I read this book in the internet.
I do'nt have paper copy of this book.
I havent found any place in Whil's site where to download code samples of this book.

I expected that if the book is available for a free then code samples should be also available.

I honestly don't know if the source code samples are available or not for free - but I do know the book, and the book is very good, and has many examples and snippets. You're getting large value for free - perhaps more value than you realize.

If you're complaining about the source code not being available, then I don't think you've fully taken advantage of the content of the book itself. You may want to go back and look at the book again.
