It seems like every time I’m talking with someone about computers, I keep mentioning two topics. First, I am almost always reminding people to back up their data. Second, I try to explain how important it is to think more about computer security and to act on those thoughts. On the topic of computer security, you could do a lot worse than read the blogs of Brian Krebs and Bruce Schneier. We all live in a civilization more and more dependent on the Internet, so we need to all pay attention to keeping it secure and working.
