  • I mean not necessarily. Road bikes pretty much never have any actual suspension, all the comfort comes from tire and frame flex. This bike has some fairly chunky tires on, and the way the seat post is just suspended off the back I’ll bet that frame flexes a ton.

    That being said, you’d still have to fine tune the design, and get the right amount of flex in the right ways. I kinda doubt anyone choosing to make a bike like this would have the competency to do that



  • According to that article, this only covers donations to other organizations who then distribute the donated food. It doesn’t cover anyone directly donating food to individuals.

    So for a restaurant, they would need to donate food to a food bank or something, and that would mean food that isn’t immediately going bad. And if that’s the case they’re probably just going to keep it and try to use it later. If they want to donate the leftover food at the end of the day they can’t use anymore, there probably isn’t any time left other than to just give it to some homeless people outside the restaurant, which this act doesn’t protect against.

    Which then just raises the question for me, why isn’t this also protected against? The act already states that the food has to be seemingly good condition, so you can’t just serve mold and say it was a gift. What’s the harm in feeding homeless people?


  • This is not an American invention, nor is it interchangeable with a roundabout.

    The main priority of roundabouts is safe traffic flow for cars, but they can (sometimes) still be very hostile to pedestrians. This type of intersection is meant to prioritize pedestrians as much as possible. The narrow street slows vehicles, and the sidewalk bump outs make people trying to cross the street extra visible and minimize the time they need to be vulnerable in the middle of the road.

    Which isn’t to say that roundabouts are necessarily bad, they just serve different purposes


  • This is potentially more specific to the US, but I imagine even if that is the case it probably affects everyone else by proxy at a minimum.

    One of the big problems with trucks and SUVs is that they are not subjected to the same safety regulations as cars. They have high ground clearances, high noses, stiff suspensions and frames, and so on, and these things make them extraordinarily dangerous in a collision. That being said though, they might be necessary in very specific circumstances, for example if you are going off road and/or towing very heavy loads. If this applies to you regularly, like for work, buy a truck and drive it in good conscience. It is a tool fit for your purpose.

    But if you are like most people, you don’t regularly tow heavy loads for work, and you don’t regularly drive off road, but maybe you do need to carry around lots of stuff and/or people, and spacious van might be more suitable. And with that comes a softer suspension, lower ground clearance, and a sloped nose that will make the van much less likely to kill people in a collision

  • From a physics perspective, yes it does. Not much, but yes it does do something.

    In order for a crumple zone to work, the material must be at least slightly softer than the rest of the structure. When you have a collision, both the strong structure and the relatively weak crumple zones will flex, but the crumple zones will flex more. In a big collision, like with another car, they might flex so much they have permanent damage (the crumple), but even with a pedestrian they will flex a little. The more they flex, the more it cushions the impact for both the pedestrian and the occupants of the car.

    As I said, the amount of cushion for the two parties is massively skewed in favor of the car, and crumple zones alone are not anywhere near enough to make cars safe for pedestrians. But objectively, yes they do slightly cushion the impact for a pedestrian, and in the perfect edge case collision it might mean the difference between life and death.












  • I want to preface this by saying that while I have done some undergraduate work in this area, I am by no means an expert on this topic. If I’m wrong or missing some context, hopefully someone with more knowledge than me can comment and correct me.

    This doesn’t really seem like much to me. The major quantum threat is Shor’s algorithm, which gives an attacker with access to a sufficiently powerful quantum computer the ability to easily solve the discrete log problem. This new protocol still relies on the discrete log problem, and is therefore still vulnerable to the same threat. I don’t understand everything in the paper, but from what I can tell I think they just made DH a little more robust in general, rather than actually providing a long-term quantum solution.
