I appreciate the feedback, especially when it is constructive criticism. It helps me understand how other people were interpreting the post. Perhaps I got the positioning slightly wrong as I wanted it to be more about teaching the basic math and how to translate that into Ruby. I will try and get the positioning better next time. While we do some stats in Ruby it definitely doesn't represent the entire "this is how we solved it". In fact we use a large amount of R and Java to solve all our statistics problems.
