I've been programming since 1966 (grade 9 student).
PNPOLY, a little program that I wrote in 1970, is still used. I get a couple of emails a year about it. It tests whether a point is in a polygon. Translated from Fortran II to C, it's 8 lines of executable code. The documentation is about 10x longer, but people still get it wrong. https://wrf.ecse.rpi.edu//Rese...
Now I'm inventing very fast parallel geometry algorithms, teaching computer engineering, and just graduated my 18th PhD student. My code is generally freely available for nonprofit research and education, see https://wrf.ecse.rpi.edu/nikol...
HW I have used (at least a little):
DEC PDP 1, 8, 10, 11, Vax 11/780; IBM 1620, 7094, 360, 370, 5100; Prime; Lisp Machine; Motorola 6811, 68000, 68010, 68020; Sequent Balance; CM-2; Intel 8051, 8086, Pentium, Xeon; Sun Sparc; AMD Opteron.
Wordlengths: 8, 12, 16, 32, 36 (containing 5 7-bit chars plus 1 spare bit)
