@nikomatsakis.com could you post this gem also by yourself for bsky people smallcultfollowing.com/babysteps/bl...

I think about this post from @david.kolo.ski a lot. Also here's some notes from my last flight, and owwie ouch oof my thinking hurt gist.github.com/jamesmunns/9...

Nice blog post by @mre on Rust's alternatives to named, optional and variadic function arguments, and why they may be superior to adding new language features. https://corrode.dev/blog/named-arguments-at-home/

OH MY GOD WAIT ages ago i turned an lpd8 into a system usage monitor with the pads blinking and lighting up with network requests, drive io, cpu/ram load etc i might still have it somewhere . o O ( herdr controller )

Opus 5.5 is the most fun I've had with an AI model in a long time (and, yes I un-cancelled my Anthropic sub... well played)

My async compiler work got funded! So here's my first PR: github.com/rust-lang/ru... Roughly, it changes match x { true => foo(1).await, false => foo(2).await, } to match x { true => foo(1), false => foo(2), }.await This means the future will only have 1 state instead of 2

"wire fraud" would be a great name for a protocol testing library

Every programmer knows Dijkstra’s “Testing shows the presence, not the absence of bugs” and yet every programmer goes about their day pretending it isn’t true.

How we developed the world's first safety-certified product written in Rust – and why we went bare metal > Sonair certified ADAR One, the first safety-critical embedded system in Rust, using Ferrocene on bare-metal TI Sitara for robot safety sensors.

ok so it turns out discord is.. 80% there when it comes to interacting with agents. so many cool integration points. each thread even has its own identity, a-la pluralkit :)

New terminal multiplexer in town! 🎉 Powered by @ratatui.rs 🐀 🐑 herdr — run multiple AI coding agents in persistent terminal sessions and reconnect from anywhere. github.com/herdrdev/herdr #rustlang #ratatui #tui #terminal #multiplexer

re: "how is vibed shit more secure to run than random github repo": bsky.app/profile/fast... agents will leave vulns in by mistake/omission, not malice randos on github, in this climate, however... different story. yes the game has changed 🤷 adapt.

🎙️ Check out the new FLOSS Weekly podcast to learn about the growing Rust driver library, ways to build Rust stacks, and opinionated tooling. 🦀 ▶️ 𝗪𝗮𝘁𝗰𝗵 𝗘𝗽𝗶𝘀𝗼𝗱𝗲 𝟴𝟳𝟴: 𝗔 𝗧𝗼𝗼𝗹 𝗪𝗶𝘁𝗵 𝗢𝗽𝗶𝗻𝗶𝗼𝗻𝘀: www.youtube.com/watch?v=ah11... #RustLang #EmbeddedRust #FLOSSWeekly #FerrousSystems

My impression is that AI coding is on a "pick two of three" triangle: scope, ship speed, and correctness. Small tools are (speed + correctness) fast prototypes are (speed + scope) and big projects are (scope + correctness). Every project that tries to be all three degrades to "fast prototype."

some interesting stuff in here between the eyerolls. luckily academic philosophy is like high-altitude training for reading annoying people

I wonder if this will make people reconsider their stance or become even more defensive.

Incident Report: CVE-2026-LGTM nesbitt.io/2026/06/26/i...

Why is message passing better? Because it is closer to a purely functional style of programming, where messages come in and messages come out that are hopefully only determined by the state so far. You can build models for what should happen and then test the hardest parts

please enjoy — I won breathiest talk of 2026 and the year's not even over!

I'm biased because I helped write part of it (and @balbi.sh has continued adding even more info!), but I think the `embassy-mcxa`'s DEVGUIDE is probably one of the better references now for "how embassy HALs work and how to write a good one", if that's what you're in to. github.com/embassy-rs/e...

How did we end up in a place where I now need to clean up terrible LLM code? I hate this. The original guy also hasn't learned anything. I'm 70% sure the PR review I gave was just fed back into the LLM, which means that *every single problem* had to spelled out in the review. Is this the future?

maybe im egoizing but it feels LLMs expose the “island of agency” where on one side you have people who are in some kind of slop fever (including most of the boosters on here) and on the other side you have people falling into superstitious denialism. in the middle you can get so much done.

In a CRA webinar last week, I commented it is possible that C/C++ are a per se CRA violation, since C/C++ are insecure by design. An attendee replied "but C/C++ is what embedded use" and I said, more or less, "tough". Here's @gregkh.bsky.social on it: www.zdnet.com/article/rust...
