But yeah, sharks cover their eyes with the nictitating membrane (or roll their eyes back if they lack a nictitatinig membrane, like the Great White) when they actually bite, so they don't rely on their eyes for the final attack; but before that final attack they do rely on their eyes (as well as their other senses).
You missed the memo. It was in the We The Geeks NASA G+ hangout today. Some folks actually care about the issue enough to put their money and time where their mouth is and thus are actually doing what you propose.
Thank you for that link!

I think you may be committing at least two errors here:
1. Confirmation bias #1: Thinking that "GW alarmists tout every earthquake, every drought, every flood as proof of global warming". Global warming affects the climate, which affects the weather - generally, in making it more extreme.
Heck, when Mount Penatubo in the Philipeans (SIC) blew, it put more of the same pollutants that the Climate Crazies worry about, (Sulfur dioxide, Carbon Dioxide, Carbon Monoxide, Nitrides and just plain dirt) than the entire Human Race had done during the entire Industrial Revolution up to that point.
The Mount Pinatubo eruption in 1991 emitted 42 million tonnes of CO2. Human emissions in 1991: 23 billion tonnes of CO2.
Volcanoes emit about 1% of the amount of CO2 that humans do, per year.
Okay, for the past five years or so I've experience some of the most frigid winters. We had an extremely cold winter. Followed by a winter with record snow (4 ft in two days). Followed by a year with a mild winter but a huge snow in fall and a late frost in April. Then this past winter we've had snow flurries on about 1/2 the days. And now, in the middle of may we had a frost wipe out my second planting of sweet potatoes and peppers.
Neither the warhead nor the missile would gain much in either cost or simplicity of manufacturing from having a 3D printer available. Any part that could be made by a 3D printer is not a part that's hard to make or acquire by other means. The manufacturing challenges of both missiles and nuclear weapons lie in areas where 3D-printing is of no help whatsoever.
Technology is fun and all, but I sure hope we'll never reach the point where people can print stuff like that in their basement.
3D printing isn't magic, and it's not a sci-fi replicator. It can only work with one material at a time, and that material must currently be a (rather brittle) plastic. It is unlikely in the extreme that 3D-printers will ever be able to work with metal due to the temperatures needed.
So there's no need to Chicken Little just quite yet.
What's the difference between "perl" and "Perl"? "Perl" is the name of the language. Only the "P" is capitalized. The name of the interpreter (the program which runs the Perl script) is "perl" with a lowercase "p". You may or may not choose to follow this usage. But never write "PERL", because perl is not an acronym.
Though Perl is not officially an acronym, there are various backronyms in use, such as: Practical Extraction and Reporting Language.
From Learning Perl, 2nd Ed:
Perl is short for "Practical Extraction and Report Language," although it has also been called a "Pathologically Eclectic Rubbish Lister." There's no point in arguing which one is more correct, because both are endorsed by Larry Wall
Either way, typing the name of the language in all-caps is wrong.
Pray it's the Chinese... and it's not SCORPION STARE.
Although if you know what that is and don't have GAME ANDES REDSHIFT clearance, I'm afraid you're in for a change in work environments - hope you like British bureaucracy!
They're talking about capturing a 7-meter asteroid. Those already impact the earth roughly once every two years. And when I say "impact", I mean "break up in the atmosphere and do little to no damage to things on the ground".
* Energy before atmospheric entry: 1.63 x 1013 Joules = 0.39 x 10-2 MegaTons TNT * The average interval between impacts of this size somewhere on Earth is 1.9 years * The projectile begins to breakup at an altitude of 65500 meters = 215000 ft * The projectile bursts into a cloud of fragments at an altitude of 41400 meters = 136000 ft * No crater is formed, although large fragments may strike the surface. * The air blast at this location [1 km away from the impact point] would not be noticed. (The overpressure is less than 1 Pa).
If Israel continues on this course, it will be reviled like South Africa was during the apartheid era.
In many places, it already is.
Most of the EU, for instance, seem to think that the Israeli are being quite unreasonable with the land the UN gave them in 1948. Sure, it's a game of I-slap-you-because-you-slapped-me-because-I-slapped-you ad nauseam, but one of the parties slap rather harder than the other; often unreasonably so.
But they have the backing of the US, and as long as they do, nobody's going to protest too much. If they didn't have uncle Sam condoning their every move, my guess is they'd be struck down as a rogue state in a matter of weeks.
It wasn't supposed to be a contradiction, it was supposed to be educational. Of course I'm aware those battles were fought before the French revolution. That's not the point. The point is that the military the Americans are so fond of mocking is the one that helped them create their very nation.
Mention Ticonderoga, Yorktown, or Chesapeake to any American military buff and they'll get something proud and patriotic in their eyes - but it was really the French that carried those victories. That's something they choose to forget - hence the "arrogant" part of my post.
Some further tidbits about the French military: Of 125 major European wars since 1495, the French have fought in 50, more than Austria (47) or England (43). Out of a total 168 battles they've fought since 387BC, they won 109, lost 49 and drawn 10.
That's quite the record, wouldn't you say?
FWIW, I'm neither French nor American. I'm just tired of the chest-pounding, the short memories, and the ungratefulness of it.
Woody Guthrie also said this little gem: “This song is Copyrighted in U.S., under Seal of Copyright # 154085, for a period of 28 years, and anybody caught singin it without our permission, will be mighty good friends of ourn, cause we don’t give a dern. Publish it. Write it. Sing it. Swing to it. Yodel it. We wrote it, that’s all we wanted to do.”
We already do that to a great extent. The United States in particular gives away more aid in food, medicines, and money than anyone else in history. We do it on a massive scale.
In absolute numbers, the U.S. is indeed the single largest aid giver in the world, giving more than double than the next two nations (U.K. and France) put together. As a percent of GDP though, it's actually Norway. The U.S. comes in at number 19 when counted that way (0.21% of GDP for the U.S, 1.10% for Norway).
In fiscal year 2010, the U.S. government allocated the following amounts for aid: Total economic and military assistance: $52.7 billion Total military assistance: $15.0 billion Total economic assistance: $37.7 billion of which, USAID assistance: $14.1 billion
Add to that somewhere between $10-$30 billion from private sources (foundations, organizations etc).
Grand total, somewhere around a tenth of the military budget:
In fiscal year 2010, the U.S. government spent $711 billion on the military, almost exactly as much as the next fourteen biggest spenders together. 41% of the total military budget of the world is the U.S. alone.
I've read that book; it ends with them banding together and declaring themselves the sovereign nation of Luna and start chucking rocks at earth until we stop going after them. Then the singularity takes away our interest in going to the moon at all.
Or perhaps that was the different space stations and the nation of LEO/GEO. Either way, there were crustaceans involved somehow. And the singularity.

Fresh water freeze's at 32 degrees.
It does not, you bumbling hack. Fresh water freezes at zero degrees.
Seriously, leave Burma and Liberia behind and get with the program.
he should have added h) readability, I need to read it back to myself in 6 months time and understand it.
Perl is only as (un)readable as you make it; if you write readable Perl code, you won't have any problems reading and understanding it 6 months later.
But yeah, you can write unreadable Perl code - but then again, is there any language in which you can't?
I think you may be committing at least two errors here:
1. Confirmation bias #1: Thinking that "GW alarmists tout every earthquake, every drought, every flood as proof of global warming".
Global warming affects the climate, which affects the weather - generally, in making it more extreme.
2. Confirmation bias #2: Thinking that just because you experience cold weather there is no global warming.
The longer, colder, more snowy winters are actually an effect of global warming, counter-intuitive as that may seem.

Chicken little.

Perhaps not, but it could still cause a lot of damage
Not really. 7 meters is a *lot* less than 100 meters when we're talking about asteroid impacts. It would break up in the atmosphere.
Here's a more detailed look at what would happen, I'll highlight the relevant parts:
* Energy before atmospheric entry: 1.63 x 1013 Joules = 0.39 x 10-2 MegaTons TNT
* The average interval between impacts of this size somewhere on Earth is 1.9 years
* The projectile begins to breakup at an altitude of 65500 meters = 215000 ft
* The projectile bursts into a cloud of fragments at an altitude of 41400 meters = 136000 ft
* No crater is formed, although large fragments may strike the surface.
* The air blast at this location [1 km away from the impact point] would not be noticed. (The overpressure is less than 1 Pa).

That video... sure isn't action-packed.
At first I thought I was watching a scene from 2001: A Space Odyssey.
Like 2001, this video is interesting but slow :)

I doubt it's a coincidence the French haven't won a war since the French Revolution (if you consider Napolean a continuation of the Revolution...)
These battles might be of interest to you arrogant Americans:
1758 Battle of Carillon (a.k.a. Battle of Ticonderoga)
General Montcalm and his vastly outnumbered French forces are victorious over the British.
1781 Battle of Yorktown
French forces, allied with the Americans, are victorious over Cornwallis and his English army.
1781 Battle of the Chesapeake - September 5th
France, coming the aid of America's George Washington, defeats the British in a strategic victory.
Without the French military you mock so, you wouldn't even have a country.
