But any competent marketing department would get the hint when 589,141 out of 668,872 people disliked a proposed change.
You need to poll far less than 30% to get a statistically significant result representing the wishes of those 1,000,000,000 idiots.

"Statistically Significant" doesn't really make sense here...that sort of computation assumes that the people being surveyed are a representative sample of all users.

In this case we've got a pretty strong selection bias going on where people who are most upset about the new policy are the most likely to vote.

Comment Clever Coffee Dripper (Score 1) 584

It's an ingenious little device that's sort of a cross between a French Press and a pour-over filter. You pour the coffee and hot water in a paper filter at the top and let it infuse for a few minutes. Once your coffee's sufficiently strong, you place it on top of your cup, which lifts the stopper and lets the coffee drip out the bottom. For more on this. See http://www.sweetmarias.com/clevercoffeedripperpictorial.php for more information.

An example of Astroturfing on Amazon: http://www.amazon.com/The-Twelfth-Cliburn-Piano-Competition/product-reviews/B000BZ8IA8/ref=cm_cr_pr_btm_link_4?ie=UTF8&filterBy=addFiveStar&pageNumber=4&showViewpoints=0

Of the 35 five star reviews, about 30 were posted in a 1 week period by people who have no other reviews. Of course, each of those reviewers carefully voted up all the previous other 5 star reviews to promote them in the review rankings (so

Comment Re:Sport specific -- fencing (Score 1) 82

For an epeeist, that's really terrific coverage. I know what I'm looking for, and the announcer/color commentary are just a distraction. For a non-fencer, it must have been terrible.

As a non-fencer, I actually found the epee much easier to follow than the other events (mainly because there was no need to worry about right of way). The other events were enjoyable to watch, but I did a lot of taking the scoring on faith/outright ignoring the scoring and just watching the fencing.

Comment There WERE computers involved, indirectly. (Score 1) 170

From the abstract of Tao's paper: Our argument relies on some previous numerical work, namely the verification of Richstein of the even Goldbach conjecture up to $4 \times 10^{14}$, and the verification of van de Lune and (independently) of Wedeniwski of the Riemann hypothesis up to height $3.29 \times 10^9$.

Richstein's work (available at http://www.ams.org/journals/mcom/2001-70-236/S0025-5718-00-01290-4/S0025-5718-00-01290-4.pdf ) definitely involves a computer, and I assume the Riemann hypothesis verification does as well.

Submission + - John Nash's declassified 1955 letter to the NSA (wordpress.com)

An anonymous reader writes: In 1955, John Nash sends an amazing letter to the NSA in order to support an encryption design that he suggested. In it he no less than anticipates computational complexity theory as well as modern cryptography.

In the letter he proposes that the security of encryption can be based on computational hardness and makes the distinction between polynomial time and exponential time: "So a logical way to classify enciphering processes is by the way in which the computation length for the computation of the key increases with increasing length of the key. This is at best exponential and at worst probably at most a relatively small power of r, ar^2 or ar^3, as in substitution ciphers.

Submission + - CNet Download.com bundling adware with OSS softwar (neosmart.net)

An anonymous reader writes: In a recent site update, CNET Download.com listings have begun redirecting product download links for popular freeware and opensource applications to their own "downloader and installer" utility which bundles a number of adware components alongside the requested application and changes the users' homepage and default search engine to Microsoft Bing. Freeware authors are sending CNet cease and desist orders demanding virgin download links, something affected open source developers may or may not be able to do due to FOSS license terms.

Comment The app's a little beside the point (Score 4, Informative) 36

After all, it deals with a graph whose nodes and connections are already known exactly.

The more interesting part comes when you move to a graph like the link structure or underlying router structure of the internet, which is both orders of magnitude larger and changing rapidly -- even if you could take a perfect snapshot of it, by the time you finished analyzing that snapshot the network would have changed quite a bit in the meantime.

What Lovasz has been doing recently with his work on "graph limits" is providing a framework for analyzing such graphs. You can imagine global properties of the network approaching some sort of fixed equilibrium and hope to analyze that equilibrium without actually knowing the details of how the network is changing. I don't actually know if the work has been used in practical applications yet, but the concept goes far beyond just redrawing planar graphs.

Comment How much of a cut are they really facing? (Score 1) 197

In Newport Beach, the library receives roughly $318,000 in state funding (source http://articles.dailypilot.com/2011-01-14/news/tn-dpt-0115-library-20110114_1_library-budget-newport-library-library-funding ). I can't open the Newport Beach budget documents at the moment, but recently the city referred referred to $132,500 cut in library funding as a "2% reduction" in the library's budget (source http://www.newportbeachca.gov/Modules/ShowDocument.aspx?documentid=4738 ).

So by my count the library's facing less than a 5% cut in its budget if every last cent of state funding is cut. And yet they're talking about eliminating books. This smells more like passing the blame to the state and/or trying to get publicity/sympathy rather than an actual budget crisis due to reduction in state funds.
