Wouldn't that result in time based patterns matching the daytime/nighttime cycle? Then again, I guess this would only happen during continuous use over a number of days and perhaps that's not the use case.
- H8crilA 3y agoIt still adds entropy. You're thinking of uniform entropy vs just entropy, but the former is easy-ish to produce from the latter, for example by using hash functions. Also, it's obviously a stunt - you are probably much better off measuring decay of trace amounts of natural radioactive isotopes. But it is not without merit.

- Miraltar 3y agoYes there is a day/night cycle but it also depends too much on the weather on a ridiculously tiny scale to be realisticly predictable. And even if it was indeed predictable, it woud still add complexity to the prediction
