No. X^2 does not increase exponentially with X. It is not "exponential" in any meaningful sense. Would you say that X=1 is "exponential" with an exponent of zero?
When mathematicians, or algorithm designers, say something is "exponential", they mean it is a function with the variable of interest (in this case, the height of the hill) in the exponent. The volume of a hill, as a function of its height, is NOT exponential.
The autonomous system cannot determine if the road 100 meters ahead is covered in a thin sheen of black ice or not.
Yes it can. Tesla cars transmit data back to a server, which can then inform other cars in the area. I don't know if it transmits traction data, but it certainly could.
Also, black ice tends to form in the same stretch of road when the conditions are similar. So an automated car could reference historical accident data for the road it is on, and slow down before reaching hazardous spots.
It's hilarious to me that people cite "ice" as an example of their precious human drivers being superior to machines,
Indeed. When a big snowstorm was predicted, Tesla sent out an email to inform owners that they should use Autopilot during the storm, because it would handle the hazardous conditions better than most human drivers.
both gold and diamonds are useful for manufacturing, medical treatments etc.
Only a tiny fraction of gold is used in industry. Nearly all is used to store value as either bullion, coinage, or jewelry. Gold mining is terribly destructive, creating erosion and mercury contamination. Most industrial diamonds are manufactured, not mined. Diamond mining fuels wars and funds corrupt governments.
It is funny to see Americans complain about the shit in these agreements, when the worst shit was put there by their own government.
These trade agreements could be a force for good in the world, raising environmental standards and labor rights, while spreading prosperity. But instead, America uses them to push the worst aspects of our capitalist system onto other countries, like draconian IP laws and disregard for consumer privacy.
A shift of a few degrees C is nothing compared to normal seasonal variation
For people, that is true. People are not going to die of the heat. But their crops and pastures will dry out. So the people will either move or starve. The problem is that there is no where to move to. Even Syrians, who are more educated and secular that most other Middle Eastern people, are not wanted anywhere.
I'd guess at minimum, plant respiration would be hindered due to higher rates of evaporation.
Plants lose moisture through leaf pores. The pores are open to absorb CO2. As CO2 levels go up, they can absorb enough CO2 through fewer and smaller pores, so they lose less water. So higher temps will be bad for plants, but the higher CO2 levels will help mitigate the problem somewhat.
I'm probably an asshole too, I'll grant that, but I can at least wipe my own ass without telling 10 people whose fault my shit is.
Maybe you should try to be more approachable and proactively helpful, and then your co-workers would not try to work around you and complain to your boss.
Just how much energy has been wasted mining bitcoins over the years.
Bitcoin mining is done where electricity is cheap, which means baseload hydropower in places like Iceland or Oregon. So the only "waste" is water flowing to the sea at a slightly lower velocity.
This guy, and anyone that uses Bitcoin, is a drain on society and resources.
Compared to what? Would we better off if people mined more gold and diamonds instead?
Switching to LED doesn't change the generation mix, or curb the huge demand increase projections China has, not even close.
I was talking about Britain, where Hinkley Point is being built, not China. Power consumption in Britain is declining. With more incentives for LED lighting, and more efficient appliances, it could decline faster.
I suspect (yes, I'm guessing) that this may be somewhat less expensive than a Tesla K80.
Sure, but it is more expensive than the GPU already included in your computer, which has a marginal cost of $0 since you already have it. So why should you buy something that is far slower and less capable than something that is effectively free?
Also, you don't need to buy a Tesla K80. You can rent them by the minute from AWS.
For pete's sake let's get real here. Rolex starts from several thousand dollars, more than 5000 $ for a stainless steel watch.
Apples and oranges. The Rolex can last a lifetime. The Apple Watch needs to be replaced every few years with the latest model. The TCO is higher with an Apple Watch.
The point of fashion is to draw attention to yourself. If you wear a Rolex to a cocktail party will anyone notice or care? I don't think so. But if you wear an Apple Watch, people will notice, and it might even be a topic of conversation, especially if you know how to demo some cool features.
Disclaimer: I do not own a smart watch. But I do have a fake Rolex that I bought for $10 in Guangzhou.
But when a stainless steel band is $300....all you can say is Apple has lost their marbles.
No, Apple is being smart. They have realized that Smartwatches are not technology products, they are fashion accessories. The Apple Watch is not competing with Samsung, it is competing with Rolex, Bulgari, and Patek Philippe. They need to keep the price high to make it exclusive.
We should first create AI before we start selling it on fucking USB sticks.
We have created AI. What we haven't done (yet) is create human level general purpose AI. But you don't need GP-AI to do things like object recognition, basic natural language processing, machine learning, etc. All of that is still artificial intelligence.
This is all very interesting. However, there is no indication of when the sticks will become generally available.
There also seems to be very little actual information about it. How much memory does it have? How many FLOPS? The product sheet says it uses 16 bit floats, which are generally good enough for NNs. But can it do FP32 and FP64 at all? The power consumption is ~1W, so I doubt if it can do much with that. The USB interface would be a major bottleneck, as you fed information in, and pulled results out. A GPU on a PCIe bus would be way faster at that... and nearly all computers already have a GPU. I think I will continue to run my NNs on a Tesla K80.
I drive an old beat up minivan. She won't let me drive the Tesla, but sometimes she lets me sit in the passenger seat. Free advice: Don't marry a woman who earns more than you do.
So, rather than just being 2x more efficient baseline, electric vehicles are 3x as efficient?
That's about right. ICE+transmission delivers about 15% of fuel energy to the wheels. A gas turbine power plant + battery + charger delivers about 45%. So you get about three times the miles for a given amount of fuel. But gas/coal is much cheaper than gasoline, so the cost is much less than a third. Also, gas and coal are produced domestically, generating jobs for Americans. Petroleum is often from Iran/Venezuela/Russia or other people that hate us.
Canadians and Mexicans would disagree. They think America benefited and they got screwed. Most economists would also disagree, except they believe that all three countries benefited.

It's time to start steering our kids towards climatology and related fields.
This hill will be built by civil engineers, not climatologists.
The problem is the exponential increase in material required to gain any useful elevation.
The increase in material would not be exponential. It would be a quadratic function of the height.

Even if biological systems worked as batteries (they don't), why wouldn't The Matrix use something more docile than humans, like cows?

Yup, that's the best new pyramid scheme that was created since the beginning of time! :D
No, the greatest pyramid schemer was Khufu.
I'm surprised about this amount, I guess that most people are afraid to get caught donating to this site
Or it could be that people that want something for nothing aren't willing to pay for it.

No 3 Gorges estimate here?
3 Gorges was projected to cost about $22.5B. The actual cost is believed to be a little below that.
3 Gorges produces 23GW. Hinkley Point is designed to produce 3.2GW. So that is ten times 3 Gorges based on cost/power.
Maybe instead of building this new power plant, they should just convince more people to switch to LED light bulbs.

There's a BO tax here to discourage startups.
Couldn't they avoid that tax by using deodorant, or by showering more frequently?
NAFTA has certainly hurt us.
