From the classical point of view, it is natural to assume that everything that happens in our world must have a reason. This reason may be hidden, unknown, but it must be; it is this consideration that underlies attempts to create a more detailed theory of the phenomena of the microcosm. But from the point of view of conventional, orthodox quantum mechanics, the theory of hidden parameters is impossible, if only because it does not have its own subject "behind the scenes" of quantum phenomena simply, according to quantum mechanics, there is nothing.
Is quantum indeterminism the absolute truth? I quote from Paul Dirac's book the Directions in Physics: "I do not rule out the possibility that Einstein's point of view may be correct in the end, because the current stage of development of quantum mechanics cannot be considered as final. There are many unsolved problems in this theory. Modern quantum mechanics is the greatest achievement, but it is unlikely to exist forever. It seems to me very likely that some day in the future there will be an improved quantum mechanics, which will contain a return to causality and which will justify the point of view of Einstein. But such a return to causality can only be possible at the cost of abandoning some other fundamental idea that we now accept unconditionally. If we are going to revive causality, we will have to pay for it, and now we can only guess what idea should be sacrificed."
Is this question open today in the scientific community, or does everyone believe that if Bell inequality has not been solved, then hidden parameters do not exist?

Viewing the universe as a cellular automaton seems pretty neat, and there appears to at least be some people [1] working on this approach, reconciling the results with the seeming implausibility of the conspiracy that initial conditions and determinism always conspire to result in violations of Bell's inequality.

I don't have the depth to go through that paper though so I'm not sure how valid it is.

I am looking to buy a "smartphone" (is this what they call them now?). I have no use for the actual phone itself, but I'd like it for other little things, like IRC and other crap like that.

So, where do I start?

Is there a reason why adblocker apps for android always seem to use vpn connections? Why is this necessary? Are there any out there that don't use one(rooted phone or otherwise)?
>> No. 2012 [Edit]
>>1502
Because you cannot set the hosts file on an unrooted phone, so the only way to do it at a global level is by tunneling all traffic through a local vpn which can then be locally filtered. If you just want adblock in a browser you can get that via firefox plus extensions or similar chromium variants that support adblock.

If you're rooted you can use adaway which uses the hosts file method (last I checked). There is also the option of using a custom dns pointed either at a local pi-hole server or a publicly hosted pi-hole. It seems the option to use a custom dns was only added in android 9, so for older versions you'll have to root it and modify one of the initrc files to override the dhcp-acquired value.

Greetings.

I recently noticed that one could express a polynomial in terms of combinatorials and so I am curious as to how far one could go with this.

My requests are:
1) An expression of n^4 purely in terms of combinatorials
2) A method for finding these combinatorial-expressions
3) Clarity regarding what the term is for this field of study my question would fit into (if there is one)

I notice Pascal's triangle appears consistently (albeit with the rightmost '1' cut off) so perhaps, keeping the positive-negative alteration in mind, the n^4 combinatorial-expression is actually quite predictable but I have yet to test this and to be honest, I'd rather find a method than apply what I predict could be the cheat-sheet.

>specific case of the Binomial theorem where y is 0.
I don't think you can apply this directly. Binomial theorem states that

(x+y)^n = Sum{nCk x^(n-k) y^k}. Substituting y=0 into this just collapses the sum to its first term, which is x^n. Additionally the expression OP has involves alternating sums of binomial coefficients.

I'm pretty sure the combinatorial proof posted is valid. I'm not sure if you can find a nice algebraic proof for it. I don't recall ever seeing an algebraic proof for binomial theorem (only the combinatorial one and induction. You could probably find some sort of inductive proof but I couldn't go anywhere with that.

>I mean, I don't get whether you are trying to understand it or to come up with a different proof or something.
I agree that there's not too much to generalize from this particular problem. However if OP is interested in this sort of stuff he should look up "combinatorial proofs." You'll find lots of delightful identities similar to the one he posted, which can be proved with very clever combinatorial arguments. Things such as sum{k=0..n, nCk)^2} = (2n)C(n).

One person said that this might just be the binomial theorem. I decided to explore this. From Wikipedia, one can see the formula for the binomial expansion when applied to (1+x)^n. I decided to apply this and substitute my result for n^a to see what emerges. This doesn't seem to resemble anything I've seen before. I must confess that I have seen "generating functions" on Wikipedia but even then, they're not similar to what I have here.
I hope the colour-coding makes my work easier to follow.
I think I'll return once more to post the equation for (m+n)^a at which point, the binomial theorem will be fully expressed as a linear combination of binomial coefficients. After that, there's nothing left but to derive a proof of the original rule I stumbled upon.

>>1983
The goal I intend to tackle at some point is to prove the formula I discovered i.e. that n^a can be expressed as a linear combination of binomial coefficients (or one could call it a a finite, alternating series of combinations, whichever one is most intuitive to you). As it stands, it seems to merely "work". That one side of the equation is the equivalent of the other remains unexplained.

>>1984
>I'm not sure if you can find a nice algebraic proof for it. I don't recall ever seeing an algebraic proof for binomial theorem
I don't know if there's a proof for the binomial theorem but nonetheless, I believe there might be an algebraic proof for this rule I've stumbled upon i.e. an algebraic proof that one is the equivalent of the other.

Since you're familiar with generating functions, here's a proof based on that. I think this is the cleanest algebra-only proof you'll be able to get for this, since usually proving combinatorial identities can get really tricky in general and there's no nice structure to this problem that you can induct over.

>What makes you so certain that I couldn't stretch this to complex numbers and have imaginary binomial coefficients?

You can have those of course; I think you'd have to use the generalized notion of a binomial where factorial is replaced by it's analytic continuation (gamma function). Once you go there I'm not sure if the proofs given (either combinatorial or via generating functions) still hold, since you've got issues of convergence to worry about.

I have a horrible coil whine problem.
My graphics card started making awful noises today, I can't figure out what the fuck.
Up until now it would often hiss or whistle on things like loading screens or intros like most cards do, but never made any sounds outside of that.
Today it started buzzing and whining like a dying lightbulb (but louder) almost constantly, even on idle in desktop. Sometimes it stops for a couple of seconds. The noise changes in pitch when doing things like scrolling and dragging windows. Stops when the monitor is disconnected. Stops when all windows and programs get closed but then starts again.
I didn't notice any problems other than the noise.
The noise is so fucked up I had to uninstall the thing. Please help.

Not OP but coil whine is a pretty-well known quirk of electronics. I think it's the inductor that's actually responsible. I have this on my laptop on any gpu intensive workload.

I think besides mitigations like double-checking inductors are secured to the board and getting a soundproof case, there's not much that can be done.

This thread is computer/technology related, so /mt/ is probably the best place to post it.

Anyway, to the point. I've been hearing many rumours that the soon to come Windows 8 will have forced "Live integration", which means (you guessed it), forcing you to register on Live before being able to use the OS. From that moment on, I realized that Microsoft will either fail completely as a Software manufacturer or the oblivious masses will bend over. To my (almost expected) disappointment, it is the latter. The masses will accept this as they have done so far. I'm talking about the social networking shoved in people's faces everywhere. You can't go to a large website without seeing facebook and twitter links everywhere. Hell, even online gaming has turned into one big social network (see Steam, Xbox Live, etc.)

The question I pose is, what's next? Requirement to have your real name visible everywhere you post? Or maybe forced cloud computing? Web 2.0? Seems likely.

They're already putting tracking devices in smart phones:

As >>1828 mentioned, the big companies are going to be pretty unaffected. They can afford to (and already have) developed ML based content ID systems to automatically take down content. Google, Facebook, and co. will probably set it to be even stricter in the EU and call it a day.

Meanwhile the law will only hurt small startups and indie businesses because they can't afford to/don't have the manpower to do the above. And it'll also hurt end-consumers as an end result in two ways: 1) there'll be less competition from these small businesses and eventually people won't bother trying to create services catering to EU citizens so they'll be stuck with big goliaths that will only become entrenched and incumbent. 2) Smaller niche content/sites may also become unavailable to EU citizens, as even those possibly under the exception clause mentioned may not want to risk violations or bother so they'll just block EU IPs.

Nanotechnology! It's the future of everything. Every machine can either be replaced or greatly improved upon by nanotechnology, including the human body. From medical delivery to computing. Nanotechnology also has a lot of applicability in weapons. The hypothetical "pure fusion" bomb doesn't require fissile material, which is a major barrier for making nuclear weapons now, but creating it requires pressure and heat that's not practical with current technology. Nanotechnology however could create the necessary conditions and massively reduce the weight of the bomb. Then there's the grey goo scenario where in one day self-replicating nanobots designed to "take things apart" dismantle the entire planet. Are you terrified or excited?

Have any of you guys heard of the SAFE network project? The basic idea is that the network will be fully automated and use spare resources from users' computers to store all data in exchange for some cryptocurrency(I don't like this part so much). Data is both enycrypted and distrubted in such a way that makes its source and destination impossible to determine rather than just masking activity. The system automatically splits data up and makes multiple copies of the parts. As a consequence, it will be impossible to delete information once uploaded. I don't have the technical know-how to say how legitimate it is.

The mention of cryptocurrency tends to lead me to dismiss projects on sight.

I don't think you understand the scope. The goal of safenet is not to just to send and store files. It's meant as an entire replacmenet for the http protocol. Websites, applications, everything that currently exists on this "internet". The idea is a complete replacement with zero oversight on the overall network. Torrents rely on seeders and the information can't be accessed in real time. People who store data for safenet wont even know what they're helping to store. Nobody will.

The end point of technology will be our destruction. Man is a cosmic accident, there is no point to us, but we still can function because our environment is still reasonably close to the original. Our biological programing still good enough for our situation. Yet more and more technology changes the game faster than nature can alter her program. Take obesity as an example, for nearly all of human history there was no such thing as a problem of constantly having too much food. In the last hundred years technology has made food abundant, making our own biological drives so suited to millions of years of hominid life moot. How will man's programed urges react to the new weights on the scales? What will happen when chance no longer is a major factor on human lives? What happens when most people become useless, when the systems we make outstrip their creators? What happens when we can alter genes freely. Or when we can alter people's moods, their minds, their capabilities? What happens when one can retreat into a virtual world to reign as God?

We will break ourselves. We will see what we really are. Living automata, a biological paradox, an abomination, an absurdity, an exaggeration of disastrous nature. Nature will no longer be able to correct her mistakes, we will be a species made almighty without, but equally a menace to its own well-being.

The results will be disastrous. Technology will peak when we can freely change one of two things, ourselves or the environment. In time those who change themselves will become infinitely malleable nothings, true Sartreans who's existence may blink out in an instant, both more and less than human. Those that seek not to change themselves but that which is external to them will retreat into virtual worlds, induced feelings, human similcra, a solipsistic suicide. In any case it will be nothing short of collective death. So long as technology advances faster than nature can create counter-measures, we will overshoot her target, blowing us apart in the process.

In genesis man's original sin was to eat from the tree of knowledge. Technology, fruit of knowledge, will perfect our fall. It will be a final complete fall where we shall lose even the memory of paradise. We will finally know ourselves for what we are, stand apart from ourselves look upon our species and find

Reading over his essay again, he was pretty prescient about political issues brewing today and his argument that technology takes away individual freedom and leaves purposeless "surrogate" activities in its vacuum certainly seems compelling. The issue is that it's really hard to make a definitive comparison since we have no frame of reference for the alternative Kaczynski seems to propose: reverting back to a hunter-gatherer style society. Sure we might have a greater sense of purpose in our lives, but that might only be because we're busy fending off tigers and too preoccupied food and survival to worry about anything else.
