[AI summary] The article discusses the author's experience of running Lean, a pure functional programming language, on an ESP32 microcontroller for a project involving LED control. Despite Lean's purity, the author utilized its monadic features to handle impure operations like GPIO manipulation and delays. The project involved significant optimizations, including custom bit-banging for the WS2812 LED protocol and reducing code size through various techniques. The author also outlines future directions for the project, including potential improvements in compilation, hardware support, and further optimizations. |

I recently purchased a new laptop (Dell XPS 13 9370) and needed to install Arch onto it. I thought I'd finally document the steps I took because I always seem to forget what I did the last time (one of the joys of Arch is that it rarely needs to be reinstalled). There are a lot of helpful guides online about different installation setups, but I could never find one that met all of my requirements: |
