We've completed an important milestone: Ariel OS can now be built using the stable version of the Rust compiler. From the just-released version 0.2 on, you can just use any future #RustLang compiler to build your #embedded microcontroller project.

Certified rat moment.

"no_std" support landed on main branch.

Running TUIs on your microwave's display soon.

Trifecta Tech Foundation is now a member of the @rustfoundation!

Why? We believe that software must become safer; that this is paramount in critical infrastructure; and that #rustlang is an outstanding choice of technology for this purpose.

* Announcement * Memory-safe sudo to become the default in Ubuntu!

@ubuntu is supporting us to get sudo-rs ready for Ubuntu 25.10.

"Fuzz testing is incredibly useful, but the fuzzer is a black box; Does my fuzzer actually exercise the code paths that I think it should?"

@folkertdev uncovers the mystery in his new blog: https://tweedegolf.nl/en/blog/154/what-is-my-fuzzer-doing

Simulation results of how much a home battery could've saved me last year (with 2027 prices). No trading, just a simple charge when exporting and discharge when importing.

These results are... disappointing. A 10 kWh battery saves €190, but costs ~€4000. So it'd take 21 years to recoup.

Let's see how fast serde-json can deserialize 9gb of json :P

Maybe silly idea?

What if device-driver could also generate C headers? Maybe 'normal' embedded people would use it and publish it. Then we (the crab people) would get low level drivers for (almost) free!

We're happy to see adoption for zlib-rs skyrocketing. Especially stoked about rust tooling like cargo, gitoxide and rustup

Special thanks to @josh

People like to think Asimov predicted the current technology known as "artificial intelligence". They are wrong. It was Douglas Adams when a computer spent untold resources just to return an answer which is both irrelevant and poses further questions.

Does using Rust really make your software safer?

SIMD is neat because it's an area where a clever programmer can still beat the compiler. But it's also intimidating, and hard to see how all of those weird instructions can be used.

So, I'm writing a short series to show how we use SIMD to speed up zlib-rs.

https://tweedegolf.nl/en/blog/153/simd-in-zlib-rs-part-1-autovectorization-and-target-features

New blog series: @folkertdev shows how we use SIMD in the zlib-rs project.

SIMD is crucial to good performance, but learning how to use it can be daunting. In this series we'll show concrete examples of using SIMD in a real world project.

Part 1 explains how the compiler already uses SIMD for us, how to evaluate whether it's doing a good job, and how to use a more optimal version when the current CPU supports it.

Mijn dochter raakt haar kamer in Nijmegen kwijt

Wie heeft er tips?

Idk why, but a year on from getting my solar panels it still makes me happy I can grill chicken for free and purely from the sun

Say I would want to experiment with embedded linux, what would be a good board to get? Ideally it's relatively cheap and also very 'normal'. Performance needs are low.
