Done Since 2018-09-30

The program I've been working on, which displays a rotating hypercube or other shape, is working nearly as well as the version I wrote in C about 30 years ago. This version, however, is in Javascript and runs in your browser. It still needs quite a bit of work on the user interface, and there are a couple of really weird things going on with simplexes (simplices? The regular 3-simplex is the tetrahedron; the 2-simplex is the equlateral triangle. Anyway...) follow the link to the current working version.

I've learned a few things:

• quite a bit more Javascript,
• that Javascript, in many ways, sucks even more than I expected,
• that that I can still concentrate on a program all day, every day for a week,
• that I'm still lousy at estimating,
• and that I really shouldn't try to do geometry in my head (though I did pretty well on the perspective transform, I think).

In other news, my trigger thumb is no longer triggering, meaning that the inflamation in the tendon has gone down. There are still quite a few residual aches and pains, probably caused mainly by under-use over the last month or two.

Down in the notes for Tuesday you'll find the practice questions I used with (nephew) j, and under Thursday you'll find a lot of rather inconclusive talk about the alleged Supermicro Hack. It's quite strange. Somebody's credibility is going to go through the floor, but whether it's Bloomberg or Apple+Amazon is not at all clear at the moment.

I really didn't want to be living in a dystopian SF underground comic book, but that's the way things are trending.
