One key point of multiple antenas is that you can have more complex beam shaping. By adjusting the phases (and amplitudes) of each antenna you can build steerable beams by choosing the phases to produce constructive interference in the direction of interest.
This not only allows you a stronger signal between "Bob and Alice" but it allows you to deliver a weaker signal to "Eve" (the evesdropper in all crypto books). If Eve isn't evesdropping, she will probably appreciate not having you contribute to her background noise, since she may be talking to Boris.
This is an interesting link. Is is a gross oversimplification to state that Hartley-Shannon gets 'super Nyquest' rates by using the amplitude to encode multiple bits per cycle? I'm sure that this could be done 'in principle', but in practice, the amplitude is dropping off as 1/r (power drops as 1/r^2) and amplitude is messed up by all sorts of other things (wall, rain, me...). How in practice do people achieve this theoretical bitrates? Do you have to send a 'reference singnal' and use the relative amplitudes?
Can they do all this without linking or modifying the underlying kernel Linux? I assume that they have carefully considered the implications of the GPL. This project sounds cool, but I think I would have chosen something like NetBSD & its less restrictive BSD license.
What you are suggesting will clearly violate the GPL. If you sell a computer with GPL software, you had better tell your users and be able to produce the source code. If you closed-source stuff on top is linked to GPL, you ar SOL.
If you don't like it, don't use GPL code. Contact the author(s) and pay them for a different license, the author can do this but you may not. Being the inovator has its perks after all. But don't link to GPL code in your closed-soruce project. You are viloating the letter and spirit of GPL.
This is exactly why the BSD folks don't like the GPL. They want the users to be free to do what they want to with the source. All they ask is that you don't plagerize their code. If you can live with someone else's name in your source code, then this may be the license for you.
You always have choices, but violating the license should not be the one you choose.
Your plan (sue people) might have worked. Foolishly, SCO decided to sue corporations; and not just any corporation, but IBM. This is almost as famous as 'don't get engaged in land war in Asia' Oh nuts....

Why do you suppose that they care? I would be careful about saying 'as long as oil is traded in dollars'. That may not be very long. Besides, I don't think that the dollar will 'collapse', but it will drop & that will be painful for everyone with stockpiles of dollars. So must of us reading Slashdot should be quite safe.

You are dreaming if you think that the average American IT employee is six time more productive than the average Indian IT worker. As a group, the Indians that I have met are well educated, with significantly better math skills than most US workers. They have excellent English, often with better grammar than us. If we are competing on a 'large coding' contract, it is uncommon to be able to justifly the huge rate difference
However, the dollar is devaluing. This raises the cost of the Indians relative to the Americans. It also makes the Indians richer. This is how the market is supposed to work. We will reach a more level playing field. But is is one that many Americans won't like. Many economists are becoming increasingly concerned with a 'melt down' in the value of the US dollar. Think about this from the view of a foreign banker. They keep putting reserves into dollars, and we keep driving down the value of dollars. Before long, they are going to prefer Euros and Yen for their reserves . If they walk away from treasury bills, we might see the 'dollar melt down' scenario. As long as we are running trade and budget deficits, we are going to see the dollar devalue. So, in a rather perverse way, the policies of the current administration are reducing the danger of outsorucing.
That reminds me of Emacs and Eliza, the software 'psychoanalyst' module. That accepts very unstructured text and formulates a response. That certainly seems to meet the criteria of Claim 1 in this POS patent application. It would do my heart good to have RMS's software be the prior art that overturns this application.
You expect to pick up a phone an call anyone in the US, urban or rural, don't you? When you call a rural person, you are getting a benefit. Why shouldn't you pay a bit as well?
Remember that capacitors store charge and in this case it is at a high voltage. The circuit will hold a charge after being disconnected from the mains supply and can give you a nip. If you are going to work on it then it's a good idea to remove most of the residual charge by shorting the emitter needles to the other end of the ioniser with a bit of wire.
An even better idea is to short the capacitor using a few kOhm reisistor. Discharging capacitors with a wire is needlessly dramatic, at least on a Monday morning.
This seems silly to me. I don't think this can be built into anything smaller than a very large truck. Of course, we have artist that can draw trucks as well as 747, so this doesn't matter for a weapon that is still is fiction. Sorry if that sounds bitter, but I can remember the complete fabricated Reagean-era test showing laser weapons hitting missles; the tests were complete fabrications to impress the press and justify more dollars for contractors.
The envisioned weapon. also uses chemical lasers, so you have a very limited number of shots. I'm guessing here, but I'll bet that it would be cheaper to put everyone into a M1 Abrams, which are effectivly invulnerable to RPG, than to build this sort of laser weapon.
There is no way that a system designed to shoot SAM missles (that have flights of kilometers in open air) are going to shoot down an RPG with a range of a few hundred yards.
This is no more effective at winning the war on terrorism than dreaming about 'real' Starship Troopers. Both are just fantasy, but at least Starship Trooper has Denise Richards as an added bonus.
We want to know all things at all times everywhere in the world? Fine. Do we know what this staring, all-seeing eye is that we're going to put in space is? Hell, no.
My first thought was that we were about to build our own All Seeing Eye. At times, the War on Terrorism does seem like The Battle of Evermore. But its hard for me to see Bush as Sauron or Bin Laden as Gandalf (but the beard and robes help with the later.)
This is more than a joke. In the Gulf war, the military had its own network of satelites. But where did the President go for news? CNN.
There are a bunch of good reasons for the military to have its own mobile infrastructure, but I certainly hope that they leverage existing technology rather than 'reinventing' a family of similar, but not quite compatible, technologies. I hope that we will see that this internet and our Internet are sufficiently similar that inovation can travel in both directions. There have been thousands of RFC's, representing the work of tens of thouands of engineers that went into developing Internet. COTS hardware, existing protocols and BSD-based solutions (I'm guessing that the GPL wouldn't be attractive to the DoD or its contractors) would go a long way to controlling costs and reducing the time to market.
Who cares about BDS, I want to see how many more will start to use BSD. (sorry, it was cheap shot, but you ought to be able to spell a TLA.) If you count OS/X as a BSD, BSD is widely on desktops. It is also widely used as a server platform, even by Microsoft's Hot Mail. All three (Free/Net/Open) of the BSDs have been used in embedded systems (e.g. http://www.netbsd.org/Misc/embed.html)
I'm guessing that the combination of OpenBGPD, OpenVPN, OpenSSH and Asterisk (running on BSD) are going to be a real challenge for Cisco, at least in the home and small to medium business markets. Don't forget that this is the very same team that brough us OpenSSH, which is now so widely used as to be ubiquitous. The convergence of wireless, broadband and VOIP need a flexible router/firewall appliance. Especially now that chip makers (VIA and whatever Motorola is calling its chip division ) are adding RNGs and 'on chip gigabit/sec ethernet' (respectively), it seems like you can build a formidable router with the form factor and power consumption of your typical Linksys home router. For this market, BSD is a natural choice for any manufacture with cold feet about basing a product on GPLed software.
You are sounding like someone that completely ignores the facts. What is the evidence that people wait three years for a heart bypass in Europe or Canada? Show me an article that backs this up. I had more choice in healthcare in France that in the US. Here, some pissant insurance company tells me that they will pay for Dr. X, but not Dr. Y. In France, I simply visted any doctor I chose to. The doctors did compete for patients, but in terms of services. When is the last time you had a house call in the US? You simply cannot get a housecall in the US, because the poor doctor would have to have a 15 lb. medical bag and 40 lbs of insurance forms. The ^%^&% insurance companies deserve to be run out of the country. Medicare has administrative overheads of around 2-3%, but the insurance companies are much higher. Where is the evidence that our current system in the US is either efficient or fair?
I used one of the HoverMow in England. It worked, but was rather underpowered compared to a standard 3.5 HP Brigg & Stratton. I agree that sumultaniously trying to cut grass while blowing it down is not a great idea. The other thing i found was that it tended to drift without wheels, so I was forever trying to keep in on a line.
I worked in France and England and recieved the same healthcare as the citizens. Perhaps things are very different in Canada, but I found the service in England, and especially in France, to be excellent and on par with what I expected in the US. A daughter had a severed finger and the British surgeons did a fantastic job of reconnecting it. It turned out that the surgury team was litterally world class; they were also chosen by Richard Leaky when he was recovering from a leg amputation.
I am very dubious about your stories; they have the air of an urban legend. I tried to google to find a news account that matched your story. The closest google came was the story of a young, uninsured man who died in LA ater being 'dumped' from a hospital. Here is the story: http://www.boulderweekly.com/archive/042403/newssp in.html
So I say give me a reference that supports your story. It is my belief that universal health care with government funding to private physicians is the most efficient form of health care. If you disagree, please prove me wrong; proof needs evidence.
I wonder if they could strip it down and get rid of the hard drive and use a bootable Ethernet card. If you are on a lan with a NFS server running dhcpd, rarpd and tftpd, you can have the computer boot as a diskless workstation. Convince your ISP to run these services and privide users with a home directory. That would be a sweet way to provide a zero maintenance PC to anyone.
