I have a PostgreSQL v8.3 database that is heavily optimized for OLTP . I need to extract data from it on a semi real-time basis some-one is bound to ask what semi real-time means and the answer is as frequently as I reasonably can but I will be pragmatic as a benchmark lets say we are hoping for every 15min and feed it into a data-warehouse . How much data At peak times we are talking approx 80-100k rows per min hitting the OLTP side off-peak this will drop significantly to 15-20k . The most frequently updated rows are 64 bytes each but there are various tables etc so the data is quite diverse and can range up to 4000 bytes per row . The OLTP is active 24x5.5 . Best Solution .. . .. . From what I can piece together the most practical solution is as follows : .. . .. . Create a TRIGGER to write all DML activity to a rotating CSV log file .. . Perform whatever transformations are required .. . Use the native DW data pump tool to efficiently pump the transformed CSV into the DW .. . .. . Why this approach .. . .. . TRIGGERS allow selective tables to be targeted rather than being system wide + output is configurable i.e . into a CSV and are relatively easy to write and deploy . SLONY uses similar approach and overhead is acceptable .. . CSV easy and fast to transform .. . Easy to pump CSV into the DW .. . .. . Alternatives considered ... . .. . .. . Using native logging http : www.postgresql.org docs 8.3 static runtime-config-logging.html . Problem with this is it looked very verbose relative to what I needed and was a little trickier to parse and transform . However it could be faster as I presume there is less overhead compared to a TRIGGER . Certainly it would make the admin easier as it is system wide but again I don t need some of the tables some are used for persistent-storage of JMS messages which I do not want to log .. . Querying the data directly via an ETL tool such as Talend and pumping it into the DW .. . problem is the OLTP schema would need tweaked to support this and that has-many negative side-effects .. . Using a tweaked hacked SLONY - SLONY does a good job of logging and migrating changes to a slave so the conceptual framework is there but the proposed solution just seems easier and cleaner .. . Using the WAL .. . .. . Has anyone done this before Want to share your thoughts .. . Answer : Assuming that your tables of interest have or can be augmented with a unique indexed sequential key then you will get much much better value out of simply issuing SELECT .. . FROM table .. . WHERE key : last max key with output to a file where last max key is the last key-value from the last extraction 0 if first extraction . This incremental decoupled approach avoids introducing trigger latency in the insertion datapath be it custom triggers or modified Slony and depending on your setup could scale better with number of CPUs etc . However if you also have to track UPDATE s and the sequential key was added by you then your UPDATE statements should SET the key column to NULL so it gets a new value and gets picked by the next extraction . You would not be able to track DELETE s without a trigger . Is this what you had in mind when you mentioned Talend I would not use the logging facility unless you cannot implement the solution above logging most likely involves locking overhead to ensure log lines are written sequentially and do not overlap overwrite each other when multiple backends write to the log check the Postgres source . The locking overhead may not be catastrophic but you can do without it if you can use the incremental SELECT alternative . Moreover statement logging would drown out any useful WARNING or ERROR messages and the parsing itself will not be instantaneous . Unless you are willing to parse WALs including transaction state tracking and being ready to rewrite the code everytime you upgrade Postgres I would not necessarily use the WALs either -- that is unless you have the extra hardware available in which case you could ship WALs to another machine for extraction on the second machine you can use triggers shamelessly -- or even statement logging -- since whatever happens there does not affect INSERT UPDATE DELETE performance on the primary machine . Note that performance-wise on the primary machine unless you can write the logs to a SAN you d get a comparable performance hit in terms of thrashing filesystem cache mostly from shipping WALs to a different machine as from running the incremental SELECT . Comment : The Talend option was going to adopt the approach you suggested .. . maybe I should revisit . But you highlighted the key issue tracking the INSERTs and UPDATEs and DELETEs . So no matter what I do there is some work to be done to get it to work cleanly and efficiently .. . surprised this is not a very common issue with lots of examples on web . Thanks for your well thought through response . Comment : A potential issue with the primary-key-threshold idea is that postgres sequences are non-transactional . That is a transaction that inserted with a lower PK may commit after a transaction that inserted with a higher PK . Your ETL strategy could therefore miss inserts assuming a read committed isolation-level . This would rarely be an issue unless you have huge insert volume or long transactions but it is something to consider if you cannot tolerate data loss during ETL .", "Question : I know ICR is basically used for handwritten hand printed data recognition but can we leverage ICR to extract distorted bad quality machine printed text by any chance if not what is best way to solve the following problem .. . .. . I have a unstructured document which may run into 2 or more pages with in the document there are few date field which will be handwritten.now I want to convert this to text file . I have tried some fullpage ocr omnipage and abbyy etc tools which have ICR modules to convert into text file . they are good at full page OCR but when it encounter handwritten date it puts junk character instead of using ICR module there . I don t want go with form processing tools like parascript and A2ia which are position based and they work only with structured document . or can we use ICR to convert machine printed text and handwritten anyway it will work for hand return date in this case .. . .. . here my aim is to get the text file output from unstructured document with few hand written text like dates numbers .. . Answer : I have tried some fullpage ocr omnipage and abbyy etc tools which have ICR modules .. . .. . That is incorrect which explains the poor result . If you tried retail versions of OmniPage and ABBYY FineReader these software packages are OCR only without ICR support . I don t want go with form processing tools .. . .. . You may have to in some way but there are a few variations of the approach . This will have to be a marriage of two technologies either out-of-box or self-created but it will take more effort than just install and run it . Today it is assumed that there is no unstructured text ICR software that can deliver high quality result . Full-page OCR or unstructured text OCR machine text produces high quality result on machine text and garbage on hand-writing . You are right that ICR implies zonal recognition which allows to provide data types and backend dictionaries for improved recognition of hand-writing . For the simplest and fastest approach which may may also be most economical and least labor intensive I would use an unstructured form-processing package such as ABBYY FlexiCapture http : www.wisetrend.com abbyy flexicapture.shtml . It requires some non-programming setup to locate zones . Zones may change position and this software still finds them and then uses appropriate algorithm OCR ICR to read zones content . Supports OCR ICR OMR checkmarks BCR barcode . Also has built-in full page OCR . I use this software in-house resell it and have over 14 years of experience fine-tuning it . For a potentially more economical way but one that may require manual marriage of at least two technologies two purchases instead of one plus labor - may not be most economical at end of day I would use some kind of OCR SDK for machine text and some kind of ICR-capable SDK for hand-written zones . Depending on consistency in location of those zones you may be able just to supply coordinates . If they shift then need to do deeper analysis of zones location to pass them to ICR . ICR-recognized text will need to be returned to be inserted into appropriate places among OCRed text . In my opinion with a number of tools that can do that out of box now I would use something out of box instead of writing it myself because there are several major challenges that need to be solved : zone identification two technologies integration workflow .

Every two weeks 80 weeks of data needs to be extracted . 2 . Extracts take a long time and are resource intensive so we would like to distribute the load of the extract over time . 3 . The first 8-12 weeks are the most important and need be updated more often over the two week window . Data further out can be updated less frequently to the point where the last 40 weeks+ could even just be extracted once every two weeks . 4 . Every two weeks the start date shifts two weeks ahead and so two new weeks are extracted . 5 . Extract procedure takes a start and end date this is already made and should be treated like a black-box . The procedure could be run for multiple date spans in a day if required but contiguous dates are faster than multiple blocks of dates . 6 . Extracts blocks should be no smaller than 2 weeks and probably no greater than 16 weeks . Longer blocks are possible but at 16 weeks are already a significant load to the system . 7 . 4 contiguous weeks of data takes about 1 hour approximately . It takes a long time because the data needs to be generated calculated . 8 . Data that is newly extracted replaces the old data for the timespan . No need to merge or diff the data it is just replaced . 9 . This algorithm needs to be built into a SQL job which will handle the daily process triggered once a day only . My initial thought was to create a sliding schedule pretty much . Rotate the first 4 week block every second day and then the second 4 week block every 3 to 4 days . The rest of the data would be extracted in blocks in smaller chunks over the two week period . What I am going to do will work but I wanted to spend some time seeing if there might be a better way to approach the problem . Mainly looking for an algorithm to do the start end date schedule for the daily extract . Comment : Do you have a downstream data mart or are you pulling data from an online system Comment : @dfb It s all internal . 4 contiguous weeks of data takes about 1 hour approximately . It takes a long time because the data needs to be generated calculated and part of the reason we don t want to put to much load on the system doing work . Comment : @dfb 4 weeks of data is about 1 million rows which isn t that much . It s generating the rows that takes a long time .", "Question : I have a client website that is running on Prestashop v1.4 .. . .. . Because it has been maintained by a previous developer who modified core files and generally made a big mess the upgrade module no longer works properly . Given that the client is handing over the project to me and wants a new theme implemented I am moving straight to Prestashop 1.6 and using the Compass Boostrap 3 default theme as a base . Obviously the important thing is that the clients data should be migrated . So my question is is it possible to make a clean export from Prestashop 1.4 of only the actual sales and website access data skipping anything like module configs etc in order to reimport it all to Prestashop 1.6 This way my client can keep his order data-access data products payments etc and I can build a new theme without having to fight with an old installation or theme that have hardcoded rubbish in it .

I know these infoboxes can optionally include up to two airport images which could be exterior photos exterior photos or logos and also a map image is optional .

The binary-data is compactly stored as a byte array and can be easily created modified and analysed . You can create BitString objects from binary octal hex integers big or little endian strings bytes floats files and more . You can then analyse and modify them with simple functions or slice notation - no need to worry about bit masks etc . There is also a concept of a bit position so that you can treat it like a file or stream if that s useful to you . Properties are used to give different interpretations of the bit data . Plus there s support for the standard bit-wise binary operators packing unpacking endianness and more .

Answer : I notice that you use .capacity when you probably mean to use .size . That could make you do extra unnecessary work as well as giving you the wrong answer . Your loop in find set bit iterates over all 32 bits in the word . You can instead iterate only over each set bit and use the BSF instruction to determine the index of the lowest bit .

They should be able to be from 4 bits to 20 bits . I have never worked with bit vector before but I guess that one would one create arrays of unsigned bytes that you manipulated using the usual AND OR XOR operations . The important restriction here is : I cannot rely on any libraries other than those supplied with standard Python . I think I know how I would do this in C using arrays of 8 bit unsigned bytes : e.g . to turn the 18th bit of a zeroed array into a one I would do something like my bit array 3 1 2 .. . .. . But since Python is dynamically typed and does not have a built-in array type how would I go about doing this in a pythonic way And is it possible how to express a bit vector of size 20 I am thinking of perhaps making a 24 bit 3 byte vector and ignoring the 4 bits . Comment : What is the issue with relying on external libraries Comment : @ezod : Probably because this is homework .

One of the methods on the linked page above in action : .. . .. . After executing the above bitArray has the value 3 . How can I express in the code that I want it to consider all 4 bits .. . Answer : The constructor for BitArray bool accepts the values in index order - and then CopyTo uses them in the traditional significance so bitArray 0 is the least significant bit - so your true true false false ends up meaning 0011 in binary not 1100 . It s not ignoring the last two bits - it s just treating your initial array in the opposite order to the one you expected . If you want it to make the first-specified value as the most significant value when converting the bits to integers you ll need to reverse your input array . Comment : Ah..that makes sense then .

Am I using numpy wrong somehow Is there another Python library I can use that actually improves on Python s built-in int type Results : .. . .. . EDIT : .. . .. . There seems to be a lot of confusion about how single operations on Python ints longs are comparable to vector operations on entire numpy bit arrays . A 10 000-bit Python int long value when treated as a bit mask using the operator just like we can do with ints or longs in C C++ is directly comparable to a numpy bool array of length 10 000 because they both contain the same number of bits albeit represented in 2 different ways . The same is true for the other ways of representing 10 000 bits that I tried including using numpy packed bit arrays numpy int arrays and bit array string types from other libraries . They are all comparable because they are all computing the same function on the same sequences of bits . All that matters here is that I can represent all 10 000 bits and that I can perform bitwise operations on them . If anyone can suggest a more efficient way to represent long fixed-length sequences of bits that allows bitwise-operators and to be used that is what I am looking for . If you re still confused as to how a Python int long value can store the same information as a numpy bool array or a numpy binary-valued int array please refer to the int to bits function in the code above it demonstrates how to extract the bits out of a Python int long which shows that performing the operation on two 10 000-bit ints is fundamentally the same as performing it element-by-element on a list or array of 10 000 Boolean values .

By the way the OP s size is 10000 not 1000 . Comment : That doesn t matter still - you are comparing - bitwise-and of a single integer in all cases . Also - running the same operation 10000 times is not same as running the operation on Vector of 10000 elements . btw that 10000 is common for both pure python and numpy arrays There s no vector operation there . Also - for simple integers might still be optimized than single element numpy arrays need to look that up . Comment : @gabhijit Please check out the additional information I added to the question . An N-bit integer value contains the same information as an N-bit array of bools .

And there is a new method rand Bool to explicitly create an array of Bool . You can start using these new definitions in 0.3 with the Compat https : github.com JuliaLang Compat.jl package . .. . Answer : An Array Bool stores each true false value as a Bool which is represented internally as a UInt8 . So if your array has N elements it will take N bytes to store it . A BitArray stores each true false value as a single bit with conceptually 8 of them packed into a single UInt8 . Consequently it takes only N 8 bytes to store the array . A BitArray also has methods defined that handle all the required bit-twiddling operations for you . Depending on the operation BitArray s are sometimes slower than the corresponding Array Bool and sometimes faster .

Answer : In a rpg program if you set the inRT indicator the program stays in memory as long as the active group is alive . So you can call callbacks functions in the program even when it has returned . I d like to know if i can do the same in a ile C++ program . I ve tried and when i call a function of an ended ile C++ program i have a mch3402 message tried to refer to all or part of an object that no longer exists .. . .. . Of course i can write a service program instead of a program but that will make me change a lot of things . So before doing that i d like to know if i can do something equivalent to rpg inrt on in a ile C++ program . Comment : Sorry my bad my problem came from something else . When compiling with crtpgm option actgrp is entmod by default and it results on a new active group program when the main module is cpp . I ve changed to caller and it works fine now . Comment : Just a minor comment.. . The RT indicator return or INRT has no good use in ILE programs and is only useful in some Cycle programs . All that s needed for any ILE program in a non- NEW activation group that won t be reclaimed is to issue a RETURN statement . That s true whether LR is on or off though global files and variables may need special attention if a callback proc needs them . INRT is just a way to tell RPG internal logic to drop out of the Cycle back to the caller without ending and without an explicit RETRN or RETURN . If the Cycle isn t used it does nothing ." ] }

Answer : Zentyal to Zentyal connections don t work for normal clients . Zentyal allows you to define more than one VPN server . You should use a separate VPN server for other clients . Note that the two modes have different semantics in regard to how routing works for each of the VPN models . In brief : .. . .. . Zentyal-to-Zentyal VPN tunnels use RIP and exchange the static routes accessible to each server . For normal road-warrior clients networks that needs to be accessed by clients have to be published using the Advertised networks section . In addition it s better practice to use a separate VPN network for road warriors another VPN for server-to-server communications . If I guess correctly you d like to use Zentyal as a normal VPN client using a normal client bundle . It s a requested feature but I believe it s not available . You could configure the OpenVPN client manually in the Zentyal box unmanaged by Zentyal unless you use hooks .

Official description .. . .. . The pseudo-class concept is introduced to permit selection based on information that lies outside of the document tree or that cannot be expressed using the other simple selectors . .. . A pseudo-class always consists of a colon : followed by the name of the pseudo-class and optionally by a value between parentheses . .. . Pseudo-classes are allowed in all sequences of simple selectors contained in a selector . Pseudo-classes are allowed anywhere in sequences of simple selectors after the leading type selector or universal selector possibly omitted . Pseudo-class names are case-insensitive . Some pseudo-classes are mutually exclusive while others can be applied simultaneously to the same element . Pseudo-classes may be dynamic in the sense that an element may acquire or lose a pseudo-class while a user interacts with the document . Source http : www.w3.org TR 2011 REC-css3-selectors-20110929 pseudo-classes .. . .. . What does this mean The important nature of pseudo-classes is stated in the very first sentence : the pseudo-class concept .. . permit selection . It enables the author of an stylesheet to differ between elements based on information that lies outside of the document tree for example the current status of a link : active : visited . Those aren t saved anywhere in the DOM and there exists no DOM interface to access these options . On the other hand : target could be accessed via DOM manipulation you could use window.location.hash in order to find the object with JavaScript but this cannot be expressed using the other simple selectors . So basically a pseudo-class will refine the set of selected elements as any other simple selector http : www.w3.org TR 2011 REC-css3-selectors-20110929 selector-syntax in a sequence of simple selectors http : www.w3.org TR 2011 REC-css3-selectors-20110929 selector-syntax . Note that all simple selectors in a sequence of simple selectors will be evaluated at the same time . For a complete list of pseudo-class check the CSS3 selector recommendation . Example .. . .. . The following example will color all even rows gray ccc all uneven rows which aren t dividable by 5 white and every other row magenta . Pseudo-elements .. . .. . Official description .. . .. . Pseudo-elements create abstractions about the document tree beyond those specified by the document language . For instance document languages do not offer mechanisms to access the first letter or first line of an element s content . Pseudo-elements allow authors to refer to this otherwise inaccessible information . Pseudo-elements may also provide authors a way to refer to content that does not exist in the source document e.g . the : : before and : : after pseudo-elements give access to generated content . .. . A pseudo-element is made of two colons : : followed by the name of the pseudo-element . .. . This : : notation is introduced by the current document in order to establish a discrimination between pseudo-classes and pseudo-elements . For compatibility with existing style sheets user agents must also accept the previous one-colon notation for pseudo-elements introduced in CSS levels 1 and 2 namely : first-line : first-letter : before and : after . This compatibility is not allowed for the new pseudo-elements introduced in this specification . .. . Only one pseudo-element may appear per selector and if present it must appear after the sequence of simple selectors that represents the subjects of the selector . .. . Note : A future version of this specification may allow multiple pseudo-elements per selector . Source http : www.w3.org TR 2011 REC-css3-selectors-20110929 pseudo-elements .. . .. . What does this mean The most important part here is that pseudo-elements allow authors to refer to . . otherwise inaccessible information and that they may also provide authors a way to refer to content that does not exist in the source document e.g . the : : before and : : after pseudo-elements give access to generated content . . The biggest difference is that they actually create a new virtual element on which rules and even pseudo-class selectors can be applied to . They don t filter elements they basically filter content : : first-line : : first-letter and wrap it in a virtual container which the author can style however he want well almost . For example the : : first-line pseudo-element cannot be reconstructed with JavaScript as it heavily depends on the current used font the fonts size the elements width floating elements and probably the time of the day . Well that s not entirely true : one could still calculate all those values and extract the first line however doing so is a very cumbersome activity . I guess the biggest difference is that only one pseudo-element may appear per selector . The note says that this could be subject to change but as of 2012 I don t believe we see any different behavior in the future it s still in CSS4 http : dev.w3.org csswg selectors4 pseudo-elements .

Comment : I agree with DanMan s comment on SLaks answer in that pseudo-classes don t really act as filters but more as descriptors . For example : not .someclass : nth-child even doesn t mean to filter out elements that don t have .someclass and among the remaining elements filter out the even occurrences . Instead it represents any element that is both : not .someclass and : nth-child even of its parent at the same time .

I m not sure why I hadn t thought of posting it myself after my recent blitzkrieg on questions with the pseudo-selector tag http : meta.stackexchange.com questions 111323 retagging-questions-with-the-pseudo-selector-tag .. . .. . Answer : Pseudo-Class .. . .. . A pseudo-class is way of selecting certain parts of a HTML document based in principle not on the HTML document tree itself and its elements or on characteristics like name attributes or contents but on other phantom conditions like language encoding or the dynamic state of an element . The original pseudo-class defined dynamic states of an element that are entered and exited over time or through user intervention . CSS2 expanded on this concept to include virtual conceptual document components or inferred portions of the document tree e.g . first-child . Pseudo-classes operate as-if phantom classes were added to various elements . RESTRICTIONS : Unlike pseudo-elements pseudo-classes can appear anywhere in selector chain . Example pseudo-class code : .. . .. . A page that demonstrates a rendering of the above pseudo-class code .. . .. . Pseudo-elements .. . .. . PSEUDO-ELEMENTS are used to address sub-parts of elements . They allow you to set style on a part of an element s content beyond what is specified in the documents . In other words they allow logical elements to be defined which are not actually in the document element tree . Logical elements allow implied semantic structure to be addressed in CSS selectors . RESTRICTIONS : Pseudo-elements may only be applied to external and document-level contexts - not to in-line styles . Pseudo-elements are restricted in where they can appear in a rule . They may only appear at the end of a selector chain after the subject of the selector . They should come after any class or ID names found in the selector . Only one pseudo-element can be specified per selector . To address multiple pseudo-elements on a single element structure multiple style selector declaration statements must be made . Pseudo-elements can be used for common typographic effects such as initial caps and drop caps . They can also address generated content that is not in the source document with the before and after An example style sheet of some pseudo-elements with properties and values added follows . The following rule selects the first letter of a heading 1 and sets the font to 2em cursive with a green background . First-letter selects the first rendered letter character for a block-level element . .. . .. . Sources : Link http : www.d.umn.edu lcarlson csswork selectors pseudo dif.html", "Question : I know there is a : focus selector . I can t seem to find use of or documentation of a : blur selector . Is there one .. . Answer : There is no : blur pseudo-class in CSS . The dynamic pseudo-classes http : www.w3.org TR selectors dynamic-pseudos like other pseudo-classes and in fact all other selectors represent states they do not represent events or transitions between states in terms of the document tree . To wit : the : focus pseudo-class represents an element that is in focus it does not represent an element that has just received focus nor does there exist a : blur pseudo-class to represent an element that has just lost-focus . Similarly this applies to the : hover pseudo-class . While it represents an element which has a pointing device over it there is neither a : mouseover pseudo-class for an element that has just been pointed to nor a : mouseout pseudo-class for an element that has just been pointed away from . If you need to apply styles to an element that is not in focus you have two choices : .. . .. . 1 . Use : not : focus with less browser support : .. . .. . input : not : focus button : not : focus .. . Styles for only form inputs and buttons that do not have focus .. . .. . .. . .. . 2 . Declare a rule that applies to any element regardless of its focus state and override for elements that have focus : .. . .. . input button .. . Styles for all form inputs and buttons .. . .. . .. . input : focus button : focus .. . Styles for only form inputs and buttons that have focus .. . Comment : would .button : not : focus equal .button They elect the same but the latter has a specificity of 10 and the first a specificity of 20 . Comment : @Torsten Walter : No they re different .button will match all elements with that class whether or not they are in focus while .button : not : focus will never match the elements that are matched by .button : focus . The reason why you use .button and .button : focus together is to take advantage of the cascade . But yes the latter is less specific . Comment : Right . I didn t think about it from that perspective . Comment : What if you want to style something only after a user focused on it the left For example you wouldn t want to shout at someone for not entering a password when they load the page only after they left the input . Comment : @Marcel : Then you will need to use a JavaScript event handler for example to update the element with a class corresponding to your desired styles . CSS only works with states and not events which means as far as CSS is concerned an element is either in focus or not in focus . In particular it doesn t know whether or not the element has been focused since the page was loaded unless you tell it by updating the DOM after the fact something only a script can do .", "Question : The CSS language pseudo-class to allow us specify different styles for different languages like so : .. . .. . However this doesn t work in IE7 so I ve been using an attribute selector : .. . .. . They seem to do the same thing but are there any subtle differences And if not why does CSS even have a language pseudo-class when the attribute selector does the exact same thing .. . Answer : According to the spec http : www.w3.org TR CSS2 selector.html lang .. . .. . If the document language specifies how the human-language of an element is determined it is possible to write selectors in CSS that match an element based on its language . For example in HTML HTML4 the language is determined by a combination of the lang attribute the META element and possibly by information from the protocol such as HTTP headers . XML uses an attribute called xml : lang and there may be other document language-specific methods for determining the language . .. . The pseudo-class : lang C matches if the element is in language C . Whether there is a match is based solely on the identifier C being either equal to or a hyphen-separated substring of the element s language value in the same way as-if performed by the operator . The matching of C against the element s language value is performed case-insensitively for characters within the ASCII range . The identifier C does not have to be a valid language name . That is : .. . .. . 1 . It works for the many other ways of specifying a language besides the simple lang attribute . Most importantly as detailed in @BoltClock s answer it will use the language specified in whatever manner on a container element not just on the element itself since language is inherited by child elements . 2 . It uses semantics i.e . : lang en and : lang us will both match span lang en-us . 3 . It is guaranteed to be case-insensitive whereas .. . .. . The case-sensitivity of attribute names and values in selectors depends on the document language . Comment : Thank you for your answer", "Question : Is it possible to have pseudo-classes using inline styles .. . .. . Example : .. . .. . I know the above HTML won t work but is there something similar that will P.S . I know I should use an external style sheet and I do . I was just curious if this could be done using inline styles . Comment : Good question . It isn t possible afaik but that s not a limitation I ve ever thought about before . Comment : possible duplicate of Is is possible to create inline pseudo styles http : stackoverflow.com questions 986618 is-is-possible-to-create-inline-pseudo-styles .. . Answer : No this is not possible . In documents that make use of CSS an inline style attribute can only contain property declarations the same set of statements that appears in each ruleset in a stylesheet . From the Style Attributes spec http : www.w3.org TR css-style-attr : .. . .. . The value of the style attribute must match the syntax of the contents of a CSS declaration block http : www.w3.org TR CSS21 syndata.html rule-sets excluding the delimiting braces whose formal grammar is given below in the terms and conventions of the CSS core grammar http : www.w3.org TR CSS21 syndata.html syntax : .. . .. . .. . declaration-list .. . : S declaration S declaration .. . .. . .. . .. . Neither selectors including pseudo-elements nor at-rules nor any other CSS construct are allowed . Think of inline styles as the styles applied to some anonymous super-specific ID selector : those styles only apply to that one very element with the style attribute . They take precedence over an ID selector in a stylesheet too if that element has that ID . Technically it doesn t work like that this is just to help you understand why the attribute doesn t support pseudo-class or pseudo-element styles it has more to do with how pseudo-classes and pseudo-elements provide abstractions of the document tree that can t be expressed in the document language . Note that inline styles participate in the same cascade as selectors in rule sets and take highest precedence in the cascade important notwithstanding . So they take precedence even over pseudo-class states . Allowing pseudo-classes or any other selectors in inline styles would possibly introduce a new cascade level and with it a new set of complications . Note also that very old revisions of the Style Attributes spec did originally propose allowing this http : stackoverflow.com questions 18133155 inline-css-pseudo-classes however it was scrapped presumably for the reason given above or because implementing it was not a viable option .", "Question : When using namespaces in CSS you can select for example any div element in any or no namespace by using a namespaced type selector : .. . .. .

From what I can make out in the CSS grammar http : www.w3.org TR selectors w3cselgrammar it is not valid . But I may be misreading the grammar .

Comment : Oh yeah sorry I do understand the difference notice that the question does say pseudo-class I just got the title wrong Comment : I just came across your bug report : bugs.webkit.org show bug.cgi id 89748 https : bugs.webkit.org show bug.cgi id 89748 .. . Answer : Namespaces as part of the document language do not apply directly to pseudo-classes or pseudo-elements as they re defined in CSS and not the document language e.g . XML . Element types and attributes however are defined in the document language as opposed to CSS which is why they can be namespaced . Consequently in a sequence of simple selectors the universal selector specifically means any type . The universal selector is only implied for other simple selectors and pseudo-elements when used without a namespace this is why selectors like .foo target type text : first-child and : : before are valid and generally used with languages like HTML where CSS is most commonly used for styling . From the spec http : www.w3.org TR selectors universal-selector : .. . .. . If a universal selector represented by i.e . without a namespace prefix is not the only component of a sequence of simple selectors http : www.w3.org TR selectors sequence selectors or is immediately followed by a pseudo-element http : www.w3.org TR selectors pseudo-elements then the may be omitted and the universal selector s presence implied . Therefore in your example the selector is invalid because there s neither a universal selector or a type selector between the and the : : .. . .. . If you specify a namespace you must specify the universal selector if you don t select a specific type instead : .. . .. . The same goes when selecting elements in an ns namespace : .. . .. .

I m not sure why I hadn t thought of posting it myself after my recent blitzkrieg on questions with the pseudo-selector tag http : meta.stackexchange.com questions 111323 retagging-questions-with-the-pseudo-selector-tag .. . .. . Answer : From the Sitepoint docs : .. . .. . A pseudo-class is similar to a class in HTML but it s not specified explicitly in the markup . Some pseudo-classes are dynamic they re applied as a result-of user interaction with the document . - http : reference.sitepoint.com css pseudoclasses . These would be things like : hover : active : visited . .. . Pseudo-elements match virtual elements that don t exist explicitly in the document tree . Pseudo-elements can be dynamic inasmuch as the virtual elements they represent can change for example when the width of the browser window is altered . They can also represent content that s generated by CSS rules . - http : reference.sitepoint.com css pseudoelements . These would be things like before : after : first-letter .", "Question : How to write : hover and : visited condition for a : before I m trying a : before : hover but it s not working .. . Answer : This depends on what you re actually trying to do . If you simply wish to apply styles to a : before pseudo-element when the a element matches a pseudo-class you need to write a : hover : before or a : visited : before instead . Notice the pseudo-element comes after the pseudo-class and in fact at the very end of the entire selector . Notice also that they are two different things calling them both pseudo-selectors is going to confuse you once you run into syntax problems such as this one . If you re writing CSS3 you can denote a pseudo-element with double colons to make this distinction clearer . Hence a : hover : : before and a : visited : : before . But if you re developing for legacy browsers such as IE8 and older then you can get away with using single colons just fine . This specific order of pseudo-classes and pseudo-elements is stated in the spec http : www.w3.org TR selectors selector-syntax : .. . .. . One pseudo-element may be appended to the last sequence of simple selectors in a selector . .. . A sequence of simple selectors is a chain of simple selectors that are not separated by a combinator . It always begins with a type selector or a universal selector . No other type selector or universal selector is allowed in the sequence . .. . A simple selector is either a type selector universal selector attribute selector class selector ID selector or pseudo-class . A pseudo-class is a simple selector . A pseudo-element however is not even though it resembles a simple selector . However for user-action pseudo-classes such as : hover 1 if you need this effect to apply only when the user interacts with the pseudo-element itself but not the a element then this is not possible other than through some obscure layout-dependent workaround . As implied by the text standard CSS pseudo-elements cannot currently have pseudo-classes . In that case you will need to apply : hover to an actual child element instead of a pseudo-element . .. . .. . 1Of course this does not apply to link pseudo-classes such as : visited as in the question since pseudo-elements aren t links . Comment : It should be pointed out that that puts the hover on the parent element - which causes the decoration to be applied even if the : : after pseudoelement is not under the mouse as long as its parent is . Comment : It should also be noted that there are a number of things that don t respond to this because of the way the layout rules are specified e.g . text-decoration . Comment : @Chris Krycho : Indeed - I actually happen to have an explanation for this specific issue with regard to pseudo-elements here http : stackoverflow.com questions 11474780 hoverbefore-text-decoration-none-has-no-effects 11481121 11481121 . Of course it s worth clarifying that the issue itself has no connection with pseudo-class pseudo-element selectors but is as you point out a layout issue . Comment : @BoltClock I upvoted that answer very shortly after I left this comment . Huzzah . Comment : Sinlge colon : designates pseudo-classes and double colon : : designates pseudo-elements .

Answer : You can t force a certain pseudo-class to apply using jQuery . That s not how pseudo-classes especially dynamic pseudo-classes work since they re designed to select based on information that cannot be expressed via the DOM spec http : www.w3.org TR selectors pseudo-classes .

Smashing Magazine http : coding.smashingmagazine.com 2011 03 30 how-to-use-css3-pseudo-classes seems to essentially say html and : root are the same thing but surely there must be a difference .. . Answer : From the W3C wiki http : www.w3.org wiki CSS Selectors pseudo-classes 3aroot : .. . .. . The : root pseudo-class represents an element that is the root of the document .

However this doesn t work in IE7 so I ve been using an attribute selector : .. . .. . They seem to do the same thing but are there any subtle differences And if not why does CSS even have a language pseudo-class when the attribute selector does the exact same thing .. . Answer : In HTML both the : lang pseudo-class and the attribute selector will match an element with the corresponding lang attribute . The difference is that a browser may have other ways of determining the language of a given element when testing against the : lang pseudo-class which may be defined by the document language and or the implementation whereas an attribute selector will only check an element for that given attribute without any accompanying document-based semantics . For example in HTML the pseudo-class will also match any of the element s descendants for which there isn t a different lang depending on how a browser determines the language for those descendants . Usually the descendants will inherit the language attribute from their ancestor if it is not explicitly set . From the spec http : www.w3.org TR selectors lang-pseudo : .. . .. . The difference between : lang C and the operator is that the operator only performs a comparison against a given attribute on the element while the : lang C pseudo-class uses the UAs knowledge of the document s semantics to perform the comparison . .. .

Comment : @3to5businessdays : Yes although I should point out that modern browsers actually have both HTML and XML parsers - which one is used is determined by the content-type given by the server .

Answer : Apache tomee-1.7.x EE6 is using Apache OpenWebBeans-1.2.x which is a CDI-1.0 specification implementation .

From research I had assumed it would be enough to place the older quarts jar in the WEB-INF lib of my web-app and as per the Tomcat class loading information here http : tomcat.apache.org tomcat-6.0-doc class-loader-howto.html it would be looked up before the quartz-2.1.6.jar in the catalina.home lib directory this doesn t seem to be the case .

Is the webapp designed for Tomcat or Java EE TomEE is definitely not comparable to Tomcat . Any Tomcat or Jetty or any other custom stack targeted webapp will fail in some way when deployed to a standard Java EE server . Comment : Problem at least suggests a misconfigured CDI environment . Perhaps webapp is indeed Tomcat targeted and bundles some CDI libraries along while that s completely unnecessary when deployed on a standard Java EE server which already provides several Java EE API implementations such as CDI and JSF out the box . Comment : ok problem seemed to be omnifaces-version related : I was using 2.2-RC2 now updated to 2.3 and no exception anymore Comment : I d rather suspect a dirty build . Or does it also fail with 2.2 and 2.1 non-RC Comment : Technically 2.2 or newer shouldn t deploy on a stock TomEE 1.x because it uses JSF 2.1 instead of JSF 2.2 . So likely your TomEE instance has been modified to use JSF 2.2 . .. . Answer : TomEE is after WildFly one of most tested servers for OmniFaces particularly because it uses almost everywhere in Java EE a different implementation as compared to WildFly Apache vs Oracle . In the OmniFaces compatibility matrix https : github.com omnifaces omnifaces wiki Compatibility-Matrix you can find TomEE versions which successfully ran through all pages in OmniFaces showcase http : showcase.omnifaces.org . Those exceptions mentioned in your question will be thrown when CDI BeanManager http : docs.oracle.com javaee 7 api javax enterprise inject spi BeanManager.html couldn t find the OmniFaces EagerBeansRepository https : github.com omnifaces omnifaces blob master src main java org omnifaces cdi eager EagerBeansRepository.java which is an @ApplicationScoped bean . This in turn indicates a misconfigured CDI environment e.g . wrong beans.xml or missing JNDI listener configuration or a dirty build e.g . duplicate libraries . Verifying the CDI configuration and performing a full clean rebuild should solve the problem . At least OmniFaces 2.2 or newer is technically incompatible with TomEE 1.x because TomEE 1.x ships with JSF 2.1 and OmniFaces 2.2 or newer has a hard dependency on JSF 2.2 due to new o : viewAction tag . So unless you modify TomEE to provide JSF 2.2 OmniFaces 2.2 or newer won t deploy and should fail deployment with below exception : .. . .. . java.lang.NoClassDefFoundError : javax faces component UIViewAction .. . .. . The latest OmniFaces version which successfully deploys on a stock TomEE 1.7.x server is OmniFaces 2.1 . If you want to use OmniFaces 2.2 or newer on a stock TomEE then you need to upgrade to TomEE 7.x .", "Question : I recently installed apache-tomee-webprofile-1.7.2 on to a Red Hat Enterprise Linux Server 6.6 .

Comment : Question : Do I need to have anything deployed before I can access this page Is there not a default page that is accessed when first installed As I don t currently have anything deployed so I wondered if this could be it . .. . Answer : In TomEE 1.7.2 the webapps tomee folder is missing this is why 404 error occurs . I don t know if it is a bug or it is intentional . In 1.7.1 webapps tomee folder is still there . But it is actually not so important . This page only says that Your server is fully installed . I think that it is useful only when you install a drop-in WAR TomEE in a Tomcat and so you can check if it is installed successfully . But when you download and use a native TomEE this check does not count . Just deploy your applicaton and enjoy it However if you still want TomEE GUI download version 1.7.1 and copy the tomee folder in the webapps folder into the webapps folder of 1.7.2 .", "Question : My OS is win 7 ultimate 32-bit .. .

Then I Run on Server the following test xhtml . But it renders a blank page . Obviously the xhtml was not compiled . So the bundled TomEE jars did NOT kick in . How can I make those bundled TomEE jars compile my test xhtml Comment : You said yourself TomEE already provides JSF libraries why exactly are you still selecting User Library instead of Library provided by Target Runtime Comment : @BalusC Because Eclipse does NOT compile xhtml unless I download JSF libraries Comment : I added the detailed explanation . I understand that the test xhtml was simply not compiled . The JSF tags were not interpreted correctly . This can only happen if the JSF libraries did not kick in to interpret the tags Comment : Is your blank page problem answered here stackoverflow.com q 3112946 http : stackoverflow.com q 3112946 If JSF libraries were not found you d get ClassNotFoundException on FacesServlet instead and the webapp deployment would block altogether . Comment : @BalusC Thank you very much . Just as you said the answer is there change the url-pattern from faces to .xhtml .. . Answer : TomEE has MyFaces as JSF implementation in tomee lib folder .

The Apache Tomcat TomEE 7.0.68 1.7.4 page comes up fine on both local and remote instances . I have done my due diligence reading TomEE documentation and internet searches . On the local Windows instance when any of the following buttons are clicked the browser goes directly to the page . But on the remote instance of TomEE pressing the same buttons causes a small sign-on dialog to popup . There is only one user id in the tomcat-users.xml file . When the userid and password are used access is denied . It was my understanding the Fedora id used to run TomEE-plume should be configured as nologin .

Question 2 Why won t the id in tomcat-users.xml work Comment : It seems the tomcat-users.xml file is only loaded on startup . Once recycled all worked . .. . Answer : Just repeating the answer here that you already know that way this question doesn t come up as having no answer . No need to select this as the correct answer . tomcat-users.xml is indeed only read at startup you must bounce the JVM in order to pickup changes . If you want to be able to add remove users on the fly or change their roles without restarting the JVM consider using an LDAP backed security repository .

I developed an Enterprise application in Netbeans 7.1.2 . It runs successfully using the default Glassfish server . With the need to change the server I downloaded and installed Tomee+ server and made some changes to make Tomee Manager Interface work on my system . I deployed the .ear file Glassfish server output into Tomee+ by placing it in the Tomee webapps folder with the server in the running state . It gets automatically deployed and appears in the Tomcat Web Application Manager interface . Then by providing the suitable path in the address-bar like http : localhost : 8080 app-war faces app.xhtml it provides the frontend screen but the backend process is not working if I click the submit button . Instead it simply provides a status page like HTTP Status 500 - javax.el.ELException : javax.ejb.EJBTransactionRolledbackException : Transaction was rolled back presumably because setRollbackOnly was called during a synchronization . My question is : what went wrong with the steps I took for deploying it in Tomee+ server .. . Answer : no more verbose stack btw can you try to : 1 check you have in tomee.xml the line 2 put your ear in apps instead of webapps .. . .. . The point is by default can be configured with the snapshot next release tomee extracts the ear in a folder simply removing the extension webapps your-ear for instance and then tomcat takes this folder as a webapp so your deployment is no more the one expected . That s why moving it over a folder not managed by tomcat apps is often enough . That s said Glassfish transaction management is sometimes too tolerant why i ask the full stack you got .", "Question : I need to setup a Tomcat 8.5.x server version in Eclipse .

It s a quite useless check and the adapter should allow you to start the server anyway but nobody has though of that yet . For years and with every version of Tomcat this is always a problem . To patch you can do the following : .. . .. . cd tomcat or tomee home lib .. . mkdir catalina .. . cd catalina .. . unzip . . catalina.jar .. . vim org apache catalina util ServerInfo.properties .. . .. .

Is there a problem because TomEE already uses another CDI-Framework OpenWebB Is there a possibility to get TomEE running with Weld Comment : I am curious to why you would want to do this .. . Answer : The fundamental issue in the code you posted is that org.jboss.weld.environment.servlet.Listener is just needed for plain ServletContainers . E.g . integrating Weld into jetty or Tomcat if you DO NOT have a full Java EE server . The pendant in Apache OpenWebBeans is WebBeansConfigurationListener .. . .. .

Answer : My TomEE jsf project renders as expected when running locally but renders extremely slowly when deployed remotely . My remotely deployed jsf pages render slowly when a relatively large number of components relative to just displaying the template page with are the result-of a call to data sources . Rendering times measure in minutes when there are more than just a few rows in the table . Any ideas of where to look to isolate this problem Edit 2 : I have deployed on multiple remote-server environments . Rendering time of query results in dataTable seems to depend on bandwidth availability . Traveling to the physical location of the remote-server directly logging onto the remote-server and accessing the application via localhost in any browser yields the result-of nearly instantaneous rendering of the query results in the dataTable tag . Can it be that jsf is generating a huge html file size such that bandwidth becomes a constraint Edit 1 : The first thing that I thought was that the remote-server was doing a memory swaps from RAM to disk . It may be but that led me to make sure of checking the memory allocated to the JVM by TomEE in catalina.sh . See catalina.sh CATALINA OPTS below . I have found StackOverflow posts about logging being turned on off for JSF but no reference of where this setting is . My logging.properties files seem to be identical remote and local for tomee s and the jvm s . I also found posts about Mojarra s version of the API having an exponential time-complexity but this project uses Apache MyFaces . The problem seems to be some type of TomEE or JVM configuration issue . When I run the application on the locally installed version of TomEE the same pages render in milliseconds . I am using Apache MyFaces 2.1.13 . From pom.xml .. . .. . I ll gladly post the entire pom.xml but logic tells me that if the project renders pages at a different rate depending on the TomEE container that it is deployed in then the issue is elsewhere .

For further context I have 50 files total comprising 40 jpegs and 10 pdfs - this is represented correctly in the filer table : filer file . Filer image also shows the 40 images correctly . doing a dumpdata filer.file results in only the pdf entries being output .. . Answer : This is a workaround not quite the answer .

Comment : Usually to be injected TestClassToInject should be defined in one of your modules . Only than it becomes injectable . That means that class has to be created by Guice . In Ignite there is a way to emulate that behavior if you cannot do it for some reason : create an instance of TestClassToInject your self and than call context.injectMembers instance Comment : Thanks your patience I m still learning DI so I might be missing something . I am already able to create the TestClassToInject class using context.getInstance TestClassToInject.class inside of my main application class GluonApplication which extends ParticleApplication so I think the Guice stuff is working OK since TestClassToInject has a noarg public constructor .

Answer : If you check any of the Gluon mobile samples http : gluonhq.com support samples or if you create a new project with the Gluon plugin you will notice that the addViewFactory calls are done just once on the init method which is called once before the Application.start method .

Comment : Definitely Orientation improvements are on the roadmap : Providing an orientationProperty so you can listen to changes in orientation and react properly either changing the view or just modifying its layout and also coercing portrait or landscape mode should be possible .

I commented where the line 142 that the error-log is telling Comment : Gluon Mobile doesn t support Stream API hence the NoSuchMethodError . Remove the call to ArrayList.stream in dragDropped and see if it works .. . Answer : The error has nothing to do with events . If you check the code you have commented out : .. . .. . it contains stream and since JavaFXPorts is running on Android iOS with Java 7 versions Java 8 streams are not supported yet . Lambda expressions are supported though thanks to the retrolambda project https : github.com orfjackal retrolambda . Use an old for-nested loop instead . If you really need full support for Streams you may have a look at the streamsupport project https : sourceforge.net projects streamsupport . Also Android N will support streams and other Java 8 features as well but it is still in preview . Comment : Wow you are awesome thanks for helping us on this forum . I noticed that error .

Comment : @YvesGonzaga Just wanted to note that if you consider to give streamsupport a try you ll have to use release 1.4.2 for now . The two more current versions 1.4.3 and 1.5 have a bug that prevents it from running when JavaFXPorts is present . This will be fixed in release 1.5.1", "Question : I am having problem running my JavaFX Port Application on Genymotion . When I try to install it on the emulator . It says Failure INSTALL FAILED CPU ABI INCOMPATIBLE . So I go into flashing it with ARM Trnaslation . Finally I successfully installed my application on genymotion . The problem is when I try to run the app it says Unfortunately Gluon has stopped . The error-log below . Can you help me with this I am a total newbie in JavaFX Port . .. . Answer : I ve installed Genymotion and the ARM translation and I can reproduce the error . If you set on Genymotion- Settings- ADB use custom Android SDK tools and provide the path to your android sdk then you can open a console window go to Android sdk platform-tools and when the emulator running type : adb logcat -v threadtime .

This error : UnsatisfiedLinkError : dlopen failed : data app com.gluonhq.fiftystates-1 lib arm libactivity.so has unexpected e machine : 40 has been reported several times as a bug in the arm translation . Basically it means there are no x86 libraries and the translation from arm libraries has failed . If you want to run the app in an emulator you may try BlueStacks . Once you have installed it you can double click on your apk and it will be available on BlueStacks . Then you can run it . Gluon app http : i.stack.imgur.com VjRtR.png .. . .. . If for any reason the app crashes you can run adb logcat as well to find out about any possible exception . I ve noticed that apps that work fine on mobile fail easily on the emulator . So the best solution is running and testing your apps in a real device . Comment : Hello I have updated my post . I ve added the error-log . Comment : While in your case it seems Genymotion manages to initially load the libactivity.so library then it crashes with a sigsegv . Either way JavaFXPorts projects don t include x86 libraries .

Answer : While there s no explicit API for drawing lines polylines or polygons on top of a MapView the MapLayer is a layer where you can draw any JavaFX Shape providing you take care of scaling it to the map coordinates . For that if you have a look at the PoiLayer class https : bitbucket.org gluon-oss gluon-maps src tip src main java com gluonhq maps demo PoiLayer.java you can see that for any MapPoint defined by latitude and longitude you can get a 2D point defined by x and y and you can draw a node at that position : .. . .. .

Answer : If you run this short test with a regular JavaFX Application you will notice the same behavior : .. . .. . toolbar http : i.stack.imgur.com rNtYB.png .. . .. . According to JavaDoc for a node s managed property : .. . .. . Defines whether or not this node s layout will be managed by it s parent . If the node is managed it s parent will factor the node s geometry into its own preferred size and layoutBounds calculations and will lay it out during the scene s layout pass . If a managed node s layoutBounds changes it will automatically trigger relayout up the scene-graph to the nearest layout root which is typically the scene s root node . This means the borderpane s top region keeps the preferred size given by the toolbar which by default is managed regardless its visibility . When you set the visibility of a ToolBar to false you need as well to release its space by setting managed to false : .. . .. . EDIT .. . .. . In your case you have also a MenuBar and the ToolBar managed property is already bound to its visibility so you only need to set : .. . .. .

Answer : Obviously wp-editor won t show up as you re making ajax call which only returns ajax response but not wp-editor which is built by javascript on that page . In short ajax call can get server-side text response but not javascript editor which is built on client-side and needs javascript processor to process . Following can be suedo example of what can be done to make editor working . 1 . just below add product button from where ajax call is being made print a editor using php code and set its display to none so editor doesn t appear on page . e.g . 2 . php function for ajax response should only return text content only .

It didn t work . .. . Answer : The content style setting works on elements inside the body of the HTML document in TinyMCE - what you really want to do is make the background of the body a different color . To do this look at the content css setting for the init : .. . .. . This allows you to load an external CSS file for use inside TinyMCE . Then in the content.css file you can do something like this : .. . .. . Now the background-color of the editor itself will be gray based on the above example . If you use content css you really don t need content style as you can put all of your CSS in the external CSS file . EDIT : .. . .. .

You would need a way to pass that color into the configuration object a JS variable would work but this should also get the job done . Comment : The background-color needs to be dynamic so relying on a predefined style sheet won t work . Since the user selects from a color-picker the background would need to be any number of colors . Comment : @HWD - please see my edit . Perhaps that would work for your use-case Comment : This seems to change the background-color of the excerpt textarea not the primary text area . How do I target that instead Comment : So do you have a custom page template What is the excerpt textarea vs the primary textarea If you have multiple TinyMCE instances on the page how are you defining the configuration for each one When I use that code in my init the body of the editor turns yellow as I expect but the default page template has one single TinyMCE editor . see screenshot above Comment : I m using the standard Edit Page like you are in the example except for that I have excerpts enabled so there is a textarea for excerpts as well .

Thanks Comment : Why are you as a client-side trying to send data to swagger hi or editor The server would tell you what it needs via the swagger ui or yaml... .", "Question : null .. . Answer : I have been using API workbench to edit a RAML 1.0 document as I like the ability to view a preview of what the docs will look like in the side pane . However I recently discovered that absolutely none of the documentation generators work with RAML 1.0 at the moment . Therefore you can write a RAML 1.0 spec but there are no tools for the creation of automatic documentation -which mostly negates the need to write a RAML document in the first place I considered dropping back to 0.8 but without the ability to define types RAML loses most of its luster . I realize the existing tools will eventually support RAML 1.0 but I am at a loss for a stopgap solution and there appears to be no time frame on when support will be enabled for 1.0 . As a result I then considered converting to swagger due to being impressed with the documentation output of swagger-ui editor . However I discovered that there is no ability to save documents in swagger-editor -which is one of the most basic functions of an editor This issue https : github.com swagger-api swagger-editor issues 174 was reported in 2014 but it doesn t look like there is any resolution and despite what common sense would suggest it appears the developers don t think this functionality is even necessary and instead advocate periodically downloading the file and then saving it locally . This is extremely unsafe as a browser crash accidental tab closure or authoritarian forced Windows restart policy will wipeout a good portion of your work One can only imagine how many hundreds of hours of API development work have been lost due to the lack of a save button on Swagger-Editor . There are various online services that add this functionality of course but it is outrageous for those who live outside of San Francisco to pay exorbitant sums of money it s often the cost of a Netflix subscription or more just to have the ability to save a swagger document As a result-of these issues both Swagger and RAML 1.0 seem unsuitable for a sensible development - instant documentation workflow at the time of this writing based on my research . However because I cannot possibly be the only person who has found this situation unsatisfactory in the past two years I hold out hope that one of the 3 solutions ranked in order of desirability exists out there somewhere : .. . .. . 1 . A local or locally hostable documentation tool that supports RAML 1.0 or a method for enabling RAML 1.0 in an existing tool . 2 . An alternative IDE for Swagger preferably in the mold of API Workbench http : apiworkbench.com docs which doesn t require setting up docker-container and running configuring an entire node.js stack just to edit and compile single file . 3 .

Answer : The json function is added to the response object by express.js but the swagger generator generates code which uses connect.js not express .

Answer : You can create an extra step in your Maven build-system to validate the Swagger document against the Swagger 2.0 Schema https : github.com OAI OpenAPI-Specification blob master schemas v2.0 schema.json .

Answer : See this answer http : stackoverflow.com questions 31300756 can-swagger-autogenerate-its-yaml-based-on-existing-express-routes 31332524 31332524 for help in deciding how to generate Swagger docs for a project . You can either manually create the docs for your API and have Swagger UI serve them or you can use a node package like swagger-node-express https : www.npmjs.com package swagger-node-express which will do most of the documenting automatically . See the link above for pros and cons of each of these options .

The issue here is 1 2 and 3 are appearing for the sample petstore api definition but not for the API definitions that I am writing . If you download Swagger UI 2.1.4 and run it you will be able to see it for yourself . Comment : Ritwik running SwaggerUI 2.1.4 locally with the Petstore API definition yields me the VALID .. . button as expected .

Note that the ModifierKeys value can be a combination of values so if you want to detect that CTRL was pressed regardless of the state of the SHIFT or ALT keys you will need to perform a bitwise comparison as in my sample above . If you want to ensure that no other modifiers were pressed you should instead check for equality : Comment : Over HERE http : stackoverflow.com a 7078186 153923 you said that data is in the KeyData field . No one here has mentioned KeyData https : msdn.microsoft.com en-us library system.windows.forms.keyeventargs.keydata.aspx . Are these answers incorrect Comment : Good catch @jp2code ModifierKeys is a property on Control such as a windows forms form that will give you information on what modifier keys that are currently being pressed . KeyData that comes with the key-events contains information about what modifier keys that were pressed together with the key that caused the event . In retrospect I d say that ModifierKeys is more interesting together with button click or similar events and that it would be more accurate to use KeyData during key-events .", "Question : I ve looked around a lot and I know you can detect the ctrl keys ctrl+c ctrl+v etc with the keydown event in javascript and it s often used so that the event isn t captured by other processes however I want to handle it through the keypress event the purpose being handling through one event rather than 2 and hopefully allowing for consistency when using other keyboard-shortcuts for the same function now it seems like it should be possible after all the keypress event object has Boolean properties for alt ctrl shift etc . and the character code for keypress events that do go through are different then the key itself for example z keypress event is charCode 122 where ctrl+z keypress event is charCode 26 . So the question is is there a way to prevent the default from intercepting the ctrl keys so that the keypress event can handle them for my particular instance I m using chrome but I also want general answers . UPDATE .. . .. . ive found that all of the default of the ctrl keys can be prevented for example ctrl+s attempting to save the page using the from inside the keydown event like this .. . .. . note : this only prevents the defaults that are preventable things like ctrl+t for a new tab in chrome can not be prevented .. . .. . however the problem here is that this also stops the keypress event from occurring is there a way to then pass the event to the keypress event in a way that will have the keypress properties meaning things like the charCode will now be defined .. . Answer : Reading this from another site it states - .. . .. . Keyboard events is one of wilder parts of frontend development . There are inconsistencies and cross-browser problems . .. . But still there are recipes which help to cope with ordinary situations easily . .. . There are following keyboard-events : .. . .. . keydown .. . A key is pressed down . keypress .. . A character key is pressed . keyup .. . A key is released . .. . There is a fundamental difference between keypress and keydown . .. . Keydown triggers on any key press and gives scan-code . Keypress triggers after keydown and gives char-code but it is guaranteed for character keys only . Given this the control key can t be captured by keypress because it doesn t generate a character .

Hope this helps Comment : I think you missed the whole point I wanted to capture it with the key press event that was the whole purpose of the question Comment : Like I specifically said I know you can capture it with key down but I want to do it with key press Comment : I see your issue . Mind if I change my answer . It seems you won t be able to do this since keydown and keyup are different than key press . Comment : Yes please keypress just so you know is a more processed version of key down and key up and it includes things that the others don t such as the shift and ctrl being part of the same event . With keydown shift+a gives you two events the shift and the a with keypress it gives you one event for the A Comment : I ve updated my answer to include why the control key alone can t be captured alone with keypress .

Something weird is happening here Based on this how can I detect both of these keys being pressed at the same time .. . Answer : Here are a couple of vanilla Javascript solutions that should help you : .. . .. . Solution 1 .. . .. . Check which keycode was pressed down and if the shiftkey is down using native the event object . .. . .. . Solution 2 .. . .. . Keep a global variable for the detecting if the shift key is down and use that in your keydown handler . You ll also need to reset it with a keyup event handler . Comment : The trouble here is that the string returned by event.key is actually different depending on whether or not CTRL is held . Shift is a lot easier and was the first thing I implemented because it doesn t change the value of key . Even if you create a global boolean for CTRL and map it to keyUp keyDown events you still won t be able to detect the CTRL+Z character by looking for event.key z because z will never be returned by event.key so long as CTRL is held . You could theoretically make your global CTRL boolean toggle each time that key is pressed but that d be weird . : Comment : That s why I d recommend using which or keyCode rather than key as in my example . Each key is represented as a unique number . These attributes are considered deprecated now but based on what browsers you may need to support they will be the most universally useful and all future browsers will support them for legacy purposes . Comment : If I were writing a plain JavaScript handler I d be inclined to agree with you In this case I m trying to stick to the event handlers that are provided by the paper.js library which don t give you direct access to the keyCodes that are spawned by the event handler . But you re right what you really want in this case is event.keyCode if it s available", "Question : What would be some sample code that will trap the Ctrl+Tab and Ctrl+Shift+Tab for a WPF application We have created KeyDown events and also tried adding command bindings with input gestures but we were never able to trap these two shortcuts . .. . Answer : You have to use KeyUp event not KeyDown .. . Comment : Interesting . Haven t tried this but can you please explain why Comment : Sure Siz . When you are trying to capture 2 or more key strokes at the same time you cannot use KeyDown checking for e.Key because it captures one key at a time . If KeyDown is necessary like doing something when the user is holding down a key combination for example you should use KeyDown and the Keyboard class specifically IsKeyDown testing for specific keys . Comment : Sorry I don t understand what you re trying to say here . The KeyUp event also only passes a single Key value in e.Key . Can you give a specific example where handling KeyUp instead of KeyDown would be better for capturing 2 or more keystrokes at the same time Thanks . Comment : @RayBurns The idea behind capturing KeyUp is that at the moment of KeyUp all modifier keys are already pressed . You only need checking them to figure out the whole key combination within the same handler . If you work with KeyDown instead you have hard time telling Shift+Ctrl e.g . change keyboard layout from Shift+Ctrl+A . Comment : Both Up and Down events are exposed for a reason . All depends on the use-case . In some cases using Down is much better eg . you want to repeat action bound to they key as long as it s pressed without the need of tapping they key repeatedly . You d prefer to use Up if you want to prevent from action firing more then once by mistake the key is pressed for too long by mistake .", "Question : I ve been wondering if I can detect CTRL and SHIFT key being pressed WITHOUT using keydown event . The reason is that I am creating some sort of Grid Viewer in JavaScript and I implemented selecting different items by holding CTRL or SHIFT key as it functions in most common viewers editors and so on .

Then I hold CTRL or SHIFT and click on the item but it acts normally as keydown hasn t been triggered . Any way of omitting this Perhaps not but it can be confusing for customers who will treat it as my own obvious Bug . Comment : If they treat it as a bug of yours that s their fault .

How can Tampermonkey fire on a simultaneous ctrl alt and e key I have tried ctrlKey and altKey . I ve found nothing that works . How can I edit the script below to fire on Ctrl + Alt + e instead of just e .. . Answer : The keypress event is fired as soon as a key has been pressed . If you are pressing multiple keys it will fire the event for each press so they are considered independent key presses . Instead you can use both the keydown and keyup events to detect multiple key presses . You can have an object that contains the 3 keys and a boolean state . On the keydown event if the current key matches a key in the object you set the state to true for that key . On the keyup event you reset the state for the current key to false . If all 3 states are true at the time of the last key press then fire the event . See this example https : therelentlessfrontend.com 2012 11 13 detect-multiple-key-press-in-javascript-for-your-website that achieves this logic using jQuery . Update Brock s answer is a better solution for you using modifier keys in combination with a single key code target as the ctrlKey and altKey modifiers are detected in combination not handled independently .

For me keyDown didn t work keyU p worked instead for the same code . I don t know why but it seems because keyDown event happens directly after you press any key even if that was ctrl key so if you pressed ctrl+Up you will press ctrl key before the UP key and thus the event will occur before you can press the other also pressing the second key will triggers the event again . While using KeyUp will not trigger the event until you release the key so you can press ctrl and the press the second key which will trigger one event .", "Question : I m trying to enable editing commands in my paper.js application such as CTRL+z for undo .

The goal here was to be able to fire a user event that can be detected by this select -based polling mechanism even if the event eventually needs to be consumed using kevent later . This looked like the kind of thing EVFILT USER was born to do but a quick experiment indicates that select doesn t report the kqueue s fd as being ready to read when an event is added and triggered in the kqueue it just times out or blocks forever .

When passed as input it forces EV ERROR to always be returned . When a filter is successfully added the data field will be zero . My understanding however is that it is trivial to make bulk changes to a kqueue without draining any pending events simply by passing 0 for the nevents parameter to kevent and thus drawing no events from the queue . With that in mind why is EV RECEIPT necesary Some sample code https : developer.apple.com library mac technotes tn2050 index.html in Apple documentation for OS X actually uses EV RECEIPT : .. . .. . But seeing as the changes array is never examined after the kevent call it s totally unclear to me why EV RECEIPT was used in this case . Is EV RECEIPT actually necessary In what situation would it really be useful .. . Answer : If you are making bulk changes and one of them causes an error then the event will be placed in the eventlist with EV ERROR set in flags and the system error in data . Therefore it is possible to identify which changelist element caused the error . If you set nevents to zero you get the error-code but no indication of which event caused the error . So EV RECEIPT allows you to set nevents to a non-zero value without draining any pending events . Comment : Ok this makes sense but it doesn t correlate with the code in the Apple example that I linked . The comment in that code says : Create the kqueue and set it up to watch for SIGCHLD . Use the new-in-10.5 EV RECEIPT flag to ensure that we get what we expect - however it calls kevent with just a single event uses EV RECEIPT and checks neither the return from kevent nor the values in the return events . Any clue as to what the comment means by we get what we expect - or is the use of EV RECEIPT in this case bogus Comment : I think in this case setting nevents to zero would achieve identical behaviour as the return-value is not checked . But this may be a pattern that is replicated in other code where the return-value is checked . The expectation being that the new filter is returned and not a pending event .", "Question : From the Kqueue Wikipedia Page http : en.wikipedia.org wiki Kqueue : .. . .. . Kqueue provides efficient input and output event pipelines between the kernel and userland .

The kqueue mechanism indeed does work as a means to be notified when an app s Documents directory is modified . 2 .

Unfortunately there is no form of notification when the copy is done . At least none that I have found . What I hope Apple will realize is there needs to be a notification for iTunes synch is done because this seems to be a general problem .

Answer : Edit : that answer misses the question because it s not about using kqueue . But if someone else finds the question by the title it may be helpful anyway .. . .. . .. . I ve often seen the following behaviour : if a client dies and the server does a select on the client s socket descriptor select returns with return code 0 and FD ISSET fd will be true for that descriptor .

For a normal connection using that to detect a client s death works fine for us but there seems to be a different behaviour when the socket connection is tunneled but we haven t yet managed to figure that out completely . Comment : yeah but the point is kqueue has the behaviour of replacing select so im not using a select in any case Comment : ok sorry and let me guess kevent doesn t behave like select in that case Comment : yip kevent is kind of eventlistener which returns me a list of all sockets that trigger a special event i.e . something is ready to write or read . so if there is a socket that got closed by client kevent just won t threw any events of that socket anymore .

Answer : If you check the type it s of type uintptr t which is a standard type big enough to hold both the largest integer or a pointer .

Answer : It s unfortunately not possible . Signal delivery notifications via kqueue occurs after the process itself has already reacted to the signal i.e . they are a post-delivery notification rather than an in-delivery notification . If the process receives multiple signals between calls to kevent then all the system does is aggregate the number of times the signal has been delivered in the data field of the kevent structure . This means that there s no way to obtain the signal information as by the time you ve called the kevent data the signal has already been delivered to the process and the signal details have been discarded . There is no internal mechanism that keeps a record of the underlying signal information which could be delivered by the kevent . I was reading some of the big nerd ranch book which seems to indicate that the kqueue handling for signals would not occur if there was a handler registered for the process . This does not appear to be the behaviour on Yosemite you receive the event for signals even if there is a handler registered using either sigaction or signal .", "Question : null .. . Answer : I ve got a kqueue watching a single item : an empty Mach port set . kevent64 says there are no events available and select indicates the kqueue is not ready for reading . But poll says the kqueue is readable - though this doesn t appear to be the case-when subsequently calling kevent64 to read the supposedly ready event s . The code I m using is below . You can build it with something like gcc -Wall -std c99 -o test test.c and then run it with . test or whatever . It prints out return values from kevent64 count of events actually retrieved after an attempt was made to read 1 without waiting select count of file descriptors ready for reading after polling and poll count of file descriptors ready for reading after polling . The output I d expect would be something like this indicating that kevent64 select and poll all agree that the kqueue is empty . But what I actually get is this showing that kevent64 and select say one thing and poll another - and furthermore that even after poll has indicated the kqueue is readable kevent64 still says there is no event to be read this being the reason for the second kevent64 call . The 1 value for revents is POLLIN indicating supposedly that data may be read without blocking . The result is the same if I specify POLLRDNORM and POLLRDBAND independently .

What another ways does exist to watch large directory structures on FreeBSD Does Linux handle such amount of data using inotify Thanks for any suggestions Comment : Could this question answers http : apple.stackexchange.com questions 40705 monitor-a-folder-for-changes-and-run-a-command-when-a-change-is-detected be a solution for your situation Launchd is ported to FreeBSD . .. .

Here is my js-ctypes code : Comment : Well that should work probably you did something wrong in the code you haven t shown us . So show us the code . Comment : Yeah I ve had similar problems with using bridge FFI libraries first you figure out how to write your code from documentation and sample code written for C or C++ or ObjC or whatever and then when you have a problem you have to translate it all back before a relevant expert can understand it . If you can create an MCVE http : stackoverflow.com help mcve in C it would help if you can t just post one in JS . Comment : No never mind The point I was going to make is that most editors don t actually overwrite your file they instead write a temp file and then rename it over your original so you re not going to get a contents-modified notification . But you should still get an unlink notification NOTE DELETE which you don t seem to have missed and you re not getting that either . Comment : You may want to test doing similar things outside of Sublime e.g . cp myfile tmpfile mv myfile thefile and make sure that triggers NOTE DELETE on myfile . Comment : What gets written to the console both the JavaScript console and the system-console log In what context is this running e.g . a browser Could there be a sandboxing issue .. . Answer : I just realized that you re not monitoring the .js file you re monitoring its directory . That makes everything a lot less mysterious . The short version is : If you open a file and write it that doesn t change anything on the directory . If you atomically save a file that does change the directory but Sublime 2 doesn t atomically save by default . So to watch for any changes to any file in the directory you need to enumerate all files in the directory and add them all to the kqueue as well as the directory . Watching the directory will catch atomic saves and new files being created watching the files will catch overwrites . Files being unlinked will trigger both . If you re worried about performance well kqueue is designed to handle switching on 10000 file descriptors and neither UFS nor HFS+ is a good filesystem for hundreds of thousands of directory entries in the same directory so you re probably OK but you may want to add some code that warns or aborts if the directory turns out to be massively huge . .. . .. . If you want to understand why this is necessary you have to think about how the two different kinds of saves work . A write just writes to a file-descriptor . That file-descriptor could have one directory entry link on the filesystem but it could just as easily have none e.g . it was created in a temporary namespace or you just unlinked the file after creating it or many e.g . you ve created hard links to it . So it can t actually update the directory entry for the file because there is no such thing . An atomic save on the other hand works by creating a new temporary file writing to that and then rename -ing the temporary over the original file . That rename has to update the directory replacing the entry pointing at the old file with an entry pointing at the new file . Of course it also sends a DELETE notification for the file itself because the file is losing a link . And you ll also usually sends an ATTRIB because most apps want the new file to have the same extended attributes extra forks etc . .. . .. . There is an obvious race-condition here : if a file is moved or deleted between the readdir and adding it to the kqueue you ll get an error . You may want to handle that error by generating an immediate notification or maybe you just want to ignore it after all from the user perspective it s not much different from the case where someone deletes a file between the time your program starts and the time you do the readdir . Comment : I think that claiming that kqueue is designed to handle switching on tens of thousands of file descriptors is an exaggeration . There s a limit on the number of file descriptors a process can have open and it s probably not multiple tens of thousands . On OS X it s 10240 . Also if you re watching a whole hierarchy of files you need to start and stop watching as files are added to and removed from the hierarchy which is non-trivial to do efficiently . Comment : @KenThomases OK you re right it was designed for 10000 not 10s of thousands edited . Anyway I m betting he s interested in watching directories of around 100 files and he can just raise a warning if the directory is bigger than expected as I said . Comment : @KenThomases For the rest : I don t think he wants to watch a whole hierarchy just a flat directory . And it s non-trivial to do in the first place but the obvious way to do it is efficient enough . At any rate what other option does he have if he wants to write code that works on FreeBSD and OS X Either require a wrapper or gamin-style server or kqueue up the whole directory himself . Comment : Thank you for such an awesome reply Yep diretory is less than 100 files typically but it s API other users might have more so thanks very much for this . I think I ll just tell users of the API if they want to watch a file for overwriting they should specifically add a watch for it . Comment : @Noitidart : If you re building something for general-purpose use you may want to look at one of the existing wrappers which give you an FSEvents -like interface on top of whatever the OS provides on everything from FreeBSD to pre- inotify linux to Windows in the most efficient way possible which includes doing things like using a daemon process and subprocesses to manage all the kqueue fd s instead of making each client do it . I don t know the current state of the art for such wrappers but it s worth looking into rather than reinventing the wheel .", "Question : I am running into an issue spawning a large number of processes 200 under MacOS X Mountain Lion though I m sure this issue is not version specific . What I am doing is launching processes in my test it is bin cat which have their STDIN STDOUT and STDERR connected to pipes -- the other end of which is the spawning parent process . The parent process writes data into the STDIN of the processes which is piped to the bin cat child processes which in turn spit the data back out of STDOUT and is read by the parent process . bin cat is just used for testing . I am actually using kqueue to be notified when there is space available in the STDIN pipe . When kqueue notifies you with a EVFILT WRITE event that space is available the event also tells you exactly how many bytes can be written without blocking . This all works well and I can easily spawn 100 child bin cat processes and everything flows through the pipes without blocking all day long . However when I crank up the number of processes to 200 everything grinds to a halt when the single kqueue service thread blocks on a write call to one of the STDIN pipes . The event says that there is 16384 bytes available basically an empty pipe but when the program tries to write exactly 16384 bytes into the pipe the write blocks anyway . Initially I thought I was running into a max . open files issue but I ve jacked up the ulimit for open files to 8192 so that is not the issue . What I have discovered from some googling is that on OS X STDIN STDOUT STDERR are not in fact files or pipes but are actually devices . When the process is hung running lsof on the command-line also hangs with a warning about not being able to stat the file system : .. . .. . As soon as I kill the process lsof completes . This reinforces the notion that STDIN OUT ERR are in fact devices and I m running into some kind of limit . Does anyone have an idea of what limit I am running into for example is there a limit on the number of device that can be created Can this be increased somehow .. . Answer : Just to answer my own question here . This appears to be related to how MacOS X will dynamically expand a pipe from 16K to 32K to 64K and so on . My basic workaround was to prevent the pipe from expanding . It appears that whenever you fill the pipe completely the OS will expand it . So when the kqueue triggers that I can write into the pipe and indicates that I have 16384 bytes available to write I simply write 16384 - 1 bytes . Basically whatever it tells me I have available I write at most available - 1 bytes . This prevents the pipe from expanding and is preventing my code from encountering the condition where a write to the pipe would block even though the pipe is non-blocking .", "Question : I recently did some testing with kernel events and I came up with the following : .. . .. . Does it make sense to use a kernel event for accepting sockets My testing showed that I was only able to handle one accept at once even if the eventlist array is bigger Makes sense to me cause .ident sockfd is only true for one socket . I thought the use of kevent is mainly to read from multiple sockets at once . Is that true Is this how a TCP server is done with a kqueue implementation : .. . .. . .. . .. . Listening Thread without kqueue .. . Accepts new connections and adds FD to a worker kqueue . QUESTION : Is this even possible My testing showed yes but is it guaranteed that the worker thread will be aware of the changes and is kevent really thread safe .. . .. . Worker thread with kqueue .. . .. . Waits on reads on file descriptors added from the listening thread . QUESTION : How many sockets at once would make sense to check for updates .. . .. . Thanks .. . Answer : Normally you use kqueue as an alternative to threads . If you re going to use threads you can just set up a listening thread and a worker threadpool with one thread per accepted connection . That s a much simpler programming model . In an event-driven framework you would put both the listening socket and all the accepted sockets into the kqueue and then handle events as they occur . When you accept a socket you add it to the kqueue and when a socket handler finishes it works it could remove the socket from the kqueue . The latter is not normally necessary because closing a fd automatically removes any associated events from any kqueue . Note that every event registered with a kqueue has a void userdata which can be used to identify the desired action when the event fires . So it s not necessary that every event queue have a unique event handler in fact it is common to have a variety of handlers . For example you might also want to handle a control channel set up through a named pipe . Hybrid event thread models are certainly possible otherwise you cannot take advantage of multicore CPUs . One possible strategy is to use the event queue as a dispatcher in a producer-consumer model . The queue handler would directly handle events on the listening socket accepting the connection and adding the accepted fd into the event queue . When a client connection event occurs the event would be posted into the workqueue for later handling . It s also possible to have multiple workqueues one per thread and have the accepter guess which workqueue a new connection should be placed in presumably on the basis of that thread s current load . Comment : First of all thank you for your explanation . I understand but my testing showed that the server then cannot accept multiple connections at once : and I m quite unsure if reading writing and listening in the same thread makes much sense . For example on a client read I need to parse the packet then do some mysql queries and then create a response in this time no client could connect to my server.. . so is it really done this way Comment : @d3l : Then you are doing something wrong : Perhaps you need to ask a different question with a minimal compilable example . Comment : I made a little example explaining the problem . Greetings Comment : @rici I liked the question I have asked a similar question just now myself . But the question that I think your answer addressed is - can multiple threads add file descriptors to the kqueue are kqueues thread safe If so how would one go about doing this Also if OP was able to find a way to do this could he she share it with me Comment : @rici A clarification to the above comment . I do not want to create a circular dependance with the kqueue module and the TCP logic . I wanted to do this in a manner that would have them both be separate entities . If I used what you said about the accept call adding the file-descriptor to the kqueue then that logic will have to be added to the kqueue module", "Question : From the Kqueue Wikipedia Page http : en.wikipedia.org wiki Kqueue : .. . .. . Kqueue provides efficient input and output event pipelines between the kernel and userland . Thus it is possible to modify event filters as well as receive pending events while using only a single system call to kevent 2 per main event-loop iteration . This contrasts with older traditional polling system calls such as poll 2 and select 2 which are less efficient especially when polling for events on a large number of file descriptors .. . .. . That sounds great . I target FreeBSD for my server and I m handling a significant amount of network socket fd s - using a select on them all and figuring out who to read data from . I d rather use kevent calls to get higher performance since that s what it s there for I ve read the man page for kevent on FreeBSD here http : www.gsp.com cgi-bin man.cgi section 2 topic kevent but it s cryptic to me and I m not finding good resources that explain it . An example of using kevent to replace select would solve my problem and would also help me get a better idea of how kevent is used . .. . Answer : What you do normally is use libevent http : www.monkey.org provos libevent which takes care of all the details for you and also means that you can move your program on to another OS which has a different scheme e.g . Linux and epoll for doing something similar . Comment : But I already do all the things this lib does that I care about other than using kevent for checking whether I read from fds or not . I wouldn t want to rewrite my codebase to use this lib just for that although if I was starting maybe I would . Also I cringe at something hosted at monkey.org Comment : Then perhaps libev is better for you freshmeat.net projects libev http : freshmeat.net projects libev Comment : Definitely wouldn t want a superset either Although I can look at these pieces of software and pull the answer together I guess but this is really not addressing the original question Comment : @Nektarios : Sure it does answer it . If you use one of those libraries on a BSD system it ll use kevent and not select ." ] }

You don t instantiate the Hub class or call its methods from your own code on the server all that is done for you by the SignalR Hubs pipeline . SignalR creates a new instance of your Hub class each time it needs to handle a Hub operation such as when a client connects disconnects or makes a method call to the server . .. . Because instances of the Hub class are transient you can t use them to maintain state from one method call to the next . Each time the server receives a method call from a client a new instance of your Hub class processes the message . To maintain state through multiple connections and method calls use some other method such as a database or a static variable on the Hub class or a different class that does not derive from Hub . If you persist data in memory using a method such as a static variable on the Hub class the data will be lost when the app domain recycles .

The backend app is basically a monitor that fires SignalR events back to the HTML based client . This all works fine amazingly well actually . However we need to restrict access to the server for authenticated users from the Web site . So basically if a user is authenticated on the Web site we need to somehow pick up the crendentials user name is enough and validation state in the backend app to decide whether to allow the connection as to avoid unauthorized access . Can anybody point at some strategies or patterns on how to accomplish this sort of auth forwarding Comment : I ve implemented token based security by passing a generated user token with each SignalR request via query-string ie . .connection.hub.qs . The client gens the key that cross-refs a user and on the server I pick up the token and then load up the user from the cross ref . It works but it s pretty ugly plus I can t figure out how to cleanly enforce the security short of calling a ValidateToken method that throws on error . Comment : Any update on this Have you found a better way to do it yet I m encountering the exact same situation . .. . Answer : SignalR does not provide any additional features for authentication . Instead it is designed to work with the authentication mechanism of your application . Hubs .. . .. . You should do authentication as you normally would and then use the Authorize attribute provided by SignalR to enforce the results of the authentication on the Hubs . The Authorize attribute can be applied to an entire Hub or particular methods in the Hub . Some examples : .. . .. . Authorize only authenticated users .. . Authorize Roles Admin Manager only authenticated users in the specified .NET roles .. . Authorize Users user1 user2 only authenticated users with the specified user names .. . .. . You can also require all Hubs to require authentication by adding the following method in the Application Start method : .. . .. . GlobalHost.HubPipeline.RequireAuthentication .. . .. . Persistent Connections .. . .. . You can use the user object in the request to see if the user is authenticated : .. . .. . request.User.IsAuthenticated Comment : I m not using ASP.NET to host this SignalR service so I don t think this works since there s no ASP.NET security or Identity to check .

Comment : Thank you for clearance . So now I have to ask what would you recommend instead of this Writing a function to hub for each different type of data Comment : That s the most straightforward approach .", "Question : By default there are a default of 1 000 messages stored in the ring buffer on the server . It doesn t make sense for me to send a lagging client 1 000 updates but rather just the most recent update . In WCF I can do this by using volatile data . I suppose I can emulate a volatile approach by reducing the buffer to 1 but not sure if this can be configured on a per hub basis or ideally on a per method basis . Does it matter if I use hubs or persistent connections with this .. . Answer : Even if you set the DefaultMessageBufferSize https : www.google.com webhp sourceid chrome-instant rlz 1C1CHFX enUS563US563 ion 1 espv 2 ie UTF-8 q defaultmessagebuffersize to 1 SignalR ensures each buffer will hold at least 32 messages . The primary purpose of this minimum buffer size is to ensure that SignalR s long-polling transport works somewhat reliably . If the buffer size was actually 1 a client connected via long-polling would be very likely to miss messages between polls . I understand that there are some applications where only the last message matters . Unfortantely as of now SignalR does not have a volitile messaging configuration . Setting the buffer size to 32 is about as good as it gets . At least the client shouldn t lag too far behind with that small of a buffer size . You are correct in assuming that there are multiple buffers but buffer sizes cannot be configured individually . SignalR creates one ring buffer per signal . A signal can be a connection id group name user name PersistentConnection name for when you call Connection.Broadcast and Hub name for when you call Clients.All . If you use Clients.All inside of multiple methods in a single hub all those calls will end up in a single buffer . EDIT : If you want to configure another SignalR endpoint with different settings inside of the same application you can do the following : Comment : How do I configure this on a per signal basis Comment : You cannot configure buffer sizes per signal . At best you could map two SignalR endpoints with different DefaultMessageBufferSize s but that would require an extra concurrent connection per client . Comment : OK I ll try to configure two endpoints . I m assuming I can do this on the same machine . Is GlobalHost.Configuration.DefaultMessageBufferSize a singleton How can I configure other endpoints on the same machine Comment : GlobalHost.Configuration is implemented as return GlobalHost.DependencyResolver.Resolve IConfigurationManager . If you pass your own resolver in via the HubConfiguration GlobalHost will not be used .", "Question : I m just starting out with SignalR and have created a custom resolver for SignalR so I can use Castle Windsor to inject dependencies via hub constructors . I kind of assumed that I would only need to register the dependencies but I found that it was also necessary to register the hubs themselves before my app would work . Is this expected If so what lifetime should I use for hubs Comment : I had a similar question here : stackoverflow.com q 21967542 1053381 http : stackoverflow.com q 21967542 1053381 .. . Answer : By default SignalR does not register each hub with the dependency resolver . Instead it uses an IAssemblyLocator to find available assemblies that might contain SignalR Hubs . Then the IHubDescriptorProvider searches through all the available assemblies for Hubs and creates HubDescriptor s . Lastly the IHubActivator takes a HubDescriptor and returns a newly instantiated SignalR hub using Activator.CreateInstance unless the Hub type associated with the HubDescriptor has been registered with the dependency resolver . In the latter case the Hub returned from the IHubActivator will be taken directly from the dependency resolver . Typically SignalR hubs are ephemeral meaning that they get created and destroyed for each Hub method invocation . This means that if you register your Hub with SignalR s dependency resolver you should make sure that a new Hub instance is returned each time SignalR resolves the Hub type . I strongly advise against registering a singleton Hub for several reasons : .. . .. . 1 . Hub methods can be called in parallel . When this happens Hub.Context can be overridden as part of the setup for another method call . This can lead to really subtle bugs . For example with a singleton Hub the following code might add a connection other than the caller to a group which could obviously be a big security issue : .. . .. . Authorize Roles Admin .. . public async Task JoinAdminGroup .. . .. . await Groups.Add Context.ConnectionId admin .. . .. . .. . .. . 2 . Hub.Dispose will be called after each activation . If you keep returning the same Hub it s Dispose method will be repeatedly called . This probably won t affect you unless you implement Dispose on your Hubs since the default Dispose implementation currently no-ops . 3 . IIS recycles AppDomains . When this happens you will be forced to reinstantiate your Hub anyway . Remember SignalR will automatically reestablish active connections after your app becomes unavailable for a short period of time as is the case with an AppDomain recycle so you can very well have a newly instantiated Hub dealing with pre-existing connections even if you register your Hub as a Singleton with the dependency resolver . https : github.com SignalR SignalR blob 2.0.1 src Microsoft.AspNet.SignalR.Core DefaultDependencyResolver.cs L79 Comment : Useful answer thanks .

Answer : I am working on application which has mutiple hubs . I have created hub proxy for all hubs at one places and using when required in future . From doc : .. . .. . Note : Normally you register event handlers before calling the start method to establish the connection . If you want to register some event handlers after establishing the connection you can do that but you must register at least one of your event handler s before calling the start method . One reason for this is that there can be many Hubs in an application but you wouldn t want to trigger the OnConnected event on every Hub if you are only going to use to one of them . When the connection is established the presence of a client method on a Hub s proxy is what tells SignalR to trigger the OnConnected event . If you don t register any event handlers before calling the start method you will be able to invoke methods on the Hub but the Hub s OnConnected method won t be called and no client methods will be invoked from the server . OnConnected event for all hub is triggered when there is atleast one event handlers . In my case if I have 20+ hubs then OnConnected method for all 20+ hubs will called which I don t think is a nice way . I am not able to think if this will really cause some performance issue if yes then is there any workaround by which I can delay onConnected call . Comment : Having multiple hubs is not suggested .

I started migrating my project from WCF polling duplex Silverlight 5 - ASP.NET 4.5 to SignalR 1.1.2 . The message data contract is polymorphic based on interfaces . Like IMessage MessageA : IMessage etc . - there is actually hierarchy of interfaces implemented by classes but it is not of much significancy for the question . I know polymorphic objects are not good for clients but client will handle it as JSON and mapping to objects is done only on server-side or client if it is .NET Silverlight .. . .. . On the hub I defined method like this : .. . .. . I created custom JsonConverters and verified the messages could be serialized deserialized using Json.NET . Then I replaced JsonNetSerializer in DependencyResolver with proper settings . Similarly on the Silverlight client-side . So far so good . But when I sent the message from client to server message got serialized to JSON correctly - verified in Fiddler server returned error that the parameter cannot be deserialized . With a help of debugger I found a bug in SignalR JRawValue class responsible for deserialization of parameter creates internally its own instance of JsonSerializer ignoring the provided one . Seemed to be quite easy fix by replacing .. . .. . with .. . .. . but I also found that the interface IJsonSerializer is going to be removed in future version of SignalR . What I need basically is to get either raw JSON or byte stream from HUB method so I could deserialize it by myself or a possibility to tweak the serializer by specifying converters etc .

But I would prefer to customize the serializer and having the type interface on the hub method .

How could I achieve this Comment : Good question . Sad to see no answers . I am also interested in implementing polymorphic message contracts . .. . Answer : If you use connection API instead of Hub API you can handle OnReceive event and get request as raw JSON string . Take a look at this example https : github.com SignalR SignalR wiki PersistentConnection . Ability to send pre-serialised data to clients using Hub API was added in 2.x version and i don t know about any way to do that in 1.x see github issue https : github.com SignalR SignalR issues 1546", "Question : I understand why SignalR doesn t give you access to the HttpContext http : stackoverflow.com questions 7854663 signalr-doesnt-use-session-on-server . However this is quite problematic for us . Let me explain : .. . .. . Our application is a Multi-Tenant application where the user chooses the environment while logging in . This basically registers the ConnectionStringName in the HttpSession . In our SignalR Hub we need to access the database on Disconnect . But this is not possible because we have no HttpContext at this point and cannot determine the environment to write to . Can anyone provide us with a suggestion how to solve this problem We re a bit stuck on this one . EDIT : Bonus point if your solution works in a Load-Balanced environment . Comment : Are you still looking for a solution here Comment : We implemented the feature in a completely different way . Comment : @Lodewijk Could you share your different way I m at the same situation . Comment : Lodewijk and @MarioLevrero can you workaround the problem Same issue here . .. . Answer : You can use something like a Dictionary to keep track of the ConnectionId of the user when they connect . Also using SQL Server to store the Session State may also help : http : support.microsoft.com kb 317604 .. . .. . SignalR does give you access to User.Identity.Name which you can use to track when the disoconnect is fired . Comment : Sadly the User info is not available : ..as well as the HubContext s User and Cookies will not be populated . github.com SignalR SignalR wiki Hubs https : github.com SignalR SignalR wiki Hubs Comment : Also we re in a load-balanced environment so the disconnect could end up on the other server where the dictionary is not populated . Comment : I have looked at some previous code and Context.User.Identity.Name does show the current logged in user . If the environment is load balanced you should maybe look at redis for SignalR . github.com SignalR SignalR wiki https : github.com SignalR SignalR wiki SignalR-with-Redis-Running-on-a-Windows-Azure-Virtual-Machine Comment : I meant that the User info will not be populated on Disconnect . I m relying on the docs for this . Haven t actually spiked it .", "Question : I am using SignalR with an ASP.NET Web Api server . I would like to be able to disconnect my hub on the client manually .

Answer : signalr hubs is not a physical file it s a dynamically generated JavaScript code http : www.asp.net signalr overview guide-to-the-api hubs-api-guide-javascript-client dynamicproxy . SignalR creates the JavaScript code for the proxy on the fly and serves it to the client in response to the signalr hubs URL . What you want to do is to create a physical file for the SignalR generated proxy http : www.asp.net signalr overview guide-to-the-api hubs-api-guide-javascript-client manualproxy that you can add to your single file : .. . .. . 1 . Install the Microsoft.AspNet.SignalR.Utils NuGet package . 2 . Open a command-prompt and browse to the tools folder that contains the SignalR.exe file . The tools folder is at the following location : .. . your solution folder packages Microsoft.AspNet.SignalR.Utils.2.1.0 tools .. . .. . 3 . Enter the following command : .. . signalr ghp path : path to the .dll that contains your Hub class .. . The path to your .dll is typically the bin folder in your project folder . .. . 4 . This command creates a file named server.js in the same folder as signalr.exe . .. . 5 . Put the server.js file in an appropriate folder in your project rename it as appropriate for your application and add a reference to it in-place of the signalr hubs reference . The problem is that you ll have to do this for every change in your hubs . Every . Single . time ." ] }

Comment : There s a Windows 7 API SDK that you can download from Microsoft. . Comment : And how is it different than the libraries that already come with Win 7 .. . Answer : That s not how DWM works : the contents of the thumbnail are never blitted onto the DC of your window . Instead the DWM composition engine will render the thumbnail directly over the contents of your window when the desktop is presented . There s no official way to access the image data of a DWM thumbnail unfortunately there is however a hack http : www.youtube.com watch v hRTgFTMnT U on the net that tries to access the underlying vertex data and render it in DirectX 9 .", "Question : I am trying to figure out how to use DWM to render a copy of a Window into my own desired location .

The thing happened on Windows 8 OS 6.2.9200.0 . When I tested my code it worked perfectly on any themes on Windows Vista 7 8 including classic ones and high contrast . So my question is why is this happening Is it possible that visual styles got disabled on Windows 8 And how should I resolve it Is there any event that notifies that visual styles got turned off I know that I can check if visual styles are enabled by using the property VisualStyleRenderer.IsSupported but I want at least to test my solution . And I don t know how to reproduce the situation . Comment : Invalid test use VisualStyleRenderer.IsSupported instead .", "Question : I have a simple Windows application here : .. . .. . http : www.bengoodger.com software chrome dwm app.cc .. . .. . My app provides a customized glass frame for when DWM compositing is active and a fully custom frame when it is inactive or not available . The customized glass frame consists of a enlarged title bar area which is reported by my implementation of WM NCCALCSIZE to be part of the client area since I would like to render transparent controls into it . So that this tall title bar area portion of my window is transparent I fill it with transparent black BLACK BRUSH in the simple example above which causes it to be drawn as glass by the DWM . When the system DWM is toggled e.g . by using the Appearance Settings control panel to switch to Vista Basic or Windows Standard or when an app that requires the system to disable DWM is launched my app switches to fully custom rendering mode by handling WM NCPAINT etc . When I switch back I would expect the reverse which mostly happens except my tall title bar area is now solid black . I ve found I can work around this issue by getting the window s placement hiding the window then setting the window s placement again in my WM DWMCOMPOSITIONCHANGED handling but this causes other horrible bugs least of which is window z-order munging . My question is - what am I doing wrong here It seems like the window is being put into a bogus state somehow and hiding showing it corrects it . How can I prevent this from happening Any guidance would be greatly appreciated . Note : I have narrowed this down somewhat . When DWM glass is in effect any part of the client area that is painted black that is rendered over the client area is rendered transparent . We noticed that when returning to Glass from non-Glass the client area is rendered solid black instead of transparent . However when the window is maximized and then restored the window returns to being transparent . When I subsequently drag size the window smaller the top portion window remains transparent . When I drag it larger the top portion of the window turns black again . It s as-if the DWM is caching the pixels behind the window and sizing the window larger causes it not to be able to paint anything there because its cache isn t large enough . I can t seem to find any DWM function to reset this state . It seems that Maximize Minimize then Restore or SetWindowPlacement are capable of tickling it though but have other undesirable side effects . .. . Answer : http : www.codeproject.com KB dialog rtaGlassEffectLib.aspx .. . .. . As you may have noticed the GlassEnabled property is a great one for testing if this feature is enabled by your system and then start using our library and call ShowEffect function to show the glass effect Now suppose the user has disabled enabled the Aero Theme while your application was running This may cause a problem in the appearance of your application . .. . To solve this problem two events were added to the library to keep track of the changes happening to the system while your application is running these two events are GlassEffectEnabled event and GlassEffectDisabled . .. . Now for people who like to know how stuff works . . I can tell that these events were implemented by monitoring the messages coming from the system to the windows to our application looking for the WM SYSCOLORCHANGE message that indicates that the system colors have been changed . So by doing a quick compare between the state of the GlassEnabled property before and after this message we can decide whether this feature has been enabled or not .", "Question : I am starting to believe that you can do nothing with Windows API .

Answer : I have been trying to incorporate the Windows 7 taskbar APIs in a regular MFC MDI multiple document interface application . I am using Visual Studio 2008 where I have redirected the SDK path to use the Windows 7 SDK . The idea is to provide custom live-preview bitmaps for each of the childframe windows that gets created inside the application . Though I have been able to make progress there is a bit of struggle that I am going through with the final bits and pieces which do not seem to go right.Just wanted to know if I am missing anything . Ok .. . .. . 1 . so we need a proxy window which I have as the live-preview APIs work only on top level windows this is a disappointment .

SetThumbnailForPreview hBitmap hwnd .. . DeleteObject hBitmap .. . .. . break .. . .. . .. . 2 . Both the functions CreateBitmapFromHandleAndResize and CreateBitmapFromHandle create a DIB aka device independent bitmap which are food for the APIs DwmSetIconicThumbnail and DwmSetIconicLivePreviewBitmap . Problem faced : The problem I am facing is in the live-preview bitmap area where the following code does the work . The hBitmap is a 32-bit depth DIB which when saved on the disk seems to be a proper screenshot of the child window that I would like to display . But when I preview it somehow the title bar and the bitmap doesn t seem to be of the same quality as of the window itself . In fact it looks like an out of focus representation of the child window . I would like to have the same quality image displayed because the user should not feel the difference . Currently I take the print of the entire window including the frame and position the live-preview exactly on top of the existing window so that when the live-preview is on the user is deceived to see the bitmaps instead of actual child windows . I hope this is the expected behaviour here of live-preview . Please let me know if I am wrong here . One other problem was the offset . Not sure whether I am doing something wrong here . But it simply does not work when I just do a diff of the two rects . The correction factor of 8 and 14 was done with a trial and error method My questions in a nutshell : .. . .. . 1 .

What I achieved is to simulate a shadow by using the technique being used in the Locus Effects article http : www.codeproject.com Articles 10879 Locus-Effects . Basically use a transparent window dynamically use alpha blending PNGs as simulated shadow and draw that around the sides and corners of the window move the transparent window when the real window moves etc .

I m currently attempting to write a small application that s built around the features available through the Windows DWM API e.g . DWM Thumbnails . One such feature would be the ability to dynamically select an area of the thumbnail from within the application and have it scaled up zoomed in . It may be possible to do this from DWM with some sort of set region function but I wanted to try my own route first before going too far into the API . Having recently found an example for Delphi http : www.delphigeist.com 2011 01 01 archive.html I had hoped to expand from the demo and build something more specific . I set about moving the code over to a Firemonkey FM2 application as I much prefer the visual features of the framework compared to VCL . With a few tweaks I managed to get it built but unfortunately it seems as though DWMRegisterThumbnail wouldn t return a valid result when running in the FMX application despite the VCL version working flawlessly . I then looked a little further and decided to give Hydra a shot . I copied the working VCL example over to a Hydra Plugin and created a Firemonkey host application . I correctly set up both parts and compiled . The DLL loaded correctly and I could see the VCL plugin interface inside the FMX host as expected . However upon trying to view the DWM Thumbnail of a window I was once again faced with the same issue I had when running the non-hydra FMX application . I then went about creating a VCL host application just to be sure it wasn t an issue specific to the VCL-FMX interaction . I compiled the VCL host loaded in the VCL plugin and again I could see the VCL plugin inside the VCL host . However once again I was still finding that I couldn t view thumbnails from DWM . Evidently it s not a Firemonkey-VCL interaction issue . Therefore I ve concluded it s an issue with running the DWM code from a DLL . Ideally I d like to have an FMX host application simply because it s easier for me to drop a TSelection over the thumbnail and deal with scaling in that way e.g . very little code and no need to look for a custom component not to mention the additional bonuses such as MakeScreenshot . So to cut to the chase Is it possible to call the DWM API from a Hydra Plugin and or output a DWM Thumbnail to a Firemonkey surface .. . .. . The code used in my Hydra Plugin is identical to that which is used in the linked example http : www.delphigeist.com 2011 01 01 archive.html and the code used in my host application s is based upon the simple example on the Remobject Youtube Channel http : www.youtube.com watch v 1ADYE5EdIKQ . Comment : DWM works fine in a DLL . Why are you hiding the code from us Comment : You ve taken a very complicated route to get here Hydra DLLs Host apps and plugins Also I don t follow your logic for why you concluded it s an issue with running the DWM code from a DLL especially since it failed from a simple FMX app in the first place . Next time ask a SO question when you get to the first point ie DWMRegisterThumbnail failing for your FMX app : Comment : It wasn t a case of hiding the code it s just that I didn t want to quote what was in the source I linked and have a wall of text in addition to my question which is already pretty long . I concluded it was a DLL issue simply because I couldn t get it working from either a VCL or FMX host . It was probably a case of me incorrectly moving the code to said DLL and relying entirely on that and so an honest mistake on my part . .. . Answer : Without source code I will guess that you are not passing the proper windows handle to the DwmRegisterThumbnail http : msdn.microsoft.com en-us library windows desktop aa969521 28v vs.85 29.aspx function . you can use the FmxHandleToHWND http : docwiki.embarcadero.com Libraries XE3 en FMX.Platform.Win.FmxHandleToHWND function to convert the FMX Form handle to the Windows Handle .

Comment : I must be missing something because the answer that jumps out at me is Use 254 for the alpha value . Do you really need that extra 1 256th opacity Comment : What happens if you use ExtTextOut instead of FillRectangle That is the normal way to draw rectangles in GDI not sure about GDI+ . Comment : What @Tergiver is referring to is that ExtTextOut has been used as a performance boost . It along with PatBlt was faster than FillRect . It doesn t require creation and management of a brush . .. . Answer : Do you want a stupid solution Here you get a stupid solution . At least it s just one line of code . And causing a small but ignorable side effect . .. . .. . Assumption .. . .. . When drawing solid right angle rectangles GDI+ tends to speed things up by drawing them in a faster method than drawing other stuff . This technique is called bitbliting . That is actually pretty clever since it is the fastest way to draw rectangles on a surface . However the rectangles to be drawn must fulfill the rule that they are right angled . This clever optimization was done before there was DWM Aero Glass and all the new fancy stuff . Internally bitblitting just copies the RGBA color data of pixels from one memory area to another so to say from your drawing on your window . Sadly enough the RGB format it writes is incompatible with glass areas resulting in the weird transparency effects you observed . Solution .. . .. . So here comes a twist . GDI+ can respect a transformation matrix with which every drawing can be scaled skewed rotated or whatever . If we apply such a matrix the rule that rectangles are right angled anymore is not guaranteed anymore . So GDI+ will stop bitblitting these and draw them in a fashion similar to the ellipses . But we also don t want to skew scale or rotate our drawing . We simply apply the smallest transformation possible : We create a transformation matrix which moves every drawing down one pixel : .. . .. . Now bitblitting is off rectangles are solid violets are blue . If there would be just an easier way to control that especially one not moving the drawings Thus said if you want to draw on the first pixel row use -1 as a Y coordinate . You can decide if this really is a solution for you or just ignore it .", "Question : this is my first post on this website .. . .. . Anyway I recently started trying to make a win32 app and its been going well so far . Then I wanted to add aero to my app as in not just the borders . So I looked it up online and one tutorial said I have to include dwmapi.h . This is in the Windows SDK . I don t know how to add this to Code : : Blocks . By the way I am using MinGW as my compiler . Also I tried using the MSVC 10 VS2010 compiler in Code : : Blocks but I got a bunch of errors when I tried to use it relating to the compilers linkers not being found . Any help would be great . .. . Answer : Unless you want to do custom drawing of controls and theme interfaces all you need to do to support the visual themes is to add the appropriate manifest http : msdn.microsoft.com en-us library windows desktop bb773175 28v vs.85 29.aspx . If you want to extend Aero Glass into your client area look at DwmExtendFrameIntoClientArea http : msdn.microsoft.com en-us library windows desktop aa969512 28v vs.85 29.aspx and family . There are various articles and tutorials online about how to use it http : msdn.microsoft.com en-us magazine cc163435.aspx . I don t know specifics of using it with Code : : Blocks though .

But the SVN of Code : : Blocks had a preset for me to set up the SDK which worked .", "Question : I have built a .dll under WinXP that claims it can t find DWMAPI.DLL when it s loaded . The problem is that this DLL is a Vista DLL and this a known issue for XP users that have IE7 installed . The recommendation is to uninstall IE7 or repair the .NET Framework via Add Remove programs . I did the repair and nothing changed . I m not about to uninstall IE7 since there must be a better solution that s not the equivalent of reinstall windows . I ve read bad things about people who attempted to uninstall IE7 so I m reluctant to go that route . I am using C++ under Visual Studio 2003 7.1 . I don t see an option where I may have forced delay loading at application launch . I just used default settings when I created the DLL project . I did just now find an interesting option Linker- Input- Delay Loaded DLLs so I put DWMAPI.DLL in there to force it to be delay-loaded . However I get this when linking : .. . .. . . . and it of course didn t change a thing when trying to load my DLL . For the heck of it I added the whole tree of DLLs that lead to DWMAPI.DLL and I get the same message . For the record it s foundation.dll- shell32.dll- shdocvw.dll- mshtml.dll- ieframe.dll- dwmapi.dll . To be more specific about what I m doing I am writing a Maya plugin and get the always-helpful text in the script editor : .. . .. . I used Dependency Walker to initially track down the problem and that s what lead me to DWMAPI.DLL . These are the message depends gives me and DWMAPI.DLL is the only thing that has a yellow question mark next to it : .. . .. . Gerald is right . Maya is in fact using a different PATH than the Dependency Walker . My plug-in loads another DLL for image-processing that lives in the Maya plug-ins directory and depends found it with no problem but Maya didn t . I had to add plug-ins to the PATH in Maya.env . Seeing as this problem wasn t related to DWMAPI.DLL after all but DWMAPI is a common problem I ll post the best link I found about the DWMAPI issue on Novell s website here http : www.novell.com communities node 4372 handling-dwmapidll-dependency . Basically most programs will have this warning in depends.exe but if there is a delay-load icon next to it and you are sure that the program won t directly or indirectly call DWMAPI then it s fine . The problem is elsewhere . If the delay-load icon isn t present then you have to look at the DELAY and DELAYLOAD options in Visual Studio . The fact that depends gave me a warning and not an error was a clue to the fact that DWMAPI is not being loaded automatically . Comment : I hit this problem on one of our Windows 2003 servers . It s just a bloody console app and yet it or some other dependency claims to want dwmapi.dll as well . I d love to see a definitive answer to this . +1 . Comment : I think a lot of the views are from Google drive-bys . Just searching on dwmapi.dll has this as the 2nd result . .. . Answer : Try changing your setting in C C++- Code Generation- Runtime Library to Multi-Threaded rather than Multi-Threaded DLL . Comment : this worked for me - thanks" ] }

I need to perform this task many times so a script based solution would be best . So far i tried to play around with the batch mode of GIMP but failed miserably . .. . Answer : Instead of script-fu which uses Scheme I d recommend using the GIMP-Python binding for this since it is far easier to manipulate files and listings . If you check filters- Python- Console you will b dropped into an interactive mode - at the bottom of it there will be a Browse button which lets you select any of GIMP s procedures in its API and paste it directly in this console . There is as an API call to load a file as a layer - pdb.gimp file load layer - .. . .. . this however brings the image to memory but do not add it to the image - you have to call pdb.gimp image insert layer afterwards .. . .. .

Answer : First : The gimp and gimp-fu module only work when the Python script runs as a plug-in from within GIMP . I don t know what you are calling external file - but the entry-point has always to be a plug-in script . It can them import other Python modules as any normal program . Second : GIMP plug-ins runs are Python 2.x 2.7 in these days - and therefore any declared class should inherit from object - declaring a class without inheriting from object as you do will only bring you unexpected problems - although that may not be your problem right now . The class declaration looks alright but your example on calling it does not - Line.draw background seems to indicate you are trying to call the method on the class itself not on an instance of your line class .", "Question : What I want to do is to open gimp from a python program with subprocess.Popen perhaps and in the same time gimp will start with a python script that will open an image and add a layer.. .

Answer : Ok I finally got it working . I used the GIMP Python scripting http : www.gimp.org docs python index.html to create a gimp plugin which can do a tonne of stuff including the layers you mentioned . Then you can just run gimp from the command-line passing arguments to the python gimp script . The article Using Python-Fu in Gimp Batch Mode http : www.exp-media.com content extending-gimp-python-python-fu-plugins-part-4 was an excellent resource for learning how to call gimp plugins from the command-line .

We need to import the gimpfu module to get the examples to work . Where can we get the installer of PyGIMP on Windows It seems the project is dead and the links are broken . .. . Answer : PyGIMP is part of GIMP GNU Image Manipulation Program and can only work in together with it . For Linux distributions it is often found in a different package - but its code lies inside the GIMP code source and on Windows it is installed alongside GIMP .

These should be : .. . .. . Python 2.5 2.6 or 2.7 Python-gtk Pycairo .. . .. . And finally GIMP itself . Them you can t just use pygimp as a standalone Python module - it has to be launched from within GIMP to be able to use the program libraries and code .

Also I found some of the procedures I needed on this question http : stackoverflow.com questions 20549908 python-fu-select-copy-paste . Also one of my previous questions http : stackoverflow.com questions 33402897 where-can-i-select-my-personal-plugins-in-gimp may help as a reference on how to start making custom plug-ins for gimp . What keeps me stuck .. . .. . I m not sure if the cause is a gimp s bug or my code is wrongly implemented . Due to some of the code posted on the answer to the linked question http : stackoverflow.com questions 20549908 python-fu-select-copy-paste I am wondering if I am overkilling the available memory after all I didn t know that I had to destroy the objects with an specific procedure call until I found out on that answer . What happens if I don t delete them I wonder . Will they persist in RAM until I close GIMP or will they generate persistent files that will flood the GIMP system Honestly I have no idea about the consequences of ignoring this issue . .. . Answer : I fixed it by switching the floating layer to a new Layer instance before executing those two functions . So I make the following combination : .. . .. . The problem seems to be that after executing some procedures over the layer it becomes None it s like if it was automatically removed from memory.. . . This solution allows me to execute 2 or 3 more operations.. . It s not a complete solution . I ll keep researching Comment : It sees you didn t pay enough attention on the @Emil s answer : These procedrues you are calling do not return a resulting layer They transform the layer internally . Just stop prefixing your calls with fixed layer 0 the first layer you reference at te beggining of your script remains a valid reference .

But the plugin woun t show up in gimp menu I m using gimp 2.8 . Gave the file chmod a+x rights . Might the file location be a problem : .gimp-2.8 plug-ins src resize.py The src is because of eclipse . .. . Answer : If your script has any syntax errors it won t show up in the menu at all - the above code does have a syntax-error on the very first line of code from gimpfu import missing a space before the .. . .. . One easy way to check for syntax errors is to try to run the script as a stand alone it will fail when it can t find the gimpfu module outside GIMP but by that time the syntax is parsed - another way is to use a lint utility like pyflakes to check the syntax . Other run-time errors that your script might contain should appear in a pop-up window when running it from GIMP - at that stage you can only update your script and retry it from the menus . If you change the input or output parameters from your script though you have to restart GIMP . And yes the file location is a problem - you must put your code in a directory specified for Plug-ins in GIMP s preferences - by default these are .gimp-2.8 plug-ins or usr lib 64 gimp 2.0 plug-ins - with no src - if your IDE does not let you specify where to put your files you have to copy them there yourself or add the src dirs in GIMP preferences .

What I want to know is how to tell why the plugin doesn t load . .. . Answer : Paraphrasing the original post : I wrote a Python GIMP plugin and installed it in the proper place but it doesn t appear in GIMP s Filter menu so how do I debug it The most common cause is that you didn t give execute permission on the plugin s source .py file when you copied it to the proper place . It s a known quirk of GIMP that it won t read Python plugin source that doesn t have execute permission . Another question might be : my plugin appears in the GIMP Filter menu but it silently doesn t work as I expect how do I debug it You can either start GIMP in a console a terminal so that any debugging print from your plugin goes to the console or use Filters Python-Fu Console as suggested in another answer . If your plugin crashes the GIMP GUI will show you the traceback or it will appear in a console you started GIMP in . Another question might be : can I debug Python scripts that import PyGimp modules most commonly gimpfu which is an omnibus module that imports other PyGimp modules . For example you have a Python module for use by a GIMP Python plugin and you want to test portions of it say doctest it without starting GIMP . You might be able to install PyGimp into the Python directories by the standard : download PyGimp .configure make make install . I haven t tried that and could not easily find a downloadable source package for PyGimp . Usually the PyGimp modules are installed with GIMP and not installed in the Python directories GIMP just futzes with PYTHON PATH when it starts a Python interpreter so that the PyGimp modules are found Or in your environment of the shell or your IDE you could change PYTHON PATH so that it includes the subdirectory of your GIMP installation that holds the PyGimp modules .", "Question : I ve been at Gimp : python script not showing in menu http : stackoverflow.com questions 17334993 gimp-python-script-not-showing-in-menu and it didn t help me .

When I search in Gimp PDB I can find gimp-vectors-export-to-file so what is the problem How should I call this procedure .. . Answer : You are almost there - the pdb module is just exposed at module level with the from gimpfu import so no need to do gimp.pdb . procname - just pdb . procname it would work though . But what is really causing your error is the procedure is actually called gimp vectors export to file - and not vectors export to file - .. . .. . You should be calling it as : .. . .. . Also note that for most PDB calls requiring integer identifiers of image items you should pass an apropriate Python object representing that item instead . The Vectors object for saving individual Vectors is obtained by calling other PDB functions . For saving all vectors instead of the 0 listed in the function description pass None .

That is : repeat the file path on the parameter you are passing 0 . Comment : Sorry but trying pdb.gimp vectors export to file img C : Users Public Documents output.svg C : Users Public Documents output.svg still doesn t work . Also according to pdb documentation the function vectors export to file doesn t take a raw file in parameter . The solution must be very simple but I am still stuck . Comment : Sorry again -- It is not expected that any PDB call from Python will take raw int identifiers as parameters . In the case of calls involving vectors you should pass a full Vectors object which you obtain by using calls like pdb.gimp image get active vectors . In this case for saving all vectors instead of 0 pass it None as the third parameter .

Answer : GIMP plug-ins can only be run from inside GIMP itself - they won t work if they are started by an external debugging system from outside GIMP . I don t know this rpdb2 tool - but it suggests it is possible to attach to the running process at least the one rpdb I know of does - so had you tried starting your script from within GIMP and attaching the debugger later The error at the import step as you show it is due to not running from inside GIMP Comment : Yes I know that GIMP plug-ins can only run from inside GIMP itself . My plug-in is started from GIMP and then later the external debugger is attached to the process . The Winpdb debugger runs outside GIMP and uses another pythonw.exe in a different folder this can be the cause of the error Thank you Comment : Certainly it is . The error message tells exactly that : Wire protocol not initialized is a way to tell it cannot talk to GIMP . Keep in mind that if you can t setup debugging you can make PDB and other calls from GIMP s interactive Python console - that is how I find out the exact semantics of the various calls .", "Question : I need to develop a plugin for GIMP and would like to stay with PyCharm for Python editing etc .

Comment : Sorry busy week.. . The code runs just fine in GIMP . No issues there . It really is a question about setting up PyCharm so it can resolve these symbols . I searched the entire GIMP installation tree C : Program Files GIMP 2 and the above-mentioned symbol names are not found . This probably means they are part of a C library that has been compiled . Not sure it is possible to provide PyCharm with what it needs to know about these symbols without polluting the code with unnecessary band-aids . Again the code is correct and my plugin runs perfectly under GIMP . .. . Answer : As you find this variables are part of .pyd files dll files https : docs.python.org 2 faq windows.html is-a-pyd-file-the-same-as-a-dll for Python . PyCharm can t get signatures for content of this files . For Python builtins like abs all any etc . PyCharm has it s own .py files that uses only for signatures and docs . You can see it if you ll click on some of this funcs and go to it s declaration : .. . .. . enter image description here http : i.stack.imgur.com aVxSC.png .. . .. . PyCharm will open builtins.py file in it s folder with following content : .. . .. . As you see functions are defined and documented but have no implementation because their implementation created with C and placed somewhere in binary file . Pycharm can t provide such wrapper for every library . Usually people who created .pyd files provide their .py wrappers for example PyQt module : no native python implementation just signatures . Looks like Gimp doesn t have such wrapper for some of variables . Only way I see is to create some sort of own wrapper manually . For example create gimpfu signatures.py with following content : .. . .. . And import it while you re creating plugin : .. . .. . Not elegant but better then nothing . .. . .. . .. . One more note about gimpfu.py s path . If I understand correctly you just added this path to project . It may work but correct way is to add it to project s PYTHONPATH in project preferences . See this link http : stackoverflow.com a 24766898 1113207 for detailed manual . Comment : Thanks for this . I ll go through it in detail tomorrow . I was afraid the only way to approach this might be an undesirable artificial import . Comment : If this is something GIMP should provide and someone would contribute it preferably in a way that is updated during a build then we d certainly accept this into GIMP . Comment : The answer given isn t exactly the right answer but I ll award the bounty nonetheless . Comment : @MichaelSchumacher perhaps a connection between you and the folks at JetBrains authors of PyCharm might facilitate this I am not in a position to contribute to GIMP working 16 hour days already but perhaps JetBrains might have interest in having PyCharm work seamlessly for plugin development ." ] }

Once the font family s weights are mapped onto the CSS scale missing weights are selected as follows : .. . .. . If the desired weight is less than 400 weights below the desired weight are checked in descending order followed by weights above the desired weight in ascending order until a match is found . If the desired weight is greater than 500 weights above desired weight are checked in ascending order followed by weights below the desired weight in descending order until a match is found . If the desired weight is 400 500 is checked first and then the rule for desired weights less than 400 is used . If the desired weight is 500 400 is checked first and then the rule for desired weights less than 400 is used . Now it may seem like jargon but for your case you just need to read the last point of it . If the desired weight is 500 400 is checked first and then the rule for desired weights less than 400 is used . So ultimately it will find if the base font is used if not it will find anything lower than the base font and then if nothing is still not found it will try to find anything higher than it . .. . .. . Rendering when bold .. . .. . The normal font-weight for bold is 700 . This does not chang once you start going up in font weights . If you want the font-weight of a piece of text that needs to be bolder than normal text you will need to use bolder or the alternative lighter as the space between the base font weight and the bolder must always be greater unless it is at it s limit . Below is a table of what the specific meaning of bolder and lighter is . Base - bolder - lighter .. . .. . 100 --- 400 --- 100 .. . .. . 200 --- 400 --- 100 .. . .. . 300 --- 400 --- 100 .. . .. . 400 --- 700 --- 100 .. . .. . 500 --- 700 --- 100 .. . .. . 600 --- 900 --- 400 .. . .. . 700 --- 900 --- 400 .. . .. . 800 --- 900 --- 700 .. . .. . 900 --- 900 --- 700 .. . .. . Ultimately all this information can be found in the W3.org spec . font-weight - Fonts W3.org https : www.w3.org TR CSS21 fonts.html propdef-font-weight Comment : Thank you for the docs link it clarifies as well as your answer a lot . I was not clear with my question : I was specifically wondering how the missing weights are computed and if this imples a loss of quality or not when there is nothing to fill the holes per the docs . Comment : Hopefully the second section Rendering when weight isn t loaded explains the procedure the browser goes through to replace missing weights . Comment : The second part was very clear about bolding . What I am wondering is if I have only the base font which is what is loaded I belive via a bare @import url https : fonts.googleapis.com css family Roboto then the other weights will need to be computed . Is this computation lossless quality-wise and in that case it is not obligatory to load other-than-base weights - or is it approximate and specific weights need to be loaded in order to render the font perfectly Comment : @WoJ i believe it just darkens the font more but as the spec states There is no guarantee that there will be a darker face for each of the font-weight values", "Question : If I load a google font that comes with 400 and 700 weights but in my CSS I use font-weight : 550 what does the browser do .. . Answer : According to MDN https : developer.mozilla.org en-US docs Web CSS font-weight and W3.org http : www.w3.org TR CSS2 fonts.html propdef-font-weight : .. . .. . If the exact weight given is unavailable then the following heuristic is used to determine the weight actually rendered : .. . .. . If a weight greater than 500 is given the closest available darker weight is used or if there is none the closest available lighter weight . If a weight less than 400 is given the closest available lighter weight is used or if there is none the closest available darker weight . If a weight of exactly 400 is given then 500 is used . If 500 is not available then the heuristic for font weights less than 500 is used . If a weight of exactly 500 is given then 400 is used . If 400 is not available then the heuristic for font weights less than 400 is used . .. . This means that for fonts that provide only normal and bold 100-500 are normal and 600-900 are bold . Also : .. . .. . There is no guarantee that there will be a darker face for each of the font-weight values for example some fonts may have only a normal and a bold face while others may have eight face weights . There is no guarantee on how a UA will map font faces within a family to weight values . The only guarantee is that a face of a given value will be no less dark than the faces of lighter values .", "Question : I usually download fonts from Google via @import url https : fonts.googleapis.com css family Roboto and then use them to tweak various elements h1 h2 .. . .. . .. . How is the font rendering calculated when : .. . .. . the correct weight 500 in the case above has not been loaded via @import url https : fonts.googleapis.com css family Roboto : 500 It is extrapolated from a base version of the font with better or worse results Or calculated and in that case preloading 500 just helps performance wise but does not impact the visual aspect of a font bold is used Is bold a shortcut for a specific numeric weight Or does a font defines itself what bold means in its case it would be a specific numerical weight I guess .. . Answer : Weight defines from thin to thick characters . 400 is the same as normal and 700 is the same as bold .. . .. . As far as I m aware the browser will set the font to the default set in CSS if one is set or the computers default which I think is Helvetica on Mac and on PC I think it s Arial . The font weight would still be applied .", "Question : null .. . Answer : I m using the @font-face rule to display the VAG Rounded font on my website . It has four variations : thin light bold and black . So I tried to set light as normal thin as lighter bold as bold and black as bolder .

Is there a way i can initialize SlidingViewController in Main view controller and by using slidingViewController.leftViewController open the slide menu when the menu button is tapped .

Thanks in advance .. . Answer : It s very difficult to diagnose issues like this without seeing sample code . What I will say having worked with ECSlidingViewController in the past is that you should be checking for login credentials in your AppDelegate . The idea is that by keeping your LoginViewController outside of the navigation controller tree for ECSlidingViewController you don t have to present that navigation controller until you ve successfully completed the login flow .

Is it possible to append another column business ID to one of its table in such a way that it does not cause problems in QuickFix J s internal message logging If it is possible kindly mention the procedure to do it too . Comment : read able content .. . Answer : The solution is to create your own Logger and LoggerFactory similar to the ones provided by QuickFix J . You can create a Logger by implementing the quickfix.Log interface and a LoggerFactory by implementing the quickfix.LogFactory interface . The easiest approach would be to use the private AbstractLog from QuickFix J . Creating the Log class : .. . .. . 1 . Copy the AbstractLog https : github.com quickfix-j quickfixj blob master quickfixj-core src main java quickfix AbstractLog.java class as it is from QuickFix J s source and include it in your project . 2 . Create a class which extends the AbstractLog class and implement all the abstract methods . 3 . Create member variables for any extra field you want to append to the logs e.g . business ID and provide a constructor which takes is as an argument and sets its value . 4 . The logIncoming and logOutgoing methods take a String parameter . This is the data you want to log . At this point you can append your own fields added in point 3 to the logs . You can format the log as you wish and you are free to use any method of output i.e . Console database etc . as you will have to implement it yourself . Creating the LoggerFactory : .. . .. . 1 . Create a LoggerFactory that implements the quickfix.LogFactory interface . .. . 2 . In the create method create and return the instance of the Logger you created before using the constructor you require . .. . 3 . The values that you need to be passed to the constructor can be kept as member variables of the LoggerFactory and set in LoggerFactory s constructor . You have a custom Logger now and can use it as QuickFix J s own loggers are used and QuickFix J will automatically log using your logger . Taking a look at QuickFix J s own Logger and LoggerFactory implementations for help would be a good idea . e.g . The Logger that Logs on Console : ScreenLog https : github.com quickfix-j quickfixj blob master quickfixj-core src main java quickfix ScreenLog.java ScreenLogFactory https : github.com quickfix-j quickfixj blob master quickfixj-core src main java quickfix ScreenLogFactory.java .. . .. .

Answer : First of by looking at the Javadoc http : www.quickfixj.org quickfixj javadoc 1.5.3 for QuickFIX J one could argue it is kind of lacking the information needed for the methods you choose between . My recommendation for you is to look at the source code https : github.com quickfix-j quickfixj blob master quickfixj-core src main java quickfix Session.java for this project and compare the methods one of the benefits of open-source software .

Now the better way to handle incoming messages as mentioned before is through a MessageCracker . You would eg extend the class that implements quickfix.Application with quickfix.MessageCracker .

These application are in the quickfix examples directory . They are not meant to demonstrate good application-design or meant to be used in a real production system .

Answer : Why are you doing the message processing in the wrong place If you check what is recommended by Quickfix you will see they recommend message processing happens in onMessage which you might not have implemented . And there should only exist a message cracker in fromApp method . Or else your fromApp method is going to be a hotchpotch of code and the next person handling your code is not going to be a happy soul .

Answer : In FIX the order of tags in the top-level body does not matter . The various QuickFIX engines internal representations of Message objects ignore the top-level tag order because there is no benefit to storing it . When the message is converted to a string it orders them by numerical tag order . It doesn t change the message in any meaningful way according to FIX . .. . .. . Order is preserved inside of repeating groups because FIX does mandate that the ordering is meaningful inside of groups . What can I do to keep the groups in the order I want For QuickFIX the answer is : You can t . .. . .. . If that is a really big problem for your needs there s no reason it should be then I guess you ll have to explore other FIX engine options . Comment : Thx Grant.. . So why is the ordering swapped at all Comment : Because the Message class stores the top-level body fields in a HashMap I think that is keyed by tag . Hashes do not preserve order .

Answer : Instead of creating a message from scratch you should be using the predefined messages in QuickFIX J . In your case I would start looking at quickfix.fix44.NewOrderList http : www.quickfixj.org quickfixj javadoc 1.5.0 documentation for 1.5.x latest QuickFIX J version is 1.6.x though . By using this class a whole lot of fields will be filled in for you in the header and footer part of the message BeginString BodyLength MsgType CheckSum .. . . You then only need to concern yourself mostly with the main part ie body of the message . For the repeating group there are helper classes available to set that information in the message . Eg for NewOrderList.NoOrders http : www.quickfixj.org quickfixj javadoc 1.5.0 : Comment : Yes I know that I can use predefined message . But I like to control what happens and then use the basic Message . And because my counterparty sent me spec about what they attend to receive so by using predefined message I m not sure that all required by counterparty fields will be set . But ideally you re right . I ve post my solution above . Comment : @Alexxx I saw that always good that you can solve your own problems . The minium conditionally required fields are governed by the dictionary though set by configuration options . These reflect what the FIX standard requires . The counterparty can always ask for additional required fields but there s no difference in that regard between using manual messages and predefined messages .", "Question : I have implemented a QuickFIX J http : www.quickfixj.org application the J stands for Java . Now I consider how to set up fixed test cases . I am a little bit familiar with JUnit but I don t know if it s the right one for that issue because QuickFIX J has callbacks fromApp -method of the Application class for example . Maybe there is someone out there who has had the same problem and found a nice solution for that issue . Comment : JUnit works just fine . I used it when I set up test cases to test messages and for coverage . .. . Answer : If you re testing the responses of a QuickFix application then you re really into integration-testing rather than unit-testing . So as you ve already written one QuickfixJ application you could write a testing application that connects to it . So if your application is a Fix acceptor write one that is an initiator . Now you can send messages from your test application to your real application . Any responses from your real application will call onMessage in your test application . You can capture these callbacks and then you can verify that they match certain patterns e.g . the application returns the same Client order id that the test sent . You can certainly use JUnit for this .", "Question : I wanted to clarify a behavior of QuickFIX J FIX 4.2 under the following scenario . There are two parties involved in this QuickFIX J communication : .. . .. . 1 . A client initiator called I . 2 . Our firm s acceptor program called A . When I logs onto A they exchange FIX messages with tag 35 A . Once a connection is established I starts to submit orders . There may be a point however where I disconnects unexpectedly at which point A decides to send cancels for all of the open orders of I this is valid because A has no idea why I failed or when I would come back alive . Note that this entire cancel-on-disconnect procedure is initiated and handled by A alone - it gets initiated from A s onLogout .. . method and handled by its normal order management mechanisms . A single 35 F message gets generated for each of the open orders of I and an ExecutionReport 35 8 gets generated on each successful cancel . When I comes back alive these ExecutionReport s must be delivered to I somehow so that it becomes aware all its previous orders have been cancelled . I had an impression that QuickFIX J s message-queue implementation handles this without an application-level aid . All QuickFIX messages are ensured for delivery to counter-parties http : permalink.gmane.org gmane.comp.finance.quickfix.devel 169 . Contrary to my understanding however no ExecutionReport s were not shown in A s QuickFIX logs or delivered to I when I reconnected resulting I to be unaware that its previous orders have been cancelled . I noticed that logging does not occur because of the following source code of the sendRaw Message message int num method of Session in QuickFIX J : .. . .. . The session was not logged on while ExecutionReport messages were being generated for cancels initiated by I s disconnect and therefore it never hit the send messageString and no logging happened . I believe no message got queued based on the fact that I does not receive any messages when it comes back alive for the same reason . Our firm made many implementations based on the belief that QuickFIX J guarantees all messages to be delivered without a loss but my observation on the scenario above speaks otherwise . How is QuickFIX J s message-queue expected to behave in this scenario when a session is not logged on Should it queue messages regardless waiting to be sent once the session becomes available again in the future or stop queuing for the duration while the session is down Comment : You may want to try the QF j mailing list for this one if nobody here answers . Comment : There may be a point however where I disconnects unexpectedly at which point A decides to send cancels for all of the open orders of I .. . . That sounds terrible . Simply because there is a network problem eg for 15 minutes you cancel all orders Sorry to say so but that sounds ridiculous . What rationale is there behind that What real business explanation is there for that requirement Comment : @GrantBirchmeier Thanks for the feedback . We actually confirmed that 35 8 and 150 4 was coming to the initiator from the acceptor upon reconnect . I somehow failed to detect that . Comment : @TT . I believe the rationale is that the practice reduces the risk of executing orders that are no longer wanted - during a network issue client might try to cancel or replace a currently-open order and that obviously cannot go through . Of course cancelling all open orders in case of unexpected failure is not ideal for everyone but it does provide a guard against some scenarios . .. . Answer : Just at the end of the private boolean sendRaw Message message int num method there is this code : .. . .. . The state.set msgSeqNum messageString will call messageStore.set sequence message which actually stores the message for later delivery if the session is not connected . As far as I know all messages will be queued until the session successfully logs on .", "Question : I am relatively new to FIX and this is my first time trying to connect .

Answer : Importing the second example http : www.dailyfx.com forex forum fix-api-support 64877-quickfix-java-example.html as-is instead of trying to implement into my own Eclipse project worked .

Maybe anyone can help me.. . Thanks for your effort .. . Answer : One way to do this is to customize the Data Dictionary FIX4.4.xml and replace the fields in it that can sometimes be in FIX 5.0 format . Eg by copying them from FIX5.0.xml and placing them in the proper messages in FIX4.4.xml . From the QuickFIX J user-manual http : www.quickfixj.org quickfixj usermanual 1.5.3 usage codegen.html : .. . .. . The simplest customization is to just modify one or more data dictionaries e.g . FIX44.xml and rebuild QFJ . This allows you to add custom-fields define new messages not included in the specification change whether fields are required or optional and so on . Afterwards rebuild QuickFIX J to reflect these changes . EDIT : Following is for version 1.5.x .. . .. . Check the QuickFIX J user FAQ http : www.quickfixj.org confluence display qfj User+FAQ on how to rebuild QuickFIX J EDIT : version 1.5.x : .. . .. . You ll need ant installed . .. . QF J generates the source from the DDs in core src main resources . Make a back up of the one you re going to alter and then alter it however you need to . .. . Then rebuild as follows : .. . .. . 1 . ant jar .. . 2 . You will be prompted for a release number this just determines the suffix given to the jar names . Enter whatever you want . 3 . Wait for build to finish .. . 4 . Find your brand-new QF J jars in core target .. . .. . A little further in the FAQ how do I rebuild QF J the call to ANT is more specific : .. . .. . The version argument is just a filename suffix . The skip.jalopy argument is optional and will skip some time-consuming doc generation . .. . ant version SOME STRING -Dskip.jalopy true clean jar .. . .. . EDIT : Following is for version 1.6.x .. . .. . For version 1.6.0 building is done with Maven . If you are building the code from the command-line you ll need to download and install Maven version 3.2.5 or newer . If you are building from an IDE Maven is usually included . Building from source requires Java 6+ . .. . 1 . Check out the code from GitHub . See the instructions at GitHub for more details on cloning the repository . 2 . Change directory to the top-level directory of the checked out code . You should see a pom.xml file . 3 . Run mvn package to build the QuickFIX J and examples jar files . This will also generate all the FIX message-related code for the various FIX versions . 4 . There is an option for the code generator to use BigDecimal instead of double for fields like price and quantity . To enable this feature pass a -Dgenerator.decimal option on the command-line when running the generate.code target . .. . There are various command-line switches you can pass to ant to modify the produced behavior : .. . .. .

One can also create and send a logout message explicitly . How is that different from the other two Comment : From which API Interface do you get these logout and generateLogout methods Show some code . .. . Answer : The logout method is the way to go . It will-change the enabled flag which will trigger the public void next method called by a timer . This will use the generateLogout method to send the correct FixMessage 35 5 . The generateLogout methods are all private except the one with no parameters which where changed to public with a changeset with no reason so I guess this happens unexpected since it is just a helper method for creating the message .

I decided on AngularStrap as it provided support for Bootstrap-Select which I wasn t sure was the same for AngularUI . The tabs example http : mgcrea.github.io angular-strap tab only covered static html though . Is there any way via AngularStrap or AngularJS to load html fragments dynamically so that it is only called when the tab is clicked My html fragments need to execute javascript as well . My reason for doing so is two-fold . First is that each tab contains quite a lot of content and I do not wish to load all the tabs at once which will slow down the loading . The second reason is that I prefer a more modular approach to my source code and not put everything on the same html file . .. . Answer : You can use the ng-include http : docs.angularjs.org api ng.directive 3angInclude directive to load html fragments .

My goal is to create a similar widget HTML select element but with custom templates for each element . The widget works fine . but using Batarang discovered that whenever the user displays the dropdown child scopes are created and are never destroyed . Thus each time the dropdown is displayed more and more child scopes are created . I need to understand how to do a proper cleaning of the children scopes .

Answer : I believe this is actually an issue of tooltip service as I m able to see the same thing happens in the dropdown demo http : mgcrea.github.io angular-strap dropdowns of AngularStrap itself . When showing the dropdown the tooltip.show will clone the dropdown template and link with the same scope everytime see tooltip.js L198 https : github.com mgcrea angular-strap blob v2.0.5 src tooltip tooltip.js L198 .. . .. . And in tooltip.hide there is no code that destroy scopes created inside the template e.g . by ng-repeat thus the problem occur .

I m trying to watch the values in this select box and run a search any time the values change . My select button looks like this . The problem is that scope.subject list never gets populated . The selection seems to work fine and the ui all looks good but ng-model never gets populated with anything . In my controller I initialize scope.subject list to an empty array and then have a watch function checking to see when it changes . Nothing ever gets fired . I even wrote a little function to print out the value of scope.subject list ever second and it s always empty . Any thoughts as to what s going on I had this working at one point so I m either doing something silly or a recent update broke things . Update .. . .. . This seems to be a scope inheritance issue . I ve got all kinds of scopes going on which could be part of the problem . However I was able to get this working by doing everything on the rootScope . So.. . .. . .. . and .. . .. . I m sure this isn t the best way to do this but I can t figure out what s wrong with my scopes . Comment : Can you replicate it in a plunkr please It could be something else in your code as that looks the same as the example on AngularStrap . If it s an isolation issue you could try putting subject list inside an object and referencing it that way . Comment : I m noticing that I m having the same issue with other select modules like this one http : nya.io nya-bootstrap-select . Seems like no matter what the ng-model isn t getting set . I tried setting up a plunkr but when I tried loading angular-strap it bombed out . I can try with this other module . Comment : Try create it from the Live Demo plunkr off of angular-strap here : mgcrea.github.io angular-strap tooltips selects http : mgcrea.github.io angular-strap tooltips selects click the plunker link next to Live Demo . Then you know that it s got the correct files loaded and should work . Personally I d avoid using modules like the one you linked as it s just a clever wrapper for the jquery plugin which means you have a lot of code bloat . Comment : Ok I ve narrowed it down to some type of scope inheritance issue . If I put everything in the top level scope it all works fine . However when I m a couple levels down something s up . The select actually seems to be working fine . When I put subject list in the view itself it gets updated fine . But in the controller it never changes . Comment : You might be able to get around it via parent.subject list parent references the the parent of the current scope . If you can post up the structure with directives from the ng-controller tag to the bs-select tag there might be something there unless of course it s in a custom directive . If it s a custom directive then if possible remove the scope : .. . option which will stop it from creating a child scope . .. .

Answer : You seem to have already decided that a seperate UI is needed for mobile-devices and I support this . The way the user interacts with these devices is so different that you need to think of them in a specific way . For other screen sizes I think they need to be approached from a users perspective . If the user interacts with the screens in different ways then you need seperate interfaces . However in my experience users tend to look at screens from about 10 upwards as simply bigger or smaller versions of the same thing and so you should treat your UI in the same way . Don t change it dramatically for smaller screens . Instead you need to find a way for it to grow or shrink in such a way that the user feels that they have more space to work in . with the same old UI . Text editors are a prime example of this . The document window grows bigger there is more space for documents to be edited in but the actual interface stays pretty static .", "Question : Scenario : You need to expose the same app on different screens - let s say a standard 15 -17 a portable 10 and a mobile 4 possibly working on different resolutions .

Answer : We are just starting a project where we have a very similar problem . In our case the app will work slightly differently on the different screens more stages and fewer options on the smaller screens for example . What we plan to do is to use the ASP.Net MVC framework and implement a view for each screen-resolution sub app . We will try to keep the rest of the app common to all screen resolutions .

Answer : Mobile Apps for cell phones and other portable devices usually get a hand rolled mobile UI . The 10 - 13 case you re talking about is more in the netbook range . In this case the device UI is similar in most cases to a regular desktop UI so I would go with a liquid-layout and use the same UI . EDIT .. . .. . See the comments for clarification on requirements.. . But considering the smaller interface is going to be a touch interface and the larger interface will not...I d suggest rolling different UIs for each . The UX for the touch version will be much better if special considerations are made regarding touch based concerns . Comment : thanks for your contribution - in my specific case the concern is that as the UI shrinks the UX also is gonna get downscaled to some extent when you move from 13 to 10 I am using a touchscreen and a requirement is for primary input to always come from fingers - not stylus Comment : Does the input requirement hold true for your app running on all screens or only the smaller ones Comment : only for the smaller ones at current stage Comment : Updated my answer for the new requirements .

Answer : In the context of web-applications Jakob Nielsen suggests http : www.useit.com alertbox mobile-2009.html basing his assessment on recent usability tests read linked article for details to design a dedicated UI for mobile-devices .

Because I only want the right column to scroll when the content overflows I ve put left and middle inside a fixed positioned container .wrapper which takes 50 of the page and the other 50 for the right hand column . I ve made the margins as borders with box-sizing . But when I resize the browser the middle column resizes until in disappears and the text on the left and middle column overflows . Any ideas I ve also done this on jquery but I seem to be running into the same resizing problems . Can anyone shed some light on this issue Many thanks Comment : I am unsure what exactly you want the right column to do Comment : Right column is 50 of the total window width and scrolls on content overflow .

The webpage would be small on their screen but would fit on min . How would I make the page expand to 100 or maybe 95 Comment : There is no software in the world that sizes based on monitor inches . You want pixels . Comment : Resizing the browser is a sure-fire way to annoy the CRAP out of your users . I have to use an expense reporting tool that does this to me . Those of us with larger monitors generally don t want or need a window to be maximized . Comment : Geeze people READ the question before posting stupid comments . Comment : Never never never never force a window resize on your visitor . Its ok but IMHO barely ok to lay the page out using fixed sizes that would require the user to resize the window herself but even that is a sure way to anger a visitor if it isn t justified by real value added . Comment : Down boy . . regardless of WHY one should be using screen-size in their javascript programming . . some people may still interested in HOW . .. . Answer : I think there s some confusion about whether or not Bob is asking about the actual size of the monitor or the size of the window . Josh Stodola and Rich Bradshaw offered the HTML CSS answer which uses percentages to create a fluid-layout which expands with the window . The following code sums up this technique creating two columns one taking up 80 of the current browser window and the other taking up 20 . The column sizes alter when the user changes the window size . Rudd Zwolinski provided the answer which looks for the user s current resolution . Others have already posted the potential annoyances caused by using this method but I don t know maybe you re making some artistic statement about resolution sizes .

Thank you in advance .. . Answer : I don t think that there is a way to do this . All of the layouts for locomotive are stored in the database and the rendering process is completely separate and different from the rails rendering process . I think the simplest way would just be to copy the application.html into the index layout adding in the necessary liquid blocks . Comment : Thanks Charlie Greene So we should maintain same pages twice like contact page code in rails and as well in locomotive liquid So dont we have any chance to respond to rails from locomotive Comment : I haven t done many app and cms intergrations . We mostly just use the cms but I think that you should be able to just maintain the application layout twice once as the rails app and one as the index page in locomotive and then maintain the pages you want to have access to via the CMS just in locomotive . You may have to do something with the routing to make sure that your rails pages are displayed . Comment : As of now i could make cms work by using layout twice in rails and locomotive .

If you want them to expand and keep left static move those children out . http : jsfiddle.net MhCke Comment : This is not what I want the right will expand on its own if more content is added . Comment : I didn t add some of these classes but I ll remove them and post a jfiddle link Comment : jsfiddle.net Ex4tK http : jsfiddle.net Ex4tK Comment : Thanks for the fiddle . My opinion is still the same especially for a fluid-layout . You can cheat the parent width by setting it s overflow to visible however when you then add 100 as the child s width you are setting it to be the parent s width not the grand-parent s width . Comment : Updated your fiddle . Removed the floats and added positioning as well as overflow : visible to left which will allow the width to cheat the parent . jsfiddle.net Ex4tK 1 http : jsfiddle.net Ex4tK 1" ] }

Answer : I would also suggest running a few virtual machines rather than running multiple versions of Internet Explorer on the same instance of Windows .

IE7 is now Vista only 4179MB vs . 366MB and IE8 is Windows 7 only 2633MB vs . 366MB Comment : @coobird : I went looking for these recently 10 2011 and discovered that MS no longer has Win XP SP3 images with IE7 or IE8 or for what it s worth Vista with IE8 . The only IE7 image they have available now is Vista only 4179MB vs . 366MB the IE8 image is Windows 7 only 2633MB vs . 366MB .

At this moment Lolipop is very buggy so I am assuming that they will fix it asap . I am not aware of any workaround atm .

How can I make PFFacebookUtils v4 use the system Facebook account when available and only fall back to Facebook app when a system account is not available .. . Answer : Opening the Facebook app is the preferred scenario for authenticating with your app according to the SDK . This behavior is defined by Facebook and their SDK and not a Parse issue really . Unless you want to add a whole bunch of custom code to interface with iOS system account directly you d have to live with the app opening and returning to your app . Thats how everyone does it .. .

What do you expect to happen when an app dependency changes it s behavior Check your code for what you are doing whenever the app switches to the Facebook app and back . My hunch is that you are requesting permissions or try to use a permission you have not requested or the like . Consider the Facebook SDK under constant development .

Answer : Is this something that you need to do in real-time and or in production for monitoring Or is this just something that you need for debugging I would suggest just using one of the JVM memory-dump tools or maybe launching your app with the JRockit jvm and doing some live analysis with that . http : www.schierberl.com blog coldfusion-memory-leaks-part-i-profiler-introduction", "Question : I m having an odd intermittent issue with the 404 handler pages on our ColdFusion 10 server . Here s the backstory : .. . .. . 1 . We have been running 2 load-balanced ColdFusion 8 servers for ages without issue . 2 . We have upgraded one of these two servers to ColdFusion 10 in order to soft-launch our ColdFusion 10 upgrade . 3 . I ve installed Update 8 on the CF10 server and have removed and re-added the connectors . 4 . Both servers are running Windows 2008 R2 . I ve read several forum posts stating issues with people getting connection reset issues with their 404 pages but I m not seeing that particular issue . What I am seeing is a hung thread in FusionReactor for the 404.cfm file . Here s an example of the stacktrace taken from one of these hung threads : .. . .. . I ve tried manually killing these threads through FusionReactor but they won t die . The only way to clear the hung threads is to restart the ColdFusion service which I ve had to do at least once a day since I upgraded to ColdFusion 10 . The 404 doesn t do anything special other than run our standard layout custom tag and display a page not found notification . Looking at the thread-dump it appears that ColdFusion has finished doing the processing and completed filling the buffer with output but it s not finishing sending to the browser There s lots of stuff there about closing and finishing but the steps following it have more reads and responses . So I m not sure what might be happening here but it s definitely stalling the completion of our ColdFusion 10 migration . I need to discover exactly what s causing these hung threads . Comment : what happens if you hit the 404 page directly Comment : I ve never seen the problem myself it always renders for me . We have those pages hit 100s 1000s of times a day by bad bots but I see just one or two hung threads a day and it s always on 404.cfm . .. .

Their engineering team has acknowledged the issue but no ETA on an actual fix . Adobe s connector for IIS in CF10 has been quite troublesome for us . You can set a timeout to kill these hanging threads as listed in my workaround which will at least keep you from having to reboot the server daily . Good luck Comment : Perfect .

Answer : As @beloidavisja suggested you should remove the javaagent and agentpath arguments from the jvm config . Those are the arguments required for fusionreactor . After removing the arguments from the config file make sure to restart ColdFusion server . A restart is required for the changes to take effect . Read this http : docs.intergral.com display FR51 Manual+Installation Comment : Though be sure you always make a backup of jvm.config BEFORE making any modifications . Mistakes in the file can prevent the server from starting so you do not want to be caught without a backup copy .

You can switch back to this assuming you didnt make changes to it when FR was installed .", "Question : We ve had a memory problem for a long time . I ve finally tracked down how to replicate the issue but I do not know what is causing it or how to fix it . We have a number of cfc s in a web accessible controller directory that handle for submits and processing . When a cfc is called directly with no method argument the server begins to chew up memory . For instance an URL like http : www.domain.com controller LoginController.cfc will run in the browser until it times out . The CFIDE has been locked down and is not publically accessible .. . .. . so the cfexplorer is not or should not be available . We use FusionReactor to monitor our instances . Our servers are set for 20GB of heap space . On a fresh restart after loading the application memory will cruise around 800MB . With normal traffic memory will fluctuate between 5GB and 10GB with regular garbage-collection . After awhile the server eventually reaches 98 capacity . It tends to run there .. . .. . fine for hours or even days sometimes until some spike in traffic pushes it over and an outofmemory error occurs . Garbage collection recovers no memory and there are no active .. . .. . long running threads reported by FusionReactor . Only a server restart will recovery it . Using FusionReactor which we ve just installed which is how I finally got some insight into this issue I was inspecting the PermGen memory space and found that it accounted for .. . .. . 85 of the heap . This didn t seem right at all . I performed a memory-dump and loaded it into MAP through Eclipse to analyze it . I found that there were 10 objects in memory .. . .. . measuring 1.7GB 1.7x10 is approx 85 of total heap . These objects look like this : .. . .. . So I restarted CF on one of our servers . Checked FusionReactor and saw no memory usage . Then went to a browser and called the cfc first like this : .. . .. . http : www.domain.com controller LoginController.cfc method foo .. . .. . This resulted in the onMissingMethod handler properly kicking and redirecting to the appropriate error page with no server effect . But then calling this : .. . .. . http : www.domain.com controller LoginController.cfc .. . .. . Resulting in a page hang . FusionReactor reports there are no active request even though one is running one which is why we couldn t identify the problem while it was happening . Worse refreshing the memory sees it slowly increase by tenths of a percentage with no reported activity . The timeout on the server is set to 5 minutes . I m assuming that eventually it gets killed and then orphaned at 1.7GB . This didn t bring down the server just spiked the memory where it was now running at a flat 3GB usage where garbage-collection recovers nothing . This seems to explain why over time random calls to these URLs slowly chew up and hold onto memory . Next I called the URL from multiple browser tabs . This spiked the memory almost instantaneously to 98 . FusionReactor now showed two long running requests 10 seconds and climbing even though there were over 15 browser tabs running . Force killing the thread seemed to do nothing . Only a server restart solved the problem . So now I ve identified the issue specifically phantom threads creating huge orphaned-objects in PermGen heap and how to replicate the issue . How or why requests are made directly to the cfc I have no idea . Possibly bots or occasional weird browser behavior . All the huge objects are instances of jrun.servlet.jrpp.ProxyEndpoint . What specifically is causing this issue and how do I fix it . This is CF9.01 Standard on Win2003 Server running Java 1.7.0 25 . Thanks Screenshot of MAP analysis of heap-dump http : i.stack.imgur.com 0ynya.jpg Comment : although not a proper fix could you configure Apache IIS to block log requests to that exact URL As for what s causing your problem I think if your heap s being exhausted it may not be a permgen thing . PermGen objects aren t held on the heap . It may be that there s a reference to the byte array which is still live stopping GC de-allocating it .

Or was it fixed with a hotfix Is this only a CF9 issue Very confusing comment by Nimit Sharma . .. . Answer : Perhaps you could use onCFCRequest http : help.adobe.com en US ColdFusion 9.0 CFMLRef WSe821657cd7d6f83f6daaa733122cf6931bb-8000.html in your Application.cfc to monitor this issue . It would still create the object but you could log the request then the CFABORT should stop the request dead in its tracks . Comment : A workaround like this occurred to me after posting . The interesting thing is that we already do implement oncfcRequest to handle our direct calls to cfcs . After some testing it seems that the method IS NOT being called if there is no method argument . It looks like onRequestStart is hit first . It seems to test the argument.targetPage for a cfc call . If it is a cfc AND method exists is passed onto the oncfcRequest . So your method may work if implemented in onRequestStart . Still working on it but very interesting behavior .", "Question : null .. .

Answer : I know it d represent a big shift in how you do things but I ve always avoided allowing CF to unnecessarily create CFCs . Unless they ve changed how they do things I last played with this versions ago hitting the CFC directly causes a new instance to be created . If you re up for a small test maybe try setting up a simple front-controller delegate .cfm page and moving the CFCs within controller to the application scope . There s certainly more elegant architectures to handle it short of moving to a full-bore framework but you could : .. . .. . Use Application.cfc to set an instance of something like LoginController into the application scope and then use a simple invoke.cfm page that basically expects the name of one of these application-scoped CFCs to invoke along with parameters . Something like just for example s sake : .. . .. . Note that this d cause your controllers to be stateful and thread-safety would need to be considered but should already be anyhow .", "Question : null .. . Answer : This is an extreme longshot but once in a while there is an engineer on here that knows what s going on under the hood . First I know that you can almost always rewrite some code to avoid QoQ for much better performance . However what I m trying to debug is a potential reason that code that uses QoQ would perform so poorly under certain conditions to develop guidelines for future projects . 1 Is there something about the ColdFusion QoQ Java implementation that would cause access to the QoQ system to be single-threaded I saw post on Railo about this https : groups.google.com forum msg railo Fsh-uuwE2ic SetqhPXrbpYJ .. . .. . 2 According to FusionReactor the stack-trace has the request always in the evaluate 90 chance or execution phase 10 chance of the QoQ -- never any other part of the logic surrounding it . That s with it running in a loop with a query param . We have several different features that make use of QoQ in a loop over tens of thousands of iterations to generate a report regardless of that being best practice or not . The only processes that slow down are the ones that use QoQ . They become 10 times as long to complete unless they are kicked off nearly immediately after a server reboot . FusionReactor always has the thread-state at evaluating the QoQ or processing the QoQ . Of note : the Heap and CPU are just fine holding steady at under 20 during the entire duration . All memory spaces look good -- code cache perm etc . I know that running QoQ in a loop is not the way to get it done and should be changed but I m just looking for answers . Is code locked Is it an available thread issue Is there something about evaluating the statement Why would it be fine right after a restart but quickly degrade within hours That s what bugs me -- I d be fine with it taking forever always it s the oddball pattern that has me on stack-overflow . ColdFusion 10 if it helps . Comment : I do not think it is a thread issue . QofQ runs in the request thread like other logic operations . Under the hood it is doing array struct comparisons - usually of strings . One way to optimize is to sort your initial data effectively and make sure you are using the right data type in your QoQ to avoid implicit type conversions like float to string for example . But if you think of a function to compare and extract an array of structs to antother array of structs - it s expensive unless it s very small data sets . sorry . Comment : JT - post some code - maybe we can offer some specific suggestions . Comment : @MarkAKruger I agree it is totally inefficient especially in comparison to building a struct once which is far more efficient for repeated lookups . What I m trying to understand is why this particular logic could slow down over time when other CPU bound logic does not . Code is a simple QoQ straight from the books . There is no datatype issue -- I ve experienced that hell with dates before . Comment : yes - beyond 300 400 rows its not great . sorry . Straight from the books is sometimes a problem though ha . Comment : FYI - I actually like and recommend it in some cases - readible and easy to conceptualize and below a certain threshold works with zero impact .", "Question : We ve had a memory problem for a long time . I ve finally tracked down how to replicate the issue but I do not know what is causing it or how to fix it . We have a number of cfc s in a web accessible controller directory that handle for submits and processing . When a cfc is called directly with no method argument the server begins to chew up memory . For instance an URL like http : www.domain.com controller LoginController.cfc will run in the browser until it times out . The CFIDE has been locked down and is not publically accessible .. . .. . so the cfexplorer is not or should not be available . We use FusionReactor to monitor our instances . Our servers are set for 20GB of heap space . On a fresh restart after loading the application memory will cruise around 800MB . With normal traffic memory will fluctuate between 5GB and 10GB with regular garbage-collection . After awhile the server eventually reaches 98 capacity . It tends to run there .. . .. . fine for hours or even days sometimes until some spike in traffic pushes it over and an outofmemory error occurs . Garbage collection recovers no memory and there are no active .. . .. . long running threads reported by FusionReactor . Only a server restart will recovery it . Using FusionReactor which we ve just installed which is how I finally got some insight into this issue I was inspecting the PermGen memory space and found that it accounted for .. . .. . 85 of the heap . This didn t seem right at all . I performed a memory-dump and loaded it into MAP through Eclipse to analyze it . I found that there were 10 objects in memory .. . .. . measuring 1.7GB 1.7x10 is approx 85 of total heap . These objects look like this : .. . .. . So I restarted CF on one of our servers .

Or was it fixed with a hotfix Is this only a CF9 issue Very confusing comment by Nimit Sharma . .. . Answer : I believe this is a legit bug in ColdFusion and I ve reported it through their bug system . The problem is partially repeatable on other systems . For instance on my MBP running CF on Apache a direct CFC call does not cause a memory issue but does results in an immediate JRun Internal Server Error page . So something wrong is going on and the systems are handling the problem differently . Anway.. . I ve found a workaround thanks to @iKnowKungFoo and lots of experimentation . Inserting a method key-value into the URL scope seems to solve the problem . The caveat is it has to be done in the onRequestStart method and not in the onCFCRequest method . From the docs is seems that a call to a CFC would go directly to the onCFCRequest but this does not seem to be the case . All requests go through the onRequestStart method first . When onRequestStart returns only then is onCFCRequest called AND only if the required method argument exists . So in this case onCFCRequest was never being called anyway because the method argument never existed . So here is the code that runs in onRequestStart immediately : .. . .. . This bit of code checks the extension on the requested page and if a method argument does not exist in the both the URL and FORM scopes it inserts a blank key-value pair into both for good measure . The check for the WSDL argument is there as I found that while this code worked perfectly suddenly the few webservices cfc calls we have broke . If the call to the cfc is WebService.cfc WSDL then the method argument is not required and CF handles the whole thing differently . So inserting the empty method value then causes onCFCRequest to be called properly on the completion of onRequsetStart . When the cfc is invoked with the invalid empty method name the onMissingMethod is now properly kicked off . That method promptly handles the bad page request and redirects to a custom error page . Since implementing this fix we ve seen memory usage go down on all servers from a consistent 98 to 15 . Memory graphs show expected sawtoothing of memory being used and collected . Overall performance has gone from an average page request time of 1200ms to 54ms without all these requests running rampant behind the scenes . Still I hope Adobe is able to identify and fix the problem .

Comment : Got it : bugbase.adobe.com index.cfm event bug id 3690526 https : bugbase.adobe.com index.cfm event bug id 3690526 thx", "Question : One of the more interesting features in Coldfusion is how it handles external requests . The basic gist of it is that when a query is made to an external source through cfquery or or any other external request like that it passes the external request on to a specific driver and at that point CF itself is unable to suspend it . Even if a timeout is specified on the query or in the cfsetting it is flatly ignored for all external requests . http : www.coldfusionmuse.com index.cfm 2009 6 9 killing.threads .. . .. . So with that in mind the issue we ve run into is that somehow the communication between our CF server and our mySQL server sometimes goes awry and leaves behind hung threads . They have the following characteristics . 1 . The hung thread shows up in CF and cannot be killed from FusionReactor . 2 . There is no hung thread visible in mySQL and no active running query just the usual sleeps . 3 . The database is responding to other calls and appears to be operating correctly . 4 .

Usually these hung threads appear randomly on otherwise working scripts such as posting a comment on a news article .

Answer : One of the things you should start to look at is the hardware between the two servers . It is possible that you have a router or bridge or NIC that is dropping occasional packets . This can result in the mySQL box thinking it has completed the task while the CF server sits there and waits for a complete response indefinitely creating a hung thread . 3com has some details on testing for packet-loss here : http : support.3com.com infodeli tools netmgt tncsunix product 091500 c11ploss.htm 22128", "Question : One of the more interesting features in Coldfusion is how it handles external requests .

Answer : We had a similar problem with a MS SQL server . There the root cause was a known issue in which for some reason the server thinks it s shutting down and the thread hangs even though the server is obviously not shutting down . We weren t able to eliminate the problem but were able to reduce it by turning off pooled DB connections and fiddling with the connection refresh rate .

Answer : so you could start out by using the operating-system monitoring tools to see if you have mainly reads or writes next step is looking at memory issues despite it being an disk IO issue maybe your servers are low on memory and thrashing the drives as they are swapping pages in and out-of-memory . if you have not done so turn on the template cache this will stop railo checking the file system on every page request provided you have the memory . if you have plenty of memory both for your OS and for the JVM and you have template caching on start looking for your busy pages in fusion reactor check for cffile cfdirectory and other tags in these pages... . good luck . also use of queries of queries is often a culprit in high disk-io as internally a database is used which runs pages to disk on large resultsets if I remeber correctly .", "Question : I ve a website written in CFML hosted on a Amazon ec2 istance with Apache and Railo.. .

You could always block those IP s from your firewall if they re causing you grief and costing you extra money . On a side note if Amazon is costing you so much money that it s worth your time to track down tiny little issues like this in order to reduce your costs then maybe it s time to look at a dedicated-server somewhere where you don t have to worry about getting charged for CPU time .

Is there a way to either do that or convert a group of XACML 3.0 policies into XACML 2.0 policies Thanks .. . Answer : Yes and yes . First of all can you generate XACML 2.0 policies programmatically Yes you can . The same applies to XACML 3.0 or any schema-based XML content . The way to do that in Java is to use JAXB . JAXB will take an XML Schema that you write and create a set of classes that correspond to that schema . The JAXB utilities will create the hierarchy of data-structures for manipulating that XML . quoting from What is JAXB and why would I use it http : stackoverflow.com questions 607141 what-is-jaxb-and-why-would-i-use-it .

Write XSLT to do it for you . XSLT is a language that will take in an XML schema or an instance of a schema and convert that schema to pretty much anything web pages PDF and of course XML too . XSLT is great for converting from XACML 2.0 to 3.0 . Have an XML tool do the heavy lifting for you .

What changes or issues will I run into in migrating my client app from making XACML 2.0 requests to making XACML 3.0 requests Comment : I get asked this all the time so I m posting it here as a FAQ on SO . .. . Answer : The biggest difference between Xacml 2.0 and Xacml 3.0 for your client app is that the structure of the attributes in the authz request have changed significantly in Xacml 3.0 . In Xacml 2.0 attributes were organized into subject resource environment or action categories using XML element tags : .. . .. . In Xacml 3.0 these categories are indicated using XML attributes instead of XML element tags : .. . .. . The Subject element in Xacml 2.0 becomes Attributes Category urn : oasis : names : tc : xacml : 1.0 : subject-category : access-subject in Xacml 3.0 for example . Ditto for the resource environment and action categories . This structural change simplifies the processing model for handling requests and makes it easy to extend the model with custom application-specific or domain-specific categories without running afoul of schema validation . There are new data types and functions defined in Xacml 3.0 for use in policy definitions . The AnyURI data type is now distinct from the string datatype . Several of the 2.0 combining algorithms have been deprecated in favor of new 3.0 equivalents that define more precisely how indeterminate states propagate up through the policy decision-tree . The old combining algorithms are still included as legacy artifacts . Xacml 2.0 requests and policies can be mechanically converted to Xacml 3.0 format with no loss of information . Converting a 3.0 response back to 2.0 format is doable if you stick to simple permit deny responses .", "Question : Has anyone been able to successfully generate C entity classes from XACML2 schema files I am getting Cannot use wildcards at the top level of a schema . I think this has something to do with xs : any elements . I have tried change the processContents skip from lax but to no avail . I get this using WSCF Blue http : wscfblue.codeplex.com as well as xsd.exe http : msdn.microsoft.com en-us library x6c1kb0s 28VS.71 29.aspx . .. . Answer : I have no problems running the Xacml3 schema through VS2010 XSD.exe but I do see this Cannot use wildcards at the top level of a schema error when trying to process the Xacml2 schema with XSD . XSD processes the Xacml2 Policy schema with no errors . XSD reports this wildcard error when processing the Xacml2 Context schema . The issue appears to be the combination of any and mixed true in the xacml-context : AttributeValueType schema definition . Other definitions of AttributeValueType in Xacml2 Policy schema and Xacml3 use an xs : complexContent wrapper around an ExpressionType extension which in turn contains xs : any and xs : anyAttribute definitions . The Xacml2 context : AttributeValueType does not contain this wrapper . Solution : Remove mixed true from the Xacml2 xacml-context : AttributeValueType definition and XSD will generate the correct class types for the schema . The generated AttributeValueType class will have properties for a list of elements and a list of attributes which covers all the bases .", "Question : I d like to declare some policies likes : .. . .. . how to write policy of this kind . I looked through the XACML3.0 core spec Multiple Profile they says .. . .. . I think this means that in the policy file i cann t use XPath in the AttributeValue to refer to multiple resources like i said in the first place right because the request is resolved to individual request each asking for a resource with a specified attribute id . Is there something in the specification i missed out or misunderstood or can anyone suggest a better way to do what i want Now i m wondering if using regular expression in the resource can do that . The corresponding function is urn : oasis : names : tc : xacml : 1.0 : function : string-regexp-match . P.S . : I m trying to setup a authorization server for my company XACML seems a good place to start with . But nobody around me knows about it . I would be appreciated if any one can give me any suggestion about setting up the access-control system . Comment : I d love to help out . What engine or solution are you using Oil answer your xpath question in a short while Comment : I try to base the authorization server on Balana an open-source from WSO2 . Comment : If they don t support regexp give the Axiomatics policy server a go Comment : They do the regexp is part of xacml core specification . Comment : Yes you are right but Balana doesn t cover 100 of the spec I believe . .. . Answer : I chatted with some of my colleagues at Axiomatics and the conclusion is that you do not need XPath but rather regular expressions . XACML provides a regular expression function that works on URI data types . It is called anyURIRegexpMatch and it takes in a string the regular expression and the XACML attribute to which to apply the regular expression . It returns either true or false .

Can you reference an external set of permissions in a policy The second question has been answered in the affirmative so I m revising the question a bit to focus on the how . Can someone provide a xacml policy snippet or even pseudo-xacml that requires a role attribute id will be provided by the request to be within a set of roles which are identified by another attribute id managed by external attribute store . For the sake of providing a starting point the following is an example from http : docs.oasis-open.org xacml 2.0 XACML-2.0-OS-ALL.zip . In this case the role is inline . Comment : It s really not helpful to rewrite a question into a different question after the first question is answered . Just create a new question so that the original question and its answers can stand as a reference for future generations . .. . Answer : Yes policies can be written to reference attributes that come from an external attribute store . However where the attributes actually come from is usually not specified in the policy itself other than perhaps by a naming pattern in the attribute ID . In the XACML PDP reference architecture it s the responsibility of the request context handler to resolve attribute IDs and produce values for the PDP . It goes something like this : While evaluating a request against a set of policies the PDP encounters an attributeID in a policy rule that it needs to form a decision about the request . The PDP asks the request context handler to get the value of that attributeID from whereever - the PDP doesn t care where it comes from . The request context handler may look for the attribute in the attributes provided with the request or in any number of external attribute providers such as LDAP or AD or SAML or plain old databases . The request handler might recognize naming patterns like namespace prefixes in the attributeID to know where to obtain it . You want your attributeIDs to be specific enough to know what they are and what they mean but not so specific that all of your policies break when you move your attribute provider to a different machine . Policies should be configuration independent . Ultimately where the request handler looks for attributes is a matter of configuration of the request handler PDP server and will vary by product vendor . Update : To answer the 2nd revision to this question .. . .. . You would write your policy to perform a comparison between the attribute value s provided in the request and a list of values provided by an external source . Keep in mind that an attribute designator returns a list of values since the request could contain multiple attribute values for the same attributeID . You can accommodate that by either by wrapping the attribute designator in a one-and-only reduction function or by using a many-to-many cross product match function that will test every member of list1 for a match in list2 . Unless you have a specific design requirement that the request is only allowed to contain one role attribute it s best to avoid the one-and-only reduction since it really limits your options . Your Xacml 2.0 policy could look something like this : forgive syntax errors my Xacml 2.0 is a little rusty .. . .. . The Xacml function at-least-one-member-of takes two lists as parameters . For every item in the first list it tests to see if that item exists in the second list . It returns true as soon as it finds at least one match . The attribute ...example : attribute : role from your example is the attribute you re expecting to be provided in the request . If you want to enforce that the attribute must be provided in the request you can set MustBePresent true in the attribute designator . The list-of-acceptable-roles.. . attribute is an attribute id that your PDP context handler recognizes and retrieves from some external provider . What prefix or pattern the context handler looks for and which provider it fetches from is a matter of PDP configuration . Ideally the naming pattern on the attribute id indicates a conceptual domain or namespace the id is associated with but the id does not explicitly indicate the physical location or provider of the attribute value s . For longer app lifetime with lower maintenance costs you want to be able to change your provider implementation details without having to rewrite all of your policies . You can have vendor-specific attribute ids that will probably only come from a single provider you can have application-specific attribute ids that could be supplied by multiple providers but only make sense for a particular application and you can have generic or standardized attribute ids that could come from multiple providers and be used in multiple applications . The Oasis standards body and domain-specific profiles are a good starting point for finding standardized attribute ids and their semantics or getting ideas on how to organize your own app specific ids . Depending on your PDP and context handler implementation it may also possible to use the Issuer field as a way to constrain the list of providers for an attribute . The Xacml spec doesn t say much about use of the Issuer field but the same goals of decoupling policy from provider implementation details still holds . Comment : Thank you for your response . Sounds like there just needs to be an attribute id for the set of the subject s roles . Comment : Yes that would do it for the policy def . You d then need a corresponding piece in the pdp request context handler that knows how to return the role names when the pdp says hey what s this attribute Comment : Updated to answer 2nd revision of this question . For future questions please create a new question instead of editing an existing question to preserve the context of the existing answers .", "Question : I went through the XACML document and it explains about maintaining authorization policies in an XML file the same can be done by keeping the policies in database My question is what is the advantage of storing policies in XML file like XACML over DB approach because at the end of the day its just parsing an XML or querying database . .. . Answer : @user3405607 : If I understand you correctly you are questioning the need for complicated XACML standard spec when a database evaluation engine would do the same job If so the answer is that a DB-based engine can only provide access-control decisions for simple rules mostly ACL related . For example if you have resources X Y Z and users A B C you could design a simple table like : .. . .. . But as you can see this will not scale . Of course you can then make role based ACL rather than using user - resource mapping . But again this will only cater to simple rules . How would you handle a simple rule A user in finance department can approve an order if he is not the one who raised the order and if the order amount is less than his maximum approval limit assuming the department is captured in an Active Directory Of course if all those details needed in the rule department order issuer amount max amount are all in a DB you could consider writing complex SQL queries to do the job for you but then again the policies containing rules can only get more complicated and soon you will end up with complex policies that turn into a complex decision-tree for which writing DB queries will be not worth the hassle . Also it will soon end up that you will actually have to write a good sized code to perform and parse all these queries and responses and in fact this will be the entity called a PDP in XACML literature . The need for XACML also goes beyond that since it defines a standards based policy language as well as a request-response protocol . I would suggest you to read up on some of the basic material on this matter since my explanation may not do justice to the complexity involved and the need for a dedicated evaluation engine that is not solely reliant on DB queries .", "Question : I wrote some obligations and advices but I was wondering if there is a widely accepted or formal way to do this properly In other words : Is there a standard or preferred way to use obligations and advices in ALFA I would really like to see an example how to define an obligation e.g . to log every request and its content in a layered policy that will always be triggered on every request both on deny and permit Or do you have to define a separate obligation for every Policyset policy and rule Do you have to define the exact content of such an obligation or is this depending on the functionality of the PEP .. . Answer : This is a great question . While the specification all versions do define the structure of an obligation and even advice in the case of XACML 3.0 the specification doesn t mention how the PEP policy enforcement point is to implement the obligation . All the specification mentions is what should happen if a PEP fails to implement an obligation i.e . what happens to the decision .

You have to define the obligation twice : once on permit and once on deny Comment : @Morei I now added an example . Comment : Thanks again @david-brossard . If I understand correctly you always have to define an obligation within an on permit or on deny statement that comes right after the permit or deny keyword . For a policy it would be very appropriate to have an obligation that will alway be triggered . For example by having a kinda else or other branche that comes with the on deny and on permit . But I guess that s because XACML doesn t support it either Comment : That s correct . XACML forces you to define when the obligation will trigger .", "Question : I want to answer questions like what am I allowed to access by using XACML is their a workaround other than Axiomatics ARQ .. . Answer : I guess you want to ask the question what are the resources that bob can access from XACML PDP rather than just hoping for aboolean type permit deny result . According to the XACML core spec There is no mention about this type of queries . But You can implement it . One way is to use multiple decision profile . PEP can send all resources in the system actions and user bob in to the PDP Then PDP would response with multiple XACML results and PEP can filter out the permitted resources .

Answer : This is a great question . We call this issue the attributes of relations challenge . Essentially a user has a role within a given context or scope as you call it . If I read a user s role from the db based on the user s identity only then I would get back the list of roles independently of the scope e.g . editor publisher reviewer.. . This would lead to the risk I could edit a post outside the scope for which I have the right role . There are several ways to solve this issue . One way is to define stricter mappings in your policy information point . Using Policy Information Points .. . .. . Assume that the XACML request says : Can Alice edit post 123 . Your policy would state in ALFA syntax : .. . .. . The notion of scope doesn t directly show up in the policy . The underlying mapping to the source of attributes would be as follows : .. . .. . map userRole to the field role of the table usersRoleAssignment using SELECT role FROM usersRoleAssignment WHERE uid AND scope .. . uid would be mapped to the user identity that came in the XACML request . scope would be a resource attribute that would also be mapped in the PIP as follows .. . map scope to the field scope of the table posts using SELECT scope FROM posts WHERE pid .. . pid would be mapped to the identifier of the post in question . That also came in the XACML request . This means that your attribute userRole should really be called scopedUserRole . The modeling I gave is just one example . There are several other ways you could model with the same effect . Either way all the heavy lifting happens inside the PIPs . The main drawback is that you lose visibility of the semantics of your authorization logic . Using attributes values and functions .. . .. . Another way of achieving a similar result is to store the relationship between scope and role in the value itself . This is what you allude to in your question . You can use string functions such as string-starts-with or string-ends-with or string-contains to achieve what you re interested in . There is also a string-regexp-match function you can use . Details on the functions can be found in the XACML 3.0 specification http : docs.oasis-open.org xacml 3.0 xacml-3.0-core-spec-os-en.html Toc325047236 . If the functions are not sufficient in XACML you can : .. . .. . implement your own .. . implement a PIP that can process your attribute values and produce new ones . More on PIPs here http : developers.axiomatics.com blog index entry policy-information-point-in-five-minutes.html . Creating a new datatype called tuple .. . .. . The problem with XACML is that it flattens relationships . Using a new data type with multiple parts i.e . a Tuple would solve the issue . That would require custom coding though and quite some work . Using the XML content inside a XACML request .. . .. . If all the information comse from the XACML request then it could be expressed as an XML payload as part of the Content element inside a XACML request . You could then use attribute selectors and XPath to retrieve what you are interested in . HTH .

Comment : thanks david . right now i prefer the second way in your answer . i use a uri-style string type to represent the relationship of the role and scope . it s good all i need to do is to apply a rule to the scheme authorization and path part of the uri and to define some function to get different part of the uri-style string . i think xacml should support more uri-related functions Comment : i m not quite agree with the pip way to do this . some reason as you said", "Question : I followed the link https : community.jboss.org wiki SAMLV2AndXACMLV2Integration . to run pdp using SAML envelope on XACML .

As you see that MustBePresent true in Subject Resource and Action of Policy-Target and Request contains none s Id .

I found PolicySet and Policy share many similarities like the combining algorithms etc . And to accommodate more levels PolicySet also can be self-containable . If so why not merge PolicySet and Policy into a single concept named Policy and make Policy contain other Policies and Rules .. . .. . Update : .. . .. . Speaking of Rule actually Rule doesn t differ with Policy much either except that Rule has Condition and Effect and doesn t have a combining algorithm . What I am thinking of now is merging the three conceptions : PolicySet Policy Rule into a single new Policy . This Policy is self-containable and can has its Condition and Effect . If its combining algorithm returns Intermediate then use its own Effect . The whole policy is not applicable if its own Condition fails to meet the request . I personally think this one-concept model is more concise and clear than the PolicySet Policy and Rule . .. . .. . For example for a four-level policy if there s a demand for a four-level policy for a big enterprise XACML will represent like : .. . .. . PolicySet - PolicySet s - Policy s - Rule s .. . .. . My modification would be : .. . .. . Policy - Policy s - Policy s - Policy s .. . .. . Compared to the XACML s two-level PolicySets and a level Policy and Rule I think a straightforward four-level Policies would be clearer .. . Answer : The fact both exist is a quirk of the language . You could imagine a language with a leaf element the rule and a branch the policy . Both Policy and PolicySet are very similar . When modeling in XACML you can assimilate them . You d have a policy that can contain other policies XOR rules but not both at the same time .. . .. . EDIT .. . .. . Following the OP s edit here is a bit more context . XACML Structural Elements .. . .. . XACML introduces 3 structural elements : .. . .. . PolicySet PS .. . Policy P .. . Rule R .. . .. . As the OP states PolicySet can contain Policy and PolicySet thus allowing for an overall tree that is as deep as the author wants it to be PS -- PS -- PS .. . -- P -- R . Contents of PolicySet Policy and Rule .. . .. . All three elements PS P R can contain : .. . .. . Target elements : the target is what defines the scope of the element . A target is made up of an AND OR AND structure and attribute matches e.g . role manager OR role editor . Obligations advice : obligations and advice are statements that are returned along with a decision from the PDP policy decision point back to the PEP policy enforcement point .. . .. . Combining Algorithms .. . .. . Because PolicySet and Policy elements can contain children they need a mechanism to resolve conflicts between children . That mechanism is called a combining algorithm . Therefore both PolicySet elements and Policy elements have a combining algorithm property . Since PolicySets contain other PolicySets and or Policy elements the combining algorithm in a PolicySet is called a policy combining algorithm . Since Policy elements contain Rules only the combining algorithm is called a rule combining algorithm . Another quirk of XACML is that the list of combining algorithms for policies is nearly almost the same as for rules . The notable differences are : .. . .. . only-one-applicable exists only for policies . on-permit-apply-second exists only for policies . Here is the list in the ALFA https : en.wikipedia.org wiki ALFA XACML notation ALFA is a pseudo-language developed by Axiomatics http : www.axiomatics.com solutions products authorization-for-applications developer-tools-and-apis 192-axiomatics-language-for-authorization-alfa.html to simplify XACML policy authoring : .. . .. . Targets Conditions .. . .. . Targets .. . .. . As previously stated Target elements can exist in any of PolicySet Policy and Rule . A Target has a set structure of AND OR AND elements to combine together attribute matches i.e . the comparison of a given attribute to a given value . XACML provides a long list of functions that can be used . In a target only functions that take 2 atomic-values and return a boolean can be used e.g . or urn : oasis : names : tc : xacml : 1.0 : function : string-equal . Other functions e.g . sum urn : oasis : names : tc : xacml : 1.0 : function : integer-add cannot be used . Conditions .. . .. . In particular there is one really useful thing Target elements cannot do : compare two attributes together i.e . establish a relationship . Imagine for instance you want to write a Policy that states : .. . .. . Doctors can view the medical record of a patient they are assigned to . Or in other words Permit if userId assignedDoctorId . This is where Condition elements kick in . A Condition is an expression that can use any function available in XACML . The overall outcome of the Condition must be a boolean but now you can do things like sum age limit 5 or userId assignedDoctorId . And here comes another quirk : Condition elements can only be used inside a Rule element . So if you want to express a relationship in XACML you will need to have at least one Rule . And since a Rule element cannot live on its own . You will have to have at least one Policy element . So the smallest possible XACML policy is using ALFA : .. . .. .

Answer : I too encountered this issue and the reason was due to some conflicts of copying org.wso2.carbon.identity.entitlement.stub jars in different versions when installing XACML via feature manager . If you are installing XACML 2.2 and XACML mediator 2.2 it should copy org.wso2.carbon.identity.entitlement.stub 4.2.1 . I could resolve it as follows .. . .. . 1 . Go to repository components and open artifacts.xml . Find the artifact id org.wso2.carbon.identity.entitlement.stub and change the version to 4.2.1 there may have two artifacts with different versions 4.2.0 and 4.2.1 .. . 2 . Go to repository components default configuration org.eclipse.equinox.simpleconfigurator and open bundles.info file . Find the line org.wso2.carbon.identity.entitlement.stub 4.2.0 and remove it . there should be a same entry with version 4.2.1 .. . .. . Then try to publish to PDP .. . .. . Thanks Nipuni" ] }

Answer : I have a strange problem and am not quite sure how to narrow the source of the bug not a web developer . A web page 1 which visualizes about 8 megs of data renders correctly on chrome and safari but blows up on firefox possibly IE as well . I m using dimplejs visualization library which is based on D3 . I wrapped the dimple library in my custom created tags created using x-tag webcomponents to remove chunks of imperative javascript . Firefox shows only one of the 35 charts and even that is extremely garbled . Further firefox console shows NS ERROR FAILURE : error in the dimple library but I can t find much information on that error seems to be a catch all error . I m not clear on the error being in firefox dimple my x-tag implementation or some combination of all three . Dimple is not too popular yet and x-tag is extremely obscure hard to find info on them . Forget about a solution how can I find out which component library is causing the problem 1 http : rule605.targetcompid.com report.htm mc ALL symbol ALL month 201409 http : rule605.targetcompid.com report.htm mc ALL symbol ALL month 201409 Comment : Just for info opening error console I receive 78 JS errors all related to incorrect path values for example containing NaN might be the same problem I think you have a problem while receiving the data . The NS ERROR FAILURE normaly indicates that you have a XMLHttpRequest onerror handler in which you tried to read the result s status or statusText when that value is not available on the object . Comment : @axel.michel I believe those errors are due to data d3 looking up values when they don t exist . Unexpected zeroes missing axis etc . In other words I believe those errors are just due to the nature of data .", "Question : Hi all I am trying to create a custom Polymer Element that uses the x-flipbox element inside its template tag . However it seems that the x-flipbox tag-it is only working on the index page and not inside my custom elements . This is my custom-element what am I doing wrong The element above is just showing the two divs . This one pasted in the index.html shows only one div as it should .

Answer : You don t need to include it as a import that s an old wrapper thing the Polymer folks wrote for including X-Tag elements it s probably what s complicating this . You can simply include the JS as a script and CSS as a link rel stylesheet inside of the x-flipbox repo s src directory where you have your link rel import for the flipbox .. . .. . Repo : https : github.com x-tag flipbox tree master src", "Question : What would be the way to document a web-component using jsdoc3 http : usejsdoc.org .. . .. . Here is an example of web-component registered with x-tag . .. . Answer : Since X-Tag is also just JavaScript you can simply use the corresponding annotations provided by jsdoc . So things like @memberof etc . However Web Components syntax can have its own kind of additional meaning . For example you probably want an annotation for @element or @lifecycleCallback and stuff like this . This is not provided by jsdoc and therefore e.g . Polymer uses it s own documentation annotation using core-component-page . You either use what jsdoc provides and see what annotations fit best for your use-case or you use something like dgeni https : github.com angular dgeni which lets you build a documentation tool pipe entirely from scratch so you have full control over your annotations etc . Comment : you can simply use the corresponding annotations provided by jsdoc : this is my question : is there a usual way to do it Should I use @lends creates types with @typedef etc .

I don t like the is so I m actually just creating an inner element in your case an inner b . Comment : Thanks for filing this . I m getting the sense that extends is not going to save you any time effort based on the latest comment on the bug : It probably isn t testing anything you need it to at the moment because while you can use an existing native element prototype as your base none of its methods will work on the newly created x-whatever element you make .", "Question : How can I select nodes that begin with a x- tag name here is an hierarchy DOM tree example : .. . .. . jQuery does not allow me to query x- is there any way that I could achieve this Comment : Is this valid at first place x-map x-map Comment : actually is a new way to declare custom elements just like x-tags.org http : www.x-tags.org or polymer-project.org http : www.polymer-project.org project Comment : @Scott Selby : : contains is for text not tag names .

Answer : It might not be efficient but consider it as a last option if you do not get any answer . Try adding a custom attribute to these tags . What i mean is when you add a tag for eg . x-tag add a custom attribute with it and assign it the same value as the tag so the html looks like x-tag CustAttr x-tag . Now to get tags starting with x- you can use the following jQuery code : .. . .. . .. . and you will get all the tags that start with x- Comment : I thought about this solution also. . but the problem is that you need to add an attribute everytime the idea behind the tag name beginning with x- was to help querying instead of allowing all type of custom elements without any pattern Comment : @mateusmaso : Off topic but I wonder such an idea was even proposed . We ve had a markup language that looks like HTML but provides namespacing out of the box for over a decade now it s called XML and it manifests in HTML as XHTML . Then again jQuery doesn t support XML namespaces anyway http : stackoverflow.com questions 11502641 how-can-i-handle-xml-namespaces-in-css-selectors-or-in-jquery 11502677 11502677 making that point quite moot .", "Question : I m working on my first X-Tag application and on it s page it says it s meant to work with Web Component API s such as Custom Elements Shadow DOM Templates and HTML Imports . I ve started working on my templates but what s the best option to import them now that HTML Imports have been deprecated Comment : what browser would you target Comment : Latest versions of Chrome and Firefox . .. . Answer : AFAIK HTML Imports https : www.w3.org TR html-imports have not been deprecated or is it new . It s only Mozilla who said it won t implement it for Firefox . But the polyfill http : webcomponents.org is still available and supported . Since ES6 Modules http : exploringjs.com es6 ch modules.html are not implemented yet I would say HTML Imports are still the best option it s the one I chose as they are very easy to use and work well Polymer uses them extensively . Instead you can try RequireJs http : www.requirejs.org or implement your own module loader with XMLHttpRequest . I don t recommend you to use a ES6 Module Loader polyfill as they are only at experimental stage . Comment : Mozilla are on record as saying they don t intend to ever implement HTML Imports a currently specced and Apple have said that if they ever implement anything for declarative HTML imports it won t be until after ES6 modules are deployed and we have some experience from that to draw on .

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 .

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 .

Please clarify me how can I ask at news : comp.mail.sendmail", "Question : I ve a requirement in which i need to send 10000+ mails on a quarterly basis . For this purpose i used a windows service that triggers every day and executes the mailing functionality only after the third month . I ve to fetch last three months records from database and need to send one mail for each record . The problem i faced was the mail-server i used do not allow bulk mailing . How can i do this effectively by providing a delay between each sent 20 mails per minute .. . Answer : There are many way to archieve this . We once had a similar requirement and solved it via a home grown service which would fetch items from a special database-table mail queue and sent each mail individially . The queue is filled over time by regular business logic . The necessary locking can also be done via db : a SCHEDULE column stores the expected scheduled time of sending the mail . That way the service collects only those mails wich are ready for sending . After successfull send another column SENT TIMESTAMP is used to mark the success . We implemented the whole service in ASP and triggered it via regular Windows Task Planner jobs . In your case the service would start every minute and the queue would provide the next 20 mails . An even easier way could be to utilize SQL Server Jobs . SQL Server is capable of delivering mails to a local SMTP server as well .

My website sends requests for data confirmation to users a few times each day while I do my daily data maintenance . I sent a test message to my Gmail address and found that if you read your mail through Gmail webmail interface it will sometimes tell you Why the message was spammed . Very useful . It gave the reason A lot of messages from hp19.hostpapa.com were spam . I am on a budget shared server and I assume a hundred other spammers have bought accounts on the same machine as mine and are using it for evil . My site is non-profit so buying a dedicated box to avoid spam is not an option . So.. . .. . .. . My solution was to change my CMS to not use PHP mail at all . Now my CMS simply displays the message and a mailto : link with Subject parameter set . Now my process is to hit CTRL+C Click the link CTRL+V and hit send . Messages are sent from my computer s IP Address not on any blacklist using my mail client Thunderbird . This takes me just a couple of seconds longer than it did when my CMS used PHP mail to send the message for me . However I have found I am receiving a lot more replies so I am happy that the vast majority of messages are not getting spam-binned . I appreciate this manual solution is not appropriate for automated bulk messaging but for small non-profit sites on shared server who trigger each message with a click I thought it was worth sharing .", "Question : I am a little desperate with a problem in our web server .

Thanks in advance for your help Comment : Please do not cross-post to multiple Stack Exchange sites . Instead select the single most appropriate site and post there . .. . Answer : How does sendmail works for sending mail .. . .. . It is not a short story . Anyway to reduce number of sendmail processes you may configure your php to send via smtp protocol to port 25 on 127.0.0.1 loopback interface . It will create only owned by root sendmail processes . You should also define confDELAY LA confQUEUE LA delay .. . .. . confDELAY LA slows speed of accepting new mails when system load average is higher than configured limit . It may will make your script run longer . confQUEUE LA skips at once delivery attempts - you most likely should increase number of queue runners processes . In short : you push your sendmail server beyond limits standard simple configuration is assumed to handle with ease . Comment : In our sendmail.mc : FEATURE conncontrol nodelay terminate dnl FEATURE ratecontrol nodelay terminate dnl Comment : what changes would you suggest for our scenario Thanks Comment : conncontrol ratecontrol - it is not important if you have entries in access table etc mail access turning it off for loopback addresses . e.g . clientrate : 127 0 and clientcon : 127 0 . Comment : I would suggest 1 swithing php to smtp 127.0.0.1 : 25 2 Increasing after some test confQUEUE LA in sendail configuration - I think many modern servers can handle higher loads especially Linux which computes LA in another way giving higher values 3 IF mailq would report many messages in queue THEN increase number of queue directories - sendmail.org gshapiro 8.10.Training mqueue.html http : www.sendmail.org gshapiro 8.10.Training mqueue.html - use var spool mqueue with extra directories named var spool mqueue1 var spool mqueue2 ... .

Is there any way to skip the error and continue with next email id . I am using email id s from database . .. . Answer : In PHP you can suppress error display by adding @ to the function . This will usually prevent the error from being displayed . For your situation you can put the code in try..catch . In the catch section check if the all the emails have been sent if not just continue with the next one . This also means that you need a way to track the total emails and the number of emails completed . Hope this helps .", "Question : I have setup a network monitoring system at my office that monitors activity over my network and shoots me an email at certain triggers that i have setup . I have put together an application that quickly does the job for me custom made for the kind of monitoring that i need and rules that i have setup . Now everything is fine and i have setup the emails to be sent using gmail smtp using swift mail plugin . The problem is gmail is locking my gmail account if a burst of emails is sent or atleast that is what i think . What happens is sometimes theres a lot of activity and the system sends like 50 or 60 emails over a short span of time like in a minute or two . Immediately gmail blocks access to the account and when i open the account in my browser it asks to verify my account . Even after unblocking it the server is still not able to open to gmail account using smtp or imap . This is getting annoying and i would like to know if there is a way to stop gmail from blocking access to an account if it knows that the access is from a specific IP or if there is a better way to send lots of emails . Comment : 1 Could you name OS distribution you use windows linux It may help to find eliminate available tools 2 Does your office use fixed IP permanent internet-connection I assume yes but I prefer to be 100 sure .. . Answer : You can t send the bulk emails from Gmail Account . On an average bases GMail allows 300-500 Emails daily according to the email usage and sent and received emails . For sending bulk or more email either you have to use the Paid service such as MailChimp etc . or send the Emails through your own Server . But if you are using the Shared Hosting server then also the Service Provider controls the Sending of Emails daily . Generally about 2500 - 3000 daily Emails are allowed and if it also crosses the rate of sending emails of 100 125 Emails hourly then they will also dis-allow you account or de-activate your account after giving the warning . The main reason for the precautions are to stop the sending of the spam through automatic process . If the Emails are note spam and numbers are high then it is always recommended to your paid service which provide the API access for sending the Emails .", "Question : I have a domain with http : www.myacademicproject.com for Final Year IT Students Internship students to whom I am sending the mail .

Answer : Host your audio file on a website then provide a link-to that audio file in your emails . That way all your emails are light-weight and are not clogging people s inboxes . Comment : If you re hosting the file you can control who has access to it and for how long . You can also set up an authentication system on your own site that forces users to verify their email-address and maybe an auth token to listen to the recording .

Answer : We are using Rails 2.3.8 version . In our application we tend to send individual email to all users around 1500 users - Bulk email . We are not using any services other than Actionmailer . Hence we cannot use any service like mailGun sendGrid mailchimp etc Also we have our own SMTP server through which all the mails are sent . We have added our mailing functionality to be executed in two scenarios . 1 . Rake Task with CRON JOB Auto mails to be sent at specific time .. . .. . 2 . Via controller Mails are sent when a button is clicked .. . .. . In both the cases Initially the mails are forwarded to the users without any issues . As the user count increases suddenly the mail functionality stops and throws either of the two following errors . 1 . 535 5.7.3 Authentication Unsuccessful .. . 2 . Execution expired .. . .. . Could anyone please help me sort out the issue Is there any timeout value that has to be set for SMTP server connectivity Or are there any restrictions like number of mails sent per minute Thanks in Advance Comment : It sounds like these issues are caused by your SMTP server . Usually there are restrictions on mails that can be sent and if you are sending them from a gmail address for example then google might also step in if you send too many flagging them as spam i have received 24 hour bans from google before for testing mass emailing through my gmail account . Usually you would configure actionmailer to send eg 200 every minute or something . Comment : Thanks Max for your reply . But 1500 mails does not seem to be too many . Because large amount of mails around 10000 or more could be sent from Rails applications . Sending 1500 mails from our application takes a very long time nearly 1 hour for 350 mails . Comment : It doesn t matter how many emails someone else is sending from their rails application and whether you think it isn t too many . What matters is your SMTP server config . For all you know it may be set up with a limit which is not adequate for your needs . I suggest you investigate this rather than dismiss it as not being possible . Comment : Not a direct answer but you should seriously consider mandrillapp.com . Makes life so much simpler and you may fit into their free plan with that volume .", "Question : We send a lot of emails to a lot of our users ranges in 20k+ per day . One of the major problems we face are invalid or dead emails - sometimes our users delete their accounts change their email-address without updating their profile or our email database builders simply caught emails that are invalid or no longer active . These unresolved returned status messages keep not only piling up on our webmaster account but also waste precious server resources and flag us as spam more often because of the repeated attempts . Now while our mail-server is set up to keep trying to send an email to an address that returns temporarily unavailable I would like to be able to receive status messages into PHP immediately after sending . For example when my Sender class sends an email I would like to know the status message that was returned - whether the email is no longer active or the server does not exist or the email was simply moved to another address . Naturally I want to be able to receive a status message of a delayed email as well . So if an email does not get sent because the recipient email-address is temporarily unavailable I would like to get the temporarily unavailable message back into Php but I would also like the real one to get passed back once the sending succeeds for example if the email does go through 2 days later . Is there a library that would help me achieve this What are the most common approaches to this problem if any .. . Answer : Like most questions about PHP and mail this is mainly about the MTA . Bulk emailing is a science in its own right OK so more like a black art and at these kinds of volumes you need to up your game a lot if you want reasonable rates of deliverability . But back to the question . An awful lot of this is about how you configure your mail-server . AFAIK most MTAs will only send back a failure message when the message is removed from the queue e.g . after the last attempt at delivery . Which gives 2 options for tracking each attempt : .. . .. . 1 parse the log files .. . .. . 2 set the number of attempts to 1 and optionally handle re-queueing yourself . Given that a message can fail to be delivered after it has successfully departed from your server it makes a lot of sense to use delivery status notifications i.e . bounce emails to track the progress of messages - so using option 2 avoids having to build different code for handling different scenarios . Without knowing what OS this is running on nor which MTA it s impossible to give more specific recommendations . Comment : We are flexible on the MTAs and would not mind replacing it if one would perform better for our needs . The OS is Linux . Right now we use sendmail in some cases and Zend Mail Transport Smtp in others . Comment : I have created a library for sending for my company . We can process parse and create 1000 different emails to 1000 different recipients from 1000 different senders in under 2 seconds while the actual sending the - send command takes 30 seconds for the whole 1000 . This is acceptable for us . Now we use a direct Zend transport for latching onto the server and sending that way . In a way we don t use a real MTA . As previously mentioned the server is Linux based . As for your suggestions - do you perhaps have an example of solution 2", "Question : I am trying to send bulk-email from gmail using php in which from address to address and message are set from a form .

I have already developed an application that sends bulk mails nearly 1 million hour using SMTP client . But when it reaches particular limit I m getting Operation timed out error message . When I checked in my SMTP Server Dedicated Server I ve seen that there are a lot of mails in queue and the ratio of mails sent to remote servers is very low compared to the mails coming from the SMTP Client .

Also please provide me the links of source code samples . Then I can easily refer and create a good one . Thanks in advance . Comment : This seems like the wrong way to solve the problem . There are plenty of SMTP servers available already . It s highly unlikely that you re going to build a better one than any of the available ones .

Please help me to develop an SMTP application . I have searched a lot for getting some source code samples . But unable to find out . Comment : If your email volume is beyond the capability of your local hardware perhaps it s time to utilize an off-site email distribution service . There are many of those to choose from as well . The point is writing your own SMTP server just because yours doesn t meet your needs is like writing your own OS just because Windows crashed once or building your own car just because the check engine light came on once . I don t doubt that you re having issues with your current setup but the solution you propose is absolutely not how you go about fixing it . .. . Answer : Sounds to me like you are adding mail to the queue faster than the smtp server can send them so the queue gets longer and eventually takes too much time to send an individual email so it times out . You can change the timeout of an email from the default 100000 ms in C to whatever you want to keep it from timing out . This will not solve your problem but if your problem is a peak valley problem it may smooth it out . With this strategy you are playing with fire your failures will be delayed more with the potential of losing more with each failure . I suggest adjusting your hardware maybe a second smtp to relay off of or something of that nature . I just hope i m not enabling a spam bot with this post . Comment : OK. . I ll try to increase time out to 1 Hour . I have found an alternative option . Actually I m using Mail Enable SMTP Server . I got an option to inject mails directly to SMTP Outgoing Queue folder .

Edit : I found HOW TO use Quartz.NET in PRO way http : blog.goyello.com 2009 09 21 how-to-use-quartz-net-in-pro-way to be really useful . .. . Answer : A few weeks ago I wrote about using Quartz.Net to schedule jobs in Windows Azure Worker Roles . Since then I ran into a requirement that pushed me to create a wrapper around the Quartz.Net IScheduler . The JobSchedule has the responsibility of reading a schedule string from the CloudConfigurationManager and schedule a job . The CloudConfigurationManager reads settings from the Role s configuration file which can be edited through the Windows Azure Management Portal under the configure section of your cloud services . The following example will schedule a job which needs to be executed everyday at 6 AM 8 AM 10 AM 12 : 30 PM and at 4 : 30 PM . The schedule is defined in the Role settings which can be edited through Visual Studio . To reach the Role settings go to your Windows Azure Cloud Service project and find the desired Role configurations under the Role folder . Open the configuration editor by double clicking on the configuration file then navigate to the Settings tab . Click on Add Setting and name the new setting JobDailySchedule and set its value to 6 : 0 8 : 0 10 : 0 12 : 30 16 : 30 .. . .. . Then using the JobSchedule schedule a daily job using the schedule defined in the Role s configuration file . The DailyJob implementation goes as follows . Since this is a demo I will not add any specific logic to the job . The JobSchedule wraps the Quartz.Net IScheduler . In a previous post I spoke about the importance of wrapping your 3rd party tools this is an excellent example because I am containing the job-scheduling logic and I could potentially change this logic without affecting the code that is using the JobSchedule . The JobSchedule should be configured when the Role starts and the JobSchedule instance should be maintained throughout the Role s lifetime . Changing the schedule can be achieved by changing the JobDailySchedule setting through the Windows Azure Management Portal under the configure section of your cloud services . Then to apply the new schedule restart the Role instance through the Windows Azure Management Portal under the instances section of your cloud services .", "Question : Im doing a proof of concept with Quartz.Net A fairly simple scheduling task the only requirement i have is that a restart of the service it not needed to reconfigure quartz .. . .. .

Thank you .", "Question : I m creating a scheduler using Quartz.NET in the current project . In my case all the jobs that has to be created are stored in a single table and there is a separate UI where I can add new jobs or edit existing jobs . My question is how I can feed all the jobs in the table to the Quartz scheduler Do I want to query for all the jobs in the table and iterate through it creating the JobDetails and Trigger objects Is there any better way in this case In this case do I want to use a RAMJobStore or AdoJobStore .. . Answer : you can use AdoJobStore . Quartz.net will use a set of tables with prefix QRTZ you can change it if you want in your database to stored jobs triggers and status of these objects . I guess you want to have a table in your DB where you re going to keep extended information about your schedules right You won t access Quartz.net table directly cause you will use the APIs provided by Quartz.net . The process to create a job detail and trigger is straightforward and described very well in the tutorials http : quartznet.sourceforge.net tutorial index.html . To configure your app to use the AdoJobStore http : quartznet.sourceforge.net tutorial lesson 9.html you have to specify few informations in your app.config file . Here is an example : .. . .. . There are few things to keep in mind depending if you re hosting Quartz.net in a web application or a service or winform app . The best approach is to create SchedulerFactory and Scheduler as singleton . You can gather some more infos here http : jvilalta.blogspot.com search label quartz.net 201.0 . UPDATE : .. . .. . First of all you have to create Quartz.net tables see Step 1 http : jvilalta.blogspot.com 2010 04 configuring-quartznet-with-adonet-job.html and then you ll have to create a few indexes for optiomization see bottom of the page http : quartznet.sourceforge.net faq.html howtoimproveadojobstoreperf . Since you re going to submit your jobs using the web app but you re not using that app for the quartz.net events triggers you don t need to start the scheduler . There are few steps to follow on this side : .. . .. . you have to change the thread pool type to ZeroSizeThreadPool .. . .. . and you have to define your StdSchedulerFactory and Scheduler singleton . You can start during the application asp.net bootstrap . You re never going to start the Scheduler your windows service is going to use that . Another thing to remember is you re going to need share your job http : quartznet.sourceforge.net tutorial lesson 2.html between your web and your windows service so it would be better to keep it in a separate assembly . You mentioned you re storing some infos in one of your table . You still need to have to submit your jobs and trigger which will be persisted in Quartz.net tables . Comment : Thanks for your reply . I ve a single table in database that stores all the jobs information for the business . The scheduler is running in Windows service and through an ASP.NET application jobs are added to this table or edited . So how I can use Quartz.NET in this case Whenever a job is added or edited the scheduler has to be updated . Comment : @Dnana : is that your windows service or Quartz.net windows service Comment : .net windows service . i m not sure which one is better in this case .

Answer : I want to put together a scheduler for web data-processing to limit the number of jobs so I used the Quartz.Net framework and put that on top of IHttpAsyncHandler .

This in turn causes Quartz to set the trigger for the job to an error state . When this occurs the trigger will cease firing until some manual intervention occurs restarting the service since I m using in-memory job-scheduling . How can I prevent the error state from being set or at the very least tell Quartz to retry triggers that are in the error state The reason for the exception is due to flaky network calls that are required to get configuration data that is passed in to the job s constructor . I m using a custom IJobFactory to do this . I ve seen other references to this without resolutions : .. . .. . https : groups.google.com forum topic quartznet 8qaT70jfJPw .. . .. . http : forums.terracotta.org forums posts list 2881.page .. . Answer : Simply put you should follow good object oriented practices : constructors should not throw exceptions . Try to move pulling of configuration data to job s execution phase Execute method where retries will be handled correctly . This might mean providing a service func via constructor that allows pulling the data . Comment : I m using a IoC container to construct the job along with its constructors arguments . As such I m not throwing exceptions in my constructors . I d consider this an oversight of Quartz.net . It is possible that my job may not be able to be built some of the time and it should be treated as a transient error not a fatal one . I could return a null object but that would just push the errors further down .

Answer : A fairly robust implementation with ADOJobStore is to have a custom table to store jobs and create a class that inherits from ISchedulerPlugin and IJob to create schedules for your job automatically . Your config will look like this : .. . .. . Your plugin job class can look like this : .. . .. . Now JobSchedulerPlugin has entered a trigger into QRTZ TRIGGERS that will fire every five minutes with highest priority . You can use it to load jobs from your custom table let s call it QUARTZJOBS . QUARTZJOBS can contain information such as jobnames assembly paths dates status etc anything that can be used to help you create triggers efficiently . It should also contain the cron expression to the job . This is what you can do when the trigger fires : .. . .. . In each of the classes above you can add custom validation for making sure triggers are handled appropriately if status or cron expression changes . With this solution the server will never need to be restarted . The plugin job class will scan the table and act accordingly . Comment : ...load jobs from your custom table .. . jobnames assembly paths dates status etc.. . New to Quartz.NET it s my understanding that assemblies have to be in the same folder as the Quartz.NET runtime . But I m intrigued by your claim otherwise and would like to implement--could you elaborate Tx . Comment : I m not finding classes JobCollection or JobsWithTriggers in the Quartz.NET source--can you assist Tx . Comment : @InteXX As you ve seen assemblies don t necessarily need to be in the same folder as long as you have a reference in the project . Quartz.NET loads them via reflection . Personally I put the assembly path in the QUARTZJOBS table and load it to the scheduler in the ScheduleJobs method . I have separate projects for my jobs in order to group them better which is great for architecture . Comment : @InteXX JobCollection and JobsWithTriggers are not in the Quartz.NET source they are custom implementations . JobCollection are entries in the QUARTZJOBS table which LoadJobs method retrieves from database . CreateTriggers does some basic validation . For example I have an IsActive column . If it is set to false the CreateTriggers method will delete any job triggers via the API . If it is active and there is no trigger or a different trigger is specified it will add it to the table . Comment : @InteXX You can delete jobs on the fly with the IsActive column on the QuartzJobs table see answer above . Also do the same for assemblies . The next time the plugin fires it will take care of it . Documentation like you say is lacking for the more advanced features this is generally a problem for open source- if you can expand it please do : Hope you ve found this helpful if so please upvote If you have any other questions feel free to ask ." ] }

Given that these effectively mean the same thing : .. . .. . Is there a historical reason why these 2 classes evolved Is one any better to use than the other in any particular circumstance This stems from the fact the I m using a javascript library embedded within a PyQt application I m currently using QWebView but only QWebPage has a method for catching javascript errors http : pyqt.sourceforge.net Docs PyQt4 qwebpage.html javaScriptConsoleMessage so was considering whether it was worth translating my code to subclass QwebPage instead .. . Answer : From the documentation http : qt-project.org doc qt-4.8 qwebpage.html it says .. . .. . QWebPage holds a main frame responsible for web content settings the history of navigated links and actions . This class can be used together with QWebFrame to provide functionality like QWebView in a widget-less environment . Also QWebView inherits from QWidget while QWebPage does not . My guess is therefore that QWebView is just a widget being able to load and display HTML while QWebPage can be used with a view or without a view . Also QWebPage has more functionality like settings or history of nagivation . Now a widget-less environment is for example QtCore.QCoreApplication . It seems that you would use QWebPage for example when writting an application for scraping web content while you would prefer QWebView when you just want to load and display some web content somewhere in your application . QWebView being a widget will always want to display something . Historically they were both introduced with Qt 4.4 . The open questions are how much they share internally and if there is something you cannot do or cannot emulate with QWebView that you can do with QWebPage", "Question : Apologies if this question is grounded in misconception . I m new to both webkit and Qt . I m trying to get a feel for what circumstances would justify using a QGraphicsWebView instead of a simple QWebView object . I understand one is more complicated to implement than the other . What added fliexibility does use of the QGraphicsView class add And why does Qt-Creator s default HTML5 application template use a QGraphicsWebView instead of a QWebView For example if I wanted to implement mouse gesture-driven scrolling and zooming or implement a custom-scrolling implementation would I need a QGraphicsWebView or would a simple QWebView suffice Comment : QWebView is based on the QWidget system thus it cannot easily support rotation overlays hardware accelerated compositing and tiling http : trac.webkit.org wiki QtWebKitTiling . .. . Answer : From Qt docs : .. . .. . The QGraphicsWebView class allows Web content to be added to a GraphicsView .. . .. . So QGraphicsWebView can be used as QGraphicsItem in the QGraphicsScene . Comment : I got that far . But what are the advantages of doing it that way Comment : No other advantages . The only difference between QGraphicsWebView and QWebView is their parent Widget .

Answer : Since I can t comment directly on your post for low reputation reason I am answering here . This question is very related : QWebView or QWebEngineView http : stackoverflow.com questions 29055475 qwebview-or-qwebengineview . Basically QWebView uses WebKit as the backend whereas QWebEngineView uses Chromium as the backend . These two links may interest you both referring to the latest version of Qt 5.6 : .. . .. . QWebView : http : doc.qt.io qt-5 qml-qtwebview-webview.html details .. . .. . QWebEngineView : http : doc.qt.io qt-5 qml-qtwebengine-webengineview.html details .. . .. . I am currently working with QWebEngineView and everything works pretty fine I haven t tested QWebView though . Comment : Yes that was pretty much all what I could find so far . However I need more detailed information than 2-3 sentences under details subtitle . Do you know where I can read more into it Comment : Keep in mind that Blink is part of Chromium . I think you should search for the difference between WebKit and Chromium and see what s best for you . And last thing you can do is looking at Qt sources in order to see how both are managed by Qt Comment : What do you mean by Qt sources Comment : The code source of Qt : wiki.qt.io Get the Source https : wiki.qt.io Get the Source Comment : Do I have to make webkit while making Qt from source in order to use Qt WebEngine Or can I say -no-make webkit", "Question : With Qt 5.5 using the Minibrowser example http : doc.qt.io qt-5 qtwebview-minibrowser-example.html they provide it uses something different than QWebView widget http : doc.qt.io qt-5 qwebview.html . Instead it uses QML and a QtWebView module http : doc.qt.io qt-5 qtwebview-index.html . When you look in Javascript s navigator.appVersion it lets you know that QWebView loads a custom AppleWebKit 538.1 a thing shipped with Qt5.5 while QtWebView note the difference loads the native core OS AppleWebKit 601.1.56 . This is confirmed because when I load Safari on my OSX El Capitan version it says 601.1.56 . The problem however is how can my Javascript functions in Minibrowser call C++ functions on the backend to do more powerful stuff When I was using the QWebView widget I was able to use the C++ webkit bridge http : doc.qt.io qt-5 qtwebkit-bridge.html that let me inject into the DOM my C++ object and therefore could call my C++ code . I m not seeing any technique documented for how to do this with the QML-based Minibrowser example that uses QtWebView . What s the technique EDIT : Oh and to clarify I m not calling remote web pages with this via a web server . I m just calling stuff through file : . In other words I m using the rich webkit interface to give me a super powerful GUI that goes way beyond what the Qt widgets and QML can provide for me . .. . Answer : I found the answer . Basically in Qt5.5 I m diving into experimental land with QtWebView . The class methods are largely undocumented and may change in the future . For now the only technique is message-passing not native C++ class-method invocation like you could use in the QWebView C++ Bridge http : doc.qt.io qt-5 qtwebkit-bridge.html . The QWebView C++ Bridge only works with QWebView widgets not the QtWebView QML . So you do this message-passing with navigator.qt.postMessage API from your Javascript to your QML and then QML can call C++ . In order to get that extra functionality you ll need to do a few steps . Here s an example : .. . .. . Invoke C++ method from webviews Javascript http : stackoverflow.com questions 14342220 invoke-c-method-from-webviews-javascript .. . .. . This is blogged a little here : .. . .. . http : rschroll.github.io beru 2013 08 21 qtwebview.experimental.html .. . .. . As you can see from the example you have to add these imports to your main.qml : .. . .. . Then in your WebView section you have to add this line : .. . .. . At that point you can call navigator.qt.postMessage call foo in C++ to send a message to the QML which you can then pick up inside your WebView section with : .. . .. . Your QML can then pass a message right back to the Javascript with : .. . .. . And then in your Javascript you can add an event-listener like so : .. . .. . As for how to get your QML to call C++ here s an example : .. . .. . http : stackoverflow.com a 17881019 105539 .. . .. . EDIT : After more experimentation in Qt 5.5 with QtWebView it appears fairly flaky in the following respects . I don t recommend it in 5.5 -- it s not ready for primetime . In Qt 5.5 you re better off using the QWebView widget for now and then migrate to QtWebEngine http : doc-snapshots.qt.io qt5-dev qtwebengine-overview.html when the next version of Qt comes out Qt 5.6 5.7 . By default it gives you a rightclick context menu you may not want . Interestingly you can turn it off if you import the experimental library and then set this property in your QML : experimental.preferences.navigatorQtObjectEnabled : true . By default HTML5 postMessage API the one native with HTML5 doesn t appear to work unless you enable experimental.preferences.navigatorQtObjectEnabled : true . When you enable experimental.preferences.navigatorQtObjectEnabled : true the scrollbars disappear if you enabled them on some HTML page elements the checkboxes and radio buttons look extremely funky and popdown select listboxes stopped working . When you doubleclick a page it zooms it . Comment : @MrEricSir I think you might be confused . I was referring to QtWebView being poorly documented not QWebView . QtWebView ships with 5.5 and only utilizes native webkit APIs which only ship on Android iOS and OSX but not Windows or Linux . QWebView on the other hand ships with 5.5 but comes with an older but still usable version of webkit . Comment : @MrEricSir Also it appears that QtWebView in 5.5 just isn t usable yet -- stuff breaks as I explain above . So one really has no choice but to use QWebView for now which will only work in 5.5 but will not ship past 5.5 and then migrate to QtWebEngine later . The bad news about QtWebEngine however is that it deploys with Chromium instead of Webkit -- a fat install -- and will likely not get you approved in the Apple Store .", "Question : Today I came across a very strange error with QWebView which I cannot resolve myself .

This means that when I am extracting or iterating over single values from a numpy datetime64 array I convert them into a datetime object first before I let propagate into other parts of the codebase .

How can I fix this I d basically like to write a simple wrapper for datetime64 which allows me to add custom functions such as obtaining the month of a given date with a simple .Month method . With the upper example I can easily add methods in the lower example it will never recognize my methods and thinks it s a datetime64 object . Comment : As a side note it s a bit misleading to call new s first argument self instead of cls . Also why aren t you using super Comment : Anyway for the general question types are supposed to usually return an instance of cls or a subclass thereof when you call new cls but there s no rule that they must and nothing you can do about it if they don t . For the numpy-specific question there probably is an answer but I don t know it off the top of my head so hopefully someone else does . : Comment : One quick thing I tried is to change the class attribute but NumPy declares its base types as non-heap types so that won t work Comment : One last thing : Why are you trying to do this If you store these things in an ndarray your dtype is either going to be datetime64 object or a custom dtype that stores the values as datetime64 and treats them as such in C API functions but auto-converts them when you box them up for Python . Unless you want object it really doesn t matter whether the type inherits datetime64 . Comment : Thanks for trying . I want to subclass because I want to keep the original behaviour of datetime64 but add some custom functions . Just like one can subclass to ndarray and there are many examples for that I m looking to subclass the very similar datetime64 class . .. .

Answer : datetime64 ns is a general dtype while M8 ns is a specific dtype . General dtypes map to specific dtypes but may be different from one installation of NumPy to the next . On a machine whose byte order is little endian there is no difference between np.dtype datetime64 ns and np.dtype M8 ns : .. . .. . However on a big endian machine np.dtype datetime64 ns would equal np.dtype M8 ns . So datetime64 ns maps to either M8 ns or M8 ns depending on the endian-ness of the machine . There are many other similar examples general dtypes mapping to specific dtypes : int64 maps to i8 or i8 and int maps to either int32 or int64 depending on the bit architecture of the OS and how NumPy was compiled . .. . .. .

I want to see datetimes in all timezones by the same way . .. . Answer : Mentioned a few times in the numpy documentation http : docs.scipy.org doc numpy reference arrays.datetime.html : .. . .. . The datetime object represents a single moment in time . .. . .. . .. . .. . Datetimes are always stored based on POSIX time .. . So internally a datetime64 is tracking a single integer which represents a moment in time as a value since the UNIX epoch 1970-01-01 - not counting leap seaconds . Therefore time zones are not preserved . If you pass in a time zone offset it will apply it to determine the correct UTC time . If you don t pass one it will use the local machine s time zone . Regardless of input on output it uses the local machine s time zone to project the UTC time to a local time with offset . Comment : POSIX timestamp is not unique around leap seconds . Comment : @J.F.Sebastian - Technically yes - that is correct . But many applications do not require such fine precision that leap seconds matter all that much . Still I will update my wording . Thanks . Comment : It is not about precision . It is about whether your program can handle possibly non-monotonous non-continuous timestamps btw you should handle such cases even if there were no leap seconds -- time.time may be set back that is why time.monotonic exists for relative times . POSIX time doesn t count elapsed seconds since the Epoch 1970 though an application may consider it so i.e . an implementation can synchronize UTC and POSIX time in some unspecified manner .

We have contacted our hosts media temple and they cant give me any resolution and we really need some help . Here is a video of my issue we are experiencing . http : bit.ly 1CEIYOH .. . .. . Here is a trace route to our api it works fine for many of our users but some are now getting issues like below . Network just drops out here is Media Temples response . We have received feedback from our provider s network engineer and he asked if your clients or the customers of softlayer open a ticket with softlayer . From what testing they have done it appears that there are some routing peering issues between various ISPs and softlayer . New update .. . .. . From your traceroutes the commonality appears to be either Softlayer Internap or NetDC ISPs . I ve spoken with NetDC and they claim they are not filtering anything . We have also reached out to softlayer but have not heard back from them . What would help narrow this down if we can run another script like you did earlier : .. . .. . Another update .. . .. . Ok I ve reached out to Softlayer your customer s ISP Internap Intermediary ISP and NetDC Intermediary ISP . One of them is filtering things and I m hoping I get a quick response from them . It is out of our control at this moment but hopefully these ISPs will be responsive and allow us to track down whatever is blocking your customers from reaching you . Latest update .. . .. . .. . Good news I got a response from Softlayer just as I sent you that last correspondence . They are seeing the same issue from their end .. . .. . .. . and they believe the issue is within Internap . They have looped in Internap as well since they are direct customers of Internap so hopefully something will be discovered . .. . I was able to determine that there are some ip subnets of ours that are accessible by the Softlayer router that was having issues connecting to your IP . I need to verify that we can actually migrate you to one of those IPs . .. . I m having an internet routing change made so Internap will hopefully not have the preferred route to your server and thus be bypassed I believe the issue is not limited to just your IP which is why I m taking this more extreme step . Can someone please help .. . .. . FINAL UPDATE . The final solution was to completely move away from Media Temple they have REALLY let us down with their hosting after 3 weeks of our customers having issues they could not provide a solution and when asking them this clear question . how come i can post to any other server but media temple from the ip thats having the issue Even the people on support where just literally just transferring me to another support operative because they could not answer the question . What worries me is how come a hosting provider cant fix something like this i lost quite a few paying customers due to this issue . Solution was to move everything over to Amazon and install it onto a EC2 instance which i managed to do in a day which i wish i had done from the start i also install a ssl cert for 3 whereas the one on Media Temple are 75 i also paid 100 for their Cloudtech service as well . Great thing about Amazon is even if a error like this did happen again i can just create a AMI and then just fire up a new EC2 and job done . Everyone be careful about issues like this with third party hosting if you service relies on a API and you are given ISP issue then your business can go under very quickly if your hosting cannot find you a solution after 3 weeks of try belief me your users don t want to hear oh i am just awaiting a response from Media Temple .

Answer : What help are you expecting from the community I am Sure that is just the tuning with the ISPs it has nothing related to either deployment or hosting . It will be a good if you first check the stuff on local and then a Dummy to check with different configurations over your ISPs so as to confirm what is the exact thing that is being blocked . then you will be able to solve your issue with ease. . .. . .. . as per your Question and my knowledge this is the Best answer i can provide Comment : Hi N.K i am basically pulling my hair out because i cant get this resolved its been nearly 2 and a half weeks now and nothing has changed just more people getting the same issue i am now in the process of completely changing servers to get a new ip what i am expecting from the community is some kind of help and just any suggestions if someone has experienced something similar with ISP s and how they resolved it .

Answer : My site http : blackwagon.com recently started experiencing some database problems . On Monday 8 17 we noticed that no PHP or Java was loading . This led us to restore our site to a previous backup taken Sunday 8 16 with Media Temple . The backup restored and went into effect Tuesday 8 18 but all of our product images http : blackwagon.com shop new-arrivals.html are not showing and are instead returning 503 errors . Upon further inspection I m seeing that it appears the images are missing from the folders they re supposed to be in but even when I attempt to re-upload the image to the correct folder I get the same 503 error and broken image icon . The only way I ve figured out how to get an image to display is to change the source patch entirely . This will work for a couple images here and there but the bulk of our catalog is coded to refer to a specific image folder and it s not exactly possible to change it . Our backend CMS is handled by a program called QubixCart and is no longer maintained . It s also incredibly PHP intensive and was coded in 2009 with no notation at all so I m having a hard time reverse-engineering it .

When you want to restrict access to only the specified directory end with a slash . For example : open basedir dir incl .. . .. . So your entry only applies to home 00000 domains not any sub directories . Comment : Are you sure the remote open basedir is being set If you run phpinfo do you see the value for open basedir you are specifying Comment : I just noticed your path : html app webroot index.php img cameron.jpg .. . Is index.php img actually a directory Comment : Checked the phpinfo and the value has definitely being changed although it looks like the master was correct in the first place . But still getting the error .

The json that I get is like this : .. . .. . In this json a ComplexCondition has both left and right as SimpleCondition s . But a general json string that I receive could be anything ranging from a SimpleCondition to any level of nesting for ComplexCondition s . I tried setting @class values in the json string but still genson could not deserialize it . I appreciate any help in deserializing this json to java using any library . Comment : I doubt that provided json can be deserialized into provided java objects by any generic library as there are no data about java class names for library to use . Probably you will have to write your own deserialization Comment : Thanks for your time @Lashane . I did the deserialization myself by having constructors in both SimpleCondition and ComplexCondition that accept a JSON object and based on the object properties in it I m making recursive calls in ComplexCondition . .. . Answer : You can register some aliases for your classes and then refer to them in your json like this : .. . .. . You also need to add get and set methods for your ComplexCondition or make its field public or provide a constructor which takes them as arguments or configure genson to use private fields . And last note the class metadata attribute must be defined before attributes that are not prefixed by @ . If you generate this json with Genson it will always respect this constraint . Comment : I tried that before posting the question but it did not work . It initializes the Condition class but does not set anything on it . So if I try to cast it to either Simple or Complex I get a ClassCastException . Could you please check that once Comment : Probably because the attributes from ComplexCondition are all private and you don t have any getter setter . I just tried by generating get and set methods for them and all works perfectly fine . BTW there is a typo in the json which makes it invalid . I updated the answer with the corrected json Comment : I do have all the getters and setters I just ignored them in the question . In fact I ve toString methods in both Simple and Complex condition classes . The result that I see for your json is columbus.service.model.Condition@7fbe847c and columbus.service.model.Condition@41975e01 where as what I m expecting is this - locality Chino and ch4 1.5 . Comment : Even if I set useRuntimeType true on the GensonBuilder I see the default string representation that basically means the object is of type Condition and not one of the subtypes . Comment : ok updated . It is not a bug but a limitation that allows Genson to be fast even when deserializing objects with class metadata .", "Question : In my Spring MVC Java application I m using Jersey REST API . I am using Jackson for JSON processing . I added Genson to my project for filtering some fields for some classes . And I am trying to use Genson only for that and remaining I want to use Jackson .

Comment : I want it as String . How can I get it Comment : If you still need to disable Genson in Jax-RS the new release includes this mechanism please see my update . .. . Answer : The up to-date documentation of Genson is hosted on github http : owlike.github.io genson . What actually happens .. . .. . To me it is not clear where you want to use Genson and how . Are you using Genson for serialization only Are you using it through jersey or directly When you do getEntity String.class Jersey asks Genson to deser the incoming json to a string . Note that in general json format does not allow strings as root values . Solutions .. . .. . 1 . Upgrade to jersey 2.X and latest Genson release in the new Jersey version when you ask the input as a string it does not delegate to MessageBodyReader correct behaviour IMO . Then you can use this string to deser to whatever type you want . 2 . Use getEntityInputStream method from ClientResponse to get the raw InputStream and convert it to a String . 3 . Another solution would be to override Gensons implementation of MessageBodyReader to not handle deser to String . .. . .. . Having multiple libs that handle JSON conversion at the same time does not sound right to me . Especially as both Jackson and Genson provide some similar features . I opened an issue https : github.com owlike genson issues 39 allowing people to disable Genson in JAX-RS apps . Update Genson 1.3 and up provide a system to disable Genson in a Jax-RS http : owlike.github.io genson Documentation Extensions jax-rs-jersey--cie app . Comment : I was only using Jackson . But in some cases I needed to remove fields from POJO while serializing . With Jackson It is more complex as it needs to add @JsonFilter annotation . If the annotation is present in a POJO class there is problem while serializing in normal way with Jackson . So I m using Genson . But that I m directly using and not with Jersey . Comment : And are there any features that you use with Jackson and don t exist with Genson I recommend you to pick solution 1 and keep only one lib if it covers your use cases . Next release of Genson will include a system to disable it in jax-rs apps . Comment : I am trying to use Genson and remove Jackson . Thanks : Comment : Use getEntityInputStream method from ClientResponse to get the raw InputStream and convert it to a String . This saved me after a few hours of hopelessly bug hunting .

I tried setting @class values in the json string but still genson could not deserialize it . I appreciate any help in deserializing this json to java using any library . Comment : I doubt that provided json can be deserialized into provided java objects by any generic library as there are no data about java class names for library to use . Probably you will have to write your own deserialization Comment : Thanks for your time @Lashane . I did the deserialization myself by having constructors in both SimpleCondition and ComplexCondition that accept a JSON object and based on the object properties in it I m making recursive calls in ComplexCondition . .. . Answer : I came up with this solution . If anyone can give a better solution I would be happy to accept it .", "Question : I m running into the following problem when trying to execute a POST call using Jersey and Genson : .. . .. . ... . com.owlike.genson.JsonBindingException : No constructor has been found for type interface Animal ... .

Thank you in advance . : : : : SOLUTION : : : : : .. . .. . In case anyone runs into this : .. . .. . I removed genson dependencies completely as suggested below . Only used jackson annotations and it seemed to work . Also I removed the @JsonProperty from the name attribute in the Dog.java . Thank you : : .. . Answer : I think you mean I m trying to use one of the interface implementations when deserializing my objects . .. . .. . Your problem .. . .. . If it is what you mean then the short answer is it can not work like that . 1 . I see you are using Jackson annotations Genson does not see use those annotations jackson and genson a two different libraries . 2 . Based on the json stream the sample input you provided Genson has no way of knowing to which concrete class to bind . .. . .. . Some possible solutions would be .. . .. . If you use the same pojos animal dog etc and Genson on both ends the code that will post the data to the server and the server then using a Genson instance with useRuntimeType and useClassMetadata enabled on both ends should work . It would be the easiest solution . The class metadata mechanism during serialization writes in the json object as first entry the class name of the concrete type during deserialization Genson looks for this first attribute with key @class to extract the concrete class name . In your case if you are able to produce a json of the form animals : @class : com.test.Dog name : Unno then genson would deser it to the correct type . Note that you can also register aliases for types so you could just write dog instead of the full class name . More details in the documentation http : owlike.github.io genson Documentation UserGuide polymorphic-types . As you have those Jackson annotations to give type hints then you could also use jackson to handle the deser note that the input json would not work with this configuration as it does not seem to contain the informations defined via the annotations . In this case you should not use Genson to handle the ser de with jersey as jackson and genson do both the same job . Comment : Thanks eugen . I meant deserialization I have corrected it . I would prefer to stay with Jackson only . For now I will remove the Genson stuff and try using jackson . How would the JSON look like then can you comment Comment : I guess it should contain some property named type and having as value dog . Similar to the behaviour with @class in genson except that maybe the order does not matter . Comment : Do you mean this : animals : type : dog name : Unno Comment : Yes I think so as you have set property type in JsonTypeInfo . You might also want to read jacksons documentation about those annotations as I am not 100 sure of the meaning . Comment : eugen that is almost working . Now I get a response back however the response looks like this : animals type : dog name : null even though I m passing in the name in the input json .

EDITED : I did t get success with genson and use gson now . Gson works fine for me .

Comment : I would use circe or Argonaut both are high performance json parsers that do not use reflection at all they are also idiomatic scala unlike genson or gson .. . Answer : Can you try to use scala.Array in your code without Genson . Just to make sure it is present . Then try to use scala.Array and at the same time use Genson . If it works then this means that scala.Array is probably excluded by proguard . If this doesn t work I suspect that the classloader used by Genson doesn t see the Array class . In that case try this : Comment : Eugen thanks for help . I have Array objects in my code so it is present in classpath . With builder exception is the same .

The problem with this is that the client is parsing the string I need it to be sent as it is . I m sending something like name : Foo and the client is converting it to name : Foo . If I change the type to PLAIN TEXT it sends the request correctly but I need to send it as application json . Comment : When you say the client is converting where are you seeing the conversion On the server Comment : I m sniffing it with wireshark . .. . Answer : So yes Genson will try to encode your string as a literal json string . In this case it is maybe not what you would want but more generally it is what people would expect : serialize java string as a json string . The solution I see is too extend GensonJsonConverter https : github.com owlike genson blob master genson src main java com owlike genson ext jaxrs GensonJsonConverter.java and override isWritable to return false when the input type is string . Then just register it . That should work . I ve opened this issue https : github.com owlike genson issues 73 so it can be added as a more flexible feature . Comment : Wouldn t a standalone literal JSON string always be invalid JSON It should be a JSON object or JSON array right So if type is application json and data is of type String wouldn t it be better to always send as is I haven t seen Genson code but I meant when it is being intercepted upon a post or put .

After that I try to get the values in the Catalog object but get a NullPointerException because it seems to be empty . I think the deserialization has a problem with the d object in the JSON but how do I fix this Any help would be appreciated . .. . Answer : The problem is that you havee 2 constructors one with no arguments and the other with the arguments . Genson in this situation picks the empty constructor . And as the properties are not visible and there are no setter then it will not populate the values . So if you want Genson to use a specific constructor then you must annotate it with @JsonCreator . BTW you can remove the JsonProperty .. . on the arguments if you configure Genson with this option : .. . .. . The other option would be to tell Genson to use private properties by doing this : .. . .. . In that case you don t need the annotations on the constructor as Genson will use the no arg one . I recommend you the first option . Comment : Thanks for your answer can t currently try your tips but will tomorrow when I m back at work . Comment : Hey I tried your tps by specifying the right constructor but the values of the catalog are stillt not created . Comment : Oh I see that you have your catalog object is not the root of the json . Can you change your json to not have d : results but just results Otherwise if all your incoming jsons will use d as key you can configure Genson with wrapRootValues d d http : owlike.github.io genson Documentation Configuration Comment : @MarkusWilhelm does this work for you You can also use the JaxbBundle with wrapRootValues enabled and @XmlRootElement d on your Catalog class .

Here you can find some examples on how to customize Genson with Jaxrs http : owlike.github.io genson Documentation Extensions jax-rs-jersey--cie . Note that if you ever want to deserialize to a ResponseObject then you will probably have troubles as in the json there is no information about what is the concrete type of base object .

Number s .. . Arrays .. . Enum classes .. . .. . The SSCCE below demonstrates roughly what I am trying to achieve : .. . .. . Numbers and Arrays worked well out-of-the-box but the enum-class is providing a bit of a challenge . In this case the serialized JSON form would have to be IMO a JSON object including a : .. . .. . type member .. . value member .. . .. . Looking at the EnumConverter class I see that I would need to provide a custom Converter . However I can t quite grasp how to properly register the Converter so that it would be called during deserialization . How should this serialization be solved using Genson .. . Answer : Great for providing a complete example First problem is that DTO doesn t have a no arg constructor but Genson supports classes even with constructors that have arguments . You just have to enable it via the builder with useConstructorWithArguments true . However this will not solve the complete problem . For the moment Genson has full polymorphic support only for types that are serialized as a json object . Because Genson will add a property called @class to it . There is an open issue https : github.com owlike genson issues 64 for that . Probably the best solution that should work with most situations would be to define a converter that automatically wraps all the values in json objects so the converter that handles class metadata will be able to generate it . This can be a good enough solution while waiting for it to be officially supported by Genson . So first define the wrapping converter .. . .. . Then you need to register it with a ChainedFactory which would allow you to delegate to the default converter this way it works automatically with any other type . The downside with this solution is that useClassMetadataWithStaticType needs to be set to true ...but well I guess it is acceptable as it s an optim and can be fixed but would imply some changes in Gensons code the rest still works . If you are feeling interested by this problem it would be great you attempted to give a shot to that issue and open a PR to provide this feature as part of Genson .

Note that I think you can also use @JsonProperty annotation on the fields you want to include instead of including them via the GensonBuilder .

Answer : syncdb doesn t overwrite the database data it just add the database tables that you need for the application you installed in your project .

Settings.py looks like this : .. . .. . As you can see I have two databases both PSQL 9.2 default used for app1 application and app2 used for app2 application and I ve defined such 3 routers 1 . for authentification 2 . for app1 model and last for app2 model .

I discovered myself in a similar situation earlier this year and the least time-consuming and most effective solution was to implement a database join migration script . Comment : Do you mean using just one database which is shared between all applications If it was possible I d love to use just 1 postgres DB with different schemas inside 1 for each application but it doesn t work . I truly need application data separated . Whole idea is create a web portal default app as a wrapper with all users passwords etc and other apps will be added independently app2 is actually attendance system app3 a ticket-system .. . Any Ideas Comment : Need to clarify some terminology for me.. . are you referring to multiple applications within the same Django project or multiple-projects themselves Comment : Well as far as i know two django projects can t speak to each other . That s why I wanted to create one Django project which will have different applications inside default app1 app2 - web attendance app3 - ticket-system .. . . I want to have the system as independent as possible but these parts app1 app2 app3 have to be able to communicate actually app2 app3 have to authenticate using app1 - which led me to use 1 Django projects with multiple apps each having own database .

Answer : What helped me is this post : http : diegobz.net 2011 02 10 django-database-router-using-settings .. . .. . Solution is this : .. . .. . 1 . using just one Router and this router will take care of application 2 - router app2.router.App2Router not any routers for default database . Routers for default database works fine just as it is . 2 . Alter that app2.router.App2Router to look like the code in that link in the beginning of the post provided . Doing just step 1 led to creating auth and django tables by running syncdb correctly but unfortunately ALL MODEL tables were created to default database ie . also tables from app2 . Altering app2.router.App2Router made everything work . 3 . Alter settings.py to look like this : .. . .. . DATABASE ROUTERS app2.router.DatabaseAppsRouter .. . .. .

Answer : makemigration always creates one migration file having all the changes . So when you run makemigration for first time it tries to find the previous migration file . if not found it creates one initial migration file . And when it tries to apply it to the db it finds the relation already exists . And thus throws error .

Answer : I did leave something out that I didn t think was relevant but is totally relevant . This application has multiple databases defined .

However when my user didn t have permission on the other database syncdb would fail . It didn t indicate which database it was trying to access . Running . manage.py reset db from django-extensions worked fine as well before I made sure that the user had permissions on all databases . I would assume then that there is a bug in syncdb . After more looking into this I might have to report a bug to Django .", "Question : I ve written a pretty simple Django application called django-locality http : github.com rfkrocktk django-locality which takes the headache out of working with countries and territories . It provides a lot of initial data for countries and territories . I just the 0.1 release up to PyPI and installed it in my project which I m currently working on . I basically created it out of a need I found in my original project . When I ran syncdb however it didn t install any of my fixtures from locality . In the output it printed No fixtures found and no rows were added to the database though the tables were generated . Is there a reason why Django is missing my initial data My data lives at locality fixtures initial data.json and installs just fine if running it from it s own dedicated project . As I m using setuptools to manage dependencies would it make a difference if I downloaded it as a zipped egg vs . a simple directory layout .. . .. . Initially it seems that my JSON wasn t being included in the egg and this is why syncdb didn t work . Now I ve fixed that problem but syncdb is still failing to find any of my fixtures . You can download the egg to see for yourself here http : pypi.python.org pypi 3aaction display name django-locality version 0.1.1 . I can t think of any reason why Django would be missing the initial data . You can also view the repository http : github.com rfkrocktk django-locality on GitHub . Why isn t Django seeing the fixtures .. . .. . When I run syncdb -v 2 I do see that Django sees the egg and looks for the fixtures : .. . .. . Is it possible that Django doesn t know how to read from eggs .. . Answer : It looks like your setup.py does not include the initial data.json as package data : http : docs.python.org distutils setupscript.html installing-package-data This means when you install from PyPi you won t get the initial data.json file in your distribution . I personally find it easier to use source distributions sdist for Django apps . In that case you can list non-Python files which need to be included in the MANIFEST : http : docs.python.org distutils sourcedist.html Comment : So in my example what should I do I ve tried including a MANIFEST and have tried adding package data to my setup file but it s still not including it . Comment : Nevermind figured it out by elimination Comment : It still seems like it s not working . I ve determined that it s working it s including the fixtures directory and json in the egg but it s still not including it when running syncdb .", "Question : I am trying to install graphite on a linux node in a automated fashion .

Answer : You could take a look at the page load-time and see if that s any different on iOS . Check the source report to see if iOS traffic is typical . Also look at the volumes .

Searching other questions on stackoverflow and elsewhere it seems like most other people prefer the 9.3 behavior . However I need the 9.2 behavior of shrink-to-fit . So my question is : does anyone know how to get the same shrink-to-fit behavior in 9.3 And does anyone know if this change is intentional or a bug that s going to be fixed in subsequent releases My test code can be found at https : github.com nsolter NSWebViewShrinkTest specifically https : github.com nsolter NSWebViewShrinkTest blob master NSWebViewShrinkTest ViewController.m .. . Answer : I filed a bug report with Apple and this is the response : .. . .. . No we don t want to maintain shrink-to-fit behavior . The workaround is to use a viewport meta tag that correctly describes the width of the content . I tried this out . If in the viewport tag you specify a width of the actual width of the html after it s rendered it will display properly on your device width . In my example above with a table width of 700 if you specify : meta name viewport content width 700 shrink-to-fit YES .. . .. . Then the page will display without horizontal scrollbars . Note that you can t specify an initial-scale viewport property though . Then it doesn t display with the proper width . This is obviously less than ideal because you generally don t know what the width of your rendered html will be until you render it . My current solution is to render it once with width device-width then render it again with width X where X is the actual width of the rendered page the first time .", "Question : I have the following block of code in Swift 2.0 that I m using to add 3 days from the current date to retrieve the weather data for that specific day .

I found this well written article https : www.depesz.com 2015 04 02 waiting-for-9-5-allow-foreign-tables-to-participate-in-inheritance that explains everything on how to do it from scratch . My question is how to reduce the needed migration of data to a minimum . We have this 100+ GB table now that should become our first shard . And in the future we will regulary add new shards . At some point the older shards will be moved to another tablespace on cheaper hardware since they become less important . My question now : Is there a way to ALTER an existing table to be a foreign table instead .. . Answer : No way to use alter table to do this . You really have to basically do it manually . This is no different really than doing table partitioning . You create your partitions you load the data . You direct reads and writes to the partitions . Now in your case in terms of doing sharding there are a number of tools I would look at to make this less painful . First if you make sure your tables are split the way you like them first you can use a logical replication solution like Bucardo to replicate the writes while you are moving everything over . There are some other approaches parallelized readers and writers that may save you some time at the expense of db load but those are niche tools .

Comment : You ll have to enforce the constraint on the remote side for now . There s been discussion of supporting check-constraints on foreign tables but the problem is that Pg has no way to know if they re valid or to enforce them on the remote data . The planner makes assumptions based on check-constraints that could cause it to generate an incorrect plan if the check-constraint doesn t actually match the data in the foreign table . So for now it s not supported . Comment : @CraigRinger What about using user defined function to check the constraint manually Wouldn t this be a good solution to this problem Example : CHECK someFunction field IS TRUE", "Question : The Citus documentation https : www.citusdata.com docs citus 5.0 reference user defined functions.html master-get-table-metadata for the master get table metadata function states : .. . .. . part storage type : Type of storage used for the table .

Used by distributed file fdw tables .. . .. . So my question remains : is it possible to use other foreign data wrappers such as mysql fdw .. . Answer : Creating distributed foreign tables has only partial support right now within Citus . Let s take your example : .. . .. . You can now distribute this using : .. . .. . And create shards using : .. . .. . However each shard created on the worker node will inherit the same options as the master node . Thus each shard will point in this example to dbname constructor and foreign table audit . There would be limited value in creating such a distribution since even though Citus will issue parallel queries they will all again be sent to a single node and table . To construct a more useful example let s say you already have some let s say 8 sharded MySQL tables e.g . audit 1 audit 2 .. . audit 8 . You can construct the same table as above and create a distributed setup like so : .. . .. . And create shards using : .. . .. . You would now need to log into each Citus worker node and update each shard to point to it s relevant MySQL shard . e.g : ALTER TABLE audit 100208 OPTIONS SET table name audit 1 .. . .. . If you have tables spread across multiple nodes or databases you d need to manually create specific servers for each foreign node on every Citus worker node . There are caveats here to be careful of . For one we marked the distribution as append because we don t know the underlying distribution of the foreign table . If you use hash you may get wrong partition pruning via Citus . There may be other caveats too as this isn t a use-case we actively support or have tested . From a historical perspective we primarily used this as a proof-of-concept to try reading flat-files spread across multiple nodes . Edit Adding responses to the other questions by Eugen . Also please note such Q A is best suited for the mailing list here : https : groups.google.com forum forum citus-users .. . .. .

Right click on your download and use the extraction tool to extract and save the 3 updated files . 2 .

Answer : You ve already chosen the AT90CAN128 whose standout feature compared to other AVR processors is support for the CAN bus . There really is not a better choice than CAN for an automotive application with your data rate and noise immunity requirements . If you march in to an automotive customer with anything other than CAN you ll end up spending all your time defending the decision not to use it . With that said for noise immunity in a hostile environment like a car you ll need a bus using differential signaling . That rules out i2c or SPI which is unfortunate because they meet your other requirements . RS-485 would be workable as @Andrew Edgecombe points out . If you re not building a commercial product but instead building something for your own use to put in the engine compartment you can probably get by with USB . USB will make it easy to interface with a laptop in the passenger compartment and though it isn t designed for high-noise environments it is differentially signaled at a reasonably high voltage .

Answer : Hi To specify the CAN bus first determine which CAN bus speed you will use then the CAN bus ID length . If it is a standard OBD-II based CAN system e.g . 11bit ID 500 kbaud then use ATSP6 to set this protocol . Then use ATSHxxx to set the target ID e.g . ATSH7E0 The use ATCMxxx and ATCFxxx to set the CAN mask and filter to handle your receive frame filters .

Answer : For all out reliability you can t go past CANbus but then that was sort of implied by your choice of processor Depending on what you want to interface to this can be very simple - the base level protocol is quite straight forward . But if you want to talk to any other non-proprietary devices you ll have to implement the higher protocols eg . CANopen . But if CANbus isn t appropriate then I would recommend RS485 or RS422 depending on your topology . If all you re trying to achieve is point-to-point communications it s identical to RS232 . you ll have to put your own protocol layer on top if you re trying to support multidrop comms though .", "Question : I ve been fiddeling around with a bluetooth elm327 device I bought a few months ago and am able to get standard obd infos like vin rpm speed etc .

Answer : On many modern vehicles there are actually multiple CAN buses controlling the numerous functions needed by the car . Some of these CAN buses are high-speed for important systems like engine control and some are low-speed for less critical functions such as climate control or in your case diagnostics through the OBD2 port . These multiple CAN buses are usually interconnected through a gateway device in the car that arbitrates which CAN messages can be sent between buses . This is a safety net that prevents lower priority CAN buses from interfering with the more critical CAN buses . In an example case the CAN bus used for engine control may be able to communicate with the radio CAN bus so that the radio volume gets increased when the engine is revving to higher RPMs for comfort reasons . This would likely be a one-way connection though the gateway though as it would be in the interest of safety to not allow the radio s CAN bus to send signals back to the engine this could lead to potential problems if using aftermarket radios for example . As a result-of everything mentioned above a connection to the OBD2 port s CAN lines most likely will not have full access to the complete CAN network on your car . One way to confirm this would be to look for the Factory Service Manual for your particular vehicle to see how the CAN bus es are setup for your car there are actually quite a few cars that operate on only a single CAN bus in order to cut costs . Keep in mind that as an alternative to using the OBD2 port you can always tap directly into the CAN bus that you are interested in . For example if you remove the radio from your car to expose the radio harness you can usually tap directly into the CAN lines for the radio bus with the correct equipment .

For future reference you can make a flag to the moderators to migrate a question . .. . Answer : The CAN shield can be both a receivers and a transmitter you shouldn t need two of them unless you are bridging two networks together . Unfortunately operating the windows is not something for which there is a standard message . And indeed the window controllers may actually be on a LIN http : en.wikipedia.org wiki Local Interconnect Network bus not CAN . I m not sure there is a LIN shield but it s a relatively simple physical layer http : www.eetimes.com document.asp doc id 1272421 chip and a UART so you should be able to rig something up . Then you will have to reverse engineer the messages.. . If you can find out from a workshop manual what the CAN LIN buses look like you should be able to find somewhere to tap into the right bus . Then monitor the bus and operate the window switch to see if a new message appears or if some particular bits change in a regular message . There will often be sequence counters and checksums within the messages which you will also have to understand in order to correctly replay the appropriate message . Comment : Ok so the CAN BUS doesn t have access to the car s windows what can it control can the CAN BUS control the headlights wipers or the airconditioner for example and what is the signal which will control it Thanks Comment : It might control the windows it might not . In any case there are no standard commands to control anything on the car . There are standard OBD diagnostic commands to interrogate ECUs but the control and sensing mechanisms are different on every platform and at the whim of the vehicle manufacturer so you ll have to reverse engineer it . And only on a fairly modern vehicle will things like the aircon wipers etc be controllable I m afraid .", "Question : I apologize ahead of time if this seems to similar to another question or if it seems like it has already been answered .

I use ELM327 based OBDII to Bluetooth adapter to monitor the CAN traffic in the Passenger Vehicle . Said otherwise our intent is to deploy EML327 as a CAN2BT Dongle for CAN message Rx purposes . I would love to use the Monitor All feature to receive all messages in the Vehicle not just Diagnostics typically done over OBDII protocols . I intend to use AT-MR and AT-MT interfaces supported by ELM327 to selectively listen to messages our Application is interested in . The issue I have is that in the Lab the ELM327 is hooked to a CANCaseXL and in AT-MA or AT-MR or AT-MT modes the ELM327 does not send any acknowledgement . Because of this missing ACK though the CANcaseXL is transmitting at compatible Baudrate Transmit errors drive the CANcaseXL into Error state . Is there a way to send a sequence of Proprietary AT commands to put the ELM327 into a mode where it is not communicating over OBDII Diagnostic protocols instead listening to Raw CAN Bus activity with due ACKs Need communities kind help in this regards .. . .. . Thanks and Regards Kishore .. . Answer : Try the CSMx command . See page 15 of the ELM327 datasheet : .. . .. . CSM0 and CSM1 CAN Silent Monitoring off or on .. . .. . The ELM327 was designed to be comptetely silent shile monitoring a CAN bus . Because of this it is able to report exactly what it sees without colouring the information in any way . Occasionally when bench testing or when connecting to a dedicated CAN port it may be preferred that the ELM327 dows not operate silently ie generates ACK bits etc . and this is what the CSM command is for . CSM1 turns iton CSM0 turns it off and thedefault value is determined by PP 21 . Be careful when experimenting with this If you should choose the wrong baud-rate then monitor the CAN bus with the silent monitoring off you will disturb the flow of data . Always keep the silent monitoring on until you are certain that you have chosen the correct baud-rate .", "Question : null .. . Answer : I m developing a test bench for automotive purpose mainly powered steerings . I Can simulate it and turn it on and diagnose error codes and info about it . I did success on many units but got problems with other ones . The problem comes when the units I m trying to simulate got a multiplexor ecu . I explain this a bit . For example Fiat G.Punto in my test bench my diagnostic tool talks directly to the unit so I can turn it on and diagnose it with appropiate data . But in Peugeot 207 for example powered steering does not communicate directly it s wired to a bridge multiplexor AKA BSI BODY in automotive and when you try to diagnose the tool does directly against the BSI that is what got the info through other canbus line so it cant find the powered steering module .

For future reference you can make a flag to the moderators to migrate a question . .. . Answer : 1 . CAN bus is a communication protocol like RS485 but more reliable . It does not control anything itself . 2 . If windows headlights or other devices are controlled with I O and I O is communicating with CAN bus then you might be able to control windows headlight etc . 3 . CAN bus shield for Arduino has Microchip MCP2515 CAN controller with MCP2551 CAN transceiver so you do not need 2 of them .

What do you mean by different shields and different languages As long as they use the same protocol it can be a general purpose one such as serial i2c spi can ethernet or a custom one you wrote and have the same electrical specifications which is usually not true for 5V arduino boards since rPI is a 3.3V device - you will need voltage translators or post a better question they will work .

GOOGLE - and write raspberry-pi arduino can-bus . . Anyway why CAN bus there are easier to use protocols serial i2c .. . which benefit from direct hardware support .

Answer : As long as both shields comply with CAN spec and the software in both ends uses the same configuration bitrate CAN message structure CAN IDs there should be no problem in using different platforms and different languages to communicate between them .

And we program receiver to tell it that you should be interested in value 5 .. . Answer : The software in the CAN node must decide what message IDs it is interested in based on the network specification which is usually some kind of document or other electronic representation of which messages contain what sorts of information . If a message arrives that is of no interest it simply does not process it and the software returns to what it was doing just before the message arrived assuming interrupt driven CAN handling . Some CAN controllers ie the part of the chip which does the CAN protocol transmission and reception have message filtering which means that uninteresting messages can be dropped before they reach the software . Other controllers have message filtering which can be set to accept only a single message ID in a particular message box and these can be configured to accept the messages you are interested in . Again other messages are dropped . Some controllers have both filters and message boxes .", "Question : How a CAN Bus controller decides based on message identifier that this particular message belongs-to it Is it like the receiver already know that if identifier has suppose value 5 then its for me .

Answer : At the CAN protocol level all nodes in a CAN network are equal and make a decision about whether to process a message or not .

How you decide which message to process depends on what you are trying to do and the higher level protocol in use over CAN . In principle you mask out the ID bits that are relevant and then test them to see whether the message should be processed .

Comment : jacobrothstein.com entries delayed-job-and-monit http : www.jacobrothstein.com entries delayed-job-and-monit Not sure how good it is though I haven t tried this approach .. . Answer : I had to combine the solutions on this page with another script https : cloud-support.engineyard.com discussions questions 230-running-delayed job-workers-solved made by toby to make it work with monit and starting with the right user . So my delayed job.monitrc looks like this : Comment : not working it says : bin su : su : must be run from a terminal", "Question : Are there any examples on the web of how to monitor delayed-job with Monit http : mmonit.com monit Everything I can find uses God http : god.rubyforge.org but I refuse to use God since long running processes in Ruby generally suck .

Answer : I don t know with Monit but I ve written a couple Munin plugins http : helderribeiro.net p 87 to monitor Queue Size and Average Job Run Time . The changes I made to delayed-job in that patch might also make it easier for you to write Monit plugins in case you stick with that .", "Question : I d like ExceptionNotifier to send out an email when an exception happens in a delayed-job just like for other exceptions . How can I achieve that Comment : Interesting question in looking I came across stackoverflow.com questions 4104093 http : stackoverflow.com questions 4104093 exception-notification-for-delayed-job and groups.google.com group delayed-job browse thread thread http : groups.google.com group delayed-job browse thread thread 646314145a69360b fwc 1 pli 1 Comment : Yep I ve seen both of those but I think these solutions only work with Rails 2 . .. . Answer : I do this with Rails 3.2.6 delayed-job 3.0.3 and exception-notification https : rubygems.org gems exception-notification 2.6.1 gem .. . .. . It s probably a good idea to load this code in all environments to catch errors after bundle update etc before they reach production . I do this by having a config initializers delayed job.rb file but you could duplicate the code for each config environments environment . Another tip is to tune the delayed-job config a bit as default you may get a lot of duplicate exception mails when job fails . Update I had some problems with the delayed-job daemon silently exiting and it turned out to be when ExceptionNotifier fails to send mail and no one rescued the exception . Now the code rescues and log them . Comment : I d recommend using the official exception-notification gem at github.com smartinez87 exception-notification https : github.com smartinez87 exception-notification Comment : Ah ok will update to that . I was using the rails3 gem as there seamd to be some rails 3 issues with the official version at the time . Comment : +1 This approach works with Rails 3.2.6 Delayed Job 3.0.3 and Exception Notification 2.6.1 . Initially I thought adding an error method using the built-in hook would be a cleaner approach but that would have to be defined for each job class and defining it generically for PerformableMethod didn t work due to how delegate is used . Comment : I ve added a : data : job job to the method call so that I have a bit more details Comment : Has anyone gotten this working Rails 4" ] }

I am able to connect to the OData service and to read data . As soon as I try to Create Update Delete data I get the 403 - Forbidden Error . Actually my user has the required rights to execute all of the mentioned actions I created data using the SQL command-line in HANA Studio . When I try the same with the SYSTEM user I get the same result . .. . Answer : I am guessing that your OData service is defined to not allow modifications of the data . From the SAP HANA Developer Guide http : help.sap.com hana SAP HANA Developer Guide for SAP HANA Studio en.pdf : .. . .. . By default all entity sets and associations in an OData service are writeable that is they can be modified with a CREATE UPDATE or DELETE requests . However you can prevent the execution of a modification request by setting the appropriate keyword create update or delete with the forbidden option in the OData service definition . The following example of an OData service definition for SAP HANA XS shows how to prevent any modification to the table myTable that is exposed by the OData service . Any attempt to make a modification to the indicated table using a CREATE UPDATE or DELETE request results in the HTTP response status 403 FORBIDDEN .", "Question : I m trying to implement simple product catalog using HANA XS Javascript .

Missing is how to map from a SQL Type to Edm.Boolean anyone know how .. . Answer : In the SAP HANA developer guide SPS 07 it also says that the OData implementation in SAP HANA XS supports only those SQL types listed in the mentioned list table . Therefore Edm.Boolean is not supported . A workaround could be to use Edm.Byte instead of Edm.Boolean which is mapped to the TinyInt HANA SQL Type . If you only want to have a true false or 0 1 value I think the TinyInt SQL Type is the closest you can get to a Boolean .

So long as the browser remains open the session remains live . One trick I have is to close the browser . Another trick is to delete active login sessions in the browser-history . Both force me to re-login very nice . But these are so lame because they rely on a user action . I am sure SAP HANA is wiser than that . I will greatly appreciate your help . Is there a different parameter to set I am on SP07 . I run xsengine as a separate process . Thanks a lot . .. . Answer : Firstly You shouldn t be using Basic Auth at all .

You should look at using the other methods of login . I assume you are trying to authenticate yourself as a HANA user . For this you can use the super simple Form based authentication . To use this you just have to include the following in your .xsaccess file at the root of the package : .. . .. . This would route you to a Login page that comes with HANA where you can login . Post successful login it will redirect you back to your application . So the flow would be something like this : .. . .. . You visit some app index.html for which you need to be authenticated by HANA . You are redirected to sap hana-xs formLogin login.html where you will login as a HANA user .. . You are redirected back to some app index.html now authenticated as the user you logged in as . When you use something like this a proper session is maintained . At this point in time your setting of xsengine httpserver sessiontimeout will work .

I have the working but the problem is that every time I type a character both templates get updated which means even the search control itself gets reset every time .

I have seen other recommendations on the web being basically : .. . .. . Use an engine to precompile the template eg Grunt-inline-template-compile https : www.npmjs.com package grunt-inline-template-compile This is useful for when you have your template strings inline mine are all in the actual html in tags so this wouldn t be possible without drastic content moving around .

Answer : Try setting the Content-Security-Policy header to unsafe-eval for scripts from your domain as a temporary workaround . http : content-security-policy.com Then move to a template-engine such as Handlebars as soon as possible .

Answer : From the fine manual http : underscorejs.org template : .. . .. . template .template templateString data settings .. . .. . .. . If ERB-style delimiters aren t your cup of tea you can change Underscore s template settings to use different symbols to set off interpolated code .

Answer : I m using Underscore templates and would like to leverage their HTML escaping functionality while allowing some tags to still come through . Looking over their implementation though it appears that it s an all-or-nothing situation : with escaping turned on all HTML entities are escaped .

The best way to get around this limitation seems to be overriding Underscore s .escape and .unescape https : github.com jashkenas underscore blob a315e9f4473005a8310540b16d565519a9556106 underscore.js L1191-L1198 but that actually seems like a terrible idea and not something I want to do .

Answer : It s a known challenge as far as I see to have a job that runs an external application script in Async mode and reflect that properly on build-pipeline-plugin overview .

Answer : I ran into this myself today and through some bruteforce I ve figured out both how to resolve it and potentially why . Probably best to start with the why : .. . .. . Jenkins has a paradigm where all jobs can be interrupted paused and resumable through server reboots . To achieve this the pipeline and its data must be fully serializable - IE it needs to be able to save the state of everything . Similarly it needs to be able to serialize the state of global-variables between nodes and sub-jobs in the build which is what I think is happening for you and I and why it only occurs if you add that additional build step . For whatever reason JSONObject s aren t serializable by default . I m not a Java dev so I cannot say much more on the topic sadly . There are plenty of answers out there about how one may fix this properly though I do not know how applicable they are to Groovy and Jenkins . See this post http : stackoverflow.com a 25326211 420787 for a little more info . How you fix it : .. . .. . If you know how you can possibly make the JSONObject serializable somehow . Otherwise you can resolve it by ensuring no global-variables are of that type . Try unsetting your object var or wrapping it in a method so its scope isn t node global . Comment : Thanks That s the clue I ve needed to solve this .

Answer : Linq to Objects The term LINQ to Objects refers to the use of LINQ queries with any IEnumerable or IEnumerable collection directly without the use of an intermediate LINQ provider or API such as LINQ to SQL or LINQ to XML . You can use LINQ to query any enumerable collections such as List Array or Dictionary . The collection may be user-defined or may be returned by a .NET Framework API . In a basic sense LINQ to Objects represents a new approach to collections . In the old way you had to write complex foreach loops that specified how to retrieve data from a collection . In the LINQ approach you write declarative code that describes what you want to retrieve . ref : http : msdn.microsoft.com en-us library bb397919.aspx .. . .. . Linq to Entity LINQ to Entities provides Language-Integrated Query LINQ support that enables developers to write queries against the Entity Framework conceptual-model using Visual Basic or Visual C . Queries against the Entity Framework are represented by command tree queries which execute against the object context . LINQ to Entities converts Language-Integrated Queries LINQ queries to command tree queries executes the queries against the Entity Framework and returns objects that can be used by both the Entity Framework and LINQ . The following is the process for creating and executing a LINQ to Entities query : Ref : http : msdn.microsoft.com en-us library bb386964.aspx", "Question : I usually use the term entity to represent a business data object and in my mind the linq-to-entities and linq-to-objects were the same .

Answer : That is definitely not the case . LINQ-to-Objects is a set of extension-methods on IEnumerable T that allow you to perform in-memory query operations on arbitrary sequences of objects . The methods accept simple delegates when necessary . LINQ-to-Entities is a LINQ provider that has a set of extension-methods on IQueryable T . The methods build up an expression tree which is why delegates are actually passed as Expression s and the provider will build up a SQL query based on its parsing of that expression tree . As an example consider the following queries : .. . .. . The first query is will build up an expression tree consisting of a select and a where with the two lambdas actually considered as LambdaExpression s . The LINQ-to-Entities provider will translate that into SQL that both selects and filters . The second query inserts an AsEnumerable which will force the remainder of the query to use LINQ-to-Objects . In that case the provider will generate SQL based on only the selection return all those records from the database and then the filtering will occur in-memory . Obviously that s likely going to be much slower . Comment : is there any way to filter on both conditions for a linq to object query or is it always narrowing down to the first action before processing the next Comment : It depends if you just want to get all the records from a database and then perform actions on them in memory you can put the AsEnumerable before the Select and then do what you want . In general though it s a better idea to keep things separate . If you have an IEnumerable T then you ll be using LINQ-to-Objects . If not then the database will likely be more efficient .

Cheers", "Question : Any advice on when DataTable.Select http : msdn.microsoft.com en-us library system.data.datatable.select.aspx should be used versus LINQ Select http : msdn.microsoft.com en-us library system.linq.enumerable.select.aspx when dealing with an in-memory DataTable I find LINQ syntax easier and more powerful but I m not sure if there are performance or other issues which make a DataTable select preferable . I m using a third party API that provides a DataTable that has been pre-populated from the database . I need to filter that further in-memory . .. . Answer : Hmm are you comparing datasets with LINQ to SQL http : msdn.microsoft.com en-us library bb425822.aspx If you are then I d say just ditch datasets and go with L2S . DataTable.Select assumes you ve already populated the datatable with data . This can lead to bad designs where you load more data than you need just to filter in the client . Get SQL Server to do your querying for you and work on the resultset it gives you . L2S will read from the database only when you iterate the collection so it s much easier to formulate your queries before hitting the database . LINQ to SQL introduces some debugging overhead because it can be awkward to get the dynamically-generated SQL out of it whereas in datasets you are supplying the SQL in the first place but in almost all other situations it s far more elegant . The deferred loading http : msdn.microsoft.com en-us library bb425822.aspx linqtosql 5Ftopic15 functionality is especially useful . If you re not working with a database then I d still prefer LINQ specifically known as LINQ to Objects http : msdn.microsoft.com en-us library bb397919.aspx in this scenario over datasets . The syntax is just much easier and because there are no magic strings i.e . SQL statements then it s easier to test and you get compile-time warnings for typos etc . Comment : Thanks for your answer . I should have made clear that I don t have interaction with the database . I ll update the question . Comment : Ahh fair enough . I ve updated my answer on that basis .", "Question : I have 2 lists . 1 is a collection of products . And the other is a collection of products in a shop .

Thanks Comment : Thanks everyone for there comments I have it working now.. . Thanks again. . Answer accepted . .. . Answer : For LINQ-to-Objects if listOfProducts contains many items then you might get better performance if you create a HashSet T containing all the required names and then use that in your query . HashSet T has O 1 lookup performance compared to O n for an arbitrary IEnumerable T . For LINQ-to-SQL I would expect hope that the provider could optimise the generated SQL automatically without needing any manual tweaking of the query . Comment : Nice trick for linq to object . Comment : Thanks . It was really helpful .", "Question : I found an example in the VS2008 Examples http : msdn2.microsoft.com en-us bb330936.aspx for Dynamic LINQ that allows you to use a sql-like string e.g .

Answer : You could add it : .. . .. . The GetPropertyValue function is from Kjetil Watnedal s answer http : stackoverflow.com questions 41244 dynamic-linq-orderby 41262 .. . .. . The issue would be why Any such sort would throw exceptions at run-time rather than compile-time like D2VIANT s answer . If you re dealing with Linq to Sql and the orderby is an expression tree it will be converted into SQL for execution anyway . Comment : GetPropertyValue mehotod will be executed for all elements it s bad solution . Comment : OrderBy don t maintain the previous order", "Question : Let s say we have a sorted collection such as SortedSet http : msdn.microsoft.com en-us library dd412070.aspx or SortedList http : msdn.microsoft.com en-us library system.collections.sortedlist.aspx with many 10M+ elements . Lots of querying is happening so performance matters . From runtime comparisons I m under the impression that LINQ to Objects doesn t take advantage of the sorting therefore not taking advantage of potential performance gains . First example - counting the elements in a range : .. . .. . Not exactly sure what LINQ to Objects does here internally worst case it s checking every single element which would be O n . The can be done a lot faster by taking advantage of the sorting with a binary-search for the lower and upper bound in O log n . Second example - SelectMany over list of sets : .. . .. . If LINQ to strike SQL strike Objects were to take advantage of the sorting it could effectively zipper-merge all the sorted sets into one large sorted list in O n . The .OrderBy on the result could then be ignored as the list is already sorted . Instead SelectMany concatenates all the sorted sets into one large now unsorted list which will required another O n log n sort . This can easily be verified by removing the .OrderBy and observing the order in which the elements are written to the console . My question is : is there already an alternative more efficient implementation of LINQ to SortedSet SortedList out there .. . .. . i4o http : i4o.codeplex.com looks very interesting but it seems to require secondary index collections to improve query-performance on the original collection . I just want queries on my sorted collections to run faster by taking advantage of the sorting . Comment : The Where method in Linq to object check each element . So there is no performance gain using SortedList in this case . Comment : What query do you exactly want to do Because asserting LINQ is stupid is not really useful.. . Comment : The examples above are very typical for the kind of queries I want to run . I m sure there are more instances where LINQ to Objects could use the sorting but doesn t e.g . find min max so my question is if there s already a generic LINQ provider for sorted collections out there . Comment : Nice question I wonder how such a provider can be implemented . I ll investigate . Comment : This doesn t answer the question as stated but since you re using a SortedSet why not explicitly use the methods it provides instead of relying on LINQ to try to do the best thing E.g . for your first example int rangeCount mySortedSet1.GetViewBetween 1000000000 2000000000 .Count is always going to be faster no matter how optimised LINQ is . .. . Answer : The problem for LINQ is that it can t know the sorted set is ordered exactly the same way as the query expects . Since any ordered collection can be created with an IComparer IComparable Comparison T there is no knowing that 500000 actually makes sense . Maybe you ve got a custom method on the comparer that first sorts by Odd Even then by number . In which case the order would be completely messed up and O n is required in all cases . So to be on the safe side LINQ will need to iterate through all elements in the Collection even when it is sorted in some way . The default .Where implementation does not contain an optimization for ordered collections . It might be possible to create an optimized version which keeps the existing ordering in mind while iterating but it will be very difficult to do and to make it work in all cases . You could create a Between method that uses the GetViewBetween method of SortedSet to return a new pre-ordered collection . Or would add the standard .Where as you d normally would for any non-pre-sorted set . Linq-to-SQL and Entity Framework make use if the IQueryable and will actually translate your Linq query to SQL and let the server handle the indexing sorting filtering etc . Comment : Right I meant LINQ to Objects not LINQ to SQL . Comment : Even if the IComparer problem could be solved it would mean LINQ to objects would need Expression s not just Func delegates . Comment : It wouldn t as long as you d be able to detect which IComparer is being used . Which would at least solve the default sorting issues .

Answer : Create your storage account first with the settings that you want such as geo-replication disabled .

So far I have installed JamVm jvm jikes compiler and classpath libraries as per instructions in this tutorial http : wiki.gumstix.org index.php title Onboard Java Compiler . I have run a HelloWorld program and it seemed fine . Now when I try to run another application say MyApp that uses jpcap libraries the jvm gives me an error that looks like this : Exception during event dispatch : java.lang.UnsatisfiedLinkError : Native libarary jpcap not found as file libjpcap.so in gnu.classpath.boot.library.path and java.library.path . . . .. . .. .

Comment : Where on the target did you put the file libjpcap.so Comment : @ErikEkman I don t have that file . I thought that the jar file in the dist folder should have everything I need . So I guess I should find this file for my linux-distro angstrom and simply copy it over into my board . I guess it would go in usr lib Comment : @ErikEkman thanks Erik . I haven t actually managed to find the libjpcap.so file . I do have a jpcap tar ball but I am not sure if it s safe to copy it on Gumstix and then do a make install . All the documentation on Gumstix suggests either i using opkg or ii cross-compiling using openEmbedded . However that is a separate question and should be asked in a new thread . I have accepted your answer . many thanks .. . Answer : The libjpcap.so should be in gnu.classpath.boot.library.path or java.library.path as the error states . You can print these paths by getting them with System.getProperty java.library.path but usr lib is a good guess . Comment : thanks a lot for answering . I don t seem to find this file for my linux-distro . The rpms here http : rpmfind.net linux rpm2html search.php query libjpcap.so do not include anything for angstrom linux . The opkg utility on gumstix doesn t find jpcap either . Sorry this is off-topic Comment : It is not that important that it is for your distro as long as the architecture is the same . Run ldd libjpcap.so on target and if all dependencies are found you should be fine . Comment : I have now got libjpcap.so on my Gumstix I compiled jpcap natively using make . For some reason my java application still can t find it . I have tried putting this file at various locations 1.the folder containing the java app 2 . in usr lib 3 . in the folder containing jamvm classes but to no avail . I have a suspicion that I m not setting some library paths correctly . I am setting BOOTCLASSPATH usr share jamvm classes.zip : usr share classpath glibj.zip but I am not setting any other variable . Can someone help me with this problem Comment : did you compile it on your pc In that case you need to crosscompile for your target architecture . Run file libjpcap.so and make sure it does not say i386 or x86-64 but the mips arm whatever of your target . Comment : thank you Erik for staying with me . No I compiled it directly on my Gumstix board using the Makefile in jpcap src c . I am wondering if I need to have jre6 or jdk6 on my board . I currently have Jamvm on my board but not JRE . I thought they re the same but I now know they are not . When I type java -version the gumstix returns : java version 1.5.0 JamVM version 1.5.3 . .. . and some more stuff .", "Question : I am working on an embedded Linux device that has only qt .

We have a need to allow different developers to have different modifications to the responses because they are working on things relevant to different modifications . Initially when we installed this setup insider our LAN we were able to accommodate this by using the user id script parameter inside the GreasySpoon response scripts . This parameter is populated with the local IP of the developer and so we could base things upon the different IPs .

I configured authentication with the squid server but the user id is still set to our shared WAN IP . Is it possible to populate this script parameter in GreasySpoon with a proxy user s username using squid .. . Answer : The GreasySpoon 1.0.10 configuration file service.properties contains a setting : SpoonScript.icapuserheader x-authenticated-user . This is the header that GreasySpoon inspects to find the user id . If this value is not found then GreasySpoon falls back to the IP address .

Do i have to do something clever to write a spock test with Mocks for async code like GPARs - or is this something that should work but doesnt . I hope that clarifies my question for you Comment : I added two new tests to the spock test script . a simple wrapper for dynamicRule and one with ActiveObject GPARS support . test without active objects works fine . test with AOWrapper fails to execute correctly - dont know where to go now - is this a bug for gpars or cant i test async code like this with spock Comment : you should maybe try to extract a reproducible example a little smaller. . your question is very long to read and understand - Comment : Ok - i have cheated and dumbed this down so that it all the classes and the tests are in one groovy file - that way you can see the structure - and then the tests - see new addendum to question above to see this", "Question : I am using the plugin : Grails CSV Plugin in my application with Grails 2.5.3 . I need to implement the concurrency functionality with for example : GPars but I don t know how I can do it . Now the configuration is sequential processing . Example of my code fragment : .. . .. . Thanks . .. . Answer : Implementing concurrency in this case may not give you much of a benefit . It really depends on where the bottleneck is . For example if the bottleneck is in reading the CSV file then there would be little advantage because the file can only be read in sequential order . With that out of the way here s the simplest example I could come up with : .. . .. . As you can see the entire file is read first hence the main bottleneck . The majority of the processing is done concurrently with the map filter and sum methods . At the very end the transaction is rolled back if any of the Department s failed to save . Note : I chose to go with a map - sum pair instead of using anyParallel to avoid having to convert the parallel array produced by map to a regular Groovy collection perform the anyParallel which creates a parallel array and then converts it back to a Groovy collection . Improvements .. . .. . As I already mentioned in my example the CSV file is first read completely before the concurrent execution begins . It also attempts to save all of the Department instances even if one failed to save . You may want that which is what you demonstrated or not . Comment : Ok thanks . I have not copied all code only the main section . I will try it with this example . PD : When a row fails the execution is stopped doing a setRollbackOnly also . Comment : What is the difference between eachParallel collectParallel and anyParallel Comment : They are the concurrent equivalent of Groovy s each collect and any . Comment : OK allow me to elaborate . Let s take the methods collect collectParallel and map . Each of these methods does the same thing : it executes a closure for each item in a list and builds a new list from the return-value of the closure . The difference is that collect iterates through the list in sequential order . collectParallel breaks up the list and hands it off indirectly to threads and then joins the list back together so it looks like the output of collect . map is like collectParallel except it doesn t do the join step.. . Comment : For example map it 0 .trim is able to execute the closure and immediately pass the result down to the next step without having to wait to process the entire list . On the other hand collectParallel it 0 .trim must wait for the entire list to process before it can proceed to the next step .", "Question : Groovy : 1.8.6 .. . .. . GPars : 0.12 or 1.2.1 .. . .. . OS : Ubuntu 14.04 LTS .. . .. . When this code is executed NullPointerException is occurred often . Wider and wider the range of a and b is more and more easily this error is occurred . But the error is never occurred when the range is limited . I cannot understand why the error is occurred . Comment : Can you put the exception into your question Comment : Also can you use a version of groovy that s newer than 3 years old .. . Answer : From the code example you ve provided I m not 100 sure what you are trying to accomplish . It appears you are trying to an Actor for each value within the range provided and react to the message by printing out the value provided . Given that your code has some issues . The main issue is the lack of the loop closure which insures the Actor waits for the next incoming message after processing one . Secondly invoking stop doesn t help either . It simply stops the Actor from receiving additional messages . It doesn t hurt anything in your case since you immediately call join but adds to the confusion . To get this working here is your code simplified into a working example : .. . .. . In this example for each value in the range a message is added to the actor which reacts to the message by printing the value and then because of the loop closure waits for the next incoming message . So that example should accomplish what you want . However to give some clarity into what is going on in your code here is an explanation . When your Actor reacts to a message you are sending a message to a Reactor . Even though you don t explicitly return a value in Groovy the last line within a Closure is the return statement . As a result since your last line within the Closure is a println the return of that is null . So your Reactor returns null which is treated as a message to the Actor and again processed . To avoid this scenario you need to evaluate the return message and only delegate the message or print it if it has not yet been processed . I have updated your code intentionally return done as the return message for clarity . You could change the code to just check for a null message before processing it : .. . .. . import groovyx.gpars.actor.Actors", "Question : What is the status of this library at August 24 2015 The web page http : open-dolphin.org has some months without moves .

Doing so I wouldn t have to mention every import like import static groovyx.gpars.actor.Actors.actor separately like in this Hello World Example http : www.gpars.org 1.0.0 guide guide gettingStarted.html gettingStarted aHelloWorldExample . .. . Answer : It s really a style issue but at our company we ve decided that using in import statements is asking for trouble later on . Using you re importing quite a few things and you probably don t know what they all are . In this case it might not be an issue but using wildcard imports is pretty much guaranteed at some point to have you using a Utils class or some sort and having no idea which package you re getting that from . We even have a style violation for unused imports . Given today s IDEs with their very nice management of imports for you there s not much justification for being lazy about your import statements and potentially making problems for future developers on your codebase especially if it s you . Comment : I agree but with the one caveat . There are a limited number of places where a generic static import is appropriate or even the standard idiom junit test cases being the most obvious . Except in these limited cases I always list everything explicitly . If nothing else a huge list of imports is a hint that your class may be doing too much .", "Question : I think I got this wrong from the docs . I have two actors XMLActor and HttpActor . XMLActor reads xmlFiles and then sends a message to HTTPActor to process . XMLActor will finish way sooner than HttpActor . My main class calls join on both actors . I was expecting that the main thread would only terminate after both actors were done . But what is actually happening is that as soon as all messages are processed by XMLActor the system terminates and a lot of messages are not processed by HttpActor . I could use some latch or even an AtomicInteger to wait for all messages to be consumed but I was wondering if there s a more elegant way for it . .. . Answer : The join method will certainly wait for both actors to finish . I don t see how you stop the two actors so can t really comment on that . Do you send so sort of poison message Or call stop on actors For example the following simulation of your case stops correctly : Comment : You are right what was happening was an exception in HTTPActor that was silently killing the process . Took me a while to figure it out as the script was running in the background and sending output to dev-null : D Comment : One question is it mandatory to call stop I ran into another issue OOM errors I wonder if this was due the fact that I never stopped the actors and I was left with a few hundred thousand active actors in memory", "Question : I m trying to make a simple UDP socket server for a Unity3D game I m making and I ve got it mostly working .

Please note that an Oracle client or server installation is required in order to use cx Oracle . If you do not require the tools that come with a full client installation it is recommended to install the Instant Client which is far easier to install . EDIT link-to Instant Client : http : www.oracle.com technetwork database features instant-client index-097480.html Comment : Thanks for the reply which is really helpful . Another question stands out after that as I moved my script into another environment where an X64 version Oracle is installed the script failed . I did some research and found that might be due to the fact that the oracle client is 64bit and the python version is 32bit . Comment : The aforementioned issue solved by having a dummy 32bit Oracle client and set up the environment variable ORACLE HOME properly to the dummy client path . Comment : Yes the oracle client and the Python must match in bits for them to work together .

I m using python 2.6.1 on OS X 10.6.8 this is the system verison of python and am using the cx-Oracle driver module version 5.1 downloaded from sourceforge.net built and installed to a virtualenv 1.6.1 instance with site packages visible . My script is as follows .. . .. . I create a connection create the cursor execute a statment to create a test table with an id and text field of types NUMBER and NCLOB . I open a file containing what I know to be text encoded in UTF-8 decode the string to unicode . Create an insert statment in a unicode string and execute that statement and the result is this error . Something is trying to encode my statement as ASCII before inserting it into the Oracle schema . So I started hunting around looking to better understand how cx-Oracle handles unicode and found this in the HISTORY.txt of the cx-Oracle source I downloaded from sourceforge.net .. . .. . Changes from 5.0.4 to 5.1 .. . 1 Remove support for UNICODE mode and permit Unicode to be passed through in everywhere a string may be passed in . This means that strings will be passed through to Oracle using the value of the NLS LANG environment variable in Python 3.x as well . Doing this eliminated a bunch of problems that were discovered by using UNICODE mode and also removed an unnecessary restriction in Python 2.x that Unicode could not be used in connect strings or SQL statements for example . .. . .. . .. . My assumption is that the NLS LANG environment variable is set to ascii or some equivalent so I try setting NLS LANG to AL32UTF8 which I believe is the correct value for unicode and set the new value before creating my connection . But I get this error . So it looks like I cannot tamper with the NLS LANG value . Here are my questions as of now . Am I missing something simple like an incorrect column type Is the problem with the cx-Oracle driver Do I need to set the WITH UNICODE environment variable when building the cx-Oracle module and how would I do that Is the issue with the Oracle instance I have little experience with Oracle and have never worked with Oracle and python together . I ve spend two days working on this issue and would like a better understanding of what the issue is before I go to the DBA group with . Thanks .. . Answer : Setting environment variable is the right way but AL32UTF8 is not the right value for NLS LANG . To get the right value of the NLS LANG used in your instance of Oracle execute Comment : Thanks for the reply I finally received a response from my DBAs . For our 11gR2 installation the CHARACTER SET is WE8MSWIN1252 and the NATIONAL CHARACTER SET is AL16UTF16 . It appears that the driver is not detecting the encoding set in the above variables correctly . Checking the encoding and nencoding attributes on the connection yields US-ASCII in both cases which is incorrect . I still get the same DatabaseError when trying to NLS LANG to AL16UTF16 which since my connection to the schema is remove and will be in production also explains why those files cannot be accessed . Comment : In my situation my result from the above query being AMERICAN AMERICA.US7ASCII . However my Unicode inserts started working correctly once my NLS LANG was set to .AL32UTF8 without quotes . Comment : My result from the above query is AMERICAN AMERICA.WE8MSWIN1252 . @davidjb how do you set it to that value without quotes . What have you imported into your scope to get it Comment : I found this page http : www.oracle.com technetwork articles tuininga-cx-oracle-084866.html which had the code as os.environ NLS LANG .AL32UTF8 and that did the trick for me .

Answer : You ll find relevant information of how to access databases in Python by looking at PEP-249 : Python Database API Specification v2.0 http : www.python.org dev peps pep-0249 . cx Oracle conforms to this specification as do many database drivers for Python . In this specification a Connection object represents a database-connection but there is no built-in pooling . Tools such as SQLAlchemy http : www.sqlalchemy.org do provide pooling facilities and although SQLAlchemy is often billed as an ORM it does not have to be used as such and offers nice abstractions for use on top of SQL engines . If you do want to do object-relational-mapping then SQLAlchemy does the business and you can consider either its own declarative syntax or another layer such as Elixir http : elixir.ematia.de which sits on top of SQLAlchemy and provides increased ease of use for more common use cases .", "Question : How can I access Oracle from Python I have downloaded a cx Oracle msi installer but Python can t import the library .

Also which version of Python which version of Oracle and which operating-system are you using Comment : cx Oracle-5.0.2-10g.win32-py26 Comment : Sounds like it may not be extracted into the PATH python is using to look for modules . Have you tried installing it using easy install rather than explicitly it could be missing another dependency . .. . Answer : In addition to the Oracle instant client you may also need to install the Oracle ODAC components and put the path to them into your system path . cx Oracle seems to need access to the oci.dll file that is installed with them . Also check that you get the correct version 32bit or 64bit of them that matches your : python cx Oracle and instant client versions .", "Question : I am trying to run following code snippet in python to connect to oracle but constantly running into following error .

Comment : this actually disappeared after I added arguments required in cx-oracle constructor to create engine as kwargs which get passed to underlying cx-oracle call transparently . It was lacking those . .. . Answer : If you are running into this problem most likely the cause is that you are not passing in arguments required by the underlying dbapi call . In my case I added additional arguments of user password and dsn to the create engine call along with existing ones which got passed to cx-oracle call and it worked . something like this should work", "Question : I m trying to install the cx Oracle for Python 2.6 but it is failing .

Answer : You also need some type of Oracle client installed on your machine since cx Oracle is just a bridge between Python and the Oracle Client . Valid Oracle Clients include a full Oracle installation like Standard or XE or the Instant Client http : www.oracle.com technology tech oci instantclient index.html .. . .. . From the README http : cx-oracle.sourceforge.net README.txt : .. . .. . Please note that an Oracle client or server installation is required in order to use cx Oracle . If you do not require the tools that come with a full client installation it is recommended to install the Instant Client which is far easier to install . I have not installed on Windows before but you may have to set the ORACLE HOME environment variable so that cx Oracle knows where to look . Comment : I m trying to install the more substantial version but I already have basic installed there is no .msi or .exe . Comment : if you haven t installed on Windows have you installed on Ubuntu Debian I want to do that next . Comment : I looked at this guide and made some minor tweaks I am not using XE but Standard with Instant Client : catherinedevlin.blogspot.com 2008 06 http : catherinedevlin.blogspot.com 2008 06 cxoracle-and-oracle-xe-on-ubuntu.html", "Question : I m getting the standard DLL load failed module not found error when trying to import cx Oracle . I have the proper instant client installed the paths are all correct.. . running Dependency Walker tells me I m missing the following .dll s MSVCR90 GPSVC IESHIMS . I m running the instant client for Oracle 11g and Python 2.7 . Anyone have any ideas Most of the answers I have found entail an incorrect path but that doesn t seem to be the case.. . additionally I can t find any of those .dll s anywhere else on my system . EDIT : I ended up installing Oracle XE 11g 32-bit both Python 2.7 and the cx Oracle are also 32-bit I should also add that I m on Windows . cx Oracle now installs cleanly however upon connection I receive an error : .. . .. . The ORACLE HOME path is correct as is the bin in the PATH folder.. . .. . Answer : What version of Windows are you running Is it 32 or 64 bit Is your Oracle Instant Client 32 http : www.oracle.com technetwork topics winsoft-085727.html or 64 http : www.oracle.com technetwork topics winx64soft-089540.html bit Is your Python installation 32 http : www.python.org ftp python 2.7.3 python-2.7.3.msi or 64 http : www.python.org ftp python 2.7.3 python-2.7.3.amd64.msi bit Is your cx-oracle the correct version 32 http : prdownloads.sourceforge.net cx-oracle cx Oracle-5.1.2-11g.win32-py2.7.msi download or 64 http : prdownloads.sourceforge.net cx-oracle cx Oracle-5.1.2-11g.win-amd64-py2.7.msi download bit MSVCR90.dll is part of the Microsoft Visual C++ 2008 SP1 Redistributable package . 32-bit version available here http : www.microsoft.com en-us download details.aspx id 5582 64 bit version available here http : www.microsoft.com en-us download details.aspx id 2092 . IESHIMS.dll will be located in C : Program Files Internet Explorer Ieshims.dll 32-bit Windows location or 64 bit Windows Location or C : Program Files Internet Explorer x86 Ieshims.dll 32-bit Windows Location on 64 bit Windows if your version of Windows is Vista or newer . GPSVC.dll should live in C : Windows System32 . Dependency Walker reports these last 2 DLLs as missing because there are used by Windows Error Reporting which use IEFrame.DLL and are delay loaded which means they may never actually be needed . I found that in order to get cx-oracle to import cleanly you need to ensure that the versions of its dependencies match . You also need to ensure that the Oracle client installation matches your ORACLE HOME and your PATH variable contains ORACLE HOME bin which is set as an Environment variable or in the registry and that your tnsnames.ora file lives in the value TNS ADMIN is set to . As stated in Emmanuel s answer the default-value for an unset TNS ADMIN setting is ORACLE HOME network admin . I also rarely used the instant client version of the oracle installer unless absolutely necessary because unlike the other versions it doesn t set always ensure are set or maintained Path ORACLE HOME or TNS ADMIN correctly which lead to tnsnames.ora and OCI.dll not being found . This gets more complicated when you have multiple Python versions or Oracle versions on the same machine . To explicit set them you can use Environment Variables either User or System which live in the Control Panel under the System Icon Advanced system settings task Advanced Tab Environment button . Regarding InterfaceError : Unable to acquire Oracle environment handle this occurs specifically when opposed to not resolving OCI.dll cx Oracle doesn t know which OCI.dll to use normally this is the case because of the PATH variable containing two or more search directories that contain OCI.dll . Specifically ensuring your PATH only contains one instant of OCI.dll either from the instant client installation or the Oracle 11G XE instllation should fix your problem . Did you uninstall the instant client before installing Oracle 11G XE Paste the following in a Command Prompt . echo The current ORACLE HOME is ORACLE HOME .. . .. . echo The current TNS ADMIN is TNS ADMIN .. . .. . echo The current PATH is PATH .. . .. .

Comment : Can I use jquery.uls on a MediaWiki wiki to get a language code from the name of a language in English http : stackoverflow.com questions 29485489 .. . Answer : You can t do this directly because JS runs on the client and Lua on the server . What you can do is to use the MediaWiki API from JS https : doc.wikimedia.org mediawiki-core master js api mw.Api to invoke the module . Specifically using the expandtemplates API module http : en.wikipedia.org w api.php action help modules expandtemplates . For example if you wanted to call the function h2d from Module : Hex https : en.wikipedia.org wiki Module : Hex with the parameter FF invoke : hex h2d FF in wikitext and alert the result then the JS would look like this : .. . .. . .. . .. . And for the OP s specific case running on the English Wiktionary : .. . .. . prop : wikitext avoids a warning from the API and lets you access the result as data.expandtemplates.wikitext rather than the slightly mystifying data.expandtemplates .

I can t imagine any use-case for checking query-string . Could you describe from user s point of view what would you like to achieve Possibly you took wrong approach . Comment : I want to allow users to submit forms via GET method for which I think I need to build an extension as the current form extensions did not appear to fit the bill so that they can specify a subset range of paragraphs to display using the Labeled Section Transclusion section and then share bookmark the result . I like the idea of keeping resolution logic accessible from templates . Comment : The Semantic Forms extension appears to support a similar approach but only for POST requests and it seems a bit heftier than what I need . .. . Answer : If this is an option consider obtaining HTML content with API http : www.mediawiki.org wiki API 3aParsing wikitext . This should be simpler than writing an extension . Of course this won t be a regular page rather something composed client-side on blank article or server-side on non-wiki site . With Labeled Section Transclusion http : www.mediawiki.org wiki Extension 3aLabeled Section Transclusion extension you mentioned this should work . Alternatively consider some server-side post processing on generated HTML . It should perform quite well as MediaWiki caches a lot . AFAIK there is no magic word for checking query-string and IMO this would be a very bad thing . Article source is like a model in MVC pattern you shouldn t put presentation stuff there . Comment : I still think it would be quite convenient to have a way that people could simply add iframes to grab portions of a wiki text without additional server-side code e.g . for excerpting literature from Wikisource . Also I think you mean shouldn t put controller stuff there no I really think the already dynamic nature of templates ought to be usable from outside the site via REST . Comment : It s a pity the action render from mediawiki.org wiki Manual : Parameters to index.php Actions http : www.mediawiki.org wiki Manual : Parameters to index.php Actions doesn t work with a text argument instead of title as in the API --it shouldn t be any XSS risk as it would still be parsed .

Finally I tried adding the table creation tags into the invoking template using and and modifying the lua module to t mw.create.html but while the row template tags was fine the tags in the lua module were translated . How do I prevent MediaWiki from translating these tags into html-entities Comment : Have you tried feeding it HTML entities 123 124 125 This worked well for me when using templates inside templates . And sometimes MW is just weird : .. . Answer : In addition to what Kasper said : AFAIK your module should output wikitext not HTML . Also nested template invocation makes teh whole thing quite fragile probably compensating any gain produced by using Lua . This invocation with explicit parameter would already be less fragile : .. . .. . Better yet usually people avoid nesting the templates at all and just do : .. . .. . Alternatively if using Lua you should make a template which passes an unlimited number of parameters to a module which produces wikitext for the entire table header included .

Answer : Look very very carefully at your pastebinned code compared to Wikipedia s code . In fact I d recommend performing a diff of the two . Your code http : pastebin.com RyTeRGk5 .. . .. . Wikipedia https : en.wikipedia.org wiki Module 3aHtmlBuilder .. . .. . .. . .. . Do you see the difference Metamethods in Lua http : www.lua.org pil 13.html always start with two underscores not one . I m not sure how your code got to the state that it s in but this would very well explain all the troubles you ve been having even why attr was not accessible . It was due to the metatable s index http : www.lua.org pil 13.4.1.html field lacking an underscore which of course means that it would not be recognized at all . I m surprised I noticed since it s easy to miss that extra underscore when skimming . I would recommend restoring your HtmlBuilder module to its original state first then see if that fixes your issue . You might want to restore NavBox and any others you may have modified if your modifications aren t too significant but a diff https : en.wikipedia.org wiki Diff would definitely tell you what s different between your versions .

The server sends a n character as delimiter between consecutive responses . Below given is a model implementation. . .. . .. . Well I hope the structure is clear now . This response is transmitted from server zlib compressed . So I have to first inflate whatever I am reading from the server separate on response using delimiter and parse . And I am using SAX to parse my XML .. . .. . Now my main problem is the xml response coming from server can be very large can be in the range of 3 to 4 MB . So .. . .. . to separate responses based on delimiter n I have to use a stringBuilder to store response blocks as it reads from socket and on some phones StringBuilder cannot store strings in the MegaBytes range . It is giving OutOfMemory exception and from threads like this http : stackoverflow.com questions 4729188 android-convert-stream-to-string-without-running-out-of-memory I got to know keeping large strings even on a temporary basis is not such a good idea . Next I tried to pass the inflatorReadStream which in turn takes data from socket input stream as the input stream of SAX parser without bothering to separate xml myself and relying on SAX s ability to find the end of document based on tags . This time one response gets parsed successfully but then on finding the n delimiter SAX throws ExpatParserParseException saying junk after document element . After catching that ExpatParserParseException I tried to read again but after throwing exception SAX Parser closes the stream so when I try to read parse again it is giving IOException saying input stream is closed . A code snippet of what I have done is given below removed all unrelated try-catch blocks for clarity . And now my questions are .. . .. . 1 . Is there any way to make SAX Parser ignore junk characters after on xml response and not throw exception and close the stream. . .. . 2 . If not is there any way to avoid out-of-memory error on stringBuilder . To be frank I am not excepting a positive answer on this . Any workaround .. . Answer : If your SAX parser supports a push model where you push raw data chunks into it yourself and it fires events as it parses the raw data then you can simply push your own initial XML tag at the beginning of the SAX session . That will become the top-level document tag then you can push the responses as you receive them and they will be second-level tags as far as SAX is concerned . That way you can push multiple responses in the same SAX session and then in the OnTagOpen event or wheatever you are using you will know when a new response begins when you detect its tag name at level 1 . Comment : Well @Remy thanks for the reply you will know when a new response begins when you detect its tag name at level 1 In my case second response is not getting started after SAX completely parsed first response it throws an exception on second response because of the delimiter n in between two responses. . And also it close the stream. . Comment : That would only be true if you are parsing the responses as top-level documents . XML only supports 1 tag at level 0 . You cannot have multiple top-level tags . Hense my suggestion to push the responses to level 1 by wrapping them in a custom tag at level 0 . I use this technique when pushing streaming XML from TCP through a SAX parser and it works very well . Comment : You are still not getting it . A push-based SAX parser does not care about those issues at all It is designed to work with arbitrary chunks of any size and any portion of the total data . As arbitrary chunks are pushed into the parser the parser buffers what it needs internally and then fires events whenever finished tags exist in the buffer . You will receive events for each individual response datas and data tag that is pushed into the parser regardless of how many chunks it took to receive them from the stream.. . Comment : .. . and you don t have to worry about the line break at all because it falls between tags and is thus just whitespace that can be discarded . Comment : If there are multiple doctypes then you will have to strip them off manually before then pushing the rest of the data into the parser but only if the charset is always the same or if the parser allows you to change its active charset dynamically . Otherwise you would have to do your own buffering and only parse individual documents again with using a push parser at all .", "Question : I am writing a Java program to read and XML file actually an iTunes library which is XML plist format .

The XLM file represents this ampersand as 38 and I can only manage to read the text following the 38 in any particular section of text . Is there a way to disable detection of escape codes I am using SAXParser . .. . Answer : There is something fishy about what you are trying to do . If the file-format you are trying to parse contains bare ampersand characters then it is not well-formed XML . Ampersands are represented as character entities e.g . amp in well-formed XML .

You might want to use a different more robust parser . SAX is great as long as the file is well-formed . I do however not know how robust dom4j and jdom are . Just give them a try . For python I know that I would recomment ElementTree or BeautifulSoup which are very robust . Also have a look at http : code.google.com p xmlwise which I found mentioned here in stackoverflow did you use search . Update : as per updated question You need to understand the role of entities in XML and thus SAX . They by default a separate nodes just like text nodes . So you will likely need to join them with adjacent text nodes to get the full value . Do you use a DTD in your parser Using a proper DTD - with entity definitions - can help parsing a lot as it can contain mappings from entities such as amp to the characters they represent and the parser may be able to do the merging for you . At least the python XML-pull parser I like to use for large-files does when materializing subtrees .", "Question : I am developing an application in which the first time I am going to parse data from an xml file coming from a remote-server .

The Nodes are in the form of Tree Structure . Memory : It Occupies more memory DOM is only preffered in the case of small XML documents . Slower at runtime . Stored as an objects . Programmatically easy to implement . Ease of navigation and use . SAX : .. . .. . Sequence of events . It doesn t use any memory preferred for large documents . Faster at runtime because of the above mentioned point . Objects are to be created . Need to write code for creating objects . In SAX Backward navigation is not possible as it sequentially processes the document . Comment : +1 . This is an excellent comparison . I would emphasize that SAX is more difficult to implement because you the programmer must step through the nodes . But it is faster uses less memory and is far better suited to large XML data sets or streaming XML data .

The server sends a n character as delimiter between consecutive responses . Below given is a model implementation. . .. . .. . Well I hope the structure is clear now . This response is transmitted from server zlib compressed . So I have to first inflate whatever I am reading from the server separate on response using delimiter and parse . And I am using SAX to parse my XML .. . .. . Now my main problem is the xml response coming from server can be very large can be in the range of 3 to 4 MB . So .. . .. . to separate responses based on delimiter n I have to use a stringBuilder to store response blocks as it reads from socket and on some phones StringBuilder cannot store strings in the MegaBytes range . It is giving OutOfMemory exception and from threads like this http : stackoverflow.com questions 4729188 android-convert-stream-to-string-without-running-out-of-memory I got to know keeping large strings even on a temporary basis is not such a good idea . Next I tried to pass the inflatorReadStream which in turn takes data from socket input stream as the input stream of SAX parser without bothering to separate xml myself and relying on SAX s ability to find the end of document based on tags . This time one response gets parsed successfully but then on finding the n delimiter SAX throws ExpatParserParseException saying junk after document element . After catching that ExpatParserParseException I tried to read again but after throwing exception SAX Parser closes the stream so when I try to read parse again it is giving IOException saying input stream is closed .

You might be able to use a wrapper around the reader or stream you pass to the filter that detects the newline and then closes the parser and launches a new parser that continues with the stream : your stream is NOT valid XML and you won t be able to parse it as you currently have implemented .

Answer : Did you check the GPU utilization You could try nVidia nSight Tegra https : developer.nvidia.com nvidia-nsight-tegra . The high CPU utilization is per core or per processor If per processor this might indicate that RS has parallelized the task among cores . Are you using Tegra Android Development Pack https : developer.nvidia.com tegra-android-development-pack It may be that nVidia supports RenderScript just for the CPU side . Since K1 has a CUDA based GPU the logic for putting any type of code on the GPU may not be implemented .

Answer : How do you get the maximal number of float operations in flops from a GPU For instance on a GK20A GPU embedded in Tegra K1 which can go up to 852 Mhz and has 192 cuda cores each of them can do only one basic fp operation per cycle - if I read the specs http : docs.nvidia.com cuda cuda-c-programming-guide index.html arithmetic-instructions throughput-native-arithmetic-instructions correctly and can go up to 852 Mhz my first guess was basically : 852 192 163 GFLOPS .

Can the code used for current supercomputers be easily converted to code that will run well on these Mobile chips Thanks . Comment : The ARM host might be RISC but I m not sure if you can call the NVIDIA K1 either RISC or CISC . .. . Answer : Can the code used for current supercomputers be easily converted to code that will run well on these Mobile chips It depends what you call supercomputers code . Usually supercomputers run high-level functional code usually fully compiled code like C++ sometimes VMs-dependent code like Java on top of other low-lewel code and technologies such as OpenCL or CUDA for accelerators or MPICH for communication between nodes . All these technologies have ARM implementations so the real thing is to make the functional code is ARM-compatible . This is usually straightforward as code written in high level language is mostly hardware-independent . So the short answer is : yes . However what may be more complicated is to scale this code to these new processors . Tegra K1 is nothing like the GPUs embedded in supercomputers . It has far less memory runs slightly slower and has only 192 cores . Its price and power consumption make it possible however to build supercomputers with hundreds of them inside . So code which have been written for traditionnal supercomputers a few high-performance GPUs enbedded will not reach the peak performance of new supercomputers built with a lot of cheap and weak GPUs . There will be a price to pay to existing code on these new architectures .", "Question : I wonder what new OpenGL ES extensions are on the new Tegra 3 devices Anyone care to post their device name OpenGL version and a list of extensions Tegra 3 devices only please I think other developers could use that too .

I m totally new in Nvidia Tegra world . I have installed latest Visual Studio 2015 Professional trial and CodeWorksforAndroid-1R3-windows . When I m trying to create new project Android Application Nsight Tegra - I m getting this error : .. . .. . enter image description here http : i.stack.imgur.com 174RM.png .. . .. . It reminds mi some Visual Studio addon errors I had before but I have no idea what to do . Guys can you help me with that .. . Answer : That s due to the fact that Visual C++ component is not installed on your machine - please run the VS IDE installer switch to the Custom setup and install the Visual C++ . Nsight Tegra VS Edition does require the Visual C++ VS IDE component to be installed on the developer s machine . See the msdev http : msdev.developer-works.com article 29437711 Upgrading+from+Visual+Studio+2015+RC+to+Visual+Studio+2015+failed for the details .", "Question : How many resident warps are present per SM in GK20a GPU tegra k1 As per documents I got following information In tegra k1 there is 1 SMX and 192 cores multiprocessor .. . .. . Maximum number of threads per multiprocessor : 2048 Maximum number of threads per block : 1024 Can any one specify value of maximun blocks per SMX Is 32 4 128 no of threads in warp no of warp AS kepler allowing four warps to be issued and executed concurrently threads running concurrently if NO How many number of threads run concurrently Kindly help me to solve and understand it . .. . Answer : Each block deployed for execution to SM requires certain resources either registers or shared-memory . Let s imagine following situation : .. . .. . each thread from certain kernel is using 64 32b registers 256B register memory .. . kernel is launched with blocks of size 1024 threads .. . obviously such block would consume 256 1024B of registers on particular SM .. . .. . I don t know about tegra but in case of card which I am using now GK110 chip every SM has 65536 of 32-bit registers 256kB available therefore in following scenario all of the registers would got used by single block deployed to this SM so limit of blocks per SM would be 1 in this case.. . Example with shared-memory works the same way in kernel launch parameters you can define amount of shared-memory used by each block launched so if you would set it to 32kB then two blocks could be deployed to SM in case of 64kB shared-memory size . Worth mentioning is that as of now I believe only blocks from same kernel can be deployed to one SM at the same time . I am not sure at the moment whether there is some other blocking factor than registers or shared-memory but obviously if blocking factor for registers is 1 and for shared-memory is 2 then the lower number is the limit for number of blocks per SM . As for your second question how much threads can run concurrently the answer is - as many as there are cores in one SM so in case of SMX and Kepler architecture it is 192 . Number of concurrent warps is obviously 192 32 . If you are interested in this stuff I advise you to use nsight profiling tool where you can inspect all kernel launches and their blocking factors and many more useful info . EDIT : Reading Robert Crovella s answer I realized there really are these limits for blocks per SM and threads per SM but I was never able to reach them as my kernels typically were using too much registers or shared-memory . Again these values can be investigated using Nsight which displays all the useful info about available CUDA devices but such info can be found for example in case of GK110 chip even on NVIDIA pages in related document http : www.nvidia.com content PDF kepler NVIDIA-Kepler-GK110-Architecture-Whitepaper.pdf . Comment : The CUDA core count is the number of single precision integer thread operations that can be issued per cycle . NVIDIA GPUs also have special function units double precision units load store units branch units etc . that can be issued to so the core count should only be discussed with respect to a subset of the instructions . See the Fermi Kepler and Maxwell architecture whitepapers for additional details . Comment : Copied over from GK110 whitepaper : SMX : 192 singleprecision CUDA cores 64 doubleprecision units 32 special funct ion units SFU and 32 load store units LD ST -- therefore I believe that core is core and special instruction unit is something else which simply regular SP core utilizes during its computation . Or are my assumptions incorrect Comment : A CUDA core is a math ALU pipeline . It is not a core . On each cycle a CC3.0-5.0 warp scheduler picks a warp and can issue instructions two pipelines where the pipelines are int sp CUDA core double precision unit special function unit load store unit branch unit .. .", "Question : I want to find the hardware codec codec of tegra 3 in android-source code 4.1 .

Does anyone can help point out where to find the tegra 3 hardware codec code Comment : It s almost certainly shipped as a blob - a binary only library . Unless you have an NDA with nVidia that is . Comment : @Marko thanks for your comment . Sorry that I didn t describe my question well . I just want to know where is the makefile that builds the libstagefrighthw.so . For example for omap3 platform the Android.mk is located in androidOS Android4.1 hardware ti omap3 libstagefrighthw . Comment : Well I wrote an example according to Acodec.cpp in androidOS Android4.1 frameworks av media libstraight . It can work but the decoding has a high latency about 2 4 seconds for 640x480 resolution . .. . Answer : The libstagefrighthw library is simply glue code that patches vendor proprietary media framework with libstagefright framework within Android . This approach is used to implement hardware specific custom codecs https : source.android.com devices media.html . The qcom ti code you see is the one that got sync-ed into the mainline Android repository quite sometime back . For tegra-specific code you will need to get your hands on a proper Tegra development repository . This http : nv-tegra.nvidia.com gitweb maybe .. . .. . You may also want to checkout the Tegra3 libstagefrighthw https : github.com CyanogenMod android device htc tegra3-common tree cm-10.2 libstagefrighthw code within the CM 10.2 repo .", "Question : To clarify can this RISC base processor the Tegra K1 be used without significant changes to today s supercomputer programs and perhaps be a game changer because if it s power size cost and energy usage I know it s going up against some x64 or x86 processors . Can the code used for current supercomputers be easily converted to code that will run well on these Mobile chips Thanks . Comment : The ARM host might be RISC but I m not sure if you can call the NVIDIA K1 either RISC or CISC . .. . Answer : The question is should it Intel keeps proving that ARM is inferior and the only factor speaking for using RISC base processors is their price which I highly doubt is a concern when building super computer . Comment : Your response is fraught with invalid assumptions . You don t appear to have a good grasp of the RISC vs . CISC debate . And price is absolutely a concern when building a supercomputer . The only part you got right is that Intel makes superior processors to ARM ." ] }

I know I can create a .sh file but I don t want to do that is there any way to chain commands in go so the mongo db doesn t close and I can execute the other commands .. . Answer : You seem to misunderstand how processes such as interpreters and shells including it appears https : jira.mongodb.org browse SERVER-10569 mongodb as well work with their so-called standard streams https : en.wikipedia.org wiki Standard streams : while the test-db is indeed an argument to pass to a mongodb process to be created on its command-line the db.user.remove id : 1 is the text that spawned mongodb instance is supposed to read from its standard input stream . So basically you need this : .. . .. . To explain how this works let s cite the manual https : golang.org pkg os exec Cmd : .. . .. . Stdin specifies the process s standard input . If Stdin is nil the process reads from the null device os.DevNull . If Stdin is an os.File the process s standard input is connected directly to that file . Otherwise during the execution of the command a separate goroutine reads from Stdin and delivers that data to the command over a pipe . In this case Wait does not complete until the goroutine stops copying either because it has reached the end of Stdin EOF or a read error or because writing to the pipe returned an error . Stdin io.Reader .. . .. . So basically you create an object which takes a string and provides something implementing io.Reader and wire it to the standard input of the process about to be created . Once the process starts os exec will make sure to spawn a goroutine which will shovel data between your string and the running mongodb instance as-if you would start mongodb by hand and typed that string onto its standard input stream directly . Note that you also might need to check what mongodb generates on its standard output streams especially stderr because if it encounters any errors while executing the script you have submitted to it it will likely report them there .", "Question : I m trying to connect to a MongoDB database that requires a password while also loading and running a script file on the database .

This time with show dbs I was rewarded with admin local and meteor . I use meteor and then show tables and there they are my missing tables . Weird . Guess I m still looking for an answer . .. . Answer : If you want to use the regular mongo console you have to specify the port to be 3001 for meteor apps instead of the default 27017 . Otherwise it s much simpler to just type meteor mongo and connect that way . Then you can type show collections and it will show them all just like normal ." ] }

I tested this with gcc 4.7.2 and clang 3.2 . It should contain everything you need to use anything in the mpl actually a litte more than it needs . You can think of a tuple as a mpl : : list forward iterator compile type . So to make it play nice you should implmenet what boost : : mpl : : list does . A quick look into the boost-mpl list aux directory : begin end.hpp empty.hpp iterator.hpp pop front.hpp push back.hpp size.hpp clear.hpp front.hpp push front.hpp tag.hpp are the relevant files that need to be implemented .", "Question : The Tutorial : Metafunctions and Higher-Order Metaprogramming http : www.boost.org doc libs 1 56 0 libs mpl doc tutorial implementing-division.html section of the Boost MPL library documentation states that transform can be invoked like so .. . .. . where the placeholders 1 and 2 signify that when the transform s BinaryOperation is invoked its first and second arguments will be passed on to minus in the positions indicated by 1 and 2 respectively . I ve been reading this over and over again for almost a month and I still don t understand it . What values exactly do the placeholders 1 and 2 have D1 and D2 If so why not write mpl : : minus D1 D2 Also considering that the placeholders are defined as http : www.boost.org doc libs 1 56 0 libs mpl doc tutorial placeholders.html typedef arg 1 1 and typedef arg 2 2 and consequently the original expression in my mind amounts to .. . .. . I m sure I m thinking about placeholders the wrong way . I d appreciate some guidance here . .. . Answer : Indeed you re thinking about placeholders the wrong way . mpl : : minus is a template in MPL s metalanguage that symbolically represents or corresponds to a certain high-level behavior namely subtraction . You re thinking of it as-if it s a non-meta construct such as a function .. . .. . but it s not . The standard C++11 library does have something kind of like that called std : : minus http : en.cppreference.com w cpp utility functional minus void but that s not what mpl : : minus does mpl : : minus represents the subtraction operation at a higher level of abstraction . Don t worry for another couple of paragraphs about how mpl : : minus is implemented . Just think about what it represents which is subtraction of two things . Ah but which two things Well mpl : : minus lets you specify those things as template parameters . For example .. . .. . expands to a type whose member typedef type is the same as mpl : : int 4 . Okay but in the dimensional analysis example from Boost they don t have just two things they have sequences D1 and D2 of dimensions . This is a very important point Subtracting sequences isn t the same thing as subtracting integers consider .. . .. . Likewise in the meta space .. . .. . What we mean to say in the first case is .. . .. . and what we mean to say in the second meta case is .. . .. . Notice that the C++11 std : : transform takes pairs of iterators a.begin a.end instead of just a it takes b.begin but not b.end a deficiency that is only now being corrected by the Committee https : www.youtube.com watch v dTeKf5Oek2c and it mutates c via an output iterator rather than returning a completely new object for efficiency . MPL s compile-time meta-version takes containers a and b directly and returns a new container c i.e . it has value semantics which IMHO is strictly easier to think about . So the above is all correct EXCEPT for one tiny detail mpl : : transform is actually a very generic algorithm which means that it expects you to spell out the details of the transformation . You said mpl : : minus which means subtract okay but subtract what from what Subtract the elements of the first sequence from elements of the second Subtract the second s elements from the first Subtract 42 from the elements of the second sequence and toss out the first one entirely Well we mean subtract the second sequence s elements element-wise from the first s . Which we write as .. . .. . We could equally well write .. . .. . it would mean the exact same thing . This generic transform algorithm lets us write complicated transforms such as .. . .. . Here we can refer to the same element of sequence a three times using the symbol 1 while 2 refers to the corresponding element of sequence b . So that s the point of the symbols 1 and 2 in the context of mpl : : transform . But you re probably still wondering how they re implemented . Well there s no magic here . They might as well be implemented as .. . .. . As long as they get unique distinguishable entities in C++ s type system that s all MPL really cares about . But in fact they re actually implemented as typedefs for specializations of mpl : : arg http : www.boost.org doc libs 1 48 0 libs mpl doc refmanual arg.html which leads to a nifty trick . Since 1 is a synonym for mpl : : arg 1 we can say .. . .. . and I would guess that mpl : : transform is able to take advantage of that fact internally . Comment : Journey into madness and back .

Answer : The MPL is ill-suited for mixed compile-time run-time operations . The only operation allowed at runtime on MPL sequences is for each . For all other situations you should roll your own . So you should effectively consider that MPL types are not meant to be instanciated . However there are other facilities in Boost for such a thing . The old : Boost.Tuple .. . .. . The new : Boost.Fusion http : spirit.sourceforge.net dl more fusion v2 libs fusion doc html index.html http : spirit.sourceforge.net dl 5Fmore fusion 5Fv2 libs fusion doc html index.html .. . .. . Boost.Fusion is a bit more complex it integrates the concept of views for example but would be far better suited to your example . It does not mean that you should not use the MPL . On the contrary it is explicitly stated in the Boost.Fusion reference document that one should use MPL algorithms for compile-time computations and then build the Boost.Fusion container only at the moment you cross the compile-time runtime boundary even though Boost.Fusion container are supposed to work with MPL algorithms .

This probably does not help you unless you already know the MPL well enough that you don t ask questions on SO about it - so basically it means that it returns a new type that s like a boost : : mpl : : vector except for its actual type which may be anything like I showed above .

The following will work : Comment : Thanks a lot for your answer . :", "Question : Since you can take integral values as template parameters and perform arithmetic on them what s the motivation behind boost : : mpl : : int and other integral constants Does this motivation still apply in C++11 Comment : If this is really of interest to you read the book C++ Template Metaprogramming by the main authors of Boost MPL it explains the motivations behind all these kinds of things . And this is not only valid for C++11 it has been made standard in C++11 with std : : integral constant http : en.cppreference.com w cpp types integral constant . .. . Answer : You can take integral values as template parameters but you cannot take both types and non-type template parameters with a single template . Long story short treating non-type template parameters as types allows for them to be used with a myriad of things within MPL . For instance consider a metafunction find that works with types and looks for an equal type within a sequence . If you wished to use it with non-type template parameters you would need to reimplement new algorithms overloads a find c for which you have to manually specify the type of the integral value . Now imagine you want it to work with mixed integral types as the rest of the language does or that you want to mix types and non-types you get an explosion of overloads that also happen to be harder to use as you have to specify the type of each non-type parameter everywhere . This motivation does still apply in C++11 . This motivation will still apply to C++y and any other version unless we have some new rule that allows conversion from non-type template parameters to type template parameters . For instance whenever you use 5 and the template requests a type instantiate it with std : : integral constant int 5 instead .

Becaues I have far more than in the example and I am afraid at the end of the project there will be even more . Comment : I think I am missing something here as numerous users have corrected me after I fixed the title to say cartesian-product http : en.wikipedia.org wiki Cartesian product instead of permutation . I am happy to risk embarrassment for getting an aha experience . Why everyone insists this is about permutation .. . Answer : Ok here is some implementation . It is rather ad-hoc one could obviously abstract it to take a sequence of sequence of lambda function but I preferred keeping this one straight . Comments and tests are inside : .. . .. . The expected output should be : Comment : Unbelievable . This is exactly what I want . I guess I need to work on my template skills . Comment : I have one last question left . What exactly does the boost : : mpl : : apply FuserFunc T do I tried to use some other apply function but I cannot figure out how mpl : : apply works . Comment : apply takes a metafunction and a type and call the metafunction over T . It s basically a generic way to apply metafunctions over a set of templates arguments .

Btw I can t use constexp or new standard in general - I have C++03 compiler . Thanks .. . .. . UPD : Sorry for my mismatch - I mean not multibyte character but multicharacter literal regarding standard - 2.14.3 n3797 . Somrthing like this http : stackoverflow.com questions 3960954 c-multicharacter-literal Comment : Why are you using multicharacter literals You realize printing out a multicharacter literal like MY CONST1 is not in general going to produce MY CONST1 as output .

Somrthing like this That s a completely different thing vs . multibyte character you are completely seem to be confused about this . Multicharacter literals are implementation defined and dependent don t use them . It s not portable by means of standards . What else did you miss from that link you gave Comment : @ I already told that that was my mistake . I just want to work with boost : : mpl : : string . The only way to do this is to use multicharacter literal . The link that I gave is just to show what is multicharacter literal .

Then some other code calculates the sum of these numbers up to the type defined by key e.g . for Definition : : D the sum is 5 + 3 + 6 A + B + C . This needs to be done at compile-time . That s why I use mpl : : vector and some appropriate meta-programming . I don t like the current approach since it somehow violates the DRY rule . I m wondering whether it would be possible to provide such struct definition without the need to repeat type names in the mpl : : vector for Seq type . In other words I d probably need a bunch of macros which would allow me to write code like this : .. . .. . And then Definition : : A would still refer to boost : : mpl : : int 5 or would at least allow me to access the boost : : mpl : : int 5 somehow and Definition : : Seq would give me the appropriate MPL sequence . Of couse this is just my imagination . The code might look different I m just looking for options . .. .

Does anyone have any details on the state of the C++ conformance of the sun 5.10 compilers I could always compile using GCC . Comment : Boost : : MPL seems to have an extensive set of unit tests you can try to run them under your compiler .

Here is what I tried . Following instructions http : www.joecjr.com 2014 07 27 install-and-use-freetds-unixodbc-and-rodbc-or-pyodbc I already setup unixODBC FreeTDS using Homebrew and all the tsql isql connection tests were fine .

And choose ODBC from Connect to an existing database I entered s01 my unixODBC DSN name to Name of the ODBC data source on your system field . When I clicked Browse no registered data source were shown . And I typed my unixODBC username and checked Password required . When I clicked Test Connection button and input the password an error occurred as below . Does anyone have an idea to solve this problem .. . Answer : I would recommend you stick with iODBC the ODBC driver manager Apple has shipped as part of OS X since Jaguar 10.2 . The version Apple bundles into Yosemite 10.10 remains a bit behind at 3.52.6 so I would also recommend you update to 3.52.10 http : www.iodbc.org dataspace iodbc wiki iODBC Downloads Mac OS X . iODBC and UnixODBC are built to be API equivalent so you should just need to ensure that your drivers and DSNs are properly configured in the iODBC locations optimally via iODBC Administrator.app Applications iODBC .

I also had this problems . Reinstalling", "Question : After 2 days battling I try asking help here . I m using unixODBC 2.2.11 to work with DB2 iSeries and PHP 5.3 on a CentOS 5.4 server . I guess it s since the upgrade of PHP from 5.1 to 5.3 I get PHP to segfault on certain queries . After some investigation I discovered the problem appears on some queries with long char fields for example with this table : .. . .. . This simple piece of code provokes the segfault : .. . .. . Is there any column length limit or a bug with unixODBC and or PHP 5.1 This web application worked quite great then I got into this problem. . .. . .. . Btw I tested with a more up-to-date 64bits CentOS 6.2 machine with unixODBC 2.2.14 and PHP 5.3 and the problem is the same . Any help greatly appreciated .. . .. . Thanks .. . .. . fabien .. . .. . UPDATE : Using the PHP odbc functions it works : .. . .. . So the problem is more tied to PDO any idea .. . Answer : I cannot say I know of any issues in pdo which I don t use anyway or unixODBC or the DB2 driver . I m not sure from your email if your first platform is using 64 bit builds or 32-bit builds but ODBC changed when Microsoft added 64 bit support see SQLLEN SQLULEN and 32 64 bit platforms http : www.martin-evans.me.uk node 20 and 64-bit ODBC http : www.easysoft.com developer interfaces odbc 64-bit.html . Basically some ODBC APIs had a type changed from SQLINTEGER to SQLLEN and an SQLLEN is 64bits in a 64 bit build and 32 bits in a 32-bit build . However as no one was to know Microsoft was going to do this and some of these arguments were actually described in the spec as 32-bit quantities some ODBC driver writers had already built ODBC drivers for 64 bit platforms using 32-bit quantities for these arguments . Obviously if you mix an application or driver manager built one way with a driver built the other way all hell can break lose and you very well may get segfaults . So firstly if you are using 64 bit binaries you need to check your ODBC driver was built correctly - speak to IBM . unixODBC 2.2.11 is rather old now and I know issues have been fixed but I m still using it extensively and only have one small issue in the cursor library . Anyway you tried 2.2.14 and the problem was the same . I doubt it is an unixODBC issue but that is only based on my extensive experience with it and not because I know for a fact . Now assuming you don t fall into the situation outlined above you can do a number of things . Try enabling logging in unixODBC then you can see what ODBC calls are being made and which one fails . You might also get a clue from the arguments passed as to what might be going on . You enable logging by adding the following to your odbcinst.ini file : .. . .. . Look for a call to SQLBindCol or SQLGetData for the column in question . If this does not get you anywhere you can try pasting the end of it here and I ll look at it . If you can run your PHP program from the command-line and you install gdb you can run it under gdb and it will show you a stack dump of where the problem occurred . Just do gdb path to php then type r myscript.php and enter to run it and when it segfaults you can use the bt backtrace command to show the stack . That should identify which code is causing the segfault although it is not necessarily that code which is fault e.g . if php passed a pointer to a buffer of 10 bytes but lies and says it is 100 bytes the code which writes off the end is not at fault .", "Question : I have a problem where-by I cannot get Perl DBD : : ODBC to use unixODBC after re-compiling and re-installing . It had been previously installed . I had compiled DBD : : ODBC to use the DataDirect ODBC Driver Manager . I now want to recompile it to use unixODBC . However despite starting with fresh source configuring it picks up unixODBC and then compiling and installing it seems to be stuck using the DataDirect ODBC Driver Manager . I ve gone as far as deleting all the files I know of from the Perl module folders but the problem remains when it s reinstalled . I m compiling from source because the server I m installing on doesn t have an Internet connection so I haven t been using CPAN . I m using unixODBC 1.2.3 with Perl 5.8.4 it matches the environment on Solaris 10 . I ve removed all I can find : .. . .. . I then removed all entries for DBD : : ODBC in perllocal.pod . I can see when I run perl Makefile.PL that it is finding unixODBC . Here are all environment-variables relating to ODBC in the environment on which I m compiling and installing the module .. . .. . When I run a test I still see an error from the DataDirect driver manager : .. . .. . Ignore the fact that it can t find the driver because odbc.ini isn t populated . I m testing with a junk connection because I want to see this same error message from unixODBC . The Perl script I m using for testing is below . It works with the DataDirect driver manager .

Thanks . Comment : In the past I have used unixodbc along with freetds . and I would do connectivity test using tql and isql before moving on to perl . Check one of my answers from another post if it helps you : stackoverflow.com a 21252539 1251660 http : stackoverflow.com a 21252539 1251660 Comment : Thanks @slayedbylucifer but there is no connectivity issue using isql that comes with unixODBC . I m not even getting to the point of connectivity as a result-of DBD : : ODBC not referencing the correct driver manager . .. . Answer : You didn t say if you did a make install at the end of the build but I ll assume you did . You didn t say if those LD LIBRARY xx env vars are just set or exported as well . Firstly addressing other comments . 1 . DBI : ODBC : dsn should indeed be dbi : ODBC : dsn . 2 . Perl DBI does load the driver based on the string after dbi : so ODBC loads the DBD : : ODBC module . 3 . It is at the time of DBD : : ODBC configuration that it selects which ODBC driver manager to use is not correct . Configuration only selects the driver manager to compile against . I don t believe a runpath instruction to the linker is provided at link time . So you could happily build against unixODBC and run against DD which you seem to be doing . Find ODBC.so in your Perl tree it should be in a dir called DBD ODBC something like home martin perl5 perlbrew perls perl-5.19.10 lib site perl 5.19.10 x86 64-linux auto DBD ODBC ODBC.so . Now run ldd ODBC.so on it and look to see in the output where the libodbc.so comes from e.g . : .. . .. . Here the dynamic linker is resolving the dependency on libodbc.so.1 with usr local lib libodbc.so.1 . You need to tell the dynamic linker to look in your unixODBC lib dir before wherever it is looking now . Using LD LIBRARY PATH might not work - especially if you run as root and there are global ways of telling the dynamic liker where to look . Read your ld.so.1 section 1 man page . Comment : That s a lot of good information coming from the Author himself . Thanks . +1 . Comment : Sorry I haven t checked this out yet . I ve been very busy and now sick . I ll give this a try in a couple of days and let you know . Thanks for your response . Comment : Ahh yes very interesting . Nothing wrong with LD LIBRARY PATH as such but because ODBC.so is 32-bit and the ODBC driver manager we were using was 64-bit it was bypassing the drivers from the driver manager and didn t find libodbc.so until it got all the way to the last entry in LD LIBRARY PATH which was usr lib . Comment : ldd usr perl5 site perl 5.8.4 sun4-solaris-64int auto DBD ODBC ODBC.so libodbc.so usr local unixODBC sp32 lib libodbc.so libodbc.so VERS 3.52 version not found libthread.so.1 usr lib libthread.so.1 libc.so.1 usr lib libc.so.1 libgcc s.so.1 usr sfw lib libgcc s.so.1 libm.so.2 usr lib libm.so.2 lib libm libm hwcap1.so.2 platform sun4v lib libc psr.so.1 Comment : It s got a different problem if I use the 32-bit driver manager that I ll have to look into but it looks like you ve got me on the right track . Thanks . I ll pass on the results . I think something has changed because now it s not finding the version of libodbc.so that it wants it did when I tested earlier but something must have changed . It looks like I m close to a solution with your help though possibly we now face more complication than we thought with 32-bit vs 64-bit .", "Question : I m trying to set up unixodbc on OSX 10.7.3 but it looks like iODBC is on the way .

Answer : One thing to check is the minor version numbers of the unixODBC libs that the driver is linked against . Since unixODBC 2.3.1 I changed the minor lib number to 2 to reflect the change in the SQLLEN size on 64 bit platforms . However if the driver lib was linked against a earlier version it will be looking for a libodbc.so.1 and current sources provide libodbc.so.2 . Simple solution is to provide a sym link from the .so.1 to the .so.2 .

Answer : Since you progammed your application in C using WinForms I assume you used a PrintDocument and your printing takes place in a PrintPage event using PrintPageEventArgs.Graphics . If this is the case it should be possible to refractor the code which prints into a seperate method which takes a an instance of Graphics as parameter and probably additional parameters like page-size and so on . Then you could create a white Bitmap object with sufficient size and the same aspect-ratio as your paper and supply it to the method described above . Then you can go and count the pixels which have been colored and thus caculate the percentage of the page which the printer would have printed on . Keep in mind that you probably have to respect the margin around the printing area and different paper sizes for your calculation . If the refractoring of the code prooves to heavy you could create a wrapper for the Graphics object which duplicates all draw calls to a Bitmap while printing and then continue with counting the pixels .

You can quote it if necessary : .. . .. . Note that in Perl you can always use forward slashes for directories even on Windows and this is preferred because it avoids messy escaping issues . On Windows the path in the shebang line is not normally used for execution . Thus the convention is often to use usr bin perl for compatibility with Linux .

Answer : Is this the dependecy problem .. . .. . Yes usually . If you had deployed this module from a built version that you found on CPAN inc : : Module : : Install would have been bundled with that module in its inc directory . However because you re using the source checkout you need to have the pre-requisites locally .

On active Perl you could probably use CPAN.pm that comes with it but I m out of touch how that works and cpanm is a valuable investment . But basically yes you have a dependency problem .

Download and install latest xampp to G : xampp . As of 2010 03 12 this is 1.7.3 . 2 . Download the zip of xampp-win32-1.7.0.zip which is the latest xampp distro without php-5.3 . Extract somewhere e.g . G : xampp-win32-1.7.0 .. . 3 . Remove directory G : xampp php .. . 4 . Remove G : xampp apache-modules php5apache2 2.dll and php5apache2 2 filter.dll .. . 5 . Copy G : xampp-win32-1.7.0 xampp php to G : xampp php . 6 . Copy G : xampp-win32-1.7.0 xampp apache bin php to G : xampp apache bin .. . 7 . Edit G : xampp apache conf extra httpd-xampp.conf . Immediately after the line IfModule alias module add the lines .. . .. . snip .. . .. . Note that this is taken from the same file in the 1.7.0 xampp distribution . If you run into trouble check that conf file and make the new one match it . You should then be able to start the apache server with PHP 5.2.8 . You can tail the G : xampp apache logs error.log file to see whether there are any errors on startup . If not you should be able to see the XAMPP splash-screen when you navigate to localhost .

Answer : Runtime environment can consist of several things . http : en.wikipedia.org wiki Run-time system talks about some code that runs before the program that you wrote actually gets executed . They come in various levels of complexity . The C runtime on Windows will do things like create a Process and a Thread for a console app grab and prepare any environment-variables etc and call the int main argc argv function . However Java and .NET runtime systems do a lot more : they instantiate virtual-machine memory managed environments . These have many threads one of which will be running your code at some point . In Java the runtime environment can be interacted with via the java.lang type objects like Thread . In C on Windows or Linux one uses external libraries to do this . So runtime environments may provide functionality in some cases but not in others . Probably one of the very few software systems that do not have a runtime environment is the bare-to-the-metal embedded systems exmaple . This is where C code is written knowing that there is NO operating-system scheduler concept of a Process or Thread DOS prompt memory manager anything . There is however usually some boilerplate C code that is linked in and run immediately before the main entry-point is executed . This is probably written in assembler and initialises a Stack . Re XAMPP this is not really a runtime environment because it is merely a set of server packages . Any code you write is either in PHP Perl or code inside the MySQL db . PHP and Perl arguably have runtime environments of their own in which the script code runs . But no XAMPP i d say is not a runtime environment . ASP.NET and Java Server Pages or whatever it s called nowadays - the server-side Java stuff which used to be in Glassfish - Java EE that s it provide runtime environments to code that you write .", "Question : I am using XAMPP package in my own desktop with Window 7 as OS .

This adds an expired header to the files which is Ok but I m looking for the other ways to load them faster if there is an one . Comment : Until the browser has cached the item the first load will always be longer . If you consistently see long load times then you should watch the network requests with the browser s dev tools for your fonts to verify that those items really are using the cached copy . Comment : I think the browser never caches these items actually . Here a picture shows the load times of the fonts after the second load of the page dbhub.blob.core.windows.net live stack.PNG https : dbhub.blob.core.windows.net live stack.PNG Comment : So examine the network headers for those items to be sure you ve setup caching correctly .

Is it the http response time . Or is it the time page takes to load render completely on client browser once after it receives the response from the Server . What is measured generally across the industry . Do you have any recommendations in terms which should be done when Do you have any tool recommendations for the same . Can I use the Visual Studio Web Tests to measure the performance in terms of Web page load render time once after client receives the response . or its just the http response time . .. . Answer : In three words : Performance really matters .. . .. . My golden rule is pretty simple : You have to measure everything and optimize everything . It s not only a pure tech challenge but also concerns your business team . Here are some classic exemples from Velocity Conf . Bing A page that was 2 seconds slower resulted in a 4.3 drop in revenue user . Google A 400 millisecond delay caused a 0.59 drop in searches user . Yahoo A 400 milliseconds slowdown resulted in a 5-9 drop in full-page traffic . Shopzilla Speeding up their site by 5 seconds increased the conversion rate 7-12 doubled the number of sessions from search-engine marketing and cut the number of required servers in half . Mozilla Shaving 2.2 seconds off their landing pages increased download conversions by 15.4 which they estimate will result in 60 million more Firefox downloads per year . Netflix Adopting a single optimization gzip compression resulted in a 13-25 speedup and cut their outbound network traffic by 50 . What is measured generally across the industry . Do you have any recommendations in terms which should be done when From Steve Souders pioneer in Web Performance Optimization 80-90 of the end-user response time is spent on the frontend Start here first : Too many requests non-optimized images un-minified content js css do not distribute static throught a cdn are common errros . On the other hand do not forget your backend because this part really depends on load activity . Some sites are paying the largest amount of performance tax due to backend issues . As the page generation time increases proportionally to the user load You have to find the throughput peak of your app and check if it s ok with your -own- SLA . Do you have any tool recommendations for the same There is no magic tool that covers all topics but many great tools that will help for a specific part of your app . Page Rendering : Google Chrome SpeedTracer or IE 11 UI Responsiveness tool .. . FrontEnd : PageSpeed YSlow WebPageTest.org online GtMetrix online Pingdom online .. . Backend : asp.net Mini-Profiler Glimpse Visual Studio Profiler Visual Studio Web Load Tests .. . Google Analytics for RUM Real User Monitoring .. . .. . Can I use the Visual Studio Web Tests to measure the performance in terms of Web page load render time once after client receives the response . or its just the http response time . No Visual Studio Web Load Test focus only on HTTP request . Javascript is not executed and virtual users are not virtual browsers : it s impossible to measure page laod redner time .

Another interested link is from Jeff Atwood co-founder of StackOverflow Performance is a feature http : www.codinghorror.com blog 2011 06 performance-is-a-feature.html . Performance is a vast topic and I only cover here only a small part but you have a good starting point .", "Question : null .. . Answer : I have my cakePHP application hosted on centOS 7 monitored by appdynamics APM . In their monitoring controller I have breakdown of transactions that take too long . I also installed a simple chrome page timing plugin . On one of my webpages I got the following results : .. . .. . enter image description here http : i.stack.imgur.com JvfpT.png .. . .. . As you can see the page loaded after 157 seconds However in my APM the slowest Transaction recorded has execution-time at 2.1 seconds . If my server serves the pages in under 2 seconds and usually in around 0.5 second where does this terrible 157 seconds come from How can I monitor the source of that load-time Thats another example with firefox plugin for page load times : .. . .. . enter image description here http : i.stack.imgur.com a05Mx.jpg .. . .. . This one took nearly 54 seconds and thats a real load-time saw it mysekf . However firefox Firebug under Net tab shows that for that same page : .. . .. . enter image description here http : i.stack.imgur.com OP3gs.jpg .. . .. . 6 seconds for that same request Why are they so different and why is firebug incorrect I saw myself that the load took over 50 seconds Comment : if you are sure the time the php script takes to execute is at most 2 seconds - the answer is the webserver . Look at your apache config logs . I don t know what that image means btw - it looks to mean it took 100s to parse the dom . Chrome has it s own dev tools which don t look like that. . Comment : I attached firefox timings . Seems like parsing the content takes that long thats why nothing is showing up in my APM . Is it possible to debug what is taking that long since firebug doesnt even see this horrible load times Comment : There are a lot of variable in play here.Just because your PHP code can execute a request in 2s doesn t mean that is how long it take the client to download the content and get to an onload event . The size of the content the connection speed the physical distance between server and client any javascript that may be exeucting and causing browser to block before onload event etc . all come into play here . You will need to go through and eliminate all these possibilities to get to your answer . You should also necessarily expect to see discrepencies between metrics and server and at client Comment : I would start be investigating what javascript is running between primary response being served and the onload event as this looks like the most likely candidate as to where time is being spent . FYI you are also not showing the size of the primary request response here . That is also likely important .

This spec supported http : caniuse.com feat nav-timing in IE9+ FF7+ and Chrome6+ exposes page load timings eg DNS TCP connect request response and DOM timings through the browser s DOM . This can allow you to get millisecond-accurate page load timings for every visitor that comes to your site in a modern browser . It exposes all of these metrics on the timeline : enter image description here http : i.stack.imgur.com RpVrQ.png .. . .. . Now that these metrics are exposed there are several ways you could consume them . For a DIY solution Boomerang https : github.com lognormal boomerang is a third party library that uses NavigationTiming in modern browsers to ping this data back to your datacenter . For older browsers it has some cool tricks that monitor page-to-page navigations within your site to determine how long page loads take . If you re not interested in figuring all of the Boomerang stuff out there are several other service providers that use NavigationTiming and similar data to report page load performance data such as Google Analytics http : www.google.com analytics New Relic https : newrelic.com Pingdom http : pingdom.com and Speedcurve http : speedcurve.com .

Comment : Sorry Luke it s just that you said I want to show the users.. . I wasn t trying to be rude . : .. . Answer : You need two times : the starttime and the endtime . Using JavaScript the starttime can only be approximated because the script will only fire when it is loaded not before . This means that you will not measure stuff like DNS looking initial latency and initial downloading . If you re fine with this limitation do this : .. . .. . 1 . In the head of the page determine the current time using an inline script .. . 2 . On the firing of the onload determine the current time again .. . 3 . subtract the first time from the second and then you have the total time it took to load the page .. . .. .

I have a lot of ckeditors because each one is for one variable . Unfortunately an input text field is too small for the data requested . The problem is that it takes too long for the web page to load and sometimes the web page hangs . I m currently loading almost 425 editors . Here s an example of my code for three : .. . .. . I followed the performance guidelines http : ckeditor.com blog CKEditor-Loading-performance-details on ckeditor searched Stackoverflow for answers and it still isn t working . I even have the ckeditor toolbar minimized to just one row . I figure there has to be a way to load the ckeditors without having to load ALL the ckeditors and the contentCss when the page loads but when the ckeditor is needed . Any help would be greatly appreciated . .. . Answer : but the total number of ckeditors on the web page is almost 425 . Have you ever tried to open any application 425 times at the same time 425 tab in your browser 425 Wordpads 425 of whatever I don t think so . So the answer is very short - you re doing it wrong . You should not initialize all editors at once . Load them on demand when needed and destroy when not needed . User can t edit 425 text at the same time anyway . The longer answer is that classic editor http : docs.ckeditor.com guide dev framed is the heaviest one because it uses iframe . So when you initialize 425 you initialize 425 iframes . Inline editors http : docs.ckeditor.com guide dev inline are much lighter . There s also a divarea http : ckeditor.com addon divarea plugin which makes the classic editor use inline editable element instead of iframe so it s lighter too . But the answer is still - you re doing it wrong . Comment : Load them on demand when needed and destroy when not needed .

Now the only problem I have is the contentedible true is turned into contentedible false when I click the 186 ckeditor and the ckeditor does not load at all but if I delete some of the previous inline editors listed - the ckeditors that didn t work now work so its probably a number thing in the ckeditor.js file .

Comment : Recently I answered similar question http : stackoverflow.com a 27486666 2072035 and come to conclusion that CherryPy caches files by default . Caches in sense of sending headers that allow a browser to cache content . tools.caching is for in-process memory caching I don t think it s good idea for static content . Can you show us the round trip headers for your bootstrap.min.css . .. . Answer : You must have omitted some headers and some configuration . CherryPy sends Vary : Accept-Encoding only for gzipped responses . Normally it sends Last-Modified Content-Type Content-Length and some others . Also note that Cache-Control : max-age 0 means you do a refresh request asking server to validate the resource . In the answer http : stackoverflow.com a 27486666 2072035 I linked in the comment I showed that normally 304 Not Modified only costs CherryPy a os.stat call which is instant unless your disk is broken . What I suggest you to do is to run a separate CherryPy app on the same static directory with only tools.staticdir on to avoid possible misconfiguration session lock issues etc .

The Blog feature must not be activated on the Blog site itself but on te Personal Site Collection .. .

It will go to a new URL which is seems to be a new site collection URL . So newly created site collection doesn t inherit the master page . Is there is a way to stop this means to stop a new site collection creation for each users .. . Answer : Well it is normal that new site collections are created for each user . It is used to store their Tasks list their My Documents library and other personal stuff . If you want to prevent users from creating these site collections you can deny them the right Create Personal Site in the User Profile Service see this blog post for instance : http : www.toddklindt.com blog Lists Posts Post.aspx ID 222 . However you loose all related functionnality of course . However these site collections should all use the same master page . So if your Sharepoint is not heavily customized you can simple modify this masterpage . Comment : Hey Matthieu thanx for clarification on this . But these site collections however isn t using the same master page . I modify the master page on my account and its working but whenever a new creates mysite . This master page doesn t apply to their site . Please help.. . Comment : How are you modifying your masterpage I suggest you don t use Sharepoint Designer this will modify your own masterpage only . Create a custom masterpage instead and deploy it to your farm through a solution .

I guess getting the accountname from the query-string will be your only option Comment : As Nacht writes in his post there is no accountname query-string when you are on your own MySite so you need to account for both cases in the code : When on somebody else MySite use the querystring and when on the currents users MySite the querystring is empty so then look in the SPContext for the logged on user .

As ratchet freak mentioned D does have std.encoding http : dlang.org phobos std encoding.html but it does not cover many encodings at the moment .

You can cast a IConnection instance into an Apahce.NMS.ActiveMQ.Connection and then call DeleteDestination . This would work if there were no consumers on the Queue but will throw an exception if there are . Comment : I wish NMS included a management API but for now this accomplishes what I needed . Thanks for the tip Tim Comment : Its not possible for NMS to include a management API as the broker is java based and managed via JMX . If you want to create an open-source library to communicate with JMX via .NET then we can but until then there s a limit to what can be done in NMS based clients . You could write some java based libraries to perform the management tasks you need and run them via IKVM in you .NET app I suppose .

This separate processor then uses the reply-to queue name and correlation ID to craft the response and sending it to the original requester on the same broker but a different connection . The problem is that it appears you can only send to a temporary queue or topic if you have the IDestination object-reference from the message s NMSReplyTo header .

Comment : Thank you for your answer . But if an issue occurs how would I know that one occurred What will happen Would I be save if I make a checksum from my byte message and send it with the message You wrote should work without any issue . Comment : The message body and the properties are distinct data sets in ActiveMQ so setting a property has no effect on the body of the message .

Answer : I would recommend using a topic as a reply destination and have your consumer filter based on the NMSCorrelationID . This is the implementation I have moved to after much frustration with temp queues . It actually has-many advantages . 1 . It cuts down on intensive resource usage on the server no need to construct deconstruct temp queues . 2 . It allows you to use another consumer to monitor the response sent back you will never be able to peek inside a temp queue . 3 . And it is much more reliable because the topic can be passed via a logical name instead of a specific token ID which you are losing across connections .", "Question : Quoting from EIP patterns book from Hohpe G . and Woolf B . : .. . .. . Note that in JMS an Event-Driven Consumer that is also a Transactional Client will not work as expected . Normally a transaction is rolled back when the code in the transaction throws an exception but the MessageListener.onMessage signiture does not provide for an exception being thrown such as JMSException and a runtime exception is considered programmer error . If a runtime exception occurs the JMS provider responds by delivering the next message so the message that caused the exception is lost.To successfully achieve transaction event-driven behavior use a message-driven EJB . I understand that but what if I m using Apache NMS ActiveMQ from a .Net Client I don t have MDB so how should I adress this issue .. . Answer : The ActiveMQ NMS client async consumer functions in essentially the same way as the Java version . You should handle exceptions in you callback since they are treated as programmer error in NMS as well and the next message is delivered when in a transaction .

The temporary queues are deleted as soon as the client disconnects closes the browser etc . which is fine since that s why I m using temporary queues . however I store the destinations on the server so i can send certain messages to certain destinations WHILE they are still connected . everything works great until a client leaves closes the browser which means ActiveMQ will remove the temporary queue and I need to stop sending messages to that temporary queue until they reconnect because if I try i get this exception : .. . .. . javax.jms.JMSException : The destination temp-queue : ID : WIN-HP6U1SD1FB4-29628-1329687650640-0 : 1 : 85 does not exist . which makes total sense cuz the temp queue is gone since they left the page or closed the browser . But here s the kicker that kills me - after this exception which I catch the entire messaging system goes down activemq just no longer sends messages until i restart it . this seems absolutely crazy unless i am missing something very fundamental in how i m using it . basically what i can t figure out is : .. . .. . 1 why does activeMQ go down when it tries to send a message to a temp queue dest that doesn t exist why can t it just throw the exception and continue 2 fine I can live with 1 but how do i check if a temp destination queue exists before i send it nothing in the API seems to support this . 3 if 2 for some crazy reason isn t possible how do I recover from this jms exception that brings down the entire message-queue system I d post code but not sure that would help here . .. . Answer : I think you ve run into an NMS bug that has been resolved recently see https : issues.apache.org jira browse AMQNET-377 . If you update to version 1.5.5 or later you should have better results .", "Question : I just started with the ActiveMQ thing and got several questions . I should send messages using ActiveMQ .. . .. . What I did for now : .. . .. . There will be only one instance of this class which will be injected as a constructor parameter . I am affraid of overhead for connection session and producer creation because messages will be sent frequently often than one message per 10 seconds Should I reuse connection session or producer instances and how should I react to the connection failures What is the common pattern in such scenarios .. . Answer : NMS.ActiveMQ like the java client provides a failover transport which will automatically attempt to reconnect to the broker should the connection be lost . You can use that to minimize you failure handling code . Do some Google searching on the topic of failover transport in AMQ . Recreating the connection and associated resources is not a lightweight operation so you re best bet is to cache them and reuse them for as long as you need that connection . In combination with failover you can reliably reuse the same MessageProducer over and over . The model of NMS is much the same as JMS so doing some reading on JMS should provide enlightening .", "Question : We just hit an interesting error on our build-server when compiling some recent changes from the command-line : .. . .. . c : Windows Microsoft.NET Framework v3.5 MSBuild.exe .. . .. . error CS0246 : The type or namespace name var could not be found are you missing a using directive or an assembly reference Code in question : .. . .. . producerErrors is type of IMessageProducer http : activemq.apache.org nms msdoc 1.5.0 vs2005 html T Apache NMS IMessageProducer.htm from Apache.NMS http : activemq.apache.org nms nms.html .. . response is type of ITextMessage http : activemq.apache.org nms msdoc 1.5.0 vs2005 html T Apache NMS ITextMessage.htm .. . .. . Note that it successfully compiles from Visual Studio and I can reproduce the error locally from the command-line which I think rules out a configuration issue with the build-server . The fix is trivial of course but it s got me stumped as to why compilation is only failing from MSBuild command-line The project in question has other var keywords in use which are compiling just fine so I suspect it might be something to do with the Apache assembly but what Comment : Could you please describe how you fixed this problem Comment : The fix is replacing type-inference the var keyword with the actual type ITextMessage . Comment : Oh trivial . Looking for better solution without touching the code . Anyway thank you for the answer : Comment : Yes trivial fix - but still a mystery as to why type-inference is failing . .. . Answer : Are you entirely sure you don t have a 2.0 compiler in your 3.5 directory by accident Comment : Yes - The project in question has other var keywords in use which are compiling just fine Comment : This boggles the mind.. .", "Question : I am integrating with an ActiveMQ JMS system using the Apache.NMS library . For the response queue listener it s not clear whether the consumer is disposed after a message is received . Here are excerpts from the solution : .. . .. . Is the consumer durable Do you have to resubscribe after receiving a message Is this similar to other queuing listener implementations SQL Server service broker or the TCP IP listener where you need a while true loop to just keep the listener active .. . Answer : Because of the way you ve coded this I believe my .NET is rusty you would need to create a new listener on each message as the using block will dispose of the consumer . If you coded things such that the consumer was a member variable where it was saved away and only closed when you wanted to stop listening then you would not have this issue . The using block by it s nature will dispose of the resources that you ask it to manage . Comment : Thanks . I ve changed it to hold the connection session and consumer as fields of my receiver class which implements IDisposable . I clean up these fields during dispose . Does this mean the Listener event will fire for each message without a while-loop Comment : If you code it correctly is should that is the whole point of using the async listener pattern . Best way to know is to ask the computer .", "Question : I m planning on using Apache NMS for ActiveMQ messaging and am wondering what serialization method is going to be used on the objects I send XML Binary What controls the serialization and how can I customize it Does anyone have experience doing this with C objects Are there any pitfalls that you know of .. . Answer : The default is System.Runtime.Serialization.Formatters.Binary.BinaryFormatter for IObjectMessage . You can set your own by e.g . You d need to set the formatter before accessing IObjectMessage.Body on the receiver side if you re not sending objects with the default BinaryFormatter . If you wish you can also send receive IByteMessage ITextMessage and serialize your objects to the messages yourself in any way you d like . Comment : Any good info on the backward compatibility of the binary format What happens with a removed added field Comment : Seems in practice in my limited experience atleat missing fileds just get their default values . This serialization has nothing to do with NMS ActiveMQ though . There s lots of questions regarding serialization on stackoverflow poke around those .", "Question : I have problems setting message priorities via nms . The messages are sent to the queue everything is ok but the priority is ignored . I use the following code : .. . .. . Regardless what value I set for message priority using the ActiveMQ browser I can see that the priority is always set to 4 . I also tried to add some raw headers like : .. . .. . But it doesn t help . I also have added the attribute .. . .. . to the activemq.xml file . And I can send a message with priority manually via the ActiveMQ browser . So where is the problem What I am doing wrong .. . Answer : Message priority is always set by the producer that sends the Message . The setter on the class will only allow you to change the value after you ve received a message and is usually only used for unit-testing or converting Messages between providers . To set Message priority on a per message basis have a look at the different send methods in the MessageProducer interface . Comment : Thank you very much your answer solved my problem But it is interesting that I can set the message properties via the setter class and other things too but not the priority . Comment : You can refer to the JMS API documentation on things like this the various setters are tagged to indicate which one s are not applicable to sent Messages" ] }

My applet has been online for several years with no reported errors . When I downgrade to version 6 Update 21 everything works perfect . My applet is not signed . SOLUTION : It took me ha while to find the cause of the problem . Actually in my case there were several factors causing the security error . The problem was solved by the crossdomain.xml file . The Java applet tried to download the crossdomain file failed and did not even bother to display an error in the java console debug level 5 . Java tried to download the file from the ip adress of my domain http : ip-address crossdomain.xml and not the root of my website http : domain-name crossdomain.xml . I guess it is better for the security aspect I then had to configure the webserver to expose the crossdomainfile on the IP address . In my case I have removed the default website in ISS for security reasons and had to create a new website . I then discovered that the java applet did not work with the crossdomain files i use with flash : .. . .. .

The problem is that Java applet code called from JavaScript has only permissions that are the intersection of the JavaScript s code and your applet code - and somehow the JavaScript s permissions are seen as less which results in this Exception . Here is what I did : assume you have a function innocentFunc that throws the java.net.SocketPermission exception so your code is something like so : .. . .. . Now what you can do is to change it to something like so : .. . .. . This AccessController call basically states to the Java Virtual Machine that the code it runs should not obey to the permissions from the call chain but rather only the caller s permissions in its own . Of course you should do something like this only after making sure that this innocentFunc call can t do anything bad even if invoked by malicious code .

Thanks", "Question : Firstly thanks for your time . I have a serious concern about Live Connect s OAuth2 API . I follows this and using DotNetOpenAuth to implement integrate LiveId authentication authorization for our federated-identity access management system . http : msdn.microsoft.com en-us library live hh243647.aspx authcodegrant .. . .. . Everything is working fine for quite a long time . But now I m having a serious trouble when fixing the replay attack issue for LiveId login module . Let s take a look at the Authorization code grant flow from the above article . 4 . The user-agent calls the client with the redirection URI which includes an authorization code and any local state that was provided by the client . For example : ...Callback.htm code AUTHORIZATION CODE . 5 . The client requests an access token from the authorization server s token endpoint by using its client credentials for authentication and includes the authorization code that was received in the previous step . The client includes the redirection URI that was used to obtain the authorization code for verification . .. . .. . Right after the step 4 Live Connect OAuth2 server returns to my callback endpoint with the authorization code state like the following : .. . .. . https : ssss.myapp.com : 443 liveid consume.idp code 406dd558-0cda-50cc-bd37-d964ec29fbb3 state uvygsnd3gba0jwi315kdyccs https : ssss.myapp.com : 443 liveid consume.idp code 406dd558-0cda-50cc-bd37-d964ec29fbb3 state uvygsnd3gba0jwi315kdyccs .. . .. . Problem is that authorization code could be used more than once . So it leads to the serious replay attack issue like the following scenario : .. . .. . 1 . User A when logging in to my application chose LiveId to sign-in then he s redirected to LiveId login page . He then logged in Live Connect OAuth2 server returned to the callback endpoint with the code xxx state yyy...user A then used this authorization code to obtain the access token.. . .. . .. . 2 . User B when logging in to my application chose LiveId to sign-in he then logged in at LiveId s login page . Live Connect OAuth2 server now return with code kkk state ggg .. . .. . If I this time use some tools like Webscarab to capture the response request then change the return from OAuth2 server to code xxx state ggg the old authorization code was given to user A not B . Then after that requesting for access token using this replay authorization code was going through smoothly . And guess what I received again the ACCESS TOKEN which was given to user A before...and finally user B can logging into my application as user A . Please be noticed that applying the same replay attacking like above for Google OAuth2 server I received bad request error from the server Google OAuth2 authorization code never could be used more than once . And the code flow or exactly the implementation for Google login LiveId login are exactly the same . I used DotNetOpenAuth.OAuth2.WebServerClient to implement the OAuth2 authenticating flow for both of Google LiveId . Again exactly the same code but Google OAuth2 server returned bad request when authorization code is reused but LiveId returned the old access token of the previous user . This is a serious security problem . Hope you guys have some ideas on this . Or hopefully I m wrong on some points . Please point it out . Thanks very much in advance Phuc Le . .. . Answer : The OAuth 2 spec is quite clear here https : tools.ietf.org html rfc6749 section-4.1.2 : .. . .. . If an authorization code is used more than once the authorization server MUST deny the request and SHOULD revoke when possible all tokens previously issued based on that authorization code . This is for the exact reasons https : tools.ietf.org html rfc6819 section-5.1.5.4 you mentioned above . In your case you should notify your provider http : technet.microsoft.com en-us security ff852094.aspx of this issue . Meanwhile you could implement a cache of used authorization codes on client-side and check for already issued codes . Note thate this could also produce false positives in the occasion that the provider randomly generated the same code for two different users which might be quite unlikely depending on the implementation . Comment : Thanks Gerlinger for the response Comment : Back to the issue . As specified in your link @ tools.ietf.org html rfc6819 section-5.1.5.4 https : tools.ietf.org html rfc6819 section-5.1.5.4 5.1.5.4 . Limit Number of Usages or One-Time Usage The authorization server may restrict the number of requests OR operations that can be performed with a certain token . This mechanism can be used to mitigate the following threats.. . As specified above I think the Live Connect OAuth 2.0 server chose the approach to limit the number of usage NOT one time usage . I will try to ask again in Live Connect forum to see if it s . Comment : About your solution that using cache to store the already-used authorization code for checking later . IMO that does not work for my case actually . Imagine that we have the application running on many servers which doesn t share anything to each other no central session or cache database....nothing shared . So maybe an authorization code is already used once in this instance server but not in others . Now hacker uses it for replay attacking another server instance there s actually no way to check . Please share you ideas Thanks a lot . Comment : @PhucLe As is specified in the spec it is not allowed to use authorization codes more than once . The sentence in the Threat Model spec aims for other tokens that could be prone to replay attacks . I just posted it to prove that limiting the usage or using one-time tokens is the recommended way to deal with replay attacks . In your scenario there s not much you can do about it than waiting for your provider to fix this issue or holding a common store for your servers . Comment : @Gerlinger : thanks that s what I thought too . It seems this need to be fixed by Live Connect OAuth 2.0 server team .

But I unable to show events on calendar . Any help will be appreciated.Thank you . .. . Answer : I m the author of MBCalendarKit .

Answer : Even though Parse is going away this question might help those with a different backend so here s the scoop . You don t create events in MBCalendarKit but in your own data model . Once you ve created your own data model and saved it to your local or remote data store you can update the calendar UI .

The state of each cell is determined based on if it s part of the current month or not if the cell is selected and if the cell has an active touch in it . Have a look at the applyColorsForState : method for the coloring and stuff . You may want to add your own borderRadius and clipsToBounds values .

Answer : From http : www.c99.org 2010 01 23 writing-an-android-sync-provider-part-1 : .. . .. . The first piece of the puzzle is called an Account Authenticator which defines how the user s account will appear in the Accounts Sync settings . Implementing an Account Authenticator requires 3 pieces : a service that returns a subclass of AbstractAccountAuthenticator from the onBind method an activity to prompt the user to enter their credentials and an xml file describing how your account should look when displayed to the user . You ll also need to add the android.permission.AUTHENTICATE ACCOUNTS permission to your AndroidManifest.xml . Comment : That s a good article but do you think the AccountManager is only for accounts that sync contacts and email or can should we use it for anything that has user IDs and passwords Comment : @Phil : I ve never used AccountManager so I can t tell you . Remember that this comes with 2.0 so if you are willing to run on devices with lower SDK you will have to find another way to handle login .

Answer : The AccountManager class is integrated with your phone accounts . So if you follow all the guides and get it working correctly you ll see your accounts under the menu Settings- accounts and sync . From there you can customize them or even delete them . Furthermore the accountManager has a cache of the authentication tickets for your accounts . This can be used also if you don t plan to synchronize your account as far as I know . If you don t want your accounts to appear under that menu you shouldn t use the AccountManager and store the accounts data elsewhere maybe in the shared preferences http : developer.android.com guide topics data data-storage.html", "Question : null .. .

As far as I know you can use the ContentProvider without the others . With AccountManager SyncAdapter ContentProvider : .. . .. . AccountManager gives users a central point Settings Accounts to define their credentials .. . Android decides when synchronization can be done via SyncAdapter . This can be good to optimize battery no sync is done when network is down for instance .. . ContentProvider is a convenient way to share data across applications Note : there are other methods of inter-process communication on Android http : developer.android.com training articles security-tips.html IPC . strike ContentProvider schedules the database access in a background-thread strike The AsyncQueryHanlder http : developer.android.com reference android content AsyncQueryHandler.html helps to query the ContentProvider in a background-thread preventing Application Not Responsive ANR errors while not requiring you to explicitly handle threading .

So far I know client should authenticate through OAuth there s also a java library for IMAP auth http : code.google.com p google-mail-xoauth-tools source browse trunk java com google-code samples xoauth XoauthAuthenticator.java by Google . But I d like to set user free from any password typing . Android provides a cool native way to gain authToken for google account services via AccountManager .

Or do I miss something Comment : I don t know for certain but I m sure GMail can be accessed via OAuth . I m using Chrome extensions which can do so . Comment : OAuth Certainly . The point was to use Account getAuthToken method and provided authToken for OAuth . But for Gmail it s seems to be impossible . Comment : Thanks for response . The problem remains . If scope-related problem is solved than next problem is to figure out how to use this authToken for servers where OAuth tokens are needed . .. . Answer : Have you tried using oauth2 : https : mail.google.com as the auth token type authTokenType parameter when calling AccountManager.getAutToken According what is said at 46 : 50 in the talk you mentioned http : www.google.com events io 2011 sessions best-practices-for-accessing-google-apis-on-android.html it should work . By the way this page http : googleappsdeveloper.blogspot.com 2011 08 using-google-tasks-api-and-oauth-20-on.html describes how to get an OAuth2 token for Google Tasks and it has a link-to a code sample http : code.google.com p google-api-java-client source browse tasks-android-sample src main java com google-api services samples tasks android TasksSample.java repo samples . It also makes it sounds like it is just a matter of providing the right authTokenType parameter . Comment : It should work and it works But only for ClientLogin library . Right When there are many reasons why Android client app should get OAuth tokens not those which AccountManager provides . And WebView seems to be the only way.. . Thanks for your answer Comment : If you use the authTokenType provided in the examples the token given by AccountManager should be an OAuth token . I must admit that I haven t tried it myself yet but the last code sample http : code.google.com p google-api-java-client source browse tasks-android-sample src main java com google-api services samples tasks android TasksSample.java repo samples seems explicit about this the token returned by the AccountManager is used with a oauth2.draft10.GoogleAccessProtectedResource .

I cannot easily believe that the framework can automatically remove the data my SyncAdapter has stored in the local database but it seems to imply that removing the account will and I would agree that is should remove that data . Is there a addition to my SyncAdapter that will serve sort of as the callback for the account removal to handle deleting all the appropriate data from the local database Maybe it has to be done through the AccountManager instead my AccountManager gets notified when the account gets removed and from there I can trigger the data deletion without the SyncAdapter . EDIT : On a related note is the sync manager calling my SyncAdapter for each account that it synchronizes when a new account is added I see a onPerformSync .. . being executed for previously added accounts along with the just added account when I add an account and would like to stop that . .. . Answer : Another option is to register for the android.accounts.LOGIN ACCOUNTS CHANGED broadcast that the AccountManager sends out . Unfortunately this broadcast is sent out whenever any account is changed and the broadcast does not deliver further information what has changed either . So you d have to query the account manager and look how many of your accounts it has left and delete the data of the missing ones . Comment : Well the solution above this by @Dandre Allison is based on this . So this answer should be preferred . When you call addOnAccountsUpdatedListener AccountManager is registering a dynamic broadcast receiver which call the listener in its onReceive . So it s basically the same . Both solutions are notified whenever any account in the device Google account Twitter account etc is changed .", "Question : I have inherited an app which comes as a free version and Pro monthly subscription is bought via in-app items .

The app suffers from a strange bug that it forgets the Pro state randomly either when you close the app or during the work . Is this a good way to store Pro status Could AccountManager be the reason why the app loses the idea of a Pro status I usually use either a database or SharedPreferences to store such data besides storing it on the remote API so I need a help from someone who used his app in the same way . .. . Answer : Usually the people playing with the setting pro status will be the one with rooted devices . Anyways the data stored in the account manager is visible to such users . So for such a use-case even account manager is not safe . Though other apps with different UID cannot access this data . Also keep in mind that the user can delete the account from the settings which might be the reason for your settings going away .

Answer : This accepted answer to this question would probably help you.. . Why Should I use android AccountManager http : stackoverflow.com questions 2720315 why-should-i-use-android-accountmanager .. . .. . It should also be pointed out as mentioned in the above post and also in AccountManager without a SyncAdapter http : stackoverflow.com questions 3085242 accountmanager-without-a-syncadapter that you can t have an AccountManager without a SyncAdapter so its probably not good to use this for your particular situation . I can t see any reason to use an AccountManager specifically for storing this type of information - at the end of the day its no different to manually storing the data yourself in your own database or file . If anything it probably complicates things - why don t you just store it in SharedPreferences The only reason I could think of that would encourage the use of AccountManager would be if you want to share your account across a number of different apps as the data is stored in the central Android datastore which can be accessed by all apps . However if this isn t required I think its probably easier and simpler to just use SharedPreferences Comment : Thanks thats great . I will most likely have a user table in sqlite since i m using sqlite for other stuff since I may allow multiple users to use the app on the same device . Comment : p.s . I have already seen this question first link but it didn t really speak to me . And no accepted answer sort of leaves it open to speculation.. . Comment : So an example of AccountManager is the interaction of let s say Facebook app and their messenger app for authentication Comment : This answer is exactly what you should avoid doing . Storing a password in a file or in a DB instead of in a secure place like an AccountManager is just exposing the password to any other app installed on the device .

Say I create multiple users for my application on a device and populate database with data that is relevant only to those two users . My problem here is that if one of the user is removed from Accounts sync settings I have no way to cleanup database and or some external files on SD card . I could duplicate user information in a redundant table and compare it with registered accounts and then removing user data from the database if user information in the table and Account array from AccountManager does not match .

The Android AccountManager stores only one auth token how could I save the second one Saving one token with the AccountManager and implementing some own storage logic for the other token would kind of render the whole use of AccountManager useless . I thought of combining the two tokens to one String seperated by some special char then saving that String to the AccountManager . Any better more elegant ideas on this .. . Answer : I don t quite get your question . If you want to store two kinds of tokens nicely you can just use different suffix of token keys when saving tokens to AccountManager . If you want to provide two tokens at the same time for AccountManager s getAuthToken API there could be several ways to do it . One way is the way you ve described that returns two tokens separated by a special char .

There is a lot of concurrency and threading but everything is initiated via the onAccountsUpdatedListener . .. . Answer : I am aware of one bug in Honeycomb plus that can cause your issue . If you try to getUserData of the account before it is registered all subsequent getUserData calls will return null . If you look at the code . AccountManager has an in-memory cache that is backed by a sqlite database . Calling getUserData populates the in-memory cache userdata even if it is not registered . If it is not registered it interprets that as no userdata . Registering an account only populates the database and does not invalidate the in-memory store . This may be causing your issue . The workaround is to remove the account before calling addAccountExplicitly . Ya this issue sucks and is a HUGE bug in AccountManger IMO and allows third parties to essence DOS your app . Comment : Thanks . I ve since re-engineered the code to get around it but if I remember correctly it had been occurring on pre-honeycomb devices as well as ICS devices too Nexus 1 Nexus S HTC Evo Samsung Skyrocket and a few more .

Answer : The Account object you get from AccountManager has a name field which is the user s email-address .

Answer : This is doable using OpenID Connect however it s sort of experimental so details could change in the future . If you get an OAuth token for the https : www.googleapis.com auth userinfo.email or https : www.googleapis.com auth userinfo.profile scope you can use it to get user info from https : www.googleapis.com oauth2 v1 userinfo including email . Of course the user needs to authorize this . You should theoretically be able to get the token from AcccountManager using the oauth2 : https : www.googleapis.com auth userinfo.profile as the token type but that doesn t appear to work on my device Galaxy Nexus with stock 4.0.4 .

Answer : Generally speaking containers should be used to implement services available to external applications an APIs service or a runtime or a dbms or something like that . According to this what you could achieve is a set of services available for you on different containers and a single container working as SSH tunnel gateway making your local environment connected to it using SSH and defining a set of local and remote SSH ports forwarding with different policies according to the service port and the IP of the service . It should work for all the services and you haven t to use a socks proxy to forward requests to different hosts : using remote SSH forwarding your SSH endpoint will redirect your requests to the right service inside the local private lan .

Just quite complicated for such a simple use-case - Comment : The containers network and the VM one are distinct due to infrastructure reasons .

Answer : Milton an open-source WebDAV library implemented in a Java Servlet which allows any data from your application to be exposed via WebDAV . Here s an example using Milton Hibernate and Tomcat together in which Milton running on Tomcat is used to provide WebDAV-based access to Hibernate data .

So I don t think I understand your comment .

I could try -9 and get more than 0.3 but I don t think it s worth it . Comment : That said there might be a possibility to specify the compression level of mp4 and if you d use something corresponding with zip -0 then you might get something compressible . However I guess that most of mp4 around is heavily compressed already .

Answer : I have never used Milton WebDAV before but from the looks of it it is used to modify and edit files on a server . However Azure s local-storage is not shared . Each instance is a completely seperate server . If you modify a file on 1 server it will not be replicated to the next . Azure works by uploading a deployment package . When a new instance needs to come up it uses the deployment package and starts a completely new server . From a your perspective they don t share anything in common . Because of this you will never know which server you are hitting . If you have a shared file storage system behind then it may be a different story . However that scenario looks odd from using Azure . Amazon EC2 with a shared EBS might do it though .", "Question : null .. .

Answer : Sorry for the late comment the two most important aspects of webdav which affect load-balancing are digest-authentication tokens Nonce values and lock tokens . As the Resource implementor you get to control both of those . Lock tokens are typically stored in a database you must implement the methods on LockableResource which will do the persistence so will be shared across servers although its not uncommon to use memory based lock tokens in which case you need to find some way to share that information across servers . Digest nonces are only a consideration if you ve implemented DigestResource . The default NonceProvider uses a simple HashMap so this will not be shared across servers . But the interface is trivial so you can easily implement a database store . If your load-balancing solution uses sticky sessions then that won t be an issue because clients will go to the server which has their nonce . Note that Tomcat session replication won t help with the above issues because webdav clients typically dont support cookies so there is no Servlet session .", "Question : null .. . Answer : With our project we are trying to implement Milton in combination with a jetty based cloud . The problem we have is that the cloud slot can only be stopped and started we cannot change any configuration . We do have the ability to add libraries to the cloud node but we are having difficulties initializing Milton after the server has already started . My question is is there ay possibility to start initialize Milton after the Java server has already been started If not what makes it impossible to do so", "Question : I am in the process of testing a web dav enabled view my system using anumber of different clients . One particular client seems to do sometimes do strange things and I was wonder is this to be expected. . The log below shows how it has somehow mangled the path to the directory collection in webdav speak by including again the full path to the servlet again look at the last line . All other clients dont do this is this primarily because its a poorly coded client that is probably broken I have looked at the response log that the client makes available and the names are not mangled they make sense . and not .. . Answer : It is most likely the client . - what it looks like is that the server is replying with a fully qualified URL with scheme host and port http : 127.0.0.1 9000 but the client is treating it as a relative uri href - milton abc and prepending the info back on it . Returning href s like milton abc is often used but both are legal .

This is my upload PUT method code : .. . .. . and this is the output : .. . .. . How can i increase the read size of InputStream in milton server I can not change InputStream to any other type like BufferedInputStream In my local computer uploa speed is 27KB s and this is too slow .. . Answer : There s no reason why that code should be fast or slow . Bytes will be received at the rate they re provided by the network adapter and using a BufferedInputStream won t help because bytes are already effectively by the network adapter . I m very surprised to see local upload speed of 27KB s I ve never seen antthing that slow before . I just did a quick test on the milton server i m currently working on which does very complex processing of files including chunking and SHA1 calculation and it gave the following results : UPLOAD time 8541ms SIZE 82 954 392bytes bandwidth 9 712 491bytes sec .. . .. . How have you tested the upload speed was that from the client or at the server You can get apparently slow uploads sometimes when measured from the client because of high latency of all the PROPFIND requests the client does before and after the actual upload . That should not be a factor for large-files though Eg 50Mb or more . If you re testing with Win7 make sure you have cookie authentication enabled otherwise Windows will do every upload twice first without credentials then again with credentials .

Conclusion : The framework is amazingly straightforward and flexible and allowed us to use it in ways that authors never even thought of .. . .. . As for the price : it turned out to be totally worth the money . Plus the support is just beyond awesome . Comment : Just FYI we ve released a new version of WebSync WebSync 3 which has massively improved documentation api.frozenmountain.com http : api.frozenmountain.com and also adds more flexibility to the JavaScript framework by 1 arranging better namespaces so functionality is better segregated for example we have fm.network.jsonp fm.network.xhr fm.json etc and 2 supporting extensions api.frozenmountain.com class getting-started-server-extensions http : api.frozenmountain.com class getting-started-server-extensions . Hopefully that ll help with some concerns .. . Answer : I ll leave it to someone else to post their thoughts on their use of WebSync but I figured I d at least attempt to address the cons .. . .. . 1 Relative to open-source solutions sure . But what you pay in up front costs IMHO you ll easily make up for due to ease of use and time of implementation : . I don t think you ll find a comet solution that s faster or simpler to implement . Relative to other closed-source solutions we re pretty darn cheap some other comet solutions run 20k+ for a license and require support subscriptions . 2 Yeah I know that one . The examples and documentation cover the basics and it s enough to pull together a decent app but doesn t go into enough detail for more advanced scenarios etc . We re working on upgrading it . 3 I d love to know what additional flexibility you d like to see in the javascript-framework was there something in particular you were looking for Drop a note in the comments Comment : Glad to hear . The framework is nice but a lot of things are not a part of the API although they are present in the DLLs I dug in with reflector . Can t discuss specifics of the project but it would be nice if it was possible to pass data with a subscribe message for instance . Comment : Yeah as mentioned we re working on cleaning up the API documentation especially for the .NET client it ll be a lot better in the next release . RE : passing data with a subscribe message you can use the ext parameter for that check out the documentation for ext here : frozenmountain.com websync support documentation http : www.frozenmountain.com websync support documentation clients javascript-using-subscribe Comment : One more question . There is onReceive handler in the subscribe function but how do I send data to it from my server-side handler I have tried setting message.Data but with no result . Comment : I m not sure I m following what you re attempting 100 but if you re looking to override the data in the incoming message you re doing it correctly just make sure you specifiy EventContinue.OnComplete and call e.Complete in your method if not WebSync is set up to err on the side of performance and your server-side handler will execute asynchronously and won t change the data until it s too late : You can also just use NameOfYourHandlerClass .DirectPublish channel data to push data from the server-side .

Answer : In WebSync 4 you can skip the .ashx handler altogether and just add a route for WebSync directly in Global.asax :", "Question : I am using Websync3 Javascript API and subscribing to approximately 9 different channels on one page . Firefox and Chrome have no problems but IE9 is throwing an alert error stating The request is too large for IE to process properly . Unfortunately the internet has little to no information on this . So does anyone have any clues as to how to remedy this .. . Answer : This error occurs when WebSync is using the JSON-P protocol for transfers . This is mostly just for IE cross-domain environments . Meaning websync is on a different domain than your webpage is being served from . So IE doesn t want do make regular XHR requests for security reasons . JSON-P basically encodes the up-stream data your 9 channel subscriptions as a URL encoded string that is tacked onto a regular request to the server . The server is supposed to interpret that URL-encoded string and send back the response as a JavaScript block that gets executed by the page . This works fine except that IE also has a limit on the overall request URL for an HTTP request of roughly 2kb . So if you pack too much into a single request to WebSync you might exceed this 2kb upstream limit . The easiest solution is to either split up your WebSync requests into small pieces ie : subscribe to only a few channels at a time in JavaScript or to subscribe to one master channel and then program a WebSync BeforeSubscribe event that watches for that channel and re-writes the subscription channel list . I suspect because you have a key in you example source above you are using WebSync On-Demand If that s the case the only way to make a BeforeSubscribe event handler is to create a WebSync proxy . Comment : As of WebSync 4 JSON-P is only used in IE7 and below . Newer techniques postMessage CORS WebSockets etc . can be used in IE8+ .", "Question : I am using IceLink library for peer to peer communication . We need to deploy two servers IceLink and WebSync for that as listed here http : docs.frozenmountain.com icelink2 index.html class icelink-getting-started-creating-a-conference-10 ios-macosx But I want to use XMPP instead of WebSync . Following code is used for WebSync now I just want to replace it so that I can use XMPP instead if this WebSync . .. . Answer : There is no question here . At any rate as a general answer to future readers you can use literally any method of communication between the clients . You could even email and copy-paste the information that s sent over the signalling channel something I actually did for my earliest WebRTC stuff to avoid the complexity of having a signalling server . You simply must use your signalling channel to exchange the following information I m using the C naming but other languages should have similar names but following the language conventions : .. . .. . 1 . One peer s offer generated via callback OnLinkOfferAnswer once you call Conference.Link is sent to the other peer . To call Conference.Link you need to know the peer ID of who you re connecting to so may need your signalling server to send this data to us in my usage I actually connected to an intermediate server for recording and thus could use a hardcoded server peer ID . 2 . That peer s answer generated via callback OnLinkOfferAnswer once you register the offer with Conference.ReceiveOfferAnswer is sent to the first peer and registered the same way . 3 . Both peers will generate ICE candidates with the OnLinkCandidate callback multiple times which must be sent to the other peer and registered with Conference.ReceiveCandidate . Note that this all occurs asynchronously so the ICE candidates could be generated before the answer is received . That is fine as IceLink will internally manage them . You must keep track of which peer this is meant for the offer answer and candidates are peer-specific . It s entirely up to your signalling library XMPP here to generate some kind of unique peer ID so that you can identify users you could do it yourself if your signalling library does not . The data that gets exchanged is JSON but you shouldn t have to modify it in the typical usage . The OfferAnswer and Candidate objects have FromJson and ToJson methods to handle the conversion .", "Question : I wanted to send out data to a specific client on a channel using the Ajax Push mechanism .

I want to send it out to say client 7 on Channel 1 . In Ajax Push I know I can send out the Push to all subscribers of Channel 1 .

Comment : Alright . Have never heard of it so can t really answer it . But usually these push solutions usually got some concept to push data to specific users . I guess if WebSync server doesn t then you could create separate channels for every user and then just push to that channel Comment : Well I don t want to add like 1000 channels for 1000 users . I thought of that but its just a waste . So even if i have just 10 channels and 10 clients in each I wanted to know if you can do a push to just one specific client . Comment : Don t think it would be a problem from a performance point of view . But maybe from a convenient point of view. . depending on their api .. . Answer : You really do what do have a separate channel for each user . Channels are very cheap with WebSync even if there was a built-in way to send data to a specific user it would be implemented exactly in that manner . Having 1000 channels is not a big deal recently I had a discussion with one user who had something like 10 000 channels per connected client which is pretty extreme to be fair but was working without a hitch . Simply create a channel such as user username and use that to push to that user specifically and you ll be good to go .", "Question : I have created an iPhone application using phoneGap and i have implemented the Websync functionality using javascript all functionality are working fine but my problem is that When Iphone goes to sleep-mode than the app is still open and when you wakeup the phone websync doesnt work anymore . .. . Answer : iOS and other mobile-devices don t allow JavaScript to run in the background when the device is sleeping . Battery life would suffer tremendously if it did .

I have a solution which uses merge replication to do one-way data sync with the client application of the solution . The server uses SQL Server 2008 the client SQL Server 2008 Express and initiates the pull subscription using RMO . The request goes through Web Sync . All is fine when the IIS and the DB is on the same server - the problem occurs when the IIS is on a standalone web server . From the error logs it seems certain SQL components are required on the web server to make this work - but I haven t been able to find which ones .

Answer : A short note for my own question for the time being . All elements : Polymer.Base .. . .. . Polymer uses Base s addFeature method to extend the Base prototype which is the prototype of all Polymer elements side note : addFeature method itself uses Base s extend method internally . This is the deepest level for extending Polymer Elements . Specific element type : element constructor object as well as Behaviors .. . .. . Behaviors are shared between all elements of a specific type . They are applied in element registration time . And of course methods in the constructor object also goes to element type s proto . Specific to an element instance : everything else .. . .. . Other methods defined from element creation onward are specific to that element instance . Also if you use Polymer.Base.create tag obj all the properties and methods in the obj will be applied to the created element using in keyword i.e . no accessors . Hence that obj could be shared between different element instances depending on the context . Conclusion .. . .. . The standard way Polymer creators wanted us to share methods and a lot more between different element types is using Behaviors . However if you have a feature that all or most elements use extending Polymer.Base is a good option .", "Question : I ve got a newly created polymer-starter-kit 1.3 to be exact .

What I would like to happen is for the added div to have its inner HTML equal to the value returned from method computedValue . The value cannot be assigned at the time of div creation as in the real situation it would depend on the realtime context . .. . Answer : It appears that for now Polymer 1.0 does not support dynamic imperative bindings . Here https : github.com Polymer polymer issues 1778 and here https : github.com Polymer polymer issues 1796 are the relevant discussions . The information from the above links suggests a reliable albeit limited approach to creation of dynamic-content with bindings by means of using dom-bind template elements . The limitation is due to bindings working strictly with locally defined methods and properties for the dom-bind instance being created . Here is an example where domBind is created imperatively with properties tapCount tapMessage and method tapMe . The latter is used as on-tap event handler for the added to the domBind element div . A similar to my question is posted here http : stackoverflow.com questions 30836412 polymer-1-0-injectboundhtml-alternative which helped me to get a better appreciation for the scope of the problem especially with the reference to Polymer 0.5 injectBoundHTML . .. . .. . Of course external methods and properties can still be accessed : .. . .. . Then by binding locally defined externalMethod one can bind things from the external scope .

How can I solve this issue Comment : Do you have workflow attached Is it possible it s not approved yet Also if you browse to the item in the Content Editor do your changes show up there as you d expect .. . Answer : While saving an item in Page Editor Sitecore saves all the field renderers which are displayed on the page so if you set the Item property of a FieldRenderer1 to Product Example Test Sitecore Item Page Editor know which item should be saved . The problem with publishing is that you enqueue the current item in the publishing queue but this item has no link-to the Product Example Test Sitecore Item in any of its properties cause you re setting the Item property of the field renderer dynamically in the code . The option would be to add another button to Page Editor next to Edit Related Item button and create a command that will Publish Related Item . The complete description how to add such a command can be found in the answer Sitecore page-editor - how to extend page-editor item editing panel http : stackoverflow.com a 18351584 157833 Comment : Spot on this is exactly what I wanted to know .", "Question : Need to add publish feature to the page-editor item editing section .

For point 4 if we can type Mandarin or Japanese any reason why we need automated translator Comment : Also regrading translator did you say they use the Google translator API Comment : If your content authors type Mandarin and Japanese content manually you don t need any automated translator . In terms of automated translators there is a module called Sitecore Language Translator which uses Google API to translate the content but it will never be a proper translation . There are also paid solutions like Clay Tablet - your content is translated by proper human translators .", "Question : We use Sitecore CMS for our website at the moment and are considering adding the Sitecore DMS in the near future . A colleague of mine insists that it is absolutely necessary to have our page-editor along with the cloning functionality enabled and working for us to be able to use the DMS . I m familiar with their CMS but not the DMS so I wanted to know -- is it absolutely necessary .. . Answer : Cloning functionality is mostly used for Multivariant MV Tests . As it suggests in the Marketing Operations Cookbook http : sdn.sitecore.net upload sitecore6 65 marketing operations cookbook sc65-usletter.pdf : .. . .. . When you use the Page Editor to set up an MV test you can use existing content clone content or create new content items to use as test variable variations . This means that you do not need to ask a developer to help you to create special content to use in your MV tests . In the Page Editor one can create combination tests . These tests allow you to test more than one control on the same page . This is multivariant testing . More information on MV Tests like cloning items to use as test variables or creating combination tests is also given in the Marketing Operations Cookbook http : sdn.sitecore.net upload sitecore6 65 marketing operations cookbook sc65-usletter.pdf . More over also remember that you can also create MV Test in Content Editor but note the below as suggested by Sitecore .. . .. . If you create an MV test using the Content Editor you do not have access to the same statistics on Engagement Values generated when you test these controls . We recommend that if possible you create all MV tests using the Page Editor . So if one your goals for using Sitecore DMS is MV tests I would suggest you do use cloning . Hope this helps in deciding the way forward .

Any thoughts welcome.. . .. . .. . Erwin .. . Answer : The problem you describe is not new to Sitecore 7 . You would have the same problem in Sitecore 6 you would just have to go through the additional effort of keeping your content organized . This is a fundamental limitation of Sitecore s presentation framework . I have worked around similar problems before by using Presentation Inversion of Control http : www.awareweb.com awareblog inversioncontrol1 category e697cc2030034ea39ef65be033a5c530 topic bcab6d57624347eda723110cd70bb48d . I should probably write an update for that since the rules engine approach no longer works .. . .. . I believe that Cognifide is doing something similar with the Composites in their Zen Garden http : www.sitecore.net Community Best-Practice-Blogs Przemyslaw-Taront Posts 2012 08 The-Zen-of-Sitecore-Part-1.aspx but instead of using a dummy layout they use an empty layout so any item can be opened as a page . Then they added a custom experience button which navigates to that non-page content item within the page-editor . Note that this is speculation based on a brief demo that I saw . Thomas Eldblom also blogged years ago about what he called Composite Layouts http : pentialized.dk tag composite-layout . It s similar to PIoC but puts the presentation settings on a special rendering type . In short there are ways to achieve what you want but they all involve custom development and will require extra attention to maintain a smooth page-editor experience .", "Question : I m in the page-editor and I m seeing JSON where editor controls should be .. . .. . commands : click : chrome : field : editcontrol command : webedit : chooseimage header : Choose Image icon : icon SoftwareV2 16x16 photo landscape.png.aspx isDivider : false tooltip : Choose an image type : null click : chrome : field : editcontrol command : webedit : editimage header : Properties icon : icon SoftwareV2 16x16 palette preferences.png.aspx isDivider : false tooltip : Modify image appearance type : null click : chrome : common : edititem command : webedit : open header : Edit the related item icon : temp IconCache SoftwareV2 16x16 cubes blue.png isDivider : false tooltip : Edit this item in the Content Editor . type : common contextItemUri : sitecore : master 2D90E98C-1360-4EBA-855E-3B321B053376 lang en ver 1 custom : displayName : Logo expandedDisplayName : null .. . .. .

The error occurs when I am in the Sitecore Page Editor mode . First of all I m not able to select each of the content items on the page and I m not really sure why that is the case . But I may not be 100 clear on what the requirements are for configuring a content item for an A B test in Sitecore . In the Sitecore Page Editor when I highlight a content item and click the red boxes icon to bring up the Test the Component dialog the Test Content Item : just says Not set . When I then click the 3 dots to attempt to browse to a content item I get a pop-up error message that simply says an error occurred . What are the requirements for a content item to be defined as a test variation in this version of Sitecore Or is there something else that needs to be done before attempting to configure the test variations in the Sitecore Page Editor Comment : Just to check is the component you are testing driven by a datasource Comment : Currently no and that is one of the things that I wasn t sure about whether or not it was a requirement for this to work . In addition to having a datasource it seems like the content item that you are defining the test variations for needs to be a sublayout that is attached to a placeholder . Is that correct .. . Answer : In order to use A B Multivariate testing your Sitecore website solution needs to support the idea of page components . Each component is a sublayout that pulls its content from a datasource item . The test is essentially just swapping the datasource for the sublayout so you can test different content much like you would setup DMS personalization . If your content is not structured into page components you cannot execute the tests . There are several companies out there that will audit your build to determine your solution s DMS-readiness and you can probably get them to fix up your build to support DMS as well . If you will be doing it yourself here are the basic steps : .. . .. . 1 . Split up your page layout into sublayouts . At the very least the portion that you want to test should be in its own sublayout . 2 . Create new component templates for your content that will be displayed in these sublayouts . This will be the data for your datasource . 3 . Create new content items from your new component templates to represent the data variations you want to try . 4 . Update the code for your sublayouts to access the Datasource property of the sublayout to find the content Item instead of using Sitecore.Context.Item .. . 5 . Using Page Editor configure your page component datasource to pull from one of your new component content items . Comment : That makes sense . I didn t realize that the components that you re creating test variations for had to be sublayouts with data sources - before you go in and configure the test variants .", "Question : I could not find a single official document on setting up and using multilingual on Sitecore SDN .

I don t think there is an option to do that but I might be wrong Comment : @MarekMusielak Yes sorry misunderstood you . But you are right you have to go up the tree and add it as a child . .. . Answer : In order to be able to use the Insert Page button the item you are inserting under must have Presentation defined . It doesn t need to have components added and I ve worked round this before by simply define a blank layout and setting it on those items . Maybe create yourself a new template inheriting from Folder and then set Layout on that . But this is a workaround at best . You can only Insert Page below the current page you are on so you would essentially have to navigate to a blank page in order to create the sibling . From what you have stated it sounds like you may want to re-think where your Insert Options have been set and your content structure i.e . why would you want create another Home item Creating so will require set-up of another site and related config .

Answer : Judging from your reply to my comment you need to think of the following : How is my field value being rendered onto a page .. . .. . If you are always using 1 control to do this then you just need to ensure that this control has 2 different rendering modes depending on the Context.PageMode .. . .. .

Following the instructions at http : vertx.io blog vert-x3-says-hello-to-npm-users I used npm to install vert.x . I can run a simple hello-world app but running our existing app is proving to be a little challenging . All the vert.x docs I ve found talk about writing new apps not porting existing code . Oh and the same code base needs to continue running on existing nodejs systems . The trouble that I m seeing is that vert.x won t load nodejs native modules correctly . For example Vert.x choked on this require : .. . .. . After a little searching I found the vert.x equivalent : .. . .. . Perhaps we could create an shim abstraction-layer to wrap the differences . I did a quick one for the file system API and it seems to load correctly . It does seem like writing an entire abstraction-layer will be a fair bit of work . But it seems like it would solve the compatibility issue for APIs used within our source . The real trouble is how to intercept all the require statements in the node-modules directories . Those modules are also going to be requiring lots of other native APIs like the file-system . This seems like a problem that others may have encountered and solved already . Better not to re-invent the wheel . I could roll my own solution . I don t really want to sed replace the node module source except as a last resort . The only other alternative I have thought of is creating a directory of abstractions an inserting that directory name at the head of the NODE PATH . This solution seems like it might work but as I mentioned I m a vert.x noob so I cannot forsee what kinds of pitfalls lie along that approach . Does vert.x support a shim layer for running nodejs applications .. . Answer : Short version TLDR : .. . .. . You can t Long version : .. . .. . Vert.x is not a Node.JS replacement or runtime . Although there are quite similarities and common design choices such as support for CommonJS modules and support for NPM the native libraries are not present . All I O operations in Vert.x are done using Vert.x API and they do not always relate to the Node counter parts . Also you should be aware that the JavaScript language version is not the same either for example Node relies on V8 which nowadays is quite close to fully support ECMA2015 or ES6 for short Vert.x as a framework running on the JVM relies on Nashorn the JavaScript runtime from the JDK itself which is still on ES5 . The idea of supporting NPM in Vert.x was not to emulate Node but to allow the usage of many of its modules that do not depend on node native modules . For that reason there is a warning on the documentation http : vertx.io docs vertx-core js . But I guess it is not clear . There are some ways to get most out of NPM and Vert.x one option is to go 100 ES6 and use a transpiler such as Babel https : babeljs.io to transpile back to ES5 which will run fine both with Node and Vert.x until the moment you use a native module . If you must to use Node say that you already have an application built on node and the port is not worth in terms of resouces time etc then I d suggest to look into the tcp eventbus bridge https : github.com vert-x3 vertx-tcp-eventbus-bridge . This bridge will allow your existing application to produce and consume messages of an existing cluster of vert.x applications . Comment : Paulo I appreciate your answer . This confirms what I was thinking . I did miss that warning in the docs . The challenge we re facing is that we cannot run V8 because . . . well long story . So moving to vert.x will require a significant amount of rework but it s better than rewriting from scratch .

Vert.x provides a runtime environment to process events . It provides eventloops which you can use to process your events . Check out this presentation which explains the core concepts of vert.x very well : https : www.youtube.com watch v qL5BGHPXrac . Vert.x is implemented in java and when you start vertx like this then you start the jvm which executes vertx core which then executes your javascript . The problem is that I think you have no access to the java execution environment from your javascript file .

Answer : Vert.x 2 does not support cluster-wide shared data . However Vert.x 3 does expose an asynchronous API that wraps the underlying Hazelcast cluster manager . For Vert.x 2 though you can use the Hazelcast instance directly in your worker verticles . Just use Hazelcast s static-methods to get the Vert.x Hazelcast instance : .. . .. . Note that you should only access the Hazelcast API directly in this way from within a worker verticle . The Hazelcast API is blocking so it will block the event-loop if used in a normal verticle .", "Question : I have a situation where I call an external API A and use its response to feed to request of API B and call it and afterwards return the response to caller of API A .

I checked about executeBlocking method of vert.x and also tried of using blocking queue but unable to achieve what I am intended to do . Can someone please direct me to correct way of doing it.Thanks in advance . EDIT : Just to explain the exact scenario .. . .. . I am using vert.x framework with Java . Now what happens during execution is flow comes to STEP 1 initiate API A call . Goes to STEP 2 without waiting for respFromApiA and makes call to API B which fails eventually because respFromApiA is NULL . And finally flow goes to STEP 3 and return from here . without waiting for outcomes of API A and API B . If we see the print order it will be something like this .. . .. . What I am trying to achieve I hope I am able to make clear this time . Please let me know if you need further inputs . Comment : Why don t you do both calls in method sequentially Comment : I guess you are doing non-blocking calls . They most likely return their responses in a callback I don t know vert.x sorry . So you need to find either a possibility to tell vert.x that you want those calls to be blocking and return the result or you need to use the callbacks . Comment : Maybe if you showed more of code real code then someone with experience in vert.x could help .. . .. . Answer : Vert.x is highly asynchronous . So most operations will infect return immediately but their results will be available to the Handler at a later point in time . So far so good . If I understand you correctly than you need to call B in the Handler of A . In this case A needs to be finished and the result would be available before you call B : .. . .. . But what you are trying is to make something asynchronous synchron . If you try to make a asynchronous result available in the main program flow that wouldn t work . Call API A can t really return a result because it s calculated asynchronously . The result is only available for the Handler of Call API A see my example above . Same for Call API B so you can t return the result-of Call API B . The caller of your class would also need to call your class with a Handler . Now some additional information . In your case you have the problem that multiple asynchronous results depend on each other . Vert.x provides a much more convenient way to handle asynchronous results the so called Futures . A Future sometimes called Promise but in the Java world they are called Future is a placeholder for results of asynchronous calls . Read about them in the documentation http : vertx.io docs vertx-core java async coordination . With a Future you can do something like this : .. . .. . So instead of trying to return the asynchronous result-of B in a synchronous way you should return a Future so the callee of your class could register for the asynchronous result-of both A and B . I hope this helps . Edit : Future as return-value .. . .. . Lets say you want to wrap callA with so you can work with a Future . You could do it this way : .. . .. . The Caller of this function can use the Future like this : .. . .. . It also possible to compose multiple Future if you want to do them concurrently but they don t dependent on each other : .. . .. . If you work in a asynchronous environment like Vert.x most of time you work with a soon-to-be-available-result aka Future . And in the Handler of a Future you often do another asynchronous call . You wrap a Future with a Future like the example of callB in callA s Handler . How would you return the asynchronous result-of a Future as an HTTP Response Like this : Comment : Thanks @Alexvetter for answering me . I agree with the logic of calling API B in handler of API A . This I tried already and it works.Mistake I am doing is trying to return response to caller of class synchronously which should be handled via a handler . Just to clear one point at the end I have to return the response of API B to the caller.You said about using future object . So we just put return-type as Future and return the future object to caller to get the response Comment : Exactly you should play a little bit with Future and its method setHandler . Comment : Because Vert.x is highly asynchronous your application will hand Futures around and compose them as you need .

It is using Github as Authorisation server.I am curious to know how to implement Authorisation server in vert.x i know spring-security provides this feature i.e Oauth2Server and OAuth2Client . .. . Answer : Vert.x OAuth2 is just a OAuth2Client there is no server implementation so you cannot get it from the Vert.x Project itself . Vert.x OAuth2 supports the following flows : .. . .. . Authorization Code Flow for apps with servers that can store persistent information . Password Credentials Flow when previous flow can t be used or during development .

Is there documentation about using Scala with vert.x 3 Where is it .. . Answer : There is no official Scala for Vert.x 3 yet . You should follow the GitHub repository vertx-lang-scala https : github.com vert-x3 vertx-lang-scala . At work we are using the Vert.x 3 Java API with Scala . It works as it should . But native Scala support which makes use of Scala language features would be great . Drop some lines in favor on the Vert.x mailing list .

BootStrap.groovy Websockets : .. . .. . javascript Comment : I m not sure if its a grails issue or vertx issue . .. . Answer : Vert.x use the JVM to create a so called multi-reactor pattern that is a reactor pattern modified to perform better . As far as I understood is not true that each verticle has its own thread : the fact is that each verticle is always served by the same event-loop but more verticles can be binded with the same event-loop and there can be multiple event loops . An event-loop is basically a thread so few threads should serve many verticles . I didn t use vert.x in embedded mode and I don t know if the main concept change but you should perform much better instantiating many verticles for the job .. . .. . Regards Carlo", "Question : I ve implemented a REST API with Vert.x and I want to monitor its threads . I package the app as a fat-jar and I m using JVisualVM and JProfiler for monitoring . When I launch it from the IDE Intellij I can see everything but when I launch it with java -jar fatjar I can only see memory consumption . I enabled JMX from the application thinking JVisualVM uses JMX to get the metrix but it didn t help . What should I do to enable JVisualVM access to threads and CPU Thanks in advance : .. . Answer : With jvisualVM you should be able to see all vert.x threads however you should be aware that Vert.x is a reactive framework so you will not see a thread being spawn for each request . One thread per CPU core will handle all load . What are you trying to monitor exactly would be interesting to know since it could be that you re just looking on the wrong place.. .", "Question : I want to program a FTP Client with Vert.x in Java - I found only examples for FTPClients in JavaScript .

Use handler or blockingHandler .. . Answer : It all depends on the kind of code you re writing inside the handler . Starting from your second questions first all template-engine handlers implement a asynchronous API although loading the template itself is blocking but only done once due to the cache . In that case you should use : .. . .. . Going back to the first question if your couchbase client API is blocking meaning that it is not responsive it does block until you get a response back from the server then in that case you must use blockingHandler or else you block the event-loop and by extension block the whole application . If however you re using couchbase async API then you should use the handler variant . For an example on how to use the async API see this blog post http : blog.couchbase.com 2015 december couchbase-java-sdk-writing-vertx-verticle .", "Question : I m developing in Vert.x based on Netty and Hazelcast and I m trying to share data between two server instances eache of those instances in different machines on the same lan .

I ve read many documents off Vert.x and Hazelcast but I haven t had results yet . I don t know how to force vert.x to load hazelcast xml-configuration files . Thanks in advance .. . Answer : There are options for sharing data among vertx instances on different machines .. . .. . Option 1 . .. . .. . You could use the Vert.x ClusterManager http : vertx.io api java org vertx java core spi cluster ClusterManager.html and it s maps : .. . .. . That map is backed by a Hazelcast IMap and is distributed . This assumes you re running vertx with the -cluster parameter and have configured clustering .

You can get access to Hazelcast once vertx is started in clustered mode : Comment : Went with option 1 and wrapped it in a class . If we want to update vertx in the future where this breaks we ve got one-stop shopping .

Answer : As has been pointed out the data sharing objects bundled in Vert.x don t support sharing data across multiple Vert.x instances . In order to do that you would have to do either : .. . .. . 1 . Use a normal shared database . 2 . Set up a Verticle which manages the SharedMap instances and publishes and listens for updates to and from the rest of the cluster . 3 . Design your application so you don t need to share data in this way .", "Question : I am using vertx-mysql-postgresql-client-3.3.0 and vertx-sql-common-3.3.0 I initially thought of using Batch operation to insert multiple statements but looks like this http : vertx.io docs vertx-sql-common java batch operations is not implemented in the vertx-mysql-postgres-client . The code that handles post data to db is : .. . .. . The AsyncResult handler code : .. . .. . This one doesn t work and gives Thread Blocked error after inserting first . Any idea how I can make the multiple inserts work .. . Answer : Vert.x is an asynchronous framework however the code is using a synchronous construct that will not work . There is a while-loop until a variable is greater than 0 . but the update to the control variable is updated on a async handler which means that it won t be called inside the loop . Knowing this the loop will run forever until the JVM thread scheduler will stop it to run other thread which will eventually update the the control var . Now that the scheduler has stopped the thread you will also be notified by Vert.x that you blocked the event-loop which means you should revise your code . I d suggest either to concatenate the SQL statement in on big sql statement and execute at once or use a for-loop . Note that the for-loop is also not 100 safe . Say that you re inserting 1M rows you can also easily use more than 2s of CPU time and you ll get the warning again . The good solution would be an async loop or look to RX for example . Comment : Using for-loop also I get the same thread already running issue . Will a query like INSERT INTO Targets name id language VALUES taglineParams result - work", "Question : null .. .

You can find more details in vertx core document : vertx.io docs vertx-core java blocking code http : vertx.io docs vertx-core java blocking code .. . Answer : It seems that you are calling your rabbitmq client from the event-loop . It is usually forbidden because you are blocking the event-loop . You should use your rabbitmq client from vertx.executeBlocking to deal with a remote service like rabbitmq . You code will be executed with a thread from the worker pool . From vert.x 3.3 you can monitor more closely the worker pool . I would recommend to try the rabbitmq-client for Vert.x : http : vertx.io docs vertx-rabbitmq-client java as it manages the executeBlocking stuff for you .", "Question : Is it possible to integrate Objectify in a Vert.x application Let me give you some context . I have a REST API exposed by Vert.x 3.3.0 that interacts with Google Cloud Datastore using gcloud-java library . Everything works fine but I want to use a higher level API to make all that code easier to read and more maintainable . Objectify setup https : github.com objectify objectify wiki Setup indicates that .. . .. . Objectify requires a filter to clean up any thread-local transaction contexts and pending asynchronous operations that remain at the end of a request . The thing is I have no web.xml and Objectify seems to need a servlet filter to work . .. . Answer : It is my understanding that Objectify is specifically designed for Google App Engine . It works well within applications that are deployed to GAE . I did not have any luck using it outside of GAE not even in Compute Engine . Since you mentioned that you are using the gcloud-java library to access the Cloud Datastore you might want to check out Catatumbo https : github.com sai-pullabhotla catatumbo an Object Mapping and Persistence Framework that is built on top of gcloud-java . Catatumbo is similar to JPA . Catatumbo is an open-source project distributed under the Apache v2 license .

Is anyone aware of a clean way to do this I want to preserve the two projects as they are because I like using the webpack-dev-server for development of the UI and it generally feels cleaner to have them separated . .. . Answer : You could create a gradle task that before that depends on the jar task so it runs before it executes webpack compile into the resources directory .

This only happens in Mobile Safari . .. . Answer : I haven t been able to reproduce the problem you describe here . Regardless of what I do the z-index value is retained throughout all transforms . I m testing using Chromium Google Chrome . The third argument of the translate3d function manipulates the z-axis of the element . The concept is similar to but not exactly the same as the z-index.. . Elements with a lower z-axis are under elements with a higher value . I know you tried values of the third argument to match your intended z-index but the problem is that the z-axis doesn t seem to change during CSS3 animation . In the following example the hovered element should be on top but element a stays on top . If I add a z-index to both the regular selector and the : hover selector it seems to work and allow the hovered element to be top-most . Although it s not exactly what you were looking for this behavior provides a solution . You just need to use translate3d and z-index to set the order for the initial rendering .

The effect still happens . Comment : cssdeck.com labs full ornh3chv http : cssdeck.com labs full ornh3chv .. . Answer : The blurred fonts are caused by a weird webkit issue invloving -webkit-backface-visibility . This took me forever to figure out and I haven t seen it anywhere else on the web yet . I now add -webkit-backface-visibility : hidden to the body of my site as a CSS reset style . Watch it sharpen the fonts on your entire site its amazing . You re transformations are not 3d so this wont affect anything anyway but if you do decide to do 3d transformations somewhere else on your site just add back -webkit-backface-visibility : visible to the specific element . Should also fix the flickering too . Comment : Don t do this . What this is effectively doing is activating -webkit-font-smoothing : antialiased on your entire page which is actually a step back from the default -webkit-font-smoothing : subpixel-rendering . See Please Stop Fixing Font Smoothing http : www.usabilitypost.com 2012 11 05 stop-fixing-font-smoothing for more background . Comment : I see what you re saying but the visible result is unbelievably better . Mobile devices do not use sub-pixel rendering anyway so this doesnt affect them . This also fixes the flashing which is a huge issue and in my opinion something that you simply can t live with . Can you suggest a better way to stop both the flashing and render the fonts correctly Furthermore you can explicitly define -webkit-font-smoothing : subpixel-rendering Comment : Perhaps you should post a new question with those points so that they can be answered separately I think they re off-topic for the comments here . Comment : Perhaps but I believe that users who now visit this question will also want to know the answer . You didn t offer any sort of solution to the problem just said that my solution was incorrect . Moreover the case for sub-pixel rendering is still a matter of opinion . Many browsers and OS do funky things with sub-pixel rendering and can hurt the design . Sub-pixel rendering is also automatically turned off during css transformations causing all sorts of issues .

So changing the rotation point to the right left edges of the panels solved it . Weird but for now it works . I have a simple HTML5 CSS3 page with four panels . These panels use -webkit-transform to form them into a nice arrangement . On : hover I use -webkit-transform to bring the panel up to the foreground . The code is below . What happens is that the : hover action is unreliable . If I swipe the mouse over the panels it s common to stop moving the mouse with it hovering over a panel but the panel is still in its original position . Specifically swiping from left to right the leftmost two panels appear to work fine but the rightmost two don t scale up until the mouse is halfway across the panel . What would cause this EDIT : Quick follow-up it appears that links placed in the transformed elements will only be clickable on the leftmost for the two left panels or rightmost for the two right panels halves of the elements . In other words the click zone is only active for the closer half of the element . First the HTML minimal example : .. . .. . And the CSS : .. . Answer : I had the same issue with only the top 50 of the link being hoverable and clickable while the entire element was still visible . I fixed this by adding translateZ 1px to my -webkit-transform . This brings the entire element in front of the Z-axis and makes it completely hoverable and clickable . There is however a 1px zoom with the translateZ but it s unnoticeable .

Does anybody know how to tell Safari to re-render a div with the new scale Comment : How do you know the browser is not re-rendering the contents of the DIV Does it contain an image com .. . Answer : I m trying to do the same thing . I think what s happening here is that Safari is just scaling pixels . That is it does all its normal browser rendering and then scales the pixels of the result . Example : Place a relatively high quality image say 1000x1000 pixels in a small div 200x200 pixels and set the image to 100 width and height . When you 3D transform the div to scale 5 times the result will be blurry in Safari and crisp in Chrome . Use a 2D transform and the image will appear crisp in both . A workaround is to convert to a 2D transform after you are done with the 3D .

Answer : You can use the Bind method on the WebGrid to tell the grid to use server-side paging . grdv.Bind myData rowCount 10000 autoSortAndPage False .. . .. .

This is an okay solution but I would like a more clean look because the webgrid default has a small padding in the table cell so the div won t expand completely to the size of the cell either . Is there a way to edit the td in any way I know I can change the background and other style attributes using jquery or javascript but I don t like the idea of having doing duplicate work to first build the table on the server then on the client-side iterate over it again conditionally changing the colors when this should have been completed with the first iteration . .. . Answer : With the help of Golda s response and here http : code.stylenet.ca mvc3-dynamically-set-row-background-color-in-a-mvc-webgrid I was able to create an elegant solution . This solution uses JavaScript JQuery as it doesn t seem possible to do it without it but using to me a cleaner solution than what I had came across . What I did in the model class type for List was add a property that refers to itself and returns an instance cast to its interface like so : .. . .. . I did this because the webGrid seems to only allow access to the properties and not methods regardless of access level . Then in that same model I have a method which will conditionally attach markup for a hidden input field to the data string and return it as an MvcHtmlString object : .. . .. . And in the markup partial view I make my grid.Column call : .. . .. . Then I create the JavaScript function s : .. . .. . The window.onload is needed to point to the SetFeaturedRow function to set the row colors at page load the function name SetFeaturedRow is stored in the ajaxUpdateCallback property through the webgrid constructor arguments : new WebGrid Model .... . ajaxUpdateCallback : SetFeaturedRow Or it can be set through the WebGrid reference ref.ajaxUpdateCallback SetFeatureRow .. . .. . This will be used during any ajax call the WebGrid class will make . So for example if there are multiple pages to the webgrid each selection is an ajax call and the row colors will need to be re-updated .

Any ideas are appreciated . Here s my code .. . .. . .. . .. . Answer : This is a terrible hack but it allowed me to get on with my day . I think the way to do this correctly is to write an Html Helper that allows you to pass in the footer row . I m a little disappointed the WebGrid doesn t have a footer row built-in . Only make sure you match the number of columns in your hand built table row . Notice there is no table start tag. . The whole idea is to hijack the created html at the table close and add a row .

I have to define a div with ID and refer the div s id in the ajaxUpdateContainerId attribute of WebGrid control that will allow WebGrid to update data asynchronously using Ajax .

The current version of the WebGrid has little to no documentation incomplete implemtation etc .

Answer : You can download the source code of ASP.NET MVC 3 http : aspnet.codeplex.com releases view 58781 and inside you have the source of WebGrid . Once you unzip you will find it inside the webpages src System.Web.Helpers WebGrid WebGrid.cs file .

In this case as again I think his major concern is to get the code and maybe debug then it s enough open for the author s needs .

Answer : I have an apache2 web server that handles reverse proxy for Rails3 app running on another machine . The setup works except URLs generated within the webapp aren t getting rewritten by my configuration for mod-proxy html . The Reverse Proxy Scenario http : www.apachetutor.org admin reverseproxies is exactly what I m trying to do so I ve followed the tutorial as completely as I know how . I ve applied or tried two answers supplied here http : stackoverflow.com questions 3479061 i-cant-seem-to-get-mod-proxy-html-working-at-all-no-debug-output-no-errors and here on stackoverflow to no effect . According to the Reverse Proxy Scenario you want a number of modules loaded . All those instructions are in my httpd.conf file and when I examine the output from .. . .. . all the expected modules show in amongst the listing . My external web server doing the reverse proxy is at www.ourdomain.org and the Rails app is internally available at apphost.local the server is Mac OS X Server 10.6 the rails app server is Mac OS X 10.6 . What s working right now is access to the webapp via the reverse proxy as : .. . .. . http : www.ourdomain.org apphost railsappname controllername action .. . .. . But none of the javascript files css files or other assets get loaded and links internal to the web app come out missing the apphost portion of the URL as-if my rewrite rule is configured incorrectly so of course I ve focused on that and can t seem to get anything to be added or deleted in the process of passing the html in from the apphost and out through the Apache server . Here s what my Apache directives look like : .. . .. . After every change I make to httpd.conf I religiously check apachectl -t just to be sane . I m definitely not an Apache expert but all the directives that follow mine seem to not overrule what I m doing here . But then nothing that I try seems to alter the URLs I see in my browser after hitting the Apache server with a request for my web app . Even if you can t tell what I ve done incorrectly I d welcome ideas on how to get Apache to help see what it s working on and doing to the html coming from my web app .

What do you get if you just paste the URL to the image into the location bar in your browser Adding a semi-colon to the end of the final statement in a block makes no difference .

Comment : Is this an internal behind-the-firewall application Comment : Yes it is internal Comment : Is there anything else I can add to improve this question .. . Answer : I d be curious about a solution that uses OpenID as a backend of sorts for this.. . I wasn t seeing anything that would hook into ActiveDirectory directly when I googled quickly . However it could be pretty painless to implement over plain HTTP S you d be an OpenID provider that checked credentials against your local AD . In a best case scenario you might be able to just add a couple classes to your app and be off and running -- no web server modules required . There is a lot of open-source code out there for either side of this so if nothing else it s worth taking a look . If you exposed the backend to the users i.e . gave them OpenID URLs you d have the added benefit of them being able to log in to more than just your internal sites using these credentials . Example : Stack Overflow . As an aside I d be against making it so that Internet Explorer is required . I m not sure if that is the goal from the way you wrote the question but depending on your IT environment I d expect people who use Firefox or Safari or Opera or .. . to be less than enthusiastic . You re not developing against IE first are you That s been painful whenever I ve done so . This is not to say that you couldn t use this feature of IE just that it shouldn t be the only option . The link you posted stated that NTLM worked with more than IE but since I don t have any experience with it it s hard to judge how well that would work . Comment : All browsers support NTLM authentication . IE is no longer a requirement .", "Question : On my server I have both a tomcat7 and an apache2 installed . I stopped the tomcat7 service and want to listen to with apache2 on port 80 also tried for test with 8082 and port 443 and tested also with 442 . Before I stopped tomcat7 I tried it with 8082 and I could establish webside call and got the webside . But after I stopped tomcat7 and want to listen with apache2 to the ports 80 and 443 I could not establish a webside call also not again if i tried it again with 8082 and 442 . A netstat tulpe returned the following : .. . .. . My ports.conf : .. . .. . and the 000-default.conf .. . .. . a service status-all returned : .. . .. . The error-log shows : .. . .. .

But not on a webbrowser on an other machine . Why not BTW : A lsof -i returned noting . Why not Server version : Ubuntu 14.04.4 LTS .. . Answer : You have provided all the right troubleshooting tools thank you One recommendation : omit the e argument from the netstat - for this type of troubleshooting you want the numerical port numbers not the translations into human-readable form . The p argument also does nothing if you are not root but it doesn t hurt either . The key to solving your problem is the netstat output . Your netstat output shows that Apache is listening on port 8082 but not on port 442 . In your configuration you also have not provided any SSL configuration the 000-default.conf does not mention any SSL configuration options so most likely it is simply not configured . So that explains the port 442 issue . The second thing the netstat output shows is that Apache is listening on port 8082 but only on one particular IP address . Since your wget succeeds that is probably the correct one it is just a unusual issue and could potentially cause issues down the road if your network configuration changes . The last problem you mention is that you cannot reach the server from any other system . On that none of your config files give a clue but usually this type of problem is that you did not open port 8082 in your firewall . One more aside : instead of using wget for testing I d initially use telnet . Because telnet is lower level there are fewer moving parts that could interfere with your test . That s just a general tip though - in this case wget did give you the information you needed . Comment : Thank you very much for your answer I already added the SSL config file .

I ve found some links talking about Kerberos and Apache modules . http : www.onlamp.com pub a onlamp 2003 09 11 kerberos.html page last https : metacpan.org pod Apache2 : : AuthenNTLM .. . .. . Since I m running on Windows it s proven to be non-trivial to get Perl or Apache modules installed . But doesn t PHP already have access to HTTP headers I found this but it doesn t do any authentication it just shows that PHP can read the NTLM headers . http : siphon9.net loune 2007 10 simple-lightweight-ntlm-in-php .. . .. . I d like to be able to have my users just point to the application and have them automatically authenticated . Has anyone had any experience with this or gotten it to work at all UPDATE Since originally posting this question we ve changed setups to nginx and php-fcgi still running on windows . Apache2 and php-cgi on windows is probably one of the slowest setups you could configure on windows . It s looking like Apache might still be needed it works with php-fcgi but I would prefer a nginx solution . I also still don t understand and would love to be educated why HTTP server plugins are necessary and we can t have a PHP web server agnostic solution . Comment : Is this an internal behind-the-firewall application Comment : Yes it is internal Comment : Is there anything else I can add to improve this question .. . Answer : For IIS PHP FCGI You need to send out an unauthorized header : .. . .. . You can then get at the username with : .. . .. . I then make sure the winuser is in my database of allowed users . Be SURE and test this under a non-privileged account . When I first installed this I tested it and it worked fine but later when a standard non-server-admin user tried it this failed . Turns out some of the temporary directories need to have permissions changed for guest users . I can t recall the exact settings . Comment : Does this work for non iis servers Comment : I don t manage any non-iis servers so I don t know ." ] }

Looking for clarification on how Spring XD taps work for metrics . I need to know if one stream can be tapped multiple times so that each message through the primary stream will be sent to each of the active defined taps . The scenario is a stream with a rabbit source that has processing before delivering to a sink such as mongo . This stream is tapped to an alternate sink . We also want to create multiple metrics on this stream including an aggregate counter and a couple of field value counters that will keep metrics on total messages and message by type looking a different fields in the source message which os on JSON . The documentation is unclear on if each tap gets a copy of the message . In testing the first tap is getting all messages but none of the field value or aggregate counters seem to be getting data . .. . Answer : Yes A stream can have multiple taps . Here is an example https : github.com spring-projects spring-xd-samples tree master analytics-dashboard . Internally XD uses the message bus to bind to a pub-sub resource https : github.com spring-projects spring-xd blob master spring-xd-dirt src main java org springframework xd dirt plugins AbstractMessageBusBinderPlugin.java L304 transport dependent . For example using Rabbit MQ transport a Fanout exchange is created https : github.com spring-projects spring-xd blob master spring-xd-messagebus-rabbit src main java org springframework xd dirt integration rabbit RabbitMessageBus.java L710 for each potential tap point in a stream . Binding a queue to that exchange is performed lazily i.e . when the tap stream is created . You should see the corresponding exchanges and queue bindings for each tap in the Rabbit admin console . I m not sure why you are not seeing messages in all taps . Keep in mind that taps should always be deployed after the target stream is created but before the target stream is deployed any data in the stream before the tap is deployed will not be consumed by the tap .", "Question : I am newbie to Spring XD .

Thanks a lot for your support . Cheers Happy Architecting .. . Pratik Comment : Yes you are right it does includes Batch Integration and Boot .

Comment : What do you mean by in-memory processing in Hadoop You want a HDFS to run in memory .. . Answer : SpringXD is the data ingestion layer . If you want to do you want to use SpringXD to sink your data into Gemfire Redis or JBDC and do your in memory processing there SpringXD gives you tools out of the box to do so .

Is there another location where I need to specify that the default gets overwritten .. . Answer : AFAIK if you want to use a different prefix in Spring Batch you would have to create the batch repository tables manually . If you look at the scripts that are used for creating the tables they have the BATCH prefix -- https : github.com spring-projects spring-batch blob master spring-batch-core src main resources org springframework batch core schema-oracle10g.sql .. . .. .

It is really hard to plan for any significant deployment in the future without complete developer documentation .. . .. . We have recently assembled all the important documentation fragments and are now available at Spring Cloud Data Flow s individual server implementations eg : Spring Cloud Data Flow s Cloud Foundry Server Reference Guide http : docs.spring.io spring-cloud-dataflow-server-cloudfoundry docs current-SNAPSHOT reference htmlsingle index . For convenience we have also added pointers to all various implementations and the corresponding reference guides to the project page http : cloud.spring.io spring-cloud-dataflow spring-cloud-data-flow-server-implementations . We have plans to add project pages for individual server implementations too . Since Spring Cloud Data Flow draws off Spring XD heavily would using Spring XD documentation till we get this complete help in any way Though the underlying goals vision is largely same fundamentally Spring Cloud Data Flow is an entire rewrite and the orchestration of streams and tasks batch pipelines requires a runtime platform like Cloud Foundry .

We came across Spring batch XD cloud data flow . From the quick review of documentation on http : cloud.spring.io spring-cloud-dataflow we could not assess whether Spring cloud data flow also has all the batch-processing features that spring-batch would offer . For example here is what SPring batch documentation http : projects.spring.io spring-batch says : Spring Batch provides reusable functions that are essential in processing large volumes of records including logging tracing transaction management job processing statistics job restart skip and resource management . If someone has any idea about the batch-processing capabilities in spring-cloud data flow could you please post here . Many thanks .. . Answer : Please review Spring Cloud Task http : cloud.spring.io spring-cloud-task project . This project offers the framework and programming model to develop short-lived microservice applications . At a high-level a Task may be any process that does not run indefinitely including Spring Batch jobs . This gives you the flexibility to develop Spring Batch jobs using all its core capabilities and you can run them as standalone Spring Boot applications . There are some samples here https : github.com spring-cloud spring-cloud-task tree master spring-cloud-task-samples . Spring Cloud Data Flow builds upon Spring Cloud Task to provide orchestration capability for batch data pipelines . A wide range of options including Shell DSL Admin UI and Flo UI https : network.pivotal.io products p-flo-for-spring-cloud-data-flow are available to orchestrate batch workloads . You can use these utility Task applications https : github.com spring-cloud spring-cloud-task tree master spring-cloud-task-samples in Spring Cloud Data Flow and this list is growing .

Any help on this specific queries would be highly appreciated . .. . Answer : Can I leverage the same environment setup which I used for spring-xd Spring Cloud Data Flow SCDF relies on spring-cloud-deployer https : github.com spring-cloud utf8 E2 9C 93 query deployer SPI and there are implementations for Cloud Foundry Apache YARN Apache Mesos and Kubernetes . Given that you re already having an Hadoop cluster with YARN in use you could provision the YARN implementation https : github.com spring-cloud spring-cloud-dataflow-server-yarn of the SCDF-server . is it using embedded drivers for stream processing Not clear what you mean by this . If you re referring to jdbc-drivers specifically when using jdbc as a sink application we do embed OSS-friendly drivers yes . If it is using embedded drivers can I use it to deploy in a clustered environment with the same infrastructure leveraged for spring-xd Perhaps answer to 1 covers this . You could leverage the same infrastructure and provision YARN SCDF-server using the Ambari plugin https : github.com spring-cloud spring-cloud-dataflow-server-yarn blob master spring-cloud-dataflow-server-yarn-docs src main asciidoc getting-started.adoc deploying-on-ambari . Is there any specific wrappers built for Apache Spark We have Spark as a client https : github.com spring-cloud spring-cloud-task-app-starters tree master spring-cloud-starter-task-spark-client and cluster https : github.com spring-cloud spring-cloud-task-app-starters tree master spring-cloud-starter-task-spark-cluster applications . You can register https : github.com spring-cloud spring-cloud-task blob master spring-cloud-task-docs src main asciidoc stream.adoc spring-cloud-data-flow them in SCDF to build task batch pipelines . Comment : Thanks for your convincing answer I meant embedded drivers as spark-driver which is mavenized along with spring-boot which can be deployed in a runtime container . Kindly confirm if this option is feasible and would be great if you could send me some references . Comment : I ve created some instructions for running a small Spark test app on YARN .

For some reason the main spring MBean exporter is trying to export the router normally the IntegrationMBeanExporter disables that when present . EDIT .. . .. . Here s a work-around.. . Create this file and put it under xd config as .. . .. . xd config META-INF spring-xd plugins jmx mbean-exporters.xml .. . This replaces the standard file and makes the stream name part of the MBean domain so the MBean names are unique . The only difference to the standard file is the addition of the default-domain to the context mbean exporter . We still need to address the underlying issue as to why the normal exporter does not have that bean suppressed but this should get you going . Comment : I added a workaround .

Thank you so much for your time . regards .. . .. . Alice .. . Answer : The MessageBus SPI is very specific for XD intra-module commmunication it s not designed for arbitrary application-level messaging . That said XD and its message bus implementations uses the Spring Integration project http : projects.spring.io spring-integration extensively . That project provides the abstraction you need . You can send to a message-channel either using a MessagingGateway or a MessagingTemplate and downstream of that channel you can wire in any kind of channel adapter rabbit amqp redis etc . So your item processor is decoupled from the actual technology that receives the message . Take a look at the Spring Integration reference manual there s a link on the project page . Comment : Thanks Gary I tried this one out . Needless to say ran into a lot of newbie issues . I updated my question with my findings . Thanks again for your time . Comment : RabbitMQ is not a JMS provider it s a completely different protocol . Pivotal does have a commercial JMS client for rabbitmq but if you want to talk native rabbitmq amqp then you need to change the int-jms : outbound-gateway to an int-amqp : outbound-gateway . See the spring-integration documentation http : docs.spring.io spring-integration reference html . Comment : Thanks Gary that helped . I added the following rabbitmq configuration and added the named exchange to the outbound gateway . This should make all the messages appear in RabbitMQ . I dont see it yet probably because I am running as a test . I will try to run as the actual application . rabbit : topic-exchange name myExchange rabbit : bindings .. . rabbit : bindings rabbit : topic-exchange .. . amqp : outbound-gateway request-channel importExchangesChannel reply-channel importExchangesChannel exchange-name myExchange routing-key foo.bar amqp-template amqpTemplate Comment : You need a rabbit : admin to declare the queues etc or set them up manually in the broker .

Answer : As far as I understand Visual Web Developer http : www.microsoft.com express vwd VWD is simply a free version of the Visual Studio http : www.microsoft.com visualstudio en-us default.mspx components necessary to develop web based solutions . Here is a list of features missing from VWD http : blogs.msdn.com mikhailarkhipov archive 2006 06 26 647516.aspx that you get in a Professional edition of Visual Studio 2008 VS2008 . In short VWD Express 2005 .. . .. . 1 . is Not Extensibile with other add-ons or third party tools .. . .. . 2 . Only supports Web site projects 2005 . You cannot add a Class Library project or a Web Controls Library project to the solution . .. . UPDATED - VWD 2008 SP1 also allows Web Application and Class Library Projects in the solution . .. . 1 . Lacks the ability to combine Source Code Control .. . .. . 2 . has no Accessibility checker .. . .. . 3 . Lacks ability for automatic generation of resources for localization .. . .. . 4 . Cannot attach debugger to a process .. . .. . 5 . has no Native code debugging .. . .. . The obvious advantage of VWD over VS2008 is that it is free and if you can work smart with it given the missing features it may be the more pragmatic option for you . If those are features that you can t live without VS2008 may be a wise investment - you also get all of the features missing from other Express products Visual Basic 2008 Visual C 2008 etc . Take a look at MSDN s comparison chart for Visual Studio 2005 http : msdn.microsoft.com en-us vstudio aa700921.aspx . I can t find 2008 s but would suspect it to be very similar . Comment : All of point 2 is now wrong . As of Visual Web Developer 2008 SP1 you can now have Web Application Projects and indeed raw class-library projects in the solution - this is so you can build projects using ASP.NET MVC in it . Comment : I ve also previously successfully created Web Controls library projects in Visual C Express 2005 and used the resultant dll in VWD - you need to declare the libaray in the web.config of the website to get VWD to recognise it .

Answer : It looks like the Visual Web Developer team solved the problem by adding HTML5 support themselves : http : blogs.msdn.com webdevtools archive 2009 11 18 html-5-intellisense-and-validation-schema-for-visual-studio-2008-and-visual-web-developer.aspx .. . .. .

Answer : I think you also lack the ability to publish a site without visual-studio you can certainly run a website but it won t build the binaries for release with web developer you have to publish the source to iis . Comment : Again wrong as far as VWD 2008 SP1 is concerned - this has the ability to create Web Applications and thus a compiled binary . This was added to support ASP.NET MVC development on the platform . Comment : Again . . Regardless that is fantastic the last time I used an VWD was 05 and obviously you weren t able to compile .

SQL Server Compact 3.5 and .. . 3 . SQL Server Database File . BUT if you use Visual Web Developer 2008 Express you can connect to a regular SQL Server Oracle ODBC etc . For people developing command-line or other C apps that need to talk to a SQL Server database do you really need to build your LINQ Data Access code with one IDE Visual Web Developer and your program in another Visual C It s not a hard workaround but it seems weird . If Microsoft wanted to force you to upgrade to Visual Studio to connect to SQL Server why would they include that feature in one of their free IDEs but not the other I feel like I might be missing something like how to do it all in Visual C . Comment : This is a terrific question . The whole SQL Server mess is very frustrating from even choosing which version to use to actually developing with it to deploying it . This question addresses one of the major hassles along the way . Comment : How is this closed as not constructive It has tons of upvotes and views and lots of people seem to find it helpful . SO is closing questions way too easily nowadays . .. . Answer : Workaround : .. . .. . 1 . Open your solution in Visual Web Developer Express . It will not load some of the projects in the solution but it is ok . .. . 2 . Make a new connection in Database Explorer to the required database from SQL Server . 3 . Add a new class-library project . 4 . Add a LINQ to SQL Classes item and link it to your database . 5 . Close the solution . 6 . Open the solution in Visual C Express .

I really would appreciate any help . thanks . .. . Answer : For Visual Studio 2010 I always used inetd which is a port forwarding tool . Since Visual Studio 2012 I have this problem as well . The problem is that only localhost calls are allowed in the development server even proxy calls don t work unless you change the request headers . I have made some modifications to an existing simple proxy server which I found on GitHub . It changes the IP address in the request url to localhost . Download the code here http : opensource.oxyva.nl simple-development-proxy . .. . .. . I found a better solution .

It is very limited but you may wish to have it just for those purposes . You might want to use free SQL Server Management Studio Express to do that .", "Question : I cannot uninstall Visual Web Developer 2010 Beta 2 .

Either way I think the documentation is a bit confusing I agree with you there . Comment : After many failed attempts I managed to get the data into analytics .

When I make a request to Google Analytics is there a way to replace the existing value of the metric instead of adding new value to it Let s say that the current value of that metric is cm1 100 .

Answer : The Google Analytics Measurement protocol https : developers.google.com analytics devguides collection protocol v1 hl en is used for inserting data into Google Analytics the javascript snipet that websites use also uses the measurement-protocol as does the IOS and Android SDKs . Once data is inserted into Google Analytics there is no way to change the data that was inserted . For example when you are using ecommerce and a user adds an item to there shopping car the item is inserted into Google Analytics if the user then removes it you need to credit the users record that is done by adding the same item again only with a - value This doesn t remove either item it just nulls them out kind of . Think of the measurement-protocol as inserting a row into a database you insert an event with custom metric 1 having a value of 500 then in 5 minutes you insert another row with custom metric 1 having a value of 200 you now have two rows one where custom metric is 500 and another where its 200 .

If my message is ignored how do I know what I did wrong Trial and error For example the parameter reference says that Application Name an Name is an optional parameter for web properties https : developers.google.com analytics devguides collection protocol v1 parameters an . However if I add this my requests Google starts ignoring them completely . Why More importantly how can I find out why on my own Is there a log the Google Analytics portal https : www.google.com analytics web somewhere .. . Answer : You can debug Measurement Protocol hits with the Measurement Protocol Hit Builder https : ga-dev-tools.appspot.com hit-builder . This tool works by sending hits to the Measurement Protocol Validation Server https : developers.google.com analytics devguides collection protocol v1 validating-hits behind the scenes to validate the hits and report error messages . The document linked here goes into more detail on how to send hits to this service manually if you wanted . Comment : The hit builder says Hit is valid . Yet Google Analytics ignores it . Here s the actual message slightly sanitized : v 1 tid UA-XXXXXXXX-1 cid 561d0e8f-d99e-4542-8208-bad5a4c03f10 dh hostname.com an testapp t pageview dp 2ftestpage dt testpage . If I remove an testapp GA processes it . If I leave it in it doesn t . Supposedly this is a perfectly valid optional parameter https : developers.google.com analytics devguides collection protocol v1 parameters an . Comment : Are you sending these hits to an app view or a web view Comment : Web view . The docs say that Application Name is required for an app view but optional for a web view https : developers.google.com analytics devguides collection protocol v1 parameters an . My particular web app is Silverlight app and I find the Application Name parameter useful but I can work around not using it . However the larger question is how one gets insight to why Google Analytics is ignoring a message . Comment : To answer your larger question if GA is ignoring a hit that the Measurement Protocol Validation Server is saying is valid that s a bug and I m looking into it . The MPVS is how you re supposed to be able to find these things out on your own . That s the whole point of the tool .

This is explained quite step-by-step here : developers.google.com analytics devguides collection https : developers.google.com analytics devguides collection analyticsjs events Comment : I know about JS methods as i mentioned above but there have to be a way to send the same information using server-side . Comment : @DaImTo - Feel free to do that but OP asked for a step-by-step . And while I would tell him if he s going the wrong way it requires for me to know that he is in fact going to wrong way .. . Answer : Hello Analytics API : PHP quickstart for service-accounts https : developers.google.com analytics devguides reporting core v3 quickstart service-php is not going to help you at all . That code uses the core reporting API the core reporting API is for requesting data from Google Analytics not sending data to Google Analytics . To send data to Google Analytics we use the Measurement Protocol https : developers.google.com analytics devguides collection protocol v1 . The measurement-protocol is used to send information to Google analytics the JS snippet you posted also uses the measurement-protocol . You can use the measurement-protocol from any language that supports HTTP post or Http Get . That being said there is no PHP specific library for sending information to Google analytics you are going to have to format your post yourself . A tip would be to use Validating hits https : developers.google.com analytics devguides collection protocol v1 validating-hits to check it before you send it to Google while you are developing this . It will probably look something like this Comment : Thank you I ve seen that but thought that there are some methods in mentioned API for sending . So do i need just POST or GET URL and that s it But what to do with authorisation Or that should be sent only from registered server Comment : Nope measurement-protocol is the only way to send tracking data to Google analytics . The other APIs are just for requesting data and account administration . Comment : It seems like everyone can take my URL and do something weird with my stats Comment : well not your url but yes you can view the source of someone s website get there Google Analytics tracking id and send garbage data to there Google Analytics account using the Measurement protocol .

Comment : @EikePierstorff I added an example of the kind of calls to wget I am using . .. . Answer : Directly from the documentation Google Analytics Collection Limits and Quotas https : developers.google.com analytics devguides collection protocol v1 limits-quotas .. . .. . These limits apply to the Web Property Property Tracking ID . .. . 10 million hits per month per property .. . .. . Measurement protocol .. . .. . Universal Analytics Enabled .. . .. . This applies to analytics.js Android iOS SDK and the Measurement Protocol . .. . 200 000 hits per user per day 500 hits per session not including ecommerce item and transaction hit types . If you go over either of these limits additional hits will not be processed for that session day respectively . These limits apply to Premium as well . Now I agree it doesn t specifically state the per second it rate for measurement-protocol but the above one dumped Measurement in with analytics.js so I think we can assume its .. . .. . analytics.js : .. . .. . Each analytics.js tracker object starts with 20 hits that are replenished at a rate of 2 hit per second . Applies to all hits except for ecommerce item or transaction . But just to make sure I am sending an email off to the development team they should make it more clear where the per second rate of the measurement-protocol lies . I will repost here when I hear from them .. . .. . Response from Google .. . .. . The Measurement Protocol does not do any kind of rate-limiting or quota-ing by IP address or tracking ID or anything like that . However most of the client libraries do rate limit in some form or another . .. . As Linda points out in her answer there are various limits and quotas imposed by the back end but those are done at processing time not collection time . Conclusion .. . .. . There is no limit to sending data through the measurement-protocol . But when the data is processed limit may be applied . I think they may be referring to the max 2 million hits a month . It seams it s the libraries that apply limits on how fast you can send data not the measurement-protocol directly . Comment : Looking forward to gleefully handing over the bounty in return for a definitive statement from Google on this matter . Comment : Actually the documentation says When the count is 0 the maximum limit has been reached and no new requests are sent which suggests that the send quota the docs are referring to is enforced at the client-side .

The two choices are Web Site and Mobile Application and both seem to need configuration beyond what is suggested as the requirements in the Measurement Protocol page . Comment : The measurement-protocol doesn t care if its universal or application Google analytics its up to you to send the correct data for the different types of analytics accounts . Comment : I m still trying to figure this out but I did create both Mobile and Web properties . Only the Web Property type will accept events and page views from Measurement Protocol API .

I was bit buy this last year . This might help daimto.com monitoring-quota-usage-for-google-apis http : www.daimto.com monitoring-quota-usage-for-google-apis .. . Answer : The Measurement Protocol is property-agnostic . If you go to this hit-builder site https : ga-dev-tools.appspot.com hit-builder you will notice that it doesn t ask what type of property you are using ie . UA vs classic GA . It just needs to know the property ID type of hit client ID and version number . Comment : I agree that it should be property-agnostic but my testing results do not agree with this theory . I created both property types and submitted hits validated with hit builder to both property types . Only the Web Property logged the information . The Mobile Property did not . Comment : Can you show the hits you were sending to both the web and mobile app properties Comment : I m accepting this answer but it does not match my results -- the Measurement Protocol is property-agnostic but the API isn t . Hit Builder does ask what type of property you are using it queries it from the property you selected .

Comment : Try and figure out what all the parameters in the second url mean measurement-protocol is nicely documented . Comment : @EikePierstorff : Is documentation the only reason .. . Answer : The measurement-protocol is now the backbone for data collection for Universal Analytics for all versions web mobile etc . Unlike the gif-method it is well documented and it can be called from every device programming language that can send http requests it will still return a transparent gif though . The main reason for using the measurement-protocol is that everything else is deprecated and Google has announced that support for older tracking methods will be dropped . It looks like your second example uses an older version of the Analytics tracking code current versions send their calls to the https : www.google-analytics.com collect endpoint . You should not invest a lot of effort in developing solutions based on deprecated technology especially if it offers no advantages over the current versions .", "Question : In our project we stored all users event data in our database for over one year but it s not indexed . now we are going to use google-analytics to store our analytics and analyze the report using google-analytics dashboard . but before start using google-analytics i would like to emigrate all old statics about 2 million events to google-analytics . for this matter i should use Measurement Protocol https : developers.google.com analytics devguides collection protocol v1 reference and it s limit allow me to transfer 2 million hits with no problem . but i didn t succeed to know how to set the time of the event .

I m not sure one can say much more about that . Comment : @EikePierstorff thank you for your comment but can you think about any work around maybe by using custom dimensions .. . Answer : You are correct you can use the measurement-protocol to send events data directly to google-analytics . I don t see any problem in sending 2 million events . However its not possible to set the event time longer then four hours ago . Queue time is used to set the time that the event occurred as you can see it cant be more then four hours ago and I have found that if you do set it to four hours ago its a bit fuzzy if the data is correct or not . This feature is probably most use in mobile-devices where they may go off line for a short time you can store the data then send it all once the device is online again . So the dates will be the date that you sent the event to Google Analytics you cant back date the data to more then four hours ago . So I am not sure how much use the data will be to you when it is all inserted . Comment : Thank you for your answer but do you have any work around maybe by using custom dimensions Comment : wont matter you still wont be able to get any useful analytics out of 2 million rows inserted today with a custom dimension of some date a year ago . Everything is going to be analyzed as-if it was all the hits happened today .

Answer : There is no way to do this but you can make it easier on yourself . Unfortunately there is no way to add remove or otherwise edit Google Analytics hit data retrospectively except to delete all of it . You also cannot copy or move it between accounts or download it all . You are not the first to have to come to terms with this . In this situation we recommend to our clients that they run their new and old systems in parallel-for a testing period usually 6 months or a year before switching off one of them .

Answer : The Maven convention is that the compiled classes are put into target classes . Unless you have a very good reason to do it differently it is better and much less painful to stick to the convention .

I m using a library Circumflex ORM http : circumflex.ru projects orm index.html that lets you define schemas as follows : .. . .. . This works because of an implicit view that s in-scope within Record : .. . .. . I m trying to introduce a new extension method alongside TEXT etc . called BYTEA . So I know I need my own implicit helper class : .. . .. . Now I need an implicit in scope whenever I m defining new records but I don t want to write an import statement every time : .. . .. . And I don t want to introduce this implicit to any other scopes besides the record definitions . So one idea is to subclass Record or introduce a mixin then define my schema records by extending MyRecord instead of Record or always mixing in MyMixin . I first tried : .. . .. . This produces : .. . .. . So instead I tried : .. . .. . But then I get these two issues when defining a record : .. . .. . The errors are : .. . .. . After more fiddling I surprised myself by finding something that worked : .. . .. . I m curious to understand what just happened here as well as perhaps some more examples to help me wrap my head around things better so that I don t feel like I m always fiddling-until-it-works . Apologies for the question title - not sure it makes any sense . .. . Answer : Your first error is the simpler one and easily solved by your final solution . The self-type R in the declaration .. . .. . forces every descendant of Record to ensure that it will be an R too it does not make it an R the descendant will have to do something to be an R . In practice that means that in class X extends Record PK R R must be an ancestor of X and as there is also R : Record PK R it should be X most of the time but as we will see at the end this may not be the case . This constraint disappears in MyRecord hence your first error . Your final solution states the constraint again and that s the end of it . .. . .. . Your second version is more complicated . I ll start with the second error . first some elements from the Circumflex API not stated above . Record has an abstract def relation : Relation PK R .. . Table K R extends Relation K R .. . .. . You define relation in the class User as the object User which is a Table Int User hence a Relation Int User . However your class User is a MyRecord Int User but that means it is a Record Int MyRecord Int User not a Record Int User . The R of Record the one that matters here is MyRecord Int User not User . relation must thus be Relation Int MyRecord Int User . A Relation Int User is not a Relation Int MyRecord Int User even when User is a MyRecord Int User . In general if B is an A C B is not a C A except if class C states so by being declared C +X rather than C X . hence the message about Relation being invariant no + and suggesting a +R so that it would be covariant in R . I m really less sure about the error in DefinitionHelper . It seems related to the R being MyRecord Int User again . If you explicitly state that as the generic parameter R doing .. . .. . it should work I did it on an example quite close to your code but not actually using circumflex . Why the compiler does not infer that I do not know . Anyway the fact that your User is not a Record Int User but Record Int MyRecord Int User is bound to cause problems . The actual solution is much simpler ." ] }

Comment : If you go through some openstack tutorials and read some of the respective books I think you will find your answer . Comment : @Athafoud maybe is because i ve read but i did not understand that i am doing a question here . .. . Answer : Openstack follows Service Oriented Architecture . It uses WSGI and django framework . So every component exposes few REST APIs . You can find these APIs in api folder . For example https : github.com openstack-cinder tree master cinder api . Internally these API calls make call to manager . manager.py is the file which handles main logic . https : github.com openstack-cinder blob master cinder volume manager.py . It calls underlying driver classes and co-ordinate with other openstack services through their APIs . Comment : i asked to explain how the components interact example how glance use the image what cinder does with volumes what is the role of swift . Comment : Glance stores image swift is similar to S3 is Amazon web-services . They interact through APIs provided . If you have any specific question please ask . Comment : thank you for the answer . What is the role of cinder in my example it just creates the volumes where i can attach the instances of nova or what does it save the images in phisical disks please help me know the difference between swift role and cinder role and i ll put accept answer on the answer u gave me . Thank you for your availability . Comment : Cinder is a block storage provision service . So using cinder you can allocated drives for your computing resources . It can store varied range of data in block memory . Consider it as hard disk of your machine . While swift is object storage system . It can storage large objects such as system images and other object structures . Glance is image management service . So it will help to manage images which user can use to boot their compute resources . Comment : Ok i understood . So i use cinder for example for applications where an hard drive is needed for example a db management or something like this instead of swift that allows to save objects like media and so on.Thank you very much.Very kind .", "Question : null .. .

Answer : Using Kubernetes on bare metal and trying to figure out how to mount a external bloc storage volume from an OpenStack cloud provider .

Compute Nova .. . Storage Cinder .. . Network Neutron .. . .. . But to me all Compute Nova instances are VMs . VMs with file systems . VMs that need to be networked and ultimately receive their network connections from a physical switch in an actual data center somewhere . So to have Storage and Network nodes that provide file system storage and network connections at first blush seems unnecessary . Couldn t all nodes be Compute Nova nodes Why do I need Cinder Storage nodes for file system space Each Nova node will have its own file system yes Why do I need Neutron Network nodes for networking connections Won t my Nova nodes receive their network connection from the physical switch in our data center Obviously I m missing a major piece of the puzzle here so I ask : what is it that I m missing .. . Answer : But to me all Compute Nova instances are VMs . Strictly speaking this is incorrect . Nova has a number of component parts . Simply put there is a API component which exposes the service interface and one or more compute components that talk to VM hypervisors . So a single nova compute node can support multiple VMs . The idea is that you scale up Openstack by running more servers capable of hosting virtual machines . For more details on how Nova works I suggest reading the developer documentation : .. . .. . http : docs.openstack.org developer nova devref architecture.html .. . .. . I also recommend first learning the interaction between Keystone Glance and Nova . Hopefully you ll begin to understand how each additional component adds more services to your cloud . Comment : Thanks @Mark O Connor +1 - I appreciate the correction there but by Compute Nova instances what I really meant to say was Nova-managed instances which is more in alignment with what you re saying here . More importantly I m still looking to understand why we need Cinder and Neutron in the first place . Think about it : if Nova creates a VM that VM should get its networking from a physical switch and it will have its own file system for storing data . So why do we need Neutron and Cinder That was my question : - Comment : @smeeb Cinder is used to managing block storage volumes you don t have to have them but can be useful for persisting data . Similarly Neutron provides more advanced networking services beyond DHCP .

We re doing some testing and for some reason our IT team thinks is something related to HAproxy Swift stopped working .

Is there any framework available to develop this I have no idea about how to read this file-format . I tried to parse a sample file with .epub extension using NSXML Parser but that fails . .. . Answer : The EPUB format brings together a bunch of different specifications formats : .. . .. . one to say what the content of the book should look like a subset of XHTML 1.1 + CSS .. . one to define a manifest that lists all of the files that make up that content OPF which is an XML file .. . one to define how everything is packaged up OEBPS : a zip file of everything in the manifest plus a few extra files .. . .. . The specs look a bit daunting but actually once you ve got the basics unzipping parsing XML down it s not particularly difficult or complex . You ll need to work out how to download the EPUB to unzip it somewhere to parse the manifest and then to display the relevant content . Some pointers if you re just starting out : .. . .. . parse xml http : www.tbxml.co.uk .. . unzip http : code.google.com p ziparchive .. . .. . To display content just use a UIWebView for now . Here s a high level step by step for your code : .. . .. . 1 create a view with a UIWebView .. . .. . 2 download the EPUB file .. . .. . 3 unzip it to a subdirectory in your app s documents folder using the zip library linked above .. . .. . 4 parse the XML file at META-INF container.xml if this file doesn t exist the EPUB is invalid using TBXML linked above .. . .. . 5 In this XML find the first rootfile with media-type application oebps-package+xml . This is the OPF file for the book . 6 parse the OPF file also XML .. . .. . 7 now you need to know what the first chapter of the book is . a each item in the manifest element has an id and an href . Store these in an NSDictionary where the key is the id and the object is the href . b Look at the first itemref in the spine . It has an idref attribute which corresponds to one of the ids in a . Look up that id in the NSDictionary and you ll get an href . c this is the the file of the first chapter to show the user . Work out what the full path is hint : it s wherever you unzipped the zip file to in 3 plus the base directory of the OPF file in 6 .. . .. . 8 create an NSURL using fileURLWithPath : where the path is the full path from 7c . Load this request using the UIWebView you created in 1 . You ll need to implement forward backward buttons or swipes or something so that users can move from one chapter to another . Use the spine to work out which file to show next - the itemrefs in the XML are in the order they should appear to the reader .

ZIP is a pretty simple format and it should be fairly easy to create libraries that give you input streams for the various files in the archive that read directly from the archive on the fly if you don t already have such libraries .

Answer : On top of Ole s answer that s a pretty good how-to guide it s definitely worth reading the specification for the Open Container Format OCF http : www.idpf.org doc library epub OCF 2.0.1 draft.doc - sorry it s a word file . It s the formal specification for the for zip structure used . In brief you parse the file by .. . .. . 1 . Checking it s plausibly valid by looking for the text mimetype starting at byte 30 and the text application epub+zip starting at byte 38 . 2 . Extracting the file META-INF container.xml from the zip .. . 3 . Parsing that file and extracting the value of the full-path attribute of the first rootfile element in it . 4 . Load the referenced file the full-path attribute is a URL relative to the root of zip file .. . 5 . Parse that file . It contains all the metadata required to reference all the other content mostly XHTML CSS images . Particularly you want to read the contents of the spine element which will list all content files in reading order . If you want to do it right you should probably also handle DTBook http : www.daisy.org daisy-standard content as well . If you want to do this right you need to read and understand the Open Packaging Format OPF http : www.idpf.org doc library epub OPF 2.0.1 draft.htm and Open Publication Structure OPS http : www.idpf.org doc library epub OPS 2.0.1 draft.htm specifications as well .

I ve developed an open-source project to do that http : scribaebookmake.sourceforge.net .. . Answer : I haven t seen a java epub toolchain however I have been having good success with Sigil . If the goal is to make an epub I d give Sigil a go . Before I used it I was rolling my epubs by hand with the automation of an ant build.xml . If the goal is to make a java based epub toolchain then it shouldn t be terribly hard depending on how much validation and pipelining you wish to do . Personally I d start with writing an epub viewer . As far as the PDF parts go I just embed XHTML . Haven t had a need for embedding PDF yet . As far as epub validation goes if all the xml is valid and there s no dangling links prior to zipping you re going to have a valid epub . Comment : I have to create a server tool that make automatically an ePub file starting from PDF and XHTML . So I thought about Java API . I think Sigil cannot be helping to do this...or not Comment : @robob No Sigil won t help with a Java facing tool . It is more of an editor than a toolkit .", "Question : This question already has an answer here : .. . .. . Reading ePub format questions 1388467 reading-epub-format 6 answers .. . .. .

It s just little more than a bunch of zipped HTML files . .. . Answer : Epub is just an archive like zip or tar . If you want to create an epub file with php from scratch you have to create separate html-files and a few xml-files with the correct information .

Answer : A simple way consists in unzipping the EPUB file into a temporary directory and then loading the XHTML files from there . In this way the relative links to image files CSS files etc . present in each XHTML file will be resolved automatically by the WebView . An example of this technique is here : https : github.com pettarin epub3reader .. . .. . Of course you can avoid unzipping the entire EPUB file and just read one XHTML file into memory RAM but if you do so you have to patch the XHTML source to be injected into the WebView and or manually manage the extraction of the images CSS etc . files referenced from the current XHTML . If you aim at simple EPUB files the just unzip in a tmp directory approach is much easier .", "Question : I m relatively new to ePub format but if I understand well to make programmatically an ePub starting from XHTML or PDF content could mean : .. . .. . choose HTML or XHTML content and validate them with an XHTML validator or clean them with Tydy .. . choose PDF file to insert in the ePub .. . create the XML manifest or XML packing files and TOC file .. . zip the whole files in a .epub file .. . validate the ePub I saw something in Google code .. . .. .

Comment : which listener is set to port 81 .. . Answer : If GlassFish and Oracle Database are installed in the same system it results in port conflict as both of them use port 8080 . Here is the procedure to change port-number of GlassFish so that you can run GlassFish at a different port-number from Oracle to avoid the port conflict . 1 . Find out the folder where GlassFish is installed . If you installed GlassFish along with NetBeans you can find out the folder where GlassFish is installed by using the following procedure . Select Services window by using Window - Services in NetBeans IDE .. . .. . Expand Servers node and select GlassFish Domain .. . .. . Right click and select Properties option from popup menu . On the right of Domains Folder you can see the folder where GlassFish is installed . For example : .. . C : netbeans6.8 glassfish-v3 glassfish domains . You can also see the other details regarding Glassfish such as port-number in the same window . 2 . Go to the folder where Glassfish in installed . 3 . Go into config folder which is as follows : c : netbeans6.8 glassfish-3 glassfish domains domain1 config .. . .. . 4 . Open domain.xml using any text-editor . 5 . Look for 8080 and change it to some other port-number that doesn t conflict with other port numbers . I generally change it to 9999 . 6 . Save domain.xml . 7 . Now you need to remove GlassFish from NetBeans and add it again so that NetBeans IDE understands the new port-number . For this do the following .. . .. . In Servers window of NetBeans remove GlassFish by using RemoveServer button after selecting GlassFish server . Click on AddServer and select GlassFish V2 or GlassFish V3 and click on Next . Select the Installation Location of GlassFish and click on Next . Accept defaults and click on Finish . .. . .. . .. . 8 . Restart GlassFish if it was already running .

Incidentally poking around under home dir .netbeans version config J2EE InstalledServers you ll see another .nbattrs file and because I have two app servers installed locally I see fileobject name instance for Tomcat and fileobject name instance 1 for GlassFish .

Answer : No . When you host your service you are free to define one or more endpoints for the service s operations in the configuration of the service . However each of these operations will be exposed on all the defined endpoints . The exception to this is that certain transport bindings do not support certain types of operations .

Answer : Your problem in this case is not T in ServiceContract but T1 used as DataContract . You can use T in service contract if you replace T with specific type during service contract implementation . For data contracts operation parameters and return types you can t use T at all . You always have to specify concrete type . Your service contract can be rewritten with usage of ServiceKnownTypeAttribute so that T1 is replaced with FI CusipMaster and ServiceKnownType specifies all possible classes derived from FI CusipMaster .

Never given it much thought to be honest . Interface feels more logical to me for a service contract . I usually implement it in an SI FL layer though . Comment : Interface can be shared between the parties in the dedicated assembly . Having interface you can also use Dependency Injection pattern to inject current implementation of the service . Comment : The link you have shared in your question is best answer . Best Practices . Comment : from the link which i shared is not very clear that why people go for interface for service contract . .. . Answer : As you have demonstrated - you don t need to define an interface for a service contract to get it working . However arguable in doing so your class is violating the principle of Single Responsibility http : en.wikipedia.org wiki Single responsibility principle granted this is officially an OO principle - but in my opinion it is one of those universal principles that seems to be a good idea everywhere . The service contract acts as the contract duh between the publisher of the service and the clients that consume it . As such once you have clients consuming it you need to be very careful about any changes you make - especially if the clients may be third parties over which you have no control . In accordance with the Single Responsiblity Principle defining an interface that represents the contract allows you let this interface have responsibility for the public API separating it from the implementation . This implementation is a relies of the fact that all clients connect to the same instance : .. . .. . This implementation give you a new instance of the service for every call to it : .. . .. . The advantage of the interface is that I can mess around with the implementation as much as I like including it s instancing mode concurrency it s behaviour under client sessions namespace the name of the class etc . and not have to worry that I m potentially breaking any clients . Agreed - there are ways to maintain backwards compatibility even if you define the service contract to be the class - but it s far more error prone and you are more likely to forget something . Separating the public API and it s implementation leads to cleaner code and a smaller risk of developers making mistakes . Comment : whatever reason here u highlighted those are valid point but not mandatory . many people say if we make our service a service contract instead of interface then our business logic will be expose to client but really do not understand how it will be possible at because when client will create proxy then proxy will never expose implementation detail at client-side . so tell me what kind of problem will occur surely regarding service implementation . thanks Comment : i search goole lot to know the what actual problem may occur at the point of service security many people say if we make our service a service contract instead of interface then our business logic will be expose to client but really do not understand how it will be possible . do u have any idea about it Comment : As I say in the first sentence - it certainly is not mandatory for everything to work . I d be amazed if not using an interface resulted in some security breach . The points they may be getting at is that by using the class as the contract you may inadvertently expose some implementation detail like the name of the class which may hint at how you could launch an attack on the service . For example if my class was called SqlLogger then someone may try to launch a SQL injection attack . I believe you could get round this anyway by specifying a name on the ServcieContract attribute . Comment : Although not mandatory from a functional point of view I would argue that from a maintainability and risk perspective you should be using an interface . It leads to more concise and easier to understand code which in turn reduces the risks of errors leaking in to a live environment . This can only be a good thing - and in some organisations this would be enough to ensure it becomes a mandatory policy .. .", "Question : This is a question I got asked in an interview . When you create a WCF service you get two files IService.cs and Service.cs . Why is it a class implementing an interface versus a class inheriting an abstract-class . Don t reply saying that you cannot put a servicecontract attribute over the abstract-class . I know you can only apply it to interfaces but why .. . Answer : Several reasons I can think of : .. . .. . A clear statement of intent - this set of API signatures is totally decoupled from any possible implementation . By contrast an abstract-class in my opinion is more a statement of this base-class was designed to work with this set of derived classes . More open for modification - once you inherit one base-class that s it . Since a ServiceContract has no implementation why waste the one inheritance slot you have on it For example all our service classes inherit from an abstract ServiceBase class which provides common context state and methods in addition to implementing the ServiceContract interface . However even if that were not the case I would still leave the base-class slot free for future use . It permits one service class to implement more than one ServiceContract if appropriate . If you are using a strict contract versioning system that relies on inheriting one ServiceContract from another then adding service classes to the same inheritance tree will ruin it .", "Question : What exactly is a service contract in WCF I can t seem to be able to find a clear definition of what is it . If you have have a link that defines what it is that would be great . .. . Answer : A Service Contract is an interface which has been marked with the ServiceContractAttribute http : msdn.microsoft.com en-us library system.servicemodel.servicecontractattribute.aspx . This is the API that gets pushed across the wire in WCF and the main way to define the contract that is used for communication between the client and service .

Answer : I think the suggestion of creating a generic endpoint is a bad idea . By creating a method that takes any sort of input you ve lost all the strong-typing benefit that WCF in C gets you . You still have to do the hard work of dealing with old clients but now you have to do it in application code by inspecting the data coming in and heuristically deciding which version it assumes . In my mind it s similar to creating a single SQL database-table with dozens of columns named id data1 data2 data3 data4 etc . then storing all kinds of unrelated data in that one table . If the contract changes you need to make are backwards-compatible then you can add them to the contract in-place . Adding a new method is backwards-compatible since it doesn t affect the availability of the existing methods . If you need to make backwards-incompatible changes such as removing a method or changing the parameters of an existing one the easiest answer may be to create a new contract that lives at a new address . If version 1 of your contract is reached at http : example.com v1 MyService then version 2 is reached at http : example.com v2 MyService . To avoid duplicating a lot of code between classes where the contract didn t change much the classes that implement the contracts might inherit from each other . One way to do this could be : .. . .. . Or you can use composition : .. . .. . This way MyNewService implements all the functionality of MyService but only the methods exposed by INewService will be available via WCF . Anybody who accesses your service via the v2 URL will get the new functionality . Clients who are using the old service will continue to use the v1 URL until they re ready to upgrade .", "Question : In a WCF service is it possible to include a data member inside a ServiceContract definition Doing something like this : .. . .. . Can I expose MyDataMember from inside the ServiceContract The scenario would go like this : The following class which implements the service contract has member data that I would like to expose using a public field property . Something that looks like this : I m trying to expose a field property in a class which implements a service contract . For example : Comment : What are you trying to achieve here You have to return data via OperationContract calls and pass that data back in via other calls . Comment : Edited the question @ChrisF .. . Answer : You cannot inherit DataMember attribute . Definition is on msdn https : msdn.microsoft.com en-us library system.runtime.serialization.datacontractattribute.aspx . Although this does not technically restrict you to decorate interface members with DataMember attribute however you will have to decorate implementing classes members with this attribute too . Which is not intended way of use .", "Question : This MSDN article http : msdn.microsoft.com library ff183866.aspx recommends always to provide a namespace to a ServiceContract and DataContract .

Answer : My first instinct was to say that one can t have more than one direct child element of the SOAP Body element . But the SOAP specification https : www.w3.org TR soap12-part1 soapbody says that it s fine to do so . I don t think that WCF based on ServiceContract can do it though .

The values should be interpreted as an array of string . Is there any possibility to use this type of parameter in an OperationContract and define this in the UriTemplate .. . Answer : Your Service Contract interface is just that - a formal contract between what the server will accept and what the client needs to adhere to . This contract is serialised in to XML in the form of the wsdl - so any data types which appear in your contract must be expressible in their serialised form in XML . In your case the number of the arguments to your service call is not well-defined : it could have 0 1 2.. . etc .

Also pay attention that in your code you call GlobalProxy.getMyObject s but service contract has getMyObject method . .. . Answer : It seems to me like you re trying to pass objects static property through service call If so than that s simply not possible . Statics don t get serialized because serialization is instance based . You could probably pass static by encapsulating it in a non-static property like this : .. . .. . Having said that whenever you encounter this kind of hack it s probably a good idea to reconsider your design - does your field really need to be static Maybe you need to transfer some other object and only put it s results in your singleton static-class For example I m guessing you re using myObject as a sort of cache - you could put the cache in a singleton class this would make it transferrable via WCF and on client initialize it with what you got from service side . There are of course other valid options but and I m pretty sure that using static isn t a good choice here.. . Comment : Thanks Its true that I m porting a webapplication that used a global.asax to a windows service so maybe the design needs looking at although I wasn t aware statics didnt get serialized - what kind of silliness is that but I often use statics as a simple way of implementing the singleton pattern - so much so that any other singleton implementation i.e . if singletonClass null return new singletonClass feels like a hack to me now .", "Question : This should be easy for someone familiar with the best practices of versioning service data contracts .

But I have to use existing database-table which has slightly different column names than the default table structure for ZfcUser . In ZfcUser wiki page https : github.com ZF-Commons ZfcUser wiki ZfcUser-Concepts-and-Goals it says that it is possible to use custom mapper if my model doesn t conform to the provided interface .

But I can tell ZfcUser to work with my own class easily by overriding setting in file config autoload zfcuser.global.php : .. . .. . But I ve not found an easy way to tell ZfcUser to use my mapper class so far . I have only found that the mapper is created by ZfcUser Module : : getServiceConfig inside which I can see the mapper is returned from its factory function : .. . .. . Is there a way to make ZfcUser to use my custom user mapper class .. . Answer : I ve had the same problem as you but managed to log in to my application at last . I followed Rob s advice and created my own service factory within my existing user module . Unfortunately Bernhard is also spot on . You kinda have to dig into the ZfcUser source code to get it to work . The project I am working on now has a MSSQL server and I must say that it s been tough getting a handle on things . I ve ended up tweaking only one function in the ZfcUser source to get the login page to work . I only need log in functionality for the current application but the upcoming project is much more role driven . I was looking for something that wouldn t be too complicated to hook up quickly and at the same time offer more options and possibilities for the future . Here is what I did for now and what I ve learned : .. . .. . I copied the Entity and Mapper folders from the ZfcUser directory over to my existing b2bUser my module folder . Everything...even the Exception folder inside Mapper . It might not be necessary but I wasn t in the mood to figure out dependencies . In the zfcuser.global.php file my active configuration looks as follows : .. . .. . I left the rest of the settings on default . I removed the email option from auth identities because they won t use email addresses to log into the system . The user entity class is the one I copied over.. . .. . .. . Module.php b2bUser Copied the following to the service manager config : .. . .. . After the setup was done I changed the namespaces etc of the files in Entity and Mapper to reflect their new home . Changed the Entity and the Interface to reflect my own data structure . I did the same with the Mapper files and made sure the variable names in the Hydrator file is the same as my database column names . I left the AbstractDbMapper file where it was . But this is the file I tweaked a bit . Here is what mine looks like . The SQLSRV driver was full of pooh complaining the whole time about an object or a string.. . .. . .. . And that is that . I hope it helps someone to get it up and running on their own system at least . I won t leave mine like this but it was a bit of a mission to get it to work .

I m having some problems with modules ZfcUser and zfcuserDoctrineORM . I need to integrate them into my project .

Can the module be adapted to work with annotations If this is possible how do I adapt my entity user to this module Which archives should I modify .. . Answer : You don t need to adapt ZfcUserDoctrineORM https : github.com ZF-Commons ZfcUserDoctrineORM to use annotation mappings . DoctrineORMModule https : github.com doctrine DoctrineORMModule supports mixed mappings natively it s your choice to decide which entities to map with which drivers .
