Any contribution would be most welcome, even if it is just a one-time "thanks" for past work. :-) github.com/sponsors/Bur...

The Rust Style Guide used by Google has been open sourced! google.github.io/styleguide/r...

regex 1.13 now has a `regex!` macro (NOT compile time regex) that encapsulates the common pattern of using something like `std::sync::LazyLock` to ensure it only compiles ~once. github.com/rust-lang/re...

Jiff has been added to blessed.rs!

Plausibly low hanging fruit for improving substring search performance in Rust's standard library! github.com/rust-lang/ru...

Improving Miri is so critical. Thank you Tiffany!

Thanks for all the kinds words from old fellow Lobsters users. :-)

My new NAS build. My previous NAS was in continuous operation for about 10 years. It served me well, but it was time for an upgrade. pcpartpicker.com/user/burntsu...

wow

I love to see it! I'm curious if they will write the regex engine in Rust too. :-) github.com/uutils/grep

My son Murphy getting a successful POST on his first attempt. He doesn't know how good he has it. youtu.be/-HBOBskFMVg?...

The number of times in the past few weeks that I've said out loud to my wife, "I was talking to Chat about yadda yadda yadda" (Chat is short for ChatGPT) in the past few weeks is quite remarkable. I'm just waiting for the first time she says it. That will be a major milestone unlocked.

This is good.

I've added an AI policy to ripgrep that was shamelessly copied from uv's policy. I plan to add this to the rest of my projects, but if anyone wants to offer feedback on wording, now would be a good time! github.com/BurntSushi/r...

Why don't Jiff's strftime and strptime routines validate the format string separately from formatting or parsing a datetime? github.com/BurntSushi/j...

What it means that Ubuntu is using Rust, new blog post with some thoughts spurred by Jon Seager's excellent keynote at @rustnationuk.bsky.social (smallcultfollowing.com/babysteps/bl...)

Finally got around to migrating off of CoC to the native neovim LSP client. And while I was at it, I ported my entire vim config over to Lua. It was quite a bit more work that I thought it would be! It's been over a decade since I've written Lua, but it's a dream come true compared to Vimscript.

uutils has now fully migrated off of Chrono (which is now soft-deprecated) to Jiff! github.com/uutils/coreu...

Alex Pretti’s last words were “are you ok?” said the woman next to him who ICE also pepper sprayed in the face.

“Floating-Point Printing and Parsing Can Be Simple And Fast” The fastest known floating-point printer and parsing algorithms - fixed-width printing, shortest-width printing, and parsing, all in 400 lines of Go. research.swtch.com/fp research.swtch.com/fp-proof

I've updated the rebar benchmarks, and .NET's regex engine in v10 is right about on par with Rust's regex crate! Nice work! (rebar is, I believe, the most comprehensive public regex benchmark in existence.) github.com/BurntSushi/r...

First time seeing this and it is really great! abseil.io/fast/hints.h...

so pumped for the ty beta to finally be here, we did so much great work it rules! astral.sh/blog/ty

** Speaker announcement ** Our next speaker is Andrew "BurntSushi" Gallant! Andrew is a member of the Rust project and maintains many important crates. Info & tickets: 2026.rustweek.org Do you also want to give a talk? Our CFP is open. See you in Utrecht in May! #rustlang #rustweek2026

🦀 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! 🎉

ripgrep 15 is out! Mostly a host of bug fixes, particularly around gitignore. Some minor perf improvements. A couple small features. And (partial) Jujutsu support for gitignore. github.com/BurntSushi/r...

The crates.​io team was notified of two malicious crates (with similar names as legitimate crates) which were actively searching file contents for Etherum private keys, Solana private keys, and arbitrary byte arrays for exfiltration. See the blog post for details: blog.rust-lang.org/2025/09/24/c...

Happy 10 year anniversary to this tweet! Has memory safety in C++ been solved yet? x.com/CppCon/statu...

Found what appears to be my oldest game save on a physical memory card. From about 18 years ago! This is from The Simpsons: Hit and Run. On a GameCube memory card. I do probably have some N64 memory cards lying around... Hmmm.

We received reports of a phishing campaign targeting crates​.io users. Do not click on links asking to authenticate to protect your account. More information: blog.rust-lang.org/2025/09/12/c...

FYI, I got an obvious phishing attempt in my inbox from `security@rustfoundation.dev` that was masquerading as a security breach notification. It made it past gmail's spam filters. The link goes to the `github.rustfoundation.dev` domain.

Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry. We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".
