Linux 3.9 brings SSD caching and drivers to support modern PCs

mtellin Linux creator Linus Torvalds last night announced the release of version 3.9 of the kernel. Available for download at kernel.org , Linux 3.9 brings a long list of improvements to storage, networking, file systems, drivers, virtualization, and power management. H-Online editor Thorsten Leemhuis has an excellent rundown of what’s new in Linux 3.9 . One new feature, listed as “experimental,” allows SSDs to act as caches for other storage devices. “This feature is able to speed up data writes, as it allows the faster SSD to first cache data and then, in a quiet moment, transfer it to the slower hard drive,” Leemhuis wrote. Linux maintainers have also done some driver work that might improve the sometimes questionable support for desktops and laptops. New drivers include support for Intel 802.11ac Wi-Fi components, as well as trackpads used in Samsung’s ARM-based Chromebook and the Dell XPS 13 Developer Edition Ultrabook . The Kernel’s driver for AMD Radeon graphics chips was updated to support Oland chips in the 8500 and 8600 Series Radeon video cards, in addition to AMD’s forthcoming Richland chips. The driver code for HD audio codecs is also now “leaner and more robust.” Read 3 remaining paragraphs | Comments

Opera claims former employee gave stolen trade secrets to Mozilla

Opera has been busy repositioning itself as a middleware player for the mobile Web recently, but that isn’t stopping the company from defending its investment in browser technology. The company has filed a 20 million Kronor ($3.4 million) lawsuit against a former employee and consultant, claiming that he stole company secrets and incorporated them into a mobile browser for Mozilla. According to a report by Norwegian IT site Digi.no , Opera has filed suit against Trond Werner Hansen, a Norwegian musician and designer who worked for Opera from 1999 to 2006 as a user interface designer and developer before  leaving to pursue his music career . Hansen also worked for Opera as an outside consultant from 2009 to 2010. Last year, Hansen was involved with the development of the Mozilla prototype “Junior” browser for Apple iOS . Hansen and Alex Limi —former Firefox UI head and now manager of Mozilla’s product design strategy—demonstrated the browser prototype in a video on Air Mozilla last June. Hansen said in the video, “I spent almost seven years trying to simplify Opera and didn’t really succeed. Simplification of something that already exists is really hard. That’s way beyond product design issues—it’s company issues. I feel like we failed in making something really easy.” Limi credited Hansen with the invention of a number of Mozilla UI features, including the browser search—”the source of all our revenue,” Limi said—and the “speed dial” feature that allows users to pick frequently visited pages from a new browser tab. “Pretty much everything he’s invented, they’re now in all browsers,” Limi continued.

Ubuntu 13.04 boosts graphics performance to prepare for phones, tablets

Ubuntu 13.04. The stable release of Ubuntu 13.04 became available for download today, with Canonical promising performance and graphical improvements to help prepare the operating system for convergence across PCs, phones, and tablets. “Performance on lightweight systems was a core focus for this cycle, as a prelude to Ubuntu’s release on a range of mobile form factors,” Canonical said in an announcement today. “As a result 13.04 delivers significantly faster response times in casual use, and a reduced memory footprint that benefits all users.” Named “Raring Ringtail,”—the prelude to Saucy Salamander —Ubuntu 13.04 is the midway point in the OS’ two-year development cycle. Ubuntu 12.04, the more stable, Long Term Support edition that is supported for five years, was released one year ago. Security updates are only promised for 9 months for interim releases like 13.04. Support windows for interim releases were recently cut from 18 months to 9 months to reduce the number of versions Ubuntu developers must support and let them focus on bigger and better things.

FBI denied permission to spy on hacker through his webcam

Sorry FBI, you can’t randomly hijack someone’s webcam. Stefano Maffei A federal magistrate judge has denied (PDF) a request from the FBI to install sophisticated surveillance software to track someone suspected of attempting to conduct a “sizeable wire transfer from [John Doe’s] local bank [in Texas] to a foreign bank account.” Back in March 2013, the FBI asked the judge to grant a month-long “ Rule 41 search and seizure warrant ” of a suspect’s computer “at premises unknown” as a way to find out more about this possible violations of “federal bank fraud, identity theft and computer security laws.” In an unusually-public order published this week , Judge Stephen Smith slapped down the FBI on the grounds that the warrant request was overbroad and too invasive. In it, he gives a unique insight as to the government’s capabilities for sophisticated digital surveillance on potential targets. According to the judge’s description of the spyware, it sounds very similar to the RAT software that many miscreants use to spy on other Internet users without their knowledge. (Ars editor Nate Anderson detailed the practice last month.) Read 10 remaining paragraphs | Comments

BitTorrent Sync creates private, peer-to-peer Dropbox, no cloud required

BitTorrent today released folder syncing software that replicates files across multiple computers using the same peer-to-peer file sharing technology that powers BitTorrent clients. The free BitTorrent Sync application is labeled as being in the alpha stage, so it’s not necessarily ready for prime-time, but it is publicly available for download and working as advertised on my home network. BitTorrent, Inc. (yes, there is a legitimate company behind BitTorrent ) took to its blog to announce  the move from a pre-alpha, private program to the publicly available alpha. Additions since the private alpha include one-way synchronization, one-time secrets for sharing files with a friend or colleague, and the ability to exclude specific files and directories.

IBM’s solar tech is 80% efficient thanks to supercomputer know-how

IBM Research’s prototype HCPVT system in Zurich. By borrowing cooling systems used in its supercomputers, IBM Research claims it can dramatically increase the overall efficiency of concentrated photovoltaic solar power from 30 to 80 percent. Like other concentrated photovoltaic (CPV) collectors, IBM’s system at its Zurich laboratory uses a mirrored parabolic dish to concentrate incoming solar radiation onto PV cells. The dish uses a tracking system to move with the sun, concentrating the collected radiation by a factor of 2,000 onto a sensor containing triple-junction PV cells. During daylight hours, each 1-sq cm PV chip generates on average between 200 and 250 watts of electrical power, harnessing up to 30 percent of the incoming solar energy. Ordinarily, the remaining 70 percent of energy would be lost as heat. But by capturing most of that heat with water, IBM Research says it is able to reduce system heat losses to around 20 percent of the total incoming energy. This results in a bottom-line efficiency of 80 percent for its CPV collector, dubbed HCPVT for High Concentration Photovoltaic Thermal. Unlike a regular CPV system, HCPVT delivers its energy in two forms: electricity and hot water. Read 7 remaining paragraphs | Comments

How “Kessler’s Flying Circus” cookie-stuffed its way to $5.2M from eBay

Wikimedia Commons Between May 2006 and June 2007, Brian Andrew Dunning made $5.2 million— all of it from eBay. Dunning wasn’t selling Velvet Elvis posters and antique dinner plates through the auction site, however. He earned the money from affiliate commissions, getting paid whenever he directed people to eBay and they made purchases or won auctions. He was so successful at driving this traffic to eBay that his company, Kessler’s Flying Circus, became the number two eBay affiliate in the entire world. His numbers grew so high and so fast that eBay began asking awkward questions almost immediately. How exactly, eBay wanted to know, was Dunning driving all of this traffic to the site? The company was well aware of the wide variety of tricks that affiliates could use to boost their stats, including one called “cookie stuffing.” With cookie stuffing, affiliates would surreptitiously “stuff” their own eBay cookie into user computers. The next time the user visited eBay, the cookie would credit any sales commissions to the affiliate’s account. (Each cookie contained an affiliate ID number; if a computer already had an eBay cookie on it, the most recently created one was used to pay out affiliate commissions.) These commissions weren’t measured in pennies, either. At the time, eBay was offering $25 to affiliates for every single new “active user” and a whopping 50 percent commission on any user’s auction wins so long as they exceeded $100 within a week’s time. eBay worried that Kessler’s Flying Circus had cookie-stuffed its way into the second place affiliate slot. But Dunning told an eBay employee looking into the matter that he was “absolutely confident” that he was operating “in line with the intended spirit of the terms.” Dunning’s partner told eBay separately that any problems were simply “coding errors.” Read 10 remaining paragraphs | Comments

Google to acquire Provo, Utah’s fiber, transform it into Google Fiber

Less than 10 days after announcing that Austin will be Google Fiber’s second city (Kansas City, KS and MO, and surrounding small towns  qualified as Google’s first), the company announced suddenly that Provo, Utah will become the “third Google Fiber City.” Interestingly, Google isn’t laying its own fiber this time, but rather purchasing an existing network. “In order to bring Fiber to Provo, we’ve signed an agreement to purchase iProvo, an existing fiber-optic network owned by the city,” the company wrote in a blog post . “As a part of the acquisition, we would commit to upgrade the network to gigabit technology and finish network construction so that every home along the existing iProvo network would have the opportunity to connect to Google Fiber. Our agreement with Provo isn’t approved yet—it’s pending a vote by the City Council scheduled for next Tuesday, April 23. We intend to begin the network upgrades as soon as the closing conditions are satisfied and the deal is closed.” Read 2 remaining paragraphs | Comments

New anti-speech low: buyer sued over negative eBay feedback

Ratings are important on eBay. Lots of buyers use them to assess the quality and reliability of particular sellers, and lots of sellers will go to great lengths to keep perfect or near-perfect ratings. But an Ohio company named Med Express has shown it’s willing to go further than other sellers: it’s willing to litigate. When Med Express got its first piece of negative feedback, it filed a lawsuit , insisting that the feedback be removed from eBay. Amy Nicholls paid $175 for a microscope light, as well as $12 for shipping. She was annoyed when she had to pay an extra $1.44 in postage due and left feedback complaining about that inconvenience. Med Express asked her to remove the feedback and she refused. The company complained that because it offered to refund her the $1.44, she should have taken down the feedback, which had the potential to hurt its business. (In the past six months, Med Express has 142 pieces of positive feedback and only one negative review.) Read 3 remaining paragraphs | Comments
