I'm trying to take as much of my necessities and work into Emacs, because it's the best operating system, by coincidence having a decent text editor. And, although it's an enslaved lisp machine, it's, unfortunately, the best of what we have now.
I had home-grown package-management functions before I moved to use-package. Now I don't. Most of the code is either copy-pasted or inspired by the work of others. Some pieces of copy-paste even have the links to the original habitat of the borrowed code.
Also, because Guix provides me with the environment command, I'm thinking of splitting the config file into several ones -- for coding, academic work and daily tasks, for example.
