"Manny, you broke the curse on my teeth!" -sign held by the kid who lives in the house where Babe Ruth cursed the Sox by chucking his piano in the lake and who got his teeth broken by a foul ball Manny hit
Can you even believe the Sox made the Series?

I can't, but it makes me happy! Maybe we didn't set ourselves up for a hard fall into disappointment this year!

Too bad it's on one of the channels that doesn't work well on my TV.

Anyway, today, a friend came down to work on our History Day project. We chose the Enigma code breach at Bletchley Park, because the topic is communication and the time limit is 1789 to 1970. Actually, it was pretty cool. (Ever seen the movie U-571? That's the machine in there, though most of the facts about the capture are made up.) Basically, you have this machine that has three rotors in it so that when you type Q, a current will switch it to, say M. Then they do a Caesar cipher, so M becomes K. Then third rotor and current changes K to, say J. Caesar cipher, and J is now L. Then you apply a reflector, and not only dose Q result in L, but L results in Q. It's really complex and techinical, and whenever the Germans figured out the Allies had gotten it, they through in another rotor so the Allies would need another machine. It's also really neat that they had to invent computers for this to process so many possibilities fast enough, because the way it worked is, you set the rotors randomly every time you encode and the only clue you get is that the first letters they type are always ABCDEFG. So, every individual message, you have to figure out how the rotors were set and set them that way and then type back the message as it is encoded to get the decoded version.

Wow, that's complicated, and I'm not even totally sure I get it.

At any rate, 6 or 7 hours later, we have a really nice-looking posterboard.

And I'm so tired, and I need to watch the game.
