Ah yes, the radio test box that finds 99% of logic errors 😁 The kind of automated testing that can be done is an absolute treasure. Yankiness is included.

I'm excited to share what I've been working on with @erikjee.bsky.social: RustNL's #rustlang Maintainers Fund!
Many people and companies contributing to Rust, but there are fewer and fewer paid positions for general maintenance (reviews,cleanups,etc). We need to fix that.

We're excited to announce a new initiative to support the Rust Project, our Rust Maintainers Fund!
We are setting out to employ 6 full-time maintainers and 6 interns in 2026 to make sure #rustlang is well maintained and bugs and contributions get the attention they need.

We need your help to get Typst 0.14 over the finish line: The release candidate with accessible PDFs, character-level justification (not even in LaTeX!), and more landed today! Check your documents, packages and against "Typst 0.14.0 Testing" on the web or the new compiler.

Cool! Happy with the playground result.
Love how instant compilation is :D
I've probably committed crimes against the web with my HTML/CSS skills, but it works :)

The home page is super mega WIP, but that wait can until other more important stuff is done.

We're launching the embedded-cal project: Providing access to hardware accelerated and formally proven cryptographic algorithms on #embedded systems in #rustlang. For this, I'm teaming up with @inria Paris and @cryspen, supported by the #eu funded @NGIZero.
Right now we're going through […]

I feel like there would be a HUGE amount of ecosystem value for Rust and async/await, if there was funding and the right dev(s) available to focus on improving:
* Memory usage + copies of futures/async fns: particularly wrt overlapping data across yield
* Improving codegen size/perf
* opt-footguns

University took it's toll. Korken = bottle cap ... 😅
I can’t abide being called Jon, so I’d get my friends at school to call me JP instead. When I signed up to Force9 dial up in the mid 90s I needed a username for my email. I forget where I’d heard “the something-ster” as a format but that’s what I went with.

My first nick on IRC (Szasz) came from The Day the Sun Rose Twice by Ferenc Morton Szasz, later reversed to zsazs when someone else took that nick. zsazs makes a triangle on the keyboard when you type it. In the other corner of the keyboard, a similar triangle makes "polpo"

I remember reading long ago that COBS framing with CRCs as part of the data could greatly reduce the effectiveness of the CRC checksum and that care beds to be taken, but I'm unable to find where I read this. Does anyone know where this comes from, or if I'm mistaken?

MISRA have produced a document outlining how MISRA C rules apply to both safe and unsafe Rust.
It’s like someone designed a language to fix a bunch of obvious pain points.

Bluesky has grown a bit since I last shared some of my favorite lists and feeds here, so I thought it was time for a quick 🧵 so everyone new can find them as well!
I’m mostly interested in embedded dev with Rust, but a lot of these goes across the entire maker space, hobbiest or professionals!
