emacs init.el file

    There are many opinions about the editor to use. Personally, I am not very picky, but I agree with Pragmatic Programmer that as a programmer that will write a lot of code it is worthwhile to become really proficient with an editor. Here my choice is emacs, powerful, flexible, and can be used also remotely in a terminal.

    Emacs is very configurable, my current .emacs.d/init.el changed with time emacs grew and keeping it up to date things I do not actively use is not worth it, for example lost the Fortran and Haskell settings I had, now it is:
