Hardware based doesn't seem to mean much anymore. It seems to me that hardware based used to mean purpose built hardware to do only one task. Now it means "we put a tiny computer in the hardware." It's only slightly more secure than doing things like encryption on the OS because your just moving the work from one generic processor to another. If some malicious programmer knows what you are doing he/she could just as easily take over that "tiny computer in the hardware" as the CPU.
From what I understood it had to take off and go supersonic very quickly to heat up the hull. Once the hull was warm enough it had to refuel immediately.
Sorry, my point is that the F-117 can carry the JDAMs and the laser bombs where the B-2 can only carry the JDAMS (as I understand it, because the aircraft requires a laser emitter for the bomb to follow). The question is, how much does the military rely on the laser guided bombs?
Also, there are surely times when a tactical strike aircraft is more what you need than a strategic bomber. My point is, JDAM gave the B-2 tactical strike capability. The F-117 has laser guided bombs, which, as far as I know, can hit a moving vehicle where the JDAMs would be less effective. But the JDAMs do have advantages. From the wikipedia article cited above:
Limited visibility of the ground caused by smoke, fog, dust and cloud cover limited the employment of precision guided munitions.
Research and development of an "adverse weather precision guided munition" began in 1992. The first JDAMs were delivered in 1997 with operational testing conducted in 1998 and 1999.
From what I can tell the F-117 can destroy whatever it can see, and the B-2 can destroy whatever a spotter on the ground can see.
It seems to me that the B-2 fills many of the rolls the F-117 did. The F-117 may be smaller and slightly more maneuverable but since the development of GPS guided bombs the F-117 seemed to be outdated. The B-2 also has the advantage of a longer range and larger payload.
Don't be confused by the name. The F-117 is a bomber not a fighter. As far as I'm concerned the F-22 is the first true "stealth fighter."
Sheriff of Rottingham: This is a stealth catapult, we've been working on it secretly for months. It can hurl one of these heavy boulders undetected, over a hundred yards, completely destroying anything in its path.
Prince John: Wow! How's it work?
Sheriff of Rottingham: It's rather simple. You get one of these heavy boulders, put it here where I'm sitting, and then pull on that lever.
Prince John: Like this?
[John pulls the lever and flings Mervin into the air]
Sheriff of Rottingham: AAAAAAAAAAAAAAGGGGGGGGGGGHHHHHHH!
why are they called "stealth fighters"? They're actually a tactical bomber, and so far as I know, they don't have any method of attacking another air craft. I suspect they called it that to make advisories confused about the aircraft's capabilities.
The stealth fighter was really more of a proof of concept of what stealth technology could do. The plane sacrificed quite a bit in aerodynamics to be stealth capable. It was a subsonic vehicle and, despite what it's name suggests, it had no air-to-air combat abilities.
Although it was revolutionary at the time it first came out, keeping this aircraft in the skies would be a disservice to the taxpaying public.
They leaked fuel until the heat caused by friction (like on the space shuttle) made the panels fit together by thermal expansion. The fuel was also very difficult to ignite.
When I was in school we had some wide screen monitors that could be rotated 90 degrees so you could fit more text on the screen at once. However, I don't think it can be adapted very easily to a laptop.
If I'm remembering my electromagnetism theory correctly you would have to be moving through the magnetic field pretty quickly. The question is, "Is the moon traveling at a high enough velocity to generate enough electricity to sustain the moon base?"
Remember, earth has it's own magnetic field that we experience every day. However, the earth's rotation is not fast enough to generate a significant amount of electricity. In my college physics class we calculated that if you ran a piece of wire from wingtip to wingtip of the Concorde, the amount of electricity generated by its movement through the earth's magnetic field on it's way from New York to London could make a piece of toast.
but in terms of efficiency nothing beats a low speed direct drive engine. The big advantage of a Diesel-electric drive is that the engine speed is not a proportion of wheel speed. If you always drive on level roads, with your cruise control set at 60 MPH, and never stop, you are more efficient with a mechanical drive. Once you vary speed and load you have a big advantage with an electric drive because speed and load can be varied independently. This advantage usually outweighs the losses of the electric transmission.
Reports state that the quake was felt as far away as Chicago. Speaking with everyone I work with, it was only felt by people who live in tall buildings above the 5th floor. I live on the ground floor of my building and didn't notice a thing.
I suspect that this isn't because the professors are sick of students playing games. It's that the students can do research so rapidly during class that it makes the professor look like an idiot in front of the whole class. A lot of law school requires thinking on your feet. The internet allows research on your feet too.
Second, Storm synchronizes the system time of the infected machine with the help of the Network Time Protocol (NTP). This means that each infected machine has an accurate clock.
My fiancee's computer never has the correct time. I guess that rules out the cause as being storm worm related.
I tried using Googlephone yesterday and I found it to work quite well. It had some trouble understanding my speech but it got the job done and it didn't sound like Stephen Hawking. Sure it's only a computer substitute for directory assistance but I don't see why this can't be adapted for use by the blind.
I'm assuming the plants would be grown inside a pressurized building. The great breakthrough with this study is that the soil in the building would not have to be brought all the way from earth. The amount of soil would be heavy and require massive amounts of fuel to get it there. The results of this experiment suggest that we would only have to bring bacteria, air, and water.

It's simply security through obscurity.

As I understood there was something to do with the environment the aircraft flew in that required it to use the mechanical gages.

Correction:

proving once again that spell check isn't fool proof.

they were the same aspect ratio as an HDTV.

Couldn't they just make the moon base be a giant Faraday cage and not go outside for six days a month?

Good point, mod up
How about updating the images. They must be five years old. Things change, buildings get built and torn down.

Not only that, Hydroponics also makes the whole experiment pointless.
Mod up please, The above author just proved the research pointless because hydroponics and Aeroponics can grow plants without any soil at all.
