> More programming languages should be offer support for units, and more program should be using them.

There is some solution for most programming languages:

https://gmpreussner.com/research/dimensional-analysis-in-pro...

How well it works mostly depends on features of a programming language or it's compiler.

That said it's rare for a programming language to have a type system with extra features and unit checking support in it's standard library like F# or GNAT does:

I don't know what the complaint is about. Read after me: desktop Linux. Not clear? Again, desktop Linux. I think that is abundantly clear what counts and what doesn't.
The marketing turbobabble alone is enough to put me off. This is Hacker News not a listicle review site.
* since worldwide direct measurements began, in the '80s. But also, we have no indirect/proxy measurements from before then to suggest that the ocean was warmer before the '80s than it was when those measurements started, let alone now.
I am totally confused, it is documented in the original south korean paper, why anyone would want to rely on such second hand unverified info when first hand info from the original inventors are freely available to everyone?
Do laptops count as desktops?
Can you name another year in which the ocean temperature diagram looked like this? https://ichef.bbci.co.uk/news/976/cpsprodpb/F0A3/production/...
Yes and no. You still need access to red phosphorous which is not all that easy to get hold of.

Since the 1880s (at least ...)

This graph shows how the average surface temperature of the world’s oceans has changed since 1880.

The shaded band shows the range of uncertainty in the data, based on the number of measurements collected and the precision of the methods used.

https://www.epa.gov/climate-indicators/climate-change-indica...

* Sea surface temperature increased during the 20th century and continues to rise. From 1901 through 2020, temperature rose at an average rate of 0.14°F per decade (see Figure 1).

* Sea surface temperature has been consistently higher during the past three decades than at any other time since reliable observations began in 1880 (see Figure 1).

Data from:

NOAA (National Oceanic and Atmospheric Administration). 2021. Extended reconstructed sea surface temperature (ERSST.v5).

Fascinating. How would this affect commercial application?
You know, I do want to pay $300 dollars and carry an additional screen around everywhere I go just so Facebook can show me more ads.
Scheme is not functional per se.

Scheme the language supports multiple programming paradigms.

The culture pushes people towards functional programs,
but having mutation available has always been part of Scheme.

Most Scheme implementations also offer some sort of object oriented solution.
Yeah, what is it with 40 years old people "getting annoyed"? Too many "angry old man yells at cloud" memes, I suppose?
Why didn't Nintendo start porting their games to Windows when emulators became capable of playing Switch games?
The point being, RTSC just tears the floor out on some of the operating costs for it, so since all the control schemes and even a lot of the design work is already established practice, maglev /ought/ to proliferate a lot more quickly than, say, municipal scale fusion reactors.
I guess you're the type of person who's impressed only when it is too late.
Yep.

The moment you install Django, you have to add all the auth stuff to your todo list. If you're not a Django expert then its easily hours or days pointless work.

Pretty frustrating to instantly be given the large and for some people intimidating problem of implement signup/signin/forgot password/reset password and do it all properly, reliably and securely, even whilst Django smugly asserts that it's "batteries included".

You have to head off and find which auth plug in system to use, work out what is still maintained, which provides the features you need and then the task of integrating it with whatever front end you need to present to the user. All this you need to do if you are new to Django.

It's a huge gap in the Django offering, and makes Django look pretty out of date.

Django should come with a built in user flow that allows signup/signin/forgot password/reset password as well as related emails, and it should come with support for json web token and cookie session, plus example UI code for React, VueJS, plain HTML and maybe some of the other common JavaScript front ends too, as well as APIs for other front ends to use.

Why they don't provide this is hard to understand. It's just instant makework for developers.

Either this or drop the "batteries included" thing.
For a memorability, I would prefer using domain names which is invented for the humans.
Not really a gamer (certainly not for horror games) but I might take a look at this. Thanks for the recommendation.
Doesn't HTMX work via HATEOAS so would require a full RESTful backend?
It can matter a lot. The arrival of HIV in 80's changed suddenly how people interact with sex forever. Specially one night stands and casual sex. I can do some damage control about who enters in my partners list, I don't have any control about who were in yours so yes, sometimes it matters.
Modern pharmaceutical financials are the equivalent of taking hostages one-by-one and letting them pay for their lives. There is a fantastic book by Marcia Angell that details this.

Ask HN: State of the Art in Internationalization
Hello HNers,

what would be the state of the Art of I18N and L11N? Does one use AI today? What are SaaS companies one would use and software stacks, e.G. for iOS and Android, Flutter and native apps?

Would one do L18N on the backend and send localized text to the frontend as part of the API or keep L18N in the client?

Thanks for all pointers!

Finding a partner isn't actually that hard:

1. Don't be an ass, be kind and respect people

2. Be polite, accept a no as an answer

3. Accept the universe is not owing you anything, let alone an initimate relationship

4. Be open minded

5. Accept yourself as you are and others as they are

It really comes down to number one, don't be an ass.
I am assuming those numbers were self-reported. Happy to be corrected otherwise.
Several other protocols solve this in a layering agnostic way by simply having a header length field. The header bytes can then be copied without any understanding of the format. This is even how IP's own ICMP protocol knows how much of an IP packet it should (at least) include in an error message so that the sender can know what triggered the error.

TCP, UDP, ICMP and IP were all designed contemporaneously; UDP fragmentation could also easily have just been specified for. It's just an odd regrettable quirk.
Oh yeah, the commercial "doers" are happy to have a go once academics have slogged away at the hard, risky, expensive, and often thankless trial-and-error before the discovery. Not to do down the people in this particular example, and I'm happy to assume they aren't claiming any credit they shouldn't, but the dichotomy really isn't as you make it out to be.

Evidently they did have sufficient evidence. With such a big potential payout of such a world changing material, others have invested a few days of time into verifying their rushed paper and indeed their weak evidence was enough.

Again, with a payout so big and ease of replication fairly low, the evidence doesn’t even have to be that convincing.
Twitter isn’t loading at all for me at this moment. No idea if it’s me, or twitter or being logged out or logged in or what.

That's a bit different, the issues with trauma from sexual abuse can lead to sexual promiscuity but it doesn't follow that having multiple sexual partners means you are suffering trauma from sexual abuse. And neither imply what an individual would be comfortable doing in a sexual relationship.
That's not entirely accurate. For my understanding, it is a private institution which employed the individuals who made the discovery. Some of whom have alternative backgrounds in academia, and some of whom have it in industry.
Standard Notes has a selfhostable server and clients for mobile. Beaver Notes seems to be confined to one desktop device.
As engineers we are given building blocks that we can build things from. Iron, steel, copper, plastic. Every once in a while a new building block arrives. It takes a while for us to figure out how to use it. But when we do, the world changes.

- batteries + touch screens => iPhone

- batteries got better => Tesla

- reinforced concrete => pretty much all the worlds buildings and bridges

- neodymium magnets + gyros => drones

A room temperature superconductor... well, that changes things on a completely new level. Order of magnitude smaller losses plus order of magnitude higher magnetic fields? OMFG can we build SciFi things from this if it pans out.

So yeah - we are in a hurry. If this pans out, there will be a massive shift in how pretty much anything is made. And the reward for the people who can figure it out first are insane, in terms of potential value created.
The problem of Discord is discoverability. Is you project known on the web? What about resources? In the end you might develop for a few other developers, but only those that happened to run into the correct invite links.

Everyone else will believe your project is dead.

I think the difference is that, certainly in Canada, the top universities have grown their enrollment as the population grew (uoft increased degrees awarded around 30% from 2011 to 2021 for example from:https://governingcouncil.utoronto.ca/degrees-diplomas-and-ce..., I am sure enrollment is way up recently as well because it looks like there are 90k students enrolled and I swear that number was more like 65K 4-5 years ago, although I don't have hard data).

Harvard, on the other hand, lets in a few thousand students a year and I am pretty sure that has barely changed for decades. This changes a ivy degree from not just a good degree to a good degree with a high elitism and increasing scarcity associated with it.
Is a similar thing called a window in TCP?
> What a complete clusterfuck. It's unbelievable that in 2023, a company of Mozilla's stature appears to have no proper processes in place for handling serious security vulnerabilities even when they are being reported to them (for free!) by cooperative third parties.

While I agree with your sentiment here, it's not exceptionnal at all and I've seen security researcher complaining about the same thing comming from at least Intel, Cisco and Google[1]! And I wouldn't be suprised if you could find example if that regarding Apple and Microsoft as well.

It is. For airplanes it's probably better to lose 30% of the energy and synthesize carbon based fuels.

Hydrogen is still useful as a store of energy to smooth out seasonal variations in solar and wind production though. On a large scale it's more difficult to store than natural gas due to embrittlement but not impractical.
While you could make a case that it is convenient short-term, it is very cost-ineffective.
Doesn’t ring true for me at all, academia is many things but if your supervisor is onboard, you can generally do anything.

According to this, breakeven can already be achieved. Rather funny how this is a highly advanced research topic and a mistake like that could take place (if real).

You can optimize this with the right electricity contract. Time of day pricing ("dynamisch tarief" in the Netherlands) combined with charging during the cheapest times can make a big difference. And as a bonus to society, you help to balance the grid.
"Depending on voltage level and construction details, HVDC transmission losses are quoted at 3.5% per 1,000 km (620 mi), about 50% less than AC (6.7%) lines at the same voltage."

https://en.wikipedia.org/wiki/High-voltage_direct_current

This seems pretty significant. We don't have much losses because we don't transmit energy over long distances. But now we could.
I agree, but I just think that doesn't preclude some healthy gratitude for the luxery and freedom we are enjoying these days. A freedom many, many people gave - and continue to give - their lives for and not just in war.

Can't we do both? Appreciate the progress we made, "we don't have it as bad as the last guy", and also looking towards improving even that? Wholesale dismissal of the entire edifice is IMO not the way though.
The mind ceases in deep sleep as well. Neurons aren't firing or communicating, just turning on and off in continual waves.

The story goes, some professor had a theory in 1999 that was rejected by the mainstream regarding creating superconductors. He passed away and as a dying wish asked his students to continue the research work and develop a theory for why it works. The students unable to get “academic” funding set up a company and got funding from industry to do their research in 2017 and the rest is history.

It’s very hard to redeem academia in this example.
I entered junior high school in Southern California in 1969. At that time, all of the girls took home economics and all of the boys took shop classes: about eight weeks each for woodcraft, metalworking, electricity, drafting, and print shop. In print shop, we had to memorize the layout of the job cases and be able to sort the type back into the proper locations without referring to a chart. The final project was to set a few lines of type and print it on a small rotary press.

I don’t remember the layout of those job cases anymore, but I’m pretty sure it wasn’t this California job case. I don’t think the capital letters were laid out in alphabetical order.
Good advice, I thought I would do exactly that, and ended up at a startup. Looks like they are not trying to achieve super-scale, and that's good. Perhaps we're mired in the old ways of thinking, where we over-optimise for everything, even though we don't need it (nor indeed, we ever will).

Perhaps I'm an attitude-adjustment away from it. Time will tell!
Is Saturn a failed gas giant?
Exactly, hindsight is 20/20. This reminded me of a friend of mine fixing a coding issue that was impacting performance. Fixing it saved a lot of money and it was the initiative of the engineer to bring it up. The response of the (at the time) CEO: well, why did you not fix it earlier?
Anything with a finite (200 is small even) number of units misses the algebraic structure of the problem mentioned in https://news.ycombinator.com/item?id=36988497 wherein multiplying|dividing two things gives you a (potentially) new unit which implies an open ended "space" of units.

To be concrete (hah!), in C++ a template meta-type with 12 signed integer parameters (6 numerators & 6 denominators for rational exponents of SI base units) might be one way to model it.

Unlike C++ template stuff, Nim macros (like Lisp macros) makes metaprogramming more like procedural programming - just against abstract syntax trees. I think that helps to shield some of this type complexity from users, but the documentation README https://github.com/SciNim/Unchained does better job than I can in an HN comment.

Of course, for unit system conversion, the number of dimensions (6 in SI, 3 in CGS/Gaussian) changes. So, for full generality you need compile-time (if you want static type integration/CT errors) linear algebra over a rational field (at least & conventionally) to project|inverse project. That might be theoretically possible in C++. I would think it very un-fun and unlikely to ever have been done. There's probably a Mathematica package, though.

EDIT: It seems that mp-units mentioned in a sibling comment has some rare support for varying unit systems (no GR or Planck ones, but at least "natural" & "hep" & not sure about system-conversion or just system-use). That lib also leans very heavily on many very modern C++ (C++20 & beyond) features, has constexpr everywhere in use cases. I am not sure I would say it shields users wonderfully or makes it seem like units are very ordinary types. Just looking at mp-units/example/VARIOUS.cpp makes it look syntactically very noisy, verbose, and a lot to learn.
Because too few people are participating.
To state the obvious, everything that's in a movie is a deliberate choice by the director. Hitchcock spoke about "playing the viewer like an organ", i.e. manipulating the audience by what is shown, what is not, what is revealed, the order of information being shared with the viewer. Sex scenes can certainly be in a movie for character development, but often are just there to make the audience horny & increase the fun factor and therefore positive experience of the movie. Calling out Nolan for his sterility in movies misses that point; his movies are ideas with stories attached, vs say Bay or Bruckheimer, whose movies are more deliberately products designed for the mass market.
It would be interesting to see this chart start much further back, such as when most humans were hunter-gatherers. Yes, working hours per week have declined since the beginning of agriculture, but there is evidence that humans worked much more as farmers than as hunter-gatherers. For example: https://www.cam.ac.uk/research/news/farmers-have-less-leisur....
My dad must have had to memorize the order of the boxes when he took a printing class in high school because I can remember he would recite it to me when I was a little kid. Thanks for the memory!
As I understand it (not an expert) superconducting qubits are strongly impacted by temperature. So they're typically operated at sub-Kelvin temperatures, using liquid helium. Worse yet, they need unobtanium: helium 3.

With the plague of 16:9 screens, that began around 2008, on cheaper devices often coming with a resolution of 1366x768, vertical screen space started to come with a premium.
What does that mean for people with mechanical hearts? or their hearts were replaced? or isn't human? or were resuscitated?
Having multiple groups document and share their progress while attempting to replicate LK-99 is exciting and it captures people's imagination. People want to see LK-99 being replicated by multiple sources. Aside from that, as I understand it the information in the original South Korean paper leaves out a lot of details on how to fully replicate their findings.
Good insight. I am into therapy and have been for a while. I don't intend to stop, because I see the positive impact it had in the other areas of my life. Perhaps it's time to address the work thing; it's something that didn't take priority so far.

And yes, MORE people should go!
Agreed. Rather maybe spend time on your UX and ensure that the form is understandable by the user. And by deploying closer to the edge, the latency should be pretty low.
You are not wrong. I certainly was no fan of the old twitter’s ultra woke circle jerk and bullyism but you could at least mostly ignore it and the verified accounts were actual verified people.

Today the misinformation and shitposting crap is impossible to avoid, the top comments are invariably random 8 dollar people (?) that add little to the discussion and porn bots / onlyfans all over the place.

On top of that it seems there might be a bias in the accounts that get selected for payouts and there is indeed quite the incentive for ragebait there.
not sure what you are saying. other labs are trying to replicate what Koreans published and are documenting the their process of replication
Can I ask you something? Assuming you didn't just radomly stumble over HN, and this submission, ehy do you use a newly created account for this discussion?
I recall using it for fireworks recipes. Good thing we controlled access since then; otherwise people would be making drugs with it all over...
He’s replicating a cutting edge material science in his garage. People are celebrating the optimistic spirit of Americans. The indomitable will that this country encourages and the sense that anything is possible if you’re ambitious and smart enough to pull it off.
World first replication was done by Iris Alexandra using her own accelerated process and there is no way Varda Space could have beaten her.
In my opinion if people responsible for the choice of such and not another metric realized it will mislead the clients, then it was a fraud. You can do a lot of philosophical gymnastics proving fraud or no-fraud, but in the end of the day you're communicating something to your clients, and if you deliberately confuse them to think your product is better than it really is, is a fraud.

So it probably was a fraud, by my standards.

I'm considering buying Starlink access, but now I have to rethink what it really offers - maybe they use some different than common metric, which is 'technically true' but miscommunicates the actual performance?
Does anyone know of something similar but targeting FastAPI and SQLModel?
Do you mean closed source software? Because that would rule out Hackernews. But I agree on the principle. Maybe it's the type of discussion. I would be happier if this very exciting superconductor story was unfolding somewhere else than Twitter.
My boss did that 5 years ago. He almost died before adopting it.
Omg, that does bring a different perspective. I've heard of the dreaded broom cupboard and you're right, I don't want to go near it.
We're in a hurry in the sense that we don't want to leave investigation of this on the back burner for a few months, but we're not in a hurry in the sense that it's going to make any difference in practice whether a lab group reports today that they've reproduced it, or takes a bit more time to be careful and reports more thoroughly in two weeks time. Any first mover advantages are likely to accrue to the groups who come up with a reliable reproduction method over the next couple of months, not to the ones who send out the first press release and twitter post this week.
In this brave new Twitter-y world, if the Twitter link loads at all (hardly a sure thing lately) it'll only show the tweet without any replies, unless you're logged in. Nitter will show the whole thing (it's ultimately dependent on Twitter so may also be broken, but in several recent partial Twitter outages nitter has been usable while the twitter web UI was not loading).
