Collaborative Filtering and the Rise of Ensembles 58

igrigorik writes "First the Netflix challenge was won with the help of ensemble techniques, and now the GitHub challenge is over, and more than half of the top entries are also based on ensembles. Good knowledge of statistics, psychology and algorithms is still crucial, but the ensemble technique alone has the potential to make the collaborative filtering space a lot more, well, collaborative! Here's a look at the basic theory behind ensembles, how they shaped the results of the GitHub challenge, and how this pattern can be used in the future."

Japan Plans $21B Space Power Plant 550

Mike writes "Japan has announced plans to send a $21 billion solar power generator into space that will be capable of producing one gigawatt of energy, or enough to power 294,000 homes. The project recently received support from Mitsubishi Electric Corp. and IHI Corp, who are now teaming up in the race to develop new technology within four years that can beam electricity back to Earth without the use of cables. Japan hopes to test a small solar satellite decked out with solar panels by the year 2015."

Tour Companies Battle Over Trademarked Duck Noises 251

Tour company Ride the Ducks is suing rival tour company Bay Quackers, alleging that it holds trademark rights to the sound made by tourists using duck call devices, while on amphibious vehicle tours. San Francisco-based Ride the Ducks holds a 'sound mark' on the noise. Very few companies hold sound marks, but some of the more famous include: the NBC chimes and the MGM lion. The company holds US Trademark No. 2,484,276, which protects a mark consisting of 'a quacking noise made by tour guides and tour participants by use of duck call devices throughout various portions of [guided amphibious vehicle] tours.' Reading this makes my think that there is a room full of litigious monks somewhere, just waiting for someone to try clapping with one hand.

Augmented Reality In a Contact Lens 196

Toe, The writes "Bionanotechnology researcher Babak A Parviz writes about his research toward producing a computer interface in a contact lens. At the moment, they have only embedded a single LED, but they foresee a much more complex interface such as detailed in Vernor Vinge's Rainbows End. Such lenses potentially could also read human bio-information from the eye, providing medical information on the order of what is now taken from blood tests, but on a continuous basis. An example would be monitoring glucose levels for diabetics. The author states that, 'All the basic technologies needed to build functional contact lenses are in place,' and details what refinements and advances will be necessary to bring this technology to reality."

Military To Spend $42M To Build Advanced Network Control 102

coondoggie writes "BBN, which was bought by defense giant Raytheon today, got almost $11 million to help build self-configuring network technology that would identify traffic, let the network infrastructure prioritize it down to the end user, reallocate bandwidth between users or classes of users, and automatically make quality-of-service decisions. The advanced network technology is being developed by Defense Advanced Research Projects Agency (DARPA) and will include support for features like 32 levels of network traffic prioritization that will let data with a higher priority will be handled more expeditiously than traffic with a lower priority."

IBM Patents Tweeting Remote Control 282

Fluffeh writes "IBM has applied for a patent on a network-enabled smart remote control that sends out a message to Twitter, Facebook or a blog when you start watching a TV show." Hopefully this launches an exciting patent landgrab of devices that are socially enabled. Your car can tweet when you leave your garage. Your dishwasher can tweet when the load is done. Your skillet can tweet when your eggs are burnt. And they say innovation is dead.

Sony To Put Chrome On Laptops 278

consonant writes "FT is reporting that Google has reached a deal with Sony to ship Chrome on the Vaio line of PCs. Google confirmed that Sony PCs carrying Chrome had started to go on sale and said it was in talks for similar deals with other computer makers. It said the arrangement was 'experimental' and part of wider efforts to boost distribution, including a deal to make Chrome available to internet users who download the RealPlayer software and the company's first use of television advertising. While mainstream media coverage and financial details were very sparse, El Reg terms it a 'Microsoft-snubbing deal.' Google also mentioned it was pushing for similar deals with other vendors. Could this spell the beginning of the end for IE?"

Tetris Improves Your Brain 145

An anonymous reader writes "Playing Tetris increases the density of the cortex and improves the efficiency of some parts of the brain, according to researchers investigating video games and other complex spatial tasks." Unfortunately, storing a half million copies of the song negates any practical functional gains beyond loading your trunk very efficiently.

EBay Sells Skype To Marc Andreessen 125

Julefrokost writes "Computerworld has a story about eBay selling Skype. Marc Andreessen, co-founder of Netscape, along with a group of investors, are reported to have paid $2 billion for Skype. According to the New York Times, Google was also a potential buyer. Also, the original founders of Skype are said to have placed a bid, but Marc Andreessen & Co was the highest bidder."

Swarms of Solar-Powered Microbots On the Way 119

Mike writes to tell us that Inhabitat has an interesting article, complete with some pretty pictures, about a new solar-powered swarm robot that could be used to collect data and aid in surveillance. "These mini-robots are quite revolutionary, considering that they contain all that's necessary to collect data and relay it back using one single circuit board. In the past single-chip robots have presented significant design and manufacturing challenges due in part to the use of solder as an adhesive. These new microbots use conductive adhesive to attach the components to a double-sided flexible printed circuit board using surface mount technology. The circuit is then folded into thirds and wrapped around the ASIC (application-specific integrated circuit). On top, a solar cell generates power for the robot and delivers 3.6 V to the unit, which is enough for it to walk. Locomotion is achieved via three vibrating legs, while a fourth horizontal vibrating leg is used as a touch sensor."

Drop in P2P Traffic Attributed To Traffic Shaping 251

An anonymous reader writes "A new report based on data from 100 US and European ISPs claims P2P traffic has dropped to around 20% of all Internet traffic. This is down from the 40% two years ago (also reported by the same company which sells subscriber traffic management equipment to ISPs). The report goes on to say the drop is likely due to continued, widespread ISP P2P shaping: 'In fact, the P2P daily trend is pretty much completely inverted from daily traffic. In other words, P2P reaches its low at 4pm when web and overall Internet traffic approaches its peak ... trend is highly suggestive of either persistent congestion or, more likely, evidence of widespread provider manipulation of P2P traffic rates.'"

Sony and Nintendo Step Up Anti-Piracy Efforts 147

Edge reports that Sony and Nintendo are both expanding their anti-piracy operations in an effort to reduce piracy rates on the PSP and the DS respectively. Nintendo has hired Neil Boyd, who handled anti-piracy operations for Warner Brothers, to help them demonstrate their "willingness to take action against criminals who are making money out of the infringement of games developers' copyright." Sony has taken a more direct approach, choosing to alter the hardware used in the PSP Go so that things like the Pandora battery can no longer be used to alter the firmware.

Making Babies In Space May Not Be Easy 262

Hugh Pickens writes "Studies of reproduction in space have previously been carried out with sea urchins, fish, amphibians and birds, but Brandon Keim writes in Wired that Japanese biologists have discovered that although mammalian fertilization may take place normally in space, as mouse embryos develop in microgravity their cells have trouble dividing and maturing. The researchers artificially fertilized mouse eggs with sperm that had been stored inside a three-dimensional clinostat, a machine that mimics weightlessness by rotating objects in such a way that the effects of gravity are spread in every direction. Some embryos were ultimately implanted in female mice and survived to a healthy birth, but at lower numbers than a regular-gravity control group. Part of the difference could be the result of performing tricky procedures on sensitive cells, but the researchers suspect they also reflect the effect of a low-gravity environment on cellular processes that evolved for Earth-specific physics. '"These results suggest for the first time that fertilization can occur normally under G environment in a mammal, but normal preimplantation embryo development might require 1G," concludes the report. "Sustaining life beyond Earth either on space stations or on other planets will require a clear understanding of how the space environment affects key phases of mammalian reproduction."'"

EMC Co-Founder Commits Suicide 538

The Register is reporting that EMC co-founder Richard Egan has committed suicide. The article has an interesting look back at some of his accomplishments. "Egan had an amazing life, encompassing involvement in the Apollo space program, the US Marines, starting and building the most successful storage company on the planet, and becoming the US ambassador to Ireland. Finally, aged 73 and facing a lingering death, he ended the battle decisively and on his terms. He was never a shrinking violet."
