The Simon Singh book, “The Code Book”, has arrived. After a long perusal flicking forward and back again through many pages I can’t find anything about adding 1 or subtracting 1. I did however find a chart that helps code and decode the OTP lists. Oh, I got that wrong too. They aren’t called One Off Pads; they are called One Time Pads, OTPs. The coding list/chart is called a Vigenere Square after the cryptologist Blaise de Vigenere. In the square the letters have B as 1, C as 2 etc. and Z is 25, then A is 26. This must have been the source of my plus 1 subtract 1 confusion. So all seems correct as I published previously.

The code breaker breaks down in tears

We went to the cinema today to see Mr Turner. It was about the life of JMW Turner the painter. It seemed to start halfway through his life then onward. He led a mixed up home life and a lot wasn’t stated. He and his father’s housekeeper grew old with him but her true relationship was not explained. She may have been his lover at some point but maybe just the one shag. There wasn’t a story as such but the scenes were beautiful a lot of the time, very visually attractive. Later in life he lives with a widow in Margate but it isn’t stated if they married or not. He treat his real wife and children as though they didn’t exist. Timothy Spall as Turner was masterful and we both enjoyed it but there wasn’t, as I wrote above, a story to relate.
