|Huh? That's not correct. You can still introduce entropy into the

Ah, lesser and lesser freedom for man! That is the truth!
Neither was (last i looked) that counted no more to unlock man
from the chokehold of missing entropy, nor do newer kernels then
decrement entropy when you read random.

Surely for the latter. So much i give in on this song line.
