Lars Wikman, Elixir developer and Nerves contributor, joins Jerod Santo and Adam Stacoviak to talk embedded Linux, home automation, and the kind of hardware headaches that only surface when you push consumer boards past their limits.
The conversation covers Nerves, the Elixir framework for building embedded systems, alongside real-world use of Home Assistant, ZimaBoard, and n8n for self-hosted automation. The 4 DIMM problem is not a metaphor. It is a specific hardware constraint that shapes how Wikman architects his home lab, and the reasoning he walks through is worth the full runtime.
This episode earns its length through technical specificity. If you are building anything on BEAM outside a web server, or if you are trying to understand where Elixir fits in the IoT stack, Wikman is one of the few practitioners talking about it in public.
