Thursday, February 5th, 2015 12:42 amWhy did I have to spend the last 2 or 3 hours reading about how the German Enigma encryption machines worked, and how the messages were deciphered? Why doesn't the part of my brain which is engrossed in something like that ever pay attention to the other part of my brain that is saying I better stop and get ready for bed?
