Software developer, professional since the early 90s, amateur back to the mid 80s.

First touched a Unix box in 1989 or 1990. First got paid to do so in 1993.

Pixel pusher for fun, mostly photography, but some 3D (my avatar is one of my pieces) and 2D art.

comment Why can't ed be exited with C-c?
@Gilles: One of the side effects of calling error(s) in ed.c is to return to the main processing loop. It does so with a longjmp() call. shudder
