Oh boy, I have fallen behind in posting here and there is no one excuse or reason. I’ve been having recurrent digestive problems since I had salmonella poisoning several years ago. I know that dysentery can recur but I didn’t think that salmonella was quite that serious, although I seem to be doing better this past week.
Then about the time I was getting better, and making progress on my latest book, I got called for jury duty. Jury duty is like being back in junior high school or in the military. I’ll leave it at that.
I was able to resolve the problems of matrix Algebra using J but I’ve only partially succeeded with factoring polynomials. Part of the problem is the clarity and purpose of W. Michael Kelley’s explanations on this topic are not coming through to me, and also that I am having to take concepts from I-APL and translate them into J. I’ll get there, it just seems that I’m having a harder time making the connection.
Unfortunately, we are at a political crossroads right now. Some of our politicians are engaged in serious mischief. But I promised myself that, with so many other talented people writing on this subject, I would stick to other subjects.
Finally, I hope those of you living in the U.S. survived the switch to daylight savings time. People with sleep disorders have a really difficult time dealing with these changes.
So, as the English say: Stay calm, carry on.
