Commodity software

 I speed up* my software development work by keeping an AI code library which includes many of my own programs plus commodity software like RobotBASIC and its examples, ROS, various bookcode, code from and for LEGO, VEX, arduinos, raspberry pis, micro:bits, from repositories like GitHub, etc.

* I am less sure how this impacts code quality. It probably depends upon the source.

The unvaccinated

 If the republicans make themselves sick it serves them right. But they're going to make the rest of us sick along with them. (See my blog of 22 April 2020.)

Rating the US presidents

 Again, values are vector quantities. The 10 measures the C-SPAN survey used:

Public Persuasion, Crisis Leadership, Economic Management, Moral Authority, International Relations, Administrative Skills, Relations with Congress, Vision/Setting Agenda, Pursued Equal Justice for All, and Performance in Context

should be considered components of a vector. They can not be combined into some single scalar. Crazy Donald would rank very high in Public Persuasion. He has convinced a great many people to believe complete nonsense. On Moral Authority, on the other hand, he may well rank dead last. In no way do these components somehow cancel or average one another out.

UFOs

Over the years I've seen several UFOs. About 30 years ago I saw a sphere pretty much directly over Emporia. It was still there as I got home so I was able to get out binoculars. I could not keep them steady on the object but it looked perfectly spherical and with two tiny spheres attached to it one on each side at its equator. The next day the press reported it was a research balloon. No details at all were given. Having launched several research balloons myself I only thought that the shape was not what one would have expected.

In fall of 2020 driving to work in the early morning (just before dawn) on highway 35 I saw a silver square or diamond* over the road ahead of me. I considered pulling over to photograph it with my iPhone but I saw I was almost at my exit (Merchant street). While turning and driving I could not keep it in sight but had some hope I could see it again from my parking lot outside science hall. (only a couple blocks on from the exit.) Unfortunately when I parked it was either gone or behind buildings. Could it have been an aluminized mylar toy balloon? Or a drone? I found nothing in the press.

I had a third sighting perhaps 15 years ago. It was almost the same as my recent highway 35 sighting except that all I saw was a light (or small sphere?) in the sky up ahead. I couldn't make out any detail. Could it have been a child's toy balloon?

* One corner pointed straight up and the opposite corner straight down. There was a (inverted) v shaped cut out of the bottom corner of the square. It looked like two square sheets one on top of the other and not quite in  alignment at the bottom. Perhaps hung from a balloon? But very flat and the balloon could not be seen. It was silver and did not seem to move. The weather was calm.
