Programer's Font On Windows 7

I've been looking for a font on Windows 7 that's good for scripting. The two main requirements are:

1. It has to be fixed width (monospace) (of course!);
2. It can easily let you tell the difference between a 0 (zero) and an O (as in Oops!)

There are a lot nice fonts but filtered by above two criteria and native to Windows 7, it comes down to Consolas.

2011 Microsoft Scripting Game - Advanced Leader Board

I was recently in the Scripting Guy 2011 game advanced group and placed 32nd overall. Not too bad :-) considering I didn't have enough time to finish all scripts (I've done 8 out of 10), neither did I have time to polish my scripts which costed quite a few points :-(. Nevertheless it's a great experience. I learned a lot new PowerShell techniques along the way!

Using System Namespace In Powershell

There are many cool pre-defined constants, functions, methods, and etc. in System object. One would normally learn individual ones through sample scripts, but really should browse the MSDN page to explore what System namespace has to offer. Go to a class/structure/enumeration that you are interested, then pay special attention to those static members.

A few examples:

[System.DateTime]::Today  versus [System.DateTime]::Now
[System.String]::Empty
[System.Console]:: almost everything are static, not surprisingly
[System.Math]::PI

There are also a bunch of other namespaces, please see .Net Framework Libraries
