• * Bash Script Beautifier – I wrote a Ruby beautifier script a few years ago and it has become very popular. I decided to rework it to beautify Bash scripts, even though I realized that Bash shell scripts are much more free-form than Ruby programs. This project is the result — a Bash script beautifier written in Ruby.

  I have tested the script on a lot of typical Linx scripts, both my own and from the system. While testing I have reluctantly come to the conclusion that there are too many perverse ways people write Bash scripts for this program to ever correctly beautify 100% of submitted scripts. Maybe 99%, but never 100%.

• Disk2vhd – Disk2vhd is a utility that creates VHD (Virtual Hard Disk – Microsoft’s Virtual Machine disk format) versions of physical disks for use in Microsoft Virtual PC or Microsoft Hyper-V virtual machines (VMs). The difference between Disk2vhd and other physical-to-virtual tools is that you can run Disk2vhd on a system that’s online. Disk2vhd uses Windows’ Volume Snapshot capability, introduced in Windows XP, to create consistent point-in-time snapshots of the volumes you want to include in a conversion. You can even have Disk2vhd create the VHDs on local volumes, even ones being converted (though performance is better when the VHD is on a disk different than ones being converted).
