# software bug to be fixed

The word processor still doesn’t reliably give a bit of a margin at the bottom of the screen. Sometimes the line I’m typing is buried about 5 percent below the screen.

# wanted software feature

the ability to disable the ‘page up’ and ‘page down’ keys.

I never use them, but occasionally accidentally press them, causing a few moments of confusion in getting back on track.

# from ‘labor mobility’ to ‘a gig economy’

Back in the day, one spoke of ‘labor mobility’. Nowadays one speaks of ‘a gig economy’. Has anything really changed?

“The more things change, the more they remain the same.”

Partitions give us a grip on a process. We then obtain answers by doing a living recombination of a partition. By a ‘living’ recombination is meant one allowing the partition valuation to vary. For example, we can partition distance of travel into rate times time: D = RT. Since R = D/T, we have D = (D/T)T, but (D/T) is speed, which can vary. The living recombination is called ‘integration’, and integrating speed over time gives distance of travel. For example, traveling at a constant speed of 20 kilometers per hour for 3 hours gives a distance of travel of 60 kilometers. Significantly, if the speed over the 3 hours is not constant, but has an average of 20 kilometers per hour, the distance of travel is the same as before: 60 kilometers. In general, the distance of travel is the area under the speed curve, between the two points in time under consideration.
