Re: How can you verify the randomness that's coming from a hardware?
Well I don't know how you come to that conclusion but the only way I would believe it is if I seen it with my own eyes. I'd like to test RDSEED out and see what it can do. But in the mean time, feel free to share a 10 MB file of output from it so it can be statistically analyzed. Then we have something to talk about. 
You believe in so many things that you never saw with your own eyes, so I don't know why this would be any different.It's common sense and you can ask any tech expert that understands more how to achieve random results, but if you want to continue playing this game, than go for it.
They haven't. Intel's Management Engine is still being included in every chip they produce.
Their main competition is called AMD Platform Security Processor (PSP), but it is almost the same thing like in Intel microchips.It's not impossible to minimize both of this processes in some machines, but this is not exactly newbie friendly task.
Now I know that Management Engine has no reason to be used on home systems the way it is designed, but if someone really doesn't like this feature, they can run a version of the Linux kernel that has disabled vPro support (and whatever the counterpart is called in AMD). No need for strange rituals of using ancient hardware with obscure distributions like what Richard Stallman is doing.
It's impossible to really disable this with kernel or any software patch, because this is hardware based problem.Even with installing special BIOS version that have option to disable Intel Management, you are not really disabling anything.
