Heavy lift drones are pretty common, a 150kg or more payload is enough for a soldier with his individual equipment. The are pretty short ranged but they only need to reach to a few kms into the grey zone and back.

See e.g. the KF 150 multi copter. And it's sub $50k

Yeah, more weigh less range. 100 KG human with body armour/rifle, and a small combat load would be around that 150KG limit.

Problem is staging is hard, because you take fire trying to set them up, so you need to be further away, which brings up the weight/range issues.

And that's why the war is fought with one way attack drones, to maximize range and payload.

This looks fun.

Unfortunately the price when including shipping and taxes is fro me 455 EUR, which is twice my budged :(

Thieves and intelligence agencies can be one and the same, see North Korea... Crypto is especially useful for heavily sanctioned countries.

Do you? Someone actually sell backdoored crypto wallet insurance?

Insurance for cyber incidents usually only cover you if you took reasonable measures. Like not exposing your internal systems to the Internet.

If someone walks in and unplugs your refrigerator and causes you to lose all the stock in it, your insurance is going to cover you. You don’t need to show you locked the power sockets.

Many business insurance policies come with requirements for physical security, if you've skimped on them, you're not getting paid out.

It depends if they entered by forcing through some security facilities or the door was full open with a white on red panel "the plug is over here" and a big arrow pointing to it.

Most store doors are open much of the day

Also talking about quantum computers breaking SHA-256 means he knows a lot more than the rest of us or not nearly enough to pipe up about the subject.

"The ARM-based CPU manufacturers make this worse by posting almost no low-level documentation for their CPUs."

Are those not based on standard ARM cores or ARM documentation on its cores not deep enough for your purpose?

Both. The specific documentation I'm referring to is their optimization guides, such as the Cortex-A72 optimization guide:

https://support.arm.com/documentation/uan0016/a/

This has detailed information on latencies and throughput, which are important when optimizing SIMD code. But ARM doesn't publish optimization guides for all their cores.

On top of that, the cores are often modified in significant ways. Snapdragon CPUs, for instance, have used modified Cortex cores in the past and can have performance differences from the original core.

To be fair, Intel's been slacking a lot on this too, not even bothering to update their own optimization guide for their latest cores. But that's made up for the community mining this information in great detail on sites like uops.info, and also being a lot less x86 cores to deal with. On the ARM side, there's practically not much analogous other than the Apple M1 microarchitecture analysis.

They are in valleys and I think the risk assessment was heavily influenced by https://en.wikipedia.org/wiki/Cumbre_Vieja_tsunami_hazard which has been toned down quite a bit since... But IRSN (now ASNR) studies all kind of risks seriously...

Title edited for length from "Coding Agents Build Chess Engines From Scratch in Rust, C++, COBOL, Rocq, LaTeX, Brainfuck, and More"

He also has dedicated entries on two very special case, the engine running within pdflatex https://blog.mathieuacher.com/TeXCCChessEngine/ and the one in Brainfuck https://blog.mathieuacher.com/BFChessChessEngineBrainfuck/ which are seemingly the first of their kind.

The discussion on the cost of the attack needs an addendum. The lattice sieving part would be free for an an attacker with a big enough botnet or enough cloud computing stolen credentials.

Maybe it could even be practical to run it on browser in parallel to video streaming on a free video site...
