  • Could there be patterns in ciphers? Sure. But modern cryptography is designed specifically against this. Specifically, it’s designed against there being patterns like the one you said. Modern cryptographic algos that are considered good all have the Avalanche effect baked in as a basic design requirement:

    https://en.m.wikipedia.org/wiki/Avalanche_effect

    Basically, using the same encryption key if you change one character in the input text, the cipher will be completely different . That doesn’t mean there couldn’t possibly be patterns like the one you described, but it makes it very unlikely.

    More to your point, given the number of people playing with LLMs these days, I doubt LLMs have any special ability to find whatever minute, intentionally obfuscated patterns may exist. We would have heard about it by now. Or…maybe we just don’t know about it. But I think the odds are really low .







  • I just looked it up and…

    SF6 has 23,500 times greater global warming potential (GWP) than CO2 as a greenhouse gas (over a 100-year time-frame) but exists in relatively minor concentrations in the atmosphere. Its concentration in Earth’s troposphere reached 11.50 parts per trillion (ppt) in October 2023, rising at 0.37 ppt/year.[8] The increase since 1980 is driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF6 gas contained in its medium- and high-voltage switchgear. Uses in magnesium, aluminium, and electronics manufacturing also hastened atmospheric growth.[9] The 1997 Kyoto Protocol, which came into force in 2005, is supposed to limit emissions of this gas. In a somewhat nebulous way it has been included as part of the carbon emission trading scheme. In some countries this has led to the defunction of entire industries.[10]

    Umm wtf? Why are we selling this stuff in compressed air cans ? Even methane is “only” 30x more potent than CO2 .








  • VR has been around in modern form for more than a decade and the only truly novel and useful application is some types of gameplay.

    There are a few other legitimate applications. Architects can offer people a 1st person view of a designed building. There are already companies that let people do VR walkthrough of homes they’re considering buying rather than in person open houses (I think this started in the pandemic).

    These things have value but they’re niche applications that can be done with any VR headset.


  • Has anyone identified the “killer app” yet?

    I still don’t see it. I watched a lot of review vids just because it was interesting but I don’t see a single thing that the Vision Pro can do that can’t be done better with other devices.

    The tech and computation required for those avatar things is amazing . It might get much better soon. But even if it does, will it be better than simple FaceTime type video conferences?

    It’s not clear to me how apple even imagines people using the thing.

    If you’re using the android Auto app then I don’t see how the OS even matters. You can turn off Google location services but I’ve never tried that with android Auto.

    You have to sacrifice something. It’s generally not possible to use cloud-based services while maintaining total privacy - at least not in a way that’s convenient.

    Here’s what you can do - get a car with minimal tech built into it’s head unit. Get a new head unit and get a car audio shop to swap it out for you. This will void your car warranty if it’s new, but some HUs have navigation built in (not Internet dependent ) and support simple Bluetooth .

    If you want full Android Auto capability then idk if it’s even possible to meet all your stated requirements.
