  • These images, while very intricate and pretty, are not fractals, and actually show a very interesting limitation with AI nowadays. Image generation AI tools such as Stable Diffusion or Dall-E don’t actually know the meaning of the words you’re using to prompt them, they just have a pretty good idea of what sorts of things pop up if you search for those words.

    A fractal is, by mathematical definition, self-similar. You can zoom into part of the smaller detail of a fractal and find the original image, and do the same with the details in the zoomed image, and so on and so forth ad nauseum. Computers are pretty good at making these, once they’re given the rules.

    What the image generation bot has given you is an image that looks like a fractal, and that’s what it’s supposed to do. In the same way that large language models like chat-GPT will be very confidently wrong about the information it tells you, and for the same reasons, image generation AI should not be used for important topics that the prompter doesn’t already have some background information about, such as generating a map of some place the prompter has never been in preparation for a road trip.

    Thanks for coming to my TED Talk.










  • For SSD’s, it’s 100% a logical table, because data is stored all over the place for load balancing purposes, so it already uses a logical table to keep track of what each block is for at any given point in time.

    For HDD’s, historically they were physically separated, and they mostly are still, but there’s still a logical table, and there’s no reason the logical table can’t say “Blocks 0 through 1234 and 2000 are part of partition 1” if you have something somewhere else that you want on that partition.





  • Step 1: Find the area of each chunk. The biggest chunk is your main chunk.

    Step 2: Find the distance between the closest edge of main chunk and the center of each other chunk individually.

    Step 3: Discontinuity of each chunk is area of chunk * distance from main chunk / total area.

    Step 4: Total discontinuity is sum of each chunk’s discontinuity.

    Bolded parts are important. If you use the center of the main chunk, larger main chunk radii make other chunks seem more discontinuous than they should be. If you use the closest edge of other chunk’s, you don’t account for the entire area of the other chunk.

    This will give you a number that is bigger when there are more and/or bigger pieces that are further away, and smaller when the opposite is true, normalized for the total area of the country so bigger countries aren’t penalized just because they’re bigger.


  • Make sure your litter box is clean, and that your cat thinks it’s clean. Cats want to be able to bury their waste, and if there’s too much in the box for the cat’s liking, they’ll go somewhere else, and it’s often right outside the box if there isn’t something else they could use. It’s important to understand that it’s the cat’s opinion that matters here, not yours: you may need to scoop it every day, even if there’s only a little in it.

    You may also need to move the litter box and clean the previous area, including and most importantly the place outside the litter box that gets used. Use vinegar if you can: it has a strong smell that cats don’t like, but it won’t hurt them like bleach can. Lemon juice works well for this, also. What this will do is make sure that this area doesn’t smell like a place they have used as a litter box before.
