• Back-to-back ajax long poll without a recursive callback function.

  - by Teddy

  I'm trying to make long poll ajax calls, back to back. The problem with the current way I'm doing it is that I make each successive call from the callback function of the previous call. Is this a problem? Firebug doesn't show any of my ajax calls as completed, even thought the data is returned and the callback is executed. The recursive structure seems inefficient. Any ideas?

• Difference between arguments in setInterval calls

  - by Martin Janiczek

  What's the difference between these setInterval calls and which ones should be used? setInterval("myFunction()",1000) setInterval("myFunction",1000) setInterval(myFunction(),1000) setInterval(myFunction,1000) My guess is that JS uses eval() on the first two (strings) and calls the latter two directly. Also, I don't understand the difference between the calls with and without parentheses. The ones with parentheses call it directly and then periodically call its return value?

  Generate the Fibonacci sequence in the fewest amount of characters possible. Any language is OK, except for one that you define with one operator, f, which prints the Fibonacci numbers. Starting point: 25 characters in Haskell: f=0:1:zipWith(+)f(tail f)

• Understanding this matrix transposition function in Haskell

  - by dmindreader

  This matrix transposition function works, but I'm trying to understand its step by step execurtion and I don't get it. transpose:: [[a]]->[[a]] transpose ([]:_) = [] transpose x = (map head x) : transpose (map tail x) with transpose [[1,2,3],[4,5,6],[7,8,9]] it returns: [[1,4,7],[2,5,8],[3,6,9]] I don't get how the concatenation operator is working with map. It is concatenating each head of x in the same function call? How?

  I have a program which does a system call: latex somefile.latex This runs ok, when I type it directly in the command line, or when i invoke the program via CGI.

Must increase the hyph_size (Fatal format file error; I'm stymied) I already tried to increase the hyph_size but still no effect.

• Need for prefixing a function with (void)...

  - by puffadder

  Hi All, I recently came across a rather unusual coding convention wherein the call for a function returning "void" is prefixed with (void). e.g. (void) MyFunction(); Is it any different from the function call like: MyFunction(); Has it got any advantage or is it yet another needless but there coding convention of some sort?

• "IntelliTrace debugging not available" error in Visual Studio 2010

  - by Tony_Henrich

  In XP 32bit Visual Studio 2010 I get the error below when I start debugging with IntelliTrace enabled. Doesn't IntelliTrace work in Windows XP or is there some setting which causes this error? UPDATE: The error occurs when I choose the second option to add call information in the IntelliTrace settings. There's nothing in the event log about this error. The question now is how to find out why VS is having trouble adding call information.

• Reliable session faulting for unknown reason

  - by Scarfman007

  I am trying to achieve the following - one client-side proxy instance (kept open) accessed by multiple threads using a reliable session. What I have managed so far is to have either A) a reliable session with a client-side proxy which is created and disposed per call or B) what I aim for, but without a reliable session. When I enable reliable sessions on my binding however, the following behaviour is exhibited: Client-side Upon application startup everything appears to work fine until roughly 18 messages in to the WCF session. I firstly get the proxy.InnerChannel.Faulted event raised, then an exception is caught at the point where I am calling the method on the proxy. The exception is a System.TimeoutException, with message: "The request channel timed out while waiting for a reply after 00:00:59.9062512. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout." The inner exception has a similar message: "The request operation did not complete within the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout." With the method at the top of the inner stack trace being: System.ServiceModel.Channels.ReliableRequestSessionChannel.SyncRequest.WaitForReply(TimeSpan timeout) I then call proxy.Close followed by proxy.Abort (catching and ignoring exceptions). If I utilize the default settings (i.e. have simply <reliableSession/>), then calling proxy. Close results in another System.Timeout exception (although this time the allotted timeout is 00:00:00), however if I override the defaults as specified above no exception is thrown. Service-side Utilizing WCF tracing I get a System.ServiceModel.CommunicationException, with message: "The sequence has been terminated by the remote endpoint. The session has stopped waiting for a particular reply. Because of this the reliable session cannot continue. The reliable session was faulted." And a stack trace ending at: System.ServiceModel.AsyncResult.End[TAsyncResult](IAsyncResult result) When remotely attaching to the server I get the same message, which occurs when code execution steps over the return statement of my service in the service call which causes the error. The puzzling thing to me is that the service is stable and runs with options A) or B) as decribed at the beginning of my post, and occurs after a varying number of messages (around 18). The former fact points to there being nothing wrong with the code (indeed I have checked that no exceptions are thrown), and the latter just serves to confuse me and is why I modified the settings on the reliable session binding. I am quite stuck on this. Can anyone suggest why the reliable session would fault in such a way?
