Comment Re:What 30%? (Score 1) 467

I would say most likely this is a combination of confirmation bias and the fact that they do in fact track what you are buying.

You only remember when you see the coupon around your wife's period, even though you are probably seeing them all the time.

I never claimed they don't track what you are buying, simply that they are not going to extrapolate enough from their data to be able to advertise lipitor based on how much beef you eat. This is a much bigger stretch than advertising hygiene products because you buy other, similar hygiene products, which I'm sure they regularly do.

It is true that isn't illegal, just non-compliant. Which I don't think is a major point in this case since it is still something the merchant cannot do.

I'm sorry that the poster didn't have the time or inclination to look anything up, but without any sources or credentials one has no reason whatsoever to believe anything being written anonymously on the internet. Anyone can easily claim they are an authority on any subject.

You are being a little silly here. When you sign up for the card, they get your address so they can sell it to junk mailers. They do not, however, know your current address if you have moved since getting the card (and I'm sure many people have).

Storing your credit card numbers when you use them via a magnetic swipe is actually illegal, see here for example. So, supermarkets actually cannot store your credit card information.

And finally, the reason the supermarket wants your purchase information is to do analysis of demographics and to better optimize their business. They are not doing the sort of data mining that would allow them to sell you lipitor based on how much beef you eat. You have absolutely no evidence to back up that assertion.

Despite the title, what this article is actually referring to is smartphone sales. That does not include iPods or iPads.

What I find interesting is that despite essentially doubling their iPhone sales since the middle of 2010, Apple is now already a distant second to Android in terms of sales and smartphone market share. This situation is especially remarkable when you consider where Android was 2 or even 1 year ago.

Comment Re:Not Wikipedia's job to be a first publisher (Score 4, Insightful) 240

There is no requirement that something be written about in an academic source to be included in wikipedia. Any reputable source will generally do, including newspapers and magazines in most cases.

Any game that had a substantial influence shaping the development of gaming is worthy of inclusion. That doesn't mean that it won't be difficult to find good sources to back up the argument that it was in fact influential.

That's interesting. Most of the non-geek people I know who still have iPhones are planning to switch to Android when their contract is up. I also know a number of people who have already switched and are much happier than they were with the iPhone. There is a whole family of non-geeks I know who have switched directly from the iPhone to the HTC Incredible and are loving it.

As an Android end user, I must say I haven't experienced the "endemic" reliability issues you are talking about. I think your sentiment that Android is "years and year behind the iPhone" is years and years out of date.

There are several advantages if you think about it. One important property of hex tilings is that as you make the hex grid finer and finer, the distance between two arbitrary points on the grid approaches our standard (Euclidean) distance measure. Square tiles do not have this property. (Think moving diagonally; no matter how fine the grid is it is always faster to move diagonally than horizontally or vertically.

Another advantage is in combat; forming defensive or offensive lines will work better as the distance between a tile and any adjacent tile is always the same. In the context of Civ, this also makes a lot more sense for things like the city radius.

Overall, it is just a much better system.

Comment Bathing the cosmos with infrared light? (Score 3, Informative) 139

The summary says it will be "bathing the cosmos with infrared light". What is this supposed to mean? The spacecraft will be detecting light, but will not be emitting it in any substantial quantity. In fact, WISE will be emitting very little infrared light at all (even for a spacecraft), as it is being kept cool for the next 10 months or so with an onboard supply of solid hydrogen.

America's Army Games Cost $33 Million Over 10 Years 192

Responding to a Freedom Of Information Act request, the US government has revealed the operating costs of the America's Army game series over the past decade. The total bill comes to $32.8 million, with yearly costs varying from $1.3 million to $5.6 million. "While operating America's Army 3 does involve ongoing expenses, paying the game's original development team isn't one of them. Days after the game launched in June, representatives with the Army confirmed that ties were severed with the Emeryville, California-based team behind the project, and future development efforts were being consolidated at the America's Army program office at Redstone Arsenal in Alabama. A decade after its initial foray into the world of gaming, the Army doesn't appear to be withdrawing from the industry anytime soon. In denying other aspects of the FOIA request, the Army stated 'disclosure of this information is likely to cause substantial harm to the Department of the Army's competitive position in the gaming industry.'"

No, he is right. The reason you can't always get close to 100% is because of something called Carnot efficiency.

Carnot Cycle

However, in this situation, that doesn't apply. There is no reason you cannot collect very close to 100% of the energy from braking using your regenerative braking system. There will of course be some loss due to efficiency in the air resistance and rolling resistance. Also, current regenerative braking technology doesn't apply enough force at slow speeds to stop the car in a reasonable manner, and so is quite inefficient at slow speeds. There is nothing fundamental preventing it from being much more efficient, however.
