I don't know what it's like in your country, but I've never heard of a house in Britain heated with a heat pump. Certainly mine isn't. So it's not a useful comparison.
I have a heat pump in my car, because it's an EV. But not in my house.
I'm afraid you failed Thermodynamics, Anonymous Coward. Energy in = energy out + energy retained. I'm putting electrical energy in, and I'm getting heat out. And over the long term there's no energy retained. The fact that those excited electrons in the GPU heating element happen to give me useful information makes not a scrap of difference.
In general yes. However if you use some rigs for domestic heating it's not a waste at all. A kW of electricity put into a mining rig will give you just as much heating as a kW put into an electric heater.
Actually impeachment is a political process, not a legal one, so it requires no law to be broken. It just requires enough politicians that want the president to go.
There was some guy from MIT on the radio this morning saying he doesn't see full autonomy for 40-50 years. Amazing the range of predictions on when this tech will be ready.
The point of monorails is you don't need land for the track, other than the small bits of land for the concrete pylons, and a bit of space at the stations.
Bad assumption. I'm from the UK, so first of all you need to swap left and right in your thinking. Secondly It's always been the law here that you keep to the left hand law unless you are going to overtake.
No I'm sorry, if you can get a ticket for going too slowly when you are at the speed limit in ANY lane, then that is two laws contradicting each other.
But it's not a heuristic on it's own. You also have safe stopping distances for a given speed. And if the car behind is tailgating and forcing you closer to the car in front, then your speed must slow down to maintain safe stopping distance. Safe stopping space for speed is always going to take priority over traffic flow maximisation.
In other words this heuristic should only be used when distances already exceed safe stopping distance.
Of course no human is going to do it. But it's a decent heuristic for automated cars.
Human drivers are going to be obsolete before long anyway. I see this as a heuristic to put in automated driving systems, which can easily monitor the space behind at all times. And yes, in the meantime ACC could use it. Although if people don't understand why the ACC does that, it might discourage them from switching it on.

Nope. You can't destroy energy with work.
2 acquaintances! Wow, well unless you've only ever met a handful of people that confirms their rarity.
Absolutely. James Damore continues to prove that Google were right to fire him.
It's far more common to heat houses (at least partially) with light bulbs than heat pumps. As far as I've seen anyway.

I don't believe thats so. The GPU miners are working on alternate crypto currencies. The one's that the ASICs can't mine.
The mining hardware won't be scrapped. If they managed to stop people mining in China, the machines will be exported to other countries.
Although China effectively banning it will make it easier for other countries to do the same.

Well, it sounds like there might be plenty of used Antminer S9's on the market before long at a good price.

"My type"? More bigotry.
"Always the man's fault". Oh, poor repressed you.

A racist would say the same thing.
The same as yours then.
Because that's the heuristic in TFA. And TFS come to that. Read it.
Bad assumption. I'm from the UK, so first of all you need to swap left and right in your thinking. Secondly It's always been the law here that you keep to the left hand law unless you are going to overtake.
I assume I'm a better driver than you are.
That sounds more like it.
... to enable other people to break the law.

Depends on the road. Depends on the quantity of traffic.
No it hasn't. You've never been taught to make the distance in front of your car match the distance behind it.
