The Tech Building Blocks of City 2.0 70

CWmike writes "Sci-Fi writers call it Utopia, the glorious City of the Future. But short of downtown atriums being guarded by invisible walls and flying cars, City 2.0 is not as far off as you may think, writes John Brandon. Ubiquitous wireless networks are already available in Baltimore and Minneapolis, Thomson Reuters has sustainable data centers that sell power back to the local utility, the smart energy grid is well on its way, and city-provided social networks are common. While the concept of City 2.0 is monumental, these key technology advancements are already helping pave the road to the next-generation city. The next steps toward the city of tomorrow are all about integrating these services cohesively, making them widely available across the entire metropolis and managing the services more efficiently. 'The reality is that the city of the future will likely have many aspects of a contained and managed ecosystem,' says analyst Rob Enderle."

Dormitory Turned Into Huge Color Display Screenshot-sm 69

macson_g writes "Students from Wroclaw University of Technology (Poland) once again turned one of their dormitories into huge display. The project is called P.I.W.O. (B.E.E.R.). This time they converted a 10-story building into 4-color, 12x10 display. The business was used to display animations, and to play interactive games as well. On the project page (in Polish, Google translation here) you can watch an almost hour-long video, featuring music videos, a Tetris session, a dancing Michael Jackson, Duke Nukem and Mario."

How Google's High Speed Book Scanner De-Warps Pages 209

Hugh Pickens writes "Patent 7,508,978, awarded to Google, shows how the company has already managed to scan more than 7 million books. Google's system uses two cameras and infrared light to automatically correct for the curvature of pages in a book. By constructing a 3D model of each page and then 'de-warping' it afterward, Google can present flat-looking pages online without having to slice books up or mash them onto a flatbed scanner. Stephen Shankland writes that the 'sophistication of the technology illustrates that would-be competitors who want to feature their own digitized libraries won't have a trivial time catching up to Google.' First, a book is placed on a flat surface, while above it, an infrared projector displays a special mazelike pattern onto the pages. Next, two infrared cameras photograph the infrared pattern from different perspectives. 'The images can be stereoscopically combined, using known stereoscopic techniques, to obtain a three-dimensional mapping of the pattern,' according to the patent. 'The pattern falls on the surface of (the) book, causing the three-dimensional mapping of the pattern to correspond to the three-dimensional surface of the page of the book.'"

FCC's Duplicity On BPL Revealed 97

eldavojohn writes "Ars has a summary of the curious events surrounding the death of broadband over power lines (BPL). We've discussed BPL's trials and advances here many times. The Federal Communications Commission's go-ahead was halted last year by a federal court, after a suit by the American Radio Relay League over claims of unacceptable radio interference from BPL. The DC Court of Appeals judge noted, 'There is little doubt that the [FCC] deliberately attempted to exclude from the record evidence adverse to its position.' The ARRL's FOIA request to obtain non-redacted documents finally bore fruit under the Obama administrations more open FOIA guidelines. The ARRL's preliminary analysis of the released documents point out a few critical areas where the FCC redacted data that is clearly adverse to the claims of BPL proponents. By rights, this ought to lay BPL to rest once and for all." A story at Broadband Reports notes that BPL is dying on its own, as most of the vendors who had been testing it "have since moved on to promote smart electrical grid functionality."

Does Dell Know What Women Want In a Laptop? 669

Hugh Pickens writes "Finding the right approach for gender-specific marketing can be really tricky, said Andrea Learned, a marketing expert and author of Don't Think Pink — What Really Makes Women Buy. So when Dell recently took the wraps off a new Web site called Della, geared toward women, featuring tech 'tips' that recommended calorie counting, finding recipes, and watching cooking videos as ways for women to get the most from a laptop, a backlash erupted online, as both women and men described the Web site as 'ridiculous' and 'gimmicky.' Della's heavy emphasis on colors, computer accessories, dieting tips, and even the inclusion of a video about vintage shopping 'seems condescending to women consumers,' says Learned. Instead, Dell should have emphasized function and figured out ways to sell the netbooks that weren't clichéd and reliant on gender stereotypes. 'Some brands go too far with the girlie stuff,' Learned says. 'Della's marketing strategy sounds like it's advertising a purse. There's a level of consumer sophistication they're missing.'"

New York Times Wipes Journalist's Online Corpus 94

thefickler writes "Reading about Peter Wayner and his problems with book piracy reminded me of another writer, Thomas Crampton, who has the opposite problem — a lot of his work has been wiped from the Internet. Thomas Crampton has worked for the New York Times (NYT) and the International Herald Tribune (IHT) for about a decade, but when the websites of the two newspapers were merged two months ago, a lot of Crampton's work disappeared into the ether. Links to the old stories are simply hitting generic pages. Crampton wrote a letter to Arthur Sulzberger, the publisher of the NYT, pleading for his work to be put back online. The hilarious part: according to one analysis, the NYT is throwing away at least $100,000 for every month that the links remain broken."

Hacker Destroys Avsim.com, Along With Its Backups 780

el americano writes "Flight Simulator community website Avsim has experienced a total data loss after both of their online servers were hacked. The site's founder, Tom Allensworth, explained why 13 years of community developed terrains, skins, and mods will not be restored from backups: 'Some have asked whether or not we had back ups. Yes, we dutifully backed up our servers every day. Unfortunately, we backed up the servers between our two servers. The hacker took out both servers, destroying our ability to use one or the other back up to remedy the situation.'"

Surveying the World of the Biggest Server Farms 106

1sockchuck writes "Rackspace said this week that it is managing more than 50,000 web servers, raising the question: who else has that many? Of companies that publicly discuss their server counts, there are only a handful that are near or above the 50,000 server mark, including 1&1 Internet, The Planet, and Akamai, as well as Rackspace. The larger totals are found among companies that don't discuss how many servers they're running. The leading suspects: Google, Microsoft, Amazon and eBay."

Phoenix BIOSOS? 394

jhfry writes "In an interesting development by an unexpected source, Phoenix Technologies is releasing a Linux-based, virtualization-enabled, BIOS-based OS for computers. They implemented a full Linux distro right on the BIOS chips, and by using integrated virtualization technology, it 'allows PCs and laptops to hot-switch between the main operating system, such as Windows, and the HyperSpace environment.' So, essentially, they are 'trying to create a new market using the ideas of a fast-booting, safe platform that people can work in, but remain outside of Windows.'"

Flash Drive Roundup 311

Braedley writes "When [Ars] last took an in-depth look at USB flash drives in 2005, the landscape was a bit different. A 2GB drive ran nearly $200, and speeds were quite a bit slower then. At the time, we noted that while the then-current crop of drives was pretty fast, they still were not close to saturating the bandwidth of USB2. To top it off, a good drive was still going to set you back $50 or $70--not exactly a cheap proposition. Since our first roundup, this picture has changed considerably, and it leads to a question: has the flash drive become an undifferentiated commodity, just like any other cheap plastic tsotschke that you might find at an office supply store checkout counter?"

Dean Kamen Awarded Patent For Robot Competition Rules 110

An anonymous reader writes "Dean Kamen, the inventor of the Segway and the founder of the FIRST Robotics Competition has been granted Patent 7,507,169, that describes one of the previous competitions. The main invention is a ranking system that ranks teams not only on their score, but their opponents' score, so teams are rewarded for helping their opponents score more. It is claimed that this ranking system promotes the made up phrases 'coopertition' and 'gracious professionalism.' It had three rejections, and even more appeals, before finally being accepted six years after the first application. While a majority of his 130 patents are for things related to his inventions, which are as diverse as medical equipment, unique uses for Stirling engines, and transportation, this one seems a little dubious. Dean opposes the Patent Reform Act of 2009, which would make it easier to overturn patents after they are granted."

'Robot-loving Japanese are tinkering with screwdrivers and motors instead of heading to the beach,' and this article identifies the stores and sites serving robot hobbyists. Several sites are actually selling leftover industrial robots, but there's a variety of smaller-size robot vendors, from Tokyo's Vstone Robot Center to Carl's Electronics in Oakland (which sells sound-activated 'Hydradzoids' and solar-powered robots that crawl). Hasbro even sells their own functioning R2-D2 droid with real sonar navigation and a 'voice recognition response module.'"

Microsoft Working On Motion-Sensing Camera For the Xbox 360 68

The Wall Street Journal reports on the motion-capture technology Microsoft is rumored to be working on for the Xbox 360. "Unlike the Wii, the Microsoft camera won't require users to hold any hardware to control on-screen action, the people familiar with the matter said. The camera would sit near the television and capture when players move their hands, legs or head." The Guardian Games Blog points out that we've gotten a look at this technology before, from a company called 3DV, which was reported to be talking with Microsoft earlier this year. Many expect the specifics of this technology to be revealed at E3 early next month.

McDonalds Free Wi-Fi Users Soak Up Seating Screenshot-sm 500

bfire writes "McDonalds has earmarked potential changes to seating plans in some restaurants to prevent free Wi-Fi users from monopolizing seating, particularly in peak periods. The availability of Wi-Fi means people are now spending 35 minutes in McDonalds — rather than the average ten minutes that patrons used to spend eating there. But it appears not everyone is happy with the increased 'stickiness' of customers, with some licensees in Australia reporting that Wi-Fi users aren't turning over seats fast enough. The restaurant chain is considering options including space demarcation to deal with the problem."

Funding For Automotive Fuel Cells Cut 293

rgarbacz writes "The US will stop funding research on automotive fuel cells and redirect the work towards stationary plants, because of slow progress on the research. Developing those cells and coming up with a way to transport the hydrogen is a big challenge, Energy Secretary Steven Chu said in releasing energy-related details of the administration's budget for the year beginning Oct. 1. Dr. Chu said the government preferred to focus on projects that would bear fruit more quickly. The industry and the National Hydrogen Association criticized the decision and declared their intention to fight for funding. Dr. Chu also announced that funding for a coal gasification pilot project, cut by the Bush administration, will be reinstated. The Obama administration will also drop spending for research on the exploration of oil and gas deposits because the industry itself has ample resources for that, Dr. Chu said."

Ultra-Dense Deuterium Produced 355

Omomyid was among several readers writing in about the production of microscopic amounts of ultra-dense deuterium by scientists at the University of Gothenberg, in Sweden. A cubic centimeter of the stuff would weigh 287 lbs. (130 kg). UDD is 100,000 times more dense than water, and a million times more dense than deuterium ice, which is a common fuel in laser-ignited fusion projects. The researchers say that, if (big if) the material can be produced in large quantities, it would vastly improve the chances of starting a fusion reaction, as the atoms are much closer together. Such a D-D fusion reaction would be cleaner than one involving highly radioactive tritium. Many outlets have picked up the same press release that Science Daily printed pretty much verbatim (as is their wont); there doesn't seem to be much else about this on the Web. Here's the home page of one of the researchers. The press release gives no hint as to how the UDD was produced. Reader wisebabo asks: "I can easily imagine a material being compressed by some heavy duty diamond anvil to reach this density, the question is: what happens when you let the pressure off? Will it expand (explosively one would presume) back to its original volume?"

220-mph Solar-Powered Train Proposed In Arizona 416

Mike writes "An ambitious Arizona company has recently revealed plans for a solar powered bullet train that will streak across the desert at 220 mph, traveling from Tuscon to Phoenix in 30 minutes flat. Proposed by Solar Bullet LLC, the system comprises a series of tracks that would serve stations including Chandler, Casa Grande, Red Rock, and Marana, and may one day be extended to Flagstaff and Nogales. The train would require 110 megawatts of electricity, which would be generated by solar panels mounted above the tracks." Local coverage of the plan takes a harder look, noting that Solar Bullet LLC is two guys who are now asking local governments in the towns at which such a train would potentially stop for $35K for a legal and feasibility study. Total cost is estimated at $27B.
