Yes, a lot of obvious tells.

The photons don't slow down. It's the phase velocity that slows down because the electrons in the medium rearrange themselves in the presence of electromagnetic radiation, causing interference reducing the phase velocity of a wave. This is why the dielectric constant is related to the polarizability of a medium.

It's more about how fast communication can happen within the medium. The Cerenkov radiation happens because electrons can't "find out" about the charged particle coming through, creating a shock, similar to a sonic blast or the wake of a boat.

Hopefully I got this more or less right... I build detectors to look for Askarayan emission (a related phenomenon in the radio) but I'm definitely not a theorist :).

Just wait until wireless networks on the moon ruin that too.

These are either incidental or unauthorized transmissions. Not the Ku band downlink to terminals.

They are leakage from switching mode power supplies.

I bet the 137 isn't though since that's a common satellite downlink band. Swarm who they acquired used that

But passkeys are not supported natively (i.e. without a USB key or other shenanigans) by Firefox on Linux, as there is no place to store them. I do have a USB key, but it's annoying enough that I don't like passkeys if I can avoid them (instead using long randomly-generated passwords by Firefox's builtin-in password manager).

Maybe Lennart needs to write systemd-passkeyd .

I admit this is a gap, but this use case is a rounding error at the scale of users and daily logins. If someone wants to fix this, drop a link to sponsor the time and tokens needed to enable native support. Does a Yubikey or secure authenticator work for your use cases currently?

Yes, a yubikey works for when I really need it, but it's enough friction to take out out and plug in that it's just annoying enough.

I'll talk to some industry folks and see what we can do.

   It was considered at the least a sin to reveal that sqrt(2) was irrational to those outside Pythagoras circle

perhaps a 2 sin 45?

Don't they ship a propetietary clang variant with weirdass version numbers? That was true at least at some point. Fortunately most Mac users on my experiments have given up attempting to compile any code in their Macs after SIP etc made it too annoying so rarely have to support them anymore.

I guess it could in principle be profitable for the website, not the client?

unfortunately at that point it would be indistinguishable from running cryptojacking on your website

No. The client is doing the work.

The client is doing the work in both cases

Yup was thinking the same: make honest people pay $0.00001 when they visit the site (in electricity/compute), have the challenge made so that only the website wins a tiny something. Bleed the bots dry.

> This makes Anubis challenges use a memory-hard proof of work function (argon2id) instead of just a CPU hard one. It also means that the "hey Claude vibeslop me a CUDA Anubis solver" route is on its way to being fundamentally dead.

Nice.

For instructions you really care about, yes of course you review the assembly output! Usually when you're doing SIMD or want to check atomics are doing what you expect.

You can do that with LLMs for the parts you really care about too. The LLMs aren't regenerating the codebase from scratch every time, so the results stick around.

Only if it's not too byzantize to understand what part you should look at

The AI can tell you where to look. It's really good at this. It's actually a lot better at analyzing code than it is at writing it.

that's FPGA firmware isn't it?
