The video doesn’t really prove anything. Non-superconducting diamagnetic can’t freely levitate due to a fundamental instability; they will always fall out of levitation (unless they’re spinning in a specific way). The superconductor in the video is in physical contact with the magnet beneath it, which is enough to resolve that unstable condition and keep the material steady.
Not sure if this is currently possible but I would love if you were able to extract the dates from multiple docs at once. So I could for example have separate docs for different meetings and then put the relevant dates in each specific doc but then have a single view of all dates.

Edit: it turns out you've done this at least once before (https://news.ycombinator.com/item?id=36552205). Obviously the war makes for strong and legitimate feelings. But commenters here can be, and need to be, peaceful enough not to blame or put down entire countries/histories/cultures. Otherwise we're just propagating more war, which is certainly not what HN is for. That follows from the principle of curiosity which we're trying to optimize for (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...).

Also, you've been breaking the site guidelines quite a bit in other places that have nothing to do with the war:

What the simulation is saying though is that it requires some luck, not all the arrangements result in the band structure.
What does this have to do with what I said?

Transaction volume doesn't mean a fiddly-fuck, unless you're measuring network effects, and even then, context can become pretty important.

No, if one thing should be clear to someone reading this thread, it should be that there's only one thing that matters: liquidity.
I did physical labor on a commercial farm for eight years, and I only left because of a change in management that I disagreed with. After that, I got an office job, and it's honestly a lot harder on my body; I am way more sore and achey all the time now. The job before it was retail (standing all day), and that was better than office work, but still nowhere as good as getting real exercise all day long.

So there are ways to do physical labor that do not harm you, but a lot of these come down to management and are not up to the individual employee. You could definitely hurt yourself very badly if you do it wrong (which you won't generally do naturally -- our bodies give us lots of warnings -- but pressure from above can make you ignore those warnings and drastically shorten your working life).

Fortunately, the company where I did labor really tried to be a healthy place to work, and that made such a huge difference. A lot of my coworkers had been there for 30 years or more, and they were still zipping around like they were 20.

These are some things that really help:

- The work needs to not be too repetitive (you need to switch tasks several times a day, and each task needs to use different parts of your body).

- You need breaks. And not just at set times of day, but also just whenever you need it. If you do something to yourself that feels funny or not quite right (a warning sign that you are on the verge of a sprain or some other injury), you need to be able to stop working immediately until the feeling passes.

- You need to do work that is within your capability. It's OK to work extremely hard, to go home exhausted, and to feel muscle soreness the next day. But if you do something you're not strong enough or quick enough to handle with total control, you are likely to make mistakes that lead to injuries (tripping, dropping something, using poor form, etc.). Such injuries can be severe and lifelong, so you should absolutely never work at the edge of your ability.

- You need to be well-slept and well-hydrated (cold water and electrolytes should be available at all times, with absolutely no delay), and you must have appropriate clothing and a way to temporarily escape from the heat if you suddenly feel faint. You can work extremely hard under surprisingly harsh conditions (I did hard labor in humid, 100-110 F greenhouses day after day and felt great), so long as your body's basic needs are met.
There's also been xperf and Process Monitor for a long time. It's not clear to me from the article why they needed to use the underlying API instead of the tooling built on top.
Also helps if you mention you’re a researcher at OpenAI working on AI alignment. It thinks AI alignment is super important.
You mean like a new element? We haven't even managed to synthesize all the ones we believe can exist, because they get very unstable.

Or maybe a way to make up different non-atom things out of subatomic particles and keep them stable?

So long as the new thing has some signature on some of our sensor technology we should probably be able to deduce what it is (this is sort of what particle physics folks have been doing for some time).

If we were presented with somethign truly novel like this it would be a "drop-everything, go all in on the science" while also sort of reflecting on how little we really know.

> So the groups trying to replicate right now are basically wasting their time?

If a few dozen groups all try and replicate, and there is something to replicate, then odds are good someone will get lucky (birthday paradox and all that). Each individual group is definitely wasting their time, but the aggregate time spent may not be a waste.

The parameter space for such a search even with a limited number candidate materials is immense. You'd need to guide the search somehow, that band structure might be the one, or it may not be... and every candidate that you flag will have to be synthesized which may not be all that easy.

They do that every now and then. Peer review rarely, if ever, involves any sort of replication.
I'm just saying that it's not really LK-99, then. It's something else that needs to be specified more precisely.
I get a strong feeling that this guy is like the lab that said they found life that didn’t use phosphorous for dna a few years back. I think it just turned out to be shoddy lab work and not accounting for contaminants in their lab chemicals.

I'm sure you are right. But watching someone disengage from a physiological dependency is a different class of experaince. Like watching someone get their arm ripped off.

This guy talks from experience from his experience with meth as a multi-addict: https://www.youtube.com/watch?v=f0HtlAlmdxk Very compelling.

In this vid: https://youtu.be/KoVOSmSbPMQ?t=553 he states that of all the addictions he has had, meth is the one he can never completely loose. If he was alone in a room with it, he states that he would not last 20 minutes before succumbing.
Yes I had that thought, but your license looked custom so was not sure if that was allowed.
Sure but with such international intrigue maybe they can invite someone over to the lab for lunch and a quick test?
I understand. I'm saying that it's not LK-99 as described, then. Rather, it's something else that needs a more precise specification.
"Reading their resume" means not giving me more info beyond what's literally in their resume.

Example:
"Oh well I've worked with React before. It was an interesting project. It was for an ecommerce project. (endless silence after)"

"Start saying nonsense" means they're just making things up.

Example:
"So yeah I've used git before. It's a cool programming language. It reminds me of C. I love programming."
oh really ? Thats awfully kind. I'll take that in for EdgeChains as well.

You have to put in the structure and then it's expensive to do the calculation. The space of possible structures is extremely large. If you have candidates then you can run through them, but you can't just random search through trillions of trillions of candidates.
I never bought into the Jamstack.

Static website --> Use one of many no-code/low-code services. There's no longer a big market for static websites built from the ground up.

Database driven pages --> Impractical with Jamstack. Client-side rendering is ok. SSR is usually best.

Website that has static pages and database driven pages --> Same as above. This is why I always told people to start off with Next.js, even if you're making a static website. If you ever want database driven pages, it's far easier to add them if you're already using Next.js but not if you're using something like Gatsby.

I've never bothered to learn any Jamstack frameworks because of the above reasoning.
Great to see. jq is nearly as ubiquitous as bash these days.

I’m excited about pick()! Could have used this so many times:

> Adds new builtin pick(stream) to emit a projection of the input object or array. @pkoppstein #2656

$ jq -n '{"a": 1, "b": {"c": 2, "d": 3}, "e": 4} | pick(.a, .b.c, .x)'
{
"a": 1,
"b": {
"c": 2
},
"x": null
}
Most science is way too boring and requires way to much work to reproduce to follow this kind of model. This open science type work we are seeing for LK-99 works fantastically when a huge number of scientists are interested in the problem and motivated to study it. Most papers aren't even cited more than a dozen times if that.
If you're trying to minimize human caused warming with the rare eruption of super volcanoes, it's pretty weak.
DFT scales horribly so it's phenomenally expensive to run. You have to have some other mechanism for knowing the general atomic layout before entering the DFT realm.

Once you know the atomic positions you can then do little perturbation simulations to model phonon dispersions or ask electron density questions.

Edit: you've been breaking the site guidelines a lot lately. That's not ok. I appreciate that you have deep reasons to feel strongly about the war, but you've been breaking HN's guidelines in plenty of other contexts too. If you keep this up, we're going to have to ban you.

Defining LK-99 as “the thing you get from following the steps in this paper” and not “the allegedly superconducting material these guys have a sample of” is silly.
I don’t think we’d necessarily have to use it for transistors, but could use it in place of the metal interconnect that is significant in terms of resistive loss.
I had to build and edit spreadsheets with the OpenXML SDK.

I have absolutely zero clue what the hell microsoft was thinking with this. Most of the use cases don’t give two rats shits about the different “parts”, but the api forces you to manually create them anyway. Why? Presumably so you know the parts exist?

Never mind that some, but not all (of course) formatting parts of the api require undocumented magic values in magic slots.

I don’t know if it’s as bad as this event tracing, but I do know that OpenXML is by far the worst api I’ve ever personally been abused by.
My understanding is that it is due to the lower voltage drop across the base junction. Germanium is .3v vs Silicon .7v, so with germanium you get less "crossover distortion" when the input signal is crossing the 0 line.

edit: I understand that typically this is biased out with diodes...but the matching is not perfect and it is easier to start with half the distortion.
Ah, so LoRA / RLHF?
They did tests, and they also said, explicitely: "The human health effects of plastic exposure are unclear"

Everything else is in vitro and non-obviously harmful endpoints. There is not a single iota of direct negative health impacts in real people.

One of my all time favourite short sci-fi stories is "The Coffin Cure":

It's about a guy who cures the common-cold ... and the consequences. Always had a soft spot for it.
I'm not following you. The compound is specified, the process is what is poorly specified and the researchers more or less admit that they do not exactly know what the right method is. This makes it a lot harder to replicate and may well cause a lot of attempts to misfire before someone finds something that works or we give up on the search. What TFA here suggests is that there are some potential complications in manufacturing this that would explain why the original researchers had problems trying to make the compound, the number that I recall is that '1 in 10' tries resulted in a working sample.

That would also be a fantastic way to pull a hoax, because it will result in 10x more effort spent on your hoax. If it turns out that it was a hoax I think the original researchers will find immense gratitude from Pons and Fleischmann for taking over the top spot for the textbook example of bad science. But for now, as far as I can see the jury is still out, and if anything the paper linked here actually improves the chances of it being real a bit more than it is offset in the other direction by a failed replication attempt.

>the impacts of these plastics in real life is completely unknown

There's a huge body of research on endocrine disrupting chemicals, specifically from plastics, going back decades. The science is settled here.

https://www.sciencedirect.com/science/article/pii/S030372072...

The article links sources, but it's trivially googlable.

There's tons of evidence that these chemicals cause problems with sexual development and fertility, there's also lots of evidence that plastic containers leach them when microwaved. As the article states, it is obvious what people need to do. Glass containers are not expensive, and disposable food containers NOT made of plastic were commonplace up through the 90's and they can be again. Switching to glass and aluminum containers when possible is actually better for the environment as well, since they are actually recyclable whereas plastic is guaranteed to end up in a landfill eventually.

>Avoiding plastics can be extremely expensive

Tinfoil instead of plastic wrap, a glass Tupperware set is a few dollars more expensive instead of plastic, aluminum water bottles instead of plastic (actually cheaper than plastic bottles).

My family eliminated plastics from our lives and it cost us basically nothing. In what way is it extremely expensive?
I think Josephson junctions. Also maybe you could eliminate copper loss by using LK-99 interconnect layers.
So, do you think that people who buy weed while under the age of 21 should face legal repercussions? And likewise for people who sell weed without checking for ID?

Similarly, I will never understand Central Park in New York City. I was there a couple years ago and the vast majority of the grass is not meant to be walked on. Most of the paths have a little mini fences surrounding them and there’s tons of signage saying not to walk on the grass. There’s exceptions here and there throughout park park, but generally it’s a park where you’re not allowed on the green spaces, which is just absurd to me. I’ll take the openness of Golden Gate Park in San Francisco over the travesty that is NYC Central Park any day. But of course Salesforce “Park” in San Francisco is similar, you’re not allowed off the paths other than certain small approved lawn areas, and the security has yelled at me about it multiple times. So much for a public park.

What does it mean to scan for vulnerabilities using AI? My experience is that static analyses are hard to make productive (in terms of false/true positive ratio) in even the best scenarios (static languages, small codebases, limited interprocedural control- and data-flow); it's not immediately clear to me how a ML model running on something as dynamic as JavaScript is going to perform on novel inputs.

(Please don't take this as a personal criticism; congratulations on your internship project!)
I know this isn’t about the signing really, but it is my understanding that you sign things with your private key and people can verify that it was you who signed it with the matching public key.

HN or HN mods are against British people? Have you never seen a single one of the Monty Python links I've posted?

This is an example of how everyone with strong passions always feels like the community and/or mods are against them*. It's striking to what lengths this principle can go. (Not to pick on you personally—this mechanism seems to be hard-wired in all of us.)

I promise you that neither the mods nor the community hate British people. Personally I love them/you, and I'm confident most of the community here ranges is neutral or better, and nowhere near hate. No doubt some nasty comments have appeared here, but that's because everything appears here. It's a large public internet forum.

https://en.wikipedia.org/wiki/Missing_stair

>The missing stair is a metaphor for a person within a social group who many people know is untrustworthy or otherwise has to be "managed," but around whom the group chooses to work by discreetly warning newcomers of their behavior, rather than address them and their behavior openly. The "missing stair" in the metaphor refers to a dangerous structural fault, such as a missing step in a staircase; a fault that people may become used to and quietly accepting of, is not openly signposted or fixed, and that newcomers to a social group are warned about discreetly. [...]

>Meaning: The analogy of the missing stair makes it clear that the problem is the predator (the missing stair) and that the solution is stopping the predatory behavior (fixing the stair).

>An article about industry sexual harassment on comics news site ComicsAlliance posed the question: "Which one of these statements makes more sense to say: 'These people need to find more ways to stop people from harming them.' OR: 'These people should stop causing harm.' If you ever find yourself saying the former instead of the latter, take a moment and ask yourself why."[3]

>In a 2014 post on the anti-rape blog Yes Means Yes,[4] lawyer Thomas MacAulay Millar wrote that the missing stair analogy was consistent with his understanding of rapists' motivations and behaviors, based on research carried out by clinical psychologists David Lisak and Paul M. Miller, and by Stephanie K. McWhorter, a researcher with the U.S. Naval Health Research Center. Millar wrote that while a small number of rapists are "one-timers" who may be making a mistake or are confused about consent, the majority are repeat offenders, averaging six rapes each.[5] "We need to spot the rapists," Millar wrote, "and we need to shut down the social structures that give them a license to operate. They don't accidentally end up in a room with a woman too drunk or high to consent or resist; they plan on getting there and that's where they end up."[6]
