I am very grateful to Mr. RajKumar Sharma of Ahmedabad, India to have
pointed out lot of typo corrections in "I Love Ruby". I have fixed them
and released the book here https://mindaslab.github.io/I-Love-Ruby/
He in a mail claims that he could read this book in 28 hours! I still can't stop wondering how he did it. You can read his comments here https://mindaslab.github.io/I-Love-Ruby/what_people_say.html
I once again thank the Ruby community to have given encouragement which has kept this book alive.
