Ask HN: If Argonne replicated LK-99, will they keep the results classified?
It's been awfully quiet from the team at Argonne. What's the likelihood that they replicated LK-99, found that it is indeed superconducting, and are quietly trying to optimize the synthesis technique... all while keeping it secret and potentially classified?
Badly written comment, please ignore.
You took an Uber overnight from DC to NY? That's wild.
Really cool, I could pair it with some ocean or river noise from mynoise & it will be a nice things to have on a separate screen while working.
I'm sorry, but what's hard to say about "all floating point arithmetic operations can contain errors". It's such a simple statement, that every developers learn in CS 101, that you don't even need to understand the reason to remember.
Fully agree. If the electorate can’t manage to get rid of this freedom constraining government in the next election then the country is probably a write off. At least it is hard to imagine how we can recover from another government like this.

Who cares, none of those cause anyone to murder, just like race doesn't.
The article on question here is literally about prostitution. Sex can be bought for resources, people are selling it - the world's oldest profession.

It is also cheap.

So the notion that the problem is "men who will never have sex" is fairly obviously false.
Love it - an excellent solution for a local problem. Sounds far more optimal for you guys than having government involvement.

I consider that fine evidence that we over-regulate in some areas. I reckon there’s also a lot of evidence that we under-regulate in others. By contrast, I don’t think it’s evidence for a general proposition that any reduction in regulation is a priori a good thing - despite what the Murdoch press would say.
It's particularly bad when it comes to treating women.

Doctors tend to believe that female patients exaggerate pain in comparison to male patients, in accordance with stereotypes that portray men as "stoic" and women as "emotional". The bias is systemic, with female doctors often assuming the stereotype too[1].

You can trace this bias back through medical literature which (often subconsciously) reiterates these stereotypes[2]. It shows up in many statistics, such as the difference in wait times for analgesics: women reporting pain had to wait an average of 30% longer than men.[3]

But a key cause of the problem is worse than just assumption of stereotypes: it's that modern medicine still knows far more about men than it does women. For centuries, the primary medical research and literature was done by men, about men, for the treatment of men. Most of the clinical trials performed in the 20th century enrolled far fewer women than men, and often _none at all_.[4]

Of course, gender is not the only bias that shows up in medicine. Age, race, (dis)ability, body shape, and economic/social status are all useful factors to keep in mind when considering why certain people, even entire sectors of society, aren't getting the treatment they should.

WONTFIX sounds so final.

Though, reading the closing comment, this is really CLOSED-WONTFIXYET, as in no plans.

Maybe it'd be nice to introduce a WONTFIXYET. Might be useful to fossick among features abandoned that someday become feasible.
They are bound by regulations and liability, your typical GPs and even the specialists can't greenlight experiments outside of big research hospitals. Medicine and clinical diagnosis are heavily regulated. That's also why you rarely see single author papers in practical clinical medicine. Doctors are busy people, with horrendous work life balance. Most software engineers have it way easier, you get to choose your tools and you get to choose where you want to work. In the business of software engineering, a sufficiently senior engineer can get away with a lot of nonsense without risk of lawsuits.
Depends what you mean by suitable. If you run the service as a new user, it's more secure than running without a new namespace (you're isolated from other apps) and potentially less secure than running on host (one more layer of indirection for system resource access).

Since in reality most attacks will be against your app itself before the attacker has direct access to syscalls, I see namespaces/containers as extra protection.
This is very cool; I like it a lot. It's visually striking, and if it's sonically striking / it works, I could see it in people's homes or in concert halls. The article says it's "lighter, easier to move, and more convenient to fit in the home." Might be a piano game-changer if true, but given that there is no video, Whipsaw doesn't seem to have built it. Maybe that's the next step in the works.

And yes, there's a decent bit of "artist's statement" patois in the article, but that's sort of expected from designers.
I don't believe it is possible under US law to "relinquish all copyrights". Merely asserting something is in the public domain does not make it so.

For instance, I could write a book today and do so... and people are probably safe to do what they want with it. Then tomorrow, when I croak, my family still retains copyright for the next 95 years. They might decide that this is their golden ticket, and everyone who continues to publish it would be in trouble (past actions shouldn't be sanctionable... while alive, I essentially gave license to do so).

Even if something is legitimately within the public domain, the courts (in the US) have at times decided to yank works out back out and give them as gifts to the various big licensing regimes (ASCAP, if I remember correctly).
This is such an HN comment ;)

Sibling comments are correct that weighted keys, graded hammer action, etc are all much better than a plastic level but still don't have a proper sense of touch that is linked directly to the sound.

It's not even a matter of training with a particular touch and being used to it - the link between the body and the sound is incredibly important and mechanical means of making the link are still far superior.

EU Late to the Quantum Party, Report Warns
If built to spec, then the various container technologies in the kernel used together are theoretically secure. It closes all of the holes that we know about, aside from a few trivial things like the container spying on process id numbers on the host, and of course the vast potential to accidentally misconfigure it.

However, all this code is quite complex, and the kernel and the software ecosystem are lacking in having a layered approach to security that goes all the way down to the low-level nitty gritty stuff. For example, kernel memory structures are not robustly protected against the usual memory exploits, and there isn't as strong W^X protection as desired. Windows, in contrast, is able to provide layered security through a variety of approaches, including running the entire operating system in a virtual machine, with the host ensuring integrity of kernel memory. These sorts of layered approaches to security are desirable because there will always be defects in any complex software.

Side note: AppArmor and bwrap are distinct. Bubblewrap is a relatively simple userspace program that makes use of existing kernel containerization features (the same ones that Docker/Podman use), whereas AppArmor and SELinux are security features that are patched into the kernel itself. AppArmor and SELinux have made some progress in adding layered low-level security to the kernel, but it's not particularly impressive. Bubblewrap has done great work in exposing the kernel's existing tech to users, but they are not fundamental improvements to the kernel itself.
It has tons of annoying quirks, but I couldn't imagine running a DBT project without it: https://github.com/sqlfluff/sqlfluff
This is an argument popularized in the book “Freakanomics.” The authors presented data that correlated the legalization of abortion to reduced crime rates 16-18 years later (young men disproportionately commit crime, especially violent crime.) This was ascribed to less unwanted children being raised in bad circumstances.

Later research showed a (I believe even stronger) link between leaded gasoline being phased out and reduced crime later. Environmental lead is well known to have psychological effects, including an increased propensity for violence.

I think the general belief is that environmental lead had the stronger effect, but legalized abortion can’t entirely be counted out, but I’m hardly an expert and I suspect it is all still under debate.

Been taking my 2 daughters to a pediatric dentist since they started about to have teeth. Our eldest had cavities, which we could visually see. We were very careful with the youngest, brushing and flossing more. And well, she has even MORE cavities. They are between the teeth - which I guess, well, trust the experts. The fillings expensive aren't that expensive as dental insurance covers it.

Whats expensive is the nitrox oxide which the kids require because they can't sit still. Or maybe the dentist isn't good at her job and can't do it without it. This is 100% out of pocket. Insurance doesn't cover it. and the dentist can set whatever the price they want. This costs $100.

The kids for sure, fight and the dentist is in there trying to get them to open their mouth. Well, my youngest had 5 cavities, and only 2 got filled because of her small mouth and not comfortable.

You know what that means...more money to shell out because now she needs sedation. And that's $400, for a little drink that's like "Benadryl" as the dentist said...and it barely worked. The last filling couldn't be filled.

If we were more knowledgeable we would have just given her melatonin before the first procedure as that's more effective in calming her.

Oh and I found out the dentist is closed on Fridays. Must be nice to be able to charge so much you can pay yourself, staff the needed salaries and only work 4 days.
Victimization surveys also corroborate these proportions at least for attempted murders and other violent crimes.
But it's diamagnetism none the less. Which is the entire point of the argument against LK-99.

IMO median food in NYC is much lower quality than what you can get in SF. It just is unhealthier and less fresh. Maybe for pizza or fine dining NYC is better but SF takeout just seems much more nourishing and higher quality. I’ve also been served really terrible food in NYC on several occasions, which has never happened in SF.
>>> keep your modules (functions, classes, components) deep: small interfaces packing significant functionality. The idea here is to give users of the module the biggest benefit for the least learning.

Low to none. Its federally funded, it and this is not their modus operandi.

I think it's actually insulting to them as government funded scientists to imply it.

The most likely reasons for them not publishing is that they don't yet have enough data to meet their internal review bar for going to publication and unlike the other people, have little to no interest in trashing their reputation by inflated early claims or leaks. The second most likely reason is they have unclear results and so are seeking internal replication. If they have anything interesting to communicate about work in progress they will do it scientist-to-scientist, not in public.

Here is where they publish their IPR

TL;DR the pace of reporting in this space is stupid. Normal science publishing speed is slower than twitter, for good reasons.
PRC will remain effectively closed to talent, so they have to produce their own and what they lose to emigration they hardly get back. Put it this way: a whole generation of Chinese previous STEM students from top universities are now in upper leadership positions...in the USA. It remains to be seen if similar younger talent now will grow to that under the Chinese 996 system.

> Denying US PRC talent isn't about crippling US talent procurement, which US immigration policy does itself. It's about retaining PRC compatible talent - as you say, US can draw from English world, PRC largely rely from drawing from within. US denying itself large segment of talent that only benefits PRC to retain is a relative win. It's like the one area where could US win by default but chooses to cede.

I don't know how you can say this with a straight face when PRC immigration policies are much much worse. The USA has a system that is hard to get through, sure, but many many people get through it with permanent residency and citizenship at the end. Very very few get through the PRC's immigration system, even of Chinese descent, as you say all China can do is retain talent.

> It's like the one area where could US win by default but chooses to cede.

Again, the fact that the USA grants 740k green cards a year is not small potatoes, and many of those are in tech, high level STEM positions of talent. When I worked in China, I was the only foreigner in my team, maybe a few foreigners in our entire lab. Now, I'm working at Google in the USA, I can count the born-in-America types on one hand, most of my coworkers are immigrants, a long with a lot of young Chinese new grads. It doesn't feel like much as changed on the ground, but ya, Indian immigrants are gaining lots of ground over Chinese immigrants in leadership positions and such, which is something I wouldn't have predicted 20 years ago (look at the top CEO positions).
Well the article includes things like lost productivity due to sitting in traffic, so I think it's fair to point out that there's lost productivity due to train delays.

The MTA creates a lot of its own issues though. The bare minimum for a public transit system, in my opinion, should be reliable estimates of how long it will take you to get somewhere, but for non-rush hour trips estimates on the MTA are pretty hit or miss. I've heard this is because the switch operators are all running on some ancient system which is impossible to computerize, but for a system that has tens of billions of dollars in funding I find it hard to buy that they've exhausted every possible option.

Unless you believe yourself to speak for America, I very clearly didn't say that.

Institutional racism, drug wars, three strike laws, mandatory minimum sentencing, relentless propaganda and demonization, underfunded schools, leaders smeared and assassinated, etc etc etc.

And now you, you specifically, are blaming it on "their culture" and acting like it's a big mystery. Ugh.
Early Hotline was amazing from a hacker community perspective - I ran a series of hotline servers off of dialup, and then was able to get some hardware on my high school campus and have a server on our T3 for all of a day or two before our sysad called me in and said that hypothetically, if someone had a hypothetical Performa plugged in and was hypothetically to turn the hypothetical thing off that day, nobody would get suspended, and then that hypothetical someone could hang out in gap periods or after school and get paid to do actual IT work for the school department, learn a ton, and kickstart a fairly decent career hacking on stuff and getting paid for it - and hypothetically help run the official unofficial school Hotline server.

Super grateful to that dude to this day, I hope I'll get the chance to pass it on.

>regret not doing an electrical engineering elective at uni when I had the chance.

This notation would not liklely be in the curriculum.

Mainly an artifact of the pen-plotters that were used to print the early digital schematic drawings. Greek letters were not in the character set and at the same time they didn't always print a decimal point very legibly, so the R (multiplier=1, or other multiplier like K for kilohm) was used in lieu of an ohm symbol and it was inserted in the specified component label in place of the decimal point.

Simple example amplifier:

The lower case u substitutes for the Greek micron.

So 7500 ohms would be drawn simply as 7k5.

Ironically, using your system’s math libraries will probably make replicating floating point results harder. Especially on macOS. Accelerate is a curse.

I disagree with your gloss of Kahan’s philosophy. His approach is more along the lines of “do not waste precision”. But this philosophy is not the complete truth; as close as I can state it briefly, my modification would be “do not waste precision that may be needed later”.
This could be quite useful in a CS course on containers.

Naturally, people who've always lived in hot places for centuries have more well-developed and thought-out ways of dealing with heat.

The trouble with 'modern' air-conditioning in conventional housing is that it uses energy to produce waste heat which is also absorbed by the environment. Then we're building up the thermal capacity of our surroundings (asphalt, concrete, roads) ... a bad idea. In cities, it 'keeps on giving' all night.

This technology, used in Africa, Asia and India has been around at least 1200 years: https://en.wikipedia.org/wiki/Windcatcher

The coolness of the Earth beneath our feet never seems to be advantaged by cities looking for solutions. Cool thermal masses are often found underground. Those of us who live in homes with basements have a thermal resource that's very welcome when upstairs temps rise above 90F/35C.
The failure of the scientific community in not continuing to pursue the goal of levitating increasingly large fauna can not be overstated. It’s 2023 and we’ve devoted untold billions to finding the Higgs boson, to landing and reusing orbital rockets, and yet, I can’t go on YouTube and find a video of a levitating giraffe. Sad.
This is absolutely not the case for most physical simulations where the significant digits are more important than fixed decimal accuracy.
I agree, there's no point being mad at it since there's good reasons why it ended up this way
Yes. ICE's have an additional CO2/NOx tax though.

huh, i didn't realize until just now that dc had arrays, the : and ; operations

i guess that makes it a far more practical platform for applications programming than i had always thought

unfortunately afaik it still can't take character input. i guess you could pipe its input through something that converts it into a stream of numbers?
Sadly seems like the 90’s experience was so much better before corporates and brogrammers ruined things.

The bones were found in a very strange location "the last place you'd look" and it didn't make sense why he'd end up there - the video provides (during a walk to where the remains were found) about "how would an experienced hiker end up like this" and basically lays out how each step of the journey "made sense" and the last attempt was based on a relatively low detail map - he was heading cross-country to try to get to a road in the shortest distance possible.

It also drives home how you should not deviate from planned travel and always try to back track, but I digress.

I suggest to look up his trip up from Mexico, following the migrant route. For a different view of the same trip, his travelling companion (automous something) has his own channel.

Hobo Shoestring has an interesting channel also, albeit with a home base. You'll learn a lot about trains, and hobos' most hated adversaries, the 'homebums'. :D

And of course, there's a 10x hobo, in stobe-the-hobo (RIP), well worth watching all his videos.
All of those things plausibly lead to cultural differences. How else do you get from those things to “elevated homicide rates” without traversing “culture”? Feels like you’re violently agreeing.
People you are talking to only care about image, they just buy into the macho image projected by marketing.

There are many tradesmen, farmers, etc who would love to buy one of the small trucks that used to be available. They are great for tossing tools into and going to fields, work sites, etc. But trucks with that wheel base now require an efficiency level that isn't feasible. Many have resorted to using UTVs in their place where it makes sense, but those can't completely fill the gap since they aren't street legal.

Regulations always have intended consequences.
I broadly agree with all the points here. I guess the author reasons about code the same way I do, which is interesting. The exception is the bit about vertical space - we effectively have infinite vertical space and limited horizontal space, I think we should trade them off accordingly.

I especially agree with the idea around "code locality". I find the easiest code to deal with are those that doesn't require me to understand how everything works, to understand how one thing work.
Big-number libraries break down if you want to do anything other than be a 4-function calculator (and honestly, even division can be questionable, since some big-number libraries use fixed base-10 and thus even ⅓ isn't accurately representable). Want to throw in a call to sin or exp? Your only realistic option is some sort of floating-point, and that quickly boils down to "do we use IEEE 754 single or double precision? Or are we in the rare case when we need quad [1]?"

[1] I believe the biggest use of quad precision is evaluating the accuracy of double precision arithmetic.
