I am a computer security researcher, software engineer, and free culture advocate. All the software and music available here is free as in freedom. I welcome donations.
From here you may be interested in looking at:
FBAC-LSM, an experimental security enhancement for Linux, which protects you from your own programs. Usability is a primary goal.
SortTV, a script for sorting your media files. Automatically sorts and renames episodes for your home theatre PC (HTPC). Lots of features. A number of people have contributed code (thanks).
Open educational resources for learning computer security and ethical hacking.
My YouTube Channel. With various videos and presentations.
