Some recommended books for improving as a software developer
Most software books are too language specific and go out of date too quickly. What I find has stayed with me are books about bigger concepts, such as systems thinking and complexity, and also so-called "soft skills" such as management and psychology.
These are all really about developing empathy for other people :)
In this article, I'll explain why implementing numbers with just algebraic datatypes is desirable. I'll then talk about common implementations of FFT (Fast Fourier Transform) and why they hide inherent inefficiencies. I'll then show how to implement integers and complex numbers with just algebraic datatypes, in a way that is extremely simple and elegant. I'll conclude by deriving a pure functional implementation of complex FFT with just datatypes, no floats.

| ### [2023-06-19] UPDATE: Just tried to use my instructions again on a fresh install and it failed in a number of places. | |
| ###. Not sure if I'll update this gist (though I realise it seems to still have some traffic), but here's a list of | |
| ###. things to watch out for: | |
| ### - Check out the `nix-darwin` instructions, as they have changed. | |
| ### - There's a home manager gotcha https://github.com/nix-community/home-manager/issues/4026 | |

| # I found some good resources but they seem to do a bit too much (maybe from a time when there were more bugs). | |
| # So here's a minimal Gist which worked for me as an install on a new M1 Pro. |
| { config, pkgs, lib, ... }: | |

| # This sway config is mostly based on https://nixos.wiki/wiki/Sway | |
| # which integrates sway with systemd in the style described here | |
| # https://github.com/swaywm/sway/wiki/Systemd-integration | |
| # and the replies in https://github.com/NixOS/nixpkgs/issues/57602 | |
| # with some individual packages added/removed and using sddm as the display manager. | |
| # | |
| # Take care to start the correct target as described by the sway proejct wiki. |
