Thanks man! Looks interesting. actually there's been a lack of spreading ruby's knowledge.

Many thanks for this. Very generous of you.

Thanks for creating this

This is one of the best Ruby books I've ever read. I like your DGAF attitude where you get straight to the point and aren't afraid to give opinions.

It's a shame that this post didn't get upvoted more.
