Query: Waste Your Money and Learn Very Little

I returned this book three days after buying it, it was so bad. It is riddled with computing errors, typos and really terrible writing. The few useful things in the book can be _easily_ picked up off the web for free. The author seems to be a Johnnie-Come-Lately to hacking, has no in-depth knowledge and is just trying to make a buck. This is not a good book even for newbies.
