Self-taught developer + B.Sc. in computer science (got me some paper to show people).
I like to dig into strange operating systems and figure out how they tick (Haiku and Plan 9 for example), which has also lead to micro-kernel and a minuscule operating system just for me.
I plan to, some day when the kids are at sleep, to develop a game engine -- I just need to figure out what I want to do with one.
