• PowerShell - Shorten namespace names so it's easier to access types

  - by Adam Driscoll

  Is there a method of shortening PowerShell namespace references? Typing [RootNameSpace1.NameSpace2.Namepsace3+SomeEnum]::SomeValue is taxing and not a very good user expierence. I realize that you can reference System level objects without a namespace such that [Type]::GetType(... will work. Is there some manifest I could create or command I could use to shorten lengthy namespaces?

• c++ FFT Beat detection library?

  - by mokaschitta

  Hi, I am currently looking around for a good allround beat detection library / source code in C++ since I found it really hard to achieve satisfying results with the beat detection code I wrote myself using this tutorial: http://www.gamedev.net/reference/programming/features/beatdetection/ It's especially really hard if you want to make it work with any kind of music so I was wondering if there is something usable out there allready? Thanks!

• COM Interop error, class not registered when using MSMQ Library

  - by mattmck

  I've referenced the MSMQ v3 Object Library in a VS2010 C# project only to get: System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {0188401C-247A-4FED-99C6-BF14119D7055} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)). I've registered the library the reference points to: regsvr32 C:\windows\system32\mqoa.dll What am I missing?

• When to use weak references in Python?

  - by bodacydo

  Can anyone explain usage of weak references? The documentation doesn't explain it precisely, it just says that the GC can destroy the object linked to via a weak reference at any time. Then what's the point of having an object that can disappear at any time? What if I need to use it right after it disappeared? Can you please explain them with some good examples? Thanks, Boda Cydo.

• Regex to Match White Space or End of String

  - by Kirk

  I'm trying to find every instance of @username in comment text and replace it with a link. Here's my PHP so far: $comment = preg_replace('/@(.+?)\s/', '<a href="/users/${1}/">@${1}</a> ', $comment); The only problem is the regex is dependent upon there being whitespace after the @username reference. Can anyone help me tweak this so it will also match if it is at the end of the string?

• EF OrderBy method doesn't work with joins

  Following works (ordered by name): from t in context.Table1.OrderBy( "it.Name" ) select t This doesn't work (no ordering): from t in context.Table1.OrderBy( "it.Name" ) join t2 in context.Table2 on t.SomeId equals t2.SomeId select t Nor does this (trying to reference the parent table to order): from t in context.Table1 join t2 in context.Table2.OrderBy( "it.Table1.Name" ) on t.SomeId equals t2.SomeId select t Nor does this (trying to order on the child table): from t in context.Table1 join t2 in context.Table2.OrderBy( "it.ChildName" ) on t.SomeId equals t2.SomeId select t How do I cause OrderBy not to be ignored while joining?

• MPMoviePlayerController doesn't implement MPMediaPlayback protocol as advertised?

  - by goren

  I'm trying to use the MPMediaPlayback protocol's currentPlaybackRate() to slow down a video. I'm confused though as the class MPMoviePlayerController states that: You can control most aspects of playback programmatically using the methods and properties of the MPMediaPlayback protocol, to which this class conforms. Except just above in the header here: http://developer.apple.com/iphone/library/documentation/MediaPlayer/Reference/MPMoviePlayerController_Class/MPMoviePlayerController/MPMoviePlayerController.html it doesn't seem to. All I want to do is slow down the playback rate for a video.
