Reflecting after the Rust All Hands: cargo-semver-checks is in a fascinating spot. We've never simultaneously had: - so many hard problems that must be solved at once - so many "this is hard but we're confident it'll work" solutions in flight at once Thrilling, but exhausting. But THRILLING 🦀

Sad that RustWeek is over, and glad I got to spend the week with so many wonderful people. Next time you are delighted by how a Rust feature works, say thanks to all these folks who spent the week hashing out every possible edge case! Can't wait for next year's RustWeek! #rustweek #rustweek2026

"You shouldn't punish me for entirely nonexistent citations because I haven't read the real ones either" is not the sparkling defence of your ethics that you think it is.

Hello from Rust Week 2026! The venue is a movie theater, so the organizers made a batch of movie posters customized to the event. Here's just one of them ✨ #rustweek2026 #rustweek #rustlang

If you're at RustWeek and would like a cargo-semver-checks sticker, come find me!

I'm working on cargo-semver-checks, and I realized that an edge case of one of my edge cases has an edge case that breaks my planned design. That means that so far, I'm having an average Saturday in cargo-semver-checks land 😅

I’ve been sharing this paragraph a lot

After six months of work and writing, The Sojourn Audio Drama Season Two Volumes Three and Four are now in production! Thank you so much for all your support! We’ll see you later this year with more news! #TheSojourn #scifi #audiodrama #sciencefiction #scifibooks

SO EXCITED!!!

One Friday night a few months ago, my family sat down to enjoy a TV show. We were surprised to see "Start your free trial." instead of "Continue watching." Things escalated from there! Enjoy this 100% true story, part of #aprilcools! predr.ag/blog/the-sel...

First time posting for #aprilcools this is about my time rice farming in Japan: xd009642.github.io/2026/04/01/M...

A new Rust language design post from boxy (my ???): www.boxyuwu.blog/posts/an-inc... TL;DR: coherence (which is responsible for the orphan rule about trait impls) causes problems with ecosystem lock-in. If we introduce the idea of named trait impls we might be able to do away with it!

I have availability for Rust coaching, or consulting on Rust strategy from early April; from a single call to ongoing 2 days/week. I can help your team get things done, adopt Rust and use it more effectively, or to accurately evaluate Rust as a new technology.

Reminder: April 1st is coming up. That means it'll once again be time for April Cools' Club, where we all write genuine, 100% true articles on topics outside our usual beat. Everyone is welcome to join the #aprilcools club! www.aprilcools.club

cargo-semver-checks v0.47 is live now ✨ Inside, you'll find: - a workaround for a Rust 1.94 rustdoc bug that caused crashes in some projects - 7 new lints Happy SemVer Sunday! github.com/obi1kenobi/c...

When someone says „Scientists do not want you to know“ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

Here's a tiny bit of hopium: In 2024 we were planning on adding 160 GW of renewable energy to the grid by 2030. As of the start of this year, we had added 100 GW and are planning on adding 220 GW more by 2030. (In 2022 we planned for 60 GW in 2030. We hit that by the end of 2023)

Important news! I am delighted to announce the launch of my new podcast: The Untitled History Podcast. It's me, and guests, falling down all the history rabbitholes you can imagine. Please, please spread the word, subscribe and listen. Because... SHIPS CATS!! cms.megaphone.fm/channel/the-...

⏰️ 1 day left to submit a talk! The #rustconf program is shaped by the Rust community — and the CFP closes tomorrow @ 11:59pm PST. If you’ve been building, experimenting, debating, or refining how Rust is used in practice, this is your chance to put that work!

A rare case of a great landing (you can reuse the airframe after landing) that wasn't necessarily also a good landing (you can walk away from the airframe after landing).

Hey chat is it good when your security audit recommends this?

Why was this code ever shipped?! This is from the second vuln, where keys' signatures aren't checked before they're stored in the trusted key store. Why would you ever ship a "TODO, actually validate signatures lol" in your secure messenger?!

Folks, there's an impersonation scam on Discord (and possibly elsewhere) that uses tech people's names and photos to slide into your DMs. If you get a friend request / DM from "me" out of the blue: (1) it's almost certainly not me (2) feel free to ping me here to check!

There’s so much demand for a T that’s so fundamentally disappointing.

cargo-semver-checks v0.46 was released earlier this week ✨ It comes with 45 *new* lints. Almost 20% of *all lints* are new in this release — this is wild!! Exponential growth, manifested. github.com/obi1kenobi/c...

We are excited to announce that we can successfully use Rust's standard library from the GPU. This has never been done before. www.vectorware.com/blog/rust-st... Supporting Rust's standard library enables existing Rust code to work on the GPU and makes GPU programming feel normal.

I just woke up from a nap and somehow while I was asleep, everyone on the bus has figured out we are not going to the right place

cargo-semver-checks is growing faster than ever: - 7 new releases, from v0.39 to v0.45 - 122 new lints, more than double last year's count - 4x reduction in lint execution time — some lints became up to 10x faster - across 26 (!!) rustdoc format versions predr.ag/blog/cargo-s...

i think a core beef that i have with a lot of this "automation is bad" sentiment lately is that there is no inherent moral good in laboring the story of humanity is one of invention, where we improve our conditions by building things that help us do more things more easily

I've been running an indie games studio for 15 years now, and it felt like a good time to boil down what I've learned into 4 pieces of advice: www.pentadact.com/2026-01-08-1... I hope it's of use, not least because goddamn I forgot how long blog posts take to write.

Haha thanks! You & @chadwhitacre.com & @sentry.io putting so much time & effort & money into @opensourcepledge.com & sponsorships was a big reason why I joined Sentry. It speaks positively and strongly about the company culture and motivations and people!

Job update: I'm going to start as a frontend dev at @sentry.io on February 16th! 🥳 Sentry has a stellar product I've enjoyed using, lovely people, and an excellent relationship with open source. I'm really looking forward to joining the team. A few open source FAQs... 1/🧵

prospective Pledge co's: idk it's a lot of money, will it really help with recruiting? prospective employees:

Trying to understand a public API with the Rustdoc source button only to get some internal macro is an awful experience.

SemVer is tricky in all languages. But in #rustlang it's easier than ever before! By the end of 2024, cargo-semver-checks' capabilities were growing exponentially: 30 -> 57 -> 120 lints. We now end 2025 with 242 lints — 122 new lints were merged this calendar year 🎉 The exponential continues!

Quick reminder that this is coming up. Lots of good questions have come in, so please take some time to go in and vote for the ones you care the most about!

Expert tech bloggers’ tips for writers who are just getting started writethatblog.substack.com/p/advice-for...

This week on #OpenSourceSecurity I chat with Dirkjan Ochtman and Joe Birr-Pixton about #Rustls. A lot has happened with Rustls in the last few years (and there's a lot more to come). Writing a TLS implementation is incredibly complicated, even when you don't have to worry about memory safety

Rust makes it easier to write correct programs by enforcing invariants at compile time. Memory safety provides a valuable correctness floor and Rust gives you tools to build your own safe and correct abstractions. Want to thank @sunshowers.io for regularly making this point!

$100m of solar panels saves a country 30 years of gas imports at 2024 prices for the same 1.5TWh of electricity generated That's a $3b saving in gas imports for each $100m of solar deployed Another one of my charts of the year

I love these posters #39c3

At the gpg.fail talk and omg #39c3 You can just put a \0 in the Hash: header and then newlines and inject text in a cleartext message. Won’t even blame PGP here. C is unsafe at any speed. gpg has not fixed it yet.

Ever seen one of these, and wondered *why* they work? 🧵 This is a so-called Bitonic sorting network, and the illustrations show the two common ways to implement them. From an implementation point of view the two methods are effectively the same, so which one you pick just comes down to preference.

Just want to share with my American friends how the Australians respond to a shooting tragedy. Action, rather than thoughts and prayers.

I'm allocating a little budget to sponsor some folks who do important FOSS work. If you know some people who aren't yet getting enough love yet, send me their accounts. Especially if they work directly on or adjecent to @typst.app @rust-lang.org and jujutsu (the vcs).
