There are quite a few studies, but most are fairly low quality. Think questionnaires, polls, and surveys, instead of empirical research measuring how much time people spend on social media correlated directly with mental health outcomes, like depression diagnoses or or other disorders. There are *very* few longitudinal studies that look at social media use over time. Most combine multiple existing studies trying to correlate unrelated research into screen time, social media use, and mental health outcomes. None normalize for potential confounding factors, like increased reporting or self-diagnoses of issues.

The Amiga had a proper bus with a controller (the Angus.) It wasn't any faster than ISA, but the CPU could do things while the Angus dealt with DMA IO stuff. ISA could do DMA, but it was up to the expansion cards to do handle it, and *everything* had to place nice with each other. I remember a friend trying to get his shiny new AWE64 to work with his off-brand beige box. Either the printer port or the sound card could work, because they had incompatible DMA channel-address space combos.

Kind of amazing to think that memory, serial ports, hard disk controllers and video cards could all sit directly on the same bus and, more or less, get along. Anything more complicated than a PDP-11 at the time had, at least, a separate memory bus.

I'd imagine it works the same way VxWorks does, which is what most car companies use (along with, sometimes, QNX.)

This was before everyone was putting a tracking device in their pocket.

If the market for energy were floating, you'd be right. There are government mandates on cutting coal mining, reducing the number of coal plants, restricting licenses on existing coal plants, cutting co2 emissions of energy production, and mandating non-co2 producing energy generation.

Which is all fine, but there are economic repercussions if you are simultaneously dumping cash into that same market.

To be fair, in the olden days, the police would grab someone, say "You are guilty of xyz" take you in front of a judge, say "He's guilty of xyz" the judge would go "Yep!" and you'd be in prison.

Nowadays they have to come up with actual evidence, which is just exhausting. Phones have made it somewhat easier, as they can just subpoena the GPS info for anyone who was near a crime and you have an instant suspect. You don't even have to leave your desk, shoot off some emails and you get a suspect.

There's a reason that there is a saying that goes "Wears like leather." Leather is an excellent material to make durable stuff out of if it can't be made out of metal or needs some give.

If you want something more environmentally friendly than cows, horse hide is even more durable than cow leather and can be produced from horses that die naturally, but people think that having things made out of horses is icky for some reason. If you see a pair of officer's boots in a museum that are 200 years old and look like new, they are probably horse hide.

Know what makes something more affordable? Throwing enormous amounts of money at it. Works with student loans. Works with housing. Works with military hardware. Works with space shuttles. Make it clear that there is an unlimited supply of money in a sector and watch those prices come tumbling down.

Remember when the pentagon found $60 billion in the couch cushions to give to Ukraine last year? Good times...

From what I remember the original IBM PC only had a few dozen BIOS calls and some bootstrap stuff. Not sure why they thought that would be an insurmountable hardship for competing manufacturers to overcome.

I'd imagine they didn't want CP/M more splintered than it already was. The same thing ended up happening to MS-DOS. There was a version for Zenith computers incompatible with the version for the IBM-PC. Same with the Tandy portables and initial desktop PCs, and ITT, Olivetti, TI, HP palmtops, etc...

Yep, it will teach you to code using one or two languages and a couple of frameworks. You'll be great at those. Not so much anything else.

This was a plot point in Person of Interest. An AI was under attack by another AI, and downloaded itself into a large Pelican case filled with SSDs. At that point the show had kind of gone off the rails, but it was still a cool scene. Also, when they brought it back up (running on a janky supercomputer built out of consumer graphics cards) it was screwed up and didn't run well, which I appreciated, too. I miss that show.

Republican Andy Biggs, from Arizona, filed an amendment to the bill to prevent any use of wiretapping that involves American citizens without a proper warrant. Most Republicans voted for it, most Democrats voted against it, and it failed.
