Query: Not Worth the Shipping Cost

This book is misleading from it's title to it's content. One would think that the terms introduced would be little known except for int the hacker world but no!! These terms were copy and pasted from some third-party source and I care not to mention it. Don't waste your money on such worthless trash. The two people who gave this crap a 5-star review are probably affiliated with the author.
