• How difficult is Haskell multi-threading?

  - by mvid

  I have heard that in Haskell, creating a multi-threaded application is as easy as taking a standard Haskell application and compiling it with the -threaded flag. Other cases, however, have described the use of a par command within the actual source code. What is the state of Haskell multi-threading? How easy is it to introduce into programs? Is there a good multi-threading tutorial that goes over these different commands and their uses?

• Noob Question: Wordpress Looping

  - by dclowd9901

  Can someone give me an essential Wordpress Loop and explain to me what's happening with it? I'd like to put together some templates, but I don't do well with blackboxing. In other words, I'm fully capable of writing my own CMS, but when it comes to using someone else's and its arbitrary rules, I'm completely at a loss, and I just can't get my head around the standard loop Wordpress uses. Thanks for your patient guidance.

• When are response headers created in ASP.NET web forms?

  - by Jones

  I read somewhere the you can't remove response headers once they've been added. Given that, I'm wondering where in a standard ASP.NET web forms application do response headers get added initially. For example, these: Date Fri, 23 Apr 2010 16:25:56 GMT Server Microsoft-IIS/6.0 X-Powered-By ASP.NET Cache-Control private And can I stop it from happening? Do subsequent headers override old headers? Does my question even make sense? Thanks.

  - by HumerGu

  It is possible to use CRX with VS 2010: http://stackoverflow.com/questions/1441554/can-i-use-coderush-xpress-in-visual-studio-2010 Refactor Key works.

• Objects do not retain the frame that I give then when using CGAffineTransforms with Core Animation

  - by user170030

  Hi, I'm making a game where when a card is touched, it grows so that it is focused, and when you 'let go', it goes back to its original size and place. This seems pretty standard, however, when I add cards and move the hand around to accommodate different numbers of cards, touching the card makes it go to its original place, and not to the new place. This has been stumping me for a while now Any hints would be much appreciated. Thanks !

• C# function normal return value VS out or ref argument

  - by misha-r

  Hi People, I've got a method in c# that needs to return a very large array (or any other large data structure for that matter). Is there a performance gain in using a ref or out parameter instead of the standard return value? I.e. is there any performance or other gain in using void function(sometype input, ref largearray) over largearray function(sometype input) ? Thanks in advance!
