All 8 Elixir courses: OTP, LiveView, AI Agents, Ecto, Nerves, LiveBook, Nx, and more. Built for developers already shipping in production. LiveView refresh and Ash course both ship this year, included when they drop.
Anti-vibe-coding for Elixir developers. $299/year after the trial (regular price $350). Cancel before day 15 and nothing is charged.
About one tenth of all CVEs published by the Erlang Ecosystem Foundation come down to atom exhaustion. Jonatan Männchen explains how creating atoms from untrusted input can crash the BEAM, and the patterns to avoid it.
HexDocs pages are essentially user-controlled websites that can run arbitrary JS, and every public package used to share one origin. Eric Meadows and Jonatan Männchen explain why each package now gets its own subdomain, isolated via the same-origin policy.
Your AI agent shouldn't guess. AppSignal's MCP server feeds Claude or Cursor your Elixir app's real errors, metrics, and anomalies. It debugs from facts, not hunches. Triage incidents and pull stack traces in your editor. Free 30-day trial.
Mauricio Cassola introduces ex_ratatui, a new library for building terminal UIs in Elixir. It wraps Rust's ratatui renderer but gives you a LiveView-style API with mount, render, and handle_event callbacks. He walks through a counter app to show how it works.
What if you need a self-contained LiveView widget that handles its own events, PubSub messages, and URL params? Jakub Lambrych introduces a pattern combining a state struct, attach_hook, and a function component, so the parent view stays agnostic of the widget's internals.
What does it actually mean for a type system to be precise? José Valim uses one simple example to explore the trade-offs between simple and expressive type systems, and shares where Elixir 1.20's type system stands today.
Fully remote. Async. Low corporate overhead. We are looking for a Principal Elixir Engineer to own and scale our backend. We run a high-traffic online gaming platform (16k+ DAU, 62k+ daily matches) and are actively expanding into real-money gaming.
