This is very unclean and unorganized. I've taken a lot of this from other places and people. Organizing it would take too much time. This is a link dump for my personal use only. :)
I find traditional link dump repos organization to require a lot of effort to set up. So I'm trying out a simpler tag-based structure. CTRL+F for the tags you want to read about. I'll be updating the tags slowly but surely.
