As I'm a developer and a fervent supporter of FOSS (Free and Open Source Software), I have a couple pet projects that I actively work on:
audiopreview: play previews of your audio and video files (it can act also as a media player) in a quick and easy way using the command-line.
ųTimer: a command-line multifunction timer featuring a countdown, a regular timer, and a stopwatch.
Barok: a lightweight media player daemon. (not released yet)
Code Alpha Tools: a suite of tools built and running with open source software. So far, there is a spell checker, a french verbs conjugator, and a french verbs deconjugator.
And you are free to contact me if you wish to contribute to any of these projects.
