300: Celebrating 300 with José Valim

ThinkingElixir.com — Tue, 21 Apr 2026 04:15:00 -0600

It's Episode 300 — a milestone just under 6 years in the making! To celebrate, we kick things off with a fun song, then dive into the news: the Localize library v0.15.0 brings locale-aware formatting and Unicode CLDR data to Elixir without any compile-time code generation, a new library called Reach builds program dependence graphs for Elixir and Erlang to help coding agents and static analysis tools understand your codebase, Tidewave gets exciting updates including voice input with click-to-add context and the ability to install it as a PWA, the ErlEF has opened its 2026 board elections with voting running May 8-15, and more! Then we sit down with José Valim for an in-depth interview covering Elixir v1.20, the latest progress on the set-theoretic type system, the story behind Tidewave, and how AI is — and isn't — changing development on Elixir itself.

https://github.com/elixir-localize/localize – The Localize library v0.15.0 was released — a locale-aware formatting, validation, and data access library for Elixir built on the Unicode CLDR repository. Consolidates the ex_cldr_* family into a single package with no compile-time code generation; all CLDR data loads at runtime and caches in :persistent_term.
https://x.com/dan_note/status/2044763774146466053 – Announcement tweet for the new "Reach" library — a program dependence graph tool for Elixir and Erlang.
https://github.com/dannote/reach – Reach builds a graph of data flow, control flow, and side effects in your code so you can trace values to their origin, find tainted paths from user input to dangerous sinks, or check if statements can be safely reordered. Works on Elixir/Erlang source and compiled BEAM bytecode.
https://x.com/josevalim/status/2044483950089834990 – José Valim demos new Tidewave updates — voice input now works, and while talking you can click on elements to build context into a message. Also works when referencing lines of code in code reviews.
https://x.com/josevalim/status/2044060492704948305 – Tidewave can now be installed as a browser PWA (Progressive Web App).
https://bsky.app/profile/david.bernheisel.com/post/3mjkl6ck4a22c – David Bernheisel shares a "frustration driven development" Zsh autocompletion script for mix tasks — announcement and discussion post on Bluesky.
https://github.com/dbernheisel/dotfiles/blob/master/.local/bin/_mix – The Zsh autocompletion script for mix tasks. Runs mix help to find tasks and their descriptions, then mix help {task} for switches, feeding results into the Zsh completion engine with per-project caching.
https://erlef.org/blog/eef/election-2026 – The Erlang Ecosystem Foundation has announced its 2026 board elections. Candidacy submissions close May 7th (23:59 UTC), voting runs May 8–15. Must be a paying, contributing, or managing member to participate.

267: Dive into Tidewave Web with José Valim

ThinkingElixir.com — Tue, 26 Aug 2025 04:15:00 -0600

News includes the exciting announcement of Tidewave Web, a new AI-powered service that runs locally in your development environment with an AI chat sidebar that can directly interact with and modify your Phoenix and Rails applications. José Valim joins us for a deeper dive into Tidewave as well! We also cover a comprehensive new ElixirLang blog post about interoperability in 2025 that explores all the ways Elixir and BEAM can work with other languages and runtimes, from traditional NIFs and Ports to newer options like AtomVM for microcontrollers, Popcorn for browser deployment, and integrations with Rust, Zig, Python, and C++. Additionally, Livebook Teams has officially launched out of beta with SSO support and enterprise features, Oban v2.20.0 brings job updating capabilities and improved plugin supervision, PhoenixAnalytics v0.4.0 adds 12 new themes and drops the DuckDB requirement, LiveView v1.1.7 introduces a new stream_async function, and more!
