  • Knowing that the ball was gold gives you Bayesian knowledge about the boxes behind the door, since the prior probability of the host pulling a gold ball from a 6-gold door is different than from the 3/3 door. So you have to multiply Monty Hall probabilities and Bayesian probabilities together.

    That assumes the host pulled a ball at random, of course, and not a deliberately gold ball.





  • He’s been in the news for several years already. I’ve looked into doing the bounty hunting thing - I couldn’t find anyone in violation! Every truck and bus driver in the city are generally in compliance of the idling limits. Only occasionally would some one-time-visitor out-of-towner who might not be aware of the city ordinance run afoul. Not sure whether people are just respectful of traffic rules, or whether this guy is a menace everyone knows about. If so, the bounty program is working effectively as intended!

    KM3-230213A is an ultra-energetic (220PeV) neutrino event recorded by the Cubic Kilometre Neutrino Telescope (KM3NeT) on the bottom of the Mediterranean sea. The telescope consists of thousands of photomultiplier sensors suspended in the water, watching for Cherenkov radiation of the decay particles resulting from the rare collision of a neutrino with the inside of the Earth. There is no known cosmic mechanism how a neutrino so energetic could have come to be.

    This meme proposes the hijinks of Apu as an alternative explanation of how all those blue-sensitive photomultipliers got activated (saturated even) in a straight line going from bottom up all at once.





  • it’s not clear that he’s following Monty Hall rules

    Whenever I see a badly-specified Monty Hall Problem, I always imagine the host saying something like “Oh, you want to pick door number 1? Well, guess what - the car was behind door number 3 all along! You get nothing but a goat!” And only when you initially pick a door with the car does the host ask “Are you sure you wouldn’t rather switch to door number 2? Look, there is even a goat behind door number 3!” Switching doors 100% gurantees you get a goat… or 50% silver balls in this case.








  • I know Lemmy hates AI, but this actually would be a perfect use for it. The problem is the idea of what an ad is. Yes, you could try to use secondary characteristics like image color or sound normalized volume (WhyTF do youtube ads still sound 3x louder than content? are we living in cable era again?), but they would be error-prone for any content more visually intense than a podcast. They would also not capture sponsorblock content like “I love showing you all these foreign countries but what I love even more is having my internet connection secure” that match the video flow. A crowdsourced lookup table of all known ad clip fingerprints would go a long way, until ad videos themselves start being AI-generated on the fly for that sweet personalization revenue.

    No, what I really want is to distill the idea of what I want to see into an AI and have it filter out what I don’t want to see for me. I know an ad when I see one, so AI can too. Pre-roll/mid-roll ads? Gone. Sponsorblock content? Gone. Like and subscribe? Skipped as if it didn’t exist. Virtual billboards on the sidelines of sporting events? Overlayed with kittens. Idiocracy banners squeezing the video from either side? Cropped and rescaled. Watermarks? Excised and content-aware-filled.

    The last frontier is when the content itself is secretly an ad, imprinting upon you some idea or point of view. You’ll have to watch out for that one on your own.


  • In the ultimate, you’d need to do something like run a headless browser in a virtual machine, have it play out and record the entire video, then use something like AI to splice out the ad segments and distracting elements (a souped-up sponsorblock will work for a while, but eventually ads will be injected into the raw video stream at random intervals), and present the pristine finished content to you. Basically we are going to re-invent TiVo all over again xD.

    In worst case, you can’t start watching until the pre-roll ad timers expire. This is how adblocking works on Twitch streams currently - you can only see a purple screen even if you block the ads.

    And yes, the headless browser will need to use AI for human-like mouse movement and to solve captchas - basically whatever state-of-the-art technologies spammers and scrapers are already currently using.

    Google is anticipating this future and is trying to implement and force hardware-based DRM for web video before then.
