Hugh Pickens DOT Com writes "Chris Mooney reports at Slate that research conducted by Erin Buckels of the University of Manitoba confirmed that people who engage in internet trolling are characterized by personality traits that fall in the so-called Dark Tetrad: Machiavellianism (willingness to manipulate and deceive others), narcissism (egotism and self-obsession), psychopathy (the lack of remorse and empathy), and sadism (pleasure in the suffering of others). In the study, trolls were identified in a variety of ways. One was by simply asking survey participants what they 'enjoyed doing most' when on online comment sites, offering five options: 'debating issues that are important to you,' 'chatting with others,' 'making new friends,' 'trolling others,' and 'other.' The study recruited participants from Amazon's Mechanical Turk website and two measures of sadistic personality were administered (PDF): the Short Sadistic Impulse Scale and the Varieties of Sadistic Tendencies Scale. Only 5.6 percent of survey respondents actually specified that they enjoyed 'trolling.' By contrast, 41.3 percent of Internet users were 'non-commenters,' meaning they didn't like engaging online at all. So trolls are, as has often been suspected, a minority of online commenters, and an even smaller minority of overall Internet users. Overall, the authors found that the relationship between sadism and trolling was the strongest, and that indeed, sadists appear to troll because they find it pleasurable. 'Both trolls and sadists feel sadistic glee at the distress of others. Sadists just want to have fun ... and the Internet is their playground!' The study comes as websites are increasingly weighing steps to rein in trollish behavior but the study authors aren't sure that fix is a realistic one. 'Because the behaviors are intrinsically motivating for sadists, comment moderators will likely have a difficult time curbing trolling with punishments (e.g., banning users),' says Buckels. 'Ultimately, the allure of trolling may be too strong for sadists, who presumably have limited opportunities to express their sadistic interests in a socially-desirable manner.' Perhaps posting rights should only be unlocked if you pass a test."Read Replies (0)

An anonymous reader sends this NASA report: "One year ago, on Feb. 15, 2013, the world was witness to the dangers presented by near-Earth Objects (NEOs) when a relatively small asteroid entered Earth's atmosphere, exploding over Chelyabinsk, Russia, and releasing more energy than a large atomic bomb. ... NASA is now pursuing new partnerships and collaborations in an Asteroid Grand Challenge to accelerate NASA's existing planetary defense work, which will help find all asteroid threats to human population and know what to do about them. In parallel, NASA is developing an Asteroid Redirect Mission (ARM) — a first-ever mission to identify, capture and redirect an asteroid to a safe orbit of Earth's moon for future exploration by astronauts in the 2020s. ... NASA is assessing two concepts to robotically capture and redirect an asteroid mass into a stable orbit around the moon. In the first proposed concept, NASA would capture and redirect an entire very small asteroid. In the alternative concept, NASA would retrieve a large, boulder-like mass from a larger asteroid and return it to this same lunar orbit. In both cases, astronauts aboard an Orion spacecraft would then study the redirected asteroid mass in the vicinity of the moon and bring back samples."Read Replies (0)

An anonymous reader writes "Brian Krebs has a followup to this week's 400 Gbps DDoS attack using NTP amplification. Krebs, as a computer security writer, has often been the target of DDoS attacks. He was also hit by a 200Gbps attack this week (apparently, from a 15-year-old in Illinois). That kind of volume would have been record-breaking only a couple of years ago, but now it's just normal. Arbor Networks says we've entered the 'hockey stick' era of DDoS attacks, as a graph of attack volume spikes sharply over the past year. CloudFlare's CEO wrote, 'Monday's DDoS proved these attacks aren't just theoretical. To generate approximately 400Gbps of traffic, the attacker used 4,529 NTP servers running on 1,298 different networks. On average, each of these servers sent 87Mbps of traffic to the intended victim on CloudFlare's network. Remarkably, it is possible that the attacker used only a single server running on a network that allowed source IP address spoofing to initiate the requests. An attacker with a 1 Gbps connection can theoretically generate more than 200Gbps of DDoS traffic.' In a statement to Krebs, he added, 'We have an attack of over 100 Gbps almost every hour of every day.'"Read Replies (1)
Google's Definition of 'Open'

An anonymous reader writes "One of Android's biggest draws is its roots in open source. It enables a broad range of device manufacturers to work from the same code base, and provides app developers with more insight into the platform they're building on. But openness isn't a binary condition — there are many shades of gray. While Android is technically very open, from a practical standpoint it's much more difficult for device makers to distance themselves from Google, if that's their preference. 'Phone manufacturers and carriers that want to use Google's services must conform to Google's device standards, a stricter requirement than what basic AOSP requires. For some, this is a catch. For others, it's merely the cost of doing business. ... [Dianne Hackborn, one of Android's tech leads,] defends Google's right to include proprietary services, and to keep them proprietary, saying that its no different than any other proprietary app on Android. That's not entirely true, since Google does keep some API development to itself, but to its credit the company does open-source most of the new APIs introduced to Android.'"Read Replies (0)

The Associated Press (as carried by the Washington Post) reports that the mysterious "jelly doughnut" shaped rock
spotted by the Opportunity rover on Mars wasn't put there by aliens or by mysterious forces of Mars weather. Instead, the NASA has a simple explanation: one of the rover's larger wheels "broke it off a larger rock and then kicked it into the field of view.
" Of course, they would say that just to head off a lawsuit demanding an investigation
into the real
reasons.Read Replies (1)
