I think that the dynamic vs static debate also depends a lot on how you program. For example, there are people who like to write a few lines, then test, write a few more lines, test again, and so on. For them dynamic languages are prefect.

On the other hand, I am the complete opposite. I often work for hours or days, sometimes even weeks, on a program without ever running it. This is only possible when 99.9% of all errors immediately caught by the compiler (or IDE). Also, I document everything that I do extensively with Javadocs or similar mechanisms. When I write in dynamic languages, I usually start writing the static type annotations ("//array of string") as comments, without having the benefit of using code completion and refactoring. So effectively, for me, dynamic languages mean more typing rather than less.

Because as you think about creating your video (which is almost necessarily many times bigger than any image in file size) you're supposed to think: "what about all the spoken word and textual content of this video file, why can't I access it like any other online text?" in the same way you do today when confronted with large amounts of text in an image, but strangely people don't think that today about video because video accessibility isn't part of the standard web practice (yet).
My take:

Nutrition is probably only about 20% of the picture. You should be exercising, meditating, stretching, sleeping well, etc.

Humans can survive on all sorts of different foods. I think the optimal diet contains lots of fresh whole fruit and veggies, kale, and a bit of meat and fish.

Listen to your body. Does a food make you feel sluggish? Drugged? Energized? Strong?
It may be "pretty well established" but I don't believe it.

I read your link, and you are basing memory based on an experiment that is unlikely to have strong emotional impact for the kid. Without strong emotional impact, I wouldn't expect memory to last. That says nothing about what can happen with memories of more impactful events.

Here is an anecdote that happened with my son. Before he was 7 months he spent several hours a week in a mommy and me run by one Tandy Parks. Then we moved and he never saw her again. When he was 1 1/2 we had the opportunity to drop in on that mommy and me class. Despite normally being shy, he quickly found his way to her lap, which is most emphatically not a behavior he shows with strangers.

Going back to your link, the researcher says, "Most single experiences before age 8 months, unless they are very emotional or painful, are probably lost." That qualification makes perfect sense to me, and is very relevant to the example at hand. My son had very emotional interactions with Tandy, and so he still had associations with her. I'm sure he wouldn't have remembered a toy from the same period. And particularly not a toy he had limited interactions with.

Furthermore the researcher has another good reason to put that qualification in there. A number of research studies that demonstrated that strong pain can alter responses to pain months to years later, even in very small infants. This is clear evidence of memory. In particular these studies have focused on comparing the responses of circumcised and uncircumcised males to shots. Many groups of researchers have demonstrated that circumcised males have more trouble with pain at 6 months. Some research suggests it may still apparent as late as 2.5 years.

If you're talking about conscious and structured memories, they appear to start much later than 1. See http://en.wikipedia.org/wiki/Childhood_amnesia for more on that topic. Bringing it back to my son, at 5 he shows no conscious memories of things that happened when he was 2 (though he still has positive associations with things we did together), but he has some memories from when he was 3, and a lot of very specific memories from age 4.
and what kind of leader do you think Warren "I don't pay enough in taxes" Buffet would be? And certainly, if you needed to keep the college-educated bleeding-heart middle classes and upper middle classes on your side, you would be forced to use tactics even less effective than what the us military currently uses in the middle east, which from here look pretty ineffective.

Hell, look at Gates; a guy who could almost be called bloodthirsty as a businessman, ends up donating some huge portion of his fortune to some feel-good charity.

I just don't think those guys have what it takes to be a Saddam. Even if they did; being ruthless and having a matériel and technology advantage is not always enough. Look at how Afghanistan kicked the crap out of the USSR. This wasn't 'cause the USSR was afraid to wipe out villages with it's vastly superior armament... this was because with currently available weapons, it's damn hard to occupy a country that doesn't want to be occupied.

gah... I dated a chinese girl, and she would discuss that with me when she got sick. It feels like folk medicine, the decision of what makes something 'hot' or 'cold' and so on seemed so arbitrary.

Scott Aaronson adds $200K to prize money if P≠NP proof correct
I don't agree with Bill, hardly all the issues related to the transition from the current model to something full web-based could be solved in 5 years.
I've personally witnessed from the inside the first experiments with online based univ teaching here in Italy(maybe not too relevant), and the result had the word failure plastered all over it. The initial enthusiasm, the progressive difficulties in keeping the students engaged that could never be addressed(new media-> unexpected problems) and lastly what i think could be considered a failure, students with definitely worst degree and that started dropping out.
Quality free material will be increasingly available for sure, but for a typical student is not easy to maintain the consistency needed to study this way. Similarly, universities will have a hard time refactoring their curses to provide something usable/meaningful/useful.

What instead is already evident is the success of web-based courses not related to degrees, small packeted courses on a single subject that target young or not so young adults that want to learn a new language or other stuff.
As you know there are a lot of interesting start-ups in this area.
I only recently realized* and internalized the fact that I don't need to have children. The social pressure to do it is enormous, even if it is not explicit. This article is yet another data point that it is not a good idea to have kids unless you actually want to.

I'll make an educated guess... the advancement is knowing that if you make a machine that can bruteforce 6 sides x 2 turn directions, you can stop searching once a 20th movement is not enough to get the cube solved, and in the worst scenario, you will check ( 6 x 2 )^20 movements in total. I think that scores as test cases :P

There's something like that (though on a different timescale) called Christmas Club accounts. You can deposit money but you can't take it out until December. I understand it was quite popular in the 70s. The idea is to force yourself to save enough for holiday shopping.

I'm totally fascinated by commitment devices like that. I've been compiling a list of them here: http://padm.us/akrasia

This is an introduction to programming using Python. The author did another version using C++:

http://www.greenteapress.com/thinkcpp/

but, for programming newbies, I strongly recommend the Python version (and so does the author).

For programmers who want to learn Python, I'd recommend:

1) Dive into Python 3: http://diveintopython3.org/

2) Google's Python Class: http://code.google.com/edu/languages/google-python-class/
We would know from the proof that such algorithms would exist, and possibly get a method from the proof as to how formulate them.

Teeth serve two purposes- catching and chewing/ripping/tearing.

Long fangs are for catching. Cats don't really chew food, nor do snakes. Both rely on their teeth to stab and hold prey, which is why they are sharp like needles.

Our cutting teeth are for slicing and chewing- in other words, processing the meat after it's been caught. The 'massive predator fangs' take care of catching it, but have you ever eaten meat without biting off a piece, ONLY cutting it up into little bits and chewing it? There's a reason that's relegated to high society, it's not worthwhile for everyone else, and it'd be ridiculously hard with stone tools.

I think you're confused -- they went the other way around, using the algorithm to find the optimal number.

Search techniques that can quickly solve any cube with a small (near-optimal) number of moves have been known for a while, mainly due to the work of Kociemba: http://www.jaapsch.net/puzzles/compcube.htm#kocal The techniques used are standard AI tree/graph search algorithms with lots of Rubik's cube-specific optimizations.

A few years ago, these methods became good enough to solve almost any cube quickly within 20 moves (which was conjectured to be God's number.) So the algorithm as well as a fast implementation already existed. Here's Kociemba's page http://kociemba.org/cube.htm and here's an iPhone app with a neat twist: you can photograph your physical cube to solve it http://www.wired.com/epicenter/2009/01/iphone-app-solv/

What these guys did was to make further optimizations and run it on a cluster to search through all possible position sets. As they say, they can solve about 4000 positions/s (in 20 moves or less) on a single machine.
> You are assuming that a person with a phd is inherently smarter than a person running a hot dog stand.

I'm assuming that if I pick random PhDs and hot dog vendors, I will get a higher average IQ from my random PhDs. Are my PhDs strictly greater in IQ than my hot dog sellers? Maybe, maybe not. But will, say, 99% of my PhDs have a higher IQ? I'd bet on that number or something like it.

> No, people from 2000 years are just as smart as you and me.

No, they were not. There were a few geniuses back then, the ones we still read and write books about. All few tens of thousands of them out of billions. But the average was vastly below the modern-day.

The environmental causes alone are legion: lead plumbing, no formal schooling (worth something like 5-10 IQ points), rampant parasitic diseases of every conceivable sort, irregular or poor nutrition with nutritional deficits (protein deficiency damaging early neurological development - low myelination of nerves, iodine deficiency, etc.), medicine that would kill most patients...

Your only valid points are that IQ is not perfectly correlated with success and that it varies within every group. This is not news to anyone who has done even a little reading on the topic.
Have you ever carefully examined how hard it is for a vegetarian, or especially a vegan, to get all the right nutrients?

I got news for you, primeval man did not have the discretionary ability we have today in our food.

Protein is an excellent example. The primary sources for vegans are nuts/seeds, and legumes. If you can't cook, it's very hard to eat legumes- have you ever tried eating a raw pinto bean? They are literally hard as rocks. Plus they cannot be found across the globe. Nuts and seeds are very seasonal, leaving man high and dry in certain seasons, and it's much much more of a challenge to harvest 6+ oz of nuts every day than it is to buy a jar of them at the store.
"I get anxious"

In my highly unscientific opinion: That's worse for you than anything you could ever eat.

Stop eating when you are full. Avoid excessive junk food. Try to eat fruit and vegetables more than occasionally. Reserve the cheeseburgers and onion rings for the celebration of Friday. Hold that celebration with friends and family more often than just Friday. Drink some wine or a beer. Laugh about it. Don't dwell on anything.

Even if you don't live longer, you'll live better.

That's very interesting. That concept also exists in Indian, Pakistani and (I believe) Persian culture.
Hmm I don't know if its arbitary, I can tell if a food is 'hot' or 'cold' just by eating it, even if I've never seen it before.

For me, only eating 'hot' foods means I get more ulcers, so I am always watching out.

I re-read the whole article once more, and I think I may be not as confused as you make it out to be.

They explicitly state that they did not generate the optimal number of moves for each of those inputs, only a number <= 20.

So, the question is, does a god-algorithm exist or does it not, and how will this help in finding such an algorithm?
I got my numbers wrong thanks to an early morning typo... 800GB bandwidth per month, not 800MB.

Of the options recommended:

Max CDN = $39.95 per month deal (1TB), usually $99.95 = Same price as DIY on the deal, or more expensive normally.

SoftLayer = $140 per month (1TB) = More expensive.

CacheFly = $299 per month (2TB) = More expensive and have to upload files to server.

Rackspace CloudFiles = $176 per month (based on current 800GB bandwidth alone - other costs not yet factored in) = More expensive.

Amazon CloudFront = $131 per month (based on current 800GB bandwidth alone - other costs not yet factored in) = More expensive and you have to upload files to the server.

So yeah... DIY looks substantially cheaper. There's still a big gap between small site and large site. For a few days of my time I can easily save myself a lot of potential cost as well as speed up my website. I can't really see why I wouldn't set up my own CDN.
Here's the clue to why doing this made sense: "But import duties greatly reduced the profit margins of importers."

It's as if the shoes were smuggled into India in plain sight. Presumably the cost of buying the 'useless' shoes at auction came to less than the import duty.
You missed it.

The profit comes from the fact that the money paid in step 3 is less than what would have been paid in import duties had he collected the shoes in step 2. And then, having successfully imported shoes at below the cost that other entrepreneurs were capable of getting, he was able to resell those shoes at below market rates and still have a higher profit margin.

If he paid more for special handling, that would have been covered. If the shipments were big enough, then postage is based on some combination of weight and volume. This is unchanged.
Our bodies are extremely resilient and can take a beating from crappy foods. That's why such food 'does not kill us on the spot'.

That's the justification. If that suits you, that's fine--it's your health.

> have you ever eaten meat without biting off a piece, ONLY cutting it up into little bits and chewing it?

Uh, pretty much every day? I'm pretty sure that's what pre-humans did, too. They butchered, cooked, and cut it up. Dentition is irrelevant.

A visit to Wikipedia actually confirms this story (I was sure it was a joke before): http://en.wikipedia.org/wiki/Typhoon_class_submarine#Descrip...

"Typhoon class submarines feature multiple pressure hulls that simplify internal design while making the vessel much wider than a normal submarine. In the main body of the sub, two Delta class pressure hulls lie parallel with a third, smaller pressure hull above them (which protrudes just below the sail), and two other pressure hulls for torpedoes and steering gear."
Your original question was whether they have an algorithm to solve in <= 20 moves or not. I answered that.

Now you changed your question to whether they can solve each position optimally or not. Fine.

Why don't you re-read the article once again? They state that they can solve random positions optimally at the rate of 0.36/sec, in the same table where they say 3,900/sec for solving it in 20 moves or less.
The proof in questions attempts to show that P != NP, contrary to the title here.
Setting up Google Alerts for your site (micro-how-to)
I clarified my question because I think that it wasn't clearly stated, and I marked my edit to make sure that it was clear that I did so (unlike others here).

As for the re-reading, they don't solve the positions optimally, they brute force them so they're not in the possession of a god algorithm as far as I can see, they're using a highly optimized search strategy and that's a different beast.

A 'god' algorithm would take the faces as an input and would produce the minimal number of moves without a search component. So each configuration would be processed to give you the next without evaluation of 'wrong' moves or back-tracking.

That would be the 'god' algorithm. Anything else is (highly) optimized search.

I think you're making something of a sweeping generalisation here. Jobs have moved overseas because labour is cheaper - true. Jobs have also been automated. So yes, some jobs have been "lost". But this is not a bad thing. This is progress. Hopefully these jobs get replaced by new jobs. 20 years ago there were no web designers - the web didn't exist. Now there's millions of web designers. How is this possible, where did these people come from? Education, training. This is vital for any advancing economy.
