I am a retired engineer, transducer
design, test equipment design, technical
ceramics, analog circuitry. I started
using time shared computers in the 1970s
and personal computers in the 1980s. My
computer programing is self-taught:
primarily Basic, APL, Forth, etc. with a
smattering of assembly and C. I have
written programs to control test
equipment and to analyze test data. Many
programs have been run once, get the
answer, quit. I did work for Microsoft
for 6 months as a temp consultant
developing hand writing recognition
algorithms but writing no production
code. The little scraps of code I wrote
to test stuff was mostly APL.
