I came here to ask this, as well! Where does that tension come from and the relief one feels after cracking? People keep saying it's built-up gas but that doesn't really explain why we feel so much relief after cracking. (Not just when cracking our knuckles but also, or especially after, cracking our back, neck, etc.)

The article provides some hints at least but I wish there'd be more research on this topic:

> For some people, cracking can provide a sense of relief and a temporary increase in joint mobility, because it stretches the joint, taking it through a wider range of motion. One theory even suggests that cracking stimulates nerve endings around the joint, relaxing surrounding muscles while reducing pain and releasing endorphins – but this hasn't been proven.

> They seem optimally designed to ensure that you'll have glare on your screen no matter how you position it in any kind of well lit environment.

At work we have dozens of curved monitors by Dell. Not once have I seen glare on them.

> They don't offer the window management affordances that having separate screens do, or they have some weird software kludges to do similar.

But once you have figured out the window management stuff, they do offer better ergonomics! (And you don't have to daisy-chain monitors, etc.)

Yesterday[0] I learned that supernovae can be driven by Kevin-Helmholtz instabilities, so when I saw the title I was already getting worried. :)

> That voting has obviously been done by people who have never read the original texts of the people for whom they have voted.

That's a rather wild claim, given that the article says

> The survey was conducted among 100 of today's leading physicists.

> The only downside is that because of Jujutsu snapshots it can't be used inside sandbox (since all jj commands are mutating)

I guess it depends? You could certainly start with another repo clone that's separate from the one you work on yourself?

> He got personal visits from both Ballmer and Gates that pressured him to stay with Microsoft[2] but did not balk.

So he did not refuse to comply, i.e. complied? I think the parent is right: Grandparent probably meant "he did not budge".

What cards & banks does it work with these days? Last time I checked, it wasn't really a serious alternative.

> better version of Jira

Nah, man. I would be a LOT more productive if I didn't have to wait all day for Jira tickets to load every single time, or that dropdown to load, or that popover to show, …

Another Firefox for Android user here. I get popups nudging me to install their app all the time.

From the The Guardian article:

> As well as living matter, inorganic substances also crash to earth, including seeds, stones and sand. However, these pale in comparison to the mighty ice blocks. January 2000 saw several chunks weighing up to four kilograms each fall on Spain, but they're dwarfed by the 200kg titans that struck Brazil in 1995.

Wat. Does anyone have a reference for the Brazil one? Wikipedia (https://en.wikipedia.org/wiki/Megacryometeor ) mentions nothing. Megacryometeors: Distribution on Earth and Current Research (2006)[0] says:

> In Campinas and Itapira, Brazil, two huge megacryometeors of 50 and 200 kg fell in 1997; the atmosphericisotopic signature of both specimens wasunequivocally confirmed (8). Finally, on 21 July 2004, a huge mass of ice weighingapproximately 400 kg fell very close to a 15-year-old girl in Toledo, Spain.

400kg! Unfortunately, no reference is given for this one and for the one in Brazil they refer to https://cepagri.unicamp.br/gelo/gelo.html, which – like many other of their references – produces a 404 nowadays. And, of course, the page hasn't gotten preserved by the Internet Archive, either. :(

Nah. I just put a regular `main.py` with some

  if __name__ == "__main__":

in my src/ folder. Done.

Seconding this request!

Until a few minutes ago there was a countdown page. (The weights haven't been released yet.) The countdown should be over in 19min, not sure why we're suddenly getting a 404.

Yes, see https://www.theguardian.com/us-news/2026/jul/23/cop-city-pro... . The OP is a response to this, as has been pointed out several times here in this discussion.

I would love a blog post on this, in case you ever considered writing one!

IIRC there was a blog post here on HN recently explaining in detail why Anubis doesn't keep out AI bots.

> (Related lesson from my 10 years employed by GitHub: they almost never do the git gc you’d expect to remove commits so once you push a commit: it’s likely there forever and identifiable by that same hash from anywhere in the fork network. This can be bad/scary so be aware).

Oh wow. Is there a way to trigger GC manually?

> those long-standing rules may no longer make sense, in a world where 1. it no longer takes even a weekend to build the niche, perfectly custom tool and 2. the maintenance / feature requests side is also just a prompt away.

…as are your own, perfectly custom security vulnerabilities and their successful exploitations.

> But very sad he has no (real) tips on dealing with hand fatigue

I also spent a good amount of time in academia (math & physics), wrote everything by hand (dozens of pages per day), and I, too, suffered from serious hand fatigue & RSI for years, even when using a fountain pen. My recommendations:

- Use as light and as thick a fountain pen as possible. Also, very thin & hard pen tips may be nice but in my experience they make it harder to write.

- Work on your posture (if you don't do that already). Work out your neck and your back in particular to compensate for sitting all day every day. A stiff neck (even if you don't feel that it is stiff) can seriously impact the nerves in your arms & hands and, thus, muscle tension & recovery.

Incidentally, Claude Code has been very buggy for me lately (much more so than before). Lots of TUI rendering issues causing, e.g., the conversation history to be garbled etc.

Same in Firefox for Android!

Great article. I would love to see a similar article about how POS credit card / debit card payments work in the US/Europe, depending on whether you use the card's magnet stripe, chip or your phone (Apple Pau/Google Pay/…) to pay.

As was mentioned countless times here on HN, the fork didn't get merged not because of any no-AI policy but because the Zig maintainers considered it to be of poor quality and were already working on more comprehensive improvements to the compiler which would bring the same (and more) benefits, but without the downsides and quality issues of the fork.

It's not even a fix for the harness, as the calling user account's permissions are usually still enough to exfiltrate or manipulate data. See also https://simonwillison.net/2025/Jun/16/the-lethal-trifecta/

As the sibling already said, this doesn't work/help in most cases. See https://simonwillison.net/2025/Jun/16/the-lethal-trifecta/ for a different explanation of the issue.

Interesting, I didn't realize Maps.me used to be open-source! I suppose this is the code (from five years ago): https://github.com/mapsme/omim

To everyone saying that this has always been a problem: The issue is the scale of the problem. Deleting the occasional spam email by hand is not a big deal but once you're getting flooded with spam emails, you better have a good spam filter in place.

In the same vein, the early hiring funnel discussed in TFA did work in many if not most cases or otherwise people wouldn't have used it. This no longer seems to be the case.
