Home Infrastructure Part 1: Espressobin v7

I've been running DD-WRT on my router / WAP, a Linksys 1900ACS v2 for a few years. It's a fine router, but I'd been seeing some stability issues with the temperature sensor after setting up HomeAssistant's DD-WRT integration for detecting which devices are currently active on the home network.

I've been reading about single-board computers lately, alternatives to the Raspberry Pi. Back in Highschool I was fascinated by the PC/104 micro computer form-factor. The MIT Media Lab's wearable computer team used PC/104 boards for a few of their wearable computing platforms, and I've been interested in small computers running linux ever since.

The Espressobin is a router SBC with a built-in 3-port switch.

Architecture

Use Onion architecture
- Dependencies go inwards. That is, the Core domain doesn't know about outside layers
Use pipeline model to implement workflows/use-cases/stories
- Business logic makes decisions
- IO does storage with minimal logic
- Keep Business logic and IO separate
Keep IO at edges

Then mathematical neatness became a goal and led to pruning some features from the core of the language.

— John McCarthy, History of Lisp

If you prefer programming languages with a tidy and tiny core, you're in for a treat. This article drills down to the singleton primitive at the heart of Raku's metamodel ("model of a model") of a model of computation ("how units of computations, memories, and communications are organized")¹.

The reason I've written this article

It began with u/faiface's reddit post/thread "I'm impressed with Raku"². One of their sentences in particular stood out for me:
