Dave Olson and John Mashey were fairly influential in terms of IRIX, and they both used to post a lot on Usenet. Also Alexis Cousin with SGI Belgium used to answer a lot of queries on Usenet. Their postings all pretty much stop around the time of the SGI Wintel and Linux transitions. Presumably they saw what was on the horizon
Sorry to drag this up, but I was - completely independently - wondering whether Alexis Cousein was still around. It seems he is, still in Belgium, just with his job title increased slightly from "Senior Systems Engineer" to "Senior Systems Engineer / Solutions Architect".
He still posts on a few Unix & Linux forums. I always did wonder about his abrupt departure from comp.sys.sgi.* but I'm afraid it seems a little unfair to just email / call him and ask
According to his site
, Dave Olson left SGI in 99, which would be rather a lot earlier than Alexis' withdrawl. Actually, well worth a quick read of Dave's site for all sorts of reasons.
John Mashey left SGI in 2000.
