Without any introduction or discussion, here are the notes I made while learning how to get HTTPS working with Nginx. These are just for me, but if something helps you, cool.
Ubuntu is running great on my old 2008 iMac, but if you’re having Linux performance issues, here’s an ArchLinux page titled “Improving performance.”
This is a link to an article titled, “Optimizing Linux for slow computers.” Note that this article links to this more thorough resource on archlinux.org.

First, here’s the Notes screen. A note can be anything with a title, and optional body:
