Turn off annoying window reopening in macosx after reboot (persistent)
# create a clean reboot without the windows you don't want to have
# by rebooting your mac (uncheck the reopen windows checkbox in the reboot dialog
# take over this file
sudo chown root ~/Library/Preferences/ByHost/com.apple.loginwindow*
# and prevent further changes (checkbox in reboot dialog doesn't matter)
sudo chmod 000 ~/Library/Preferences/ByHost/com.apple.loginwindow*
# to undo it, simply delete the file. It will be recreated automatically

Start Emacs Client in GUI (and launch Emacs server if not already running)
#!/usr/bin/env bash
# Shamelessly taken from http://mjwall.com/blog/2013/10/04/how-i-use-emacs/
# This script starts emacs daemon if it is not running, opens whatever file
# you pass in and changes the focus to emacs. Without any arguments, it just
# opens the current buffer or *scratch* if nothing else is open. The following
# example will open ~/.bashrc
# ec ~/.bashrc
