Researcher Warns of "Digital Dark Age" 367

alphadogg writes "A assistant professor from the University of Illinois at Urbana-Champaign is sounding a warning that companies, the government and researchers need to come up with a plan for preserving our increasingly digitized data in light of shifting document management and other software platforms (think WordPerfect and floppy disks). Jerome P. McDonough, who teaches at the Graduate School of Library and Information Science at the University of Illinois at Urbana-Champaign, says there exists about 369 exabytes worth of data, and that includes some pretty hard to replace stuff, including tax files, email and photos. Open standards could play a key role in any preservation effort, he says. 'If we can't keep today's information alive for future generations, we will lose a lot of our culture,' McDonough said. Even over the course of 10 years, you can have a rapid enough evolution in the ways people store digital information and the programs they use to access it that file formats can fall out of date.'"

London Is Still World's Wi-Fi Access Point Capital 88

ISP Review UK writes "The latest annual Wireless Security Survey from RSA has revealed that London is still the world's wireless network (Wi-Fi) capital, with a total of 12,276 access points detected, exceeding the number found in New York City by more than 3,000. However, the French capital of Paris broke all the records with a 543% year-over-year increase in the number of wireless access points, which compares with London's 72% (down from 160% last year) and New York City's 45% (down from 49%). The survey also examined how many of the wireless access points detected were secured with some form of encryption (hotspots excluded). In New York City, 97% of corporate access points had encryption in place (76% last year). In Paris, 94% of corporate access points were encrypted — although in London, 20% of all business access points continue to be completely unprotected."

US District Court Says Calculating a Hash Value = Search 623

bfwebster writes "Orin Kerr over at The Volokh Conspiracy (a great legal blog, BTW) reports on a US District Court ruling issued just last week which finds that doing hash calculations on a hard drive is a form of search and thus subject to 4th Amendment limitations. In this particular case, the US District Court suppressed evidence of child pornography on a hard drive because proper warrants were not obtained before imaging the hard drive and calculating MD5 hash values for the individual files on the drive, some of which ended up matching known MD5 hash values for known child pornography image and video files. More details at Kerr's posting." Update: 10/28 16:23 GMT by T : Headline updated to reflect that this is a Federal District Court located in Pennsylvania, rather than a court of the Commonwealth itself.

Samsung's New Carbon Nanotube Color E-Paper 87

Iddo Genuth writes to tell us that Samsung and Unidym have shown the world's first carbon nanotube-based color e-paper. Interestingly, the new film is electrically conductive while remaining almost completely translucent and only 50 nanometers thick. "The company also mentions that the EPD [electrophoretic displays] has important advantages over conventional flat panel displays. EPDs have very low power consumption and bright light readability, which means that even under bright lights or sunlight, the user would be able to view the display clearly. Furthermore, since the device uses the thin CNT films, applications can include e-paper and displays with thin, flexible substrates. Power consumption is lowered due to the EPD's ability to reflect light and therefore able to preserve text or images on the display without frequently refreshing."

World First Review of Dell's 12.1in Netbook 133

An anonymous reader points to what's claimed to be "the world's first look at Dell's 12.1" netbook," running at Australian Personal Computer Magazine. There's a bit of gushing at the beginning, but this is followed by some informative pictures, informal battery-life tests, and interesting background about the machine's components. Upshot: it's a well-made, decent-performing small laptop with a better keyboard than smaller netbooks and more wireless options than most. However, it's shorter on battery life (bigger screen, smaller battery) than Dell's smaller Mini 9, and less easily upgraded.

100x Denser Chips Possible With Plasmonic Nanolithography 117

Roland Piquepaille writes "According to the semiconductor industry, maskless nanolithography is a flexible nanofabrication technique which suffers from low throughput. But now, engineers at the University of California at Berkeley have developed a new approach that involves 'flying' an array of plasmonic lenses just 20 nanometers above a rotating surface, it is possible to increase throughput by several orders of magnitude. The 'flying head' they've created looks like the stylus on the arm of an old-fashioned LP turntable. With this technique, the researchers were able to create line patterns only 80 nanometers wide at speeds up to 12 meters per second. The lead researcher said that by using 'this plasmonic nanolithography, we will be able to make current microprocessors more than 10 times smaller, but far more powerful' and that 'it could lead to ultra-high density disks that can hold 10 to 100 times more data than today's disks.'"

Best OS For Netbooks and Underpowered Tablets? 272

vigmeister writes "I hopped on the netbook bandwagon early this year in a rather odd fashion by picking up an outdated portable tablet (Fujitsu P1510) which just about matches the latest, greatest netbooks for their performance and portability features, while nipping them by managing to give me a better battery life. I've been happy using XP Tablet on this machine until recently, when I started thinking that by optimizing the OS for targeted use, I may be able to squeeze more out of the device. So, my questions are: What OS would you recommend for a netbook/outdated laptop? Usage is typically light — web surfing (with multimedia), email, word processing, spreadsheet and reading PDFs. Also, what OS would you recommend for a ultraportable tablet? Usage is similar to a netbook; there's a little more document editing going on, and good handwriting recognition and note-taking software would be great." Read on for further details about vigmeister's question.

Modern Methods For Sharing Innovation 91

The New York Times is running a story about Johnny Chung Lee, a hardware hacker made famous for his projects which modified the Nintendo Wiimote to do things like positional head tracking and multi-touch display control. The article focuses on the suggestion that Lee's use of YouTube to demonstrate his innovations has done a better job of communicating his ideas than more traditional methods could. Quoting: "He might have published a paper that only a few dozen specialists would have read. A talk at a conference would have brought a slightly larger audience. In either case, it would have taken months for his ideas to reach others. Small wonder, then, that he maintains that posting to YouTube has been an essential part of his success as an inventor. 'Sharing an idea the right way is just as important as doing the work itself,' he says. 'If you create something but nobody knows, it's as if it never happened.'"

PC Makers Try To Pinch Seconds From Their Boot Times 399

Some computers are never turned off, or at least rarely see any state less active than "standby," but others (for power savings or other reasons) need rebooting — daily, or even more often. The New York Times is running a short article which says that it's not just a few makers like Asus who are trying to take away some of the pain of waiting for computers, especially laptops, to boot up. While it's always been a minor annoyance to wait while a computer slowly grinds itself to readiness, "the agitation seems more intense than in the pre-Internet days," and manufacturers are actively trying to cut that wait down to a more bearable length. How bearable? A "very good system is one that boots in under 15 seconds," according to a Microsoft blog cited, and an HP source names an 18-month goal of 20-30 seconds.

Security Flaw In Android Web Browser 59

r writes "The New York Times reports on a security flaw discovered in the new Android phones. The article is light on details, but it hints at a security hole in the browser, allowing for trojans to install themselves in the same security partition as the browser: 'The risk in the Google design, according to Mr. Miller, who is a principal security analyst at Independent Security Evaluators in Baltimore, lies in the danger from within the Web browser partition in the phone. It would be possible, for example, for an intruder to install software that would capture keystrokes entered by the user when surfing to other Web sites. That would make it possible to steal identity information or passwords.'"

Shuttleworth On Redefining File Systems 414

moteyalpha writes "Mark Shuttleworth described the beginnings of what could a great step forward in making file systems more usable. I've personally had the experience of trying to find a file for a customer who had just finished editing a critical report, saved it, and then couldn't locate it to deliver to their client. Quoting: 'My biggest concern on this front is that it be done in a way that every desktop environment can embrace. We need a consistent experience across GNOME, KDE, OpenOffice and Firefox so that content can flow from app to app in a seamless fashion and the user's expectations can be met no matter which app or environment they happen to use. If someone sends a file to me over Empathy, and I want to open it in Amarok, then I shouldn't have to work with two completely different mental models of content storage.'"

White Space Debate Intensifies As Vote Approaches 94

Ars Technica reports that the debate between broadcasters and white space supporters has intensified after each side recently made inflammatory comments and suggested that science would vindicate their position. Several organizations are pushing to delay the upcoming white space vote, in part because it takes place on the same day as the US presidential election. We recently discussed Google's claim that a test of this system was rigged to fail. From Ars: "The broadcasters contend that adjacent channel interference would be significant even at the 40 mW level proposed by Kevin Martin. In fact, they claim that such a device would interfere with digital television signals when the viewer is 25 miles from the television tower and the whitespace device is 10m or less from the TV set. At 50 miles from the television tower, a whitespace device within 50m from a set could allegedly cause interference. The broadcasters also want several safeguard requirements put on the technology that go beyond the new, lower-power transmission levels."

Packs of Robots Will Hunt Down Uncooperative Humans 395

Ostracus writes "The latest request from the Pentagon jars the senses. At least, it did mine. They are looking for contractors to 'develop a software/hardware suite that would enable a multi-robot team, together with a human operator, to search for and detect a non-cooperative human subject. The main research task will involve determining the movements of the robot team through the environment to maximize the opportunity to find the subject ... Typical robots for this type of activity are expected to weigh less than 100 Kg and the team would have three to five robots.'" To be fair, they plan to use the Multi-Robot Pursuit System for less nefarious-sounding purposes as well. They note that the robots would "have potential commercialization within search and rescue, fire fighting, reconnaissance, and automated biological, chemical and radiation sensing with mobile platforms."

Hubble Repairs Hindered By Antiquated Computer Systems 193

Andrew Moseman writes "Part of the trouble NASA is encountering while fixing the Hubble Space Telescope comes from the fact that it's been up there for nearly two decades, and therefore carries computer systems long outdated here on Earth. 'One of the main computers that the Goddard team has been struggling with during the repair attempts runs on an Intel 486 chip, the height of 1989 technology.' Many of NASA's long-running missions rely on antiquated systems — the Voyager probes each have about 32k of memory — but the scientists say they can manage."

Amazon Kindle Endorsed By Oprah 197

Oprah Winfrey enthused about the Amazon Kindle on her show today — it's her "new favorite thing" — and had Jeff Bezos on to announce a $50-off offer good till Nov. 1. A plug on Oprah is ordinarily a sign that a product has crossed over into the mainstream. But her show's audience has been slipping lately, and it's unclear how many cash-strapped citizens will be willing to part with $309 (after the special offer) for a new techno-gadget, for which they then have to shell out more money for DRM-encrusted content.

Storing Qubits In Nuclei 90

bednarz writes "Scientists have demonstrated what is being called the 'ultimate miniaturization of computer memory,' storing data for nearly two seconds in the nucleus of an atom of phosphorus. The hybrid quantum memory technique is a key step in the development of quantum computers, according to the National Science Foundation. An international team of scientists demonstrated that quantum information stored in a nucleus has a lifetime of about 1¾ seconds. 'This is significant because before this technique was developed, the longest researchers could preserve quantum information in silicon was a few tens of milliseconds. Other researchers studying quantum computing recently calculated that if a quantum system could store information for at least one second, error correction techniques could then protect that data for an indefinite period of time.'" Here's the NSF press release with pictures of the apparatus. They claim that this technique is promising because it "uses silicon technology" seems a bit of a stretch — the silicon the researchers employed was a painstakingly grown crystal of extremely high purity.

Nintendo Blocks Homebrew Installation 251

ElementC writes "Sometime yesterday Nintendo uploaded the latest Wii system update. This update quietly patches a few bugs that allowed the installation of both homebrew and warez apps. Currently installed apps such as the Homebrew Channel and the video DVD library, DVDX, are reportedly not affected. Those not installing this update are blocked out of the Wii Shop channel and in the future may be blocked out of certain games. Team Twiizers cracked the last update within about eight hours. They're already on the case. Readers familiar with the architecture of the Wii will find the list of currently discovered changes interesting."

Australia Developing Massive Electric Vehicle Grid 260

blairerickson writes "A US firm Thursday unveiled plans to build a massive one-billion-dollar charging network to power electric cars in Australia as it seeks cleaner and cheaper options to petrol. Better Place, which has built plug-in stations for electric vehicles in Israel and Denmark, has joined forces with Australian power company AGL and finance group Macquarie Capital to create an Australian network. Under the plan, the three cities will each have a network of between 200,000 and 250,000 charge stations by 2012 where drivers can plug in and power up their electric cars. The points would probably be at homes and businesses, car parks and shopping centres. In addition, 150 switch stations will be built in each city and on major freeways, where electric batteries can be automatically replaced in drive-in stations similar to a car wash." I hope they're talking to the car companies about the necessary standardization it would take to make this work, too.
