  • The thing I said I did? Yes; here’s the processed image:

    If you mean the math in the post, I can’t read it in this picture but it’s probably just some boring body-of-rotation-related integrals, so basically the same thing as I did but breaking apart the vase’s visible shape into analytically simple parts, whereas I got the shape from the image directly.


  • This roughly checks out. I’m getting 66%, based on the methodology of cutting out the jug’s shape from the picture and numerically integrating the filled and empty volume (e.g. if a row is d pixels wide, it contributes d^2 to the volume, either filled or empty depending on whether it’s above or below the water level).



  • I wouldn’t generally require people to “compile their findings into a report”, but in this case the messages are weirdly devoid of any checkable information and then the reddit user in question mysteriously lost a laptop full of findings, so, yeah, these claims are not compelling. I don’t think the reverse engineer in question was lying, per se, but I do think they were very wrong at first by random chance, the story gained traction, and then they were too embarrassed to admit they fucked up.

    Sort of true, but the algorithm that Reddit-like platforms use is transparent and simple (it’s just based on likes and dislikes, and I think you can even look up the source for the sorting modes) and hence doesn’t directly try to feed you content that’d enrage you. I can just not read the posts about Musk and Trump, since I find most takes on the former bad and don’t care much about the latter. Meanwhile, on platforms like Twitter or Tiktok you are directly fed content out of some recommendation ML model trained on user engagement.

    (There’s also subtler differences. For example, on Reddit/Lemmy/etc, if you hate a post you can dislike it, which will generally make it show up less to people. But on, say, Tumblr, not only are there no dislikes, but if you are really hate a post you can only respond to it by reposting it, therefore spreading it further among your followers! That’s an absolutely devious platform-design move that could have been invented directly by Satan himself.)
