Just another toy for the wealthy. I'm still looking for something like the Moller Skycar with auto-pilot. Getting a pilot's license is too hard/expensive/takes too long for it go mainstream. It would also be nice if it u

Ah the vocal minority. As Henry Ford said, "If I had asked people what they wanted, they would have said faster horses". Don't let a few troglodytes stand in the way of progress. Look at your analytics for approval/disap

If you want to write modules for Drupal/Joomla, they are written in PHP, which is similar to C. Ruby on Rails is known for being easy-to-use. You should learn Javascript no matter what server side language you choose. Python is a good

Looks nice. Too bad it requires backbone and rivets...

I think the BIG is an interesting idea, but I'd like to see some hard evidence that it works before we implemented something this large nationwide. The government should do a controlled test. You could go somewhere like India, randomly

Does anyone have any examples of areas where neural networks beat out statistical based methods, other than maybe image recognition? I can't even think of another major area where they dominate. - Search engines use algorithms, not neu

They hand pick spam sites and remove them every day... There is an entire department dedicated to detecting spam.

They will manually remove sites for spam in their own search engine, but they don't ban the associated Adsense account. In other words, they are more than happy to pay you to spam other search engines.

You've been drinking the Google kool-aid. Google has always been the primary financier of web spam on the Internet. They knowingly profit from Adsense on spam sites. If they wanted to, they could end web-spam over night by banning Adse

Why do you think paid search campaigns don't need more detailed data? Why do you seem to think SEOs shouldn't get data?

Patents are a legal monopoly. To say a company has a monopoly just means that it is extremely difficult to compete. In search, the market naturally created a monopoly. Not only does google have twice the market share of anyone else, they li

That's only for the U.S. In all but a few foreign countries, Google has closer to a 90% market share.

It's hard to think of what the lurking variable could be here if you want to make the argument that this is purely correlation and not causation. With Facebook likes, that could also indicate overall traffic levels or other popularity-

When sites.google.com first came out it ranked their own pages much better than a new site (they've since turned it down a bit). Many tech reporters say the only reason they use Google+ is to post stories on there because Google will r

It still seems like ET3 has a much better design. It's simpler, more efficient, faster, and has fewer moving parts (that can break). The only down-side would be the 6% royalty you'd have to pay. As far as proposed routes, train st

Are there any real studies on the "corrosive influence" of porn on children? I'm pretty sure every young teen boy has seen porn these days. The only actual studies I'm aware of say that porn reduces actually violent sex

I wonder if these shifts disproportionately affect the less intelligent. By definition, half the population is below average. If the jobs being destroyed are low skill, and they are replaced with jobs in math/science/tech, people

You can create a chaotic map with a simple formula, but those don't appear often in the real world. Give me the formula for the weather, or to predict the next earthquake, or to model turbulence. If the stock market movements were norm

Yes, you can predict the amount of randomness in a normally distributed system. If you could not, standard deviations would have no meaning, and all branches of statistics built thereon would be false. In chaos theory, the best you can hope

by JDDunn9 13y ago
You missed the whole point. Randomness exists in both normal and chaotic systems. The difference is that in normally distributed systems, randomness can be predicted.

Scientists are not split on those issues. Uneducated people disagree with the scientists. Big difference. If economists have a handle on things, why did the IMF have to apologize to Greece for giving them bad advice? Why did the Black-Schol

by JDDunn9 13y ago
The basic problem with economics is mathematical. Economists keep acting like the economy is normally distributed when it is not. For example, the "Black Scholes Model", assumed that the system was normally distributed, differenti

These surveys don't/can't measure customer satisfaction. They suffer from self-selection bias. If only 2% of your visitors actually submit the form, you can only make generalizations about those 2% of your visitors. You canno

I agree. Who ever said, "Boy I wish I could manufacture that in my house"? Plastic goods are already cheap, so what does this save me? 2 days waiting for my Amazon order? Revolutions happen when you drastically reduce costs, or increase fun

All hard sciences have sufficient evidence to back them up. Whether it is mathematical proofs, experimental evidence, etc. There is no hard evidence for the social sciences. Astronomers can predict orbits with incredible accuracy millions o

Consumer marketing would be a good example of something that has no long-term benefit because society changes too often. Marketing techniques that work in one decade won't work in the next. Because of this, marketing isn't cumulative. Our k

These are the kind of studies that make me think social-psychology is just a psuedo-science. If you want to understand human-nature, read Shakespeare over Freud. If you want to influence people, read Dale Carnegie over B.F. Skinner. I'll gl
