  • Just some background on the cryptography going on:

    Its a hash of a fingerprint of your iris that isn’t used for access, it’s used for Sybil resistance, which is a bit different. You wouldn’t use this to prove you are eligible to vote, only that you haven’t voted already for a specific election.

    Under the hood, the iris scanning ball thing is just adding you to a membership registry. When you actually go to use your membership, you are generating a semaphore proof, which is a zero knowledge proof that you are in the registry with some nullification output so you can only participate in certain events some number of times (like voting once). You wouldn’t use this by itself to prove that you are eligible to vote.

    Generating secret keys from public data (iris)

    These aren’t exactly secret keys, but, yes, I agree. Also the Minority Report vibes weird me out.








  • Ya Ikea standardized on hex because it’s cheap to mass produce. It definitely strips though.

    Torx has slowly been gaining popularity in the US for a decade or two now, but sadly Phillips is still pretty popular and hex is pretty common also, you will see the square/Robertson screws a lot in electrical panels and in cabinetry but not super common at the hardware store.


  • The way I see it, anything with a square bit can be done by with a hand held screw driver, and anything with a torx bit should probably be torqued to a certain amount and/or be used with a screw gun. Square/Robertson bits are used super often in things like electrical panels and electronics. They are becoming pretty common for cabinetry also. I doubt you’ll see a torx screw in cabinets.
