Free Book - Ruby Is For Fun by Roman Pushkin

I wrote this book for my son. He is only 8, and hopefully he'll enjoy it soon.It was for sale, but now it's free and under CC license. I decided to share the knowledge, and make the book even better with your help (see how to contribute below).I tried to make things super easy to understand, at the same time emphasize important concepts (like memory pointers, and working with objects). Please enjoy and share :).
