Write embedded drivers without the MCU in your dev loop. Pico de Gallo turns a Pi Pico 2 into a USB-attached I²C/SPI/UART/GPIO/ADC/1-Wire bridge, so your driver is just a cargo run binary talking to real silicon from your laptop. Build one for your chip → balbi.sh/posts/writin...

Just arrived in the Netherlands for #RustWeek. I am incredibly excited to be heading back this year for a whole week of #Rustlang events. My experience last year set a high bar: fantastic host city (#Utrecht), great venues, and flawless organization (#RustNL). It’s a brilliant event.

This paper finds that Rust on an microcontroller costs you about 10% extra flash space, actually saves you a bunch of RAM, and takes no extra time to deliver (as compared to C). Seems about right - especially as the C version needed a heap and the Rust version did not. arxiv.org/pdf/2604.25679

> Arm and Ferrous Systems bring Rust to Cortex-R82AE, enabling memory-safe, high-performance real-time systems for physical AI Working on this has very rewarding and I can't wait to see what you build on top of these building blocks. developer.arm.com/community/ar...

** Speaker announcement ** Catch Cliff L. Biffle's talk 'Common Pitfalls of Rewriting Things In Rust' at RustWeek 2026! Info & tickets: 2026.rustweek.org/talks/cliff/ See you in Utrecht May 18-23, 2026! #rustweek2026 #rustlang

wanna hear about what it's like teaching Rust in higher education? learn about the embedded scene? the hippy lore of unconfs? all that and more in the interview with Bart Massey! (video below)

🚀 Ferrocene 25.11.0 is out – and yes, it’s open source! Ships our first IEC 61508 (SIL 2)-certified subset of core, enabling certifiable Rust for safety-critical systems across multiple architectures. ⚙️ + updates from Rust 1.89 & 1.90. 🔗 Release Notes: public-docs.ferrocene.dev/main/release...

It's time for the State of Rust Survey! The Rust Project invites you to take this year’s survey, whether you have just begun using Rust, you consider yourself an intermediate to advanced user, or you have not yet used Rust but intend to one day 🦀

🦀 I've improved the implementation behind all the string formatting macros in Rust: println, panic, format, write, log::info, etc. (Everything using format_args!().) They will compile a bit faster, use a bit less memory while compiling, result in smaller binaries, and produce more efficient code! 🎉

“We adopted #rustlang for its security and are seeing a 1000x reduction in memory safety vulnerability density ... with Rust changes having a 4x lower rollback rate and spending 25% less time in code review, the safer path is now also the faster one.” security.googleblog.com/2025/11/rust...

Today we published bzip2 version 0.6.0, which uses our rust implementation of the bzip2 algorithm, libbz2-rs-sys, by default. The bzip2 crate is now faster and easier to cross-compile.

No. C++ is not “under attack” (www.theregister.com/2025/03/02/c...). It’s sad, because it reduces the likelihood of (or pushes back) any real progress on the topic.

Today I published arm-targets, a Rust crate that looks at your target string and lets you mark code as only working on specific versions of the Arm architecture. Ideally Rust would have built in target features for this, but it doesn’t. crates.io/crates/arm-targets
