• What JS framework offers scroll functionality (+animation) in a div without a scrollbar?

  - by montooner

  All: I want to scroll through a sequence of tumblr/twitter posts as a long sequence of texts. Let's say we have: <div id="mainContent"> _some content_ </div> where the css for mainContent is: #mainContent { padding: 20px 20px; background: #FFF; height:500px; overflow:hidden; } I really like the functionality of Scrollable jQuery, but they require pagination and an array of elements. I'm looking for tips in any of these categories: a js framework I can use to achieve this a solution to paginating the text

• ArrayBlockingQueue - How to "interrupt" a thread that is wating on .take() method

  - by bernhard

  I use an ArrayBlockingQueue in my code. Clients will wait untill an element becomes available: myBlockingQueue.take(); How can I "shutdown" my service in case no elements are present in the queue and the take() ist wating indefenitely for an element to become available? This method throws an InterruptedException. My question is, how can I "evoke" an Interrupted Exception so that take() will quit? (I also tought about notify(), but it seems I doesnt help here..) I know I could insert an special "EOF/QUIT" marker Element but is this really the only solution? UPDATE (regarding the comment, that points to another question with two solutions: one mentioned above using a "Poisoning Pill Object" and the second one is Thread.interrupt(): The myBlockingQueue.take() is used NOT in a Thread (extending Thread) but rather implements Runnable. It seems a Runnable does not provide the .interrupt() method? How could I interrupt the Runnable? Million Thanks Bernhard

• Slow Speeds when unzipping with PHP onto a NFS, how can I speed it up?

  - by bunwich

  Hi, I'm trying to figure out how to boost my NFS speed and php uploads. File is uploaded to the webserver's local tmp dir With PHP I copy the file userxxx.zip to the NFS With PHP I extract the userxxx.zip on the NFS to another dir on the NFS. What I'm finding is the file is in Step 3, the file is being read through the NFS by the web server, processed by the web server, and uploaded back across the NFS. Speeds as expected are very slow. Might a possible solution be to get the Fileserver to extract the zip? a) Webserver copies the file to the NFS b) Webserver makes a web service call to the Fileserver c) Fileserver can now unzip the file like it's local and the speeds should be much faster. I would appreciate any suggestion anyone how people have approached this problem. (I'm aware that php ZipArchive() is very slow, and I'll likely use java or php exec unzip to speed it up) Thanks

• Conceptual question about NSAutoreleasePools

  - by ryyst

  In my Cocoa program, wouldn't a really simple way of dealing with autoreleased objects be to just create a timer object inside the app delegate that calls the following method e.g. every 10 seconds: if (pool) { // Release & drain the current pool to free the memory. [pool release]; } // Create a new pool. pool = [[NSAutoreleasePool alloc] init]; The only problems I can imagine are: 1) If the above code runs in a separate thread, an object might get autoreleased between the release call to the old pool and the creation of the new pool - that seems highly unlikely though. 2) It's obviously not that efficient, because the pool might get released if there's nothing in it. Likewise, in the 10 second gap, many many objects might be autoreleased, causing the pool to grow a lot. Still, the above solution seems pretty suitable to small and simple projects. Why doesn't anybody use it? What's the best practice of using NSAutoreleasePools?

• Is my natural deduction proof correct?

  - by Danny King

  Hello, Given the sequent: |- p v ¬p (that is, no left-hand-side, derives p or not p) I have taken this from http://www.danielclemente.com/logica/dn.en-node38.html but I got a different proof to his solution. I think my simpler proof is correct but could someone verify it for me to check I have understood it? I'd appreciate it very much! 1. ¬(p v ¬p) assumption {note this is equivalent to ¬p ^ p} 2. ¬p ^elimination 1 3. p ^elimination 1 4. contradiction ¬elimination 3, 2 5. p v ¬p ¬introduction 1-4 Thanks!

• Making form submissions unique using PHP and HTML

  - by canadiancreed

  Hello all I'm currently developing a page where the user fills out a form, and when submitted they are taken to the next page. When on the next page, I want to have it so that if the user went back to the previous page using the back button, or hit refresh, the submission will not be saved into the DB. Now I recall reading somewhere that if you had a way to make each submission unique, this issue is averted, but after screwing around for hours on end, for the life of me I cannot recall how this could be done (using PHP), so long story short has anyone ran into this, and if so, what was your solution?

• How to impose maxlength on textArea in HTML , Javascript

  - by Rakesh Juyal

  I would like to have some functionality by which if i write <textarea maxlength="50"></textarea> <textarea maxlength="150"></textarea> <textarea maxlength="250"></textarea> it will automatically impose the maxlength on the textArea. If possible please donot provide the solution in JQuery. Note: This can be done if i do something like this: <textarea onkeypress="return imposeMaxLength(event, this, 110);" rows="4" cols="50"> function imposeMaxLength(Event, Object, MaxLen) { return (Object.value.length <= MaxLen)||(Event.keyCode == 8 ||Event.keyCode==46||(Event.keyCode>=35&&Event.keyCode<=40)) } copied from another thread But the point is I don't want to write onKeyPress and onKeyUp every time i declare a textArea.

• JSF and Ajax4JSF on WebSphere 6.1 --> Problem with Form Submission

  - by Shamik

  Has anyone setup JSF1.1 with Ajax4JSF on websphere 6.1 ? I followed the instructions as mentioned in the developer guide . The problem that I am facing is that once I use a4j:support on any of my h:inputText item, the form values are not getting set in the backing bean on the submission of the form. I do have <h:messages> tag present just above the form so that all the problems should be reported there but I do not see any error message once I submit the form. But I do see that the values are not getting set. I need to find the solution as early as possible otherwise I probably have to throw the ajax4jsf framework and write javascripts instead :(

• How to auto-include all headers in directory

  - by JRL

  I'm going through exercises of a C++ book. For each exercise I want to minimize the boilerplate code I have to write. I've set up my project a certain way but it doesn't seem right, and requires too many changes. Right now I have a single main.cpp file with the following: #include "e0614.h" int main() { E0614 ex; ex.solve(); } Each time I create a new class from an exercise, I have to come and modify this file to change the name of the included header as well as the class i'm instantiating. So my questions are: Can I include all headers in the directory so at least I don't have to change the #include line? Better yet, can I rewrite my solution so that I don't even have to touch main.cpp, without having one file with all the code for every exercise in it?

• How to easily pass a very long string to a worker process under Windows?

  - by sharptooth

  My native C++ Win32 program spawns a worker process and needs to pass a huge configuration string to it. Currently it just passes the string as a command line to CreateProcess(). The problem is the string is getting longer and now it doesn't fit into the 32K characters limitation imposed by Windows. Of course I could do something like complicating the worker process start - I use the RPC server in it anyway and I could introduce an RPC request for passing the configuration string, but this will require a lot of changes and make the solution not so reliable. Saving the data into a file for passing is also not very elegant - the file could be left on the filesystem and become garbage. What other simple ways are there for passing long strings to a worker process started by my program on Windows?

• Cannot run 32bit compiled WPF applications on Windows 7 64bit

  - by adriaanp

  I created a WPF project in VS2008 and compiled it with Any CPU, x64 and x86. Any CPU and x64 works, but compiling to x86 the application is hanging when running through VS2008 and crashing when running without debugging. Debugging it with WinDbg I can see a StackOverflowException and sometimes a MissingMethodException relating to WPF methods. Common sense is telling something here that the CLR is not loading the correct assemblies or something when running 32bit WPF apps. I tried reinstalling .NET Framework 3.5 SP1, but it does not fix the problem. I don't know how to go about checking if the correct assemblies are loaded or used. Any ideas? UPDATE: Not a real solution but the best I could do quickly was to reinstall Windows 7

• Check if a php script is running

  - by Nirmal

  I have a script that listens to a jabber server and responds accordingly. Though it's not supposed to stop, last night it did. Now I want to run a cron job every minute to check if the script is running, and start it if not. The question is, how do I check if a particular script is still running? Some solutions have been posted here, but those are all for Linux, while I am looking for a Windows solution. Any ideas please? Thanks.

• What is the easiest way to add some simple blog functionality to my website?

  - by Eric

  I've got a website, already hosted, and I'd like to add a blog section to it. However, I'm running out of time, so am looking for a quick and dirty solution. Ideally, I'd like to use something like blogger or wordpress and integrate it into my site, rather than starting from scratch. Is this easy to do? Or would it be simpler to grab the RSS feed from a blog hosted on that site, and render it with XSLT? Can anyone give me some suggestions on the easiest way to include this?

• steps for facebook connect graph api

  - by dskanth

  Hi, iam using facebook connect in my site, and i want to know how do i use the graph api for authenticating the user. I followed these steps: 1) Initially i sent a request for "code", by clicking on the facebook icon in my site: https://graph.facebook.com/oauth/authorize? client_id=xxx&redirect_uri=http://xxxxxxxx 2) And then after getting a code, i sent a request for "access token", by clicking on another link in my site: https://graph.facebook.com/oauth/access_token? client_id=xxx&redirect_uri=http://xxxxxxx&client_secret=xxxx&code=xxxxx 3) And after i got the token, i sent another request for getting user data, by clicking on yet another link: https://graph.facebook.com/me?access_token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Then finally i got the user data in array format, which i need to parse for my required data like user's firstname, email, etc. Now my question is that how i can automate this process with just one click ? Right now, iam using 3 different links for sending those requests. Can anyone suggest a solution ?

  - by AndreMiranda

  Hi! I have to dynamically send a flashvars value from <object>/<embed>, for example "<object name="flashvars" value="test=myxml.xml"> to my swf file. And in my AS, I have this: var xmlPath:String = _level0.test; doc.load(xmlPath); So, this way I want to read several xml files (at least it's my intention!). But nothing of what I do works... I also tried doc.load(_root.test) but it didnt work too. If I do: doc.load("someXML.xml") It works just fine!! I'm trying to solve this for many many hours and still didn't find any solution!! Thanks in advance!!!

• How can I pass a Visual Studio project's assembly version to another project for use in a post-build

  - by Coder7862396

  I have a solution with 2 projects: My Application 1.2.54 (C# WinForms) My Application Setup 1.0.0.0 (WiX Setup) I would like to add a post-build event to the WiX Setup project to run a batch file and pass it a command line parameter of My Application's assembly version number. The code may look something like this: CALL MyBatchFile.bat "$(fileVersion.ProductVersion($(var.My Application.TargetPath)))" But this results in the following error: Unhandled Exception:The expression """.My Application" cannot be evaluated. Method 'System.String.My Application' not found. C:\My Application\My Application Setup\My Application Setup.wixproj Error: The expression """.My Application" cannot be evaluated. Method 'System.String.My Application' not found. C:\My Application\My Application Setup\My Application Setup.wixproj I would like to be able to pass "1.2.54" to MyBatchFile.bat somehow.

• ASP.NET MVC: dealing with Version field.

  - by alex2k8

  I have a versioned model: public class VersionedModel { public Binary Version { get; set; } } Rendered using <%= Html.Hidden("Version") %> it gives: <input id="Version" name="Version" type="hidden" value="&quot;AQID&quot;" /> that looks a bit strange. Any way, when the form submitted, the Version field is always null. public ActionResult VersionedUpdate(VersionedModel data) { ... } How can I pass Version over the wire? EDIT: A naive solution is: public ActionResult VersionedUpdate(VersionedModel data) { data.Version = GetBinaryValue("Version"); } private Binary GetBinaryValue(string name) { return new Binary(Convert.FromBase64String(this.Request[name].Replace("\"", ""))); }

• Two BlockingQueue in the same endless loop?

  - by DrDol

  I have a thread, that processes incomming messages (endless loop). For this, I use a BlockingQueue (Java), which works as quite nice. Now, I want to add a second processor in the same Class oder method. The problem now is, that in the endless loop i have this part newIncomming = this.incommingProcessing.take(); This part blocks if the Queue is empty. I'm looking for a solution to process to queues in the same class. The second queue can only processed, it some data is coming in for the first Queue. Is there a way to handle tow blocking queues in the same endless loop?

• Accessing mapped network drive from ColdFusion

  - by Kip

  I am having a problem accessing a mapped drive in ColdFusion. I have \\server\files\sharing mapped to z:\. If I run this code, it says the directory exists for the full path but not for the mapped one: <cfscript> fullPath = "\\server\files\sharing\reports"; mappedPath = "z:\reports"; WriteOutput("fullPath exists: #DirectoryExists(fullPath)#<br/>"); //YES WriteOutput("mappedPath exists: #DirectoryExists(mappedPath)#"); //NO </cfscript> I have done some Googling and have found a few people with the same problem, but the solution was always to use the full path. Is there a reason ColdFusion wouldn't be able to see or access the mapped drive? And if so, are there any workarounds (maybe a system call to get the full path of the mapped drive)?

• WebSocket support on mobile devices

  - by Marco W.

  For an Android multiplayer game's communication between players I'm using a WebSocket server and TooTallNate's Java library on the client side to enable WebSocket support in the Android app. So just to point it out clearly, WebSocket support in mobile browsers is not important to me. Unfortunately, users report that they're experiencing problems such as connection failures or unreceived messages. Is that a general problem of WebSockets on mobile devices (blocked ports, firewalls, mobile Internet connection) or is that probably a flaw in the client side code? Do you have experience with WebSocket client libraries such as the one above? I've just discovered autobahn.ws for Android - but I don't know if it's worth switching from my current library (see above). What about WAMP? Is WebSocket technology not exactly the adequate solution so that I should use the sub-protocol (?) WAMP?
