In my Emacs initialization, I run through a few functions that automatically set up my windows and environment. This `setup-windows` function is unique for each machine that I work on, but I bind it to <F6>, so that I can easily start this. Why yes, if I run this function, I rebind it.

.emacs

(defun setup-windows ()
  "Setup my entire Emacs environment. Function is often called when I first start it up."
  (interactive)
  (frame-fullscreen)
  (split-window-horizontally 168)  ;; On this machine, I know how big
  (split-window-horizontally 84)   ;; my monitor is, so ...
  (other-window 2)
  (split-window-vertically)
  (circe-connect-all)              ;; Connect to all my IRC channels
  (twit)                           ;; Start twitter in this window
  (other-window 2)
  (find-file "~/technical/personal.org")
  (calendar)

  ;; <F6> is bound to this function, but once it starts, I don't want
  ;; to waste such a good keybinding, so I rebind it to the reconnect
  ;; function, which I need to do if the computer goes to sleep.
  (global-set-key (kbd "<f6>") 'reconnect))

(defun frame-fullscreen ()
  "Set the frame window to cover the full screen."
  (interactive)
  (set-frame-parameter nil 'fullscreen 'fullboth))
