308: Elixir Goes Gradually Typed

32 minutes

Elixir v1.20 has officially landed, marking a huge milestone as the language is now officially a gradually typed language, type checking every single line of code without requiring developer annotations, and even prompting some developers to drop Dialyzer entirely. HexDocs is rolling out per-package subdomains for improved browser security isolation, the Erlang Ecosystem Foundation has launched an Ecosystem Registry to help answer "who uses this?" for Erlang, Elixir, and Gleam companies, and the Lua library for Elixir is approaching its v1.0 release with a brand new pure-Elixir Lua 5.3 VM. On the security front, a sophisticated self-replicating worm called Miasma compromised 73 Microsoft GitHub repos by exploiting legitimate OIDC tokens and valid SLSA provenance, even weaponizing AI coding tools like Claude Code and Cursor, raising fresh questions about supply chain safety and whether Hex might benefit from a cooldown mechanism like the one Ruby just shipped, and more!
