April 17, 2006 — The recently arrested "boss of bosses" of the Sicilian Mafia, Bernardo Provenzano, wrote notes using an encryption scheme similar to the one used by Julius Caesar more than 2,000 years ago, according to a biography of Italy's most wanted man.
. . .
The letter, written in January 2001 by Angelo Provenzano to his father, was found with other documents when one of Provenzano's men, Nicola La Barbera, was arrested

"...I met 512151522 191212154 and we agreed that we will see each other after the holidays...," said the letter, which included several other cryptograms.

"The Binnu code is nothing new: each number corresponds to a letter of the alphabet. "A" is 4, "B" is 5, "C" is 6 and so on until the letter Z , which corresponds to number 24," wrote Palazzolo and Oliva.

While the classic Caesar cipher moves everything three letters later (A becomes D, B becomes E, etc.), the "Provenzano code" assigns a number to each letter by simply increasing by 3 the value given to the 21 letters of the Italian alphabet listed in order.
So, A becomes 4 (1 3), B becomes 5 (2 3), C becomes 6 (3 3), etc
"In the Provenzano code the key is the 3 shift," mathematics expert Alessandro Martignago told Discovery News.

As the code is cracked, the "512151522 191212154" person becomes "Binnu Riina." Most likely, it refers to Bernardo Riina, arrested on Wednesday on suspicion of aiding Provenzano while he was on the run.

I got a letter from someone who said that Provenzano might have done better if he would have read my book first . . . ;)

Mafia Boss's Encrypted Messages Unraveled

Many years ago (1995, I think), we were brainstorming new game ideas at my office. Under the "no idea is a bad idea" principle, I came up with a suggestion of a massively multiplayer morphing artwork, where each person in the game would be in charge of the color of one pixel, and teams would compete to see who could draw certain images (a bicycle, a house, a face, etc.) the most rapidly. I sort of envisioned it like a cyberspace version of those big sports stadium events where a part of the audience would all hold up cards in sequence, to make a design.

Well, my idea was greeted with near universal derision: "Ha! That sounds totally boring, no one would ever play that," (so much for the spirit of positive-reinforcement brainstorming, heh).

Anyway, my arch-critic from back then recently sent to me this link, of a "pixelfest collaborative artwork". It's not quite the real-time dynamic team-based thing I had in mind, but it's close enough to make me smile. :)

Feel free to add your own pixel!

Update: To see an animation of the 7000-odd pixels that have been placed so far, check here: http://haub.net/pixelfest/ . I found it especially interesting to see how certain people tried to "grief" the image early on with four-letter words, but then the community responded by erasing words as soon as they started recognizing them. Some interesting dynamics there. :)
