  • This would only be in ambiguous situations when the confidence level of “pedestrian” and “cyclist” are close to each other. If there’s an object with 20% confidence level that it’s a pedestrian, it’s probably not. But we’re talking about the situation when you have to decide whether to yield or not, which isn’t really safety critical.

    The car should avoid any collisions with any object regardless of whether it’s a pedestrian, cyclist, cat, box, fallen tree or any other object, moving or not.



  • Training self driving cars that way would be irresponsible, because it would behave unpredictably and could be really dangerous. In reality, self driving cars use AI for only some tasks for which it is really good at like object recognition (e.g. recognizing traffic signs, pedestrians and other vehicles). The car uses all this data to build a map of its surroundings and tries to predict what the other participants are going to do. Then, it decides whether it’s safe to move the vehicle, and the path it should take. All these things can be done algorithmically, AI is only necessary for object recognition.

    In cases such as this, just follow the money to find the incentives. Waymo wants to maximize their profits. This means maximizing how many customers they can serve as well as minimizing driving time to save on gas. How do you do that? Program their cars to be a bit more aggressive: don’t stop on yellow, don’t stop at crosswalks except to avoid a collision, drive slightly over the speed limit. And of course, lobby the shit out of every politician to pass laws allowing them to get away with breaking these rules.




  • The difference between 2nd and 3rd candidates is 2000 votes. There were 9 million votes in total. That’s insanely close. There is widespread fear that during the recount some votes will be nullified, and some will be changed in some god forsaken villages, resulting in an overturn (which will result in a re-election according to the constitution).

    Candidate #1 is a pro russian fascist. #2 is progressive pro-european. #3 is just very corrupt and made a lot of people angry. If #1 goes against #2 in the second round, #2 has a decent chance of winning. #1 against #3 would be really bad, like having to choose between hitler and trump.








  • The tape head is basically a small and really sensitive electromagnet. Magnetized tape creates small disturbances in the magnetic signal. Amplify those disturbances and you get sound. Similar to an antenna, but only works in close proximity.

    This also works in reverse. Feed an audio signal through the electromagnet, and the electromagnet will create the disturbances in whatever is next to it. You can do this to record to a tape, or you can do this to pass sound to another tape head, which is how these aux cassettes work.

    You can build one yourself really easily. Just take the tape head from a broken player and solder to an aux cable. Take a cassette, remove the tape, and put the tape head in the middle portion so it comes into contact with the player tape head.
