This would be true if they used a head simulator for recording. Since they don't, you will get the wrong projection. All headphones sound more like "the concert is happening between my ears" than "the concert is happening on a stage in front of me".
You're going to have to point out the contract with my signature on it where I agreed to that. My attorney is gonna hear about it...
But when you "collapse the wavefunction" and "create" the internal state of the particle, do you also create the internal state of the other one that is entangled to it? Do you create it instantaneously?

You see, the problem is not whether you can transfer information in human readable form (though if you could that would certainly be a huge problem with relativity!), but whether any effect that propagates faster than the speed of light exists.

You'll have a hard time explaining that in the frame of wavefunction collapse, I think.
Would you mind sharing a bit about the architecture of this project? What tools and technologies & language (beside lua) did you use? I'm guessing you just need custom routes (all the URLS are on your domain?) rather than custom DNS. How are you handling sending emails, for instance? (did you plug into an email as a service provider?)
haha touche. Granted... Mutt was terminal based....
We are really proud & excited for this one!
> both particles have a superposition of k and ~k (to use your terminology). ... This "internal state" simply does not exist until the wavefunction collapse has occurred.

What would the implications be if particles did have an internal state?
Introducing the HelloSign API: Hassle-free eSignatures (YC W11)
Nice, It would be awesome if one could get full capability of a programming language. I have been planning to build something like this but was stuck because of the sandboxing issue.
This article completely ignored the Many Worlds Interpretation, which preserves all of realism, locality, and Relativity.
How are they inefficient? I'm designing an app right now and am looking at different frameworks to use. Any recommendations?
Nope. Pushing on the end of the beam sends a pressure wave through the beam. The button gets pushed when the wave reaches the other end. Wave travels significantly slower than light.
Okay, now I get it: You're trolling HN. Good for you. You got me.
Thanks for running pressureNET! Whenever we show some data analysis, you can bet it will be on our blog at http://cumulonimbus.ca. However, you'll note that there's not much there so far. For the majority of the life of the project, we haven't had enough data to do anything interesting with it. Now, however, especially with Sandy (we gained 1,400 users yesterday alone), our data will be of immense value. We're working with a couple of researchers at universities (U Washington, and McGill) to best use and analyze the data. The answer to your question, though, is:

You can see our data by purchasing our weather prediction app that we'll build at YC this Winter. ;)

[Side note: we also plan on building a web version with a nice HTTPS API so that you can access the backend yourself. However, there are severe privacy issues to solve first and we're still working on that. Sorry about the delay, but until we find funding, pressureNET is a free-time-only project that moves a bit slowly]

[Edit: For pressureNET contributors like yourself, by the way, I plan on giving the predictions away for free. Anyone who does not/cannot contribute would have to buy the app. Or something like that]
When to compete on an idea
Microsoft sold 4 million Windows 8 upgrades in three days
This looks like a really, really fun project. Great idea.
It is actually not about serving content. Custom domain makes the fail over much easier. For example, someone uses webscript.io as his app backend. If webscript.io goes down for whatever reason, he can simply point the URI to a backup server(provide he has one) if he uses a custom domain. Without custom domain all he can do is wait.
Relativity says that you can't construct a rigid beam 25 million miles long.

Clever ideas, on both counts (webscript and site44). I wish you and Todd success.
Here's the blog post announcement: http://blog.hellosign.com/?p=65
BTW you can fix both of these issues by disabling Javascript for http?://www.google.com/search/* (I use the "site preferences" in Opera for this, but I assume other browsers have similar built-in features). What you get back is something very much like the old vanilla Google web search.

I used to have it for quite some time, new laptop set it back to normal, and for now it hasn't quite annoyed me enough yet to set it again (also because I'm using DuckDuckGo much more these days, for similar reasons), but it was good when I had it.

I really wish Google had some setting to turn off this "instant search update" thing, as well as how the input box continuously steals the focus (this breaks many keyboard shortcuts in Opera), because the other interactive/dynamic features they do with JS on the web search page are quite useful.
Under "Voice Search" in settings try changing the default language to US English.
By the time most people could afford any of this equipment their hearing has probably degraded to such a point that they can only hear 12kHz to 14kHz anyway.

Although unscientific, I played some tones on youtube in the office and the twenty somethings could hear almost 20kHz and the forty somethings couldn't hear anything by the time the frequency sweep was just below 15kHz.
Very high quality audio reproduction can be hacked too, and audio enthusiasts like myself know how to find deals and hacks to get superior performance with much less money. For example, I have a circle of friends who upgrade the OPAMP chips on their sound cards ($10) or use Sonic T-Amp ($30 triclass T-Class digital amp rivaling hifi tube amplifiers) paired with passive studio monitors from Wharfedale, Celestion, or Tannoy (around $200 on ebay when recording studios upgrade to powered monitors).

I originally thought you actually needed to be situated in the Indian Ocean in order to get a .io domain. It might lead to some confusion (although I assume the tech savvy generally look at the TLD).
> Google needs to be usable by everyone.

Why does Google need to work the same way for everyone?
I built my system in a similar way (e.g. a great Threshold S200 amplifier from the 80's cost me $700).
One frustration I had was never being sure what is a good price. In part to scratch that itch (as well as the "learn Haskell" itch), I've built http://kruipen.com to track used audio equipment prices.
You seem to be forgetting about the billion or so human-made combustion engines, that are easily capable of altering the global climate in a few years.

Or about the tens of thousands of nukes, that can strip the poles of ice caps if properly deployed and again completely change the climate.

Or the probably achievable proposed projects of building solar mirrors or seeding the south oceans with iron.

One can look at the amount of energy humankind was commanding 300 years ago and now, and than extrapolate that to the next 300 years. That power would be enough to move stars around, not talking about a single planet surface fluctuations in gas pressure.
Yeah. It shouldn't be that surprising that when you arbitrarily assume that part of the wavefunction magically disappears sometimes, you get weird results like non-locality.
This is because we have to poll each services API. Anymore and we'll reach API limits. The goal is to move towards more webhooks and push notifications so that real time becomes a real possibility.

The video is a funny scene from a classic movie about a fringe culture. Arnold is playing with Lou Ferrigno's confidence.

Arnold says that they should have extended the Mr. Olympia contest (the deadline) because Lou (the competing startup) still needs to get in shape. Arnold then pours more salt on the wound by saying that on second thought Lou would still lose because Arnold (the venture-backed, TC-covered startup) would also have that extra time (extended deadline).

Arnold was actually a funny guy way back before he thought teachers/cops/fire/ems should get less benefits and Hitler was "admirable".

Btw I do think the extending the deadline is a great thing but didn't vote for/against it because it helps me, and I passionately believe in not voting about things that are in my personal interests.
Maybe this isn't the sort of thing that should be posted here, but so many of us here have money to spare, and so many people are facing such hardship. Please consider donating or giving blood.
I didn't know either, I don't mind comments like this if they are actually relevant.
The whole thing is a Python app, written with Flask. As you said, we do custom routing to map URLs to scripts, which we then load up in a Lua VM and execute with conventions for how we pass in the request and interpret the return value.

For email, we just support SMTP. You have to bring your own server and credentials. Our examples are using Amazon SES, but anything would work (e.g. SendGrid or even GMail).
We're not currently planning to change that, no.
I followed the links and .NET applications are also compiled AOT before being made available for download.

Agreed; that's what I was trying to say. Perhaps it's disingenuous to frame the problem in this way (that is, talking about rule books and the like), but I was just trying to make it more relatable to normal human experience.
Ah, good point; thank you. We'll give this some more thought.
New 2012 Giants World Series Quiz
I agree with you. And further more, wouldn't entanglement itself be some sort of evidence that the particle does have an internal state even before being observed?

For instance, I could phrase things like this:

- Let particles A and B get into an entangled state

- Measure the state of particle A, see that it has property k.

- Predict that B has property ~k even though it's not being measured yet.

- Measure B. If B has property ~k, then we've proven that B had an internal state before we performed the measurement.

From all the "popular" description of "quantum entanglement", I don't see anything in it that's significantly different from things like, say, the preservation of momentum in Newtonian physics.

Of course, I must be missing something, but I don't know what is that thing yet.
Application for what?
I think that's going a little too far. If you can construct a "rigid beam" five feet long, I see no way that relativity countermands a "rigid beam" 25 million miles long. It's just that "rigid" doesn't mean what grandparent thinks it means -- info still travels through the beam via pressure waves.
"Hummed my application to YC through a harmonica, Trimline phone, and an AOL Dialup account - during a hurricane!" ;)

Though in all seriousness, I think this is a nice touch PG. In the poll thread people seemed to have jumped into the shark take a little too quickly. Compassion is an important virtue and its nice to let people deal with their current crisis without worrying about getting their application in.
It would be a violation of Bell's theorem as we currently understand it. In other words, it can't happen, unless our understanding is wrong. (For more info, the wiki on Bell's theorem has been linked to elsewhere in this thread.)
The thing is that "slow" is naturally relative. I hate it when people claim that a tool is slow. By far the most important factor in getting programs that work isn't the technology but the mind behind the code. This is true for any programming language.

I guess the succinct answer is: No, Erlang isn't slow if you know what you are doing, barring the Caveat about CPU-bound problems. The message I am trying to convey is that there is more to fast programs than the execution speed of the technology at hand. It is a factor, admittedly, but it is not the sole factor.
It is impossible to construct a perfectly rigid beam, in the sense that you are thinking of. A "rigid beam" would be made up of matter and, as you push on one end, you would trigger a wave that would propagate from neighbour to neighbour until it reaches the other end.
I tended not to use the more ugly timers... and yes, I truly did burn my pizzas.
awesome! this makes up quite a bit of the love they lost with their abyssmal redesign earlier this year!
Agree with everyone else, on LTE this is blindingly fast. I also played with the goggles feature which read text on a watch face, identified the building I work in and seemingly instantaneously ocr'd text on a postcard!

This is what I like about Hacker News; when I ask a deeply technical question in a field removed from my own, there are plenty of people who can point me in an interesting direction.

Bell's Theorem was the aspect of observational measurement that I was missing, and it's absolutely fascinating. Even moreso in that it was envisioned mathematically before we had the technology to prod at its claims. Thank you everyone for showing it to me.

This may be a stupid question, but is there an equivalent Android app?
Intel recently released its "Medfield" SoC. It beats ARM cores at similar power envelopes, and is currently available in a few phones.

Of course, it's a single-core processor as opposed to the double or quad core ARM processors that it's up against, but the point is that they're getting quite close.
I second the Android Police suggestion. They really do a great job highlighting good android apps.

For anyone curious, here is a recent app roundup they did.

Speaking on a tangent. Has anybody not found it annoying that you can't auto-BCC yourself in Gmail? Only if you do so does it pull up the message thread to the top which I prefer to keep track of timelines. I would be fine without the BCC as long as the thread reflects my response time. Either way, room for improvement.
Yeah, what I meant by "amp" was integrated USB DAC + amp. I use a Headroom Total Bithead, which isn't the best, but isn't the worst. I am not really sure what the best in various price ranges would be.

There's huge variation in quality of headphone-out on computers. I'm sure some are good, and most Apple products are at least ok, but I've usually found even the lowest end (CMOY, Filo, etc.) is a big improvement.

(plus, the amp is really helpful for high-impedance headphones. Mine range from ~30 to ~600 Ohm.)
It's so, so fast, but seems to have trouble with accuracy, at least when I've tried speaking to it. It almost seems to decide on what I've said earlier in my sentence before I finish my sentence, which I'm guessing is lower accuracy compared to waiting for me to finish talking before analyzing.
I'm not sure why you keep saying 'looks like Twitter'. Bootstrap was originally created by Twitter, it wasn't created to make every site look like Twitter - nor does it do that.

As for your other comments, you seem to have a far greater knowledge and skill level dealing with CSS than you let on. That's great for you, it must make doing frontend work a breeze - and maybe you don't need Bootstrap. Not everybody is so experienced though - and for them, Bootstrap can make life much simpler.

Um... You COULD spend a lot of money, or you could learn some basic electronic and woodworking skills. I built a set of ZDT3.5's (Google it) for $250. I built (from various kit pieces) my own T-amp for $75 to power them. Your Mac already has a great sound card capable of extreme sample playback rates. A couple of FLAC recordings later, you're in business.

I hate this article, because locality is an important property that we think reality does have.

Wow, imagine if Apple actually exposed APIs that allow Siri to do what it does? This app would destroy Siri.

Edit: I'd go so far to say this is eerily similar to the issues levied during Microsoft's anti-trust case. Google clearly is unable to compete here for no other reason than artificial walls put up by Apple on their devices in software. This is mobile's IE vs Netscape.
Likely. The other way to look at it is that many of the apps that are present in Windows phone app catalog are the ones where Microsoft convinced the app developer to write for the platform specifically. Now if that strategy is used then its obvious that Microsoft would have courted the top quality apps rather than going after poor quality ones.
If you push on the beam and the other end does not move right away doesn't that imply that the beam has compressed and is not rigid?
"If B has property ~k, then we've proven that B had an internal state before we performed the measurement."

This part is the flaw in the logic. That doesn't prove that B has an internal state. All it proves is that, in some sense, B's state is related to A (assuming you repeat the experiment until you reach statistical significance).

Entanglement is nothing more than saying one particle is connected, in some sense, to another. Like a see-saw: if one side goes up, the other must go down. It's only "confusing" in the sense that the particles are physically separated, and the link between them is not mediated by a force as we understand it. Instead, they're linked by their very nature. It's almost as if you have just one particle, that's somehow been split into two and spatially separated. That's the conceptually difficult part.
I like it, great idea! I was really surprised about Lua's choice rather than Javascript since it's all web-based. I'll definitely give it a try.
This article[1] by David Mermin does a good job explaining why the second particle couldn't have always been a ~k particle.

"Looks like twitter" is just shorter than "looks like every bootstrap website on the internet". My CSS knowledge and skill is very low, I'd rate myself a 2 or a 3 out of 10. I tend to leave the design work to the designers whenever I can. I certainly agree that a default stylesheet is quick and easy, I just didn't realize that's all boostrap is. Now I know the answer to the question everyone keeps asking me ("why aren't you using bootstrap") is "because I already have a default stylesheet". Previously my answer was "I don't know what I am supposed to do with it or why".
I didn't realize that Ursula Le Guin coined that term. My first recollection of it was from Orson Scott Card and later, Dan Simmons. In any event, entanglement certainly doesn't look like it will lead to an ansible yet.

I would imagine that Lua was much, much simpler to pick apart and integrate into a system like this (from my experience using Lua) than trying to use a full JavaScript engine.

What you're proposing is an effect mediated by physical forces. Specifically, on a fundamental, atomic level your beam is made up of atoms. And when you push it, you're bringing atoms closer together, that feel an electrostatic repulsion. And the beam moves.

So, in the best case, this method of communication is equivalent to communicating with electromagnetic waves. And they have a speed limit: the speed of light :)

So this wouldn't be faster than light communication.
"Nobody who feels that a $4,000 power cable is important has any semblance of sanity remaining."

This line of argument is one of the most common attacks against the 'irrational snake-oil' that audiophiles purchase. Yet, I have to disagree. Its not that I believe that a $4k power cord has any/significant technical advantage over a $4 power cord. You used the words 'feels' and 'important'. The feeling of listening to a $4k power cord is clearly internal and subjective as is the determination of its importance. If the listener 'feels' that the $4k cord makes a difference, makes the experience better, then it has value to them and I think that they certainly have the freedom to assign how much importance it has. If audio is your passion, then perhaps there is real value, if perhaps only symbolically, to devoting large sums of cash to it in tribute. In my experience, audiophiles aren't simply gullible rich guys mindlessly blowing money on $4k power cords. Many have very deep relationships with music and with their stereo equipment. This relationship is often complex and rich enough that spending large amounts of money on a new 'X' would almost be like purchasing your wife a gold bracelet. Almost.
