Here you can find in no particular order a list of Open Source software projects and applications I have participated to.
Most of the projects I currently work on are currently hosted at Github:
Older, mostly legacy Open Source projects can also be found at SourceForge and projects-legacy.ez.no.
I sometimes publish short code snippets on Gist.
Last but not least, this website hosts a public XML-RPC Debugger and Demo Server.
