There aren't many articles, but the ones that exist have been crafted with EXTREME attention to detail and DELIGHTFULLY interactive animations. I would recommend the mechanical watch and internal combustion engine posts specifically to start. If you like knowing how things work, this guys blog scratches that itch better than like, anything else I have found for the specific things he makes posts about. Have fun, be prepared to kill a few hours.
I've gotten into the habit of just going into the terminal and using shutoff instead of using the os button for it. It seems to work every time, and I'm on the AMD CPU, Nvidia GPU situation as well. I'm really hoping this getting into bazzite will fix the issues I have with discord on Wayland.
