I have been doing ordinary things lately, but working on this blog has not been one of them. Ordinary things have included fixing a garage door, cutting down a tree, buying a car, harvesting two hundred pounds of grapes, figuring out what to do with them, and getting a new roof. You would not believe that such things would keep me so busy for over a month, but they did. My mind seems more ready for heuristics than analysis. Konstantinos V. Katsikopoulos has written many interesting papers, but somehow I have not included them before. This paper takes a little different look at a familiar topic.
