Dr. Hok writes "As more and more renewable energy enters the grid, it gets increasingly difficult to match supply and demand 24/7. The answer of German power company Lichtblick and Volkswagen is a swarm of 100,000 flexible base-load generators. These fridge-sized CHP (Combined Heat and Power) generators that will be installed in people's basements in Hamburg starting early next year will feed electricity into the grid and the waste heat into their home's water/heating. The "ZuhauseKraftwerk" (HomePowerPlant) features a vanilla VW Golf natural-gas engine that generates 20kW electrical and 34 kW heat with an efficiency of 92%. The units are remotely controlled via a mobile network or DSL; they can ramp up in a minute if needed. A water tank ensures that heat is continuously available, while electricity is produced on demand. The swarm will replace two nuclear plants, they say. And your old oil heating needed replacement anyway."

Al writes "Many people reveal way too much personal information on social networking sites — something that can easily lead to identity theft or unwanted attention from employers etc. Technology Review has a story about several cryptographic tools that can be used to hide your activity on Facebook, from both untrusted users and from Facebook itself. Urs Hengartner, an assistant professor of computer science at the University of Waterloo, developed a Firefox plugin that obfuscates anything marked with '@@' on Facebook and only reveals the correct information to trusted users who have the right keys. The sensitive data itself is even stored on an outside server so that even Facebook cannot access it. The piece mentions two other projects, NOYB and flybynight, that also aim to make personal information more secure on Facebook."

wonkavader writes "Tuesday was a good day for smartbook news. News articles from Sept. 8 tell us that both Foxconn and Hon Hai are developing ARM-based smartbooks. PC World reports that Foxconn's devices 'use a few different Linux operating systems, including one similar to the Intel-backed Moblin OS and one developed by Foxconn. The company is currently looking into Google's Android mobile OS for possible use as well.' Reuters reports that Hon Hai is also developing them. Hon Hai makes the iPhone and the Wii."

(Sensors on the skin detect traces of nerve signals from the brain, synchronizing the power suit's movements with the user's own limbs.) New video shows the suits in use on the streets of Tokyo, and the concept may be catching on. DARPA now has a program called Exoskeletons for Human Performance Augmentation 'to develop devices and machines that will increase the speed, strength and endurance of soldiers in combat environments.'"

ThousandStars sends us to The Wall Street Journal for a report that momentum for nuclear energy is waxing in the US. "For the first time in decades, popular opinion is on the industry's side. A majority of Americans thinks nuclear power, which emits virtually no carbon dioxide, is a safe and effective way to battle climate change, according to recent polls. At the same time, legislators are showing renewed interest in nuclear as they hunt for ways to slash greenhouse-gas emissions. The industry is seizing this chance to move out of the shadow of Three Mile Island and Chernobyl and show that it has solved the three big problems that have long dogged it: cost, safety and waste."

Ars has a review of recent research, and a summary of the history, in the field of reidentification — identifying people from anonymized data. Paul Ohm's recent paper is an elaboration of what Ohm terms a central reality of data collection: "Data can either be useful or perfectly anonymous but never both." "...in 2000, [researcher Latanya Sweeney] showed that 87 percent of all Americans could be uniquely identified using only three bits of information: ZIP code, birthdate, and sex. ... For almost every person on earth, there is at least one fact about them stored in a computer database that an adversary could use to blackmail, discriminate against, harass, or steal the identity of him or her. I mean more than mere embarrassment or inconvenience; I mean legally cognizable harm. ... Reidentification science disrupts the privacy policy landscape by undermining the faith that we have placed in anonymization."

Vigile writes "Not many people have debated that Intel's Nehalem architecture is the fastest available for consumer desktop computers since it was released last year, but quite a few have complained about the cost of the platform. Intel just released new Lynnfield-based processors under both the Core i7 and Core i5 names and tests are showing the new CPUs beating Nehalem in both performance-per-watt and performance-per-dollar tests to a startling degree. And while raw performance probably still goes to the Nehalem-based Core i7 CPUs, the lower prices of motherboards and memory for Lynnfield processors will likely more than make up for it." Update: 09/08 14:03 GMT by T : There are more eye-wateringly exhaustive examinations of the new chips all over the Web; here's HotHardware's version, and Tom's Hardware's.

Hugh Pickens writes "With the perspective of forty-plus years since my graduation, I would say the single most useful course I took in high school was a business class in touch-typing that gave me a head start for writing and with computers that I have benefited from my entire life. So it was with particular interest that I read Gordon Rayner's essay in the Telegraph proposing that schools add a mandatory course in touch typing to the cornerstones of education: reading, writing and arithmetic. 'Regardless of the career a child takes up when they leave school, a high percentage of them will use a keyboard in their daily work, and all of them are likely to use a keyboard in their leisure time,' writes Rayner. 'Touch-typing would help every child throughout their lives — so why are our schools so blind to this?'"

djk1024 writes "I've just filed for a patent on a new approach to motion capture that is simple, cheap, easy, accurate, and portable. It's RF-based, accurate to 1 mm, and simple enough that a sophisticated hobbyist could build one in a couple weekends from plans and standard electronics. So now what? I quit my job and have been working on this full-time for the past couple of years; now I'm out of money so can't continue development on my own. I'm also not an electrical or RF guy so I can't carry out my own independent development on the electronics. I'm quite frustrated at this point. I've been in the software development field for over 30 years and have gone through a large number of startups, but always just as the head techie, and always as part of a team. This doing it alone sucks. I would love some advice on how best to go forward."

innocent_white_lamb writes "The Canadian Private Copying Collective is pushing for the implementation of an iPod fee in Canada to compensate them for 'losses' when people copy music to their digital music players. They have collected a fee from every CDR sold in Canada since 1997 and now want to extend that to digital music players. From the article: 'Some have argued that once they buy a CD they shouldn't have to pay again and again to listen to those songs — which they already purchased — on a personal compilation CD or on their MP3 player. But for people like Milman and Basskin, it's about recognizing the value of those works. "There has to be some sort of way to compensate the artist for the hours and the sweat and the blood and the tears and the extreme, extreme expense that goes into making music," Milman said.'"

The Digital Foundry blog has an article about measuring an important but often nebulous aspect of console gameplay: input lag. Using a video camera and a custom input monitor made by console modder Ben Heck, and after calibrating for display lag, they tested a variety of games to an accuracy of one video frame in order to determine the latency between pressing a button and seeing its effect on the screen. Quoting: "If a proven methodology can be put into place, games reviewers can better inform their readers, but more importantly developers can benefit in helping to eliminate unwanted lag from their code. ... It's fair to say that players today have become conditioned to what the truly hardcore PC gamers would consider to be almost unacceptably high levels of latency to the point where cloud gaming services such as OnLive and Gaikai rely heavily upon it. The average videogame runs at 30fps, and appears to have an average lag in the region of 133ms. On top of that is additional delay from the display itself, bringing the overall latency to around 166ms. Assuming that the most ultra-PC gaming set-up has a latency less than one third of that, this is good news for cloud gaming in that there's a good 80ms or so window for game video to be transmitted from client to server."

angry tapir writes "The San Diego Supercomputer Center has built a high-performance computer with solid-state drives, which the center says could help solve science problems faster than systems with traditional hard drives. The flash drives will provide faster data throughput, which should help the supercomputer analyze data an 'order of magnitude faster' than hard drive-based supercomputers, according to Allan Snavely, associate director at SDSC. SDSC intends to use the HPC system — called Dash — to develop new cures for diseases and to understand the development of Earth."

The big news about game consoles of late are the recent price drops and hardware changes. However, an editorial at GamesIndustry looks into one of the side effects of those updates: decisions by both Microsoft and Sony not to include HDMI cables with their HD-capable consoles, despite the companies' long-standing interest in high-definition gaming. "From the perspectives of these companies, they want to include the cable which will be of most utility to the largest group of consumers possible, and it's clear that whatever research they have done suggests that the majority of consumers don't need — or rather, can't use — an HDMI cable. Neither firm wants to put an assortment of cables in the box 'just in case' — each additional cable erodes millions from the firm's profitability, after all. ... Supporting evidence that all is not well with the HD transition comes from Epic Games' Mark Rein, who told Eurogamer earlier this summer that 'over half the users who played Gears of War 2 so far do not have HDTVs.' Gears of War is a core gamer franchise, beloved of early adopters and the [so-called] hardcore. If less than half of those users are playing on HDTVs, what must the percentages be like for games like FIFA and Pro Evolution Soccer — let alone Singstar and Buzz, or popular movie tie-in titles?"

stoolpigeon writes "Scientists on Florida's Gulf Coast are trying to find an underwater robot that has mysteriously vanished. The robot from the Mote Marine Laboratory in Sarasota has been missing since Monday. The robot, which cost about $100,000, was equipped with a detector to find red tide, a toxic algae bloom. The detector was valued at another $30,000. Scientists aren't sure what happened to the robot, which is nicknamed Waldo."

Al writes "It might not please many environmentalists, but a major energy company is adding solar-thermal power to a coal plant and says this could be the cost-effective way to produce energy while lowering CO2 emissions. Abengoa Solar and Xcel Energy, Colorado's largest electrical utility, have begun modifying the coal plant, which is based near Grand Junction, Colorado. Under the design, parabolic troughs will be used to preheat water that will be fed into the coal plant's boilers, where coal is burned to turn the water into steam. Cost savings comes from using existing turbines and generators and from operating at higher efficiencies, since the turbines and generators in solar-thermal plants are normally optimized to run at the lower temperatures generated by parabolic mirrors."

Lucas123 writes "Intel is planning to launch its native flash memory module, code named Braidwood, in the first or second quarter of 2010. The inexpensive NAND flash will reside directly on a computer's motherboard as cache for all I/O and it will offer performance increases and other benefits similar to that of adding a solid-state disk drive to the system. A new report states that by achieving SSD performance without the high cost, Braidwood will essentially erode the SSD market, which, ironically, includes Intel's two popular SSD models. 'Intel has got a very good [SSD] product. But, they view additional layers of NAND technology in PCs as inevitable. They don't think SSDs are likely to take over 100% of the PC market, but they do think Braidwood could find itself in 100% of PCs,' the report's author said."
