    Self driving cars will allways use far more energy and space per passenger than a train or light rail. And personally owned cars will spend more than 90% of their time just standing around, being useless and wasting space. If you propose self driving taxis, you’re just another step closer to trains.


  • Yes, and “alive” is quite stretching it. Even if Norris wins every point still available in the last 3 race weekends, Verstappen only needs 24 points to secure the title. He could finish 6th three times to secure the title. Even if Verstappen doesn’t get a single point in the last races, Norris needs to finish second every race and sprint and then get at least two more points through fastest laps or a win. There is still some mathematical chance but in reality over.




  • That’s the beauty about open source: it isn’t beholden to the whims of anyone. If disagree with the Linux Foundation, you’re free to make your own independent fork. Others that agree with you can then start contributing to the fork. And this isn’t a purely theoretical scenario as it has happend with other open source projects before.









  • What in this article had you jump to the conclusion that he wanted to chop his penis off? Dysphoria is a thing, no questions about that, but the vast majority of men don’t want their penis removed and from the article it doesn’t seem this man is an exception.

    First of all, self mutilation is a known phenomenon of psychotic episodes. While this is the first documented case of penile amputation that’s also the reason the case study was conducted and we’re reading about it at all.

    Next, he has years of depression in his past. For a depression do be diagnosed he has to be under some form of psychological care. While no guarantee that greatly improves the change of dysphoria being diagnosed, especially if it were severe enough to resort to self amputation with an axe.

    Ultimately, once he came to his senses he did everything in his power to save his penis. If it was his great plan to amputate his penis while making it look like a drug-fueled accident or even if just wanted it removed but couldn’t do so while sober, why would he put it on ice? Shouldn’t he be glad or relieved it’s gone? If he was dysphoric, I would expect him to make sure it doesn’t get to the hospital with him.

    Everything here implies that he didn’t want to mutilate or amputate his penis and in that case implying it was intentional quite insulting, too.

    To escape a body of mass you need to have enogh velocity (kinetic energy) to overcome the gravitational pull of that body. You can imagine it like a ball sitting in a bowl. With little velocity it will just roll back and forth but if it’s fast enough it can roll out of the bowl and escape it’s influence.

    That critical speed is called “escape velocity” and it depends on mass and distance from a body. The escape velocity of earth (from the surface) is about 11.2 km/s and the sun’s escape velocity (from earth orbit) is about 42.1 km/s. Earth orbits around the sun at about 29.8 km/s. If you launch in the direction of Earth’s orbit, you will orbit the sun already at about 41 km/s, so you “only” need 1.1 km/s more to escape the sun, too.

    If you tried to reach the sun, you could launch in the opposite direction leaving you orbiting the sun at about 18.6 km/s. Since there is almost nothing in space you won’t slow down from friction and the orbit won’t decay. Instead you’d have to accelerate opposite the direction you’re traveling. Now, calculating exactly how much you’d need to decelerate isn’t trivial since you don’t want a stable orbit but an elliptical orbit that just touches the sun at the closest point (perihel). I don’t know how much deceleration that takes, but it’s propable that it’s easier than accelerating by 1.1 km/s to escape the sun.
