Apparently Claude's C "compiler" is actually Python compiler since it allows returning a string from a function with a return type int. They should add this in the new C standard /s https://godbolt.org/z/of4nxj79c

Bad codegen for comparing struct of two 16bit ints, https://github.com/rust-lang/rust/issues/140167.

Excellent discussions about a simple problem in appearance: Comparing a struct with two `u16` could be achieved by comparing one `u32` (bits concatenation of both `u16`, both should be loaded in the same register). Turns out, despite being a nice optimisation, it’s rather complex!

Edit: it also works with `i16` and `i32` of course.

Who needs Graphviz when you can build it yourself?, https://spidermonkey.dev/blog/2025/10/28/iongraph-web.html.

SpiderMonkey has replaced Graphviz by a custom graph layout renderer for their internal devtools. This article explains how the algorithm works, step by step (inspired by Sugiyama et al.'s algorithm, used by Graphviz, but simplified and with more constraints).

Pretty neat!
