Somehow, even though Collapse is insane if you think about it hard enough, and even though Pilot-waves are semi-classical and seem to be adding an additional complication that may not be necessary, both of these seem to be more popular among physicists than Many-Worlds. Somehow, even though superposition is observed and observable, even though the scale on which we can observe it is climbing steadily larger, people keep assuming that it either dissipates sometime before our scale, or that it's an illusion produced by some sort of semi-classical, overcomplicated reinterpretation.

The original idea—that the wave function is the whole deal—works just fine if you accept that we can be in superposition too. If you simply accept that the entire classical concept might be an illusion, and work up from the wave function, there's no reason to shoehorn in an idea like Collapse or Pilot-Wave.

Yes, Copenhagen is wrong. Yes, Collapse is patently absurd. Yes, assuming that there is exactly one, stochastic, probabilistic reality makes no sense. But that doesn't mean we need to add something complicated like an underlying superfluid that supports all of spacetime. This smells like Aether.

Why does no one talk about Many-Worlds?

Show HN: Elliptic Keyboard – made for my personal needs, now is for everyone
Good evening HN!
I've made a keyboard for LARGE iPhones, so you can use it one-handed without risk of dropping it.

Here is the link: http://appstore.com/elliptickeyboard

It's now in the AppStore with version I should have called 1.0 :) Contains few languages and usually expected features. Left-handed layout will be added in next minor release, along with swipe gestures for space and delete.

I'm looking for suggestions from experienced developers, about UI, functionality or just everything. Currently I'm trying to add OpenAdapTxt as suggestion engine, compiled universal library, but having problems to make it work. If you ever had experience with it - please, help me :) Or may be using Hunspell is better way.

Sincerely, young developer
On one hand, no, of course not. It's a voluntary transaction between adults. There's no taking advantage of someone who comes willingly. I used to think this.

But on the other hand, if some people are getting really really rich off the labor of some really poor people than it's gotta make you wonder a bit. And the risk distribution has really got to make you wonder.

Uber, being big and diversified could easily take on that risk and insure against it (or really just self insure with their scale). A single driver on the other hand could be completely wiped out by bad luck. Uber isn't doing this though. Why is that?

It's certainly worth thinking about more deeply than simply shrugging and saying that you can't take advantage of someone in a voluntary transaction.
You beat me to it! Now you get all the sweet, delicious karma.

Author here (as some of you know already). I'd love to answer any questions you have!

the surface is a PC like any other. wacom even works out of the box. you just have some trouble with pressure settings. Touch screen is also a done deal on almost all windows laptops. never saw one not working in recent times. the wifi and audio are the usual suspects of linux hell. and in this case it was true, as it always is. but both could be worked around with know-to-work USB devices. though wifi seems to have been solved.

anyway, the link has a video.

For perspective, the S&P 500 was at 68.56 in 1975 and began 2014 at 1848.36, a 27 fold gain. You also wouldn't be paying ongoing real estate taxes, etc. So the house bought in the 70's wasn't that great of an investment, long term.

If this leads to an experimentally verifiable prediction different from the current view of quantum mechanics, it's a very big deal. Otherwise, it's not.
It's not illegal to export the system, you just have to get BIS/NSA permission to do that.

I see a few possible explanations on why they allowed it - 1) NSA was satisfied with their intercept capability (likely around key generation / exchange being based on cellular network/SMS) 2) they decided that the technology was a commodity and it's best to have Apple dominate it (where they can still attack the data center or use legal means) rather than cede it to a foreign power.

I'm just guessing though.

There's an issue here: For the air compressor,
how does that work?

There is the roots idea
of two lobes, maybe a foot long each, interlocked like two gears, inside of a housing that is so tight against the
lobes that there are no air leaks. So, talking a lot
of friction. Then, roughly double the RPM of the
compressor and double the amount of air moved.

Corvette and Dodge are using roots.

Then there is a centrifugal compressor: It's simpler
with less friction, but double the RPM and roughly
square the amount of air moved. So, at low RPM,
move too little air and at high RPM, move too much.

So, centrifugal air compressors, for supercharging,
driven by a belt off the front of the engine, had
the compressor RPM directly proportional to the
engine RPM with too little boost at low RPM
and too much boost, and too much power to drive
the compressor, at high RPM.

The beauty of the usual exhaust driven turbo
charger is that the exhaust side took the
square root of the exhaust flow and the
cold side squared it again and, thus,
moved air volume directly proportional to
engine RPM -- great.

But with an electric motor, could have a
centrifugal compressor, the simpler mechanical
option, always with the right RPM, not directly
proportional to engine RPM.

Of course, could also have a turbine, that is,
with little blades like in a turbojet engine --
these tend to be expensive.

The things that are wrong with K-9's interface are similar to the things wrong with Calibre's interface: they're powerful and capable, but completely defy convention, host an enormous amount of complexity, and can't be fixed piecemeal.

Things I dislike:

- The empty K9mail-errors virtual folder that I can't hide.

- The completely nonsensical sorting of folders (alphabetical by Folder Display Class, but there's no visual distinction between display classes, just an arbitrary point where your folder alphabetization resets).

- The quadrumvirate of Folder Display Class, Folder Sync Class, Folder Push Class, and Folder Notification Class are completely inscrutable.

- Even if you understand the class system, setting them requires one long press and 9 clicks per folder.

- I have to reach all the way to the top left of my phone to go from my inbox back to the list of folders, instead of following the common UI pattern of allowing me to pull in the folder list with an edge swipe. Tapping the top left is becoming more difficult with each increase in display size.

- I can't reliably refresh the folder list from my server, especially when it comes to special folder labels (Sent / Drafts / Spam / Trash / Archive)

So, it's mostly that the UI is pretty bad. Not unusably so, mind you, but neither is Emacs. The catch is, I just don't understand what benefit I'm getting from struggling with that interface.

And the issues are pretty endemic to the data model that K9 is built upon. To fix this, you'd need to completely re-think the interface and throw out the entire class system, which would raise another round of questions regarding how to handle selective mailbox synchronization, etc.

That downside is not a downside for Intel. Having employer lock-in keeps costs down and turnover low.
There seems to be another point in the
article but not emphasized:
The potential role of direct fuel injection.

So, go ahead and let the compression ratio
go up through the roof, from the piston in the
cylinder and/or the supercharger. And, don't
bother working hard to cool the compressed
air before letting it past the cylinder
intake valve.

Why cool in the past? Because otherwise the
heat of compression would cause pre-ignition.

What's different with direct fuel injection?
The fuel is not in the hot air in time for
pre-ignition. So, basically have a Diesel
situation and, indeed, might not need a
spark plug! I'm not sure people are taking
advantage of this possibility now, but
have to suspect that there is an opportunity
here.
Because it's an oxymoron?
If the "worlds" interact, then it's actually one world. If they don't interact, then it doesn't matter.

> ...pilot wave theory--which is taught in every introductory QM course and covered in every introductory QM text...

Having assisted in teaching intro QM courses, I can say this is very incorrect -- unless you replace "every" with "many" and "taught/covered" with "mentioned off hand".

I just pulled the very popular "introduction to quantum mechanics" by Griffiths off my shelf. It contains nothing about pilot waves except for a single footnote in an appendix used as an example of "a number of hidden variable theories [proposed over the years]".
These are all components, not systems. A system would be something akin to a full-bank installation with all the computers, cabling, routers, crypto protocols, key generation/escrow/rotation/destruction, fall-back procedures, firewalls, hotglued USB ports, etc.

You can use those components to build a system like this, but you have to be an expert in it. This is why component export is restricted - all they want is to look into your design to see if you are an expert capable enough to design and implement a secure system. What happens if they pick interest in you is beyond my experience. I know, it speaks poorly of my crypto skills, huh?.. :) I imagine they would start looking into identity of the client(s), and see if they are connected to embargoed entities. Or something...
The reason is aesthetics. No buttons makes it look sleek, which is all the OEMs are going for. Same reason has driven the other changes in recent ThinkPads. It's purely about looks, with making it functional coming far behind. (One example of many: New ThinkPads have no way to determine if they are charging/plugged in, except by carefully looking for a few seconds after a state transition. If the plug is loose or another problem happens while you think it's charging, they give you no notification. This is purely a twisted sense of aesthetics, trying to make it feel less IBM. And on more than one occasion, this has caused me serious issues as I discovered too late that my system was out of power.)

> It appears that the current quantum mechanical view of the world is simply an acknowledgement of this complexity and the associated unknowns. While it presents a statistical "model" that works for our purposes, it must be acknowledged as a model and not confused with reality. The push for figuring out what drives the statistics needs to continue beyond the building of a model.

This is not a accurate representation of quantum mechanics.

If you were to write down a classical description of the state of all the particles in a piece of paper and the state of all the particles that they might interact with over the course of a few seconds, and you solved the equations for what happens, you would get an exact description of the result. This description would be wrong if you look closely enough because classical mechanism doesn't correctly describe the universe we live in.

If you did the same thing with a quantum description of the initial state of the paper, you would also get an exact description of the result. That description would be very strange -- if try to deduce what you would see if you looked at the piece of paper (remember, you're just a bunch more particles interacting with that paper), you learn the bizarre answer that you would seem to have some chance of seeing the paper in one configuration and some chance of seeing the paper in a different configuration.

But there's no respect in which quantum mechanics is an acknowledgement of some kind of complexity that is beyond our computational ability to describe exactly. To the contrary, quantum mechanics is our attempt to describe things exactly, and it works amazingly well.

It's certainly true that a full quantum description of all but the smallest systems is far beyond our ability to compute directly. That's when we switch to statistical mechanics or similar techniques to try to deal with the complexity in a manageable way.

To the pedants: if you're trying to model a piece of paper with quantum mechanics, then you'll have to approximate the very small-scale high-energy bits, because we don't know the laws of physics at those scales. But there is so far no compelling reason to believe that those laws will not fit perfectly in the framework of quantum mechanics once we figure them out.
How I made the print and eBook versions of my web book
As a woman in IT, if your pay is less than your male counterparts, it may not be that you are less competent, and it may not even be that your employer is biased. It may be that your employer is simply paying you a market wage, which is lower for you than for your male counterparts because there are other employers who are biased against you, therefore the demand for you is less. Its about supply and demand, not necessarily bias from your specific employer. Its bias from the market as a whole.
However, there is cold comfort in knowing that you are competent and more valuable than others paid the same as you.
No. Quantum mechanics is fundamentally different than all those examples you gave, because they all admit reasonable hidden variable models (i.e. unknown or intractable degrees of freedom which we can nevertheless assume to exist and explain our ignorance). Bell's theorem shows that this is impossible in QM.
Only "faster" because you precompute digits of the golden ratio, and will quickly become inaccurate unless you compute more of them

Sure, O(2^n) is an upper bound here. O(phi^n) is a tighter bound.
You're right, although the "<" symbol isn't technically correct notation. I think O(phi^n) ⊂ O(2^n) or O(phi^n) ⊊ O(2^n) would be more correct to indicate that the left is a proper subset of the right, given that big O notation refers to sets of functions.
Great guide - the only material I've ever read on the subject, that hasn't completely made my head hurt and my brain not grok. I'm not a maths or ML guy, just a regular programmer. I've dabbled in NN before, but only to the extent of using some libraries as a "black box" to pass parameters / training data to. No doubt there are many more people like me (too many!).

My understanding after reading this guide, is that a neural network is essentially just a formula for guessing the ideal parameter(s) of another formula, and for successively refining those parameters as more training data is passed in. I already knew this "in theory" before, but now I think most of the magic and mystery has been brushed off. Thanks karpathy!
Inbox is for people who don't have a workflow / need help organizing their workflow. The app looks neat, but I already have my own workflow and it doesn't fit in it so that app is not for me.
Well actually it does. Every time you do an someArray.push(val), that's "object oriented as a style of writing code".

If you're referring to the style in the article (ie the Java code), well that's classical object oriented.
It strikes me, as do a few other posts and comments from YC that this is an incredibly American centric view of the world. I've heard PG say "just consider moving here" but without a visa as a startup that's very difficult.
There is no need for "belief". There is only support by predictions validated, or skepticism borne of predictions disproved. The important work should discover predictions which distinguish these two models of the interactions of the very small and then put them to the test. Anyone who remains satisfied with self consistent mathematics alone is, as you say, approaching "religion", (unless it's a thesis in pure mathematics [smile]).
I think that these oil droplet experiments are incredibly neat, but I'm surprised by the conclusions about the universe that people try to draw from them.

There are fascinating lab experiments related to black holes [1]. Researchers have figured out how to build things in the lab that obey some laws that are mathematically very similar to those that we think that black holes obey. These black hole analogues end up doing similar things to what we expect real black holes to do.

Nonetheless, no one seems to see those experiments and conclude that "Wow! Our universe must contain black holes that emit Hawking radiation!".

These oil droplet experiments do something quite similar. They create an environment that is reasonably well described by the same equations as pilot waves, and, since those equations are known to make the same predictions as quantum mechanics, the oil droplets do the things that we would imagine quantum particles to do.

This may be beautiful, but just as the existence of black hole analogues in the laboratory does not imply that black holes are real, the existence of pilot-wave-following oil droplets does not imply that pilot waves are better than quantum mechanics.

Turbo/Super chargers do not improve engine efficiency (more power with the same amount of fuel). They improve VOLUMETRIC efficiency. To put it plainly, they allow you to shove more fuel into the same size engine. To burn more fuel you need a lot more air, hence the compressor. The same engine produces more power by burning more fuel per unit time.

As far as the 10% fuel economy improvement (i.e: 20 to 22 mpg) by combining cylinder shutdown with electric turbo is concerned, well, I'll give them the benefit of the doubt and remain very skeptical.

Do any of the claims account for non-trivial compressor motor power?

If we dig deep enough are we going to learn that this company got a huge grant from the EPA? It feels like the whole business of solar bike paths in Holland.

It's been a long time since I studied Thermodynamics. From what I recall engines are cycle limited and modern designs are optimized as far as you can go without resorting to esoteric optimizations. In other words, as long as you have an Otto cycle engine that's your limit. I seem to remember 18% max thermodynamic efficiency for Otto cycle under ideal conditions. Stirling cycle can do 90% efficiency, again, from memory.
