  • I pretty sure that’s not what non-Eucludian means. It’s not just built on a rounded surface. The lines of latitude and longitude we define on a globe may exhibit non-Eucludian geometry, but that doesn’t mean your house is non-Eucludian.

    These things are non-Eucludian: parallel lines that diverge or converge; triangles with interior angles don’t add up to 180 degrees; hallways that appear perfectly straight, but also intersect with themselves; square rooms where every wall is perpendicular, but opposite walls aren’t always parallel. Brain breaking stuff, not “all of our geometry”. That would be dumb.








  • This video says it both ways I’ve heard. The white people around me pronounce it like the one with the union jack (heavy emphasis on the B), the Spanish speakers pronounce it more like the version with the American flag background (ironic). Most of the other pronunciation videos I could find seem to be made by AI voices and mangle the pronunciation in a myriad of ways. This other video has an actual person speaking well (I can’t speak to the rest of the content of the video).









  • Dark table corrects lens distortion based on the design of the actual lens, not the image itself. The grid it just to check in after the fact. I’m not aware of similar tools in GIMP. It’s trivial in Darktable though, as long as your lens is in the database.

    Don’t use a fish-eye lens, it’s lense distortion will be the worst and most difficult to correct. Use a lens with a longer focal length, ideally a prime lens with a fixed focal length. If you maximize focal length and distance to your object as much as is feasible, you will have already flattened the image (minimized lens distortion) a lot. If you use a prime (fixed focal length) lens from a popular brand, Darktable can remove the remaining lens distortion.

    You can remove all lens distortion by using a pinhole camera, which has no lens. But that’s probably going to be a tricky setup without an expert.


  • The tracksuit and matching Adidas sneakers are kind of a give-away. Anyone can buy a hi-vis vest. No way a security guard or worker would be dressed like that to do any real work up there. And absolutely no way they would risk their life or their job to stop some nutter getting their Darwin award. Even if successful, they’d be fired for exposing the company to liability. They’d just wait by the door and have them trespassed on their way out.
