Pluto Might Be Bigger Than Eris 257

astroengine writes "Look out, the battle of the dwarf planets is about to re-ignite! During last weekend's rare occultation of a star by Eris, astronomers managed to gain one of the most accurate measurements of Eris' physical size. When three Chilean telescopes watched the star blink out of sight, astronomers were shocked to find that Eris is actually a lot smaller than originally thought. So small that it might be smaller than Pluto. On speaking with Discovery News, Eris' discoverer Mike Brown said, 'While everyone is more interested in the "mine is bigger than yours" aspect, the real science is the shockingly large density of Eris.' The mass of Eris is well known, so this means the object is more dense than Pluto. Does this mean the two mini-worlds have different compositions? Did they evolve differently? In light of this finding, is the underlying argument for Pluto being demoted from the planetary club on wobbly ground?"

Submission + - When DLC Goes Wrong (goozernation.com)

kube00 writes: Poorly done DLC is one of gamers' worst nightmares right now. Where a publisher stands to make some money. Gamers get screwed, whether its the overpriced extra maps/costumes dlc, on-the-disc dlc, or DLC that is nothing more then a remake of other DLC. No game is safe from bad DLC, including Modern Warfare 2, Bioshock 2, Uncharted 2 and a host of many other popular games. Is there a chance to save DLC?

Submission + - Monetizing Free to Play Gaming Models (edery.org)

eldavojohn writes: Last week, a game consultant named David J Edery gave his two cents on why free to play (F2P) game models aren't as prolific in the West as they seem to be in the East. Aside from a few unprovable cultural divides, he makes some interesting claims concerning conversion rates of non-paying players to paying players. He outlines nuances like some customers paying hundreds for functional items and only a dollar on aesthetic items while other users might be the complete opposite. He also notes that converting a non-paying newbie into a paying customer is not the same as converting a non-paying salty dog. He defines 'aggressive monetization' to mean how much money will advance you 'unfairly' in the game. He focuses on two classes of items: those that provide performance-neutral aesthetics and those that provide performance enhancing or functional advancements. He claims to have access to ARPPU ('average revenue per paying user' per month) rates among several game developers and states that "more aggressive monetization model and a loyal, niche userbase can hope to generate $50 per paying user per month, on average" while "a F2P game that limits itself to flat subscription revenue and/or non-functional items is generally more likely to fall somewhere between $5 and $10 per paying user per month." Like any good consultant, he also gives ethics a footnote in an otherwise verbose post on monetizing free to play games. Has anyone here had experience pricing items and content in free to play games?

Submission + - How do you organize your experimental data?

digitalderbs writes: As a researcher in the physical sciences, I have generated thousands of experimental datasets that need to be sorted and organized--a problem which many of you have had to deal with as well, no doubt. I've sorted my data with an elaborate system of directories and symbolic links to directories that sort my data by sample, pH, experimental type, and other qualifiers, but I've found that through the years, I've needed to move, rename, and reorganize these directories and links, which have left me with thousands of dangling links and a heterogeneous naming scheme. What have you done to organize, tag and add metadata to your data, and how have you dealt with redirecting thousands of symbolic links at a time?

Submission + - The Hidden Security Risk of Geotags (nytimes.com)

pickens writes: The NY Times reports that security experts and privacy advocates have begun warning consumers about the potential dangers of geotags, which are embedded in photos and videos taken with GPS-equipped smartphones and digital cameras. By looking at geotags of uploaded photos "you can easily find out where people live, what kind of things they have in their house and also when they are going to be away," says one security expert. Because the location data is not visible to the casual viewer, the concern is that many people may not realize it is there; and they could be compromising their privacy, if not their safety, when they post geotagged media online. "I'd say very few people know about geotag capabilities,” says Peter Eckersley, a staff technologist with the Electronic Frontier Foundation in San Francisco, “and consent is sort of a slippery slope when the only way you can turn off the function on your smartphone is through an invisible menu that no one really knows about.”

Submission + - China to Close 2,000 Factories in Energy Crackdown (nytimes.com)

Hugh Pickens writes: "The NY Times reports that China's Ministry of Industry and Information Technology has published a list of 2,087 steel mills, cement works and other energy-intensive factories required to close by September 30 after discussions with provincial and municipal officials to identify industrial operations with outdated, inefficient technology. The goal of the factory closings is “to enhance the structure of production, heighten the standard of technical capability and international competitiveness and realize a transformation of industry from being big to being strong,” the ministry says. The current Chinese five-year plan calls for using 20 percent less energy this year for each unit of economic output than in 2005 but surging production by heavy industry since last winter has put in question China’s ability to meet this target. In addition to the energy-efficiency objective in the current five-year plan, a plan announced by President Hu Jintao late last year called for China to reduce its carbon emissions per unit of economic output by 40 to 45 percent by 2020, compared with 2005 levels."

Submission + - The shoddy state of automative security (goodgearguide.com.au) 1

angry tapir writes: "Researchers from Rutgers University and University of South Carolina have found that wireless communications between new cars and their tires can be intercepted or even forged. While the potential for misuse may be minimal, this vulnerability points to a troubling lack of rigor with secure software development for new automobiles, said Wenyuan Xu, a computer science assistant professor at the University of South Carolina, who was a co-lead on the study. The researchers will present their findings at the Usenix Security Symposium, being held this week in Washington D.C."
