  • That’s always fun. Some people will swear it can’t possibly work like that, but they have plenty of experience riding bikes. You wouldn’t be able to turn properly at speed unless you’re counter-steering, so they clearly have done this. The idea seems to be so incredibly intuitive that people don’t even realize they’re doing it, which is very interesting.


  • The idea behind clips is that you can pull up on the rising pedal instead of just following momentum from the other foot pushing down. It does work, but isn’t really necessary for commuter biking.

    I got a used bike that had a hybrid pedal with a clip on one side and flats on the other. While the clip (heavy) side usually landed down, it didn’t always and it was weird to pedal with it. I just ride around on my bike, so I replaced them with cheap flat pedals and it’s fine. I also converted it to an e-bike, and I don’t need the extra pedal power.


  • It’s pretty common to bring up gyroscopes for this when people know a little bit about physics. It’s all over motorcycle forums, for instance.

    As you say, it doesn’t work. Experiments have been done where they attach a counter rotating wheel to cancel out the gyroscopic effect, and while it’s a little wonky to ride, it works fine.

    IIRC, we’re not 100% sure how bikes work just yet. Every time somebody comes up with a model that seems to be good, someone finds a counterexample that throws it in the bin. Even your explanation of bike trail isn’t all the way there; Razer-type scooters still work without trail on the front wheel.


  • It works on its own. If you push your bike along with a good run and then let go, it’ll stay upright until it slows down too much.

    Learning to ride a bike is mostly about being confident enough to let the bike work itself out. It gets more stable as it goes faster, but it’s natural to be afraid to go faster when it already feels unstable at low speed. Then there’s a little bit to learn about countersteering, but most people figure that out without being told it’s even a thing.




  • You know, maybe we shouldn’t be taking estimation advice from a 1980s science fiction movie that amounts to a systematic method of lying.

    Yes, I’ve used it before. Yes, you can hopefully have everything average out in the end. Yes, project managers demand estimates. None of these are good reasons to back up how fundamentally flawed it is.





  • Harris I think really did catch them off guard. Which is a bit surprising?

    If we were talking about the GOP of 12 years ago, they would have been able to pivot to Harris much more easily.

    Trump ate the brain of the party in an almost literal way. A lot of the people who knew how stuff worked–McCain, Paul Ryan, Dick Cheney, Romney–were all pushed away or were disgusted with Trump. Basically all the smart, Lawful Evil people. This cycle completed itself this past spring/summer, when Trump replaced all the internal GOP committee members with his own people. They were chosen for loyalty first, and competence a distant second.

    That factor of loyalty first/competence later makes fascism fall apart in the long run. However, they can do a whole lot of damage while the failures work themselves out. If we could figure out a way to get them to speedrun this process, we’d have a very effective tool to fight fascism.

    This is what I expect to happen when AI gives solutions to climate change. Which is what Sam Altman bangs on about in interviews to justify all the power AI models are taking up.

    The solutions are all sitting right there. What people actually want is solutions that cost about three fity and don’t require any lifestyle changes. ChatGPT will just tell us about all the solutions sitting there, but that’s not the answer people like Altman want.






  • There’s downsides to the companies, though. Interviewing new candidates takes money, and takes time away from people already on the team. If everyone is switching jobs to get a higher salary, then companies aren’t saving anything in the long run. They also have a major knowledge base walking out the door, and that’s hard to quantify.

    It’s a false savings.

    If I were to steel man this, it’d be cross-pollination. Old employees get set in their ways and tend to put up with the problems. They’ve simply integrated ways to work around problems in their workflow. New people bring in new ideas, and also point out how broken certain things are and then agitate for change.

    This, I think, doesn’t totally sink the idea of the “company man” who sticks around for decades. It means there should be a healthy mix.



  • To steel man HOA’s, they take care of common property in a similar way to condos. Anything from street lights, to the sign at the front of the cul du sac, to the playground that seems oh so much nicer than what the city ever puts in. Some even provide garbage service and maintain the streets. Municipalities have been happy to offload this burden.

    Steel man off: their point is to keep black people out. The superficial niceness is so white people can say how great things work for them, even when they’re only one layoff away from losing it all.
