Sensors Gone Wild
tulanian writes "forbes.com has an interesting article on networked, intelligent sensors. It mentions an experiment done by DARPA where several dozen magnetic sensors were scattered along a road and passing vehicles could be identified by their magnetic signatures."
Anybody else try and read this article and not have the faintest idea what it was about?

However, the match is simple and straightforward.
Assume F is the foreground color, B is the background and A is the alpha level([0--255; 0 is pure foreground, 255 is pure background).
Each component (RGB) of the colors must be processed separately, but the math is:
((F.red * (255-A)) + (B.red * A))/255
That wasn't so hard was it? Of course, there are 2 multiplications and 1 division for each component (and three components). MMX allows limited operations (addition, subtraction. multiplication, and shifting) on all 3 components simultaneously, which we will discuss later.
Tha algorithm execution speed can be increased at a cost of accurracy by replacing the division of 255 with a right shift of 8 (which is a division of 256) which can be performed significantly faster. By using a modied Liebenitz series extrapolation, we can compensate for this loss of accuracy, though.
I just heard some sad news on talk radio - Horror/Sci Fi writer Stephen King was found dead in his Maine home this morning. There weren't any more details. I'm sure everyone in the Slashdot community will miss him - even if you didn't enjoy his work, there's no denying his contributions to popular culture. Truly an American icon.
No moderator home pr0n? The title got me all exicted.....
George Duyba Bush, with DARPA backing has passed a law outlawing clothing in the United States. When asked why they wanted to make the US the first all nudist country DARPA replied "Naked people can't be secret terrorists, and we also wanted to see what Britney Spears really has."
