For the past couple of decades at least, supercomputers are decommissioned when newer HW becomes so much more power efficient that it's cheaper to buy new hardware than keeping the old one running. Usually that lifespan is in the range

I'd argue Ukraine would be better served by the ~1000 ATACMS (in service 1991-) sitting in storage with their expiration dates rapidly approaching, than by a small number of some prototype hypersonic missiles.

From what I read (on that source of all truth, twitter), SR-72 was effectively canceled due to unforeseen technical challenges. But might be that with a functional dual mode ramjet, assuming that was the major holdup, perhaps the project co

Yes, but that doesn't mean that using basic protective gear, like every heavy industry worker in developed countries, wouldn't reduce other kinds of injuries.

Even if you do nothing 'fancy' like Nagle, corking, or userspace building up the complete buffer before writing etc., at the very least the above should be using a vectored write (writev() ).

Well standard racks don't really tell anything about how power distribution is handled. So why not make the OCP rack an extension of the EIA 19" rack? As it is, it's slightly wider, and as you mention the OU is slightly diffe
