Episode notes
Distro Trade-Offs
- Nix and Arch represent different trade-offs: Nix is more radical and reproducible while Arch is simpler but needs active maintenance.
- Choose a distro based on whether you want reproducibility (Nix) or a rolling, hands-on experience (Arch).
From E-Ink Hobby To Nerves Work
- Lars recounts discovering Nerves while exploring Elixir and building a tiny e-ink demo on a Raspberry Pi.
- That early project led him into the Nerves community and later professional embedded work.
Build Minimal Reproducible Images
- Use Buildroot (via Nerves) to produce minimal, reproducible embedded Linux images with AB partitions for safe OTA updates.
- Rely on Nerves' opinionated defaults to avoid fragile apt-like upgrade failures on devices.
