How to create small, unique tokens in Ruby

That is is basically a "fork" of blog article i'm constantly returning to. It seems that the blog is down:

• Original article
• Internet Archives

My choice: Dave Bass’s rand().to_s() trick

Dave Bass proposed this which I picked up for my implementation (here for an 8-chars token):

tallclouds

#!/usr/bin/env ruby

# You should run `gem install httparty` first

require 'httparty'

def comma_numbers(number, delimiter = ',')
  number.to_s.reverse.gsub(%r{([0-9]{3}(?=([0-9])))}, "\\1#{delimiter}").reverse
end
