Query: Brilliant for the UNIX Geeks

Takedown was one of the first books that I read about Cyber criminals. Shimomura's prose is brilliant, specially for a technical person specializing in Computer security. For all those Die-Hard Unix geeks, this should be a revealition about the bugs in the Unix OS and how the hacker exploits the same to invade. The good thing about the book is the way Shimomura explains some of the Unix concepts to people who are not familier with the Technical jargon.There is also a romantic angle added to the book in the form of Julia, Shimomura's girlfriend.All said and done, this is a good read and a must for all computer geeks. Pick it up NOW.
