Comment How it works (Score 5, Informative) 133

As the page is slashdotted, I just wanted to post how it is done here:

For GMail, he added an image to his own GMail account, which he set to "visible for everyone". On his own site he added an invisible img and tries to access the image in his GMail account. He then triggers a javascript function depending on the outcome of the img inclusion (onload or onerror), so he can make the decision, if the visitor of his website is logged in to GMail.

For Facebook, Twitter and Digg he uses http status codes. He tries to access some URL (https://www.facebook.com/imike3) via javascript and depending on the status code he gets, he can decide whether you are logged in or not. This attack doesn't work with IE or Opera, because they do not trigger the onload/onerror events when receiving invalid js.

Euler's Partition Function Theory Finished 117

universegeek writes "Mathematician Ken Ono, from Emory, has solved a 250-year-old problem: how to exactly and explicitly generate partition numbers. Ono and colleagues were able to finally do this by realizing that the pattern of partition numbers is fractal (PDF). This pattern allowed them to find a finite, algebraic formula, which is like striking oil in mathematics."

Polynomial Time Code For 3-SAT Released, P==NP 700

An anonymous reader writes "Vladimir Romanov has released what he claims is a polynomial-time algorithm for solving 3-SAT. Because 3-SAT is NP-complete, this would imply that P==NP. While there's still good reason to be skeptical that this is, in fact, true, he's made source code available and appears decidedly more serious than most of the people attempting to prove that P==NP or P!=NP. Even though this is probably wrong, just based on the sheer number of prior failures, it seems more likely to lead to new discoveries than most. Note that there are already algorithms to solve 3-SAT, including one that runs in time (4/3)^n and succeeds with high probability. Incidentally, this wouldn't necessarily imply that encryption is worthless: it may still be too slow to be practical."

Arx Fatalis Updated, Released Under GPL 153

Kevin Fishburne writes "According to WtF Dragon at Ultima Aiera, 'The long and short: Arkane Studios have released what is probably going to be the final patch for their Ultima Underworld-inspired game (which, indeed, they tried to license as the third entry in that series), Arx Fatalis. They have also released the source code for the game. That's right, the complete source of Arx Fatalis is available for download.' The readme notes that the original game installation is required in order to play the compiled game, as the data files are certainly still copyrighted. Linux is in need of a good FPS dungeon crawler, though the code will need a hell of a lot of cleanup as it's a VC8/9 project and uses DirectX (ugh...)."

Why Sony Cannot Stop PS3 Pirates 378

Sam writes "A former Ubisoft exec believes that Sony will not be able to combat piracy on the PlayStation 3, which was recently hacked. Martin Walfisz, former CEO of Ubisoft subsidiary Ubisoft Massive, was a key player in developing Ubisoft's new DRM technologies. Since playing pirated games doesn't require a modchip, his argument is that Sony won't be able to easily detect hacked consoles. Sony's only possible solution is to revise the PS3 hardware itself, which would be a very costly process. Changing the hardware could possibly work for new console sales, though there would be the problem of backwards compatibility with the already-released games. Furthermore, current users would still be able to run pirated copies on current hardware." An anonymous reader adds commentary from PS3 hacker Mathieu Hervais about Sony's legal posturing.

How To Be Popular On Facebook, Quantified 97

Hugh Pickens writes "Network World reports that Facebook has just released an analysis of the word usage for about one million status updates from its US English speakers with the words in updates organized into 68 different word categories based on the Linguistic Inquiry and Word Count (LIWC)--a text analysis software program that calculates the degree to which people use different categories of words across a wide array of texts. The results? To be popular on Facebook all you have to do is write longer status updates, talk about music and sports, don't be overly emotional, don't talk about your family, don't refer to time and use the word 'you' a lot. Facebook's study also confirms something that bloggers and Fox News have known for years: negative comments produce more online activity. Sure, Facebook users might click the like button more often on updates expressing positive emotion. But Facebook found you can't beat negativity for user engagement, as dismal status updates garnered more comments than positive ones."

8-Year-Olds Publish Scientific Bee Study 174

flintmecha writes "A group of British schoolchildren may be the youngest scientists ever to have their work published in a peer-reviewed journal. In a new paper in Biology Letters, children from Blackawton Primary School report that buff-tailed bumblebees can learn to recognize nourishing flowers based on colors and patterns. The paper itself is well worth reading. It's written entirely in the kids' voices, complete with sound effects (part of the Methods section is subtitled, ''the puzzle'duh duh duuuhhh') and figures drawn by hand in colored pencil."

Submission + - Ellsberg supports wikileaks (ellsberg.net)

wierd_w writes: Daniel Ellsberg: “EVERY attack now made on WikiLeaks and Julian Assange was made against me and the release of the Pentagon Papers at the time.”

Due to the recent debates over the pros and cons between the wikileaks releases and those of the historic "Pentagon papers", Journalist Daniel Ellsberg, who released the pentagon papers in 1971, has written an editorial on the subject declaring that he rejects the mantra of “Pentagon Papers good; WikiLeaks material bad", and that further “That’s just a cover for people who don’t want to admit that they oppose any and all exposure of even the most misguided, secretive foreign policy. The truth is that EVERY attack now made on WikiLeaks and Julian Assange was made against me and the release of the Pentagon Papers at the time.”

Submission + - New NASA Model Refutes Global Warming Alarmists (theregister.co.uk)

Dialecticus writes: According to an article by Lewis Page at The Register, NASA says that most theoretical models of global warming fail to take into account the cooling effects of how plant life would react to higher CO2 levels in the atmosphere. NASA's new model reportedly indicates that even something as extreme as a doubling of current CO2 levels would only result in a 1.64 degree Celsius increase in overall global temperatures, with temperature increases over land being even less than that. The article does not specifically mention whether increased photosynthesis would have a natural regulating effect on CO2 levels due to the commensurate increase in the rate of naturally occurring carbon sequestration.

Submission + - Google Hopeful Nokia Will Adopt Android For Phones (computerworld.com)

CWmike writes: A Google executive said this week that he's hopeful that Nokia will decide to adopt the Android platform after new leadership at the world's biggest mobile phone manufacturer finishes a new evaluation of smartphone options. Comments by Andy Rubin, vice president of Google's mobile platforms, during a conference this week prompted speculation about Nokia's upcoming smartphone plans. Analysts have expressed continuing concerns about Nokia's abysmal smartphone performance in the U.S., and are hoping that the company's recently appointed top leadership can change the downward trend. While Nokia's Symbian OS is still the world's top mobile platform, it's widely seen as declining in importance. In fact, Nokia has teamed with Intel to create a newer open source Meego mobile OS platform.

USB Is the Devil's Connection 474

Jamie handed us Satan's Data Connection. You see, sane and rational human being, the USB logo is actually in the shape of a trident, and the obvious action to Evangelical Christians in Brazil is to ban its use. Hopefully they don't mispronounce SCSI and find themselves lusting after their PCs.

Failed MMO APB To Be Resurrected As Free-To-Play Game 90

Two months ago, we discussed news that Realtime Worlds' action MMO APB closed its doors only a few months after launch, when it became clear that player interest and subscriber numbers couldn't begin to recoup the massive development cost. A few days ago, a company called Reloaded Productions, owned by free-to-play publisher GamersFirst, acquired all the rights and assets to APB. The company plans to relaunch the game as APB: Reloaded in the first half of 2011, abandoning its unusual business model in favor of free-to-play accounts supplemented by microtransactions and premium services.

Stuxnet Was Designed To Subtly Interfere With Uranium Enrichment 334

ceswiedler writes "Wired is reporting that the Stuxnet worm was apparently designed to subtly interfere with uranium enrichment by periodically speeding or slowing specific frequency converter drives spinning between 807Hz and 1210Hz. The goal was not to cause a major malfunction (which would be quickly noticed), but rather to degrade the quality of the enriched uranium to the point where much of it wouldn't be useful in atomic weapons. Statistics from 2009 show that the number of enriched centrifuges operational in Iran mysteriously declined from about 4,700 to about 3,900 at around the time the worm was spreading in Iran."
