I Just discovered PowerGui an application, where you can host your most used powershell scripts.
It can off course be used by IT Pros, but developers can leverage on it as well.
For instance a testing framework has been made.
I have for instance made two small scripts that searches the Eventlog to find when the computer was started and stopped during the last month. I use this when I have to register how much time was used on a project - well i have to since I am always behind here :-(
