Wikipedia tells me that iron has a density of 7.874 g/cm^3. A 60-foot-diameter asteroid has a volume of 4/3*pi*30^3 cubic feet, or about 113100 ft^3. So, units tells me that an iron sphere that size would be about 27,800 tons. So it's not as dense as a solid iron asteroid would be.
"There are seven balloons in total. Two are red. How many are not red?"
The spot for the answer has ___ + ___ = ___
The question is asking a subtraction problem, but has an addition sign in the space for the answer. That could be confusing for a five year old.
It's confusing to an adult who's very familiar with mathematics as well. They failed to specify that only two balloons are red. So the number of non-red balloons is less than or equal to 5.
A few months back, I read about a wax heat sink that could allow processors to turbo to very high speeds for very short periods. But...
Unfortunately, dealing with the heat created by sprinting isn’t the only issue that needs to be resolved. Even if wax is up to the task, there needs to be improvements in battery technology before such a system would work in a portable device.
Intel engineer Steve Gunther told Wired, “if I can’t get the current out of the battery it doesn’t help. You need balanced solutions.”
Because a wafer of pure silicon has a high, fixed cost. The smaller you can make a chip made from that wafer, the more chips you can make and the lower the cost for each chip. Intel's recent 22nm chips have recently been around 200mm^2. If they were made on 640nm, they would be about 200*640/22=5800mm^2, or a square of about 7.6cm (3 inches) on a side.
Also, smaller wires use less electricity and generate less heat. You wouldn't want 640nm Haswell in a laptop.
I have an Asus Transformer TF300. I bought it about six months ago. It was on sale with the keyboard for about $350. It has a 10.1 inch HD touchscreen, and a keyboard with 'signature Android buttons for "home screen", "previous"'. (No Apps Screen button, but nothing's perfect.) Its screen doesn't swivel, but it does detach. It also has a camera, a microSD card slot and an HDMI port like the Lenovo, plus a USB port on the keyboard.
Like they say, the stone age didn't end because we ran out of stones. We just have to get to a point where fossil fuel recovery is more expensive than solar and wind (and solar and wind power stored in batteries.)
In 3001: The Final Odyssey, Arthur C. Clarke wrote about a petabyte tablet as though it were the ultimate storage medium, something humanity finally arrived at after a millennium. In the book it was enough to store the contents of a human brain!
16,000 or so microSD cards could store a petabyte in roughly a 1-foot by 1-foot by 2-inch space, probably leaving enough room to wire them up as well. Of course, it would cost nearly a million bucks, not counting the hardware necessary to wire it up to be accessed. But, still, I find that very impressive.
Few American commentators seem to be questioning the unstated assumption that spying on non-Americans is perfectly OK, even if there is no reasonable cause for suspicion. By that logic, it's perfectly OK for other countries to spy on all Americans.
Furthermore, we assume that it's perfectly OK for America to share its intelligence with other nations and for other nations to share their intelligence with America. By that logic, it's perfectly OK for America to spy on everyone, as long as it's not technically Americans spying on Americans.
Finally, scientists thinking ahead. When the zombie apocalypse is upon us (Thanks to the effort next door to these guys) we will have a stable food source to keep them appeased.
This thing is heavier than some ultralight helicopters.
If you want an ultralight helicopter, they're available for as little as $6,000.
FYI, My wife will not be happy about you providing that link. You did a baaaaad thing:)
I, on the other hand, can't think of a more fun way to get myself killed! Well, not for the low, low price of 6 grand, anyway.
I, on the other hand, would prefer to avoid the risk of falling to my death. So what I'd really like to get is something like this. It's an Oculus Rift + a quadcopter. (But the model they use there is too expensive.)
wget is a web client - you know, like the one you're using to read this comment. It bears watching just like any other web client bears watching.
But wget is a special web client in two ways:
1. It doesn't display what it downloads, at least not in a human-friendly form. So its most likely purpose is to locally store the data it's downloading. (cURL fits this criterion as well.) 2. It is designed to be capable of collecting large amounts of data at once.
Now, one could argue it might profit them more to pay attention to what data they make available to web clients.... But that would be all... I dunno, sensible.
True as well. The web servers should be either on an intranet air-gap-separated from the Internet, or at least behind a good firewall. And in either case those with access should be searched for data being taken out. But that doesn't mean the use of wget doesn't deserve special attention above and beyond most other web clients.
In the Manning case, the prosecution used Manning's use of a standard, more than 15-year-old Unix program called Wget to collect information, as if it were a dark and nefarious technique.
Maybe it's not quite that, but if it's used to download information that shouldn't be collected by an individual, it certainly bears watching. One would hope that the military now flags anyone using it on classified information. Though of course there are plenty of other ways to collect such information, or to hide the fact that wget is being used.
Apparently nobody with mod points looked this up. Although I guess if you have to look something up to get the punch line of a joke, maybe it isn't very funny.
Only if the language you're using is pain. In other words: If you're trying to use C/C++/C#/Java/Pascal/⦠to write highly parallel code... YOU'RE DOING IT WRONG.
Those languages are not made for that. Don't try to shoehorn parallel programming onto them.
This is a far more elegant task in functional languages like Haskell, which are from ground up designed for parallel processing.
But GPU programming isn't just about parallel programming. It's also about low register availability, high memory latency, complicated memory access patterns, and just-plain-strange inter-process communication. The GPU has many more parts than a CPU, and you need to learn to use most or all of them effectively.
I couldn't find video of this year's match, but here's video of last year's. The robots in question are not humanoids, and not like those shown in the video in TFS.

Q11 is not fine. The question was:

At which point it will promptly be nicknamed the "bulgin' particle", because it makes all other particles more massive.
But clean technologies are taking off quickly.

Actually, I do, and with the back of my fingernail. Both slide more easily than the tips of my fingers, generally.

Thousands more exoplanets coming your way! Good news indeed.
I don't want even one exoplanet coming my way! I want them to stay in their own solar systems where they belong!
From there you could point them at http://www.try2hack.nl/ or something.

Although maybe your definition of "completely redesigns" is more extreme than mine?
Yeah, what is the point of "commercial" drones?
(If they are to be used for Law Enforcement and anti-terrorism domestic surveilence I would say thats not 'commercial'
TV news stations might also buy them. A 1-foot-square quadcopter is much cheaper than a real helicopter.

Funny, I've never had any problem with Strawberry Perl on Windows. Can't recall any problems with Cygwin either, though I haven't tried it in years.
Easier to take a static photo of someone with a good optical zoom than to film them while they're doing the facial expression in question.

You are completely right, food like this would likely not contain any fibres.
