One issue is that satellites see the signal; there's always a little power transmitted into sidebands; and if the sideband lines up with a frequency that satellites use, then they can be in trouble. As WiFi becomes more and more popular this is going to become more of an issue.

Ok Mr Sarcastic, the blimp can have multiple links pointing in different direction; and you can have multiple blimps- they don't interfere if they are spaced a little.
And 802.11b frequency has more capacity than you think- a single link can supply 150 users easily with basic ADSL capacity.
No it really did. Without that car engines run rough as hell; these days we know more ways to avoid premature ignition, but back in those days, there was only one, and he found it.
Without this, motor cars wouldn't have been practical. And frankly the replacements don't work as well- lead protects valve seats far, far better.
HGH in adults helps build muscles. It's a hormone that is secreted during exercise (and about an hour after you fall asleep) that allows a certain set of proteins into the muscles, these proteins allow hypertrophy and muscle repair to proceed, but only if you've worked out in the last few days, otherwise it does nothing good for you.
Professional bodybuilders inject it along with steroids and insulin; and it makes you big and strong when used that way, in combination with exercise and eating lots and lots of food. Atleast it does unless the insulin or the steroids kill you first.
In overdose of HGH causes deformed joints, and atleast one bodybuilder ended up with leukemia that was promoted by his abuse of HGH.
People with naturally high levels of HGH die young by the way, so it's very probably not a fountain of youth, although it may make you feel stronger and better, but you will probably die earlier.
Oh yeah, there's a natural way to boost HGH levels. If you've had no protein or carbohydrates for about 5 hours (doesn't work otherwise), 3 grams of arginine on an empty stomach triggers its secretion after about 1/2 an hour. It lasts for about an hour in the body. If after 1/2 an hour you eat some food, it may be very slightly anabolic but minisculy so. That's probably what they are advertising. If so, it's best taken before breakfast. Oh yeah, and taken that way, it's hardly anabolic at all, and probably can still cause the deformed joints if you overdose.
Yeah, right. Emotional trauma caused by being hit by an 18 meter beach ball moving at a few feet a minute- you'd get laughed out of court.
"And then it popped see, and my voice went all squeaky. My friends looked at me and they all laughed. I was so ashamed. I'm asking for 90 billion dollars in damages."
Actually, Christians are instructed that their body is "the temple of the Holy Spirit," and that we're not to defile it.
Good point. Also, according to Deuteronomy, swearing at your parents must be punished by stoning to death. I call on all good christians to stand up and kill Eminem, and pretty much all teenagers. On second thoughts, nah don't.
More like a kid that plays with the great toy, has great fun, and then has the toy snatched away, and forced to play with cheaper toys.
So it's not really NASA's fault; it's really the government that slashed funding. But NASA has signed up for a mephistopholean pact for funding, that isn't doing it any good at all.
For example, Challenger blew up because they built the SRBs in sections, but they would have been cheaper and more reliable built in one piece if supplied from a particular state; but they weren't because then they would have lost funding from one of the other states...
It's a law in exactly the same sense that Newtons laws are laws; i.e. it's a theory, with good evidence of its applicability to the real world. Nobody seriously ever thought that Moore's law would go on forever- to make a transistor faster you make it smaller, and it's not going to be possible to make transistors smaller than atoms, or atleast not without a radically different technology- and who can say whether Moore's law applies to different technologies?
No biggee actually. WiFi has identical security to the internet.
First you get an account. You can do that using https; https will ensure that nobody nearby can see your CC details. Normal authentication will allow you to check the URL before signing on.
Once you have an account they need to protect your/their bandwidth from theft. They can do that with VPN software; the VPN software will prevent you from connecting to the wrong box.
Remember, there are only 3 (or 4 if you tolerate some overlap) channels available in the US that will work in close range to each other. Add more than that, and speeds start going down. Even more, and packets get lost.
The thing is, bandwidth isn't a fixed quantity.
There are plenty of things that can be done; directional antennas and careful placement of base stations can reduce/increase/control the volume/distance covered.
This almost happened at the company I just left. Somebody sent an email warning of an urban legend. Half the company seemed to send an email (Cc'd to the rest of the company, natch) that said (or a near variety):
"Please take me off your distribution list. Thanks!"
(Rather a LOT of replies in fact....)
Personally, I think that anyone dumb enough to reply to all the people on a distribution list of the people in a large corporation deserved to be taken off the list of the employees the hard way; and in fact our CEO decided to go for multiple rounds of redundancies.
It's good, I've been running it for a month or so, it's currently running at more like 93-97% detection of spam.
Also, I caught it marking two messages from my ISP as spam, but they were both advertisements; so I'm not concerned, in a sense it got it right.
Incidentally, my ISP has spam filtering as well, since I've switched it on a few weeks ago, it has only caught 2 spam message out of several hundred that were caught by popfile(!)
As for being ruseable, hogwash! That adds complexity to the system, as well as refurbishing costs. It'll add weight to the launch vehicle which either translates into a larger launch vehicle (= more money) or lower payload (= smaller market). Not a good choice.
Yes you get a lower payload relative to the same size rocket- so you make the rocket slightly bigger for the same payload, which makes the initial cost higher- but a few times higher at most, and you can aim to reuse it 100x. Refurbishment costs? You don't refurbish after each mission unless you've seriously screwed something up; engines with good margins are needed, unlike the Shuttle.
The problem with that argument is that the "FLIPPIN'" space shuttle always costs the same per launch [1], so that if all you need is to launch a 400kg sat into LEO it's kind of wasteful.
Actually, no, they load more than one payload at one time; IRC the Space Shuttle launched two satellites once; other vehicles routinely launch multiple payloads. They used to launch partially empty most times, because satellites rarely fill the entire cargo bay. But they wised up and that's gone now.
His projected cost per kilogram is about $20K. That's similar to the cost of the space shuttle per kg, but that launches 40 times more stuff. Big flippin' deal.
By comparison, the Russian Proton rocket is down at $2.6K/kg.
But if he really wanted to do something impressive he would design a 2 stage fully reusable rocket. That could probably launch for $0.5K/kg to $1K/kg.
Still, we do atleast have a meter that is defined in terms of the speed of light now, and a second that is defined in terms of vibrations of cesium. That means that we have portable definitions; the old ones were quite difficult to verify, which is why the definition was a bit off initially.
Scrapie in sheep does not seem to be transmissable to humans. Scrapie has been in Britain for hundreds of years, and as far as anyone can tell, does not seem to cause disease in humans.
However, even if the deer are getting scrapie- that doesn't necessarily mean that humans are in the clear- it looks like the disease can change when it goes via a new animal, and it might then be more infectious. (I think experiments have shown this with prion diseases as a group, although not with scrapie, yet, AFAIK.)
It's very difficult to prove that the disease is NEVER found in a particular part of the animal; if it was infectious one time in 10,000 you may not find that unless you did tens of thousands of experiments. I don't think that many tests have been performed.
Also the butchering process can spread the infectious material around some, so probably no part of the animal is entirely safe.
Yeah, nvCJD is also found in certain organ meats though, spleen, tonsils etc. So you should probably avoid organ meat.
But it's a nerve disease, nerves go everywhere in the body, so there's possibly a risk from eating any part of the body; but some parts are far riskier than others.
Still, there's no evidence that this particular disease can be caught by humans, but personally I would minimise my risk, by having the safer cuts of meat, atleast. YMMV.
To be strictly accurate, you can harvest the moon. The moon has every single element needed for 'harvesting' (in different proportions than on the earth, but they are all there), so it's 'just' a question of engineering and chemistry oh yeah and finance.
You don't need to terraform the Moon to live on the moon, or off of the moon.

Actually come to think of it, on second thoughts it was Leviticus. In that case, get on with the killing like any God fearing person should.

The Proton has failed 7 times in about 100 flights since 1991.
But they aren't entirely comparable; Orbital Sciences is a newer vehicle, so it's likely to be less reliable.
Yes you get a lower payload relative to the same size rocket- so you make the rocket slightly bigger for the same payload, which makes the initial cost higher- but a few times higher at most, and you can aim to reuse it 100x.

Now it's exactly 299792458 m/s. Nothing arbitrary about that at all.

How do you think terminator I and II started? Timetravel? Unlikely. Don't take the risk. Just say NO!
