Thursday was not a keeper - definitely a day I should have taken off without dipping my toes in the water. At least the short distance I swam I did quickly, easily staying ahead of Gary (I don't know why I named him that), who usually gets to a mile at the same time I hit 1,200 meters.
Spent the evening working on a version of Jefferson's Wheel Cipher, which is very cool, and also trying out an AppleScript version of the cipher written by my father. Also very cool!
Here, by the way, is a mildly amusing problem set that includes inquiries about how to attack Jefferson's gizmo.
