Please, someone correct me if im wrong, but my understanding is its like having a red, and blue ball in seperate bags. You throw one ball (in its bag) across the room, then open the other bag. The open bag is blue, you now know the red one is across the room.
It's more like having two balls, both half-red half-blue, in separate bags. The balls contain a magnet that causes them to align: when one is red-up, the other is blue-up.
Then you shake the bags, open one, and pick out the ball. If it's red-up, you'll know the other ball will be blue-up, and vice versa.
At first glance this may look the same as your model with the full red or blue ball (a so called hidden variable model), but the statistics differ from real entanglement (which includes superposition of states).
In the first (classical) model FTL information transfer is impossible because nothing is actually transferred. The ball was blue or red to begin with, and opening the bag doesn't change that.
In the second (quantum) model FTL information transfer actually does occur (with entanglement, the magnet alignment in the model occurs slower than light obviously). But the observer can't choose what this information will be: picking a ball out of a bag will result in a random color. And the other bag will then contain a ball in the opposite but equally random color. You can't pick the color, so you can't choose the message/information.
Statistics from experiments have shown that the second model is the correct one, and that entanglement and the FTL state transfer are real.
Most companies don't have radio (which has commercials) in their offices anymore, because it is considered public music and they need to pay for it.
Sabam even tried to argue that, since truckers are at work while driving, they should pay for the music they play (radio) in their cabin (considered the work floor).
When your screen protector gets too scratched up or too dirty, you just peel it off and put a new one. If the same happens with this plastic button layer, I don't think it will be replaced so easily (it's connected to the electronics of your phone).
Maybe a screen protector on top of the button layer would be possible, if it's sufficiently flexible and resilient at the same time. Most protectors today are made from fairly rigid plastics, so those wouldn't work.
Well, if you want OS VMs inside the browser, there is also Linux in Javascript (http://bellard.org/jslinux/), or Google Native Client . NaCl is particularly impressive, since you can use it to run old games inside your browser (http://www.naclbox.com/).
Not the parent, but they're talking about VMs that are integrated in the browser, such as a EcmaScript/Javascript VM, Flash VM (ActionScript: Flex applications), Java VM (applets),.NET VM (Silverlight applications), etc.
Nowadays the term VM is used a lot for visualizations of whole OSes (VMware and others), but the original meaning was a virtualized cpu that could run some sort of bytecode.
No. The regulations are for tracking cookies. Cookies for normal operation (storing the state of the site) are still allowed without explicit permission from the user.
if two atoms are entangled, changing the state in one affects the other, right?
In a way, yes. But not in a way that most people think this works.
In order for two particles to be entangled, there has to exist sufficient uncertainty about the entangled (quantum) property, for example the polarization angle of a photon.
You could entangle two photons in such a way that their polarization angles are always at a 90 degree angle (simple case, but other correlations are possible, like 40% chance it will be 30 degrees and 60% it will be 60 degrees -- just making up numbers here).
As long as they are entangled, you have no way of knowing what the polarization angle of each photon is. Once you measure the angle of one photon, you will know that the other one will be at an 90 degree angle once someone measures it too.
The reason you can't use this to transmit information FTL is that you can't control what angle you will measure. So in this regard, you cannot "change the state in one". The person/sensor at the other end will just measure a stream of photons with random angles, and they'll only know of the entanglement after you send them your results (slower than light) to compare.
The interesting part is that the (random) angles of both photons are in superposition until you measure one, at which point they become fixed (wavefunction collapse). So in that regard, measuring does change something. The reason we know this, is because the statistics of the results differ from the classical case where both photons had a fixed but unknown angle to begin with (but the numbers match perfectly with the quantum/superposition case).
There already is a firewall in android, it's built in the kernel, and just needs a frontend.
Personally, I use DroidWall as a frontend for iptables. Is free and works great.
The funny thing is, I use it mainly to restrict data from leaving my phone, since a lot of apps nowadays insist on having internet access, and can't be trusted with my personal data. A nice side effect of this is that is also blocks ads.
which is a good thing, because the source code was lost when my old laptop died
Try http://java.decompiler.free.fr/.
It usually produces compilable source code from class files. For non-obfuscated code the sources often look exactly like the originals (minus the comments). Also, it can convert a whole jar to a source zip at once.
Most of Mozilla Foundation's income comes from Google. Seems like a huge conflict of interest...
Why would that be? Mozilla's product is a web browser. Google's product is an advertisement network. That they also make a "competing" web browser is just a side effect of that.

So that would be no vandalism at all then...

One of the things I like about current generation smart phones/tablets is that they're very resilient to scratching, using a hardened glass screen.
This looks like a soft rubbery layer on top, so my guess is that it would be quite vulnerable to scratching and tearing.

Lol. The "world" meaning the US of course. And being in the US, you'll probably get sued anyway...

Woops. I somehow completely missed the percentage sign. I stand corrected (and a bit embarrassed).
No it's not. The parent is correct.
c=3*10e8 m/s , so 1/1000 of that is 3*10e5 m/s , or 5 zeroes.

That's incorrect. The Earth's magnetic field is at most about 60 microTelsa.
1T is an enormously strong field, see here.
