RESOLVE SHORT URLS before storing. Short URLs are for microblogging; you should never actually keep them around.
require 'net/http'
# WARNING do not use this; it works but is very limited
def resolve url
res = Net::HTTP.get_response URI(url)
if res.code == '301' then res['location']
else url.to_s
end

This Rack middleware for Rails3 lets you see a call-trace of the lines of ruby code in your application invoked during a single request. Only code within your app is considered (i.e. in the /app folder). This expands on my previous attempt (https://gist.github.com/3077744). Example of output in comments below.
require 'singleton'
# outputs a colored call-trace graph to the Rails logger of the lines of ruby code
# invoked during a single request.
#
# Example:
#
# 1) Make sure this file is loaded in an initializer
#
# 2) Add the following to your application.rb in Rails3:
