  #Problem:
  #In rails 3.0.1+ it is no longer possible to do this anymore;
  #  rescue_from ActionController::RoutingError, :with => :render_not_found
  #
  #The ActionController::RoutingError thrown is not caught by rescue_from.
  #The alternative is to to set a catch-all route to catch all unmatched routes and send them to a method which renders an error
  #As in http://techoctave.com/c7/posts/36-rails-3-0-rescue-from-routing-error-solution

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
