  • You need to roll two dice to get a sum of seven. Consider two fair dice: No matter what the first dice lands on, there’s a 1/6 probability that the second dice lands on the number you need to get a total of seven.

    Consider now that one dice is weighted such that it always lands on 6. After you’ve thrown this dice, you throw the second dice, which has a 1/6 chance of landing on 1, so the probability of getting seven is still 1/6.

    Of course, the order of the dice being thrown is irrelevant, and the same argument holds no matter how the first dice is weighted. Essentially, the probability of getting seven total is unaffected by the “first” dice, so it’s 1/6 no matter what.



  • I’ll add on that a lot of (most?) modern cars have some kind of “phone home” capability that can likely be tracked. Park well away from your destination, and avoid using public transportation if there’s camera surveillance there.

    Make sure to bring some cash and/or a prepaid card. You never know when you’ll wish you had it.

    A plyboard sign doubles as a shield, a cardboard one does not.

    Consider bringing earplugs and/or headphones in case flashbangs are thrown.



  • Whatever anyone China-affiliated says they’re not doing, it’s a safe bet that’s exactly what they’re doing.

    I’m not going to push any conspiracy theories, but I believe the strongest evidence pointing towards Covid-19 originating in a lab is the Chinese government insisting that it didn’t, while prohibiting anyone not under their control from investigating. That doesn’t mean it did originate from a lab, but if anything, that’s what it points to. To be explicit: My impression is that, currently, most available evidence points towards natural origins. However the Chinese government has done its best to convince me otherwise.




  • To be fair, this was originally the point of plastic. The primary point of plastic today is that it is an extremely cheap material that you can mould into pretty much any shape.

    Need a bag to carry stuff? Plastic.

    Packaging for toothpicks? Plastic.

    Spacers inside an electric circuit? Plastic.

    Packaging for clothes? Plastic.

    Fake plant? Plastic.

    Part of the problem is that we’re using a wonder-material that lasts forever (plastic) for a bunch of mundane shit where we don’t need it, because that wonder-material turns out to be the cheapest material around as well.






  • I’ve used this kind of short-range FM sender in an older car to get Bluetooth capability. Just set it to some available frequency and save the channel as “AUX” or something, then you can switch from the radio to Bluetooth by just switching to that channel. Works like a charm.

    Of course, you’ll have to live with the fact that the car next to you can tune in on the signal, but I’m very rarely in still-standing queues so I’ve never thought twice about it. I believe the range of the sender is like 20 m to a normal car radio.
