It's a nice coincidence for that the most appropriate MCUs for my project and the ones with the best Rust support seem to be the same.

The lead developer of ESP32 Rust support started it on his own as soon as Espressif released their LLVM fork in 2019, then 2 years later, Espressif hired him. https://mabez.dev/blog/posts/esp-rust-espressif/

I love that not only is Espressif officially maintaining Rust support for their MCUs, but they're writing the tooling for it in Rust and dogfooding the Rust HAL in the tooling. The espflasher tool runs this little stub written in Rust with esp-hal on the MCU that interfaces with C code in the MCU's ROM. https://github.com/esp-rs/esp-flasher-stub/

Espressif is also investing heavily in upstreaming support for their MCUs into LLVM & Rust. This has required jumping through bullshit hoops to write clean room documentation for the Xtensa ISA before upstream LLVM maintainers could even review code. 🙃 https://github.com/llvm/llvm-project/pull/118008#issuecomment-2531343817 But they're getting it done, and Xtensa support is making its way into upstream LLVM. The newer RISC-V ESP32 models don't need that, but Espressif commits to supporting MCUs for 12 years so Xtensa will be around a while.

@skinnylatte It's been a while since I've cooked with tea. Thanks for the reminder that is a thing that can be done.

@alcinnz The best way to handle authentication I've found is using the Kanidm identity provider (https://kanidm.com), which encourages passwordless authentication and has no requirement for passwords, TOTP, nor email. It supports passwords and TOTP as fallback authentication methods, but those can be disabled per user group by the system administrator. By default, it requires either Webauthn or a combination of password + TOTP.

Welcome to the fascist future, where the rich gentrify city blocks then turn them into gated communities with private rent-a-cops

A library by the same lead developer has a Blockchain [Non]support Policy in the README.md:

I like this too.

Maybe a hot take, but I feel this is way more important than a Code of Conduct.

More software projects should have a Developer Ethics document:

10 meters of APA 102 LED strips with 144 LEDs/m ordered. Going to make some pretty rainbows and learn embedded development in the process.

Aliexpress is a terrible website. Completely different prices after logging in, and every listing that shows up in search results can only order one of each item??? And that's after waiting a confusingly long amount of time to get the confirmation email to log in.

Nevertheless it's the cheapest source of LED strips that I found.

25 10440 batteries ordered... hopefully I don't cause any of them to explode or burn 😬 Ordered them from https://liionwholesale.com/ which is a good place to buy batteries according to flashlight nerds.
