I thought Edge had a "compatibility mode".

It does. I maintain some computers in a department at work where that feature is enabled for a state-government website our people need to access that still needs IE and Silverlight (!) to run. We keep a copy of the Silverlight installer on hand because you can't download it from Microsoft anymore, and there are some registry hacks involved in keeping this site running in "IE mode" (otherwise, the override to do so expires every 30 days). It's a royal pain in the ass, but expecting competence from the state is a fool's errand.

Are any of the people asking for this even Native American?

Magic 8-Ball says "very doubtful." These complaints are nearly always driven by AWFLs and other white shitlibs with too much time on their hands, and not the allegedly aggrieved.

no, the US Military isn't terribly interested in culture wars

O RLY? They seem to have jumped in up to their eyeballs in all sorts of toxic woke bullshit. Plug "woke military" into your search engine of choice for more examples than you can handle.

The AH-64 belongs to the Army, not the Air Force. ("Air Force," BTW, is two words.)

I'd rather buy a dumb TV too, but I settle for a smart TV where I never touch the smarts.

I was pretty much resigned to doing that when I spent a couple of days leveling up my parents' tech. The ancient non-HD flat-CRT TV in their bedroom got replaced with a 40" Vizio (largest that would fit the cabinet). For what it's worth, the TV wouldn't even connect to their network (couldn't get a DHCP lease), so it's effectively a dumb TV. A Roku stick was also purchased with the TV; it had no trouble tethering off their new cellphones until the cable company could come out to set up their stuff so Mom & Dad could shitcan all of the AT&T VDSL gear for which the service had crapped out two days before Christmas. The Roku is now on the cable-powered WLAN, pulling in TV through the service provider's Roku app (look Mom, no cable box!). Other than some cabling issues between the demarc and the street that were resolved with a second truck roll, the new setup is running like a champ.

BTW, AT&T needs to die in a fire. Their customer service is stuck 40 years in the past: "We don't care. We don't have to. We're the phone company." A 5-day outage with no idea when service might be restored is inexcusable.

To do that, they'd have to port it from Java to something that works properly.

In the meantime, you could switch to PlatformIO on VSCodium. It's worked for all of my embedded coding needs across multiple platforms, including Arduino.

expensive sewing machines seem to lag what a reasonable person would expect by a decade or more

Could it just be that floppy disks are still big in Japan? My mom has a sewing machine (think it's by Brother) that does embroidery. I think it runs Windows CE or something similar (it has a small LCD touchscreen through which it's controlled), and I'm pretty sure it has a floppy drive for moving data in and out...don't recall if it also has a USB interface or not.

It never really stopped being a thing in the UK

One Christmas morning (can't remember if it was '84 or '85), it got cold enough overnight that there was a light dusting of snow outside...and the milk bottles started freezing before we brought them in. We were buying non-homogenized milk, where the cream floats on top until you shake it back in. The cream was freezing a little bit faster than the rest of the milk underneath, and the bottles were close enough to full that the foil caps were getting blown off. Good times. :)

Diagramming sentences is a distinctively US thing

I also suspect it's dropped out of use in more recent (and not-so-recent) years. It may have still been a thing when my boomer parents were in school, but I never encountered it in school in the '80s and have only the vaguest idea what it might be. I still managed to swing a 630 SAT verbal when I was a junior, and before that, the 430 I'd gotten when I took the SAT in 7th grade was said to be above the average score for college-bound high-schoolers. That would suggest that an alternate method to teach the same material is in more common use today.

Glass milk bottles have been out of the public consciousness for long enough

Milk delivery in the US has never been a thing in my 50 years, but when my family moved to England in the mid-'80s, they were still delivering pint bottles in the wee hours. We usually bought two pints daily, unless there was a reason to order more or less...you set a dial on the basket that you put out with the empties that said how many you wanted. Given the slow rate of change over in that part of the world, it wouldn't surprise me if milk delivery is still a thing even today.

But ballistic missiles work for that.

Ballistic missiles can't be recalled once they're launched, if it's determined that there's no longer a threat. Maybe you can tell it to self-destruct, but even doing that over enemy territory is likely to have consequences. With a bomber, you tell the crew to RTB, they do a 180, and sometime later, they're back on the ground.

Knock off the gaslighting already, Mr. Fauci. Nobody with two brain cells to rub together believes you anymore.

BUT! Even outisde of the US:
Nearly always, this only go up to 2 SIMs on the tray. (Personal experience: none of my phone ever had more).

What's the likelihood you'll need more than 2 at a time? You have your home country SIM in one slot and the country-you're-in-now SIM in the other. Unless you're someplace like Europe where you can cross multiple countries in a day's drive, this isn't likely to be a big limitation.

(FWIW, T-Mobile (in the US, at least) provides free international roaming in most of the world. I've kept their SIM in while in Mexico and the Bahamas without issue. The only country I've been to that wasn't covered was Fiji, for which I bought a SIM at the airport with a week's worth of service, put that in my phone, and stashed the stateside SIM in a safe place until I left since my phone at the time was of the more common single-SIM variety. I think a dual-SIM tray is available for my current phone (a OnePlus 7 Pro), but I'm not sure if it'll work in a phone that shipped with a single-SIM tray.)

I hope you travel with a lot of surface spray and disinfectant wipes if that's really a concern for you.

I do, like every germophobic hypochondriac.

FTFY.

When I visited Copenhagen last, it really didn't matter what was on the ground.

That probably holds up anywhere cold you might go. My first year of college was at the University of Illinois, and people kept biking through the winter there. I only wiped out on ice once, after which I was more careful taking turns when snow was on the ground...just like you'd be more careful driving in similar conditions. Funny how that works. :)
