  • I think that brain one was from a game of telephone with the real fact that a large portion of our brain is dedicated to image processing and object identification. Another portion would be dedicated to sound recognition with a decent amount of circuitry going into the recognition and parsing of speech. Memory will also take up some of the capacity as well as mapping desired actions to sequences of signals for muscle activation. After all the things our brains need to do just to accomplish all these things we take for granted are accounted for, it doesn’t leave much capacity left over for thought.

    Though, at least in my experience, the most powerful analysis the brain can do is in the subconscious. So many times I’ve faced a difficult problem where I’ve been unable to make any progress, take a break, then later return to a much easier problem. Or even with skill development, try doing something too hard for a bit, then sleep on it and try again the next day and it might suddenly be easier. This works best for dexterity skills, I’ve noticed it a lot in Beat Saber.

    So it’s like you can take whatever was left over from the first paragraph, then take a small amount of that and that’s your conscious thought capacity and the rest is given to subconscious processing.

    Yeah, one that I always think of is the see-saw one where a sky diver’s parachute failed so he aimed for a see-saw with a girl sitting on one end which resulted in the girl launched shot upwards and then landing safely on top of a building.

    Their first test used basically a metal plank on a fulcrum and the forces did more to bend the plank than they did to launch the girl and she didn’t get high enough.

    Their second attempt used a see-saw that was built using suspension bridge tech to essentially make it instructable, resulting in fatal forces from the launch. At this point, they called it busted.

    But I see two unrealistic extremes where reality would exist somewhere in the middle where see-saws are designed to not break easily but not to the point of being indestructible and there might be a sweet spot where the forces are high enough to launch girl several stories up but not high enough that she dies from the forces.

    Also, for the bull in a china shop one, I’m guessing that saying resulted from a bull ending up inside a china shop during a running of the bulls event, where stress would be high and there wouldn’t be an easy and obvious path out on the other side, plus maybe a shopkeeper suddenly trying to get it out in a panic. I think that would get the expected result, especially after a few shelves have broken and each step makes more broken sounds.


  • Car doors that aren’t on teslas don’t fail open, they are reliable enough that I can’t think of hearing about any failures that don’t involve a collision and deforming of the door (in which case it’s a fail closed and they use the jaws of life to get people out, or another door).

    An electronic latch is either engaged or it isn’t. Fail open would mean that in the absence of an electronic signal saying it should be closed, the latch will default to not being engaged, which would mean there’s nothing holding the door closed if another force acts on it.

    Don’t assume any benefit of the doubt about Tesla’s. I made no comment one way or another about what I think of their doors vs other doors. For the record, I agree completely that they fucked up this part of the design. The purpose of my comment was to say that taking that design and adding “fail open” to it won’t fix it. Fail open and fail closed both have problems with an electronic latch and the only way to fix it without causing other big problems is to design it in a way that still functions as a door that can be open or latched closed whether or not the electronic part of the latch is working.

    And I’m “deliberately misinterpreting” what fail open means? I’m having trouble understanding how it can mean anything other than how I’m interpreting it, even with your clarification, given the disagreement about other car doors failing open. Maybe it’s a misnomer that I’m misinterpreting but why are you assuming I’m doing this in bad faith?

    The downvotes themselves don’t matter, I asked because I wanted to know the reasoning behind them, well aware that bringing them up at all will probably result in more of them.



  • For the fail-safe bit, if the latching system fails to an unlatched position, then the inertia of the door itself could cause it to open on braking and turns (or if someone leans on it or bumps it), since nothing else would be holding it in place.

    Obligatory fuck Elon Musk lol.

    It’s not generally as bad here as it is on Reddit. I still see the occasional comments that make me wonder if their author has any reading comprehension skills, but Reddit seemed to have representation from those kinds of posters in most comment threads. Even on the topics where Lemmy has general biases for, comments can still go off the beaten trail without getting crucified.

    Though with the smaller sample size of voters, I think Lemmy might see more cases where a comment initially goes one way and then swings the other way, which seems to be the case with my comment above, at least for now (and is part of the reason why I try to refrain from ever commenting on the votes, but usually there’s also a spicy or bolder part of my comment where I’m not as surprised if it goes negative).
