NixOS Homelab on a ThinkCentre M90Q

This is how I set up my homelab, step by step, in roughly the order I actually did it. Each step builds on the previous one. Read until you hit where you're at and stop.

Step 1: A minimal NixOS flake that just works

The first thing to get right is flake.nix. This is your entire system config: users, networking, firewall, packages, services. Everything in one file.

Here's a minimal starting point. Set a static IP so your other devices can always find the server. Enable Docker and SSH. Disable sleep. That's it.

What is the appeal of dynamically-typed languages?

Kris Nuttycombe asks:

I genuinely wish I understood the appeal of unityped languages better. Can someone who really knows both well-typed and unityped explain?

I think the terms well-typed and unityped are a bit of question-begging here (you might as well say good-typed versus bad-typed), so instead I will say statically-typed and dynamically-typed.

I'm going to approach this article using Scala to stand-in for static typing and Python for dynamic typing. I feel like I am credibly proficient both languages: I don't currently write a lot of Python, but I still have affection for the language, and have probably written hundreds of thousands of lines of Python code over the years.
