In my lunch break i had the chance to try out ArielOS, which is a collection/framework to build and deploy firmware for microcontrollers in Rust.
It abstracts some of the boring repetitive work away from the user, for example board switches are really easy, so you can write your code board-agnostic (to a certain extent).
Really cool.
dorotaCMy #FOSDEM discovery: #ArielOS .
#Rust, both #async and preemptive scheduling, microcontroller-friendly. Based on #embassyrs .
Sounds promising, gonna have to check it out once I'm back home.
chrysn@Teufelchen (One of) Those user(s) was me -- I use it to control #DectNRplus devices running #ArielOS , and "Just run `cargo install Jelly`" is the simplicity of getting-started I want to have there.

We're gathering momentum for slipmux, a transport of #CoAP over serial ports. That specification allows #embedded developers on simple boards that just have a UART to use the same tools with it as for talking to devices across the Internet. This includes security: I guess I just sent the first encrypted request over slipmux ever, and its security setup was unmodified from #ArielOS's CoAP example.
Implementation is available in #RiotOS (#C), and WIP for Ariel (#RustLang) and #aiocoap (#Python).

Since we started using `cargo vet` in #ArielOS, I'm happy to see that some of the crates that we previously on our list of "yes we should review them but don't have the resources now" are vanishing from there because other parties we trust have actually reviewed them.
The ecosystem is growing! ❤️
The #IETF122 hackathon starts in a few hours. I will be joining remotely, work on #EDHOC on @ariel (let's see if its out-of-the-box support also interoperates out-of-the-box), and play with #embeddfriendly URIs expressed in #CBOR.
