California, Ireland, Colorado.
MS Math/CompSci UCLA.
Locus, Sun Microsystems; PDP-11, x86, C, Go.
Programming since 1973.
I wrote the program that calculated the GPA that appears on my high-school transcript.
Starting in 1984 I led the project at Locus to create the first x86 virtual machine, to run MS-DOS under Unix, on the AT&T 6300 Plus (
https://en.wikipedia.org/wiki/6300_Plus).
The lines in the avatar are horizontal.
There should be no profit in human misery.
