No, he was posting a snarky troll - and being wrong while doing that is, well, kinda dumb.

Doesn't mean he shouldn't be called on it, while he's making stupid troll posts.

But they're not 4-10x more expensive than dental cleanings.

Have you checked? 'Cause if you haven't...

"The US" is not a monolith. Power outages are not a problem where I live. Last one I can remember was during Hurricane Isaias in 2020 - though to be fair, my power was out for 5 days that time.

Blert?

...for himself, sure.

Not "Crash Different"?

...for reminding me to put Linux on my old machines before October!

Three times - you forgot Great Britain.

...by using ice-9 instead.

...how to actually get usable power (i.e. electricity) from one of these things.

There were indeed movies set in/revolving around the strife in former Yugoslav countries. Sorry they weren't popular enough for you. Meanwhile, a hella lot more people died under the Nazis than in ex-Yugoslavia, so maybe you can be a little forgiving of people who think we should still talk about it occasionally.

...do they expect Hollywood to shoot for a 100% "global warming compliance rate" or something? I mean, are they expected to shoe-horn global warming into a friends-meeting-up-at-a-wedding comedy, or a teen-massive-party-after-graduation movie, etc.?

No, you do not know *exactly* where a satellite is. All measurements have error. You know where the satellite is, to some precision/accuracy. And the farther away *you* are from that position, the more that inexact precision contributes to error in *your* computed position. GPS is meant to be used for positions a few hundred to a few thousand miles away from the satellites, not 250,000 miles away. So the errors are large - 1.5 km according to TFA. Which is still great, all things considered, but not great for actual navigation on the lunar surface or in lunar orbit.
