> Wow, for an HN comments section, this feels weird. How can people be so annoyed of a plastic straw / bag ban? It is a minor inconvenience.

HN hates minor inconveniences when we feel they're unjustified. Look at how many complaints we make about e.g. password rotation policies. No, it's not hard to rotate your password, but it's infuriating because it's a stupid counterproductive rule.
By "production grade software" do you mean major sites like Instagram or Reddit?
Arguably better than just dying. We have to try something.
They got a billion dollars for a year old company i don’t think that can be characterized as selling because they didn’t have a funding model.

Fine, Facebook , TikTok , Reddit and myriad others have found how to moderate and monetize user generated content if you need better examples
I think selling fully reusable cloth bags would be the right thing to do, but otherwise I agree that stores shouldn't offer single-use plastic bags any more.
My 12 year old self would agree with you. But I was still opening and closing my friends CD ROM drives at 12 also exposing their home computers to anyone who knew what port to scan. Yeah it was fun but I didn’t fully grasp the consequences at the time. The consequences of piracy are severe to the pirate and to the artist. The true spirit of a hacker is indeed an artist … Someone who questions societal norms in expression of their skills that paints their insight or dissonance for the rest of us to enjoy. In this case your moral imperative is cognitive dissonance. If you find a way to pirate and directly support the artist (cutting out the corporations you hate) that would be more of a moral imperative but also ignoring the importance of the suits that support the artist financially, legally, and pragmatically.

Seems fine to me. Grades have always been totally arbitrarily. Just look at test scores instead

Henry says. "What we're saying is, 'You were in the car. What's going on with you? Why is this fun?'"

...Or, instead of inconveniencing honest, law-abiding citizens, we could ensure that the small percentage of criminals is unable to re-offend? Enforcing the law worked in El Salvador, it can work here too
Competition clearly isn't exerting those pressures on the market, and there are good reasons to believe it can't, which I've already outlined: The failures of an insurance company are too infrequent, ruinous, and obfuscated for customers to make choices at enough of a scale to impose this discipline in practice
Just as every major company now sends out fake phishing emails, we'll need to normalise sending out fake emergency emails from your boss saying that you need to transfer money somewhere.

Nope, all he proved is that there is no automatic and purely formal way of arriving at truth. Doesn't mean that for any particular truth we cannot stumble upon a way to understand it anyway.

For example, we cannot write a program (= automatic and purely formal way) to determine in general if an input program halts. But for a particular input program, we might be able to understand whether it halts anyway. There is just no a-priori guarantee that we will.
What do people expect to happen when they mob a celebrity like that? Like what's the point? They're not going to perform a show for you while waiting in an airport lounge. I can understand the reverent fan who attends every concert and goes out of their way to do so, and I can understand (in a way) the psychopath who wants to take home their body parts, but I cannot understand the fan that wants to ... fill in blank here ... by mobbing and getting in the face of their idol.

Bambulab A1 Recall Update
I think that if you don't want to wash your reusable bags, then you are very much free to refrain.

For the rest of us, there are reasons to consider doing so, as advised by the the New York State Department of Health above.
Oh yeah fuck the DRM... Amazon was even worse with that (got like 360-480p on my laptop wtf), netflix got to 720p. Even then, the bitrate felt so low sadly
> The problem is that there's about equal amounts of malice as stupidity in the world

Also, they are often connected. People who don't know something often refuse to learn it or even to hear about it. Not knowing something is stupidity, but refusing to learn is a conscious decision to be stupid in harmful ways, and that is a form of malice.

I was paying for Netflix 10 years ago in France for a short while, wanted some English subtitles for my wife for some US shows but there were only subtitles in French so had to download the same show elsewhere if you know what I'm saying... with English subtitles readily available. I also remember watching some shows like the first two seasons but then only to find out the third season was licensed by another streaming service lol. Such a UX disaster for paying customers.
I thought it was going to be first something like "isn't recursion cool" (like, look at these fractals in sea shells!!!!), until GEB actually tried to explain, in detail, how Godel's proof works. tbh, that's kind of what makes the book cool, it just assumes anybody with a passing interest in compsci would also love to dive deep into fundamental theorems of mathematics. Those sort of bold assumptions, and the author just doubling down on them (e.g. you're going love these dialogues!). Crazy that it won a Pulitzer too, a real bestseller.

No, principally because although he writes:

He doesn't seem to have much more to say about the latter than that.

'My reply', bluntly, is something like 'maybe it has shortcomings, you haven't addressed them; its most fundamental key advantage is not addressed at all, about it or any other language, and is not a feature of your new one'.
1D Room Temperature Superconductivity in LK99, Pcposos and Wrinkled Graphite
How could they commercialize it in ways they already haven't? There already exist good, free torrenting clients, and piracy is illegal. The most they could do is set up a subscription service for exclusive torrents which always have seeders, but that's already being done AFAIK, and it's illegal, so they can't really run ads on TV about it.
Also having to look for the hardware that has the right DRM support to be deserving of 1080p streaming rather than 480p.
It doesn't sound like you necessarily disagree. Maybe we use different meanings of "worth the effort"?

I meant it in terms of money that a company can save or make from deciding to expend that effort. You also have an additional cost in terms of "risk" that the effort does not yield desired results. So "they're delusional" would only be true if the people deciding this seriously overestimate the effort to verify something or seriously underestimate the benefits. Do you think that's true in general? Or even in the examples you cite?

It seems like Apple and Google know what WUFFS is and what it can and cannot do, so they understand the effort. The maximum conceivable benefits in the cases you mention would be "no security vulnerabilities in said code". I'm not sure that is seen as a huge benefit by those in charge. Even rewriting that stuff in Rust (or even Swift) would significantly reduce the probability of weaknesses being exploited. Nobody seems to think that's worth the effort.

The "marketing pitch" of WUFFS is: "as safe as Go or Rust, roughly speaking, but as fast as C, and that can be used anywhere C libraries are used". So, presumably, Rust and Go are equally and sufficiently safe, "roughly speaking"? And Rust is neither fast enough nor easy enough to integrate with C code (despite being good enough for drives in the Linux kernel)? This sales pitch makes it clear that the people behind WUFFS are keenly aware that "safety" alone doesn't sell.

This problem is generally more endemic of software security in general. The cost of security issues is usually not borne by the people who decide how much to invest into security. Also, security does not contribute to profits, it is only a cost center. By contrast, when you have really important code and you bear the cost of mistakes and outages directly, formal methods are being used where it can be done straightforwardly. AWS and some cryptocurrencies (for whom security and correctness is an above-average part of their sales pitch) have prominent uses.
what a sucker lol
A buddy of mine and I wanted to experiment with such a thing back in ~'85. I started by looking at the "elvis" editor code, trying to wrap my head around it, but I didn't really have a clear picture in my head about what a "modal AST editor" would do, just some vague ideas of an editor that operated on parsed syntax (AST wasn't on the horizon for us at that point). I was in HS at the time, and my buddy was working on a masters thesis, I think he was too busy and it was way too big a project for me to handle at that point.

One interesting thing about GPT&cetera is that in order to "cheat" by using it, you need to clearly describe the problem you are trying to solve. If we can get more people to design before coding begins, I think we're going to have a win in any case.
That’s a good point - I wonder why the two industries evolved differently.

I would think exclusive music would add much greater product stickiness than exclusive video content.

So this category of weapon is called a Close In Weapon System.

Moskva had 6 of these, the main russian CIWS: https://en.wikipedia.org/wiki/AK-630 It also had 40 short range surface to air missiles.

No one knows the exact details of the strike, but it's been suggested that Ukraine used a drone as a diversion. Another speculation is that in photos of the ship after the attack, the main search radar is in the downward, stowed position. This may suggest it wasn't on at the time of the strike, or it may have been moved as part of damage control.

All that said, incompetence has been a consistent theme with the Russian military in this war, and in particular with their black sea fleet.

Ukraine has had repeated success attacking with small unmanned surface craft, basically Ski-Doo style boats they've modified for remote piloting using a thermal camera and Viasat, and with a bunch of explosives. There's video footage from these attacks on twitter and such, and while it's very unclear, in some of them it appears there's no watch standing on the ship being attacked, or they're shooting at it using small arms rather than the CIWS.

None of this is definitive, but it is all consistent with poor training, apathy, and incompetence on the part of the crews.

I timed the Buz Hash (https://en.wikipedia.org/wiki/Rolling_hash#Cyclic_polynomial) at about 1.38 cycles/byte on Skylake generation - but only to "hash in" (i.e. no hash-out). At 6Ghz that should translate to >4.3 GB/s/core.

There is a 25 lines of Nim code implementation over at
https://github.com/c-blake/ndup/blob/15ec9b0e67750ae1b70761e... but the charm of the technique / idea of Bob Uzgalis' ("buz") is its extreme simplicity. (That Nim version also uses the ease of computing very statistically independent hashes in parallel for this near duplicate detection idea.) I'm sure you could write your own pronto.

I haven't tried it, but if your CPU L1/L2 cache is big enough, you might be able to get a boost from doing 2-bytes at a time instead of 1 byte at a time. (65536 entries * hash-size per entry =~ maybe as little as 256..512 KiB. Big "IF", though.. since while you can do half as many loops, you will also be waiting a lot more on cache.

(EDIT: and dunno - it may not be as collision resistant as your end-use case needs. Perhaps that's why you qualified that sub-kind of rolling hash being of interest.)
It seems to be quite a bit harder for dubbed stuff in non-english languages though

Not the best recall update that I've read, but at least it seems like they are providing a decent enough set of options for customers.
That recursive macro approach allows FOR_EACH to accept up to 4^N arguments (where N is the number of lines in the definition)… at the cost of making every use of FOR_EACH perform O(4^N) expansions, a fixed number regardless of the actual number of arguments. For high N that can slow down preprocessing.

In the past I've used a style like

#define FOR_EACH(macro, ...) __VA_OPT__(FOR_EACH1(macro, __VA_ARGS__))
#define FOR_EACH1(macro, arg, ...) macro(arg) __VA_OPT__(FOR_EACH2(macro, __VA_ARGS__))
#define FOR_EACH2(macro, arg, ...) macro(arg) __VA_OPT__(FOR_EACH3(macro, __VA_ARGS__))
#define FOR_EACH3(macro, arg, ...) macro(arg) __VA_OPT__(FOR_EACH4(macro, __VA_ARGS__))
[etc...]

which doesn't provide exponential growth in the maximum argument count, but does decouple the maximum count from the number of expansions. Even if you continue the pattern up to FOR_EACH100, calling FOR_EACH with 3 arguments will still only do 3+1 expansions.

The author chose N=4 for the recursive macro approach, supporting up to 256 arguments, at the cost of performing 342 expansions for each use. That sounds reasonable; preprocessing is much faster than other compiler passes and you probably won't notice the cost at all. So it's probably better than my approach.

On the other hand, if I bump the recursive approach up to N=10, supporting up to 1048576 arguments at the cost of performing around that many expansions per use, then performance becomes obviously unacceptable (when running `clang -E`, you can watch the tokens being emitted one by one). So you do have to set a limit somewhere.

I wonder if there is some way to get the best of both worlds – exponential maximum number of arguments per line of code, but still only a linear number of expansions per actual argument.

While we don't know much about the content of the jets. We know that there are ordinary matter in there. Specifically we observed nickel and iron [1].

The positive charge in these jets was initially unclear, with possibilities being either positrons (the antimatter 'opposite' of electrons) or positively charged atoms. However, the discovery of nickel and iron indicates that the positive charge is provided by positively charged atoms, not positrons

I have about $120 in streaming subscriptions (wife, daughter). Lat week I wanted to watch Korean movie “Sleep”, which I then found and rented from both Google and Apple. Turns out that neither had subtitles in English. So I refunded both and comfortably watched it in an “alternative” streaming site. I really try to pay for content but this fragmentation is destroying the business.

You put a platform in geosynchronous orbit and then lower a cable while raising a counterweight. The orbit of the entire structure is then balanced. The tricky part is lowering the bottom part through the atmosphere and securing the base.
I have, unfortunately, seen this behavior and outcome with many types of government contracts, not just cost-plus. One of the worst had the contractor so deeply embedded in a program office the IG got involved as they were receiving incentive payments despite failing to meet contract requirements (despite several government people losing their positions, the contract was not lost even though fraud had almost certainly occurred).

There are certainly some contractors who aren't as deep into the grifting, and a small handful who really are sincere, earnest, and successful, but they're a rare breed. The big contractors (Raytheon, LM, NG, Boeing) keep eating up the little ones, and the outcome is about what you'd expect from these conglomerates.
If you have the time and the inclination, one of the best things you can do is go talk to Cliff Stoll at his home in Berkely from which he operates Acme Klein Bottle. He not only sold me the bottle, but gave me a tour of his "warehouse" - Actually the foundation of his house, which he drives a custom RC forklift around to store his bottles.

This is the same Cliff Stoll of The Cuckoo's Egg: https://en.wikipedia.org/wiki/The_Cuckoo%27s_Egg_(book) - Which inspired me as a child to pursue my calling of being a systems administrator (Or Site Reliability engineer, in a slight evolution that would look more akin to what he was doing than what the Sysadmin title has come to mean)

His Klein bottle site has of course been discussed on HN before:

Crocodile tears, piracy beats streaming and will continue to do so as long as availability is a problem.

My example; a certain popcorn-related torrent site provides an archive of 315,669 movies.

Total torrents: 916,518

Webrips, full Blu-ray rips, remuxes, 2160p, 1080p, 720p, 480p; h.265/h.264, x.265/x.264, you also have DVDs and even VHS.

Some movies also offer 3D in various formats, some are director's cut, some are theatrical, some are uncut. I can go on, but just one movie is offered in a myriad of formats and options.

Places like these are equivalent to the library of Alexandria. They must not fall because they hold valuable media that is not even available elsewhere.

I remember Stallman mentioning a universal fee for internet access and all media, wishful thinking but for a subset of internet users this has been a reality for at least a decade.

With self-hosting services, VPNs like WireGuard and nice apps like Infuse on the Apple TV that can connect to any server and play anything you throw at it there's no going back for me personally.

At this point I find it morally imperative to keep seeding in order to keep media alive that would otherwise be lost to time because no-one else cares.

The big companies are all about profits, it's up to the little man to save the ideals of the early internet.

Show HN: The Calibration game – get better at identifying hallucination in LLMs
Calibration game is a game to get better at identifying hallucination in LLMs.

Prompts and hallucination labels (using ChatGPT) are obtained from Alpaca and HaluEval. You can use your own dataset to calibrate users to the responses of a different LLM (https://github.com/Viktour19/calibrationgame).

ML engineers are starting to come around to the fact that hallucination in LLMs is really tough to mitigate. This is an active area of research and we may have LLMs with no hallucination in the future. At the moment, we need to design user experiences that align users with this behaviour. The hope with the Calibration game is that it equips engineers to calibrate users to the responses of LLMs used in their applications, e.g., as part of the onboarding process.

Would love to hear some feedback.
