  • 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.



  • That looks interetsting but they won’t ship it to the US and it’s unclear if it works with US carriers. I see some similar ones on amazon.com that might be worth looking into, though they are on the expensive side and most have unrecognizeable brands that make me a bit queasy. No-name 2G GSM phones were often below $20, and some were tiny.

    Anyway thanks, that was valid answer. I had mostly looked at Nokia and similar models that had Facebook and stuff like that.



  • There is basically no such thing as a working dumb mobile phone any more. All the old 2G and 3G ones are now bricked because the networks all cut over to 4G/5G. Otherwise what can I say, just avoid stuff with connectivity when you can help it. Also buy corded tools and appliances unless the convenience advantage of cordless is too great to do without. Otherwise you stuck trying to replace overpriced and sometimes hard to find batteries.

    If something is completely FOSS then the software angle is less of a pain in my opinion. I’m still using a beat-up Thinkpad X220 that was made in 2011, but running Debian Bullseye on it. I’ll update it to Bookworm or Trixie when I get around to it. Point is that I can do that, while any phone from 2011 is a hopeless dinosaur.
