Here are the main open source software projects I have been involved in.

b2evolution

b2evolution is a blog/content & comunity management system. There is also an unofficial blog for it ;)

Stut-One

Stut-One is server software for the French Minitel. This actually pre-dates the Internet as we know it. It was a time where being online meant black and white text displays and paying quite high fees by the minute!
