oh wow. I am truly profoundly sorry, for you and for his family. to be sure he created a bit of immortality through his work, but that is little comfort in this moment. Karen On Sat, 16 Jan 2021, D. Hugh Redelmeier via talk wrote:
David Tilbrook passed away in the night yesterday. COVID-19, dammit.
David had given a couple of talks at GTALUG.
He was a long-time UNIX guy. We did CS degrees at the same time at the University of Toronto. He was an official member of DGP (I was only a guest) where (and when) the first U of T UNIX system was installed.
We and Rob Pike worked on text editors (ed, qed), among other things.
You know when a GUI interface changes the cursor symbol to indicate that the system is busy? He invented that.
He was one of the founders of HCR, a Toronto UNIX software house.
He did a lot of interesting things, knew a lot of interesting people, and had a lot of interesting stories. He has a good family too.
I miss him. In fact, I've missed him for a year -- we were planning to visit when COVID showed up. "We" included Christopher Browne, now also passed. --- Post to this mailing list talk@gtalug.org Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
