Hit a build error with wasm-pack. Solution: downgrade to 0.9.1.

Spent the day figuring out Rust traits. Here’s the mental model that finally clicked for me.

Emacs suddenly started throwing file-missing doing vfork errors on startup. Turned out to be an emacs-sqlite compilation issue.

Was reading about RSS vs Atom feed formats. Found out RSS 2.0 has a fundamental problem with relative URLs.

Found an interesting article about Go slice search vs map lookup performance. The TLDR surprised me.

Learned that mod.rs files are the old way. Rust 1.30+ has a better convention.

Debugging Rust macros is painful. Compiler errors point to the macro invocation, not what it generates. cargo-expand fixes that.

Came across this classic post about computer performance numbers. Really puts things in perspective.
