I am a C programmer working in the area of process control of mobile hydraulics.
Am sufficiently old to still use DOS when in doubt, and I can remember the days when it took less than 5 minutes to boot a computer.

Play with vector graphics for fun; hence Inkscape, which I think is the coolest thing since sliced bread.

Website is http://www.vaxxine.com/apenner , where I shamelessly advertise my graphics project, BezierDraw, http://launchpad.net/bezierdraw.
