We don't have enough fuel to actually send these things anywhere but down. As for why we don't just leave them there, usually satellites are usually decommissioned when they run out of some resource. For commercial satellites, it's usually the fuel used to maneuver, which means that it will no longer be able to doge debris so it's best to ditch them there, but for scientific applications, we often have a tank of liquid He or N2 somewhere used to cool an instrument. When that tank runs out, you have to ask if the other sensors are worthwhile to keep which occasionally they are.
If the probe is worthless, it'll just add to the satellite debris and 200 years from now it'll be a problem. But these things have a lot of kinetic energy and we really don't know what's even a foot underground on the moon so you might as well crash it and look to see what you find. As for why we're doing it at night, the moon has a temperature swing of over 200 degrees between day and night, we don't want any volatile compounds to evaporate before we get a chance to look.

I can understand Kodak owning some patents for digital imaging, but 1100? Are there really 1100 different ways of doing digital imaging, or just 1100 obvious ways of combining seven novel ideas?
I don't know, there's over 5000 different ways to combine 7 ideas. I'm betting it was 6.
Aspergers may be on the austisic spectrum, but they're nothing alike in real terms.
It's a spectrum! The EM spectrum is quite similar...
You can't expect people at the mild end to show the same symptoms and behaviours as those as the severe end. Let's be honest here, we're all on the autistic spectrum somewhere, and I can easily believe the slashdot crowd are skewed towards one end from the population mean.
Your analogy to the EM spectrum is quite apt here. Scientists know exactly what it is if they've been trained in Physics, EE, or Chemistry, pertly much nobody else knows what it means other than you have a poster with a rainbow on your wall. In a vacuum, they behave the same, but the equations that cover microwaves, visible light, and x-rays are very different when they become the least bit useful to you by reflecting off, getting absorbed, or traveling though stuff.
To Average Joe who will ultimately make decisions based entirely on a superficial name, radiation can be clumped into categories like... does it cook my food? Can I see it? Will it kill me? With the first and second categories almost never being called radiation because that's a scary word.
Since the Autism Spectrum is so wide and the word Autism has such a negative association, it'll end up in the people defined as Asperger's to reject their diagnosis as Autistic.
I don't think academics and/or achievements are priority qualifications for "leaders" of western institutions for a long time now. Ballmer, Carly Fiorina, Meg Whitman, Marissa Mayer, Steven Sinofsky, Julie Larson-Green, Obama, GW Bush, Bill Clinton... Nuff said.
Lawrence Tech, UCLA, Princeton, Stanford, Cornell, WWU, Harvard, Oxford... You sure picked an odd list.
2 hours?! For us, east coasters, 2 hours don't make any difference... for others will be too... soon enough...
And you can't use it in an off-grid solar setup - there aren't many charge/discharge cycles left...
It's difficult to read your post and understand what you are trying to convey; but I am assuming that you're talking about Hurricane Sandy based on your reference to the East Coast. This is not for that.
Yeah, because taxes are SOOOOOooo much lower in Canada and the EU than in the U.S.
Well...actually, yeah in parts of Canada they are. And if the $7b in taxes goes through at the start of next year happen, I'm sure those of us up in Canada will see American companies flocking to Canada.
You know, 7 billion in taxes is only about 200 bucks to each Californian. How much do you think it costs a company to move out of a state even? My guess is that for a small company it'd be on the order of tens-of thousands, without factoring in training costs and lost profits during the transition.
You have a choice between real people dying or computers catching a virus... The more effective we are in slowing down Iran's nuclear program, the more time we have before we need to resort to military action...
Countries weigh the cost vs benefits when engaging in a war, not all 'acts of war' are created equal.
If hundreds or thousands of citizens die in an attack like the USS Maine (Spain), RMS Lusitania (Germany), Peril Harbor (Japan), 9/11 (Afghanistan), the US responds with an all out war where both sides suffer causalities. Other cases like the theft of American's property (Cuba), an embargo is sufficient for us to tell them that we don't like 'em.
During none of the wars listed above did the US ever have a significant threat to it's existence even in the event of a loss, except maybe Cuba. But if you're Iran war would mean certain defeat, that cost calculation is even more skewed.
They're used to the gravity, you're not. They should be quite athletic by our standards and able to go all night, while you'd be wheezing just leaning against a poll.
Very true, there are other factors which may be contributing to our density like our lunar impactor which would have ejected lighter elements easier our our position in the accretion disk which would have provided us with supply of heavier raw elements. We also suspect that there's an upper limit for gas planets' volume based on gravitational collapse due to adding new material, one would expect a terrestrial analogue.
Taking pictures of bodies like Pluto isn't hard because it's far away from us, it's hard because it's far away from a light source and receives 1/2000th the illumination of the Earth, being small and far doesn't help, but that's not our big problem. Given that it's in the habitable zone, the amount of light should be comparable to that of the Earth, not something and given the expected surface area is nearly 4 times larger than that of the Earth's, it should be a quite bright pixel.
Assuming 2 planets have equal densities, Mass increases proportional to R^3, but gravity is proportional to the inverse squared of the distance.... As a result, surface gravity increases only linearly with the radius.... in this case, the planet would have 1.9 times the radius of the Earth if it's the same density.
Earth has a very high density actually at 5.5g/cm3, it's actually the densest planetary object in our solar system. Most terrestrial objects are closer to 2 and the larger ones tend to be 3. It is entirely possible that it'll have a comparable surface gravity.
When you get sick, I'd rather you get per-emotive care rather than wasting my health care money by rushing to the ER at 2 in the morning costing me 10 times more money.... but nope, you'd rather just get the benefits without paying.
"also provides excellent development tools for coding, testing, debugging, and distribution for free along with your developer subscription ($99/yr)."
Wtf is he smoking. They aren't free tools. They are $99/yr tools. He said it right there.
Now that you pay $99/year for it, it's free. Just like my car, computer, and all of my assets except for, no, even utilities are free once I pay for them.
The actual transmitter and receiver is nearly indestructible since it's mostly a copper wire wrapped around something inductive. The electronics are also operating at a power level where even though they operate at a rather toasty temperature, it is well below the danger point where silicon might degrade, and that'd likely brick it rather than have a slow decline.
Most likely, the cause is RF interference from your neighbors.
Professional athletes, those who've inherited their fortune, and Saudi royalty:
Athletes earned their wealth by virtue of a genetic lottery and countless hours of physical training. Those who've inherited 'old money' have never struggled in their lives and often live in a bubble. The Saudi royalty just dug a hole in the ground and discovered a gold mine.
I think somebody just offered to sell them, 'THE WORLD'S LARGEST biometric database' and somebody said sure, I don't have one of those.
All the equipment you listed is either more expensive, less precise, or not global; and triangulation in 3d space does not really work that way. Using just 2 satellites, you would get a circular area of possible positions, of which 2 would intercept the surface of the Earth and most likely the other would be far from Europe, but you lose altitude measurement and consumer products using the technology will not be reliable outside of Europe. An argument can be made that 3 is sufficient and most GPS devices would be smart enough to ignore the second point ~50K miles from the Earth.
It'll be gone long before then. If you figure that it only costs a few tens of millions for a private individual to launch a satellite, returning requires more fuel and heat shielding, but that's not too much more. Considering that artifacts only increase in value, the cost of "recovery" only decreases, the only thing that can happen to save it from some billionaire with questionable ethics is if there's so much junk up there that nobody even cares it exists.
This study was on women applying for the same jobs with the same exact skill sets as men.
In addition, your statement of most men tend not to marry women who are CEO's, or other successful professionals is completely accurate, but the same can be said about most women seeing as the average male is a high school graduate with an income on the order of 30k a year. The demographic you are referring to of making 80K a year or more represents the top 10% in terms of income, on a statistical basis alone, this demographic likely marries below them regardless of the gender.

Lemme start by saying that I agree.
But isn't sabotage an act of war?
The US seems to think so: http://www.geek.com/articles/news/pentagon-rules-cyber-attacks-and-sabotage-constitute-an-act-of-war-20110531/
And that it justifies military response.

You also need to solve for time. Quartz oscillators aren't precise enough for a fix to within even kilometers, let alone meters.
I hadn't considered that we could use the 4th signal this way... that's really quite brilliant.
