I just finished re-reading The Code Book by Simon Singh. I had forgotten how much fun it was going over some of the various facets of codes. I first did so because of research for The Outlaw, which employed a couple of trivial codes.

Singh’s book is great for that, and his website offers even more. On that site, you can actually download a CD-ROM that contains, amongst a wealth of other information, a working Enigma emulator (as in the machine used for German codes during WWII). It’s actually designed to go with the book, but you can learn a lot from the CD-ROM itself. And it’s free, if you download it.

In any case, I won’t bug anyone by posting anything in code now. In truth, since I’ve been working on some of the examples on the CD-ROM for the past couple of hours, my brain is now mush and there’s no way that I’d be able to come up with a decent one to pester you guys with :-P

Still, I highly recommend the book, if you have any interest at all in codes. It’s well worth your time!
