To echo everyone; Hackers is a great book. Steven Levy books are both compelling reads and content rich. Crypto and In the plex both have their place as well. http://www.amazon.ca/s/ref=dp_byline_sr_book_1?ie=UTF8&field... I would also say "The Information" by James Gleick. It is a page turner with some neat concepts. Which is not so easy to do. http://www.amazon.ca/Information-History-Theory-Flood/dp/140...
