I hate NAT myself, don't get me wrong. However, I believe that today NAT is viewed as much of a security feature as well as an IP-conserver.
I'm not sure that NAT orovides a lot of security, but it certainly means that a firewall somewhere HAS to be involved in communications between the target machine and the outside world.
The torque is balanced because the amount of momentum due to the air exhaust from the tips of the rotors is equivalent to the momentum that the air exhaust transfers to the rotors.
In a "normal" helicopter, momentum is applied to the rotors from the engine without any balancing counter-momentum. Thus the need for the tail rotor.
Jenni was definately a "pioneer." I believe she was the first person to do the 24/7 homecam thing in a serious way. And I think her existance helped to drive a lot of reality-based entertainment, including influencing the writers of "The Truman Show". She also was an early blogger.
My wife and I worked with her to produce "The Jennishow," a series of streaming video shows about her crazy life, which changed the course of our company, and without it there never would have been a "Geeks in Space" Slashdot radio show.
We had a lot of fun filming "The Jennishow," including going for a ride in a private plane of a fan, JenniCon with the "top fans", and another fan leading us to the house at the end of the Blair Witch Project. It was a trip!
There are two directions with DTV. #1 is getting more channels in the additional bandwidth. For instance, many PBS DTV stations run a 4-channel multiplex during non-prime-time. This way you aren't stuck with just kids shows during the day, they can also run local programming or adult educational shows.
#2 is High-Definition. Some programming is really much, much better in HD. Some may not be.
This is why Netmeeting and other H.323 solutions should be thrown on the trash heap.
In this day and age, the vast majority of people with high-speed connections are behind NATed DSL & cable routers. If your solution can't handle NAT, it is almost useless.
Right now, I consider Yahoo Messenger the only realistic solution. Sightspeed is nice as well, especially for higher-speed connectivity, but costly.
I work in a typical broadcast installation that has seen a lot of changes over about 10 years. Each time, new coaxial cable was laid under the raised floor. First it was composite analog video and analog audio, then composite digital video and seperate AES/EBU audio, now 4:2:2 component digital video with embedded AES/EBU audio. Not to mention the addition and subtraction of channels and services, installation of new video switchers, routers, etc.
Today, there is 1 foot of solid coax under the entire raised floor. They try to pull out abandoned cable, but it generally is near impossible to do much of that while keeping the place on the air.
The problem with reprocessing right now is that Uranium is incredibly cheap out of the ground, as demand flatlined in the 80's since few new nuclear plants went online. Economically, reprocessing might not make sense for decades even if many new nuclear plants come online.
"Black" in the minds of most Americans is "of African descent." There are plenty of people from South Asia who also have dark skin, yet would not be considered "black" by most Americans. That is the problem with trying to define a race by genetics.
Show me a genetic marker that applies to 80% of a "race."
I can think of a few markers that are highly concentrated in a few races (Sickle cell ~10% of Africans, Tay Sachs in ~30% of Ashkenazi Jewish), but none that are found in 80% of a "racial" population.
Moreover if you went after something like Tay Sachs, it would also take out a large number of Arabs as well as Jews. Of course, I suppose that didn't stop Al Quaeda in Turkey...
With a technology like Digital Fountain, you can continuously send out encoded data using multicast, and once clients receive enough packets (equal to the size of the file plus a slight overhead), the clients can then recreate the original file.
More simplisticly, you can "carousel" your data out through multicast by sending out packet 1..2..3..4..5 then back to 1..2..3.. etc. again, but if anyone misses a single packet they have to wait the entire length of the file to receive the final packet they need. Technology like Digital Fountain avoids that.
Sony is actively pushing the Blu-Ray format. There is already the HD BDZ-S77 Blu-Ray HD recorder/player devices being sold in Japan.
Blu-Ray can hold 23GB on a disk, but more importantly it can have very high-speed data transfers, and the pro Blu-Ray devices even have two heads for faster transfer.

CiteSeer is great! I've recently been using it to examine reliable multicast over satellite and MPEG-2 frame-accurate stream splicing and editing.
The problem is that CiteSeer is about tapped out on computational resources. Over the last few weeks, it keeps complaining about being too busy.
I wish someone like Google would partner/buy CiteSeer so that it has the resources to go on. I wouldn't mind a few text ads in there, it would be a highly-targetted technical audience.
The challenge here is that you can't have a genetically-targetted race-killer, because race is a social concept and not really a genetic one. Besides the vagueness of race (such as "white" or "black" when both are full of incredible genetic differentiation), even "racial" phenotypes do not always stem from identical genotypes.
There are plenty of examples of people from different races who are closer genetically to each other than to many others of the same race.
Now an individual or family target, that is a different matter...
A lot of the early solar power satellite discussions mentioned rectennas of very large size (~1km diameter), such that the microwave power density at any one place is fairly low. This reduces the needed gain (~size) of the transmit antenna as well.
You might not want to live your life under the rectenna, but should the beam go astray for a while, no one would be in immediate danger.
Of course, the issue there is whether or not you would be better off with 1km diamater solar power array on the Earth rather than a rectenna, given that sun illumination per square meter is much more, and will warm your skin. Of course you need to store power for rainy days/nights.
A friend of mine received and email last week from a large, popular, managed hosting provider saying basically:
"Oh yeah, the RHL you are running, it won't be supported any more. If you'd rather run a supported OS and have bugfixes and security issues handled, move to RHEL, and pay us more money per month."
The US has been shifting from a manufacturing economy to a service economy little by little for 50 years. Services are now what makes the US economy tick. The US manufacturing sector share of GDP has shrunk from 25% to 16% since WWII, despite amazing rises in US exports & GDP, as well as the fact that the US has a lower unemployment rate than China or most European countries. The US does not need to "defend" manufacturing. Only high value-add manufacturing remains in the US, and we do fine.
While China's exports have grown dramtically recently, Chinese imports from the US have been steadilly growing each year as well.
Trust me, the world will be a better place when everyone has a Western standard of living. Chinese GDP per person has quadrupled since the 70's, now at $4,400/person/yr, China now has the second largest economy in the world.
Of course, there is that whole Lenninist government thing. I believe it will go away, and in fact, most people would argue that Beijing's control over the country is falling away rapidly. A big change will happen in China in 20 years, especially as GDP per person approaches $10,000/yr.
The interesting thing about this method is that it is solid-state rather than some concoction of lasers and ultra-cold gasses.
Demonstration of conditional gate operation using superconducting charge qubits

Following the demonstration of coherent control of the quantum state of a superconducting charge qubit, a variety of qubits based on Josephson junctions have been implemented. Although such solid-state devices are not currently as advanced as microscopic qubits based on nuclear magnetic resonance and ion trap technologies, the potential scalability of the former systems--together with progress in their coherence times and read-out schemes--makes them strong candidates for the building block of a quantum computer. Recently, coherent oscillations and microwave spectroscopy of capacitively coupled superconducting qubits have been reported; the next challenging step towards quantum computation is the realization of logic gates. Here we demonstrate conditional gate operation using a pair of coupled superconducting charge qubits. Using a pulse technique, we prepare different input states and show that their amplitude can be transformed by controlled-NOT (C-NOT) gate operation, although the phase evolution during the gate operation remains to be clarified...
If anyone is interested in setting up "video portals" between places like Internet cafes, wired coffee houses, art galleries, colleges, etc., go ahead and contact me.
Video projectors are easy, it is the audio that would be the biggest challenge. A combination of traditional sound reinforcement techniques (directional mics) and active de-echoing would be required to make it work well.
BTW, Germany now faces a government deficit greater as a percentage of GDP than the US does.
The difference between Argentina getting deep into debt at the US going deep into debt is that the US has a track record of near continuous economic growth. The gloabel investment community believes that the US economy will continue to grow, tax revenues will continue to grow, and that the US government will always pay off its bonds and notes.
Dollars are demanded worldwide to purchase key US exports (Windows among many others...) and to invest in US companies which have been excellent investments over the long term. Moreover, as of late, the Federal Reserve has been an excellent manager of a stable currency.
Plus, the US government has been exceedingly stable over a very long period of time (125 years or more). China may have 10% GDP growth now, but would you take a bet on whether there will be some kind of massive revolutionary change there in 10 years? Or whether the Communist government would do bizarre things like nationalize foreign investments, etc.?

Yeah, the government needs more money and are better at determining where you money should be spent. Riiiiight
Economic theory states that simple wealth redistribution is economically neutral. It neither expands nor contracts overall wealth. The biggest problems is where the government destroys wealth with taxes, through the production of things of no value.
Fortunately, a lot of the US governments actual spending these days in on things like Social Security which is simple wealth redistribution, and Medicare, a signficant percentage of which actually is of value to people. But not all of its spending is economically neutral, true.

Many HD-ready sets have an RGB 15-pin Dsub for computer displays.
OTOH, if you have an HD STB, you can use almost any multi-sync modern monitor to watch HD as well.
