>anonymous

Not anonymous.

>Russian

Not Russian, depending on who you're asking. Not Ukrainian, depending on who you're asking. There's a reason she describes herself as being ethnically Soviet.

>troll

Sure, she's a character alright. Doesn't mean she's wrong.

>proof is a photo of a spec of dust

Explicitly labelled as fanservice and not presented as proof of anything - she has explicitly requested that if people want proof, they should follow her procedures with appropriate safety and then once they get the same results as her they will have proof. She has also explicitly stated that her Twitter posts are not and are not intended to be a replacement for academic replication.

>She refuses to take a video

She insisted video was easily faked and the harassment + demands for proof would only increase if she did what her annoying reply guys wanted. She didn't make the decision I would like (I'd love to see the video), but it's probably the decision I would make in her shoes, going from a couple dozen followers to more than 20,000 in a week.

I initially thought she was over playing the "video is easily faked" thing, until a literal faked video (store bought pyrolitic graphite sputtering target on a magnet displaying its regular diamagnetism) went viral and got cited as replication of LK-99. That convinced me she was right, video can convey a false sense of authority. Better to report results and methods accurately.

>she says _she didnt follow the paper_ beause she immediately invented a better way to make a different room temp superconductor

If you are familiar with the academic history of what "replication of Western academic papers" looked like in the Soviet Union, you would understand where this academic methodology comes from. They were never given samples, could not reach out to authors for help, always had to understand the theory of what the authors were communicating at a base level and then try and implement it themselves. It is consistent with her professional background and culture that she would view it this way. If her method turns out to be correct, it probably deserves its own paper (appropriately citing the Korean paper, of course).

>she keeps tweeting bizzare USSR propaganda.

I think you maybe need to read more history or meet more Soviet-trained scientists if you think that this is a point against her as a scientist. Politically inconvenient, maybe, but the USSR had a very impressive academic tradition and made a lot of very good scientists. We have our own politically opinionated scientists here, too. Let the results speak for themselves.

I was considering a Model Y. My excitement has been waning though.

10 years ago, I thought that today I would be able to move 3 hours away and sleep in the car and commute to work because of self-driving. Clearly I had big dreams. But today, the range isn't any better than a gas car, they're not cheaper, sure they're quick cars, but most electric cars are. Charging them takes too long, can't be charged at a in a dense city. If you forget that you're close to 5% Battery, have a long trip in the morning, can't charge at your place in the city, but still have tons of stuff to do at home before the trip. Your only option would be to leave your car someplace charging for hours.

At least with a gas guzzler you can fill up 400 miles in a few minutes. The new hybrid concepts seem really interesting.
Because google lets you sideload. Even though almost no one actually does this, the option still exists in theory so you aren't forced to take googles offer.

DoorDash and Uber Eats are also economic disasters of incomprehensible proportions. They not only charge over double your total order, but many times they also have restaurants losing money on delivery orders too.

Just 5 years ago I used to be able to get lunch delivered by a Chinese food restaurant for under $10 in Brooklyn. Can't speak for today as I Escaped from New York, but good luck getting that very same order below $30 by DoorDash.
Show HN: McMaster-AR – View McMaster-Carr Parts in 3D and Augmented Reality
Excited to share McMaster-AR, a new Chrome extension that brings 3D models of McMaster-Carr parts to your screen, no downloads required.

The extensions adds a 3D viewer to the product descriptions of all McMaster-Carr parts that have CAD files. It also provides a link, via a QR code, to view the models in Augmented Reality on a mobile device.

For all the hardware folks on Hacker News, I hope this adds a new dimension to your McMaster-Carr shopping experience!

You can install the extension for free on the chrome webstore:

ADHD is a neurodevelopmental disorder. The symptoms of this disorder are caused by physical differences in the brain, right there in the prefrontal cortex where those responses to inputs are generated.

It sometimes happens that I just physically can't bring myself to complete some simple but important chore. That's not because I'm mentally weak, but because my ADHD brain does not provide the right amount of dopamine which everyone else with a more typical brain would get.

Conveniently, neither "fix the Economy" nor "fix the Climate" have tangible goals to achieve, making a poll like this about as meaningful as "what's your favorite color?"

Seriously, what's the goals? Make sure no one makes more or less money than anyone else? "everyone free from want?" really? everybody can agree on that? When does my want obligate you to serve me, and vice versa?

Similarly with climate, we need to lower CO2 below pre-human levels? which time period did you mean? How about just removing massive numbers of humans? There's suggestions all over the range from reasonable to insane but the issue is more complicated than the simple "kiss our totem" demanded by those pushing it.

Yes I acknowledged that in another reply, new national security mandates while finally allowing foreign payment on wechat&alipay. PRC fine with foreigners, including business community, but on their terms. Which is basically don't be a spy or conduct activities counter to PRC interest. Including foreign compliance workers in country to help enforce increasing US sanctions - no reason to make it easy. People who do that while in PRC frankly should be scared shitless. Ultimately, no different from early 10s western NGO crack down and CIA network purge. TLDR is foreign intelligence network got rebuilt over time, hence MSS responds.

Same with US/west increasingly prosecuting PRC espionage (sometimes bordering on witchhunt - see China Initiative). Counter intelligence activity is up on both sides due to geopolitical tensions. Western foreign policy push narrative to western media playing up minimal detainment/exit ban threat as part of general people to people decoupling efforts. Record number of established academic / talent from west are flooding back to PRC, student permits to Canada/US about halfed last year. On PRC side, more capital flight. It's happening on both sides.

What's a bigger problem, capital flight and PRC not getting some tourists or western FDI (also miniscule as % of PRC investments), or US losing talent to PRC and unable to brain drain PRC talent. That's up to propaganda from each side to decide. Less people to people interaction isn't the problem to PRC increasing securitization, it's the acceptable cost to reducing espionage which is also happening in the west. Article framing completely/intentionally misses that, while also focusing on group that matters least, western tourists, and not talking about basic macro factors like ticket prices in Q1, and VISA backlog.
It sounds like a dumb gimmick, but I don't see anything morally wrong with it as long as the interns are aware of the deal before they accept the offer to work there.

Also, is it actually public? Or just shared with everyone inside the firm? If it's public, anyone got a link to the leaderboard? And if it's not public, then it sounds less like a gimmick, and more like a transparent stack ranking incentive program.

I have to pitch in and also recommend Unsong[1] by Scott Alexander, of Slate Star Codex and Astral Codex Ten fame. If you always wished to read a Pratchett book, but with jokes about technology and where the protagonist is a DRM breaker, this is that book. Genuinely one of the best things I've ever read.

Maybe the movie audiences, particularly the blockbuster theater-going audiences, are skewing older and more conservative/old-fashioned now. So the sexuality there tends to be a lot more repressed (while at the same time needing to be optimized around those highly defined abs, in order to maximize profits).

I agree except for the anxiety part. Just because it wasn't the problem for you that doesn't mean it's not widespread. I avoid news nowadays because most of it is just a depressing reminder of everything that doesn't get any better over time.
If by Europe you mean Germany, or by rebuilt mean maintenance, then, yes.

The level of rail maintenance in America (barely any) is illegal in the rest of the western world. Tenders for maintenance specify certain speed and safety limits that basically require rebuilding every few decades.

Only on private rail could a hedge fund approach work, where the capital of the infrastructure is extracted by way of not maintaining it, but instead slowing trains down and increasing their length to compensate for bandwidth loss.
normally I would annotate the edit, but I thought that it was fast enough to skip that step. alas.
so I have an HTTP endpoint which gets maybe 10 hits per day, and does some lightweight computations and records small amount of data.

Right now, this is done on AWS, with lambda + S3, and costs under $0.02/month.

Can you point me to something more cost effective that that? Don't forget I also need backup for data, automatic failover in case of machine failure or crash, amd no maintenance (like OS upgrades) for 5+ years.
It's greyed out and hard to read.
>It creates a totally hidden function.

Are you talking about child_spec/1? `use GenServer` honestly provides some pretty good QoL enhancements over `@behaviour GenServer`. I don't know when or if there was a change to recommending `use GenServer`, but I was pleasantly surprised when I started using it. Especially because I'm not writing new GenServers all the time, having guard rails is nice to avoid being slowed down by remembering all the boilerplate: init/1, handle_x/y, child_spec/1

It's even nice enough to give additional information about why its crashing so you don't get confused why e.g. the handle_call function is working. I make this mistake almost every time I write a new GenServer:

def handle_call(:ping, state) do
{:reply, :pong, state}
end

Before, you would just get this meaningless gen_server stacktrace that basically just says "it crashed lol". Now you get the additional hint of "hey you didn't define handle_call/3" when it crashes.

Yes, I was simply parroting my impression of the current metal categorization zeitgeist. I appreciate your enthusiasm for detail in this matter and enjoyed the scholarly nature of your post. I totally agree with each of your points. FWIW, I bought the nuns EP on its release date based on the review in Thrasher magazine so I think that qualifies me as OGMF :-). Musically, I consider MF to be a mix of speed metal, heavy metal and hard bluesy groove rock (e.g. the Bell Witch intro riff and many others).

Okay, the press release here has dumbified the explanation to the point that several commenters are confused as to what it's trying to do, getting hung up on the H₄. The underlying chemistry is somewhat beyond me, and I have not an ACS subscription to speed-read the related research, and this is at the limits of what Wikipedia can describe, so I may be somewhat wrong, but I'm still going to try my best to explain the science being don here nonetheless.

Photon goes bonk on a molecule and it knocks an electron free (we can turn this electron into power in solar cells!). Sometimes, however, this electron knocks a second electron free, which is the "singlet fission" process being described (this means we get more power in our solar cells). We want to model this process in various molecules to be able to make better molecules for solar cells.

There's a problem... this is quantum mechanics, of the "start with Schrödinger's equation" variety, which means it's meaty math that's hard to do without powerful computers, and even then, you either have to make big, (over-)simplifying assumptions or deal with small fry. The systems where singlet fission takes place involve lots of conjugated bonds--a giant line of benzene rings smushed together, or maybe just a line of double bonds (the latter is what our eyes use to see light, FWIW). This provides a simplifying assumption for the math.

Now we come to what this paper is doing. This paper is swapping out one of the subroutines for the math with a quantum computer calculation. It's using a test molecule, and comparing the results of the quantum-based simulation with the purely-classical-based simulation. Note that everything here is pure simulation: there's no real, physical molecules being studied!

Because quantum computers that exist today are weak, they are using the simplest possible system for their work--this is the H₄ system. This H₄ is not a model of any real molecule [1]. Rather, it's a reduction of the behavior of real, interesting systems--linear conjugations of orbits--into the simplest possible model, in order to allow some of the behavior to even be studied in the first place.

So, in short, this is a paper that is concluding that a more powerful quantum computer might be helpful in doing the calculation work needed to evaluate candidate molecules that might make better solar cells. They've done this by showing that a quantum computer can indeed do the calculation on a simple model and that the results track existing classical computations (note there's no actual evaluation of if the quantum computer did it faster).

[1] Offhand, I'd say it's not what a real H₄ would look like. H₄ would likely be a tetrahedral complex. But I also imagine it's thermodynamically unstable and would dissassociate into multiple molecules with any number of electrons: neutral charge would definitely go to 2H₂, +1 charge to H₂ and H₂⁺, +2 charge probably to 2 H₂⁺. I've got no idea how the hell H₄³⁺ would break apart, but I have to imagine that one electron can't keep the protons from flying out of the molecule. In no case would you end up with a linear arrangement of atoms 2Å however
I have not. But looking at it, that is clearly not a fit for me.

I've always had a pretty classic presentation of ADHD. Demands were hard for me to comply with, but I never lacked a willingness to comply when I could.

The pushing back against demands that I am describing is a coping mechanism that I find improves my self-control. But I don't avoid demands. In fact I make a lot of demands of myself - as long as they are tied to accomplishing things that I want.

The sgi irix cd's were in their EFS filesystem. It made reading sgi disks on other systems a bit of a challenge.

At one time I was tempted into putting a UFS(the dvd filesystem) format on a flash drive, the theory was it would be a better filesystem than FAT and be readable in any OS. The problem was nobody ever implamented write routines for their UFS implementation, they were all read only. Sort of understandable as the key driver of UFS was a read only medium(the dvd). but it dashed my dreams of using it as a cross platform filesystem.
My mum uses a 2014 ipad air 2 and it still works perfectly fine and even still receives security updates. I don't think Apple needs you to be buying a new ipad every few years. Every time the device needs replacing, its a chance you might switch to Android and stop paying for their subscriptions and 30% cut.

The iPad is just one piece of the complete ecosystem. If they last forever without feeling obsolete, it builds a stronger brand.

Every train needs their own battery, all trains can use the same overhead lines. Plus, in Europe, most rolling stock is electrified anyway, and diesel units are only kept around for a handful of peripheral lines. Germans are famous for not being willing to spend anything on infra, but I'm not so sure battery trains make sense for them. On the other hand, it may make for another nice subsidy vehicle for local industry like hydrogen trains were.
