Setup OSX with a Clean Install

About once a year, my machine gets pretty sluggish and it's time to start fresh. Here's the process I use to update it with everything I need.

TODO: Add info about dotfiles set up and zsh (possible settings file?)

1. Start with a Fresh Install of OS X

• Save all dotfiles to a repo for easy transfer
• Back up all photos, music, apps, iTunes library, keychains, etc.

# config/initializers/clear_logs.rb

# This snippet simply clears your logs when they are too large.
# Large logs mean looooong search in TextMate. You know it :)
# Every time you run rails server or rails console it checks log sizes 
# and clears the logs for you if necessary.

if Rails.env.development?
  MAX_LOG_SIZE = 2.megabytes
