Learning Ruby with PickAxe (2)

Any time you go to see the doctor, I am sure you hated the wait. Yesterday was different for me.
I did not mind the wait - in fact, I hoped the doctor would show up a little late. I was having too much
fun - reading Pickaxe 2 (as the book Programming Ruby 2nd edition is called). If you have not read it,
I strongly recommend it. The way Ruby is introduced in the book is very nice. I generally don't learn
programming by reading a book.  But the neat thing is the book motivated me to spend good amount

book. I am approaching it from the point of view of, "here is how this works in C++/Java/C#/VB.NET, how
does it work in Ruby." Of course, there are some things that are different in Ruby compared to languages
I am familiar with. The book has wet my appetite to explore these further...
