Currently working on LTSP for Revolution Linux. I'm one of the leaders of the Edubuntu project and an Ubuntu Core Developer.
I'm also part of the Ubuntu QA team and member of different other teams and boards as part of the Ubuntu project.
I'm mostly coding in Python, PHP, shell scripts (POSIX) and C.
I also have some (old) knowledges of perl and C++.
