OpenSSO build I installed on Tomcat. However, that download was not working for me for some reason. So, instead, I got the June 30 download of this agent, at this location:
 Anyway, you can download a build with which you're comfortable. Look here:
 By the way, I'm downloading the agent in to the following directory: /pa3gf
 2. Unzip the zip file.
 For example:
 # unzip
 3. Stop the GlassFish domain with the following command (from the root directory):
 # glassfish/bin/asadmin stop-domain domain1
 If you don't shutdown the domain before creating the agent, it will modify files.
 4. Change to the directory that contains the agentadmin utility. For example:
 # cd /pa3gf/
 5. Set the permissions for the agentadmin utility. For example:
 # chmod 755 agentadmin
 6. Start the agent installation. For example:
 #./agentadmin --install
 I used./agentadmin --install instead of./agentadmin --custom-install.
 7. Complete the installation as described in the substeps that follow:
 1. Continually press enter to accept the various parts of the license agreement.
 2. Enter yes to accept the complete agreement.
 You must then answer the agent installer prompts. Many of your responses will be responses you provided when you created the agent profile.
 3. Respond to the following prompt:
 Enter the Application Server Config Directory Path
 I responded with the following:
 4. Respond to the following prompt:
 Federated Access Manager URL:
 I responded with the name of the Tomcat server, on which I installed OpenSSO:
 5. Respond to the following prompt:
 Agent URL:
 I responded with the name of the GlassFish instance including the port for domain1:
 6. Respond to the following prompt:
 Enter the Agent Profile name:
 I responded with the following:
 7. Respond to the following prompt:
 Enter the path to the password file:
 I responded with the following:
 Then, a summary of your responses is displayed as such:
 Application Server Config Directory :
 Federated Access Manager URL :
 Agent URL :
 Agent Profile name : glassfishagent
 Agent Profile Password file name : /pa3gf/gfagentpw
 Verify your settings above and decide from the choices below.
 1. Continue with Installation
 2. Back to the last interaction
 3. Start Over
 4. Exit
 8. Respond to the following prompt by providing one of the options listed at the end of summary.
 Please make your selection [1}
 I responded with the following:
To Deploy Applications on GlassFish
There are a few ways to deploy applications on GlassFish. This task shows the method I used. I deployed two applications at the same time. The agentapp.war file is used for housekeeping tasks. The agentsample.ear file is the J2EE agent sample application, which gives you the opportunity to practice protecting an application with the agent. Therefore, you can create policies and perform other tasks that control access to the application. I plan to add a blog entry in the future about using the sample application, so I've decided to deploy it now.
 1. Copy the agentapp.war file and the agentsample.ear file to the GlassFish autodeploy directory. For example, from the root directory, I issued the following commands:
 # cp /pa3gf/j2ee_agents/appserver_v9_agent/etc/agentapp.war /pa3gf/glassfish/domains/domain1/autodeploy
 # cp /pa3gf/j2ee_agents/appserver_v9_agent/sampleapp/dist/agentsample.ear /pa3gf/glassfish/domains/domain1/autodeployGlassfish Console: Left Pane
 2. Start the GlassFish server with the appropriate command. For example I issued the following command (from the root directory):
 # pa3gf/glassfish/bin/asadmin start-domain domain1
 When the domain starts, the two applications will deploy.
 3. Verify that the Application Server is running and the two applications were deployed as described in the substeps that follow:
 1. Using a browser, access
 2. Log in with the proper credentials. For example:
 User name: admin
 Password: adminadmin
 4. In the left pane, click the arrows next to the following labels:
 - Enterprise Applications
 - Web Applications
 You should see the two applications you just deployed, the agentsample and the agentapp, as illustrated in the image to the right.
 Now things are set for you to experiment with the sample application, which is what I'd like to get into soon myself. Hopefully, I'll be blogging about my travails with the sample application soon.
 As I mentioned at the beginning of this entry, Sean Brydon has written up quite a bit about the J2EE sample applicaton, the quick example is here and the detailed example is here.

Icon of the Mother of God "Chukhloma"
The Chukhloma Icon of the Mother of God of Galich appeared in 1350 to St. Abraham of Galich, who came from the north to live an ascetic life with the blessing of St. Sergius of Radonezh. On the shores of Galich Lake which was hidden in a dense forest, he turned with prayer to the Mother of God, asking Her blessing. After finishing his prayers, he sat down to rest, but suddenly a bright light appeared on a nearby mountain and a voice said, "Abraham, come up the mountain, where there is an icon of My Mother."
The monk went up the mountain where the light shone, and indeed found an icon of the Mother of God with the Infant on a tree. With tenderness and in gratitude to God, he took the icon and, strengthened by prayers to the Most Holy Theotokos, built a chapel there in which he placed the icon.
Galich Prince Demetrius Feodorovich learned about St. Abraham's trip, and asked him to bring the icon to him. St. Abraham journeyed across Galich Lake in a boat and, accompanied by clergy and a throng of people, took the wonderworking icon to the cathedral church in the city of Galich.
A large number of sick were healed by this icon. When St. Abraham told Prince Demetrius about the appearance of the icon, the Prince gave St. Abraham money to build a monastery. Soon, a church was built in honor of the Dormition of the Most Holy Theotokos, around which a monastery grew. St. Abraham founded several more monasteries, the last being the Chukhloma, not far from the city of Chukhloma. From the name of this monastery, the wonderworking icon became known as the Chukhloma Icon of Galich.
The icon is also commemorated on May 28, July 4, and August 15.

A humanoid robot is a robot with its overall appearance based on that of the human body.
In general humanoid robots have a torso with a head, two arms and two legs, although some forms of humanoid robots may model only part of the body, for example, from the waist up.
Some humanoid robots may also have a 'face', with 'eyes' and'mouth'.
Androids are humanoid robots built to resemble a male human, and Gynoids are humanoid robots built to resemble a human female.

Lennon's letters offer intimate insight
The cover of The John Lennon Letters.Photo / Supplied
The cover of The John Lennon Letters.Photo / Supplied
One of the main reasons Facebook, Twitter and other voyeuristic social networking tools are popular is pretty obvious - we like to spy on other people.
I've always been a fan of reading letters of long-gone celebrities. Many famous writers were also compulsive note-writers. There have been volumes of letters produced by Ernest Hemingway, J.R.R. Tolkien, Virginia Woolf, Abraham Lincoln, amongst others.
It might be a dying art form, but a handsome new book shows the fleeting beauty tossed-off notes and messages can have.
The John Lennon Letters, compiled by Beatles biographer Hunter S. Davies, features dozens of notes written by Lennon in his lifetime and is a cornucopia for both Beatlemaniacs and letter-spies.
"Lennon lived before computers and email and texts and his first reaction was to write things down," Davies writes.
"He saw them as a little performance."
The John Lennon Letters is a well designed book for die-hard Beatles fans, featuring nearly 300 of Lennon's letters extensively notated and reproduced with his own squiggly handwriting and scribbly cartoons. Each letter has had its history tracked down by Davies, and the context is invaluable, making this a kind of scrapbook biography of Lennon through his letters.
Its scattered contents include everything from letters to fans and other famous folks to mundane shopping lists and surreal insults. Many of the later letters get so lost in Lennon's cryptic wordplay that they're like reading James Joyce's Ulysses to decipher.
One curious omission in the book is any real letters between John and his wife Yoko Ono. Davies says they barely ever wrote each other as they were always together. However, there are plenty of letters that hint at real emotion from behind Lennon's joking, caustic exterior like the early letters to his first wife, Cynthia, or his friend Stuart Sutcliffe, who was briefly a member of the Beatles and died of brain haemorrhage at only 21.
In a 1961 letter to Sutcliffe, Lennon writes: "I can't remember anything without a sadness so deep that it hardly becomes known to me."
This was well before Love Me Do and She Loves You, but the darker Lennon of "Plastic Ono Band" is already evident.
And it's hard not to read a line from a 1979 letter without wincing, just a bit: "I'm 40 next year - I hope life begins."
Lennon's image has gone through many reinventions since his early death, from hippie saint to grouchy genius. What's great about The John Lennon Letters is every facet of his complicated, imperfect personality shines through.
The golden age of the letter may have passed, but a tome like this is a reminder of what a window into a person's mind they could be.
The best books of correspondence:
1. Fear and Loathing in America by Hunter S. Thompson: Thompson was a prolific letter-hack and this volume collects hundreds of letters from 1968 to 1976, as America rambled through the 60s, Vietnam, Watergate and more.
2. The Portable Abraham Lincoln: America's greatest president created some fine letters, speeches and other writings. A highlight is the letter to Lydia Bixby, a widow who lost five sons in the US Civil War.
3. Kurt Vonnegut: Letters: Published just in time to mark what would have been Vonnegut's 90th birthday, this massive tome is a treasure trove of wry wit and curmudgeonly observations, including a harrowing letter on his combat experiences in Dresden, Germany during World War II.
4. The Adams-Jefferson Letters: A joint book collecting the correspondence between the second and third American presidents in the final years of their lives, from 1777 to 1826. It touches on both the political and the personal in a take on American history by two who were there from the start.
The Yage Letters by William S. Burroughs and Allen Ginsberg: A fascinating piece of druggy history, featuring letters written by Burroughs while on a South American trip to track down the legendary yage vine, which was claimed to possess strange powers. It's hallucinogenic travel tales and quite possibly halfway made up, but also terrific letter-writing.
* The John Lennon Letters, published by Little, Brown and Company is available now. RRP NZ$59.99.

ndisc6 [-1mnqv] [-r attempts] [-w wait_ms] < IPv6 address>
NDisc6 is an Unix program which implements the ICMPv6 Neighbor Discovery in userland (it is normally done by the kernel). It is used to lookup the link-layer address (layer 2 address, MAC in the case of Ethernet) of any on-link IPv6 node.
The IPv6 address of the node must be specified, as well as the networking interface on which to perform the lookup.
-1 or --single
Exit as soon as the first advertisement is received (default).
-h or --help
Display some help and exit.
-m or --multiple
Wait for possible duplicate advertisements and print all of them.
-n or --numeric
If the first parameter is not a valid IPv6 address, do not try to resolve it as a DNS hostname.
-q or --quiet
Only display link-layer address. Display nothing in case of failure. That is mostly useful when calling the program from a shell script.
-r attempts or --retry attempts
Send ICMPv6 Neighbor Discovery that many times until a reply is received, or abort. By default, ndisc6 will try 3 times before aborting (MAX_MULTICAST_SOLICIT and MAX_UNICAST_SOLICIT from RFC2461).
-V or --version
Display program version and license and exit.
-v or --verbose
Display verbose information. That is the default.
-w wait_ms or --wait wait_ms
Wait wait_ms milliseconds for a response before retrying. By default, ndisc6 waits 1 second between each attempts (RETRANS_TIMER from RFC2461).
If you get no response while you know the remote host is up, it is most likely that it is not on-link, that is to say, you must cross one or more routers to reach it. By design, IPv6 nodes ignore ICMPv6 Neighbor Discovery packets received from nodes not on the same link (i.e. Ethernet segment), for the sake of security. Technically, that is done by ensuring that the Hop limit (TTL) is 255.
Note that you cannot use ndisc6 to lookup the local host's link-layer address.
ndisc6 should be setuid root to allow use by non privileged users. It will drop its root privileges before any attempt is made to send or receive data from the network to reduce the possible impact of a security vulnerability.

I'm working on strengthening my F#-fu and decided to tackle the Facebook Hacker Cup Double Squares problem. I'm having some problems with the run-time and was wondering if anyone could help me figure out why it is so much slower than my C# equivalent.
There's a good description from another post;
Source: Facebook Hacker Cup Qualification Round 2011
A double-square number is an integer X which can be expressed as the sum of two perfect squares. For example, 10 is a double-square because 10 = 3^2 + 1^2. Given X, how can we determine the number of ways in which it can be written as the sum of two squares? For example, 10 can only be written as 3^2 + 1^2 (we don't count 1^2 + 3^2 as being different). On the other hand, 25 can be written as 5^2 + 0^2 or as 4^2 + 3^2.
You need to solve this problem for 0 ≤ X ≤ 2,147,483,647.
10 => 1
25 => 2
3 => 0
0 => 1
1 => 1
Numbers From Competition
My basic strategy (which I'm open to critique on) is to;
 1. Create a dictionary (for memoize) of the input numbers initialzed to 0
 2. Get the largest number (LN) and pass it to count/memo function
 3. Get the LN square root as int
 4. Calculate squares for all numbers 0 to LN and store in dict
 5. Sum squares for non repeat combinations of numbers from 0 to LN
 - If sum is in memo dict, add 1 to memo
 6. Finally, output the counts of the original numbers.
Here is the F# code (See code changes at bottom) I've written that I believe corresponds to this strategy (Runtime: ~8:10);
open System

open System.IO

let rec range min max =

let rec maxNum acc = function

/// A helper for finding max that sets the accumulator to 0
let rec findMax nums = maxNum 0 nums

let rec combos range =

 for inner in range do
 for outer in Seq.skip!count range do
 yield (inner, outer)

let rec squares nums =
 let dict = new Dictionary()
 for s in nums do
 dict.[s] <- (s * s)
/// Counts the number of possible double squares for a given number and keeps track of other counts that are provided in the memo dict.
let rec countDoubleSquares (num: int) (memo: Dictionary) =
 // The highest relevent square is the square root because it squared plus 0 squared is the top most possibility
 let maxSquare = System.Math.Sqrt((float)num)
 // Our relevant squares are 0 to the highest possible square; note the cast to int which shouldn't hurt.
 let relSquares = range 0 ((int)maxSquare)
 // calculate the squares up front;
 let calcSquares = squares relSquares
 // Build up our square combinations; ie [1,2,3] = (1,1), (1,2), (1,3), (2,2), (2,3), (3,3)
 for (sq1, sq2) in combos relSquares do
 let v = calcSquares.[sq1] + calcSquares.[sq2]
 // Memoize our relevant results
 if memo.ContainsKey(v) then
 memo.[v] <- memo.[v] + 1
 // return our count for the num passed in
// Read our numbers from file.
//let lines = File.ReadAllLines("test2.txt")
//let nums = [ for line in Seq.skip 1 lines -> Int32.Parse(line) ]
// Optionally, read them from straight array
let nums = [_PHONE_; _PHONE_; _PHONE_; 602519112; 858320077; _PHONE_; 415485223; 874566596; _PHONE_; 65; 421330820; _PHONE_; 5; _PHONE_; _PHONE_; 4225; _PHONE_; 0; 1; 3]
// Initialize our memoize dictionary
let memo = new Dictionary()
for num in nums do
 memo.[num] <- 0
// Get the largest number in our set, all other numbers will be memoized along the way
let maxN = findMax nums
// Do the memoize
let maxCount = countDoubleSquares maxN memo
// Output our results.
for num in nums do
 printfn "%i" memo.[num]
// Have a little pause for when we debug
let line = Console.Read()
And here is my version in C# (Runtime: ~1:40:

Thanks for taking a look.
Changing the combos function slightly will result in a pretty big performance boost (from 8 min to 3:45):

 let rangeCache = Seq.cache range
 let count = ref 0
 for inner in rangeCache do

/// The New Hotness...
let rec combos maxNum =
 seq {
 for i in 0..maxNum do
 for j in i..maxNum do

What is a Reverse NDR Attack
The non-delivery report (NDR) is generated when an email message is not able to be sent to the next hop.
Spammers can use NDR as a method to generate spam towards victims by using the victim's email address as the sender. This is called a reverse NDR Attack.
Consider the following scenario:
 - Bob (the victim), has an email address
 - You run an email server that accepts messages for In addition, it accepts messages for valid as well as invalid users.
 - Jim (the attacker), wants to send a spam message to Bob. However, instead of sending it directly to Bob, he sends it through your email server. He does this to prevent his IP address from getting black listed.
 - Jim's composes an email with the following values for Sender and Recipient:
Since does not exist, your email server will generate an NDR. However, that NDR will get sent to Bob instead of Jim, because Jim forged the sender to be Bob instead of Jim.
Refer to the diagram below for more information:
Preventing such attacks in Xeams
There are two features in Xeams that will help against a reverse NDR attack.
 - Configure Xeams to reject invalid users. This is done by specifying a valid list of users or integrating with Active Directory.
 - Configure how NDRs are generated.
 Configuring NDRs
 After logging in as admin, go to Smtp Server Configuration and select the Advanced Tab. Following bullets describe two important configuration parameters.
 Include Original:
 This option configures whether to attach the original email message in the NDR. By default, this option is disabled. It is highly recommend to leave this option disabled to prevent spammed messages.
 Generate NDRs only for outbound emails:
 This option only allows NDRs to be generated for outbound emails. This prevents the reverse NDR attack where someone uses your email server to bounce back spam messages.

¡Bienvenidos a Chapala Mexican Restaurant!
We're a family business and we first opened our doors in April of 2019 with the hope of bringing authentic and delicious Mexican food made with love to the Denver area. Thank you for coming to dine with us, and we're excited to provide y'all with the best food and service in town!
A brief history of Chapala:
Chapala is a town and municipality in the central Mexican state of Jalisco, located on the north shore of Lake Chapala, Mexico's largest freshwater lake.
Until the arrival of the Spanish in the 16th century, nomadic Amerindian tribes, including the Nahuatl, occupied the Lake Chapala region. They migrated from northwestern Mexico and gave rise to the Aztec civilization. Chapala is named after the last chief of the Nahuatl, Chapalac. Ajijic, the second largest town along the lake's northwestern shore, received its name from the Nahuatl word for "Place where the water springs forth."
Lake Chapala in southeastern Jalisco is Mexico's largest lake, occupying about 1,112 square kilometers (430 square miles). The lake provides critical habitat for several species of migratory birds, including the white pelican.

1 Pedagogical Variation with Computers in Mathematics Classrooms: A Cultural Historical Activity Theory Analysis
Authors: Joanne Hardman
South Africa's crisis in mathematics attainment is well documented. To meet the need to develop students' mathematical performance in schools the government has launched various initiatives using computers to impact on mathematical attainment. While it is clear that computers can change pedagogical practices, there is a dearth of qualitative studies indicating exactly how pedagogy is transformed with Information Communication Technologies (ICTs) in a teaching activity. Consequently, this paper addresses the following question: how, along which dimensions in an activity, does pedagogy alter with the use of computer drill and practice software in four disadvantaged grade 6 mathematics classrooms in the Western Cape province of South Africa? The paper draws on Cultural Historical Activity Theory (CHAT) to develop a view of pedagogy as socially situated. Four ideal pedagogical types are identified: Reinforcement pedagogy, which has the reinforcement of specialised knowledge as its object; Collaborative pedagogy, which has the development of metacognitive engagement with specialised knowledge as its object; Directive pedagogy, which has the development of technical task skills as its object, and finally, Defensive pedagogy, which has student regulation as its object. Face-to-face lessons were characterised as predominantly Reinforcement and Collaborative pedagogy and most computer lessons were characterised as mainly either Defensive or Directive.

Current methods for topology optimization primarily represent the interface between solid and void implicitly on fixed grids. In contrast, shape optimization methods represent the interface explicitly, but do not allow for any topological changes to the structure. Using an explicit interface representation has a number of advantages as described below. Consequently, we propose to use the Deformable Simplicial Complex (DSC) method which represents the interface explicitly as one or more closed piecewise linear curves in 2D. As opposed to pure shape optimization methods, the DSC method is able to handle topology changes. It does so by discretizing the entire design domain into an irregular adaptive triangle mesh and thereby explicitly representing both the structure and the embedding space. In other words, the entire design domain is divided into triangles, where the interface is represented as piecewise linear curves between void and non-void triangles. Another advantage of the DSC method is that we can exploit the triangle mesh for the FEM computations used in the optimization procedure. The non-void elements define the structure and their deformation is described by second order shape functions. To increase performance, degrees of freedom associated with void triangles are eliminated from the FE equation. Using the triangle mesh for computations is possible since the DSC method ensures a mesh with no degenerate elements. If the mesh contained degenerate or close to degenerate elements the FEM computations would break down and the results would no longer be valid. The DSC method solves this issue by a series of mesh operations which keeps the mesh ever well-formed. Put another way, the consequence of using a well-formed adaptive mesh is that the representation for the FEM calculations and the shape of the structure can be one and the same. In addition to unifying calculations and representation of the structure, the approach also unifies shape and topology optimization into a single framework. Furthermore, it combines the two in a simultaneous optimization strategy. Here, the shape is optimized on the basis of the gradient based optimization algorithm Method of Moving Asymptotes whereas holes are introduced using topological derivatives. Since we combine these methods, and since FEM calculations are performed only on non-void triangles and gradients are calculated only for the interface nodes, the presented approach is efficient. An explicit representation is not just useful when considering simplicity and performance. In many cases, the explicitly represented interface is necessary to be able to model a problem. For example for ow or electromagnetic problems with localized boundary effects. Furthermore, control of boundary smoothness is simple to implement and can e.g. be used to control fillet radius at corners. The method also opens up for the opportunity to apply other local constraints, such as min/max length scale of the structure. Finally, the explicit interface is in all cases necessary when interpreting the final design. The status of the work is that the method has been developed and is showing promising results. For instance, the cantilever beam problem has been solved to a high precision using a fine discretization by evaluating the objective function approximately 500 times. This took around 100 seconds on an ordinary laptop utilizing a single thread. In addition, a coarse solution to the same problem has been obtained in approximately 10 seconds.

How to turn real-world sounds into FX
We take the sound of a waterfall and turn it into a riser effect
Turning real world sounds into FX
Recordings of noise or ambience from the real world often contain interesting textures and harmonics - the sounds around you can be ideal sources for some creative FX design.
Here, we're going to show you how a simple recording can be turned into something else entirely using a variety of processing techniques.
For a complete guide to creative sound design check out Future Music issue 281, which is on sale now.
Step 1: We've taken our trusty field recorder out into the real world and captured a recording of a waterfall, giving us a characterful noise bed to begin with. Although you can use traditional white noise from a synth for this kind of effect, a field recording often provides more interesting results.
Step 2: Instead of processing this sound as an audio file directly on the timeline, we import our recording into our DAW's sampler instrument, allowing us to manipulate the sound using advanced synthesis functions. Field recordings will often contain muddy low content, so the sampler's high-pass filter is engaged to remove any rumbling sub frequencies that can easily clog up the bottom end of a mix and clash with other low track elements.
Step 3: We can now turn our waterfall recording into more of a mechanical evolving rise by making use of the sampler's loop points. By cycling around a smaller portion of the recording, and then automating the Loop Length parameter, we can shorten our loop length over time to create a robotic stutter-like effect as the sound progresses. It's quite subtle at this stage, but we can amplify this effect with some further manipulation.
Step 4: To transform our noisy bed of sound into an uplifting riser, we initially automate the MIDI region's pitch bend to increase by an octave as the sound opens out. This doesn't provide enough of an extreme effect, so we also automate the sampler's Transpose parameter to make the recording's pitch rise over four octaves or so. Although we've automated the sampler and MIDI parameters to affect pitch here, you could use a dedicated real-time pitch-shifting plugin.
Step 5: Once you have a frequency-rich sound that you're happy with, you can creatively filter those frequencies for progression and movement over time. Here we apply UAD's Moog Filter to low-pass our rising noise, opening out the Cutoff to reveal our 'whoosh' effect. Cranking up the plugin's Drive dial gives us more dirt and dynamic levelling, but you can use a separate saturation plugin placed before the filter if your plugin is missing a drive stage.
Step 6: Now the core effect is complete, it's time to have fun and experiment with creative modulation and spatial effects. We've kept things simple, only adding delay and reverb in the form of SoundToys' EchoBoy and UVI's Sparkverb, but you can really go all out and tweak different plugin combinations. Some subtle bitcrushing or distortion can add more bite, or a modulation plugin like a flanger or chorus can provide some interesting width and movement.

Consuming an ASP.NET Web Service from Salesforce Apex Callouts
Salesforces wsdl2apex can be a bit basic in what is supports (see Supported WSDL Features).
Steps for consuming an ASP.NET web service from Apex.
 1. Add the Web service host to the Remote Sites.
 Adminitraction Setup > Security Controls > Remote Site Settings
 Skipping this step will result in a "System.CalloutException: IO Exception: Unauthorized endpoint, please check Setup->Security->Remote site settings. endpoint ="...
 2. Export the WSDL from the ASP.NET web service
 3. Optionally, you might like to sort the WSDL. The idea is to ensure wsdl2apex produces the same elements in the same order for future code comparisons.
 4. Import the WSDL into Salesforce
 Develop > Apex Classes > Generate from WSDL*
 5. Define a Apex class name
 6. Test the new Apex class using Execute Anonymous in Eclipse. With a ASP.NET generated web service I found the class I defined in the previous step had a nested class corresponding to the binding name from the uploaded WSDL. The nested class had a method that corresponded to the web method (the operation in the WSDL).
 7. Optionally, search the generated class for calls to WebServiceCallout.invoke(...). This will currently cause test cases to abort silently (except for a log message) and you may not notice. Sprinkle the code with a liberal amount of Test.isRunningTest().
*Common WSDL parsing errors:
 1. If the Parse WSDL button produces Error: Failed to parse wsdl: Found more than one wsdl:binding. WSDL with multiple binding not supported Deleting the second element what contains soap12 elements and the corresponding port definition under .
 2. wsdl:import
 Error: Failed to parse wsdl: Unknown element: import
 Locate the import elements in the current WSDL. E.g.. Pull that WSDL down and merge its contents into the parent WSDL.
 3. xsd:import
 Failed to parse wsdl: Found schema import from location External schema import not supported
 These will typically appear under . Copy the contents of the import under and remove the . See also: Discussion Forum: Referencing external schemas in a WSDL
 4. Error: Failed to parse wsdl: Failed to parse WSDL: Unable to find binding {}BasicHttpBinding_IWebService. Found BasicHttpBinding_IWebService instead.
 The had the attribute xmlns:i0="". i0: was being used as the namespace for the binding. Switching it to tns: resolved the issue.
 5. Error: Failed to parse wsdl: schema:targetNamespace can not be null
 In this case I needed to add a targetNamespace attribute and value to the element. E.g. becomes
 6. Apex Generation Failed:
 Unable to find schema for element; {}ArrayOfstring
 Unable to find schema for element; {}ArrayOflong
 In this case I'd initially made a mistake when pulling in the xsd for these complex types. I corrected it by putting the complex type definitions within a element in wsdl:type section.
 7. Error: wwwExampleComApi
 Error: Identifier name is reserved: long at 191:23
 This error was caused by the ArrayOflong type generating the following Apex:
 public class ArrayOflong {
 public Long[] long;
 private String[] long_type_info = new String[]{'long','','long','0','-1','false'};
 private String[] apex_schema_type_info = new String[]{'','false','false'};
 private String[] field_order_type_info = new String[]{'long'};
 Possible fix:
 public class ArrayOflong {
 public Long[] long_x; // Note the _x suffix to avoid the conflict
 // The first parameter here is what will appear in the SOAP message as the element name
 private String[] field_order_type_info = new String[]{'long_x'};
 8. Error: Failed to parse wsdl: Unsupported Schema element found At: 1866:57
 The WSDL had three "attribute" elements:
 -
 -
 -
 Commenting these out of the WSDL allowed into to be used with wsdl2apex. I'm not sure what adverse effects resulted from removing them.
 9. The use of in a complex type won't result in the base class fields appearing in generated Apex class.
 Try copying the fields from Apex class that was being extended into the sub class.

 1. hi
 i got unable to find schema for element.
 how can i solve this problem
 2. Hello Daniel,
 I am getting the following error, let me know if you have any solution for this
 Error: Failed to parse wsdl: Unable to find schema for element; {}schema
 Thanks in advance!!
 1. Hi Arish,
 Most likely your WSDL contains a "schema" element. Have a look at the Supported WSDL Features of WSDL2Apex.
 3. Thanks for the post. Helped a lot in generating my first apex class from.net wsdl file. I have a query.
 Along with the wsdl file, I have been provided with a dll(Miscrosoft.ServiceBus.dll) file which has some bindings to be used. I haven't used this to generate the code. When I try to get the output, I get the following error:
 Cannot send message because the service endpoint hosted at the specified address uses a binding that cannot be accessed over HTTP.
 So, how do I use this dll file and bind it to the WSDL file to generate the apex class? The binding need to be included in the generated class also.
 Please let me know.
 1. Hi "Man"ish,
 You won't be able to utilise a.NET DLL directly in Salesforce apex.
 If I had to guess from the error message you will probably need to use https rather than http.
 Try changing the endpoint_x in the wsdl2apex generated class.
 Failing that, see if you can get a sample SOAP message from a valid call to the web service and compare that to what Salesforce is generating.
 4. Hi,
 I am getting this error. Can someone tell why is this happening and how to fix this?
 Apex Generation Failed
 Unsupported WSDL. Found more than one part for message setCurrentScopeById
 1. Have a look at The WSDL most likely contains multi-part messages. You may be able to manually manipulate the WSDL to still import it with wsdl2apex.
 5. hey..
 i am getting an error
 Apex Generation Failed
 Unable to find schema for element; {}double
 so cud u plz give ant solution..
 although i have gone thru ol the supported wsdl constructs..yet not able to import even a single external wsdl file...
 here is my document plz have a look
 1. It's hard to day without seeing the schema. The schema link you provided is for a binary download, which I'm not game to try because of the potential security risk. would be a good place to post the question and the problem schema details.
 6. Nice post. what will you advice for a requirement implemented using 'Outbound Messages' which ensures of retrying and delivering the message.
 However how to handle and show the error on SF GUI thats sent by external system, due to some data error (as data is not saved in external system), As this failure is data error, outbound monitor message shall not retry to send.Any advice will help.
 1. When you are processing the outbound message you can get the Salesforce Session ID and ServerURL. You can use these to write data back to Salesforce. This could include any problem records that need manual follow up.

Count Entities
Count Departures Across the Simulation
Use the _TAG_ or _TAG_ output signal from a block to learn how many entities have departed (or arrived at) the block. The output signal also indicates when departures occurred. This method of counting is cumulative throughout the simulation. These examples use the _TAG_ output signal to count departures:
Count Departures per Time Instant
Suppose you want to visualize entity departures from a particular block, and you want to reset (that is, restart) the counter at each time instant. Visualizing departures per time instant can help you:
 - Detect simultaneous departures
 - Compare the number of simultaneous departures at different time instants
 - Visualize the departure times while keeping the plot axis manageable
Use the Instantaneous Entity Counting Scope to plot the number of entities that have arrived at each time instant. The block restarts the count from 1 when the time changes. As a result, the count is cumulative for a given time instant, but not cumulative across the entire simulation.
Count Simultaneous Departures from a Server
In this example (open modelmodel), the Infinite Server block sometimes completes service on multiple entities simultaneously. The Instantaneous Entity Counting Scope indicates how many entities departed from the server at each fixed time instant during the simulation.
Reset a Counter upon an Event
Suppose you want to count entities that depart from a particular block, and you want to reset the counter at arbitrary times during the simulation. Resetting the counter can help you compute statistics for evaluating your system over portions of the simulation.
The Entity Departure Counter block counts entity departures via a resettable counter. To configure the block:
 1. Decide which type of events you want to reset the counter. The choices are:
 - Sample time hits
 - Trigger edges
 - Value changes
 - Function calls
 These resources can help you choose which type of events:
 2. In the Entity Departure Counter block, indicate which signal-based events cause the counter to reset:
 - To reset upon sample time hits of an input signal, set Reset counter upon to Sample time hit from port ts.
 - To reset based on a trigger edge in an input signal, set Reset counter upon to Trigger from port tr. Then set Trigger type to Rising, Falling, or Either.
 - To reset based on a change in the value of an input signal, set Reset counter upon to Change in signal from port vc. Then set Type of change in signal value to Rising, Falling, or Either.
 - To reset upon function calls, set Reset counter upon to Function call from port fcn.
 3. If you want to specify an explicit priority for the reset event, select Resolve simultaneous signal updates according to event priority. Then enter the priority using the Event priority parameter.
 4. Click OK or Apply. The block now has a signal input port.
 5. Connect an event-based signal to the signal input port.
During the simulation, the block counts departing entities and resets its counter whenever the input signal satisfies your specified event criteria.
Reset a Counter After a Transient Period
This example (open modelmodel) counts entity departures from a queuing system, but uses a step block to reset the counter after an initial transient period.
Associate Each Entity with Its Index
Use the Entity Departure Counter block with Write count to attribute check box selected to associate entity counts with the entities that use a particular path. The Nth entity departing from the Entity Departure Counter block has an attribute value of N.
For an example, see Set Attributes.
For an example in which the Entity Departure Counter block is more straightforward than storing the _TAG_ output signal in an attribute, see Sequence of Departures and Statistical Updates.

Released Slaves in Malta and their spouses
Manumission is the act of a slave owner freeing his or her slaves. A released slave was called a 'manumesso'.
The motivations of slave owners in manumitting slaves were complex, as disparate as reconciliation with one's Maker, freeing a slave who is in fact an offspring of the owner, a reward for good service, or simply because the services are no longer needed and so on.
In Malta there also existed private foundations for the redemption of Maltese slaves: A portrait by the artist Favray in the chapel of Selmun shows Caterina Vitale, who gave up her lands to establish one such foundation. _URL_ This is to be explained in the context of the fact that it often happened that Maltese corsairs would be imprisoned and therefore made slaves of their hostile captors and often converted to Islam (as was the case of the boy Zammit _URL_ The purpose of these foundations was to free Maltese from their foreign captors. These Maltese slaves are therefore not to be confused with slaves in Malta who were invariably of non-European origin.
A slave would often but not necessarily always convert to Christianity. Sometimes we find reference to former slaves as neophytes as a euphemism for their former status.
The released slave would often take on the surname of the former master, sometimes adding the prefix "de" or "di" for difference. The later descendants would often drop the prefix.
In 1647, Abela noted that Malta's noble families had slaves. _URL_ In particular the noble family of Mamo is noted as having had many slaves. _URL_ Abela does not indicate whether any of such families were themselves originally of slave descent but it has been suggested that the more remote common ancestor of the counts Sant was an Ethiopian slave. _URL_
Although slavery and trading in slavery was abolished by Napoleon in 1798, we find documentary reference to Maltese involved in this trade even in the late 19th century, e.g. in 1860 Annibale De Bono, a trader from Malta, is described as the nephew of the slave trader Andrea De Bono who had a trading post in Southern Sudan. _URL_

Five new names have been approved for Mars: Angustus Labyrinthus, Chronius Mons, Promethei Mons, Sisyphi Tholus, and Thyles Montes. The names Australis Patera, Angusta Patera, and Cavi Frigores have been marked as dropped in the database. New imagery has shown that the two paterae were named using the wrong descriptor term, and the area previously named Cavi Frigores has been incorporated into the adjacent Cavi Angusti.
The definition of the descriptor term labyrinthus has been expanded from "Complex of intersecting valleys" to "Complex of intersecting valleys or ridges."

How Does a Dollar Peg Work?A country's finance minister will monitor his country's currency exchange rate relative to the dollar's value. If the currency falls below a certain range, he will buy dollars -- usually in the form of U.S. Treasuries. This increase the dollar's value so it once again falls within the intended range. If the dollar were to rise above the range, the country would sell its Treasuries to lower the dollar's value back within its targeted range.
Why Do Countries Peg Their Currency to the DollarHowever, most countries try to keep the value of their currency lower than the dollar. This gives them a comparative advantage by making their exports to America cheaper. A great example of this is China, which pegs its currency (the yuan) to the dollar to maintain competitive pricing.
Other countries, like the oil-exporting nations in the Gulf Cooperation Council, must peg their currency to the dollar because their primary export, oil, is sold in dollars. As the dollar has declined, they've become large owners of dollars in their sovereign wealth funds. These petrodollars are often invested in the U.S. to earn a greater return. In fact, Abu Dhabi invested petrodollars in Citigroup to prevent its bankruptcy in 2008. Countries that do a lot of trading with China or oil-exporting countries will also peg their currency to the dollar to remain competitive with their customer.

Regular Expressions: Positive and Negative Lookahead austin
Tell us what's happening:
I'm looking at the example given in the Positive and Negative Lookahead Lesson. Here it is:
let password = "abc123";
checkPass.test(password); // Returns true
However, if password = "abcd123" it still return as true, even though the password has more than 6 characters. Why is that? Shouldn't this return as false if there are more than 6 characters?
Also, I don't understand how the lookahead works when there is nothing in front of the (?=…) as given in this example. The other examples have something in front, as with q(?=u). How can you have a lookahead with nothing in front of the lookahead?
Your code so far
Your browser information:
Challenge: Positive and Negative Lookahead
Link to the challenge:
I'll translate this regex to English and see if you can spot the problem:
 1. Anywhere ahead of me there must be three to six _alphanumeric characters
 2. Anywhere ahead of me there must be a digit possibly preceded by any number of non-digit characters
DISCLAIMER: "Anywhere" is somewhat incorrect technically, but still OK to understand the behaviour.
Ok thank you that does help! It seems that this regex just checks to see if there are 3-6 alphanumeric characters in the string ("ahead of me"), but the string can still be more than 6 characters.
Exactly! There is no way lookaheads can test the maximum boundary. In order for this regex to work you need to unwrap the first lookahead and introduce boundaries ^...$:
const re = /^(?=.*\d)\w{3,6}$/;
re.test('abc123'); // true
re.test('abcd123'); // false

Kentucky Countryside in Transition
A Streetcar Suburb and the Origins of Middle-Class Louisville, 1850–1910
Kentucky Countryside in Transition charts the rise of the American middle class at the turn of the twentieth century by examining the migration from the Kentucky countryside to the city and subsequently the suburbs of Louisville. The formation of the middle class in Louisville was fostered by two factors: a boom in white collar employment and the electric streetcar, an innovation that fundamentally changed the urban landscape. Ultimately a narrative of industrialization and modernity, this study focuses on a group of forty-two families who lived at the end of the Broadway Trolley line in an area that came to be known as the Cherokee Triangle. This suburban neighborhood was dominated by white collar commuters who were driven to Louisville by a desire to get ahead but continued to embrace a nostalgia for country life. In this meticulous three generation study, Stephanie Bower follows this group of families as they make the transition from rural farmers and cultivators to city laborers and white collar workers. By mining census records, city directories, and county records, Bower carefully reconstructs the biographical details of residents in an effort to paint a picture of life in this streetcar suburb during this important period of transformation. Regional studies of the middle class during this pivotal era are often overlooked in contemporary scholarship. Consequently, this analysis will be of interest to those researching Louisville, middle class formation, and suburbanization, as well as to local genealogists tracing their family histories.

Animal Species:Gidgee Skink
The Gidgee Skink (Egernia stokesii) is a shy species of spiny-tailed skink belonging to the large Egernia genus of Australian lizards. The species is named in honour of Admiral John Lort Stokes who served with Charles Darwin on the HMS Beagle and charted the Houtman Abrolhos Islands in Western Australia, where the type specimen was first collected. The common name is derived from the species' association with Gidgee Trees (Acacia species).
This medium-sized skink has a relatively short tail with keeled scales along its dorsal surface from the back of the neck down to the tip of the pointed tail. The legs are quite short, requiring the lizard to slide on its belly when it moves around. Its colour can vary from dark brown to a rusty colour, with scattered patches of paler scales.
Snout to vent length is 195mm
Cunningham's Skink, Egernia cunninghami, Hosmer's Skink, Egernia hosmeri, Spiny-tailed Skink, Egernia depressa
The species has a widespread (though broken) distribution across semi-arid Australia, from far west New South Wales to the south-western interior of Western Australia. They are also known from several islands off the west coast of Western Australia.
The species occurs in shrubland and open woodland, and often on rock outcrops. Groups of Gidgee Skinks will shelter between rocks, split trees and logs, and within hollows.
The breeding season in the wild differs based on location; females in South Australia have been recorded giving birth between mid-summer and early autumn, however, a wild-caught female from Western Australia gave birth in mid-winter.
Feeding and Diet
These omnivorous lizards feed predominately on vegetation such as fruit and leaves in the wild, as well as any invertebrate they can catch.
The captive diet for this species at the Australian Museum is provided in three feeds within a period of a week. These consist of a small feed of chopped vegetables on one day, a small serving of kangaroo mince on another day as well two cockroaches or crickets for the third feeding. The timing and order of the diet is changed around to simulate natural conditions and prevent stereotypical behaviour (where an animal will have predicable activity patterns and essentially be waiting to be fed). This food is supplemented with calcium and vitamin powder to ensure that a nutritionally balanced diet is provided.
Other behaviours and adaptations
The species tends to defecate in the same spot, a habit that leads to little piles of scats and probably derives from the set routines of animals living in the same place for long periods. This behaviour allows a group of lizards to concentrate its scent in one location away from where they shelter, making it difficult for predators to locate home sites.
Living in large social groups makes it easier to spot danger. When threatened this lizard will take cover in a hollow log, under bark or between rocks. If harassed further it will inhale air, making its body swell up - this increased size, combined with the spiky keeled scales, makes it difficult for a predator to dislodge the lizard from its hiding place.
Life history mode
Mating and reproduction
This species is highly monogamous with most males fathering only one litter. Females are sexually mature at a snout-vent length of 171 mm and have only one litter per season.
Not all mature females produce every season. In one study, 26 percent of the females did not reproduce in one year. Litter size ranges from 1-8. Gravid females experience contractions of the body and tail for up to 40 minutes prior to the beginning of birth. The young are born head first and each young takes from 26 to 73 seconds to be born. As little as 6 seconds may separate the birth of two skinks in the same litter and a single female can take 1-12 days to give birth to all her young.
Predators, Parasites and Diseases
Gidgee skinks fall prey to dingos, cats, foxes, birds of prey, monitors and snakes.
The species is often infected with the tick Amblyomma vikirri, a species that seems to be closely associated with rock outcrops. The larvae and nymphs of the tick tend to attach in the ears and on the digits whereas the adult ticks tend to seek the posterior part of the back and the tail.
This species is protected in Australia and cannot be collected from the wild and a permit is required in most states and territories to keep this species in captivity. Please see the Resources for keeping live animals page and check with your local wildlife licensing agency.

Healthy planning policy and monitoring in Southwark and Lambeth
Built environment professionals are increasingly interested in the relationship between places and health. Many guidance documents are available to inform planning policy-makers of the importance of planning and health, yet there remains uncertainty about exactly 'what works' with regard to specific design and policy measures. In part, this has been explained by a lack of clear causal evidence to inform practice. However competing policy priorities and differing cultures of practice and evidence use across health and planning also play a role.
Despite these challenges, there is a growing desire to integrate design and planning measures which are known to support health and wellbeing into policies and projects. Planners want to know what has worked elsewhere and what evidence can be used to support local policies.
The research focused on three key health themes in Southwark and Lambeth which are widely relevant in the UK and internationally: social isolation, obesity (physical activity/healthy eating) and access to health services. Like many aspects of the urban environment's impact on health, there are many interconnections across these topic areas. The findings from academic research, consultation activities and policy examples often do not correspond to separate policy domains because of these overlaps. This is particularly notable with two of the focus areas for this review – social isolation and physical activity – which are both influenced by similar characteristics of the urban environment. In some ways, this is an advantage because policies can have multiple co-benefits. For example, increasing walkability through urban design may improve physical activity, increase social engagement and reduce local carbon emissions.
Planning policies alone will not address complex health issues like social isolation and obesity. As is often the case in urban planning and public health, officers will need to work across departments in the council and with other public and private stakeholders to integrate built environment solutions with other health promotion measures. Furthermore, solutions from one neighbourhood or research study may not be applicable more widely, depending on local context. There is great value in engaging local communities to explore their views of local problems and assets. This can ensure that policies and design measures respond to local needs, resulting in better outcomes.

 - A summit meeting is a meeting of heads of state or government, usually with considerable media exposure, tight security, and a prearranged agenda. Notable summit meetings include those of Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin during World War II. However, the term summit was not commonly used for such meetings until the Geneva Summit. During the Cold War, when American presidents joined with Soviet or Chinese counterparts for one-on-one meetings, the media labelled the event as a "summit". The post-Cold War era has produced an increase in the number of "summit" events. Nowadays, international summits are the most common expression for global governance.

Summary of Survey on Housing, Ownership, and Community Amenities Preferences
In November 2020 we received completed surveys from 38 Founder households which is 98% of all Founder households. One third of the respondent households are single-person.
Most surveyed Founder households won't be ready to move in until 2024 or later.
Our three core amenities include:
- a dance/community hall
- a dining facility/food services
- a licensed Family Care Home (Household Model)
At least two-thirds of Founder households that responded to the survey indicated that these amenities should be either in place upon move-in or within one year thereafter.
Respondents considered the following other amenities (onor off-site) essential or important (by the percentages shown):
- cultural/recreational facilities: 82%
- a licensed Skilled Nursing Facility: 66%
- access to health care with a physician or nurse practitioner and in-home assistance with activities of daily living: 50%
The survey results on housing preferences suggest a development which prioritizes semi-detached dwellings first, apartments second, and single family residences in the third phase, but also realizes that a mix of housing is important in each phase.

 The HList library
 A model of labels as needed for extensible records. As before,
 all the information about labels is recorded in their type, so
 the labels of records may be purely phantom. In general,
 Labels are exclusively type-level entities and have no run-time
 Record labels are triplets of type-level naturals, namespace,
 and description. The namespace part helps avoid confusions between
 labels from different Haskell modules. The description is
 an arbitrary nullary type constructor.
 For the sake of printing, the namespace part and the description
 are required to be the instance of Show. One must make sure that
 the show functions does not examine the value, as descr is purely phantom.
 Here's an example of the good Label description:
 data MyLabelDescr; instance Show MyLabelDescr where show _ = "descr"
 which obviously can be automated with Template Haskell.
 This model requires all labels in a record to inhabit the same namespace.
module Data.HList.Label2 where
import Data.HList.FakePrelude
import Data.HList.Record (ShowLabel(..))
-- Labels are type-level naturals
data HNat x => Label x ns desc -- labels are exclusively type-level entities
-- Construct the first label
firstLabel :: ns -> desc -> Label HZero ns desc
firstLabel = undefined
-- Construct the next label
nextLabel :: Label x ns desc -> desc' -> Label (HSucc x) ns desc'
nextLabel = undefined
-- Equality on labels (descriptions are ignored)
instance HEq x x' b
 => HEq (Label x ns desc1) (Label x' ns desc2) b
-- Show label
instance (HNat x, Show desc) => ShowLabel (Label x ns desc) where
 showLabel = show. getd
 where getd :: Label x ns desc -> desc
 getd = undefined
instance (HNat x, HNat2Integral x,Show ns) => Show (Label x ns desc) where
 show l = unwords ["L",show ((hNat2Integral x)::Integer), show ns]
 where geti :: Label x ns desc -> (x,ns) -- for the sake of Hugs
 geti = undefined

Gigantic Jawbones from the Channel Islands
Two very different races waged war on the Channel Islands. One was a race of giants whose jawbones were so large they could slip over a full-grown man's head. One of the skeletons was of a gigantic individual in which a long bone spear point was sticking out of his leg bone. His skull was shattered by a large round stone used as a war-weapon. A spear had passed through his heart dealing a death blow, it was thrown so hard it pierced through his shoulder blade. This account comes from a Mr. Long-fellow says the San Fransisco Chronicle.
The archeological establishment found a treasure trove of artifacts: skeletons (9 entire while hundreds had been burned), 87 skulls, weapons and instruments, there were ornaments and jewelry made of shell and stone on San Nicholas Island which is about 65 miles on and island off the coast of Santa Barbara, California.

Mountain Leathers are natural felts of fibrous minerals. They tend to be found on steep, wet slopes in the mountains or
along the banks of mountain streams. Common mountain leathers include felts of the asbestos minerals and fibrous clays.
Chrysotile asbestos is the fibrous form of the mineral lizardite of the serpentine group of minerals. Its chemical
formula is Mg3[Si2O5](OH)4 with some Fe2+ substituting for Mg. The amount of iron substitution affects the refractive
indices and the birefringence. This is the most common form of asbestos used commercially, comprising about 93% of all
the asbestos mined. It is also the least hazardous of the asbestos minerals. It is the most flexible of the asbestos
minerals and is the one typically used in making asbestos cloth and asbestos paper.

My understanding that if you are addressing a bishop, the correct form is "Vladyko," while if you are referring to a bishop in the third person, the form is "Vladyka." Even if they sound the same in English, we should follow the spelling conventions. So the title of this article should be changed if the definition is to remain the same. --Fr Lev 05:42, September 19, 2014 (PDT)


create a filter that limits the data to a sliding time window, such as the previous 5 days. You specify filters in Charts using an MQL Query Document. To specify a relative date query, you need to do a bit of arithmetic to create a new Date object based on the number of milliseconds relative to the current date, represented by Date(). To specify the last 5 days, use the following filter:
{ observationDate: {$gte: Date(Date() - 5 * 24 * 60 * 60 * 1000)}}
After applying the filter, you can give your chart a title and we're done!
After saving the chart, you can resize it on your dashboard, and then start to create additional charts to give you even more insight into the weather in your city.
Another Example: Home Battery Data
I chose the Weather scenario for the main example in this article as it's easy to get working and something we can all relate to. However, in practice, you can probably get a lot of this info from weather websites. The real value is not so much in this one specific example but in the pattern and its implementation using the MongoDB platform.
No matter what your interests are, chances are there are APIs that return data that is of value to you, and you can use the same approach from the weather example to ingest and visualize this data. The following screenshot shows one I created to show the status and history of my home battery storage system. You can see the storage level over the last week, the current storage level and understand how the usage changes over the seasons.
Hopefully, this will give you some ideas on dashboards that you'd like to create. Have fun exploring and visualizing your data!

Chicago recently unrolled its pedestrian safety plan, joining the ranks of cities such as Portland and New York, which have their own plans for preventing serious pedestrian accidents. The Chicago plan has 250 recommendations to prevent injuries and fatalities. Could Fort Lauderdale benefit from a similar plan? Some of the recommendations in the Chicago policy could help prevent Fort Lauderdale pedestrian accidents as well:
1) Chicanes. Chicanes are extra turns added to a roadway to slow traffic down. Since in many cases Fort Lauderdale traffic accidents are caused by speeding, reducing traffic speed can be a good way to slash the risk of accidents.
2) Pedestrian islands. In some cases, Fort Lauderdale pedestrian accidents occur because a car enters a pedestrian area. Pedestrian islands keep pedestrians separated from cars and discourage pedestrians from entering traffic.
3) Midblock curb bumpouts. These narrow portions of a street to slow traffic, usually by extending the curb. This is yet another way to reduce speed in order to help prevent Fort Lauderdale car accidents.
4) A system for repairing two high-collision areas and four dangerous intersections each year. The Chicago plan calls for authorities to find and address dangerous intersections and corridors annually. Fort Lauderdale also has high collision areas and areas that are considered especially dangerous. Identifying and rectifying these problems can help prevent traffic accidents.
5) Speed humps. Reducing speed with speed bumps is effective, according to experts, because speed bumps work whether there is enforcement or not. Most cars will slow down rather than taking speed bumps at a high speed, making them more effective than simply lowering the speed limits.
6) Pedestrian scrambles. A pedestrian scramble stops all vehicle traffic at an intersection and allows pedestrians to walk in every direction at the same time. Pedestrians can even walk diagonally. Pedestrian scrambles work because they prevent pedestrians and cars from sharing an intersection at the same time. It helps prevent Fort Lauderdale pedestrian accidents caused by cars turning into a pedestrian area.
7) Road diets. Road diets reduce the number of lanes on some roads, reducing traffic and therefore crashes. Former Florida Bicycle and Pedestrian Coordinator Dan Burden is a fan of road diets, noting that they improve road safety and may help prevent Fort Lauderdale bicycle accidents and Florida traffic accidents.
Roundabouts. These round intersections separate pedestrians from traffic entirely, by having pedestrians stay one car length outside of the intersection. When crossing this type of intersection, pedestrians only face oncoming traffic from one area and traffic is slowed down significantly in roundabouts, which could also reduce the risk of Fort Lauderdale traffic accidents.
9) An improved pedestrian network, including wayfinding systems and better walking access points to public transit. In some cases, Fort Lauderdale pedestrian accidents occur simply because pedestrians do not have safe areas to walk. For example, some neighborhoods do not have adequate sidewalks.

Abstract—Polypropylene (PP) with high thermal stability and good electrical properties, has attracted much attention for its potential to take the place of cross-link polyethylene (XLPE) as HVDC insulation because PP is more easily recycled than XLPE due to its thermoplasticity. Due to the adverse effect of electric field reversal under HVDC application, there is a need to find the new polymer insulation material with higher thermal conductivity and good electrical performance. This paper investigates the effect of introducing aluminum nitride (AlN) and magnesium oxide (MgO) into PP on the electrical properties of the resulting the new nanocomposites. In the sample preparation, AlN and MgO were surface-modified by KH570 (γ- methacryloxypropyltrimethoxy silane) and then introduced into PP by the solution method to manufacture the nanocomposite materials. The measurements made were the voltage breakdown characteristics and the DC conductivity. The results obtained show that the combination of AlN and MgO can slightly decrease the DC conductivity of PP/AlN/MgO nanocomposites compared with pure PP. The breakdown strength was slightly decreased. which shows that the adverse effect of AlN on the electrical performance of PP can be compensated by introducing MgO nanoparticles. Hence, the new polymer with high thermal conductivity and good electrical properties could be manufactured by combining two kinds of nanoparticles.

All About Bird Eggs
Many of us at the New-York Historical Society have Audubon-mania. Our new exhibition of bird watercolors by John James Audubon, Audubon's Aviary, has brought a lot of excitement to the museum's galleries. Exploring the exhibition and seeing so many beautiful paintings of birds made me wonder what their eggs look like. I know that bird eggs can be just as beautiful as their plumage—Robin Egg Blue has always been my favorite Crayola crayon color—so I was surprised to discover that very few of Audubon's bird studies in the exhibition include eggs. I was even more surprised to see that in two of the paintings, it looks as though the birds are stealing or eating other birds' eggs. In one watercolor, three blue jays appear to be ferociously devouring another bird's eggs. And in another, adult robins are feeding their young, while one adult robin towards the top of the image seems to have a white egg in its mouth.

Is egg-stealing something birds actually do? I did some research to answer this question and others I had about bird eggs.
1) Do some birds eat other birds' eggs?
Blue jays and other members of the crow family are notorious egg-stealers. They are intelligent and aggressive and will raid other birds' nests to steal eggs, young birds, and even the nest itself. So yes, the blue jays in the painting are indeed eating another bird's eggs. Audubon wrote of the blue jay, "Who could imagine that a form so graceful…should harbor so much mischief."
As for the robin, although it initially appeared to me that the bird in the above painting is eating an egg, this is not something robins are known to do. Robins' diets consist of worms, fruits and berries, and more worms. Through my research, I found another painting of robins by Aududon. In this painting, the birds are sitting on a branch and eating berries that look a lot like the round white object I originally thought was an egg in the other painting. Mystery solved. The robin was not eating an egg, but a piece of fruit.

2) What is the largest bird egg?
The ostrich egg is the largest of all bird eggs, averaging at 3.3 lbs. It's around the size of a cantaloupe.

3) Which birds lay the most colorful eggs?
There are many bird species that lay eggs with beautiful coloring. Among them are robin eggs and emu eggs, both shades of bluish green. The emu egg is also one of the world's largest, weighing in at around 2 lbs.

"Emu egg" by Shuhari, CC-BY-SA
4) Why are bird eggs different colors? Why do some have spots?
The color and markings on eggs help camouflage them to stay them hidden from predators. Sometimes the parent bird has to leave the eggs exposed in the nest, so it is important that the eggs blend into their surroundings. Birds that nest in holes in trees or places where they cannot be seen easily often lay white eggs, since they do not have to be camouflaged. Birds that nest on the ground usually lay eggs that are brown with brown or black markings so they look like the dirt and rocks in their habitats. However, scientists are still trying to come to a consensus on other reasons for egg coloring, such as why robins' eggs are blue.

Construction continues on Caldecott Tunnel 4th bore
February 7, 2011 8:06:52 PM PST
For the past five months, crews have been carving out the fourth bore of the Caldecott Tunnel. The $420 million project is still two years from completion, but crews have been working around the clock and facing some very real dangers.
For every five feet the road header carves through the East Bay hills, a thick coat of shotcrete is sprayed on the walls, bolts are drilled in for support, and another six inches of shotcrete finishes the process. It is repeated 24 hours a day.
When it is finished, the Caldecott Tunnel's fourth bore will be 4,000 feet long. But each day, the miners only advance 10-15 feet, hauling out 1,500 tons of muck.
So far, they are almost one-third of the way through and every day poses new challenges. The site is considered a "gassy" tunnel, which means something as simple as the electrostatic spark from a cell phone could turn a pocket of methane gas into a deadly fireball.
"It's all about safety; i's not an easy job, it could be dangerous if you're not smart," project superintendent Bill Monahan said.
A process called "brassing in and out" is mandatory. Brass tags indentify who is "in" and who is "out" of the bore. In the early days of tunneling, brass was used because of its high melting point of 1,700 degrees.
"In the event there is a fire, that won't melt; it'll survive the fire and the identifying imprint will still exist," project engineer Bob Smythe said.
Methane gas is also poisonous, so giant ducts constantly blast air into the tunnel.
"So if there was a pocket of methane or poisonous gas, it would be diluted before it got to the sensors," Smythe said.
As the crew tunnels through the Orinda formation and into the Claremont formation, geologists expect to find larger pockets of gas and more dangerous rock formations.
"Along the slick and slides blocks can fall down, break out of the face, and that makes it dangerous for the miners," geologist Gerhard Neuhuber said.
Neuhuber is the geologist hired to oversee the construction company's geologist. Despite the redundancy in safety measures, they had a sobering moment last November, when a large chunk of shotcrete broke off and injured two miners.
"It was about five feet long, and probably six to eight inches thick and three foot in width," Monahan said.
"They were putting the second level on there and they jumped on it too quick, well it just hadn't cured," Smythe said.
You know, you have always have to take care when you work inside a tunnel because something can happen," Neuhuber said. "You never can measure everything."
With all of his geological technology, Neuhuber says he could not have predicted the temperature's effect on the quality of shotcrete and leaking mountain water that may have loosened the shotcrete before it could dry. It is just another dangerous unknown the crews face as they mine their way through the mountain.
