Some people have asked if they could copy the text. And yes! I've marked the file as CC0 to explicitly allow you to.

Anyways, I've been thinking about AI use in my projects and I've written a guideline for it that severely limits what you're allowed to do with them when interacting with the project. github.com/diondokter/d... I might copy this to some more repos.

So, a major through-line of computer science over the decades has been the ever increasing abstraction level. We (generally) don't worry about individual bits and clocks anymore like in the early days. It's been said that LLMs are simply the next step in this evolution.

In our data compression projects, we sometimes hit limitations in Rust itself and in the surrounding tooling. Folkert covers our contributions to the compiler and shows how we have become increasingly comfortable fixing these issues ourselves: trifectatech.org/blog/fixing-... #rustlang #opensource

Ok, yeah, but what even *is* a 12-bit little endian value?

I'm thrilled to announce that the next target of #Ubuntu's oxidization plan will be ntpd-rs! We will be funding the @trifectatech to build new features, enhance security isolation, and ultimately deliver a unified, memory-safe time synchronization utility for the Linux ecosystem for NTP, NTS […]

I'm super happy! After a month of hard work, the Device-Driver Specification Language (DDSL) is working and merged into device-driver! I've also been polishing up the playground, so now you get to see both! device-driver.com/playground/ (note the new swanky custom domain 👀)

Fun stat: There are now 30 drivers published on crates.io using device-driver! crates.io/crates/devic... There are a bunch more, but they've never been published and are locked in proprietary codebases :P

I wrote some thoughts about Rust and how you can use it to talk to your hardware. TL;DR: Read your own docs, like your users have to. Seriously. Go read them. ferrous-systems.com/blog/hardwar...

Interesting Rust position for those looking for one! ferrous-systems.com/blog/ide-com...

EtherCrab 0.7 is out! Release post here: wapl.es/ethercrab-0-7/ A smaller release, but still a few quality of life improvements. #ethercat #rustlang #rust

Achievement get: First real AI slop PR on one of my projects!

"Ok, but what subset of your requirement is the actual requirement?"

Interesting read, especially for those who do embedded and encounter inline asm regularly!

There's no possibility to have a dependency included when a feature is *not* selected in Rust, right? I'm hunting deps and want to get rid of using hashbrown. If the 'std' feature is active, the std hashmap should be used and hashbrown should be ignored.

I've been listening to Delta Goodrem for over 10 years now. She's such a good singer! And apparently she's gonna come out for Australia this next Eurovision. Had to give the song a couple of listens, but I really like it :) youtu.be/EUMCr1pnaMY

ntpd-rs is coming to Ubuntu! In RustNation's closing keynote Canonical announced that we are preparing ntpd-rs, our Network Time Protocol implementation, for Ubuntu. Watch the keynote here: www.youtube.com/watch?v=WOA4... @jnsgr.uk @rustnationuk.bsky.social @ubuntu-ls.bsky.social #rustlang

One way of ensuring cancellation safety in async Rust is just by consuming the object... struct Foo; impl Foo { async fn bar(self) -> Self { ... } } Cancel? No more Foo for you. Foo could be a zst token too that you have to pass around (like the CS token). Annoying API, but a correct API

Gave a full conference talk on a 320x240 screen today. Running Rust & Ratatui 🦀🐁 RustNation UK was amazing, thanks everyone! ♥️ #rustlang #ratatui #conference #rustnation #rustnationuk

Pssssst, psssst... Hey kids, wanna see the embassy executor running on a GPU?

Congrats everyone! My submission didn't quite make the cut, but hopefully that sets a high bar for the talks that did make it in 😉 I will be at the conference! Hope to see you there!

Hell yeah, Cortex-R (ARMv7-R) support in probe-rs :D github.com/probe-rs/pro...

Ok bit-order has been nuked I'm only gonna add it back when I have a physical device in front of me that uses MSB0

Ok, I think I'm just gonna remove bit order support from device-driver and assume everything is Lsb0. It's just so weird my brain can't handle it and I've never seen it be used. And if it's really required, well then the register interface implementation can reverse the bits.

Wow, realisation: Time of humans is becoming a currency. The matplotlib project requires a human to create new PRs, not just an LLM. This isn't weird, it's very normal. But the time of a human is used as a currency here. It adds a nontrivial cost to filter out (likely) bad submissions.

whereas, the pitch for genAI is to spend gravity bending amounts of money and resources to make copies of things we already have. it's a completely baffling idea that inverts all prior ideas of what good technology or business looks like

historically, tech was an infinite money printer because you can write a program once and then sell it or its utility unlimited times. you can keep building atop existing things and not have to duplicate effort on remaking things that already exist

The long sections of drum and bass present at the start and end of EDM (remixes) are the preamble and postamble of music

Does anybody know of a simple programming language that can be *translated* into other languages like Rust or C? (So no runtime/VM/engine) I need something with simple control flow, integer math and bit manipulation. I want to add some custom logic support into device-driver at some point.

Cool, migrated the first device-driver error from miette to annotate-snippets. I can show patch suggestions now! :D It's more work and code to write though and the API is not always clear on how it wants to be treated. But I like the results better.

Was testing out the annotate_snippets crate. For a split second I thought I had a compile error. So, it seems to be working! (annotate_snippets is the crate rustc uses/is gonna use for reporting errors)

Ok, so custom language for device-driver... What should it be the extension and name? .ddlang .ddsl (device-driver specification language) .ddd (device-driver description) It shouldn't overlap with anything popular that already exists... Any suggestions?

When using LLMs, it's very important to give clear instructions. Spec-driven development is the future. For example, a clear prompt to add two numbers could look like: ADD a TO b ON SIZE ERROR DISPLAY "Error" This specifies the overflow as well.

Zlib-rs is now feature-complete! We've released v0.6, the first version with a stable and complete API. The blog post has the details. With thanks to our maintainer Folkert de Vries, our contributors and @sovereign.tech. trifectatech.org/blog/zlib-rs... #rust #rustlang

Seems like the compiler gets mad when you have an enum with a reference field, that derives Debug and you then ask it to be repr(packed(1)) ICE: github.com/rust-lang/ru...

Ok, so when you read online "don't use chumsky for lexing, it's a bit slow", they're understating it! The same token output on ~60KB of text: Chumsky - 24ms 2.4 MB/s Logos - 0.45ms 130 MB/s That's 50x faster! Chumsky is still great for parsing though! Also it gives nicer/better errors than logos.

It appears the northern lights have made it over here. Very faint, can't really see it with the naked eye, but my camera can. Add note to myself: Travel up to the Arctic some time to really see it.

Lolol > Trump: Greenland is undefended! > Some countries: *send a handful of soldiers to Greenland to scout for a larger mission* > Trump: How dare they! So dangerous! Also, the US has been the only country threatening to invade Greenland. China and Russia haven't. So who's the bad guy?

Turns out writing a lexer and parser for device-driver is kinda fun! Makes it really appealing to ditch KDL. Lots to learn! I went to a pleb 'applied' university, so didn't get any courses with this stuff. Chumsky seems like a good bet. It's been treating me well so far.
