+* The init.el file
+** Package matters
+
+I use package from both stable and bleeding-edge Melpa.

+** Backups
+Emacs tends to clutter the filesystem with backup files. A backup file is normally the filename with a =~= suffix. I rather have my filesystem clean, and centralize all backups in a single directory.
+
+#+begin_src emacs-lisp :tangle "init.el"

+    (setq backup-directory-alist '(("." . "~/.backup")))

+#+end_src
+** Customizations
+Customizations don't place nicely with version control, so I do them in a random file that won't get persisted.

+Configurations that need persisting will be added to =custom-set-variables= and =custom-set-faces=.

+** Emacs server
+I used to run Emacs as a systemd daemon, but it was not too deterministic as sometimes it would break.

+
+Now, I simply start it from Emacs itself. This approach works well for me.
