Of course, Galois and his fatal pistol duel were a long time ago, soooo, there are many polished presentations of Galois theory.

E.g., in the abstract algebra text by I. N. Herstein can learn the basics of Galois theory in a few hours of study.

Apparently the idea of using abstract algebra, especially fields (each of the rational, reals, and complex numbers are fields but not finite), for applications, especially to error correcting codes and, eventually, cryptography, date from Hamming back at Bell Labs.

In college and grad school, I got dragged into finite fields and related topics over and over. I was too patient and tolerant: I just don't like that math. I DO like linear algebra, especially for its connections with Hilbert space, differential equations, the math used in Maxwell's equations, differential geometry, optimization, relativity theory, Markov processes, and more but somehow I just don't like cryptography and error correcting codes. Back in college one of my profs just observed and remarked that I'm an analyst and not an algebraist! So, this situation may help others here at HN: Some people like math analysis while mostly others like math abstract algebra!

Still, just for Galois theory, if want to learn it, then can do that in a few hours!
If a structural engineer points out that a bridge is unsafe, you don't call them "engineerbrained" and gesture at all the motorists still using the bridge. Why do we accept this bollocks in software engineering? Meta are not trustworthy and it's reasonable to want nothing to do with them.
> If a rail is built successfully, there will be an extraordinary increase in transportation abilities — saving commuters time while reducing environmental harm.

This high-speed rail is intended for people getting between home and workplace on a daily basis?

Edit: I'm not asking whether it can be used for daily commutes, but is daily commutes the reason for building this? Or what is the reason?
Always fun to see executable specs. For a bit I was experimenting with using F# to write the WebAssembly specification. We ended up using OCaml.
It’s the early blips of an eventual space faring civilization.

The signal might propagate and alert other intelligence that we are attempting something challenging.

Hopefully they send help.
There are (at most) 2 of those locations in the entire US PNW... downtown Seattle and Downtown Portland. And frankly I'm not sure Portland counts.
There’s a little problem with that. You want people who live close but not directly near one of the stations to also drive and park and take it. So you do need stations continently outside of the super dense metro area.
The space industrial complex would pollute a whole lot more than today, and let’s hope space tourism it’s not something too feasible, aside from stroking egos it wouldn’t do much, space is very human unfriendly after all. I for one hope we move slower not faster.
> The site’s now characteristic tone of performative erudition—hyperrational, dispassionate, contrarian, authoritative—often masks a deeper recklessness. Ill-advised citations proliferate; thought experiments abound; humane arguments are dismissed as emotional or irrational. Logic, applied narrowly, is used to justify broad moral positions. The most admired arguments are made with data, but the origins, veracity, and malleability of those data tend to be ancillary concerns. The message-board intellectualism that might once have impressed V.C. observers like Graham has developed into an intellectual style all its own. Hacker News readers who visit the site to learn how engineers and entrepreneurs talk, and what they talk about, can find themselves immersed in conversations that resemble the output of duelling Markov bots trained on libertarian economics blogs, “The Tim Ferriss Show,” and the work of Yuval Noah Harari.

wow nailed it
And on top of that there are literally dozens of other exceptions the courts have come up with over the years. I was forced into slavery by the government in the USA, due to exceptions that allow the government to force unconvicted persons into labor in certain circumstances.

I think the tracks are the most expensive part though, no?

Although I'm not sure if you mean the physical tracks are in poor condition or the layout. If it's the layout, that's not much easier to fix than building a HSR. They may not even be able to fix the railroad company owned tracks?
They were selling doubleheader tickets to these two movies where I am from.

I still don't understand it - is there really that much crossover between the audiences, or are people really that bored?
> The "shallow platitudes" cut through the BS.

Shallow platitudes are themselves BS - populist soundbites that can be weaponized both for things you like and things you don't. There are better conversations happening elsewhere in this very comments section that don't have to lean on them as a crutch.
Yeah like a creative destruction type thing. I think the point is to destroy whatever this is by the process of evolving evolution via capitalism’s ability to rapidly push forward tech which creates genetic/dna synthesis which evolves into post-humans.

How can we stop a force of nature?
I am not sure it is useful to transport 2000 kg of metal occupying a half of a rail car, just to move 80kg meatbag for a distance of 173 miles.
> An average EV uses 50kg of Lithium.

And And additional 50 tons of fossil fuels to build the car. And still uses tons of fossile fuel when consuming electricity, because that's how we make it, and renewable aren't gonna replace it entierly, as you can't realistically go above 80% wind and solar (and even those 80% are a theoretical limit, and reaxhing it is a massive deal…).

The only green car is the car you dont drive (nor own).
My initial experience was I had to access through an app on my phone. No thanks, I am not interested in contributing to the surveillance economy anymore. No data-vacuuming apps, no WEI.
and it looks like they have 7 high speed lines coming from Paris. Seems the PNW could afford 1.
Yeah, Netflix pays this much not because it will replace a near minimum wage writer but because optimizing their advertising tier by 1% will pay back more than the PMs salary every 30 days.
actually the extension targets one specific site and they wouldn't really be happy about it

it's nothing nefarious but it's adding a feature that they refuse to add to their websites because it could hurt some of their numbers
I don’t know the answer to either of your questions. Is track more expensive than new high-speed trains?
Or he is playing the victim card because he knows his selfish actions are enriching himself and his oligarchical employers while the rest if us suffer and lose more agency.

Most of the problems seem to stem from unfamiliarity with fediverse. Except this:

> Personally, I like that people second-guess themselves a bit, and self-limit what they post, to some extent at least.

The given examples include badgering people to put content warning on discussions about anti-trans legislation or pictures of reptiles. That feels more like thought-policing. If people are so sensitive, they probably shouldn't be on the internet, much less the social media. This though, seems like them saying "Nobody wants to hear what you have to say. Go away!". It doesn't just feel insensitive - it feels like bullying of new users.

I have been on the Fediverse for a while now. I have had nothing but respectful discourse from others even when they disagree with me. However, if anybody bullied me like this, I would rather just call them out for it than put a CW on my content.

> At the other extreme of the spectrum, we would get Eternal September.

I hear you when you say Eternal September would be the extreme. But Eternal September is really only applicable to shared communication spaces like forums, Reddit or Lemmy. Mastodon is more of a personal space akin to personal blogs, Twitter or Facebook. The quality of your Mastodon feed depends on who you follow and not on everyone around. The quality of posts should be allowed to vary with each individual - except in extreme cases. Let people be themselves in their own spaces.

The recent influx of users to Mastodon has actually enriched my feed. There is always interesting content and new users to follow. I personally am happy with all the new users.
The problem with only relying on asyncio and multiprocessing is that they only implement per-process concurrency and parallelization per-process.

Threads let you use the same unified abstraction for parallelization and concurrency. They also make it easier to share state with parallelization (no need to go out of your way to do it) at the cost of requiring you to think about and implement thread safety when you do so.

Also, with no-GIL + threads the computational costs of creating and maintaining a parallel execution is much less vs multiprocessing. And data sharing and synchronization are less expensive.

What LMAX is doing is really just an overhyped way to speed up producer-consumer models. It might apply to your use case but it’s not the only reason you’d use parallelism or concurrency. I don’t even understand why they are claiming it to be an innovation when it’s just using a LockFreeQueue implementation within a pre-allocated arena? You also can’t synchronize with their implementation, which sometimes you really need to do. Not a silver bullet

Wouldn’t surprise me if I did something stupid like that.
This seems somewhat delayed, and it may be considered too little, too late. Python community had the chance to leapfrog and embrace alternative concurrency abstractions, such as go routines etc, but it appears that this opportunity was not fully utilized.

After enduring the arduous process of migrating from Python 2 -> 3 and navigating the complex world of dependencies, my hope is that we won't encounter another nightmare of dependency management, forcing users to choose between GIL and no-GIL builds.
They allocated $150M according to the article.

I can't see that being enough to even break ground on a single mile of track.

If California boondoggle is any indication, it will be enough to staff an army of middle managers, bureaucrats, and environmental impact and DEI staff for a year, and, of course, pay out some political kickbacks.
I think the wide variety of payment scheme is the main reason for buying luxury or premium items from lots of consumers. The monthly payment is so low they don't feel it unless they lose their jobs.
Perhaps you'll be shocked to hear that countries like Sweden have HSR despite not being particularly densely populated? It's absurd how much money is poured into roads and yet never attracts the same criticism.
(1) they were not car owners

(2) actual car owner came forward and claimed he was carjacked

This seems like a pretty good reason to at least get them into custody to prevent them from fleeing.

All your hopes of GIL free code ruined by a GIL requiring left pad dep buried deep in the dependency tree.
It doesn’t know the answers are correct. I intentionally give it the wrong answers. Sometimes it realizes my answers don’t Match what is most common. So It doesn’t give me hard questions then. And doesn’t give me more than one prompt.

I remember using the same type of desks in Italy in the 90s. Minus the ink well, of course, because we were all using fountain pens or rollerball pens, so we effectively just had a big round hole in the top right corner of our desks.
who gets to decide what is respectful? You? Respect the web, lets start there.
Remember the transition of text to Unicode? 32 to 64-bit? Intel to ARM? Y2K?

No-GIL is a much smaller shift. It can follow the same transition path without radically breaking things. And if some things do break, there would be a well-defined way to handle those cases.

We all somehow survived those. Glad to see forward motion on this. It will open up a lot more terrain that has been marked off as untenable.

One of the things about early Swift that they got right was building breaking changes into the promise. Everyone knew where they stood and adjusted just fine. Sometimes I wish Python would take the same path.
It is the layout. They had a nice bypass set up, but the first day the train derailed and it has just recently re-opened.

Sharing track with freight is a PITA: the freight trains don't care about going fast (so no really straight tracks) and they often have priority especially if the cascade is running off schedule, causing even more delays.

Not sure where they are going to build new straight-enough HSR track unless they employ lots of viaducts like china does.
You can down vote this til the cows come home but it’s historically what happened.

This “that’s not how it went” stuff going down is quite just blatant historical revisionism.

Maybe it’s a good idea? Maybe it’s not?

…but anyone down voting “this reminds me of the Python 2/3” fiasco has no idea what they’re talking about.
Having spent a decade inside, I agree with your overall sentiment. There are some people who are completely unable to control their criminal behavior and probably just aren't safe to be released, but they could certainly be held in more humane conditions as their issues are probably due to the DNA lottery rather than anything they brought on themselves.

But, the vast majority of those I met would be totally capable of living productive (tax-paying) lives if they had the necessary support to get their lives rebooted, employment and shelter found, etc.
Engineers? Probably only a few anoraks cared. But people were definitely paying attention to who produced the album. After all, that is why Nirvana wanted to work with Steve Albini, who had produced the Pixies. It is why music fora often feature debates on whether a particular producer improved a particular album, or ruined it.

Similarly, if an album had string arrangements, or extra horns or percussion, and the performers were listed in the album art, ordinary listeners did follow up on that and seek out those performers’ own recordings.
99% of people don't even know what's an API key.
Disappointed black guy meme upon realizing a lot of “data science” is just calling some scikit learn module lol
I didn't see any mention of individual student records anywhere; seems like a red herring.

It's very possible to aggregate and anonymize (remove PII); aggregate the records by zipcode, anonymized school ID, school district, grade-level of student, age of student, educational attainment, etc.

You agree that's possible, FOIA-compliant and has been done already for decades? Like how Census data is made public (the Census also uses fuzzing to prevent reverse-engineering to individuals, esp. in tracts with small populations).

> Any Joe Taxpayer doesn’t have a right to walk in and demand any data they want from a government department.

Red herring: the CDE is not trying in good faith to define what level of aggregated data would be sufficiently anonymous; they're blanket-opposing legitimate public access to this data (even highly aggregated) via the researchers being allowed to testify in court.

> How about data pertaining to your kids?

Absolutely can and should be disclosed, in aggregate. Otherwise you have a public entity spending $128.5 billion taxpayer money that is not performing so well, violating constitutional disclosure requirements, gotten worse since 2020, lost students to homeschooling [0] and move-aways.
In any case, this isn't fodder for an opinion poll, it's what the Constitution says.

Seconded, such a great post, thanks for taking the time to research and write it!
The line is owned by BNSF and has quite a lot of BNSF and Union Pacific trains running on it daily, in addition to the Cascades services. No amount of improving the tracks will fix congestion, so moving to a separate line entirely for passenger service makes a ton of sense.

Vancouver BC to maybe Salem is pretty densely populated. They won't get much density past that to get to SF.
Poland broke Enigma? Is the whole Bletchley park history just some fairytale?

CERN is not a country. Neither is Tim Berners Lee for that matter.
For cultural context to this from the American side, as I recall, in the US military, if an American flag has become desecrated by allowing it to touch the ground, tradition was for it to be disposed of by burning. If this rule is still followed, I would expect burning would seem the obvious way to respectfully dispose of any desecrated sacred item.
But critically not exit nodes. Exit nodes should still only be run by people who know they are running exit nodes.
There are now only 3 decent sized concentrations of people in that corridor, but maybe building something like this would allow a whole new 1MM person metro to develop, e.g. around Olympia or in the Skagit Valley

So besides there appearing to be higher prevalence in women than men, and possibly identifying a protective factor, there isn't much to see here. I expect antivax twitter will quote the headline as proof of conspiracy and continue on their merry path of righteous ignorance regardless.
I agree, but the fact is probably that they don't want you to know. They want you to have to show up and end up buying stuff. They also continually rearrange their stores for no apparent reason, so you're wandering around looking for the same item you bought two weeks ago.

I like Costco, but have considered abandoning it because I'm sick of staple items I've bought for years there just... disappearing. You drive over there and start scouring the aisles for, say, brown rice. NOPE. They just don't have it anymore. And in many cases it's KIRKLAND products.

I understand that a supply of something might temporarily dry up, but then I wish Costco would replace it with the same thing from another supplier at full price if need be. Then at least I can get my shopping done without driving all over town. If I'm going to have to do that, screw it; I'll just go to the regular grocery store.

Downtown Portland definitely counts. I would include Vancouver BC. Traffic is really draining up there, more so than downtown Seattle.
Personally I don’t think nihilism is a great compass. You’re right - what’s the point? But do we need a higher good to beat on? Why not just enjoy the essence of our personal temporal existences and make whatever meaning makes sense to us as individuals?

And I don’t think doom is the right word. I mean yeah, Homosapien as we know it being wiped out but in a way similar to Neanderthal.

But it’s just one theory on it all. :)
Use a bike instead of a car and you'll be there. (Ideally you can even have your bike be foldable for maximum convenience)
Construction is expensive, and purchasing right of way in populated areas is ridiculously expensive. Short tracks are more expensive because you want to do inconvenient things in order to keep them short (like tunneling and building bridges) instead of taking the path of least resistance. You need all of these things for a good high speel rail, but you need a lot of it to even improve the existing rail. There's some compromises you could make to improve the existing system, but there's not much desire for it I think since it'd still largely be a many billion dollar long term project. I think the opinion is that it's not worth spending all that unless it's transformative (i.e., the marginal benefit of a 2 hour vs 3 and a half hour train ride is small compared to the benefit of a 3 and a half hr ride to a 1 hour ride since at that point you have realistic commutes and such).
> urbanist aesthetics demanding everyone live a very particular lifestyle, which includes a lot more than just urban living hamstringing projects.

You’re literally just describing how most of the population lives and has lived for the past 1000 years. Your “urbanist aesthetics” predate the invention of cars.
Chromium Community Leader Calls WEI Critics “Bullies and Criminals”
Where will you get no-GIL libraries, especially in the early days? Just yell at the maintainers of core libs like flask and requests until they use their volunteer and spare time to implement incredibly complex and tricky locking semantics all over their codebases, AND test it all with both GIL and non-GIL interpretors at scale to suss out race conditions? That just happens for free and overnight because a lot of people are plus one mashing on GitHub issues I guess?

Paris felt extremely different than New York to me.

Firstly, much cleaner. Just in terms of trash/litter on your average street.

Secondly, the integration of metro into the regional train network. Amtrak tries, but it's a sad cousin to European rail systems.

Thirdly, weekend markets and general ingredient quality. Paris feels like it cares about ingredients a lot more than the US. Even canned meals from Franprix were pretty good. And don't get me started on the ridiculousness that is Picard.

Small French towns will always have a dear place in my heart though. If I had my choice, I'd still pick them every time over Paris.
From experience, the type of people who judge you on that aren't the ones worth dealing with.
In the article they point out that for proper HSR you need segrated straight tracks.

Sure, for faster ordinary trains 100mph - 125 you need to improve tracks too, but a lot of that is also improving junctions implementing flyovers and extra track so that trains aren't delayed or stopped.
