    Ok, so this sent me down a brief rabbit hole on Wikipedia (https://en.wikipedia.org/wiki/Headlamp), from which I learned that the US is the only industrialzed country who have a different standard for headlights.

    The US SAE standard allows for much more glare on low-beams than the ESE standard used in other countries. That explains why I see so many complaints online over low-beam headlight glare, something I have only really found to be a little annoying over here in Europe. (Also, combine the “worse” standard with significantly larger cars to get even worse glare, I guess.)

    But what I was actually looking in the article (didn’t know what it was called) was Glare-free high-beam, which is a system that dynamically shades and lights parts of the high-beams to provide as much light as possible without lighting up other cars.

    From experience using it, I’m kinda torn. On the one hand, it does work, is really cool, and makes driving at night quite a bit easier and safer. On the other hand, it’s not perfect, and sometimes (not often, but still) it takes a bit to recognize another car or fails to recognize it completely. And when that happens, I am effectively blinding that other driver with my high-beams, which is bad.

    So far, especially on the Autobahn, it works well enough that I tend to use it, because being able to see nearly everything brightly at night is so much safer for me, and the few times it fails I can manually intervene.

    What exactly makes this stand out as AI to you, and not just cosplay?

    I can’t really find any of the telltale signs of AI. The books on the shelf all look fine, the mirror on the left edge looks perfect and I can’t find anything immediately noticeable on the costume.

    If this is AI, I think it’s probably just the face, maybe the whole person, but certainly not the whole picture. But maybe I missed something, please let me know.





  • One thing I don’t like about the “master key” metaphor: I do lockpicking as a hobby. And locks built for a master key are easier to pick, because you can open them with two keys. It seems kinda obvious when you think about it. (You gotta be careful when picking mastered locks though, the master wafers can fall into the keyway and permanently destroy the lock.)












  • Great write up.

    As an amateur radio enthusiast, I’d like to add a bit of info to the radio related tips:

    Wifi Motion & WhoFi

    Depending on how it works, a radio jammer will almost definetly make you more identifiable and not less. Think of it a bit like being in a dark room. You can sorta see other people (or their silhouettes), but if someone turns on a torch, then you can definetly see the torch. (And any jammer with enough power to “blind” a wifi router at any more than a few meters away only works at 2.4 GHz, or is probably illegal.)

    Radio

    (or “locating recievers”) This is physically impossible.

    Now locate a radio transmitter is easy. Ham radio clubs often do regular “fox hunts” where teams try to find a hidden transmitter as fast as possible.

    However, most digital devices are transmitting and recieving at the same time, for wifi or bluetooth. Even if you’re just downloading something, you are still transmitting (I think that’s probably what you meant).

    Another note on Wifi and Bluetooth

    This might be common knowledge here, I think I’ve seen a post about it before. When wifi/bluetooth are on, your phone actively searches for nearby networks/devices to connect to. It specifically looks for known networks/devices, and fingerprinting your phone based on which networks/devices it knows is incredibly easy.

    So, when you aren’t using it, turn wifi/bluetooth off.

    Also a note on Gait Recognition

    Walking funny usually doesn’t work.

    (sorry, no sources here, I’m in a bit of a hurry)
