Whoops... it was formed by agricultural run-in! Regardless, it's sort of a bad example of "humans are the virus" type thinking, since it both lived and died by agriculture. If you really dig into the story there is an interes

The Salton Sea is drying up due to _decreased_ agricultural water consumption in the area; it was formed by agricultural run-off, which is why it's so toxic, and now there's less runoff to fill it up.

Is there some rule that "bit banging" must refer to a primary CPU? I still think it's a good name for "implementing a protocol using instructions that run on a programmable core"; it distinguishes from using dedicat

Video codecs are a really good example of this too. We went from slow and unreliable video decoding in the CPU, to fully offboard / unsupervised decoders (remember the 90s MPEG-2/DVD players that would just blit onto a green part

That's the power of the Pico - the bit-banging happens in the PIOs, not the main cores. So idling takes no CPU (the idle symbols are pre-calculated and DMAed into the PIOs, which do the bit banging), and transmission only needs the CPU

I worked with a steel warehouse about 10 years ago who were using software written in a Data General Business BASIC offshoot dialect, which ran on a proprietary Windows runtime that was essentially emulating the original minicomputer which

I'm not even sure "fanatic" was the right word, as most of them actually had a pretty measured take on the state of Rust and were not the sort of aggressive evangelists that people sometimes associate with the language. They

FWIW, this was an intelligent rewrite, piece by piece. This is the only way I have ever seen "rewrite it in X" ever work. Fish also isn't a commercial product, so the calculus is a little different.

I think the author almost contradicts themselves; they reach the salient-but-obvious conclusion that rewriting a product is almost always a bad idea and that rewriting a product only to change programming language is _always_ a bad idea, th

This exact thing is irrelevant to Asahi; the reason they don't support suspend-to-disk is that their drivers don't support full reconfiguration. This is a difficult task, as is "true suspend," because Macs have tons and

The article's deep dive into the math does it a disservice IMO, by making this seem like an arcane and complex issue. This is an EC Cryptography 101 level mistake. Reading the actual CIRCL library source and README on GitHub: https:&#

There’s a strong air of grantware to it. The notion that it could be end-to-end auditable from the RTL up is interesting, though, and generally Wireguard performance will tank with a large routing table and small MTUs like you might suffer

This is conceptually interesting but seems quite a ways from a real end to end implementation - a bit of a smell of academic grantware that I hope can reach completion. Fully available source from RTL up (although the license seems propriet
