vilhelm_s··on AP fired reporter after dangerous blunder – Slack chats reveal chaotic process
You can see the alert here[0], it does not have any byline. If you view the source of the page it has a "timestamp" like this:

<span class="Timestamp Component-root-0-2-39 Component-timestamp-0-2-38" data-key="timestamp" data-source="2022-11-15T18:41:15Z" title="2022-11-15 18:41:15 - Tue Nov 15 2022 13:41:15 GMT-0500 (Eastern Standard Time)">November 15, 2022</span>

which exactly corresponds to the 1:41pm "alert sent" message in the screenshotted Slack conversation. So they did indeed publish it based on this Slack thread.

vilhelm_s··on The leap second’s time is up: world votes to stop pausing clocks
I propose waiting a thousand years, so that the difference builds up to an hour, and then handle the adjustment as part of the daylight savings reform, which should just about have worked its way through the U.S. Congress and the EU institutions by then.

Facebook Research has indeed made a prototype for a sunglasses-sized VR headset! https://research.fb.com/wp-content/uploads/2020/06/Holograph...
vilhelm_s··on A rash of nearly lethal mushroom poisonings in Ohio
The article calls it a "plant identification app", I guess it's not specifically for mushrooms.
vilhelm_s··on Chernobyl black frogs reveal evolution in action
I think apes are generally black or brown under the fur, not pink. See e.g. https://www.reddit.com/r/pics/comments/bacdh/here_is_a_pic_o... https://twitter.com/gorillasdaily/status/1417126388281266185...
vilhelm_s··on The fight against drought in California has a new tool: The restrictor
You can still grow tomatoes outside California though, surely production would shift to a place with cheaper water? And if the prices are too high people would stop buying tomatoes.

I agree that the prices would not be exactly the same, my point is just that these prices are still extremely low. You don't need to fear people dying from dehydration (like the comment above suggested).

vilhelm_s··on The fight against drought in California has a new tool: The restrictor
The prices should not go up a lot, because if they did, farming would become unprofitable.

E.g., tomato farming produces around $4000 worth of produce per acre and year[0], and requires 2.5 feet applied water. ($4000/acre)/(2.5 feet) = 0.5 cents/gallon. If the water got that expensive they'd need to stop growing tomatoes, since just the water would already cost more than the produce would be worth.

By contrast, residential water is 0.7 cents per gallon[1], so the prices involved are really tiny compared to what human users are already paying.

vilhelm_s··on Mission to reach and operate at the focal region of the solar gravitational lens
Not really, it's the velocity the "Breakthrough Starshot" probes would reach. They propose[1] that launching each probe would take 84 GWh, which is not super much (about 15 times more than a space shuttle launch), but of course the Starshot probes would be much lighter than this proposed telescope so it's not directly comparable.

vilhelm_s··on Glassdoor ordered to unmask former toy company employees who posted criticism
Truth and honest opinion are both defenses under UK law. https://www.carruthers-law.co.uk/our-services/defamation/def...
vilhelm_s··on Glassdoor not so anonymous
I think maybe this is because the user who left the review is a New Zealand national residing outside the U.S., so they do not have any first amendment rights. If the user was American, I think they could assert a first-amendment right to anonymous speech to prevent being identified. (Although such a right is not absolute, there is a balancing test involved: https://storage.courtlistener.com/recap/gov.uscourts.cand.36...)
vilhelm_s··on MIT engineers fly first-ever plane with no moving parts (2018)
I'd absolutely expect the guy and his team to know about prior work, but the article comes from the university "news office". In my experience university PR releases are always extremely overhyped, particularly from the elite universities.
vilhelm_s··on EU reaches deal to make USB-C a common charger for most electronic devices
USB-C is infamous for being complex like that, but I think the charging part is basically fine? People talk about the Nintendo Switch often, but I have never heard any _other_ example of something where the charging didn't work, so I think maybe it's a rare exception.

(This is distinct from the "fast charging" mode(s?), which does seem to have compatibility problems. But in that case, the failure mode is that device charges slowly, which is probably not a big issue for the kind of small phones/gadgets that the EU regulation targets. The previous standard was micro-USB, which can't do fast-charging anyway.)

vilhelm_s··on An introduction to logical decision theory for everyone else
> LDT (logical decision theory) seems to be an umbrella decision theory that only requires the use of logical counterfactuals, leaving the iteration type and updatelessness unspecified. So my understanding is that UDT1, UDT1.1, UDT2, FDT, and TDT are all logical decision theories.

vilhelm_s··on One of the most popular activities in non-industrial societies: doing nothing
Is this because doing nothing is "popular", or because non-industrial societies don't produce enough calories to do more? There's an interesting blogpost[0] about extreme poverty in 20th-century Africa:

> He describes the narrow alleys of his neighborhood being packed with bayayes who just sit and stand around all day. Like, for the entire day. They have no jobs, no money, no goals, and they eat so little that they have no energy for leisure activities. The closest thing to an objective they have is keeping out of the sun, so they slowly move around the alleys to stay in the shade. Their highlight in a day might be some sort of public commotion, like a thief being caught, which will cause an enormous crowd to swell and watch the proceedings. [...]

> Kapuscinski constantly describes much of Africa’s baseline climate as so hot, humid/dry, bug-filled, and generally insufferable that even passive existence is too taxing to be productive. Ie. the people of Abdallah Wallo can’t work hard because it is literally dangerous to do so.

Doing nothing is the most common activity, but not exactly by choice.

vilhelm_s··on Ask HN: Why don't PCs have better entropy sources?
What kind of bugs are visible to userland? I would have thought a random number device would be the least likely thing to have upgrade problems like that: applications should not be able to assume anything at all since the output is literally random...
vilhelm_s··on YouTuber builds his own x-ray machine after $69k hospital bill (2021)
Steve Yegge tells the story[1] of his dad cooking:

> When I was a teenager, my dad and my brother Mike decided to make homemade chili. I'd never seen it made before, and I watched with keen interest as they added beef, beans, some veggies and spices, and other ingredients. Dad would taste it, add some more ingredients, wait a bit, taste it again. My dad has some pretty good recipes. So you can imagine my puzzlement when he opened the cupboard, pulled out 2 cans of Hormel chili, opened them and dumped them in. I waited a respectful moment or two before asking him why he was adding canned chili to his chili.

Similarly, I think it detracts a bit from building a home-made x-ray machine if one of the ingredients is an x-ray tube from an old x-ray machine.

vilhelm_s··on Wormhole confirms all $320M in funds have been restored
You don’t deposit any SOL to create wETH, you deposit ETH on the ethereum side. That’s what the name means, “wrapped ETH”
vilhelm_s··on Wormhole confirms all $320M in funds have been restored
creating wETH doesn't create any SOL, they are separate things.
vilhelm_s··on Wormhole confirms all $320M in funds have been restored
I don't think this is right at all. The attack first created 100,000 wETH ($320 million) on the Solana side, and then bridged 93,750 wETH ($250 million) to ETH on the Ethereum side [1]. So some of the added ETH backs the remaining 6250 "extra" wETH tokens on the Solana side, but almost all of it would have gone to replace the stolen 93,750 ETH, and that's a pure loss. Either way I don't think this would cause any inflation, since the wETH still corresponds 1:1 with locked ETH.

vilhelm_s··on French Navy ATL2 MPA: Someone Just Lasered The Wrong Aircraft
Cameras are very sensitive to lasers, there are lots of reported instances where a camera was damaged by e.g. a light show at a concert, even though it's presumably harmless to the human concert-goers[1]. So I don't think the fact that the camera was damaged would necessarily mean that it was dangerous to eyes.

vilhelm_s··on How do I open the Mercedes EQS’s hood?
Isn't that kindof what the list of warnings below the message provides? I think you can click on them to expand them, and based on what's in the owner's manual I expect one of the warnings is about "components under voltage".

vilhelm_s··on Regularized Newton Method with Global $O(1/k^2)$ Convergence
The story is told by Saunders Mac Lane, quoted in the book Mathematical Apocrypha Redux:

> J. von Neumann in 1927 introduced the axiomatic description of a Hilbert space, and used it in his work on quantum mechanics. There is a story of the time he came to Göttingen in 1929 to lecture on these ideas. The lecture started "A Hilbert space is a linear vector space over the complex numbers, complete in the convergence defined by an inner product (a product <a,b> of two vectors a, b) and separable". At the end of the lecture, David Hilbert (by custom sitting in the first row of the Mathematische Gesellschaft), who was then evidently thinking about his definition and not about the axiomatic description, is said to have asked, "Dr. von Neumann, ich möchte gern wissen, was ist dann eigentlich ein Hilbertscher Raum?" [Freely translated this is "Dr. von Neuman, I would very much like to know, what after all is a Hilbert space?"]

vilhelm_s··on IBM unveils 127-qubit quantum processor

vilhelm_s··on Penguin is no longer the owner of the copyright to The Tao of Pooh
In this case he granted rights to the book itself, not to make derivative works of it, so I don't think this clause is relevant. I think it's saying that e.g. if Penguin had made a tv-series based on the book, they would not lose the rights to the tv-series when the grant of the book terminated.
vilhelm_s··on Major nuclear fusion milestone reached as ‘ignition’ triggered in a lab
Natural gas plants are cheap but they cause global warming, so soon we will not be able to use them. For example, the U.S. target is to have zero carbon emissions from electricity generation by 2035, and zero carbon emissions at all by 2050.
vilhelm_s··on AI Recognises Race in Medical Images
In principle yes, but did you read the paper? They do a lot of completely crazy things like blurring the image until it's just fuzzy blobs, or doing a high-pass filter on it until it just looks like noise (they comment that a human could not even guess that it's an x-ray picture), and they still get very high accuracy. Basically no matter what they try they can still get the race out, with slightly lower percentage numbers. When reading it I also thought this is too good to be true, and they may have some kind of bug in their code...
vilhelm_s··on U.S. drone pilot leaks footage reveals accidental killing of children and adults
They are describing a particular incident when they were aiming at a man carrying a walky-talky, but the missile instead struck a different motorcycle with two adults and toddler. So killing those three people were accidental.
