not necessarily. Plants use it, and release waste O2. someday a genetically engineered plant matter may be useful for an oxygen factory. And we can always find a use for spare carbon.
Most of the NSA's IT stuff is contracted. For their actual employees, NSA uses the same GS scale as every other federal agency. A GS-12 computer scientist working for the NSA gets the same pay as a GS-12 working for the department of agriculture studying the composition of cow flops in Idaho.
There have been many articles all over the place about people spoofing google by making tons of pages that link back to the real page they want to boost
weather, for one, you can't really point to any place in america that doesn't have a pretty high risk of a heavy storm/wind at some point of every year. just watch the weather channel display how the jet stream moves sometime and you'd change your mind quickly.
also the fact that to be geostationary it needs to be at the equator.
The US Navy and Air force would be quite able to protect it.
Well, them. anyone who wouldn't use the first one as a crane to put up the second one has to be at least mildly retarded. Why build 1 when you buy 2 for twice the price? And the second/third etc would actually be cheaper, since you launch them practically for free.
What good is spending 350-400 billion a year on the military if you only spend 20 billion a year on public schools?
Easy. There's 270 million Americans. Most of them have already graduated school. So throw out a rough guess of maybe 50 - 75 million kids in school for that 20 billion dollars to look after.
On the other hand, there's about 6 BILLION non-americans out there. It should be fairly obvious that it costs more to babysit 6 billion sub-standard people than it does 50 million superior Americans.
Our kids can be taught to behave with simple measures like writing "My butt is not a work of art" on the chalkboard, or detention, or extra homework. Those sub-Americans aren't as sophisticated as our noble children, and tend to require more direct forms of discipline such as the careful application of Cruise Missiles, satellite guided precision strike bombs, and new solid state aircraft mounted 100kw Laser weapons.
If the commie bastards in that lesser, barbarian china, and the peace loving democratic society of the Republic of China, can ever learn play nice together, or if the backwards and violence prone theocracies of southwest asia ever realize there is no santa claus, boogie man, etc, and get with the whole 20th century thing (hell if they even caught up to the 19th, I'd be impressed) then maybe we wouldn't have to beat the living hell out of them as much and could devote more of our true American Greatness towards more worth matters, like falling attendance at Major League Baseball games. Seriously, that IS the national pastime, and it's unthinkable that dealing with the inferior citizens of lesser nations should distract us from it.
the point he's trying to make is that the money you pay to see a movie at that point goes directly to the local theater operator, and NOT the mpaa slime. supposedly.
you have it kinda backwards. the idea in the p2p, decss etc fight is to prevent the government from imposing restrictions on people's behavior at the behest of an industry with lobbyists and FUD to fling around. The idea behind the paranoia/big bro shit here, is that people don't want the government to mandate a way to watch over how people drive, at the behest of an industry with lobbyists and FUD to fling around.
Both are examples of the same kind of issue. You don't want The Man scanning everything you say on IRC, post to/., etc, reading your hard drive for w4r3z or an mp3 that isn't accompanied by a signed, notarized, registered certificate of approval every time you turn on your computer. (I assume so anyway, there's always the slim possibility that there are some sheep here who think that's a great idea) Why would it be any better for the government/insurance companies/"whiplash" lawsuit enthusiasts to be able to track every time you sped up a bit (to pass some old woman) made an abrupt lane change (to save your life from some stupid whore with 7 kids screaming in the back of her SUV while she put makeup on her cell phone) or slammed on your brakes too hard (because the stop sign was overgrown and couldn't be seen from a reasonable distance) and paint you as a reckless and horrible driver and thus revoke your license, or raise your rates, or sue you for hundreds of thousands of millions of billions of dollars?
The idea that "it's in your car" so the information contained in the black box cannot be used against you is faulty. The data requires specialized hardware and software to be read, thus you wouldn't be incriminating yourself via this device, your friendly neighborhood body shop or mechanic or insurance agent would be subpoena'd to do that for you.
unless the airport was in the habit of turning away properly documented passengers purchasing tickets under their own names, with valid drivers licenses and carrying nothing illegal or particularly dangerous
first of all, you moron, without the us military being on the island 60 years ago, you wouldn't have been bombed, you would have been invaded and siezed. go ask a few koreans how that trick works. the primary difference is, native hawaiian women tend towards being overweight, and hawaiian men are slow and tend towards laziness, so unlike the koreans you wouldn't have made good whores and slaves. you wold probably have been suitable for being marched off a cliff at gunpoint though.
second, you moron, a 90% popular vote in favor of statehood sounds like something that was really twisting arms out there. whatever your non-existent "world court" was babbling about, the US for some reason, let your worthless island in, and now we're stuck with you.
thirdly, you moron, as a previous post pointed out, without the US you pretty much will die. There are damn near a million people on those rocks with pretty much no identifiable sources of income aside from tourism and leeching from the us government. Little things like all your food, drugs, spam, toilet paper, refrigerators, school textbooks (however little good they seem to do you), cars, tires to put on them, gasoline to put in them, a stable, world respected form of currency to buy everything with, laws, airplanes, roads, building materials, are you getting the picture yet? comes to you courtesy of the shipping facilities on the west coast of the US. Take this all away, and you go back to living the way you were found, a bunch of wild savages living hand-to-mouth and cudgel-to-brain. Please don't tell me you've bought into the disneyland image of the great enlightened culture you try to sell to the tourists. Before the english found you and started educating the people there, stacking a few rocks on top of each other and hooting at people while waving stick-spears was about the height of advanced civilization there.
You have a million people packed into a bunch of islands with exactly 3 natural resources. Rocks, pineapples and Fish. Rocks are common, and you will not be able to earn enough money to feed your million overweight people by exporting rocks. Fish are common, and you will not be able to earn enough money to feed your million overweight people by exporting fish. You may be able to feed a million overweight people by catching all those fish....until your waters become depopulated and you have destroyed your precious little environment. Pineapples can be grown elsewhere, and almost certainly are. I just don't feel like looking right now. While pineapples may provide you with some sort of income, it would probably be difficult to grow them effectively without the fertilizers and pesticides you get from the US, and the money and regulations the FDA and USDA provide to ensure they're safe for consumption.
Finally, you moron, our military bombs our lands. Plain, boring lifeless piles of volcanic rock. Not much point in bombing water, is there? Our "mainland corruption" (just out of curiosity, are you one of the idiots who called into the radio stations on september 11th last year saying the WTC problems were "mainland crap" that weren't important to you) can't possibly drain resources from the islands, as there are no resources to drain. The reverse, hoever, is quite obviously true, as your island consumes many resources that could be much better used in America. As far as draining money from the islands, without the US you would have no identifiable form of currency other than cracked seashells and shiny bits of coral. It is the Hawaii that drains money from the United States, by leeching hard earned money from tourists who fell for the vast amount of overstated hype and bullshit about how beautiful and perfect everything is out there. If you, moron, want to see a drain of money, Please go ahead and try to secceed, and start counting the cashflow when all our tourists decide not to bother getting visas and passports, and spend their time on the beautiful beaches and islands of Florida, parts of California, the Gulf Coast, Puerto Rico, Guam, and the Caribbean islands, all of which are US states and/or territories, accept US dollars happily, are significantly cheaper than your overpriced crap, usually have friendly, polite, happy people, and beaches more than 20 feet wide with fifty thousand people crowded onto them.
Although bitching about how horrible the US is is the official pastime out there, you really should think about what you're talking about. While I know that isn't something you're used to, it does have benefits. Hawaii needs the US a million times more than the US needs hawaii. If you go, no one here will notice, or care. A few people will have to change their vacation plans, but they'll be happy to do so when they get to St. Johns, USVI and spend a few days on the beautiful beaches, with some of the best snorkeling in the world (vastly superior in every conceivable way to Hanauma bay, that really is a dump) , enjoying some fine domestic rum. Until California can pick up the slack in the pineapple industry (they can grow everything else...) maybe a few people will have to suffer to eat their ham without pineapple for a few months. The military could give a shit, most of them are disgusted with hawaii, and bases in America and on Guam can provide the support they need.
Now finally they have got an incentive to polish that English, German or Spanish.
Actually they always had plenty of incentive to learn as many forgeign languages as possible. For example: "french military" and "history"
That's the whole point of using UCAV's. if someone shoots them down, it isn't a very big deal. And given the way we tend to do war upon people, there won't be very many 3rd world flunkies with anything to fly larger than a kite after the first day or 2. And if someone did decide to take off and fly after something like this, then a human fighter pilot or a surface to air missile would ask them to please stop bothering us. As for the AI, what i described requires nothing of the sort. An autopilot and an if/then routine. This isn't anything new, the Aegis weapons system has been designed with the capability to automatically fire weapons since the 70's. When armed it can attack anti-ship cruis missiles incoming without asking for human intervention, which could take too long to be useful, with the soviet mach 4+ Shipwreck missiles. A dumb target like this just needs to have a radar/radio detector set to report certain frequencies, if that frequency is reported, then hit the fire button.
because it isn't. You can write a bill. you can send it to a sympathetic congressman. If he thinks it isn't full of shit he can present it to the appropriate committee. if they think it isn't full of shit they'll scrap it. If they think it's utter nonsense, they'll tack on a few amendments that say something about abortion, restrict gun rights, and give welfare mommies in nebraska a new car, and they'll send it to the floor of the house. and the house votes on it, and presents it to the senate. a few months ago there was a popular link flying around about someone who proposed a bill to the kentucky state legislature to fund a submarine to patrol the river and torpedo casino riverboats.
anyone can do that
you can write a bill yourself and send it to your congressman to be presented. welcome to the republic.
what you thought those laws just sprung out of thin air on the floor of the house to get voted on?
The A-10 can carry most likely 3 times the payload of this plane and do so with (for aircraft) some serious armor.
And as far as being a better air superiority fighter than anything in service, There still has been nothing come up with yet to replace the F-14. They're still incredible, and can still sweep the sky of (insert enemy air force name here) from farther away than they can even be detected. Mach 2.4 with the ability to simultaneously attack 6 targets over 110 miles away (technically the range of the missile depends on the speed of the enemy aircraft, as they can be expected to fly closer while the missile is en route, and they are unaware of the launch) is nothing to ignore.
The JSF is a good plane, yes, but it isn't the best plane in the sky at every single function of military aircraft. Or even any of them. It just has greater versatility, which can make missions a lot easier. Once a carrier full of these flying en masse has wiped out your entire air force, they can all land and come back as bombers. It's the stealth that sets them apart. Yes an F-14 may be able to do damn near everything the JSF does, and better, but if we ever need to fight someone with any military capapbilities worth not laughing at (which is actually a pretty damn short list anymore....umm...maaaaaybe china?) that is going to help keep things in the right balance.
The right balance of course, being everything on our side
Subcontracting. All the defense bigshots do it. Boeing's design wasn't chosen but there is always a chance they will get to build sonme under contract if lockheed finds itself swamped with deadlines and orders from the military and EU
jamming a specific frequency isn't hard If you know what it is and you have the right equipment and that equipment is in the right place. and you can crank out more power than the signal you are trying to jam and you STILL are basically fucked if, like search radars used by the military, the command/control link is set to shift freqs on some complex algorithm. or even a simple one really. although movies may have you believe that you can push a button in front of you on your Star Wars (tm) land speeder and "jam" the entire electromagnetic spectrum, in practice it takes a wee little bit more than that.
The US can conceivably do it but often we don't really bother. The infrastructure would be a nuisance. Jamming radar is easy and useful. Jamming comms is a real pain in the ass. Even if some magic antenna were created that would radiate immense power to jam all possible frequencies the enemy might use, then you have the slight problem of 1. microwaved technicians and 2. you just screwed yourself out of any chance of communicating with your own people. In order to be effective, you have to have a signals exploitation system/team/whatever. They have to find and identify the frequency you need to target. And they need to do so in time to have it actually do any good. Then you need to have the jamming equipment to deal with that frequency band. And you have to be able to broadcast towards the target with more power than the base station you are trying to block is capable of reaching the target with. Sending a puny signal to block a strong one obviously wouldn't work. You also need to have your jamming antenna last longer than 2 or 3 seconds. And the US Military has electronics warfare people who take almost child-like delight in smashing other peoples antennas with Anti-Radiation Missiles. Just ask any Iraqi who pushed the "send" button on anything larger than a walkie-talkie back in the Persian Gulf Ass Kicking Festival. The reason he won't answer you is because he's dead. And that was over 10 years ago. Our missiles haven't been sitting around getting arthritis, they're faster, more accurate, blah blah blah. You could even have a nice big fat UCAV with a halfassed AI and a whole pile of HARM missiles, doing nothing but flying circles and transmitting on the same frequency, just to get someone to turn on the jammer. A transmitting antenna is screaming its own position to a HARM missile, they really don't even need a targetting system.
The US Navy still teaches officers celestial navigation. This is still actively practiced on ships, junior officers plot the stars even when all systems are funtioning, to keep in practice. Exactly for the reasons you mentioned. Gyrocompasses can fail, so can satellite receivers, and if a freak fire or damage as a result of combat just happens to knock out the nav systems, at least the ship can still get home without sailing in circles until they run out of food.
