The OCaml Planet

Rust promises to empower everyone to build reliable software, but its unique features create steep learning curves. In this talk, Will Crichton presents four years of research into evidence-based tools that help both novices and experts work more effectively with Rust's complexity, including: - Ownership visualization: Interactive diagrams showing permissions (read/write/own) that help students understand borrowing better than rule-based explanations - Trait debugging: A graphical tool for navigating complex trait inference trees when compiler errors become unreadably long - Program slicing: Using Rust's type system to automatically highlight only code relevant to specific variables All tools discussed are open source and available for use.

I’ve been thinking about terminal-based GUI applications recently and decided to give notty a try.

The FreeBSD workers have been getting [slower]( (https://github.com/ocurrent/opam-repo-ci/issues/449): jobs that should take a few minutes are now timing out after 60 minutes. My first instinct was that ZFS was acting strangely.

I’ve taken a few days off, and while I’ve been travelling, I’ve been working on a personal project with Claude. I’ve used Claude Code for the first time, which is a much more powerful experience than using claude.ai as Claude can apply changes to the code and use your build tools directly to quickly iterate on a problem. In another first, I used js_of_ocaml, which has been awesome.
