I was sad to hear earlier in the week that John Conway had died on 11 April 2020 a victim of Coronavirus.
I never met John Conway but the “Game of Life” was the first meaningful program I wrote in VSAPL at the beginning of my IT career. At the time I was a trainee Systems Analyst in a COBOL environment where my manager had the view that an analyst at a keyboard was wasting their time. Getting sent on a couple of APL courses run by IBM was a lucky diversion.
But then what was I to do with it?
John Conway’s “Game of Life” not only provided the much needed challenge but I feel also changed my life. Within a few weeks of achieving an animated solution running on a dumb mainframe terminal, I had gained enough confidence in handling arrays to switch jobs from Systems Analyst to APL Developer. That was thirty-five years ago so thank you John.
