Atuin just keeps being 🔥📈

Reminder that the RustConf CFP closes tonight! I know most of us procrastinate until the last minute 😅 While you're at it, consider also submitting to Rust Forge and EuroRust 👀 If you're excited about a topic, I want maximum odds of hearing you talk about it! #rustlang

Friends! I'm on the job market now! I have a oodles of knowledge for all the software performance engineering tricks in Rust, Julia and other systems languages and would love to work with teams that are looking to skill up in those respects, from back ends to big data crunching!

Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust. In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

🎉 Rust turns 10! What a decade for us all 🥳 To celebrate, we’ve curated 10 must-watch talks from EuroRust. Let’s kick things off 👇 🧵 1/11

🦀 Predrag Gruevski – Build Bigger in Less Time: Testing Beyond the Basics Big codebases don’t survive on unit tests alone. Predrag shares advanced testing strategies that keep complex Rust systems reliable and fast to iterate on. 🧵 6/11 📺 Watch: youtu.be/3EFue8PDyic

Fly.io Note that mutexes acquired in an `if let` being held through the `else` block is something we fixed in Rust 2024. Didn't help since you were dealing with this last year, but hopefully that particular issue won't hit anyone else.

Experienced #rustlang engineers never break SemVer. Nobody needs cargo-semver-checks — just be more careful </s> I even *had left myself a note* that the next release needs to be a major bump. Too bad I only saw the note after cargo-semver-checks stopped the publish job!

Bad news -- I'm not going to be with my employer for much longer due to team relocation demands. If anyone has any leads for roles that would allow me to continue my Rust compiler work (in New York City), they'd be greatly appreciated.

If you're in a position to hire a compiler developer, rush it! Giving errs :^) the opportunity to continue working on Rust is probably the most impactful contribution that your company can make to the project.

New blog post + cargo-semver-checks v0.42 is out ✨ I found some unexspected sharp edges in the `#[target_feature]` attribute. They are getting fixed (teamwork! 🤜🤛), and cargo-semver-checks now also has lints to save you from footguns! predr.ag/blog/unsoundne…

Let's get 50 registrations sold in 25 days! Who do you know who knows Rust, or has always wanted to ever since they first heard about it?

Today Instant is releasing an API to let humans and agents spin up full-stack backends Each backend comes with database, sync engine, auth tools, file storage, as well as presence And it's all hosted on multi-tenant infra You can create millions of DBs in milliseconds

[1/6] Curious about Muon, but not sure where to start? I wrote a 3-part blog series called “Understanding Muon” designed to get you up to speed—with The Matrix references, annotated source code, and thoughts on where Muon might be going.

Python 3.14, or, πthon

I’ve noticed people who have good creative ideas usually know tons of things. Good researchers have read a lot of papers. Good musicians have listened to a lot of songs. Not only that, they generally have strong opinions about what’s good/bad out there. I wonder why? I
