  • Here is something I remember from 2 decades ago.

    https://www.npr.org/2004/04/28/1861434/ben-jerrys-uses-sound-to-chill-ice-cream

    They used sound to make standing waves that created areas of hot and cold, then somehow ejected the hot, keeping the cold. You’d just keep the hot and eject the cold instead.

    Unless you are going to do something like Ben and Jerry’s though, all you are going to be doing with your speaker idea, as far as I can see, is to try to induce friction heat via vibration, and possibly move air around. There are easier ways to make heat than that. You may also create mechanical fatigue in the material moving it back and forth so much in the attempt to make heat, which may negatively impact the performance of the material.

    As for ultrasonic humidifiers, they work by exploiting water’s ability to cavitate, as it is a liquid. If you can get plastic to cavitate somehow and emit only water vapor, without destroying the filament, that would be impressive!

    A resistive heater is probably going to be a more effective means of drying filament. Personally I would just get an air fryer and run it in dehydrate mode, if I wanted to use a consumer device in an alternate manner


  • If you think that’s bad, imagine for a moment that they are the only money in the whole system, then charge interest on the loans, and then fast forward to a time when all the loans resolve and everyone is paid back. It’s actually impossible, because there’s not enough money in the whole system to both pay back the loans and charge interest. You have to print money to make the system keep working, but doing so devalues the currency. To cover the loss of value, prices go up to compensate (inflation).




  • This is going to be a super weird request for a handful of reasons, the first being that you already abandoned watching it, but for some reason I am just super curious what your review in particular would be if you watched the whole thing, just for the sake of it now that you’ve said that, and came back to tell us. Other reviews be damned, something about your reaction to it is interesting for some reason, which makes your opinion of it in full compelling, if you’d consider humoring us. I’m serious.


  • If you thoroughly enjoyed the show, you will be tickled by The Good Place: The Podcast. Mark Evan Jackson (Shawn) hosts it, and it’s truly excellent. Lots of behind-the-scenes info from people who are truly dedicated to their craft. If you thought the characters were great, the people and writers behind them are even cooler, and you get to hear so much neat stuff about the show from them.

    Michael Schur also wrote (an often hilarious) book called How to Be Perfect, about what he learned about philosophy from the research he did in order to write the show. If you get the audiobook version, parts are narrated by some of the actors from the show, and it’s just a delight as a fan. I don’t think anyone would become a philosophy expert from the book, but it’s an introduction to it, and amusing to boot. A good book IMO.












  • When a former employer sent me on business trips, the bean counters would complain that my descriptions for the purpose of meals on my expenses were not descriptive enough, as if the purpose of eating was not obvious. I ended up writing something like “nourishment to remain alive while traveling for XYZ project” out of frustration after that. That did the trick and shut them up. I suppose it was hard to argue that description, because if they disputed it, they’d basically be admitting they were sending me away because they wanted me to die.
