> surprising that more schools haven’t done this

We have a depressing state in America where you can predict the parents’ income based on whether their kids’ school bans smartphones.

First past the post, so no, not really.

Only thing? Just off the top of my head: That the LLM doesn't learn incrementally from previous encounters. That we appear to have run out of training data. That we seem to have hit a scaling wall (reflected in the performance of GPT5).

I predict we'll get a few research breakthroughs in the next few years that will make articles like this seem ridiculous.

The "chemists" (drug stores) in the US sell pantry essentials. I can't imagine buying a TV while waiting for your prescription!

Boots also used to sell home computers and games on cassette. Around 1983 it was an actual place to hang out to see the latest developments in home computing, and buy some toothpaste.
rwmj commented on Ask HN: Why does the US Visa application website do a port-scan of my network?    · Posted by u/mbix77

That would be quite clever for an incredibly horrible website. The other day my SO, who is a Turkish citizen, was filling up her visa application and after half an hour of meticulous form filling the system just kick her out. I think the session times out or something. If you haven't created an account or you haven't write down the current application ID everything is lost. In the process she was also directed to a non-.gov website for something during the process, I thought she was getting scammed but no.

It actually makes sense to have a paid service that makes this abomination less painful. Though they work with VFS Global for collecting the applications and relevant documents, the VFS Global itself is an abomination and doesn't help with the handling of the form filling anyway.

Recently EU streamlined the Schengen visa application process for Turkish citizens as those "visa agencies" that are the official agencies and the only way to apply for a visa for many countries don't actually help with anything and are scamming people by selling the "good hours" for the visa appointment on the black market. An agency was dropped for this and the scams by agencies were listed among the reasons to streamline the application process.

Both with US and EU people are losing scholarships etc. due to outrageous wait times that are sometimes are years ahead or there's an issue with the systems handling the applications.

I guess there must be an opportunity there to fix all this together with smaller stuff like handling transliteration and character encodings, I wonder if some of those scam site are not scams and actually help with it. An AI agent can be useful here.

You might be making the assumption that the US wants to make the process easier.

Lots of automation. Dicing is automatic, bonding, testing are automatic. The manual work is mostly just transporting materials.

The bonding machines are crazy. Definitely look it up on YouTube, the machine puts down bond wires super fast.

The other part of it is sheer scale. Once you start making thousands or millions of something, economies of scale drive the costs way down

And for reference there's a section in this BBC film about how it was done in the 1970s, by hand: https://www.bbc.co.uk/programmes/p01z4rrj

A bit surprising that the transaction ID is only 16 bits. Presumably the source port doesn't even need to be guessed if someone is on the path between dnsmasq and the upstream DNS server.

There are `asprintf` and `vasprintf` (takes a va_list argument). Those allocate a sufficiently sized buffer that can be released with `free`.

Yes, it's a GNU extension, but it's also supported by various BSDs [1][2][3], and yes, Musl has it too. It's present in pretty much any sane C library.

And combine it with __attribute__((cleanup)) to get the string automatically freed at the end of your function (if that's the right thing to do). Looks like cleanup with be standardized finally in the next C2x.

The most amazing thing about this (and another tiny RFID chip that was on HN recently) is not that you can print them on wafers, but that you can cut up the wafers and handle these tiny dies. Imagine you manufactured sugar, but had to manipulate each sugar grain separately.

Paywalled. Also where is the evidence that "most people come back to work after early retirement"? This is just workist propaganda.
