That's "Sign EXtension" for the those wondering about that. The A and B registers combined to be the 16-bit D register, and this instruction would be used to convert an 8-bit signed integer to 16-bit. Also amusing was the &q

The most useful aspects of the financial industry are the most heavily regulated... by government. Banks have rules on what they can use the money in your savings account for. They have government backed insurance. Regular stocks are also

Yes. By the end of the war, the USA had more carriers than then entire IJN surface fleet. Never mind all the cruisers, destroyers and such. And the fuel to run them. The Japanese had absolutely no chance to win the war.

For a 10 to 15kg gas-powered model aircraft, a simple 4m launch rail is sufficient. For launch assist, that could be a spring or catapult system, or a small solid rocket motor. Can easily be mounted on a truck or small boat. Something like

With standard electric motor quads, the range is very definitely an issue. But you could create a long-range gas powered plane, with Ardupilot and a GPS receiver, and get pretty long range with that. Here is one that crossed the Atlantic o

Yes, it is bleak. We'll be talking about nuking a volcano at some point, just to cut down the sunlight falling on the Earth.

Ooooo... that's right. I was reading about a related issue with (IIRC) Rust v1.51 on some 32-bit platform where they were running out of memory. Never mind how long that would take.

While everything you said is correct, we should all be aware that the existence of floating ice tends to hold back the glaciers that are on land. Without the floating ice, those glaciers will flow more rapidly off into the ocean, and that

If LLVM is now not a blocker, I wonder if they'll be able to start using Rust for development. At least as an experiment.

Is there a full and complete example of how to properly handle signals in a multi-threaded program that does the usual stuff (talk to disk, talk on the network)? Written in plain C? I think I know everything that I'm supposed to do

The other issue is that each nuclear reactor site is effectively unique. So there's whole piles of paperwork that need to be checked and re-checked to ensure that all procedures and everything is correct and up-to-date. With small mod

In some sense, the Shuttle program was in continuous development. But to give you some idea of the work involved in even the later launches, consider this: Instead of inspecting 24,000 tiles by hand , they developed a scanner to automate t

Per-flight costs for the shuttle was $1.6 billion USD (2010 dollars). A good chunk of that was refurbishment for the shuttle and the SRBs. I didn't find specific numbers in a quick Internet search. https://www.space.com&#x2F

It is a flawed comparison in the other way as well. The shuttles required vast amounts of refurbishment after each flight. While the thermal protection system was improved with the later shuttles, they required a lot of inspection and re

A sailboat is the original "carbon free" way of propulsion for boats and ships. No, it is not as fast as a hydrofoil, but it also won't run out of power except under rare weather conditions (utterly becalmed). Not that boats

I've been using a 46in 4K TV as a monitor, and the lag from the video processing felt super odd, until I switched the HDMI input to "game mode".

I'm of the opinion that those should just be disabled these days. Aside from the occasional AMD motherboard that has a very slow scrolling non-text-mode framebuffer, Ctrl-Q and Ctrl-S aren't so useful with the GUI terminal program
