Fonts

Installing fonts on Ubuntu is manual.

On macOS you can just double click, or automate it via brew:

brew cask install cask-fonts
brew cask install font-hack-nerd-font

Coding fonts

Fonts that ideally look good in monospace and make it easy to distinguish similar characters. (My bugbear here is distinguishing different quotes, e.g. "“”). There is a website for this ProgrammingFonts.org, where you can see all the ones of note. Your OS ships with some, maybe Ubuntu Mono or Inconsolata or such. Or you can level up your designerly OCD by using Nerdfonts.com, which distributes cult developer-friendly fonts with extra glyphs for … weird UI icons and such?
