If the signals are encrypted with a predetermined key it will be susceptible to replay attacks
Replay attacks could be prevented by making the messages spacetime specific - GPS systems rely on very accurate timekeeping, so it should be easy enough to make GPS units throw away messages that came at times that disagree with the message's own internal time (which could not be altered without breaking the encryption).
I fail to see how this could be successfully replayed under those circumstances.
4995 is still a heck of a lot less then a full time DBA
Um... how does paying for the license get around needing a DBA? It's not exactly an either-or.
I'm not the parent poster, but it seems to me that the argument goes along the lines of "if you hire someone expensive to do a job, why not spend a small amount more to allow them to do it properly."
I hate it when I see expensive, skilled employees being forced to use outdated technologies in their tech-sensitive jobs. It seems like such a waste.
Okay, I know this is Slashdot, the bastion of "everything should be free now, gimme", and I for one highly dislike the idea of in-game advertising (unless it's funny), but seriously, what is the reasoning that goes behind the idea that if you pay for something, even just a little bit, that somehow it's immoral for a company to take product placement/ad money.
To me, in a "free market" (yeah right, but that's another post) as long as the company does not hide that it has this advertising in it, then you know what you are paying for when you buy it. 1337 game XYZ that you've waited 6 years for has ads you have to watch in it? Boo hoo, it's just a game, if you don't want it don't buy it.
There's no "right" to quality entertainment products. If you don't like what big labels are doing, support small labels, shareware people, or open source. There's also 30 years of great games out there right now, many of which you can play for free! Sure most have crap for graphics, but today's games will be considered almost as bad 30 years from now.
I was going for funny by pointing out the ridiculousness of someone named "Assmasher" being afraid to be crass, but ended up getting Insightful. Only on slashdot...
Okay so I'm replying to this rather late, despite enjoying the post when the article first came out.
Is there a way to tell which, if any, HDTVs and/or DVD players on the market employ wavelet based techniques?

What kinds of positions are there available at Akamai? It sounds to me like there are some really serious applied CS problems being solved there, and that sounds exciting.
I'm planning on moving up to Boston in a month, as I have friends up there and job prospects, I'm quite curious as to how/why Akamai is expanding.
If a planet has an atmosphere, it's possible that life on that planet will cause it to be in a non-equilibrium state (chemically speaking). This is something that would not be too hard to detect from earth (i.e. lots of oxygen in an atmosphere won't last long w/out life). Our efforts should therefore be focussed on what we can, in principle, detect.
Could silicon-based life inhabit the lithosphere of a planet? Maybe so. Could there be life deep inside stellar cores or gas giants? Why not? But we don't know how to detect these kinds of things (unless they make a huge change in the structure of their environment). We're best off looking for signs of life that we understand and can identify at a large distance, rather than observations that could be easily explained without invoking life.
If "eminent domain" was "fair market value" then people would be happy (no, eager) to have their work appropriated. Why aren't drug companies lobbying for federal money to buy their great cures? Maybe it's because the government would never pay what he cure is actually worth to the company?
Right, because the knowledge that any "really important" cure will be immediately appropriated by the government will have no negative effects on companies spending time and money to develop those kinds of cures in the future.
The alternative to income taxes would be federal sales tax, which is generally considered to put an undue tax burden on people who don't make a lot of money...eg, the rich man and the poor man buy a loaf of bread, and the 30 cents tax on the bread that goes to the Fed means nothing to the rich man, but means a lot to the poor man.
A specific proposal for such a tax, FairTax "fixes" this problem by giving *everyone* a basic living stipend (calculated to offset tax), such that in effect everyone's *absolute basic necessities* cost nothing, and *everything* else is considered (rightly, in my opinion) as a luxury. Most so-called "poor" people in the US (yes, that includes many below the poverty line!) actually have a ridiculous amount of stuff compared to people in 3rd world countries (e.g. cable TV (?!?!!)). Those that happen to use common sense with what "little" money they have frequently have even more.
This plan has plenty of issues with it, and there is an interesting article at the Jews For The Preservation of Firearms Ownership (I'm not gonna touch that one) homepage. And to think seven mere years ago, I did not find taxes the least bit exciting!
Why do governments tax anything in the first place? It's because public services cost money, and that's a convenient way to of collecting said money (and because they are usually the ones that have all the guns).
I personally don't see how this is any different than, say, taxing sales of Beenie Babies, whose value (like so many things) is also largely virtual.
As a registered Libertarian, I can't say I'm too happy with trends towards new taxation (internet sales tax, etc), but this type of thing may be inevitable as more and more people make significant portions of their income in online environments. Maybe this should be targetted only at assets that can be legally converted to cash?
Something tells me your intent to buy the Macbook Pro wasnt put off by the lack of the right mouse button. Firstly the Macbook Pro doenst come with mouse because it's a notebook. Secondly, OSX supports just about any USB 2 and 3 button mice.
Am I the only one who actually uses the trackpad on notebooks instead of external mice? Occasionally (for gaming) I might pull out a mouse, but I've always disliked the lack of a second mouse button on my Powerbook 17" G4. And yes, I know you can use the control button, but that is simply not the same.
I was bored one day in high school, so I took a TI-85, the GraphLink sonic rangefinding sensor, and a turntable, and made a surprisingly functional sonar unit. Some simple calibration, and modification of the control program to display results in radial graph mode was all it took to show objects, etc, on the screen.
Seems a little silly now, but it was the first time in my life I felt like an engineer.
IANAP (though I do have a BS in Physics), but I've been tossing this idea around for a few years and thought I'd share with slashdot:
Cosmic rays contain energies up to 10^20 eV (source: Oh-My-God Particle) whereas the LHC will only have an available energy of 10^13 eV (14 TeV, source: LHC). It seems to me that 10 million times higher energy will be difficult to achieve (read: impossible without at least Type I Civilization level technology). What if we could, instead, harness the power of these freely occurring cosmic rays?
My idea is simple to say (but very, very hard to do): erect a series of stations in space that use superconducting electromagnets and plasma to create extremely huge magentic fields that can focus large amounts of high energy cosmic rays into a very small volume where they can impact on a target. A spaceborne lab would study the results of each impact. I admit that there would not be *that* many events, and the focussing fields would have to be very, very far away from the lab to deflect the rays meaningfully, but it seems like it might work.

There's a glitch in the Matrix! They must have changed something - quick, everyone get to a telephone ASAP (no cells, that's cheating!)
The result, joked neurobiologist Björn Brembs from the Free University Berlin, could be "world robot domination."
Well, I guess this means that I, for one, welcome our new Free-Willed Robotic Overlords...
I fail to see how this could be successfully replayed under those circumstances.
It's never going to happen, but if Sun chose to release the code as public domain, then it would be compatable with *everything*.
The US is big and sprawling. Socialism doesn't cut down CO2 so much as high density (thus enabling mass transit).

I choose to believe in free will, and if there is none, then you can hardly blame me, right?
Deja vu is caused by a glitch in the Matrix - this would affect all senses, not merely visual. Am I the only one that thinks this is really obvious?
