The Open Source projects I've contributed to so far :-)

• The CORAS Tool - a tool for security risk analysis, being developed as part of my work at SINTEF
• KORBit - our crazy project to force the Orbit CORBA ORB into the Linux kernel, to many kernel developers' despair ;^)
• eXist XML database - various bugfixes
• JaxMe2 - bugfix for XML unmarshalling
• XDoclet - bugfix for handling of EJB relations when using BMP
• LiViD - various minor projects: mga_vid (ported to Matrox Millennium G200), mpeg2dec (MMX optimizations), spudec (subtitles), etc.
• Grip - added support for Ogg/Vorbis encoding
• Linux kernel 2.4.0 - three-line patch to fix DVD reading bug ;-)
