• Is there a way to make sure a background process spawned by my program is killed when my process ter

  - by Davy8

• Better why of looping to detect change.

  - by Dremation

  As of now I'm using a while(true) method to detect changes in memory. The problem with this is it's kill the applications performance.

• How can I make PowerShell run the original Start-Process cmdlet rather than the PSCX Start-Process c

  I have PowerShell v2.0 installed and on top of that, PSCX is installed. PSCX is the PowerShell Community Extensions (http://pscx.codeplex.com/Wikipage). It seems that I have two cmdlets called Start-Process installed and I'm guessing one is the original and the other is from PSCX. When I invoke Start-Process, the PSCX cmdlet is…

• A method to change effective user id of a running program?

  - by Brendan Long

  I'm writing a simple package manager and I'd like to automatically try sudo if the program isn't run as root.

So far all I can think of is a bash script to check before they get to the actual…
