Lars Wikman, Elixir developer and Nerves contributor, sits down with Jerod Santo and Adam Stacoviak to work through a specific hardware constraint: running embedded Linux on a ZimaBoard with exactly 4 DIMM slots and making Home Assistant behave. The episode is titled 'The 4 DIMM Problem' for a reason, and that reason is more interesting than it sounds.
The conversation covers Nerves, the Elixir framework for building embedded systems, and how it intersects with real home automation workflows using Home Assistant and n8n. Wikman also gets into Linux distro hopping, which means this is not a theoretical discussion. These are choices with consequences on physical hardware.
The full episode runs longer than the summary, and the technical detours, including BEAM Radio and Wikman's karate practice, are not filler. They connect back to how he thinks about systems. Read the show notes, follow the Nerves project link, and listen to understand why Elixir keeps showing up in places where reliability is not optional.
