I'm assuming it's a cylinder 500 m tall, lifted by 500 m so it almost clears the hole (assuming basalt at 2.9 g/cm^3, that's only 1.6 TWh, but close enough.) Watching a 1 km-wide 150-story structure rise from a hole and

Not OP, but at several jobs our labs were small server rooms stuffed with network gear, servers, and client PCs. They were used for end-to-end simulations and tests. It wasn't uncommon to actually do work in the lab, keeping an eye on

Don't know if this is related, but the Fed still has them under an asset cap (size limit) and reiterated in Sept. 2021 that they are not likely to get out of the doghouse anytime soon [1]. This is speculation, but it would not be supri

Nope. I remember playing lots of much more enjoyable video games from decades ago, some not much more recent than Pong (technology moved quickly). Pong was pretty much a Pet Rock novelty.

Actually, it was boring :) Yeah, our family bought one. It was novel, and we kept and played it for a while, but it really wasn't that interesting.

Watch the Mentour Pilot video; there was a display in the cockpit which showed the actual control surface movement. Why didn't they catch it? I'd guess it was because they were just a regular flight crew as opposed to acceptance t

Good technical discussion of Boom's engine situation, what their contract with Rolls Royce actually entailed. There's a conceptual fanjet candidate (not just a turbojet) that GE was developing for Aerion; it's based on an exi

Atomic ops only address a small part of the problem.* Sure, your internal queue pointers will be sane, and two-stage register settings won't be interrupted. But locks are very fine-grained, and aren't going to help you keep co-o

A stack is register renaming. Instead of "Register #n" you refer to it as "SP - n". The difference is that it's rebased with every op, and in ops the registers are almost always implied: "ADD" always loa

Done. The HP 3000 "Classic" hardware had 2 to 8 16-bit words of top-of-stack registers. There was only one CPU, so CPU-level coherence wasn't an issue. There were memory caches and sometimes multiple ALUs, that was handled by

I want to appologize for my rant about "quackish theories". While it is true that pursuit of truth and rejection of falsehood is a very grave responsibility, it is a personal responsibility. Ranting is, at best, an attempt to fo
