The last guy on Putin’s naughty list to fly into Moscow got an AA missile up the tail. Put me down for that.

physicists are quite confident only blackholes can Hawking radiate

Good to know! I was starting to get worried :D

you absolutely need a horizon to get radiation

Does the particle need to travel all the way from the horizon to reach you? How long does that take? The horizon still exists on the centrifuge, if only for a moment, shifting slightly from one instant to the next. In principle, at any moment you could detach from the centrifuge and fire 10g rocket thrusters in a straight line instead. In that first instant there is no way to tell the difference between the two.

I say this because in the linked paper, the “acceleration” experienced by the positrons was the bouncing off the atomic nuclei in the silicon crystal, which takes place over the space of a few angstroms, or at most within the 3.5mm size of the crystal, in the time given by the speed of 178GeV positrons (+Lorenz contraction). This instant was sufficient to claim Unruh effects were occurring.

Another complication is that even if the centrifuge slows down as it gets heavier, you can recover most of that mechanical energy when you hop off the centrifuge with your now full jar. Then you can boost it back up almost up to full speed. So I’m not sure exactly at what point you input energy into the system to instantiate the particles. When they hit the belljar bottom transversely maybe? Is this some kind of Maxwell’s Demon situation where you need to close the jar before the particles fall back out?

Also good to mention Earth! Logically, if Hawking radiation works for black holes it seems as if it would also work for any star or planet! But I’ve never seen this mentioned anywhere.

You know, I was beginning to second guess myself. Maybe the nimbys know something I don’t? After all, nimby rights matter too! I don’t live in Astoria or run a business, I only travel and shop there. Maybe their safety concerns have merit?

We had our group ride of support, and I have now personally seen the two-block section where the repainting work was already completed, before the court injunction took effect, (and where car parkers actually obey the new parking markings), and it is marvelous. The bike lane is comfortable and with great visibility of street and sidewalk, much better than the slalom course it was before. There are two parking spaces between each pair of columns that can fit two cars with ample room or an extra long delivery truck. With a couple extra physical improvements, like flying island bus stops and extra-wide sidewalk cutouts at intersections with ramps for curb-level bike path crossings, Astoria 31st Street redesign could become a reference model for all the other elevated track streets in the city. Having seen it, the design just makes sense and impossible to imagine going back the way it was.

As a person who spends inordinate amount of time thinking about street lane width allocation and reading DOT engineering proposals, I can now confidently say that the nimbys were complete shitheads all along, as they always are, all the time, and I should have never doubted myself. And if you had any doubts too - don’t.

The crazy thing to me is that as you look at galaxies further away, they become bigger in the sky. Obligatory xkcd: https://www.explainxkcd.com/wiki/index.php/2622:_Angular_Diameter_Turnaround There could be huge dragons out there occluding half the sky, but they’d be beyond the last scattering surface of the cosmic microwave background.

Ahh! Malicious compliance. Beautiful.

Agreed! That’s why I much prefer the “Is there any possible way you could be pregnant right now?” phrasing. Which is straight to the point of “we are about to operate on your abdominal section that could cause fetal loss if we are not aware of it, assuming you care about that sort of thing.” But if you are getting the period question, then it’s just a nurse checking off a box on an insurance checklist when you are there for an ear infection, and 100% of the time it is not relevant then.

Woops, sorry! I got immediately multiply downvoted 100%, I haven’t posted in this community before so not familiar with the culture, and even though I thought my response was relevant, it didn’t look like the community was interested in such an opinion, so I withdrew my post. I said something like that unless I am literally there do get tested for a suspected pregnancy, I would tell them it’s none of their business, or more politely, “given the current political climate, I do not answer questions like these”. Thanks for checking up on me!

End of Eternity (1955) by Isaac Asimov (and its reimagining in Palimpsest (2009) by Charles Stross) involve a time-traveling secret organization that has its headquarters hidden away in time/outside of time. They don’t so much drain resources though as manipulate history to ensure a safe course.

1 life-year saved per 900 vaccine doses administered

To flip the ratio, you getting the vaccine extends your life by 1/3 of a day. This might even be a wash if you had to take a day off work or wait on line for several hours. More effective if you’re elderly, but then also you got fewer life-years to save. Hmm.

The numbers in the meme are off. One sperm is 750MB, or about 1 CD, so full human is 2 CDs. Or a couple 1.4MB floppies if you only store the diff from the reference genome.

I ended up doing a recheck. On the plus side, the verification found several instances of bitrot from the old failing SSD. Fortunately, all the 99%-complete torrents quickly re-downloaded themselves. The whole internet is my backup!

Robin Hanson is in the house!

There is a crazy idea that since Peano arithmetic has not been proven to be consistent (and cannot be proven so, by Goedel’s Theorem), if you ever find a counterexample you can use nondisjunctions like these to immediately effectively prove anything. This may have dubious effects on objective reality. “I have one apple and one apple. Since I can prove that 1+1=5, I now have 5 apples.” And boom! You got 5 apples.

It’s unthinkable that CMS would violate the trust of Medicaid enrollees in this way

Once again stolen medical records are being used for state oppression. In WWII, the Netherlands suffered 75% of their Jewish population killed - the highest of any country even Germany - because the invading Nazis made a beeline for the medical records archive where the government kept a meticulous track of all Dutch citizens. I never volunteer race or ethnicity on any such forms - there is no medical benefit, it can only come back to hurt you.

/s I hope?

• eating meat -> vegetarianism/carnivorism -> environmentalism/global climate change/ethical treatment of animals/ethical treatment of humans -> politics
• additives/plastics in food -> government regulation of ingredients/maximum allowed pollution levels/rules limiting plastic packaging -> small/big government/regulation vs. personal freedom -> politics
• ethnic food -> immigration/integration/multiculturalism/isolationism/white cultural genocide -> politics

I don’t know why there should be a divide on beliefs about climate change between Republican/Democrat political parties, but given that there certainly currently is, climate change and everything related is now political speech.

can be configured per application

wireguard can too using network namespaces

not exclusively as an interface in kernel mode

Which devices are you people running where you want VPN/proxy but don’t have kernel permissions to run wireguard? Firefox on iPhone? Porn on wifi washing machine?

Curious, what is SOCKS5 used for that regular wireguard cannot do? I’m only familiar with the use case of telling Firefox to connect through a SOCKS5 proxy, which may be convenient as a form of split tunneling - only firefox traffic goes through the VPN and everything else through clearnet - but wireguard can be configured into a split tunnel form as well with a bit more work, and works for all software not just the ones aware of SOCKS proxies. Is it for use on a system where your permissions are too limited to turn on wireguard but not so limited that you cannot change Firefox proxy settings?
