  • So let me get this straight. They are not exposing it to consumers. Everyone is being explicit that it is NOT exposed to CONSUMERS. Doesn’t that leave it open to being exposed to non-consumer entities? Things like Meta internally and government entities are non-consumer entities. I believe other businesses could be construed as non-consumer entities as well. So they could easily NEVER expose this to the end users and still make bank selling the data to brokers, government agencies, or private surveillance companies like Palentier or Flock.

    Cool cool cool… Good to know.





  • The point on this is the cars are broadcasting the numbers. Imagine your license plate including a loud speaker that shouted it’s number while the car was running. Tracking via plate requires line of sight. Tracking it in an automated way requires a good high speed camera, text analysis computer vision to log the vehicles, and storage for all of the images. In contrast, this signal is a repeating unencrypted broadcast. I could build a Raspberry Nano device that I can sit next to an intersection and capture the numbers of every vehicle that drives by. It is also just presumably storing the number and time, so years of tracking data could be managed with a gig or two of storage.

    This is absolutely a threat, and I am surprised it is not actively exploited by companies like Walmart to track every vehicle which drives by their stores and enters their parking lots. Hell, Amazon has enough vehicles out driving around that they could pretty effectively generate profiles for every vehicle in a town just by equipping their trucks with scanners and compiling the data into a behavior analysis system. Every car which drives past is read and stored. It is truly worrying.








  • You mentioned the areas being countries. This leads me to believe that they are concave figures, correct? If you are unfamiliar, a concave figure is something that has a space that doubles back into the interior of the shape. So an o is convex, and a c is concave, as an example. Convex shapes are much simpler to find the area of. You can use a Riemann Sum as others have suggested. I would probably just pick a point inside the shape and do a bunch of triangles around with the point as an apex and the bases as two points on the edge of the surface, then sum up the areas of each triangle. You could even probably use a triangulation algorithm built into the engine to do this. (I am unfamiliar with the specifics of the Godot engine).

    For concave shapes it becomes a little more complex. It has been mentioned that you can draw a bounding box around the shape, so that would allow you to calculate it using a numerical method. Take random samples inside the bounding box and count up the number that are inside the shape and divide by the total number of samples. The value you get will be the % of the area of the bounding rectangle that the shape takes up, so just multiply the easy area by the % and you will get an answer that is close enough. It may take a bit to get the sample count right, but it will get there. Try to make sure the samples are as uniform as possible. You could even scatter the sample points then relax them for a couple iterations before counting to increase accuracy without increasing samples.








  • Indeed. I agree with everything you said here.

    Most of my quandary stems from patants at this point I guess. Copyright reform advocates are plentiful, but patant reform is much more rarely mentioned and IMHO is a bigger issue for progress and development of society. The anticompetitive practice of purchasing patants so you can bury them gets deep under my skin. There are so many things that have been invented, problems that have been solved, potential progress that has had the first steps made, that was squelched because some person/company with more money than civic duty realized that it would negatively affect their revenue stream. And instead of developing the idea and incorporating it to make their own products better, they just hide if in a vault somewhere.

    That all said, I cannot describe how happy I was when I heard of some rogue patant whore activists out there coming up with ideas for enshittification and patanting them so corpos cannot use those specific methods to enshittify our world more. I wish I had been able to patant the SaaS architecture when I graduated HS in 2003. Maybe the world would be a much better place.
