I'm also excited to run a workshop on WebAssembly (learn how to use Rust in your browser) and see the talks from @timClicks, @orhun and others!

I'll be speaking at Rust Asia in Hong Kong on March 28! Very excited to talk to other programmers about how Rust powers the CAD suite we're building at Zoo.dev. If anyone else is going, or lives in Hong Kong, say hi!

Many jobs I previously considered boring are now, since playing Satisfactory, really fascinating. When I meet someone who works in logistics, supply chains, warehouses, etc, I've got so many questions for them. Moving goods from producers to consumers through physical space is complex and playful.

If you're using vitest (JS) and you run tests in a describe directly, don't. They're not guaranteed to run before any setup you have in e.g. a beforeAll call. Instead, run your tests inside it.
This was causing a bunch of tests to pass when I ran my whole test suite (because some earlier test called its beforeAll), but fail when I focused on just one test (because beforeAll never ran)

Today, my coworker and I figured out a bug that's been annoying me for 6 months or so :)

This short article taught me a ton about page faults and measuring the impact of virtual memory. Also how to use perf. Strong recommendation.
Uses Rust, but isn't really about Rust, it'd apply just as well to any systems language. https://tverghis.space/posts/page-faults/

Are you passionate about frontend testing and releasing? We want you to help us kill bad releases of our CAD suite before they leave CI. We love testing and automation and releasing quickly. Come help us out. Happy to answer any questions! Reposts appreciated :) https://zoo.dev/jobs/4513852005?gh_src&gh_jid=4513852005

Helix, my preferred text/code editor released today. They release twice a year, so they're big releases. https://helix-editor.com/news/release-25-01-highlights/

I just deployed https://rustcombinators.com
It's just a fork of the excellent interactive Which Rust Combinator Should I Use tool from https://jethrogb.github.io/rust-combinators/, I did zero work on it. But I can never remember that URL. Hopefully a catchier URL helps other people find the tool.

Whoah! The USA has granted my team at Cloudflare a second patent for our work! I'm very excited to see my name next to a bunch of really talented engineers who taught me so much.

We're hiring! If you know a graphics/C++ engineer who wants to build a new CAD kernel at a fully-remote startup, please apply or DM me for more about the role!
The job is probably 2:1 ratio of C++ to Rust, but it can skew higher or lower depending on what you want to work on.

We're using docs.rs/miette for this, here's the (pretty straightforward) PR to integrate it. https://github.com/KittyCAD/modeling-app/pull/4574

Feeling very happy. My KCL tests used to snapshot a debug print of KCL errors. These were very hard to read. Now we're using the Miette crate to store a fancy, human-readable error instead. It shows exactly where in the KCL program the error is coming from. This will make debugging so much easier.

My talk from #RustConf is up! I talk about the history and current state of computer-aided design, why we're building a new programming language for 3D modeling, and the lessons I learned along the way.

OK it's definitely the tan call. https://github.com/adamchalmers/fp-repro if anyone is interested in a repro.

Today I learned that f64::tan (or maybe f64::to_radians?) produces different results (given the same inputs) on my ARM MacBook and on x86_64 Linux.
The math consistently returns -3.40476137196133 on one, and -3.4047613719613308 on the other. At least it's deterministic. Happening on both debug and release builds.

Does anyone know why this surprising Serde behaviour works? Why can JSON arrays and objects both deserialize into a Rust struct via the default serde derives? https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=00a0bfdf489e6964794caa4ddecdab9f
