I hope you're being sarcastic since your sig seems to suggest that you might not be an idiot. If not, then here's my rant.:)
How exactly are those bunch of idiots going to "obliterate" us exactly? Fly a plane into a building and kill a couple thousand people? I don't exactly see us being invaded by Al Qaeda anytime soon, ala Red Dawn.
What actual real lasting effect did that have on our country beyond the self imposed insanity we unleashed as a result of that? Destruction of our civil liberties? Ruining our economy with a completely pointless and meaningless war that killed thousands of innocent people and incited even more hatred against the US? We did all that to ourselves. When are you people going to understand the best revenge is living well? Let those fucking morons live in a cave somewhere in Pakistan with their backward fucking medieval ideas and try to hurt us with their pinprick terrorist attacks.
Uh yeah, they were shooting at them 1) with a gun 2) which generally doesn't cause massive collateral damage 3) during a declared war 4) at an enemy in uniform 5) while on the battlefield. Let's see which of those things is the same as the current situation? Oh right, not a goddamn thing.
Yeah I'm a game developer and have been trying to get Apple to make this API public to no avail. We have a game on the DS that uses wifi hotspots as part of the gameplay. We really wanted to do an iPhone version but weren't able to because the API to find hotspots is private.
Having been personally involved in coding several of several ports mentioned in these comments, to and from a wide variety of different platforms, the way it usually works is that the publisher will outsource the development to company like the one I work for. The schedules are always very aggressive and tight so unfortunately you know what the end result of that is. It's not like we're trying to make a bad product, we do the best we can given the constraints. Personally I find the job very rewarding and fun and intellectually challenging, even if the end result isn't always that great. I get to see a lot of code from a lot of different companies and it's quite interesting. The challenge is, basically, here's a big mess of code of uncertain quality, get it to work on another platform in 6 months. I *always* give the publishers realistic timelines, which they ignore and we still wind up having to do it 6 months. The only way to get a real quality product on multiple platforms is for the original dev team to develop for all those platforms themselves, or give us enough time to do the port. A lot of times we'll get the contract a year or more after the original game has shipped, we've only occasionally be able to develop the ports simultaneous the original development.
Yeah this poor guy could only afford a nice house and a plane. Just imagine, without that terrible law, he could have been able to afford a two engine plane and a slightly nicer house!
Ah yes it's time again to break out the old phase vs group velocity explanation again. There are plenty of things that can go "fast than light", but repeat after me, you cannot transmit *information* faster than light. There are many concepts in our current understanding of physics that you just take to be inviolate like conservation of energy, momentum, speed of light. That's not to say we those concepts might eventually be superseded but as a general rule of them any theory that doesn't follow them is probably pseudoscience and wrong. Physics develops from what proceeded it, from Newton to Einstein to Quantum Mechanics to String Theory, and those conservation laws always held. Perhaps reformulated in a different manner to stand for different things but they still held. You don't need to know the details of how a proposed "perpetual motion machine" may work to know that if the crackpot building it says that it violates the law of conservation of energy then it doesn't work.
Actually I just had a better idea, how about a reboot of the franchise during the movie itself! Or maybe do it Rashomon style where the origin story is told over and over again from different points of view.
Sounds great to me, that's the best part, right? Of course that second Hulk movie totally missed the point by cramming the original story into the opening credits. Let's reboot every comic book movie each and every time!
Looking at the wiki page describing PDF it may not be Turing complete as it only includes a subset of Postscript which excludes if and loop statements.
Well I certainly understand that, but why aren't hackers targeting Notepad then? That's definitely a software monoculture.;) How much more complex is it parsing ASCII than a PDF format? Is there anything inherent in the PDF format that makes software implementations inherently more buggy, other than just the simple fact it's a more complex format? Or does Adobe just suck? I can understand something like JPG where you have compression vs a simple uncompressed image format which should be trivial to guard against buffer overflows.
Could someone please explain to me why I have to be worried about $#! document viewer compromising my system? WTF Adobe!? Glad I don't have to use it to read PDF's anymore. Thank you OS X for builtin support.
Introducing asymmetries has long been know to produce real particles from the vacuum. If you could actualize this you could then accelerate the electron and positron to fire them off in the same direction, giving your apparatus a push in the process.
You know, I think a lot of us here understand basic physics well enough (and even have degrees in said subject) but are still trying to understand how this is any different than throwing photons out of the back of a rocket through some other means. Yes it's an interesting effect but what practical advantage does it offer over any other method? This is still just a reaction drive if I'm understanding this correctly. You throw some momentum in one direction to get an equal amount of momentum in the other direction.
Yes that's correct, virtual photons. A photon is the carrier of the electromagnetic force and is the quanta that makes up the field, so any electromagnetic interaction can be thought of as an exchange of virtual photons, that is, photons that appear spontaneously out of the vacuum. http://en.wikipedia.org/wiki/Virtual_particle
Well technically the car is losing a slight bit of mass because of the energy change, but that's not relevant to the propulsion, a car isn't a rocket. The car is pushing against the earth and transferring that momentum to the earth.
OK from the article they're "changing the momentum of the electromagnetic fields in a quantum vacuum". Basically that just means they're throwing photons out the back. That is still going to decrease the rest of mass of whatever it is that powering it. So what's the specific impulse of this method?

Uh yeah, perfect analogy there buddy. How about this one, I leave my car fully gassed and running for my toddler to get in and drive around.

Everyone knows facts have a liberal bias anyway.

Denken Sie bitte an die Kinder?
Pensez svp aux enfants ?
Pensi prego ai bambini?
Please think of the little wallabies eh mate? Now let's throw another shrimp on the barbie.

Apologies if the French is totally wrong, just ran it through babelfish. :)

Oops, I meant to type *origin* stories. Doh!

None. Come up with some new ideas already.
Naw, I'd prefer they do a show set in his Culture universe.

How soon was it before they decided to graft another head on the foxes? I hear Russian scientists were all into that sort of thing.
Yes they do, E/c^2, or p/c if we're talking flashlight rockets.
Technical nitpick, a flashlight rocket still loses mass equal to E/c^2, or p/c (the momentum of the photons divide by c).

And to add to that, "real" photons are what make up electromagnetic waves, which are propagating changes in the electromagnetic field. http://en.wikipedia.org/wiki/Electromagnetic_radiation
