Hi Everyone!

We're launching Code BEAM Europe 2026 on 21-22 October in Haarlem, NL (and virtually). It is a 2-day technical conference for engineers and developers working with Erlang, Elixir, Gleam, and the BEAM ecosystem.

Speakers

We're doing another Ash Conference, once again in Varberg Sweden, the day after goatmire! 🎉Tickets are not yet available, but we're looking for talk submissions. Submit your ideas, big or small 😎

What we're after:

I’ve spent the last few months working on the generation engine behind Ferrum Labs, which is currently in beta.

Our company recently needed to get client SDKs in PHP, Python, and Java for an OpenAPI spec we were working on.

It was an awesome pairing session where he showed me everything, from his new tool (Crit), to his custom skills, commands, and workflows.
