Dell Says 90% of Recorded Business Data Is Never Read 224

Barence writes "According to a Dell briefing given to PC Pro, 90% of company data is written once and never read again. If Dell's observation about dead weight is right, then it could easily turn out that splitting your data between live and old, fast and slow, work-in-progress versus archive, will become the dominant way to price and specify your servers and network architectures in the future. 'The only remaining question will then be: why on earth did we squander so much money by not thinking this way until now?'" As the writer points out, the "90 percent" figure is ambiguous, to put it lightly.

When Telemarketers Harass Telecoms Companies 234

farnz writes "Andrews & Arnold, a small telecoms company in the UK, have recently been hit with an outbreak of illegal junk calls. Unlike larger firms, they've come up with an innovative response — assign 4 million numbers to play recordings to the telemarketers, put them on the UK's Do-Not-Call list and see what happens. Thus far, the record is over 3 minutes before a telemarketer works out what's going on." The sound quality (and the satisfying humor) of the recording gets better as it goes on.

NASA's Plutonium Supply Dwindling; ESA To Help 173

astroengine writes "NASA's stockpile of the plutonium isotope Pu-238 is at a critical level, causing concern that there won't be enough fuel for future deep space missions. Pellets of Pu-238 are used inside radioisotope thermoelectric generators (or RTGs) to generate electricity for space probes traveling beyond the orbit of Mars — solar energy is too weak for solar arrays at these distances. Blocked by a contract dispute with Russia to supply Pu-238 and the US Department of Energy that has not been granted funds to produce more of the isotope, NASA lacks enough of the radioisotope to fuel the future joint NASA-ESA mission to Europa. However, the head of the European Space Agency has announced that they have plans to commence a new nuclear energy program to alleviate the situation."

Microsoft Applies For Page-Turn Animation Patent 293

eldavojohn writes "Ever seeking to out innovate their competition, Microsoft has applied for a patent on animating page flips in devices like the Nook or Kindle. The application summary reads, 'One or more pages are displayed on a touch display. A page-turning gesture directed to a displayed page is recognized. Responsive to such recognition, a virtual page turn is displayed on the touch display. The virtual page turn actively follows the page-turning gesture. The virtual page turn curls a lifted portion of the page to progressively reveal a back side of the page while progressively revealing a front side of a subsequent page. A lifted portion of the page is given an increased transparency that allows the back side of the page to be viewed through the front side of the page. A page-flipping gesture quickly flips two or more pages.' Maybe you've seen this before?"

Internet Censorship Arms Race Gets New Weapon From Georgia Tech 75

coondoggie writes "Trying to get out in front of what they call a censorship arms race, a team of researchers has come up with technology that lets users exchange messages through heavily censored networks in countries such as China and North Korea in hidden channels via user-generated content sites such as Twitter or Flickr. Researchers with the Georgia Tech School of Computer Science will demo the technology known as Collage for the first time at next month's Usenix security conference and ideally have a working package the public can download by the end of August."

Hack Exposes Pirate Bay User Data 156

tsu doh nimh writes "A group of hackers from Argentina recently broke into the database for thepiratebay.org, the Internet's largest torrent search engine, exposing user names, Internet addresses, and (MD5) hashed password data on more than 4 million users, according to Brian Krebs. He interviewed the leader of the group, Ch Russo, who said they briefly considered what the information would be worth to the RIAA and MPAA before going public with the breach. From the story: 'Probably these groups would be very interested in this information, but we are not [trying] to sell it,' Russo said. 'Instead we wanted to tell people that their information may not be so well protected.'"

RIAA's Tenenbaum Verdict Cut From $675k To $67.5k 253

NewYorkCountryLawyer writes "In SONY BMG Music Entertainment v. Tenenbaum, the Court has reduced the jury's award from $675,000, or $22,500 per infringed work, to $67,500, or $2,250 per infringed work, on due process grounds, holding that the jury's award was unconstitutionally excessive. In a 64-page decision (PDF), District Judge Nancy Gertner ruled that the Gore, Campbell, and Williams line of cases was applicable to determining the constitutionality of statutory damages awards, that statutory damages must bear a reasonable relationship to the actual damages, and that the usual statutory damages award in even more egregious commercial cases is from 2 to 6 times the actual damages. However, after concluding that the actual damages in this case were ~ $1 per infringed work, she entered a judgment for 2,250 times that amount. Go figure." That $2,250 per infringed work figure should look familiar from Jammie Thomas-Rassett's reduced damages judgment — $54,000 for 24 songs.

Antibody Discovered To Boost HIV Vaccines 144

An anonymous reader sends this clip from Scienceblog.com. "Scientists have discovered two potent human antibodies that can stop more than 90 percent of known global HIV strains from infecting human cells in the laboratory, and have demonstrated how one of these disease-fighting proteins accomplishes this feat. ... Research efforts to find individual antibodies that can neutralize HIV strains have been difficult because the virus continuously changes its surface proteins to evade recognition by the immune system. As a consequence of these changes, an enormous number of HIV variants exist worldwide. However, there are a few surface areas that remain nearly constant across all variants of HIV and scientists have now discovered two potent human antibodies that attach to one of these sites and can stop more than 90 percent of known global HIV strains from infecting human cells in the laboratory. ... The researchers also confirmed that VRC01 does not bind to human cells — a characteristic that might otherwise lead to its elimination during immune development, a natural mechanism the body employs to prevent autoimmune disease."

Google Street View Wi-Fi Data Includes Passwords, Email Content 292

snydeq writes "The French National Commission on Computing and Liberty has found passwords and email messages among the Street View Wi-Fi data Google intercepted, InfoWorld reports. The data protection authority has been investigating Google's recording of traffic carried over unencrypted Wi-Fi networks. Google has said it collected only 'fragments' of personal web traffic as it passed by because its Wi-Fi equipment automatically changes channels five times a second. With Wi-Fi networks operating at up to 54Mbps, however, those 'fragments' may have been more than that. 'We can already state that [...] Google did indeed record email access passwords [and] extracts of the content of email messages,' CNIL said."

80-Year-Old Edison Recording Resurrected 133

embolalia writes "An 80-year-old recording of a live radio broadcast featuring Thomas Edison has been uncovered and reconstituted. The recording was done on an obscure technology called a pallophotophone — Greek for 'shaking light sound' — that uses optical film to reproduce sound. The archivists who uncovered the canisters tucked away on a bottom shelf in a museum in Schenectady, New York (the city where Edison's General Electric was founded), did not have any machine to replay the films. Two GE engineers — working nights and weekends for two years — were able to construct a machine to replay the old tapes, recorded only two years before Edison's death." There's a video at the link, which may or may not contain some of the resurrected recording, but we couldn't get it to play from the Times Union site.

Sleeping iPhones Send Phantom Data 248

Stoobalou writes with a story that got started earlier this month when iPhone users in the US and the UK noticed that their phones seemed to be sending large data bursts via 3G overnight. (Providers are ending unlimited contracts, so iPhone users are paying more attention to how much data they are using.) The discussions began on MacOSRumors and an Apple discussion forum. Thinq.co.uk makes this guess as to what is going on, but doesn't offer much in the way of substantiation: "The simple fact of the matter is — as far as we can tell — that the iPhone's push notifications and other small transfers of data are totted up throughout the day and the total for all of those notifications is added up after dark and sent to your airtime provider while your phone is sleeping. If these tiny amounts of data were individually listed your bill would probably be the size of a telephone directory. The reason it is using the 3G network rather than Wi-Fi is that all iPhones up to and including the 3Gs turn off Wi-Fi push functionality while the phone is in sleep mode, in order to preserve battery life. The iPhone 4, incidentally, has better power management so will not need to do this."

DIY Synthetic Aperture Radar 118

An anonymous reader lets us know about a DIY synthetic aperture radar built for $240 in parts (give or take). Here's PDF slideware from the Ph.D. student's research. "Using a discarded garage door opener, an old cordless drill, and a collection of surplus microwave parts, a high resolution X-band linear rail synthetic aperture radar (SAR) imaging system was developed for approximately $240 material cost. Entry into the field of radar cross section measurements or SAR algorithm development is often difficult due to the cost of high-end precision pulsed IF or other precision radar test instruments."

Quantum Dots Could Double Solar Energy Efficiency 112

dptalia notes the recent publication in Science of research demonstrating a way to use hot electrons in solar cells, resulting in an overall energy conversion efficiency of 66%. Here is the abstract in Science; access to the full article requires a subscription. "A team of University of Minnesota-led researchers has cleared a major hurdle in the drive to build solar cells with potential efficiencies up to twice as high as current levels, which rarely exceed 30 percent. ... Tisdale and his colleagues demonstrated that quantum dots — made not of silicon but of another semiconductor called lead selenide — could indeed be made to surrender their 'hot' electrons before they cooled. The electrons were pulled away by titanium dioxide, another common inexpensive and abundant semiconductor material that behaves like a wire."

Bill Proposes Canadian Cellphone Unlocking Rights 359

SJrX sends in a CBC report that the Canadian New Democratic Party has tabled a bill requiring all cellphone companies to provide unlocked cellphones. (Wikipedia notes, "The party is regarded as falling on the left in the Canadian political spectrum.") This reader adds, "The fact that there is a minority government currently should help this bill's chances of getting passed." "The bill proposes three rules: cellphone carriers would be required to notify customers at the point of purchase whether a phone is locked to work only on their network; they would have to remove such a lock free of charge at any point after the conclusion of the customer's service contract; and they would have to remove it if the customer does not enter into a contract within six months of buying the device up front."
