Holographic images absolutely require monochromatic light. To generate the images, you will need to know the wavelength of the light source because you need that to carry out the transformations which will generate the required diffraction patterns. The monochromatic light will pass through the diffraction patterns, like what happens with holograms, and resultant image projected will be the original image.
So, my point being, since we don't know of any other good monochromatic light sources, the obvious answer for the light source is the LASER.
Actually, there may be a reason to implement the algorithm in all 3. The reason being that different layers have different requirements. Implementing the algorithm at the packet layer would optimize packet output. But on the application level, there might be other factors that come into play. For example, you might have some VoIP application that have very different traffic pattern, and consequently may need to be optimized differently. You may not be able to do this at the packet level. Implementations of this algo at various levels with options to switch it off would allow a more flexible implementation. I agree you don't need wireless cards to be designed for it. There's no hardware changes needed.
Now, if you're talking about range increase, I think there might not be any significant increases there. For that, you'll need better hardware, and probably a change in the transmitted power. But within the allowed range, it seems that you can significantly increase throughput.
Well, Computer Science has to do with COMPUTERS. And understanding how they actually WORK, thus, should form part of the Computer Science education. Assembly language, which were orignally designed as a replacement for the machine language written in hexadecimal, is close enough to the machine that it can be used to teach about the way your programs, presumably written in some high level language, is translated into a series of ADD, AND, OR, PUSH, POP, MOV, etc. operations. And this would make you a better computer SCIENTIST, and will let you design better algorithms. How else are you going to design that next generation caching algorithm for the next Intel chip?
That said, maybe someone would write a book teaching people to code in hexadecimal, and describe how THAT is utilized in the processor's FETCH-EXECUTE cycle and translated into a series of electron movements. That aspect of computer architecture should also be something that computer scientists and engineers have to understand.
Yes, you can. Flash card readers abound. If not in US, they're certainly almost everywhere in Singapore, where I am. Some even allow you to read different formats, so you don't have to store different card readers in your house. Now, unless Canon decides to use a different proprietery card format, it seems this signature technique is doomed to be one of those easily hacked "verification" techniques.
A lot of people who buy flash MP3 players jog with them. I wouldn't jog with my ipod. What makes the IPod mini different, such that I would jog with it? It's likely to be equally fragile-feeling.
Applause to HP. Not just to their conviction that SCO dosen't have a case, but also to the brillance of their marketing people. In addition to ensuring that potential customers sitting on the fence don't get scared off by the SCO suit, they're leveraging on a highly publicised case. Thus FREE PUBLICITY!
And the chance they'll win is slim, at the best. So they're not really running a big risk. And if they manage to get enough customers in this period, well, they're betting that the income generated will pay off any resulting lawsuit.
$25,000 to spend every year. Sounds like what is happening in Europe right now. Lots of people are getting social benefits, and because the benefits are so high, there's no incentive to go back to work. The social benefit is at least as high as the minimum wage, and there's no need to pay tax, thus, amount of money you actually get is more. Especially if you try to do a bit of temp job on the side, secretly.
This is what is happening to Germany, and look at what this system is doing to the largest economy in Europe. Imagine then, doing that to the entire US economy. In addition, when people really get all those money without having to exert any bit of effort, do you think there'll be any incentive to create? What do you think caused the communist system to collapse? Nobody wanted to work, since everybody gets the same amount no matter how much effort you put in.
The entire idea of giving people money to spend, for no work at all, goes against the whole theory of capitalism.
Maybe what this is just the second round of attack by the Blaster writers. Use the worm to bring down more systems. Intention? Bring down as many M'soft systems as possible. Who knows, there may even be a virus writing competition out there, and they're trying to see who can infect the most systems.:)
Actually, they're not. What you're talking about is beam-forming, which, is not what MIMO is about. MIMO is more akin to diversity techniques. There're some cellphones with 2 antennas, places perpendicular to each other. By doing this, they take advantage of a free form of diversity provided by multipath propagation, so that if signals polarized in one direction do not reach, there's a chance that signals polarized in the perpendicular direction can reach the phone. We have the same thing here, only much more complex.
MIMO systems rely on very complicated signal processing. Convolutional codes for MIMO systems are significantly more complex, and the complexity increases exponentially with the number of antennas used. Channel estimation and equalization problems are also significantly more complex. They'll probably need quite a fast signal processor to handle all that processing. But I see no reason for them not to be able to do it. The only question is what kinds of costs they'll be able to bring it down to.
Maybe this worm will accomplish what Blaster failed to do: take down the M'soft patch server with DDoS! If it manages to reach critical mass (doubtful), the number of systems trying to reach the server will cause the server to go down, achieving, in effect, what Blaster tried to do.

Sensefilters sounds suspiciously similar to what Prof. Steve Mann in MIT has been proposing. See http://wearcam.org/
