# Emacs

## General things

I learned a lot about emacs from the following sites

## My own init.el

See My emacs repo.

I only use org-mode, latex, python, and git (and sometimes plain txt). I think I optimized my init.el for this, and I stripped all the rest.

I decided to not tinker with the standard emacs key bindings; over the years I have noticed that they are mostly very well thought-out, and, perhaps more importantly, they don’t change.

# Optimization and Constraint Programming

A search on python constraint programming yields also many useful links to tutorials and documentaion.
