One thing from the article I found interesting is that a very detailed spec is equivalent to the program. That is, I found it interesting when I "discovered" it a few years ago. Let's try a little poll: if you found that interesting and already knew it, upvote this comment. If you found it interesting but didn't know it, downvote it. If you didn't find that interesting, don't vote.
