You can find here a list of script, mostly in bash, that I have created for my personal use. They are scripts for my desktop and laptop, and are all for (Ubuntu) Linux. They may be useful to you...
Thinkpad anti-theft system
A cool script which explains how to set up an alarm system for Thinkpad laptops, using the laptop's accelerometer, hdaps and python.
Spamassassin remote filtering and KMail
Using tmpfs with Firefox
A solution to store Firefox's profile in RAM in order to speed up browsing experience.
You want to reset Google search results to be from google.com when searching from a non-US IP, and not from the local Google site? See a solution here.
aMule remote monitoring
And another bash script to monitoring aMule remotely.
OzForces usage meter
A little script to check your usage (upload and download) if your ADSL provider is OzForces (Australia).
Note that I offer no warranty whatsoever for these scripts, and some of them may be quite old by now. Use at your own risk!
