Basic trie http : i.stack.imgur.com EmJmU.png .. . .. . If this trie were to store items for the keys t te i or in there would need to be extra information present at each node to distinguish between nullary nodes and nodes with actual values . .. . .. . What is a radix trie Radix trie seems to describe a form of trie that condenses common prefix parts as Ivaylo Strandjev described in his answer . Consider that a 256-way trie which indexes the keys smile smiled smiles and smiling using the following static assignments : .. . .. . Each subscript accesses an internal node . That means to retrieve smile item you must access seven nodes . Eight node accesses correspond to smiled item and smiles item and nine to smiling item . For these four items there are fourteen nodes in total . They all have the first four bytes corresponding to the first four nodes in common however . By condensing those four bytes to create a root that corresponds to s m i l four node accesses have been optimised away . That means less memory and less node accesses which is a very good indication . The optimisation can be applied recursively to reduce the need to access unnecessary suffix bytes . Eventually you get to a point where you re only comparing differences between the search key and indexed keys at locations indexed by the trie . This is a radix trie . To retrieve items each node needs a position . With a search key of smiles and a root.position of 4 we access root smiles 4 which happens to be root e . We store this in a variable called current . current.position is 5 which is the location of the difference between smiled and smiles so the next access will be root smiles 5 . This brings us to smiles item and the end of our string . Our search has terminated and the item has been retrieved with just three node accesses instead of eight . .. . .. . What is a PATRICIA trie A PATRICIA trie is a variant of radix tries for which there should only ever be n nodes used to contain n items . In our crudely demonstrated radix trie pseudocode above there are five nodes in total : root root e which is a nullary node it contains no actual value root e d root e s and root i . In a PATRICIA trie there should only be four . Let s take a look at how these prefixes might differ by looking at them in binary since PATRICIA is a binary algorithm . Let us consider that the nodes are added in the order they are presented above . smile item is the root of this tree . The difference bolded to make it slightly easier to spot is in the last byte of smile at bit 36 . Up until this point all of our nodes have the same prefix . smiled node belongs at smile node 0 . The difference between smiled and smiles occurs at bit 43 where smiles has a 1 bit so smiled node 1 is smiles node . Rather than using NULL as branches and or extra internal information to denote when a search terminates the branches link back up the tree somewhere so a search terminates when the offset to test reduces rather than increasing . Here s a simple diagram of such a tree though PATRICIA really is more of a cyclic graph than a tree as you ll see which was included in Sedgewick s book mentioned below : .. . .. . Simple PATRICIA diagram http : i.stack.imgur.com fO57k.gif .. . .. . A more complex PATRICIA algorithm involving keys of variant length is possible though some of the technical properties of PATRICIA are lost in the process namely that any node contains a common prefix with the node prior to it : .. . .. . Complex PATRICIA diagram http : i.stack.imgur.com EH2AS.png .. . .. . By branching like this there are a number of benefits : Every node contains a value . That includes the root . As a result the length and complexity of the code becomes a lot shorter and probably a bit faster in reality . At least one branch and at most k branches where k is the number of bits in the search key are followed to locate an item . The nodes are tiny because they store only two branches each which makes them fairly suitable for cache locality optimisation . These properties make PATRICIA my favourite algorithm so far.. . I m going to cut this description short here in order to reduce the severity of my impending arthritis but if you want to know more about PATRICIA you can consult books such as The Art of Computer Programming Volume 3 by Donald Knuth or any of the Algorithms in your-favourite-language parts 1-4 by Sedgewick .", "Question : I m currently implementing a radix tree patricia-trie whatever you want to call it . I want to use it for prefix searches in a dictionary on a severely underpowered piece of hardware . It s supposed to work more or less like auto-completion i . e . showing a list of words that the typed prefix matches .

Can anyone point me to a detailed description on implementing a prefix search on radix trees Is the algorithm used in the Java implementation the only way to do it .. . Answer : An alternative algorithm : Keep It Simple Stupid Just make a sorted list of your keywords . When you have a prefix binary-search to find where that prefix would be located in the list . All of your possible completions will be found starting at that index ready to be accessed in-place . This algorithm will will require only 5 of the code of a Patricia trie and will be easy to maintain understand and update . It is almost certain this simple list search will be more efficient as well . The only downside is if you have huge numbers of long keywords with similar prefixes a trie can save some storage since it doesn t need to keep the full prefix for every entry . In practice if you have less than a few million words this is not a savings because the pointer overhead of the tree will dominate . This savings is more for applications like searching databases of DNA strings with millions of characters not text keywords .

The same API on a sorted array was much faster than a trie in JavaScript and I d expect the same to hold true for Python . .. . Answer : Someone else asked a question about Patricia tries a while ago and I thought about making a Python implementation then but this time I decided to actually give it a shot Yes this is way overboard but it seemed like a nice little project . What I have made is perhaps not a pure Patricia trie implementation but I like my way better . Other Patricia tries in other languages use just a list for the children and check each child to see there is a match but I thought this was rather inefficient so I use dictionaries . Here is basically how I ve set it up : .. . .. . I ll start at the root node . The root is just a dictionary . The dictionary has keys that are all single characters the first letters of words leading to branches . The values corresponding with each key are lists where the first item is a string which gives the rest of the string that matches with this branch of the trie and the second item is a dictionary leading to further branches from this node . This dictionary also has single character keys that correspond with the first letter of the rest of the word and the process continues down the trie . Another thing I should mention is that if a given node has branches but also is a word in the trie itself then that is denoted by having a key in the dictionary that leads to a node with the list . Here s a small example that shows how words are stored the root node is the variable d : .. . .. . Notice that in the last case a key was added to the dictionary to denote that abc is a word in a addition to abcdef and abcabc . Source Code .. . .. . You may have noticed that at the end I set getitem to the isWord method . This means that .. . .. . will return whether abc in the trie or not . I think that maybe I should make a module out of this and submit it to PyPI but it needs more testing and at least a removeWord method . If you find any bugs let me know but it seems to be working pretty well . Also if you see any big improvements in efficiency I would also like to hear about them . I ve considered doing something about having empty dictionaries at the bottom of each branch but I m leaving it for now . These empty dictionaries may be replaced with data linked to the word to expand the uses of the implementation for instance . Anyway if you don t like the way I implemented it at least maybe this will give you some ideas about how you would like to implement your own version .

Can anyone help me with the algorithm for prefix searches in the above case Should I consider these as keys of separate length i.e 24 and 16 .. . Answer : If you use this trie for storing IP numbers as elements of the fixed length then it is definitely not the right way . The point here is that PT is especially useful for storing variable-length data . If you store parts of IP numbers as prefixes of variable-length then PT is a good choice . In this case yes your keys should be of different length . Let s say you are storing prefix 192.168 in binary 0xC0 0xA8 you add this as first key . Then when searching for IP like 192.168.1.1 you can get information that your trie contains 192.168 which is a prefix of what you look for . All you have to do is to store the common part while traversing the trie . This is a minor addition to the this http : www.codeproject.com KB string PatriciaTrieTemplateClass.aspx implementation . Just make sure that while going down the trie you store the common part somewhere in the parameters of the recursive function . For good understanding of Patricia trie I would suggest reading Robert Sedgewick s Algorithms book http : www.cs.princeton.edu rs which is a great source of knowledge . EDIT : There is one problem when storing C strings in PT . This trie is designed to store binary-data but you are interested only in getting the whole bytes . Make sure you are storing common part of the prefix only if its size in bits is multiple of 8 . For a wrong example : you have key in your tree : 0xC0 0xA5 and you are looking fro 0xC0 0xA6 . Your traversal will stop when the common part 0xC0 0xA but you are interested in taking only 0xC0 . So make sure to store common bytes not bits .", "Question : I am implementing Patricia tries for IP prefix lookup I could get the code working for complete key match but facing problems with prefix search when there are keys which are prefixes of other keys like : .. . .. .

Comment : You could also add parts of the Address or the birth date to the key ideally something that helps the user to select the right entry . To make sure you have a unique key and you don t need a list as value also append a unique record id . You may want to hide the id from the user . Comment : @amit : To get a partial match in a tree start iterating over the keys at the prefix until you find an entry that does not match the prefix . Tries may have a better performance in theory but there is a reason why most standard libraries don t have them : Memory consumption is horrible and the data structure will be scattered over a huge memory area causing cpu-cache issues .

Comment : As far as I know you CAN T run SIM applets in Eclipse IDE without any simulator . You need to use a SIM card simulator or try to run it on a real SIM card . For uploading and installing your applets first of all you need to convert your applet to CAP file . You need to work with converter tool in Java Card development kit . instead of that you can simply use Eclipse-JCDE plugin to convert your applets . After converting you need to upload this CAP file on the SIM card . You can use some already-written open-source tools . GlobalPlatformPro is one of them . Google it Comment : Thank you for response I have a real SIM card and a reader i think i can load my applet into this sim card.. . But I think that I should add the JCOP plug-in to eclipse in order to get the .cap file . i cant find the package JCOP in internet i wonder if it is availble in free do you have an idea Comment : No you can t find a free version of it . But you can use Eclipse-JCDE plugin instead . download here : sourceforge.net projects eclipse-jcde files http : sourceforge.net projects eclipse-jcde files I don t have any idea that you can use it for convert applets that contain SIM APIs or not but I m sure that it is sufficient for converting Java Card applets to CAP files Comment : I added Eclipse JCDE plugin and it s work i can now create applet convert it to a .cap file and give it an AID ... . .. . Answer : You can t run SIM applets in Eclipse IDE without using a simulator and you need to use a SIM card simulator It can be a plugin for your IDE also or try to run your applet on a real SIM card . Moreover for uploading and installing your applets first of all you need to convert that program to a CAP file . There is a tool in Java Card development kit named converter that you can use it to convert applets to CAP files . Instead of using converter tool directly you can simply use Eclipse-JCDE http : sourceforge.net projects eclipse-jcde files plugin to work with this tool and convert your applets . After converting you need to upload this CAP file on the SIM card . You can use some already-written open-source tools to aim this goal . GlobalPlatformPro https : github.com martinpaljak GlobalPlatformPro is well-documented one . Note that : I m afraid if the Java Card Development kit is able to convert applets with proprietary SIM APIs to CAP files . but for applets that contains only Java Card API you can use it simply . Comment : Exactly i am having problems with my applet because of the SIM APIs any idea to resolve this problem Comment : @DGz Unfortunately no idea . where did you download the SIM APIs I think in some ETSI packages you can find useful tools . There was some question in this community useful for you . Look at SIM tagged questions Comment : Yes It is a ETSI package I downloaded the SIM API packages from this : stackoverflow.com questions 22362327 http : stackoverflow.com questions 22362327 sim-toolkit-application-javacard-development-kit 22471187 22471187 Comment : @DGz I left a comment there.I Hope David help us : Comment : Hello Abraham I did exactly what David said i extract the Annex B Export Files and copied the sim directory into the export files directory api export files everything work normaly now i can convert applets even with SIM API proprietary .

Answer : SmartCafe Expert 3.2 72k http : www.smartcardfocus.com shop ilp id 521 smartcafe-expert-3-2-72k p index.shtml is a simple regular Java Card and does not contain SIM Toolkit APIs inside . So it can t install those applets that used SIM Toolkit APIs . In the loading process the OPEN on the card is trying to make a link between your applet and the used libraries . As it can t find SIM Toolkit library there it returns this error . Comment : I had a sneaking suspicion as much . Time to go shopping again but I appreciate the answer . Do you have any words of wisdom on knowing which Java Cards will support STK APIs e.g . if it says Java card and SIM in the description http : www.smartcardfocus.com shop ilp id 776 smartcafe-expert-6-0-80k-sim p index.shtml is there a good chance it will support Java Card applets and STK APIs", "Question : I would like to programmatically access an STK SIM Application Toolkit application without using my handset .

Answer : Recently I m trying to work with SIM Application Toolkit . I want to get the menu list of the services given by the SIM . For doing that as far I know I have to activate the SIM toolkit functionality using AT+STSF 1 AT command which several GSM developer guides say . But While giving that command to set the functionality I m getting an ERROR result . Meanwhile I m using a modem which is STK supported . Whats the actual problem here or is there any other way to select the menu of those services provided by the SIM . I ve googled a lot about it but unfortunately not getting the real answer . Please help me in this regards . Thanks in advance . Comment : Have you entered ATI to check that you are on the right port you should see modem details Have you unlocked the SIM Can you send other AT commands What error-code are you seeing view the error-code by first entering AT+CMEE 1 and then re-trying AT+STSF 1 What happens if you try AT+STSF or AT+STSF Comment : Also see this question stackoverflow.com questions 536682 http : stackoverflow.com questions 536682 getting-started-with-stk-programming Comment : The modem is on the right port i m sure . The other basic AT command work fine such as sending sms . AT+CMEE 1 returns OK AT+STSF AT+STSF returns nothing but the AT+STSF 1 returns ERROR . Actually is there any other per-requisite to activate the STK functionality of the SIM card Comment : Does the 3rd answer in the question linked above help Comment : @HabiburRahman did you get to solve this problem I am also experiencing similar issues .", "Question : I want to communicate from my Android app to a Java Card applet loaded on a SIM card using APDUs under Android prior to 5.0 4.2.2 for example . My applet is not a SIM Toolkit applet it is a common Java Card applet . Following this post http : stackoverflow.com questions 30325663 send-apdu-commands-to-usim-sim-card-in-android thanks to @vojta and @jean and SEEK https : github.com seek-for-android pool wiki UsingSmartCardAPI I would like to build my app using RIL Radio Interface Layer . Where can I get those libs The only ones I can get is for Nexus - here https : developers.google.com android nexus drivers . If I understand it well I will have a different .apk file for each mobile manufacturer . Am I right If yes is there any other way to communicate from Android to SIM applet apart from SEEK If I cannot avoid that I really think SEEK is the best or the only way to communicate with my SIM applet can someone share a step-by-step manual for building such an example APK application including communication with the applet .. . Answer : You cannot simply add that functionality RIL extensions to access a UICC SIM-based secure element to an app . Instead the mobile phone has to support this functionality . You typically cannot replace the radio interface library telephony framework on the fly you could probably do such kind of patching on rooted devices but still that s not something you would typically integrate in your app . However many current Android devices come with a ready-made SEEK implementation that could be used to access the UICC SIM card many devices by Samsung e.g . GS3 and later Sony HTC and Motorola . When it comes to Nexus devices the Nexus 6 is the first that supports SEEK . On devices that support SEEK i.e . that come with the SEEK smartcard service preinstalled you can use SEEK by linking your application to the SEEK SDK-addon http : seek-for-android.googlecode.com svn-trunk repository 19 addon.xml or by integrating the Open Mobile API directly either as a library-project or by adding the source files into your application you can find the latest version here https : github.com seek-for-android platform packages apps SmartCardService tree android-5.0.0 r3-scapi openmobileapi src org simalliance openmobileapi . You can find a sample application for access to smartcard applications through SEEK here : https : github.com seek-for-android open-mobile-api-sample", "Question : I m trying to develop a STK application but I don t know where to get the development kit . Right now for Javacard I m getting the one from Oracle s website but it doesn t have the sim.toolkit package . I don t want to buy it from Gemalto etc . Is there any free implementation I have found the ETSI - 3GPP http : www.3gpp.org DynaReport 0319.htm a zip file with some code and libraries but I don t know if this would be enough . Do I generate the cap jar file from the code there Thanks .. . Answer : The files from 3GPP should be enough to complement the Javacard libraries that you ve downloaded from Oracle . Just as you need to know the Javacard version of your card you need to know also what version of SIM API the card support . Check it againsts the 3GPP TS 03.19 that you ve mentioned or you may also check for 3GPP TS 43.019 http : www.3gpp.org DynaReport 43019.htm . Download the correct version . Here is some steps I used to generate SIM API library : .. . .. . 1 . Download related SIM API archieve for example 3GPP 43.019 v5.6.0 http : www.3gpp.org ftp Specs archive 43 series 43.019 43019-560.zip .. . 2 . Extract the 43019-560.zip file .. . 3 . Extract Annex A java.zip under it .. . 4 . Open the extracted Annex A java directory .. . 5 . Zip the sim folder .. . 6 . Rename the sim.zip extension to sim v5.6.0.jar .. . .. . Besides the JAR file you also need to copy the export files required when generating CAP file . 1 . Extract Annex B Export Files.zip .. . 2 . Open Annex B Export Files directory .. . 3 . Copy the sim directory into your collection of export files directory . Hope it helps Comment : How we can convert SIM API contained packages to CAP files As far as I know JCDK Converter tool is able to convert pure Java Card APIs to CAP files only and it is not useful for SIM APIs right Comment : We don t need to convert API to CAP file . What we need to do is to convert class files to CAP file . JCDK is able to convert any APIs . Just make sure that you put the JAR and the EXPort files of the API . Comment : I must add the JAR files to my project . but what about the Exp files where I must put them I know that I must put the in the directory of other export files but where are those Comment : You can add it under java card kit-2 2 2 api export files along with com java javacard and javacardx directory .", "Question : I m testing a SIM Toolkit application using AT Commands . I have a USB modem that supports SIM Toolkit Class 2 features and is based on the Open AT Firmware . I am able to successfully interact with the SIM Toolkit by using the +STSF +STGI and +STGR commands . I also receive +STIN replies as per the message flow shown here http : www.scribd.com doc 61188000 196 Messages-Exchanged-During-a-SIM-Toolkit-Operation .

Based on the Terminal Profile the Call Control bit is set to 1 or enabled . You will also notice that the Autoresponse is set to 1 . Therefore I receive an +STGI response when a message is sent . Here is the lead up to when the SIM sends an SMS message : .. . .. . You can see that +STIN : 9 means an SMS message is sent out . I believe based on my initialization I should also see an +STCR and there should be some text in the +STGI . If anyone is familiar with the SIM Toolkit and accessing it through the AT Command set then I would appreciate some insight as to why I do not receive a response when an SMS message is sent out . Thanks . Reference : 1 : Wavecom AT Commands Interface Guide for X51a - WM ASW OAT UGD 00016 Comment : Whats your modem .. . Answer : I think the USB modem is busy for doing other task .

I am suppose to get a SMS once the item is selected but I get no response . What could be wrong . All I see is OK in the terminal .", "Question : While loading an applet to a sim-card i get Authentication failure error . Because of the limited try of sim-card key i wonder this error means the card is blocked or nor Comment : Depends what status word do you receive Comment : the word is just like authentication failure . What happens when the card is blocked Comment : The ISO 7816 status word SW is normally printed in binary two bytes e.g . 6982 . Comment : There are many reasons why a load application could fail . The status word will give you a hint maybe but these values depend on card manufacturers . Comment : @takumar they depend on card manufacturers unless they have been clearly defined by the standard that defines the APDU s such as Global Platform . ISO 7816-4 which defines most APDU s is however not much help I grant you that . Worst specification ever . .. . Answer : Before loading an applet you must to do an authentication with the Card Manager on Smartcard . In order to do the authentication you have to know the card issuer keys . There is a limit number of attempt to authenticate . Usually this number is 10 . If you exceed this limit the card will block . Once you do a successfully authentication this limit is reset . Comment : Actually i successfully load an applet to the same card before . When i want to load the other applet i get this error . is it necessary to configure the card again and i get this error more than 10 times . Is it possible to repair the card Comment : The amount of attempts is specific to the implementation . The problem with limiting the number of attempts is that it makes the card susceptible to denial-of-service attacks . Not blocking the card will however open the card up to side channel attacks brute forcing keys is normally not feasible . Normally when the card manager is blocked then the game is over unless the card has a proprietary unblocking mechanism implemented . Check the user-manual of the card you are trying to use ." ] }	[ "yes-answer-long", "yes-answer-short" ]	sim-toolkit	UNK_RELATION

What about more than two images If it was Wolfram Mathematica I would take a List of those images and transpose them to get a single image where each pixel would be an array of N pixels -- there I would apply a Mean function to them . But how do I do that with vips There are so many Vips : : Image http : www.rubydoc.info gems ruby-vips8 Vips Image methods and only here http : www.vips.ecs.soton.ac.uk supported current doc html libvips libvips-conversion.html vips-bandmean I could find some minimal description on what do they all mean . So for example : .. . .. . I wanted it to mean calculating an average image but I m not sure what I ve done here . Comment : Could you explain what you are trying to accomplish Are you trying to load a set of images and find the average value of each pixel Comment : @user894763 specifically yes . Imagine them as noisy photos of the same object and that I want to clean it . But in general I would like to know the way to apply any my custom function pixel1 pixel2 .. . pixelN . .. . Answer : ruby-vips8 comes with a complete set of operator overloads http : www.rubydoc.info gems ruby-vips8 0.1.0 Vips Image -instance method so you can just do arithmetic on images . It also does automatic common-subexpression elimination so you don t need to be too careful about ordering or grouping you can just write an equation and it should work well . In your example : .. . .. . +- with a constant always makes a float image so you might want to cast the result down to uchar before saving or maybe ushort or you ll have a HUGE output tiff . You could write : .. . .. . By default new from file opens images for random-access . If your sources images are JPG or PNG this will involve decompressing them entirely to memory or to a disk temp if they are very large before processing can start . In this case you only need to scan the input images from top to bottom as you write the result so you can stream the images through your system . Change the new from file to be : .. . .. . to hint that you will only be using the image pixels sequentially and you should see a nice drop in memory and CPU use . PNG is a horribly slow format I would use tiff if possible . You could experiment with bandrank http : www.vips.ecs.soton.ac.uk supported current doc html libvips libvips-conversion.html vips-bandrank This does something like a median filter over a set of images : you give it an array of images and at each pixel position it sorts the images by pixel value and selects the Nth one . It s a very effective way to remove transitory artifacts . You can use condition .ifthenelse http : www.rubydoc.info gems ruby-vips8 0.1.0 Vips Image ifthenelse-instance method then else to compute more complex functions . For example to set all pixels greater than their local average equal to the local average you could write : .. . .. . You might be curious how vips will execute the program above . The code : .. . .. . will construct a pipeline of image-processing operations : a series of vips add http : www.vips.ecs.soton.ac.uk supported current doc html libvips libvips-conversion.html vips-cast to sum the array then a vips linear http : www.vips.ecs.soton.ac.uk supported current doc html libvips libvips-conversion.html vips-cast to do the divide and finally a vips cast http : www.vips.ecs.soton.ac.uk supported current doc html libvips libvips-conversion.html vips-cast to knock it back to uchar . When you call write to file each core on your machine will be given a copy of the pipeline and they will queue up to process tiles from the source images as they arrive from the decompressor . Each time a line of output tiles is completed a background-thread will use the selected image write library libtiff in my example to send those scanlines back to disk . You should see low memory use and good CPU utilization . Comment : Your hints about existing +- operators are very useful thanks . But what if my function is not that simple as .reduce : + .size but has if-branches etc . Would it be enough easily implementable in Ruby or I d have to jump down to C Comment : You can use .ifthenelse to add branches and there are a whole series of operators to build various local filters . Most things should be easy maybe start another question if you get stuck . There s the vips tracker as well it s quite active : github.com jcupitt libvips issues https : github.com jcupitt libvips issues Comment : I added a silly ifthenelse example .", "Question : I ve been using Python 3 and Numpy to handle an image-processing task where I m assembling small tiles into a large complete image .

Where jj is an entry of the filelist that records where each tile beblongs . I m wondering if similar operation can be achieved in VIPS with Python .. . Answer : VIPS has no destructive operations : you can only build new images you can t modify existing images . This restriction is why vips can do things like automatic parallelisation and operation caching . Behind the scenes it has some extra machinery to make this less inefficient than it sounds . You can solve your problem like this : .. . .. .

Answer : You can t really do it in one step from the command-line with vips https : github.com jcupitt libvips issues 325 unfortunately . You need to use one of the bindings C C++ nip2 Ruby Python and join several operations together . I d suggest Python http : www.vips.ecs.soton.ac.uk supported current doc html libvips using-from-python.html . You could do : .. . .. . On this laptop Dell XPS-13 I see : .. . .. . That s joining 100 2500x2000 RGB tiffs side-by-side to make a HUGE strip . It runs in about 800MB of ram . I would use TIFF rather than PNG if you can . PNG is extremely slow .", "Question : I m trying to diagnose why my Python server app is leaking memory . The app takes a request for an image url resizes it using Vips and returns the image . After every request the memory usage grows roughly by the size of the original image . I ve tried using muppy the pympler tracker but each diff after the image open close operations showed only a couple of bytes being used . Could the external C libraries be the cause of the memory leak if so how does one debug that . If it s anything related I m running the python server inside a docker-container .. . Answer : I m the libvips maintainer . It sounds like the vips operation cache : vips keeps the last few operations in memory and reuses the results if it can . This can be a huge performance win in some cases . For a web service you re probably caching elsewhere so you won t want this or you won t want a large cache at least . You can control the cache size with vips cache set max and friends : .. . .. . http : www.vips.ecs.soton.ac.uk supported current doc html libvips VipsOperation.html vips-cache-set-max .. . .. . From Python it s : .. . .. . To turn off the cache completely . You can set the cache to limit by memory use file-descriptor use or number of operations . There are a couple of other useful things you can set to watch resource usage . Vips.leak set True makes vips report leaked objects on exit and also report peak pixel buffer memory use . Vips.cache set trace True makes it trace all operations as they are called and shows cache hits . In your code I would also enable sequential mode . Add access Vips.Access.SEQUENTIAL to your new from buffer . The default behaviour is to open images for full random-access since vips doesn t know what operations you ll end up running on the image . For things like JPG this means that vips will decode the image to a large uncompressed array on open . If the image is under 100mb it ll keep this array in memory . However for a simple resize you only need to access pixels top-to-bottom so you can hint sequential access on open . In this mode vips will only decompress a few scanlines at once from your input and won t ever keep the whole uncompressed image around . You should see a nice drop in memory use and latency . There are a lot of other things you could handle like exif autorotate colour management transparency jpeg shrink-on-load and many others I m sure you know . The sources to vipsthumbnail might be a useful reference : .. . .. . https : github.com jcupitt libvips blob master tools vipsthumbnail.c Comment : using Vips.leak set True vips only reports peak memory usage when the server is stopped this is also when the Python script exits . Should I be closing vips after processing a request Comment : I d leave vips running you ll save the startup shutdown time . The peak memory reporting is handy for testing not so useful in production . The C API has a thing to get current peak memory but it s not exposed to Python I ll add this . libvips has a fairly large test suite all written in Python and one of the tests is does the entire test suite complete with no memory-leaks so hopefully you shouldn t see leaks in your server and it s more of a double-check .", "Question : I m currently working on a project where I have an image of around 3.9gb .

Comment : how much memory do you have What windows is this x64 is the vips.exe 32bit some reasons : from win Vista and later the Process scheduler changes a lot and now older programs that does not response inside much smaller time limit will be freezed . you can try run the program in XP SP3 compatibility-mode wtih turned off advanced gfx stuff that sometime helps prevents the program has stop working message . If you got 32bit App then you are limited to 4 or 2 GB of memory depends on used memory manager of the app and allocation of chunks above 1GB can be problem sometimes . Comment : In that case try to find 64bit version of the App if you got 64 bit OS of coarse or cut the image to smaller pieces . As this is not a programing question I vote to close Comment : Thanks for your answer : . There seems to be only a 32-bit version of the program I have 32gb of memory though the reason I would like to not close this topic is because it s not solved . I posted my question here because LibVIPS is an opensource software package that seems to have problems reading my image . I don t really see a difference between including the library in my project or directly calling VIPS.exe . To make my question as simple and focussed as possible I chose to use their version of the compiled program instead of using their library in my own project . Comment : 1 . 32-bit programs runing on x64 windows are running inside WoW64 emulator and have access only up to 4 GB of memory does not matter if you have 8GB or 128GB installed . Some memory managers depends what with your program was compiled can use only 2GB address space . I also found out that sometimes under WoW64 if you want to allocate single block with more than 1 GB in size that sometimes crashes even if you got that much of memory from that 4GB . This site is for questions related to programing . I think you should post this in different Stack Exchange site not sure which may be super user Comment : But if LibVIPS is OpenSource than you could try to build it as 64bit app that is perfectly suitable for this site.. . just download the package source code repository tortoise is good for this then install some 64bit compiler compatible with this package I guess some MSVC++ or GCC and compile 64 bit binaries .. . I am afraid you will need some aditional stuff like frameworks SDK s as nowdays programmers are unable to do standalone stuff instead you need to include countless crappy libs to make helo world example .. . and need tons of crap installed to run exe .. . .. . Answer : I m the libvips maintainer . The vips.exe binary includes bigtiff support and should be easily able to process an image of this size . It s challenging to build yourself on Windows perhaps a week s work I wouldn t try to make your own unless you are very expert . I think the problem is probably your input image . I think it is using very large tiles 4096 x 4096 . libvips is having to keep two complete lines of tiles in memory so 4096 x 131072 x 3 x 2 pixels which is 3GB straight away . I would remake your source image . Use smaller tiles perhaps 512 x 512 and make sure you are writing a bigtiff image . Please open an issue on the libvips tracker if you still have problems it s easier to debug stuff there . https : github.com jcupitt libvips issues .. . .. .

I indeed already heard that compiling libvips on Windows was quite a challenge . I will try to decrease the tile size and recreate the image to see what happens then . Maybe a bit offtopic but what tiff version does libvips use Is that 4.0.6 from remotesensing.org libtiff http : www.remotesensing.org libtiff which follows the Tiff 6.0 spec or is it something completely different Comment : Hi again the windows vips is built by this : github.com jcupitt build-win32 https : github.com jcupitt build-win32 You can see the tiff library here : github.com jcupitt build-win32 blob master 8.1 https : github.com jcupitt build-win32 blob master 8.1 vips.modules L265 So it s libtiff 4.0.6 .", "Question : I want to use VIPS to append a directory of many smaller images in to one massive image .

Answer : This issue has been discussed on the vips issue tracker : .. . .. . https : github.com jcupitt libvips issues 393 .. . .. . But briefly : .. . .. . radius is the same as sigma in IM . vips picks a radius for you based on the sigma setting . x1 corresponds to threshold though the scaling is different . The vips one is calculated on a L difference image I guess the IM one is in the range 0 - 1 so probably multiply the IM value by 100 . y2 and y3 don t seem to have an IM equivalent . They are useful in printing to limit the amount of haloing you get on edges I don t know how useful they d be for screen output . The defaults are probably reasonable but you could try turning them down . m1 is I think always zero in IM you could try making this a small value it can make the transition from flat areas to edge areas less jarring . m2 is equivalent to amount I think though the scaling is probably different . There are some other differences . The vips one just operates on L of CIELAB that is it s just a sharpening of the lightness channel and it s perceptually uniform . The vips one was really designed for offset print work so it s currently hard to make the much gentler adjustments you need for screen . There are some patches going through now which should make vips sharpen more suitable for display output . Summary : there probably isn t a perfect parameter match up since the underlying operators are rather different .", "Question : I ve had following codes that use Python and OpenCV . Briefly I have a stack of image taken at different focal depth . The codes pick out pixels at every x y position that has the largest Laplacian of Guassian response among all focal depth z thus creating a focus-stacked image . Function get fmap creates a 2d array where each pixel will contains the number of the focal plane having the largest log response .

In a very simple test : .. . .. . I get correct result . In my full program the work for each thread involves read binary from a source file turn them into tiff format read the image data and insert into canvas .

The above module imported as mcv is called in the driver script : .. . .. . To examine the content I used Comment : I thought of another possible problem : vips uses a recursive algorithm to walk pipelines and work out which bit to calculate next . If your pipeline is extremely long and the C stack on your platform is rather small you can get a C stack-overflow . Could that be the problem I would edit your question to include a complete example program that fails plus a description of your platform and the vips version . You could also open an issue on the vips tracker it s a better place for debugging : github.com jcupitt libvips issues https : github.com jcupitt libvips issues Comment : Thanks for your comment I ll have to read on C stack-overflow . I m not quite sure what it means.. . I ve included complete program here . The file to be read from contains 5000 small tiles saved in .jxr format . .. . Answer : I think your problem has to do with the way vips calculates pixels . In systems like OpenCV you perform a series of operations on images . Each operation does a large number of calculations and modifies memory in some way . Vips is not like this though the interface looks similar . In vips when you perform an operation on an image you are actually just adding a new section to a pipeline . It s only when you finally connect the output to some sink a file on disk or a region of memory you want filled with image data or an area of the display that vips will actually do any calculations . vips uses a recursive algorithm to run a large set of workers up and down the whole length of the pipeline evaluating all of the operations you created at the same time . To make an analogy with programming-languages systems like OpenCV are imperative vips is functional . The good thing about the way vips does things is that it can see the whole pipeline at once and it can optimise away most of the memory use and make good use of your CPU . The bad thing is that long sequences of operations can need large amounts of memory to evaluate whereas with systems like OpenCV you are more likely to be bounded by image-size . In particular the recursive system used by vips to evaluate means that pipeline length is limited by the C stack about 2MB on many operating systems . Here s a simple test program that does more or less what you are doing : .. . .. . You run it like this : .. . .. . It loads k2.jpg a 2k x 2k JPG image repeats that image into a 2 x 2 grid and saves a small part of it . This program will work well with very large images try removing the crop and running as : .. . .. . and it ll copy the huge tiff image 100 times into a REALLY huge tiff file . It ll be quick and use little memory . However this program will become very unhappy with small images being copied many times . For example on this machine a Mac I can run : .. . .. . But this fails : .. . .. . With a 28 x 28 output that s 784 tiles . The way we ve built the image repeatedly inserting a single tile that s a pipeline 784 operations long -- long enough to cause a stack-overflow . On my Ubuntu laptop I can get pipelines up to about 1 400 operations long before it starts failing . There s a simple way to fix this program : build a wide rather than a deep pipeline . Instead of inserting a single image each time make a set of strips then join the strips . Now the pipeline depth will be proportional to the square-root of the number of tiles . For example : .. . .. . Now I can run : .. . .. . Which is 40 000 images joined together . Comment : Thanks for the response I figured I need to do the threading myself because these small images are actually in .jxr format . The work for each thread is : open a file read a chunk in binary save in .jxr call JxrDecApp to decode and save in .tiff call Vips to read into memory . I suppose this can t be handled by Vips itself Comment : Can you get the jxr decoder to write the uncompressed byte array to memory If you can you could skip the tiff save load and make a vips image directly . Comment : That s my next step . Now the openly available jxrlib only reads and writes files . I ll have to understand the jxr decoder and modify it so it can directly decode binary-data into memory . But even if I do so don t I have to handle the threading myself And still I m not sure what went wrong in my implementation I posted. . Comment : Your example should work and it sounds like it does but you re still threading something that doesn t need to be threaded . I would make your source tiffs in parallel but build the vips pipeline single-threaded . Also use bigtiff : canvas.write to file complete.tif bigtiff True .

OpenCV can provide more sophisticated ways to compare images stackoverflow.com questions 11541154 https : stackoverflow.com questions 11541154 checking-images-for-similarity-with-opencv .. . Answer : There must be hundreds of ways of measuring image similarity it s a huge field . They vary mostly in what features of an image they try to consider . A family of similarity measures are based on histograms as Scott said . These techniques don t consider how your pixels are arranged spatially so your two images could be considered the same if one has been rotated 45 degrees . They are also fast since finding a histogram is quick . A simple histogram matcher might be : find the histograms of the two input images normalise so the two hists have the same area .. . this removes differences in image-size subtract square and sum . Now a small number means a good match larger numbers mean increasingly poor matches . In ruby-vips8 this would be : .. . .. . On my desktop this runs in about 0.5s for a pair of 2k x 3k JPEG images . Many matchers are based on spatial distribution . A simple one is to divide the image into an 8x8 grid like a chess-board take the average pixel value in each square then set that square to 0 or 1 depending on whether the average of the square is above or below the average of the whole image . This gives something like a fingerprint for the image which you can store neatly in a 64-bit int . It s insensitive to things like noise scale changes or small rotations . To test two images for similarity XOR their fingerprints and count the number of set bits in the result . Again 0 would be a perfect match larger numbers would be less good . In ruby-vips8 you could code this as : .. . .. . Again this runs in about 0.5s for a 2k x 3k JPEG . Yet another family would be based on correlation see spcor http : www.vips.ecs.soton.ac.uk supported current doc html libvips libvips-convolution.html vips-spcor and friends . They might be more useful for finding a small area of an image . Many fancier image similarity metrics will take a variety of algorithms run them all and use a set of weighting factors to compute an overall similarity measure .

Answer : I have a few thoughts.. . .. . .. . Thought 1 .. . .. . If your input images are 15MB and for argument s sake your output images are 1MB you are already using 80MB s of disk bandwidth to process 5 images a second - which is already around 50 of what a sensible disk might sustain .

Mmm seems a good bit faster . YMMV of course . Thought 3 .. . .. . Depending on the result-of your test on disk speed if your disk is not the limiting factor consider using GNU Parallel to process more than one image at a time if you have a quad core CPU . It is pretty simple to use and I have always had excellent results with it . For example here I sequentially process 32 TIFF images created as above : .. . .. .

Comment : When I use python3 which should not work the error is : File usr local lib python3.5 site-packages gi init .py line 39 print url SyntaxError : Missing parentheses in call to print . So it s finding a gi in that directory but it only has init .py . When I say pip3 install --upgrade gi it says Requirement already up-to-date : gi in usr local lib python3.5 site-packages . Comment : And thank you again for helping me with this .", "Question : I have looked through some of the documentation available Here http : www.vips.ecs.soton.ac.uk supported current doc html libvips using-from-python.html for Vips but have not found an answer yet . I want to put the image into a numpy 3D array similar to how PIL images automatically get processed this way : .. . .. . . This is what I have for Vips so far.. . So I get that error at the end because I m not pulling the data in the right format from the Vips Image object . Comment : Check the type of the image with type image see if they are both the same . Post an update . Comment : I did and I got gi.overrides.Vips.Image so one is a PIL Image object the other is a Vips image object . Which is fine since I have read in the Vips documentation that the image is stored as a representation of width height bands channels . But I have not been able to find the function that allows me to retrieve the data and put it in an array . I also did this -- In 27 : Vips.Image.guess interpretation im2 Out 27 : enum VIPS INTERPRETATION sRGB of type VipsInterpretation -- So they are also both RGB mode . Comment : Thanks but this didn t seem to work . This was the result-of writing it out like that : In 7 : y x.cast Vips.BandFormat.FLOAT .write to memory In 8 : z Vips.Image.new from memory y x.width x.height x.bands Vips.BandFormat.FLOAT In 9 : arr numpy.asarray z dtype numpy.float32 arr numpy.asarray z dtype numpy.float32 File usr lib python2.7 dist-packages numpy core numeric.py line 460 in asarray return array a dtype copy False order order ValueError : setting an array element with a sequence . .. . Answer : Expanding on the answer from user894763 .. . .. . output : .. . .. . This was on a 2500x2500 8bit color .jpg image . Comment : Awesome man this worked Now I do have a question however you end up doing 3 arrays and 3 transforms I fear the speed boost gained with Vips will be lost if I have to do all this additional computation . Is there a way to get the D array in one line Comment : @alfredox check the edit to my answer . I used my previous code because I needed the intermediate arrays . Reshaping the 1d array directly to 3d is a bit faster . Comment : Awesome thanks man", "Question : I built VIPS 8.1.1 with .. . .. . I downloaded the package from the sourceforge project website http : sourceforge.net projects libjpeg-turbo files 1.4.2 . After installing the package I configure Vips with .. . .. . When I tried either loading jpeg file or saving jpeg file I had this error message : .. . .. . Did I build the VIPS the wrong way Should I build with other version of libjpeg-turbo Or is it other problem I found another library file named libjpeg.so.62 I tried uninstalling Vips and rebuild again with this file but the problem persists . .. . Answer : That message is produced by libjpeg if the headers don t match the library . It sounds like you ve built against .62 headers but tried to run with the .80 library binary . Check your system for old header-files and remove them . Maybe apt-get remove libjpeg-dev Comment : The folder I specified for jpeg-libcludes has only jpgelib.h for the libjpge-turbo-official I installed . Its location is different from any other jpge library existing on the computer . I can t remove those anyways because there are needed by some other program . Does Vips look for jpeglib.h in addition to the place I specified Comment : gcc will always search every directory on -I for jpeglib.h . Check the exact flags that are reaching the compiler to see which one it s picking up . You should be able to remove the -dev version of the package it s only got the headers in no program needs it at runtime . Comment : You don t say what platform you are using but you probably have a platform libjpeg-turbo . I would use that rather than building your own . It has the same ABI so it s simple drop-in replacement . Comment : I m using ubuntu 14.04 LTS . Indeed there is already a libjpeg-turbo on it . Where can I see the which jpeglib.h the compiler picked up Comment : Oh perfect . It s the same headers just remove the libjpeg-turbo you built don t give vips any flags and it ll pick up the turbo version automatically . Use ldd to verify which library it s linking to at runtime ." ] }	[ "yes-answer-long", "yes-answer-short" ]	image-processing	UNK_RELATION

From my reading it looks like JSData mainly deals with accessing data while Sequelize.js will create and modify the scema and ALSO provide access to the objects . Is there any point in using JSData on the server-side if I use Sequelize.js I am thinking to use Sequelize on the server-side implement some REST API to those objects and use JSData + JSDATA-http on the client-side to access the REST API but it feels that I will have to define the objects twice.. . once for Sequelize and once for JSData - is there any magic that can prevent the need to do this twice or am I thinking about all this in the wrong way .. . Answer : Does JSData replace or complement Sequelize.js I am trying to understand how those two libraries can play together and if they should . On the server js-data + js-data-sql would replace Sequelize similar to how js-data + js-data-mongodb would replace Mongoose . js-data-sql uses Knex.js under the hood which you can use for schema migrations and for anything else that Knex supports . For schema validation you can plug your favorite validation library into js-data via the validate lifecycle hook and other places . Is there any point in using JSData on the server-side if I use Sequelize.js No .. . .. . I am thinking to use Sequelize on the server-side implement some REST API to those objects and use JSData + JSDATA-http on the client-side to access the REST API but it feels that I will have to define the objects twice...once for Sequelize and once for JSData - is there any magic that can prevent the need to do this twice I actually have experience using js-data + js-data-http on the client and Sequelize on the server . You could do that but yes you have have to define each of your Models Resources twice once using the Sequelize API and once using the js-data API . You can mitigate duplication by extracting common logic into base models than can be used by the server and the client . Though if you use js-data on the server you can compose complex queries right in the client without having to translate them to something the server s ORM understands . or am I thinking about all this in the wrong way No you re just trying to understand your options . Being the author of js-data I would of course argue in favor of js-data + js-data-sql but the major areas where js-data + js-data-sql lags behind Sequelize is that Sequelize has native support for belongsToMany n : m relationships and a built-in understanding of sql datatypes validation is up to you with js-data . Comment : Thanks For your response and thanks for writing this tool . I would like to point that going through the documentation it did not pop out that js-data actually manages stuff like creating tables and so on . Could you point me towards an example showing how this works and when in the codes life cycle does it happen also if you could elaborate on the sql datatypes issue it could be helpful . As for n : m one can probably use n : 1 + 1 : m relations to overcome this... . Comment : js-data does not automatically create tables . Creating tables only even makes sense when you re using the sql adapter . Mongo automatically creates collections for you and the other adapters have no notion of tables . Example of creating tables with the sql adapter : github.com js-data js-data-examples blob master server sql app https : github.com js-data js-data-examples blob master server sql app app.js L197 It happens only where you make it happen . n : 1 + 1 : m is how n : m works it s just Sequelize understands this and hides the intermediate table . With js-data you d have to deal with the intermediate table .

Answer : I am new to Node.js and Sequelize I have mostly a C background EF WebApi etc and I am trying to setup a simple Node.js project with sequelize . I checked the https : github.com sequelize express-example which seems very nice and simple but I can not understand how this whole system handles the lifetime of the objects created . They seem to use a singleton reference for the ORM using requires . If that is the case what happens when one request creates updates a few entities in sequelize and for whatever reason they are not saved Should they be visible on the next request How can I prevent that so that in each request sequelize entity state is clear from previous requests I though about recreating the instance but it seems that this is an anti-pattern in the node.js world . They also say that you need one instance so that the same DB connection is reused instead of opening a new connection each time but I am not sure that this is the case . Can someone clarify how to handle the ORM reference please and the implications on the entities already loaded on the server I also plan to use breeze js with sequelize http : breeze.github.io doc-node-sequelize class-descriptions.html .

These interests are linked to the user via a lookup table . In PHP I queried the users table then for each one did a query to find interests . How can I do this in Node.js Sequelize How can I set up some sort of promises too For example : .. . .. . .. . Answer : From the return statement in the bottom of your code it seems you have not totally grasped the asynchronous nature of node.js . The return statement in your code will be executed directly after the first call to sequelize.query that is before the query returns . This means that users will be undefined . If you wanted to actually return the users and their interest I would suggest something like this : .. . .. . In the code above refers to a utility lib . that executes the callback function after the function has been called users.length times . Callback is a function that is passed to your piece of code and should process the return result for example returning the users to the client in the context of a webserver . Another comment - if you are only doing raw SQL queries Sequelize might not be the best choice for you . Any reason why you are not using the SQL driver directly If you want to use sequelize you should take advantage of its features . Try to the define a model for users and interests set up an association and load up users and interests in one go using JOINs eager-loading http : sequelizejs.com documentation models-eager-loading .. . .. . update : An example using promises Comment : Just remember that you have to include underscore https : npmjs.org package underscore module Comment : is already used in sequelize and exposed via Sequelize.Utils . Comment : Hi Jan I was blocked on the same issue for many hours . I tried using Promise.all without any luck . I m new to node.js and all the async stuff so likely I ve been confused but I was wondering if you had a working example using Promise.all thanks In any case your answer works and helped me a lot .

That modal is used in different places but unfortunately it was pretty hard to share the controllers so I wanted to make sure that all of the controllers implemented the methods and properties that the modal requires hence the interface . Comment : Oh and specifying properties on interfaces works the same as methods -- you just don t add @param or @return annotations - .", "Question : null .. .

Answer : font-lock-mode colorful syntax highligthing . global-font-lock-mode enables font-locking for each and every mode in Emacs . Older Emacs version required you to enable it manually newer version 23+ I think enable this by default . I can t imagine that many people would want to turn off this feature since it makes some type of content like source code immensely more readable .

Here s the blog post http : nex-3.com posts 79-highlighting-ruby-in-haml-mode with a high-level description . Note that the current haml-mode has some problems with Emacs 24 compatibility but a couple of forks have fixes for this . Regarding multiline font-locking I think you may be asking the wrong question . But basically this solves the problem of what to do if the user has made an edit in the middle or the end of a multiline syntactic construct . Initially font-lock starts refontifying the buffer from the position of the point . The two default font-lock-extend-region-functions font-lock-extend-region-wholelines and font-lock-extend-region-multiline move the start of the refontification region to the beginning of the line and then maybe somewhere even further depending on the font-lock-multiline property . If you need it to move further up you either add another function to font-lock-region-functions or make sure to backtrack programmatically while parsing certain constructs inside font-lock-region-function or syntax-propertize-function . One example of the latter approach would be Ruby s heredoc and ruby-syntax-propertize-heredoc in the Emacs trunk . It is called from two places in ruby-syntax-propertize-function . The first time to handle the case-when we already are inside of a heredoc literal and then for any subsequent heredocs .", "Question : Some background I m comfortable with Emacs Lisp and have written lots of lines of it .

The only requirement is that I m able to see the chunks by applying a different face to them . .. . Answer : In the example below I use the anchored form of font-lock keywords it allows you to search more than the current line . The trick is that the pre hook do two things : 1 it allows you to position the point to the start of the search and 2 it allows you to limit the search by returning the end-position . In the example below I have used the second property . Note that this is only a proof-of-concept . You will need to make sure that the font-lock-multiline variable and the font-lock keywords are applied to the correct buffer . Below the first two lines of BAR will be highlighted but not the last : Comment : In this thread http : lists.gnu.org archive html help-gnu-emacs 2004-09 msg00534.html Stefan Monnier says that font-lock-multi-line is appropriate for things that are usually single-line but occasionally multi-line . Comments Comment : Well Stefan Monnier is the definitive reference when it comes to anything font-lock related so any advice from him is well-worth following . Using the syntactic system as he suggests is one way to do it . Another is to use a match function rather than a regexp which could match the entire block . You should see my answers as a direct answer to the question provide an example of the multi-line font-lock feature and maybe not an answer on best way to accomplish whatever the original poster asked about .", "Question : I m trying to write a derived mode from fundamental-mode .

Also you have wisely changed the rule to use myregex only once which will speed up the code by about 3 . But you need to wrap the keywords into one more pair of parentheses .

Can someone show me a clear example of how this is can be done EDIT : I should clarify that I don t want to see mode-specific font-locking within the javascript css chunks . The only requirement is that I m able to see the chunks by applying a different face to them . .. . Answer : I ll outline a simple major mode for highlighting style CSS and script JavaScript etc . blocks . To get multiline font-lock working reasonably well you ll need to first enable it by setting font-lock-multiline to t and write a function to add to font-lock-extend-region-functions which will extend the relevant search region to contain larger blocks of text . Then you ll need to write multiline matchers either regular expressions or functions and add them to font-lock-defaults . Here s a basic major mode definition that names the font-lock keywords list here test-font-lock-keywords enables multiline font-lock and adds the region extension-function test-font-lock-extend-region . The region extension-function should look something like this : .. . .. . This function looks at the global-variables font-lock-beg and font-lock-end which contain the starting and ending positions of the search region and extends the region to contain an entire block of text separated by blank lines or n n . Now that Emacs will be searching for matches in larger regions we need to set up the test-font-lock-keywords list . There are two reasonably good ways to go about matching multiline constructs : a regular expression which will match across lines and a matching function . I ll give examples of both . This keyword list contains a regular expression for matching style blocks and a function for matching script blocks : .. . .. . The first item in the list is straightforward : a regular expression and a face for highlighting matches of that regular expression . The second looks a bit more complicated but can be generalized to specify different faces for different groups defined in the match data specified by the function . Here we just highlight group zero the entire match using font-lock-keyword-face . The relevant documentation for these matchers is in the Search-based fontification http : www.gnu.org software emacs manual html node elisp Search 002dbased-Fontification.html section of the Emacs manual . A basic regular expression for matching style blocks would be : .. . .. . Note that we have to put n in the inner group because . does not match newlines . The matching function on the other hand needs to look for the first script block in the region from the point to the single given argument last : .. . .. . This function sets the match data which is a list of the form begin-0 end-0 begin-1 end-1 .. . giving the beginning and end of the zeroth group first group and so on . Here we only give bounds on the entire block that was matched but you could do something more sophisticated such as setting different faces for the tags and the contents . If you combine all of this code into a single file and run M-x test-mode it should work for highlighting these two types of blocks . While I believe this does the job if there is a more efficient or proper way of going about it I d also be curious to know as well .", "Question : How do you change the default face which Emacs uses to style text on a per-mode basis For example say that I am already happy with the face customizations that I have which include a default fixed-width font . However in one particular mode markdown-mode.el say I want the default font to be variable-width . It is easy to style headers links etc . uniquely for markdown-mode : simply place the cursor over the styled text and M-x describe-face then click the link-to customize it . However the default face is the face used if no other face is specified so it is not specific to markdown-mode and if modified will affect all other modes . What magic can I put in the markdown-mode-hook to set the default face for buffers using this mode Comment : If there is a some variable that controls the default faces then you can localized it for the current buffer only in a hook that getting called while opening a file w markdown . Comment : The question is asked in a general way then a specific example is made and answers revolve around this specific example . If you really need to Set Emacs defaut font-face per-mode see Using a different font for each major mode - Emacs Stack Exchange http : emacs.stackexchange.com questions 3038 using-a-different-font-for-each-major-mode 3042 3042 .. . Answer : I have to give a partial answer because this is too complicated to figure out on the spot and I already blew my time budget . Face is a frame property . A frame can display multiple buffers at the same time . Mode is a buffer property . You ask how to vary the face on a per-mode basis . Combining all this it seems that the question cannot not have a single fully-correct answer . You can approximate the desired answer if you assume that a given frame will never display more than one buffer . You can actually accomplish that with something like this but modified to use special-display-regexps and a set of regexps that match your markdown-mode buffer names . However this is probably not what you want . Your question seems to imply changing the face properties of a single frame . Again assuming that a frame will never display more than one buffer at a time you can try advising switch-to-buffer . But that might not be sufficiently low-level and it might be too slow . untested .. . .. . And now for my actual incomplete answer.. . .. . .. . A better albeit more complicated approach would instruct markdown-mode to use a new face for all regions that are not already assigned one of the built-in faces . You can create a new face with copy-face and give it interesting properties with set-face- . Modify markdown-mode s font-lock-defaults to override the default font-lock-fontify-region-function as described in the comment block near line 946 of font-lock.el that begins Fontification functions . You can probably use a very slightly modified font-lock-default-fontify-region that does just one extra step immediately after it does : .. . .. . The extra step parses the region similar to what font-lock-fontify-syntactically-region does breaking the region into interesting sub-regions . But this time you find sub-regions that have the default face and you put-text-property those sub-regions to the new face that you previously created . In all this feels like it should be only a couple lines of elisp in your .emacs file plus make a copy of font-lock-default-fontify-region that has only a minor diff from the original call one new function plus make a copy of font-lock-fontify-syntactically-region and modify it to do your bidding the most difficult part . Actually if you after advise font-lock-fontify-syntactically-region then you probably don t even need to modify font-lock-defaults or font-lock-default-fontify-region .

The regular expression expression matches the typical PHP tags and their enclosed text . However if there are any string-literals in the body of the PHP block then the highlighting fails .

Comment : I didn t really try to change the regexp --- I was assuming that it was correct and the problem was that two font-lock rules applied to the same text and @JonClaus needed to have this rule override the other .

If you have a backslash there then you intend not to match a backslash either . Dunno whether that is what is wanted here . Comment : So font-lock-keyword-face must also be matching className .

Comment : You re confusing two things here . The third argument to font-lock-add-keywords controls how these keywords are added to the existing ones . By using a non-nil and not set the keywords are appended to the existing set i.e . the opposite of prepend .

In Eclipse this is done with Ctrl+T but pressing Ctrl+T on the method did nothing in Netbeans 6.5 and I can t where the type hierarchy functionality is in Netbeans 6.5 . Thanks . .. . Answer : To get a hierarchy similar to the type hierarchy in Eclipse right-click on the class name select Navigate and then Inspect Hierarchy . The keyboard shortcut for this is ALT+SHIFT+F12 . By default it shows you parents of the selected class or interface . However you can view descendants by using the Filters at the bottom left side . I believe the Show Subtype Hierarchy filter also toggled by using CTRL+B is what you want . This is accurate in NetBeans 6.7.1 . I m going to assume it is similar in 6.5 .

Eclipse shows me the various implementations ALT+SHIFT+F12 doesn t do anything for an interface in Netbeasn 6.5.1 .", "Question : For some reason my lib as JSTL 1.1 in the libraries list is empty.. . The jars paths were removed from the classpath with Tools - Libraries dialog.. . How can I restore the JSTL jars back for NetBeans6.5.1 So my question is what jars JSTL 1.1 lib should contain and where to look them for in NetBeans installed folders .. . Answer : On my system JSTL 1.1 library contains the jars : .. . .. . As to where they are located they re buried in Netbeans . Specifically on my machine a Mac there is a .netbeans folder in my home folder . Pretty sure this exists on Windows as well . Within .netbeans there s a folder for your specific version 6.5 in this case . Within that is a modules directory . The jars are located at : .. . .. . The association of the jars to the library are made in a file : .. . .. . If these files are all intact you might want to try and remove the folder : .. . .. .

Comment : I have found this jar as org-netbeans-modules-web-jstl11.jar in C : .. . NetBeans 6.5.1 enterprise5 modules folder . Should I add this jar to lib classpath or I should add as you say those two .netbeans 6.5 modules ext jstl.jar .netbeans 6.5 modules ext standard.jar Comment : You re probably best off simply creating a new library for your project then add those two jars and make sure you click the option to copy the jars to your local library directory . Then they ll always be with the project . Comment : The thing is I have library JSTL 1.1 in the NB6.5.1 Class Libraries libraries list but it is empty . All jars by mark JSTL 1.1 were removed that s why I just want to re-add the jars paths as it used to be before their paths were removed . but I am not sure should I add the org-netbeans-modules-web-jstl11.jar or the two you mentioned as .netbeans 6.5 modules ext jstl.jar .netbeans 6.5 modules ext standard.jar Please give me a little more details at the point . Comment : I m saying fixing this is not something I think you can do easily save for re-installing Netbeans . Instead since you have the jars on your system create a NEW library for your project add those two jars to it and make sure you copy the jars in to your project and then simply remove the Netbeans JSTL 1.1 lib from your project .

Thanks to tkellerer for pointing this out on the Netbeans forums .. . .. . http : forums.netbeans.org viewtopic.php p 49638 49638 .. . .. . This is widely overlooked functionality in Netbeans perhaps because there is no key binding for it so I ve changed my enhancement request to add a key binding for the sequence Alt+F7 check Find All Subtypes and click OK Comment : I know this is an old post but I have never found that Netbeans find implementations works reliably and I wonder whether it has to do with the context the function is used in . For example do projects in which implement the interface need to be open I work with a lot of OSGi bundles and very rarely does this function work in Netbeans and it s something that would be extremely useful in that context .", "Question : I am working with the NetBeans 6.5 IDE .

You can change the L F with setLookAndFeel even after the program s GUI is visible .

Comment : @a horse with no name : As is this question . I asked it over three years ago . .. . Answer : It is because of constant class loading . Java stores class byte code and all the constants e.g . string constants in permanent heap that is not garbage collected by default which make sense in majority of situations because classes are loaded only once during the lifetime of an application . In applications that often load classes during an entire lifetime that are : .. . .. . web and application servers during hot redeployment .. . IDE s when running developed applications every time you hit Run button in Netbeans or eclipse it loads your application s classes a new .. . etc this behavior is improper because a heap fills full eventually .

I use options .. . .. . stopped my eclipse-3.4 from throwing java.lang.OutOfMemoryError : PermGen space so it should also work with netbeans . Edit : Just note that for Netbeans you set those options in : Netbeans installation etc netbeans.conf You should prefixe those options with -J and add them in netbeans default options see comments in netbeans.conf for more informations . Comment : OK none of the answers really helped but this one bought me the most time between restarts : Comment : try to icrease MaxPermSize to 512M or more beacuse garbage collecting permament hep will still not help if an application ties to store there more than it can contain the amount of alive permamanet objects exceedes permament heap capacity Comment : The arguments seemed to work for me byte code-analysis of rt.jar in my case however I did get the warning Please use CMSClassUnloadingEnabled in-place of CMSPermGenSweepingEnabled in the future .

Answer : We wrote some docs on how to work with configuration http : fabric8.io guide develop configuration.html . Generally speaking on kubernetes the use of service-discovery http : fabric8.io guide develop serviceDiscovery.html and kubernetes secrets avoids most of the use cases for environment specific configuration . Ideally we would use the same Continuous Delivery pipelines http : fabric8.io guide cdelivery.html to change code or configuration to ensure things are properly tested before they hit production .

Answer : The way we recommend integration and system-testing in maven with docker is via the fabric8 arquillian plugin http : fabric8.io guide testing.html . That takes care of creating a new namespace for the test and provisioning all the kubernetes resources then running your JUnit test case to run the assertions etc .

I will let a moderator move my question if needed Comment : @DoNhuVy Oh that looks perfect I will read asap .. . Answer : Here s a demo video showing how to create a Spring Boot microservice https : vimeo.com jbossdeveloper review 170830750 b3c8467593 in the Fabric8 Microservices Platform http : fabric8.io and having a complete Continuous Deployment pipeline http : fabric8.io guide cdelivery.html get created to do the following : .. . .. . package the code create the docker image and kubernetes manifest .. . perform system integration tests .. . deploy to the staging environment with rolling updates .. . wait for optional human approval .. . deploy to the production environment with rolling updates .. . .. . Any code or configuration change in the git repository kicks off rolling updates automatically - which is a form of hot deployment . e.g . if you are running 3 containers in production new containers are spun up with the new code and or config based on the rolling upgrade policy . Typically new containers start when they are ready old ones are taken down say 1 at a time or you can do them all at once if you prefer . The rolling upgrade is included in any service load-balancing so new containers only get invoked when they are ready . Given your use of OSGi you may want the containers to keep running and just mutate on the fly . Firstly the whole move to immutable infrastructure e.g . docker images means software gets simpler and easier to reason about . Rather than rolling new bundles code config in out on the fly you just make a new image and spin that up . Mutating on the fly leads to multi-threaded code having to stop and restart services on the fly which can cause all kinds of complex hard to reproduce bugs and resource leaks as you have large complex object dependency graphs of services starting stopping on the fly . On the Fuse team we ve wasted many man years fixing bugs in restart logic and I m sure there s still a zillion bugs hidden there in restarting OSGi services on the fly . So my preference really is to use a Continuous Deployment pipeline http : fabric8.io guide cdelivery.html to roll out all changes whether code or configuration . Sure there s some latency added between the time you make a change and the moment a process is processing a new request with the new code config - but you have more quality and reliability baked in . Plus its trivial to roll back . You can also easily do rolling upgrades of the change so you get fast feedback if the change breaks things for a small subset of your users traffic rather than a big bang . That being said if you still really really want production JVMs to reload code and or config on the fly without testing it first in a big bang approach with no easy rollback there are still some options available . They are described in the configuration microservices documentation http : fabric8.io guide develop configuration.html . Essentially it boils down to using a ConfigMap in Kubernetes http : kubernetes.io docs user-guide configmap or a git repository volume http : kubernetes.io docs user-guide volumes gitrepo in both cases the configuration is exposed as volumes files - the Java code can then watch the files and reload on the fly . You can do this via OSGi Config Admin or via Spring Boot http : docs.spring.io spring-boot docs current-SNAPSHOT reference htmlsingle howto-hotswapping - whichever development framework you pick really . Just remember the tradeoff of the benefits in latency from hot-reloading from the reduced quality increased bugs and operational issues of moving away from immutable infrastructure and Continuous Delivery Comment : Completely agreed especially in a Microservices world where turnaround times are supposed to be quick because of the smaller artefact footprints . It should to be affordable to restart whole micro apps in order to get to a well defined always reproducible state . And since it mirrors the way applications are operated in production its a more realistic workflow . But this only works really well if development roundtrip times can be kept short which is imho a key requirement . Comment : I agree that hot deployment is not necessary to have short dev cycles . I personally work with OSGi in the same way as James showed for spring-boot . I create fully packaged deployment units in an automated pipeline . The main difference is that I propose to not start with microservices but rather a modular application in one process . It is much simpler . Then if needed you split out the modules with different team or dev cycles as individual microservices .", "Question : I recently started working on a code base that uses fabric8 to manage containers pods services etc . in kubernetes .

Do you have any ideas why I cannot reach my basic fabric8 console Comment : try to ping curl port 80 .. . Answer : If you are trying to access a service on OpenShift remotely then you need to ensure you ve deployed a router added a Route . You can read more on routing in OpenShift at https : docs.openshift.com enterprise 3.0 architecture core concepts routes.html . In this case if you add a route with : .. . .. . cat EOF kubectl create -f - apiVersion : v1 kind : Route metadata : name : fabric8-console pec : host : EXTERNALLY RESOLVE DNS to : kind : Service name : fabric8 EOF .. . .. . As some extra info you cannot target ping at a port . Ping uses a different network protocol ICMP which doesn t have the notion of ports . Also both services pods don t respond to ping so you will not be able to ping them . If you re trying to check connectivity then you can use the nc utility : .. . .. . This will report connection success if the address port is reachable .

There are more standard ways to connect application tiers environment-variables and dns : http : kubernetes.io v1.0 docs user-guide connecting-applications.html accessing-the-service", "Question : I am interested in hearing as to whether there are any frameworks using kubernetes or otherwise that one can use to write end-to-end system tests with of a series of modules applications that talk to each other in a more complex system . Alternatively I d be very interested in hearing if it is possible to write system tests using kubernetes from a first principles approach . My use-case is that the modules in question may be written in many different frameworks and languages but they can all be dockerised individually . I know that fabric8 https : github.com fabric8io fabric8 claims to support system-testing using kubernetes and arquillian http : fabric8.io guide testing.html however that seems to have the distinct disadvantage that all the applications need to be written in java which is very much a no-go for me . Update : It does look like it is possible to write end-to-end tests in kubernetes for particular examples use cases see https : github.com kubernetes kubernetes issues 6183 . However this issue doesn t seem to have been touched for a while . Though this does give me some modicum of hope that what I m after is not impossible . Ideally I wouldn t mind being walked through pointed to work that might help me see an example of e2e tests for a hello world kubernetes example like k8petstore or simpler . In particular the relevant part of the kubernetes project seems to be https : github.com kubernetes kubernetes tree master test e2e . .. . Answer : FWIW you can use fabric8-arquillian to test stuff that are not written in java . The only thing that needs to be in java is the test case itself . Comment : I see that is helpful thank you .", "Question : I am using fabric8.io to orchestrate application containers in Kubernetes . I am looking to create a Service that manages a pod with a certain label on a certain port . Is there a specific example of the API that does this . I couldnt find it in the examples .. . .. . https : github.com fabric8io kubernetes-client blob master kubernetes-examples src main java-io fabric8 kubernetes examples FullExample.java L75 .. . .. . There dont seem to be javadocs available .. . Answer : I m using the same library and you re right the docs are a bit lacking in the creation department . I had to use Eclipse to kind of explore the API by hand because I couldn t find any explanation of this either . Here s how it works . So basically you use the KubernetesClient to create all objects . It will have methods services replicaiton controllers etc for each object and any actions associated with them . The second line loads your service definition file or String into a Service object . Then you use the client to create the object in Kubernetes . The KubernetesHelper object can load yaml or json . You can also use the ServiceBuilder object to build it programatically . EDIT : And after looking back through the answers tagged kubernetes I found this in a question asking basically the same thing : example to deploy docker image on kubernetes from java http : stackoverflow.com questions 33267107 example-to-deploy-docker-image-on-kubernetes-from-java", "Question : I try to get started with fabric 8 and open shift on docker .

Answer : Starting with WPF .. . .. . I personally work with a combination of Microsoft Visual Studio https : www.microsoft.com visualstudio eng environment and Microsoft Expression Blend https : www.microsoft.com expression eng elements editing . Blend is a WYSIWYG front-end for designing XAML-based interfaces for WPF and Silverlight applications and it s good for templates visual states and animation . .. . .. . Editing Templates .. . .. . If you are working with templates a nice tool is WPF Theme Editor http : www.devexpress.com Products NET Controls WPF Themes theme-editor.xml by DevExpress . It integrates with Blend and the tree browser and template hierarchy are very useful for locating styles . One thing you ll always find helpful is access to the actual structural templates for the elements . I usually find myself visiting the DevExpress WPF Controls http : documentation.devexpress.com WPF CustomDocument7875 website which has a very comprehensive list of libraries and controls . The Demo Center for DevExpress https : www.devexpress.com support demos is also a great downloadable app for extracting and editing templates . I find it particularly useful with complex elements like charts not included in Blend where you can toggle the visibility of elements and then move the code to your dev space . .. . .. . Creating Graphics .. . .. . For working with graphics themselves I found Microsoft Expression Design http : www.microsoft.com en-nz download details.aspx id 36180 to be quite good for drawing and exporting vectors into png WPF or Silverlight formats . It has a nice simple set of tools and you can import elements from vector . Also version 4 is free . .. . .. . Testing .. . .. . I just discovered this nice tool for testing live called Snoop https : snoopwpf.codeplex.com . It s open-source and it allows you to spy browse the visual tree of a running WPF application without the need for a debugger and change properties live . For all of these you will probably need at least a basic knowledge of how to write read WPF . I personally use all of the previous and write custom styles for custom elements .

To resolve such problems with Visual Studio or Blend simply delete LOCALAPPDATA Microsoft VisualStudio version ComponentModelCache or LOCALAPPDATA Microsoft Blend version ComponentModelCache respectively then restart your Visual Studio or Blend .

Am I correct in assuming it can be used for regular desktop applications too .. . Answer : At the moment Blend for Visual Studio does not have support for building WPF or Silverlight applications enabled . But it will with the next update . From that point on you will be able to design regular desktop apps using Blend again . Until than you could use Expression Blend 4 which is available to you if you have an MSDN subscription . You can read more about the upcoming update for Visual studio here http : blendinsider.com technical announcing-visual-studio-2012-update-2-ctp-2013-01-30 and download a preview . There s an earlier preview of Blend available that supports WPF too . You can read more about this on the BlendInsiders blog http : blendinsider.com technical announcing-blend-sketchflow-preview-for-visual-studio-2012-2012-08-15 . The only drawback with this preview is that it doesn t have a go-live license yet . It runs side-by-side with Blend for Visual Studio . Although it should be possible to build an application entirely in Blend I would recommend writing your code in Visual Studio and only work with you XAML in Blend . Update : With the release of Visual Studio 2012 update 2 support for WPF is added to Blend .

Does Blend create a lot of IE10 Windows 8 specific stuff in the markup styling or is it pretty standard stuff it generates Cheers Nick .. . Answer : HTML authoring in Blend is currently focused on creating Metrostyle apps for Windows 8 in HTML and CSS not on apps to run in browsers . The underlying Windows HTML CSS JavaScript platform is of course very standards-compliant and therefore Blend edits and generates standards-based HTML and CSS . Here are a few points of interest : The Blend design surface uses the same renderer that is used for Windows 8 apps at runtime i.e . IE10 . The Windows app runtime may render things differently than other browsers do just as different browser implementations have their differences . It s still standard HTML and CSS but WYSIWYG editing is based on the Windows 8 app runtime rendering . Windows 8 apps can be in different view states . In a running app view state switches cause media-queries and events to fire . There is special tooling in Blend to simulate view state and resolution DPI switching on the design surface for accurate design experiences . Web sites are generally intended to have scrolling pages of unlimited height . App UI in contrast will more often assume fixed height as determined by the size of the screen of the device the app is running on . The Blend design surface is designed for building apps . Interactive mode runs apps as Windows 8 apps . Blend does not edit loose HTML or CSS files it assumes a project file . The project templates supplied are for Windows 8 apps . Blend s CSS property editor focuses on the set of CSS properties and values that is supported in IE . The vast majority of CSS properties and property values present in IE are the same as everywhere else but there are a few minor differences just like between other browsers . There are a bunch of CSS features supported in IE 10 that are proposed standards but not finalized . The W3C requires that browsers use vendor-specific prefixes for such properties and property values . This includes things such as CSS Grid Flex box Transitions and Transforms and several others . For such properties Blend will only understand and generate the Microsoft-specific vendor prefixes . Part of the Windows 8 HTML UI platform is the WinJS toolkit which is just a JavaScript library which provides controls and other useful building blocks . Blend includes special tooling for several features of WinJS such as controls or fragments . Using any of these features will create markup that relies on the availability of the WinJS toolkit but use of WinJS is of course not mandatory . Cheers Lori Dirks Blend Team Community PM Comment : It would be nice if Microsoft allows blend to create plain web sites . This allows devs to maintain consistency between windows-store-apps and their web sites . By restricting winjs use It seems ms does not want to promote Winjs .", "Question : I have Blend 3 Final and Visual Studio 2010 Beta 1 installed and I need to develop in VS 2010 with .net-4.0 and design my end-user UI in Blend but Blend 3 can t open my projects What should I do : .. .

Answer : Blend does not like mixed projects -- they won t build and the design surfaces stop working . And if that didn t kill it for you Blend does not support solution folders it just strips them right out and flattens everything . You generally work with a project in Blend and work with the solution in Visual Studio . Supposedly this might get better with WinRT and Windows 8 but I m not holding my breath . Comment : so basically there s no way of bridging the two In the sense that I would like to have the gui project blend able and the rest datamodel interfaces business logic in visual-studio while keeping the gui project a bridge between the 2 so that both developers and designer work with blend on gui while developers work exclusively on the others . Comment : In this case I don t think there is a good clean way to bridge the two . CLI has been a red headed step child for a while now . This is just another case of that same attitude from Microsoft IMO . Comment : thanks . I will take this as the answer . However to workaround the broken designer I found out that adding this line to your csproj file helps : ProjectGuid C9319776-9508-438A-9365-F0584BC7B044 ProjectGuid .

Comment : I had this problem in Visual Studio 2011 and I solved it by changing the problematic StaticResource Foo into DynamicResource Foo . Hope this helps someone . .. . Answer : There are two known occurrences where this can happen . If you change to Blend before you built the application the DLLs are not available yet and this error can be seen . Building the application solves the issue . There is a bug in Expression Blend where if you are placing a user control in another user control or Window in WPF and the inner user control uses a global resource the global resource cannot be found . In that case you will get the error too . Unfortunately I do not have a workaround for the second point as it is a Blend bug . I hope we will see a resolution for that soon but it seems to be still there in Blend 4 . What you can do is .. . .. . Ignore the error when working on the outer user control . When you work on the inner user control you should see the design-time data fine not very satisfying I know . Use the d : DataContext to set the design-time data context in Blend temporarily .

Comment : Thanks for the suggestion . Comment : Careful that book is for Blend 2 and VS 2008 not 4 and 2010 . .. . Answer : Solutions are the same for Visual Studio and Expression Blend . You can open your solution through the file menu in expression-blend or by right clicking on a xaml file in Visual Studio and select Open In Expression Blend .

But when I want to see what s going on with margins and layout and stuff I always use Blend . Most often I have Visual Studio and Blend open side-by-side and I keep switching back and forth . Because Expression Blend uses the same solution you don t have to worry about event handlers and such . When they are in-place they stay in-place . Unless you delete the control the event is attached to of course . Creating a solution can be done in both tools but I start most projects in Visual Studio . There are however a few Project templates that can t be found in visual-studio . For example the Databound Application project type .

Answer : Like you said if you don t have any other alternative with grunt I think that the need of using both task runners is real until an equivalent solution is found or created . You should of course take care of the possible overrides and conflicts that comes with each task you add-in gulp and to me never mix your watchers . Always choose to use them in one or the other runner cause of the infinite loops . Even if in this case with gulp-protractor-qa you are watching files there is no dependent task which runs and nothing is written so you should be fine . Also since the new dependencies will mainly be the dev ones the performance of your deployed app will be very slightly affected or not except if you run your tests on each deploy that may take a little longer to install them .", "Question : I want to integrate gulpjs into Php Framework CakePhp 2.x what would be best practice to use gulp to achieve following feature in CakePhp : .. . .. .

In reality you will probably not create these gulp tasks manually but install them using scaffolding techniques with tools such as Yeoman . How to use with Node.js .. . .. . As the name of node-sass implies you can write your own node.js scripts for transpiling . If you are curious check out node-sass project page . What about libsass Libsass based solution for transpiling sass wasn t as straight-forward as the Ruby based one . Libsass is a library that needs to be built by an implementer such as sassC or in our case node-sass . Node-sass contains a built version of libsass which it uses by default . If the build file doesn t work on your machine it tries to build libsass for your machine . This process requires Python 2.7.x 3.x doesn t work as of today . In addition : .. . .. . LibSass requires GCC 4.6+ or Clang LLVM . If your OS is older this version may not compile . On Windows you need MinGW with GCC 4.6+ or VS 2013 Update 4+ . It is also possible to build LibSass with Clang LLVM on Windows . Grunt or Gulp I tried Grunt but due to lack of my knowledge I couldn t force it to use the built file that comes with node-sass package . So it fetched the whole libsass raw files per project and built it from the scratch . Each grunt-sass folder became more than 80MB in size with dozen of files which is not efficient IMHO . I am sure there is a way to avoid this and hopefully someone will enlighten me in the comments . Comment : Upvoted for node-sass solution .

I can imagine this would hit me again when I would need different suitable plugins in both build systems and would have to make a choice : try to sit on two chairs .. .

You have an option to run grunt tasks from gulp https : www.npmjs.org package gulp-grunt or vice versa gulp tasks from grunt https : www.npmjs.org package grunt-gulp . First way looks more efficient because gulp is much faster than grunt . Consider moving to gulp entirely many grunt-plugins have native gulp counterparts .

If anyone has any ideas thanks in advance .. . Answer : FWIW it seems that using the cwd parameter on gulp-nodemon s configuration actually sets the entire gulp cwd to that directory . This means future tasks will be executed in the wrong directory . I had this problem when running gulp-watch tasks on my frontend server at the same time as nodemon tasks on my backend server in the same gulpfile there was a race-condition wherein if the nodemon command was executed first the frontend stuff would actually build into Home backend frontend instead of Home frontend and everything would go pearshaped from there .

Within my JavaScript files I have a mixture of pre-minified and non-minified files .

The following is my Gulp task definition : .. . .. . This works in that I get a concatenated file but the non-minified files remain unminified pre-minified files are still minified -- as expected .

Answer : Have you tried this Comment : Hey yes that was my original code but as far as I can tell I just get one concatenated file at that stage so it just minifies everything . Comment : Isn t that what you want The gulp-useref plugin concatenates the files by default so you would need to use the no-concat option to split them out and then concatenate them again somewhere else . Comment : Ultimately yes . However I want to process some of those files prior to the concatenation -- hence the use of the transform stream github.com jonkemp gulp-useref transform-streams https : github.com jonkemp gulp-useref transform-streams Comment : the docs suggest that transform streams are for this very purpose Transform assets before concat . -- am I misunderstanding Comment : Minification doesn t really fit that use-case though . That use-case is more for something like transpiling css or javascript files before concatenating them . As you can see the gulp task above is a much simpler way to do it if you just want minification .", "Question : I am using visual-studio task runner 2015 to run a Gulp task bound to before build . I have set it up so that when the gulp tasks fails it sends exit code 1 and at the end it says Process terminated with code 1 . however the build continues . This will cancel the build in team city so seems an issue linked Task Runner inside visual-studio . How can I prevent the build from taking place if it exits with a code other than 0 .. . Answer : You are correct in that this seems to be a Task Runner issue . The task runner does not communicate with MSBuild to stop a build if a BeforeBuild task fails . To get around this you can run your Gulp task via the project s pre-build event instead of via the Task Runner bindings . Set the pre-build event .. . .. . For class libraries you can access Build Events by right-clicking your project and selecting Properties - Compile - Build Events.. . . For web projects they are located at Properties - Build Events . Here is the command I used to call the Gulp task in pre-build event which will prevent the MSBuild from running if it exits with a failure : .. . .. . gulp -b ProjectDir --gulpfile ProjectDir gulpfile.js my-task .. . .. . This command calls Gulp passing absolute paths for working directory and gulpfile.js . Notes : .. . .. . I found all kinds of context and working directory issues trying to use a more straight up command like gulp my-task . ProjectDir is one of the Macros for Build Commands https : msdn.microsoft.com en-us library c02as0cs.aspx . It is assumed that Gulp is installed globally : npm-install -g gulp . See jonas.ninja http : stackoverflow.com users 3688464 jonas-ninja s answer http : stackoverflow.com a 36064728 120783 for how to build this install into the command or for an alternative that does not require the global dependency . Comment : Had not thought of this option thanks", "Question : Short of it : started using Gulp recently convert from Grunt and am trying to use both Gulp s default watch task not gulp-watch from npm for SASS JS HTML and gulp-nodemon from npm to restart an Express server upon changes . When running just gulp-watch it works fine and when running gulp server for nodemon that works fine . However using both together shown below in the configuration of the default task the watch stuff isn t working . The task is running and on the CLI gulp shows Starting and Finished for the watch tasks but the files don t update . Relevant task configurations : .. . .. . Concat javascript : .. . .. . Nodemon restart on changes to express app : .. . .. . Watch javascript changes and run js : app for concat ing . .. . .. . Default task to initialize gulp-watch and nodemon simultaneously : .. . .. . If anyone has any ideas thanks in advance .. . Answer : gulp.run calls have been deprecated https : github.com gulpjs gulp issues 193 issuecomment-33277999 so I d try a different approach . Since you re already using gulp may I suggest giving gulp-nodemon https : www.npmjs.org package gulp-nodemon a try As per gulp-nodemon documentation https : github.com JacksonGariety gulp-nodemon onevent-tasks you can pass it an array of tasks to execute : .. . .. . UPDATE : Here s the full gulpfile.js file together with a working sample on github https : github.com gfestari gulp-sample . This way you spawn the watch task upon nodemon s start and ensure that the watch task is again triggered whenever nodemon restarts your app . EDIT : seems you should be calling the on- change event from gulp-nodemon https : github.com JacksonGariety gulp-nodemon onevent-tasks which will handle compile tasks before the restart event triggers . Comment : gaston - the setup i m using is already w gulp-nodemon actually however i didn t configure it so that it would restart the watch task on change . i ll give it a go and let ya know . thx Comment : so wasn t able to get it to work that way . what s confusing me : if I run the nodemon task like so : gulp.task demon watch function nodemon .. . both nodemon AND the watch task will execute and show output on a file changing - but the changes from the watch task aren t written to the appropriate files . like the task is run but its not piping the changes to disk . Comment : @jiveTurkey I ve updated my answer with the full gulpfile and left a working github sample https : github.com gfestari gulp-sample . Basically this will start nodemon and link it with a gulp-watch task to monitor file changes . Let me know how it goes Comment : Thanks for your answer Gaston . This worked like a charm and really helped me In my gulpfile.js I removed .on change watch because the watch task was running twice once right before the change and once again after the server restarted . Comment : @Gaston - thx again for the help approach above didn t solve the issue unfortunately although it put me on the right track : . It seems that running either a watch task or a nodemon task independently works fine . However if the nodemon configuration has cwd : something relative here that will influence the paths used by the watch tasks . You d think that they d be completely isolated but for some reason the cwd property in nodemon will influence paths in gulp.watch .. . configurations . Solution was to make paths absolute . Not ideal . Will post explanation in full below .", "Question : null .. .

Answer : Other languages have runtime time information sufficient to support dynamic casting and yet nothing that could be described as reflection C++ being an obvious example . So reflection refers to additional capabilities beyond merely discovering the type of an object . To reflect on an object implies the ability to walk its members for example . Comment : It would be more correct to say that reflection is parsing the members of a class than those of an object since you do not need to have an instance alive . Also reflection enables discovering what classes you have in an assembly not only members and other info of a class . Comment : @Danny Varod - Not all languages have classes or assemblies . Comment : C++ has classes and libraries Java has classes and packages . Object Oriented Programming does define the difference between an object and a class . Comment : Also C++ could not have reflection - since the binary files do not have the required info embedded in them . - That is why you need h files to consume a binary and lib files to link expect from the assemblies to run .

In Perl 6 I know about the introspection methods .WHO .WHAT .WHICH .HOW and .WHY but these are at a class or object level . How do I find out what s inside an object and what I can do to it .. . Answer : How do I find out what s inside an object and what I can do to it You mentioned that you already know about the introspection methods - but are you aware of what you can find out by querying an objects metaobject available from .HOW There is a shortcut for querying an object s metaobject a . b translates to a.HOW.b a . The methods and attributes for Article are themselves objects - instances of Method and Attribute . Whenever you call .say on an object you implicitly call its .gist method which is meant to give you a summarized string representation of the object - i.e . the gist of it . The attributes of the builtin Str type appear to be of type BOOTSTRAPATTR type - which doesn t implement the .gist method .

Thanks all .", "Question : For many framework development we need to instantiate class by reading qualified class names from a config file . There are different introspection strategies and dedicated libraries like Objenesis geared towards it . However for classes with no default constructor overloaded I believe no introspection works if we do not know the signature of the overloaded constructor . The non standard approach is to use sun.misc.Unsafe class to allocate . This is what I understand . Is that a correct understanding Then there s a problem with that as super classes are not instantiated by using Unsafe . But I thought Unsafe is the closest to whatever C code new-operator invokes at least a part of it . So the question is do we have Java ways of instantiating a object the way new-operator does by some form of introspection when the only information we have is the qualified-name of the class and of course that is present somewhere in the classpath Comment : You can always inspect the available constructors and see if you have any values you can pass to them . Dependency injection frameworks will do this for autowired constructor-injected objects - the assumption is that the objects you re creating mostly need other objects from your codebase not generic parameters like strings and that the DI container also manages these dependencies and thus knows how to create them . Comment : Do you want to get an initialized object a constructor invoked or uninitialized one no constructors and initializers invoked fields have default 0 or null values Comment : I want to have the superclass members initialized the same way . So is that allocation of an object on the heap and instantiation of its members which in turn might need allocation are part of different strategies @millimoose What you are saying is correct for a DI framework since as you said it is mostly objects from your codebase .

I realize I m taking a lot of heat for this question so let me clarify what I was getting at . Yes you are all right for-in fast-enumeration does not perform introspection but why not If I m specifically designating a type such as NSNumber or NSString why doesn t the for in loop perform a kindOfClass method with the type you designated rather than casting an object as the incorrect type In the example above is it not intuitive that I would only be iterating over the NSNumbers in the array I suspect that the answer is performing introspection on each item in an array may negate the performance enhancements of fast-enumeration But could this not be solved with using id when we want dynamic-typing and explicit types when we d like to perform introspection Comment : What happened when you tried it Comment : Suggestion : take the time to study and understand iteration enumeration this is not introspection .

The thing is I don t do this all that often and tend to forget APIs when that happens I d rather let the code run on an example directory and dump all of the properties in an object so I can remind myself what is available where obviously I d like to dump in order to avoid having to code custom printouts . However I m aware of the following : .. . .. . list out all methods of object - perlmonks.org http : www.perlmonks.org node id 884054 884061 .. . Out of the box Perl doesn t do object introspection . Class wrappers like Moose provide introspection as part of their implementation but Perl s built-in object support is much more primitive than that . Anyways I looked into : .. . .. .

Then I looked into IO : : All which I like because of utf-8 handling but also say socket functionality which would be useful to me for an unrelated task in the same script and I was thinking I d use this package instead . The problem is I have a very hard time discovering what the available fields in the object returned are e.g . with this code : .. . .. . .. .

In general you can t do this with a dynamic language like Perl . The package might define some methods that you can find but it can also make up methods on the fly that don t have definitions until you use them . Additionally even calling a method that works might not define it . That s the sort of things that make dynamic languages nice . : .. . .. . Still that prints the name and type of the field - I d want the name and value of the field instead . So I guess my main question is - how can I dump an IO : : All result so that all fields including stat ones are printed out with their names and values as is mostly the case with File : : Find : : Object I noticed the IO : : All results can be of type say IO : : All : : File http : search.cpan.org frew IO-All-0.57 lib IO All File.pm but its docs defer to See IO : : All http : search.cpan.org frew IO-All-0.57 lib IO All.pod which doesn t discuss IO : : All : : File explicitly much at all . I thought if I could cast contentry to a IO : : All : : File maybe then mtime etc fields will be printed - but is such a cast possible at all If that is problematic are there other packages that would allow introspective printout of directory iteration results - but with named fields for individual stat properties .. . Answer : Perl does introspection in the fact that an object will tell you what type of object it is . You can also see if an object can do something : .. . .. . What Perl can t do directly is give you a list of all the methods that a particular object can do . You might be able to munge some way.Perl objects are stored in package namespaces which are in the symbol-table . Classes are implemented via Perl subroutines . It may be possible to go through the package namespace and then find all the subroutines . However I can see several issues . First private methods the ones you re not suppose to use and non-method subroutines would also be included . There s no way to know which is which . Also parent methods won t be listed . Many languages can generate such a list of methods for their objects I believe both Python and Ruby can but these usually give you a list without an explanation what these do . For example File : : Find : : Object : : Result which is returned by the next obj method of File : : Find : : Object has a base method . What does it do Maybe it s like basename and gives me the name of the file . Nope it s like dirname and gives me the name of the directory . Again some languages could give a list of those methods for an object and a description . However those descriptions depend upon the programmer to maintain and make sure they re correct . No guaranteed of that . Perl doesn t have introspection but all Perl modules stored in CPAN must be documented via POD embedded documentation and this is printable from the command-line : .. . .. . This is the documentation you see in CPAN pages in http : Perldoc.perl.org and in ActiveState s Perl documentation . It s not bad . It s not true introspection but the documentation is usually pretty good . After all if the documentation stunk I probably wouldn t have installed that module in the first place . I use perldoc all the time . I can barely remember my kids names let alone the way to use Perl classes that I haven t used in a few months but I find that using perldoc works pretty wall . What you should not do is use Data : : Dumper to dump out objects and try to figure out what they contain and possible methods . Some cleaver programmers are using Inside-Out Objects http : www.stonehenge.com merlyn UnixReview col63.html to thwart peeking toms . So no Perl doesn t list methods of a particular class like some languages can but perldoc comes pretty close to doing what you need . I haven t use File : : Find : : Object in a long while but going over the perldoc I probably could write up such a program without much difficulty . Comment : Thanks for the answer @DavidW - all of these are details that I don t usually keep in mind so it s great to have them written down Part of this is not only for forgetfulness but also to print out the values so I can see if some conditions I d be about to write make any sense at all.. . I am trying to avoid writing a specialized printing function and I just learned of Moose so I thought maybe I can have a Moosified class that extends IO : All where I would just redeclare fields from the docs i.e . mtime and then they d hopefully print. . but I get stuck w AUTOLOAD : Cheers Comment : @sdaau The m obj command in the perl debugger does a reasonable job of listing what methods are available on a particular instance or class .

I tried the same thing by subclassing my own non-Moo based class instead and the object created from this subclass is of the correct type . What could be the reason for this difference Comment : Nice find . I tested with DateTime worked like a charm . .. . Answer : new constructors need to be written in a way to observe the caller s actual class which works with subclassing but they can also hard-code which class they create objects with .

So how do I achieve it and is wordnet suited for what I want to do .. . Answer : What do you mean by synonym In WordNet you have similar words representing the same concept under this term call the Synset . To get synonyms in the coverage of your example you would require more than wordnet possibly some semantic similarity methods to extract the other words . I couldn t give you a JAWS explanation of what i mean above but from WordNet in NLTK interface for python . You can see that WN is insufficient for the coverage you want .

What would you recommend for my app Is it possible to use a Perl library from a java app via some bindings Thanks Mulone .. . Answer : I use JAWS for normal wordnet stuff because it s easy to use . For similarity metrics though I use the library located here http : code.google.com p xssm source browse trunk XMLSchemaMSM lib edu.sussex.nlp.jws.beta.11.jar r 140 . You ll also need to download this http : code.google.com p xssm source browse trunk commons-lib WordNet r 151 WordNet 3.0 folder containing pre-processed WordNet and corpus data for it to work . The code can be used like this assuming you placed that folder in another called lib in your project folder : .. . .. .

Does someone have some recommendations for me Thank you a lot Bests M .. . Answer : As OWL files are RDF any RDF triplestore will do for storing them - though not every triple store will support OWL reasoning but then again you might not even need that . Some popular open-source choices for RDF storage querying are OpenRDF Sesame Apache Jena OpenLink Virtuoso Redland 4store and dotNetRdf . It s probably worth pointing out that several of these e.g . Sesame Jena dotNetRdf are storage-neutral APIs which means that several other open-source commercial triplestores can be accessed via them . So which triplestore API you pick depends on your requirements in terms of things like ease of use scalability reasoning support required and just generally which one you think looks cool . Have a look at this page http : answers.semanticweb.com questions 397 what-are-specific-triplestore-strengths-and-weaknesses for an overview of some of the strengths and weaknesses of the various offerings . Comment : I d also add that you have the option of using a dedicated OWL reasoner such as Pellet or HermiT . These won t provide persistent-storage and won t scale to the same level a database will but they ll probably give you the best performance for reasoning and are your only options if you need DL reasoning .

Answer : I see that SPARQL and RDF are all about standards which is cool .

Comment : yes thats exactly what I meant . fyi people sometimes refer to a database that is implementing the property graph model as a property graph which is different than a triplestore containing RDF triples because in a triple store essentially all verbs are edges whereas the property graph has the distinction between attributes that identify an entity properties and attributes that identify a relationship between entities an edge . property graph enthusiasts tout its strengths in network-analysis and all of the popular algorithms that go along with it .

Comment : fwiw property graphs are easily represented in RDF so you can use a triple store as the backend and use either model you want", "Question : null .. . Answer : With a relational-database I can roughly visualise in my mind how the data on tables would be stored referenced and updated . However when I try to imagine this going on in a triplestore database I can t figure out how this would be happening without ending up with very fragmented storage of the data . Considering the below conceptual triples : .. . .. . .. . Elephant is a pachyderm .. . Eagle is a bird .. . Monkey is a mammel .. . .. . .. . ...and the following conceptual inferences : .. . .. . .. . pachyderm is a animal .. . bird is a animal .. . mammel is a animal .. . .. . .. . From what I can guess in order to identify each of Elephant Eagle and Monkey as animal s then we have to run the triplestore through a Reasoner https : en.wikipedia.org wiki Semantic reasoner . The way I m imagining it is as a cross between defragmenting a hard drive and performing a join in SQL to give : .. . .. . .. . Elephant is a pachyderm .. . Elephant is a animal .. . Eagle is a bird .. . Eagle is a animal .. . Monkey is a mammel .. . Monkey is a animal .. . .. . .. . If it s something along these lines then is a triplestore effectively some sort of massive normalised three field table that gets written out in full by the reasoner Comment : This is probably too broad for Stack Overflow . The short answer is yes a triple store s data is a massive three field table . Triple stores are typically going to efficiently index that in various ways to make query efficient . Reasoners might be built-in to a triple store or compatible with it but conceptually it s a distinct and optional thing . A triple store just needs to store triples . Comment : Oh isn t that an oversimplification . Granted some triplestores use a relational model under the hood but aren t there any that actually use a graph model Or something in between Comment : @TomaszPluskiewicz But conceptually what s the difference A graph of labelled edges is isomorphic to a set of triples source label destination . So yes a triple store is also a graph . But as far as the user is concerned the implementation doesn t really matter a triple store just has to be able to store triples .

The possible advantage of this is that it allows you switching to a different database if you so require without major changes to your code .

Answer : An RDF triple store is a set of triples so the same triple cannot be present twice by definition .

Answer : One should keep in mind that any particular triple may have different metadata than other - otherwise identical - triples . Metadata such as the original source of the triple possible strength of connection information etcetera .

It s simply an R D exercise to see what I can do . I like the look of OWLIM http : www.ontotext.com owlim but some basics are failing me . How exactly is one meant to build and then use an OWL ontology Do you build it with something like Protege http : protege.stanford.edu then import it into your repository Or is the ontology a byproduct of the software you develop to communicate with the repo It s a newbie question but I m just not sure where OWL fits into the grand order of things.. . I wouldn t ask the question if I hadn t looked around for guidance . .. . Answer : I don t think there s a specific way you have to use OWL http : www.w3.org TR owl2-overview to build an application . Hell you don t even need to use it to have built a semweb application . Generally I think there s a couple ways people tend to use OWL . I think one of the primary ones is for reasoning . They define concepts important for their application using one of the OWL2 profiles http : www.w3.org TR owl2-profiles and then use a reasoner http : en.wikipedia.org wiki Reasoner to infer new knowledge based on their ontology . There is even some work now in using OWL ontologies as schemas for integrity constraints . In other cases people use it as a documentation artifact to just be able to outline what it is that is in their data but they don t use it more formally than that . There are some piecemeal use cases in between and there are similar uses for RDF schemas http : www.w3.org TR rdf-schema which can be use like OWL ontologies just with a lower level of expressive-ness or something like SKOS http : www.w3.org 2004 02 skos which can be used to simply define a taxonomy within your application without any formal expressivity attached to it . Getting Protege http : protege.stanford.edu going is a good start . That will let you explore some of the basics of building an ontology and most of the reasoners are available as plugins so you can also explore how you can build your ontology and what kind of inferences you can get as a result . Once you have an ontology if you want to use it for something other than documentation ie reasoning you ll have to load it into a reasoner Pellet http : www.racer-systems.com Fact++ http : owl.man.ac.uk factplusplus RacerPro http : www.racer-systems.com HermiT http : hermit-reasoner.com or a database that does OWL reasoning Stardog http : stardog.com OWLIM http : www.ontotext.com owlim . If you re not worried about reasoning then you can drop it into any triplestore out there access it via Sesame http : openrdf.org or Jena http : jena.sourceforge.com if you re using Java and still be able to query the explicit facts via SPARQL http : www.w3.org TR rdf-sparql-query . So I guess the short answer is that there is not a correct way to use OWL it gets used in a variety of different capacities .

Answer : If your legacy iText code can produce a bold font then it seems likely that the TTF file does actually contain a bold variant even if Flying Saucer doesn t use it . You may be able to use the bold variant in Flying Saucer if you specify the exact name of the bold variant in your CSS stylesheet . For example : .. . .. . You should be able to find the exact name of the font by opening a PDF generated by the legacy code in Adobe Reader . Go to File -- Properties.. . -- Fonts to see a list of all the fonts in the document . There will probably be a myfont entry as well as a myfont bold entry or similar . Use the latter in your stylesheet .", "Question : I was wondering what steps were needed to render Asian characters using the java based xhtmlrenderer flying-saucer library I am wanting to render the following : .. . .. .

I ve spent many hours going through flying saurcer code but only when i saw your snippet i realized that woring with itext directly would be much more easy . Thank you . .. . Answer : I m no expert but if your font doesn t have a bold variant then Flying Saucer may simply not make it bold . When you programmatically make the font bold you re using a font class that could be behind the scenes making the font bolder on its own using some kind of internal mechanism . A good example of this in the real world is Photoshop : if you have a font that doesn t have a bold variety you can t make it bold but Photoshop has a simulated bold option that will go in and thicken up the symbols without really using a true bold face . A good means of diagnosing this for sure would be to switch which font you re using in Flying Saucer but keep the same document . If the new font is also not bold then the problem is less topical . If it does become bold then it is because there is no bold version of your font . Hope this helps . Comment : flying-saucer uses itext to generate the pdf . i was assuming that flying-saucer would use the same mechanism ie font.setStyle to apply the bold transform . clearly i am wrong and i don t dispute your answer in fact i agree 100 however i am looking for a solution not an explanation . my next stop is going through the flying-saucer source code however i d pay 50 rep for someone else to do this thanks anyway .

Comment : Thanks - I m discovering this as well have since found even more example flying-saucer code showing the browser component displaying the glyffs on screen but which still fail to render on PDF using iText . .. . Answer : To support the big character set you need to specify a font file that has all those characters in it . Once you ve picked a font file you ll need your application to point to that file . I ve found that just putting the font files in your font s directory doesn t work . Try embedding the font too eg . This link http : www.sino.uni-heidelberg.de edv sinopc chinese 5Ffonts.htm has quite a few font files .", "Question : I have a project where I want to be able to format xhtml documents into both PDF format and Docx format . I ve been using flyingsaucer to format PDF documents for some time and always had to use an older version of iText for compatibility reasons . Now that I m using docx4j I need to update iText to a more recent version or it won t work . FlyingSaucer xhtmlrenderer R8pre2 uses iText 2.0.8 .. . docx4j 2.8.0 uses iText 2.1.7 .. . .. . I can only use one iText library but whichever one I use I end up with compatibility issues for either flying-saucer or docx4j . At the moment the problem seems to come down to one particular method com.lowagie.text.pdf.BaseFont.getCharBBox which in one version takes a char parameter and in the other it takes an int parameter . I think I may have to download sources for either flyingsaucer or iText I think they re both open-source and fix this myself not something I ve done before but I think I could manage but I can imagine I m not the 1st person to run into this problem and perhaps there s another way around it or someone else has already forked one of the projects to resolve this sort of issue . .. . Answer : Disclosure : I work on the docx4j project .. . .. . docx4j 2.8.0 only uses iText because it is required by our fork of Flying Saucer https : github.com plutext flyingsaucer which does the XHTML import . In that fork I added docx related stuff and removed some stuff we didn t need . It s possible that in the future we ll offer this back to Flying Saucer - it s a matter of having the time . In the meantime I mention for completeness that you can have the real Flying Saucer and our fork on your class path at the same time since our fork is re-packaged . Back to your question FlyingSaucer proper now has the same 2.1.7 dependency https : github.com flyingsaucerproject flyingsaucer blob master flying-saucer-pdf pom.xml so if you are able to use the current sources that should address the issue you have raised . Comment : I tried using the flying-saucer fork used by docx4j but unfortunately the pdf files produced seemed to be corrupted Comment : I couldn t find a version of the flying-saucer R9 jar in any repositories online so had to download the sources from github and package them up myself .

I have beginner-intermediate closer to beginner knowledge of programming in jython but that is on a computer with jython already installed .

Comment : So what exactly is the problem you re encountering Is there an error being displayed Comment : I just don t know how to run the program . I thought there would be an executable so I just don t get how to start Jython . Basically my problem is I m being stupid . .. . Answer : That command is exactly how you run Jython and without providing any additional arguments the Jython interpreter will start where you can type out functions and run them . If you want to run Jython with a single command there should be a jython.bat file located somewhere under the Jython installation directory . Jython does not have a true executable because it is run through Java . The jython.bat file is the closest you ll get to an executable because it is a batch script which runs the jython.jar file using a command nearly identical to yours with Java . jython.bat should be located at one of the following locations : .. . .. . NOTE : The jython.bat file requires a standard Java installation . Comment : This worked it turned out Java was in the wrong place .

The sphinx-build command was not found snip .. . .. . It then recommends setting the SPHINXBUILD environment variable and even the PATH . I already have these two environment-variables set proven to myself by calling echo PATH and echo SPHINXBUILD . This is where I get stuck . It appears that the files that Sphinx uses sphinx-apidoc and sphinx-build in this case which are in the C : path to jython bin directory do not have any file suffixes . When called directly from Jython they work as expected see point 2 above however when called as part of another process e.g . make html they are not recognised and the execution fails see points 1 and 3 above . Does anyone know the what why and most importantly how to fix of this problem My setup process is on an unnetworked Windows 7 computer . Jython 2.5.2 was installed using the Jython installer . Then each of the following packages except setuptools was installed by extracting it locally and then running jython setup.py install in its extracted directory : .. . .. . 1 . setuptools : by calling jython ez setup.py with setuptools-1.4.2.tar.gz in the same directory so there is no attempt to download it .. . 2 .

Answer : I have managed to get it working . The problem was that the manual installation and the use of Jython meant that certain environment-variables that were expected were not in-place . Also the use of Windows 7 and I believe MS Windows in general means that Python scripts without an extension cannot be run without calling them explicitly through Jython Windows doesn t check for shebangs . Finally file associations had not been set up as happens automatically with CPython installation but has not happened with Jython . For anyone else with similar problems the following setup works for me : .. . .. . Locations : .. . .. . Java Runtime : C : Java jre7 .. . Jython : C : Jython jython2.5.2 .. . .. .

Append .py .PY to the PATHEXT system environment variable . This will make it possible to execute Python files without having to provide their .py extension . N.B . This does not make it possible to run Python files that do not have a .py extension . File Extensions : .. . .. . Rename the four Sphinx commands to include .py extensions . This is remarkably difficult with vanilla Windows 7 as it does everything it can to distance the user from such low-level details as file extensions however the rename command at the command-prompt does the job : type ren sphinx sphinx .py when in the Jython bin directory . It should now be possible to call sphinx-apidoc or similar from anywhere .

Just use Qt 5 and that means switch to it if you had not done so yet . You will then get access to the qt json classes in QtCore http : doc.qt.io qt-5 json.html all of a sudden . Basically you will have access to these classes : .. . .. . QJsonArray Encapsulates a JSON array .. . .. . QJsonDocument Way to read and write JSON documents .. . .. . QJsonObject Encapsulates a JSON object .. . .. . QJsonObject : : iterator QJsonObject : : iterator class provides an STL-style non-const iterator for QJsonObject .. . .. . QJsonObject : : const-iterator QJsonObject : : const-iterator class provides an STL-style const-iterator for QJsonObject .. . .. . QJsonParseError Used to report errors during JSON parsing .. . .. . QJsonValue Encapsulates a value in JSON .. . .. . Here you can find a very good example about the usage of these classes more or less : .. . .. . JSON Save Game Example http : doc.qt.io qt-5 qtcore-json-savegame-example.html .. . .. . If you have the Qt 4 series or older you could try to backport these classes if no one had not done so . The overall advantage of these classes is that they are extremely fast compared to other libraries like qjson 4-5 times or even the libjson library written in C This is possible due to the binary format it uses internally to speed up the read and write operation .", "Question : null .. .

Comment : look this up stackoverflow.com questions 7804955 http : stackoverflow.com questions 7804955 heterogeneous-containers-in-c .. . Answer : What is the equivalent of QVariant in C++ The equivalent in C++ is called QVariant . Semi-joke aside it is probably the closest to union but QVariant is so much more than that meta types CoW etc . Actually sharing implicitly is forbidden these days in STL so that is another reason why you would not find anything like this off-hand . I would suggest to make notes to yourself what functionality exactly you need from a QVariant and make a judgement call whether it is actually worth dropping QtCore . This is just a friendly reminder from the documentation http : doc-snapshot.qt-project.org qt5-5.4 qvariant.html details : .. . .. . The QVariant class acts like a union for the most common Qt data types . .. . Because C++ forbids unions from including types that have non-default constructors or destructors most interesting Qt classes cannot be used in unions . Without QVariant this would be a problem for QObject : : property and for database work etc . However since C++11 types with constructors and destructors are allowed . You have another question in here to ask from yourself : .. . .. . Do I want to support everything that Qt does or am I happy to require at least C++11 To be fair you could also look into the following boost variants below but then you end up using boost instead of QtCore after the porting . This is another judgement call for yourself . They are not replacements for each other neither technically nor compatibility wise . Boost in this case is a build time dependency while QtCore is a runtime . Qt would guarantee binary and source compatibility during the life cycle of the same major version while boost may not do the same for such a long period as QtCore does . Either way none of these options are pure STL solutions in the end of the day the way I think you wanted it to . Boost.Any http : www.boost.org doc libs develop doc html any.html .. . .. .

Comment : @Tay2510 : it is not completely joke . If one wants to reinvent QVariant in C++ one needs to write QVariant from scratch . It is telling to tell that there is no such an alternative as it satisfies the use-case what it does . Therefore if one exactly needs one needs to use QVariant . All the rest is compromise not the same .", "Question : null .. .

I was expecting an output similar to this http : www.cplusplus.com reference typeinfo type info name i.e . int QString double etc...but I understand this is totally compiler dependent . Comment : @LaszloPapp yes and I switched to QVariant thanks : .. . Answer : You could use this http : qt-project.org doc qt-4.8 qvariant.html typeName : .. . .. . const char QVariant : : typeName const .. . .. . Returns the name of the type stored in the variant . The returned strings describe the C++ datatype used to store the data : for example QFont QString or QVariantList . An Invalid variant returns 0 . This will work for POD and registered built-in Qt types . You would need to use the following method http : qt-project.org doc qt-5.0 qtcore qmetatype.html qRegisterMetaType for register your custom type though . int qRegisterMetaType const char typeName .. . .. . One another thing you could try although it is somewhat superfluous to QVariant is to work with Object s QMetaObject in the following way : .. . .. . const char QMetaObject : : className const .. . .. . Returns the class name . and .. . .. . const QMetaObject QObject : : metaObject const virtual .. . .. . Returns a pointer to the meta-object of this object . .. . A meta-object contains information about a class that inherits QObject e.g . class name superclass name properties signals and slots . Every QObject subclass that contains the Q OBJECT macro will have a meta-object . .. . The meta-object information is required by the signal slot connection mechanism and the property system . The inherits function also makes use of the meta-object . .. . If you have no pointer to an actual object instance but still want to access the meta-object of a class you can use staticMetaObject . Needless to say this will only work for QObjects so not for QString etc . You would need to create QObject subclasses . There is also some QMetaType that you can use for creation but this http : qt-project.org doc qt-5.1 qtcore qmetatype.html typ is a bit different so I am just mentioning here to be complete : .. . .. . int QMetaType : : type const char typeName static .. . .. .

Here http : zeromq.github.io pyzmq serialization.html is a brief python use-case though it s not Qt . Comment : Yes a generic byte socket is able to transmit every kind of data but is maybe not the most simple solution . Are both client and server code written by you or is there an existing server and you have to adapt to how it works Comment : @deviantfan yes both client and server are written by me . .. . Answer : I do not think it is the language data structure type that should be differentiated but it is more about the data you send over . Note that different languages may have different language structures and so on . That is just really low-level details . What is more important is what you send . You could look into the following example how the serialization deserialization works with json format in QtCore . Json is also supported in python quite well by the json module so you would have no issue on the server-side to deserialize it : .. . .. . JSON Save Game Example http : qt-project.org doc qt-5 qtcore-savegame-example.html .. . .. . This is basically the important part that would give you some hint on the client-side . Do not get lost at saving into a file . It is basically writing the raw bytes to the file which you would replace by sending over the network : .. . .. . .. . and then you would do something like this on the server-side again instead of reading from file you would read from the network but that is not a biggie as both are IO . You could use raw protocol to design your own or just use an extending . I would suggest to go with something standard like http tcp udp . Then you would only need to define the json format for your own data and not deal with all the rest like one-way or two-way communication transaction identifier against reply attack timestamp data size and so on . This would allow you to truly concentrate on the important stuff for you . Once you have your own json format defined you could look into the QtNetwork module http : qt-project.org doc qt-5 qtnetwork-index.html to send post get put and delete requests as you wish . You would probably work closely with the QNetworkManager http : qt-project.org doc qt-5 qnetworkaccessmanager.html QNetworkReply http : qt-project.org doc qt-5 qnetworkreply.html classes and so on . Here you can find a simple client implementation in Qt with QtCore s json for a simple pastebin functionality : .. . .. . The JSON is defined in here : .. . .. . http : sayakb.github.io sticky-notes pages api .. . .. .

If you re using a Qt release older than 5.6 ot are willing to compile QtWebKit this might be helpful otherwise this answer is no longer valid . .. . .. . It is hard to tell you exactly what needs to be done as your explanation is incomplete about the use-case . However there are two ways of proceeding . QtWebKit .. . .. .

If you do not need webkit for your sotware and the html data comes in a different way rather than directly from the web for which you would need to use QWebKit then you are better off using the xml parser available in QtCore . It still might be the case even if you do not have any other dependency from QtWebKit that this additional dependency will not cause any issues in your use-case . It is hard to tell based upon your description . For sure this would be less convenient albeit not that much compared to the webkit based solution as that is designed for html .

Ultimately I want to pass a block i.e . array of 384x128 unsigned short values every 100ms from a QThread data-acquisition to a QRunnable data-processing . This means the QRunnable will have 100ms to process the data before the next block arrives . I m still not sure the right way to move the data around . Right now I m using a QVector . In Qt4 I understand implicit sharing to mean that a QVector would not be copied if emitted in a signal until the object is written upon . However in a small test application I made I am not sure I understand exactly what that means . Here is the output of the MWE provided below.. . I am using a dummy QVector with four values and tracking the address of the vector as the thread runs . The data is correct throughout but it seems a copy is made . I am not changing the data at any point in the application.. . just displaying . I ve tried using const QVector unsigned short throughout various iterations of using references etc . The address always changes . Since performance will be important here I m concerned about making copies of the QVector when 384 128 values . Also in another SO question I am struggling with figuring out how to have the QRunnable receive the data that is all left out of this example . But that is important to note here because my idea is to have the QRunnable operate on the reference to the image buffer that lives in the QThread . I just haven t figured out how to do that . The specific questions : .. . .. . -- Why does it appear a copy is made Is this because of multithreading -- Do I have to explicitly use references i.e . image buffer throughout thereby removing QVector entirely Or should I worry about the copies -- What is the right way to pass data from QThread to QRunnable for my situation MWE below to demonstrate the different addresses .

No formal training just a few good books in front of me . main.cpp .. . .. . appwidget.h .. . .. . appwidget.cpp .. . .. . acquire.h .. . .. . acquire.cpp Comment : Your debug code is incorrect . display buffer returns the pointer to the object itself . It s not surprising that it will be different in your case . If you want a pointer to the QVariant s internal array use display buffer.constData . Comment : @PavelStrakhov That was exactly it . The addresses now match in my debug output.. . in the QThread the GUI Thread and in the QRunnable . Excellent . Acquire thread : block acquired : 0x105501010 GUI thread : received signal : 0x105501010 Algorithm thread : 0x105501010 .. . Answer : Copies will be made in this case both because you are passing by value and because signals across thread boundaries are queued . That s fine though because implicit-sharing http : qt-project.org doc qt-5.1 qtcore implicit-sharing.html implicitly-shared means they are shallow copies . There s practically no overhead to copying if both the original and the copy are only used for reading . Unfortunately that s not actually the case in your program . Your forever loop will modify the vector when it loops back around after signal emission . In this example it won t actually change anything in the vector since you re always just assigning 1 2 3 4 but calling the non-const operator is enough to trigger the deep-copy . My conclusion is this : you can be synchronous and share the same buffer between your readers and writers or you can be asynchronous and give a copy of your write buffer to your readers . You cannot be asynchronous and share the same buffer between your readers and your writers . The way you re handling this seems fine for asynchronous processing . Depending on the characteristics of your data generation and data-processing you may or may not find a synchronous solution to be better . The easiest way to make your asynchronous code synchronous is to supply the connection type as Qt : : BlockingQueuedConnection http : qt-project.org doc qt-5.1 qtcore qt.html ConnectionType-enum on connect http : qt-project.org doc qt-5.1 qtcore qobject.html connect . Comment : I d actually prefer to pass-by-reference . I just couldn t get it working . Also I m fine with synchronous processing if I understand synchronous as applied to my application since I ll necessarily need to find a way to finish processing the block of data acquired before the next is available 100ms which seems doable . However I am also not able to figure out how to access what I m calling image buffer even by reference in the QRunnable.. . it lives in QThread . I believe in that instance the signal would just indicate a block is available and pass reference Any advice Comment : Unless AppWidget : : processBlock is going to be modifying the vector there s basically no point in passing by reference rather than by value . But if you absolutely must you can emit a signal with a pointer . You ll need qRegisterMetaType QVector unsigned short QVector unsigned short and emit blockAcquired display buffer .", "Question : I ve a multi-user supporting server which is based on qxmpp library written in Qt and exdended by inheriting QXmppServerExtension .

Comment : Do you have concrete benchmarks how much you would save with it Comment : Actually not : Comment : That is about 220 MB for 16 GB ram . Do you agree that it is negligible unless you have other operations heavily using the memory but in that case this might not be the best place to look for optimization .. . Answer : You can read more about singletons in general why they are considered bad in many cases : .. . .. . What is so bad about Singletons http : stackoverflow.com questions 137975 what-is-so-bad-about-singletons .. . .. . I would personally avoid them in your without the context more . The only reason you bought up so far for singletons rather than passing references or that kind around you would spare some memory for the server service . Based on the discussion it is always better to make sure you have some benchmark in-place when the complexity difference is not obvious . In your special case with additional 216K memory for about 1000 clients you would get about 250 MB additional memory usage . I am rounding this number up a bit just in case . This is in no way comparable to the capacity of your server which seems to be about 16 GB . If you have other memory hungry services those would probably be a more offending place to look into optimization .

Answer : Straight from the Qt documentation http : qt-project.org doc qt-5.0 qtcore qsharedpointer.html we have something like this : .. . .. . You can basically pass your pointer in the same fashion :", "Question : How I can change this code Error : .. . .. . no match for operator operand types are QStringList and QString .. . .. . does not work too : myList is Empty after this . .. . Answer : There is little to no point in using a pointer for a QStringList because this is an implicitly shared class due to the copy-on-write . You can find further details for that below : .. . .. . http : qt-project.org doc qt-5.1 qtcore implicit-sharing.html .. . .. . Which means I would refactor your code to look like this : .. . .. . Note you also had a typo for myList as you seem to have written myLis . That is at least one syntax-error which would lead to compilation error . You could also use the C++11 syntax for this if you have support for that : .. . .. . This will come to handy when you will have more elements to insert without continuous append lines separately . However if you are still interested in doing this for some reason you should consider this : .. . .. . or as a last resort even your line should work if you had not done any other mistakes . This should be the whole code to see if you had done any other mistakes : .. . .. . main.cpp .. . .. . Building something similar .. . .. . Output", "Question : I am new to Qt . I am trying to compile a small code snippet shown below : .. . .. . I am trying to run it through command-line using the following command : .. . .. . However I am getting the following error : .. . .. . I think I need to include the library for QObject but I am not really sure . Any ideas Comment : @Laszlo Papp I tried with your suggestion but its giving wierd errors that too in main.moc file..Is there any library for QObject . Comment : i have created main.pro as you suggested.I got errors like main.moc : 39 : error : Test has not been declared main.moc : 48 : error : Test has not been declared main.moc : 48 : error : non-member function const QMetaObject metaObject cannot have cv-qualifier usr include QtCore qobject.h : In function const QMetaObject metaObject : Comment : @Laszlo Papp : -- Thank you for help . I have tried with clean environment and it works . .. . Answer : You are not using the meta object compiler aka . moc properly . You have a QObject in the source as opposed to the header so instead of including the header into the HEADERS variable for qmake you will need to include the generated moc file in your source code as demonstrated below . Please note that you should add the Q OBJECT macro to your Q OBJECT in general due to the propeties signals and slots that it makes available . This is not strictly necessary to fix this issue but it is better if you are aware of this . main.cpp .. . .. . main.pro .. . .. . Build and Run Comment : HEADERS + main.cpp is missing which instruct qt to run moc tool on this file . Comment : @MarekR : uh you should not mix up headers and sources . Also note that the user was actually using command-line rather than qmake . My answer will work with that too just fine . In general HEADERS was not designed for being the primary interface moc . It just comes as an additional convenience . Do not abuse it . : - Comment : Yes I m aware that this is a hack but it is necessary if you do not have explicit header file for classes where moc tool is needed . Without it your example will not work . Comment : @MarekR : have you actually tried to run it It does work and should work fine . I am afraid you are misunderstanding something ." ] }	[ "yes-answer-long", "yes-answer-short" ]	qtcore	UNK_RELATION

The SCSI standards such as the SAM-5 SCSI Architecture document state that a single SCSI device can have multiple target ports and also multiple logical units . When an initiator sends a request to read-write data to a target it needs to specify both the desired target port and the logical unit number . It seems that either just a port-number or just a logical unit number would be enough to perform the needed multiplexing so a single SCSI interface can provide access to multiple data sources sinks . Do SCSI devices in the real world actually provide multiple target ports and multiple logical units If you can provide an example of a device which has multiple target ports and one which has multiple logical units giving an idea of what ports LUNs are used for in practice that would be very helpful . .. . Answer : Any SAN device provides multiple ports multiple FC ports and or multiple iSCSI ports and also provides multiple LUNs over each of these ports . The exposed LUNs may differ from port to port and the mapping of LUN ID to a volume may differ between the ports so LUN 1 may be volume 23 on port FC1 and LUN 3 on port iSCSI 2 . The port is the physical connection to the world . The LUN is a logical identifier for a volume on a port . The volume is the logical entity that is exposed to the world through the LUN and port mappings . Comment : Thanks So when the SCSI standards refer to a device having multiple target ports that means it will actually have multiple physical connections to the underlying bus network Comment : Yes multiple ports target or initiator mean multiple physical connections to the same fabric . Sometimes you can get multiple logical connections too and they may also be considered different ports . Consider VLANs and different IP Port for iSCSI . Comment : The same logical unit can be exposed to the world via multiple physical ports right It s called a multi-path I O . Please see en.wikipedia.org wiki Multipath I O http : en.wikipedia.org wiki Multipath I O . Do I understand that correctly Comment : Yes .

Answer : In very simple terms ASCQ codes are typically present in Response frames from SCSI target devices . ASCQ code describes additional sense data or typically known as reasons for certain condition occurred in the device .", "Question : I m developing a SCSI target software and I m new to SCSI and I need to return correct sense data to tell initiator that its request didn t go through because data were protected from writing . I m looking at the piece of table from T10.org describing these codes : .. . .. . What s the meaning of these various ASCQ codes I couldn t find any explanations anywhere . Three or four words like PERSISTENT WRITE PROTECT is a max what I can find . I d like to know something like if you have a situation like this then you need to use ASCQ that . .. . Answer : There s a list of these codes here on the T10.org website under the page titled : SCSI ASC ASCQ Assignments http : www.t10.org lists asc-num.htm . This page also describes their purpose titled : SCSI Additional Sense Data http : www.t10.org lists 2asc.htm . SCSI Additional Sense Data takes the form of two value encoded bytes in the sense data typically returned by the REQUEST SENSE command . The additional sense code ASC byte indicates information about the error exception reported in the sense key field . The additional sense code qualifier ASCQ indicates detailed information related to the additional sense code . See the clause describing the REQUEST SENSE command in the SCSI Primary Commands - 4 SPC-4 draft standard or later for more information about sense data . .. . Descriptions of the assigned ASC and ASCQ values and their coded meanings are organized in tables that are sorted numerically based on the ASC ASCQ values or alphabetically based on the text describing the error or exception indicated by the ASC ASCQ pair . An explanation of the ASC ASCQ table format http : www.t10.org lists 8asc-xpl.htm is available if you are unfamiliar with these tables . Additionally I d take a look at the Wikipedia page topic titled : Key Code Qualifier https : en.wikipedia.org wiki Key Code Qualifier which had this to say about these codes . Key Code Qualifier is an error-code returned by a SCSI device . When a SCSI target device returns a check condition in response to a command the initiator usually then issues a SCSI Request Sense command . This process is part of a SCSI protocol called Contingent Allegiance Condition . The target will respond to the Request Sense command with a set of SCSI sense data which includes three fields giving increasing levels of detail about the error : .. . .. . K - sense key - 4 bits byte 2 of Fixed sense data format .. . C - additional sense code ASC - 8 bits byte 12 of Fixed sense data format .. . Q - additional sense code qualifier ASCQ - 8 bits byte 13 of Fixed sense data format .. . .. . The initiator can take action based on just the K field which indicates if the error is minor or major . However all three fields are usually logically combined into a 20 bit field called Key Code Qualifier or KCQ . The specification for the target device will define the list of possible KCQ values . In practice there are many KCQ values which are common between different SCSI device types and different SCSI device vendors . Common values are listed below you should consult your hardware specific documentation as well . Comment : Sorry to say these pages contain only three or four words per ASC ASCQ but I needed more detailed explanation actually I ve copied a part of a page from T10.org to my question . Comment : @AlekseyYakovlev - see update and let me know if the edit helps .", "Question : Does iSCSI introduce any layers other than the TCP-headers themselves on top of the SCSI packet Are there any reference manuals for iSCSI other than the RFC itself I need this information for controlling a RF-receiver over a Paralan iSCSI-to-SCSI-converter . Comment : Related question : stackoverflow.com questions 11211794 http : stackoverflow.com questions 11211794 iscsi-data-transport-packet-overhead .. . Answer : Everything is TCP . iSCSI has its own headers in the PDUs . Authentication and authorization are not required by iSCSI . But the initiator and or target is allowed require authentication . Regarding extra headers over SCSI there is a negotiation process which is not SCSI . Once the negotiation is over iSCSI enters full feature phase . At that point the headers will be specific to SCSI . Since it is just TCP then it should pass directly through to your converter . But you converter will probably need to handle the negotiation process . Once it enters full feature phase you will have to deal with too much to describe here it is not a simple matter of just passing SCSI stuff . Basically a converter would be an iSCSI Target and then the CDB LUN TMF s etc are passed to the SCSI layer . You will have to build up a data interface because your SCSI layer must ask your target layer to receive data transmit data handle TMF s and so on . It is the most complex driver I have ever written . If you need a layer I could supply you one that is system independent . You would then write interface routines for your system .", "Question : null .. . Answer : We are developing an application to manage NVME Devices in Windows 10 . We are not supposed to use our own driver to talk to drives so for sending most of the commands we have to rely on whatever is available from Windows 10 . For commands like Security Receive and Security Send we are using their support of SCSI-NVME Translation in which a SCSI command is sent from the host and is translated to NVME command by the SCSI kernel stack and then sent to the drive . We can see the commands are reaching the drive but the translation is not able to send the correct namespace identifier to the drive in case of the Security Receive command and therefore SCSI is returning a error in sense data as Access denied Invalid LU Identifier . SCSI-NVME translation does not allow setting a namespace identifier field in its CDB . Is there any other way for setting this namespace identifier in the SCSI command that we are sending from the host side Or is this a driver error that its sending incorrect data to the drive Other APIs of Microsoft like Storage Query Property set this namespace ID by themselves and we don t have to set this from user side . If anybody who has worked in similar kind of environment can help us out it will be very helpful . Comment : Just to rephrase the question again I want to know how a namespace Identifier is set via SCSI Command whenever we use SCSI-NVME Translation approach to send Commands to NVME Drive . The SCSI-NVME Translation Spec that I am using does not talk about how NameSpace Identifier is set in CDB . Namespace Identifier is an important field in NVME Command Structure . Comment : Improved formatting and wording . Comment : Ok I will take care next time . Comment : I m not sure why this is downvoted . At least the way it stands now it seems relatively clear - though I don t have an answer for you", "Question : Which case would be considered correct 1 . Doing reads with a Read 16 command no matter if the LBA s are 32 or 64 bit . 2 . If the max LBA is 32-bit then do a Read 10 command and if the max LBA is 64 bit then do a Read 16 command . What are the pros and cons of each choice I know for a Read Capacity command it is correct to run a 10 and if it returns FFFFFFFFh then run a 16 . Why is this the case The Read Capacity 16 command works for both cases and avoids even needing the Read Capacity 10 at all . .. . Answer : Keep in mind that the reason that SCSI has multiple sizes of commands like this is in many cases because SCSI is a very old protocol . It was first standardized in 1986 and was in development for some time before that At the time a large SCSI device would range in the low hundreds of megabytes even a 32-bit LBA was considered excessive at the time . The 64-bit LBA commands simply didn t exist until much later . The question here is really just whether you want to support these old devices . If you do you will need to use Read 10 for reads on small devices as they may not recognize Read 16 . Similarly the use of Read Capacity 10 before Read Capacity 16 is because older devices won t recognize the larger version . Comment : So the older devices are where the issue lies.. . If it is a new device even if the LBA is 32-bit or less the Read 16 and Read Capacity 16 will be fine Comment : In most cases yes that should be correct . Comment : Thanks I will leave the Read 10 in the code . I will use the 16 and make changes as necessary . I am testing pretty new drives for throughput and latency . Is there any difference you would expect as far as that goes Comment : I would be very surprised if there was a difference in performance between the 10 and 16-byte READ CDBs . I think you d be fine just to use READ 16 exclusively . Comment : @gubblebozer Not all devices especially older devices support READ 16 . You ll get better compatibility results if you avoid it when not necessary .", "Question : Is it possible for multiple computers to connect to the same target at the same time using the same initiator IQN Thank you . .. . Answer : It s not a good idea . From RFC 3720 http : www.ietf.org rfc rfc3720.txt : .. . .. . .. . a iSCSI names are globally unique . No two initiators or targets .. . can have the same name . .. . .. . You may find that duplicate IQN s may work on a given target . But even then you must ensure that the iSCSI session ID s can not overlap or the target may get very confused . The combination of IQN iSCSI session ID and target form the I T nexus that the target will use to keep track of things . Again from RFC 3720 : .. . .. . .. . c I T nexus - a relationship between a SCSI Initiator Port and a .. . SCSI Target Port according to SAM2 . For iSCSI this .. . relationship is a session defined as a relationship between .. . an iSCSI Initiator s end of the session SCSI Initiator Port .. . and the iSCSI Target s Portal Group . The I T nexus can be .. . identified by the conjunction of the SCSI port names or by the .. . iSCSI session identifier SSID . iSCSI defines the I T nexus .. . identifier to be the tuple iSCSI Initiator Name + i + ISID .. . iSCSI Target Name + t + Portal Group Tag . .. . .. . This nexus object must be unique .", "Question : The SCSI reference manual defines two types of sense data formats - fixed and variable descriptor-based ones chapter 2.4 . The Control Mode Page 0Ah 4.3.8 which is supposed to be returned as a response to the MODE SENSE SCSI command contains a D SENSE bit which is defined as : .. . .. . D SENSE DESCRIPTOR FORMAT SENSE DATA bit .. . .. . 0 A descriptor format sense data D SENSE bit set to zero specifies that the device server shall return the fixed format sense data when returning sense data in the same I T L Q nexus transaction as a CHECK CONDITION status . 1 A D SENSE bit set to one specifies that the device server shall return descriptor format sense data when returning sense data in the same I T L Q nexus transaction as a CHECK CONDITION status except as defined in 2.4.1 . My question is about this bit interpretation on the SCSI target side - is the target server obligated to return sense data in the descriptor format if this bit is 1 Or it s just a possibility to return this data in any format it wants The first byte of the sense data can be used to determine its format so the SCSI initiator doesn t actually need the D SENSE bit value to decide how to decode the received sense data . I m asking this question cause I m working on some piece of software which is supposed to simulate a SCSI target so I need to digest multiple SCSI documents to make it right . .. . Answer : If the SCSI target implements the ability to set this bit it must be able to return either of the sense formats . The SCSI target may choose to only provide this bit for reading and not writing and then it dictates what format it returns . Please also notice that to be properly SCSI compliant you also need to provide the mode page in a mask mode that shows which bits of a mode page are settable . Comment : Mode page in a mask mode - you mean bits settable by MODE SELECT right I can see that the sense data should be returned by target as a response to the REQUEST SENSE as well . Fortunately this command has two variants - for fixed sense and descriptor sense . So if D SENSE is not set then the target should return the error in CDB right Comment : If the D SENSE is not set you should return sense buffers in fixed sense format . You can prevent setting this bit at all so you only need to implement the fixed sense format . Comment : I actually need to implement sense data in the descriptor format as well because this format is needed to report such info as formatting in progress as a response to the REQUEST SENSE . So I worry about how to do that without or with minimal disrupting all the other sense data messages which my target is supposed to generate . Comment : You can report format in progress and progress level in fixed sense too . You can look at my libscsicmd library that has full parsing of scsi sense . Comment : Thank you for the reference to your library So - I can report the progress level in bytes 15-17 of the fixed sense data right", "Question : I try to issue a scsi read 10 http : en.wikipedia.org wiki SCSI Read Commands Read .2810.29 and write 10 http : en.wikipedia.org wiki SCSI Write Commands Write .2810.29 to a SSD .

Right But running them again changes nothing . You could now assume that the memory I use has still the data from previous funcions but I get the same result even though I run memset Readbuff 0 sizeof Readbuff before the sys read happens . I assumed that the LBA I try to write is maybe forbidden to write and I read the cache . But interating over LBA Adresses from 0x00-0xFF changes nothing - That means I read the same data Abcdefg . Do you know an example implementation of scsi read or writes with the scsi generic interface .. . Answer : In SCSI the units of the LBA and the transfer length are in blocks sometimes called sectors . This is almost always 512 bytes . So you can t read or write just 32 bytes . At a minimum you ll have to do 512 bytes one block . This one point is most of what you need to fix . Your transfer length is zero in your scsi write implementation so it s not actually going to write any data . You should use different buffers for the CDB and the write read data . I suspect that confusion about these buffers is leading your implementation to write past the end of one of your statically-allocated arrays and over your ReadBuffer . Run it under valgrind http : valgrind.org docs manual quick-start.html and see what shows up . And lastly a lot could go wrong in whatever is in handle scsi cmd . It can be tricky to set up the data transfer.. . in particular make sure you re straight on which way the data is going in the I O header s dxfer direction : SG DXFER TO DEV for write SG DXFER FROM DEV for read .

I m fiddling around with issuing SCSI commands and the information would be appreciated . .. . Answer : When the fopen function is invoked in C it issues a system call to the kernel . Not exactly . fopen 3 is a library function that eventually calls open 2 a system call . I would like to know which kernel modules are responsible in processing the system call and returning the file-descriptor to the calling program . None . In Linux the system calls are all handled by the core kernel not a module . See fs open.c . Are these kernel modules also responsible in handling read and write operations If not which modules are responsible . Same deal . See fs read write.c . At the point the kernel is given a path to open it will first determine the mount point where the file you re requesting lives . A filesystem will be mounted at that mount point and that filesystem is implemented is implemented in a module . Filesystems work on top of block devices . And those block devices e.g . SCSI IDE are also implemented in modules . I m fiddling around with issuing SCSI commands and the information would be appreciated .

Comment : @Daedalus modules will be involved during the processing of the open read-write syscalls though .

In looking at CUPS you ve picked a good place to look for what you re trying to do . .. . Answer : I really wish I could accept two answers because I don t think I could have done this without all of @Kurt Pfeifle s help for Mac specifics and just understanding printer drivers and locations of files . But here s what I did : .. . .. . .. . .. . 1 . Download the source code from codepoet cups-pdf-for-mac-os-x https : bitbucket.org codepoet cups-pdf-for-mac-os-x overview . For non-macs you can look at http : www.cups-pdf.de The readme is greatly detailed and if you read all of the instructions carefully it will work however I had a little trouble getting all the pieces so I will outline exactly what I did in the hopes of saving someone else some trouble . For this the directory with the source code is called cups-pdfdownloaddir . 2 . Compile cups-pdf.c contained in the src folder as the readme specifies : .. . .. . gcc -09 -s -lcups -o cups-pdf cups-pdf.c .. . .. . There may be a warning : ld : warning : option -s is obsolete and being ignored but this posed no issue for me . Copy the binary into usr libexec cups backend . You will likely have to the sudo command which will prompt you for your password . For example : .. . .. . sudo cp cups-pdfdownloaddir src cups-pdf usr libexec cups backend .. . .. . Also don t forget to change the permissions on this file--it needs root permissions 700 which can be changed with the following after moving cupd-pdf into the backend directory : .. . .. . sudo chmod 700 usr libexec cups backend cups-pdf .. . .. . 3 . Edit the file contained in cups-pdfdownloaddir extra cups-pdf.conf . Under the PDF Conversion Settings header find a line under the GhostScript that reads GhostScript usr bin gs . I did not uncomment it in case I needed it but simply added beneath it the line Ghostscript usr bin pstopdf . There should be no pre-cursor for any of these modifications .. . .. . Find the line under GSCall that reads GSCall s -q -dCompatibilityLevel s -dNOPAUSE -dBATCH -dSAFER -sDEVICE pdfwrite -sOutputFile s -dAutoRotatePage s PageByPage -dAutoFilterColorImages false -dColorImageFilter FlateEncode -dPDFSETTINGS prepress -c .setpdfwrite -f s Again without uncommenting this under this I added the line GSCall s s -o s s .. . .. . Find the line under PDFVer that reads PDFVer 1.4 and change it to PDFVer no spaces or following characters . Now save and exit editing before copying this file to etc cups with the following command .. . .. . sudo cp cups-pdfdownloaddir extra cups-pdf.conf etc cups .. . .. . Be careful of editing in a text-editor because newlines in UNIX and Mac environments are different and can potentially ruin scripts . You can always use a perl command to remove them but I m paranoid and prefer not to deal with it in the first place . .. . .. . 4 . You should now be able to open a program e.g . Word Excel .. . and select File Print and find an available printer called CUPS-PDF . Print to this printer and you should find your pdfs in var spool cups-pdf yourusername by default . .. . .. . Also I figured this might be helpful because it helped me : if something gets screwed up in following these directions and you need to start over get rid of it in order to remove the driver you need to 1 remove the cups-pdf backend from usr libexec cups backend 2 remove the cups-pdf.conf from etc cups 3 Go into System Preferences Print Fax and delete the CUPS-PDF printer . .. . .. . This is how I successfully set up a pdf backend filter for myself however there are more details and other information on customization contained in the readme file . Hope this helps someone else Comment : I thought your ultimate goal was to print whatever the user s document is to a PDF and add some headers before sending it off to a device .. . . So how did you solve the last part My answer only covered the first part -- I didn t know from your question what the detailed requirements for the second part were .

In looking at CUPS you ve picked a good place to look for what you re trying to do . .. . Answer : The way to go is this : .. . .. . Set up a print queue with any driver you like . But I recommend to use a PostScript driver PPD . A PostScript PPD is one which does not contain any cupsFilter : .. . line . : .. . .. . Initially use the educational CUPS backend named 2dir . That one can be copied from this website : KDE Printing Developer Tools Wiki http : community.kde.org Printing Developer Tools .272dir.27 CUPS backend script .28Bash code.29 . Make sure when copying that you get the line endings right Unix-like . .. . .. . Commandline to set up the initial queue : .. . .. . lpadmin .. . -p pdfqueue .. . -v 2dir : tmp pdfqueue .. . -E .. . -P path to postscript-printer.ppd .. . .. . .. . The 2dir backend now will write all output to directory tmp pdfqueue and it will use a uniq name for each job . Each result should for now be a PostScript file . with none of the modifications you want yet . Locate the PPD used by this queue in etc cups ppd its name should be pdfqueue.ppd . Add the following line best near the top of the PPD : .. . .. . cupsFilter : application pdf 0 - .. . .. . Make sure the cupsFilter starts at the very beginning of the line . This line tells cupsd to auto-setup a filtering chain that produces PDF and then call the last filter named - before it sends the file via a backend to a printer . That - filter is a special one : it does nothing it is a passthrough filter . Re-start the CUPS scheduler : .. . .. . sudo launchctl unload System Library LaunchDaemons org.cups.cupsd.plist .. . sudo launchctl load System Library LaunchDaemons org.cups.cupsd.plist .. . .. . From now on your pdfqueue will cause each job printed to it to end up as PDF in tmp pdfqueue .pdf . Study the 2dir backend script . It s simple Bash and reasonably well commented . Modify the 2dir in a way that adds your desired modifications to your PDF before saving on the result in tmp pdfqueue .pdf .. . .. . .. . .. . .. . Update : Looks like I forgot 2 quotes in my originally prescribed cupsFilter : .. . line above . Sorry Comment : This sounds like exactly what I need Thanks for taking the time to write this all out . However please bear with me as my unfamiliarity with CUPS and printer terms makes me ask minute step-by-step questions that you might have already answered . The link-to the KDE Printing Developer Tools Wiki specifies that 2dir should be saved in usr lib cups backend however I don t seem to have a cups directory in usr lib . Have I missed something Also the last flag to set up the initial queue I assume I am supposed to replace the path but with what exactly Comment : @Katie : Sorry I had Linux in mind with that path . On Mac OS X you ll have to use usr libex cups backend . The last -P flagged path argument you can replace with User katie postscript-printer.ppd .. . but of course you should put a real PostScript printer PPD there with that name . Comment : Okay I got that sorted out--pdfqueue is a printer option . I believe I followed the other instructions however when I try to print I get a dialog that says This printer has been paused . Do you want it to resume printing With options to Cancel Add to Queue or Resume . Hitting either Add to Queue or Resume adds the print job so I can see it in the pdfqueue printer GUI that popped up but does not seem to respond to resume and just sits there . tmp pdfqueue doesn t seem to exist so I m not quite sure where this file is going . Any suggestions Comment : @Katie : Add a line saying LogLevel debug in your etc cups cupsd.conf file and re-start CUPS sudo launchctl .. . commands above . Comment : @Katie : Oh it s possibly my mistake -- the cupsFilter : .. . line I prescribed to you above is missing a pair of quotes . Add them please restart CUPS and try again .

If I run this through CUPS xhtmltopdf filter to simulate printing then several flaws appear . The header looks correct on the first page but does not appear on any subsequent pages like they would from Chrome s own print dialog . This proves that it s styling some things from the media print selector otherwise I d just see plain inputs .

When I ask Google for that it shows me many tutorials and documentations - but all for end users no programming examples . So does anybody know a good programmers HOWTO tutorial that shows printing under Linux Thanks .. . Answer : CUPS doesn t have its own document description API . It doesn t need one : formats like PostScript PDF and JPEG are first-class citizens of CUPS . You use whatever program or API you like to create a such a file and you then send it to CUPS with lpr or with the CUPS API and CUPS will transform it to the appropriate internal format and send it to the printer . So for your case you might use a vector-graphics library like Cairo http : www.cairographics.org manual to author PostScript and then you send that off to CUPS for printing . Here s a simple C example : .. . .. . Strictly you don t need that temporary file : the CUPS API allows you to construct a stream and you can emit the page data into that but a file is handy for debugging .", "Question : Our C++ application is using cups to print out a postscript file generated by XRT XrtTblVaDrawPS command . But when I print 2 copies and set the cups collate option the file is not printed out as collated . .. . Answer : Our project is using XRT motif library to generate a postscript file from a table layout using motif . The postscript file generated by XrtTblVaDrawPS was printed using cups but during testing the cups Collate option appeared not to work when we where printing more then 1 copy . Web searches did not return any reason why the ps file was not collating but after a lot of experimentation we found out why cups was not working as expected . The XrtTblVaDrawPS call generating the ps file and one of the option used was XRTTBL PS NUM COPIES 2 to set how many copies the postscript file would print out . In our cups class we were doing a cupsAddOption copies 2 . . and cupsAddOption Collate True . . commands see examples below . It turns out the the cups copies command was killing the Collating if it set to 2 . Like the orientation postscript cups conflict you need to set the cups copies value to 1 to get the collation to work . The postscript file already knows its going to print out for example 2 copies . If you don t want it to be collated then set cups copies to 2 number . If you are generating a postscript file some other way this problem might not be happening to you but it is if you are using the XrtTblVaDrawPS call . pgs XrtTblVaDrawPS myTable fp XRTTBL PS NUM COPIES num set to 2 XRTTBL PS CELL RANGE rng XRTTBL PS COLOR clr XRTTBL PS ORIENTATION ornt XRTTBL PS SCALE FIT TO PAGE HEIGHT XRTTBL PS SHOW ROW LABELS XRTTBL PS ALL XRTTBL PS SHOW FROZEN ROWS XRTTBL PS ALL XRTTBL PS SHOW COL LABELS XRTTBL PS ALL XRTTBL PS SHOW FROZEN COLS XRTTBL PS ALL XRTTBL PS PAPERSIZE WIDTH media sz.width XRTTBL PS PAPERSIZE HEIGHT media sz.length XRTTBL PS MARGIN LEFT 1.00 XRTTBL PS MARGIN RIGHT 1.00 XRTTBL PS MARGIN TOP 0.75 XRTTBL PS MARGIN BOTTOM 0.75 XRTTBL PS HEADER FONT Adobe 10 XRTTBL PS HEADER hdr XRTTBL PS HEADER MARGIN 0.55 XRTTBL PS FOOTER FONT Adobe 10 XRTTBL PS FOOTER Page XRTTBL PS FOOTER MARGIN 0.25 NULL .. . .. . myNumOptions cupsAddOption Collate True myNumOptions myOptions myNumOptions cupsAddOption copies oss.str .c str myNumOptions myOptions .. . .. . oss.str .c str is 2 and collate fails and I get 1-1-2-2 oss.str .c str is 1 and collate works and I get 1-2-1-2 oss.str .c str is 2 and cups Collate set to False I get 1-1-2-2 as expected", "Question : null .. .

Comment : Thanks That was the problem . . When I did this it caused a Bad Request error which I solved by adding ServerAlias to etc cups cupsd.conf and everything worked like a charm . Thanks again .", "Question : null .. . Answer : We are using the Xerox Linux drivers to print on our multifunction printer . Basically when you print the driver opens a pop-up window to let you choose different printing options then calls lp for printing . This works pretty well on single user computer but when many users are logged-in at the same time on the machine the driver doesn t know which DISPLAY to use : 0 : 1 : 2 etc . . Thus when printing the pop-up appears on : 0 even though a user can be on : 1 or : 2 . When it comes to printing the printing subsystem runs as an OS user lp on Debian . This OS user doesn t have an X session and thus no DISPLAY value . Since DISPLAY isn t set the driver assumes : 0 being the typical single-user client display . Therefore when using the User Switching mechanism CUPS does not forward the requesting user s DISPLAY so the driver assumes the : 0 display if not specified . This causes user2 s driver interface to be sent to user1 s display . Here is a snippet of the log when printing .

I am not looking for a full walkthrough solution here if you have one I won t spit on it though but for some hints on what I should try to do . I ve thought of : .. . .. . 1 - Disabling user switching in GNOME3 https : askubuntu.com questions 153930 how-to-permanently-disable-user-switching-in-gnome-3 but this is a last resort solution since it is quite useful for users .. . .. . 2 - Forcing CUPS to call lp with the -o DISPLAY option grepped from the user that called the process . If this were feasible it would be quite nice . 3 - Force GNOME3 to show currently used user on : 0 and move idle ones to other displays . I have no idea how 2 could be done and I m not sure if 3 is feasible . I ve already tweaked GNOME3 to log off users that are idle more than 30min but it s not enough to solve the problem . Any help Comment : File a support request with Xerox for their printer driver to not be crazy Comment : Heh this was their response : Development recommends the customer speak to the CUPS support team and see if there is a similar command that can be incorporated into CUPS for this is a way to incorporate the command already provided .

What is wrong i am running ubuntu linux 9.04 .. . Answer : There is no way to do anything else but speculation if you don t provide a detailed record of what exactly your lpadmin command was or what manipulation of the printers.conf file you made . Also note that direct editing of printers.conf is not recommended unless you do it while cupsd is stopped . CUPS quotas do work for me . However the last job crossing the quota threshold will always start printing since CUPS does know about its number of pages only after starting to process the jobfile not beforehand.. . Comment : so if someone tries to print 100 pages in one job and the quota allows 4 more pages cups will simply allow them to do it Comment : so if someone tries to print 100 pages in one job and the quota allows 4 more pages cups will simply allow them to do it -- Yes .

Answer : I have printers at my school on what I assume is a LAN I can print and access config site only while connected to the same network . The way it works now is that a students send a print job to an industrial plotter . Dedicated staff working the plotters then have to actually release the job from the printer s job-queue webpage after verifying the job is oriented correctly printer s width is 32 etc . I want to centralize printing onto one server instead of students sending prints from their os I want to have them upload the file to my server through a website and the server takes care of the rest from verifying dimensions of the PDF to releasing the print in the plotter . I plan to use a Raspberry Pi kept on 24 7 connected to the network to run my python script so that the printers are accessible to it . I have heard of the CUPS API which has a python wrapper that suits my Flask app needs . At the same time unix systems have the lp and lpr commands to interact with network and local printers . What I ve been doing is making subprocess.Popen calls to execute lp and it does indeed send to the chosen plotter but that leaves actually releasing the job from the queue for the printer to print . My solution is to automate selenium to open the plotter s job-queue page and find the elements I need to analyze and or click so that the job actually starts printing . I was wondering if the actual releasing of the job could be done with the CUPS API Or even with lp lpr", "Question : I have been trying to use a thermal-printer Bixolon SRP-F310 and print some text using JAVA s PrintService .

Comment : Yes I had done that already no luck . .. . Answer : Do the following steps and Hopefully your problem will be solved . 1 . Check the IP of your printer if it s same which you are hitting through CUPs then fine otherwise you have to reset the IP . 2 . Reset IP : Press the feed button of your thermal-printer for 2-3 min a long print receipt will print with detail info about the printer . Now just attache your printer with LAN cable to your PC and open the printer settings . Here you can reset the printer IP according to the manual of that particulate printer . After setting the IP now try again from the server to hit on that thermal-printer with new IP . If your CUPS is installed properly then it will work and otherwise you have to check the CUPS . Check all these things and let me know is that works or any error message . Comment : Printer works fine when I try to print through CUPS Web Interface .

What is the minimal code and dependencies I could get away with to do that . Using LPR or libcups gives me lot of cross-plattform dependencies . So my first approach was to implement a minimal subset of IPP the protocol used by cups and many modern printers since it s only extended HTTP . But unfortuntely a IPP client is a lot more code than a few lines and so far I found no IPP client implementation meant for just printing and not managing a printserver .

Answer : From your comments it looks like you are already familiar with the best practice for dealing with this : version a configuration template and keep the actual configuration unversioned . But since you aren t happy with that solution here is another one you can try : .. . .. . Mercurial 2.1 introduced the concept of Phases http : mercurial.selenic.com wiki Phases . The phase is changeset metadata marking it as secret draft or public . Normally this metadata is used and manipulated automatically by mercurial and its extensions without the user needing to be aware of it . However if you made a changeset 1234 which you never want to push to other repositories you can enforce this by manually marking it as secret like this : .. . .. . If you then try to push to another repository it will be ignored with this warning : .. . .. . This solution allows you to .. . .. . 1 . version the local configuration changes .. . 2 . prevent those changes from being pushed accidentally .. . 3 . merge your local changes with other changes which you pull in .. . .. . The big downside is of course that you cannot push changes which you made on top of this secret changeset because that would push the secret changeset along . You ll have to rebase any such changes before you can push them . Comment : Thanks I ve got hg 2.0.2 now but this looks promising and it is simpler than using patches . But I see that having a secret revision will force me to branch commit and rebase for every single commit from then on . Could you suggest the right graft transplant rebase procedure There seem to be so many options . Comment : @alexis : I feel graft would be the best choice since that s a core command . But to be honest I personally prefer the solution with versioned templates and unversioned config files so I have no experience with all the ugly details of the approach I describe here . Comment : Thanks If that s considered Best Practice I ll think about it more carefully .

Answer : 1 Mercurial have follow-up to comments selective string-based commit - see Record Extension .. . .. . 2 strike Local changes inside versioned public files can be easy received with MQ Extension I do it for site-configs all time strike . Your headache with MQ .. . .. . Every time I want to commit a regular changeset to the local repo I need to pop all patches commit the modifications and re-apply the patches . When I m ready to push to the master repo I must again pop the patches push and re-apply them . is a result-of not polished workflow and some misinterpretation . If you want commit without MQ-patches - don t do it by hand . Add alias for commit which qop -all + commit and use this new command only . And when you push you may don t worry about MQ-state - you push changesets from repo not WC state . Local repo can also be protected without alias by pre-commit hook checking content . 3 You can try LocalBranches extension where your local changes stored inside local branches and merge branches on changes - I found this way more troublesome compared to MQ Comment : Right the RecordExtension enables smaller-than-file granularity for commits . But I was referring to flagging revsets as share or don t share which is what hg phases do as @Wim points out . Could you please elaborate on how you use mq to hold local changes I ve tried but the only way I found seems very clunky . Comment : @alexis - well I use almost like you . 1 - I use THG 2 - I have vanilla file in repo 3 - Two indepenent patches in MQ - one per site 4 - work all time with both patches popped 5 - on deploy by hand for now : push --move first copy patched file from WC pop push --move second copy file pop . It s good for 2 sites on increased amount I ll think maybe about parametrized alias for qpush --move + copy Comment : Every time I want to commit a regular changeset to the local repo I need to pop all patches -- I m sorry but if you wanna commit something then your working dir is dirty -- pop on a dirty working dir is not allowed nasty use refresh warning appears . What did I miss Comment : @springy76 - Why you asked me I quoted OP and clearly I hope show it in my answer", "Question : I ve recently started working with MQ as I like the idea of working on isolated patches and committing without affecting the repo until the changeset is refined enough . Before that I used to work with Mercurial s shelves extension but found it a bit unstable .

Start working on a new patch : .. . .. . 2 . Get a new feature bug to work on : .. . .. . 3 . At this point I d like to get back to working on bugfix and put aside the feature work .

I should note that the files I work on are completely separate as well though they can sometimes be the same . Am I missing something here Should I be using hg qqueue for this Thanks . .. . Answer : You could use guards http : hgbook.red-bean.com read advanced-uses-of-mercurial-queues.html . They allow you to maintain an ordering of patches without rearranging your series file and selectively apply only a subset of patches still in a stack-ordered fashion . An example in your case would be : .. . .. . At this point you re in a situation where patch feature comes before bugfix in your stack . Now you can use guards to select one or the other and switch between the two : .. . .. . If you want to work on feature : .. . .. . If you want to work on bugfix : .. . .. . Note that since you selected the positive guard bugfixguard MQ leap-frogged over feature because it s positive guard was different than the one selected and applied the patch bugfix instead which did match the selected guard . Some useful tools when working with guards are hg qseries -v which will display a G instead of the usual U for a guarded unapplied patch and hg qselect -l which will display the guards associated with each patch .", "Question : I am developing a web database that is already in use for about a dozen separate installations most of which I also manage .

What I was doing under svn was to maintain templates in a directory which are copied to unversioned files and modified . This means that changes to the templates e.g . new defaults never make it to the installed copies . A DVCS should be able to do more . .. . Answer : Having followed up on the suggestions here I came to the conclusion that named branches plus rebase provide a simple and reliable solution . I ve been using the following method for some time now and it works very well . Basically the history around the local changes is separated into named branches which can be easily rearranged with rebase . I use a branch local for configuration information . When all my repos support Phases I ll mark the local branch secret but the method works without it . local depends on default but default does not depend on local so it can be pushed independently with hg push -r default . Here s how it works : .. . .. . 1 . Suppose the main line of development is in the default branch . You could have more branches this is for concreteness . There is a master stable repo that does not contain passwords etc . : .. . .. . ---o--o--o default .. . .. . .. . 2 . In each deployed non-development clone I create a branch local and commit all local state to it . ...o--o--o default .. . .. . L--L local .. . .. . .. . 3 . Updates from upstream will always be in default . Whenever I pull updates I merge them into local n is a sequence of new updates : .. . .. . ...o--o--o--n--n default .. . .. . L--L--N local .. . .. . .. . The local branch tracks the evolution of default and I can still return to old configurations if something goes wrong . 4 . On the development server I start with the same set-up : a local branch with config settings as above . This will never be pushed . But at the tip of local I create a third branch dev . This is where new development happens . ...o--o default .. . .. . L--L local .. . .. . d--d--d dev .. . .. . .. . 5 . When I am ready to publish some features to the main repository I first rebase the entire dev branch onto the tip of default : .. . .. . hg rebase --source min branch dev --dest default --detach .. . .. . .. . The previous tree becomes : .. . .. . ...o--o--d--d--d default .. . .. . L--L local .. . .. . .. . The rebased changesets now belong to branch default . With feature branches add --keepbranches to the rebase command to retain the branch name . The new features no longer have any ancestors in local and I can publish them with push -r default without dragging along the local revisions . Never merge from local into default only the other way around . If you forget to say -r default when pushing no problem : Your push gets rejected since it would add a new head . 6 . On the development server I merge the rebased revs into local as-if I d just pulled them : .. . .. . ...o--o--d--d--d default .. . .. . L--L-----N local .. . .. . .. . 7 . I can now create a new dev branch on top of local and continue development . This has the benefits that I can develop on a version-controlled configured setup that I don t need to mess with patches that previous configuration stages remain in the history if my webserver stops working after an update I can update back to a configured version and that I only rebase once when I m ready to publish changes . The rebasing and subsequent merge might lead to conflicts if a revision conflicts with local configuration changes but if that s going to happen it s better if they occur when merge facilities can help resolve them . Comment : Are you still following this procedure I m quite conflicted on how to manage configuration-files across environment branches template don t feel right as one then has a number of unversioned configuration-files patches or the ExcludeExtension feel like a total cludge and rebasing feels like a lot of work . A good answer is tougher than I expected . Comment : Yes I am . I m managing almost a dozen clones of my project each with local customizations as well as its connection settings and I m very happy with this set-up . Instead of step 3 and 6 I used to rebase the local branch so it s always branching off the tip of default . That gives cleaner-looking history but it made it impossible to simply revert to an older configured state when something goes wrong . So the clones repos contain the history of the configured versions as well as that of the distributed software .", "Question : Recently Mercurial added phases . Is this possible to restrict mq to work only on phase draft It should show a warning when I try to strip public changeset . .. . Answer : No as of Mercurial 2.1 this hasn t been implemented yet . That release provided the basis for the phase concept but as you ve seen not all commands have been updated to take phases into account . We ll work on that for the next releases . Comment : Well.. . I m happy to hear that in future releases of Mercurial extensions will be aware of phases . : Comment : Some mq commands are aware of phases . If you try use hg qimport on a revision with a public phase it will fail with the message abort : revision X is not mutable . Also the rebase extension fails if you try to rebase a public changeset . Both direct you to hg help phases for more info . Comment : @SteveKaye : good points we did manage to make some commands phase-aware . The support will increase gradually in the next releases just like we now have support for revsets almost everywhere .", "Question : This is a best practice question and I expect the answer to be it depends . I just hope to learn more real world scenarios and workflows . First of all I m talking about different changes for the same project so no subrepo please . Let s say you have your code base in an hg repository . You start to work on a complicated new feature A then a complicated bug B is reported by your trusted tester you have testers right . It s trivial if the fix for B depends on A . You simlply ci A then ci B . My question is what to do when they are independent or at least it seems now . I can think of the following ways : .. . .. . 1 . Use a separate clone for B . 2 . Use anonymous or named branches or bookmarks in the same repository . 3 . Use MQ with B patch on top of A . 4 . Use branched MQ I ll explain later . 5 . Use multiple MQ since 1.6 .. . .. . 1 and 2 are covered by an excellent blog http : stevelosh.com blog 2009 08 a-guide-to-branching-in-mercurial by @Steve Losh linked from a slightly related question http : stackoverflow.com questions 1405604 managing-release-branches-in-mercurial . The one huge advantage of 1 over the other choices is that it doesn t require any rebuild when you switch from working on one thing to the other because the files are physically separated and independent . So it s really the only choice if for example A and or B touches a header file that defines a tri-state boolean and is included by thousands of C files don t tell me you haven t seen such a legacy code base . 3 is probably the easiest in terms of setup and overhead and you can flip the order of A and B if B is a small and or urgent fix . However it can get tricky if A and B touches the same file s . It s easy to fix patch hunks that failed to apply if A and B changes are orthogonal within the same file s but conceptually it s still a bit risky . 4 can make you dizzy but it s the most powerful and flexible and scalable way . I default hg qinit with -c since I want to mark work-in-progress patches and push pull them but it does take a conceptual leap to realize that you can branch in MQ repo too . Here are the steps mq hg --mq : .. . .. . 1 . hg qnew bugA make changes for A hg qref .. . 2 . mq branch branchA hg qci .. . 3 . hg qpop mq up -rtip .. . 4 . hg qnew bugB make changes for B hg qref .. . 5 . mq branch branchB hg qci .. . 6 . To work on A again : hg qpop mq up branchA hg qpush .. . .. . It seems crazy to take so many steps and whenever you need to switch work you must hg qci hg qpop mq up branch hg qpush . But consider this : you have several named release branches in the same repository and you need to work on several projects and bug fixes at the same time for all of them you d better get guaranteed bonus for this kind of work . You d get lost very soon with the other approaches . Now my fellow hg lovers are there other better alternatives .. . .. . UPDATE qqueue almost makes 4 obsolete . See Steve Losh s elegant description here http : stevelosh.com blog 2010 08 a-git-users-guide-to-mercurial-queues multiple-patch-queues . Comment : As if it s not obvious I m asking for an hg-based approach . But if you can give me a single command from another SCM that works in all cases I m ditching hg . Consider it a challenge git aficionados . Comment : I think you need to specify your problem a little better . Why doesn t this work for all cases : fix bug A commit its patch fix bug B commit its patch Comment : Sorry that I rambled a bit Spolsky-ishly . I mentioned one simple case : if B is a small and or urgent fix . A more realistic situation is that A and B are both long projects that takes a lot of commits and iterations . Also if you have a code-review process like my company does you may have finished A and sent it out for review and you can t sit there twiddling your thumbs waiting for the reviewers so you have to go pick up B in the meanwhile . But then the reviewer may blast your code and you have to make changes to please him her . So there can be countless project switches along the way .

Comment : Well it seems like you are just working alone on this project . If you were working in a team you would probably never even ask this question because parallel development would be something you simply do and take the relative cost of it in stride with it . While doing parallel development the best practice is clearly a named branch for every feature and subsequent merge down to trunk when the feature or bug is done with as many merge ups from the trunk to your branch as necessary to stay current on other changes during the development of this feature . Not merging down before you run tests . .. . Answer : It seems like there s no more or better choices than the ones I listed in the question . So here they are again . 1 . Use one clone per project . Pros : total separation thus no rebuild when switching projects . Cons : toolchain needs to switch between two clones . 2 . Use anonymous or named branches or bookmarks in the same repository . Pros : standard hg or any DVCS practice clean and clear . Cons : must commit before switching and rebuild after . 3 . Use MQ with one patch or multiple consecutive patches per project . Pros : simple and easy . Cons : must qrefresh before switching and rebuild after tricky and risky if projects are not orthogonal . 4 . Use one MQ branch or qqueue in 1.6+ per project . Pros : ultra flexible and scalable for the number of concurrent projects .. . Cons : must qrefresh and qcommit before switching and rebuild after feels complicated . Like always there s no silver bullet so pick and choose the one right for the job . .. . .. . UPDATE For anyone who s in love with MQ using MQ on top of regular branches 2 + 3 is probably the most common and preferable practice .

Answer : No you aren t missing anything . The mq extension does make a pretty strong assumption that patch queues are linear . If you re going to be creating multi-patch features fixes then qqueue would work But if your features fixes are just single patches and you want to be able to apply one with out applying the others it might be easier to just re-arrange .hg patches series which stores the order that patches will be applied .

Comment : Well it seems like you are just working alone on this project . If you were working in a team you would probably never even ask this question because parallel development would be something you simply do and take the relative cost of it in stride with it . While doing parallel development the best practice is clearly a named branch for every feature and subsequent merge down to trunk when the feature or bug is done with as many merge ups from the trunk to your branch as necessary to stay current on other changes during the development of this feature . Not merging down before you run tests . .. . Answer : So the question is at the point when you are told to stop working on feature A and begin independent feature B what alternative options are there for : How to manage concurrent development with mercurial Let s look at the problem with concurrency removed the same way you write threaded code- define a simple work flow for solving any problem given to you and apply it to each problem . Mercurial will join the work once it s done . So programmer A will work on feature A . Programmer B will work on feature B . Both just happen to be you . If only we had multi-core brains : .. . .. . I would always use named branches because that lets Mercurial do its job : to keep your project history and to remember why you made which changes in what order to your source code . I agree with Brandon s sentiment but I wonder if he overlooked that feature A has not been tested In the worst case the code compiles and passes unit tests but some methods implement the previous requirements and some methods implement the new ones . A diff against the previous check-in is the tool I would use to help me get back on track with feature A . Is your code for feature A at a point when you would normally check it in Switching from feature A to working on feature B is not a reason to commit code to the head or to a branch . Only check in code that compiles and passes your tests . My reason is if programmer C needs to begin feature C a fresh checkout of this branch is no longer the best place to start . Keeping your branch heads healthy means you can respond quickly with more reliable bug fixes . The goal is to have your tested and verified code running so you want all your code to end up merged into the head of your development and legacy branches . My point seems to be I ve seen branching used inefficiently : code becomes stale and then not used the merge becomes harder than the original problem . Only your option 1 makes sense to me . In general : .. . .. . 1 . You should think your code works before someone else sees it . 2 . Favor the head over a branch . 3 . Branch and check-in if someone else is picking up the problem . 4 . Branch if your automated system or testers need your code only . 5 . Branch if you are part of a team working on a problem . Consider it the head see 1-4 . With the exception of config files the build processes should be a checkout and a single build command . It should not be any more difficult to switch between clones than for a new programmer to join the project . I ll admit my project needs some work here . Comment : thanks for the answer but it seems like you re addressing it within the context of a traditional centralized VCS like svn . In hg or any DVCS your commits are local until they are pushed pulled so it s perfect safe and recommended to commit before testing . Comment : I mostly use svn so I m sure it affects my perspective . In hg after a push does the log show a difference between the push commit and local commits Do you use github It s great but it can be difficult to figure out which repository to clone- which fork contains the bug fixes you need or which is active vs abandoned . Coming back to branching I can see how many commit points helps the author . I think you re saying hg protects other developers from seeing the interim commits because they are not pushed . I think integration tests are where this might not be true . Comment : sorry I didn t notice your comment . Once commits more accurately changesets are pushed they re no longer local . The log doesn t show whether a changeset has been pushed . The outgoing command tells you if it hasn t . There s no protection on the local commits . Anyone can pull them if they want to .", "Question : This is a best practice question and I expect the answer to be it depends . I just hope to learn more real world scenarios and workflows .

Not merging down before you run tests . .. . Answer : I would always use named branches because that lets Mercurial do its job : to keep your project history and to remember why you made which changes in what order to your source code . Whether to have one clone or two sitting on your disk is generally an easy one given my working style at least : .. . .. . 1 . Does your project lack a build-process so that you can test and run things right from the source code Then I will be tempted to have just one clone and hg up back and forth when I need to work on another branch . 2 . But if you have a buildout virtualenv or other structure that gets built and that might diverge between the two branches then doing an hg up then waiting for the build-process to re-run can be a big pain especially if things like setting up a sample database are involved . In that case I would definitely use two clones one sitting at the tip of trunk and one sitting at the tip of the emergency feature branch . Comment : I voted up but didn t accept this because I mentioned named branch myself and I was asking for alternatives : We do have a build-process not very modern like the code base itself so 2 is indeed the argument for using two clones . However it can be a pain to switch your debug workflow between the two clones for example you d need two launch configurations in Eclipse .

Answer : One notion is to make the subrepo not the repo to which you have no write access but a clone of your own based on their repo . cd myclones hg clone http : notmydomain.com their-repo my-clone-of-their-repo .. . .. . and in your project s .hg hgrc you use a subpaths section to map their URL to your local clone : .. . .. .

In the old days of the web pages were typically written in two versions : One for Netscape Navigator and one for Microsoft Internet Explorer . When the web-standards were made at W3C browsers could not just start using them as doing so would break most existing sites on the web . Browsers therefore introduced two modes to treat new standards compliant sites differently from old legacy sites .

Comment : IE 10 and non ie browser use do the quirks mod according to the description of whatwg : Quirks Mode https : quirks.spec.whatwg.org Comment : Quirks is an IE specific thing Chrome uses a different engine which - unless deployed behind a strict enterprise managed network - is generally automatically updated . The idea of targeting specific browser versions is an outdated concept you should instead check for supported features https : modernizr.com . .. . Answer : Firstly no there is no IE6-compatibility mode . The XU-compatible modes start at IE7 mode . Now to answer your question : All the major browsers have implemented quirks-mode and it will be used in cases where the site doesn t provide a DOCTYPE or uses one that triggers quirks-mode . You can check for quirks-mode in any modern browser by checking that document.compatMode BackCompat .. . .. . However one of the major problems with quirks-mode is that it is not consistent between all browsers . In particular older versions of IE will render quirks-mode pages differently from other browsers . In addition IE considers quirks-mode to be a compatibility-mode for IE5.5 . Because of this it disables most of the browser features that have been implemented in later versions in order for the page to render as closely as possible to how it would have done in IE5.5 . Other browsers do not do this for them quirks-mode is simply a case of changing some styling defaults box-sizing being the main one they don t disable any features for quirks-mode so they will render quirks-mode pages quite differently to IE . In addition to the above IE11 is different again from earlier IE versions . IE11 has two separate quirks modes : One is the IE5-compatible mode described above the other is intended to be compatible with the quirks modes in other browsers . These two modes can be triggered in different ways but it can be confusing and not always obvious which one you ll get . For all of these reasons you should avoid quirks-mode . Stick with standards mode and you will get reasonably consistent rendering across all browsers .", "Question : With all the latest browsers like IE9 FF4 ever updating chrome etc . do we still need quirks-mode If yes where is it useful In which scenario Comment : avoid the trouble with IE memory-leaks when in quirks-mode .. . Answer : Quirks mode is designed to allow much older websites to work in comparatively newer browsers . New development should never be done in Quirks Mode but Quirks Mode will stick around as long as there are still old un-updated websites that require it ie forever .", "Question : With all the latest browsers like IE9 FF4 ever updating chrome etc . do we still need quirks-mode If yes where is it useful In which scenario Comment : avoid the trouble with IE memory-leaks when in quirks-mode .. . Answer : No . You should never use quirks-mode . It ceased to be of any relevance once IE 5.0 and 5.5 stopped being used . Those were the last browsers which did not support standards mode so any sites which needed to include support for them would have needed to be able to work in quirks-mode . However IE6 along with all versions of all browsers released since then supports standards mode . Some of them still carry legacy support for quirks-mode but you shouldn t allow them to use it . it s triggered if you neglect to include a DOCTYPE at the top of your HTML code which is why you shold always declare a doctype .. . .. . In the unlikely event that you need to support IE5 then use quirks-mode . Otherwise avoid at all costs . If you are maintaining code that uses quirks-mode then you should take the time to convert to use standards mode . If it s a public-facing website then using quirks-mode now should not even be contemplated as it will look hideous in a lot of modern browsers . Even if it s in a corporate environment then you I would strongly reccommend converting it to standards mode as even IE6 users will benefit from that if nothing else it ll make their eventual upgrade to a newer browser less painful . The only time you won t be able to use standards mode that is if you have a client who is still stuck with IE5 .

Answer : According to http : www.quirksmode.org css quirksmode.html : The problem was that some pages written in quirks-mode did have doctypes .

Answer : in html5 page write DOCTYPE html start with page can change to document.compatMode CSS1Compat", "Question : I m working on a page that when I load into IE8 and view the developers tools it tells me that page default is quirks-mode .

I can t understand why page default isn t IE8 standards Only thing I can think of is that to get to this page I first have to log in to an application and the first pages I must traverse are old quirks-mode pages . Does IE decide on which mode to use at a server level or is it supposed to decide page by page Thanks Comment : you try closing out all your IE8 windows and loading again Comment : this solved my quirks-mode problem : stackoverflow.com questions 6294301 http : stackoverflow.com questions 6294301 dreamweaver-causing-quirks-mode-in-internet-explorer .. . Answer : Does IE decide on which mode to use at a server level .. . .. . Not generally no . There is the ugliness of the compatibility view list http : blogs.msdn.com ie archive 2009 02 16 just-the-facts-recap-of-compatibility-view.aspx which is site-specific but that only kicks you back to IE7-style-Standards Mode not IE5.5-style-Quirks-Mode . Your code otherwise looks OK as long as that DOCTYPE is the very first thing on the page . IE will be forced to document.compatMode BackCompat if there is a comment PI XML declaration prior to IE8 or any non-whitespace textual content before the doctype . If a control character has snuck in that you can t see in your text-editor that could do it . Example problem page Comment : You got it Issue was that doctype declaration was not absolutely first thing on page . Thanks Comment : in my case i have some session and some header redirect but if you echo the code after that it will work : echo DOCTYPE html PUBLIC - W3C DTD XHTML 1.0 Transitional EN http : www.w3.org TR xhtml1 DTD xhtml1-transitional.dtd . you can use any other doctype", "Question : I m working on setting up a page and am having difficulty with getting it to look well across browsers actually just IE as it renders properly for mozilla and webkit . I m wanting to rule out quirks-mode before seriously considering old IE bugs fixed since IE6 . The container page has a declared doctype however the iframe code does not . Will the iframe content be rendered in quirks-mode because it does not have a doctype or standards mode because the container has a doctype The source follows this scheme : .. . Answer : Prior to IE9 the webpage within the iframe would render according to its own doctype not according to the doctype of the parent container . However in IE9 Microsoft changed the behavior so that the child iframe inherits its doctype rendering from the parent container . Note that IE9 will still behave in the traditional manner iframe honors its own doctype whenever compatibility view is used . The best workaround for folks in your situation--writing a standards compliant container page but needing to include an iframe with a quirks-mode page--is to add either of the following meta-tags between your doctype and the opening tag in the parent page . These tags will essentially tell IE9 to pretend it is IE7 or IE8 . Including in the emulation is the logic used to determine rendering mode for the child iframe . The downside of this workaround is that you will not be able to use any of the new features supported by IE9 in your parent page but that is probably preferable to massive rendering errors in the child page . See http : web.archive.org web 20110905060718 http : www.sitepoint.com forums html-xhtml-52 ie9-iframes-doctypes-you-743000.html for more information . Comment : is there any other slution that enable executing parent IE9 standards mode Frame along with quirks or EmulateIE7 child iframe Comment : @mikepr : Preferable No it isn t . Fact is you shouldn t produce HTML with quirks-mode - ever . Some important MS products do btw with no workaround.. . Comment : Oh and by the way : Stop upvoting this it sounds good but it doesn t work . Comment : While I agree that this does not work in all situations it does reduce some of the issues and does deserve to be upvoted . Unfortunately you sometimes cannot control what is contained within your iframe and therefore cannot control if it s standards compliant . I ve personally had an issue where this solution resolved the problem at least temporarily until the other app could be updated to be standards compliant .

I know that I can compare two NDepend builds and have code and metric diffs but what I m looking to do is compare the same single metric or metrics over N builds to see ongoing trends . I m sort of assuming that there isn t a tool that does this currently and that I ll have to roll my own but if there is one out there I d sure love to hear about it before investing the time . So does NDepend itself support anything like this or is there some sort of utility that already exists that I could use I m also open to suggestions for other technologies that would accomplish this besides NDepend though I have a strong preference for NDepend due to already having invested in it and being familiar with how it works .

Comment : SO the task is not achievable at all with NDepend Comment : No it is not achievable at all . .. . Answer : It s difficult or impossible to do with NDepend . NDepends shows which methods are calling specified method and not count in this situation them and even not count them recursively or through call-graph . So try to use other techniques . By first of all why you need such metric Some kind of method rank Anyway a pretty simple way to achieve it is using RegEx experssion . You can use also NDepend API or regex and ndepend api together . For example get all method names from source code base using nDepend API and then using regex for each method name count matches except method definition itself .

A few assemblies contain generated code that needs to be ignored by NDepend . Is there a way to do this Preferably an entire namespace . .. . Answer : Code Query and Rule over LINQ CQLinq http : www.ndepend.com Features.aspx CQL indeed provides a facility to ignore generated code . There is the convenient predefined domain named JustMyCode of type ICodeBaseView http : www.ndepend.com API webframe.html NDepend.API NDepend.CodeModel.ICodeBaseView.html . The domain JustMyCode represents a facility of CQLinq to eliminate generated code elements from CQLinq query results . For example the following query will only match large methods that are not generated by a tool like a UI designer : .. . .. . The set of generated code elements is defined by CQLinq queries prefixed with the CQLinq keyword notmycode . For example the query below matches methods defined in source files whose name ends up with .designer.cs : .. . .. . The CQLinq queries runner executes all notmycode queries before queries relying on JustMyCode hence the domain JustMyCode is defined once for all . Obviously the CQLinq compiler emits an error if a notmycode query relies on the JustMyCode domain . There are 4 default notmycode queries easily adaptable to match your need .

Comment : I m referring to the ability to change all the queries at once . Use case - Copy all the queries using the provided Copy to Clipboard Default CQL Queries in the CQL Query Edit options . Then using the regex tool of choice modify all the queries to ignore a particular namespace or to honor the NDepend Generated attribute or whatever other global change you want to make to the criteria of the CQL statements . Now how do I easily replace the default queries for the NDepend project with these updated modified queries Comment : Actually copy-paste from to CQL Query Explorer Group use a XML format in the clipboard you could copy this XML modify it and then paste it .

Sample rule : .. . .. . enter image description here http : i.stack.imgur.com DJ6Ej.jpg .. . Answer : Why does NDepend count Static fields as LOC for a method .. . .. . It is because when you do a static field inline initialization it adds a line of code to the class constructor . Actually as soon as you have one static field inline initialization in a class the C compiler creates a static-constructor for your class . So if you have N static field inline initialization you have a method the class constructor that has N Lines of Code . The large method that NDepend reports here is named BassAttributeNames..cctor .

Visual Studio 2010 Comparison http : www.jetbrains.com resharper documentation comparisonMatrix R5.html .. . Answer : Prosseek this is a good question you are asking . I have tested VS options and most of third-party options . From my experience third-parties tooling are always more convenient whatever the area covered . I agree with Ladislav Mrnka opinions : VS Ultimate provides large feature set out of the box but many features are like basic implementation . In more details : .. . .. . R is more subtle and relevant than VS equivalent when it comes to read edit and refactor code . NCover is as fast as VS coverage but it doesn t come with the frictionfull instrumentation phase . Also NCover proposes more interesting facilities to harness coverage results . DotTrace is faster and easier to harness than VS profiler both for performance and memory-management . There are also interesting alternatives like RedGate ANTS performance and memory profilers . TestDriven.NET is more adapted to run tests than VS test integration especially because it integrates with most of third-party options as a consequence if you are only using VS tooling TD.NET is useless . My opinion is certainly biased concerning NDepend since I am part of the tool team . An objective and measurable fact is that NDepend is 10 to 100 times faster concerning dependency graph and matrix and I encourage you to verify this fact by yourself NDepend comes with a trial http : www.ndepend.com NDependDownload.aspx .

Answer : CppUTest http : cpputest.github.io index.html is the perfect fit for embedded C development since it is the only testing framework that allows to mock free functions in your case write to i2c and read from i2c .

Anyway the following code shows how to do it . Your Unit Under Test UUT written in a way that is compilable next time you ask a question on SO please make the effort : .. . .. . As you wrote we need to fake or more exactly we need to mock write to i2c and read from i2c .

Please refer to the CppUMock documentation for details . This is just classic CppUMock boilerplate . Last part is the Unit Test : .. . .. . This UT will actually give 100 branch coverage . Again I cannot explain all the details . If you observe and compare test cases somethingA and somethingB you will see what is needed to cause the UUT to once go in the path that calls somethingA and once to go in the path that calls somethingB .

For inherits of C function in CppUTest I should write .. . .. . Is any alternative to inherit all C project into Cpp for CppUTest What is the disadvantages of extern in CppUTest .. . Answer : Well one alternative is of course to move the extern C declarations into your C-project s headers protected by if defined cplusplus of course . That will however mean that you have to go through the entire project and fix it . It sounds as-if just doing the above in your test code which is where you re using C++ would be easier . Many people do that as a way to make their C code usable from C++ .

The only thing I find when I download CppUTest and Unity is a ton of folders with makefiles and stuff and some READMEs that for me are like written in Chinese .

What do I have to do to compile it and run the test I wonder if you have experience with this tools and can give me some tips and advices . Thank you and best regards . Comment : http : cpputest.github.io manual.html seems clear to me . But I miss why you think embedded C and cygwin should be related . Comment : Well I need Cygwin to follow the examples in the book . I didn t go much further in the book but I guess that you can simulate hardware in some way for example if you have to write to an array of leds you just need the address where they are located but the program doesn t actually care if this address is actually connected to hardware or not so you could just have virtual leds .

There are some global-variables and structures which are not hidden in the module.h file . I use this variables in some test case but nowhere else so I thought it s a good idea to set them to static . In my test cases I extern these variables and fill with test values . But if they will be static-variables I can t reach them from the test case . I don t want to write getter and setter methods and put it to the .h file because I want to hide this variables . I know if I include the .c file into my test case I can see the static-variables . Is there any other way to fill these variables I use cygwin and gcc the test framework is CppUtest . Thanks in advance . Comment : Apparently you want to debug rather than perform unit-testing .. . .. . Answer : Often its a good idea to create these static-variables in a separate file some like to call it scaffolding so that you can get away from including the .c . The basic theory behind this is that if you are always including .c files it quickly becomes impossible to unit test since the whole idea of unit-testing is drilling down and testing one bit of code without depending on the rest of it . Once you re including all these exterior .c files you aren t doing this . Comment : Thanks for the advice it sounds better than I include the whole c file to the test case . But.. .

Comment : Hello Ross Thanks your suggestion helped moving the compilation forward . You may post it as answer I check it as correct and we close this question . .. . Answer : The No such file or directory error is a preprocessor error . It is telling you that the include file cannot be found in the include file path . Your IDE will have a way to specify the include path . If you are using make then you will want to use the -I option .

When running my app the web page renders a message suggesting the WidgetSet does not contain the add-on . screen shot of running app with message about WidgetSet does not contain implementation http : i.stack.imgur.com fhQgz.png .. . .. . That add-on instructions link leads to this page https : vaadin.com directory help using-vaadin-add-ons . Little information is provided . Even worse : None of the info is relevant to the current multi-module Maven archetype for new Vaadin apps . If there were any documentation telling me exactly what to do in adding an add-on and recompiling my WidgetSet I d gladly follow it . I found Using Add-ons in NetBeans https : vaadin.com directory help using-vaadin-add-ons netbeans but it is outdated . I opened a ticket http : dev.vaadin.com ticket 16723 asking for a new edition of that page . .. . Answer : Hack .. . .. . I found one hacky workaround : Put Maven dependency in both the -ui and -widgetset sub-module projects .pom files . I m trying to install Vaadin Charts 2 . So on the Directory page for that product I grab the Maven dependency XML snippet : .. . .. . I open two of the .pom files and paste that dependency into both . screen shot of two .pom files in list under -ui and -widgetset folders http : i.stack.imgur.com EmKo4.png .. . .. . Then I context-click on the -parent module to choose Clean and then choose Build With Dependencies . Lastly run the project and find the add-on now working . Note this workaround does not involve an command-line incantations with mvn . Works entirely within NetBeans which calls Maven on our behalf . This is a tricky kludge in that when an update of your add-on becomes available you will need to update both dependency declarations . There must be a better way .", "Question : null .. . Answer : I am using Vaadin Charts and I have a column chart with time line set . I read that you can customize the time buttons that set time range of the range selector . I am talking about the buttons that appear at the top left corner of the chart when you enable time line in vaadin-charts 3 . Chart with timeline enable . I took this image directly from Vaadin Charts documentation . http : i.stack.imgur.com 5G4gB.png .. . .. . What I want to do is to change the value of those buttons next to the Zoom label . I checked the javadoc and apparently you can do it by calling the setButtons method . But the thing is that it says that it is an array of configuration buttons and when I go into the Buttons class I cannot see any array . I just need a simple way to set the values to minutes instead of months and years which is the default-value of the buttons .", "Question : null .. .

Answer : Looks like DevInstructions.md has been outdated for a while thanks for noticing I ll create a ticket for that . About running the demos if you re using only maven you need to run install in parent project and then jetty : run in demo project . Note that install might fail for some modules if you don t do the recursive clone because submodule will be missing but the relevant modules will be built and jetty : run should work for demo . If you are using Eclipse and have workspace resolution importing demo examples and addon modules should be enough to be able to use jetty : run in the demo .", "Question : null .. .

If the add-on contains a custom client-side widget as is the case for most UI component add-ons it is required to create and compile the widgetset before running the application .

Comment : OpenGL s always been open-source - that s where the Open comes from : P The non-open thing it spun off of was SGI s IRIS GL . There should not be different APIs for each vendor maybe you are thinking of extensions .. . Answer : 1 . OpenGL is an open specification . Some of the implementations are open-source like Mesa3D . Usually implementations come with your graphics drivers . 2 . There are many standards like OpenGL OpenGL ES for mobile and soon glNext not named yet . 3 . Most modern implementations drivers support OpenGL 3.3 Core Profile and using older fixed-function pipeline glBegin glVertex glMatrix etc . is considered deprecated . Comment : OpenGL ES is used outside mobile-devices as well . For example Sony s Playstation 3 uses OpenGL ES 2.0 as a cleaned up version of desktop OpenGL .", "Question : every introduction and sample that I can find seems to use GLUT or some other framework to initialize OpenGL .

IDK how wide it s supported today though . Comment : As a GUI complement tiny file dialogs offers several function-calls . It s a single C C++ cross-platform file to add to your project.It has no init and no main loop . .. . Answer : GL is an API and GLU is an utility library on top of GL . It s completely operating-system independent . OpenGL initialization and extension fetching are platform dependent operations . Therefore you can do about nothing with OpenGL alone . GLUT is fast insufficient and terribly poor library and about only it does is that it initializes the opengl context and provides some primitive mouse keyboard input modules to get you ongoing . Win32 provides tools to initialize opengl context as well . For linux you could check out GLX . Also if you want a system independent way of doing it then you could check out SDL . For different programming-languages there may be utilities that provide you a platform independent desktop API .", "Question : I used to think that Tesla will not support OpenGL API but recently leanred that Tesla products also can be used on visualization via OpenGL . I have a workstation in which there are 2 Intel E5 CPUs and 1 Tesla C2050 . According to https : developer.nvidia.com opengl-driver Tesla C2050 should support at least OpenGL version 3 . Now I d like to run a render service program using OpenGL 3.3 on that workstation but without success . The following is what I tried . If I login through RDP remote desktop the supported OpenGL version is 1.1 due to the virtual graphics adapter . Here I used tscon commond to reconnect to the pysical console . As a result the RDP connection lost . When I reconnected I saw all the windows resized to 800 600 and the detected OpenGL support was still 1.1 . If I login with a monitor pluged to some kind of integrated graphics adapter the supported OpenGL version is still 1.1 maybe because the program was started within the screen pluged to the basic adapter . BUt the Tesla GPU does not have a grpahics output port . I wonder how should I config the host to enable the use of Tesla GPU for OpenGL based rendering . .. . Answer : I have solved this problem . First in fact the Tesla C2050 is dedicated video-card and has one DVI display port . What is more important is that the BIOS on motherboard was set to start up on integrated GPU . Changing this config to PCI-E card solves the problem that unable to access Tesla card . Next about graphics API support . The official driver on NVIDIA site is offering support for OpenGL 4.4 . And the Tesla card can be used to render via OpenGL just as the same as Quadro or Geforce card .

Answer : To me speaking as a graphics programmer in a large CAD company there are currently three things that retain OpenGL of beeing dropped in favor of Direct3D 10 11 for existing CAD DCC applications : .. . .. . 1 . Legacy . Most of CAD softwares are more or less hardly tight to OpenGL concepts . Rewriting everything around D3D philosophy is not always manageable technicaly speaking and depending on the ability willingness of the company to throw resources at it . Secondly it could have negative impacts if something goes wrong functionnality speaking and or performance wise and company would just not take the risk of delaying a major release because of an API and architecture switch . 2 . Peoples . Peoples in those old-boy industries are fairly conservative . They prefer spending money time on dealing with IHVs regarding all OpenGL driver issues they could have or simply won t recommend using graphics from a specific IHV e.g . Intel or ATI . Plus I believe that the automotive aerospace industry customers like Boeing Airbus TMC BMW etc don t care that much of having Quadros only workstation . Hardware is still cheap in regard to software licence prices . 3 . Future trends . With future generation of processors like Llano Larrabee Fermi and products that will follow it s definitely worth to invest R D budgets on how to program and develop new languages apis frameworks for those future hardwares in term of graphics as well as non-graphics tasks . CAD industry has huge cycles and won t move if not for a truly disruptive technology . So D3D might just come a bit late for big CAD players except Autodesk of course which is a particular case .

Answer : Does OpenGL use or depend on EGL No . You can run OpenGL without EGL . But is possible to have EGL implementation capable to create desktop OpenGL context . That s because EGL s eglBindAPI int api https : www.khronos.org registry egl sdk docs man html eglBindAPI.xhtml allows EGL OPENGL API EGL OPENGL ES API or EGL OPENVG API . But if you ask : .. . .. . Does OpenGL-ES use or depend on EGL The answer is yes but there are exceptions . Currently 2015 you have several implementations of OpenGL-ES that relay on EGL to create graphics context : Google ANGLE PowerVR ARM MALI Adreno AMD Mesa etc . But on recent releases of NVIDIA https : developer.nvidia.com opengl-driver and Intel drivers you can also request OpenGL-ES contexts directly where extensions WGL EXT create context es profile and WGL EXT create context es2 profile are available Windows .

Answer : D3D makes you pay the Microsoft strategy tax . That is D3D serves two masters . One is giving you features and performance . The other is to ensure lock-in to other MS products and the Windows platform generally . This has some consequences for you : .. . .. . 1 . A D3D app won t run on anything but Windows including Xbox . Maybe you don t think that s important now . But if down the road you want to run on Mac Linux PS3 future consoles etc . you may be glad you chose the platform-independent choice . 2 . MS can make some arbitrary decisions . Will the next version of D3D only run on an OS that requires new hardware is expensive and lots of people don t want to upgrade to Will they make some other future decision you don t agree with 3 . Historically OpenGL has led D3D in quick exposure of new HW features . This is because there s a mechanism in the standard for vendors to add their own extensions and for those extensions to eventually be folded into the main spec . D3D is whatever MS wants it to be with input from vendors to be sure but MS gets veto power . You could easily be in a situation like with Vista where MS decided not to expose new HW features to the old DX and only make the new DX available on Vista . This was quite a headache for game developers . Now then this is the flavor of reasons why a professional app CAD animation scientific visualization GIS etc . would favor OGL -- apps like this want to be stable for many years need ongoing maintenance and improvement and want to run on many platforms . This is in contrast to games which quite frequently are only on one platform will be released but generally not maintained there likely won t be a 2.0 an update for another OS three years hence don t need to support older HW etc . . Games want maximum performance and only need to work for a short time window and on a fixed number of platforms . If they need to target Windows anyway and D3D is a little faster that may be the right choice since the negative D3D consequences won t hurt them like it would for a CAD app say .

Should we take into account of GPU while Coding No way The OpenGL API is a layer between your application and the hardware . This is largely correct for desktop graphics as all GPUs are immediate renderers however this is NOT the case in mobile graphics . The Mali GPUs use tile-based immediate-mode rendering . For this type of rendering the framebuffer is divided into tiles of size 16 by 16 pixels . The Polygon List Builder PLB organizes input data from the application into polygon lists . There is a polygon list for each tile . When a primitive covers part of a tile an entry called a polygon list command is added to the polygon list for the tile . The pixel processor takes the polygon list for one tile and computes values for all pixels in that tile before starting work on the next tile . Because this tile-based approach uses a fast on-chip tile buffer the GPU only writes the tile buffer contents to the framebuffer in main memory at the end of each tile . Non-tiled-based immediate-mode renderers generally require many more framebuffer accesses . The tile-based method therefore consumes less memory bandwidth and supports operations such as depth testing blending and anti-aliasing efficiently . Another difference is the treatment of rendered buffers . Immediate renderers will save the content of your buffer effectively allowing you to only draw differences in the rendered scene on top of what previously existed . This IS available in Mali however is not enabled by default as it can cause undesired effects if used incorrectly . There is a Mali GLES2 SDK example on how to use EGL Preserve Correctly available in the GLES2 SDK here .. . .. . The reason the Geforce ULP based nexus-7 works as intended is that as an immediate based renderer it defaults to preserving the buffers whereas Mali does not . From the Khronos EGL specification : .. . .. . EGL SWAP BEHAVIOR .. . .. . Specifies the effect on the color buffer of posting a surface with eglSwapBuffers . A value of EGL BUFFER PRESERVED indicates that color buffer contents are unaffected while EGL BUFFER DESTROYED indicates that color buffer contents may be destroyed or changed by the operation . .. . The initial value of EGL SWAP BEHAVIOR is chosen by the implementation . .. . .. . The default-value for EGL SWAP BEHAVIOUR on the Mali platform is EGL BUFFER DESTROYED . This is due to the performance hit associated with having to fetch the previous buffer from memory before rendering the new frame and storing it at the end as well as the consumption of bandwidth which is also incredibly bad for battery life on mobile-devices . I am unable to comment with certainty as to the default behavior of the Tegra SoCs however it is apparent to me that their default is EGL BUFFER PRESERVED . To clarify Mali s position with regards to the Khronos GLES specifications - Mali is fully compliant .", "Question : I m writing an implementation for OpenVG http : www.khronos.org openvg and OpenGL ES http : www.khronos.org opengles in Go http : golang.org both of which depend on the Khronos EGL API http : www.khronos.org egl supposedly to ease portability I guess .

Answer : There is no relationship between OpenGL and EGL . EGL generally does not run on desktops and there is no ability to create a desktop OpenGL context through EGL . OpenGL contexts are instead created and managed by platform-specific APIs . On Windows the WGL API is used . On X11-based platforms GLX is used . And so forth .

It provides the minimal set of OpenGL functions compatible across all platforms but you can use OpenGL functions specific to each platform too e.g . full OpenGL on desktops . .. . Answer : Android supports OpenGL ES 1.0 which overlaps with OpenGL 1.3 so this should be possible but it is not as simple a just replacing the jar files at runtime . It is a good idea to try to reuse as much as possible of you application across both platforms . Anyway it is generally good practice to isolate the rest of you code from external dependencies such OpenGL even if you don t specifically need OpenGL ES support . You never know what API platform you may want to port your application to in the future . There are 2 options that are available . The first is to hide the OpenGL implementation behind an interface that the rest of your application uses and then provide separate Jogl and Androide implementations . Depending on which platform you are running on you can then choose to instanciate the correct implemenation at runtime using the factory-pattern . As OpenGL ES and OpenGL are very similar the effort required to maintain this should not be too high providing you stick to the common functions . The other option is to try and use Jogl2 which has support for profiles . These appear to provide exactly what you need but Jogl2 is still in beta . The bottom this page talks a little about profiles : http : kenai.com projects jogl pages FAQ .. . .. . Profiles allow Java applications to be written in a way which allows compatibility with multiple OpenGL versions at the same time . Since OpenGL ES GL for embedded systems has overlapping functionality with OpenGL itself it opened the opportunity to add even Profiles which bridge desktop and embedded implementations .

SDL can also be used for other graphics API s such as DirectX etc . QT http : en.wikipedia.org wiki Qt 28framework 29 .. . .. . QT is a cross-platform application development framework widely used for the development of GUI programs in which case it is known as a widget toolkit and also used for developing non-GUI programs such as console tools and servers . Conclusion .. . .. . OpenGL is an API for rendering 2D and 3D graphics . OpenGL-ES is a subset of OpenGL targeting embedded systems . WebGL is a JavaScript API for rendering 2D and 3D graphics based on OpenGL-ES . GLU is a utility library for OpenGL which mainly contains mapping functions . GLEW is a utility library for OpenGL which can handle loading of OpenGL Extensions . GLUT SDL is a library for handling various things like window keyboard and mouse control as well as listening . QT is a framework mainly for creating GUI . Thereby GLU GLEW GLUT is simply utility libraries for OpenGL which requires OpenGL if not they aren t for much good . SDL doesn t require OpenGL and isn t directly an OpenGL utility library mainly but it can be used with OpenGL but also with other things as well . Comment : Upvoted for mostly correct answer but SDL doesn t really require GL . It may use many different graphics backends . Comment : @keltar thanks for the response I fixed that part of my answer . Comment : You should mention that Qt has functions for using OpenGl . As of Qt 5.1 Qt Quick 2 only uses OpenGl and so now QOpenGL classes are a core part of Qt in QtGui module . Also QtCanvas implements WebGL for non web-applications and Qt3D is a new module for games and other applications that involve pairing 3D content with other functionality .", "Question : Is there anyone who can explain how hardware cursor works precisely How does it relate to the graphics I m drawing on the screen I m using OpenGL to draw how does hardware cursor relate to OpenGL graphics EDIT : For those who may be interested in this in the future I just implemented what is needed to show the cursor with the hardware . The implementation was in the kernel and to use it simple ioctl s were sufficient . Works perfectly . Comment : hi Luca I m interested to see your code with the ioctls for hardware cursor without X11 Can you link your code or a page manpage describing how to do it Thanks . Comment : Proprietary code sorry . I could only add information about how I implemented it . Comment : I would appreciate to see any such information i.e please answer your own question with reference to Linux and I will vote for you : or send me a message [email protected] Comment : I already added the relevant information in the question years ago . I used the system calls to move the pointer on the screen and set data related to the image to display as a cursor . I implemented this in the cursor driver of my environment which at the time was Qt for Embedded Linux . I don t think there is much more to say it was very simple . .. . Answer : Hardware Cursor means that the GPU provides to draw a small overlay picture over the screen framebuffer which position can be changed by two registers or so on the GPU . So moving around the pointer doesn t require to redraw the portions of the framebuffer that were previously obstructed . Relation to OpenGL : None Comment : +1 : for zero relation to OpenGL . Comment : No relation to OpenGL means that it is not important what is writing to the framebuffer I can use OpenGL X11 or whatever and the pointer would be placed the same way at the end of the chain . Is this right Thanks for your answer Comment : @Luca : Indeed . OpenGL is just one way to draw to the screen framebuffer . But either way the hardware cursor works independent from this . Comment : Would you say this is the best way to provide cursor to devices that needs high performance graphics Or maybe simply rendering a cursor with accelerated OpenGL implementation is better Thanks Comment : @Luca : Clearly a hardware accelerated cursor is the best solution . HW accelerated or not changing one bit in a OpenGL scene requires to rerender the whole thing or work with cache textures . HW cursors just work and they are easy to use Just use the graphics system s standard cursor image setting functions SetCursor in Windows XCursor in X11 MacOS X I don t know but the manual knows it with properly installed graphics drivers you ll get HW accelerated cursors automatically .", "Question : I m currently trying to get OpenVG up and running on my desktop . The problem comes here : I am will be developing an application for a Windows CE device with .NET compact-framework which has hardware-accelerated OpenGL ES 2.0 and OpenVG 1.0.1 based on TI OMAP35x if you re interested . The application will definitely use OpenVG for drawing and likely OpenGL for some effects if OpenVG doesn t offer them i.e . blur . Now I d like to develop on my desktop without the emulator see this question http : stackoverflow.com questions 653577 debug-net-compact-framework-app-locally-without-emulator-or-device . So I thought I just import OpenVG with P Invoke which was quite easy since the OpenVG people made their constants into real enums and though a procedural C API it translated very well into an object-oriented form with a Graphics class for drawing and Path Paint Stroke and Image objects . I also managed to get going with differently named DLLs and entry points http : stackoverflow.com questions 654089 dllimport-with-different-entry-points-different-dlls-for-the-same-import-in-diff . Oh and I imported EGL 1.3 also quite easy to translate to an object-oriented API . Until this point it sounded quite good . I thought I d just use the OpenVG reference implementation from Khronos but it is slow . Really slow . You know like clearing the surface taking literally a second So I thought fine OpenVG is a standard I ll just take one of the other implementations . Most of them are based on OpenGL which is what I want . Or isn t it No it s not . Creating an OpenGL ES 2.0 surface with EGL 1.3 supplied with the PowerVR Windows Emulation SDK for OpenGL ES 2.0 is not compatible with any OpenVG implementation I tried . Some of them require traditional OpenGL AmanithVG GLE the EGL version supplied by PowerVR doesn t support OpenVG . Most implementations don t even have EGL and use some bizarre functions to initialize the context - all of them assuming that an OpenGL context has already been created . OpenGL not OpenGL ES . Sigh . The only one I could get to work was AmanithVG SRE which is very fast for a software implementation and does not rely on OpenGL or EGL . It works but it is still far too slow for real-time animations . I can t believe that these things feel so wrong . I m really tempted to just use WindowsMobile.DirectX.Direct3D for which PowerVR supplies an emulation layer for Desktop Windows in the hope that the final Board Support Package will supply Direct3D as an OpenGL ES wrapper like it seems to be on many devices . So the question finally : .. . .. . Is there any OpenVG implementation for Windows Desktop systems that works with OpenGL ES 2.0 Bonus points if it works smoothly with PowerVR s OpenGL ES 2.0 emulation and the supplied EGL 1.3 . Or should I just try to use a traditional OpenGL 2.0 implementation on the Desktop But they re typically not supplying EGL as well . I don t want to have two initialization layers EGL and WGL . Or should I Note : this is not a .NET question because the problem is the very same without .NET . .. . Answer : I found a closed source OpenGL ES emulator for OpenGLES 2.0 and other versions from this site while searching for a solution to another problem I had : .. . .. . http : www.malideveloper.com developer-resources tools opengl-es-20-emulator.php .. . .. . Its closed source but it appears you can use it for your development purposes . Other then that you could write your own abstraction-layer that can switch between OpenGL and OpenGL ES -- I couldn t find one available from my searches . If you find one let me know because that is what I am trying to do .", "Question : The standard model has been that OpenGL is for professional apps CAD and Direct3D is for games . With the debacle of openGL 3.0 is openGl still the natural choice for technical 3D apps cad GIS Are there scenegraph libraries for Direct3D Of course Direct3D is windows only . Comment : This is crazy-subjective . Words and phrases like best and natural choice don t help . Having your question consist of multiple questions all subjective the year of the linux desktop also doesn t help . Consider rephrasing the question to be more specific . Comment : ok I will try ps . The linux desktop was a joke . Comment : The Tim Sweeney article link was great arstechnica.com articles paedia gpu-sweeney-interview.ars http : arstechnica.com articles paedia gpu-sweeney-interview.ars .. . Answer : Direct3D is only available on Windows and XBox . If you plan on targeting Unix or Mac in addition to Windows OpenGL is a good choice . Comment : Or equally importantly if you eventually decide to target Unix and Mac you should choose OpenGL to minimize conversions needed to support them . Comment : @Guvante : Sorry but no . Minimizing conversions is not the point at all in this business . It s all about reliability of graphics drivers time you spend on dealing with their issues .", "Question : I am working on a gaming framework of sorts and am a newcomer to OpenGL . Most books seem to not give a terribly clear answer to this question and I want to develop on my desktop using OpenGL but execute the code in an OpenGL ES 2.0 environment . My question is twofold then : .. . .. . 1 . If I target my framework for OpenGL on the desktop will it just run without modification in an OpenGL ES 2.0 environment 2 . If not then is there a good emulator out there PC or Mac is there a script that I can run that will convert my OpenGL code into OpenGL ES code or flag things that won t work .. . Answer : It s been about three years since I was last doing any ES work so I may be out of date or simply remembering some stuff incorrectly . 1 . No targeting OpenGL for desktop does not equal targeting OpenGL ES because ES is a subset . ES does not implement immediate mode functions glBegin glEnd glVertex .. . Vertex arrays are the main way of sending stuff into the pipeline . Additionally it depends on what profile you are targetting : at least in the Lite profile ES does not need to implement floating-point functions . Instead you get fixed-point functions think 32-bit integers where first 16 bits mean digits before decimal point and the following 16 bits mean digits after the decimal point . In other words even simple code might be unportable if it uses floats you d have to replace calls to gl f functions with calls to gl x functions . See how you might solve this problem in Trolltech s example http : doc.trolltech.com 4.4 opengl-hellogl-es.html specifically the qtwidget.cpp file it s Qt example but still.. . . You ll see they make this call : .. . .. . q glClearColor f2vt 0.1f f2vt 0.1f f2vt 0.2f f2vt 1.0f .. . .. . This is meant to replace call to glClearColorf . Additionally they use macro f2vt - meaning float to vertex type - which automagically converts the argument from float to the correct data type . 2 . While I was developing some small demos three years ago for a company I ve had success working with PowerVR s SDK http : www.imgtec.com PowerVR insider sdkdownloads . It s for Visual C++ under Windows I haven t tried it under Linux no need since I was working on company PC . .. . .. . A small update to reflect my recent experiences with ES . June 7th 2011 .. . .. . Today s platforms probably don t use the Lite profile so you probably don t have to worry about fixed-point decimals .. . When porting your desktop code for mobile e.g . iOS quite probably you ll have to do primarily these and not much else : .. . replace glBegin glEnd with vertex arrays .. . replace some calls to functions such as glClearColor with calls such as glClearColorf .. . rewrite your windowing and input system .. . if targeting OpenGL ES 2.0 to get shader functionality you ll now have to completely replace fixed-function pipeline s built-in behavior with shaders - at least the basic ones that reimplement fixed-function pipeline .. . Really important : unless your mobile system is not memory-constrained you really want to look into using texture compression for your graphics chip for example on iOS devices you ll be uploading PVRTC-compressed data to the chip Comment : 2 imgtec.com PowerVR insider sdkdownloads http : www.imgtec.com PowerVR insider sdkdownloads which archive for linux platform I am sure we can emulate glBegin on top of GLES implementation Comment : @rzr : Emulating glBegin is certainly possible but might be a bad idea . You may instead want to restructure the code . On that site you ll want to download PC Emulation archive for either OpenGL ES 1.1 or OpenGL ES 2.0 . Comment : the goal is to ensure a source compatibility first dont care about performance just want to build legacy apps .. . -- rzr.online.fr q opengl http : rzr.online.fr q opengl" ] }	[ "yes-answer-long", "yes-answer-short" ]	api	UNK_RELATION

OOP Interface in addition to procedural Prepared Statement Support Transaction + Stored Procedure Support Nicer Syntax Speed Improvements Enhanced Debugging .. . .. . PDO Extension .. . .. . PHP Data Objects extension is a Database Abstraction Layer . Specifically this is not a MySQL interface as it provides drivers for many database engines of course including MYSQL .

Answer : From the PHP documentation . http : is.php.net manual en mysqli.installation.php .. . .. . To ensure that the mysqli extension for PHP is enabled you will need to configure the PHP source code to use mysqli .

Answer : There are more than three popular ways to use MySQL from PHP . 1 . DEPRECATED The mysql functions http : www.php.net manual en ref.mysql.php are procedural and use manual escaping . 2 . MySQLi http : www.php.net manual en intro.mysqli.php is a replacement for the mysql functions with object-oriented and procedural versions . It has support for prepared statements . 3 . PDO http : php.net manual en book.pdo.php PHP Data Objects is a general database abstraction-layer with support for MySQL among many other databases . It provides prepared statements and significant flexibility in how data is returned . I would recommend using PDO with prepared statements . It is a well-designed API and will let you more easily move to another database including any that supports ODBC https : en.wikipedia.org wiki Open Database Connectivity if necessary .

In the mysqli documentation for Persistent connection http : php.net manual en mysqli.quickstart.connections.php they have written that : .. . .. . If a unused persistent connection for a given combination of host username password socket port and default database can not be found in the connection pool then mysqli opens a new connection . So does mysqli use connection-pooling for persistent connections If yes then what is difference between connection-pooling and persistent connections in mysqli If no then how does mysqli perform a lookup for a connection object for a persistent connection .. . Answer : in libmysql18 it looks for any existing default mysql sock port and tests it with the credentials . if it can t be found the c++ function clone is called creating the new connection object Resource . in certain cases this can result in a stack-overflow . i m not familiar with how it works in mysqlnd native driver . maybe someone else is . if you want more information about how it works install a version of facebooks HHVM-debug package and attempt to pass a connection via global in multiple nested functions . this can trigger a stack-overflow under HHVM which will show you every function called prior to the exception up to that point .

Answer : From the results you posted above it s not installing because it can t find the php-pdo package in any of the repositories configured on your server . It looks like you have made changes to your repositories as elrepo is not in either the version 5 or 6 distributions that I have installed . I would suggest you first list the packages availabe in these repositories as they may be packaged under a different name . Run yum list php to see an output of php packages . Yum will then tell you what is available installed and needs updating . Note : If you re on a shared host chances are that PHP is already installed and mapped to a specific version . Often times you ll see the version number in the package name so php might be a php4 install php5 might be a php version 5.2 and below install php53 might be a php version 5.3 install and yes I ve even seen a php6 package mapped to php version 5.3 . So it wouldn t be out of the ordinary if the PHP package installed on YOUR server includes a version number in the package name . Really depends on what repositories you re setup to use .

I need to edit faster and learn touch typing currently in the process and therefore I find a need to move to Vim . It has been now over one year I have trashed Windows and moved to Linux Ubuntu to be more precise and I am using the IDE Zend Studio http : www.zend.com products studio combined with Aptana Studio http : www.aptana.com for developing OO PHP5.3 websites . Although the IDE does everything I would need from an IDE which I will enumerate shortly it lacks the editing mode Vim would give . So my question is : how would I have all the same following killer features I already have within this IDE in Vim Here is the extensive list of features I need to keep the productivity at an high level for me : .. . .. . Code completion for PHP5.3 not just PHP5 and not just the PHP functions but any libraries that are added to the buildpath such as Zend Framework http : framework.zend.com and my own library . Code formatting I don t use it much except for XML files but that is something I would need soon as I will start to lead more people within my company and formatters will help to keep the code coherence . I use Oxygen XML editor http : www.oxygenxml.com within Zend Studio eclipse for editing Docbook XML http : www.docbook.org technical documentation . It has already proven of great quality to me and I would like to keep it . Syntax validation for any file extensions that can be used on the Web mostly for me would be PHP5.3 syntax html syntax not that important CSS Javascript that s why I have Aptana Studio integrated with Zend Studio their javascript editor is great with JQuery support .. . .. . Maybe a git integration just like EGit http : www.eclipse.org egit eclipse-plugin Not required but a nice addon . Debugging features already using it through the ZendDebugger .. . .. . Powerful searching within files .. . .. . I know that is a lot but I am already having all this within my IDE and as I said I feel the need to move to mode based editors like Vim to be more productive when typing and I feel the learning curve and time invested in setting up all of this will be well worth the effort . I know that there is Eclim http : eclim.org which integrates eclipse to its daemon and I am thinking of using just that if anyone has feedback on Eclim used with Zend Studio that would be appreciated . Along with Eclim if I need more vim plugins to achieve my needs I would gladly appreciate it if someone could direct me to them . .. . Answer : I m interested in using Eclim with Zend Studio as well . However I already have a Zend Studio Project and installing Eclim requires the creation of an eclim project . That process according to the eclim installation notes will create a .project file in the root directory of the project . And that means it will likely overwrite the ZendStudio .project file...which will corrupt my project files.. . something I don t want to do in case I decide that eclim is not for me . Let me know how it works out for you . Comment : Yeah I am using already set-up projects as well and won t be creating ones with Eclim since projects will get created using Zend Tool . When I get time to figure all that out I will let you know how I did it if I am able to achieve all my development quality and requirement attributes on vim . Comment : @trelayne You don t have to necessarily add projects using Eclim if you already have created them . As long as they were added in your workbench Eclim will be able to see them . I have never actually created projects with Eclim .

But I am sorely missing Notepad++ s CTRL+F box which includes Find All in Current Document and also a handy Find in Files . I mainly like having a search dialog pop-up at the bottom of Notepad++ and then being able to double-click on files having the string and they will open in a new tab . I finally realized that Zend Studio has both CTRL+F AND a CTRL+H searching feature but they don t operate quite like NPP . The Ctrl+F one seems to really just be good for stepping through the code but no dialog appears at the bottom . And Ctrl+H Search feature seems somewhat promising but I can t figure out how to simply search in the current file NOR have I reliably been able to search in a Working set or Selected resources if it s on a remote-server haven t tried local .

If the setting is not there I would file it as a bug . Comment : Yep I ve looked . There are no such thing it realy looks like a bug . .. . Answer : @MGriesbach : Actually PDT Eclipse does have this function under Source- Format .. . .. . @Sergei : Eclipse doesn t have this problem but this sounds like something is wrong with your config . Are you sure you looked through all the options You may also send an email to the Zend team this sounds like a pretty trivial bug on heir side as it encourages developers to write code not indented correctly . -- edit-- .. . .. .

Drupal console is not meant to manage dependencies . Composer works with private dependency . The only requirement is the installation of SSH keys for a git client . See : https : getcomposer.org doc 05-repositories.md using-private-repositories .. . .. .

One of those programs has caused my command-line to start displaying the current branch of git along with cryptic symbols that relate to the git-status .

In this case I m on the master branch and the refers to the git-status . While I think it s neat unfortunately git has also slowed my command-line dramatically . Therefore I would like to find out what has caused this change to git it did not use to behave like this and try to undo the features . I know that git is the reason for the slowdown because in my apps that do not have git everything works swimmingly . I also ran top and noticed that git is the only thing running while my system hangs eating up 33 to 50 of certain resources . I thought updating to a newer version of git would help but it made no changes . Currently I am running git version 2.7.1 . One of the following programs may have had something to do with this : drush ruby or compass . Unfortunately I can t isolate which program may have affected git this way and it s possible it s a different program entirely that I can t remember installing . Comment : None of these are related to the problem . I suspect you customized installed a profile for your shell bash zsh . It s coming from there . Check for a git plugin in your shell prompt . Comment : @Babar how do I check for a git plugin in my shell prompt .. . Answer : Installing drush caused the changes to the command-line . You will notice after installation of drush is complete it will mention it added a handful of lines to your .bashrc file including this one : .. . .. . If you open the file it references home vagrant .drush drush.prompt.sh you will see that this is where both PROMPT COMMAND and PS1 are being modified . Instead of completely deleting or overwriting drush.prompt.sh it may be best to modify it so as not to lose drush command-line customizations . However to completely overwrite it you can add something like the following to your .bashrc file . The .bashrc file located in your directory will modify only your profile . Here s an example that displays some nice info and a git-status that works much faster : .. . .. . You may not need to TZ line or can adjust it accordingly .

Keeping the original upload stream intact .. . .. . There are some things to consider though if you want to have the original .uploadStream still working namely you must not access nsIMultiplexInputStream instances at all these will break and you must check nsISeekableStream and rewind the stream . If you replace the stream with .setUploadStream anyway then these aren t much of a concern and can be ignored . Parsing .. . .. . How exactly you parse the GET style parameters is up to you and discussed in other answers http : stackoverflow.com q 901115 484441 already .

Please read the text in that page and the Development Kit instructions http : github.com oneclick rubyinstaller wiki Development-Kit in our wiki .

I hope this helps -- Freddy", "Question : I am split between the benefits of developing Java non-commercial webapps and deploying to something like Aptana or Google cloud or just going with a Slice Host account . Tomcat or Jetty and MySQL are really my only big requirements . Aptana and Google App Engine come with some cool Eclipse deployment options but does scalability really matter without a large user base for the apps Also both Aptana and Google App Engine seem to be in infant stages so I m wondering if there will be too many restrictions even for small time development . Anyone have experience with these .. . Answer : I can t speak to Aptana but Google App Engine is a radically different development experience from what you ll get with something like Slicehost . It scales differently i.e . you ve got the possibility of handling much larger loads but it s also totally different than running your own web app server e.g . Glassfish Tomcat JBoss etc . and coding using standard Java tools . With Slicehost or any hosted solution it s easy to setup your own development-environment locally which exactly mimics what you ll be running on the server . Same software same VM maybe even the same version of Linux . You could even move to a different host and still be able to setup that same environment . With Google App Engine you ll find yourself building on an emulator you don t really run BigTable locally so there s not a one-to-one correspondence between your environment and that on the server . There s no alternative place to move to and still be running in the same environment either . Also some perhaps many of the popular Java frameworks you might use for a web app development will either not work at all e.g . or will not work out-of-the-box see here for more details http : groups.google.com group google-appengine-java web will-it-play-in-app-engine . I m not down on the App Engine in fact I think it s really cool . If the demand for your apps is relatively low and therefore you re not in need of the huge scaling requirements but your traffic is not so low that you fit comfortably within the free allowance at Google then I would probably lean towards a hosted solution like Slicehost instead . Comment : I m slowly trying to write a java app on App Engine and your points are spot on . Your choice of frameworks is currently pretty limited which is the biggest drawback for me . I have yet to try to upload my app to their servers so I can t speak to the difference in environment but I would hope they would be similar enough to catch the vast majority of issues . I ll keep going because I suspect my traffic will be small enough to be free for a very long time .", "Question : I am new to ruby and Aptana I have used eclipse before I was wondering if when debugging in Aptana we can drop into irb to play around with things with current values set .

I ve got Flex Builder 3 I think that I ve got the standalone version but I m not sure . Both of them are Eclipse based . I don t want to cause a problem with either installation . Which version of Aptana should I download-- the standalone or plugin version How can I tell which version of Flex Builder 3 I ve got I m on a Mac . .. . Answer : Personally I have a standalone Aptana Studio 3 and a standalone Flash Builder 4 I had standalone versions of Flex Builder 3 and Aptana 3 before . I find that I prefer multiple standalone versions of Eclipse products because I see a degradation of performance in Eclipse and Eclipse-based IDEs when I load too many plugins into one . FWIW I have the following on my main system also a Mac : .. . .. . Eclipse Standalone 3.6 with Amazon Web Services ColdFusion CFEclipse and Java-related plug-ins for Java CFML project Aptana is installed as a plugin here for the occasional HTML CSS JavaScript work with these projects . Aptana Studio 3 for Rails work . Titanium Studio 1 for mobile development .. . Flash Builder 4 for when I have to do Flex crap . I know it might seem odd to have 4 IDEs at the moment I use Aptana and Titanium almost exclusively as my current workload is Rails and mobile development but I find that all four run GREAT as is and when I start conflating plugins and features I see degraded performance . I hope this helps a little Comment : Hi Craig Cool . Thanks for the help . I ll go with the Aptana standalone . Comment : Sweet Glad it helped out Laxmidi . Good luck with it :", "Question : I m a newbie in Javascript Programming . But I should be an expert . + and newbie in English Language also . .. . .. . Nowadays I got the assignment that I should make the company standard framework for web programmers . From my search results I think.. . Maqetta is suitable for UI Design Draft and.. . Aptana is suitable for JavaScript Programming . It s just my thought . and I m considering jQuery+jQueryUI+a.. . as Library Bases . So I ll set the standard IDE like this form : Eclipse + Maqetta Plugin + Aptana Plugin + jQuery +a Libraries. . for my Web Programmers . and Rough steps for programming are 1 . UI Designing using Maqetta.. . 2 . Script Coding using Aptana.. . Though I m a beginner for JavaScript but I have the duty on my Web Programmers I wanna ask for comments about this set-up . Is it possible Is it Not-Bad Is it Useful Thank you in advance.. . .. . Answer : Jon Ferraiolo answers on maqetta-users : .. . .. . The best way I can think of to use Maqetta and Aptana together would be to download Maqetta to run locally http : maqetta.org downloads and run it locally which will cause Maqetta to save the HTML CSS JS file it creates on your local file system.Then you could open any of those files using Aptana for source editing . .. . The ZIP file contains a README file inside with instructions . .. . When you install Maqetta locally into installfolder and run Maqetta from a browser for the first time it will create a installfolder maqetta users . You should see a single folder a . That s where Maqetta saves the files you create . You should be able to open those files in Aptana for source editing . Note that if you create multiple-projects via the New Project command each new project will get its own folder e.g . b c etc . Unfortunately there is no easy way to tell which of these folders map to which project except visual inspection .", "Question : My Rails development IDE is Aptana Studio http : aptana.com 3.0.5 running on Windows . The applications runs on Apache + ModRails http : www.modrails.com Phusion Passenger on a separate CentOS Linux machine . I have both Rails 2.x and 3.x applications . I would like to be able to use the debugger in Aptana Studio connect to the running application remotely . There are apparently some provisions for this but I was unable to figure out what I need on the server-side in my Rails application configuration .. . .. . I ve tried this : .. . .. . 1 . Using Rack : : Debug : It creates only unix-socket cannot be connected remotely . 2 . Using ruby-debug directly : .. . .. . I added this to my config environments development.rb : .. . .. . Sprinking my code with debugger statements stop the execution but I cannot connect to this instance from Aptana not to port 5000 and not port 5001 and I don t understand why I need two ports there . Also this method would be rather slow and too convoluted even if it worked I d like to have a more integrated debugging . Is it possible at all .. . Answer : The old steps for Netbeans are relatively close since Aptana RadRails and Netbeans share the same debugger core : http : blogs.oracle.com martink entry remote debugging debug whatever ruby .. . .. . Basically run the ruby app using rdebug-ide -p 7000 or whatever port you want then inside the IDE go to Run Debug configurations . On the left hand side select Remote Ruby Debug Session and then add a new configuration there the plus icon above the list . Enter the proper host IP name and port you entered on the command-line .", "Question : My code is neatly organized in CSSEdit groups but the others in my team use Aptana or other tools . Is there a CSS editor for Aptana or Eclipse that supporting CSSEdit groups EDIT Does Aptana or its editors allow for custom code-folding limits That would be already great . Thanks . .. . Answer : Definitely not Aptana and not any editor for Eclipse I know of since it s a very CSSEdit-specific feature . It sounds somewhat similar to the region functionality in Visual Studio though that generally does not show a folder hierarchy . I would suggest adding a feature request for Aptana at http : jira.appcelerator.org browse APSTUD", "Question : I installed the WordPress bundle ruble for Aptana Studio https : github.com aptana wordpress.ruble but it s only providing code assistance for a subset of WordPress functions . I d like code assistance for all WordPress core functions or as many as possible . My projects have PHP as their nature and are connected via SFTP to remote WordPress installations . After the bundle which hasn t been updated in over a year didn t provide everything I was looking for I tried using a local copy of WordPress as an external library then adding it as an external directory to the PHP Buildpath . Neither one added any more functions than the bundle provided . These actions were suggested in Aptana Studio Support https : aptanastudio.tenderapp.com discussions questions 969-can-aptana-3-do-code-assist-for-wordpress-projects and WordPress Answers http : wordpress.stackexchange.com questions 27063 aptana-wordpress-code-hinting . Am I doing something wrong or is the level of code assistance I m looking for not available .. . Answer : It s true that the WordPress bundle offers just some limited auto-completion support . Though including the local copy of another WordPress installation as a PHP external library seemed to solve this in the latest Aptana Studio version 3.4.0 as you already mention to have tried and as it is suggested in this one https : wiki.appcelerator.org display tis PHP+Development PHPDevelopment-AttachingPHPResources of the links that you pointed out . Here are all the specific steps I took so you can check if there was something different in the procedure you followed . Open the Preferences menu going to Window Preferences .. . Select Aptana Studio Editors PHP Libraries .. . Click New user library .. . Add the path to another local WordPress installation not the same WordPress files in the current project selecting the root folder of a freshly extracted WordPress download e.g . : C : wordpress-3.5.1 wordpress .. . Make sure the new library is selected in the user libraries list marking it with a checkmark next to the library icon . Apply the changes and press OK .. . Make sure your project is a PHP project . Right click the project folder select Properties Project Natures and mark the PHP checkbox . Now inside PHP code I get autocompletion suggestions for all core WordPress functions - and I can even go to check their source by pressing F3 on their function name . Comment : Thanks for your reply E . Serrano . Unfortunately that doesn t seem to have worked for me . I added the library and Aptana showed that it indexed it but I still don t get auto-complete for the majority of WordPress functions . I tested by opening an existing theme template file and typing various functions from the Codex Function Reference http : codex.wordpress.org Function Reference . I don t know what I m missing . Comment : It s amazing . I closed the project I was working on and after opening a new project the WordPress-related auto-completion is gone The right library is still imported there but I m experiencing the same issue you were mentioning . I ve tried adding the library again importing a different version deselecting the working set etc . with no luck . Comment : I realized autocompletion doesn t work in Aptana projects set only as Web Project . But it does work when configured as PHP projects . So you can have full WordPress code auto-completion in Aptana following the aforementioned steps and adding the PHP project type for that specific project right-click on an existing project Properties Project Natures Check PHP . A little P will appear on your open project folder and PHP code assist will use the included WordPress libraries from now on . Comment : My projects are already set to PHP projects but I still only get auto-completion for a few functions tested by opening an existing theme template file and typing various functions from the Codex Function Reference http : codex.wordpress.org Function Reference . Comment : Is PHP the Primary nature of the project Do you also have the Web project nature assigned to that project Alternatively have you tried assigning the source WordPress directories as External Directories in the PHP Buildpath tab inside Project Properties", "Question : I am new to both python and Aptana . I am trying to use the tweepy package in python . I have the following code from python s site http : packages.python.org tweepy html getting started.html : .. . .. .

I googled and found http : mitchfournier.com 2010 06 18 aptana-studio-and-undefined-variable-from-import-doesnotexist how to resolve the undefined variable error but it seems like a hack-a-round . In sum that link says to add get user to globals in the preferences . Being new to both Python and Aptana I just wanted to check to see if that is the best way to resolve it....it just seems like a hack . When I change tweepy.api.get user to tweepy.api.public timeline I get the same error and thus will have to manually add public timeline to the globals....It doesn t seem like the correct way when you have to manually configure each variable . thanks Comment : @DSM Reading between the lines a little I think it s a bug in Aptana Studio not Tweepy Aptana reports an error and highlights get user in red even though there is nothing actually wrong with the code . Comment : @JasonOrendorff : ah I see . Comment : @DSM...that s kind of what I think but being a newb wanted to check .

Specifically I want to install the jQuery Code Assist feature . I ve read that I should go to Help Install Aptana Features in both Eclipse and Aptana . Well this menu item doesn t exist in either . When I go to Help in Aptana the only options are : Check for Updates and Install new software . Same goes for Eclipse . I m using Aptana Studio 3 and Eclipse 3.7 . Comment : So I eventually found this link : Comment : So I eventually found this link : download.aptana.org tools studio plugin install frameworks http : download.aptana.org tools studio plugin install frameworks .

Searching around for that I found an Aptana posting from 2010 saying they don t support feature updates : aptanastudio.tenderapp.com discussions problems https : aptanastudio.tenderapp.com discussions problems 1852-aptana-3cant-install-jquery-plugin . .. . Answer : The process has changed . Instead you drop a library API file into your project : .. . .. . http : wiki.appcelerator.org display tis Using+JavaScript+Libraries Comment : when you drop a library file in at least with the Eclipse Aptana 3.0 plugin it doesn t work well . The only way to get the code-assist to come up is if you do something like test .add and then hit backspace and delete the last two d s and then you get the jQuery Code-Assist to appear . On top of that compared to Aptana 2.0 the code assist snippets that explain what the function does are completely useless and look like gibberish . There is no text explanations just what seem like regex expressions within the functions . Aptana 3.0 is broken and would recommend people just use 2.0 . Comment : I can t replicate what you are seeing . 1 I download the linked .sdocml file into my project 2 I type and I immediately get code hinting . I get the same after typing test . You may have downloaded the jQuery ruble which includes snippets that will behave like you describe i.e . .add 1 : selector elements html 0 . Snippets insert chunks of code and serve a different use-case . There is currently an issue with chaining snippets in jQuery which is encapsulated in this ticket : jira.appcelerator.org browse APSTUD-2445 http : jira.appcelerator.org browse APSTUD-2445 Comment : The .sdocml I used was the one listed on the page you provided above . The link on that page is : raw.github.com aptana javascript-jquery.ruble master support https : raw.github.com aptana javascript-jquery.ruble master support jquery.1.4.2.sdocml . Is that not the right link Is there a non-ruble .sdocml link Comment : That is the correct file . I did have an issue with the first time I tried it because it saved it as a .html file accidentally . Once I fixed that it worked . It sounds like either a bug or a mis-configuration . Can you file a ticket @ jira.appcelerator.org browse APSTUD http : jira.appcelerator.org browse APSTUD and someone will take a look Comment : I struggled with Aptana Studio 3.0 a lot too after upgrading from 2.0 . It seems that a lot of features don t work out-of-the-box anymore and need manual tweaking . Anyway make sure your project has at least the Web nature . Right-click your project in Project Explorer select Properties go to the Project Natures property and make sure Web is checked . It will ask you to close and re-open the project in Eclipse . You might find a lot of things working better after that .

Even if font-smoothing and ClearType are disabled in Windows IE still shows anti-aliased fonts which some users struggle to read especially at small font sizes . How can I disable all font anti-aliasing ClearType or otherwise in IE9 More details : .. . .. . Our company builds a web application which uses a lot of small fonts . With the release of IE9 some of our users have complained that IE9 s default anti-aliasing makes our small fonts fuzzy or blurry . So we need to help our users who ve installed IE9 and who want to turn off anti-aliasing . Also personally I have trouble reading small anti-aliased fonts so I d like a solution for my own use even for sites I don t control . In IE8 I could uncheck the Always use ClearType for HTML and then disable ClearType in the OS and IE8 would show all fonts aliased . But in IE9 this option is missing . After some research about the problem here s what I ve learned : the core issue is that IE relies on DirectWrite for text-rendering and does not support any of the newer rendering options which would draw text without anti-aliasing and respect the user s OS-wide default choices . Making things worse if you disable ClearType in the OS in some cases IE will fall back to DirectWrite s default non-cleartype anti-aliasing which is even fuzzier than ClearType .

Answer : The info here solves two problems : 1 . Getting rid of cleartype and font smoothing in IE9 2 . Getting rid of cleartype and font smoothing when IE10 is installed or installs itself automatically .. . .. . I had done a registery hack to turn off cleartype in IE9 : HKEY CURRENT USER Software Microsoft Internet Explorer Main UseClearType no and used a little piece of freeware to get rid of font smoothing in IE9 : https : softwareninjas.kilnhg.com Repo Open-Source Group DWrite-dll-Wrapper .. . .. . Then IE10 automatically installed itself and the blurry type was back . I tried uninstalling IE 10 which wasn t through the add remove programs interface but rather through the installed updates interface--removing the IE10 update . That ostensibly took me back to IE9 but the blurry type remained in spite of the fact that no was still the answer for cleartype in the registry and the two .dll files were still in my IE program folder . So I decided to uninstall IE9 and reinstall it . That also involved going through the installed updates interface and removing the IE9 update . I rebooted and expected to have to reinstall the program but my IE icon was still there . When I clicked it IE9 opened with nice sharp type .", "Question : First some background information . It seems that using the CSS3 @font-face rule can interact in unexpected and undesired ways with ClearType font renderingv in any browser on any version of Windows XP and above . I first documented this as a Google Font Directory bug http : code.google.com p googlefontdirectory issues detail id 44 when I ran into it . Further research seems to yield conflicting information having ClearType enabled or disabled can either help or hurt how a @font-face font renders in any web browser in Windows . Whether ClearType helps or hurts seems to be totally dependent on the font s being used and what kind of hinting is built into them . For example a thread on TypeKit s support site http : getsatisfaction.com typekit topics typekit fonts rendering horribly on windows based systems seems to point to font rendering problems when ClearType is DISABLED . However a jQuery plug-in http : allcreatives.net 2009 12 05 jquery-plugin-ie-font-face-cleartype-fix was developed to improve font rendering when ClearType is ENABLED but the plug-in only works in Internet Explorer . Interestingly the font used on the plug-in s demo pages does render poorly when ClearType is enabled but when it s disabled the two demo pages render identically correctly . So given all of that background information and prior research my question is : .. . .. . What s the best way compromise to ensure decent font rendering for modern browsers on all platforms regardless of Windows ClearType settings .. . .. . My first idea was to use stylesheets that include the @font-face fonts by default . JavaScript could detect the user s OS and if Windows is detected could programmatically modify stylesheet classes to use font-families that don t include the @font-face fonts so that system-native fallback fonts are used . I realized later that someone else also thought of this http : blog.costan.us 2011 02 quick-fix-for-ugly-font-rendering-in.html . It s a hacky and inelegant solution though . Ideally I want my web fonts to be usable regardless of the platform without relying on something like sIFR or Cufon .

Answer : I know that WPF disables ClearType text-rendering if it is in doubt whether the background is fully opaque . There s the RenderOptions.ClearTypeHint attached property that can be used to assure WPF that it s safe to use ClearType rendering in a certain subtree . This is what I used on my popup with an opaque background and a shadow around it . But it has no effect . The text always shows up with greyscale smoothing .

Answer : After a few days of searching I found an MSDN Forums thread http : social.technet.microsoft.com Forums en ieitprocurrentver thread 01c447b1-5c78-4d2f-9968-6eeabc04a68b which pointed me to a solution here : http : www.softwareninjas.ca dwrite-dll-wrapper .. . .. . Follow the instructions on that page and you ll remove anti-aliasing from IE9 at least the 32-bit version of IE which is the default IE even on 64-bit Windows 7 . I ve tested it so far on a Win7 x64 laptop and it worked flawlessly . Big thanks to Olivier Dagenais who built this . Here s a technical summary of how his solution works . It s a two-step process . First you need to disable ClearType in IE via a registry key . This is the same setting which was available in previous versions of IE but it was removed from the IE UI because it stopped working in IE9 . Second now that ClearType is disabled Windows will fall back to a non-cleartype anti-aliasing solution . Now that fallback anti-alising also needs to be disabled . Quoting from the thread above : .. . .. . What is left is the font smoothing aka sub-pixel rendering and that is the blurring effect you still see after turning cleartype off . .. . In case you were wondering there is a way to turn that off too . .. . The method i used to turn off the sub-pixel wonder is to build a simple wrapper for dwrite.dll which intercepts and forwards calls to the real dwrite.dll disabling font smoothing in the process . .. . You can download it from : http : www.softwareninjas.ca dwrite-dll-wrapper .. . .. . You can find the code at https : softwareninjas.kilnhg.com Repo Open-Source Group DWrite-dll-Wrapper .. . .. . This was a pretty cool hack . Probably somewhat brittle across windows and DirectX releases but will do the trick for now until Microsoft gets their act together to fix the underlying can t disable anti-aliasing problem in IE itself . It also works for apps which use the IE WebBrowser control aka MSHTML so you can control anti-aliasing on an app-by-app basis . It also works for the HTML Help viewer . Note that the text quality in IE9 standards mode isn t ideal . Specifically small fonts sometimes have letters sometimes run together without the usual one-pixel space between them . If you render the same page in compatibility-mode or your site uses a non-strict DTD or other non-standards-enforcing DTD then it looks fine . So there s an additional step for some sites if they want the best aliased text-rendering : just view a site in compatibility-mode by pressing the compatibility button in IE s toolbar .

In Windows on ARM WinRT ClearType is globally disabled .", "Question : So the new WPF 4 text-rendering looks great but enabling the aero-glass effect on a window requires that you change the background to transparent which of course disables ClearType rendering . Using the provided RenderOptions.ClearTypeHint Enabled allows you to designate child elements to reenable ClearType rendering from that point in the tree . I ve found a few other topics that talk about doing this for the ScrollViewer used internally inside RichTextBox and FlowDocumentScrollViewer and creating a custom style does indeed fix it so that my FlowDocument gets ClearType rendering again . However this only applies to top level paragraphs in the FlowDocument . If I add floaters or figures or a table any text inside them is inexplicably grayscale again . I know that the glass effect is to blame since disabling it reenables the ClearType rendering . I looked through the visual tree with Snoop but both the main content which renders properly and the sub-content which is grayscale have similar element hierarchies without anything to which I can attach RenderOptions.ClearTypeHint . Has anyone run into this problem Is there a workaround or a solution I checked Connect but there isn t any bug filed about this . It s quite an annoying problem . Comment : so you still have not found out a better way to do this I m kinda lost with this one and your accepted solution seems cumbersome . .. . Answer : After doing a lot more research and comparing the way different controls work on and off of aero-glass I ve found a few answers . The TextBox control doesn t work properly either but portions of FlowDocument and things like TextBlock do which prompted me to explore why . After digging around in reflector for a while I found that when using the advanced text formatting APIs to get text and render it onto a drawing context the RenderOption flags essentially go ignored since the drawing system knows from the root visual the window that transparency was enabled . Once that happens all the RenderOptions flags in the world aren t going to get ClearType back . I did happen to stumble on a work-around though . If you have access to the DrawingContext and are doing the low-level text-rendering yourself you can do a DrawRectangle behind the text with a fill and ClearType gets reenabled . I assume that this is the only way for the renderer to be sure that it has a proper background to draw on . So in summary you need to do your own text drawing and additionally you need to explicitly draw a background using the same DrawingContext behind your text in order for ClearType to get rendered properly .

The fonts are rendered in the browser . I notice that they are rendered with ClearType onto the screen and the letters in the words seem to be the same no matter where they are located on-screen although I have not checked many cases just some common cases . For example in the following image the letter a is repeated twice once at the beginning and nice later 3rd from the end . The letter a looks exactly the same pixel for pixel .

ClearType is here . http : en.wikipedia.org wiki ClearType .. . Answer : It might or it might not depending upon the font the size and which version of ClearType is in use and which application-settings are applied for rendering . Microsoft s http : msdn.microsoft.com en-us library ms749295 28v vs.85 29.aspx explanation of ClearType gets into this somewhat and even shows an example where you can observe a case where two instances of a character do not render the same see elle on the right both the e and l render differently in the second instance . This has to do with the use of fractional advance widths which get resolved to the nearest 1 64th of a pixel . Thus you could potentially end up with many different instances of a single character though as you can see the differences are fairly subtle . In short : I would not write anything that depends on any two instances of a character ending up exactly the same . They will be pretty similar but not identical .", "Question : I have a grid with this template and styles in WPF XAML : .. . .. .

There s nothing sub-pixel about it . What makes ClearType special and so colorful is that it uses sub-pixel rendering . .. . Answer : The reason this doesn t work and the reason you won t be able to get it to work has to do with ClearType s sensitivity to what it s rendering on top of . For ClearType to look correct it essentially needs to do per-component alpha blending . That is a separate alpha value for red green and blue normally alpha applies to all 3 . What this means is that ClearType absolutely must be rendered into a bitmap that is already opaque all alpha values are 255 you ll notice that window title bars still have ClearType but they use some super secret tricks to do this . The next step to understanding this is that WPF effects first render into an off-screen bitmap and are then combined with what s beneath in this case solid white or maybe blue if it s selected . So the text is first rendered into a clear transparent bitmap . Since it has no idea what will eventually be below it it must render using grayscale instead of ClearType . Then the effect is applied to that bitmap . Then the bitmap is drawn to where you expect it to be on-screen and there s no chance of getting ClearType even if it s on top of a solid color with no transparency . As a possible workaround try using 2 copies of the text . First apply the effect to the lower version of the text by lower I mean it should have a lower Z-index value and that is the case if it is first in the XAML . Then draw normal text on top of it which will get ClearType . I think this will work but I haven t tried it and you ll probably have to experiment until you get the desired visual outcome .

The question is : how do I enable ClearType for this text Comment : To my eyes it looks blurry because of the drop-shadow effect not because of the anti-aliasing style . Comment : @CodyGray Sorry but you are wrong . : It s blurry because ClearType is not being used . Comment : Hmm.. . Can you tell me what s wrong with my answer Comment : Pedantry : I wanted to point out that the text shadow rendering is just standard anti-aliasing like that used on Mac and Linux OS . There s nothing sub-pixel about it . What makes ClearType special and so colorful is that it uses sub-pixel rendering . .. . Answer : How about setting TextOptions.TextFormattingMode to Display as well as RenderOptions.BitmapScalingMode to NearestNeighbor The latter is new in WPF 3.5 SP1 and I normally use it to remove the blur . : .. . .. . Below is how it looks like . enter image description here http : i.stack.imgur.com UYQsz.png .. . .. . And this is how it looks like in FireFox . enter image description here http : i.stack.imgur.com 3r1H6.png Comment : Still slightly blurry although better . I ve come to conclusion that there s no solution . Workarounds look slightly better or worse depending on monitor and probably something else too . Comment : Really From the screenshots above the first one just looks crystal clear to me.. . I even tried a few monitors good and bad ones they all look pretty clear.. . Comment : This is how it looks after direct copy and paste : d.pr i 29CC http : d.pr i 29CC both in your screenshot and mine ClearType is not activated . For some reason on your computer it ClearType-less resulted in better quality . On my PC any ClearType-less text is mess . Firefox however uses ClearType and everything looks sharp . I chose the answer that said it s not possible because I ve come to the conclusion that it s not possible with WPF 4 . I ll hope this changes . Comment : I see I wonder what monitor you are using Comment : Here s a screenshot : d.pr i QXsL http : d.pr i QXsL the weird fuzziness goes away as soon as I take away the effect .", "Question : So the new WPF 4 text-rendering looks great but enabling the aero-glass effect on a window requires that you change the background to transparent which of course disables ClearType rendering . Using the provided RenderOptions.ClearTypeHint Enabled allows you to designate child elements to reenable ClearType rendering from that point in the tree . I ve found a few other topics that talk about doing this for the ScrollViewer used internally inside RichTextBox and FlowDocumentScrollViewer and creating a custom style does indeed fix it so that my FlowDocument gets ClearType rendering again . However this only applies to top level paragraphs in the FlowDocument . If I add floaters or figures or a table any text inside them is inexplicably grayscale again . I know that the glass effect is to blame since disabling it reenables the ClearType rendering . I looked through the visual tree with Snoop but both the main content which renders properly and the sub-content which is grayscale have similar element hierarchies without anything to which I can attach RenderOptions.ClearTypeHint . Has anyone run into this problem Is there a workaround or a solution I checked Connect but there isn t any bug filed about this . It s quite an annoying problem . Comment : so you still have not found out a better way to do this I m kinda lost with this one and your accepted solution seems cumbersome . .. . Answer : I know this could get tedious but have you tried setting general styles like so : Comment : It doesn t work .

Comment : Guys settle the negative height argument this BMP browser drop-in png jpg universal uncompressed replacement library ain t gonna write itself .. . Answer : Here s a quote from Petzold : .. . .. . So in DIBs the bottom row of the image is the first row of the file and the top row of the image is the last row in the file . This is called a bottom-up organization . Because this organization is counterintuitive you may ask why it s done this way . .. . Well it all goes back to the OS 2 Presentation Manager . Someone at IBM decided that all coordinate-systems in PM including those for windows graphics and bitmaps should be consistent . This provoked a debate : Most people including programmers who have worked with full-screen text programming or windowing environments think in terms of vertical coordinates that increase going down the screen . However hardcore computer graphics programmers approach the video display from a perspective that originates in the mathematics of analytic geometry . This involves a rectangular or Cartesian coordinate system where increasing vertical coordinates go up in space . .. . In short the mathematicians won . Everything in PM was saddled with a bottom-left origin including window coordinates . And that s how DIBs came to be this way .

I haven t been able to find a standard or typical way of doing this manually so I m wondering if there s perhaps a simple library that people use to load bitmaps into memory . Thanks in advance .. . Answer : You have 2 good options : .. . .. . 1 . Load and parse the BMP file yourself . BMP files start with a BITMAPFILEHADER followed by a BITMAPINFOHEADER followed by 0 or more RGBQUAD s palette entry . Offset to pixel data is in BITMAPFILEHADER but you should check BITMAPINFOHEADER to make sure the image format is what you expect support . 2 . Call LoadImage API with LR CREATEDIBSECTION flag it will return a handle to a DIB section . Next you call GetObject passing in the returned handle and a pointer to a DIBSECTION structure . Then you read DIBSECTION structure for bitmap size format pointer to pixel data etc . Option 2 is better if you re on Windows because presumably LoadImage checks for invalid file formats for you and can load more than just BMP files .

Answer : Note the code above is very slow . I ve found that to optimize the code above it s necessary to make a byte array to store all the data before you put it . Of course I was working in Xamarin C so maybe that s why . Anyway here s my Xamarin code in case anyone has the same problem . To use it here s the calling code : Comment : I m surprised that calling Array.Resize in the loop is faster than the original implementation I m not C expert . Suggestion : initialize final with it s target size before the loop . Comment : It wasn t Array.Resize that made it faster . The problem was all the .Put calls to the buffer . Changing those put calls to building up an array made the code take 2 seconds where as it was taking 13 seconds before . Comment : ok . my suggestion remains valid if you need to improve performance a little more . the java version don t have the same problem with the put Comment : Hey Ben75 . I m having a problem with this code . The file that s generated from the code looks perfect with the code as is . However when I print it . It s skewed . But when I change the BYTE PER PIXEL 4 instead of 3 it now reverses where the printing looks right on a O Neil spooler printer but the image is skewed the same amount . Have any ideas Comment : skewed image is probably caused by a wrong number of dummy bytes per row remember that bmp format requires that number of bytes per row is a multiple of 4 . If you change the number of byte per pixels then the computation of required dummy bytes can be broken", "Question : I have a weird thing in BMP GRAPHICS files . I create them with FULLSHOT 9 screen-capture software just mouse click+drag a rectangle on the screen and save-as .bmp FILE . When i watch the file in the binary editor i can see a pixel being use for a loooong time as expected . So you see something like this : .. . .. . editor shows 8 hex numbers per row Pixel 3 hex numbers like ED ED ED .. . .. . 0x00002f0 ---- some offset from start of file long past header part of bmp file after which i only expect a long sequence of pixels not some extra information .. . .. . But then suddenly you see a block of regular like Pixel 3 hex numbers but not repeating numbers .. . .. . i made the newline after each group of 3 for clarity... . the binary editor shows 8 hex numbers in a row .. . .. . i suspect these are not actual pixels but some information Then often you see a weird 0 alone . then the information part continues.. . .. . .. . and stops and a new looooong repetition of pixels .

QUESTION 1 : What could the meaning of this information part be QUESTION 2 : Is the zero really a terminator PS I have measured the difference between the reoccurring zero s and it usually is a multiple of with of the bitmap in different .bmp files i created and examined . .. . Answer : All the information you need is at Wikipedia on the BMP Format http : en.wikipedia.org wiki BMP file-format . 0x00002f0 ---- some offset from start of file long past header part of bmp file after which i only expect a long sequence of pixels not some extra information .. . .. . You don t mention at what position you find this value but that is probably the start of the raw pixel data : .. . .. . Bitmap File Header .. . .. . . . .. . .. . 000Ah 4 bytes the offset i.e . starting address of the byte where the bitmap image data pixel array can be found . Q1 . The information is from the looks of it just a palette . It is not required for a true color bitmap to contain an explicit palette but then again it may have one . Theoretically this would be an optimized 8-bit palette for the same image but I wouldn t count on it . The part you show is a simple list of grays . Q2 . Those zeroes may be DWORD line padding . They occur at multiples of bitmap width because each line in your image occupies in fact a multiple of the bitmap width bytes -- 3 times for RGB 4 times for RGBA . Only at the end of the line zeroes are inserted to make sure the next line starts at a DWORD boundary .", "Question : I could need some help to figure out how to feed the proc below .

I m now stuck on how to convert a std : : bitset or preferably boost : : dynamic bitset into this byte format . All of my attempts so far failed I wasn t able to write something like an 8x8 checker pattern into the BMP . The proc creates the BMP and it is readable by Photoshop but the content is a mess . So any suggestions how to solve this are appreciated -edit- .. . .. . an naive approach of mine was something like this .. . Answer : I have something very similiar.. . .. . .. . This approach DOES NOT treat the padding of the BMP format . So You can only make bitmaps with width multiple of 4 . This is NOT a monochromatic bitmap . It s a RGB format but you can tune it easily . This is NOT an exactly answer to you but for sure may be useful for you . Enjoy it . In this sample we want a white bitmap with a single black pixel at position X 2 Y 2 . The BMP format constiders that Y grows up from bottom to top . If you have a bitmap width a pixel per bit the real monochromatic bitmap you can test the bits and fill the imageData . To test a bit in a byte do like myByte position 1 where position is the bit you wanna test from 0 to 7 . Comment : Thanks for reply but whit this code my exact problem remains : how to fill the byte array Whats the representation of the color WHITE and BLACK inside the bitmap expressed as byte type I tried values like 0 0x00 1 0xff - everything failed . Can you create an byte example for a 4x4 b w checker pattern for your code Comment : sure.. . hold on - Comment : In my sample every 3 bytes represents RGB channels.. . if I set them as R G B we get a monochromatic image . I can t know exactly your sample because I can t know the input bitmap format to get the bits from.. . But basically This is what you need . Comment : Ok but what is an exact value for R G B in your case byte rgb 16 rgb 0 .. . Comment : You mean the pixel position I can show it to you.. . hold on", "Question : sorry if this question is silly i m just starting with C .. . .. . I have an image in disk which I know the path .

I need to load it in the code and resize it since the progam dies if I try to put in a picture box 400m of image but if I do .. . .. . But when I do Bitmap b0 new Bitmap pathImage it just dies since 20000x10000x32 it s too much for my poor memory . The problem is that if not specified c just uses as pixel format Format32bppArgb but I want Format1bppIndexed and the only way i ve found to change the format is with the constructor .. . .. . Bitmap int width int height int stride PixelFormat format IntPtr scan0 .. . .. . But for this constructor I need to know the size of the image which in the code I don t know because it dies before the code can get it and know the size.. . I m lost . Any ideas EDIT : Doing this int width .. . .. . I get the size of the image I cannot load and can create a bitmap with the pixelformat and size that i wanted BUT everyway I try to upload it doesn t work it still crashes on me . I ve tried using graphics .draw tiff.. . and tiff.getThumbnail new size.. . and it just dies on me . It targets x86 and the .Net 3.5 since those are the requirements of the client.. . .. . .. . Any ideas Comment : You are completely on the wrong track with this . There s just no conceivable reason left to not run this kind of code on a 64-bit operating-system . Change the Platform target setting to AnyCPU . Comment : The program uses some dlls and exes that are for x86 so i was compiling for 32 bits not my choice my boss choice but I had not though it may be because of that .

Answer : If FileStream works to open the file you might want to give some of the other constructors of Bitmap a try in particular Bitmap Stream http : msdn.microsoft.com en-us library z7ha67kw 28v vs.110 29.aspx . If that doesn t help you might try loading the raw bmp data creating a Bitmap with the format you want and copying the data into the Bitmap manually I m not familiar with C Bitmaps but there should be some way of accessing the data .

Answer : biXPelsPermeter Specifies the horizontal print resolution in pixels per meter of the target device for the bitmap . biYPelsPermeter Specifies the vertical print resolution .

So in this case-when you copy the data in it is filling in the left over bits as black . the bitmap is 154 bytes wide which creates 19 full bytes and 2 left over pixels .

In the end you need to use bitmaps with widths that are divisible by eight or make sure the end of the data copy from the bitmap to pixels x accounts for the remaining bytes .", "Question : my code to save bmp format : .. . .. .

Comment : i am sorry the image is 1mb 1.048.630bytes not 10mb so if i use this code System.Drawing.Imaging.ImageFormat.Bmp it will automatically save a 32bit bmp .. . Answer : BMP is a very simple image file-format . Just a little header that describes the image-size pixel format resolution color table followed by a blob of pixel data . Technically it can be compressed with RLE but encoders don t bother anymore . The pixel data depends on the pixel format ancient ones are 1bpp 4bpp and 8bpp they require a color table . 16bpp can happen unusual normal ones are 24bpp RGB and 32bpp ARGB . In other words 3 or 4 bytes per pixel . So yes 512 x 512 x 4 1 megabyte . MSPaint is pretty explicit about the pixel format it uses . It is a very simple painting program without support for alpha blending effects . So uses 24bpp no alpha 512 x 512 x 3 786 kilobytes . You could use Paint.NET to create 32bpp BMPs . Which one you get in your own program depends on how you created the Bitmap object . The simple version uses the same pixel format as the video adapter . On all modern machines that s 32bpp . 16bpp can happen it is very unusual . If you want another format then you have to use the Bitmap constructor https : msdn.microsoft.com en-us library 3z132tat 28v vs.110 29.aspx that takes a PixelFormat argument . There s otherwise a pretty good reason to do this the default pixel format is not usually the most optimal one . The best one by a factor of 10 is the format that matches the pixel format of the video adapter exactly . Choice is between 32bppArgb and 32bppPArgb . The P means pre-multiplied the alpha value is applied to the RGB values up front . Argb is most efficient if you do a lot of drawing into the bitmap yourself with Graphics.FromImage . PArgb is most efficient for painting the pixel data can be blitted to the video frame buffer directly without having to be converted . Ten times faster . You usually care about painting speed the most visible artifact of a program . If you care about image file size then there is no better choice than PNG . It compresses the pixel data with LZW compression typical compression rates are 50 or better . JPEG is a decent choice as well much higher compression rates but it is lossy . It achieves high rates by throwing away image details . Suitable for photos in general images without text or line art that don t otherwise have to be compressed multiple times .", "Question : How can I read the color value of 24bit BMP images at all the pixel h w in C or C++ on Windows better without any 3rd party library .

It is easier to read uncompressed 24-bit BMP files . They just contain a header at the beginning and RGB values of each pixel . To start with this check the example of 2x2 bitmap image at http : en.wikipedia.org wiki BMP 5Ffile 5Fformat . Follow the below steps . 1 . Create the 2x2 BMP image shown on Wikipedia . 2 . Open the file in binary mode using your C program . 3 . Seek to byte position 54 . 4 . Read 3 bytes . The bytes would be 0 0 and 255 respectively . Not sure whether the order is RGB . I had done this long back and I think the order is not RGB . Just verify this .

Answer : There s some example code here http : www.java2s.com Code Java 2D-Graphics-GUI ListAllreaderandwriterformatssupportedbyImageIO.htm that will enumerate supported image-formats by your JDK . BMP is supported by the advanced image toolkit http : www.oracle.com technetwork java release-jai-imageio-1-0-01-140367.html but I know that it also has things in it that are now supported by the base JDK too . So if its supported by both then maybe the JAI support is more comprehensive . That seems unlikely though as it doesn t make much sense . OTOH it was Sun . If you re using JDK 6 you can definitely do PNG which is more portable can you convert your images IIRC MS Paint will save a png . Comment : the image-formats claimed to be supported by the ImageIO reader s are highly misleading as explained in my lenghty answer : If BMP was really supported the OP could open his image using ImageIO just as he can open it from MS Paint .

This has nothing to do with client WinSCP as it cannot even know it s a junction . Your SFTP server most likely simply presents the junction as a folder . Although it could also present it as a symlink to a folder but in that case WinSCP would silently skip it . Side note : All methods of WinSCP .NET assembly accept only absolute paths . You should not rely on using . Also path to remote target directory should end with slash .

WinSCPnet.dll was loaded but DllRegisterServer entry-point could not be found . Does anyone have any idea why it s failing I have also asked the author of the DLL and he s leaning toward a Dolphin problem since the registration worked in Windows . .. .

EDIT : Your WinSCP forums notion in order to use it within dolphin you need to have its tools register the dll and tlib is wrong you are doing too much importing for this case anyways in ordinary cases this might not matter . Normally import EITHER .DLL if it s COM .dll with embedded type info OR the .TLB . So if there is .TLB I d go for .TLB otherwise try my luck with .DLL . Sadly for some standard COM interfaces Microsoft never made typelibs available so it s even worse there use C C++ or create structs interface tables by hand .

Dolphin creates smalltalk classes to mirror the COM types structures . You use these to instantiate COM types from Smalltalk call their methods pass them and also primitive-types such as strings integers .. . as arguments and get Smalltalk types for returned values Dolphin does all the conversions for you so you can +- forget you are calling foreign code . 2 an example of the method you implemented mapping the library class to the winscp interface . I implemented nothing I just used the generated wrapper in background WinSCP COM object - SessionOptions - got created and had some properties set . basically i just said : .. . .. . Just look at WinSCP Automation documentation examples and then convert it to smalltalk-speak and hopefully it should auto-magically work - . 3 where are the smalltalk methods protocol : hostName : etc defined i searched the image and they are not there . how did you know to use those method names Since SessionOptions represented by PREFIX SessionOptions class in Dolphin is an IDispatch interface subclass of IDispatch in Dolphin all the method calls are dynamic in nature . You just do the right things catch possible failures at necessary granularity and it will just work tm . Smalltalk sibbling is the doesNotUnderstand : aMessage method .

I assume you did not enable setting permissions it s off by default . If you did turn it off by setting the TransferOptions.FilePermissions https : winscp.net eng docs library transferoptions filepermissions see below . Your server probably does not support updating timestamps of remote file . That makes it complicated to allow local-to-remote synchronization of files against such server as the timestamps are primary criteria https : winscp.net eng docs ui synchronize criteria to compare the files . In general it does not make sense to turn off updating timestamp with synchronization as the update is basically an integral part of the synchronization . The hint to Ignore permission errors is there for basic file transfers . As mentioned already it does not make sense for synchronization . So all you can to is to : .. . .. . turn off updating the timestamps set TransferOptions.PreserveTimestamp https : winscp.net eng docs library transferoptions filepermissions .. . .. . and make WinSCP not consider the timestamps when comparing files set criteria parameter https : winscp.net eng docs library session synchronizedirectories criteria of Session.SynchronizeDirectories https : winscp.net eng docs library session synchronizedirectories to WinSCP.SynchronizationCriteria : : Size or None . It s questionable though how such synchronization is meaningful . Comment : Martin many thanks . Your code update worked for me . A question though why you think such synchronization may not be meaningful Comment : Well synchronizing based on file size is not very reliable .

I ve read this tutorial http : www.sencha.com blog an-introduction-to-theming-sencha-touch as well as some others . Am I missing something .. . Answer : You should really look at Saas and Compass nevertheless you will always have to override some css by hand because not all variables are yet defined in Sencha Touch . So some colors and other properties cannot be changed by modifying Sencha sass variables . Anyway you should use sass so that your custom css code is located in your app.scss file and this will be compiled to the app.css . So you do not need to add any other .css file in your app structure . And then you can add your own var to easily customize your own look .

Answer : You can ofcourse go and modify the CSS and replace all the colors you need since Compass SASS just compile to CSS . I would have to disagree with you though on that it s ludicrous . The base theme color is used in many different places and there are various gradient rules applied to it that Compass SASS generates .

Answer : If you re already using Sencha Architect theming is built right in if you re using the latest version . See this post http : www.sencha.com blog re-skinning-your-apps-just-got-easier-with-sencha-architect-3 from the Sencha blog . Comment : Thanks for the response . Yes we have default themes in Sencha Architect like DefaultTheme BlackBerry MountainView . I would like to create theme like default themes with respect to my company standards which will be used in all my sencha app . Is this possible Comment : Right click on your theme and hit export to file which creates an XDC file . Then you can select EDIT IMPORT COMPONENT and import that XDC file in other projects . Comment : thanks for the help .", "Question : I have a fast question that I hope some1 can answer me . I am implementing custom design for a company doing a sencha-touch app for ios and android . When I first came it was a big mess of importants and overrides everywhere and i couldnt touch Anything without having to backtrack stuff for 10minutes before I could set a property . Now we have a new project with supercusom design and I am seriously thinking of excluding as much as possible and maby even everything of senchas sass css files except for maby loading-spinner or something like that . Or do you recomand to keep at least some of the sencha widgets Because I dont wanna mess up sencha logic either . thanx Comment : I don t quite understand.. . Where is the custom CSS code that is the mess Did someone actually merge it in all over the ST debug css file If you are scrapping everything anyway for the new project why not just start over again with the base ST CSS or custom SASS build of it Comment : Also ST2.2 beta is out there if you an wait for the final release I know there will be some significant theming changes - including a barebones stylesheet that has only the absolute necessities for the components to render in the right spots and function correctly everything shows up as simply blank boxes with text . .. . Answer : Many of the properties of Sencha components are tied to sass functions or specific css . For instance layouts and layout types will be translated to css at runtime . I ve found that if you are going to use the Sencha framework it is much easier to follow the paths they provide for customization like the cls properties they include baseCls innerCls cls inputCls etc . then to simply override all of their x-type classes or use important . I would recommend you keep the sencha widgets and provide your own sass css within these cls properties .", "Question : I m trying to make my own custom theme for this I import the Base theme .

All documentation on the internet says that we had to add the cls : CustomClass item and add the class to the app.css file . Alle other classes in that file are working problerly . So it cannot be the css file . We did instead it isn t working we still see the default layout . Might anybody be able to help List definition : .. . Answer : Are you adding the css to resources css app.css file Then when you test are you using Sencha CMD Maybe running sencha app watch or sencha app build commands before testing your change If so during the build the app does a compass compile and recreates the app.css file from the MyApp resources sass app.scss file . Anything you write in the .css file that has a matching sass scss file will be over written . You may want to include a css file that can be in the css folder but you name it uniquely . Maybe call it overrides.css . Now you need to let the app know about the css file . For that you can add it to the head of the index.html file but I would recommend adding it in the MyApp app.json file around line 73 . Make sure your css loads after app.css by placing it after the app.css reference . Once you clear your cache and refresh you should hopefully see your changes . If your css doesn t override Sencha s you may need to target the dom item more specifically . Sencha generates an ID for almost every element . I don t recommend using those because they can change between projects .", "Question : I want a custom toolbar with background-color as gradient . I tried with sass . But still it is not working. .

I have ported the iOS7 iBeacon SDKs to Android and was able to see standard iBeacons and estimate their range .

You also need a device with a low energy bluetooth chipset . If you don t want to use the full library above you can roll your own . iBeacons simply transmit a BLE advertisement once per second that start with a known sequence of bytes . You simply have to tell Android to do a BLE scan get each advertisement and look for one that starts with the known iBeacon byte sequence . You can then parse out the iBeacon fields .

Comment : No the Samsung BLE SDK is a completely different implementation than the one native to Android 4.3 . In theory it would be possible to create a version of the Android iBeacon Library that works with Samsung BLE SDK but it would involve rewriting much of it . Given that most if not all Samsung devices with BLE will probably get an upgrade to Android 4.3 in the next several months it just isn t worth the effort to port the Android iBeacon Library for the Samsung BLE SDK . Comment : @MarkPeterson very interested to know if you are able to get it to work with earlier versions . Comment : Do you know if it is possible to look for beacons in the background like you can do in iOS 7 Comment : For @MarkPeterson and others looking for support on Samsung devices runing 4.2.x this is now possible . See here : github.com davidgyoung android-beacon-library tree https : github.com davidgyoung android-beacon-library tree samsung-ble-sdk", "Question : I was trying to implement beacon scanning program and i want the android BLE services to behave similar to iOS didRangeBeacons method i.e it should get called every one second . But in android there is no such method . But in android there is leScanCallback method that gets called very frequently with a scan period of less than a second . So is there any way that i can implement my functionality in leScanCallback method and increase its scan period interval to 1 second so that it behaves similar to iOS s didRangeBeacons method . Also will it be the bad programming to continually scan beacon and increasing its scan interval in android Thanks in advance .. . Answer : It is important to understand that there is no native iBeacon support in Android . The Android leScanCallback method is not at all an equivalent of the iOS didRangeBeacons method . The leScanCallback method simply gives you a callback every time an advertising packet from a Bluetooth device is seen devices with the connectable bit set in the advertisement are only given a callback the first time its Mac address is seen until you stop and restart scanning . Unless you stop and restart scanning on a timer there is no scan period and you get callbacks as the packets arrive . This can be many times a second . When writing the open-source Android iBeacon Library http : developer.radiusnetworks.com ibeacon-android I had to build all the functionality from scratch to make a didRangeBeaconsInRegion callback that was the equivalent to what is in iOS . To do this the library stops and restarts scanning about once a second and buffers the list of all iBeacons seen in the cycle only calling the callback with the list of visible iBeacons at the end of the cycle . There are lots of other complexities not discussed here . The code is free https : github.com RadiusNetworks android-ibeacon-service for you to review and modify so I encourage you to do so if you want to roll your own . Comment : Thanks David . I was reviewing the code written by you . Its really nice work . And now I got the logic behind scanning . : Comment : If we want to scan only when the application is in foreground and not in background.What will be better Scanning continously or scanning in an interval of say 1 sec Comment : You must scan at an interval . Many Android devices have a bluetooth hardware layer that only provides only a single detection callback per detected hardware device per scan . Stopping and restarting is needed to get a second callback for the same hardware device . Comment : If we are not scanning in the background should we use BluetoothCrashResolver as the lib says It is rare for most users but can be problematic for those with apps scanning for Bluetooth LE devices in the background .

Unlike iOS7 it is not natively support . In iOS7 when you on your BT it will automatically notify you when you enter the region of registered iBeacon . I had implemented iBeacon in Android 4.3 API using IntentService plus AlarmManager . To do a scan every 30 sec to save your battery power it shall be longer . It works well for user .

You can also transmit as a beacon on rooted Android 4.4.3 devices http : stackoverflow.com questions 34424479 can-an-android-4-4-device-act-as-an-ibeacon but it requires an app installed with system privileges . For older OS versions continue reading . Android 4.3 devices with BluetoothLE can see iBeacons but not act as iBeacons because Android 4.3 does not support peripheral mode . Samsung Android devices contain a separate proprietary SDK but it also does not allow devices to act as iBeacons . See : Make Samsung Android device advertise as an iBeacon http : stackoverflow.com questions 20312892 make-samsung-android-device-advertise-as-an-ibeacon iOS devices however can act as iBeacons . Normally iBeacon technologies are not intended for phones to see other phones . But you could do what you suggest on iOS by making a custom app that makes phones act as an iBeacon and look for other iBeacons around them . This would allow anybody with the app to see others with the same app nearby . All phones would need Bluetooth turned on . strike Doing this on Android would currently only be possible with Samsung devices . strike .. . .. . To answer your second question yes a mobile device both Android or iOS must have an app installed to take advantage of iBeacons . Neither operating-system currently does anything when it sees an iBeacon unless an app is installed that is specifically programmed to do something . So customers who arrive in a store must have an app already installed or they cannot interact with iBeacons .

This is the first time I tested outside Nexus . Did anyone test BLE scanning on Huawei Ascend Mate2 Any observations and comments would be appreciated . Huawei Ascend Mate2 : Device model number is MT2L03 and Android version is 5.1 .. . Answer : I worked with a lot of different devices and I can tell you that the behaviour is very different on different devices . I don t have an Huawei Mate2 but I could observe similar behaviour where you only get a scan result once per device . So if you need to have multiple scan result for the same device you need to restart the scan from time to time .

Answer : EDIT : There is now a partial solution for this here . http : developer.radiusnetworks.com 2014 04 02 a-solution-for-android-bluetooth-crashes.html .. . .. . The good news is that this low-level Android bug largely affects developers or people who work in Bluetooth dev shops who have been around a large number of Bluetooth devices in the same place . Going to a BLE or iBeacon hackathon will almost certainly a trigger it . Fortunately most end users of our apps do not do this . The bug is triggered when an internal buffer holding recently scanned Bluetooth LE Mac addresses fills up . After it fills scanning a new Bluetooth LE device will cause Android s Bluetooth service to crash and restart itself . The dialog you see is from Android s Bluetooth Share service which dies not cleanly handle the restart of the Bluetooth Service restart and crashes itself . Here is the Android bug report . https : code.google.com p android issues detail id 67272 .. . .. . The bug can affect any app or library that does Bluetooth LE scanning or looks for iBeacons not just the Android iBeacon Library . But again not all users will experience it . I work at Radius Networks where we have dozens of Bluetooth LE devices transmitting all the time and it took four months before I ever saw that dialog on my Nexus 4 -- it only came up two weeks ago . Since then I have been working to characterize the problem and find workarounds . I have been able to clear the condition simply by going into Airplane Mode for a few seconds then coming out . This however is not a permenant fix as overflowing Android s buffer again will cause it to return . We are still researching more automated solutions . Comment : My Nexus 5 got this problem without being exposed to more than four beacons . Additionally it was fine earlier this morning and the error simple began occuring while I was testing with only those four beacons near . There has to be more to this story . Comment : If the beacons rotate their mac addresses e.g . Gimbal beacons then even a single beacon can cause this condition because each mac address appears to android as a different device . Comment : Thanks David These are estimote beacons so no rotating mac addresses . Comment : It could be that your mac address table is already full in the Bluedroid stack from being around a large number of devices or a smaller number with rotating macs at an earlier time .

I have stumbled upon Android iBeacon Library samples http : developer.radiusnetworks.com ibeacon-android samples.html and gave it a try . I used the latest aar file 0.7.3 and basically copy-paste their examples in a new project . I have created a beacon using an iPad with AirLocate compiled from Apple s code from the Dev Center and launch the code . My problem is the range fluctuating all the time with no logic . For example the phone in this case a Nexus 5 original rom no modification placed half a meter away from the iPad gives me the following measures : .. . .. . 0.01m .. . 0.03m .. . 0.07m .. . 0.48m .. . 0.01m .. . 0.02m .. . .. . etc . When I use another iPad with AirLocate on it it gives a more stable and realistic measure . Excluding the beacon as the source of the problem . I have made the test with a Nexus 7 2013 Original rom not modified and I got the same issue . I have read the wifi can cause problem so I disabled it but it is still the same . I also have the same issue with Radius Networks application on the Play Store : iBeacon Locate https : play.google.com store apps details id com.radiusnetworks.ibeaconlocate hl en .. . .. . I was wondering if the anyone else have the problem with this library Is there something I can do to help fix this problem Do you know another library I can use which won t cause that kind of problem Any help is appreciate . Thank you in advance . .. . Answer : A big part of the variation you see is Android is caused by a limitation in the way Android allows access signal strength measurements from Bluetooth LE . Unfortunately there isn t much that can be done about this without changes to Android . In both iOS CoreLocation and the Android iBeacon Library the distance estimate is only an estimate and fluctuations with noise on signal strength measurements cause the estimates to bounce around . The algorithm in the Android iBeacon Library is not the same as in iOS CoreLocation because the iOS CoreLocation implementation is closed source . The intention is that they behave in a similar way . The Android iBeacon Library is based on a 10 second running average of 80th percentile measurements e.g . the top and bottom 10th percentile measurements are thrown away for the average . You can see the details of the calculation here : .. . .. . On Android the Bluetooth LE Scan API only allows a single signal strength measurement per scan . On iOS it is possible to get a different measurement for each advertisement broadcasted . By default the Android iBeacon Library does one bluetooth scan every 1.1 seconds when it is in the foreground therefore allowing one measurement every 1.1 seconds . So if you have an iBeacon that is transmitting 30 times per second as iOS devices acting as iBeacons do iOS will be able to get 300 samples in a 10 second period and Android only 9 . This explains why the estimate has higher noise on Android . And again there is very little that can be done about it without operating-system changes . Depending on your use-case you may be able to reduce the noise in the distance estimate on Android by implementing a custom calculation that includes more samples over a longer period of time . This would only be appropriate if your use-case does not need rapid updates in the estimate . If you are interested in this you might open a feature request https : github.com RadiusNetworks android-ibeacon-service issues page 1 state open in the open-source library . Comment : Thank you for your answer this makes it a bit more clear about what is going on . Yet when I go further with my devices let s say 10m away I ve got very big variations from 1m to 20m measured . Is that normal Should I have such important variation Comment : Sorry for double commenting this I cannot edit my last comment . For your information here is a graph of the accuracy over time I was standing still with my Nexus 5 3 meters away from the ipad-mini broadcasting as an ibeacon . imgur.com dG7NYi2 http : imgur.com dG7NYi2 Comment : It is normal for variation to increase with distance . The graph does look like a little more variation than I typically see at 3m but this could be caused by reflections in your test location or other factors . If you want to drill into this more also plot the rssi alongside the distance from iBeacon.getRssi . Comment : Great answer thanks @davidgyoung . We d seen this issue with both yours and Estimote s Android SDKs and assumed it must ve been something to do with how Android surfaces the RSSI . Really good clarification .

Answer : The Android OS does not have any code that detects iBeacons but it does have code that allows you to scan for Bluetooth LE devices which are a lower-level device than an iBeacon . You can roll-your own code that detects iBeacons using this Bluetooth LE scanning . That s exactly what the Android iBeacon Library http : developer.radiusnetworks.com ibeacon-android from Radius Networks http : www.radiusnetworks.com does . It is open-source so if you don t want to use the library you can simply copy blocks of code out of the library and do your own detection .

EDIT : the library has been moved to http : github.com AltBeacon android-beacon-library .. . .. . If you detection use cases are very simple this might work fine . Be careful not to bite off too much work though because handling all the edge cases can become increasingly complex . That s certainly what I learned when writing the library . If you just want to play with this I would focus on one class from the library : IBeacon.java https : github.com vmagro android-ibeacon-service blob master src main java com radiusnetworks ibeacon IBeacon.java .. . .. . This class can convert from an Android Blueooth LE scan record to an IBeacon if the scanned Bluetooth device is indeed an iBeacon .. . .. .

The NOT SUPPORTED CANNOT GET ADVERTISER MULTIPLE ADVERTISEMENTS NOT SUPPORTED MULTIPLE ADVERTISEMENTS and NOT SUPPORTED CANNOT GET ADVERTISER return typically indicates that the device either does not have a compatible chipset or the manufacturer has not implemented the driver support required by Google for the Android 5.x BLE transmission APIs .", "Question : My Understand for iBeacon : Beacons are scan using by UUID in iOS . But in Android able to scan without UUID . Clarification : I have searched more things in internet and stack-overflow for beacons are scan without uuid . But most of them said must have UUID to scan the beacon in iOS . But all of them in before 2015 . I don t knw right now 2016 apple update anything do scan without UUID . Android able to scan without UUID . Please any one confirm beacons are scan based on UUID using by ibeacon in iOS . Each application have only one UUID for all beacons . We define the differences the beacons in major and minor values . If i set UUID for multiple beacons able to search in iOS using by ibeacon Below reference link counld t to without UUID . Any possible way is there for scan without UUID Ref : http : www.ibeacon.com what-is-ibeacon-a-guide-to-beacons .. . .. . https : developer.apple.com ibeacon Getting-Started-with-iBeacon.pdf .. . Answer : On iOS you must know the ProximityUUID of a beacon in advance in order to scan for it using CoreLocation . This has not changed since iBeacon was announced by Apple three years ago . You must know this because the CoreLication scanning APIs require you to specify the UUID to look for when starting beacon ranging or monitoring . It may not be left nil or wildcarded with public APIs . This restriction does not apply to other beacon formats like AltBeacon and Eddystone whose full identifiers can be read without knowing any part of them in advance . This is possible with these beacon formats because they use CoreBluetooth to do the scanning not CoreLocation . CoreLocation is what requires the UUID up front and Apple blocks iBeacon scanning with CoreBluetooth . Comment : Thanks for your information Davidgyoung. .

I am keeping Major and Minor for uniquely identifying the beacons . Since my application has to be in background I am using BeaconManager.MonitoringListener interface with onEnteredRegion and onExitedRegion callbacks My understanding is Ranging can only be done when application is in foreground . Since onExitedRegion does not provide me any List of beacons that triggered onExitedRegion how can I get beacon details like Major Minor in onExitedRegion .. . Answer : EDIT : The library mentioned below has been replaced by the Android Beacon Library http : altbeacon.github.io android-beacon-library . Code samples are available on the same site . .. . .. . You do not say what library you are using but the open-source Android iBeacon Library http : developer.radiusnetworks.com ibeacon-android allows you to do this by combining ranging and monitoring . The library has no restriction on using ranging in the background unlike iOS . The library is fully compatible with any standard iBeacon . Although the library s didExitRegion callback does not tell you the specific beacon that disappeared you can keep track of these visible beacons based on the list passed to you in the most recent didRangeBeaconsInRegion callback . That way when you get the didExitRegion callback you know which beacons were last visible before they all disappeared . Samples of both ranging and monitoring code are available here http : developer.radiusnetworks.com ibeacon-android samples.html . Comment : Thanks a ton I did mentioned the library i am using i am working on Estimote library . Can you please share a sample code how we can combine ranging and monitoring in android using estimote library . or should i use open-source library . A sample code will be very helpful . Comment : Got it . I read that you were using Estimote beacons which are iBeacon compatible so they do work with the Android iBeacon Library . See edits for links to sample code of ranging and monitoring . Comment : Thanks for the code . I ll try and keep you posted . Comment : I have tried your suggestion of combining ranging and monitoring . My scenario is : I am doing ranging first . It is giving me list of beacons in range . Then in onBeaconsDiscovered i am creating a Region for all the beacons that i have discovered . Then I start monitoring that region . It will give me callbacks for onEnteredRegion and onExitedRegion . Problem is sometimes same beacon is entering twice in onEnteredRegion without exiting . I have tried to play around with scan interval for foreground and background scan but things not in sync . Comment : I d probably have to see your code that sets up these monitored regions upon ranging to make more suggestions . It is possible to have overlapping regions e.g . if two regions have the same ProximityUUID that would cause the behavior you describe .", "Question : I start working with ibeacon and android .

Althougth discoverServices return true but there is not any callback execute I hope onServicesDiscovered being called but not . Status is 133 and newstate is connected . Does status make it fail to get callback Comment : the 0x85 as status indicates an error and thus you should figure out why you are getting it and then it should work fine Comment : Please note the manufacturer and model of iBeacon you are using . Not all iBeacon implementations support GATT services so it may be that you are not supposed to be able to connect . .. . Answer : More information would be helpful can you supply the received Advertisement data The following is just a guess as theres a broad range of issues around with Android BLE however i seen this general 133 error already when accidentally issuing a BR EDR connection to a Beacon . As Android defaults to a BR EDR connection when the GATT-server device advertises support for it you can try to explicitely set the transport to TRANSPORT LE in connectGatt however since this parameter is only aviable in the hidden version of it you need to use reflection . Try to issue the connection like this : .. . .. . That way you can at least be sure its not related to this Android behaviour .", "Question : Short version : .. . .. .

Answer : I have experienced very similar results with my Nexus 4 in both KitKat and Lollipop . With KitKat the bluetooth adapter also eventually went unresponsive at first I though that it could be related to a short scan interval 200ms but increasing that number to even a second didn t help in that matter I found that when unresponsive disabling and enabling the adapter programmatically sometimes solves the problem . Unfortunately I can t say that it works all the time . Now with Lollipop in which I had high hopes to solve this issues I experienced the same behaviour that you describe . I also had to use the startScan stopScan implementation getting similar results regarding the detection times . Sadly I haven t found a work around to get results more quickly . Based on what you describe I suppose it could be a hardware issue even though the Nexus 7 and Nexus 4 are from different manufacturers Asus and LG . I know I m not providing much help here besides trying to answer your question about you missing something I don t think so I think the problem is something like the hardware or the bluetooth API that still doesn t behave the way it should across different devices .

Answer : if you search for BW13 DayOne Session1 Bluetooth Advanced on google you will find a pdf document that gives you the latencies for devices based on the settings for discovery see page 8 . I m guessing your problem has to do with these timings .

Also tried with instantclient version 10.2 .. . .. . Could someone help me figuring out what the problem might be and how to solve it Any help is really appreciated . Thank you Comment : Exactly what version of 8i are you trying to connect to The requirements for 8.1.5 for example are rather different than the requirements for 8.1.7.4 . Oracle doesn t generally make obsolete versions of products available for download so you can t download the 9.2 client libraries any longer . If you have a support contract you can log a Metalink support request and Oracle support can get you the old libraries . Of course those old libraries may require a rather old version of linux . Comment : @JustinCave the version is 8.1.7.4.0 . I m updating my question . I will try to find a way to download 9.2 client libraries . This is the instantclient libraries correct Thanks so much for the answer . I really appreciate Comment : I m not sure that the Instant Client existed back in the Oracle 9.2 days . My guess is that you d need the full Oracle client install which is a few hundred MB . If you ve got a support contract Oracle Support can send you obsolete software on CD . It s reasonably likely though that the Oracle 9.2 client won t be compatible with whatever version of linux you have and that you d have to downgrade to an older version .", "Question : I want to connect to my oracle database but i have a problem with function oci connect . i have tried to uncomment this : .. . .. . but still have an error : .. . .. .

Answer : The main problem is you make confusion between queries supposed to be executed on server-side and sqlplus commands to be executed on client-side . The define and @ commands are sqlplus commands executed on client-side . They are not sent to Oracle . With the oci8 module Ruby can connect to Oracle using OCI . It can send any query to the server but of course it will not be able to run sqlplus commands . The scripts in rdbms admin are supposed to be executed from sqlplus . If you really need to run them from Ruby I would suggest to use the Ruby Open3 http : www.ruby-doc.org stdlib-1.9.3 libdoc open3 rdoc Open3.html module to fork a sqlplus process and provide the input parameters using pipes . It should be possible to use something based on the following code : Comment : Thanks a lot I am clear where am i wrong now .

Answer : I presume you are aware of these facts : .. . .. . There are many different character sets : you have to pick one and of course know which one you are using . Oracle is perfectly capable of storing text without HTML entities eacute . HTML entities are used in well HTML . Oracle is not a web browser - .. . .. . You must also know that HTML entities are not bind to a specific charset on the contrary they re used to represent characters in a charset-independent context . You indistinctly talk about ISO-8859-1 and UTF-8 . What charset do you want to use ISO-8859-1 is easy to use but it can only store text in some latin languages such as Spanish and it lacks some common chars like the symbol . UTF-8 is trickier to use but it can store all characters defined by the Unicode consortium which include everything you ll ever need . Once you ve taken the decision you must configure Oracle to hold data in such charset and choose an appropriate column type . E.g . VARCHAR2 is fine for plain ASCII NVARCHAR2 is good for UTF-8 . Comment : Thx for the reply . The Oracle database that I am using is using ISO-8859-1 I can not change that .

What is the right way to set environment-variables for servers launched with Thin The solution here http : stackoverflow.com questions 10294815 getting-thin-to-read-configured-user-environment doesn t work because I can t give ruby-oci8 the information it automatically reads them from the environment . Comment : So you have somewhere in your code ENV TNS ADMIN and for some reason this env variable isn t accessible or quite right when using Thin so the connection fails The command looks slighty wrong shouldn t it be bundle exec thin start -C config thin.yml -R config config.ru On a side note I heartily recommend using bundle install --binstubs and then you can use bin thin or whichever command instead .

Answer : The goal of InputStream and OutputStream is to abstract different ways to input and output : whether the stream is a file a web page or the screen shouldn t matter . All that matters is that you receive information from the stream or send information into that stream . InputStream is used for many things that you read from .

An explanation with some code snippet will be great . I just need to figure out their difference and usage . .. . Answer : OutputStream is an abstract-class that represents writing output . There are many different OutputStream classes and they write out to certain things like the screen or Files or byte arrays or network connections or etc .

When someone writes into an OutputStream it becomes available for someone else to use in an InputStream . This is basically what PipedOutputStream PipedInputStream do . Unfortunately the Piped streams can t be built from other streams . Comment : so the PipedOutputStream PipedInputStream is the solution Comment : Basically in order for PipedStreams to work in your case your OutputStream would need to be constructed like new YourOutputStream thePipedOutputStream and new YourInputStream thePipedInputStream which probably is not the way your stream works . So I don t think this is the solution . .. . Answer : If you want to make an OutputStream from an InputStream there is one basic problem . A method writing to an OutputStream blocks until it is done . So the result is available when the writing method is finished . This has 2 consequences : .. . .. . 1 . If you use only one thread you need to wait until everything is written so you need to store the stream s data in memory or disk . 2 . If you want to access the data before it is finished you need a second thread . Variant 1 can be implemented using byte arrays or filed . Variant 1 can be implemented using pipies either directly or with extra abstraction - e.g . RingBuffer or the google lib from the other comment . Indeed with standard java there is no other way to solve the problem . Each solution is an implementataion of one of these . There is one concept called continuation see wikipedia http : en.wikipedia.org wiki Continuation for details . In this case basically this means : .. . .. . there is a special output stream that expects a certain amount of data .. . if the ammount is reached the stream gives control to it s counterpart which is a special input stream .. . the input stream makes the amount of data available until it is read after that it passes back the control to the output stream .. . .. . While some languages have this concept built-in for java you need some magic . For example commons-javaflow from apache implements such for java . The disadvantage is that this requires some special bytecode modifications at build time . So it would make sense to put all the stuff in an extra library whith custom build scripts .", "Question : Can anyone explain me about InputStream and OutputStream I am confused about use cases for InputStream and OutputStream .. . .. . An explanation with some code snippet will be great . I just need to figure out their difference and usage . .. . Answer : InputStream is used for reading OutputStream for writing . The are connected as decorators to one another such that you can read-write all different types of data from all different types of sources . For example you can write primitive Data to a file : .. . .. . To read the written contents : .. . .. . You can use other types of streams to enhance the reading writing . For example you can introduce a buffer for efficiency : .. . .. . You can write other data such a objects : .. . .. . You can read from other different input sources : .. . .. . For most input streams there is an output stream also . You can define your own streams to reding writing special things and there are complex streams for reading complex things for example there are Streams for reding writing ZIP format .", "Question : In Java I need to put content from an OutputStream I fill data to that stream myself into a ByteBuffer . How to do it in a simple way Comment : Generally you can t read directly from an output stream . If you fill the data yourself why can t you fill it into the ByteBuffer as well Comment : It is possible to read from it indirectly and of cause directly as well if you create class that inherits form OutputStream and make it possible to read from it directly . I did not fill the data myself some framework did and the framework s code I don t want to touch of cause . See my other comment and answers as well . .. . Answer : You can create a ByteArrayOutputStream and write to it and extract the contents as a byte using toByteArray . Then ByteBuffer.wrap byte will create a ByteBuffer with the contents of the output byte array . Comment : That is exactly what I ve done just before I ve read your comment . So I can approve that this works : Comment : Unfortunately ByteArrayOutputStream toByteArray makes a copy of the underlying byte array so while this prescription is simple it s not as efficient as we d like . However since ByteBuffer is fixed in capacity the desire for writing an arbitrary amount of data through an OutputStream into a ByteBuffer is irreconcilable . Comment : @seh It does not have to be this way - see my answer .", "Question : How can I create class that takes an implentation of OutputStream and writes the the content to it For example the following print method is wrong and will not compile . What are the options or better techniques Comment : You should 1 look at the OutputStream API and use methods available to it and 2 if you have an error post the error here so we don t have to guess what is wrong . Comment : For instance the API will show you that there is no OutputStream method called write .. . that takes a String parameter and so you can t just make one up and expect it to work . Instead you must use the methods that are available . .. . Answer : A generic OutputStream doesn t have the ability to write a String directly to it . Instead you need to get the byte of the String and then write them out to the stream . Refer to the OutputStream http : docs.oracle.com javase 1.4.2 docs api java-io OutputStream.html java documentation for more information on the supported write data types . My suggestion for making this better is to make sure the OutputStream you provide in the constructor is a BufferedOutputStream as this will improve the performance of your code . It works by buffering some of the data in memory and writing it out to disk in big chunks instead of many smaller writes . Here is the java documentation for BufferedOutputStream http : docs.oracle.com javase 1.4.2 docs api java-io BufferedOutputStream.html", "Question : I am writing an OutputStream just noticed this in the OutputStream interface .. . .. . This call write one byte to the stream but why it takes integer as an argument .. . Answer : So you can signal EOF : .. . .. . Notice that read returns an int value . If the input is a stream of bytes why doesn t read return a byte value Using a int as a return-type allows read to use -1 to indicate that it has reached the end of the stream . http : java.sun.com docs books tutorial essential io bytestreams.html Comment : mhm good point Comment : So if you write -1 what happens Does it close the stream : - Comment : Nope . You end up writing strange Unicode characters to output stream . But if there were a recieving stream for your write -1 I do believe it would signal end of stream to that stream . There are 3 possibilities for streaming : The first 2 transfer a specified number of bytes : write byte b int off int len and write byte b . The third option lets you transfer an undetermined number of bytes by using int . That s why int is used . Comment : In other words write int is there for symmetry with read . That s not so bad when you think about it . Good answer . Comment : I don t think so . For one OutputStream has a close method and any OutputStream you use together with an InputStream will likely be written by you .", "Question : I can t find anything in the Swift book about io .

Comment : I agree Swift is lacking in this area at the moment but it is designed to work with Cocoa frameworks . is there something specific you are trying to do Comment : @tony Very curious - why would you not use NSStream I don t think that just because Swift is around doesn t mean Cocoa is going away . I d say it s a very legitimate way to work with streams in Swift . Comment : @macandyp No I will use NSStream and of course it is legitimate way to do it . It just doesn t seems very idiomatic .

So I don t think this is the solution . .. . Answer : I think the best way to connect InputStream to an OutputStream is through piped streams - available in java.io package as follow : .. . .. . In my opinion there are two main advantages for this code : .. . .. . 1 - There is no additional consumption of memory except for the buffer . 2 - You don t need to handle data queuing manually Comment : This methodology results in a deadlock at least in my test . JavaDoc : A piped output stream can be connected to a piped input stream to create a communications pipe . The piped output stream is the sending end of the pipe . Typically data is written to a PipedOutputStream object by one thread and data is read from the connected PipedInputStream by some other thread .

How to do it in a simple way Comment : Generally you can t read directly from an output stream . If you fill the data yourself why can t you fill it into the ByteBuffer as well Comment : It is possible to read from it indirectly and of cause directly as well if you create class that inherits form OutputStream and make it possible to read from it directly . I did not fill the data myself some framework did and the framework s code I don t want to touch of cause . See my other comment and answers as well . .. . Answer : Though the above-mention answers solve your problem none of them are efficient as you expect from NIO . ByteArrayOutputStream or MyByteArrayOutputStream first write the data into a Java heap-memory and then copy it to ByteBuffer which greatly affects the performance . An efficient implementation would be writing ByteBufferOutputStream class yourself . Actually It s quite easy to do . You have to just provide a write method .

This call write one byte to the stream but why it takes integer as an argument .. . Answer : Maybe it s because bytes are signed by default and files store bytes as unsigned values .

Answer : If you compare your code adaptation with the version presented in MSDN page http : msdn.microsoft.com en-us library system.io.compression.ziparchive.aspx you ll see that the ZipArchiveMode.Create is never used what is used is ZipArchiveMode.Update . Despite that the main problem is the OutputStream that doesn t support Read and Seek which is need by the ZipArchive in Update Mode : .. . .. . When you set the mode to Update the underlying file or stream must support reading writing and seeking .

When you set the mode to Create the underlying file or stream must support writing but does not have to support seeking . Each entry in the archive can be opened only once for writing . If you create a single entry the data is written to the underlying stream or file as soon as it is available . If you create multiple entries such as by calling the CreateFromDirectory method the data is written to the underlying stream or file after all the entries are created . .. . Source : MSDN http : msdn.microsoft.com en-us library system.io.compression.ziparchivemode.aspx .. . .. . I believe you can t create a zip file directly in the OutputStream since it s a network stream and seek is not supported : .. . .. . Streams can support seeking . Seeking refers to querying and modifying the current position within a stream . Seek capability depends on the kind of backing store a stream has . For example network streams have no unified concept of a current position and therefore typically do not support seeking . An alternative could be writing to a memory stream then use the OutputStream.Write method to send the zip file . EDIT : With feedback from comments and further reading you could be creating large Zip files so the memory stream could cause you problems . In this case i suggest you create the zip file on the web server then output the file using Response.WriteFile . Comment : So in other words it s impossible to write it directly to the outputStream Like I said before a memoryStream is not an option as the file sizes vary and can become huge . Comment : I m trying with response.filter to see if i can find a workaround but according to MSDN you can t : Streams can support seeking . Seeking refers to querying and modifying the current position within a stream . Seek capability depends on the kind of backing store a stream has . For example network streams have no unified concept of a current position and therefore typically do not support seeking .

Calling-code looks like this : .. . .. . Note - In practice the same client executor service and config will likely be reused throughout the life of the application so the outer prep and close code in the above example will likely live in bootstrap init and finalization code rather than directly inline with the OutputStream instantiation .", "Question : On IBM Domino Server version 8.5.3FP1 on Win32 platform there are two web-agents to generate PDF and RTF files by request .

Files are generated and saved correctly in temporary folder . But writing these files to OutputStream to let a user save it to the local disk it does not work properly .

An explanation with some code snippet will be great . I just need to figure out their difference and usage . .. . Answer : you read from an InputStream and write to an OutputStream . for example say you want to copy a file . You would create a FileInputStream to read from the source file and a FileOutputStream to write to the new file . If your data is a character stream you could use a FileReader instead of an InputStream and a FileWriter instead of an OutputStream if you prefer . Comment : close always flush es so no .", "Question : I am trying to write a function that takes File object offset and byte array parameters and writes that byte array to a File object in Java . So the function would look like .. . .. . But the problem is that the offset parameter is long type so I can t use write function of OutputStream which takes integer as an offset . Unlike InputStream which has skip long it seems OutputStream has no way to skip the first bytes of the file . Is there a good way to solve this problem Thank you . Comment : The largest number you can put in an int is 2 147 483 647 . Are the arrays you want to write larger than +- 2GB Comment : Just for clarification : the offset only applies to the position in the array not the output stream right With an OutputStream you can not skip positions . Comment : @TheNail offset refers to the offset from the beginning of the file not the beginning of the array . And unless you are using FAT as a file system you can indeed have files larger than 2Gb . Comment : Ah FYI : the int offset parameter off in OutputStream.write is about the array not the stream file but I see there are some relevant answers already . .. . Answer : That s to do with the semantics of the streams . With an input stream you are just saying that you are discarding the first n bytes of data . However with an OutputStream something must be written to stream . You can t just ask that the stream pretend n bytes of data were written but not actually write them . The reason for this is because not all streams will be seekable . Data coming over a network is not seekable -- you get the data once and only once . However this is not so with files because they are stored on a hard drive and it is easy to seek to any position on the hard drive .

Comment : @EugeneKuleshov How do I get an output Stream using org.apache.http.impl.client.DefaultHttpClient .. . Answer : You can t get an OutputStream from BasicHttpClient directly .

For instance if your output is small enough to fit in memory you might do the following : .. . .. . If the data is large enough that you need to stream it it becomes more difficult because there s no HttpEntity implementation that accepts an OutputStream . You d need to write to a temp file and use FileEntity or possibly set up a pipe and use InputStreamEntity .. . .. .

On the other hand in the interests of getting some working code I d like to prototype out sections of a Nim app I m working on in ruby . Since mruby allows embedding a ruby subset in a C app and since nim allows compiling arbitrary C code into functions it feels like this should be relatively straightforward . Has anybody done this I m particularly looking for ways of using Nim s funky macro features to break out into inline ruby code . I m going to try myself but I figure someone is bound to have tried it and or come up with more elegant solutions than I can in my current state of learning : .. . Answer : https : github.com micklat NimBorg .. . .. . This is a project with a somewhat similar goal . It targets python and lua at the moment but using the same techniques to interface with Ruby shouldn t be too hard . There are several features in Nim that help in interfacing with a foreign language in a fluent way : .. . .. . 1 Calling Ruby from Nim using Nim s dot operators http : nim-lang.org docs manual.html special-operators-dot-operators .. . .. . These are a bit like method-missing in Ruby . You can define a type like RubyValue in Nim which will have dot operators that will translate any expression like foo.bar or foo.bar baz to the appropriate Ruby method call . The arguments can be passed to a generic function like toRubyValue that can be overloaded for various Nim and C types to automatically convert them to the right Ruby type . 2 Calling Nim from Ruby .. . .. . In most scripting languages there is a way to register a foreign type often described in a particular data structure that has to be populated once per exported type . You can use a bit of generic-programming and Nim s .global . vars to automatically create and cache the required data structure for each type that was passed to Ruby through the dot operators . There will be a generic proc like getRubyTypeDesc T : typedesc that may rely on typeinfo typetraits or some overloaded procs supplied by user defining what has to be exported for the type . Now if you really want to rely on mruby because you have experience with it for example you can look into using the .emit . pragma http : nim-lang.org docs manual.html implementation-specific-pragmas-emit-pragma to directly output pieces of mruby code . You can then ask the Nim compiler to generate only source code http : nim-lang.org docs nimc.html cross-compilation which you will compile in a second step or you can just change the compiler executable which Nim will call when compiling the project this is explained in the same section linked above . Comment : Wow some excellent pointers there thank you", "Question : I m trying to understand what kind of approach is used by Nim to distinguish between commands . There s the separatist approach where a semicolon just separates commands used in Pascal for example the terminist approach where a semicolon completely terminates the command used in C C++ Java etc . and the liberal approach where the programmer can decide whether or not to use a semicolon . My thoughts are that Nim belongs-to the liberal approach but that would mean that semicolons could be added at the end of commands and Nim doesn t support that . Any other thoughts .. . Answer : Nim like Python is a whitespace-aware language . It uses newlines as statement separators and indentation to produce block structures . Not all languages have visible statement separators although some allow a visible statement separator in some circumstances . For example in Python simple statements can be separated by semicolons but not compound statements .

My guess is that on Heroku you are using Nim 0.11.2 which is the latest release and on your local computer you are using the devel version which does not have this bug . In any case the solution should be to update the version of Nim that heroku uses .

The problem is I don t know what I did wrong . .. . Answer : The document really should say objfile . Executables and shared-libraries are handled exactly the same except that shared-libraries can be dlopen ed so in that case the script can be called later . In either case simply create a file named objfile-gdb.py that code will be executed whenever the objfile is loaded . That script can either or you may prepend one of the debug roots to the full path typically usr share gdb auto-load and usr lib debug . Note that there are some infelicities regarding if an objfile is loaded more than once typically if you restart the application using run - I have not tested if this also occurs with a dlopen - dlclose - dlopen sequence or if you use split debuginfo since that counts as a separate objfile but uses the same script . I have some vague thoughts regarding a virtual python package with a custom path that changes on every execution that could solve this .. .

Could it work without variables initialized on compile-time Comment : One should mention that interpolatedFragments will break on something like a b since it only counts braces . strfmt currently also suffers from this but there should be a way to solve it by making interpolatedFragments a compileTime iterator allowing to use parseExpr to properly parse an expression . Comment : @Arrrrrrr why wouldn t it The macro doesn t do anything to variables it only transforms the literals to break them up into concatenations . Added some runtime lines to example . Comment : @bluenote10 interpolatedFragments is very simple and wasn t intended for nested braces .

Comment : @GrzegorzAdamHankiewicz : What I m trying to say is that since the macro is expanded at compile-time the full power of the compiler is available anyways and it would make sense to use its expression parser if possible instead of parsing it manually .

Are there no other messages Why do you think this is a crash Does a window show up then immediately disappear Or does nothing happen Can you post a complete minimal example that demonstrates the problem Comment : Two things : Plugin.py still has from Task import Visualization where you should have from Visualization import Visualization . And in your PythonEditorPane which it is time to rename your create method does not assign the GLWidget that you instantiated to self.control . Fix those two things and your example works for me . .. . Answer : The control trait of a TaskPane is just the Qt widget object that you are using . In the example that you link we happen to be getting it from another PyFace widget that wraps a Qt widget in a similar fashion so we just grab the control attribute from it . You should just directly use a QGLWidget http : qt-project.org doc qt-4.7 qglwidget.html as the control of your pane . Please consult the Qt documentation for how to use it .

The DRL in guvnor will refer to java objects uploaded in guvnor . From standalone application if i point to guvnor DRL and run application how will the pojo attributes will get updated in standalone program after the rules get executed basically 2 diff JVM right Comment : Sounds like the basics are working . object asserted means that a fact has been inserted into the session . activation created means that one of your rules fired . All the Java objects are local to your application one JVM They don t exist in Guvnor - Guvnor just needs them to be able to compile rules so you can just modify their properties directly .

Also it would not make sense to do this as the only reason to have a decision table in Guvnor is to enable editing of it in Guvnor .

I understand the drawbacks of this but the client doesn t want to use Guvnor s interface for editing the rules . .. . Answer : If you want to maintain rules in a database-table then you should be looking at rule templates : .. . .. . http : docs.jboss.org drools release 6.0.1.Final drools-docs html single index.html d0e4969 .. . .. . Rule templates provide a relatively simple mechanism for merging DRL with data . FWIW - The documentation for this in the manual is poor so here is a hint on the kind of thing you need to do : .. . .. . To generate rules from a combination of database data and a template you will need to import org.drools.template.jdbc.ResultSetGenerator . This class can be used to generate DRL code from a database query result set and a template . Then you create a package through the API and add that generated DRL to it . Comment : Yes we have tried to use rule templates and upload them manually in Drools . Is there a way to automatically feed the data in these spreadsheets in Guvnor I would prefer feeding directly from the DB which the client would just update through an interface but I m all open for any options . Comment : The point is that they should not be in Guvnor . Guvnor is not the runtime environment . It is a place for editing rules . Therefore if you intend to maintain rules in a database-table then those rules should not be in Guvnor . Comment : I understand your point . The only thing is that there is an immense amount of combinations for the available data which would prove difficult to manage in Guvnor s interface . I obviously am not an expert on this which is probably why I m having a hard time understanding what can and what cannot go into Guvnor . Comment : The rule templates that you can create in Guvnor are completely different things from the Expert rule templates . Or at least how you use them is completely different .

Hope this helps blog.sudhakarduraiswamy.in java http : www.blog.sudhakarduraiswamy.in java what-is-rules-engine-and-brief-analysis-of-whats-available-in-the-market .. . Answer : I m in the process of doing something akin to what you want to do . Since these business-rules would be very often by the business I would want the business to make necessary changes to the rules via GUI . .. . .. . WARNING WARNING WARNING It s a common misconception that as long as there s a GUI non-programmers can use it . That s.. . not the conclusion I ve come to . It helps but the hard part of programming isn t writing code it s coming up with good solutions to the right problems . I m certain some of the more intelligent and technically inclined business folks can do stuff with Guvnor but don t expect it to be some kind of yellow brick road to the Land of Magical Bliss . You still have to provide the business people with a sane data model and API which lets them do what they need but which prevents them from doing by accident what they don t want to do . 1 . Does Drools support a lightweight GUI for editing the rules .. . .. . 2 . Is Drools Guvnor a lightweight GUI or is there are a way to step it down .. . .. . Well lightweight is subject for discussion but Guvnor works fairly well and doesn t require more than a browser so I think it s OK . .. . .. . 3 . How easy to integrate an application to Guvnor to read the rules .. . .. . Well once you ve got Guvnor up and running wiring up your application to use a KnowledgeAgent to connect to Guvnor and listen for new rule updates isn t particularly hard . Unfortunately Drools in general and Guvnor in particular has a bunch of quirks which you may have to work around for instance you have to explode the Guvnor WAR file and edit files in WEB-INF beans.xml to set up a non-default configuration.. . . But once you ve got that straightened out I think it works pretty well . As for documentation the Javadocs can be a bit sparse at times but the web site http : www.jboss.org drools documentation has some pretty good stuff and including several books . All in all Drools and Guvnor are powerful tools but it s not trivial to get them working . If you really need what they have to offer they re worth it but it might also be worth considering if a simpler scripting solution will suffice . .. . .. . Now if you find yourself actually needing Drools here s my top piece of advice - keep separate data models for your database and your rules . It does mean there s a lot of boring conversion code to write but it s well worth it . The app I m working on uses JPA for database matters and it wouldn t have been very pleasant to use that data model in our rules . Several reasons : .. . .. . What s fits your data-layer doesn t necessarily fit Drools and vice versa . .. . .. . We have a tree structure which in JPA naturally is a @OneToMany relation with the children in a list in the parent node . Working with lists in Drools was rather painful so we flattened it to a structure where we insert one ParentNode object and a bunch of ChildNode objects which was far easier to work with . Dare to refactor . .. . .. . The rule s data model needs to live inside of Guvnor too - and that means you could break all rules if you rename an entity class or something like that . A separate data model for rules means you can refactor your database stuff without worries . Show them what they need to see . .. . .. . Databases can grow fairly complex but the rules normally don t need to care about many of these complexities . Exposing these complexities to the people editing rules can cause a lot of unnecessary confusion . For example we ve found that for our scenarios there s absolutely no need to expose rule writers to many-to-many relationships which proved very complicated to handle in Drools - so we make them look like one-to-many instead and everything becomes more natural .

We ve designed most our rules to work like this pseudo-code : .. . .. . .. . and so for each rule package it s clearly defined which response commands you can insert and what they do . After we ve run the rules in our app we pick out the objects inserted into the session by the rules and act upon them the visitor pattern https : secure.wikimedia.org wikipedia en wiki Visitor pattern Java example has proven very useful to avoid long if instanceof else if instanceof else chains .

Comment : can t really say if you dont show your outputs for both cases Comment : Thanks anyway I guess I have to read more to understand guvnor and drools .. . Answer : DRL and PKG are file types for two different things . Compared to the programming language C they correspond to .c and .o . More accurately a DRL file is the Drools Rule Language text which can be written with a text-editor or is generated from your input in the Drools IDE Guvnor or its successor in 6.x . A DRL file must be compiled by the Drools DRL compiler used in the Builder the result is a binary Rule Package file the .PKG . For creating a Rule Base and from it in turn a session you may use the rule package . Comment : Thanks for your explanation . Why I don t understand is how I get 2 different results from the same rules . I haven t written the rules myself I have used guvnor . I don t understand why drools gives me 2 different sets of rules if I have only written one set of rules with the guvnor tool", "Question : I have imported the DRL file and required pojo as individual jar file in guvnor .

But I still did not succeed in what I m doing . I have a standalone drools app which has DRL file that validates my incoming data and flags the erroneous data . Say I have an user object to validate age check eligibility for voting In my DRL the user object will be imported and rule defined for age check . In case of erroneous message I will set something in user object itself . How do I make this whole thing available in Guvnor for runtime rule updation Comment : I suspect you may need to create a new question around that . : But essentially Guvnor is just a store for the rules . You application needs to run separately and load in the rules from a remote Guvnor instance . Search the Guvnor docs for knowledge agent . This is the piece provided by Drools to automatically reload rules from Guvnor or elsewhere when they are changed . .. . Answer : Without seeing the DRL I ll take a guess . I suspect that you re using the mvel dialect but your DRL is doing things which assume the Java dialect . Try changing that . You can see an example of this here : .. . .. .

Comment : One more thing when I say I want to store rules in database I mean individual value combination of attributes not rule files.Like mentioned here : stackoverflow.com questions 4392664 http : stackoverflow.com questions 4392664 drools-storing-rules-in-database Comment : Generally the database interactions won t happen in the rules . You need to insert facts into working memory . These facts can be Java classes which have been marshalled from values held in a database if you like .

We ve gone through Service Worker and all . We have developed a prototype using this codelab https : developers.google.com web fundamentals getting-started push-notifications hl en tutorial . It is working so far but the only issue is the notifications are displayed only when Chrome is opened . When Chrome is closed the notifications don t reach the users . I want to know is there any way we can overcome this and display the notifications even when the browser is closed similar to Safari Push Notification . Thanks in advance .. . Answer : If you have a background https : developer.chrome.com extensions manifest permissions permission your background page will be able to show notifications even when Chrome window is closed . It was stated in this documentation https : developer.chrome.com extensions declare permissions . When any installed hosted app packaged app or extension has background permission Chrome runs invisibly as soon as the user logs into their computer before the user launches Chrome . The background permission also makes Chrome continue running even after its last window is closed until the user explicitly quits Chrome . You need to use the background permission with a background page https : developer.chrome.com extensions background pages event page https : developer.chrome.com extensions event pages or a background window https : developer.chrome.com apps app window for hosted apps . For web use Push API for Chrome and other browsers . The advantage of using push messages is that even if your page is closed your service-worker will be woken up and be able to show a notification . Web Sockets and EventSource have their connection closed when the page or browser is closed so it s not recommended .

Currently Firefox adhere to the standard while Chrome uses an hybrid solution Push API + GCM .

More info at MDN at developer.mozilla.org en-US docs Web API Push API https : developer.mozilla.org en-US docs Web API Push API Using the Push API .. . Answer : Yes you can send off-site push notifications without an app using the W3C Push API . However the only mobile-browser that supports them is Chrome on Android while most desktop browsers already support them . If you want to build everything from scratch I suggest reading this tutorial https : developers.google.com web updates 2015 03 push-notifications-on-the-open-web .

I also discovered that Google Apple gives push-notification service for free via GCM and APNS respectively . I am trying to understand if we can implement push-notification to browsers using Desktop Notification which I believe is what Web Notification API does .

Now what am still not able to understand is : .. . .. . 1 . Can we use GCM APNS to send push-notification to all Web Browsers including Firefox Safari 2 . If not via GCM can we have our own back-end to do the same I believe all these answered in one answer can help a lot of people who are having similar confusions . Comment : sure you can run your own backend but it s complicated . .. . Answer : I assume you are talking about real push notifications that can be delivered even when the user is not surfing your website otherwise check out WebSockets or legacy methods like long-polling . Can we use GCM APNS to send push-notification to all Web Browsers including Firefox Safari GCM is only for Chrome and APNs is only for Safari . Each browser manufacturer offers its own service . If not via GCM can we have our own back-end to do the same The Push API requires two backends One is offered by the browser manufacturer and is responsible for delivering the notification to the device . The other one should be yours or you can use a third party service like Pushpad http : pushpad.xyz and is responsible for triggering the notification and contacting the browser manufacturer s service i.e .

I am developing a chrome and a firefox extension add-on . I am using the Web Extension APIs for Firefox extension . Now Web Extension APIs don t support chrome.gcm . APIs yet . Essentially a firefox extension cannot talk to GCM . Is there something else like GCM to which a firefox extension can talk to Something provided by the Firefox just like GCM provided by Google for its browser Chrome If not can someone please explain how to achieve this in a Firefox Extension Update : Even for web apps firefox doesn t use something similar to GCM . They use service workers . Can Firefox Browser Extensions interact with service workers .. . Answer : Firefox extensions currently can t use service workers directly according to an implementor who worked on service-workers support in Firefox http : logs.glob.uno c freenode 23whatwg s 1 20Feb 202016 e 1 20Feb 202016 c983254 . Is there something else like GCM to which a firefox extension can talk to Something provided by the Firefox just like GCM provided by Google for its browser Chrome Yes there s a Firefox equivalent of GCM . All Web apps a Firefox user accesses that receive push notifications get them from a server given by the dom.push.serverURL user preference . If you check dom.push.serverURL in about : config you ll see wss : push.services.mozilla.com which is the Mozilla Push Service https : mozilla-push-service.readthedocs.org en latest essentially Mozilla s equivalent of GCM . The backend of that runs AutoPush a Python-based open-source Push Server software project https : autopush.readthedocs.org en latest and the client-side of it is as noted in the question exposed to Web apps through service workers . So while there may be an alternative way Firefox extensions can connect with Mozilla Push Service the only publicly-documented way is through the standard Web Push API https : developer.mozilla.org en-US docs Web API Push API Using the Push API that relies on service workers which are not available yet for use in Firefox extensions . Comment : So do you know of any alternatives using which Firefox extensions can connect with Mozilla Push Service Comment : You might be able to use one of the Firefox modules that implement Web Push mxr.mozilla.org mozilla-central source dom push http : mxr.mozilla.org mozilla-central source dom push . Comment : @Marco How I think this also is for web apps only . Comment : @ankitG those modules are internal they can t be used by web content but can be used by addons . I m not sure about the how you have to investigate by looking at their source code . Comment : There s also something else that you could do . Create a web page that uses service workers and the standard Push API and somehow communicate data between the addon and the web page .", "Question : I am currently sending web-notifications on Firefox desktop browsers . Unfortunately deleted tokens are still pushable through Mozilla Push Server . To delete the token i.e . the subscription endpoint generated by the ServiceWorker I just clear the cache history . Then I send a notification to the deleted endpoint : Mozilla returns a 201 Created telling us the notification has been created for the user and ready to be send . But if I repeat the same steps with a Chrome browser Google Cloud Messaging tells us that the token is not registed cf GCM documentation https : developers.google.com cloud-messaging http-server-ref error-codes Unregistered Device . However I can clearly see in Mozilla documentation http : autopush.readthedocs.io en latest http.html errors that there are error codes for this situation : cf errno 103 - Expired URL endpoint or errno106 - Invalid subscription . Also I must say that if I block the native notification permission previously granted Mozilla returns in consequence a errno106 - Invalid Subscription error . The problem is when the token has been deleted . Comment : I don t understand what you mean when you say the token has been deleted . A token is deleted meaning that is no longer valid when the user blocks the native notification permission . Comment : @collimarco To put it plainly : a user has an endpoint and receives web-push . But if he clears his browser-cache he won t receive web-notifications anymore . So this endpoint becomes useless . I want Mozilla to tell me that I should never send to this endpoint anymore . Comment : I agree with you . There are some cases when you don t know if the notification will be delivered . However this is a problem regarding the Push API specs or how Mozilla handles that : I don t think that here on StackOverflow someone can provide a solution . .. . Answer : Mozilla has been working on this unwanted behavior : BugZilla 1277615 https : bugzilla.mozilla.org show bug.cgi id 1277615 .. . .. .

Answer : I m trying to understand the capabilities of the Web Push Notifications https : developers.google.com web updates 2015 03 push-notifications-on-the-open-web hl en via Google Cloud Messaging and Chrome . I ve implemented and tested it in Chrome full browser and the UX is pretty good specifically : .. . .. . If the Chrome application is open then a visible notification arrives good .

It is something similar to how facebook.com displays notifications in chrome and firefox . I m also working on an Android app that also supports push notifications through GCM . So I need help on how to add push-notification support to my website . Thanks in advance .. . Answer : You can use Service Workers in order to display notifications from a website as stated in Implementing GCM Client on Chrome https : developers.google.com cloud-messaging chrome client . You can refer to push messaging codelab https : developers.google.com web fundamentals getting-started push-notifications hl en on how to implement it .

On desktop Chrome has to be running but lets be honest people always have a browser window sat around somewhere :", "Question : All of my questions are in context of Chrome Web Push Notifications as released in Chrome Version 42 . 1 GCM API returns Success for even those Registration IDs which are no longer valid . When a person right clicks on the notification and clicks on Disable notifications from xyz.com the person can no longer receive notifications . However when i send the same RegistrationID to GCM API it still returns success for that particular registration . When i resubscribe again i get a new RegistrationID . Therefore I suspect that the previous one gets disabled . Is this intended behaviour Is there any way for us to know if people have unsubscribed by right clicking on the notification and mark them as inactive in our database in case the user never comes back again . 2 GCM Documentation for Error NotRegistered says The client app isn t configured to receive push messages or the app was uninstalled from the device . Can you please explain what does The client app isn t configured to receive push messages mean Comment : These are two questions . but the second one is easy notregistered means you can no longer send to that ID . Please post as two questions you might get answers . .. . Answer : Disable notifications from xyz.com .. . .. . All this does is revoke the notification permission in Chrome and unregister from push . The GCM server might take a while to realize that such registration is no longer valid since the unregistration happens locally and it can take a while to be synced back to the servers . Is there any way for us to know if people have unsubscribed by right clicking on the notification and mark them as inactive in our database in case the user never comes back again . Sending messages to that registration id will eventually start returning a permanent error one of InvalidRegistration NotRegistered InvalidPackageName MismatchSenderId .. . .. .

I want to know is there any way we can overcome this and display the notifications even when the browser is closed similar to Safari Push Notification . Thanks in advance .. . Answer : In Chrome . Only those users that happen to have an extension installed that requires background mode like hangouts will be able to receive push notifications when chrome is not running .

Answer : If you build a native app or you use a native wrapper like Phonegap around an html javascript app you have to distribute it through the App store . If you go for a website you can send real push notifications using the Push API there are service like Pushpad https : pushpad.xyz that make it easier . Currently the only mobile-browser that supports the Push API is Chrome in Android however more will probably come soon .", "Question : I ve been reading through the docs for Chrome s implementation of the Web Push API here http : updates.html5rocks.com 2015 03 push-notificatons-on-the-open-web and I noticed the API says you promise to show a notification whenever you receive a push and under limitations it s stated you have to show a notification when you receive a push message . After implementing the example on my localhost I used cURL to send a push-notification successfully . I was curious so I commented out the lines that actually call the showNotification function and put in a console.log instead and found that I could in fact send receive and totally ignore a push-notification . I even tried using an if-statement to control whether or not to show them based on global boolean that I controlled from my main page and that worked . So I was wondering if anyone knew what they meant by saying you need to show a notification and that silent push notifications weren t available This wasn t just for the heck of it I legitimately may need to control whether or not to show these notifications in my web app so it would be great if this were actually possible . Code below in case you re curious . EDIT : On Chrome 47 if it s relevant . UPDATE : After further experimenting I found the obvious issue that I can t update the original global variable once the user navigates away and then re-navigates to the same page . However I was able to circumvent this using a variable on the serviceworker itself and sending a message to the service-worker using the API described here https : googlechrome.github.io samples service-worker post-message to toggle the showNotifications boolean . .. . Answer : You do have to show a notification and if you don t show a notification you get a forced notification from the browser saying This site has been updated in the background . But the requirements that show the scary message have been relaxed slightly : .. . .. . As of Jan . 16 it seems like up to the last 10 notifications are checked for whether each showed a notification or not . If one notification in the last ten notifications did not show a notification that s considered an accident and the browser won t show the scary This site has been updated in the background . You have to miss two notifications in the last ten for the scary message to appear . Note : If the URL in the address-bar of the active browser tab matches the origin of your page and the browser is not minimized you are not required to show a notification . This is probably why your tests succeeded if you were on the page itself while running your tests .

What do I do .. . Answer : chrome.gcm https : developer.chrome.com apps gcm was a proprietary push API built for Chrome Apps and Extensions which the user has to install . There is a new API called Push API spec http : www.w3.org TR push-api which is a web standard based on service workers http : www.html5rocks.com en tutorials service-worker introduction and available to normal websites . This walkthrough explains how to send notifications from your website and should get you up and running : https : developers.google.com web fundamentals getting-started push-notifications", "Question : I am implementing chrome push-notification for my website users .

I am following these articles tutorials .. . .. . 1 . https : developers.google.com web updates 2015 03 push-notifications-on-the-open-web hl en .. . 2 . http : www.html5rocks.com en tutorials service-worker introduction .. . .. . This works very well when I want to send notification NOW i.e . without scheduling for future . My Problem : .. . .. . I want to schedule this notification for later in the day may be recurring which I can do via cron . But GCM does not send you payload as stated here https : developers.google.com web updates 2015 03 push-notifications-on-the-open-web hl en and I quote . A downside to the current implementation of the Push API in Chrome is that you can t send any data with a push message . Nope nothing . The reason for this is that in a future implementation payload data will have to be encrypted on your server before it s sent to a push messaging endpoint . This way the endpoint whatever push provider it is will not be able to easily view the content of the push message . This also protects against other vulnerabilities like poor validation of HTTPS certificates and man-in-the-middle attacks between your server and the push provider . However this encryption isn t supported yet so in the meantime you ll need to perform a fetch to get information needed to populate a notification . Because of this I am not able to figure out for which scheduled notification I have received push event in browser . As there might be multiple notification sent to GCM . I am fetching last record in notification tables i.e . I am always showing last record data . As I don t know for which notification I am receiving push event in chrome browser . My Question : .. . .. . Is there a workaround to schedule notifications and show correct ones to the client browser Is it even possible in native chrome push-api .. . Answer : When you fetch the notification data you can mark this entry as read or delete it . Doing this way you can achieve that when there are two messages for user to show the first fetch request takes the first unread message and marks it as read and the second one can t take the previous message as it is already marked . Another solution would be to take all unread messages in one fetch request and show all of them to user . Doing this you might have empty pushes that do nothing .", "Question : This is my first post on the forum so please educate me if I got the tag forum or content wrong .

Answer : Question : do you want the push to occur only when the user has an open browser with the web application open I m asking the question since you insist on the fact that you must do a web app and not native apps . If it s the case you may use some javascript push libraries . But be aware the even if it s js you ll have an additional socket connection open in addition to the native one for the push . So this will be battery consuming which could be a reason why people would stop using your app . If you want real-time notification you d better address the native push mechanism on each platform maybe with phonegap or titanium Comment : Yes the challenge is that I want to find a way to do push notifications when the app is not active . That s why I figure I have to link-to some native notification outside the app . Email is possible but not very real-time . SMS is more real-time but costly . IM could be a way .

In lieu of a service-worker event standard why not just keep the expected subscription endpoint around in client-side state and anytime you query the PushManager for the subscription check if it is out-of-sync different than expected .. . Answer : The pushsubscriptionchange event is documented as part of the Push API specification https : w3c.github.io push-api the-pushsubscriptionchange-event .

The link-to the Sun C++ Frontend Tales is broken for instance . Looks like the Boost developers do not actively test with Solaris Studio any more . I wanted to help see boost.org development running regression tests.html http : www.boost.org development running regression tests.html but that does not work either the process jam log object cannot be compiled . This happens well before any of the actual tests can be run . Ain t look good : - .. . Answer : The first thing to know about building Boost with Solaris Studio is that the Jam file hasn t been updated for over 5 years and uses STLport as its C++ standard-library . This may not be what you want . Solaris Studio 12.4 can be run in C++11 mode where it uses the GNU libstdc++ to provide its standard-library . Even if you re running in the default C++03 mode you d probably want to use the Apache C++ standard-library . If you re not using STLport for the rest of your C++ code then ask another question about changing the Boost Jam files for Solaris Studio to use a different standard-library . Moving on to the exact error messages you re seeing I think all the ones in the archive library have the same cause and it s easy to fix . Edit boost archive detail register archive.hpp and change line 31 from : .. . .. . to : .. . .. . A long time ago somebody added a workaround for a bug in an old version of Solaris Studio but now Solaris Studio 12.4 finds the workaround code to be invalid but can cope with the code all the other compilers see . For the platform not supported message from the context library you re out-of-luck if you re on Solaris but maybe it doesn t matter if you re not using this particular Boost library . The Linker scopes may not change after symbol definition errors are caused by an attempt to use Solaris symbol visibility directives .

Comment : No need to write anything in C extern C to get C linkage is enough . Also most systems by now have a C++ ABI . Just make sure to avoid using anything not covered by it Which means mostly some library-features . Comment : An arguably better solution is to keep the library as source code and compile for whatever platform on demand . Comment : @Deduplicator I know that Solaris Studio has issues with some STL components . Would this work for methods like code myMethod std : : vector myClass data code Comment : @n.m . Solaris Studio does not compile my library since it does not compile third pary libs such as Apache Qpid Comment : Well that sucks . File bug reports with both vendors . .. . Answer : Your plan is correct . As long as your library exposes a C API compatible with platform ABI sizes and alignments of C types calling conventions and does not throw C++ exceptions you are not going to have troubles linking your library using other compilers or languages . You could also add a C++ header-only wrapper for your C API to make it easily reusable from C++ and exception safe . Comment : You were right to point out exceptions as a possible issue .

I am unable to compile libpqxx-4.0.1 on Solaris 10 using Solaris Studio 12.3 . Background .. . .. . The first thing I did when I needed libpqxx was to search for it in OpenCSW using opt csw bin pkgutil -a libpqxx . However the package in OpenCSW is listed as being version 5.0 REV 2012.05.06 and looking at CSWlibpqxx5-0 http : www.opencsw.org packages CSWlibpqxx5-0 on the OpenCSW website seems to indicate that this is an old unstable snapshot .

Everything was coming along nicely . I was able to SELECT from my database and so on . I then got to the stage which was most important for my code to communicate with a proprietary C++ API . My code would no longer compile with g++ after I attempted to link-to the libraries for this API . The API includes examples which I had previously compiled using CC . The examples do not compile using g++ . I figured that I d have to compile my code using CC as well instead of using g++ . My code would not compile using CC .

According to do the docs in C++11 mode it s simply using the standard-library provided by g++ 4.8.2 . Search your file system and obviously where it should be paths trying to find this to see if it s even on your system . .. . Answer : From The Docs : http : docs.oracle.com cd E37069 01 html E37071 gndfg.html .. . .. . In C++ 11 mode the CC compiler uses the g++ ABI and a version of the g++ runtime library that is supplied with Oracle Solaris Studio . For this release version 4.8.2 of the g++ runtime library is used . .. . An ABI describes the low-level details in the generated object code . Modules that use different ABIs cannot successfully be linked together into a program . This means that you must use C++11 mode on all modules in your program or none of them . So with that said you must specify --std c++11 to the linker phase too . You re not doing this presently . Comment : But iterator traits isn t even a C++11 feature is it I thought it was C++03 so I m really confused as to why it can t compile it without setting std to c++11 . I will look into posting code tomorrow . Comment : It s both . I need std c++11 to compile but when I compile with c++11 on I can t link .

For example see https : docs.oracle.com cd E37069 01 html E54439 fbe-1.html for accepted parameters . To arrive at this conclusion I started with your -v output . The key lines I saw were that it failed right after running fbe and that the error was Assembler : line 1 : Illegal flag - . I was pretty sure the line 1 part was a red herring so I went straight to the Illegal flag - part because that s exactly the error you d get if --divide was actually interpreted as -- -d -i -v -i -d -e which is a totally common way that unix programs interpret their arguments .

This is for a very large body of legacy code that I am porting to 64 bit and I d much rather put the directives in the code than in the Makefile that runs lint as the latter is quite obscure . The problem is that Solaris lint documentation specifies how to do this for only a few warning types as far as I can tell . In the past the following form was used and the Solaris documentation suggests that this is still allowed but it doesn t seem to work . Complicating the issue is that the Solaris lint does not give error numbers but rather uses identifiers like E CAST INT TO SMALL INT . Here is the old way and there are lots of these in the code already : Comment : Have you tried line -eE CAST INT TO SMALL INT just substituting the identifier for the error number Comment : Wondering if OP should suppress these warnings . Maybe post an example of code with a warning that OP would like to suppress Comment : @chux - Agreed . When porting old code to 64-bit I d think lint warnings such as E CAST INT TO SMALL INT are exactly the kinds of problems that must be fixed especially if they involve size-t and or pointer code written by someone who knows that size-t is an unsigned int .

Answer : The default ontological reasoning within Jena should provide decent validation of standard owl ontologies . The following explains how to use that same mechansism for domains that may skirt outside of what owl provides . In order to have domain-specific conflicts be generated when using the GnericRuleReasoner one needs to stimulate the generation of a domain-specific ValidityReport when FBRuleInfGraph.validate http : grepcode.com file repo1.maven.org maven2 org.apache.jena jena-core 2.11.2 com hp hpl jena reasoner rulesys FBRuleInfGraph.java FBRuleInfGraph.validate 28 29 is called . This method introduces a triple to the inference graph : .. . .. . The idea behind this is that rules within the domain will be sensitive to the existance of this triple and then generate a RB VALIDATE REPORT http : grepcode.com file repo1.maven.org maven2 org.apache.jena jena-core 2.11.2 com hp hpl jena vocabulary ReasonerVocabulary.java ReasonerVocabulary.0RB VALIDATION REPORT when a constraint of the domain fails .

We want to calculate the difference between xi and xj where xj is min x in A colon x xi . It is possible to translate this kind of expression into a Jena rule Comment : You can do math with Jena rules . You ll need to explain how you are representing the set of numbers and where you want to store the result . That said this would probably be much easier if you use SPARQL . You could use a single query to get all the results that you want and you could even use a construct query to build the results in RDF which could be added back to your model . .. . Answer : Yes you can do this in both Jena Rules and in Jena ARQ the query processing engine for SPARQL . The Setup .. . .. . Let us assume that you have defined a structured representation of your data . For Xi you have an object that corresponds to something like this N3 : .. . .. .

This would require you to construct a Jena Builtin http : stackoverflow.com a 23270901 2528639 for the nextSmallest portion of the query . The above rule would for a given value x0 within a particular set set attempt to identify the nextSmallest element x1 and if that succeeds construct a new node calculated and associate the difference with it by means of some domain-specific : hasValue property . As a style note I also introduced a : derivedFrom property in order to trace where that node came from so it wouldn t be useless as a calculation result . In ARQ SPARQL .. . .. . The first question is whether or not you want the results to be in your graph with your data as in the rule-based approach or if you simply want the results . If you simply want the results you have a choice as to whether or not the results are in a graph form . The simplest approach would be to simply SELECT the results : .. . .. . The above query was written off the top of my head so it may need some tweaks . The gist of it is that you retrieve any two members of the collection and orient them such that x0 is the smaller of the two . You then throw out the bound pairs if there exists any pair between them . The query-engine will consider the cartesian-product of the set when selecting bindings for x0 and x1 including when sameTerm x0 x1 so using FILTER x0Val x1Val provides a quick way to discard trivially poor bindings .", "Question : I succeeded in creating modifying merging ontologies with Jena API and Eclipse .

Answer : For example I want to enforce that only entities which have type x are allowed to have property y and the value of the property must have type z .

In OWL you can say that : .. . .. . propertyY rdfs : domain typeX .. . propertyY rdfs : domain typeZ .. . .. . but this does not mean at least in the way that you re expecting that only things of type X can have values for propertyY and that the values must be of type Z . What it means is that whenever you see an assertion that uses propertyY like .. . .. . a propertyY b .. . .. . an OWL reasoner can infer that .. . .. . a rdf : type typeX .. . b rdf : type typeZ .. . .. . The only time those inferences will be any kind of constraint violation is if you have some other way of inferring that a cannot be of type X or that b cannot be of type Z .

Use an OntModel with a reasoner attached and run your SPARQL updates against that graph . Then you can query the graph and see whether any inconsistency is found . How this would be done would depend on how the reasoner signals inconsistencies . This might not all that hard but remember that Jena is really RDF-based and for full OWL reasoning you ll need another reasoner that integrates with Jena e.g . Pellet but there are others too I think . 2 . Alternatively you might use a store that has reasoning built-in and probably has this kind of functionality already .

You seem to be assuming that Jena is at fault which may be the case but without seeing your data rules and code it is impossible to say .

Comment : Dear @RobV I added my rule that casues the problem and small part of the owl file where this part do not satisfy the rule condition . .. . Answer : It would help if you explained the intent of the rule as written it looks a bit odd . You start by selecting a 3 way cross products of all types so you are immediately making life hard for the rule-engine i.e .

From my understanding of Jena reasoner new inference model inf would contain statements from model as well as newly inferred statements generated by the rules . Are instances of statements in both inf and model shared or different If different wouldn t this waste memory too much An issue that I m having is reusing inferred statements into the model . Looping through inf model to find newly inferred statements and adding them to model seems to be a naive approach . Is there any other wiser method Lastly I am wondering what would be the best approach to remove outdated statement from model . What I mean by an outdated statement is probably best explained by an example . Say there is a statement Speaker hasSoundLevel 50 in the model . Later when a new statement such as Speaker hasSoundLevel 80 is inserted it should invalidate i.e . delete Speaker hasSoundLevel 50 from the model . Could this be achieved by using a rule What if a statement needs to be outdated after certain amount of time since its insertion Any suggestions on how to achieve this would be appreciated . Thanks .. . Answer : The Inferred model that is generated contains both statements from the original ontology and the inferred statements from the reasoner . As far as I am aware these statements are not shared however I do not believe it wastes a lot of memory . To find out more you may want to drop an email to the people actually working on Jena through their mailing list . As for removing outdated statements you can t directly do so through rules . You can however create a custom builtin for Jena rules that would remove statements you feed it through your rule file or use an API call on the OntModel by specifying some underlying logical conditions in your program . Again as as far as I know Jena does not natively maintain a timestamp for when a statement was added to the model so it is impossible to invalidate a statement after a certain amount of time although you could add a listener and keep a log of changes and use the log time to figure out when to invalidate .", "Question : I m trying to figure out if Jena or any other SPARQL Update server will enforce ontological constraints .

I think this is what OWL can provide but I m not sure . Also specifically will Jena ensure that if I try to write a SPARQL Update query which does not follow these rules that update will fail to insert and an error will be returned .. . Answer : What you need to understand about OWL is property restriction http : www.w3.org TR owl-ref Restriction : .. . .. . A property restriction is a special kind of class description . It describes an anonymous-class namely a class of all individuals that satisfy the restriction . OWL distinguishes two kinds of property restrictions : value constraints and cardinality constraints . .. . A value constraint puts constraints on the range of the property when applied to this particular class description . .. . A cardinality constraint puts constraints on the number of values a property can take in the context of this particular class description . Based on the description of your problem you need to use a value constraint . These value constraints exists : some someValuesFrom only allValuesFrom and exactly hasValue . For example : .. . .. . So depending on the restrictions on the individuals that you have defined these individuals can be classified by the reasoner under the right class which will be their type . The systems generally won t prevent you from entering false information but the concept will either be declared unsatifiable or inconsistent . In the case of entering an individual that is incompatible with the constants in the ontology the ontology becomes inconsistent everything goes wrong then you can retract the last fact I suppose . I am not sure about Jena but OWL-API lets you temporarily add a concept to the ontology manager and then you can check the consistency of the ontology . Normally when this check goes wrong you can remove the last unsaved change to the ontology manger via the change listener and if everything is correct you can save the changes in the ontology manager .", "Question : I have written a custom builtin to use in my Project but I do not really know how I can use it .

I still have a lot to learn about Jena and am thankful u helped me a second time . Hopefully I wont need help in the near future again . Do u want to answer the question so i can mark it as solved and give you your deserved credit Comment : I m glad this helped I ve added the essence of it as an answer . .. . Answer : First note that your rule doesn t do exactly what you ve said it does . test2 : X rdf : type NS : Test1 rightarrow .. . Y rdf : type NS : Test2 leftarrow makeSkolem Y X .. . .. . It means when a Test1 individual is found then a new blank node is created and then the type Test2 is given to that node . .. . .. . The rule matches when an instanceof NS : Test1 is found and adds a new backward chaining rule that can be used when determining whether something has type NS : Test2 : if it s the skolem of X then it has that type . It doesn t give anything the type NS : Test2 unless you ask for it . Writing the whole model of course does ask for such triples . If you find that type of behavior acceptable you could simply use a forward chaining rule that adds multiple backwards chaining rules e.g . : .. . .. . test2 : .. . X rdf : type NS : Test1 rightarrow .. . Y rdf : type NS : Test2 leftarrow makeSkolem Y X .. . Y NS : hasClassification test leftarrow makeSkolem Y X .. . .. . .. . I think that that s a bit more complicated than it needs to be . Skolem objects are simply objects that are uniquely determined by some other values so you can use makeSkolem in the preconditions of a rule as well as the head of a rule . This means that you can do this : .. . .. . test2 : X rdf : type NS : Test1 makeSkolem Y X rightarrow .. . Y rdf : type NS : Test2 Y rdf : type NS : hasClassification test .. . .. . It s worth noting that makeSkolem takes an arbitrary number of arguments . It might be worthwhile to add some sort of indicator so that you don t accidentally get the same skolem object in multiple places . E.g . if you had something like .. . .. . child rdf : type : Child makeSkolem mother child rightarrow .. . mother rdf : type : Mother child : hasMother mother .. . .. . child rdf : type : Child makeSkolem father child rightarrow .. . father rdf : type : Father child : hasFather father .. . .. . then you d actually be creating just one skolem object for each Child and calling it the Child s Mother and Father which probably isn t what you want . Instead you could do something like : .. . .. . child rdf : type : Child makeSkolem mother child mother rightarrow .. . mother rdf : type : Mother child : hasMother mother .. . .. . child rdf : type : Child makeSkolem father child father rightarrow .. . father rdf : type : Father child : hasFather father .. . .. . since child mother and child father are always different you get two skolem objects instead of just one . You might use something like this in your rule to get e.g . .. . .. . test2 : X rdf : type NS : Test1 makeSkolem Y X test2 rightarrow .. . Y rdf : type NS : Test2 Y NS : hasClassification test", "Question : Assume that I have the following statements : .. . .. .

Answer : Based on the way you have explained the problem it looks like CB40 isn t a subclass of Bike but rather an individual of type Bike . So say you have a class Vehicle a data property hasWheels on Vehicle and a boolean property canTip on Vehicle you can write a SWRL rule as .. . .. . which translates as A vehicle with two wheels can tip over . The x is any individual of the specified type . So if you create a class Bike as a subclass of Vehicle and an individual CB40 of that class and set all the relevant data properties a reasoner will assign the canTip property to true for CB40 Comment : By the way the ontology is written in Protege so it should be ok . Comment : My bad I was in a hurry when I typed out that answer and misread the code snippet . I ll edit once I am off mobile . Comment : I agree that your suggestions works but every individual must have a data property hasWheels that is what I want to avoid . I tried to express that with relations between classes . I would like to create individuals which inherit such things from their class type without explicit model for every bike that it has 2 Wheels . Is that possible" ] }	[ "yes-answer-long", "yes-answer-short" ]	semantic-web	UNK_RELATION

Comment : @Charles : The answer would almost certainly apply to anyone using portmidi whether directly through pyPortMidi through portmidi-ruby or any other simple wrapper . If the general portmidi answer didn t work in pyPortMidi that would be a bug in pyPortMidi . .. . Answer : lsusb should do the trick . All devices and their respective hubs are listed there . Comment : How do I map what I get from lsusb to the devices I have in pyPortMidi Comment : I didn t know pyPortMidi until now : I have looked into the sources and there should be something like PmDeviceInfo which has an interface interf and a name name and should be mapped to a python function called GetDeviceInfo . Maybe you can find the missing link there . Unfortunately I can t test it myself right now . Comment : So how did it go", "Question : I m trying to use pyPortMidi for an application that I build for OSX win32 and win64 . I ve gotten it to work on OSX and win32 but I am stuck trying to get it working on win64 . pyPortMidi is a wrapper for a C library named PortMidi and it is available with the PortMidi source download http : sourceforge.net projects portmedia files portmidi 217 as version 0.7 and from John Harrison s site http : alumni.media.mit.edu harrison code.html as version 0.9 . I ve tried both versions with the same failure mode . First I built PortMidi using MSVC++ 2008 Express targeted to X64 . The included test program works and is able to communicate with midi ports so I think the PortMidi build is fine . Next I built pyPortMidi . For version 0.7 I had to modify the setup.py file slightly to account for the proper location of an include files moved from . . win32 to . . pm common and it builds without errors . While version 0.7 uses cython to build pyportmidi.c version 0.9 uses pyrex to do the same thing to get it to work I had to use the version of pyrex installed using easy install . It also built without errors . I m able to import the library into Python but when I make the first call it immediately crashes Python : .. . .. . Has anyone gotten pyPortMidi running on X64 Any suggestions as to how I could debug this issue Comment : You may want to look at this question here http : stackoverflow.com questions 27737264 installing-pygame-on-64-bit-windows-7-and-64-bit-python-2-7 for a solution to this . .. . Answer : An updated pypm module is available as pygame.pypm https : bitbucket.org pygame pygame src 01b2cb16dc17 src pypm.pyx . Using win-amd64-py2.7 binaries from http : www.lfd.uci.edu gohlke pythonlibs pygame the following works : Comment : That works . I ll have to take a look at what changed to satisfy my curiosity . Thanks for the pointer Comment : I hope more people find this answer . Pygame was a small easy download and changing pyportmidi s test script from it s download not pygame s to this line gets it working right away . It was the simplest solution for getting some midi data into python and suited my needs quite well .", "Question : I m trying to talk to a Novation Launchpad with pyportmidi . I have noticed that if I just keep sending it instructions using midiOut.WriteShort it will process the first 100 or so then loose the rest . I guess that there is a buffer somewhere that is getting full and once it s full instructions are lost . I can work around the problem by adding a time.sleep .1 after each message but this obviously makes things very slow . Is there a way to test if the buffer is full and only sleep if I need to Or a way to wait for the buffer to empty before I send more data .. . Answer : When I took a look at the SVN repo I ran across this in the wrapper code note the Why is bufferSize 0 here comment. . The API documentation shows Pm OpenOutput having the following signature .. . .. . There doesn t appear to be any obvious way to find out the current buffer stack length and more importantly it would appear that the Python wrapper ignores the buffer setting entirely anyway . portmidi.c tells a slightly different tale : .. . .. . So 256 is the default . Which would explain why you re running into problems around 100 or so . However something to keep in mind - MIDI is extremely slow 31250 baud 31250 bits per second since MIDI messages are usually 2 bytes 16 bits that means a maximum of 1953 messages per second . I may be wrong here but I m pretty close if I m not right .. . .. . However there is hope : A simple fix is you can sleep down to 2ms on most operating systems without messing things up . However since you re using write short that would only give you 500 messages per second . So you might want to do something like have a queue that is polled every .002 seconds for outgoing messages pop 16 off the stack write them and then sleep . That way if your whole MIDI stack supports rates that fast you could get 8000 messages per second . I noticed that in the following code if I dropped the sleep time lower than .002 no MIDI would be sent at all until I exited the program then all the events spewed onto the MIDI BUS . So there might be an issue with portmidi rate-limiting or on OSX . One other thing to keep in mind if you re really blasting MIDI - most likely control-change values if you re modifying something like a High Pass Filter a value of 1 sounds a lot like 2 so if you make your messages less granular increment or decrement by 2 or 4 you can cut down the number of messages without having a noticeable difference in the audio . This is a suboptimal solution and in all likelihood your MIDI stack probably supports much faster than 31250 baud . Another thing to consider is that if you slave your portmidi application to the MIDI clock you can get a reliable stream of ticks from the MIDI host which you could use as the trigger to write MIDI data back out no sleeps necessary . Good luck -n .. . .. . PPQN Clock http : home.roadrunner.com jgglatt tech midifile ppqn.htm MIDI 1.0 http : en.wikipedia.org wiki MIDI 1.0 Comment : Fantastic answer thanks", "Question : I Have a console program written in C which generates short random musical compositions using the PortMidi library . Ultimately I would like to write these sequences as either a midi or audio file . I have found some explanations of reading and writing functions within the portmidi library : Pm read and Pm write but without examples I am struggling to understand and implement this . Is there anyway I can export the entire sequence at once If not is it necesary to recursively read into a buffer and save individual midi notes Or do I need to read the whole sequence into the buffer and then save it .. . Answer : PortMidi doesn t have any way to do do the whole thing in one shebang as far as I can tell so you have to manually buffer all the output MIDI messages into an array and then save them to a file . A good example of this can be found in the receive sysex function at http : audacity.googlecode.com svn audacity-src trunk lib-src portmidi pm test sysex.c .", "Question : I m using pygame.midi library to send MIDI Messages Control Change messages not notes . The idea is to send from the output from this python program to the input of another program . As you can see i m sending 0x74 124 0 . I m taking those numbers from rakarrack the application that i want to control implementation chart : http : rakarrack.sourceforge.net midiic.html .. . .. . What am I doing wrong .. . Answer : MIDI status bytes the first byte of the message must have the high 0x80 bit set . the linked chart is a bit confusing but I m guessing 0x74 is a data byte and must be preceded by the proper status byte . some basic MIDI documentation : http : www.midi.org techspecs midimessages.php .. . .. . control change is 0xbn where n is the channel number so 0xb0 is a control change message for channel 0 . Comment : Where the 0x80 comes from I don t see in the chart . Comment : I just updated with a link-to status codes . 0x80 is note off on channel 0 probably not what you want I just used it as an example . Comment : Comparing both MIDI charts I figured out that the 0x74 should be the second byte and 124 is the value of on off which replaces velocity . The question is what is the first byte value Comment : since I have no knowledge of rakarrack my guess would be a note on event 0x9n where n is the channel . 0x90 for channel 0 for example . Comment : mmmm.. . python accepted like a valid instruction however rakarrack doesn t do anything . I don t think it should be a note on event because this is not a playing device like a syntetizer or sampler .", "Question : I m doing some work with a MIDI controller called the Novation Launchpad that has a python-module available to import and use . My code keeps getting stuck on the line LP launchpad.Launchpad . So here is how I ve attempted to de-bug : .. . .. . The programme never prints I ve worked so I know my issue is in the creation of the Launchpad instance . Using a friends laptop we ve had no issues . I ve had intermittent issues with it working and not working and really don t even know where to start looking Comment : how do you know it that it is stuck in LP launchpad.Launchpad and not in LP.Open Comment : Perhaps you could hit ctrl-C while the program is apparently frozen . If the launchpad module is stuck in an infinite-loop the subsequent stack-trace could give you a hint as to where the problem lies . This is assuming that you re willing to debug third-party code . Comment : Since I don t know launchpad this is only a guess : is Open supposed to access some hardware Maybe it doesn t find it and is waiting for it to become accessible Comment : I ve also tried without the LP.Open command and that s where it seems to get hung up . Also the hardware it is using is attached and is recognisable by pygame.midi and also various DAWs . I ve tried a more complex script using the commands and it has no problems at all I m a bit stumped to be honest. . I ll post the script that runs above . Comment : Oh I ve figured it out Answer to follow : .. . Answer : So after finding a programme that would run with those commands it became clear quickly that I hadn t initiated pygame and pygame.midi .

It includes an AngularJS plugin that makes using it with AngularJS very easy but instead you ve written a wrapper of your own that hooks onto the data property of a collection something that you shouldn t do because that property is managed internally by ForerunnerDB and can be destroyed and re-created meaning you will have an incorrect reference to an object that might no longer be used by a collection . Instead you should use ForerunnerDB in AngularJS as described in the documentation : https : github.com Irrelon ForerunnerDB angularjs-and-ionic-support .. . .. . ForerunnerDB includes a helper method called ng that allows you to correctly link data from a collection to your view s scope . Also when using third party javascript libraries properties with an underscore are generally considered private and should not be accessed directly . You should use an accessor method such as .find in ForerunnerDB s case to access data instead . Usually a property that starts with an underscore is a good indication that it is private not all libraries and programmers follow this convention but many do . Comment : I am actually using the angular plugin . I ll add the app-code as well to clear the confusion . I created the service to have a smooth interface for the db that I could app-wise Did not feel comfortable using rootScope . I missed the ng helper method . Thank you for pointing that out .

Is there an equivalent library for Scaladoc If not how could I integrate this library with SBT I also considered using MathML http : www.w3.org Math but looks too verbose . Is there an editor you would recommend Does MathML integrate well with Scaladoc Thank you for your help .. . Answer : The short answer is : no . LaTeXTaglet is made possible by the JavaDoc Taglet http : docs.oracle.com javase 7 docs technotes guides javadoc taglet overview.html API . There is no equivalent in Scaladoc therefore no clean solution . However I can think of a hack that might be easy enough to do : .. . .. . There s a library called MathJax http : www.mathjax.org which looks for LaTeX-style math formulae in an HTML page and dynamically renders it in-place . I ve used it before it s pretty nice all you have to do is include the script . So you could do two things : .. . .. . 1 . Edit and rebuild the Scaladoc https : github.com scala scala tree master src scaladoc source to include MathJax or.. . .. . 2 . Write a little post-processor crawl all of Scaladoc s HTML output after it runs and inject MathJax into each file .

However this does not work if it is an object since Eclipse tries to open ObjectName .html whereas the Scaladoc-generated file name is ObjectName .html . Is there any workaround Comment : AFAIK no . In fact even inside Scaladoc itself one cannot link-to objects . If you look at the pages I wrote like Regex or the stuff inside scala.sys.process you ll see the convoluted way I refer to them instead of simply linking to them . Mind you I m not claiming Scaladoc s limitation has anything to do with Eclipse s limitation . Comment : @Daniel C . Sobral . Thanks . If it doesn t work in Scaladoc itself one can not expect it to work with eclipse javadoc mechanism . I was just hoping that if we know the mangled names of the generated class files for the objects then we can somehow trick Eclipse to open the corresponding html .

What s going on here Is this a mistake Comment : There are a lot of sort-of-duplicates on Stack Overflow that ask variants of this question about specific methods in the API . I m making this broad question with a community wiki answer in hopes that we can answer all of them in one place . .. . Answer : The incorrect signatures you re see in the generated documentation are called use cases . They re supposed to clarify the documentation by showing idealized API similar to the real one but omitting tedious details like the pervasive implicit CanBuildFrom http : www.scala-lang.org api current scala.collection.generic.CanBuildFrom parameter which bothers some people https : stackoverflow.com questions 1722726 is-the-scala-2-8-collections-library-a-case-of-the-longest-suicide-note-in-hist .

Answer : WARNING It may be a hack as I know very little about scaladoc . Since img src . . path to diagram-foo.svg is just a regular HTML you just need to copy necessary assets to the doc target path so the img resolves . You can use the following copyDocAssetsTask custom task that with doc in Compile and src main doc-resources directory gives you what you want . The point is to copy images to the directory where the documentation is generated i.e . target in Compile doc .value . build.sbt : .. . .. .

Answer : You don t need any new APIs to get the performance gains of EXI . All the EXI testing and performance measurements the W3C has conducted use the standard SAX APIs built into the JDK . For the latest tests see http : www.w3.org TR exi-evaluation processing-results . EXI parsing was on average 14.5 times faster than XML in these tests without any special APIs . One day if people think its worthwhile we may see some typed XML APIs emerge . If and when that happens you will get even better performance from EXI . However this is not required to get excellent performance like that reported by the W3C .", "Question : My requirement is to compress xml file into a binary format transmit it and decompress it lightening fast before i start parsing it .

Correct me if i am wrong . ALSO is there any good C++ open-source implementation for EXI format A version in java is available by EXIficient but i am not able to spot a C++ open-source implementation There is one by agile delta but that s commercial . .. . Answer : Nadeem .. . .. . These are very good questions . You might be new to the domain but the same questions are frequently asked by XML veterans . I ll try to address each of them . I heard about google protocol-buffers and facebook s thrift can any one tell me if these two can do the job i am looking for As mentioned by Marc Protocol Buffers and Thrift are binary-data formats but they are not XML formats designed to transport XML data . E.g . they have no support for XML concepts like namespaces attributes etc . so mapping between XML and these binary formats would require a fair bit of work on your part . OR just let me know if there is anything better then EXI i should look for . EXI is likely your best bet . The W3C completed a pretty thorough analysis of XML format implementations and found the EXI implementation Efficient XML consistently achieved the best compactness and was one of the fastest . They also found it consistently achieved better compactness than GZIP compression and even packed binary formats like ASN.1 PER see W3C EXI Evaluation http : www.w3.org TR exi-evaluation . None of the other XML formats were able to do that . In the tests I ve seen comparing EXI with Protocol Buffers EXI was at least 2-4 times smaller . I want best of both worlds best compression + best parsing performance any suggestions If it is an option you might want to consider the commercial products . The W3C EXI tests mentioned above used Efficient XML http : www.agiledelta.com which is much faster than EXIficient sometimes 10 times faster parsing and 20 times faster serializing . Your mileage may vary so you should test it yourself if it is an option . One more thing regarding EXI how can EXI claim to be fast at parsing a decoded XML file The reason EXI can be smaller and faster to parse than XML is because EXI can be streamed directly to from memory via the standard XML APIs without ever producing the data in an intermediate XML format . So instead of serializing your data as XML via a standard API compressing the XML sending the compressed XML decompressing the XML on the other end then parsing it through one of the XML APIs .. . you can serialize your data directly as EXI via a standard XML API send the EXI then parse the EXI directly through one of the XML APIs on the other side . This is a fundamental difference between compression and EXI . EXI is not compression per-se -- it is a more efficient XML format that can be streamed directly to from your application .

Only that in order to get EXI you have to get a streamwriter that writes to it or a streamreader that reads it . The most efficient way to perform EXI is StAX .

By the way EXI will become the prefered way to content-encore any XML over HTTP IMHO because of SOAP bloat - As soon as EXI settle on the browsers it could also benefit any enduser : faster transfert faster analysis best experience ever for same machine EXI does not deprecate string representation only makes it a bit different .

For those who don t know EXI : http : www.w3.org XML EXI Comment : This isn t really the place for opinion questions sorry . .. . Answer : I d personally rather not use EXI at all . It seems like it s taking all the clunky bad things about XML and cramming them into a binary format which basically removes the saving grace of XML plain text format . It seems like the general trend of the industry is moving towards more lightweight data-transfer models HTTP REST for example and moving away from heavy-weight models like SOAP . Personally I m not super excited about the idea of binary XML . Anything that claims to be the last binary standard is probably wrong . Comment : Yeah I also don t understand the point of EXI . The reason why XML is used even though it is bloated is because it is human-readable . If you take that away then XML has nothing over any other standards . Comment : Not going to downvote but also not going to agree . This is just a more efficient way to EXCHANGE the XML allowing all of the flexibility of the current format without the over-the-wire bloat . Comment : Actually EXI is just an alternative way of representing XML data where the plain text XML is the old version . It d be easy to create a bit of code that converts an XML document transferred through EXI back to a plaintext XML document considering the exact same data is contained therein . As I see it EXI removes the two major downsides of XML - size and processing speed - leaving only the good parts . Comment : I am +0 for EXI but what is frustrating are all highly-hyped claims of performance without actual external objective verification .

For those who don t know EXI : http : www.w3.org XML EXI Comment : This isn t really the place for opinion questions sorry . .. . Answer : The problem with EXI is that it needs to be abstracted from your application code . I work on a middleware product where the human-readable nature of XML is key in certain aspects logging fault finding etc . but can be sacrificed in other areas communication between internal applications to limit I O load . We currently use SOAP to for communication between or own client middleware and supplier web-applications . I would like to replace this with EXI while retaining human-readable XML in other areas . In order to replace SOAP communication with EXI I either need to : .. . .. . 1 . Wait until EXI has been incorporated into existing SOAP stacks Axis SAAJ or .. . 2 . Replace my existing Axis SAAJ SOAP client supplier implementations with my own SOAP-ish protocol on top of EXI .. . .. . The comparison between JSON and EXI is fair but the use-cases for the two are different . There is no standard for meta-data for JSON while there is XML-Schema for XML . With XML there are several standards bodies that define schemas for data exchange for specific industries . There are also a range of protocols standards that are built on top of XML such as SOAP XML-Signature XML-Encryption WS-Security SAML etc . This does not exist for JSON . Hence XML is a better option for B2B message exchange and other cases where you need to integrate with external systems using industry standards . EXI can bring some of the benefits of JSON into this world but it needs to be incorporated into existing XML APIs before widespread adoption can take place .", "Question : I am exporting large databases into xml format .

Answer : You mention protocol-buffers protobuf this is a binary format but has no direct relationship to XML . In partiular no member-names element names attribute names namespaces are encoded - it is just the data with numeric markers for identifiers . As such you cannot reconstruct arbitrary XML from a protobuf stream unless you already know how to map field 3 etc . However If you have an object-model that works with both XML and protobuf the transform is trivial deserialize with either - serialize with either . How well this works depends on the implementation for example it is trivial with protobuf-net and is actually how I do the codegen load the binary write as XML run the XML through an xslt layer to emit code . If you actually just want to transfer object data and XML is just a proposed implementation detail then I thoroughly recommend protobuf platform independent a wide range of implementations version-tolerant very small output and very fast processing at both read and write .

Answer : Compression is unified with the grammar system in EXI format . The decoder API generally give you a sequence of events such as SAX events when you let decoders process EXI streams however decoders are not internally converting EXI back into XML text to feed into another parser . Instead the decoder does all the convoluted decompression scanning process to yield an API event sequence such as SAX . Because EXI and XML are compatible at the event level it is fairly straightforward to write out XML text given an event sequence . Comment : just to confirm my understanding you are saying that there is another decoding parser by the EXI API s that just parse the decoded version just like SAX events Comment : There is no another decoding parser involved . EXI decoder does all the convoluted process integrated decompression and reverse-tokenization within itself of which the output are the events such as SAX .

For those who don t know EXI : http : www.w3.org XML EXI Comment : This isn t really the place for opinion questions sorry . .. . Answer : I m dealing with EXI right now . There s no good universal tool for processing EXI . Once you get into the guts of EXI you realize there is a bunch of needless delimiters in the binary stream which are absolutely and completely unnecessary with a schema . Some of it is humorous . How would you think the following would be encoded in EXI if both values are specified Would you think it might be maximum 4 bits 1 bit to indicate if bool1 is defined and that the value of bool1 followed by another bit to indicate if bool2 is defined then the value of bool2 Good golly no Well let me tell you boys and girls This is how it s actually encoded .. . .. . A minimum of 4 bits MINIMUM in order not to define either . Now I m being a little unfair because I m including delimiters - delimiters which are entirely unnecessary . I understand how this works now . Here s the spec : .. . .. . https : www.w3.org TR exi .. . .. . Have fun reading that It was a GREAT DEAL OF FUN FOR ME @@ @ .. . .. . Now this is just with a schema and the EXI spec specifically says that you can still encode XML that does NOT conform with a schema . Which is hilarious because this is supposed to be for small little web devices . What do you do with unexpected data that you have no provisions for handling in an embedded device Why you just die of course . There s no recovery for something you don t expect . It s not like these things have a screen I m lucky if I can log into it through a serial-port . I have used 4 different XSD generators parsers XML generators . 3 of them choke on the Schema I have to use . Data marshaling for C and C++ remember this is for EMBEDDED system with very little memory and CPU power are awful . XSD describes basically a structure or class architecture and there isn t a single tool I can find that will just create the classes . The XSD example I gave above should create a structure with a 4 bools 2 bools are the values and 2 bools indicate if they even are defined . But does THAT exist Well heck no . I like XML for describing documents . Really I do - but here is what I hate about XML - for a widely adopted standard the available tools for it are absolutely terrible . Just reading a schema is a difficult thing to do when it s spread across multiple namespaces and documents . Rant rant huff huf .. . .. . The only reason we are using this is some standards committee insisted upon it . What it s done is created a monopoly for a small group of companies that already implemented this that s the only purpose . EXI is not a widely adopted standard XML is a poor encapsulator for numeric data and it s a pain to implement it and there are no decent tools for it . EXIP is at version 5.0 - anything that works that is open-source is in Java - at least I have that . For my field of work EXI is just a bad design decision . I ve worked on tons of communications protocols on various embedded systems . I worked on DOCSIS which all modern cable modems use - they use a simple and extensible Type Length Value protocol with provisions for dealing with unrecognized types - which is why the Length is always included . It s simple it takes literally days to implement the entire stack . EXI is very difficult to hand code there are no decent processors for it and worst of all all the processors I have found that actually work well with it just transform it from EXI - XML - which is totally useless . I have resorted to writing my own XSD parser which means I have to understand at least the entire XML specification for those parts of this design that use it - and that s extensive . What would have taken me 2 weeks to do with any reasonable spec took me 10 . Nobody in my world is going to use this unless it s shoved down their throat and they shouldn t it s a square peg for a round hole .", "Question : null .. .

Encode an XML document into EXI by calling encode InputSource is method . 7 . Use EXIDecoder in org.openexi.fujitsu.proc to decode EXI into events . After instantiating EXIDecoder set GrammarCache and InputStream to it . Calling processHeader returns a Scanner and the Scanner lets you navigate through EXI . Simply call nextEvent on Scanner to get the next event until it eventually returns null . If you do not use schemas you can use null when you instantiate GrammarCache above .

Answer : I am not familiar with the two libraries mentioned but I assume that as any sane XML libraries they implement one of well-known Java XML processing APIs such as SAX Stax or DOM possibly with some extensions . This because EXI is just different encoding of standard XML Infoset so for application developer things may look exactly like normal XML processing . So you may just need to figure out API s they implement and find tutorials for using that API Comment : ....which is exactly the question I m trying to answer .

With the updated question where namespace ttml styling is used by the origin attribute of the span element the namespace is retained in the rebuilt XML but it has been moved to the span element . This is still a very valid XML document . Namespace declarations xmlns can appear anywhere in a XML document and applies to the element on which it appears and all subelements unless overridden which is very unusual . The same namespace can be declared many times on different elements . For simplicity and or optimization it is common to declare all namespaces up front on the root element using different prefixes but it is not required to do so . Comment : Edit the question .

Answer : pydoc is actually a Python script so on Windows you need to look for pydoc.py and it s not added to the Windows PATH by default so you need to give a full pathname . Try running c : Python27 Lib pydoc.py from your command-line . Edit : For a graphical interface to Python s documentation you might want to instead run c : Python27 Tools Scripts pydocgui.pyw from the command-line or from Windows Explorer . This starts pydoc s web server on your local PC so you can access the documentation through your web browser .

The popular tool to do that in Python is Sphinx http : sphinx-doc.org . But you ll need to format your docstrings in a particular format as reStructuredText .

Answer : Specifically for your case help on the re.MatchObject can be found at http : docs.python.org 2 library re.html match-objects for Python 2.x or http : docs.python.org 3 library re.html match-objects for Python 3.x . Additionally as Mark writes you can call help on the interactive console . If you don t know how to get to the interactive console you can just call python or python.exe from the command-line without any arguments . Since you are looking for help on a match object you can call Comment : Ok the language reference is further down on the page on docs.python.org 2 library http : docs.python.org 2 library .

However next level depth 2 has no subcatogories . So far I have this : .. . .. . My question if this is possible with Pomm and if yes how .. . Answer : What you want to achieve is not really possible directly because in Pomm for performances reasons when a query is performed an iterator wraps the database cursor on results . Every time a data is fetched from the iterator the converter system turns it into an entity . But entities do not know about database hence they cannot fetch more data using their accessors . A trivial idea would be to fetch a single result containing all the results as nested entities : .. . .. . But unfortunately it is not possible to use aggregate-functions in the recursive term of a CTE . Another idea would be to index results on id giving children for every parent id and using that Pomm iterators are scrollable to fetch them : .. . .. . which outputs : .. . .. . Then the result set would be ordered by parent id so iterator- get parent id would return an array of children entities or null but this looks more like a hack than a real feature .

Example i have a public schema which stores all the users details and the private schema related to each user . When user logs in the logic is to read the public schema find the private schema number and redirect the user to his private schema - how can i achieve this in POMM http : www.postgresql.org docs 9.1 static ddl-schemas.html . Inside each private schema there are multiple tables example employees general data employees salary data and so on . 2 When we have multiple schemas with same table structure employee general employee salary data we need one class for working with all schemas - now for each table POMM generates one class . Thank you for the help . Comment : What have you tried so far Comment : I tried to generate classes using of ScanSchemaTool . But it is generating classes only for one schema . I have schema1 table 1 table 2 .. . schema2 table 1 this table names are the same for all schemas table 2 I want generate classes one time for wotking with all schemas because only difference is schma name .. . Answer : By default Pomm s model manager uses each schema like a namespace and does access relations using their fully qualified-name schema.relation . The idea here is to tweak the model manager so the schema can be guessed thanks to the search path environment variable . You need a template schema where all the relations in common in all schemas are defined . Generate the models structures and entities for this schema only : .. . .. . For each Model class in the constructor just set the relation without schema information like this : .. . .. . Now in your code just set the search path environment variable like this : .. . .. .

Answer : from the link you provided .. . .. . Map classes represent a structure in the database and provide methods to retrieve and save data with this structure .

The problem was not related to how I am running the Rivr app as I was using a JEE7 app server and Injecting CDI and EJBs successfully in other places of my code . The problem was that Rivr default Dialogs are ran in a thread out of JEE or Servlet context so EJBs were not accessible even in the JNDI tree .

And to make things event more complicated there is a package javax.inject with @Named annotation .

Answer : First of all let me do some clarifications : .. . .. . Managed bean definition : generally a managed-bean is an object that its life cycle construction destruction etc is managed by a container . In Java ee we have many containers that manage life cycle of their objects like JSF container EJB container CDI container Servlet container etc . All of these containers work kind of independent they boot in application server initialization and scan classes of all artifacts including jar ejb-jar war and ear files in deployment time and gather and store some metadata about them then when you need an object of a class at runtime they will give you instances of those classes and after finishing the job they will destroy them . So we can say that we have : .. . .. . JSF managed beans .. . CDI managed beans .. . EJB managed beans .. . And even Servlets are managed beans because they are instantiated and destroyed by a container which is a servlet container . So when you see the Managed Bean word you should ask about the context or type of it . JSF CDI EJB etc . Then you might ask why we have many of these containers : AFAIK Java EE guys wanted to have a dependency-injection framework but they could not gather all requirements in one specification because they could not predict the future requirements and they made EJB 1.0 and then 2.0 and then 3.0 and now 3.1 but EJB s target was for just some requirements transaction distributed component model etc . At the same time in parallel they realized that they need to support JSF too then they made JSF managed beans and another container for JSF beans and they considered it a mature DI container but still it was not complete and mature container . After that Gavin King and some other nice guys made CDI which is the most mature DI container I ve seen . CDI inspired by Seam2 Guice and Spring was made to fill the gap between JSF and EJB and lots of other useful stuff like pojo injection producer methods interceptors decorators integration SPI very flexible etc . and it can even do what EJB and JSF managed beans are doing then we can have just one mature and powerful DI container . But for some backward compatibility and political reasons Java EE guys want to keep them Here you can find the difference and use cases for each of these types : .. . .. . JSF Managed Beans CDI Beans and EJBs .. . .. . JSF was initially developed with its own managed-bean and dependency-injection mechanism which was enhanced for JSF 2.0 to include annotation based beans . When CDI was released with Java EE 6 it was regarded as the managed-bean framework for that platform and of course EJBs outdated them all having been around for well over a decade . The problem of course is knowing which one to use and when use them . Let s start with the simplest JSF Managed beans . JSF Managed Beans .. . .. . In short don t use them if you are developing for Java EE 6 and using CDI . They provide a simple mechanism for dependency-injection and defining backing beans for web pages but they are far less powerful than CDI beans . They can be defined using the @javax.faces.bean.ManagedBean annotation which takes an optional name parameter . This name can be used to reference the bean from JSF pages . Scope can be applied to the bean using one of the different scopes defined in the javax.faces.bean package which include the request session application view and custom scopes . JSF beans cannot be mixed with other kinds of beans without some kind of manual coding . CDI Beans .. . .. . CDI is the bean management and dependency-injection framework that was released as part of Java EE 6 and it includes a complete comprehensive managed-bean facility . CDI beans are far more advanced and flexible than simple JSF managed beans . They can make use of interceptors conversation scope Events type safe injection decorators stereotypes and producer methods . To deploy CDI beans you must place a file called beans.xml in a META-INF folder on the classpath . Once you do this then every bean in the package becomes a CDI bean . There are a lot of features in CDI too many to cover here but as a quick reference for JSF-like features you can define the scope of the CDI bean using one of the scopes defined in the javax.enterprise.context package namely request conversation session and application scopes . If you want to use the CDI bean from a JSF page you can give it a name using the javax.inject.Named annotation . To inject a bean into another bean you annotate the field with javax.inject.Inject annotation . Automatic injection like that defined above can be controlled through the use of Qualifiers that can help match the specific class that you want injected . If you have multiple payment types you might add a qualifier for whether it is asynchronous or not . While you can use the @Named annotation as a qualifier you shouldn t as it is provided for exposing the beans in EL . CDI handles the injection of beans with mismatched scopes through the use of proxies . Because of this you can inject a request scoped bean into a session scoped bean and the reference will still be valid on each request because for each request the proxy re-connects to a live instance of the request scoped bean . CDI also has support for interceptors events the new conversation scope and many other features which makes it a much better choice over JSF managed beans . EJB .. . .. . EJBs predate CDI beans and are in someways similar to CDI beans and in other ways very different . Primarily the differences between CDI beans and EJBs is that EJBs are : .. . .. . Transactional .. . Remote or local .. . Able to passivate stateful beans freeing up resources .. . Able to make use of timers .. . Can be asynchronous .. . .. . The two types of EJBs are called stateless and stateful . Stateless EJBs can be thought of as thread safe single-use beans that don t maintain any state between two web requests . Stateful EJBs do hold state and can be created and sit around for as long as they are needed until they are disposed of . Defining an EJB is simple you just add either a javax.ejb.Stateless or javax.ejb.Stateful annotation to the class . Stateless beans must have a dependent scope while a stateful-session-bean can have any scope . By default they are transactional but you can use the transaction attribute annotation . While EJBs and CDI beans are very different in terms of features writing the code to integrate them is very similar since CDI beans can be injected into EJBs and EJBs can be injected into CDI beans . There is no need to make any distinction when injecting one into the other . Again the different scopes are handled by CDI through the use of proxying . One exception to this is that CDI does not support the injection of remote EJBs but that can be implemented by writing a simple producer method for it . The javax.inject.Named annotation as well as any Qualifiers can be used on an EJB to match it to an injection point . When to use which bean .. . .. . How do you know when to use which bean Simple . Never use JSF managed beans unless you are working in a servlet container and don t want to try and get CDI working in Tomcat although there are some Maven archetypes for that so there s no excuse . In general you should use CDI beans unless you need the advanced functionality available in the EJBs such as transactional functions . You can write your own interceptor to make CDI beans transactional but for now it s simpler to use an EJB until CDI gets transactional CDI beans which is just around the corner . If you are stuck in a servlet container and are using CDI then either hand written transactions or your own transaction interceptor is the only option without EJBs . If you need to use @ViewScoped in CDI you should .. . .. . use seam-faces http : seamframework.org Seam3 FacesModule or MyFaces CODI http : myfaces.apache.org extensions cdi download.html module . just add one of them to your classpath and @ViewScoped will work in CDI . MyFaces CODI has an even more solid support of @ViewScoped .. . use MyFaces CODI s @ViewAccessScoped it is an extension written on top of CDI by Apache just download http : myfaces.apache.org extensions cdi download.html it and use @ViewAccessScoped annotation instead of @ViewScoped . Use CDI @ConversationScoped and make it long running . See here for more info http : www.andygibson.net blog tutorial pattern-for-conversational-crud-in-java-ee-6 . Use Omnifaces http : showcase.omnifaces.org cdi ViewScoped @ViewScoped annotation .. . .. . Some parts gotten from here http : www.andygibson.net blog article comparing-jsf-beans-cdi-beans-and-ejbs . Comment : This is great Thanks To be complete just tell how to inject CDI or EJB bean into JSF bean . Is the @ManagedProperty someBean the proper way Comment : Nope it won t work . just turn your jsf managed-bean to CDI managed-bean by annotating it using @Named and @javax.enterprise.context.RequestScoped and use CDI injection using @Inject annotation . don t use jsf managed beans if you don t have to . Comment : JEE guys want to keep them - It s a bit more subtle than that . CDI finished rather late in the Java EE 6 cycle and both JSF 2 JAX-RS were already done . They had enhanced resp . introduced their own managed-bean facility already . Had CDI been available a little earlier things might have looked differently . In Java EE 7 JSF will adopt CDI and the javax.faces.bean will eventually be deprecated deprecation is a slow process in Java EE though which is both good and bad .

Answer : Injection already existed in Java EE 5 with the @Resource @PersistentUnit or @EJB annotations for example .

In order to get rid of the chaos in my mind I studies several articles of when to use which bean type . One of the pros for EJB seems to be that they alone support declarative container-managed transactions the famous transaction annotations . I m not sure though if this is correct . Can anyone approve this Meanwhile I came up with a simple demo application to check if this was actually true . I just defined a CDI bean not an EJB - it has no class level annotations as follows based on this http : stackoverflow.com a 6259691 1399395 snippet : .. . .. . Now the outcome on GlassFish 4.0 is that this method actually returns true which according to my inquiries is not working as expected . I did expect the container to ignore the @Transactional annotation on a CDI bean method or to even throw an exception . I use a freshly-installed GlassFish 4 server so there are no interferences . So my question is really : .. . .. . Which bean types do actually support container-managed transactions Just for the sake of curiosity how could I test it with a simple demo application if the code above is wrong BTW : Someone described a similar problem here http : stackoverflow.com questions 6908191 cdi-transactionattribute-for-bean but its solution does not apply to my case . Comment : In order to get rid of the chaos in my mind so true .. . Answer : Until Java EE 7 only EJB was transactional and the @Transactional annotation didn t exist . Since Java EE 7 and JTA 1.2 you can use transactional interceptor in CDI with @Transactional annotation . To answer your question about the best type of bean to use the answer is CDI by default . CDI beans are lighter than EJB and support a lot of feature including being an EJB and is activated by default when you add beans.xml file to your app . Since Java EE 6 @Inject supersede @EJB . Even if you use remote EJBs feature not existing in CDI the best practice suggest that you @EJB once to inject remote EJB and a CDI producer to expose it as a CDI bean .. . .. . The same is suggested for Java EE resources .. . .. . These producers will be used later .. . .. . EJB continue to make sense for certain services they include like JMS or Asynchronous treatment but you ll use them as CDI bean . Comment : Oh now I see . I did actually confuse javax.ejb.TransactionAttribute from the EJB spec which is part of JEE5+ and javax.transaction.Transactional which was added in the new JTA 1.2 spec which is now part of JEE7 . So it s great news If I got you right this might then kill off the EJB layer for mid-size applications . Comment : Yet another side note : Having transactional attributes from both JTA and EJB spec is then just another confusing DRY violation in the JEE ecosystem right Can javax.ejb.TransactionAttribute now be considered deprecated even for EJBs Comment : No because EJB are Transactional by default convention over configuration approach so it s normal you get specific annotation . Plus you can do advanced transactions stuff with EJBs like a nested transactions or manage XA transactions . But remember when you need EJB it can and should always be a CDI bean . And yes CDI can replace EJB for a light application . Comment : I see . However in my opinion they should have centralized all transaction stuff in the JTA spec and no more EJB-specific transaction handling . But let s stop discussion here . Thank you for your clarifications . Comment : I d say use @Inject only if you want to let the container automatically deal with the normally scoped life cycle all but @Dependent of a @Stateful EJB and also let the container pass around the stateful reference for you . Otherwise you might end up with illegally combined scopes CDI 1.1 section 3.2 or try to lookup a @Remote EJB which will fail without the bloated hack posted in the answer above . Looking for an EJB Use @EJB . Using @Inject makes sense only for @Stateful with a declared CDI scope .", "Question : I m working on a Java EE application primarily JAX-RS with a JSF admin console that uses CDI Weld for dependency-injection with javax.enterprise.context.ApplicationScoped http : download.oracle.com javaee 6 api javax enterprise context ApplicationScoped.html objects .

Answer : To dispel your worries : .. . .. . 1 CDI Bean inside a EJB Bean this is possible CDI EJB works pretty well together . In fact CDI will detect EJB beans and turn them into CDI beans as well . So if you create say @Stateful bean it will be picked up as CDI bean as well . That means you will be able to perform any CDI-related magic there while still having EJB features . As for choice of annotation @Singleton sounds reasonable or probably @Stateful . @RequestScoped would only live during request and die afterwards hence killing your periodic task . Choose scope based on nature of your task one bean vs many short lived vs permanent . . . Just make sure you make it an EJB bean and CDI will follow . 2 How can i add the ejb to my pom.xml Assuming you have Maven project add a dependency on EJB api the implementation will be provided by your Java EE application server . 3 If i add EJB to my project can have any conflicts Too general question I am afraid I do not know your project . But I ll go ahead and say no . At least as far as CDI and EJB goes you should be able to deal with it . Comment : Very helpful informations but a last question : Do i need a Application Server Jboss Glassfish TomEE to run EJB Can i run in tomcat7 Comment : Tomcat in a servlet and as such is not required to support EJB .

I have not done Java EE before nor do I have experience with dependency-injection so I do not understand what I should use Is @EJB and old way of injecting Is the injection done by the EJB container when using this annotation while using @Inject use the new CDI framework Is that the difference and should I be using @Inject instead of @EJB if this is the case .. . Answer : The @EJB is used to inject EJB s only and is available for quite some time now . @Inject can inject any managed-bean and is a part of the new CDI specification since Java EE 6 . In simple cases you can simply change @EJB to @Inject . In more advanced cases e.g . when you heavily depend on @EJB s attributes like beanName lookup or beanInterface than in order to use @Inject you would need to define a @Producer field or method .

Answer : Out of the box there is only the Conversation scope that gives you total control on its lifecycle . But you can create your own scope if conversation doesn t suit your needs . Creating a scope is a tough job but you can go to weld code and look how conversation was implemented .

For example suppose I have a class that currently uses an instance of Foo . I might either do .. . .. . or .. . .. . I keep reading that with CDI I can do : .. . .. . but why is this better than the previous factory based approach I assume there is some other use-case that I m not aware of but I haven t been able to identify this . If I ve understood the responses below the concept is that the DI framework acts as a master object factory that is configured centrally . Is this a reasonable interpretation Update .. . .. . I ve since started learning Spring and this now makes a lot more sense . The paragraph below is taken from Spring in Practice taking an example of an AccountService class which in turn uses an instance of AccountDao . I apologise for the long quote but I think it really gets to the heart of why injected resources offer something over standard initialisation . You could have constructed the AccountService using the new keyword but the creation of service-layer objects is rarely so straightforward . They often depend on DAOs mail senders SOAP proxies and whatnot . You could instantiate each of those dependencies programmatically in the AccountService constructor or through static initialization but that leads to hard dependencies and cascading changes as they re swapped out . .. . .. . Additionally you could create dependencies externally and set them on the AccountService via setter methods or constructor arguments . Doing so would eliminate the hard internal dependencies as long as they were declared in the AccountService by interface but you d have duplicated initialization code everywhere . Here s how you create a DAO and wire it up to your AccountService the Spring way : .. . .. . Having configured the beans as above your program can now request an instance of AccountService from the Spring ApplicationContext and the Spring DI framework will look after instantiated everything that needs instantiating . Comment : You re asking of what use is dependency-injection Comment : Pretty much . I can accept that CDI does more than my factory class as stated below but I m still not clear on what that more is . Comment : I d probably search around for general DI IoC info then . There are many advantages and duffymo s update in response to this comment sums them up nicely . For me the first three are key the fourth is just a consequence and proxies AOP don t enter into it much although I use both . .. . Answer : This is an important and subtle question about what enterprise programming is all about . The name is well chosen : contexts and dependencies . CDI has nothing to do with better or cleaner code it s about ensuring that large organizations can build complex distributed software systems and share data . It s about making 100 sure that governments or other bureaucracies can indiscriminately distribute self-contained well-documented packages for every piece of software they control . Remember that these days virtually any POJO can be injected . Let s say you re building a client app of some sort and you want it to print the first name of the user in the corner . The enterprise architects of this large company would like you to have this capability but as a junior software engineer there is no chance of you being handed the keys to the DB . They would also like to secure the data across the network but the company isn t paying any engineers to re-engineer an authentication client every time they need to share a scrap of data . They would like for you to be able to be able to query and update this info but would like transactions to be handled at a higher level than any one app . They would like for you to be able to test your classes with trivial mocks in setup blocks . They would like for coupling between classes to involve a minimum of static-methods . And on and on and on.. . Most JSRs probably have a EAs would like to be able to.. . buried inside somewhere . CDI is preferred because it allows apps of large arbitrary horizontal and vertical scales to share contexts dependencies and therefore data . .. . .. . In Fowler s words : .. . .. . The problem is how can I make that link so that my lister class is ignorant of the implementation class but can still talk to an instance to do its work . .. . But if we wish to deploy this system in different ways we need to use plugins to handle the interaction with these services so we can use different implementations in different deployments . .. . The approach that these containers use is to ensure that any user of a plugin follows some convention that allows a separate assembler module to inject the implementation into the lister . In a nutshell they allow for centralized command and control of complex enterprise applications . Java EE is a systematized reliable process for abstraction and CDI is a an incarnation of it that works so well it almost makes it invisible . It makes the stitching together of complex apps almost trivial . Two more things : .. . .. . 1 . Note that CDI exists peacefully alongside the service locator pattern known as JNDI in Java EE which is preferable if the client developer will need to choose among many identically-typed alternatives . 2 .

You can think of a resource in this nomenclature as a bridge between the Java EE 6 brand of dependency-injection @EJB @Resource @PersistenceContext and the like and CDI s brand of dependency-injection . The general gist seems to be that somewhere and this will be the root of my question you declare what amounts to a bridge class : it contains fields annotated both with Java EE s @EJB or @PersistenceContext or @Resource annotations and with CDI s @Produces annotations . The net effect is that Java EE 6 injects a persistence context say where it s called for and CDI recognizes that injected PersistenceContext as a source for future injections down the line handled by @Inject . My question is : what is the community s consensus--or is there one--on : .. . .. . what this bridge class should be named .. . where this bridge class should live .. . whether it s best to localize all this stuff into one class or make several of them .. . .. . .. . Left to my own devices I was thinking of declaring a single class called CDIResources and using that as the One True Place to link Java EE s DI with CDI s DI .

Answer : This seems highly subjective but I prefer to make several classes and I call FooProducer a class producing a Foo .", "Question : I have a full-fledged Java EE application using GlassFish Server 4.1 Java EE 7 . It is a standard NetBeans project i.e . it does not use Apache Maven .

There is a requirement to inject an EJB into a JPA entity listener as follows . This listener is present in the EE project and the class-library as well . UserService is a stateless local EJB . This works coherently unless the annotation @EJB is replaced by @Inject in which case the following exception is thrown . Is it officially disallowed to inject EJBs using @Inject in class libraries GlassFish 4.1 uses Weld 2.2.2 final as the CDI implementation . Comment : If you change the @Stateless with @Dependent does it deploy Comment : The behaviour remains unchanged if the EJB is replaced by a @Dependent scoped CDI bean the same exception is caused after applying this change . Comment : Any reason why you want to change @EJB with @Inject if it works Comment : @Gas : @Inject enjoys higher precedence over @EJB since Java EE 6 . Comment : For EJBs I find it better to use @EJB since just by looking at the code you already know what you are injecting without inspecting other classes . As you see in your case sometimes newer doesn t mean better . .. . Answer : If you fail to include a beans.xml in your application library none of the components within it will be eligible for CDI injection either as receiving injection points or as being injectable in to other components . When you added your beans.xml you made it so that your library could be injected into and its classes were now eligible to be injected using @Inject .. . .. . It s a catch 22 . The purpose of a library is that it has little outside dependency and has no knowledge of how its being used so you wouldn t typically have CDI related code in it . Comment : Isn t this behaviour very GlassFish specific or is an oversight in the CDI implementation and or CDI specification . The JPA specification states The persistence provider is only required to support CDI injection into entity listeners in Java EE container environments . If the CDI is not enabled the persistence provider must not invoke entity listeners that depend upon CDI injection . The listener in the given example is dependent upon CDI injection the Event . It is invoked when the said EJB is injected by using @EJB i.e . CDI appears to have already been enabled there . Comment : Multiple specs have stated things they can t enforce . I doubt this is a glassfish specific issue as it occurs in other containers . GF probably does it a little different since they re default is for beans.xml at the root e.g . the war in this case . Whats happening is that you re not getting any bean definitions created for EJBs in your library . Comment : Why is this mentioned in the specification https : docs.jboss.org cdi spec 1.0 html packagingdeployment.html A library jar EJB jar application-client jar or rar archive is a bean archive if it has a file named beans.xml in the META-INF directory Comment : Similar reasons .

Injecting an enterprise java bean with @EJB in an application-client launched with Java web start and from a GlassFish 3.1.2.2 build 5 server. . works as long as the requirements are fulfilled see note at bottom . But all fails if I inject something using @Inject despite whatever resource type we re trying to inject . And I know it failed because I shall get a NullPointerException if I try to use the injected resource . That tells me the annotation processor has completely forgot @Inject . Not only am I intrigued that @EJB work flawlessly at the same time @Inject does not work at all I also reason that this silent failure of the injection must be a violation of the Java EE 6 specification http : jcp.org en jsr detail id 316 . The specification says on page 69 : .. . .. . If the container fails to find a resource needed for injection initialization of the class must fail and the class must not be put into service .

My end goal. . .. . .. . . . is to separate API from implementation so that I get a much easier job trying out different implementations when it s time for performance-testing and profiling my application . However I take it this design pattern is pretty much impossible to recreate in an application-client then My immediate approach is to create new instances of all the implementations in the Main class or use factories . Of course the best solution of all would be to use qualifiers Note : Requirements for injection in application clients are that CDI must be enabled for the component package must contain the file beans.xml most likely empty if you re used to annotations and support of CDI in application clients is actually optional implementation specific . Moreover if CDI is enabled and supported then you should know that the application-client container can only be active during the boot of the client and requires thus that the resources be injected into the Main class and that the fields are static . Comment : You re trying to get a reference to a remote EJB Comment : No I m trying to get a specific implementation of an interface . Comment : As far as I am aware app client is really only applicable around remotable objects . CDI has no remoting capabilities . I doubt it something any of them are particularly thinking of since it s much easier to simply run CDI in your client than it is to try to use the app server to do this work .

Now I create a custom controller factory class class derived from DefaultControllerFactory .My goal is to make MVC use my controller factory when it tries to create a controller object . public class NinjectControllerFactory : DefaultControllerFactory .. . .. . .. . region Member Variables .. . .. . private IKernel ninjectKernel null .. . .. . endregion .. . .. . public NinjectControllerFactory IKernel kernel .. . .. . this.ninjectKernel kernel .. . AddBindings .. . .. . .. . private void AddBindings .. . .. . BO .. . ninjectKernel.Bind IAuthenticationBO .To AuthenticationBO .. . .. . DAO .. . ninjectKernel.Bind ISharedDAO .To SharedDAO .. . .. . .. . .. . protected override IController GetControllerInstance System.Web.Routing.RequestContext requestContext Type controllerType .. . .. . return controllerType null null : IController ninjectKernel.Get controllerType .. . .. . .. . .. . .. . 3 . Make MVC to use my custom controller factory . In Global.asax in Application Start .. . .. . public class MvcApplication : System.Web.HttpApplication .. . .. . private IKernel kernel new StandardKernel .. . .. . protected void Application Start .. . .. . .. . AreaRegistration.RegisterAllAreas .. . WebApiConfig.Register GlobalConfiguration.Configuration .. . FilterConfig.RegisterGlobalFilters GlobalFilters.Filters .. . RouteConfig.RegisterRoutes RouteTable.Routes .. . BundleConfig.RegisterBundles BundleTable.Bundles .. . .. . register a cutom controller factory .. . ControllerBuilder.Current.SetControllerFactory new NinjectControllerFactory kernel .. . .. . .. . .. . .. . .. . So now when MVC creates controller objects it uses our custom controller factory and as you saw it resolves all dependencies using Ninject . For example .. . .. . Ninject injects the implementation of IAuthenticationBO in our case AuthenticationBO and we can use it . Also it s very easy to use mocking and TDD but it s beyond the scope of the question . Comment : Thanks to share your method. .", "Question : I am little confused regarding this matter . I understand that VS had a SPA template for MVC4 beta but not for MVC4 RC . But http : www.asp.net single-page-application says I can install SPA with nuget-package after installing MVC4 RC .

And maybe Facebook has given up on the possibility to store data on their side via cookies altogether . You could store it on your side and relate it to the user once the log in to your app .", "Question : null .. . Answer : I am working on a website and I need a facebook-login system for users . Since I am working with NodeJs I found the passport module for authentication . I also know that facebook provides their own javscript sdk to simply login users directly from the client-side . My question is : what is the difference between these two ways of authenticating users using the facebook js sdk on the client-side and using passport facebook strategy on the server-side", "Question : This issue is very common in stackoverflow and there s a lot of different questions and answers about it yet I couldn t find exactly what I need . First I d like to define exactly what I need : the option to let users log in to my app using their Facebook credentials . The app will save a matching classic Django user .

When you go to Facebook developers you suddenly find yourself reading about some magical javascript sdk and about a promise that that s all you need . Then you get frustrated again and can t understand how a client-side related sdk can sign up users to your app . I know developers somehow implement Facebook auth packages in their apps but I just can t figure out how to do it . If anyone could tell me : at this time point what is the best way to add Facebook authentication to my Django app I would also ask for detailed documentation tutorial that explains how to log in a Facebook user from settings and configuration level through signup to Django app and to client-side code . .. . Answer : The fastest way understand FB s Oauth 2.0 flow is to play with FB s Javascript SDK . Once you get the hang of it the FB s PHP library is similar .

At the end of the process I know that the user is logged in and I know their Facebook ID . I can then register them in my database via this ID and let them use it to log in afterwards . However this seems terribly insecure . In order to let my server-side script know the user s ID I have to send it via AJAX . However I have no way of knowing whether it s the owner of the ID who s trying to log in . Anyone can send the POST request with an ID especially of one gets hold of another user s ID . My current idea is to let the user log in via JS SDK as usual send the ID and Access Token via AJAX to the server and then use cURL in the PHP script to ensure the user is actually logged in . Is this the way to go or am I overlooking better alternatives Comment : Why don t you just combine the javascript-sdk with the php-sdk as it seems you re using php as the server-side language anyway .. . Answer : 1 . You don t need to push the user s ID via ajax . You should on the server-side use the fbsr app-id cookie which holds the signed request . Parse this signed request using your secret app secret issued by FB to get the user id . NOTE : a successful parse also shows that the cookie data provided by FB is not tampered with . 2 . Once you parse the signed request you should also get the issued at time . Check that this time is within the last 10 mins . By doing this you know that the login request hit your server as the user with user id used client-side SDK . Refer : http : developers.facebook.com roadmap completed-changes .. . .. . 3 . You should immediately exchange this code for an access token . If this fails FB will give you an error message of type OAuthException it means that there was an unnatural delay between user signing in to facebook and you getting the login request . With step 2 you can thwart attempts of an attack using old fbsr cookie . If the user from user id already has an account with you then you may wish to stop here and login the user . However there may be scenarios where your app secret may be compromised . To take care of this case you should follow step 3 as the exchange of code for access token can happen only once and within 10 mins of it s issue . If the user doesn t have an account with your site then you anyway need step 3 to use the access token for retrieving other necessary user data like name email etc from FB . Therefore someone else stealing the victim s cookie and trying to attack is possible only within this 10 min security gap . If you are unhappy with this security hole you should migrate to server-side authentication . The decision depends on the sensitivity of the user information you store . And you don t compromise anything moving to server-side auth you can simultaneously continue to use client-side methods for other things .

I could make a graph call on the server-side but these are really slow so I want to keep graph calls to a minimum . Preferably only calling it at the beginning . Can any suggest an efficient secure method Comment : Downvoted as this is a dup of your last one . I ve voted to close that one rather than this as this has much more detail . .. . Answer : I know you want to avoid doing graph calls but you can make a call client-side as well and call the Facebook API : .. . .. . This will allow you to check against the logged in user s Facebook id . There s no way you can really modify anything in the javascript to fake being a different logged in Facebook user .

Comment : Surly this is no more secure as I can inject a response Comment : That s true . You can change the Facebook id within the javascript but I m not sure what that would accomplish I guess it depends on the action that you re doing .

I am able to successfully login and logout by using above . When a first time user has gone through authentication process I need to store user basic information i.e . Facebook login name email in my database . Please suggest how I can do this . .. . Answer : Subscribe to the event http : developers.facebook.com docs reference javascript FB.Event.subscribe auth.login . If you do this Facebook will call your handler after a login as happened . In that handler use FB.api http : developers.facebook.com docs reference javascript FB.api to call the Graph API to get any information you desire . For example calling me as shown in the second example will get you basic information about the logged in user . Now you have all the data in JavaScript . To send that up to your server do a plain old XMLHttpRequest AJAX request . Your JavaScript library probably makes this easy -- in jQuery this is jQuery.ajax http : api.jquery.com jQuery.ajax -- but worst case you can use XHR directly http : en.wikipedia.org wiki XMLHttpRequest . Now you have the data on your server and you can do whatever you want like store it in the database . If you only want to store the data once just check that you haven t already stored info about that user ID yet . Comment : Per @Jon Watte s answer be aware that user info sent via AJAX this way can t be trusted .

Answer : Once you ve logged in a user via the JS SDK a special cookie will be setup containing credential info encoded with your secret-key if I m correct . This info can then be used via the PHP SDK getUser method https : developers.facebook.com docs reference php facebook-getUser . As long as your API your ajax endpoint is on the same domain as your app you should receive this cookie whenever the user request your server .

Sorry because of the restriction of website domain I can t take this to fiddle . But I tried on my own domain the Facebook login window popuped in Chrome and Firefox but blocked by Safari . This is kind of weird is there anything wrong for the code-snippets provided by Facebook Developer Document Comment : It is common for modern browsers to block automatic popups automatic meaning they were not triggered by any user interaction like a click . The latter is also the recommendation only call FB.login on click . That makes it much less likely the popup will be blocked . Besides it leaves the choice whether they want to login via FB in the user s hands instead of just pushing it onto them .

BTW I ve tried user FB.login only on user click action but there are some restrictions such as the authorization code has been used error happens when user tried to login twice . Comment : Well then don t let them try to login twice FB.getLoginStatus tells you if they are logged in already at page load-time and if so don t display a login link but hello name or something instead .

Comment : It seems you have to be authenticated in facebook to use facebook Comment : Hey did you find a way to do this I m still trying to figure out how to have that page access token and call the api via PHP.. . .. . Answer : You could either use an page or an app access token but as you d be using them on the client-side neither of them are an option . See .. . .. . https : developers.facebook.com docs facebook-login access-tokens apptokens .. . https : developers.facebook.com docs facebook-login access-tokens pagetokens .. . .. . Note that because this request uses your app secret it must never be made in client-side code or in an app binary that could be decompiled . It is important that your app secret is never shared with anyone . Therefore this API call should only be made using server-side code . I d strongly recommend to build a simple server-side script PHP for example to proxy the request to the Graph API . You could then call this via AJAX for example and load the posts asynchronously and alse get rid of the FB JS SDK . There is NO way to handle this in a secure manner if you don t want to use FB Login for all of your users which also doesn t make much sense IMHO .

Comment : django-social-auth DSA from now on takes care of login registration disconnection only it doesn t offer other views templates etc that s up to the user to fulfill the user-experience desired for the site . User registration is triggered by any link button pointing to login facebook you can use url socialauth begin facebook in your templates that will create an instance of User and UserSocialAuth with Facebook access token Facebook ID . etc . Then you can call any Facebook API that your access token has rights to access . There s no explanatory flow at the moment . Comment : Thanks but this is exactly the problem - no explanatory flow at the moment . Since I m not skilled enough to make one of my one I just hope that in the future some noble soul will ." ] }	[ "yes-answer-long", "yes-answer-short" ]	facebook	UNK_RELATION

Answer : This construct will indeed fail as described when the rewrite filter runs before the authentication filter and the rewrite filter performs internally a RequestDispatcher forward https : docs.oracle.com javaee 7 api javax servlet RequestDispatcher.html forward-javax.servlet.ServletRequest-javax.servlet.ServletResponse- call on the target source . Filters listen by default on direct requests only . You d need to explicitly add the FORWARD dispatcher to let the filter listen on forwarded requests too . Or in web.xml flavor : Comment : Thank you I thought there would be a simple way to also include the forwarded pages to the filter but couldn t find it . This solved the problem I had . Comment : You re welcome .", "Question : File uploads are working for small files under the default 2MB limit but will not work for larger files . I m using JSF on Tomcat 8.0 and have modified my web.xml appropriately to increase the limit . I ve put breakpoints in the constructor of javax.servlet.MultipartConfig so I can see it reads the web.xml configuration . When the action is called though it defaults back to the default of 2MB specifically in Request.parseParts .. . the wrapper s config is null so uses the connector s default . WEB.xml : .. . .. . home.xhtml .. . .. . context.xml .. . .. . Updated After creating a simplified application it appears that the Rewrite library is causing a different container wrapper to be used in the request . Without Rewrite : Request.getWrapper returns StandardEngine Catalina .StandardHost localhost .StandardContext TestWeb .StandardWrapper Faces Servlet .. . .. . With Rewrite @URLMapping annotation : Request.getWrapper returns StandardEngine Catalina .StandardHost localhost .StandardContext TestWeb .StandardWrapper default .. . .. . So it seems that I need to configure this application s default container similar to how Faces is configured or find a way to get Rewrite to delegate to the Faces Servlet container . Editing the maxPostSize in Tomcat is an option change the default but not one I want to take if I can avoid it . Comment : You should probably remove your multipart config since the default values are what you want . See docs.oracle.com javaee 7 tutorial servlets011.htm https : docs.oracle.com javaee 7 tutorial servlets011.htm Comment : Not with Tomcat 8.0 as I understand it . Without a specified configuration the default comes from the connector s MaxPostSize which is 2MB Comment : I made a simplified application and it didn t show the same issue so I think I have a configuration problem somewhere . Comment : Seems like the issue is the rewrite library 2.0.12 . Adding just the following line to my bean causes the default 2MB to be used instead of the configured values . @URLMapping id home pattern home viewId faces home.xhtml Doesn t matter if I browser to home or to faces home.xhtml it behaves the same . In fact I can have 2 identical xhtml beans running at the same time with only the @URLMapping difference and bean name and the one without it works . .. . Answer : I don t like this solution but it serves my purposes for now . It seems like it should default to the FacesServlet s settings because that s the final destination after rewrite . My solution was to move or copy the multipart-config setting to the default servlet in web.xml :", "Question : I want to create the following scenario : .. . .. . 1 . Step : .. . .. . Login page : The user will login into the web portal . Each user has an username . For example tester12345 . This username is stored in the database . 2 . Step : .. . .. . After the redirect from the login page all pages should be in this format : .. . .. . http : tester12345.domain.com . . .. . .. . This means : username .domain.com . . .. . .. . How can I do this Comment : No websites have been seen so far that use this sort of URLs . Why not use REST like things instead in which you can meet with URLs such as those you see on this site stackoverflow.com including other sites in its network Comment : @Tiny : never seen zeef.com https : zeef.com It uses basically the same technique albeit for a completely different functional requirement . Comment : @BalusC : I visited several times but did not much concentrate on the incoming URLs in the address-bar . : .. . Answer : You would need to do something like this :", "Question : I have this rewriteconfiguration : .. . .. . Is there a way that I can map this one time I just want the .xhtml part is mapped . I thought something like this would work but it didden t : .. .

No code is very dangerous practice just search the web for something like java swallow exceptions . It is quite possible that because of implementation specifics Nokia throws LocationException where emulator does not throw it . Since you don t handle exception this may indeed crash you midlet at Nokia - and you wouldn t know the reason for that because again you have written no code to handle it . How can I catch that exception The simplest thing you can do is to display an Alert with exception message and exit the midlet after user reads and dismisses alert", "Question : I want to get longitude and latitude of the phone mobile by this code : .. . .. . The problem is that when clicking the position command then a system alert is shown saying : java.lang.SecurityException : Application not authorized to access the restricted API . So what should I do .. . Answer : add the relevant permission to your application and sign it with a certificate in the corresponding security domain . The JSR179 specification defines 7 permissions under javax.microedition.location . Choose the ones you need based on what you need your code to do . Lucifer s solution Verisign or Thawte will help if the location function group is in the trusted third party security domain for the phones you want to run your code on . The phone s mobile network operator or manufacturer might have decided to put location in their security domain instead though . http : stackoverflow.com q 1716755 contains a brief explanation of the MIDP security model . Comment : Your link answer describes how to stop those messages from emulator but you not do same thing in real device Comment : Unfortunately java-me developers usually don t have access to the security policies of real devices . All you can hope for is some documentation from the manufacturer or mobile network operator telling you what security domain a function group belongs-to Nokia documentation is decent enough . typically third party developers are forced to resort to trial and error to figure it out though . Comment : agree but final solution is Signing Certificate only .", "Question : Does anyone know how to programmatically turn off the Blackberry internal GPS receiver Comment : If you want to do this from a BB application I think you can t do it . The BB will turn of the GPS once no running application requests coordinates any more . You can only stop requesting coordinates yourself and hope that nothing else requests any . Comment : Great . Thanks for this info . .. . Answer : The best you can do is inform the system that your program is no longer interested in positions via the LocationListener interface : .. . .. . Access to the GPS is managed through JSR 179 which satisfies all location data requests and manages the GPS hardware to provide service . Comment : Thanks . Do you know how to turn it back on Comment : Is there no actual way to turn GPS off however I am really looking to do this to save battery power so the above solution wouldnt help in this case . Thanks . Comment : To turn in back on request a location either through a single location request which will allow it to go off again : locationProvider.getLocation timeout or by setting a listener : locationProvieder.setLocationListener listener interval timeout maxAge At the application level you can only limit your own program s power consumption . If the user wants to disable the GPS so that no programs can turn it on that can be done through the GPS options page .", "Question : JSR-179 is an optional package so it requires permissions and certificate signing . So are there other ways of getting longitude and latitude of mobile device through J2ME Comment : are you using S40 Series device @pheromix .. . Answer : You can connect your Device with external GPS device via bluetooth and fetch GPS details in as NMEA Strings format . You can use StringTokenizer class to fetch the lat-lon details from NMEA Strings . you can read http : www.developer.nokia.com Community Wiki How to read Location from Bluetooth GPS artical for information . One more way to your requirement is to fetch Cell-Id and based on the Google s Reverse API you can get Latitude-Longitude from Cell-Id . Comment : what if the customer cannot afford the external GPS Comment : then how can customer afford to develop such thing there should be a prerequisite decides that this kind of API will be required so you must purchase atleast this level device hence no use of developing such code . for e.g . you can not use GPRS in Nokia 1100 Comment : Internal GPS or External GPS one option he must choose otherwise no meaning of development . Nothing comes in free you have to purchase something atleast . Comment : are you using S40 Series device @pheromix Comment : Even Fetching cell-Id from some device require permissions and certificate signing . Even after that there is no guaranty of getting cell-Id .", "Question : I wrote a very simple application that asks the LocationProvider for a location and prints it to System.out .

Edit : here is my code for getting location : Comment : Please upload your code .. . Answer : You can not define the method for the location provider with the API .

Answer : the -1 timeout thing should be ok it should just go to the default . The default may be high though of if this isn t happening in the background you might want to set the timeout at something smaller like 15 seconds .

It is important for me to persists this permissions to be able to edit files after reboot of device . So according to Storage Access Framework documentation https : developer.android.com guide topics providers document-provider.html I use Persist permissions that gives the user continued access to the files through your app even if the device has been restarted . However after some time I noticed that for some users permissions were somehow revoked . Because when I am trying to use SAF for writing I get android.system.ErrnoException : open failed : EACCES Permission denied after that exception I check what permissions do I have using mContext.getContentResolver .getPersistedUriPermissions however it return empty list . I am sure that user provide me with the right permissions and that permissions are for the currently installed Sd card because I track this actions in the database . Currently in this case I am showing document picker so user can provide me one more time with new permissions but asking user to perform same action often is not user friendly . What can cause the revoke of permissions And how I can prevent this revoke I have tested on all my devices multiple reboots of the phone changing time removing inserting sd-card but was not able to lost any of saf permissions . I have next code for obtaining permissions : Comment : I use Android Storage Access Framework to access some files on SD card -- no you are using SAF to work with documents . Whether those documents are stored is up to the user not you . They could be managed by any provider Google Drive Dropbox etc . . I am sure that user provide me with the right permissions and that permissions are for the currently installed Sd card because I track this actions in the database -- the documents that the user chooses do not have to be on an SD card . What can cause the revoke of permissions -- perhaps the user deleted the file from the provider . Comment : I am using Saf only to work with files on the SD cards because of specific of app there is only reason to work with with external storage provider . I check that tree uri is in format of external storage . Comment : Perhaps the user deleted the file from the provider - it is not possible because I received the tree uri that represents the root path of external storage . There is no way to delete it . Also as I mention I was not able to create new files it was throwing android.system.ErrnoException and getContentResolver .getPersistedUriPermissions returned empty list . So user somehow revoked permissions . Comment : I check that tree uri is in format of external storage -- since there is not documented format of external storage and since device manufacturers and custom ROM builders are welcome to change Android your approach is not reliable . I received the tree uri that represents the root path of external storage -- by your own admission you do not know that since you cannot reproduce the problem . The user is welcome to choose whatever document tree that the user wants and you have no means of determining reliably whether or not it is the root path of external storage .

Comment : @CommonsWare Ok I will use ACTION OPEN DOCUMENT on Android 4.4 and higher since that s what I most wanted anyway . However the question still remains .

You have rights to use that Uri other apps do not have rights to use that Uri . .. . Answer : Edit : I have revised this answer to include the example code of approach I have initially referred to as writing a specialized ContentProvider . This should fully satisfy requirements of the question . Probably makes the answer too big but it has internal code dependencies now so let s leave it as whole . The main point still holds true : use the ContentPrvder below if you want but try to give file : Uris to apps that support them unless you want to be blamed for someone s app crashing . Original answer .. . .. . .. . .. . I would stay away from Storage Access Framework as it is now . It s insufficiently backed by Google and the support in apps is abysmal making it is hard to tell between bugs in those apps and SAF itself . If you are confident enough which really means can use try-catch block better then average Android developer use Storage Access Framework yourself but pass to others only good-old file : paths . You can use the following trick to get filesystem path from ParcelFileDescriptor you can get it from ContentResolver by calling openFileDescriptor https : developer.android.com reference android content ContentResolver.html openFileDescriptor 28android.net.Uri 20java.lang.String 29 : .. . .. . You must be prepared that the method above will return null the file is a pipe or socket which is perfectly legitimate or an empty path no read access to file s parent directory . If this happens copy the entire stream to some directory you can access . Complete solution .. . .. . .. . .. . If you really want to stick with content provider Uris here you go . Take the code of ContentProvider below . Paste into your app and register it in AndroidManifest . Use getShareableUri method below to convert received Storage Access Framework Uri into your own . Pass that Uri to other apps instead of the original Uri . The code below is insecure you can easily make it secure but explaining that would expand the length of this answer beyond imagination . If you care use file : Uris Linux file systems are widely considered secure enough . Extending the solution below to provide arbitrary file descriptors without corresponding Uri is left as exercise for reader . Comment : Also note that the filesystem path may not be usable as apps using this code may not have read let alone write access to the designated location . Comment : @CommonsWare not really . I can always detect if the the file is on external storage or copy it there myself and check that target app has READ EXTERNAL STORAGE to be sure that it will treat my file : Uri pointing to the external storage as nicely as any other . No such luck with content : . Android system content providers are lucky they generally store files in accessible locations and give it away in path but custom ones are easily screwed .

You have rights to use that Uri other apps do not have rights to use that Uri . .. . Answer : Well the solution has already been provided on the SO and you only needed to search for it .

FileUtils.java https : github.com iPaulPro aFileChooser blob master aFileChooser src com ipaulpro afilechooser utils FileUtils.java is the place where Paul Burke has written the method you re looking for . Comment : I have seen that answer but that s a lot of work to let another application handle a file selected by user . I was using the file picker provided by the Storage Access Provider to make things easier and avoid using file picker libraries . Comment : Besides this is another issue with that approach : commonsware.com blog 2014 07 04 uri-not-necessarily-file.html http : commonsware.com blog 2014 07 04 uri-not-necessarily-file.html Comment : Well I didn t recommend a file picker library and that would be off-topic . My answer or in fact Paul Burke s answer is a how-to-get file URI from various URIs . Comment : Yes I appreciate that My point is that this exercise makes the case for using Storage Access Framework very weak . It would probably be better to use a picker that directly provides a file path if getting the actual file path is the only solution to make the ACTION VIEW intent work . Comment : FileUtils hardcode file paths and other solutions for several existing file providers and check for PATH column which is unreliable to say the least see also this answer https : stackoverflow.com a 30283769 1643723 for explanation why . Any new Android version as well as slightest modification by device vendors can break those .

The issue occurs randomly but it is quite common and it is easy to reproduce on many devices . It can be reproduced on many Android 5.x devices with SD card : LG G3 VS985 4G 5.1.1 LG G Pad V500 5.0.2 Alcatel Idol 3 Nvidia SHIELD Tablet K1 5.1.1 Verizon SM-G900V 5.0 and other LG Alcatel Asus devices.. . .. . .. . Steps to reproduce : .. . .. . 1 . Install application .. . 2 . Create some files in application folder sdcard Android data applicationpackage files on SD card .

The back trace may consist of both host and device functions i.e . host and device back traces . If the application has been also compiled with host debug symbol information e.g . -g on linux then cuda-memcheck can show function names for the host functions in the host backtrace .

It s the FinishRender function I think .. . .. . Answer : If Valgrind states that a value is not initialised then in 99.5 it is really not initialised . Normally when compiler reports use of an uninitialised value -Wuninitialized in GCC you check for inline unrolls as your uninitialised value can be declared and not initialised for example 10 levels of inline function-calls or template unrolls higher than actual GCC report . Valgrind does the same but in runtime . So you should check whole path in which uninitialised value travelled from place of being declared and not initialised to the place where it s actually used . The path can be for example : cascade of function-calls where each function passes its arguments and possibly uninitialised value to next function . Valgrind will report in last function when the value is actually used . .. . .. . Generally you should not ignore what Valgrind states . Valgrind is not a simple trace program . It can be seen as a virtual-machine : .. . .. . Valgrind is in essence a virtual-machine using just-in-time JIT compilation techniques including dynamic recompilation . Nothing from the original program ever gets run directly on the host processor . Instead Valgrind first translates the program into a temporary simpler form called Intermediate Representation IR which is a processor-neutral SSA-based form . After the conversion a tool see below is free to do whatever transformations it would like on the IR before Valgrind translates the IR back into machine code and lets the host processor run it . Even though it could use dynamic translation that is the host and target processors are from different architectures it doesn t . Valgrind recompiles binary code to run on host and target or simulated CPUs of the same architecture . Wikipedia", "Question : I recently discovered the racecheck tool of cuda-memcheck available in CUDA 5.0 cuda-memcheck --tool racecheck see the NVIDIA doc http : docs.nvidia.com cuda cuda-memcheck index.html using-racecheck . This tool can detect race conditions with shared-memory in a CUDA kernel . In debug mode this tool does not detect anything which is apparently normal . However in release-mode -O3 I get errors depending on the parameters of the problem . Here is an error example initialization of shared-memory on line 22 assignment on line 119 : .. . .. . ERROR : Potential WAW hazard detected at shared 0x0 in block 35 0 0 : Write Thread 32 0 0 at 0x00000890 in ....h : 119 : void kernel test3 Data Write Thread 0 0 0 at 0x00000048 in ....h : 22 : void kernel test3 Data .. . Current Value : 13 Incoming Value : 0 .. . .. . 1 . The first thing that surprised me is the thread ids . When I first encountered the error each block contained 32 threads ids 0 to 31 . So why is there a problem with the thread id 32 I even added an extra check on threadIdx.x but this changed nothing . 2 . I use shared-memory as a temporary buffer and each thread deals with its own parameters of a multidimensional-array e.g . shared float arr SIZE 1 SIZE 2 NB THREADS PER BLOCK . I do not really understand how there could be any race conditions since each thread deals with its own part of shared-memory . 3 . Reducing the grid size from 64 blocks to 32 blocks seemed to solve the issue with 32 threads per block . I do not understand why .

This tool can detect race conditions with shared-memory in a CUDA kernel . In debug mode this tool does not detect anything which is apparently normal .

So why is there a problem with the thread id 32 I even added an extra check on threadIdx.x but this changed nothing . 2 . I use shared-memory as a temporary buffer and each thread deals with its own parameters of a multidimensional-array e.g . shared float arr SIZE 1 SIZE 2 NB THREADS PER BLOCK . I do not really understand how there could be any race conditions since each thread deals with its own part of shared-memory . 3 . Reducing the grid size from 64 blocks to 32 blocks seemed to solve the issue with 32 threads per block . I do not understand why .

The problem seems to be coming from cudaDeviceSynchronize when NBLOCKS 32 .

Comment : What value of NTHREADS Comment : @marina.k : NTHREADS is the number of threads per block here it was 32 . .. . Answer : For starters the cudaDeviceSynchronize isn t the cause your kernel is the cause but it s an asynchronous call so the error is caught on your call to cudaDeviceSynchronize . As for kernel your shared-memory is of size SIZE X SIZE Y NTHREADS which in the example translates to 512 elements per block . In your nested loops you index into it using i blockDim.x SIZE Y + j blockDim.x + threadIdx.x -- this is where your problem is . To be more specific your i and j values will range from 0 4 your threadIdx.x from 0 32 and your SIZE X Y values are 4 . When blockDim.x is 64 your maximum index used in the loop will be 991 from 3 64 4 + 3 64 + 31 . When your blockDim.x is 32 your maximum index will be 511 . Based on your code you should get errors whenever your NBLOCKS exceeds your NTHREADS .. . .. .

How are you compilling your code The racecheck tool isn t supported in SM 1.x or 3.5 docs.nvidia.com cuda cuda-memcheck index.html supported-devices http : docs.nvidia.com cuda cuda-memcheck index.html supported-devices Comment : I am using a GT 650M hence SM 3.0 .

Answer : Can you post a more complete sample It s hard to see how there would be that particular error with out some form of goto or flow changing statement . I most commonly see this error in code like the following .. . .. . This code is fundamentally incorrect . The reason why is that even though s2 has a constructor it s not executed if someCondition is true . The goto statement will jump over the initialization and at the last line of the program s2 will be uninitialized and essentially point to garbage . EDIT .. . .. .

Another common cause for this I ve just found is when you pass over some integer constants to a variadic function which are put on the stack as ints but when the callee gets it as longs you ve got a problem on 64-bit machines . I was almost about to give up and just consider valgrind being stupid then I ve realised that simply casting it to long fixes it . So my upshot is : take this messages seriously . Comment : Agreed it is incorrect to the extent that it is not legal C++ . The compiler should chuck this out before valgrind gets its paws on it .

It s the FinishRender function I think .. . .. . Answer : The error does not seem to come from your code but a library you are using . Valgrind comes with some default error suppression but that probably does not cover the library you are using . The error-checking tools detect numerous problems in the base libraries such as the GNU C library and the X11 client libraries which come pre-installed on your GNU Linux system . You can t easily fix these but you don t want to see these errors and yes there are many So Valgrind reads a list of errors to suppress at startup . A default suppression file is created by the . configure script when the system is built . You can create your own error suppressions http : valgrind.org docs manual manual-core.html manual-core.suppress that you know are irrelevant to your code .

Also I do not understand why then it refers to line 108 which is also a free . This is from the documentation Invalid free : .. . .. . Memcheck keeps track of the blocks allocated by your program with malloc new so it can know exactly whether or not the argument to free delete is legitimate or not .

Cheers Kenn Comment : I m also working on something similar - I have an open support ticket with them to clarify this process . Will answer this question whenever i get a response .. . Answer : I have a support question open with Stripe so will update as-if necessary . However I have just re-read the documentation on metered billing https : support.stripe.com questions metered-subscription-billing .. . .. . The account balance and invoice items are simply one-time adjustments to your customer s account so they won t be automatically applied each month . If your service uses metered billing or needs to add custom amounts for taxes or other dynamic costs then you will need to create invoice items every month . It continues ... . .. . .. . To get started just use webhooks to listen for the invoice.created event . Whenever an invoice is open for modification your webhook endpoint can create an invoice item that references the existing invoice s ID . We ll automatically pull this amount into the invoice total before charging your customer . So it seems we ll need to create a web hook handler in order to re-add these invoice items each month . According to the documentation on invoices https : stripe.com docs api invoices .. . .. . Once an invoice is created payment is automatically attempted . Note that the payment while automatic does not happen exactly at the time of invoice creation . If you have configured webhooks the invoice will wait until one hour after the last webhook is successfully sent or the last webhook times out after failing . That allows us to create a web hook in order to modify the invoice prior to payment being attempted . My suggested InvoiceCreatedWebhook process .. . .. . 1 . Listen for the body of the invoice.created event - the full body looks like this http : pastebin.com TyCPEDZg .. . 2 . Retrieve your customer from your database . In this example our stripe customer id is cus 00000000000000 .. . 3 . Assuming you have somehow recorded the additional items against your customer create invoice items and apply them to the invoice by setting the invoice property - in this example id in 00000000000000 Comment : I have no success with this till now and still looking for a piece of code . the tutorial from here seems helpful though 7shifts.com integrating-stripe-for-monthly-payments https : 7shifts.com integrating-stripe-for-monthly-payments Comment : I think adding the invoice items from your webhook event-handling code is the best general solution . If you only have a few plans variants you could also create all possible permutations as separate plans in Stripe . E.g . you d have the 1 Cookie w Ice Cream plan the 2 Cookies w Ice Cream plan etc . That could get ugly quick if you increase your number of plans and options though .", "Question : Is it possible in stripe payment .. . .. . First we will validate credit-card using stripe then we generate token and create customers . we will save token instead of credit-card information in database and later we will make payments from customers on basis of token or customer instead of credit-card information . In javscript file how do we handle stripeResponseHandler and function stripeResponseHandler status response because we have already generate token using .. . .. . in payment step how we call stripeResponseHandler .. . .. . Please understand the requirement .. . .. . 1- Save the Token by verifying credit-card information in this case no payment is involve . amount price will zero 0 . 2- Save this Token in your database but this token is use once not many time.If use this Token later it will not work . 3- Create customer will create a customer at stripe.com and we can also save in our database but the reason is that we will not recharge from our site we have to login at stripe.com and recharge from that site . when we recharge from that site we are unable to save records of that in our database.Also at time of creating customer we have to create a recharge for latter . we also need credit-card again if we use this client . so this is the main issue . 4- we can make own function stripeResponseHandler because through stripeResponseHandler verification of cards can be done at stripe.js at stripe server . Comment : Each time we need a new token for payment through credit-card information This example stripe.com docs tutorials https : stripe.com docs tutorials charges saving-credit-card-details-for-later will just create a customer in stripe.com and we use this user id.. . This need amount but in our case first we verify credit-card and save token and later after 1 day 1 month or any time make payment from that user account . .. . Answer : In Stripe in order to save a card or bank account to charge later you have to create a customer then add payment sources card or bank account to that customer . Once you create a customer with a payment source or sources you have 3 options to create a charge . 1 . Charge the customer using default source : Stripe : : Charge.create amount : 1000 currency : usd customer : cus xxxx .. . .. . 2 . Charge the customer using a credit-card : Stripe : : Charge.create amount : 5000 currency : usd customer : cus xxxx card : card xxxx .. . .. . 3 . Charge the customer using a bank account : Stripe : : Charge.create amount : 8000 currency : usd customer : cus xxxx bank account : ba xxxx", "Question : So I went through the trouble of implementing a Stripe payment system in my app and submitted the app for review a few days ago . My app got rejected and Apple notified me that you have to use the In-App Purchase API for any payment system . This just doesn t seem right - why does Stripe even have an iOS SDK in that case Comment : I m voting to close this question because app-store submission policy is off-topic for Stack Overflow https : meta.stackoverflow.com q 272165 65839 and better addressed by Apple support . .. . Answer : You can use Stripe in an iOS app . Apple accepts it when the customer can buy something which is not digital . for example your Instagram pictures printed on a mug a computer and so on . But if you use Stripe for something like a subscription like a gold access to a revue or to buy credits for a game Apple will refuse the app and force you to use In-app purchase . take a look here : .. . .. . There are a couple different ways to integrate payments into your iOS app : Apple Pay and In-App Purchases . It s important to understand when each option should be used . .. . You can use Apple Pay to sell physical goods such as groceries clothing and appliances . Also use Apple Pay for services such as club memberships hotel reservations and tickets for events . These transactions will be processed through Stripe and you ll only need to pay Stripe s processing fee . You can read more about Apple Pay here . .. . You are required to use Apple s In-App Purchase API to sell virtual goods such as premium content for your app and subscriptions for digital content . Specifically Apple s developer terms require that the In-App Purchase API must be used for digital content functionality or services such as premium features or credits . If you use the In-App Purchase API the transactions will be processed by Apple which will charge a fee of 30 of the total transaction . https : support.stripe.com questions apple-and-stripe-tos-and-fees hope it helps", "Question : As I have saved stripe customer id s in my db for later payments . here customer will have multiple cards where I would like to check validate customer card with existed cards from that particular customer .

So correct syntax would now be : .. . .. . Hope this helps someone", "Question : I need to find the best solution for automated payments into bank accounts . My scenario is that we have funds in a bank account which can be registered a provider account like paypal or stripe if needed . When a user submits a request for money i need to automatically send that amount to their bank account from our bank account or payment provider account . Is there a way to automate it needs to be able to support most european bank accounts . .. . Answer : Through PayPal there is not a way to do that with the request money feature . The request money feature is there for the specific purpose of requesting money from a particular user . If you were able to do that then there wouldn t be stopping someone from constantly requesting money from you and you just pay them whatever that amount is . I would assume this is also not possible with Stripe because having this capability is a HUGE risk on the merchant and payment processor end . A better way to do it is by using Mass Payments https : developer.paypal.com docs classic mass-pay integration-guide MassPayOverview mark mass 20payment through PayPal to schedule payments to a mass number of users . This does require approval from PayPal so you will need to contact them to get it enabled . Comment : i believe that the Paypal Mass Payment requires the receiving users to also have paypal which in my case they might not . Comment : Stripe offer a beta for UK users called Managed Accounts which kind of covers what i m trying to do only problem is its a beta at this moment . Comment : Yes that s correct the Mass Pay does require receivers to have a paypal account . All the transactions in paypal have to hit their account first before it can be withdrawn . Comment : Did i understand that correctly You want it to where if a buyer just requests money from you you automatically pay them I cant imagine that you would want something like that . I mean technically you could have a script to scan your email and then make an API call to pay that buyer . Comment : I don t want to be bound to the user having a paypal account because we receive payments from multiple sources bank transfer stripe and paypal . Ideally a system which offers an automated way to make bank transfers is what i am looking for", "Question : Background .. . .. . I m trying to integrate stripe-payments into my site .

You should write to Stripe s support directly if you have more questions about this : support.stripe.com email https : support.stripe.com email . Comment : Uf that is some time .

Answer : For PayPal look at the following . DoReferenceTransaction https : developer.paypal.com webapps developer docs classic api merchant DoReferenceTransaction API Operation NVP - This will allow you to hit somebody s credit-card to process an amount without authentication so long as you ve done a prior Authorization or Sale using the same credit-card . So you could have people run an Authorization on their card just to ensure it s good and get a transaction ID that you can use in future DRT requests . DoNonReferencedCredit https : developer.paypal.com webapps developer docs classic api merchant DoNonReferencedCredit API Operation NVP - This will allow you to load funds onto a credit-card without referencing any previous transaction so it s different than a refund . Keep in mind that when you send somebody money this way you won t get refunded fees like you would if you used the actual RefundTransaction https : developer.paypal.com webapps developer docs classic api merchant RefundTransaction API Operation NVP API so you may want to consider that . You ll want to go through the detailed documentation for Reference Transactions https : developer.paypal.com docs classic express-checkout integration-guide ECReferenceTxns of course to get a good understanding of it . You ll also need a Payments Pro https : www.paypal.com us webapps mpp referral paypal-payments-pro partner id UHALZ2245EDV6 account to be able to process credit cards directly and utilize these features . If you happen to be working with PHP I d recommend using my class-library for PayPal http : www.angelleye.com product php-class-library-paypal . It ll make the API calls very simple for you . Comment : Nice Thanks .what about Stripe Comment : Stripe makes you wait 7 - 10 days or more for your money . That could cause issues with what you re explaining you re trying to do I would think . Comment : i read from stripe doc they transfer fund only in USA any other cool payment gate way that allow me to transfer funds through CC to CC Comment : are you sure we can transfer funds to customer DoNonReferencedCredit have nothing param to transfer Comment : DNRC allows you to push funds to a credit-card from your PayPal account ." ] }	[ "yes-answer-long", "yes-answer-short" ]	api	UNK_RELATION

Answer : Backing up the other users you will need to run Virtual PC instances on your Windows box . If you try to do a multi install of Internet Explorer you will break conditional-comments on pages which will make testing difficult anyway For example With Internet Explorer 5 6 and 7 . On a Windows box the IF Internet Explorer statements will resolve to Internet Explorer 7 even in Internet Explorer 5 which means even more weird bugs .

Using mydebugbar suggested by Tom for IE6 has worked well enough though I use VMs now . .. . Answer : Microsoft does not support multiple versions of Internet Explorer on one operating-system . The reason is that the operating-system and Internet Explorer share certain DLLs . When you upgrade from Internet Explorer 6 to Internet Explorer 7 or Internet Explorer 8 you re actually replacing some system DLLs . This is the reason why you get Internet Explorer 6 when you uninstall Internet Explorer 7 . Chris Wilson Internet Explorer architect addressed this issue in a blog post Multiple IEs on one machine http : blogs.msdn.com cwilso archive 2006 02 01 522281.aspx . Chris states that on-the-fly replacement of mshtml.dll might work for CSS rendering ...but it s not the same as having a full set of new Internet Explorer system DLLs installed and would certainly not be considered a definitive solution . del Only virtualization can provide the full DLL stack for definitive testing . del .. . .. .

Answer : Nobody mentioned this but IETester http : www.my-debugbar.com wiki IETester HomePage is a great tool . It supports Internet Explorer 5.5 6 7 and 8RC1 .

Answer : TLDR : Apache Karaf is much more batteries-included . It can also run on any OSGI runtime . Apache Felix which is an implementation of the OSGi 4.2 framework .. . .. . Sort of . Apache Karaf can use Apache Felix . Apache Karaf can also use Equinox or another OSGi runtime . By default the Apache Karaf standard download does come with Apache Felix . Apache Aries which is an implementation of the Blueprint standard .. . .. . Again sort of . The standard download of Apache Karaf does come with Apache Aries by default . Now let s talk about what OSGI Apache Felix Equinox is and what Apache Karaf is : .. . .. . OSGI is very simple . You can start an OSGI runtime in your application and not even notice it . The shell the ability to hot deploy from a folder install from a maven repo etc..These are all extras that OSGI doesn t have to do and are provided by additional projects like Karaf GOGO or Pax .. . .. . Now on to Apache Karaf : .. . .. . It is basically an OSGI environment that provides some additional goodies on top of a standard OSGI implementation . Because Apache Karaf is just built on standard OSGI it can in theory run on any OSGI runtime . This gives you a uniform interface for working with OSGI runtimes . Some goodies Apache Karaf provides that you won t see in a Apache Felix without some additional work : .. . .. . Folder based hot deployment .. . A IMHO better default console than gogo . org.apache.karaf.shell .. . Remote SSH access to that console . org.apache.karaf.shell.ssh .. . Centralized Logging System . org.apache.karaf.log .. . It has it s own way of provisioning bundles and start levels . org.apache.karaf.features .. . Karaf has it s own maven plugins as well . Pretty much anything here : .. . .. . http : mvnrepository.com search.html query org.apache.karaf .. . .. . I mentioned Karaf having it s own way of provisioning bundles and start levels . Apache Karaf also comes with a bunch of pre-defined ones to get started with . I know Apache Felix comes with some as well through OBR but Apache Karaf comes much more batteries-included .", "Question : Started working on a new project and We are using Apache Karaf for running OSGi bundles . Some one suggested me to use Equinox instead of Felix inside Karaf . Please some body let me know if Equinox is better than Felix and if so what way . .. . Answer : A few years ago there were some stability issues that lead folks to recommend Equinox over Felix . Today I recommend using Felix since a good number of the Karaf ServiceMix committers also have the ability to make changes to Felix without having to wait for Equinox to make upstream changes . Latest check of Equinox website also seems to indicate that it is lagging Felix+Karaf a bit in terms of adopting the latest OSGi Enterprise specs .", "Question : Apache Karaf http : karaf.apache.org is a sub project of Apache Felix http : felix.apache.org . It is defined as a lightweight OSGi container . I don t understand when should I use the heavyweight and when to use the lightweight . Their site doesn t explain this too much . .. . Answer : The lightweight OSGi container label is contrasting Karaf http : karaf.apache.org with more feature rich OSGi containers not with Felix http : felix.apache.org . To quote Guillaume Nodet Karaf s author from here http : gnodet.blogspot.com 2009 04 apache-karaf.html : .. . .. . Felix is just the OSGi core runtime . Karaf provides a distribution based on Felix by adding other features such as a console an SSH remoting mechanism a file deployer and more . In this diagram of the Karaf architecture Felix or other OSGi implementation - currently Equinox http : www.eclipse.org equinox is also supported is the OSGi box the other boxes are the features added by Karaf : .. . .. . Karaf Architecture https : unpocodejava.files.wordpress.com 2010 09 image00210.png Therefore unless you have specific needs which are not met by Karaf requiring access to the underlying implementation it usually makes sense to use this since it provides more out of the box . Comment : Thanks . That clears the confusion : Comment : Thanks great and clean explanation . Comment : One nice feature of any OSGi container is that you can select just the bundles you need and deploy them into your container . So my advice would be to first architect your application and then pick what you need . The advice to just install the whole platform because it is feature rich sounds a bit like going back to the huge Java EE application servers . Now I m not saying that Apache Karaf is anywhere near as big as those I am just making a point that you can and should just deploy what you actually need .", "Question : I am a little bit confused about what Apache Karaf exactly is .

Answer : Apache Karaf is a swiss army knife to run OSGi stuff and non OSGi things bundled as OSGi . Felix and Aries are default but the frameworks are pluggable so equinox works as well . Unix like shell accessible from CLI or SSH .. . Hotdeploy of bundles .. . May deploy almost anything as a bundle plain .jar spring xml blueprint etc .. . WAR files .. . Deploy from maven - including autowrapping non OSGi bundles . Web Console .. . Karaf features - .kar files that includes bundles and custom karaf features commands . A side note is that Karaf is part of ServiceMix the initial name was ServiceMix kernel so it has very tight integration with Apache Camel Apache CXF and Apache ActiveMQ . Turning Karaf into an ESB with those features is trivial .", "Question : In OSGi the resolution process of defined dependencies i.e . Package imports and exports is pretty strict when using version numbers and version ranges . If for some package import of version 1.2.3 no corresponding export with a range containing 1.2.3 is found the bundle cannot be resolved or started . This is good . However this does not seem to apply to the core package org.osgi.framework .

Answer : No package imports in OSGi are NOT repeat NOT treated differently . OSGi never makes exceptions for its own services or code it is completely symmetric .

FYI i have taken the opendaylight karaf distribution . nexus.opendaylight.org content repositories https : nexus.opendaylight.org content repositories opendaylight.snapshot org opendaylight integration distribution-karaf 0.4.0-SNAPSHOT . .. . Answer : The bundle leveldbjni has a dependency on a native library . Native as in os dependent . In OSGi a bundle can declare several natives libraries and specify for each library when this library can be loaded . In your error you can see which library this bundle can load : .. . .. . windows32 leveldbjni.dll if processor x86 osname Win32 .. . windows64 leveldbjni.dll if processor x86-64 osname Win32 .. . osx libleveldbjni.jnilib if processor x86 osname macosx .. . osx libleveldbjni.jnilib if processor x86-64 osname macosx .. . linux32 libleveldbjni.so if processor x86 osname Linux .. . linux64 libleveldbjni.so if processor x86-64 osname Linux .. . .. . In your case osname Windows 8.1 so there is no library matching this name and the requirement fails . Each OSGi framework has a list of alias for mapping osname-s . It depends on your implementation and versions . For example the latest version of Equinox https : github.com eclipse rt.equinox.framework blob master bundles org.eclipse.osgi container src org eclipse osgi internal framework osname.aliases has this configuration : .. . .. .

Answer : We re using Karaf for a number of our applications . We were already using Camel JMS and Esper for integration between several different platforms a JBoss 4.2 instance a Tomcat and several Felix instances and as this was working well there was little justification in migrating this too which would have been cause to consider ServiceMix . The only reason we have some Felix nodes is that they re limited in use on client desktops rarely need get updated and I wanted the smallest footprint for these nodes . For anything OSGi on the serverside we re using Karaf . Karaf provides all of the features you d expect and need for a production environment see the apache-karaf tag s info http : stackoverflow.com tags apache-karaf info . We do our development and testing against standard minimal framework using pax-exam but deploy to Karaf . If you don t need an ESB JCA BPEL etc but want a solid tunable OSGi container then Karaf on it s own is more than adequate . And if you found yourself needing a limited subset of ServiceMix s functionality you can always install these in a Karaf instance . You can also customise the Karaf distribution http : karaf.apache.org manual 2.2.2 developers-guide custom-distribution.html as part of a maven build - personally I like have the container as part of the application s build as I can checkout build and run the entire setup from the command-line in minimal time . Recently there s a clustering subproject of Karaf called Cellar http : karaf.apache.org index subprojects cellar.html using HazelCast I not sure if this applies to ServiceMix too . Comment : +1 for the detailed response...thanks", "Question : Chapter 126 of the OSGI Enterprise Release 5 specification http : www.osgi.org Download Release5 mentions compatibility : .. . .. . Support the traditional JNDI programming model used by Java SE and Java EE clients . and use of OSGI-unaware code : .. . .. . Clients and JNDI Context providers that are unaware of OSGi use static-methods to connect to the JRE JNDI implementation . The InitialContext class provides access to a Context from a provider and providers use the static NamingManager methods to do object conversion and find URL Contexts . This traditional model is not aware of OSGi and can therefore only be used reliably if the consequences of this lack of OSGi awareness are managed . but it is not clear to me if this text only applies to legacy code executed inside an OSGI bundle or also to code outside the OSGI container f ex in a scenario where the OSGI container is embedded in an application . In an embedding scenario there may be application code both outside and inside the OSGI container that performs JNDI calls and as they execute in the same JVM they will share JNDI implementation . Question : Should an OSGI JNDI implementation running in an embedded OSGI container allow OSGI-unaware code outside the container to perform its JNDI calls like usual or is some porting to OSGI-awareness required Trying this out myself with Apache Karaf 2.3.0 which uses Apache Aries JNDI 1.0.0 this doesn t seem to work as Apache Aries requires JNDI client calls to originate from an OSGI bundle . Partial stacktrace : .. . .. . Question : Is this correct behaviour or is there a section of the specification I can refer to that is violated by this limitation .. . Answer : I ran into same issue when trying to deploy Apache Karaf on Weblogic . We use karaf through a servlet bridge - a war is deployed in weblogic which bridges all http requests to karaf . I am running with the the following applications on weblogic : .. . .. . 1 . app1 uses JNDI .. . 2 . app2 .. . 3 . karaf-bridge bridges requests to Karaf .. . .. . As soon as karaf starts the Aries JNDI implementation running inside Karaf sets InitialContextFactoryBuilder inside javax.naming.NamingManager to its own implementation . NamingManager holds a static reference to the initial context factory builder so whichever implementation irrespective of whether its running in an OSGI environment sets this static reference becomes the JNDI provider . In my case-when app1 non-OSGI tries to do a new InitialContext Aries JNDI tries to resolve it using the BundleContext and fails . I fixed this using some very ugly hacks that involved extracting the javax.naming package from jre and installing it as a bundle in karaf . So the answer to your question : I think the issue is really in the jre and not with OSGI on how JNDI lookup is managed .", "Question : I am getting uses constraint violation as below while installing a feature in Apache Karaf karaf framework is felix and version is 4.2.1 .. . .. . could not be resolved .

Thanks in advance .. . Answer : If you use the felix framework this should be printed either on the console and or in the logfile while starting the bundle .

Is there any way to upgrade this felix to latest 4.6.0 bundle : tree-show and dependency chain gives the same information Comment : Actually there shouldn t be any need to upgrade to a newer version as the one used in Karaf 3.x is already up to-date .

It is defined as a lightweight OSGi container . I don t understand when should I use the heavyweight and when to use the lightweight . Their site doesn t explain this too much . .. . Answer : @Marcel Karaf isn t monolithic or huge like a Java EE server . It is a very slim and minimalist implementation . It is a core product without much functionality other than a basic console file loading so that you can actually read configuration-files etc . The latest zip file of it is 19.1 MB . Yeah . Small . It can easily run on small devices and work in embedded . What you may be thinking of is something more like ServiceMix which uses Karaf as a core kernel . But it includes CXF ActiveMQ Camel and other libraries in its full configuration . Even then they have minimal medium and full sizes . Really for 99 of the projects out there it wouldn t make sense to start directly with Felix and not use Karaf instead .", "Question : I am trying to use Karaf and I was wondering if it is possible to configure it to pull the transitive dependencies from the Apache Maven Central repository .

I also know you can use OBR to read from a repository.xml file in a deployed site but I can t find one for Maven central .

At the moment my work around is to figure out what the dependencies are and explicitly add them to the .. . .. . Embedded bundles do not work with the Karaf OSGi blueprint implementation it just waits for something that won t exist . I also find it ugly to have to do that . Another possible answer I can think of for this question is if there were instructions to create a package that can be deployed to any OSGi container not just Karaf using KAR files that contains all the necessary dependencies . .. . Answer : As far as I know the best you can do is use Maven to download all the dependancies and then use the Felix bnd plugin http : felix.apache.org site apache-felix-maven-bundle-plugin-bnd.html to convert your local or remote repository into an OBR that you can use with Karaf . Comment : Any example of how to do this conversion Comment : @ArchimedesTrajano The link I provided goes into some examples . It s basically a matter or setting up the pom file with some additional details again see the link and then running mvn clean install or mvn clean deploy Comment : I did see the link earlier on and the examples only show how to install the bundle for the pom in question it does not show you how to include the transitive dependencies .

One is to use The OSGi Bundle Repository OBR another is to use Features in Karaf and the third is to use Karaf Cave http : karaf.apache.org index subprojects cave.html . I m not really sure how these options are really different . They all seem to be doing the same things . Are they just different implementations of the same functionality Could someone please explain the differences or provide some recommendations .. . Answer : Karaf features and OBR are different ways of solving the sort of same problem . Both allow you to install OSGi bundles into an OSGi framework but how they decide which bundles to install is different . With a Karaf feature you provide a file feature.xml say which explicitly lists URLs for all the bundles for the feature . They can live on the filesystem or in a maven repository or anywhere else which can be described by a URL . OBR on the other hand works out what bundles to work out based on requirements and capabilities . It will work out the transitive dependencies of whatever you re installing as your starting point and make sure they all get installed . Usually you d configure one or more external repositories which support the OBR format and then an OBR resolver in your runtime would provision bundles from those repositories . So you can say I need package org.foo or I need an OSGi service which implements org.bar and the provisioner will decide which bundles best suit your requirements . OBR is more flexible and generic than Karaf features but it might be overkill if you re just installing a well-defined set of bundles into a framework which is already primed with the infrastructure you need . It also doesn t help you if the bundles which make up your application don t have dependencies on each other - you ll still need to include them all in your starting set . The distinction gets a bit blurred because Karaf features allow you to specify version ranges in the maven URLs so even with a feature you can be a bit flexible in what gets provisioned . Karaf features also have an interoperability with OBR so you can write your feature definition file in terms of OBR requirements . I believe Karaf Cave is an OBR implementation with some feature-features . So it s a server rather than a new technology like features or OBR provisioning . -- Enterprise OSGi in Action : http : www.manning.com cummins Comment : self-advertising the right way good answer thanks", "Question : I got this error when I tried to deploy a bundle that uses Compendium service : .. . .. . My bundle is configured so it uses : .. . .. . And acording to karaf 4 depts documenation http : karaf.apache.org index documentation karaf-dependencies karaf-deps-4.0.x.html . Osgi Compendium version is 5.0.0 . Does this means that I need to provision to karaf compendium jar manually is there any karaf feature contain Compendium Services .. . Answer : The compendium and core jars contain the OSGi APIs . They are only to be used at build time . Do not install these into OSGi . The core APIs are all implemented by the OSGi framework bundle . The compendium as well as the enterprise API bundles contain too many different APIs to be useful at runtime . If you install them they can cause trouble by conflicting with other API versions installed . Instead you need to provide a bundle that implements the API . This bundle then either embeds the API package it implements or you additionally need to install an API bundle that contains only this API package . In you case you need to install the scr feature which implements the declarative-services spec . Comment : Hi Christian I am working on a UPnP OSGi implementation . So far I was installing the osgi-compendium.jar manually included in my feature .

Answer : Karaf s life started as the ServiceMix core . Currently ServiceMix is really a set of bundles that are deployed into a Karaf container . ServiceMix has a number of very handy bundles which do a lot of cool stuff that karaf doesn t . That said the two primary reason for using ServiceMix is if you want : 1 an ESB 2 NMR a feature that allows you to community between bundles AND instances of Karaf . This all said the ServiceMix group is currently planning version 5 which will remove the ESB and NMR features and will be focused on being a management container for Camel . In ESB s a great deal of effort when into creating components that could be described using BPL Business Process Language . However the folks that wrote ServiceMix began to focus on the implementation of EIP s Enterprise Integration Patterns which largely does the same stuff as BPL but does it in a more standardized and accepted manner . This work was done under the Camel project . So in short . If you are using ServiceMix 4+ you re also using Karaf . If you want a more robust integration environment the environment of choice today in the Apache Felix world at least is Karaf Camel and a few bundles from Servicemix . Comment : Does Karaf come with a SOAP engine for web-services I know I can add CFX to get that . I m wondering if that comes with ServiceMix .", "Question : null .. . Answer : Good day . I am trying to get the benefits of OBR in my application . I took Karaf Cave 4.0.0 as OBR implementation and org.apache.felix.bundlerepository 2.0.4 as OBR client . I successfully configured the repository itself but I can t properly use it . The problem is : when I install the bundle via OBR and all its dependencies are already installed in OSGI runtime it is installed successfully . But if some of the requirements are missing I got an Unsatisfied requirements error which is odd since I know for sure that all the resources which resolves these requirements are present in the OBR descriptor and all links to them are valid . Why aren t they resolved automatically How to configure OBR client to work with Karaf Cave I also tried OBR implementation from Sonatype Nexus OBR plugin and found out that the OBR descriptor generated by Cave and the one generated by Nexus are differ . Moreover : .. . .. . the one generated by Cave is OSGI compendium spec compliant .. . the one generated by Nexus is not but works like a charm with org.apache.felix.bundlerepository - the problem is not reproduced . I am completely confused . The step sequence to reproduce the problem reproduced on Apache Karaf 4.0.0 : .. . .. . 1 Installing Karaf Cave : .. . .. . 2 Creating a cave repository : .. . .. . On this step I am able to successfully retrieve an OBR descriptor from http : localhost : 8181 cave http test-repository.xml .. . .. . 3 Install the OBR client and register test cave repository from Karaf : .. . .. . 4 Try to deploy some OBR resources with obr : deploy Comment : I have the same problem with a vanilla Felix 5.4 installation . Trying to obr : deploy a bundle from my repo fails with Unsatisfied requirement s unless I first deploy its dependencies located in the same repo . My repo also uses the OSGi Repository Specification format as opposed to the proprietary Felix OBR format .", "Question : I have two features that are using antlr4-runtime but different versions of it . In runtime classes for antlr are loaded from 4.5.3 version for both features . Can we configure karaf somehow to use one version of same library for one feature and the other for second feature .. . Answer : There is no need to do explicit configuration for the Karaf container . While constructing a bundle you need to mention the specific versions antlr bundle in the consuming bundle the one which uses . Since karaf OSGi container accepts deployment of same bundle with different versions . This is one of the major advantage of OSGI containers .", "Question : I am trying to use Karaf and I was wondering if it is possible to configure it to pull the transitive dependencies from the Apache Maven Central repository . Without having to use embedded bundles .. . .. . I already know you can pull explicit dependencies the key part of the the question is the transitive ones . I also know you can use OBR to read from a repository.xml file in a deployed site but I can t find one for Maven central . A possible answer to the question would be to add the URL but I can t find it documented anywhere what the repository.xml URL is . At the moment my work around is to figure out what the dependencies are and explicitly add them to the .. . .. . Embedded bundles do not work with the Karaf OSGi blueprint implementation it just waits for something that won t exist . I also find it ugly to have to do that . Another possible answer I can think of for this question is if there were instructions to create a package that can be deployed to any OSGi container not just Karaf using KAR files that contains all the necessary dependencies . .. . Answer : You can use the karaf-maven-plugin to create a feature file from maven dependencies . This will resolve transitive dependencies . Comment : again I ask for an example when I did this yesterday I just get NullPointerExceptions . Also my question text explicitly states that I am looking for something that will work in ANY OSGi container not just Karaf Comment : Can you post your sample project somewhere I can then take a look at it and check why you get a Nullpointer exception . This could mean that there is a bug somewhere . As far as I know there is no container independent answer to this problem . Please also check that you use the most current version of Karaf . For an example you can look at the karaf source code in assemblies features . It uses the karaf maven-plugin to create its own features . Comment : github.com trajano maven-jee6 tree emerging-technologies https : github.com trajano maven-jee6 tree emerging-technologies hello-osgi Comment : actually for container independence I would think OBR would do it but I haven t found a way to create an OBR repository with the transitive dependencies just specific bundles .

We re trying to avoid using devenv.exe setup since in rare cases this may cause extensions not to load as detailed by Remco Mulder on the MSDN forums http : social.msdn.microsoft.com Forums en-US c483d83f-d640-4fe9-8ff7-af78d635df23 visual-studio-extension-caching-preventing-extensions-from-loading forum vsx . 3 . We still need to perform post-installation operations currently not possible with VSIX . 4 . Due to previous sins we hardcoded some of the paths to use the CompanyName ProductName Version format that the VSIX packages used to follow but it seems that VSIX randomy generate a folder name now as Jason mentions in his answer below . So what I d essentially like is to be able to install an unpacked VSIX package - have the MSI installer create the file structure on disk in the correct location VSInstallDir Common7 IDE Extensions Company Product Version and then somehow to have VSIX consume the .vsixmanifest file to register the extension in Visual Studio . Initial digging into the Extension Manager API shows there s a method called CreateInstalledExtension in ExtensionManagerService that takes in a path to vsixmanifest in assembly Microsoft.VisualStudio.ExtensionManager.Implementation.dll but unfortunately it is internal . So without resorting to API hackery is there any alternative way to essentially install an extension in Visual Studio 2012 and above without using devenv setup Comment : If you set InstalledByMSI true InstalledByMSI in the source.extension.vsixmanifest and then unpack the files from the .vsix file to the Extensions folder does it work if you omit the call to devenv setup Comment : Yes our vsixmanifest has InstalledByMSI set to true . Per Ed Dore s blog in VS2012+ extensions are not being re-cached by default blogs.msdn.com b dsvst archive 2012 10 08 http : blogs.msdn.com b dsvst archive 2012 10 08 your-vs-package-may-not-load-after-porting-it-to-vs-2012.aspx Comment : Is it possible to launch the VSIXInstaller.exe quiet vsix path instead of unpacking the VSIX manually Comment : @280Z28 I m currently looking into that . There s an issue with a randomly generated folder name as Jason mentions in his answer below.. . it doesn t seem to be using the company product name . .. . Answer : As Jason and everyone else suggests - yes the correct supported way of registering a Visual Studio package externally is by running devenv.exe setup and for the most part - it works without problems albeit slow due to entire Visual Studio configuration being rebuilt . This is a commercial product and every once in a while we get a support case complaining that after installing our extension something bad happened in Visual Studio - other extensions failed to load problem with Solution explorer etc . Those cases are rare but they do happen . In an attempt to minimize the impact installing our extension does to the user s machine I was trying to find a suitable way to use the VSIX installation mechanism that does not use devenv.exe setup but unfortunately there isn t a supported scenario that handles all the issues I ve raised in the question above . After extensive research into the problem I found http : blogs.clariusconsulting.net kzu how-to-install-a-visual-studio-extension-with-templates-via-an-msi an undocumented unsupported solution that solves the problem completely An empty file called extensions.configurationchanged located under VSInstallDir Common7 IDE Extensions gets touched http : en.wikipedia.org wiki Touch 28Unix 29 every time a VSIX package is installed or uninstalled causing Visual Studio to refresh it s package cache only on next restart With modifying this file s last modified date it will essentially cause Visual Studio to act as-if a VSIX package was just installed or uninstalled . A few quick experiments of copying the extension files to an empty hive and then touching the extensions.configurationchanged will cause Visual Studio to load the extension and process all its .pkgdef files on next restart - no devenv setup necessary Several commercial products offer this solution in the Troubleshooting section of their online help dealing with loading failure of their extension so this solution might be the lesser evil I was looking for .

Answer : There s something called the User State Migration Tool that is intended for preserving state in corporate PC desktop deployments for wipe-and-load similar to your Azure scenario .

The most offending ones especially the extensions with their Uninstall button disabled grayed out in VS are perfectly safe to remove - they even warn if something else depends on them so no worries there either .

My VSIX shows up in the Online section of Extensions and Updates in Visual Studio 2012 and I can install it from there : VSIX available to install from Online http : i.stack.imgur.com Q1rja.png .. . .. . However once it s installed I can t figure out how to update my extension in a way that makes it show up in the Updates section of that same dialog box nor can I figure out how to make Visual Studio notify me that an update is available . VSIX doesn t appear in Updates pane even though it s a newer version than installed http : i.stack.imgur.com lX315.png .. . .. . I ve tried various combinations of the following : .. . .. . 1 . Increasing the version number in the VSIX itself and in the atom.xml .. . 2 . Changing the updated tag inside of the entry tag to the current date and time .. . 3 . Changing the updated tag inside of the feed tag to the current date and time .. . 4 . Changing the published tag inside of the entry tag to the current date and time .. . .. . My expectation was that a combination of 1 2 and 3 should be enough to show that there is an update but to no avail . This guide http : msmvps.com blogs p3net archive 2013 01 11 hosting-a-private-visual-studio-gallery.aspx seems to confirm my expectation : .. . .. . Published - The date time when the extension was added . Updated - The date time when the extension was last updated . I ve also tried all 4 at the same time also to no avail . I m serving the gallery from an Apache instance and I ve confirmed that it s setting a correct Last-Modified header for the atom.xml . Is there some interval at which Visual Studio checks for updates Does opening the Updates section of Extensions and Updates not force Visual Studio to check Here s the contents of my atom.xml : .. . .. . I should also note that my extension is not Strong Name Signed because it uses a third party assembly that is unsigned . Does that make a difference .. . Answer : I had the same Issue and made some deep investigation . In my case it was odd that my extension always shown as Download in the Private Gallery instead as Installed the Green Hook . So I guessed there is a missing Link between the Gallery item and the installed Item .. . .. . The answer is as simple as annoying : .. . .. . The ID has to be THE ID . So the Product ID in the VSIX Configuration is the reference which has to be in the Atom-File . In Your case : .. . .. . As you see : Withyout your MyVSIX. . . After that it will recognize your Extension and if installed also hide the Download Button within the Gallery .. . .. . For Update : .. . .. . It s enough if you increase the Version Content . For The Update Cycle my experience : .. . .. . It checks on start of the Visual Studio once Daily if in Option enabled .. . It checks every time you open the Extensions and Updates . So reopen after a save of the XML should be enough . EDIT : thanks for the Upvote .. . .. . Here the Pictures for better understaning made in VS2013 but almost same for VS2012 .. . .. . The ID in the VSIX File . VSIX ProductID http : i.stack.imgur.com rarbZ.png .. . .. . How it should look like in the Atom-Feedfile . How it should look if you correctly linked between Gallery and VSIX File . Gallery Linking http : i.stack.imgur.com 7e1Dn.png Comment : Thank you so much that worked Just to be clear we are talking about the Id element inside the Vsix element . Comment : Thanks for your feedback . I ve added the VSIX Tag in the exmaples to clarify the location . Comment : Oh man this had bothered me for over a year . Thank you Comment : You saved my day thanks . Comment : Great - thank you Still wondering why the heck Microsoft placed the name of the Extension + . . in front of the id in their guide for private galleries https : msdn.microsoft.com en-us library hh266717.aspx", "Question : null .. . Answer : I m using Visual studio 2015 inside our organization . I want to be able to use the Extensions and updates features but I always get a connection problem when I try to access the online or update section . We are behind a proxy server . The problem is related to the configuration of the proxy because the feature work well if I connect my pc on a direct internet-connection . The proxy is managed by another organization and I don t know much about that subject . I need help on what I should say so they understand what they need to change . Does someone knows what configuration need to be put in-place to make that VS feature works thanks Comment : There might be something about the route is using . The update are using the http protocol and also the news . The extensions are using the https 443 protocol . Visual studio seems to be using the IE proxy config file for the update but not for the 443 . It s using a different route . maybe this is what is causing the problem . Is there a way to force Visual studio to use IE proxy config file wpad file .", "Question : We have a Visual Studio extension currently installed with MSI since we need to perform certain tasks after the installation ngen registering certain COM servers etc . In the end of the installation we run devenv.exe setup more specifically devenv.exe setup nosetupvstemplates to make it a bit faster to register the extension in Visual Studio 2012 and above in 2010 this step was not required since VS2010 would rebuild the extensions cache on every startup . We re currently looking to move to a partial VSIX installation but there are certain issues : .. . .. . 1 . We have a certain folder structure additional bundled tools . I wasn t able to find an option to include arbitrary folders and files with in VSIX package . Is this possible 2 . We re trying to avoid using devenv.exe setup since in rare cases this may cause extensions not to load as detailed by Remco Mulder on the MSDN forums http : social.msdn.microsoft.com Forums en-US c483d83f-d640-4fe9-8ff7-af78d635df23 visual-studio-extension-caching-preventing-extensions-from-loading forum vsx . 3 . We still need to perform post-installation operations currently not possible with VSIX . 4 . Due to previous sins we hardcoded some of the paths to use the CompanyName ProductName Version format that the VSIX packages used to follow but it seems that VSIX randomy generate a folder name now as Jason mentions in his answer below . So what I d essentially like is to be able to install an unpacked VSIX package - have the MSI installer create the file structure on disk in the correct location VSInstallDir Common7 IDE Extensions Company Product Version and then somehow to have VSIX consume the .vsixmanifest file to register the extension in Visual Studio . Initial digging into the Extension Manager API shows there s a method called CreateInstalledExtension in ExtensionManagerService that takes in a path to vsixmanifest in assembly Microsoft.VisualStudio.ExtensionManager.Implementation.dll but unfortunately it is internal . So without resorting to API hackery is there any alternative way to essentially install an extension in Visual Studio 2012 and above without using devenv setup Comment : If you set InstalledByMSI true InstalledByMSI in the source.extension.vsixmanifest and then unpack the files from the .vsix file to the Extensions folder does it work if you omit the call to devenv setup Comment : Yes our vsixmanifest has InstalledByMSI set to true . Per Ed Dore s blog in VS2012+ extensions are not being re-cached by default blogs.msdn.com b dsvst archive 2012 10 08 http : blogs.msdn.com b dsvst archive 2012 10 08 your-vs-package-may-not-load-after-porting-it-to-vs-2012.aspx Comment : Is it possible to launch the VSIXInstaller.exe quiet vsix path instead of unpacking the VSIX manually Comment : @280Z28 I m currently looking into that . There s an issue with a randomly generated folder name as Jason mentions in his answer below.. . it doesn t seem to be using the company product name . .. .

Answer : in principle the advantage with the Neo4j embedded version is the great Rails3 and performance boost you get by not being forced to do REST . However Heroku does not provide a permanent fiel system which is why the Neo4j addon is operating over REST and thus Neography is a good choice for you .", "Question : I m trying to write an importer script that will take a MySQL resultset and add nodes and relationships in my Neo4J DB .

I want to create a node with Application label with the application id amount application date fields and another node with Account label with account id field and a relationship between them . My SQL query is from the applications table so I m not afraid of dups there but an account id can appear more than once and I obviously don t want to create multiple nodes for that . I m using neography but willing to switch if there is something simpler .

Should I or should I not define the constraint on Account Many thanks It s my first time with graph DBs so apologies if I miss a concept here. . .. . Answer : From what you describe it looks like you should use the constraints that come with Neo4j 2.0 : http : docs.neo4j.org chunked milestone query-constraints.html constraints-create-uniqueness-constraint .. . .. . CREATE CONSTRAINT ON account : ACCOUNT ASSERT account.account id IS UNIQUE .. . .. . Then you can use the MATCH . . CREATE UNIQUE clauses for all your inserts . You can use neography to submit the cypher queries see the examples here : https : github.com maxdemarzi neography wiki Scripts-and-queries Comment : do you know if there is any syntax in neography that does match and create unique Or I have to use execute query Comment : Use the execute query with your cypher query as a parameter .

Is this impossible while using Neography If so what could be my possible alternatives which don t involve JRuby i.e . using neo4j.rb . .. . Answer : Neography is a wrapper to query a neo4j server through the REST protocol . In that case you should be able to query from anywhere you want once you have started the server even with a simple curl command . You want especially to uncomment this line in conf neo4j-server.properties if your apps are on 2 different servers : .. . .. . Make sure however to protect your database you can read here how to : http : docs.neo4j.org chunked stable security-server.html", "Question : I am experimenting using Neography with Rails 3 and can t quite understand where to specify DB connections Model Validations validates presence of etc . The examples available for Neography does not have one for Rails . Would appreciate any pointers . .. . Answer : I don t think Neography integrates that closely with rails or has an ActiveRecord mapper . You can find configuration information on their wiki https : github.com maxdemarzi neography wiki Configuration-and-initialization : they don t explicitly say it but you should copy that config in to initializers neography.rb . In regards to Models specifically in regards to the Neography gem you re probably best off storing data in normal Postgres Mysql sqlite and using after create after update after delete hooks in your models to then keep the neo4j database in sync . If you do it this way you really only have to store the minimum amount of data needed in Neo4j e.g . object ids and only the data your actively using for node and vertice graph operations . Then when you query neo4j you d take the resulting object id s and rehydrate them by querying your SQL ActiveRecord models .. . .. . The alternative is to use the Neo4j gem https : github.com andreasronge neo4j itself which offers ActiveRecord mappers and a much cleaner api . But I assume that you re not doing that because of environment constraints for example you want to run on Heroku and use the Neo4j addon Comment : Thanks . The only reason I was considering neography was that I am not a super duper Java guru and hence was unsure of using JRuby Neo4j . Since I don t want to use multiple DB s I am now going to give it a go .", "Question : I m trying to implement a rails application with neo4j . For hosting I found that Heroku supports neo4j REST public beta . Looking for gems I found neography and neo4j . I started with neo4j and didn t find support for REST . Is it possible to work with REST Is there any benefits to go with embedded database If I go with neography can gems like devise be used in the project .. . Answer : I think you only need neography if you re using MRI Ruby . If you use jruby you don t need to use a restful server and according to the docs your neo4j queries will run faster . Devise will work fine with jruby although you will find other gems don t work well with Neo4j eg declarative-authorization or cancan since they rely on ActiveRecord and Neo4j only satisfies ActiveModel . If you do end up using jruby I strongly recommend you use rvm to install it and don t forget to add the --1.9 flag when running ruby or run export JRUBY OPTS --1.9 since jruby 1.6 defaults to ruby-1.8 which is not immediately compatible with Rails 3 . Sorry I can t answer your question about the REST client .", "Question : I m new to working with Neo4j and the neography gem . I m building an API that will require authentication . I m used to using Devise or Clearance with Postgres to handle authentication . If users are stored as nodes in the Neo4j database are Devise and or Clearance compatible with Neo4j Or will I need to implement my own authentication .. . Answer : If you re using Neography you ll need to roll your own authentication . Neography does not have the concept of models that Devise looks for . If you re used to auth gems devise-neo4j https : github.com neo4jrb devise-neo4j works with Neo4j.rb https : github.com neo4jrb neo4j to provide Devise support . Since you re planning on using Neography Neo4j.rb might be a bit heavier than you re looking for . You could use it for a single User model for auth and then the underlying Neo4j-core gem for basic more direct Neo4j communication . Comment : Ah looks like you re one of the maintainers of neo4j.rb http : neo4jrb.io . Honestly I don t know much about neography I just started with that one . I m assuming you prefer neo4j.rb more than neography How would you compare them Comment : My gem preference always comes back to requirements of the project there s a tool for every job .

Does Neo4j keep some form of queue for the batch insertions and insert it over time If so how can I see the progress of this queue I am doing a count and I notice the records are increasing but at a very slow pace .

Running Neo4j 2.1.2 enterprise edition on Ubuntu 12.04 LTS . .. . Answer : Did you shutdown the batch inserter correctly after finishing your insert Which Neo4j version and OS are you using Also make sure your memory config is correct . Configure the memory-mapping fore the nodestore and relationshipstore correctly see Rik s blog post http : blog.bruggen.com 2014 02 some-neo4j-import-tweaks-what-and-where.html for that . It is not a queue it is writing those records directly . How do you check and count You must not access the database concurrently .

Neo4j Enterprise 2.1.2 on Ubuntu 12.04 LTS . I m checking the count via match m : User return count .

So if you can rewrite my above codes in native Neography code it will be greatly appreciated . .. . Answer : I don t know Neography but I can take a shot at answering question 1 since that appears to be answerable by changing your third Cypher query . Since your 2 initial queries seem to be getting the node IDs for user 1 and user 2 you should be able to avoid searching again for those nodes by using the START clause . You will need to specify a parameter map with the 2 node IDs returned by the first 2 queries . Comment : Yeah but I think even querying using ids will take some time to search along the index tree . I am thinking that given I have done the query once if it is possible to store the exact object for reuse such as creating a pointer pointing to the fetched users or a variable storing the object . Put aside Neography if it is possible using Cypher Comment : I think specifying a node by node ID is as close as you can get to a node pointer", "Question : How do I update a given property of a node using neography And if its an indexed field . will the indexes get updated automatically I know on the console its as trivial as .. . .. . Of course this doesnt update any indexes indices sp either . Comment : Just found the set node properties method in neography . Must ve missed it earlier . But it still doesnt update the indexes .

To update an index entry the old one must be removed and a new one added .. . .. .

I m using RoR 3.1.1 with the neography gem . I currently have a neo4j graph of people nodes with relationships as friends connecting them . Given a specific person s node I d like to page through results of their friends-of-friends 2nd degree nodes 5 at a time . Right now I use the following traversal code which gets me ALL of the friends-of-friends at once it can take so long that it will cause a timeout : .. . .. . From the neo4j website http : docs.neo4j.org chunked stable rest-api-traverse.html rest-api-creating-a-paged-traverser it looks like there is already such a thing as paged traversals but I don t see any references to doing this from neography . Could someone provide example code to show how to do this with neography if possible how to do it without neography if necessary or a work-around such as limiting the number of results returned from the example traversal I m already doing Thanks .. . Answer : Could you use a Cypher query for this http : docs.neo4j.org chunked snapshot cypher-query-lang.html like .. . .. . for the first 5 friends Comment : Thanks This seems to mostly work with a few quirks . I think it s returning both the original node as well as some direct friends . Perhaps it s returning some direct friends who are also connected through another friend but I thought this query should exclude direct friends Also it seems to return no results nil when I specify a RETURN field that doesn t exist . Is there a way to say return this field if it exists otherwise return the results with nil for that field E.g . .. . - fof RETURN fof.uid fof.name fof.birthday SKIP 0 LIMIT 5 Comment : I m still wondering about it returning direct friends as well but I fixed the issue with return fields that don t exist using the operator : e.g . .. . - fof RETURN fof.uid fof.name fof.birthday SKIP 0 LIMIT 5 Comment : After more investigation I found a way to fix the issue of it returning both the start node and direct friends while preserving the friends-of-friends that it returns . I m marking your answer as accepted thanks Here s the cypher query I have working with those extra tweaks : start n node 1 match n - : friends - friend - : friends - fof where not n --fof and n.uid fof.uid return friend.uid friend.name fof.uid fof.name fof.gender SKIP 0 LIMIT 5 Comment : Great that s exactly the way ." ] }	[ "yes-answer-long", "yes-answer-short" ]	ruby	UNK_RELATION

The xhost program is used to add and delete host names or user names to the list allowed to make connections to the X server . On your Fedora box you would type xhost +mywindowsbox to allow the xclock and emacs and whatever else on the windows box to be displayed on the Fedora X screen . However this only gives you the Windows emacs on the Fedora screen editing the Windows file . If you are looking to use the Fedora emacs on the Windows file you may want to set the Windows box to share its files and use samba on Fedora to make it accessible by an emacs running on the Fedora box .", "Question : I am developing a JSF web application on a Windows box using Emacs as my editor but I far prefer to use Emacs in a Linux environment .

Answer : First of all I m not very used to linux so I ll try to explain all my steps carefully . Sorry if this is a long post . I have a server with Xubuntu 14.04 and I want to connect remotely to a graphical session . After trying VNC and XRDP I have chosen XDMCP as stated in this page : https : wiki.ubuntu.com xdmcp - It s the best by performance and security is not an issue for me personal LAN . The other ones didn t work well for me and were unstable but that s part of another post in the future . I want XDMCP to work as I want . I have edited etc lightdm lightdm.conf added XDMCPServer enabled true line and restarted . Everything works ok and I connect from Windows with Xming with this line : C : Program Files Xming Xming.exe -query 192.168.1.101 -clipboard . I have also tried with the launcher from XMing choosing 0 as the Display . As I have said XDMCP works as expected fast and responsive . My problem is that I need a permanent session opened as-if I were connecting to a VNC or XRDP session . For example let s say I open Firefox with a page I close XMING and when I reopen XMING later I want to return to the same desktop . Everytime I close XMING all the programs in that session are closed and I have to reopen them . This is a serious issue because I can t leave anything long on background doing anything it closes everything and I have to restart it . I have searched for documentation or other people with the same problem and I have found nothing . Maybe the problem is that XDMCP is not planned to work like that I haven t found an answer yet .

Comment : That s a very ad-hoc solution . It s easy to manipulate simply editing the startup script for the guest user and make it log passwords and undoubtedly confusing when things don t work right .

Answer : It s possible to set up a ix to remote display to a system you re sitting in front of without an X server on the machine running the app . You need X11 libraries one or more X11 applications and you probably want openssh set up for remote X11 forwarding - all on the raspberry-pi .

Once the express app is running a file is selected and uploaded via an HTML multipart form-data form and the output from the node server is : .. . .. . Has anyone any ideas what is causing the error and how to fix .. . Answer : The problem lies in the fact that you aren t piping just a file request to gridfs-stream . Using Multer as a middleware with catch any multipart form-data post request . As the stream comes in Multer built on Busboy https : github.com mscdex busboy watches for the on field and on file events and parses accordingly . What you are piping to Multer is not just a file . This bit of code works fine because Multer has indeed parsed out for you req.files and req.body by this point : .. . .. . But where your code runs into problems is here for reasons mentioned above : .. . .. . I have yet to find a way to stream a multipart form-data post request with more than just file uploads straight to GridFS . If your post request doesn t contain anything other than the file meaning no other html-input fields in the form then you might want to consider removing Multer from the middleware at least for this route . For my use-case I require the ability to receive an html-form-post with text inputs along with the file-upload I store metadata about the file on upload . Here is how I accomplished what I needed with Multer : .. . .. . By default Multer will store your files on disk . One quick solution is to just create a readstream and stream it right back into GridFS . Once the writing is completed remove the tmp file . As a side note there seems to be some thought going around that it s best to use Multer as middleware only on the routes that need it . You can read more on that thought on the last section of this http : lollyrock.com articles express4-file-upload . Update .. . .. . I think I am close to finding a way to stream directly to GridFS with metadata by use of Skipper https : github.com balderdashy skipper . I m in the process of seeing if I can t get some updates going to skipper-gridfs https : github.com willhuang85 skipper-gridfs that will take the text inputs on the html-form and set those as metadata etc . The tweak to the skipper-gridfs seems pretty minor . I ll update when that gets flushed out . If you look at skipper be sure you recognize the order of your html-form inputs if you have any does matter .

Answer : Like Sasikanth said you can fix the problem with piping and that s the best approach . But if you are wondering what s wrong with your current approach then I suggest to read the Buffer https : nodejs.org api buffer.html documentation.You are naming your variable as buffer but assigning string . Then in your data callback you are adding string with Buffer . When you do that the chunk buffer is converted to string using it s toString method . So your binary-data is converted to utf8 encoded string and here it goes wrong . Since utf8 is multi-byte encoding the output size becomes large I don t know the exact mechanism of this conversion .

In my situation I have legacy code where we use GUIDs in MongoDB UUID as identifiers . Best Practices for UUID Data in MongoDB http : 3t.io blog best-practices-uuid-mongodb .. . .. . I have a problem with getting a file from GridFS by UUID . I use new MongoDB.Driver.GridFS package and use GridFSBucket class . I would like to get stream by UUID not ObjectId but I can see that all overloads of DownloadToStream XXX methods have take ObjectId as parameter . There is no overload for UUID . So the question is : Is there any way to convert safely UUID to ObjectId and try to get the file from MongoDB Any help will be appreciated . Adam .. . Answer : The latest version of the GridFS spec requires that the id for a stored GridFS file be of type ObjectId . But since there may be existing files stored in GridFS where the id is not an ObjectId there is an overload of DownloadToStream that takes a BsonValue id . Since there is no BSON type for GUID specifically any GridFS files you might have where the id was originally a GUID would actually have the id stored as either a BsonBinary value or a BsonString value depending on how you chose to represent the GUID in MongoDB . So to read an existing GridFS file that was stored using a GUID as the id you need to convert that GUID to the appropriate BsonValue and then pass that BsonValue to the DownloadToStream overload that takes a BsonValue id .", "Question : I am using the following code to read the image file saved in MongoDB using GridFs : .. . .. .

I think you use it as a route in express app . So send will be called before your post request completed .

Answer : I realized that its been a while and its a problem some of you may encounter and the solution was not really what I posted in the comments as I found more problems later . The issue that we had was that the java servlet that we were posting the multipart form-data was not able to handle chunked data and setting headers won t do you any good . using request library will not help you here .

Will it be necessary to pass from the new Windows App Store as it happens for iOS or will I be able to distribute the .exe without passing from Microsoft .. . Answer : As far as I aquired information . There are assumptions that the standard Surface have no Desktop mode . That means the pad will be purely comparable with Android and iOS . The Pro version will instead also be delivered with desktop mode also . In normal terms full Windows 8 . If that s the case you can install and run Metro specific applications on Standard or better described Applications developed under WinRT . But with Pro version also windows desktop applications like classic Office and such . UPDATE .. . Based on a few QA from Microsoft they are going to make differences in Windows 8 versions . They are going to offer distribution of apps outside the store . This is an extremely important point in example to business line use and intranet purpose . Though they are about to make this available to an Enterprise version of Windows 8 . ..Only the Enterprise version of Windows 8 will have the capability to Side Load Apps . Side loading bypasses the Windows Store to install custom Enterprise Apps within an organization. . .. . .. . I feel the answer is a little of Yes you are able to distribute the apps outside the store and No for public or world wide use you have to go through the Windows Store . As a distributor it appears to be a work-around . Though the recipients of this side-loaded app have to be aware of that work-around . This is a citate from Microsoft Developer page .. . .. . Preparing other PCs Some business users might not use a PC that supports enterprise sideloading . Common reasons for this are that the edition of Windows that their enterprise uses doesn t support this or the IT admins do not manage the PC . This scenario is becoming increasingly common with the growing trend of personal devices used for work . .. . To enable sideloading of a Metro style app onto a PC : Set Group Policy for Allow all trusted apps to install . If you cannot use Group Policy then you can set this through the following setting : HKEY LOCAL MACHINE Software Policies Microsoft Windows Appx AllowAllTrustedApps 1 Verify that the app is signed by a CA that is trusted on the target machines Activate a special product key by using a script on the target machine to enable sideloading . We ll go into more detail about how the IT admin will acquire the product keys in an upcoming blog post . The product key only needs to be install and activated once on the PC . From link : http : blogs.msdn.com b windowsstore archive 2012 04 25 deploying-metro-style-apps-to-businesses.aspx .. . .. .

How to do it Do I have to retarget my project to Windows 10 Comment : Please un-accept my answer as I would like to delete it . If you look at the comments there is some controversy about whether it is correct . I apologize for any trouble . .. . Answer : Windows 10 users can download Windows 8.x and Windows 10 apps from the store . Windows 10 mobile users can download Windows Phone 7 and Windows Phone 8 apps as well . Basically anything that was available for Windows 8 will still be available for Windows 10 . Anything that was available for Windows Phone 8 will still be available for Windows 10 Mobile .

However the problem is one of search . Win 10 users cannot find my app either by name or by keyword . It works fine on Windows 8 . As for sharing a link that can only go so far . Ultimately I need my app to be searchable from the store . Comment : Yes but that s a different problem from what Leonardo asked and a very different statement from what you answered . Your app having search problems doesn t generalize to all Windows 8.x apps not being offered . That your app is a Windows 8 app may not be related to your problem at all the search heuristic is a black-box to me too . It is easily demonstrated that some Windows 8 apps can be found by search so it is definitely wrong to say that Windows 10 will not see any Windows 8.x apps .", "Question : I m developing a Windows store app and need to display files in user computer like in file explorer .

I think this might be related but I m not certain : fatal-error LNK1104 : cannot open file bcrypt.lib when building for Surface RT tablet http : stackoverflow.com q 36930563 . About all I know is this stuff does not appear to be well tested by Microsoft because there are too many damn problems trying to use it . .. . Answer : The main issue is that BCRYPT is supported for the Universal Windows Platform apps aka Windows 10 Store apps but was not supported for Windows 8.x Store apps . VS 2013 toolset always uses the Windows 8.1 SDK so you were building a Windows 8.1 Store app . When you tried VS 2012 you were using the Windows 8.0 SDK so you were building a Windows 8.0 Store apps . Again neither of this support BCRYPT . If you build with VS 2015 and have the Windows 10 SDK installed then your code builds fine . Note that D MBCS is not an option for Windows Store apps . All Windows Store apps should be built for Unicode DUNICODE D UNICODE and not ANSI Multibyte as you were trying to do . Also be sure to link with windowsapp.lib to make sure you pick up the correct DLLs when you link . You can easily confirm that all the errors you are seeing happen in VS 2012 2013 if you do not have include bcrypt.h in the file at all . The DWINAPI FAMILY WINAPI FAMILY APP ensures that all unsupported APIs are undefined so with Windows 8.x Store that header was basically an empty file . Comment : Thanks Chuck . It appears all of Microsoft s documents are broken .

Comment : They are all say Windows Store apps because these APIs are supported for Windows 10 . I agree it s not helpful to you that it fails to mention UWP or Windows 10 but at this point MSDN is only telling you about UWP not Windows 8.x Store . Comment : Thanks again Chuck . Would you mind taking a look at Preprocessor definitions for Universal Windows Platform http : stackoverflow.com q 36072350 . These questions are holding up the port of a few C C++ libraries I work with OpenSSL Crypto++ Cryptlib and Botan . Comment : Thanks again Chuck . Why does Microsoft state the API is available in NIST documents http : csrc.nist.gov groups STM cmvp documents 140-1 140sp 140sp1893.pdf The documents on file with NIST are legally binding unlike broken MSDN documentation . Here are the platforms they claim to provide the API : Microsoft Windows 8 Microsoft Windows Server 2012 Microsoft Windows RT Microsoft Surface Windows RT Microsoft Surface Windows 8 Pro Microsoft Windows Phone 8 Microsoft Windows Storage Server 2012 . Comment : All those platforms support the BCrypt APIs but they aren t available to Windows Store apps aka Metro style apps in Windows 8.x directly . Instead you can use the Windows Runtime class HashAlgorithmProvider https : msdn.microsoft.com en-us library windows.security.cryptography.core.hashalgorithmprovider.aspx . There is also a limited form of Win32 development for ARM devices for OEMs . That said I m not an expert in government compliance so you should contact Microsoft directly .

After a thorough investigation we came up with the understanding that you can publish java running apps as desktop apps only . You will need to sign up as a company in order to do so .

How much do they share from development point of view . If I spent time learning how to build Windows Store apps can this knowledge be transferred to UWP development .. . Answer : The Universal Windows Platform uses the same basis of technology that was developed for the Windows 8 Store apps . This includes AppX packaging with manifests the App Container security context CoreWindow presentation model same appmodels XAML XAML+DirectX DirectX etc . The difference is that UWP apps can run as is on a Windows 10 PC the Xbox One and Windows 10 Mobile . The main differences in the development model are that UWP supports more APIs . There are some APIs that have changed particularly from Windows phone 8.x but if you have written a Windows 8 Store app moving it to Windows 10 is mostly a recompile . You use the VS 2015 toolset rather than the VS 2012 or VS 2013 toolset . Unless you have some compelling need to support Windows 8 Store I d suggest just going with UWP . There s less code churn for existing codebases as a number of Win32 APIs that were not supported for Windows 8 Store apps are supported for UWP .

Please make sure to accept one of the answers or add your own so someone might benefit from this question and answers in the future . .. . Answer : Windows systems aren t locked in the same way as Windows Phones are . You will need a free developer license to run development test packages on the system but don t need to use an external tool to generate it . You can install a developer license with PowerShell by using the Show-WindowsDeveloperLicenseRegistration cmdlet . If you create a package for testing in Visual Studio then the Add-AppDevPackage.ps1 script will request the developer license if the system doesn t already have one .

Answer : Is there a way to make the DataTransferItem : : getAsFile method asynchronous No . It s specified http : www.w3.org TR html editing.html dom-datatransferitem-getasfile as synchronous . However there is absolutely no reason to make this asynchronous - a reference to the File is quickly constructed and does not incorporate any data shoveling . Just as input.files does synchronously get you references to not-yet-read-in files .

But when I tried to find documentation for it in a Javascript reference http : www.w3schools.com jsref obj window.asp clipboardData was nowhere to be found . Why Isn t window.clipboardData not part of Javascript or DOM .. . Answer : I believe only IE lets you access the clipboard . Older versions of other browsers used to but this has been switched off by default as a security measure . Users can explicitly turn it on via settings options preferences but this is obviously not ideal in most situations . The workaround is to use a flash object on the page . Since Flash 10 added more security layers user interaction is also required now with the flash object e.g . a click rather than say onload event .

When dragging and dropping a file onto a page you can get the file via event.dataTransfer.files when going through all the drag drop related events . Each file object then has a name attribute . When pasting a file onto a page you get the item via event.clipboardData.items which isn t quite an array or an normal object but I digress in the onpaste event . The item object then has a getAsFile method but this returns a Blob not a File so the name attribute is missing . What I m trying to do .. . .. . I would like to get to the filename so I can send it along to store as metadata with the image when I upload the image later . Is Chrome just buggy .. . .. . You would think that they would just reuse event.dataTransfer for this purpose but that s undefined .

All this is true at least in Chrome . Let s just say I only care about Chrome and maybe the latest versions of Safari and Firefox for now .

Answer : Chrome is the only browser that fully implements the Clipboard API . And as you have noticed the pasted item is made available as a Blob . It s not 100 clear if this is an error in the implementation of the Clipboard API in Chrome . The spec suggests that it may be but this has been in-place for some time in Chrome so you ll need to work around it . Another thought here is that there is no file name since there is no file just clipboard data . If you want to name pasted items you ll need to solicit input from the user . Comment : Thanks . I ended up filing a bug report because it appears to be wrong according to the specs : code.google.com p chromium issues detail id 361145 https : code.google.com p chromium issues detail id 361145 Comment : Apart from that the specs appear state that clipboardData should just be a dataTransfer object so to me it would make sense that the files attribute shouldn t have length 0 . It is all in the specs and if you look at the objects in Chrome they have the right types and attributes talking about event attributes not getAsFile s return-type they just aren t filled in . Comment : I think the chances of this being fixed are close to zero . In fact there s a better chance that the clipboard API will be dropped from the spec entirely since it has not been adopted by any browser other than Chrome . This is all just speculation on my part though so take with a grain of salt . Comment : Yeah yeah but what else can one do :", "Question : I need to store data copied from an app into another app s memory than letting Android store it in global clipboard . Is it possible to copy the data into a separate memory than the global clipboard . Any help would be appreciated . Thanks Nibs .. . Answer : You can use the ClipBoardManager http : developer.android.com reference android text ClipboardManager.html class to get clipboard data and save it to a file perhaps which the other app can access . See Copy and Paste http : developer.android.com guide topics text copy-paste.html for an example . Comment : yes @umair its obvious that i would be using ClipboardManager but how would i avoid lettting it store in the global clipboard and how would i be saving it in another apps memory Comment : If you save the data copied from the clipboard with a timestamp you can make the other app open the file and see if the timestamp is different to the one it previously has saved . If it is different you can perform the action you want with the new data . Do you also want to explicitly stop the data being posted to global clipboard Comment : The timestamp in my case wont work . I do not see as a solution to my problem . Yes i need to explicitly stop data from being posted on global clipboard . Comment : Another idea : implement a background listener in the second app that listens for a clip with a particular tag you set in the first app using OnPrimaryClipChangeListener getPrimaryClipDescription and getPrimaryClip . When it s a match you can save it to a local variable in the second app . Users don t copy often enough for this small check to be heavy . Maybe you can reset the clipboard to a blank string using OnPrimaryClipChangedListener in the first app get its description and post another item to the clipboard with the same description but empty content .", "Question : I m a complete beginner at C++ but I ve managed to modify other people s code and finally put together a program that writes the Windows clipboard to a text file with the text encoded in the codepage specified as a command-line parameter for the program for example MyProg.exe 437 will write the text in codepage 437 . If no codepage is specified the program writes a text file in the standard Windows codepage 1252 . The trouble is that the program crashes if the clipboard contains for example a shortcut or file not text . Can someone tell me how I can exit gracefully if there is no CF TEXT data in the clipboard Or have I completely misunderstood the problem I ve searched for an answer with no success . Here is my VC2010 code which I don t entirely understand but it seems to work when the clipboard contains CF TEXT it doesn t work with CF UNICODETEXT by the way - the output is simply a few bytes . : .. . .. . I ll be grateful for any suggestions on how to fix this last problem . .. . Answer : Before you get data from the clipboard using the GetClipboardData function you have to check that the clipboard contains data in the format that you expect . This can be done using the IsClipboardFormatAvailable https : msdn.microsoft.com en-us library windows desktop ms649047 v vs.85 .aspx function as follows : .. . .. . Then you have to open the clipboard and obtain a handle to the clipboard buffer as follows assuming the clipboard contains ANSI string : .. . .. . Then you have to obtain exclusive access to the data using the GlobalLock https : msdn.microsoft.com en-us library windows desktop aa366584 v vs.85 .aspx function . Only on success you can safely access the data .. . .. . The return-type of GlobalLock is a void pointer . So depending on the data format which you have already determined using IsClipboardFormatAvailable you have to cast it to the corresponding type . Windows data types are documented here https : msdn.microsoft.com en-us library windows desktop aa383751 28v vs.85 29.aspx . Comment : IsClipboardFormatAvailable is useful for setting the UI for example determining whether a drop-down menu should offer a Paste option but using it to ensure that GetClipboardData will succeed is sketchy . Unless you ve already opened the clipboard the data can change between the time you check and the time you actually call GetClipboardData . The real fix which this answer shows without comment is to check the return-value from GetClipboardData before trying to dereference it . Comment : @AdrianMcCarthy Yes . That s why OpenClipboard has to be called before GetClipboardData to prevent other programs from modifying the clipboard until CloseClipboard is called . In this case GetClipboardData will only fail if the format of the data in the clipboard is different from or cannot be implicitly converted to the specified format . Comment : I would like to add also that if the handle returned from GetClipboardData is itself a pointer to the first byte of the data such as when the data format is CF BITMAP then GlobalLock should not be called . That pointer however should be checked against NULL . Comment : If you call 1 IsClipboardFormatAvailable 2 OpenClipboard and 3 GetClipboardData as your answer suggests then there s a race-condition between 1 and 2 which is the point I was trying to make . Comment : If you read my original comment carefully you ll find that s exactly what I said .", "Question : I m using the Quicksilver clipboard history plugin to record the last 15 items . The problem is i sometimes need to copy-paste passwords or other sensitive data from 1Password for example and i was wondering if there was a way to not log this type of data .

Answer : Quicksilver and or Alfred would need to be aware of where those clips came from i.e . from 1Password etc in order to exclude them . 1Password itself has an option to remove the clipboard data after a certain period of time 90 seconds by default I believe .

Comment : yes U right i Resolved this Question by taking out that jar from class path u can put it as ans i will accept : .. . Answer : The Windows version of SWT is named swt-win32 even on 64-bit platforms . So you have to change the classpath to point to the correct name for SWT on the platform you re using .

Comment : Oh blah the multiplatform thing is only for WebStart applications https : www.eclipse.org swt jws .", "Question : Nowadays I am working on a java swing application using DJ NativeSwing as my embed browser to do something automatic work . The scenario of my application is that a user click start button and the embed browser auto click some position of the current page and then redirect to another one and then execute some other operations like click or something other . Now here is my solution . First I will define a webbrowser class extends JWebBrowser and webbrowser listener class implements WebBrowserListener which represents a webbrowser and contains loadingProgressChanged windowOpening and so on separately . Second I define a thread class to do some logic computing and execute my browser operations as mentioned above by webbrowser.executeJavascript . At last I add mouseListener for start and stop button to start or stop the task . When I open my application the JFrame add the browser and its listener class . I click the start button the browser works and will click the target position as I expected and then the page will redirect to another one . As we all konw js code can t be executed until the page was loaded completely . So I set a global flag to check whether the page has loaded completely or not in loadingProgressChanged code : if e.getWebBrowser .getLoadingProgress 100 globalflag true within webbrowser listener class . And in the thread class I use code while globalflag false Thread.sleep 500 after first click to detect if the current page was loaded completely . However when browser first click the target position and the page redirects successfully I find that the current page has changed but blocked . After some debugging I find it . In my thread class browser will execute js code by webbrowser.executeJavascript document.getElementById target .click to click the target position and then java code while globalflag false Thread.sleep 500 to detect if the current page was loaded completely and then execute some other java code . I find that the globalflag will never change and the current page s loadingProgressChanged listener will never work because the java code while globalflag false . Because after I remove all java code after the first webbrowser.executeJavascript document.getElementById target .click the current page s loadingProgressChanged listener works and the page was not blocked . With the DJ NativeSwing demo I could execute my js in the loadingProgressChanged . However I want to do a series of operations with my browser and also want to stop the task whenever need . So I prefer to my solution for my demand rather than the provided one by demo . So I wonder that after webbrowser.executeJavascript the DJ NativeSwing thread will wait my thread And in my software architecture does anyone could have any suggestions Thanks a lot . Any suggestion is appreciated PS.my application works fine with jdic-0.9.5 but it supports IE7 only . I paste my code here to demonstrate my problem : After I click the start button in JFrame I will new a thread as follow .. . .. . .. . public class MyVisit implements Runnable .. . private void doClick1 .. . webbrowser.executeJavascript document.getElementById n .value test .. . webbrowser.executeJavascript document.getElementById f .submit .. . .. . public void run .. . globalFlag false .. . webbrowser.executeJavascript document.getElementById t .click .. . while globalFlag .. . Thread.sleep 500 .. . .. . this.doClick1 .. . .. . .. . .. . .. . public class MyListener implements WebBrowserListener .. . .. . public void loadingProgressChanged WebBrowserEvent e .. . if e.getWebBrowser .getLoadingProgress 100 .. . globalFlag true .. . .. . .. . .. . Answer : DJ Native Swing enforces the Swing approach to threading : manipulate the components in the AWT Event Dispatch thread a.k.a . UI thread . But also do not block that thread because listeners are triggered in that thread too . So you should not have a while-loop in the UI thread but should instead spawn a new thread . I hope your global variable is volatile or AtomicBoolean or all accesses to it protected by synchronized block otherwise you might have interesting threading side effects . Comment : Christopher Thank you very much.But I really don t understant what you mean.And I paste my code in my question.When I click the start button in my application main page I will execute the following code : new Timer .schedule new TimerTask public void run new Thread MyVisit .start would you give me some more detail suggestions Nowadays I am really stuck by this problem after I replaceed JDIC with DJ NativeSwing and look forward to your response anxiously.Thanks again", "Question : I am using DJ Native Web Browser .

Why should it have the value 193m if you didn t set that before and then you probably know it And if it has this value yes you are right you would have to parse the output of list-jvm-options to find it out .

At the moment I am using asadmin for this and it works fine but this option requires me to have Glassfish installed on the build-server as well - which I would like to avoid as I do not need it there . The build-server is really only running the builds and the deployment so I would like to keep the server as clean as possible . I can t find any download that installs only the asadmin tools and also my attempt to manually copy over only the required files failed as there are some dependencies to certain .jars that I don t know of so it always fails unless I copy the whole glassfish installation folder to the build-server . So my question is : Does anybody know how to install only the asadmin tools without installing the whole Glassfish server Alternatively I would also be happy to use any other command-line tools as long as they allow me to deploy to a remote Glassfish instance using secure communication . .. . Answer : After doing a bit more research I gave up on trying to install asadmin without the full Glassfish installation and instead used Glassfish s REST admin interface . I now made it work using CURL in a simple batch-file : .. . .. . The REST API is fairly straight forward once you know what you need to do but just in case somebody else needs this here a couple of important points : .. . .. . --insecure is required by CURL to allow self-signed and untrusted SSL certificates .. . The header attributes for Accept and X-Requested-By must be set otherwise Glassfish doesn t process the request and simply returns a blank document as an ansower . No idea why but setting these parameters made it work . The content of the war file is passed as the id parameter on the POST .. . The URL needs to be exactly as shown in the snipped above i.e . do not replace domain with your domain-name or application with your application name . This is the actual REST interface endpoint . There is no need to specify the domain application name anywhere . Comment : what is the file set that you are physically deploying can t you just drop the war file on the server and done deal is there more to it Comment : In my situation the build-server does not have access to any shared drive on the application server . In order to allow a simple file drop with autodeploy we would have to share the respective autodeploy folder but this is not an option here . The use of CURL allows us to do this via HTTPS .", "Question : Due to project limitations I need to configure my GlassFish installation using asadmin within a shell script linux .

Answer : asadmin deploy moves your deployable code to the autodeploy directory making glassfish aware of its existence to deploy . I believe copying a simple library out there won t net any effect without proper deployment descriptors . In any event I don t think the asadmin deploy would have access to your domain lib or server lib directory but rather only your application directory structure itself .

The DAS and two instances are setup as Window 7 services that use a logon account that has administrator privileges . Upon starting the machine the service starts and the DAS is up along with the instances . From Windows Task Manager this appears as two java.exe processes per service for a total of 6 java.exe s . The problem is that if I use the asadmin restart-domain command two new java.exe processes spawn and the two old ones do not die . The application that is deployed works fine but with enough restarts using asadmin the memory starts to fill up from zombie java.exe s . Oddly enough running asadmin stop-domain will stop the two DAS java.exe processes but then running asadmin start-domain starts Glassfish as a non-service . The only way to start the DAS back as a service is to run sc start domain1 or restart the machine . Also the only way to stop the DAS java.exe processes is with asadmin stopping the service using sc stop domain1 stalls and does not work . It is also odd that each service DAS instance 1 and 2 starts two java.exe s vs starting only one each when running as a non-service .

Any advice would be much appeciated .. . Answer : I am using this on yosemite and am not having any problems . I would suggest that you go to the aquamacs.org site go into the developers area . There was a problem unrelated to what you are showing with yosemite and the developer there was very helpful in fixing it . I would email him he probably can from your info tell you what is going on . Before doing that try the development version that is on that page just in case that fixes it for you . That is the one I ended up using and I don t know if they have forced it back into the main download yet . Also they have all the old email listing of problems that you may want to troll through . I use it for latex and find it is excellent . Particularly when teamed with skim .

Answer : Hi there and season s greetings As a total non-programmer I need help on how to prepare my Macbook Air OS X 10.10.5 for installation of Aquamacs . I have been running Spacemacs which uses its own .spacemacs initialization file but I am concerned that my lack of knowledge of what where other Emacs files folders exist on my machine could mean trouble when I install Aquamacs . Does anyone have any suggestions for me Many thanks Chris . Comment : Unless you cannot live without the OSX native spellchecker you should do yourself a favor and forget about using Aquamacs -- there is really no other reason to use Aquamacs in my opinion . Use this instead : emacsformacosx.com http : emacsformacosx.com Other people will tell you to try homebrew or macports but only the one I just mentioned will put everything in the Emacs.app bundle . Both homebrew and macports will install the guts in other areas of the computer which just makes life a pain in the neck -- especially if you want to synchronize everything across multiple computers and backing up as well Comment : Hi lawlist thanks for your quick reply . I assume that because emacsformacosx puts everything in the Emacs.app bundle there is no need to worry about conflicts with Spacemacs - which I can keep and run also Comment : I installed emacsformacosx but running the app gives the same Spacemacs Emacs as I was already running . I m sorry for my ignorance but I guess there must be an initialization file somewhere that points Emacs to the .spacemacs file . I do like Evil anyway . Comment : Sticking with spacemacs for now . Thanks . Comment : Spacemacs is just a bunch of elisp user customizations and additional third-party libraries designed for the generic build of Emacs -- i.e . it is nothing special because it doesn t really alter the Emacs build . I seriously doubt that anyone spent significant time making sure that Spacemacs plays nice with Aquamacs but I could be wrong Aquamacs is a bunch of C-Source modifications and customizations by the developer and on top of that a whole bunch of additional elisp modifications and customizations by the developer plus some additional third-party libraries .", "Question : I am trying to write R scripts in aquamacs but whenever I type an underscore as part of a variable name the editor automatically changes this to - . One answer is to just stop using the underscore but I m working with some pre-existing R code all of which is rife with underscores in the variable names . How do I stop aquamacs from doing this I m using aquamacs 3.0 and OS X 10.7.5 . Thanks .. . Answer : Use M-x ess-toggle-underscore to unset this ESS default : .. . .. . You can set unset this in your .emacs as well . That being said underscores are evil in variable names . Don t believe a word Hadley says in the matter -- it is camelCase all the way .

I ve tried running some simple lines-of-code with Feed Region ex : .. . .. . but no luck just the code error . Thanks in advance . I didn t know which section to post this in as after looking at all the other posts it looks like a general error not Aquamacs specific .. . Answer : You are getting this error because you are using Mozart 2 which is only supported on OS 10.8 10.9 . For 10.7 use Mozart 1.4 . Now if you have installed Aquamacs3 Mozart will not be able to find Aquamacs . That s because the Aquamacs has changed the directory names a bit . To solve that problem open up Terminal and type in the following commands : .. . .. . ln -s Applications Aquamacs.app Applications Aquamacs Emacs.app ln -s Applications Aquamacs.app Contents MacOS Aquamacs Applications Aquamacs.app Contents MacOS Aquamacs Emacs .. . .. . This of course assumes that you have put Aquamacs in applications . If not change directories in the commands above accordingly . Hope this helps . Comment : Hi thanks . In fact I tried all that a while ago and it didn t help . In the end I just downgraded to the 1.4.0 version....which works like a treat . Thanks for the suggestion anyhow .", "Question : I happen to have two emacs on my Mac because of clojure setup http : stackoverflow.com questions 3261714 emacs-cocoa-emacs-vs-aquamacs-for-running-clojure-on-mac-os-x . The problem is that Cocoa emacs and Aquamacs uses the same .emacs.d but the ELPA of Cocoa emacs and that of Aquamacs are not compatible so that some files are overwritten and not usable for both of them . Is there any way to tell Aquamacs not to use .emacs.d for ELPA I mean can I change the default ELPA directory other than .emacs.d I use Aquamacs Starter Kt http : github.com walter aquamacs-emacs-starter-kit but it seems that the .emacs directory is used in init.el . .. . Answer : I am not familiar with ELPA but if aquamacs and carbon emacs are using different copies of package.el you could try changing the definition of package-user-dir in one of them . In general I have found that using two different emacses on one machine is a recipe for baldness .", "Question : I m on GNU Emacs in OSX Mavericks and I m trying to make my background transparent but not the text .

Again I want the window 100 transparent and the foreground text 100 opaque and it should work in Emacs full-screen mode . Comment : An alternative is if you re willing using emacs from the Terminal you can create a new shell profile under preferences and set opacity to 0 and blur to 0 . .. . Answer : The following are a few screen-shots and the different .emacs settings that were used .

Example http : www.lawlist.com images semi transparent b.png .. . .. . .. . .. . EDIT February 24 2014 : The following is a link-to a related thread where the lead developer of Aquamacs i.e . David Reitter has suggested modifying nsterm.m as a potential solution : http : comments.gmane.org gmane.emacs.aquamacs.devel 836 -- At a minimum the changes would be to ns clear frame and ns clear frame area . Instead of filling the background with the background-color you could try setting the alpha component of the NSColor object so that it is transparent copying in the actual background of the window . So then you d have the frame background transparent . That doesn t take care of the frame UI elements . . . In other words the potential solution would likely entail modifying the source code prior to building a custom version of Emacs . Comment : Aquamacs has a million things that have been customized by the developer s beyond that of the vanilla build . I m sure you can track down the setting that is causing your issues but it may be time consuming . My advice would be to forget about Aquamacs and use emacsformacosx.com http : emacsformacosx.com and eventually you can build your own . I initially gravitated to Aquamacs because of the native OSX spell check and the right-click context menu . In the end I opted for Aspell and a vanilla Emacs build and I created my own right-click context menu . Comment : If you use a .emacs file containing only the two lines-of-code in your question and the code in my answer then it works with a current version of Emacs trunk built --with-ns on OSX Snow Leopard 10.6.8 . So my best guess is that you have something else in your configuration-files that is conflicting . Try it with just the code in your question and my answer with nothing else in the init file and see if it works . Comment : The builds from that website are made with the ns option so you just need to decide upon the last stable release or a developer build with a sneak preview of what is to come . The latest developer snapshot build will have many good bug fixes but may have new issues not yet known . The latest build of Emacs Trunk does have full-screen . Comment : Your picture certainly does help me understand what you are seeking -- thank you . Comment : Emacs and Aquamacs both use nsterm.m so the proposed modification could be to either version . However the code is written in C and is thus far beyond my present level of minimal coding knowledge . If you download the source code for either Emacs or Aquamacs and take a peek inside nsterm.m you ll see what I mean . Aquamacs makes some additional custom changes to nsterm.m e.g . for the native OSX spell checker : github.com davidswelt aquamacs-emacs blob aquamacs24 src https : github.com davidswelt aquamacs-emacs blob aquamacs24 src nsterm.m", "Question : I ve been trying for a bit to disable the tabbar mode in aquamacs : when I open a new file from one buffer I d like the file to open in the current buffer instead of opening the file in a new tab .

Comment : How much is the difference is it reproducible and how does it change if you repeat a 100 times after each other This would interesting to add to your question . Comment : the difference is in terms of printing the output not the computation . I guess my point is that the cran gui seems more responsive aquamacs seems a bit lagged Comment : Printing 100000 numbers to the screen is always going to be slow and can differ heavily depending on the means how they are put on the screen .

Comment : Apparently the SNMP extension agents that you refer to can only be developed in managed code see here : stackoverflow.com questions 5057785 http : stackoverflow.com questions 5057785 looking-for-an-net-snmp-extension-agent Comment : @TonPlooij : I guess you meant unmanaged code . I am trying to understand why can it not be done in managed code as both native C++ and C++ cli have same target CPU and same dll exports . Why is the snmp service not picking up c++-cli dll", "Question : I was using php-5.4 fine with its php snmp.dll enabled but as soon as I upgraded to php 5.6.7 I cannot use php snmp.dll anymore . I just upgraded to php 5.6.10 hoping that snmp problem would be fixed but its not . If I comment out that line in php.ini php does not crash and my apache 2.4 webserver starts and runs fine . Does anyone have this issue with above mentioned php versions Comment : version of windows Comment : windows-8 or 8.1 .. . Answer : I actually just found a comment in here http : put.hk article news.php.net php.bugs 187845 Bug-68001-Fbk-Nab-php-crashes-with-enabled-php-snmp-dll.html that helped me solve the issue . Basically in c : usr snmp persist mib indexes directory I found two files named 0 and 1 . If you remove them SNMP extension works fine .", "Question : I m using SNMP agent and server but executing snmp agent snmpwalk or snmpget on centos ubuntu system occurs that failure Bad operator DEFINITIONS : Comment : Please add full command error message Comment : pastebin.com SPQDfBWt http : pastebin.com SPQDfBWt Comment : better to edit your question to include the extra info rather than to add it as a comment and or link . .. .

So this line will ask each Pod s aggregate target pod targets that aggregate pods for a specific app target s which user project it belongs-to and then we remove duplicates on that list of user projects .

Looking through the spec repo I only find one public spec that seems to have done this as a xcodeproj script in the past but no longer does : https : github.com CocoaPods Specs blob e187366577d112519af7c75d5eb35c583759103e Specs DevMateKit 1.1 DevMateKit.podspec.json .. . .. . Is there a supported way to do this Is this the recommended way to proceed or was it abandoned for good reason", "Question : I want to fix Cocoapods bug when it adds Embed Pods Frameworks build phase for Extension targets . These phases are not needed there . https : github.com CocoaPods CocoaPods issues 4203 .. . .. . I wrote script to remove it .. . .. . I can run this script after pod install manually but I want to add it to Podfile somehow . It doesn t work in post install hook .. . .. . because UserProjectIntegrator.integrate is called after post install and it overrides my changes . Is there any way to integrate this script in Podfile Comment : It will be a nice idea to add this to the podfile . Any success on this Comment : @the.evangelist no : and no news from github issue . I m running ruby script manually after pod install . .. . Answer : The short answer is No . The long answer : .. . From the output of pod install --verbose the build phase Embed Pods Frameworks is added in the Integrating client project which runs after the post install step in the Podfile . This is why you should execute this script separately after the pod install finished running .", "Question : I m writing a post install script in my Podfile in order to enable gathering of code-coverage reports from my framework when I run the unit tests in the example project . Here s what I ve got : .. . .. . When I print out the scheme I can confirm that code-coverage gathering is enabled and when I check the modification date of the file it is updated to the current time although that is easily explained by the fact that I m running pod install . The code-coverage option is not being written back to the BonMot.xcscheme file . Why not .. . Answer : Looks like post install is too early to work with schemes . CocoaPods installer calls write pod project method right after run podfile post install hooks during Generating Pods project step https : github.com CocoaPods CocoaPods blob master lib cocoapods installer.rb L166 and there is recreate user schemes call https : github.com CocoaPods CocoaPods blob master lib cocoapods installer.rb L693 inside .

What am i doing wrong Thanks for your help Muff Comment : @michaPau : Good find . .. . Answer : JavaScript date time numbers are milliseconds since The Epoch not seconds since The Epoch like old-style Unix Epoch values . If you have a value in seconds multiply by 1000 : Comment : Thanks - I just wonder why this is not uniformed so that the unix-timestamp is generally served in milliseconds . Comment : @Raggamuffin : History . For years time values were measured in seconds since The Epoch . This started in the 1970s . Then we felt the need for more precision and more modern systems started using milliseconds since The Epoch . Now there are even more modern systems using even more precise systems such as Microsoft s ticks since January 1 0001 at 00 : 00 : 00.000 in the Gregorian calendar a tick being 100 nanoseconds . Early Unix hackers wouldn t have dreamed of using the amount of storage for a time value that C uses for DateTime but things have moved on a bit in the last 45 years .", "Question : If all I have is the unix-timestamp and I am not able to use any functions to format it such as day of the week or date is there any known pattern by looking at the timestamp to deduce what day of the week it is for example perhaps all timestamps that are divisible by 150 are Mondays Comment : don t forget about leap years Comment : @DanielA.White : Actually for this particular problem do forget about leap years . The unix-timestamp is a count of seconds and each week is 2073600 seconds long . The day-of-week cycle is independent of months and years . Now if you want to know the day of the week in local time you need to account for DST transitions which you can t reasonably handle without library functions . Comment : Is there some reason you re not able to use library functions Also do you want the day of the week in UTC or in local time The latter is going to be a lot more difficult . .. . Answer : The Unix Epoch Jan 1 1970 00 : 00 http : currentmillis.com 0 was on a Thursday . Specifically it marked the beginning of a Thursday . The first Monday after the Unix Epoch http : currentmillis.com 345600000 begins on Jan 5 1970 00 : 00 . This is a UNIX timestamp of 96 hours . The second Monday after the Unix Epoch http : currentmillis.com 950400000 begins on Jan 12 1970 00 : 00 . This is a UNIX timestamp of 264 hours . Let s assume X is your Unix timestamp in hours . The formula X - 96 264 - 96 24 will return a zero-based weekday index where 0 is Monday and 6 is Sunday . The formula looks like this : .. . .. . X - 96 168 24 if X is your timestamp in hours .. . X - 345600 604800 86400 if X is your timestamp in seconds .. . X - 345600000 604800000 86400000 if X is your timestamp in milliseconds .. . .. . If i experiment with exactly this moment defined by a Unix timestamp of 1466710873523 ms i would get 1466710873523 - 345600000 604800000 86400000 which is 3.8 meaning it s Thursday almost Friday though : . Note though that it s Thursday UTC - in certain timezones it might be different so for local time you would need to take timezone offset into account .", "Question : How do I get a uint unix-timestamp in C++ I ve googled a bit and it seems that most methods are looking for more convoluted ways to represent time .

Comment : How do I get a uint unix-timestamp in C++ - given - as you ve said - you can call gmtime later to get a readable representation of whatever that timestamp encodes what functionality requested in the question isn t satisfied by time regardless of the reference date or suitability for interval calculations Comment : To get a UNIX timestamp on a non-UNIX system you have to know the difference in seconds between the local epoch and 1970-01-01T00 : 00Z . There s just no method which does that . Comment : For some reason I got the impression the question was for code on a UNIX or Linux etc machine but now I see where you re coming from .

One camp claims the answer is 315964800 the other claims it is 315964819 . I always thought it was 315964800 but now am not so sure . I just found my software baseline has been using 315964819 for the last eight years . I have a hard time understanding how it could have been 19 seconds off and no one noticed it when we integrated our embedded devices with other devices . I think that whoever put 315964819 in the code baseline must have mistakenly used a TAI offset 19 seconds . From what I understand Unix time does not include leap seconds which would indicate to me that 315964800 is the number of ticks between the two epochs . Then I think about how Unix time handles the leap-second . It simply repeats the tick count when there is a leap-second inserted and there were 19 leap seconds inserted between 1970 and 1980.. . I start to wonder if the repeated ticks matter . I do not think so but someone in this code s history thought so and it seemed to work... .

The right zoneinfo files assert that the system clock value of time t represent the actual number of seconds in the internationally approved broadcast time scale since 1970-01-01 . As a result the value of time t which is expected by the right zoneinfo files is greater than the value of time t specified by POSIX .

I need Thread safety .. . 2 . 2010-01-01 must result in 1262304000 .. . 3 . 0001-01-01 must result in -62135596800 .. . 4 . 2999-12-31 must result in 32503593600 .. . .. . EDIT 1 .. . .. . I also tried the following Java 6 code : .. . .. . This works with 2010-01-01 and 2999-12-31 but not with 0001-01-01 expected : -62135596800 actual : -62135769600 - guess the missing setGregorianChange is what troubles here . EDIT 2 .. . .. . The code is running in a JsonSerializer . I have an application presenting those UNIX timestamps inside a JSON . The consuming side expects the timestamps as GMT Timestamps and will create a date by this timestamps hardcoding the timezone to GMT but use it later as it where local timezone . To make the problem more clear I ll present an example . Date on my side : 2010-01-01 UTC+100 .. . milliSeconds : 1262300400000 .. . seconds : 1262300400 .. . .. . the consumer now takes this seconds and forms a date out of it : .. . .. . Thu 31 Dec 2009 23 : 00 : 00 GMT .. . .. . Of course - this is 100 correct but the consumer does use this date as-if it where a local timezone date.. . The seconds I expect to be transfered are 1262300400 + 3600 my TZ Offset for this example . EDIT 3 .. . .. . I got the GregorianCalendar -thing down to a 4liner - but even this is much slower than the Java 8 thing . The problem is the creation of a new GregorianCalendar Object each time the code is executed . But this is a must-do since Calendar not threadsafe . So a fast solution must somehow work without any object-instantiation . The example below is mostly like EDIT 1 and is even faster than the Java 8 code . It just does not work correctly with dates before the Julian - Gregorian switch 15-Oct-1582 . Unfortunally it works a with a deprecated method and b does not work correctly with dates before 1582 : . Using a static TimeZone.getDefault .getRawOffset to solve a is not an option as the TimeZone may change summer- vs . wintertime on each date . Comment : I m gonna be that guy and ask if you have tried joda time joda.org joda-time http : www.joda.org joda-time Comment : Why are you getting a Calendar instance and the proceed to create another GregorianCalendar completely ignoring the calendar obtained before . Start by removing the dead-code Comment : @DamienO Reilly - I want a solution without any dependencies . Comment : @Olli If you read-the-docs A java.sql.Date is a wrapper around the time stamp . getTime Returns the number of milliseconds since January 1 1970 00 : 00 : 00 GMT represented by this Date object . You might change he timezone for representation but it is still the same timestamp . Comment : @Durandal - I could create a GregorianCalendar call setTime do the y m d extraction as I do above and then continue with clear and so on . This will indeed save me the first Calendar.getInstance but does not change the execution-time . 127 980 executions Original Java6 code : 35 402ms One-Calendar-Instance-Java6 code : 35 794ms Java8 code : 19 086ms .. . Answer : Comment : the question was : GMT Comment : The number of seconds between Epoch and some point in time date doesn t depend on timezones . Comment : Epoch has a time zone and date has a time zone too.. . - I assume that the issue is that he has to ensure that they have the same GMT . Comment : @Roman - a regulary created java.sql.Date object will represent the ms since epoch in your local timezone when you just call getTime you ll exactly get that . Comment : @Olli the javadocs exactly contradict what you are saying . The epoch is January 1 1970 00 : 00 : 00.000 GMT . So if you have a date in a different timezone it has the same number of milliseconds since the epoch . Are you saying your date has been created from an incorrect epoch" ] }	[ "yes-answer-long", "yes-answer-short" ]	unix	UNK_RELATION

I have seen usages of the var mail directory - with one file per user - which does not seem like it is intended for a large userbase . Wouldn t it also cause issues when two processes read-write from this at the same time I have also seen the Postfix main.cf file possibly contain mailbox transport lmtp : unix : var imap socket lmtp which looks like the LMTP protocol being used to communicate to the IMAP server using a unix-socket .

Comment : Typically it s stored in a database or the filesystem . For Unix systems this is typically home user mail or older var mail . For something like Exchange it ll be a proprietary database .

MTA must know valid virtual mailboxes .", "Question : A rails application in production should use smtp or sendmail to send mails Comment : smtp is a protocol not a program . .. . Answer : SMTP is the protocol that is used by nearly all Internet hosts to send mail . This protocol is spoken by sendmail . Sendmail determines where to send your message and how . Some mail programs most today will connect directly to a mail-server and speak SMTP to it . However the traditional method - and arguable the better method - is to let sendmail do it . There are two reasons for this : 1 nearly every program in UNIX that does what sendmail does is designed to be a drop-in replacement this includes Postfix http : www.postfix.org and Exim http : www.exim.org for instance and 2 sendmail or its replacement was designed to handle mail and nothing else - by using sendmail you don t have to design a SMTP client . The Mutt email-client for UNIX is one email-client that still refuses to talk SMTP directly to a mail-server a good technical description is on the wiki http : wiki.mutt.org MuttGuide Send . If you have a choice on UNIX anyway of talking SMTP directly or using sendmail use sendmail - especially on servers .

Port 587 : SMTP Message submission SMTP-MSA a service that accepts submission of email from email clients MUAs . Described in RFC 6409 . Port 465 : URL Rendesvous Directory for SSM sic entirely unrelated to email .. . .. . Historically port 465 was initially planned for the SMTPS encryption and authentication wrapper over SMTP but it was quickly deprecated within months and over 15 years ago in favor of STARTTLS over SMTP RFC 3207 . Despite that fact there are probably many servers that support the deprecated protocol wrapper primarily to support older clients that implemented SMTPS . Unless you need to support such older clients SMTPS and its use on port 465 should remain nothing more than an historical footnote . The hopelessly confusing and imprecise term SSL has often been used to indicate the SMTPS wrapper and TLS to indicate the STARTTLS protocol extension . For completeness : .. . .. .

The mail is sent to the exchange-server then the exchange groups the domains company.com and gmail.com it puts the mail into [email protected] mailbox . then the exchange sees that it needs to send into [email protected] so it will send it to the relay server . the relay server will get the SMTP request : .. . .. . from : [email protected] .. . .. . to : [email protected] [email protected] .. . .. . .. . .. . the question is - how does the smtp relay server knows not to send it to [email protected] - thus causing duplicate mails received also how does the gmail server knows not to try to send the mails it receives again because they only get smtp requests similar to a client that sends the mail .. . .. . thanks in advanced .. . Answer : The content of the mail is not parsed by either exchange or the relay for determining where the mail should go . Everyone in this context is talking SMTP with one another and specify recipients with the RCPT protocol message . So your mail client tells exchange two RCPT exchange decides one of them is remote then says one RCPT to the relay and so on and so forth . This document ftp : ftp.rfc-editor.org in-notes rfc5321.txt specifies the SMTP protocol where you may read about the RCPT verb . Comment : does it mean that the relay get [email protected] but the to field will contain both mails Comment : yes the mail relay or transport agent must not mess with the To message header . it is only allowed to add certain headers of it s own for accounting purposes as indicated by other commentaries in this question .", "Question : I keep getting this error when I try to send an e-mail in PHP : .. . .. . my php.ini looks like this : .. . .. .

Answer : It depends on how the MTA is programmed . The SMTP protocol allows the sender to send multiple RCPT TO commands to list all the recipients of a message and any reasonably-designed MTA will make use of this to consolodate them . For the multiple-domain case your mail client will use a single connection to upload the message to its submission server .

What exactly does an MTA do Everything after the SMTP protocol seems like dark magic to me . Let s say that I wanted to code a minimalistic MTA or MDA http : en.wikipedia.org wiki Mail delivery agent just for sending emails what would I need to learn do Edit : I don t actually plan on writing an MTA I just want to understand how it works internally . .. . Answer : Here ya go : http : en.wikipedia.org wiki Message transfer agent .. . .. . Quickly the MTA receives the raw message decides where it s ultimate destination is and then forwards the message on to that destination . A very simple MTA can be written the delivers only to local inboxes . The MTA is an easier part of the system to write because you can behave badly but still be functional so your interoperability with other systems is less of an issue that s where much of the complexities of email lie nowadays that and spam virus checking . The real contract of an MTA is simply that if you accept the message from the system sending it to you you accept responsibility to deliver that message . Thus when that socket closes with an acknowledgement of acceptance the delivering systems job is done and it s all in your hands . If you happen to do a crummy job mail is lost and it s your problem . But it s still fun to play around with . Comment : What I m trying to figure out is how it forwards the message to the destination.. . Surely there must be some kind of protocol involved no Comment : All depends on the destination no The MTA is what listens to the SMTP port on the server so it accepts the request from the client an email program or another mail-server . If the final destination for the message is simply a local inbox then the protocol can be as simple as appending the message to an mbox . If the final destination is somewhere else i.e . another mail-server then it s likely going to be using SMTP to xfer the message . Comment : I tried connecting to Google MX and SMTP servers directly on port 25 and 587 then I sent some data according to the SMTP protocol without authentication which should be the way my local MTA does and the message was not delivered . Using the MTA it does but why Comment : Works for me sorrry - connecting to gmail-smtp-in.l.google.com port 25 . I can HELO test and MAIL FROM : [email protected] and get a positive response . Comment : Ah right - yes I think the SSL SMTP on 587 is for sending email out not in . So that would need authentication yes . For SSL in I think you make a plain connection on port 25 then request an upgrade to TLS on the same connection with STARTTLS", "Question : Youtrack allow to send email through 3rd party SMTP server .

What the username and password below refer to How could I login to the server with user and password and then to the mailbox other user and other password Thank you to who will be able to help me . .. . Answer : To send email using SMTP authentication you only need to log in once with a username and password permitted to relay through that server . When an SMTP server is also the Mail Exchanger MX for a domain the username and password used for SMTP authentication are usually the same as those used to receive email using POP3 IMAP where the mailbox exists on a Mail Delivery Agent MDA http : en.wikipedia.org wiki Mail delivery agent .

Why have 2 instances of a SMTP server running on the same server if they both do the same thing What security feature does it provide besides giving me 2 things to troubleshoot as an administrator . This just seems like unnecessary complication that isn t needed unless the ISP blocks port 25 . Even then if the ISP is blocking port 25 to prevent spam it just means it will just take a little more time until port 587 is blocked too and we will have to use a different port altogether . Just seems like we are creating more work for ourselves rather then solving the problem and authenticating SMTP to begin with .. . Answer : I had a quick reading through the RFC and their thinking is to divide the SMTP world into two areas : transporting mails that s what SMTP was developed for and submitting mails . The authors argue that SMTP was not meant to be used by a mail client MUA Message User Agent but only by mail servers routing a mail to its destination . They think that if you divide the SMTP world in this way then you could write a SMTP server meant to be accessed only by MUAs that is then able to do things and make assumptions a normal forwarding SMTP server should may not make . A normal SMTP server has always been called an MTA Message Transfer Agent . The authors propose to name the new type of SMTP server MSA Message Submission Agent . It seems they think this would make implementing the two server types easier and maybe even more secure . The RFC explains what needs to be different in an MSA when compared to a MTA . For example the RFC mandates the use of authorization while the original SMTP protocol didn t have that SMTP AUTH was added later it seems by the very RFC 2476 however SMTP AUTH itself is the later specified in RFC 2554 which has been replaced by RFC 4954 . An MTA that needs to relay messages from various sources to various destinations cannot use authentication for every message how should another server authenticate to your server . But an MSA which is the starting point of your message can and must require authentication from its peer the mail client . And while an MTA must relay the message unaltered save for adding a Received header and MSA may sanitize an e-mail e.g . by filling in missing headers and things like that . Comment : +1 for the great information thanks Dark Dust", "Question : I m building a application that needs to send and receive emails . However I do not want to have a separate email server or use IMAP and POP3 since I need to create delete manage inboxes on the fly with no email inbox passwords etc . I have an email storage database in-place and I can receive emails by using a custom smtpd server replacing postfix . However that way I m not able to send emails via postfix using smtplib connecting through port 25 to postfix and sending emails .. . .. . Any solution to this problem How to send emails with a custom smtp server Can I configure postfix to relay all incoming emails to a custom smtp server running in another port and still use postfix on port 25 to send emails Thanks for your time .. . Answer : By using a custom SMTP server you run the risk of inadvertently creating security holes or violating the SMTP protocol in some way . With so many great SMTP servers out there Postfix exim sendmail.. . that doesn t sound like a good option to me . The easiest way I can think of to solve that issue is to use Postfix to relay inbound and outbound e-mail . Inbound e-mail can be configured to be piped to an application and outbound e-mail can be configured to be delivered by Postfix either directly or relayed through a different server . This way you can use instead of a custom SMTP server an application that is able to parse RFC822-compliant message files . This is better than doing exactly the same thing but with the overhead of having to implement the SMTP protocol . This approach probably won t scale well should you need to receive a high volume of messages - every message will fork+exec a new process . If that is a requirement a good approach would be to keep a custom SMTP server to do that job but let Postfix relay it the messages - you will then benefit from Postfix s architecture in front of your parser . Assuming you follow the approach of piping the messages to an application all you need to do in Postfix is to .. . .. . 1 . Configure Postfix s alias maps http : www.postfix.org postconf.5.html alias maps parameter to look for such a map : .. . .. . alias maps hash : etc aliases hash : etc postfix app-aliases .. . .. . .. . 2 . Then configure the map to pipe messages sent to each address into an application : .. . .. . test : usr local bin your-app .. . .. . .. . 3 . As usual don t forget to postalias app-aliases . This will make a message sent to test@yourdomain be piped into usr local bin your-app which acts as an e-mail gateway to your application . Comment : Meanwhile this came up http : elspy.sourceforge.net that should also do the trick by directly getting the emails from the Mail Transfer Agent incoming queue . I ll check both alternatives and see which is better . Comment : That looks more like a scanner module than an MDA .

Decide what you want to learn the details of : headers protocols and bytes or buttons and notifications .. . Answer : The Python language does offer raw support for the needed protocols in its standard-library . Properly using then and properly parsing and assembling a modern day e-mail message however can be tough to do . Also you didn t say if you want to create a graphical interface for your e-mail client -- if you want to have a proper graphical interface -- up to the point of being usable it is quite a lot of work . Local e-mail storage would be the easier part - unless you want to properly implement an mbox file-format RFC-4155 http : tools.ietf.org html rfc4155 so that other software can easily read-write the messgaes you have fetched you can store them in as Python Objects using an ORM or an Object Oriented database such as ZODB or MongoDB . If you want more than a toy e-mail app you will have a lot of work - properly encoding e-mail headers for example server authentication and secure authentication and transport layers decoding of the e-mail text body itself for non ASCII messages . Although the modules on the Python standard-library do implement a lot of that their documentation falls short on examples - and a complete e-mail client would have to use all of then . Certainly the place to start an e-mail client even a toy one would be taking a look on the most recent RFC s for e-mail and you will have to pick then from here http : www.ietf.org rfc rfc-index since just looking for email rfc on google gives a poor result .

You can get more info here : mozilla.org en-US firefox channel aurora http : www.mozilla.org en-US firefox channel aurora Comment : But why it s better for debugging Does it have a better debugging tool Comment : @SharonHaimPour Yes in every new release it s becoming better and with more features .", "Question : It would be extremely helpful for developing Firefox extensions if I could see the source of e.g . chrome : browser content browser.xul with overlays applied . Is there a way to do this Chrome List https : addons.mozilla.org en-US firefox-addon 4453 and View Source show only the base structure ChromeBug http : getfirebug.com releases chromebug requires restarting the browser and isn t too easy to get working . Comment : Does the DOM inspector not show the overlays applied .. . Answer : All you need is DOM Inspector https : addons.mozilla.org en-US firefox-addon 6622 and I highly recommend pairing that with Inspect Context https : addons.mozilla.org en-US firefox-addon 3276 which adds an Inspect option to the right-click menu of almost everything much like the Inspect Element option of Firebug .", "Question : Using ColorZilla http : www.colorzilla.com I found an interesting feature .

Then I can see the markup css js that firefox uses in the firebug panel just like a website . enter image description here http : i.stack.imgur.com tUFDO.jpg .. . .. . Is there any solution to view this code without use Colorzilla .. . Answer : As mentioned in the comments Chromebug is no longer working with current Firefox versions . Instead of opening the limited chrome : browser content browser.xul page you can make the browser chrome accessible to the scratchpad . Open the about : config page and set devtools.chrome.enabled to true as described in the extension development-environment setup https : developer.mozilla.org en-US docs Setting up extension development-environment guide on MDN . Open the JavaScript scratchpad Shift+F4 and select the browser context environment . Now you can type in something like window or document.getElementById urlbar and click the inspect button or hit Ctrl+i . This will evaluate the expression and open the element inspector which shows all properties of the element .", "Question : I m trying to run a hosted script with content privileges in my Firefox extension . To do this I create a content iframe in the hidden window pointed at a html file that pulls the script . This script requires the history be available but the iframes created in the hidden window have no history for some reason . Chromebug reports this for the iframe s contentWindow.history : .. . .. . object does not support history nsIDOMHistory .. . .. . And the script gives this error when its not available : .. . .. . Error : Component returned failure code : 0x80004005 NS ERROR FAILURE nsIDOMHistory.length .. . .. . Any ideas .. . Answer : A browser type content will automatically wire up session history by default while an iframe type content will not but you could always wire it up yourself manually . Don t forget to ensure that your element is created in the XUL namespace . I believe the hidden window is the about : blank HTML document except on the Mac . Comment : I ve tried this with the same result . Here was the code I used for that where doc is the hidden window s document . var browser doc.createElementNS XUL NS URI browser browser.setAttribute type content browser.setAttribute disablehistory false browser.setAttribute src url doc.documentElement.appendChild browser Comment : I seem to have a history object attached to the xul browser but an exception is thrown each time I try to use .back or go -1 . Do you have any idea what could be causing it", "Question : Is there a convenient way to do this for my extension I know I can use FireBug to get traces for exceptions which happen in content but I don t think it works for chrome does it . I couldn t get ChromeBug to work when I last tried it . .. . Answer : Have you tried checking the Show Chrome Errors and Show Stack Trace with Errors options in the Console menu of Firebug 1.5 They might be in earlier versions too . If your extension is for Firebug itself this post on Firebug tracing http : www.softwareishard.com blog firebug tracing-console-for-firebug should be helpful .", "Question : I m trying to run a hosted script with content privileges in my Firefox extension .

Chromebug reports this for the iframe s contentWindow.history : .. . .. . object does not support history nsIDOMHistory .. . .. . And the script gives this error when its not available : .. . .. . Error : Component returned failure code : 0x80004005 NS ERROR FAILURE nsIDOMHistory.length .. . .. . Any ideas .. . Answer : It turns out that the hidden window s URL used to be about : blank but this was apparently a security flaw so it is now resource : gre res hiddenWindow.html or resource : gre-resources hiddenWindow.html on trunk so it doesn t have the chrome privileges that a XUL browser element needs in order to be able to wire up its own session history or even to access its own content document . Even using a XUL iframe element you have to be careful since none of its properties work again because it is running without chrome privileges . So you have to do stuff like iframeElement.boxObject.QueryInterface Components.interfaces.nsIContainerBoxObject .docShell.QueryInterface Components.interfaces.nsIInterfaceRequestor .getInterface Components.interfaces.nsIDOMWindow to retrieve its content window . Comment : Trying to edit in an update to my post but stack-overflow is giving errors when I try . You re right about the hidden window . My extension has a chrome iframe in the hidden window used as a singleton js context . I can embed the browser there and wire in the sessionHistory manually . It works Thank you .", "Question : When I build a newsletter and send it to myself as a test I would like to be able to analyze the resulting HTML in my email-client Thunderbird .

Comment : @People Who Downvoted It : I don t see why you guys randomly down vote a question without having the decency of explaining the reason of having done that . I think it s a pretty important question . Read the stack rules . Comment : @adeneo : Can give me a few pointers as to how i can obfuscate it using SSL . Some examples perhaps.. . Comment : @TheDarkKnight It might help if you could explain why you want to do this . .. . Answer : The source of the page is what is delivered to the browser to be rendered . Because of that anything that you want to present to the end user in the browser will be visible in some way in the source code . There are no work-arounds here . If it is displayed in the browser the end user has access to it in one way or another . If your goal is to not show the whole PAN card number that should be done on the server-side before it s delivered to the browser . In this case you make sure that the PAN CARD NO variable only contains something like xxxxxxx7654 . With this method full PAN card number is never delivered to the end user . If your goal is to prevent unauthorized users from viewing the PAN card number then you need to make sure that you only deliver the card number for the authenticated user . This will require you to have the user authenticate themselves to the server in some way e.g . logging in ." ] }	[ "yes-answer-long", "yes-answer-short" ]	thunderbird	UNK_RELATION

Redis Cluster design says that it does not use consistent-hashing but a different form of sharding where every key is conceptually part of what is called as hash slot . There are 16384 hash slots in Redis Cluster and to compute what is the hash slot of a given key we simply take the CRC16 of the key modulo 16384 . Every node in a Redis Cluster is responsible for a subset of the hash slots so for example we have a cluster with 3 nodes where : .. . 1 . Node A contains hash slots from 0 to 5500 . 2 .

It turns our that this utility does not handle password-protected redis servers . .. . Answer : redis-trib.rb cannot handle Redis nodes which are password-protected . So trying to use it on such nodes would result in ERR Sorry can t connect to node . Why the redis-trib.rb utility does not handle authenticated nodes It has to do with the fact that when a Redis node is password protected only the communication on its main port by default 6379 is protected . The communication on its cluster bus Default Port + 10000 16379 where nodes in a cluster communicated with each other is not protected . So a Redis cluster is not really password-protected when individual nodes are . So having a password on individual Redis nodes in a Redis cluster adds little security value . Therefore the redis-trib.rb utility has not implemented any authentication .

My application is a bit complex and I want to basically control to which partition data from my application goes . For example my application consists of sub-module A B C . Then I want that all data from sub-module A should go to partition 1 for example . Similarly data from sub-module B should go to partition 2 for example and so on . I am using JedisCluster but I don t find any API to write to a particular partition on my cluster .

I tried going through the JedisCluster lib at .. . .. . https : github.com xetorthio jedis blob b03d4231f4412c67063e356a7c3acf9bb7e62534 src main java redis clients jedis JedisCluster.java .. . .. . but couldn t find anything . Please help Thanks in advance for the help . .. . Answer : That s not how Redis Cluster works . With Redis Cluster each node partition has a defined set of keys slots that it s handling . Writing a key to a master node which is not served by the master results in rejection of the command . From the Redis Cluster Spec http : redis.io topics cluster-spec keys-hash-tags : .. . .. . Redis Cluster implements a concept called hash tags that can be used in order to force certain keys to be stored in the same node . .. . .. . .. . .. . The key space is split into 16384 slots effectively setting an upper limit for the cluster size of 16384 master nodes however the suggested max size of nodes is in the order of 1000 nodes . Each master node in a cluster handles a subset of the 16384 hash slots . You need to define at Cluster configuration-level which master node is exclusively serving a particular slot or a set of slots . The configuration results in data locality . The slot is calculated from the key . The good news is that you can enforce a particular slot for a key by using Key hash tags http : redis.io topics cluster-spec keys-hash-tags : .. . .. . There is an exception for the computation of the hash slot that is used in order to implement hash tags . Hash tags are a way to ensure that multiple keys are allocated in the same hash slot . This is used in order to implement multi-key operations in Redis Cluster . Example : .. . .. . The content between is used to calculate the slot . Key hash tags allow you to group keys on particular nodes and enforce the same data locality when using arbitrary hash tags . You can also go a step further by using known hash tags that map to slots you d need either precalculate a table or see this Gist https : gist.github.com mp911de 5f9890496faca01b0ff9 . By using known hash tags that map to a specific slot you re able to select the slot and so the master node on which the data is located . Everything else is handled by your Redis client .

When needed to redirect to another cluster node it shows Redirected to slot 7785 located at 127.0.0.1 but should show Redirected to slot 7785 located at IP of PC1 like 192.168.1.20 then it shows an error .

Answer : That is because all your Redis IP addresses have updated to 127.0.0.1 and they believe other Redis are located in 127.0.0.1 too . That s not wrong if nodes in a cluster just communicate with each other but definitely improper when a connection from other host want to know about the cluster . In that situation your client asked a Redis for a key it s not in charge and the Redis told the client to redirect to 127.0.0.1 : 30003 . The client misunderstood it and tried to connect the port 30003 in its localhost and certainly found nothing . To fix it try to send cluster meet with the right IP to each Redis in the cluster . I ve made an experiment like this .. . .. . In your case you may send multiple cluster meet commands to each Redis to ensure its IP updated at all its peers . Comment : I think so . But in product server how can I do this It should has configure to set is t it Comment : I use the official redis-trib.rb file to create the cluster maybe it s the reason The command is : redis-trib.rb create --replicas 1 127.0.0.1 : 30001 127.0.0.1 : 30002 127.0.0.1 : 30003 127.0.0.1 : 30004 127.0.0.1 : 30005 127.0.0.1 : 30006 is here should be 192.168.1.20 not be 127.0.0.1 Comment : @RobinChen No the nodes list is a dynamic config stored in the file specified by cluster-config-file . But you don t have to edit it manually or restart any of the redis-servers . Sending cluster meet commands via redis-cli will do . Comment : @RobinChen That would surely cause the problem . You are supposed to use 192.168.1.20 the eth0 address in the first place .

In this tutorial I need to run several redis-server instances on port 7000 through 7005 . However after I run the first instance successfully and try to run the second instance the nodes.conf file seems to be locked and I get the following error message : .. . .. . Sorry the cluster configuration file nodes.conf is already used by a different Redis Cluster node . Please make sure that different nodes use different cluster configuration-files . Do I need a separate nodes.conf for every server instance Or do I need a separate redis-server executable in each instance directory and run it from there .. . Answer : The tutorial suggests you to use separated folders for each instance configuration so each instance will also generate the nodes.conf on its own folder . Create a redis.conf file inside each of the directories from 7000 to 7005 . You need to have the .conf files on separated folders for each instance and the executable must be ran from that folders . Assuming you have the redis-server on tmp redis-cluster and the redis.conf on each tmp redis-cluster 700x folder : .. . .. . This way the nodes.conf will be generated on the current folder 7000 . Note that you must first issue a cd to change the current directory and from that folder execute the redis-server that is one folder up . . Comment : This is exactly what I do . The problem is that the redis-server is outside the 7000 etc . directories and the nodes.conf file which it uses for the cluster configuration is shared when the different servers are started . So I think the tutorial should be edited because the way it is described it does not work . Comment : I don t think this the problem is in the tutorial . Many of us has followed the tutorial without any problem . Can you share your folder structure and how do you exactly run the instances Comment : I have the redis-server in a folder tmp redis-cluster . Then I have the different redis.conf files in these folders : tmp redis-cluster 7000 tmp redis-cluster 7001 tmp redis-cluster 7002 tmp redis-cluster 7003 tmp redis-cluster 7004 tmp redis-cluster 7005 . Then I run each server with these commands tmp redis-cluster redis-server . 7000 redis.conf etc . Once the cluster is created when I try to start the servers again they start complaining about a lock on the nodes.conf file which is located in the tmp redis-cluster directory . Comment : You should run the instances like this : cd tmp redis-cluster 7000 . . redis-server . redis.conf . I just edited my answer . Comment : This worked I did not realize that the current directory will be one where the server will generate the nodes.conf . Thanks .", "Question : So I am testing out the redis-cluster . I have a setup with 3 masters and 3 slaves . Now in case a node faces hard-failure both master and slave go down the cluster is still functional barring the hash slots served by the failed node .

What is the best way then to deal with a scenario where I cannot bring my original node up but want those hash slots to be served by some other node assuming that I am even fine with losing data on the old node Ideally something like being able to remove that node master and slave from the cluster and assign those hash slots to some other node .

If it still doesn t work would you please post more details about the cluster like the output of a cluster nodes .. . Answer : It fixes the cluster by adding all slots that was served by the failed node to some connectable nodes .

The current LCDS based application is using only RPC functionality which is present in BlazeDS as well . I read over the internet that both LCDS and BlazeDS are being developed by Adobe now . I downloaded the BlazeDS turnkey demo application and found that even the libraries under the lib folder are the same as that of my current LCDS based application . Furthermore APMO the way configurations are done in remoting-confix.xml service-config.xml are also same . My question is : .. . .. . 1 . If everything seems same in LCDS RPC and BlazeDS RPC then where is the difference or am I missing something crucial here 2 . Also if both LCDS and BlazeDS are developed by Adobe and the libraries are same then is there any real need to change the application from LCDS to BlazeDS . I know LCDS is paid and BlazeDS is free but I don t understand where will I make changes in the application to make it BlazeDS if the libraries are same in both cases 3 . Finally is there any difference how we create call RemoteObject in LCDS and in BlazeDS Kindly reply . Thanks . .. . Answer : LCDS has more features that are not present in blazeds and is designed to be more scalable . if you are not using any specific feature to LCDS then its painless to move to blazeds . for most apps non enterprisey apps blazeds will do just fine . remoteobject calls are the same . there is also graniteds as another option .", "Question : null .. . Answer : I have an Adobe Air 2.0 application that is also utilizing Spring BlazeDS integration . Inside this application I have a couple of data grids . The design was for each grid s model to register a Consumer to listen for changes pushed from BlazeDS . The first grid instantiated works correctly however each subsequent grid causes the following warning in BlazeDS .. . .. . I was under the impression you could have multiple consumers inside a Flex Air application . Am I mistaken or have I just missed something in my configuration Server side channel definition .. . .. . Code for Channelset .. . .. . Code for Consumer Comment : Ok based on what I have seen so far it would appear that you cannot have more than one streaming AMF consumer at a time unless you instantiate the multiple consumers at the same time . If I change the channelset to use long-polling the code works as expected . At this point I have decided to use a single consumer and route all of my critical messages through that consumer . I will use long-polling consumers for less real-time updates where possible . If no one else comments within a couple days I will accept this as the answer .", "Question : I m doing a tech review and looking at AMF integration with various backends Rails Python Grails etc . Lots of options are out there question is what do the Adobe products do BlazeDS etc that something like RubyAMF pyAMF don t .. . Answer : Adobe has two products : Livecycle Data Services ES LCDS and BlazeDS . BlazeDS contains a subset of LCDS features and was made open-source . Unfortunately NIO channels RTMP NIO HTTP and the DataManagement features are implemented only in LCDS not BlazeDS . BlazeDS can be used only to integrate Flex with Java backend . It offers not only remoting services using AMF serialization as RubyAMF but also messaging and collaboration features - take a look at this link http : livedocs.adobe.com blazeds 1 blazeds devguide help.html content lcoverview 3.html .

Answer : Adobe has donated BlazeDS to the Apache Flex community and the source code is hosted on the Apache Flex website in a GIT repository . http : flex.apache.org dev-sourcecode.html .. . .. . There is a forum with a commits section for BlazeDS that might add a historical viewpoint on the previous code changes but it does appear that Apache only received a commit of the latest release and started editing from there . https : forums.adobe.com community opensource blazeds https : forums.adobe.com community opensource blazeds commits", "Question : As far as In understand the Flex http : en.wikipedia.org wiki Adobe Flex technology a Flex client connects to a Flex server to retrieve business information .

What could prevent a client from conenctiong to a BlazeDS server is the crossdomain.xml http : www.google.ch search aq 0 oq crossdomain sourceid chrome ie UTF-8 q crossdomain.xml which is a connection policy document hosted on the server . I ve got one concern about your question and that is using the term Flex server . That was something folks talked about with Flex 1 circa 2005 Adobe is now on Flex 4 and some relevant server technologies platforms software protocols of interest are BlazeDS Red5 http : osflash.org red5 FMS LiveCycle Data Services http : www.adobe.com products livecycle dataservices JSON http : www.json.org AMF3 http : www.google.ch search sourceid chrome ie UTF-8 q amf3 etc .

Comment : @mjustin : Please re-read that link . The subject is much more complex there are options . Also note that article is old--It is referencing Flash 7 The devil is in the details it can be done many folks are doing it . Comment : Thank you for your hint see my update - accepted your answer", "Question : Evenin good people I m creating a virtual whiteboard application for my third year project at university . The system uses a Flex front-end and a Spring BlazeDS back-end . I d say that I m pretty new to BlazeDS and to Flex so apologies if anything I say doesn t make a lot of sense . I m attempting to implement a reasonably secure server-push from Spring BlazeDS to the Flex application based on groups whiteboards . I ve discovered that BlazeDS offers a publish-subscribe messaging architecure which includes support for sub-groups . However I can t find a way of restricting access to particular password-protected groups available only to users pre-authenticated with the system . my system is also using a custom log-in process mediated through Flex RPC calls . Additionally I ve considered writing a custom messaging-adapter however getting this to @autowire with the rest of my project and a custom authentication system has proven difficult and so far I ve had little success . All-in-all I m at a little bit of a loss for how to continue . Any help would be greatly appreciated . .. . Answer : If I understand your problem currectly you are trying to implement Authorization based subscriptions . The user can subscribe to a group only if he is authorized to so If so Flex has a concept of subtopics the client subscribes on to a destination with this subtopic . This subscription can be manually managed by extending Adapters in flex . override a couple of methods to do so . when the client requests for subscribe on this subtopic handle the subscription in the adapter maintain a list of subscriptions also there is an overriden method in the same adapter to handle the push of the messages you can use it to find the authorization of the user and push messages accordingly . these methods are not invoked by you directly thre are classes in blazeds to construct the message objects and pushe it to the client i think it is AsyncMessage use this to push . Its been a long time since I worked on this I hope you got some direction . Comment : This actually sounds more or less like the route I chose in the end . I posted this question a while ago so I had a bunch of time since then to do a little more reading . Thanks for your input though .", "Question : I ve seen a bunch of screencasts demonstrating the integration between blazeds and flex also some lcds tutorials model-driven or not . I ve seen that some of them the presenter opens 2 browsers and once you change one value in a grid it propagates to all other grids that presents the data . I am wondering how the heck this is done and how to reproduce . Does this feature depends of the Edge LCDS solution I don t think so but I ve never seen some code explaining about it . I feel it may or may not rely on JMS MQ messaging protocols or if this is some sort of 2 way sync and propagation of collection between instances of the same service result . Thanks for any inputs . Cheers .. . .. . Ernani .. . Answer : You can implement this feature both with BlazeDS and LiveCycle Data Services . BlazeDS provides remote and messaging features the messaging features is the one allowing you to synchronize the data between the clients LCDS extends BlazeDS adding new features like data management productivity improvements PDF generation EDGE server for dealing with DMZ zones MDA development portal integration etc . It also adds some advanced messaging features like message conflation throttling reliability . BlazeDS is free and open-source and in my opinion a robust solution you can use it if you want to synchronize the data between clients . LCDS adds a lot of things but the LCDS customers should have a large budget . How does it work There is no JMS behind for this feature however BlazeDS can integrate with a JMS provider so you can have one client in broswser and the second one running a SWING application . Instead there are some message queues on the server and a publisher - subscriber graph . In order to push the data from the clients to the server there are several choices the more advanced are available only on LCDS : HTTP polling HTTP long-polling HTTP streaming RTMP sockets LCDS only . All of them are described in details on Damon http : www.dcooper.org blog client index.cfm mode entry entry 942B63DD-4E22-1671-5B4CF844C30A0E98 blog . If you want to see some code go and download BlazeDS http : opensource.adobe.com wiki display blazeds Downloads and take a look on the samples there are several ones showing the messaging features . Also there a tomcat server is bundled in the download and the samples are already deployed in it . Comment : Great answer . I d also like to add that there are some live samples of the Messaging and Data Management features in Tour de Flex : flex.org tour http : flex.org tour The Data Management samples might be broken at the moment due to the database being down . But the TDF team is working to resolve that . Comment : Thanks great answer indeed so in order to resume this question this is only doable using a MQ endpoint I thought of managing this with RemoteObjects only but it seems impossible right Comment : Yes it is..download the Spring BlazeDS Integration Samples static.springsource.org spring-flex docs 1.0.x reference html http : static.springsource.org spring-flex docs 1.0.x reference html ch06.html and you will find a sample using ActiveMQ . Yes it is almost impossible you need to use the producers and the consumers objects . Almost impossible means that you can do something by implementing your own polling based on periodic remote calls but it is overkill . Comment : I ve managed to make some test situation using a custom polling interval request using timers but this is duct-taping programming I feel that using JMS is far better and will seek for the best .

Would it be possible to also recieve the message you send in that same class", "Question : BlazeDS is implemented as a servlet and thus limited to roughly hundreds of simultaneous users . I wonder if the more recent web containers Tomcat 7 GlassFish Grizzly Jetty etc . supporting Servlet 3 could be used to create NIO endpoints to increase the number of simultaneous users to the thousands Is this a valid and practical solution Anyone do this in production Something like a mature version of this : http : flex.sys-con.com node 720304 If this was of great importance back then why now when Servlet 3 is widely available has there been no effort to try to implement NIO endpoints note I m a newbie here so feel free to state the obvious if I m missing something .. . .. . Benefit of NIO : http : www.javalobby.org java forums t92965.html .. . .. . If not is a load balancer and multiple application servers each having an instance of BlazeDS the recommended solution outside of going to LCDS etc . .. . Answer : GraniteDS Asynchronous Servlets .. . .. . GraniteDS is as far as I know the only solution that implements asynchronous servlets for real-time messaging ie . data push . This feature is not only available for Servlet 3 containers Tomcat 7 JBoss 7 Jetty 8 GlassFish 3 etc . but also for older or other containers with specific asynchronous support eg . Tomcat 6 CometProcessor WebLogic 9+ AbstractAsyncServlet etc . Other solutions don t have this feature BlazeDS or use RTMP LCDS WebORB and the last version of Clear Toolkit . I can t say much about RTMP implementations but BlazeDS is clearly missing a scalable real-time messaging implementation as it uses only a synchronous servlet model . If you need to handle many thousands concurrent users you can even create a cluster of GraniteDS servers in order to further improve scalability and robustness see this video http : www.youtube.com watch v aRLZcU-m6G8 for example . Asynchronous Servlets Performance .. . .. . The scalabily of asynchronous servlets vs . classical servlets has been benchmarked several times and gives impressive results . See for example this post http : blogs.webtide.com gregw entry comet performance on the Jetty blog : .. . .. . With a non NIO or non Continuation based server this would require around 11 000 threads to handle 10 000 simultaneous users . Jetty handles this number of connections with only 250 threads . Classical synchronous model : .. . .. . 10 000 concurrent users - 11 000 server threads . 1.1 ratio . Comet asynchronous model : .. . .. . 10 000 concurrent users - 250 server threads . 0.025 ratio . This kind of ratio can be roughly expected from other asynchronous implementations not Jetty and using Flex AMF3 instead of plain text HTTP request shouldn t change much of the result . Why Asynchronous Servlets The classical synchronous servlet model is acceptable when each request is processed immediately : .. . .. . The problem with data push is that there is no such thing as a true data push with the HTTP protocol : the server cannot initiate a call to the client to send data it has to answer a request . That s why Comet implementations rely on a different model : .. . .. . With synchronous servlet processing each request is handled by one dedicated-server thread . However in the context of data push processing this thread is most of the time just waiting for available data and does nothing while consuming significant server resources . The all purpose of asynchronous processing is to let the servlet container use these often idle threads in order to process other incoming requests and that s why you can expect dramatic improvements in terms of scalability when your application requires real-time messaging features . You can find many other resources on the Web explaining this mechanism just google on Comet . Comment : Thanks Franck for the detail response . I ll edit my post above to focus on BlazeDS . Comment : Franck should know it But it is also possible to use BlazeDS with Jetty8 NIO Servlet 3.0 and clustering with JGroups . We have done this several times with Jetty7 and now with Jetty 8-RC5 and the results are not bad .

Comment : This is the Spring s integration library for BlazeDS not the BlazeDS code by Adobe . Comment : @BenNeill I thought so too initially but they actually packaged up the Adobe jars inside their own local repository note the local-repo at the end of the URL probably because the BlazeDS Installation Guide http : sourceforge.net adobe blazeds wiki BlazeDS 204.0 20Installation 20Guide is such a joke .", "Question : Is there any reliable way to check statistics for this question I m skeptical whether measures like Google Trends really say much but I was thinking the job market for Flex jobs might be an indicator and the market seems healthy http : www.indeed.com jobtrends q 22adobe 2Bflex 22 2C 2Bactionscript l based on Indeed Trends . I thought adoption of Adobe Flex was relatively sluggish but what I m hearing is that this has changed because of open-source BlazeDS . I would like to verify this because I have an interest in Flex but was avoiding it because it seemed to be a market failure . Any info would be appreciated even if it s anecdotal . .. . Answer : The barrier to adoption of Flex has always been the requirement of Flash Player and the feeling by many that developing with it isn t standards-based and instead opt for an DHTML AJAX solution . Therefore I don t think that Blaze DS is going to push a large number of people towards Flex-based RIAs . Even before Blaze you could write some pretty large-scale applications using of XML-based services RPC SOAP RESTful . It only became problematic from a performance issue when you were dealing with some very large-data sets thousands of large records at a time . Blaze is also a Java-only solution and there are lots of other types of backend technologies being used with Flex : PHP .NET Python Ruby ColdFusion etc . Speaking to the market I can tell you that I joined one of the largest Flex shops in the world about three years ago and have seen our company grow at least 5x during that period due almost exclusively to increased demand for Flex . We are also seeing significant growth with Silverlight and WPF as Microsoft rolls out these solutions to their huge developer community . Either way I think that player-based RIA is a lot more than a flash in the pan no pun intended and is going to continue to experience incredible growth . The web browsers won t be able to keep pace with the innovation of the player-based runtimes and HTML 5 is nowhere in sight .", "Question : I m trying to create a module for a flex application and I want to send notifications to clients .

Changing the build procedure is not really an option so I would like to find an alternative method if possible . Comment : Could you be more specific as to why escaping the quotes does not work in the real project It is hard to provide solutions with an unknown requirement . Comment : OK I still don t get why the solution from the linked question define STRINGIFY x x wouldn t work for you . .. . Answer : Your attempt to use the well-known stringification recipe of the C preprocessor viz : .. . .. . fails for two reasons each sufficient by itself . First and simplest the source file in which you attempt to employ it apparently has the extension .f90 . What this extension signifies to gfortran and to the GCC compiler driver by any other name is : Free form Fortran source code that should not be preprocessed . Similarly .f95 .f03 and .f08 . If you want gfortran to infer that a source file contains free form Fortran code that must be preprocessed give it one of the extensions .F90 .F95 .F03 or .F08 . See the GCC documentation of these points https : gcc.gnu.org onlinedocs gcc Overall-Options.html Overall-Options .. . .. . Even if you do that simple thing however the second reason bites . The use of the C preprocessor to preprocess Fortran source is as old as C which though old is much younger than Fortran . gfortran is obliged not to break ancient working code so when it invokes the C preprocessor it invokes it in traditional mode . The traditional mode of the C preprocessor is the way in which the preprocessor behaved prior to the first standardization of the C language 1989 insofar as that unstandardized behaviour can be pinned down . In traditional mode the preprocessor does not recognize the stringizing operator which was introduced by the first C Standard . You can verify this by invoking the preprocessor directly like : .. . .. . where test.c contains some attempt to employ the stringification recipe . The attempt fails . You cannot coax gfortran on its own to work the the stringification recipe . But there is a workaround . You can invoke cpp directly unencumbered by traditional mode to preprocess the Fortran source in which you want the stringification done and relay its output to gfortran . If you already know this and were looking for a gfortran -alone solution you need read no further . Doing the stringification in your test source this way would look like : .. . .. . The output of that is : .. . .. . And that output is what you want to to compile . You could accomplish that as well by : .. . .. . Then you will find that . test exists and that executing it outputs hello . You can eliminate the intermediate temporary file with further refinement . Your F90 source code will compile as F95 as the latter is conservative of the former . So you can take advantage of the fact that GCC will compile source piped to its standard input if you tell it what language you are piping using its -x language option . The Fortran dialects that you may specify in this way are f77 f77-cpp-input f95 and f95-cpp-input where the -cpp-input prefix denotes that the source is to be preprocessed and its absence denotes that it is not . Thus .. . .. . works as well as the previous solution minus the temporary file and emits the innocuous warning : .. . .. . Note and retain the final - on the commandline . That is what tells gfortran to compile the standard input . . The meaning of -x f95 brings the additional economy that the source which is preprocessed by cpp is not preprocessed again by the compiler . The use of the option -std c89 when invoking cpp calls for a cautionary explanation . It has the effect of making cpp conform to the earliest C Standard . That is as close to -traditional as we can get while still availing of the -operator on which the stringification recipe depends But with it you embrace the possibility of breaking some Fortran code if you preprocess it this way otherwise gfortran itself would not enforce -traditional . In the case of your test program you could safely omit -std c89 allowing cpp to conform to the default C standard when it was built . But if you permit it or direct it to conform to -std c99 or later then the standard will mandate recognition of as the beginning of a one-line comment as per C++ by which any line of Fortran that contains the concatenation operator will be truncated at the first occurrence . Naturally if you use are using make or another build-system to build the code in which you want the stringified macros you will have a way of telling the build-system what actions constitute compiling a given class of compilable files . For any Fortran source file fsrc you wanted to compile with a stringification preamble the actions to specify would be in the vein : Comment : Thank you for writing such a comprehensive answer . In response to your first point that was just a typo on my part -- I was using the .F90 suffix rather than .f90 . I have edited the question to reflect this . On the second point you have answered my question with You cannot coax gfortran on its own to work the the stringification recipe . It looks like I am either going to have to find a different way to do what I want or convince the project owner to modify their build procedure . The remainder of your second answer gives me a solution to offer . Thanks again .", "Question : Using Pelles C I would like to show or log an unsigned char array .

Answer : Because of the order of expansion . The GCC documentation http : gcc.gnu.org onlinedocs gcc-4.6.1 cpp Argument-Prescan.html says : .. . .. . Macro arguments are completely macro-expanded before they are substituted into a macro body unless they are stringified or pasted with other tokens . After substitution the entire macro body including the substituted arguments is scanned again for macros to be expanded . The result is that the arguments are scanned twice to expand macro calls in them . So if the argument will be stringified it is not expanded first . You are getting the literal text in the parenthesis . But if it s being passed to another macro it is expanded . Therefore if you want to expand it you need two levels of macros . This is done because there are cases where you do not want to expand the argument before stringification most common being the assert macro . If you write : .. . .. . you want the message to be : .. . .. . and not some insane thing the MIN macro expands to in gcc it uses several gcc-specific extensions and is quite long IIRC .", "Question : Given define LOG OBJECT object NSLog @ object @ @ @ : d object description NSString stringWithUTF8String : FILE lastPathComponent LINE The statement LOG OBJECT self will produce : .. . .. . 2014-07-18 17 : 43 : 30.041 FrogCamera 12484 : 2144843 self ViewController.m : 20 .. . .. .

Adding parenthesis around every macro is a good programming convention to prevent this type of errors . 2 . param is a stringification operator . It wraps the parameter in quotes - e.g . parameter value is converted to value . 3 . The stringification operator creates a C string which is an array of characters char . The author wanted a NSString that s why he is adding an @ in the beginning . Note that @ aaa bbb is equivalent to @ aaabbb this feature enables us to split strings over multiple lines . However this is not very elegant . Using a s would make it a bit simpler . 4 . It is converted only to @ self @ @ @ : d .

I realize there s no way to really access the individual arguments from within the macro definition but is there a way to stringify all the arguments with maybe something like the following .. . Answer : Okay I didn t mean to answer my own question here but I ve come up with a decent solution that is somewhat of a combination of Mark Wilkins answer and the example I gave in the question . It is possible to stringify the entire set variadic set which then includes the delimiting commas in the string . Here s a quick example : .. . .. . Using the above macro shows you that the entire set of arguments passed to the macro gets stringified . Then you can then define a function to tokenize these arguments using the delimiting comma thereby getting the set of tokenized strings by using the variadic-macro : .. . .. . Then there s actually no longer the dependency of having the variadic-macro call a variadic function and I can iterate nicely through my array of constant C strings rather than iterating through va arg . New Stuff from Edit Follows .. . .. . Per Tim s comment here s the details of the solution . Please forgive any errors since it was done in haste and I had to port from what I m working on . Also it s not meant to be copy-paste solution since it only outputs the stringification of the arguments to demonstrate POC but should be sufficient enough to demonstrate the functionality . Although this solution requires some run time computation variadic macros often times call variadic functions and requires iterating through va args so the iteration takes place in finding the tokens although a bit of performance is probably sacrificed . However for maintainability versatility and ease of implementation this seems to be the best option at the moment : Comment : Also another nice feature of this is that I can easily find the number of arguments without having to have some type of information passed through the macro to determine where the arguments in the list ends .

If you want to stringify the result-of expansion of a macro argument you have to use two levels of macros . s is stringified when it is used in str so it is not macro-expanded first . But s is an ordinary argument to xstr so it is completely macro-expanded before xstr itself is expanded . Therefore by the time str gets to its argument it has already been macro-expanded . This happens because of the preprocessor s rules for prescanning macro arguments which are explained here https : gcc.gnu.org onlinedocs cpp Argument-Prescan.html Argument-Prescan : .. . .. . The important point from that page is : .. . .. . Macros that call other macros that stringify or concatenate . .. . If an argument is stringified or concatenated the prescan does not occur . If you want to expand a macro then stringify or concatenate its expansion you can do that by causing one macro to call another macro that does the stringification or concatenation .

Comment : Macro expansion happens long before the compiler gets involved . Comment : @litb : a nice hack but why don t you post it as answer so I can upvote that : .. . Answer : You could use some template magic . This has an advantage over RTTI i.e . typeinfo - it is resolved during compilation and disadvantage - you need to provide type information yourself unless there is some library that does that already that I m not aware of maybe something in Boost even . Or as Matrin York http : stackoverflow.com users 14065 martin-york suggested in comments use inline function-templates instead : .. . .. . But if you ll ever need to store more information about that particular type then class templates will probably be better . Comment : Rather than building variables . Build inline-functions that return the appropriate string . Then you will not have the problem of multi-definintions that may crop up with this method . Comment : Good idea I ve edited my answer .

Answer : mat-vec multiplication is a standard BLAS https : en.wikipedia.org wiki Basic Linear Algebra Subprograms operation . However your data type is not a standard one float or double . So it may not be the best choice to convert your data to double use BLAS routines like gemv http : docs.nvidia.com cuda cublas cublas-lt-t-gt-gemv and convert the result back to long-long . Alternatively you could create your own CUDA kernel or use Thrust https : thrust.github.io to avoid writing kernel code but with some performance degrade . You could start from this example https : github.com thrust thrust blob master examples sum rows.cu to see how to sum a matrix row-by-row into a column vector which is the second step for mat-vec-mul operation after you finish the element-wise multiplication between each row the matrix and the vector .

Is it possible to use thrust in order to sort an array of OB according to N Can you provide a simple example on using thrust to sort objects If thrust is not able to do so is there any other CUDA libraries that allows me to do so .. . Answer : Up until now you cannot sort custom objects . You can do key based sorting but not of custom objects like the struct you mentioned . There are a couple of other open CUDA based algorithms available for doing this but that too requires some modification etc to make them work for you . Comment : That is not correct . There are versions of all the basic thrust sorting algorithms which take a functor modelled on the STL strict weak ordering binary predicate .

Thrust deliberately abstracts all of the underlying CUDA API calls away sacrificing some performance for ease of use and consistancy keep in mind that thrust has backends other than CUDA . If you want that level of flexbility you will need to try another library CUB for example . In later version it has become possible to set a stream of choice .

Answer : The traditional way to do this is to wrap the device pointer into a thrust : : device ptr and pass that to thrust algorithms . The tag based template model in Thrust will ensure that a device execution results because of the type of the input sequence supplied in the call . From Thrust 1.7 onwards the concept of execution policies have been introduced . This removes the need for explicit wrapping of the device address using device ptr .

As I have mentioned to talonmies I have my own implementation of expression-templates in CUDA and I would like to figure out how faster it is as compared to a standard implementation involving temporaries . Therefore I was planning to use matrix operations with pure thrust . My concern is that if I use Newton as you suggest then I would not see the effect of the creation of temporaries . What do you think about Comment : There are no temporaries created in the D A B + 3.f sin C expression . The assignment should result in a single kernel launch . Comment : Yes of course . But in my test now I do want the creation of temporaries to understand how much do I gain by expression templates.. . Comment : It sounds like you re asking how to implement that expression as inefficiently as possible : I suppose you could create functions such as operator+ which take device vector float parameters and return device vector float as a value . The implementation of such functions would just use thrust : : transform . Comment : In some sense yes : - I verified that evaluating expressions by my metaprogramming implementation takes the same time as by hand-written kernels so I m happy . I wanted then to compare such performance with that of an already available library and I thought about thrust .

Answer : I can think of 2 possibilities one of which is suggested already by @JaredHoberock . I don t know of a general methodology to fuse for-loop iterations in thrust but the second method is the more general approach . My guess is that the first method would be the faster of the two approaches in this case . 1 . Use a vectorized sort . If the regions to be sorted by your nested for-loops are non-overlapping you can do a vectorized sort using 2 back-to-back stable-sort operations as discussed here https : groups.google.com forum topic thrust-users BoLsxO6b4FY . 2 . Thrust v1.8 available with CUDA 7 RC or via direct download from the thrust github repository https : github.com thrust thrust includes support for nesting thrust algorithms https : github.com thrust thrust blob master CHANGELOG by including a thrust algorithm call within a custom functor passed to another thrust algorithm .

To test with dynamic parallelism change the compile switches from -arch sm 20 to -arch sm 35 -rdc true -lcudadevrt .. . 3 . This code requires CUDA 7 RC . I used Fedora 20 . 4 . The nested sort method also will allocate from the device side therefore we must substantially increase the device allocation heap using cudaDeviceSetLimit . 5 . If you are using dynamic parallelism and depending on the type of GPU you are running on the amount of memory reserved with cudaDeviceSetLimit may need to be increased perhaps by an additional factor of 8 .

My data was unsigned and the 16 most significant bits of my data were all zero . So I just put the row-number in the 16 msb and sorted it will thrust sort .", "Question : I am a newbie to Thrust . I see that all Thrust presentations and examples only show host code . I would like to know if I can pass a device vector to my own kernel How If yes what are the operations permitted on it inside kernel device code .. . Answer : This is an update to my previous answer . Starting from Thrust 1.8.1 CUDA Thrust primitives can be combined with the thrust : : device execution policy to run in parallel within a single CUDA thread exploiting CUDA dynamic parallelism . Below an example is reported . The above example performs reductions of the rows of a matrix in the same sense as Reduce matrix rows with CUDA http : stackoverflow.com questions 17862078 reduce-matrix-rows-with-cuda but it is done differently from the above post namely by calling CUDA Thrust primitives directly from user written kernels . Also the above example serves to compare the performance of the same operations when done with two execution policies namely thrust : : seq and thrust : : device . Below some graphs showing the difference in performance . Timings http : i.stack.imgur.com Vzc3L.jpg .. . .. . Speedups http : i.stack.imgur.com ajYbj.jpg .. . .. . The performance has been evaluated on a Kepler K20c and on a Maxwell GeForce GTX 850M .", "Question : I met some problems When using functions in thrust library I am not sure if I should add cudaDeviceSynchronize manually before it . For example .. . .. . Since kernel 1 is non-blocking host will execute the next statement . The problem is I am not sure if the thrust : : max element is blocking . If it is blocking then it works well otherwise will host skip it and execute the printf statement Thanks .. . Answer : Your code is broken in at least 2 ways . 1 . it is presumably a device pointer : .. . .. . kernel 1 blocks threads it .. . .. . .. . .. . it is not allowed to use a raw device pointer as an argument to a thrust algorithm : .. . .. . dt thrust : : max element it it + 10 .. . .. . .. . .. . unless you wrap that pointer in a thrust : : device ptr or else use the thrust : : device execution policy explicitly as an argument to the algorithm . Without any of these clues thrust will dispatch the host code path which will probably seg fault as discussed in the thrust quick start guide https : github.com thrust thrust wiki Quick-Start-Guide . 2 . If you fixed the above item using either thrust : : device ptr or thrust : : device then thrust : : max element will return an iterator https : thrust.github.io doc group extrema.html of a type consistent with the iterators passed to it . If you pass a thrust : : device ptr it will return a thrust : : device ptr . If you use thrust : : device with your raw pointer it will return a raw pointer . In either case it is illegal to dereference such in host code : .. . .. . dt thrust : : max element it it + 10 .. . .. . .. . .. . again I would expect such usage to seg fault . Regarding asynchrony it is safe to assume that all thrust algorithms that return a scalar quantity stored in stack variable are synchronous . That means the CPU thread will not proceed beyond the thrust call until the stack variable has been populated with the correct value .. . .. . Regarding GPU activity in general unless you use streams all GPU activity is issued to the same default stream . This means that all CUDA activity will be executed in-order and a given CUDA operation will not begin until the preceding CUDA activity is complete . Therefore even though your kernel launch is asynchronous and the CPU thread will proceed onto the thrust : : max element call any CUDA activity spawned from that call will not begin executing until the previous kernel launch is complete . Therefor any changes made to the data referenced by it by kernel 1 should be finished and completely valid before any CUDA processing in thrust : : max element begins . And as we ve seen thrust : : max element itself will insert synchronization . So once you fix the defects in your code there should not be any requirement to insert additional synchronization anywhere .

I have essentially taken functional code an put it into a functor that thrust : : for each can call using cuda streams . However if I define the functor using .. . .. .

It specifically quotes problems with the thrust : : device malloc allocator . If I define the functor as strictly a host functor these errors all go away however when I use the profiler it becomes evident that only 0.01 of the device is being used leading me to believe for each is not actually launching the thrust code in the functor . EDIT below is some code that compiles and shows this error .. . .. . Is it possible that thrust : : for each cannot call host functors Are some thrust calls innately connected to the host behind the scenes The only potential workaround I can see is creating a host device fucntor that has separate host and device defined code within it . It is also possible that I have missed something while researching this subject . Any advice would be greatly appreciated . Comment : You many want to create a MCVE code to reproduce your problem . stackoverflow.com help mcve http : stackoverflow.com help mcve .. . Answer : Thrust provides a host and a device path for all its algorithms but algorithms can only be launched from the host . At compile-time Thrust looks at the types of the iterators to determine which path to build . If it builds a device path then the same restrictions apply as for regular CUDA code one of which is that device code cannot call functions on the host . So a statement like thrust : : sort launches an algorithm and can only exist in host code . At compile-time the iterators passed to sort are examined and the Thrust templates are used for building either a host or a device version of sort that handles your particular types . If a device version is built and it takes a functor it must also be possible to build a device version of the functor which means that the functor can t contain a Thrust statement that launches a new algorithm . At runtime the device version of a statement like thrust : : sort will launch one or more CUDA kernels so what you might want to look into is Thrust s ability to combine separate algorithms into the same kernel which Thrust calls kernel fusion . There are a couple of ways to do this one of which is to use a transform iterator . See the Thrust docs for details . Comment : Thrust algorithms can be launched from device code . This answer is incorrect . OP has already asked several questions demonstrating that thrust algorithms can be launched from device code . Comment : I can clearly see that some can be launched from device code but it seems like some cannot . Is it just that some cannot at least in the form I m using specifically transforms and device vector allocations Are these set up differently in the library I tried to send the thrust : : device and also the thrust : : seq flag and it still threw a bunch of errors and did not work . Comment : A device vector is not an algorithm . You may want to read the thrust quick start guide . thrust : : device vector which is a container not an algorithm cannot be used in device code as the other answer already indicated to you . And no thrust : : for each or any algorithm cannot use a host only functor if the algorithm is working with device data . Comment : Oh I see . This makes much more sense now . Also when the containers are properly passed in the errors for the thrust : : transform also goes away . So this solves my problem . Thank you .", "Question : I would like to copy memory from the host to the device using thrust as in .. . .. . using CUDA streams analogously to how you would copy memory from the device to the device using streams : .. . .. . The problem is that I can t set the execution policy to CUDA to specify the stream when copying from the host to the device because in that case thrust would assume that both vectors are stored on the device . Is there a way to get around this problem I m using the latest thrust version from github it says 1.8 in the version.h file . Comment : The announcement I read https : groups.google.com forum topic thrust-users i6pxQ9jPZFU made it sound like streams were implemented for underlying kernel calls not necessarily across-the-board in thrust . If you did use streams for copying from host vector to device vector it s likely that you would want to use a pinned allocator http : thrust.github.io doc classthrust 1 1system 1 1cuda 1 1experimental 1 1pinned allocator.html on the host . I believe therefore that what you re asking for could be accomplished with thrust vectors and cudaMemcpyAsync . Comment : Yes you should use cudaMemcpyAsync for this directly as Robert suggests . Comment : Af of today May 2016 I find the first entry in the documentation here : thrust.github.io doc http : thrust.github.io doc group copying.html ga3e43fb8472db501412452fa27b931ee2 really disturbing . It says that we can write thrust : : copy thrust : : cuda : : par.on cudaStream HostPtr HostPtr+size DevicePtr as a valid syntax without getting your copy issued asynchronously to the particular stream you pass in parameter.. . .. . Answer : As indicated in the comments I don t think this will be possible directly with thrust : : copy . However we can use cudaMemcpyAsync in a thrust application to achieve the goal of asynchronous copies and overlap of copy with compute . Here is a worked example : .. . .. . For my test case I used RHEL5.5 Quadro5000 and cuda 6.5RC . This example is designed to have thrust create very small kernels only a single threadblock as long as KSIZE is small say 32 or 64 so that the kernels that thrust creates from thrust : : for each are able to run concurrently . When I profile this code I see : .. . .. . nvvp output for thrust streams application http : i.stack.imgur.com RoGmb.png .. . .. . This indicates that we are achieving proper overlap both between thrust kernels and between copy operations and thrust kernels as well as asynchronous data copying at the completion of the kernels . Note that the cudaDeviceSynchronize operation fills the timeline indicating that all the async operations data copying thrust functions were issued asynchronously and control returned to the host thread before any of the operations were underway . All of this is expected proper behavior for full concurrency between host GPU and data copying operations . Comment : is the use pf pinned allocator necessary to make cudaMemcpyAsync work correctly on a thrust : : host vector What would happen if I used a standard thrust : : host vector Comment : Standard host vector uses an unpinned i.e . not page-locked allocator . That means that when you try to do a cudaMemcpyAsync the operation will not be asynchronous . And if you are attempting to overlap that operation with something else it will not overlap .

Answer : These libraries especially thrust try to be as generic as possible and optimization often requires specialization : For example a specialization of an algorithm can use shared-memory for fundamental types like int or float but the generic version can t . It happens that for a particular situation a specialization is missing It s a good idea to use these well tested generic libraries as much as possible but sometimes for some performance critical sections your own implementation is an option to consider . In your situation you want many scans in parallel-for different rows . A good implementation would not run the scan separately for different rows : It would have the same kernel call running simultaneously for all elements of all the rows . Depending on its index a thread can know which row it s processing and will ignore all data out of the row . Such specialization requires a functor that returns an absorbing value that prevent mixing rows . Still your own careful implementation would be likely way faster .", "Question : I am a newbie to Thrust . I see that all Thrust presentations and examples only show host code .

Perhaps you should read the thrust quick start guide https : github.com thrust thrust wiki Quick-Start-Guide which discusses dispatch of thrust algorithms . Comment : @havogt if you want to provide an answer I would upvote . .. . Answer : Probably the main problem is context creation time : the first CUDA call will initialize the CUDA context which takes some time see here http : stackoverflow.com questions 10415204 how-to-create-a-cuda-context . Therefore you should start measuring time only after the first CUDA call . In general you can only expect speed-up with GPU code compared to CPU code if the degree of parallelism is high enough . The vector size of 10 as in the example code is definitely too small to achieve speed-up . With a vector size 10000 you can expect to fully utilize a modern GPU . You should also think about measuring only the time for sorting without the copy d vec h vec since often you will work with the device vector in the next step . Then you can consider the copy operation as a one time setup cost . However if sorting is the only operation on device it is of course reasonable to include the memcopy in the measurement .", "Question : Just a couple facts for setup : .. . .. .

Then when you d like to use an algorithm with your custom allocator you point Thrust at your custom backend when you call the algorithm . Note that this feature requires Thrust 1.6 or better . Comment : Thank you . That example does make sense but I have thrust 1.4 so it doesn t work for me . Is there a way to ensure that the thrust internals are using the proper allocator in older versions of thrust Comment : I m not sure what you mean by proper allocator . Thrust versions older than 1.6 can t customize temporary allocation . Comment : Yeah I don t either . I didn t have a full understanding how thrust allocates when you pass a device vector with a custom allocator to a thrust function . Playing around the with allocator example above answered it for me . Thanks again ." ] }	[ "yes-answer-long", "yes-answer-short" ]	stl	UNK_RELATION

Thank you . .. . Answer : One easy way is to use the PGM format itself in P5 binary mode . See PGM format http : netpbm.sourceforge.net doc pgm.html format from the Netpbm documentation . Set maxVal to 255 to use the full 8 bit range . This is probably the most common format for PGM as it is extremely easy and fast to both read and write .", "Question : This question is challenging to get more understanding on Image Processing using pure C .

Answer : And.. . what s the question Your code looks almost fine for reading binary PGM P5 it s just missing newline check for each pixel data row according to wikipedia article both ASCII and binary format have newlines at the end of each pixel data row . Some comments : .. . .. . Don t hardcode the width and height you should use information from the header instead .. .

The file could have line comments consider that Comment : Well when I create histogram reading the color variations I could not get any rational result . I will provide my PGM file for testing . BTW My title is my question . Don t you read it : Comment : An idea : try converting it to ASCII format P2 and view it that should check whether you read it correctly or not Comment : @exodream : the title might be a question but you seem to have posted a solution .

Can anyone see a bug", "Question : I m here to ask you a little help . I d like to write a C code that reads a PGM file P2 not binary and I have found many ways to do it on the Web . The problem is that every time I try to read some PGM images I have as examples on my PC I m not even able to read the header properly because it never recognizes the right P2 PGM format . I always get errors like : not valid pgm file-type or format unsupported . Here s the last code I m trying : Comment : Perhaps your PGM is not correct . It should be a simple ASCII file so open it with a code editor of choice and verify against the specifications http : netpbm.sourceforge.net doc pgm.html . Comment : Note that they say you shouldn t cast the result-of malloc in C http : stackoverflow.com questions 605845 do-i-cast-the-result-of-malloc . Comment : I opened every pgm image I have and all seems to be right . .. . Answer : It seems that there are libraries that can do this : libnetpbm from netpbm http : netpbm.sourceforge.net or PGMA IO https : people.sc.fsu.edu jburkardt c src pgma io pgma io.html . If you cannot use an external library for some reason a look at the source code may help you to figure out how the header is read . By the way have you already had a look at the answer to this question : how-to-read-a-pgm-image-file-in-a-2d-double-array-in-c http : stackoverflow.com questions 6085390 how-to-read-a-pgm-image-file-in-a-2d-double-array-in-c rq 1 Comment : Yes I did . Anyway thank you very much the libraries you suggested me were very useful", "Question : In PHP a simple read and write file can be done by using fread and fwrite . The unpack and pack operator are used to extract binary information . The question is how can I read and write PGM P5 image in PHP without using any additional PHP extension library Comment : You can read the specs http : netpbm.sourceforge.net doc pgm.html for the PGM format and use the functions you listed . This is a Q A site not a job site . If you have a specific problem we d be glad to help .

Answer : According to the spec : Portable Gray Map http : netpbm.sourceforge.net doc pgm.html .. . .. . This looks pretty simple . You don t even need pack unpack as sscanf should cope with most of the ASCII to integer translation . This C program http : fossies.org unix misc netpbm-10.35.83.tgz dox ppmtobmp 8c source.html which converts PGM to BMP may give you a few pointers . Comment : The P5 format is not purely ASCII . Your understanding about PGM is about P2 not P5 .", "Question : This is a part of my function for reading a PGM file byte by byte . In this for after something like 2000 bytes every byte that it reads is 0 . Instead of reading the image like this enter image description here http : i.stack.imgur.com zGgvb.jpg .. . .. . I get it like this .. . .. . enter image description here http : i.stack.imgur.com MELJu.jpg .. . .. . How can i solve this Edit : this is the definition of the pgm : Comment : Why do you write pgm .foo instead of pgm- foo How is pgm- data defined and initialized Comment : this is how my teacher made his notes . I ve put the definition of pgm in the post . It is initialized as PGM pgm Comment : your teacher must have pretty good reasons for reading an image file in such an awful way one byte at a time and using fscanf . Tell him her to read at least one image line at a time e.g . using fread and avoid parsing the input. . it s a binary file after all Comment : PGM is half text half binary . The header with the height width and max are in ASCII with whitespace . The maxvalue must be followed by exactly one whitespace character usually a newline after which the rest of the file is binary . Comment : @user3629249 I don t think any of that is true . .. . Answer : If you are using Windows you need to make sure that you open the file in binary mode . Otherwise a byte which happens to have the value 26 0x1A will be interpreted as an end of file after which no further bytes will be read . Other modifications will also be made which will produce other problems . On any OS it is best to open binary files in binary mode but on Windows it is hugely important . It is also important to check the return-value of fscanf . Fscanf is an awful way of reading a binary file for what its worth . If your teacher told you to do that you might want to have a discussion with him about good programming practice .", "Question : As a homework assignment we are supposed to read in a .pgm file and then draw a square in by changing the pixel values and then output the new image . After I go through and change the pixels I print them all to a .txt as a way to check that they actually got added . The part I m having trouble with is writing the new file . I know it s supposed to be binary so after googling I think I should be using DataOutputStream but I could be wrong . After I write the file its size is 1.9MB where as the original is only 480KB so right off the bat I suspect something must be wrong . Any advice or tips for writing to .pgm files would be great When I try to open the new file i get an error message saying illegal image format and the original file opens properly . Comment : Did you read the Java Tutorial on Byte Streams http : docs.oracle.com javase tutorial essential io bytestreams.html Comment : @Obicere we are supposed to read in a .pgm file The question is if the original file is binary or ASCII . Comment : @Obicere The original file is a .pgm file Comment : @LutzHorn its P5 so that would be a binary file . And reading the Tutorial now Thanks Comment : @LutzHorn Im not sure how I could manipulate the values that way .. . Answer : I think you are somehow confusing the binary P5 and ASCII P2 modes of the PGM format . The ASCII version has spaces between each pixel and optional line feeds like you have in your code . For the binary format you should just write the pixel values as bytes as you have max value 250 . No spaces or line feeds . I don t write the code for you as this is an assignment but you are almost there so I m sure you ll make it : - .. . .. . PS : Also carefully read the documentation on DataOuputStream.writeUTF .. . : .. . .. . First two bytes are written to the output stream as-if by the writeShort method giving the number of bytes to follow . Are you sure this is what you want Keep in mind that the PGM format headers are all ASCII so there s really no need to use UTF here .", "Question : I want to read pgm file . I kept image content in byte array . When I accessed pixels I see that some values are negative . So I applied 0xFF each byte . I hope it is ok but when I write to file it isn t same as original image . How can i read and write pgm p5 file .. . Answer : Keep in mind that the P5 format is binary . You are using a Writer and cast the value to-char . This is good for text but not for binary-data . Instead use an OutputStream and write the value in i directly to the stream . .. . .. . PS : If you don t feel like implementing the PGM format yourself I have created an ImageIO plugin for the NetPBM formats PNM http : haraldk.github.io TwelveMonkeys netpbm-portable-any-map-pnm you could use .

PGM files are binary you should use rb in the fopen in case you ever run this on Windows where binary vs . text are different .. . your histogram print function is missing the last pixel 255 is a valid pixel value .. . not sure why your histogram array goes to 64K are you planning to support 16-bit PGMs as well you should have error-handling to avoid crashes or other unexpected behavior .. . .. .

I m confused how profiles in slick-2.0 are intended to use . .. . Answer : type TableElementType is abstract inside of class AbstractTable A . Scala doesn t know about any relationship between A and TableElementType . class Table on the other hand defines final type TableElementType A which tells Scala about this relationship and apparently Scala is smart enough to use the final annotation to know that the relationanship even holds for a subtype T : Table A eventhough Table A is not co-variant in A .

Answer : I think you need to read up in implicit-conversion and implicit parameters in Scala . There are online Scala books available . When you get an error message about a missing implicit it either means you ran into a failing type-check provided by a library preventing you from doing something wrong but that s not the case here . Or you simply forgot to make the implicit available . There are two ways to make an implicit available . Either import it into the scope where you get the error message . Or basically defer the lookup to the callsite of your method . Not sure which one is the right one for play . You either need to import the implicit Application from play or you need turn val dao into a method and request an implicit application in an implicit argument list def dao implicit app : Application .. . .

Answer : Also have the same problem for the 22 columns limitation the test case https : github.com slick slick blob 2.1 slick-testkit src main scala com typesafe slick testkit tests JdbcMapperTest.scala L129-141 helps very much . Not sure why the example code not working for you the following code works fine for me Comment : thanks it seems you are right it works fine . It s just so easy to make a typo when you have very large tuples I think I had a problem with type-inference and maybe a typo so I decided to go step by step providing types explicitly at each step and now it works", "Question : I ve started using the Slick framework and the Code Generator that it s recommended to use .

Comment : This looks like an error in the compiler and involving IDEA . try to compile in the terminal with sbt . Comment : Tried it didn t worked too : .. . Answer : This is to do with a Scala limit of 22 things in a Tuple . There s more information on it over here https : stackoverflow.com questions 4152223 why-are-scala-functions-limited-to-22-parameters on why this is the case . 22 columns in a database-table is rather a lot though so I would suggest if it was possible to split that up into multiple joined tables that would be a way around the issue . Or indeed wait until Typesafe fix the issue in a future version of Scala . If indeed that ever happens .

Answer : Maybe you could create a TypeMapper for your enum type : .. . .. . .. . implicit val LoginStatusTypeMapper MappedTypeMapper.base LoginStatus.Value Int .. . conversion from LoginStatus to int .. . .. . status status.id .. . .. . conversion back from int to enum .. . .. . id LoginStatus id .. . .. . .. . .. . .. . then you need to reference your column as : .. . .. . columnLoginStatus.Value .. . .. . This way it will be transformed back to your enum when you load data from the database .

I see that one of the ways to get around the 22 column limit for tables in Slick is to use nested tuples . I can t figure out how to do that despite finding this partial code on GitHub https : github.com slick slick commit 7f8668e49da34cf0cb52ac21a6f5b46d0b0fdb47 .

Comment : This related question has lots of useful information : stackoverflow.com questions 13906684 http : stackoverflow.com questions 13906684 scala-slick-method-i-can-not-understand-so-far .. . Answer : The test code you linked to is outdated . If you don t use mappings for your tables it s straight-forward : The type of corresponds to the return-type you get when querying the table whether it is a single tuple an HList or nested tuples . Since Slick 2.1 this works for all operations . In 2.0 it was not supported for the projection so you had to define an alternate projection and override create . See here https : github.com slick slick blob 2.1 slick-testkit src main scala com typesafe slick testkit tests JdbcMapperTest.scala L312-337 for an HList example . If you want to map the projection to a custom type you also use the operator as for a single tuple but you don t get the convenience of the tupled and unapply methods that are automatically generated for case classes so you have to write the two mapping functions from the unmapped to the mapped type and back manually as shown here https : github.com slick slick blob 2.1 slick-testkit src main scala com typesafe slick testkit tests JdbcMapperTest.scala L129-141 . Note that Scala 2.11 does not improve this situation . While it allows case classes with more than 22 fields there are no corresponding Function types for arities 22 so you still can t use tupled and unapply . As an alternative to writing these functions you can define a lifted type corresponding to your mapped type as explained in the manual http : slick.typesafe.com doc 2.1.0 userdefined.html monomorphic-case-classes . This is especially useful when you have nested case classes of 22 fields each for your mapped type . You only have to define separate mappings for each case class and they will automatically compose when you use them in a projection or any other place in a projection or query . Comment : I can t make this custom case class mapping based on the test to work . I ve opened a related question here : stackoverflow.com questions 28305023 http : stackoverflow.com questions 28305023 custom-mapping-to-nested-case-class-structure-in-slick-more-than-22-columns", "Question : I m trying to create a typesafe dynamic DSL for a Slick table but not sure how to achieve this .

Or reduce since you don t need a seeding value . buildFilter.reduce Comment : I read about dynamic filtering a couple of times in the last days on stackoverflow . Maybe it is worth documenting it . What do you think I could help . Comment : Yes it is a feature that everybody building an UI with form filters need . I m kind of surprised this is not a main feature provided by Slick for querying as it s so commun . Hibernate and JPA have the Criteria API for years Comment : I don t quite understand . .filter in combination with .reduce or .fold is an excellent way to do this . What else do you need Slick s composability makes it happen which is a main feature of Slick . Comment : Documenting it is a good idea .

I can t understand how they just compile once and the advantage behind their use Comment : Is not that they execute once . It s compiled once . Comment : Why would they need to be compiled more than once And are you familiar with prepared statements Comment : @perdrofurla yep edited.. . can you give me a clear explanation Comment : Not really I only have a vague idea . But I summoned the gurus they might be able to answer effectively . Comment : actually I am trying to understand a slick example slick.typesafe.com doc 2.1.0 queries.html compiled-queries http : slick.typesafe.com doc 2.1.0 queries.html compiled-queries and as a beginner i can not understand the advantage behind using compiled queries . .. . Answer : The advantage is easy to explain : Query compilation takes time both in Slick and in the database server . If you execute the same query many times it s faster to compile only once . Slick needs to compile an AST with collection operations into a SQL statement . Actually without compiled queries you always have to build the AST first but compared to the compilation times this is extremely fast . The database server has to build an execution plan for a query . This means parsing the query translating it to native database operations and finding optimizations based on the data layout e.g . which index to use . This part can be avoided even if you don t use compiled queries in Slick simply by using bind variables so that you always get the same SQL code for different sets of parameters . A database server keeps a cache of recently used compiled executions plans so as long as the SQL statement is identical the execution plan is only a hash lookup away and doesn t need to be computed again . Slick relies on this kind of caching . There is no direct communication from Slick to the database server to reuse an old query . As to how they are implemented there is some additional complexity for dealing with streaming non-streaming and compiled applied ad-hoc queries in the same way but the interesting entry-point is in Compiled : .. . .. . This gives you an implicit Compilable object for every Function . Similar methods for arities 2 to 22 are auto-generated . Because the individual parameters only need a Shape they can also be nested tuples HLists or any custom type . We still provide abstractions for all function arities because it s syntactically more convenient to write say a Function10 than a Function1 that takes a Tuple10 as its argument . There s a method in Shape that only exists to support compiled functions : .. . .. . The packed representation built by this method can produce an AST containing QueryParameter nodes with the correct type . They are treated the same as other literals during compilation except that the actual values are not known . The extractor starts as identity at the top level and is refined to extract record elements as required . For example if you have a Tuple2 parameter the AST will end up with two QueryParameter nodes which know how to extract the first and second parameter of the tuple at a later point . This later point is when the compiled-query is applied . Executing such an AppliedCompiledFunction uses the pre-compiled SQL statement or compiles it on the fly when you use it for the first time and fills in the statement parameters by threading the argument value through the extractors . Comment : thanks a lot for your answer . Now I understand the utility of the use of compiled queries but I can t try them in an example .can you give me a concrete example . thanks Comment : You can find plenty of examples here : github.com slick slick blob master slick-testkit src main scala https : github.com slick slick blob master slick-testkit src main scala com typesafe slick testkit tests TemplateTest.scala", "Question : I m trying to create a typesafe dynamic DSL for a Slick table but not sure how to achieve this .

Answer : I m answering my own question with what I ve finally built . Let s define a simple case class and row mapper .. . .. . Notion of predicate in Slick .. . .. . I assume that the notion of predicate is what can be put inside TableQuery.filter . But this type is rather complex as it is a function that takes a Table and returns a type that has an implicit CanBeQueryCondition .. . .. . Unfornunately for me there are 3 different types that have a CanBeQueryCondition and putting them in a list to be folded into a single predicate seems not easy ie filter is easy to apply but the and operators are hard to apply as far as I ve tried . But fortunately it seems we can convert easily a Boolean to a Colunm Boolean to a Column Option Boolean with the . extension method . So let s define our predicate type : .. . .. . Folding a list of predicates ie using conjunctions disjunctions ie composing AND and OR clauses .. . .. . Now we only have one type so we can easily fold a list of predicates into a single .. . .. . .. . .. . The dynamic filtering case class .. . .. . From these predicate primitives we can start creating our dynamic composable and typesafe query DSL based on a case class . Notice the usage of . for the companyScopeId field which permits to fit a non-optional column to our definition of a Slick predicate .. . .. . Using the DSL .. . .. . Conclusion .. . .. . This is far from being perfect but is a first draft and at least can give you some inspiration : I would like Slick to make it easier to build such things that are very common in other query DSL like Hibernate JPA Criteria API Comment : I already see you creating a new repository on github named slick-criteria good work Sebastien Comment : thanks : yes that could be a nice idea even if the project would not contain much things Comment : Wow this is gold Thanks for sharing" ] }	[ "yes-answer-long", "yes-answer-short" ]	scala	UNK_RELATION

Why TouchJSON can t just replace them with real string via UTF8 How should I deal with the results if I want to store them as NSStrings and use them in UILabel Thanks .. . Answer : The leading u should not be a part of the string but rather an identifier . If you load an NSString from parsed NSDictionary it should ve ignored the leading u .

Any help would be appreciated . Thanks Kurtis .. . Answer : TouchJSON does not handle any transfer of data via http https or any other protocol .

Answer : You can create a mutable dictionary from a dictionary like this . assuming your json parsed dictionary was named jsonDictionary .. . .. . Hope that solves it for you . Comment : Hi Peter and NWCoder . My overall NSDictionary I cast to mutable when parsing is complete . The problem is then the user and object dictionaries inside the overall dictionary are still imutable : For now I go through each of my json dictionaries make the outer dict mutable pull out the inner dicts by key make a mutable copy of them delete the old dict and reinsert the new mutable one - terrible workflow especially when objects change server-side .

Answer : You re missing some fundamentals here . SOAP is XML based . JSON is an alternative markup to XML that s more compact . Making a REST call simply means you are requesting a resource .

If you are calling out to a SOAP web service however it is not going to return JSON but rather XML that needs to be made into an object using a SOAP library .

So my questions are I have both NSNumbers and NSStrings in the JSON should I traverse the result from TouchJSON s deserialize method and test all values and how would I do so .. . .. . I can t simulated what would happen if an NSNumber value was empty how would I test for this Will the NSNumber value be nil in that case instead of null .. . Answer : I was using the SBJSON library and came up against the same problem . My solution would apply to your case too : I changed the library so that it handled missing values setting them to + NSNull null in the collection it returned . That makes your client code a little warty because you have to handle the cases where you might get an NSNull instead of an NSString . But this is just a more obvious version of the wart where you have to decide whether @ meant an empty string or an unset value . Comment : Hi Graham thanks for the suggestion . I wasn t up for rewriting the scanner part of the TouchJSON so instead I loop the data returned and replace the empty strings with @ and the empty numbers with 0 . I get to do this because I only deal with Strings and Numbers and my data goes directly into views that are fine with @ .

Any clues on what is going on I m completely lost on what to do as there isn t much documentation available for TouchJSON and much less usage examples . .. . Answer : I m the author of TouchJSON . Your outermost object should be a dictionary and NOT an array . Anything other than a dictionary is not legal . If you have to have an array as the outermost object then use the method which is technically deprecated but isn t going any where soon .. . .. . See : http : www.json.com json-schema-proposal for more information abotu what is and is not legal JSON . Comment : I appreciate your response to my question first of all . I was surprised to hear that the outermost object cannot be an array as I have been doing this type of JSON result for a long time now and most times things work out just fine with other libraries . Continuing on a separate comment.. . Comment : According to the JSON RFC created by Douglas Crockford himself ietf.org rfc rfc4627.txt http : www.ietf.org rfc rfc4627.txt arrays as outermost objects are perfectly valid . See Page 7 8 for an actual example in there . Comment : See robubu.com p 24 http : robubu.com p 24 for more info . Top level arrays ought to be avoided . Regardless TouchJSON can process them - see the API i listed above . Comment : Well can we at least agree that it is perfectly legal to have arrays as the outermost object What that post is describing is a browser javascript interpreter vulnerability . Arrays are perfectly legal but maybe just not officially supported by your library . Comment : In most languages it is also perfectly legal to do something like ++i-- that does not mean it is good practice .

However many people use bloated unmanageable frameworks like CSLA because they are trying to reduce the amount of coding and maintenance they actually have to do . It s a fools errand . My point was simply that if a person s objective is to use a framework that will allow quick implementation of an application entity-framework now that linq-to-sql is dead or nhibernate would be better solutions . I ve worked with CSLA and while it can be implemented rather quickly it is a freaking maintenance nightmare . Comment : I know this was a long time ago but I would also like to add that this answer is very misleading . CSLA is not about the data but the business its rules and its validations . I have worked with CSLA and would say that initially I found it a bit bloated however when I got to know its depths I found it to be an extremely good framework that provided structure for developers and strength to applications built with it .

Answer : CSLA is used in our company world-wide . I personally have used it to develop web sites web-services rich client apps etc . In one particular application using CSLA we ve deployed to Asia Europe Sites in the U.S . and sites at sea on ships . CSLA insulates developers from the gotcha s of the .Net framework and the ever changing architectural topology at Microsoft .

I don t need a road block between my code and the .NET framework which is what this framework felt like to me . I had a limited option of list objects while I just had to ignore the rich list objects in the .NET framework . Ii is totally ridiculous that we had these read-only lists and then non read-only lists . So if I had to add an item to the list I had to recreate the entire list...are you serious Then csla wants to manage my object state which is fine but nothing is really exposed . Sometimes I want to change an object state manually instead of fetching it again which seems like what csla wants me to do . I basically end up creating many properties to expose options csla didn t think I should have direct access to . Why can t I just instantiate an object We end up creating static-methods which instantiates an object and passes it back...are you kidding me Check the framework source code and it looks to heavy on the reflection code to me . Reasons to use csla : .. . .. . the straight .net framework is too powerful for you . your developers are not seasoned and can t grasp the concept of patterns then csla will pretty much have everyone on the same page . 1 .

How may people are using CSLA 2 . What are the pros and cons 3 . Does CSLA really not fit in with TDD 4 . What are my alternatives 5 . If you have stopped using it or decided against why .. . Answer : After reading all the answers I ve noticed that quite a few people have some misconceptions about CSLA . First CSLA is not an ORM . How can I say that so definitely Because Rockford Lhotka has stated it himself many times in interviews on the .NET Rocks and Hanselminutes podcasts . Look for any episode where Rocky was interviewed and he ll state it in no uncertain terms . I think this is the most critical fact for people to understand because almost all the misconceptions about CSLA flow from believing that it is an ORM or attempting to use it as one . As Brad Leach alluded in his answer CSLA objects model behavior although it may be more accurate to say that they model the behavior of data since data is integral to them . CSLA is not an ORM because it s completely agnostic about how you talk to your data store . You should use some kind of data-access-layer with CSLA perhaps even an ORM . I do . I now use Entity Framework which works beautifully . Now on to unit-testing . I ve never had any difficulty unit-testing my CSLA objects because I don t put my data-access code directly into my business-objects . Instead I use some variation of the repository pattern . The repository is consumed by CSLA not the other way around . By swapping in a fake repository for my unit tests and using the local data portal BOOM it s simple . Once Entity Framework allows the use of POCOs this will be even cleaner . All of this comes from realizing that CSLA is not an ORM . It might consume an ORM but it itself is not one . Cheers . UPDATE .. . .. . I thought I d make a few more comments . Some people have said that CSLA is verbose compared to things like LINQ to SQL and so on . But here we re comparing apples to oranges . LINQ to SQL is an ORM . It offers some things that CSLA does not and CSLA offers some things L2S does not like integrated validation and n -tier persistence through the various remote data portals . In fact I d say that last thing n -tier persistence trumps them all for me . If I want to use Entity Framework or LINQ to SQL over the net I have to put something like WCF in between and that multiplies the work and complexity enormously to the point where I think it is much more verbose than CSLA . Now I m a fan of WCF REST and SOA but use it where you really need it such as when you want to expose a service to third parties . For most line-of-business apps it isn t really needed and CSLA is a better choice . In fact with the latest version of CSLA Rocky provides a WCFDataPortal which I ve used . It works great . I m a fan of SOLID http : butunclebob.com ArticleS.UncleBob.PrinciplesOfOod TDD and other modern software development principles and use them wherever practical . But I think the benefits of CSLA outweigh some of the objections of those orthodoxies and in any case I ve managed to make CSLA work quite well and easily with TDD so that s not an issue .

For clsa the same reasons apply . 1.1 . Is like the stone age and you have no support . Upgrading without using redesign should not so be hard .

This might be a novice question but I didn t see a clear explanation elsewhere . Can someone please help me in understanding what is the difference between .. . .. . and .. . Answer : CSLA implements a powerful new way of implementing properties where you don t need to declare a field to store the property s value . The field values are managed by CSLA .NET and so are called managed fields . In the future some advanced features of CSLA .NET may be unavailable unless you use managed fields . Syntax : .. . .. . CSLA also supports a different syntax where you use private fields to store the values . This technique is faster than using managed fields but requires that you declare and maintain your own fields .

Answer : We use CSLA extensively . There are several benefits first I believe that every line of business developer should read Rocky Lhotka s book on Business Objects programming . I ve personally found it to be in my top 3 best programming books ever . CSLA is a framework based on this book and using it gives your project access to very high level functionality like n-level undo validation rules and scalability architecture while providing the details for you . Notice I said providing and not hiding . I ve found that the best part of CSLA is that is makes you understand how all of these things are implemented down to the source code without making you reproduce them yourself . You can choose to use as many or few features as you need but I ve found that by staying true to the design-patterns of the framework it really keeps you out of trouble . --Byron Comment : Ditto on the benefits of reading the book . Last I read the new .NET 3.x version of the book was not to include the same ground-up tour through the source code that the .NET 2.x version had .

I ve been using it for several years . However now that WCF and REST are out there they have removed a large part of the reason that one would want to use CSLA . Unless you really need strong clean dirty databinding support for your UI and or n-level undo for changes to your objects I would seriously look at WCF and REST as that is a more open standard for data-access-layer abstraction .

How may people are using CSLA 2 . What are the pros and cons 3 . Does CSLA really not fit in with TDD 4 . What are my alternatives 5 . If you have stopped using it or decided against why .. . Answer : I ve been using CSLA since vb5 when it was more of a collection of patterns than it was a framework . With the introduction of.NET CSLA turned into a full-blown framework that came with a hefty learning curve . However the CSLA addresses many things that all business developers tend to write themselves at some point depending on project scope : validation logic authentication logic undo functionality dirty logic etc . All of these things you get for free out of the box in one nice framework . As others have stated being a framework it forces developers to write business logic in a similar fashion . It also forces you to provide a level of abstraction for your business logic so that not using a UI framework such as MVC MVP MVVM becomes not so important . In fact I would argue that the reason why so many of these UI patterns are so hyped up today in the Microsoft world is that people have been doing stuff incredibly wrong for so long ie . using DataGrids in your UI sprinkling your business logic everywhere . tisk tisk . Design your middle-tier business logic correctly from the start you can reuse your middle-tier in ANY UI . Win Form ASP.NET MVC WCF Service WPF Silverlight Windows Service ... . But aside from these the huge payoff for me has been it s built-in ability to scale . The CSLA uses a proxy-pattern that is configurable via your config file . This allows your business-objects to make remote calls from server to server without having to write one lick of code . Adding more users to your system No problem deploy your CSLA business-objects to a new application server make a config file entry change and BAM Instant scalability needs met . Compare this to using DTO s storing your business logic on the client whatever client that may be and having to write each of your own CRUD methods as service methods . YIKES Not saying this is a bad approach but I wouldn t want to do it . Not when there s a framework out there to essentially do it for me . I m going to reiterate what other folks have said in that CSLA is NOT an ORM . CSLA forces you to supply your business-objects with data . They do not care where you get your data . You can use an ORM to supply your business-objects with data . You can also use raw ADO.NET other services RESTFUl SOAP excel spreadsheets I can keep going here . As for your support for TDD I have never tried using that approach with CSLA either . I have taken the approach where I model my middle-tier ala business-objects using class and sequence diagrams most often allowing use-case screen and or process design to dictate . Perhaps a bit old school but UML has always served me very well in my design and development efforts . I ve successfully designed and developed very large and scalable applications still being used today . And until WCF RIA matures I ll be continuing to use CSLA. . .. . .. . with some work arounds", "Question : I d like to learn CSLA.NET quickly . What advice do you have Comment : you could always contact Rocky and pay his very large consulting fees . .. . Answer : I would highly recommend checking out our CSLA 3.8 templates http : code.google.com p codesmith downloads list . They come in both a VB.NET and a C flavor . We are currently working on a major release that adds SQL Stored Procedure Object Factory and Many-to-Many support . It is a great starting point because we have real world examples like the Microsoft PetShop Sample application that is completely generated both the business layers and data-access layers with unit tests to show you exactly how CSLA works . If you have any questions or run into issues we are here to help you understand and grow as a CSLA developer . Another great compliment to learning CSLA is purchasing the following book : Expert C 2008 Business Objects http : rads.stackoverflow.com amzn click 1430210192 .

Answer : Andy is quite right that the eBooks and Expert Busines Object books are a vital starting point . Additionally there is a worked example called ProjectTracker which is discussed in the books which gives examples of the various ways of doing things in CSLA such as the options for implementing connecting to the data-access-layer . The easiest way to install ProjectTracker is to download the full CSLA installer from here : http : www.cslanet.com Download.html .. . .. . The last time I installed that file version 4.5.30 the ProjectTracker project wasn t set up to run with Visual Studio 2013 so if you are new to CSLA and also running VS2013 this post I wrote on the CSLA forum may help you it describes how to get Project Tracker working in VS2013 : http : forums.lhotka.net forums t 12200.aspx .. . .. .

Answer : I m a PHP guy . When we started building comparatively large scale applications with PHP I started researching on lots of application frameworks and ORMs essentially in PHP world then in Java and .NET . The reason I also looked at Java and .NET frameworks was not to blindly use any PHP framework but first try to understand what is really going on and what kind of enterprise level architectures are there . Because I haven t used CSLA in a real world application I can t comment on its pros and cons but what i can say is Lhotka is one the rare thinkers -I m not saying just expert- in Software Architecture field . Although the name Domain Driven Design is coined by Eric Evans -by the way his book is also great and i humbly advise to read it- Lhotka was applying domain-driven-design for years . Having said that whatever you think about his framework benefit from his profound ideas in the field . You can find his talks on dotnetrocks.com archives.aspx and videos from dnrtv.com archives.aspx search for Lhotka . @Byron What are the other two books you liked", "Question : The main web application of my company is crying out for a nifty set of libraries to make it in some way maintainable and scalable and one of my colleagues has suggested CSLA .

Answer : I m new to CSLA but I understand the concepts and I already understand that it s not an ORM tool so quit beating that damn drum folks . There are features of CSLA I like but using them feels a bit like there is a magician behind the curtain . I guess if you don t mind not knowing about how it works then you can use the objects and they work fine . There is a large learning curve for beginners and I think it would benefit greatly by having 5-15 min . videos like Microsoft has for learning the fundamentals . Or how about releasing a companion book with the code instead of getting the code released and taking months to get the book out Just sayin Mr Lohtka.. . We started building our stuff before the book and I struggled the whole time . But like I said I m new to it . We used CSLA . We made our objects fit their mold then used 10 of what the framework offered . Object level undo Didn t use it . NTier flexibility Didn t use it . We ended up writing enough business rule code that I thought the only thing we were getting out of CSLA was complexity . Some long in the tooth developers that know the framework used it as their hammer because they had a nail that needed hitting . CSLA was in their belt and my guess is a lot of proponents of the framework see things from that perspective too . I guess our seasoned developers are happy because it all makes sense to them . I guess if your organization doesn t have newbie programmers and you guys get bored by writing efficient and simple POCO objects with well formed patterns then go for it . Use CSLA .", "Question : My one ASP.NET web site uses two different business object class libraries . There is a common framework DLL CSLA.dll between these two libraries . The problem is that one library wants to upgrade to CSLA v.4.0.1 and the other wants to remain at v.2.1.4 .

The assemblyBinding config element . http : msdn.microsoft.com en-us library twy1dw1e.aspx .. . .. . In your case the configuration should go in your web.config since the redirection is application-specific and doesn t apply to an entire version of the framework .", "Question : The main web application of my company is crying out for a nifty set of libraries to make it in some way maintainable and scalable and one of my colleagues has suggested CSLA .

How may people are using CSLA 2 . What are the pros and cons 3 . Does CSLA really not fit in with TDD 4 . What are my alternatives 5 . If you have stopped using it or decided against why .. . Answer : Yes I um we used it extensively to model our business-process logic that was primarily databound forms in a windows forms application . The application was a trading system . CSLA is designed to be at that layer just below the UI . If you think about your standard complex line-of-business application you may have a form with many fields many rules for those fields including cross-field validation rules you may invoke a modal-dialog to edit some child object you may want to be able to be able to cancel such dialogs and revert back to a previous state . CSLA supports this . It s cons are that it has a bit of a learning curve . The key thing to remember is to use CSLA to model how a user interacts with forms on some application . The most efficient way for me was to design the UI and understand it s flows behaviour and validation rules before building the CSLA objects . Don t have your CSLA objects drive UI design . We also found it very useful to be able to use CSLA business-objects server-side to validate objects sent from clients . We also had built-in mechanisms to perform validation asynchronously against web service i.e . checking the credit limit range of a counterparty against a master . CSLA enforces a strong seperation between your UI BusinessLogic and Persistance and we wrote a load of unit tests against them . It may not be strictly TDD because you are driving it from UI design that doesn t mean it isn t testable . The only real alternative is creating your own model business-objects but pretty soon you end up implementing features that CSLA offers out of the box INotifyPropertyChanged IDataErrorInfo PushState PopState etc .", "Question : I m currently researching and deciding on a code-coverage tool for my company and have so far tried NCover Bolt and Desktop DotCover and NCrunch . All tools I ve tried so far work well for measuring highlighting code-coverage in code called directly by unit tests but any code called through CSLA DataPortal Fetch for example is never detected as being covered . As much of our code base resides in these functions I m finding the tools to be next to useless for much of what I need tested and measured . My question then is how can I get code-coverage results for CSLA code Does anyone know of a tool that would work with these kinds of calls or certain options extensions I can use to get coverage results with the tools I m using The project is coded in C and I m using Visual Studio 2013 Professional CSLA 3.8 and .NET 4.0 . I have the latest versions of NCover Bolt and DotCover both on trial as well as the newest OpenCover that I could find . Thanks in advance Comment : I don t think you are going to find much due to CSLA being heavy on reflection which is your problem with the Fetch . That is one of my biggest pet peeves with CSLA . Comment : You want coverage on functions invoked by CSLA through reflection and can t get it Comment : I need coverage of my custom CSLA functions called after the internal CSLA reflection calls are made . That is when I call DataPortal.Fetch blah internal calls are made then my DataPortal Fetch blah function that I have in my business class no separate DAL is called . This second function isn t getting caught by code-coverage by any tool I ve tried thus far . Comment : I ve written unit tests for Csla objects and dotCover seems to figure out that the DataPortal Fetch is called . I am sure because it highlights the code . I ll point out that the unit tests always use the local dataportal . I m also running with R 8 but nCover on our build-server worked fine too . Did you change any of the default coverage options Comment : Is the CSLA code being executed in the same process as the rest of the code If you have a sample then I may be able to investigate further with OpenCover instrumentation no guarantees . .. . Answer : Unlike TyCobb s entirely outdated opinion current versions of CSLA don t invoke methods via reflection except on iOS and haven t since around 2007 . But the data portal does use dynamic invocation via expression-trees and that s probably the issue causing you trouble . One option in current versions of CSLA is that the data portal is now described by an interface so you can mock the data portal potentially creating a mock that does nothing but invoke your DP XYZ methods directly . Even that s tricky though unless you make them public and allow other code in your app to easily break encapsulation yuck . The problem is that you won t be able to call the methods without using reflection or rewriting the dynamic expression tree invocation code used inside CSLA.. . Though perhaps the code-coverage tools would see the code executing if it were run via reflection instead of via a runtime compiled expression Comment : Sadly I m using CSLA 3.8 so the interface might not be an option for me .", "Question : I have CSLA 1.x framework objects from an existing project that I m trying to use in a new .Net 4.0 project .

Like I said these objects are CSLA objects written in vb.net . I don t know where to look on this one . Is it an issue of .Net 4.0 trying to talk to CSLA 1.x or is it a web service issue as these objects never used web-services originally Does anyone have an idea about where I should look to figure out this issue Should I suggest converting to CSLA 2.x Any suggestions are appreciated .. . Answer : This is an XmlSerializer limitation if something looks like a list of data it will want to Add items to it via the Add method . If you have access to those objects consider adding such a method . I can t recall whether it wants Add object vs Add SomeType so try both . If you don t have control over those objects.. . it will be hard . It would be quicker to write a new DTO layer for the objects than to try to patch it somehow . Comment : Thank you for your answer.. . What does DTO stand for I do have control over those objects however they are also being used in another project which would mean I would have to include more people in this type of change . So your DTO option is intriguing.. .

When you Remove an item from the collection the item is removed from the active collection and is added to a DeletedList protected inside the collection . When you ask the data portal to Update your object graph your data-access code needs to remove items in the DeletedList and insert update items in the active collection . Versions of CSLA since around 2007 do this automatically by invoking the appropriate Child Insert Child Update and Child Delete methods in the child objects contained by your collection . In any case you can find detailed information about the data portal operations in the Using CSLA 4 book ." ] }	[ "yes-answer-long" ]	frameworks	UNK_RELATION

I also want stripes as shown here http : datatables.net examples styling hover.html but with my custom colors . I used cssStripes odd even but not working . : .. . .. . So I want to apply custom theme instead of basic themeoptions http : dandelion.github.io datatables docs ref configuration themeoptions themes . I have downloaded my custom theme from ThemeRoller http : jqueryui.com themeroller name PurpleTheme . How can I apply this to datatables I am loading themes from spring theme properties using spring themeresolver and themeinterceptor . Any help is invited . Thank you in advance.... . .. . Answer : I just made a test by downloading a theme from ThemeRoller http : jqueryui.com themeroller . Here follows the required steps to apply a custom theme using Dandelion Dandelion-Datatables v0.10.0 . 1 Download and install the jQueryUI-related assets .. . .. . Once you ve downloaded all assets from ThemeRoller place them inside your project . In my example I use the following standard Maven architecture : .. . .. . Warning : I had to update all image links in the CSS file to point them to my images folder . . images instead of images . 2 Prepare a new asset bundle .. . .. . Once all assets are here create a new bundle http : dandelion.github.io dandelion features asset-bundles introducing-asset-bundles.html called custom-theme.json in the src main resources dandelion folder . In this file you just need to reference your custom CSS . Don t forget to mark this bundle as dependent of the jqueryui one which is already activated when you use the theme jqueryui table attribute . 3 Create an extension for Dandelion-Datatables .. . .. . Currently the only way to use a custom theme option for the jqueryui theme is to create an extension . In order to alleviate the configuration JSP-side I suggest you to create an extension actually a theme that will activate both jQueryUI and your custom theme so that you don t need to use theme jqueryui any longer . 3.1 Create a class that extends AbstractExtension .. . .. . 3.2 Register your extension .. . .. . Then your extension must be detected by Dandelion-Datatables . To do so you must define the group .main.extension.package property in the configuration file . This property is actually a package where Dandelion-Datatables will scan for extensions . So I added a new datatables.properties file under the src main resources dandelion datatables folder which contains : .. . .. . 4 Activate the extension .. . .. . Once the ground prepared you can test your extension by activating it thanks to the ext table attribute . Just pass the name you have given above in the getName method of your extension . 5 Adapt the configuration .. . .. . It works well without export links . But as soon as you activate the export feature Dandelion-Datatables will update the sDom parameter with a new letter : E for Export therefore breaking the configuration previously set by the jQuery theme . So you just need to override this setting as follows : .. . .. . Another option would be to configure the sDom parameter directly in the above CustomJqueryTheme Java class . Finally if you want to update the odd even rows just use the cssStripes table attribute as follows : .. . .. . Just ensure : .. . .. . either to use something different than odd and even because Datatables use these classes .. . or if you still want to use odd and even make sure to override them with custom CSS rules . .. . .. . As you can see it s not very easy . : - .. . .. . But it should become a bit simpler in upcoming versions thanks to improvements in the extension mechanism . Note that I ll update this answer once this example will be available in the official Dandelion-Datatables sample applications .

Execute utility for each input line replacing one or more occurrences of replstr in up to replacements or 5 if no -R flag is specified arguments to utility with the entire line of input . The resulting arguments after replacement is done will not be allowed to grow beyond 255 bytes this is implemented by concatenating as much of the argument containing replstr as possible to the con-structed arguments to utility up to 255 bytes . The 255 byte limit does not apply to arguments to utility which do not contain replstr and furthermore no replacement will be done on utility itself . Implies -x . Edit 2 : Partial solution .

Turning it into a string responded with Fatal error : operator not supported for strings . However removing that variable all together would provide me with valid JSON readout . I assume this will suffice just fine . Thanks so much again for the response . Any chance you d be willing to say why that solution fixes it or perhaps a link explaining it Thanks again . Comment : what I did was to json encode an array of objects at once where as you were json encode EACH object and then combine the strings both way should work just that your step of combining the strings were incorrect .", "Question : I have a web service returning following json : .. . .. .

Comment : Are you trying to pretty-print the JSON or validate it jsonlint is a validator . To pretty-print you can do JSON.stringify JSON.parse .. . false 2 . Comment : Definitely pretty-print but it still hits the same error even with node --max-old-space-size 2000 prettyPrint.js . My entire script is : var fs require fs var f fs.readFileSync ugly.json o JSON.parse f p JSON.stringify o null 3 fs.writeFileSync p pretty.json . Any suggestions Comment : Have you thought about how big this JSON is going to be pretty-printed Is the 40MB mostly single long strings or is this a ton of nested objects I ask because it isn t necessarily impossible that it would be bigger than 2000MB when you factor in that you ll also be taking up a lot of RAM to store the parsed structure . Comment : It s lots and lots of nested objects . I managed to successfully stringify it using an indentation of t and it came out to about 72MB . The linecount is 1429654 . If I could just change that to space indentation instead of tab that would be fine too I guess . .. . Answer : jsonlint is based on Jison that s a parser-generator . It s simple to write but it s extremely slow . So just don t use that unless you really need some of it s features like sorting object keys . If you want to pretty-print JSON either use built-in - JSON.stringify object t or jju https : github.com rlidwka jju module - require jju .stringify object mode : json for more compact but still human-readable representation . 40MB will result to about 200-300MB of space which is definitely not that big .", "Question : I am using jQuery to get a list of Names as JSON string - .. . .. . .. . .. .
