git-repository
The source code from my PhD. thesis is available at github.
Mensa-Script
A mensa script is available that prints the menu of our student cafeterias on the console. You need Python (2.5.2 or newer) installed. It has been tested on Arch linux, Debian, Windows 7 and MAC OS X Lion.
Download by clicking the link above, then type into a unix console
chmod +x mensa.py
./mensa.py -h
The first command sets the execution flag, the latter runs the script's help for further reading.
URL Shortener
When copying links from google search results page, the URLs often contain bloat from google. IndustryStandardSoftware provides an URL-shortener. Or just disable javascript (always a good idea).
LaTeX Symbols
A nice tool if you don't know the correct LaTeX-command for a (mathematical) symbol can be found at kirelabs.org.
