  • This whole post is a good illustration to how math is much more creative and flexible than we are lead to believe in school.

    The whole concept of “manifolds” is basically that you can take something like a globe, and make atlases out of it. You could look at each map of your town and say that it’s wrong since it shouldn’t be flat. Maps are really useful, though, so why not use math on maps, even if they are “wrong”? Traveling 3 km east and 4 km north will put you 5 km from where you started, even if those aren’t straight lines in a 3d sense.

    One way to think about a line being “straight” is if it never has a “turn”. If you are walking in a field, and you don’t ever turn, you’d say you walked in a straight line. A ship following this path would never turn, and if you traced it’s path on an atlas, you would be drawing a straight line on map after map.









  • There’s basically a tree of operations that have been applied to a model. At any point, you can go back and edit what you’ve done at a previous step. For example, if you padded a feature out 10 mm, then added more stuff onto that feature, you could still go back and change that padding operation to 15 mm.

    I’m still super new to freecad, and I haven’t done anything too complex in it yet, but my understanding is that some types of those changes can result in the topological naming problem. The way I understand it, when you make a shape, the software numbers all of the segments, vertices, and faces. If later changes are applied to those numbered faces, etc, and you go back and redo the operation that made those faces, etc, in a different order, the numbering will be different, and it will break your model.

    There is a fork of freecad that fixes that whole issue, but the fix hasn’t been implemented yet in the main fork cause it’s pretty foundational to the working of freecad, so there’s a lot of things that can break



  • Your title here isn’t technically wrong, but it is misleading. It should be "white AI faces judged to be more real than white human faces. The way you phased it insinuates that white AI faces are judged to be more real than a diverse mix of human faces.

    For anyone who doesn’t want to read the paper, they basically took an 60 white men and 60 white women, and showed them a whole bunch of white faces, half of which were generated by AI. It turns out that AI faces were rated as more human-like than actual humans, and they had some hypothesis why. Principally that AI, by its nature, generates images close to “average”, while real people tend to have features that are not “average”. The reason the study focused on white people is that most AI have been trained on white faces, so AI tends to do better with white faces.



  • Definitely noticed this as well. Wish I could filter out articles by certain keywords/phrases that pop up a lot. I know that’s an option for some of the paid rss readers, but it should be a pretty simple feature from a code perspective, so I don’t want to pay for it. It might drive me to actually learn how to compile my own app. I also want to get rid of any sports news from my local newspaper cause it seems like 50% of what they put out is professional, college, and even high-school sports
