• Match Regex across newlines?

  - by Jörg Battermann

  I have a regex ( "(&lt;lof&lt;).*?(&gt;&gt;)" ) that works and matches perfectly on single line input. However, if the input contains newlines between the two () parts it does not match at all. What's the best way to ignore any newlines at all in that case?

• Why AVCaptureSession output a wrong orientation?

  - by Peter

  Hey guys, So, I followed Apple's instructions to capture video session using AVCaptureSession: http://developer.apple.com/iphone/library/qa/qa2010/qa1702.html. One problem I'm facing is that even though the orientation of the camera / iphone device is vertical (and the AVCaptureVideoPreviewLayer shows a vertical camera stream), the output image seems to be in the landscape mode. I checked the width and height of imageBuffer inside imageFromSampleBuffer: of the sample code, and I got 640px and 480px respectively. Does anyone know why this's the case? Thanks!

• Object serialization practical uses?

  - by nash

  How many software projects have you worked on used object serialization? I personally never came across a scenario where object serialization was used. One use case i can think of is, a server software storing objects to disk to save memory. Are there other types of software where object serialization is essential or preferred over a database?

• How to abort shutdown in Windows (XP|Vista) programatically?

  - by Piskvor

  I want to be able to detect and abort OS shutdown from my application, preferably by using the Windows API. I know that it is possible to do this manually using the command shutdown -a In the worst case, I could ShellExecute this, but I was wondering if there was a better way. Also, how do I find out programatically that the OS is about to shut down, via the Win32 API?

• How to get the name of a class without the package?

  - by Ola Herrdahl

  In C# we have Type.FullName and Type.Name for getting the name of a type (class in this case) with or without the namespace (package in java-world). What is the java equivalent to Type.Name? Clearly there must be a better way than using Class.getName() and strip it of the package name manually.

• Non-Standard widget size for Android

  - by heorling

  I have a use-case for a vertical 1x4 home screen widget on android. The supported size is 4x1 ie horizontal. Does anyone know if the vertical version can be implemented? I realize changing screen orientation would scrunch the widget together, which I'm fine with. Even better would be if there was an equivalent to "overflow hidden" in css. Has anyone come across a way to do this?

• Intel AVX intrinsics: any compatibility library out?

  - by ~buratinas

  Are there any Intel AVX intrinsics library out? I'm looking for something similar as 'sse2mmx.h' header which fall-backs to MMX intrinsics if SSE2 integer intrinsics are not available on compile time. Thus if I had similar library for AVX I could write optimized code for new hardware which would have almost optimal speed in case AVX extension isn't available. Googling didn't help much so far :(

• Switch statements: do you need the last break? (Javascript mainly)

  - by Jon Raasch

  When using a switch() statement, you add break; in between separate case: declarations. But what about the last one? Normally I just leave it off, but I'm wondering if this has some performance implication I'm not thinking about? I've been wondering about this for a while and don't see it asked elsewhere on Stack-O, but sorry if I missed it. I'm mainly asking this question regarding Javascript, although I'm guessing the answer will apply to all switch() statements.

• Providing raw MP3/AAC data to Flex/Flash from a custom container

  - by Joonas Trussmann

  Having had a quick look at the Flex docs I can't seem to find any reference to providing audio content to be played from a custom (possibly encrypted - don't worry, it's not that evil) container format. Is this possible and if so, could someone point me in the right direction. Or if that's not possible, some way to hook into the disk/network (disk is much more important in this case) I/O of the sound playing mechanism to provide a supported container in memory from a custom wrapper.
