I went .emacs bankrupt this summer.

gist.el, powershell-mode, yaml-mode, org-mode are a few I've taken out for brevity.

Otherwise, a few of these are emacs23 specific:

  ;; syntax highlighting
  (global-font-lock-mode 1)
  
  ;; add .emacs.d to load path
  (setq load-path (cons "~/.emacs.d" load-path))
  
  ;; nethack
  (add-hook 'nethack-mode-hook (lambda () (linum-mode 'nil)))
  (setq load-path (cons "~/.emacs.d/nethack" load-path))
  (autoload 'nethack "nethack" "Play Nethack." t)
  (setq nethack-program "/opt/local/bin/nethack")
  
  ;; 4 spaces in objective-c
  (add-hook 'objc-mode-hook
            (lambda ()
              (setq tab-width nil)
              (setq c-basic-offset 4)))
  
  ;; straight to *scratch* buffer please
  (setq inhibit-splash-screen t)
  
  ;; use old navigation for line movement
  (setq line-move-visual nil)

  ;; linum mode
  (require 'linum)
  (global-linum-mode 1)
  (add-hook 'linum-before-numbering-hook
  	  (lambda () (setq linum-format "%d ")))
