I contributed to some open source projects by submitting patches. Not all of my patches where accepted -- however, I uploaded some patches to a directory (including accepted patches): See most patches (does not include documentation patches or other unimportant contributions).

Some useful patches:

• OpenBSD psig: port Solaris' psig to OpenBSD (rejected)
