I think for HN it's worth noting, perhaps in the title, that this article is written by Bruce Schneier.
"Bruce Schneier an American cryptographer, computer security specialist, and writer. He is the author of several books on general security topics, computer security and cryptography."
Update: I said "terrible book" but I'm going to start being more precise about this. It's not a terrible "book"; I enjoyed the hell out of it when I was a teenager. It's just misleading and dangerous.
