  • You have to write out a lot of exercises and there is no getting around it. You can’t learn the violin by watching videos or reading a book. You have to practice. It’s the same with math. But as people said, Khan Academy lectures are very good in steering you through a topic.

    Besides algebra, I think it is important to know a bit about probability and a bit about logic. Don’t worry about stuff like covariance matrices, but understand what conditional probability is (be able to explain the “prosecutor’s fallacy”) and write out some of those annoying exercises about urns full of colored balls. Also, show how to write e.g. “you can fool all of the people some of the time, and some of the people all of the time, but you can’t fool all of the people all of the time” in predicate logic notation, and see how the parts of the sentence involve switching the order of quantifiers.






  • Two angry men on separate occasions have made comments to me about masking and how I don’t need to do it. I just stare right through them and ignore,

    I just say thanks, I prefer wearing it and I’m more comfortable with it on. That generally works.

    but why are they so angry?

    Might go back to the conflicting and stupid instructions we got when the pandemic started. The public health establishment lost all its credibility and continues to mess up.











  • They are generally locked down to specific carriers too.

    A 20 year cell phone isn’t happening though. The networks change out too often. I still have perfectly solid 1g, 2g, and 3g phones that are useless because the networks they used are gone. 4g still works but for how long? 5g will be around for a while, but 20 years? Dubious.


  • Browser = excessively smart! And why would it run Android if you can’t other apps on it? My original flip phone only did voice calls. No SMS. That came later. I don’t remember if it even had speed dialing, but it’s still in a drawer someplace, so I might check. 2G phones had voice and SMS but no internet of any sort. No browser, for example. They were great. Some were as small as cigarette lighters. Maybe there are smart watches now that can make phone calls independently though.

    I spent a while searching for a super-dumb phone for the sake of a guy I knew who got hopelessly confused by his Android phone, but it’s now no longer needed.


  • I’m sure analogous situations have come up many times in history, such as in the Roman empire. The Borgia clan in the Italian Renaissance got a possibly unjust reputation for stuff like that. Machiavelli’s “The Prince” was supposedly inspired by Cesare Borgia.

    Part of the answer has been to be careful who you pick as VP. Trump picked Pence partly because Pence (at the time) seemed to have no presidential ambitions. It worked reasonably well, since Pence could have (politically) put the shiv into Trump during either of Trump’s two impeachments. If Trump becomes president again, he’ll likely get impeached at least a couple more times, so we’ll see if Vance is similarly loyal.
