My new job
I am happy to announce that I have joined a new startup called VectorWare. The linked website is currently very bare-boned, but the company aims to use Rust to improve the state of GPU programming.

Faster Rust builds on Mac
Did you know that macOS has a secret setting that can make Rust builds faster? It can also make Rust tests faster. It probably even has similar effects for other compiled languages such as C, C++, Go,...

Speed wins when fuzzing Rust code with #[derive(Arbitrary)]
If you are using #[derive(Arbitrary)] to fuzz your Rust code, update the Arbitrary crate to v1.4.2 to get some compile time reductions and possibly some fuzzing speed improvements.

How much code does that proc macro generate?
Rust’s proc macros are powerful but tricky, and have some compile-time costs. This post is about a new tool to help quantify and reduce some of those costs.

How to speed up the Rust compiler in March 2025

Streamlined dataflow analysis code in rustc
Sometimes I pick a crate in the Rust compiler and read through its code to learn about it and find things that I can improve. Often the improvements are small, but sometimes they snowball.

I don't like the phrase "democracy is fragile". A well-established democracy doesn't break easily. It takes years of undermining to break one. Maybe "democracy needs protection" or "democracy needs constant renewal" would be better.
