Another post on Dada, this time about how internal references work: smallcultfollowing.com/babysteps/bl...

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...)

New Dada blog post smallcultfollowing.com/babysteps/bl... -- things start to diverge from Rust in a deep way and I think the first where we start to see some real advantages to the Dada way of doing things (and some of the tradeoffs I made to achieve those advantages).

Third popcorn-sized Dada blog post: smallcultfollowing.com/babysteps/bl...

guys… we made a Super Bowl ad here’s how we did it: www.404media.co/watch-404-me...

I've learned by now not to make promises about my posting schedule, but I do find that posting things on my blog makes me happier. I'm going to see if I can bang out short posts that cover the things on my mind on a more regular basis.

New (very short) Dada post: smallcultfollowing.com/babysteps/bl...

Side projects keep me sane: smallcultfollowing.com/babysteps/bl...

Any lean-fanatics who can recommend a book that walks through building a prog lang in lean?

Things that suck: the UK ETA app. I mean, the concept, well whatever, they want to tax me and call it "security" fine, but can they at least make an app that doesn't take 5-10 minutes to proceed through each stage?

Me on 2026:

I'm having an incomprehensible problem: I WANT to open VsCode's Chat UI, and I can't figure out how! When was the last time that the problem was not being able to figure out how to get an AI extension to appear, rather than the reverse??

Second blog post from the Rust vision doc effort: blog.rust-lang.org/2025/12/19/w... Working through the data we gathered really helped sharpen my understanding here.

Are you in a safety-critical industry? Using the Rust programming language (@rust-lang.org) or would like to? Make your voice heard when it comes to what you'd like to see for Rust Project Goals! (survey link below)

Why can't contributors to Rust treat me like Claude does? Claude always has nice things to say about my brilliant insights.

OH: "weird and confusing compilation errors but not wrong runtime behavior" is the rust motto

First of many blog posts about the Rust vision doc process: blog.rust-lang.org/2025/12/03/l...

Here's the thing about "Find my Phone" alerts on iPhone. Until I have found the phone, I can't see it. Once I have found it, I don't want to see it. So why do they stay on there for an absurdly long time, despite my attempts to click them away? WHY?

New #rustlang blog post, about "move expressions", an idea that came up after my last post on ergonomic ref counting: smallcultfollowing.com/babysteps/bl...

How did I go through the last 28 years without ever seeing the music video for "The World Around" by Daft Punk? Amazing. www.youtube.com/watch?v=K0HS...

Pretty cool that Rust is big enough to take down the internet. :D

Congratulations Michele! Nobody worked harder than you. I don't envy you the challenge of figuring out how to navigate school funding in our current political environment, but I'm glad it'll be you helping to do it.

happy to share another production of the Rust Project Content Team. this time we sat down with Jack Huey and @nikomatsakis.com to learn more about what the Vision doc is! (link to video in next post)

Exciting news! Today, we announced the Rust Foundation Maintainers Fund: an initiative to provide consistent, transparent, long-term support for the developers who make Rust possible. Supporting maintainers = supporting Rust’s future. Learn more: rustfoundation.org/media/announ...

Anybody out there living in Somerville Ward 3? Take a good look at Michele Lippens for School Committee! She’s a working teacher (20+ years of experience) and she is passionate about education and inclusion. Just what you want on the committee. You can learn more at micheleforsomerville.com

New rust-lang blog post on explicit capture clauses, continuing to document thoughts about ergonomic ref-counting: smallcultfollowing.com/babysteps/bl...

New #rust blog post on how we could get types that cannot be forgotten, types that must be moved, async and const drop, and other fun stuff: smallcultfollowing.com/babysteps/bl...

New blog post arguing that we need to have a way to create handles that is both explicit *and* ergonomic around closures (even if we later have a fully automatic option, too). smallcultfollowing.com/babysteps/bl...

New blog post, "Symmetric ACP": smallcultfollowing.com/babysteps/bl... This post describes **SymmACP** -- a proposed extension to Zed Industries' Agent Client Protocol that lets you author extensions to AI tooling that can be combined orthogonally to one another.

My home of Missoula just voted to establish the pride flag as an official government flag of the city, thereby circumventing the state's asinine pride flag ban. 🏳️‍🌈 Missoula is once again showing how to fight back against policies that seek to erase the LGBTQ community.

I’ve been experimenting with Claude Code/Cline. Interesting how this changes the calculus for languages. Why pick one language over another if the AI is writing a lot of the code? Reviewability and local reasoning seem paramount. Efficiency and portability matter too. The rest? Meh.

How had I never heard of firedbg.sea-ql.org/blog/2023-12...? This cools cool! Is it still actively developed? Anybody tried it?

People always ask me “so is AWS using Rust?” Happy to be part of this article shining some light on how Rust is changing the way services are built in AWS.

All my jokes are inside jokes with me, myself, and I.

Today I’ll be teaching the middle school math classes at my daughter’s school. Wish me luck. Or maybe wish the kids luck! nikomatsakis.github.io/math-is-more...

Hey RustWeek! I talked to someone who had a company at RustWeek that could help with processing the data from the Rust Vision Doc survey. I think I have their name or card but I have a lot names and cards so I was wondering whether that person would see this message and reach out to me =)

Does anybody else feel that copilot's logo looks like a frog?

My favorite part happened on the way over. Five of us were taking an Uber to the venue and one of them I had never met, so I introduced myself. "We've been working together for 10 years," he said. "I'm Vadim Petrochenkov". As far as I know, it's the first time I ever laid eyes on the guy. Amazing!

I kinda love how goofy I look in this picture (front row left). What a great party!

New blog post in honor of Rust's 10th anniversary: smallcultfollowing.com/babysteps/bl...

This movie theater is truly the most inspired choice for a conference venue. #rustweek

The thing nobody tells you about vibe coding is that it is kind of boring just watching the LLM slowly walk through things, even on those occasions where it is not going off track. There has to be a way to make this more fun.

I’ve definitely noticed this.

I gotta hand it to the Boston @mbta.com. The red line is genuinely fast now. All those closures and repairs paid off.

Random hot take of the day: In the runup to Rust 1.0, I argued (unsuccessfully) that `unwrap` should be renamed to `assert_some` or `assert_ok`. I still think I was correct. 😠

Looking through old photos and I found this one of a whiteboard in Mozilla offices from Nov 2011. IIRC I was explaining early borrow checker designs to @dherman.dev and @pcwalton.bsky.social.

I’m late to the party but Susan Tedeschi rocks. Where you been all my life?? I didn’t realize how much I missed listening to blues.
