On systemes GPS

Yes, it's amazing how many similarities there are between The Digital Fortress by Dan Brown and his later art and occult secret type books such as Angels and Demons, The DaVinci Code and the latest one set in Washington DC. And I have to admire his research, though I'm not sure how much of what he wrote about the NSA is accurate. Finding a good book on codes and code-breaking with computers in the modern era would have been enough for some of it. But he wrote about the NSA having a secret computer to break all encrypted files and emails. That's more complicated than back then even systèmes GPS were, before they were as common as they are now. And it's hard to say whether he's in favor of online privacy or believes the NSA really is protecting us, especially given the book was written before September 11.
