20NOV2022 – OCF Update – This’N’That – Of Mice and Math

Sunday, the day of rest.  A good day to regroup and sets things in order for the upcoming week.  Especially this week.  Had a blast with the old grandsons yesterday.  Fun outing, good food.  Got home and skipped dinner.  Skipped all food and drink and maybe that was a mistake.  I was still recovering from that virus that was in the house the last couple of weeks.  But I figured I could skip the cold meds.  Big mistake!  Woke up at 4:30 am with a splitting sinus headache.  So, I beat a hasty retreat to the cold medicine and then sat up for a half hour to let it knock down my sinus inflammation.

But today I’m definitely on the mend.  So, I spent time working on minutia.  I’ve been using the Logitech M570 Wireless Trackball Mouse as my pointing device for the last six or so years.  It’s a great device in most ways.  But unfortunately, the switches for the left and right click buttons give out after a couple of years.  So now I have three of these things that double click when they shouldn’t.  I finally looked into the problem and found a YouTube video that shows how to replace the microswitches and eliminate the problem.  Now I’ll have to buy a soldering iron and some other bits of gear and become a technician.  Well, that’s kind of fun.  Plus, I’ll fix the other two mice and become mouse anti-fragile for the foreseeable future.  Yeah me.

The other thing today was about was to delve into vector analysis.  I never had the time back in the day to play around with the more advanced theorems to get a solid handle on the tensor notation.  In the past I’ve been exposed (as if to a disease) to Del Notation, Dyadics, the Laplacian and equally complex concepts.  The Kronecker delta and how to expand the determinant was something I had to memorize in order to solve some problems in physics.  But if I’m being honest there was very little comprehension on my part at the time as to how these manipulations made sense.  Now I’ve got some time I think I’ll take another whack at it.  The question as to whether I still have sufficient brain cells to thread my way around it and whether those brain cells can retain it remains to be seen.  But it might be fun.

So, amid my other occupations I’ve added electronic technician and math student.  That should make Thanksgiving week an interesting time.  Maybe I’ll buy the microswitches and soldering iron on Black Friday and get some huge discount.  I’ll probably also have to buy some kind of giant magnifying glass on a flexible arm just to see the attachment points for the switches.  It’s a pity I can’t purchase new eyes too.  But once again, the future we were promised all those years ago before Blade Runner hasn’t quite materialized yet.  Well, no need to get all whiny about it.  Magnifying glass works too.

So here we go into Thanksgiving Week.  Turkey, gravy, stuffing, pumpkin pie, old movies and family.  What’s better than that?
