puwaha, if a computer or device is purpose built to transmit data over the powerlines, yes, it can do that. But to claim that a generic PC from a run of the mill manufacturer has this built in as a backdoor is utter stupid.
By the way, I initially thought your back and forth with the other guy would keep this thread alive and may be generate some traffic, but if the thread is full of his nonsense on topics not even on a tangent, it would actually hurt us. Just ignore him. I think plenty have understood who represents what in this thread and community.
You are right. I was hoping we could get into some finer points like how a power factor circuit in a switched power supply is designed to smooth out a rectifed AC to DC conversion thus destroying any "command and control" that a bad actor like the NSA could possibly use in one-way communications with a compromised computer. Or how the loop-back DC circuit could supply some bad and possibly interesting harmonics if a C&C signal did somehow make it through. I could have been an interesting discussion. But I'm done with it.
Back on topic... I think the devs are getting way too much flack for their decision to delay introducing any POW algorithm changes. Their decision was a hard one, but ultimately their decision was based on the security of the network which is more important. I know many GPU miners are disappointed, but changing to a new algorithm opens them up to new 51% attacks from another Nicehash GPU onslaught.
When the equihash ASIC were first announced, I saw a little bit of a knee-jerk reaction from the devs and that worried me. They had a few months to consider some options, but this kind of change is not easy. I like the position that they would rather be the leader of an algorithm, than just chase their tails trying to prevent ASICs every six months like Monero is trying to do.
They need to complete their consensus changes, and then take a look at alternatives like ProgPOW, MTP, etc.
Ultimately it's the features of an altcoin that will make people want to use it, not whether it can be mined by a GPU or ASIC... that's petty stuff.
