The main issue is that the length of a day is not actually constant. Leap second occur (in either direction) which mean that a day is sometimes one second shorter or longer. Timezones and DST also can make a day a whole hour longer or shorter.

Seconds are a unit for physical measurement. They're always the same length. Minutes, days, weeks, months, years, etc are imprecise shortcuts that are convenient for our society but this convenience sometimes comes at the price of being bonkers units from the physics standpoint.

As much as I'm careful about Google keeping my data, I have to recognize that this has helped a friend tremendously. He was separated from his ex, she had left with their daughter, and he was trying to get split custody. She testified he was a deadbeat dad, and she put it in writing that he had never been to pick up their daughter at school, never taken her to her regular weekend club activities, etc.

He reached out to me asking if his location history could help prove she was full of shit. It took me an hour or so to figure out the right way to process the data, but then I was able to give him a detailed list of dates and times he had been to his daughter's school, poney club, etc. His lawyer attached that to their rebuttal. I like to think it made a significant difference. He did get joint custody in the end.

You don't need a B license but you need a motorcycling/small engine vehicle license (BSR) like for a scooter, at least. I do wish the bar was a little higher though.

How should people refer to you in the third person? It's okay to use one's name as the preferred pronoun.

Paragliding is an unforgiving sport: you're gliding, hoping to find updrafts to give you some more altitude so you can reach high enough to cross to another spot that hopefully also has an updraft, etc.

At a guess, this guy was hoping that he'd find a last-resort updraft in this area. OP, do you live maybe in a small-ish built area surrounded by fields or forest? Those tend to get hotter than their surroundings and are great for updrafts. But generally you don't want to land in residential areas, there full of obstacles which make for unpleasant landing conditions.

Maybe https://tailscale.com/blog/ssh-console/ could help - they run a tailscale client in webassembly in the browser, plus a ssh client also in webasm, so you can get ssh to the tailnet without installing anything.

Because this works over DERP it probably even works on very locked down computers behind very strict firewalls, e.g. that only allow TCP 80/443 :)

Oxygen is found in 3 forms: nascent (O), molecular (O2, the most common) and ozone (O3). Nascent oxygen, due to its electronic configuration (i.e how many electrons it has and how they're spread out across its electronic shells) is unstable, and tends to quickly form bonds with another O, forming O2. This is also the case e.g. for hydrogen, which is usually found as H2.

You can find O in this form in some environments, in the upper atmosphere there is enough UV radiation to break up O2 into O.
