Also, he awards bonus points for proofs of hardness. No one has managed to prove hardness for any existing block cipher. Block ciphers are simply ways to jumble the plaintext up in a reversible fashion. They are not based on difficult mathematical problems.

Proving hardness is something you do for asymmetrical ciphers, but asymmetrical ciphers are way too slow to be useful for actual messages.

Comodo is well known for lousy security. That they're still trusted by major browsers is a miracle. Never use any of their products if you can avoid it.

Then again, as far I am concerned there are only two reputable SSL vendors: GlobalSign and Let's Encrypt. The rest have either issued fraudulent certificates at least once or they simply shouldn't be in the business in the first place.

With my luck, that probably means that GlobalSign is secretly owned by North Korea and run by the Illuminati or something. Even then they'd be better than most of their competitors.

However, the FPU is powerful enough that it is unlikely that you can saturate it with only a single APU handling the integer side of things. It is possible that wwalker hit the FPU limit, but I would guess that it was some other scaling problem instead. Memory bandwidth or cache perhaps, or simply hitting TDP and throttling.

Getting 60% per-core performance on a 16-way isn't that terrible anyway.

Not that I would recommend AMD for anything serious these days, sadly.

Hydroelectric is a finite resource all by itself. Right now, particularly in North America, the strange political environment surrounding electricity distribution prevents hydroelectric power to be shared by the whole US, which means that you can add electricity consumption to hydro-heavy areas without increasing pollution.

Hopefully the US will soon realize that free markets are a good idea and implement a proper grid and a decent trading platform. When that happens, the bitcoin guys can no longer benefit from market failures.

The slickest thing would be to get a PoE switch which lets you cycle power on its ports. I have no idea if such a thing even exists, but I would have to bet it does.

Every managed PoE switch that I have seen supports disabling PoE per port. Some offer true power cycling support with just one command/one click, with others you have to turn the port off then on again, but they all have a way of doing it.

Do you seriously believe this stuff?

You are complaining about CO2 emissions before 1850! They were so close to nil that cumulatively, we can just ignore them. The world emitted more fossil CO2 last year than it did in the entirety of human history before 1850.

In fact, from 1850 until 1980, Europe was ahead of America in CO2 emissions.

There are more than twice as many people in Europe as in the US. You would certainly expect Europe to be far ahead of the US in CO2 emissions.

It was terribly tempting to just mod you troll. Perhaps someone else can come along and do it.
