# Simple bijective function
#   Basically encodes any integer into a base(n) string,
#     where n is ALPHABET.length.
#   Based on pseudocode from http://stackoverflow.com/questions/742013/how-to-code-a-url-shortener/742047#742047

ALPHABET =
  "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".split(//)
  # make your own alphabet using:
  # (('a'..'z').to_a + ('A'..'Z').to_a + (0..9).to_a).shuffle.join

 You are trying to install in deployment mode after changing
 your Gemfile. Run `bundle install` elsewhere and add the
 updated Gemfile.lock to version control.
  
 You have deleted from the Gemfile:
 * guard-pow
 * rb-fsevent
