NATS at Industrial Scale
Schaeffler built a NATS mesh across 100+ plants handling billions of messages daily. Jean-Noel Moyne & Max Arndt are showing how at MQ Summit: → No firewalls to open → 50+ apps on one backbone → Production-proven edge architecture https://mqsummit.com/
Ports and external process wiring
External processes can escape the BEAM, read this blog post for notes about how to get processes to play nice with supervision.

From Diplomacy to OTP: Mackenzie Morgan's Path to Erlang and Elixir
In this episode of Elixir in Focus, part of the SE4FP https://se4fp.github.io/2025/ warm-up series, host Adolfo Neto welcomes Mackenzie Morgan, a senior backend engineer at Level All. Mackenzie shares her journey into technology, which began with a focus on Japanese and International Affairs at university. She recounts how the “siren song of the computer lab” and a scheduling conflict between an algorithms class and a Japanese class ultimately led her to a computer science degree, a path she had already begun exploring through her contributions to the Ubuntu project as an undergraduate.
