Bohmian mechanics states that the particle is riding a wave, and only ever passes through one or the other slits - depending on its initial conditions -, but once the particle and its wave hit the slit, the wave indeed passes through both slits and interferes with itself, and ultimately modifies the particle path accordingly. So the difference may seem trivial, but it is quite huge - one is possible, the other is not; one leads to contradictions, the other does not.
You're not making any difference - as you can see by the way your result agrees with the QM one. If you want to declare that the particle creates a wave and that wave passes through the slits and then alters the particle's trajectory, you can, but Occam's Razor will eat you - it's more true to simply say that the particle behaves as a wave, unless you have an experimental way of separating your particles from their waves (which I know you don't, because that would give rise to an experimental violation of QM, and there isn't one).
There is no proven violation of causality. As for non-locality, the Bell inequalities say nothing, but entanglement can cause what seems to be non-local behaviour - and it is measurable. We won't really understand entanglement until we understand decoherence, and that's still an open problem.
What the Bell inequalities tell us is that reality really is fundamentally nondeterministic - quantum mechanics can't possibly be a "layer" on top of some more fundamental, underlying, deterministic system.
Single electrons produce single dots. It's only after you dump many electrons through that you get a pattern
Yes, but the point remains - you get an interference pattern, even though there was only ever one electron going through at a time.
You can call it a "wave trajectory" if you like, but a wave (an ordinary, water or (non-quantum, for the moment) light wave) would go through both slits at the same time - just like an electron does.
Can't you pretty much do that already with KDE? Konqueror will act as a shell to contain any KPart, and most KDE applications provide a KPart, so you can easily have your word processor, music player and web browser be simply different tabs in the same shell (and while it doesn't replace your window manager, you could use konqueror's full screen mode to get the effect you want). (And it definitely already provides your networking in an app-independent way - you can use kioslaves to open a file via e.g. sftp, using any kde program).
This won't be a popular opinion but lynching would never have been the problem it was if the targeted population hadn't been deprived of it's right to keep and bear arms as a result of racially motivated gun control laws. Would you go into a community and drag someone out of his house to lynch him if you knew all of his neighbors had shotguns and were willing to use them?
You're damn right I would. Even in the absence of laws, which population could better afford to own guns? Having firearms be legal always favours the criminals and the rich.
Your socks wouldn't come under hate speech laws anyway. We have harassment laws, and they seem to adequately cover the kind of things you're talking about; I see no need for hate speech laws on top of that.
I hate when people include extraneous links in their posts, as if they think I'm too dumb to find something on the internet myself.
Worst is the people who write something and make the phrase a link to its wikipedia page - "not only do I think you're too stupid to know what this means, you're so thick you couldn't even put that exact phrase into wikipedia".
Anyway - addressing the more important part of your post: I think there will always be manned fighter and attack craft, for the same reasons that there will always be grunts on the ground. The machines and the technology are cool, but they can't occupy a territory, they can't impose their will on the occupants of a territory, and in fact, they lack any will to be imposed.
That doesn't seem something terribly important in the air. You'll always need grunts on the ground, sure, but I can easily see a future where the only combat aircraft are unmanned drones - mostly fighting other unmanned drones, and supporting the grunts on the ground.
you seem to be making this whole thing more confusing than it needs to be. You're shipping a proprietary application. Therefore you can't use GPL code in it
But he'd expect to be able to use LGPL code in it, i.e. the LGPL version of Qt. And he can't. Which is somewhat confusing.
I've never worked on Qt, but doesn't the boost signals2 library now offer a superior signals and slots implementation in standard C++?
It's entirely possible, if by "standard C++" you mean very extensive use of templates. Qt's signals/slots could have been written that way, but Trolltech took the pragmatic decision to sacrifice standards compliance for practicality - moc gets you readable error messages, and doesn't have the long compile times. (Also remember that compiler support for templates was a lot worse when qt was started than it is now; I suspect you couldn't have written signals2 five years ago)
I find the Gentoo way better: you have everything you need at your fingerprints, you have a detailed readme, but you also have a nice script that can just build the initrd for you, and even install it.
This is a general phenomenon, and why I switched: Gentoo has all the clarity and simplicity of Slackwhare, but also good, coherent dependency management, an even better init script system, and more control over the details of your packages.
As a European who occasionally reads the newspapers in question, I just find this exceedingly hilarious. I've never seen a single US paper that could be called anything other than extreme right.
Ok, you're right - for specific, specialist workloads, non-x86 chips can get you more bang for the buck, since that only requires one particular application to be tuned for the system. And I believe Cells are being used in scientific computing - but there most of your time is spent running LAPACK, so again the optimization effort is pretty focussed. But to make an alternative architecture as effective for general desktop usage would require dozens or hundreds of programs to get such attention, and the margins on desktop systems are small enough that it's simply not worth it. You speak of parallelization of desktop applications, which is indeed a worthy goal, but if history is any guide it will take decades to happen, if it ever succeeds at all (personally, I think after a few years we'll see a renewed focus on clock speeds, as it emerges that getting engineers to make faster cores is easier than getting programmers to parallelize well).
Is Cell worth selling as a processor for specialized markets? Sure, and that's already being done. But for general-purpose desktop machines, I really don't see it.
The State of Utah can ban playboy from bookstores (and they have), but they are not any obligation to inform the other 49 states or the U.S. Congress about this change in law. It's called sovereignty - Utah does whatever it pleases within its own boundaries.
So as a business owner wanting to run a bookstore in the US (let's say an internet one, so the idea of customers from multiple states makes sense), I have to separately investigate the laws of each state, and I have to do it myself, because getting all the states to publish their laws in a single place would be a violation of sovereignty?
I'm surprised to hear that the UK has less power over its own laws than does Utah
It's not like this gives the EU any power over the law - they don't get any option of refusing to accept the notification. It's just that they have to be notified. How is this any more a surrender of sovereignty than requiring the laws to be written down?
Mandelson isn't an MP; he lost that job due to corruption. And while in the very best of British traditions there's no formal requirement that government ministers should be elected MPs, it's sort of expected.
What about crystals like diamonds, rubies, sapphires, etc.? Those are worth a *lot* more than gold by mass.
Only "natural" ones, and only because of artificial scarcity. If you found some of those in space, I'll wager de beers et al would run a campaign to declare them "not real diamonds/rubies/etc.", the same way they've done with the ones we produce in labs.
The statement the GP was looking for was that if you developed a method to turn lead into gold in orbit, you'd lose money on the deal - the per-kg cost to send things into orbit is almost exactly the same as the price of gold.

Of course it can. Lisp has a very vocal fanbase, but it's not actually any better than dozens of modern programming languages.

Yes, we should be grateful. It shows we have a language controlled by the people rather than the ruling classes.
Uh, what? What is this "cultural integrity" and how are we spending money on it?

Didn't the famously long-range RAF bombing make the Port Stanley runway unusable for high-performance fighters?

Given how many linux users (or people liking to pretend they're linux users) there are here, I'd say you're wrong.
New project in not yet being up to the standards of its mature competition shocker?

The binaries for slackware 3.0 were just one cd (yes it was released as two discs, but with slackware half the discs are always source).

I find it implausible that scientists would be working in Fahrenheit.
They also happen to be *extremely* left.
