🎙️ Hugo Baraúna, dev advocate at Livebook/Dashbit and co-founder of Plataformatec, will share how Livebook Teams powers the deployment of Livebook apps.

He’ll walk through the architecture that bridges notebooks and production, perfect for anyone building data-driven Elixir tools.

Since the YOLO library now supports custom models, I created a guide showing how to fine-tune YOLO models for your specific use cases. The guide demonstrates transforming a generic 80-class detector into a specialized system (using soccer match analysis as an example) and integrating it with the Elixir YOLO library.

This fine-tuning approach applies to various industries where domain-specific object detection is needed - sports analytics, manufacturing QC, etc.

https://mtlynch.io/notes/gleam-call-elixir/

One of Gleam’s flagship features is that it can call Elixir code and libraries, but I couldn’t find any examples of how to do that. I wrote a simple example of calling an Elixir library from a Gleam project, based on my beginner’s understanding of the Gleam/Elixir/Erlang ecosystem.

Britton Broderick’s talk “Test-Driven Elixir: The Fast Track to Leveling Up to Senior Engineer” shows how mastering testing is your secret weapon for career growth 💪 ✅ Write tests first to design better code ✅ Clarify requirements before you build ✅ Think like a senior engineer from day one Perfect for early-career devs ready to break through to the next tier! https://elixirconf.com/#tickets
