I'm having trouble imagining how an extra cone in between red and green results rainbows and the like around the moon. I would expect the spectrum of light forward-scattered as moonlight propagates through the atmosphere to be constant over small angular shifts. I'd also expect the more interesting changes to be in the shorter-wavelength range, and the common tetrachromat theory (normal vision plus deuteranomaly) shouldn't have much effect at shorter wavelengths.

Anyone who likes calculating scattering coefficients or who has an appropriate spectrometer should be able to check this.
Just remember next time you talk about the 'War on the middle class' who's trying to give it ALL away in Paris this week.
There are still some old lowers kicking around in the military, but most aren't that old. When the Army buys M4s from manufacturers, they're getting complete new rifles, with new lowers. We need some actual military people to chime in here, but I believe that most rifles in current use don't have parts on them dating back anything close to the 60s, unlike B-52s, every single one of which has a majority of parts (including the entire airframe) dating back to the original manufacture date between 1952 and 1962.
Mathematics maybe.
Who is claiming she is insane? She has the gene for it, the question is is she actually seeing these colors.

Seems easy to test. You can test if I see reds, for example, even if you are color blind. Example: here's a rose petal that she says has many colors but we see one. Have her draw it and label it (not paint it, as not everyone can paint). Now give that same petal to another person that claims this power. Have them draw and label it. If their color maps agree, they are sensing something. If not, well, it requires more study. Seems pretty basic unless I am missing something.

You can add "which is" to turn it into a relative clause, but it functions just fine as an apposition.
The number I found was $60T, I used the money supply as I don't think that the rest of the wealth will actually be worth anything once all the cash is distributed.

You're right though, I missed a few zeros, my figure comes out to $8571.42. Either way, nobody's really better off. Sure, we'd all have enough to build a mud hut, but the damage done to the world order would far outweigh any improvements.
"They have a single IT person in the school who setup all the iPads"

This leads to an important side issue that people outside the .edu system don't understand, that you release a product for kids that is web based, my daughter's teacher can roll it out to the kids in about 10 minutes using a laser printer to make a QR code of the URL for the kids to scan and then do math drills or whatever, literally during a single recess period. In comparison, if you wrap the same exact content in an app, its going to take at least a year to get the app approved by the technology council and possibly installed, or possibly not if another teacher makes a stronger argument for using the limited storage space for video recording kid presentations of learning or their pet app or who knows, assuming you have the political clout, time, and motivation to ram the new app thru the system.

Educational apps are dead. Educational websites are where its at.
Networks in school are supposed to facilitate education. The standard approach of making everything impossible to use so that nobody can break anything may work in a corporation, but it does not work for education.
This seems intuitively obvious, but can you think of an example that wouldn't be answered with a competitive implementation using Cython or Numba?

I'd want to look at which states went shall issue during that period, or in which did the perception that people were legally carrying a lot changed. It would be past the first burst after Florida did it in 1986 and the "blood in the streets!" and "Dodge City!" predictions failed to come true.

You could argue the same about Windows / Office (required in a lot of schools), student discounts for software packages (notably Photoshop and other high-priced pieces of software), even Linux. There is IMO no such thing as a neutral choice of software, although free software doesn't have commercial goals so it gets more kudos from me. Still, you can't go "I only know vim" when your job is to work with Word / Excel (lots of jobs there).

It's not just France either. Authoritarianism is rife in much of the rest of Europe, and the rest of the world, for that matter.

France is a particularly interesting case, however. As on the one hand they're the land of Voltaire, of the French Revolution, of the ideals of "liberté, égalité, fraternité", and on the other of authoritarianism, colonialism, and xenophobia.

Well Banks is careful to point out that the Minds may, as far as we are concerned, be god-like but they can't predict everything (for various reasons, including moral qualms about too perfect simulations of individuals possibly having their own rights) and although they are perfectly capable of reading the state of meat based "minds" they don't do it as it's taboo (hence the "Grey Area").

> no book of religion pushes people to grab a knife or a gun to harm others

Yes they do. From the old testament (Deuteronomy 13, 6-13) http://biblehub.com/deuteronomy/13.htm

---

If your brother, the son of your mother, or your son or your daughter or the wife you embrace or your friend who is as your own soul entices you secretly, saying, ‘Let us go and serve other gods,’ which neither you nor your fathers have known,

some of the gods of the peoples who are around you, whether near you or far off from you, from the one end of the earth to the other,

you shall not yield to him or listen to him, nor shall your eye pity him, nor shall you spare him, nor shall you conceal him.

But you shall kill him. Your hand shall be first against him to put him to death, and afterward the hand of all the people.

Of course, no sane priest or rabbi would ever endorse such words today. Nevertheless, they are written there for all to see and misapply.

In the second segment they introduce a potential tetrachromat, Susan Hogan (not the same person as this article). I don't remember if her tetrachromacy was confirmed a real science experiment, I don't think it was.

But I'd still recommend the whole episode. All three segments were pretty interesting.

I don't think GDP is the right number to use here. If you redistribute wealth, then you're greatly affecting the ability of individuals and businesses to produce and sell more things, meaning you're destroying GDP by redistributing liquid capital. You can't redistribute non-liquid capital. What are you going to do, cut train cars into redistributable pieces?

Rich people owning the majority of the wealth is a tautology. If they didn't, then they wouldn't be rich.

That would make sense, except reality disagrees: long-term debt is salable. US 30 year debt used to be perfectly liquid, and even more extremely, perpetuities like the British consol have had no troubles being sold or traded. The US government did not switch to short-maturity debt after careful consideration and research proved longer maturities didn't work, it was much more accidental than that...
I could be wrong, as I only learned about the concept of a quine recently. But the way I understand it, it is good enough to simply output it. I suppose you could write to a file as well, but where would you write to? The wikipedia page for a quine has a lot of examples and all of them seem to simply output to stdout, just as I did. I don't think the challenge talks at any point about I/O, so I do think you can use it if you would want to.
Zeno's paradoxes are about convergence of infinite series, something quite puzzling back then. But the infinite regress problem here (or in related free will questions) is not about convergence.
I love org-mode, but I've just declared org-mode bankruptcy for my personal to-do lists and life projects. With my life being as busy as it is, I'm now rarely in front of a full computer with a keyboard when I'm at home, so keeping my home projects in emacs is not as appealing as it was 10 years ago.

I've tried running emacs on android -- too much friction for simple tasks that should be quick.

I've tried mobile-org; the workflow is painful.

I've tried orgzly. It's almost workable. Maybe when it gets folding, and I can simplify my syncing scenario.

For the time being, I've dumped stuff into Mirakel and ownCloud Notes...will see how it goes.
Yes, they used plain SMS, but that's irrelevant. What matters for the policy makers is the propaganda.

A Belgian minister saw a PS4 console in a terrorist's room and concluded that the bad guys used the encrypted PS4 messaging system to communicate. The newspapers ran with it and this is the official narrative even today.

Guess who gets more funding to intercept more encrypted communication? And not just in France. Italy is joining the fun too, with the postal police getting new "terror watch" units that snoop on even more stuff to keep us safe.
> There is not enough of what everyone wants.

Well, that's right...

> What if everyone wanted iPhones? There may be enough iPhones out there to give one to everyone in, say, New York City.

But that's not. Bad example. iPhone production can increase as much as demand asks for. If we let anybody build one, there'll easily be an iPhone for everybody that wants one.

Yet, there are few islands, beachfront properties, waterfalls... The things not available for everybody fall mainly on the non-renewable natural resources, with some slowly renewable ones at the borderline.

We can't make capitalism go away. At least not until humanity changes completely into something that craves what's available at space (mostly energy), instead of what's available at Earth.

So this is why you are a card-carrying member of a parapsychology association, right? Because many of the psi experiments, like Bem's recent ones, are better run than most psychology studies (sometimes much better run, as in, preregistered, highly powered, fully automated, and with adversarial collaborators running the study), and if you really believe that priors have no role in science, then you can't reject the psi studies without rejecting the rest as well.

I think you'd have to think about things differently. Imagine the people with only 2 cones... Now imagine if everyone only had two cones "I can't imagine how adding an extra cone would allow you to see these different colors in trees and the sky, cause there aren't any colors between blue and yellow". Color is a weird topic anyway because it is impossible to determine that everyone actually sees the same thing (which could explain why people have different color preferences).

There are wavelengths that each cone responds to. I'm not sure that there has been any research into the matter, but I imagine that this fourth cone adds a response to a wavelength either below or above normal visible range, or maybe more likely a person with 4 cones actually has less less frequency response by the other 3 cones, and the 4th cone fills in the gap, allowing for not really more frequency response, but rather just more specific.. And then with the magic of the brain, who knows how that enhanced response ends up being interpreted

And finally, when she paints to recreate what she sees, I imagine that paint is much more lively to her than what we are actually seeing.. which is a weird paradoxical thought experiment in itself

If you like the project, please star also on the github page.
Please feel free to comment, and maybe open issues on github.

I guess you could consider this a noob question. I'd like to get into this and more low level stuff in general.

Background:

I'm an applied math guy that works in cv, image processing, and anywhere that stats & optimization can be used. Work has recently led to learning more distributed stuff, albeit simply wiring up zeroMQ with c++ or python and getting the concurrent dances right.

Is it safe to say that Microcorruption is sort of a pre-req to this? Should I muck around in there first for a bit or sign right up for starfighter? Thanks.
I never said make everyone equal. I said redistribute obscene wealth. There is a whole greyscale between black and white.

I think there's a typo in HAKMEM: item 70 is a chess problem purportedly stolen from Lasker's Chess for Fun, Chess for Blood. As far as I can tell, it is problem 66 from Lasker's book, on page 145 [1]. However, there's a crucial mistake: the white bishop is supposed to be on QB8 (f8), not QB7 (f7). HAKMEM's version [3] is still a mate in 3 like advertised, but the original problem as Lasker has it [2] is much more interesting.

Where does that get us? Some small number of people get more wealth. Redistribution is not a solution for anything, all it does is destroy stuff.

I'm all for the expansion of classes that aren't ultra-rich and ultra-poor. But that process is already happening as fast as it really can happen, it's what globalization is if you can look at it with a rational eye. Through capitalism and markets. Big political solutions are sledgehammers that tend to only wreck things.
We have two problems, neither of which is a lack of water. We use water but we don't use it up. Our first problem is lack of cheap energy. Energy purifies water, moves it to where its needed. Our second is a lack of politicians with backbone, which is our own fault.

Where I live, my city pols subsidized water, people used more, said pols cried about water shortages and passed restrictions, while we are awash in fresh water. The city across the bay restricted waste early, implemented recycling, now has one of the biggest waste-water recycling systems in the USA, raised the price of city water while providing financial aid to the poor, and finally, showed ruthless backbone in locking in water rights elsewhere, including stealthy purchases using strawmen.

I didn't mean that you could output to a file -- I meant that, knowing the name of the file the program is saved to (which is possible using facilities available in many modern languages, not sure about Fortran), you can ingest that file and print out its contents (to STDOUT for example).

It feels like cheating, but it's also probably the easiest way to get a true quine which'll always work even if you modify parts of the code (while retaining the part of the program which ingests and prints out the file's contents).
