Need people to give feedback

Hello All,

I am porting my Ruby book to HTML here , I would be very happy if people who want to learn Ruby can use it and give me feedback, possibly negative ones so that I can improve my book.

It looks very well produced to me! Congrats. My only criticism is that in practice, that tabbing/indenting of code of more than one space (as in the spacebar) causes confusion when working in collaboration with others. I get frustrated when working on multi-developer projects and some use tabs, double spaces, and single spaces… or even 4 spaces! Messes up the codebase, but I understand where you use it here for readability.


Great, how about a chapter on testing [writing test cases with mini test or rspec? ] and debugging rails apps?
