Probably one of the oldest, longest practicing hackers in the world. Been programming, designing, managing programmers, and running enterprises since the days of vacuum-tubes. Can't even remember how many computers, OS's, languages, libraries, frameworks, and IDE's I've worked with. Got lucky in the PC goldmine, and have been retired since late 1980's. Still programming, though, because it's one of the most interesting, creative, and challenging things one can do. Also very frustrating.
