Windows Virtual PC vs. Hyper-V Virtual Machines vs. Windows Virtual PC after XPMode installation Advantages and Disadvantages

Hyper-V Virtual Machines

Advantage:

64-bit support
dynamic memory allocation
multi-core CPU
Can install Windows 7 and Windows Server 2008 and later

Disadvantage:

Can't get sound to work on those machines yet
[Updated 2011-05-05] This is disappointing, but I guess it fits most people's requirement as most people don't use Hyper-V for personal development environment. Guess I'll just have to set up those machines for remote connect.

Vim Search and Replace: The Ultimate Guide

One :%s command replaces every match in a file before a find dialog would even open. The Vim substitute patterns worth the muscle memory: flags, ranges, capture groups, and multi-file edits.
