2025 Recap: so many projects
I’ve been working on so many projects in 2025, I thought it was important for me to make a recap, if only just to clear my head. There are many, many, many things to go through and we don’t have a sponsor today, so I’m gonna start right away with facet! facet facet is a project that I started working on in March of this year — that’s right, it’s only been ten months, yet it feels like an eternity.
Introducing arborium, a tree-sitter distribution
About two weeks ago I entered a discussion with the docs.rs team about, basically, why we have to look at this: When we could be looking at this: And of course, as always, there are reasons why things are the way they are. In an effort to understand those reasons, I opened a GitHub issue which resulted in a short but productive discussion. I walked away discouraged, and then decided to, reasons be
What Else Could Container Queries... Query?
How far can we really go with container queries? There are dozens of media queries now, so what if there were dozens of container queries as well? What could we use them for?

Does Dioxus spark joy?
Note: this article is adapted from a presentation I gave at a Rust Paris Meetup — that’s why it sounds a little different than usual. Enjoy! Good evening! Tonight, I will attempt to answer the question: Does Dioxus spark joy? Or at the very least, whimsy. What’s Dioxus, you ask? It is first and foremost a name that is quote: “legally not inspired by any Pokémon”. Even if the author concedes in a H

Engineering a Rust optimization quiz
There are several Rust quizzes online, including one that’s literally called the “Unfair Rust Quiz” at https://this.quiz.is.fckn.gay/ , but when I was given the opportunity to record an episode of the Self-Directed Research podcast live on the main stage of EuroRust 2025 , I thought I’d come up with something special. The unfair rust quiz really deserves its name. It is best passed with a knowledg
How we found a bug in Go's arm64 compiler
84 million requests a second means even rare bugs appear often. We'll reveal how we discovered a race condition in the Go arm64 compiler and got it fixed.
Making our own spectrogram
A couple months ago I made a loudness meter and went way too in-depth into how humans have measured loudness over time. Today we’re looking at a spectrogram visualization I made, which is a lot more entertaining! We’re going to talk about how to extract frequencies from sound waves, but also how my spectrogram app is assembled from different Rust crates, how it handles audio and graphics threads,

The power of play
When Designer Advocate Laura Fehre set out to design a digital nail salon, she had a vision in mind. Nailing it, however, meant letting go of perfection and letting herself play.
The promise of Rust
The part that makes Rust scary is the part that makes it unique. And it’s also what I miss in other programming languages — let me explain! Rust syntax starts simple. This function prints a number: fn show ( n : i64 ) { println! ( "n = {n}" ); } And this program calls that function — it looks like any C-family language so far, we got parentheses, we got curly brackets, we got, uhh…

Solo Development: Learning To Let Go Of Perfection — Smashing Magazine
The best and worst thing about solo development is the “solo” part. There’s a lot of freedom in working alone, and that freedom can be inspiring, but it can also become a debilitating hindrance to productivity and progress. Victor Ayomipo shares his personal lessons on what it takes to navigate solo development and build the “right” app.

Catching up with async Rust
In December 2023, a minor miracle happened: async fn in traits shipped. As of Rust 1.39, we already had free-standing async functions: pub async fn read_hosts () -> eyre :: Result < Vec < u8 >> { // etc. } …and async functions in impl blocks: impl HostReader { pub async fn read_hosts ( & self ) -> eyre :: Result < Vec < u8 >> { // etc. } } But we did not have async functions in traits:

Break Stuff on Purpose
“A complex system can fail in an infinite number of ways.” -“Systemantics” by John Gall Incidents are stressful but inevitable. Even services designed for availability will eventually encounter a failure. Engineers naturally find it daunting to defend their systems against the “infinite number of ways” things can go wrong.

Design’s journey towards accessibility
Design can have a significant impact on delivering accessible experiences to our users. It takes a cultural shift, dedicated experts, and permission to make progress over perfection in order to build momentum. We’ve got a long way to go, but we’re starting to see a real shift in our journey to make GitHub a true home for all developers.
TV Spatial Navigation
Very often, when developing user interfaces, a lot of focus is given to the visuals, as that’s what primarily gets a user’s attention. However, other aspects are equally impactful for making the experience great but can be overlooked, like the user’s input – how the user interacts with the app. It is completely understandable that it might go unnoticed; most of the time, the platform, say Windows
