It is my understanding that with quantum cryptography.. it's not that the message is unbreakable, but that it is not possible to intercept the data without leaving a trace.
So you can break it, but everyone will know you did, ie: you can't eavesdrop.
Let's pretend for a moment, nevermind how, that nobody can extract digital information from a CD anymore.
As everyone says, we will just make high quality analog recordings, and then turn those into the compressed music format-du-jour.
And people won't care. Digital copies will still be an issue, because once that digital master is made form the analog output, we can make perfect copies of that the world over.
But the court fairly easily determined that that particular McDonald's coffee maker had the water much hotter than normal; they did measure them.
It was found that McDonalds knowingly served it's coffee on average 20 degrees hotter than other restaurants. Approximately 185 degrees F (that's 85 degrees C). Whether this is hotter than your hot plate at home isn't relevant.. it's other drive through restaurants.
And it's also a myth that the lady was driving... (not that you mentioned it). She spilled the coffee while stopped, and she was the passenger.
at that temperature, third degree burns happen in just over 2 seconds.
As someone else pointed out, the problem being demonstrated was that in the original (with semicolons included, and both statmenets the same, ie: i initialized within the statement), vc++ would complain about i being reinitialized on the second one... when it shound't, as i is already out of scope.
Americans are very much interested in ultrathin tiny pcs.. if they are either a) cheap or b) really fast.
The problem is, they tend to be a fair bit more expensive than the average normal notebook, and not as fast or feature rich, and not all that much smaller.
This is what many people don't realize. The coffee was not simply hot coffee.. it was *extremely* hot coffee; the kind you can't drink until it cools quite a bit; the kind that, when spilled, caused instant third degree burns.
This was not a minor coffe accident with some 1st degree burns.. it was coffee being served way over the normal temperature that coffee is served at, with no warning.
Who cares? The Internet is a bunch of networks hooked together. Whether those networks are chiefly isp's networks, or community networks it doesn't matter.
Yes, there can be interference.. but it's also about power. As long as one signal is significantly stronger than another, it should prevail... This is also why there are multiple channels... so you can try to avoid overlap.
You can't extend the range of 802.11b to miles.... not omnidirectional anyway... you can in a certain direction, yes.... but the higher the gain, the narrower the 'beam'.
In the case of your neighbor, chances are his AP will be what his cards will see, and yours is what your cards will see, because the signal of the local ap will be significantly stronger.
Yeah.. except it should be clear to anyone that, theft aside, Trillian and the like provide an application that is beneficial to those who use it. I wouldn't be surprised if they patented the idea.
I think ultimately it will have to go this way.. either that, or things will be regulated on a per-protocol basis so much taht eventually new networks based on new protocols will emerge, and we'll start over.
ultimately, the internet will move towards usage fees, yes, but they will be based on only two things:
Volume over time and priority.
The application will not matter; only the type of traffic you want to use (ie: do you need a priority on bandwidth or latency or what). You will pay for QOS, nothing else.
The internet is not supposed to be anything; it's just the result we get when we all use approximately the same set of protocols and adhere to roughly the same standards; we've ended up with a bunch of networks hooked together that can more or less talk to each other freely.
Nothing forces anyone to follow any standards other than the desire to communicate and gain maximum benefit from that network.
To stay within FCC regulations, there are rules about the effective radiated power from an antenna on this stuff. IT's not safe to say that you can just throw any antenna you like on it, and it's okay; if you exceed certain gain levels, you are outside the rules. This differs from country to country of course; I know that you can get more effective power at distance out of 2.4Ghz ISM in the US than you can in canada, for instance.
Speedstep is a fairly easy thing to research; they make a point of saying that laptops have it.. it's quite clearly labeled as such.... And a speedstep enabled machine will let you run it at full clock all the time if you want to, easily. For instance, my laptop has a nice button on the windows system tray that lets me flip it between different cpu settings.
In this case, the laptop does NOT have speedstep, it's a desktop processor, and the laptop is basically hardwired to run it at half speed when the AC is disconnected, the user has absolutely no way to change this behavior.
It's not a common behavior, and one I think most readers here would not even know about until they looked in detail at those specific models of laptop.
No, Mhz is not an all-encompasing speed indicator. but it's still quite releveant, and the difference between 1Ghz and 500Mhz is rather large, especially when you are forking out several thousand dollars.
Actually.. and I'm surprised you don't know this...
It's running out of a former military base UNDERNEATH hudsons bay... the entrance of the 500 mile tunnel to the base is somewhere in the canadian shield.
Strange that they let some university types in there...

It's all time and effort wasted.

What is wrong with the second example? i would have to be declared previously of course.... but what's wrong with it?

What they are saying is "Given that NOW we are telling you we have the patent, from this day forward you have to pay us licensing fees"
You can't collect damages for past use of a patent if the parties didn't know about it.
Who cares?

Technically illegal?
As you said, it depends on the EIRP.
It may or may not be illegal.
And eirp regulations for the 2.4Ghz ISM band, especially in the US, are quite reasonable. I don't have the numbers in front of me....
Yeah.. except it should be clear to anyone that, theft aside, Trillian and the like provide an application that is beneficial to those who use it.

Their product is excellent.
Not a secret anymore now, is it?

one of the main factors barring adopting voip in many areas is the fact that it doesn't work over tcp.
Yes, I understand fully why tcp is not the best protocol for voip.. however....
NAT. So many ISPs now, especially in poorer countries, use NAT. And not even good nat... the kind of nat that really only works well with tcp.
Thank you for visiting the American Airlines web site titled "aa.com" (the "Site").
Well, I didn't visit 'aa.com' . I most definatley visited 'www.aa.com'... so right off the bat we have a bad contract.

Except it's being stolen from a regulated utility.. which I believe ends up in the feds lap.
You could be blueboxing telephone service, and only make $10 in calls, and still go to prison.
Maybe because theft of service from cable companies, or phone companies is considered a serious crime?
