I don't want Linux sampling my microphone randomly. Other things are fair game.

- logfromblammo 13y agoI don't recall who did it, but someone once pointed a webcam at a row of several lava lamps as a source of entropy. As long as at least 75% of them were on at any given time, the image-hashing function produced unpredictably random numbers. The low quality of the camera produced some random noise all by itself. I imagine you could do something similar with a feed of traffic on a nearby highway or blobs of cornstarch suspension on a subwoofer.
- MAGZine 13y agounexpectedly amused by the fact that in this case, worse hardware is better due to extra noise.
- cobbal 13y agoYes, but I suspect the NSA has had the foresight to backdoor most major brands of lava lamp. Same problem as before, you can't easily verify the hardware.
