The GPS ‘time zone’ does not account for leap seconds at all and is currently 18 seconds ahead of UTC. The GPS navigation messages from the satellites do however include the current offset.

Yes. 1/2 c is super fast still and gravity that strong would have effects like noticably bending outgoing light.
Neutron stars are right on the verge of becoming black holes and are incredible.

Good to know, thanks!

Could it just be any post that is ‘friends only’ or if the user has blocked anyone?
Sounds like it’s not systemic like Twitter or Reddit requiring logins for virtually anything.
- Comment on HRT Harm Reduction Toolkit Game Bundle - $25 for 30 games 1 week ago:
For some reason they don’t mention in the description that most or all of these games are not videogames, they are tabletop role playing game manuals. (The digital downloads are .pdf files)
Nothing wrong with that of course, but it certainly seems like an important detail.

Changes in the gravitational field definitely travel, and do so at the speed of light.
Look up LIGO
- Comment on Gottem. :) 2 weeks ago:
Expanding a little on the last part, Earth’s orbital velocity is about 29.8 km/s so that’s the speed at which we would suddenly be leaving the former location of the solar system in a direction that depends on what time of year it happened. Regardless of direction though, the escape velocity of the Milky Way around where we are is about 544 km/s so there’s no way we’d be leaving the galaxy. On the other hand the plane of the galaxy is only about 6 degrees off from the galactic center at the moment, so if this happened at the right time of year (don’t know when that is) we could launch somewhat towards the core. We would not however get very close to it because the sun’s own orbital velocity is about 230 km/s so we’d still be in close to the same galactic orbit overall, just potentially a bit more eccentric.

The electrocution risk would actually last even after it’s unplugged: Power supplies can have big capacitors in them.
- Comment on What are your favorite board games? I'm looking for games that are satisfying and lead to a sense of accomplishment or fulfillment or connection. 3 weeks ago:
Just One can also do a lot more than 4 players. If you add additional writing surfaces and erasable markers (or pencils or whatever) it’s pretty much unlimited.

It’s .ml that can’t stand a little bad language. I doubt they are scanning images though.

- Comment on Anon comes up with filenames 1 month ago:
Yeah, I agree, usually it does
- Comment on Anon comes up with filenames 1 month ago:
No idea, best I got is that maybe the default name is always the same from whatever source they are using, so they would get the pick a new name dialog anyway.
- Comment on Anon comes up with filenames 1 month ago:
Yup, very much so.
- Comment on Anon comes up with filenames 1 month ago:
My guess is they are images and the thumbnail is more important as an identifier than the name would be.
- Comment on Anon comes up with filenames 1 month ago:
There’s also the birthday paradox to consider - each new file increases the number of potential matches for all files that follow, and also is a potential match for all files that precede it. The total number of ways to match is something close to the square of the number of files.

I mean the actual text that was LLM generated was deleted. The header had been left mentioning it as a joke. Note the discussion section.
- Comment on Skew-T Log-P (xkcd) 1 month ago:
The LLM answer was deleted even before I posted the link. As mentioned the header is always a joke, and in this case it’s referencing that, but over the next few days I expect that link to become useful.

Genshin Impact just released a new version that for most of the world became playable on Jan 1, but where I live it started several hours before the end of Dec 31.
So that.

For April Fools, Cards Against Humanity was literally selling diamond studded potatoes for $69.99 (USD) - and claimed a $1000 value, which I’m sure they would be at retail prices.
The FAQ said they had thousands of them, but I didn’t get there in time.
- Comment on Anon's sad story 1 month ago:
I have a similar story of woe.
Before they got rid of them, I bought a churro and was walking to the parking lot when I tilted that stupid sleeve (it’s not a bag) the wrong way and the churro slipped out and landed on that nasty pavement. A few months later my mom died.

Racy!
But seriously, seeing the older people made me realize that those guys wouldn’t have even had cars all over when they were growing up.
From Wikipedia:
“The modern car—a practical, marketable automobile for everyday use—was invented in 1886, when the German inventor Carl Benz patented his Benz Patent-Motorwagen. Commercial cars became widely available during the 20th century. The 1901 Oldsmobile Curved Dash and the 1908 Ford Model T, both American cars, are widely considered the first mass-produced and mass-affordable cars, respectively.”
(First gasoline car at all was 1808 though)
So this was at most around 21 years after the Model T. For anyone much older than that, cars would have been rare at best when they were young.

From what I read, the policy of removing domains when the county stops existing was directly based on what happened with .su so that never happens again.
