This book is awsome, I spent money on hireing people to make simple network aps for me that far exceeded the 35ish dollars spend on this book. I have yet to come across a book that "teaches" to the new commer. So far ive understood every thing the author has wrote. Im a complete new comer never touched the networking stuff(at least not got anything to work) and ive already created a couple usefull things. Alot of people are upset the source code was not included but personally I dont mind retyping it yourself helps you learn. Again if I could I would rate more stars kudos to the author.
