| Could this be used as "shake your mac for highly random seed" bits? |

| There's lots of noise in the accelerometer readings, even without shaking |

| Shake your Mac to undo would be consistent with iPhone, iPad, Vision Pro. Yes, you shake your head to undo when wearing AVP. |

| Probably not as random as you want it to be. |

| ▲ | sysguest 9 hours ago | parent [-] | | well wouldn't it add up? someWhatRandom1 xor someWhatRandom2 xor notRandom3 xor ... should be more 'random' than just 'someWhatRandom1' | | |
| ▲ | throawayonthe 9 hours ago | parent | next [-] | | i'm not sure it would necessarily be more random if you're mixing in a lower-entropy source which the accelerometer probably is | |
| ▲ | LoganDark 8 hours ago | parent | prev [-] | | XOR is the worst hashing function imaginable, especially if the data isn't truly random, because it can cancel out to become even less random! It's better to use a KDF or something. Even a block cipher should work far better than XOR. |
