Thanks.

Thanks for the data point. Did the square roots render over the quantities. I'll have to check browsers, but Opera was a no go and Chrome is okay but not great.

This might be nice, but from what I can tell it does seem to work very well:

At least before, people could read this.

I guess you don't understand proper subset. He was implying that all pedophiles are gay (or that all gay people are pedophiles which I'll give him the benefit of the doubt that he wasn't saying that).

It is not okay to imply that homosexuality and pedophilia are the same thing.

Well said. I think the biggest break he's ever had was Steve Job's endorsing one of Gruber's posts as Apple reasoning.

I don't know if it is. It's pretty shocking to me how different these subjects can be. And the grass is always green on the other side.

>Allegedly unrealistic assumptions about rationality and information are gleefully (and sometimes unfairly) ridiculed.

These are more than allegedly ridiculous, they are ridiculous. But, I'm sure constant harping on this point would be very annoying.

Beinhocker's book is interesting because it lays out several different types of evolution that a taking place that contribute to economic growth. He also lays out some interesting mathematical models that people are using.

I'm am genuinely curious as to how much math you've been exposed to in your econ courses.

That there is a field called Innovation Economics basically proves my point. As it states in the linked it is fact quite different from standard economic theory.

You state in another post that English is your second language. When you say 'textbook definition' you are implying canonical usage, not there exists a textbook that I use that defines this.

>None of the textbooks in economics (HS and undergraduate courses) or economists I have read assume this to be true, or even a useful approximation for most markets.

That is really striking. You have never taken microeconomics? Never dealt with the efficient market hypothesis? Ever taken a economic theory class? This is possible since European approaches to economic education differ quite a bit from American ones. But it is extraordinarily difficult to have mathematical models of markets where participants have informational asymmetries.

>Of course they are, for example in every study ever written on globalization, the structure of corporations, corporate governance or insider trading. Or is there some special definition of the terms you're using?

These things are not economics per se. They are interesting things to study, and yes they involve networks. But just because they exist does not mean they are subjects in standard economic textbooks.

Yeah, I'm with you. Unfortunately people like to take economic theorems off the shelf without looking at some of the assumptions.

>Changes in institutions/networks/interconnectedness etc. as described in the Beinhocker book is innovation according to the economic textbook definition.

Innovation is hardly considered in economics at all. As is alluded to in the essay, it is considered an external variable. This is a huge point of Beinhocker's that economic theory is based on a physics of equilibrium. Bad idea.

Networks and interconnectedness are not considered at all in 'textbook' economic definitions. When agents already have perfect information, why do you need to meet others?

I'd love to see a textbook definition of innovation that comes close to what you have asserted here.

Some interesting stuff in there but it's a bit scatterbrained and too obsessed with coming back to libertarian dogma.

There is a line of argument that says that most growth comes from innovation. While some of it surely does, I think interconnectedness is much more important. It's sad this just turns into ideas having sex in the article. But then again lots of stuff is important in how inter-human relations develop over time. It's foolish to obsessively attribute much of the growth of the economy to one thing.

For a scatterbrained, but much more interesting and less dogmatic, rethinking of economics theory I recommend Origin of Wealth by Eric D. Beinhocker.

Nah, unfortunately that algorithm does not magically make bitmaps scale. The image example they gave is grossly misleading. It works well on certain types of sparse information in Fourier space.

Yeah, nothing there or in related articles disputes the assertion that they invented PageRank. Sure, they did it in a community that was developing similar ideas, but they built and developed it.

I'd be interested to know, but somehow I seriously doubt there were librarians taking eigenvalues of citation networks.

>Google was based on a couple of brilliant ideas (Page rank, text-only ads, massive parallel implementation on cheap hardware) but none of those ideas were original with Larry or Sergey.

Wow. I didn't think someone would claim that Page rank was not an original idea of Larry and Sergey. It generally helps when you are writing a myth busting article to not invent your own.

Yeah with the added constraint that it was a pension that the Dad retired with.

Thanks a lot for the ideas.

I'll have to do some benchmarking, but I doubt that javascript will be able to do this any faster. Each dot can take quite a few flops to get calculated. I would like to prototype a NaCl viewer though. I need to do some tricks to make the transitions smoother.

Cool, I'm working a math one when it goes it will be posted at:

Alright technical details. I used GWT for the front end. Mainly because I like working in an IDE, and because I don't have to worry about browser quirks (although I need to tweak the css some.)

All the tiles are generated by a single servlet. You can sort of tell how it was developed by the way it is called:

0.23x0x14.png?...

The first number is lambda. Next is the zoom. The next number is the id of the tile. Each zoom level is broken up into (4*2^zoom)^2 tiles. I need to break the x and y coordinate into separate pieces as this scheme starts hitting integer overflow errors around zoom 15.

You may notice that the PNG files are rather small. This is because they are index based on a 256 color palette (but with 24 bit colors). I wrote my own PNG file creator for this.

This is all in Java for the most part. I prefer ruby for putting something together, but Java had all the things I needed for the most part and the speed of it is really nice for this project.

Happy to oblige. However, technical could mean:

1. Implementation details 2. Math details

Let me know 1, 2 or both and I'll fill you in.

Well then Microsoft must be kicking serious ass in the space too because they have spent a lot more.

I am super skeptical of any company that spends a lot of money to break into an area that isn't in their 'core competency'. Apple has shown they only know how to offer online services for a high subscription rate. It'd be interesting to see if they can offer anything decent for free or a low price point.

I'd just be interested in knowing what sort of bias would it have. How would the government like new science to look? Would it be at all productive to fake experiments?

The government has its issues, but funding science is a great thing. Sure, I'd like for less money to be controlled by the pentagon. But I'd love to see even money spent on basic research.

>Of course federal funding distorts science. How could it not? It's naive to think otherwise. Politics pervades all the other areas of government spending. Are you saying that scientists and their funders are somehow superior to everyone else? That they have a special gene that makes them bias-free?

This is pretty sad and pathetic. If you are so confident, please head over to the NSF and go through grant proposals. Let us know when you prove your case with evidence that is so obviously true to you.

>Why don't government-funded scientists study whether thousands of math teachers can be taken off government payrolls and replaced with Khan's videos?

People do study different methods of teaching. I'll think you'll find that videos are no substitute for human interaction though.

Your other commentary on various things is just rather confused, but not lacking in certainty. Congratulations on becoming a fountain of truth.

Probably right. However, the post outed his as an ideological opponent of government action (with a little fatalism thrown in). This would place him firmly in the denier camp according to the original article.

LOL?

Yes, virtually all basic research is federally funded. Does it distort science?

Nutrition is not at all easy to do as science because doing research with humans is not considered ethical by society. I think it's something we need to address, and it seems short sighted to me.

Your example is not at all convincing evidence for you rather sweeping thesis.

It's sad that this is being up-voted as it is incredibly misleading and a conspiracy theory to boot:

>#1 mainly intended to achieve a long-standing but tactically-shifting goal of governments to control capital

No, global warming is not a government plan. It is an area of scientific consensus that has emerged from the work of thousands of individuals in many countries. Most mainstream solutions to dealing with global warming have absolutely nothing to do with controlling capital. In the US, we constantly bend over backwards to makes sure private enterprise controls lots of stuff (even the alternative energy technologies that are being heavily subsidized in R&D and production).

>you will likely find that even the most committed climate changists are not expending their own resources to short Florida coastal real estate on the weight of their beliefs.

This statement is at best tremendously disingenuous and at worst an amazing attempt at self-delusion. There is no good way to short houses. (Getting CDSs on mortgage backed securities is possible but there are no houses on the coast securities. Shorting those wouldn't even help, as mortgages will be paid off before the sea rises enough). Also, all the global warming sea rise predictions are on the order of decades and centuries. What highly knowledgeable scientist in there late 30s or 40s will make at bet that will be resolved when they are dead?

I'll bet you any amount of money that we will have a Korean president by 2150. Don't believe me? Unless you do, you'd better make a bet with me.

I think you making a totally fair point about the symmetry of the situation. However, I think his attitude (and by symmetry probably hers too) is an unhealthy one. He can always think, "were it not for her attitude I, errr we, could be more successful". This is quite a negative thought to hold in your head with someone that you should have an amicable rapport with.

>You should not think about someone's happiness, that does not also think about your own.

I guess you can live by that, but I certainly don't like the dynamics of this towards the limit. If somebody is hurting I don't mind trying to say something. Suffering isn't cool.

I know they don't in Korea. Hangul lends itself to typing.

1. Please show me a state with a per capta gdp that approaches one from the third world.

2. Your wife may be forcing you to stay in state to be with her. Either celebrate your marriage and don't bitch about how it's bringing you down or move on.

No it's not. I'm not exactly sure why, but issues are dated a week ahead. Visit your local bookstore/magazine stand if you don't believe me.

Yeah because every time I say the f-bomb on the phone there party on the other end hears a bleep.

Let's be serious about what the FCC could do when regulating the internet. Anything they try to do will have to pass 1st amendment muster.
