Not so -- ever try to copy a copy-protected VHS tape (VCR to VCR)? You can run the copy, but the color fades back and forth.
Or, as another example, try copying a semi-legal document, like a check. Many times, the word COPY appears in the background when photocopied.
Both of these are copies of "analog" sources, so what's happening? There are interference patters embedded in the analog source of both that are amplified to create distortions in digital copies. The effect is similar to moire patterns that can appear on CRTs, which is why many have moire-cancelling features nowadays.
The copy protection doesn't have to completely prevent copies. It just has to mess the copy up enough to the point you don't want to listen to it or watch it.
In some ways, the most significant feature of the Cordless Presenter is that it relies on the Bluetooth communications protocol for its wireless connection to your PC...Why is that significant? The Bluetooth protocol is likely the most hyped communications standard in recent memory, with thousands of companies joining the Bluetooth industry group.
Uhmmm...so, to paraphrase, it's significant because it's hyped. Apparently, there's no reason for it to use Bluetooth, other than the hype. As many others have noted, you can get products that do the same thing for less than half that price, and that don't use Bluetooth.

YOU REALLY WANT TO READ THIS, ESPECIALLY THE PART ABOUT THE MANDATORY CAR WASH FOR CODEWEAVERS EMPLOYEES...
...snip the rest of the EULA...
OKAY, WE WERE JUST KIDDING. THERE'S NOTHING IN HERE ABOUT CARWASHES. BUT YOU REALLY SHOULD READ THESE THINGS, YOU KNOW. (It's the Beige Honda minivan, if you really insist).
Let me start by saying I'm a private pilot, and of course the radios we use in general aviation planes aren't of the same caliber as those used in jetliners. However (for obvious reasons) they do use the same frequencies.
I had just completed a preflight and ran a radio check on the ground at my small airport. Nobody responded, but I didn't find that unusual, since there are many times there's no traffic in the area and the UNICOM (local airport radio station) is unmanned. Anyway, I announced my takeoff just in case somebody didn't feel like responding to my radio check and took off.
After making a few touch-and-go landings I saw there were others in the pattern, but I wasn't hearing any radio transmissions -- just static. A thought occurred to me and I pulled out my cell phone. Sure enough, I'd forgotten to turn it off. I wasn't receiving calls or anything, but it was still on 'the network'. I shut it off, and the traffic chatter started immediately.
No, it is most definitely a safety issue. I've heard of airliner communication being cut off in an entire airport's controlled airspace because some lady was telling her son that she was going to be landing soon. Needless to say, they were waiting for her when she deplaned:).

When the FM broadcasters pay their license fees, they buy the rights to broadcast the song over a limited area. Therefore, RIAA et. al. can charge multiple times for the same song in different markets.
Obviously, a webcast is world-wide, and the poor, impovershed RIAA can only make their quick buck once. Why should they settle for getting money once when they can get it many times over?

The full-page ad for this story (for me) is for Visual Studio .NET. Looks like OSDN has sold out to the closed-source people! Run for the hills!

One of my favorite bits from the article:

Or I will replace you with a very small shell script.
machines and programs can use a general purpose communication system like this, with no human middleman required
Imagine the possibilities - we could have a global network of computers and other devices that communicate through a common protocol! Oh, wait...
Reminds me of the "TCP over HTTP" April Fool's RFC.
