When you fly as much as I do, you see these things on a regular basis. I "opt out" of the scanner machines every time. There is very little credible evidence that these machines are NOT harmful, and even if they were - do you think the TSA and our Government would ever admit that? Its all a crock.
I am continually surprised by how many people do not know that they can opt out.
And if I sell one of these DVD's that I took into the 'magical' Kiosk say at my tag sale...can the purchaser now do the same? What if I buy a used movie? Am I SOL? (that's a rhetorical question because we are ALWAYS SOL when it comes to DRM...)
I always wondered why many states require passenger cars to pass through strict emissions tests, however it is perfectly OK to have trains, dump trucks, buses, and large vehicles spew columns of dark black diesel exhaust into the sky....
In a world where online connectivity is not only the norm, but absolutely REQUIRED for modern games (WoW, CoD, etc)....we will only see this trend shift more towards the service based model.
Of course, it doesn't hurtthe game manufacturer to insist you buy a base copy of their game (for $60 or so) and THEN basically force you to subscribe to the service going forward. This puts more money in their pocket even before the game is available as well as keeps you hooked. We see this paradigm shift in games such as Call of Duty - MW3 where the "ELITE" service is an additional add on, just as the map packs that everyone just has to have.
AFAIK however its only used for digital transmission where you can do a lot of signal processing. I don't think it would work well with analog - look what happens on AM at night.
However SFNs are used with the DAB digital radio system in europe.
All transmissions are inherently analog in nature. The phrase "digital" only refers to the processing before and after (companding etc). AM refers to a modulation scheme. FM also refers to a modulation scheme. FM is more reliable and has better consistency than AM, however both are analog technologies.
GPS transmitters on the space segment all share the same channels and it's not a recipe for a disaster. Your GPS receiver works just fine listening to all those satellites all jabbering on the same channels. You engineer the whole system for it. Let's put it this way: wireless microphones are not anywhere near state-of-the-art in digital data transmission techniques. Extraterrestrial links are where the state of the art is at, and mostly has been, too, for a good while.
That may be true for GPS, however you must remember that GPS signal they are multiplexing on the same frequency certainly is not tasked with carrying real-time, high fidelity audio that one expects from wireless microphones, radio, TV, etc. They are simply using a time-based location receiver to determine positioning.
Any engineer worth his salt will tell you that there is "no free lunch" when it comes to transmitting high fidelity audio in real-time over the electromagnetic spectrum.
What about the issue of multipath, where one wave inverses the phase because its reflection arrives at the antenna slightly delayed from the original direct LOS (line of sight) signal?
I work with wireless microphones and deal with spectrum issues on a daily basis. With the shrinking spectrum, this would be extremely good news if it actually was feasible and practical in the real world. As it stands right now, two transmitters operating on the same frequency is simply a recipe for disaster.
oh yeah, first!
As long as this isn't similar to previous claims of Cold Fusion in tupperware and the Emperor getting new 'clothes' then it may be something to get excited about.
nothing close to what you asked for.
Asking for anything in the public sector is much like negotiating a salary, or selling an item: Ask for the world, your original offer will be cut back to a percentage. Of course the instructor knows he doesn't need supercomputers to run software X...he just knows that if he aims high, he will get closer to what he knows he needs.

want mine nowwwwwwwww!

This is especially true for cops who use their hand held mobile phones while driving. It's ironic and sad that many cops do this and then turn around and issue tickets for the same offense in those states which have laws prohibiting the use of handheld phones while driving.

Sounds like we should give them the same image as one reproduces by sitting on the copy machine, sans trou.

If you weren't too thrilled about Oxygen, then I suppose you could grab the remote and change it to the History Channel or something more stimulating.
If you warp a drive to destroy data, isn't it just easier to wipe it with thermite?

I first read the head line as "what the EFF?"
1 Scrap current Ubuntu GUI
2 Enrage current Ubuntu user base
3 Create 'new' GUI nobody has seen before
4 GOTO 1

Doesn't Skype and AT&T sometimes have this feature built in already?
