If you only read one interview with security and cryptography expert Bruce Schneier today, make it this one hosted by Freakonomics co-author Stephen Dubner, with questions submitted by his blog readers. Loads of great links to posts and articles by Schneier on issues of security, most of which comes down to questions of economics (and why it is on the Freakonomics blog). Just one short quote:
I write my passwords down. There’s this rampant myth that you shouldn’t write your passwords down. My advice is exactly the opposite. We already know how to secure small bits of paper. Write your passwords down on a small bit of paper, and put it with all of your other valuable small bits of paper: in your wallet.
