Not bad, Alex. I recall sending Eugene a blurb on the subject more than a few months ago - still got it, Eugene? I don't... Anyway, a supercomputer... ...should cost more than a million dollars (covers lots of mktg overhead) ...should come with a small armada of analysts/CEs/salestypes (kinda like a Naval carrier group) ...should go on PM at least once a week (aka CE job security:-)) ...should always be overloaded ...should always have at least one session running "vi" on it ...almost always makes for great plumbing/air handling architectures ...and most of all, is always but always surrounded by politics, money machinations, multi-level RFQ/RFP/RFI/RFwhatevers, assorted sales/marketing bonanzas, and other generally fun and unique intrigue and/or occasional international espionage/scandal.
