  - by mongeta

  Hello, I'm testing my App and in a very simple view, each time a tap on a UITableView row, my allocation overall bytes get higher and higher and never go downs. I don't have any special code there, so I created a new project from scratch with a very simple view, force one section and just three rows. In the didSelectRowAtIndexPath code do nothing, and fire it with instruments and memory allocation and, the memory goes up with every cell selection ... Is this normal behaviour ? thanks, regards, m.

• why does Visual Studio not enforce try-catch-block implementation?

  - by Pedro

  Coming from Eclipse/Java, I noticed that in VisualStudio/C# it is not mandatory to care about Exceptions. While Eclipse forces the user to implement a try-catch-block or to add a throws declaration, this is not the case in Visual Studio. What is the reason Visual Studio doesn't inform about unhandled exceptions? Can I configure Visual Studio to force me to implement try-catch-blocks, or at least add a compiler-warning?

• Reopening serial port fails if not closed properly with CloseHandle

  - by superg

  I am working with USB device on Windows that is seen as a virtual serial port. I can communicate with the device using CreateFile and ReadFile functions, but in some cases my application does not call CloseHandle (when my application in development crashes). After that all calls to CreateFile fail (ERROR_ACCESS_DENIED), and the only solution is to log in to my computer again. Is there any way to force closing the open handle (or reopening) programmatically?

• Can someone explain this 'double negative' trick?

  - by ProfessionalAmateur

  Hello, I am by no means an expert at javascript, but I have been reading Dave Pilgrim's "Dive into HTML5" webpage and he mentioned something that I would like a better understanding of. He states: "Finally, you use the double-negative trick to force the result to a Boolean value (true or false)." function supports_canvas() { return !!document.createElement('canvas').getContext; } If anyone can explain this a little better I would appreciate it!

• How to make slider labels clickable [Flex 3]

  - by Mark Ingram

  I have a simple slider, with only 3 options. It seems strange to force the user to drag the small thumbnail on the slider, when it would be a lot easier to click one of the 3 actual labels by the side of the slider. Does anyone know how to accomplish this?

• Testing code that uses SoftReference<T>

  - by bmargulies

  To get any code with SoftReference<T> to be fully tested, one must come up with some way to test the 'yup, it's been nulled' case. One might more or less mock this by using a 'for-test' code path to force the reference to be null, but that won't manage the queue exactly as the GC does. I wonder if anyone out can share experience in setting up a repeatable, controlled, environment, in which the GC is, in fact, provoked into collecting and nulling?

• Is there a gentle way of stopping processes using Windows PowerShell?

  - by Charles Anderson

  I have to stop a browser from a PowerShell script, which I do by piping it into Stop-Process -Force However, this is very abrupt. When the browser is restarted, it detects that it didn't shut down cleanly, and tries to restart the previous session. Is there some way I can tell it to shut itself down gracefully? ("There are two ways we can do this ...")

• java api design - NULL or Exception

  - by srini.venigalla

  Is it better to return a null value or throw an exception from an API method? Returning a null requires ugly null checks all over, and cause a major quality problem if the return is not checked. Throwing an exception forces the user to code for the faulty condition, but since Java exceptions bubble up and force the caller code to handle them, in general, using custom exceptions may be a bad idea (specifically in java). Any sound and practical advice?

• What is an efficient way to find a non-colliding rectangle nearest to a location

  - by hyn

  For a 2D game I am working on, I am using y axis sorting in a simple rectangle-based collision detection. This is working fine, and now I want to find the nearest empty rectangle at a given location with a given size, efficiently. How can I do this? Is there an algorithm? I could think of a simple brute force grid test (with each grid the size of the empty space we're looking for) but obviously this is slow and not even a complete test.

• Selecting only the first item of an xpath result set in PHP

  - by IkimashoZ

  I am currently achieving the desired outcome with two PHP statements: $thisBlarg = $xmlResource->xpath('//blarg[@ID='.$someBlargID.']'); echo $thisBlarg[0]->name; But, not wanting to settle for second best, I'd really prefer this to be one statement, but PHP doesn't like this: echo $xmlResource->xpath('//blarg[@ID='.$someBlargID.']')[0]->name; And for good reason. But I can't find a way to force an xpath query to return the result directly. Any suggestions?
