The numbers in the article suggest break-even in about a year. It seems like a fairly straightforward win for the Indian rail system, and using more solar panels makes them cheaper for everyone else.
Of course you wouldn't. Just like you wouldn't put them where "there are times of the year (winter) where both of those sources produce 0 electricity during the day."
There will be big solar plants in sunny places, mostly in the south, big wind farms on the coasts and offshore, and hydro, geothermal and others everywhere else where the resources exist.
You won't need "multiple weeks of storage" in case of a storm. If some weird weather shuts down whatever you use locally, you'll suck power from the grid just like you do now.
You're using off grid math. You wouldn't put your big solar plants where there is no sun in the winter. You wouldn't put your wind plants where there's no wind.
Long distance high voltage dc works pretty well. There are also other solutions, like making, moving and burning hydrogen.
That's the key. The statement that we can't see what's going on inside them is demonstrably wrong. We can. The statement that our visual monkey brains can't easily *understand* what's going on inside them is correct. But then our monkey brains don't understand what's going on inside themselves in all but the most trivial circumstances, and we actually can't see what's going on inside those, so we're actually a fairly important step ahead.
It's as easy to understand as anything else. The trick is to figure out how to take those numbers and turn them into a visual representation that our monkey brains can parse.
Much of analysis is turning things into visual metaphors that our monkey brains can parse. Graphs, infographics, XKCD....
Tabs on a typewriter let you easily indent to a manually settable, consistent position. They eliminate errors where you're off by a space or two, start typing, then have to get out the corrector tape and fix your crooked column.
Word processors copied that behaviour, with the tab character meaning a user-selectable level of indentation.
The tab character seems like an ideal symbol for an indent in code to me, particularly in whitespace sensitive languages: being off by a full tab is obvious; being off by one space out of four or eight might not be. The problem seems to be that various text editors historically insisted on converting tabs to spaces. A third of the coding population hasn't figured out that you can turn that off, and another third is so traumatized from past experience they won't even consider alternatives. And the last third uses tabs.;)
Yes, that's a feature. If you're the kind of jerk who tries to align code at sub-tab resolution then you can't, at least in whitespace sensitive languages like Python. If you want to align your pretty comments that way, go ahead and use spaces, because it doesn't make the slightest difference.
IBM doesn't want to piss off their customers (radiologists buy the radiology-related equipment).
IBM came to the hospital where my lab is to talk about their genomics platgorm, but threw in a demo of Watson assessing a patient in the ER, ordering a CT, evaluating the CT and prescribing treatment. They're playing it smart: tell the radiologists you have a great new tool to help them. Then let nature, economics, and hospital administrators take their course.
It costs about $500 for an hour long MRI, including the tech to run the scanner. We used to joke that the radiologists made $250 for sticking a film up on the screen (that was fifteen years ago or so). They're a little slower now, but they can still read most scans in closer to five minutes than half an hour.
* Figures may vary in crazy parts of the world, such as the USA.
Not so much anymore. Unsupervised pretraining lets the machine learn from unlabelled data. Most of the labels actually come from the followup. Did that patient have a brain tumor? You don't ask the radiologist, you ask the pathologist.
Emergencies are even more reason to have a computer do the reading. The computer works 24/7, with at least 99% uptime. The human? Not so much. I work with radiologists. They're wonderfully trained. But they can only know so much, make mistakes, and want to go home to their families. They ignore or don't hear their pagers sometimes. Computers don't.
Ah, you'd like to volunteer for a double blind interventional study? Excellent! Assuming you are young (20 or so should do it) we will give you a mystery beverage every day, which you must drink. When you die we'll record what killed you, and open up the envelope to determine what it was we were feeding you for the last fifty or sixty years.
That seems unlikely. You might be able to specifically build a power supply that would damage a battery, but you'd probably have to go out of your way to do it. The actual charging hardware for an iPhone is inside the phone: the "charger" just supplies power, and isn't likely to be any worse at doing that than some random USB port.
He said "normal people." Apparently that means people who can't work a screwdriver and follow a step by step tutorial on iFixit.
I've replaced several iPhone batteries, and screens. Battery takes ten minutes or so. Screen is usually slightly more fussy, maybe 15 min. I'm sure a repair guy who did more than one every year or so could do it much faster.

Why? What is it about your brain that you believe makes it so special that it cannot be duplicated by artificial* means?

That's not bad at all. I'm surprised it's so cheap. What's that, one year of a medium sized war?
Presumably you wouldn't try to do it all instantly. Build it up over ten years.
Pyros.
I admit it: gas ranges are pretty. Like that oversized gas flame they always had going in the mess on Voyager.
In terms of actual cooking? If you can't figure out an electric stove you probably shouldn't be using a gas one.
You know, someone (you?) did the same incorrect math on another story. I corrected that one. Here you make the same "mistake".
Hmmmm.

You speak of intelligence as if it were something magical, more than optimization and model fitting. Curious.

control + shift + arrow plus delete is four keypresses. Might as well just hit delete four times. Or use tabs and hit it once!

Yeah, but when you're deleting those "tabs" you have to hit backspace four times instead of one.
Plus your code is bigger because it's using four+ characters to encode a single tab.

The result of the study is precisely what the summary and the article say. From the first line of the article:
"People who drink coffee have a lower risk of dying from a host of causes, including heart disease, stroke and liver disease, research suggests...."
What comes after the ellipsis is actually this:
" – but experts say it’s unclear whether the health boost is down to the brew itself."

I've never had any luck with eBay batteries, unfortunately. Not for phones, notebooks, or cameras.
