Since first starting to use a mac I knew that I wanted to keep a single place where I could keep my notes of delightful programs, shortcuts, and other things I might want to remember.
This is made for my own memory only. But I thougt I might as well keep is public, so that others could find it, like I myself often find tips in other peoples Gists.
I do not setup all my settings when I get a new mac. THis is only for my own memory. Most of my settings and programs are either in my .dotfiles or automatically synced though mackup (as part of my .dotfile setup).
I also keep a time machine backup on an SSD connected to the dock in my office, so that if I need to change setups beacuse of an emergency, I do not need to use 3 days to setup all of this stuff.
