Bugs Rust won't catch
In April 2026, Canonical disclosed 44 CVEs in uutils, the Rust reimplementation of GNU coreutils that ships by default since 25.10. Most of them came out of an external audit commissioned ahead of the 26.04 LTS. I read through the list and thought th…

The cleverness of the text is staggering. Superficially it reads as an epistolary exchange between two (possibly former) lovers, Charlotte and Charlie. At…

Why Does “=” Mean Assignment?
Take the following code: a = 1 a = a + 1 print(a) A common FP critique of imperative programming goes like this: “How can a = a + 1? That’s like saying 1 = 2. Mutable assignment makes no sense.” This is a notation mismatch: “equals” should mean “equality”, when it really means “assign”. I agree with this criticism and…

Everyone should know SIMD
SIMD has a reputation for being complex. I've met many very good software engineers who dismiss it as something too complex to learn or a niche optimization meant for only the highest-performance software, not useful in everyday programming.

There's no reason for software to be slow anymore
The other day, I saw a viral tweet saying that people talking about how LLMs are causing slow, bloated, code are going to eat crow once they re-write everything in super-optimized assembly. We're not quite at the point where we want to write everything in assembly , but some variant of what Nolan Lawson said about…
