Nerval's Lobster writes "Software developer Jeff Cogswell is back with an extensive under-the-hood breakdown of Facebook's Graph Search, trying to see if peoples' privacy concerns about the social network's search engine are entirely justified. His conclusion? 'Some of the news articles I've read talk about how Graph Search will start small and slowly grow as it accumulates more information. This is wrong—Graph Search has been accumulating information since the day Facebook opened and the first connections were made in the internal graph structure,' he writes. 'People were nervous about Google storing their history, but it pales in comparison to the information Facebook already has on you, me, and roughly a billion other people.' There's much more at the link, including a handy breakdown of graph theory."

Frequent contributor Bennett Haselton is still thinking about prediction markets, and giving away money. He writes: "In an article last December I described a problem with prediction markets, where even markets with cap on betting limits could be manipulated by a single trader willing to spend a lot of money to distort the marketplace odds. So I offered a $100 cash prize to be split between readers who collectively came up with the best solution to the problem. Here's an idea that I think would work." Read on for the rest.
New submitter jdela writes "Finnish Minister for Justice Anna-Maja Henriksson backs expanding FInland's child pornography blocklist to also include websites with animal porn and largely-undefined 'violent pornography.' Her proposal does not have the unanimous backing of the Finnish government, with Minister of Interior Päivi Räsänen doubting the need to expand pornography blocks. Under current law, adopted in 2006, the Finnish NBI maintains a blocklist of foreign sites linked to child pornography. This blocklist is enforced on Finnish Internet users."
chicksdaddy writes "To paraphrase a quote attributed to F. Scott Fitzgerald: 'Rich countries aren't like everyone else. They have less malware.' That's the conclusion of a special Security Intelligence Report from Microsoft, anyway. The special supplement, released on Wednesday, investigated the links between rates of computer infections and a range of national characteristics including the relative wealth of a nation, observance of the rule of law and the rate of software piracy. The conclusion: cyber security (by Microsoft's definition: low rates of malware infection) correlated positively with many characteristics of wealthy nations – high Gross Income Per Capita, higher broadband penetration and investment in R&D and high rates of literacy. It correlated negatively with characteristics common in poorer nations – like demographic instability, political instability and lower levels of education.'"
ananyo writes "How open do researchers want open-access papers to be? Apparently, not that open — when given a choice of licenses, most opt to limit the use of data and words in their open-access publications, according to figures released by the open-access journal Scientific Reports. Since July 2012 the journal has been offering researchers a choice of three types of license. The first, most liberal license, CC-BY, allows anyone, even commercial organizations, to re-use it. A more restrictive version, CC-BY-NC-SA, lets others remix, tweak and build on work if they give credit to the original author, but only for non-commercial (NC) purposes, and only if they license what they produce under the same terms (SA, or 'share-alike'). A third licence, CC-BY-NC-ND, is the most restrictive, allowing others to download and share work, but not to change it in any way (ND, 'no derivative works'), or use it commercially. The results from Scientific Reports shows that, for the 685 papers accepted by the journal, authors chose either of the more restrictive licences 95% of the time — and the most restrictive, CC-BY-NC-ND, 68% of the time."
jfruh writes "The MPAA and other entertainment industry groups have been locked for years in a legal struggle against Newzbin2, a Usenet-indexing site. Since Newzbin2 profited from making it easier for users to find pirated movies online, the MPAA contends they can sue to take those profits on behalf of members who produced that content in the first place. But a British court has rejected that argument."
