Game Publishers Using Stealth P2P Clients

An anonymous reader writes "TorrentFreak has shed some light on the dark practice of installing stealth-mode P2P clients during game downloads and using unsuspecting gamers' PCs as 'bandwidth slaves.' The clients operate in the background and largely go unnoticed until problems arise that are caused by overactive uploading/seeding. While the Akamai NetSession Interface and Pando Media Booster are specifically called out, there appear to be other offenders as indicated in the comments left by TorrentFreak readers. A publisher called Solid State Networks is putting out a call for an industry-wide 'best practices' effort to promote transparency, control and privacy on behalf of gamers who are otherwise being abused for their bandwidth without their consent."

Winnie-the-Pooh Parodied In Wookie-the-Chew

pickens writes "Erik Hayden writes in the Atlantic that children will see endearing portraits of Chewbacca rendered in the style of "Winnie-the-Pooh" in the book of drawings "Wookie the Chew," a tribute to the combined genius of George Lucas, A.A.Milne and E.H.Sheppard, by artist James Hance released on September 1st. Samples from the book are available at Hance's web site. Hance bases his right to parody Winnie-the-Pooh on Fair Use as parody under which certain uses of copyrighted works, which would otherwise be considered infringing, are permissible. Interestingly enough, the rights to the original Winnie-the-Pooh were the subject of an 18-year feud in which Walt Disney corporation fought off a challenge to its ownership of the rights ending in 2009 when a judge in Los Angeles struck out a claim against Disney lodged by the family of Stephen Slesinger, a comic book pioneer who bought the copyright to Pooh in 1930 from the bear's British creator, A.A. Milne. Stories of Pooh's adventures were originally created by Milne in the 1920s, based on a toy bear owned by the author's son, Christopher Robin."

2010 May Be the First Year YouTube Turns a Profit

eldavojohn writes "Analysts are saying that this year will be the first year YouTube turns a profit. From the New York Times article: 'In the last year, the video site has become a significant contributor to the family business at a time when Google, which makes more than 90 percent of its revenue from text search ads, is seeking a second act. Though Google does not report YouTube's earnings, it has hinted that it is hovering near profitability. Analysts say YouTube will bring in around $450 million in revenue this year and earn a profit. Revenue at YouTube has more than doubled each year for the last three years, according to the company.' Of course a little over a year ago we were being told that YouTube was losing around $1.65 million each day. Regardless, when you pay $1.65 billion for a business, you probably don't expect it to take three to four years before you start making your money back."

VISA Pulls Plug On ePassporte, Porn Webmasters

tsu doh nimh writes "Credit card giant VISA International has suspended its business with ePassporte, an Internet payment system widely used to pay adult Webmasters and a raft of other affiliate programs. A number of adult Webmaster forums are up in arms over the move because many of their funds are now stranded. Visa has been silent on the issue so far, but KrebsOnSecurity.com points to an e-mail from ePassporte founder Christopher Mallick saying the unexpected move by Visa wouldn't strand customers indefinitely. Mallick co-directed Middle Men, a Paramount film released in August that tells the story of his experience building one of the world's first porn site payment processing firms, as well as the Russian mobsters, porn stars and FBI agents he ran into along the way. Interestingly, the speculation so far is that Visa cut ties with ePassporte due to new anti-money laundering restrictions in the Credit Card Act of 2009, which affects prepaid cards and other payment card instruments that can be reloaded with funds at places other than financial institutions."

New and Old Experiments Combine To Help the Search For Life On Mars

jamie sends in a story about an unexpected finding by the Phoenix Mars Lander which has shed new light on experiments done by the Viking landers back in 1976. The Viking experiments found traces of chlorine compounds that were interpreted to be the result of contamination from cleaning fluids on Earth. In 2008, an experiment done by Phoenix found percholates in the soil, which came as a surprise to researchers. After doing tests on similar soil from Chile, a new study has found that those percholates, paired with organic molecules, could very well be the source of the chlorine compounds detected by Viking. While this is not direct evidence for life on Mars, the fact that complex organic compounds can apparently persist in the Martian soil gives researchers a new avenue to pursue while looking for that evidence.

But now that it has lost out to Hewlett-Packard in the bidding war it started for 3Par, where does Dell go in its effort to diversify its business and move into the higher-profit area of selling technology to other companies? The company faces significant challenges, largely due to its lower-end focus, and because many of its competitors beat Dell into branching out. One analyst says, 'People see [Dell] as box-pushers'."

Anti-Google Video Runs In Times Square

Hugh Pickens writes "The NY Times reports that Consumer Watchdog is running a 540-square-foot video billboard advertisement in Times Square, New York that shows Google CEO Eric Schmidt as an ingratiating ice cream truck driver who knows everything about everyone and happily offers free ice cream in exchange for full body scans. The group says its goal is to push Congress and the Federal Trade Commission to create a Do Not Track Me list, similar to the Do Not Call list developed to prevent telemarketers from aggressively calling consumers. 'Do you want Google or any other online company looking over your shoulder and tracking your every move online just so it can increase its profits?' writes the group's president, Jamie Curtis, at the group's web site. 'Consumers have a right to privacy. They should control how their information is gathered and what it is used for.' The FTC's consumer affairs group had no comment on whether the agency is considering creating a Do Not Track Me list."

Duke Nukem Forever Back In Development

An anonymous reader writes "'Always bet on Duke.' It seems he was right about himself, at least. The longest, most storied in-development game in history seems like it's finally going to be released by Gearbox Software sometime within the next year. 'According to Pitchford, Gearbox began finishing Duke Nukem Forever in late 2009. "Clearly the game hadn't been finished at 3D Realms but a lot of content had been created," he says. "The approach and investment and process at 3D Realms didn't quite make it, and it cracked at the end. With Gearbox Software we brought all those pieces together. It's the game it was meant to be." The game is currently expected to ship in 2010 although given its history Pitchford is understandably reluctant to be more specific.'"

New Malware Imitates Browser Warning Pages

Jake writes with this excerpt from Ars: "Microsoft is warning about a new piece of malware, Rogue:MSIL/Zeven, that auto-detects a user's browser and then imitates the relevant malware warning pages from Internet Explorer, Firefox, or Chrome. The fake warning pages are very similar to the real thing; you have to look closely to realize they aren't the real thing. The ploy is a basic social engineering scheme, but in this case the malware authors are relying on the user's trust in their browser, a tactic that hasn't been seen before. Beyond the warning pages, the actual malware looks like the real deal: it allows you to scan files, tells you when you're behind on your updates, and enables you to change your security and privacy settings. Performing a scan results in the product finding malicious files, but of course it cannot delete them unless you update, which requires paying for the full version. Attempting to buy the product will open an HTML window that provides a useless 'Safe Browsing Mode' with high-strength encryption. To top it all off, the rogue antivirus webpage looks awfully similar to the Microsoft Security Essentials webpage; even the awards received by MSE and a link to the Microsoft Malware Protection Center have been copied."

Flawed iTunes Stands Out Among Apple's Products

waderoush writes "On top of all the other features that it has crammed into iTunes, Apple this week added Ping, a Facebook-like social network for music discovery. It's all part of the company's plan to dominate the world of consumer media, but Xconomy argues that this time, Apple may have gone a bridge too far. iTunes, nearing its tenth birthday, started out merely as a program for ripping CDs, and has grown increasingly creaky and impenetrable as Apple has added more and more cruft, the article argues. The company won't have a stable base for its new media empire until it rebuilds iTunes from scratch — perhaps along the lines suggested by its other new product this week, the revamped Apple TV."

Major Battle Brewing Between French Gov't and ISPs

Dangerous_Minds writes "Drew Wilson has been following HADOPI (France's three strikes law) a lot lately, and the latest developments are that the French ISPs and the French government are edging closer to a full-on war over compensation. The French government apparently requested that ISPs send an invoice of the bills after a certain period of time, but the French ISPs don't feel this is good enough — probably because of worries that the compensation the government will ultimately provide won't be enough. The ISPs are demanding adequate compensation, and if the government doesn't give it to them, they simply will not hand over evidence required to enforce HADOPI law. While HADOPI demands that ISPs cooperate, speculation suggests that if the government takes ISPs to court, the ISPs will simply rely on constitutional jurisprudence to shield them from liability (translation)."

In May we discussed news that producers of the film The Hurt Locker filed a lawsuit against 5,000 John Does, known only by their IP addresses at the time, for sharing the movie over peer-to-peer sites. Now, reader suraj.sun notes that subpoenas for the lawsuit are finally going out. "Qwest Communications on Monday notified a customer in Denver that the Internet service provider has received a subpoena from lawyers representing Voltage Pictures, the production company that made The Hurt Locker. ... In legal documents, Voltage Pictures has blamed the movie's relatively poor domestic performance on illegal file sharing. As of March 21, the movie had grossed $16 million domestically, but took in $40 million overall. According to reports, the film's production budget was $15 million. The film leaked to the Web five months before the movie's US debut. ... For allegedly downloading The Hurt Locker, DGW told the Qwest customer from Denver that settling the case early would cost $2,900, according to documents reviewed by CNET."

HP Backs Memristor Mass Production

neo12 writes with news that Hewlett-Packard is teaming with Hynix Semiconductor, the world's second-largest producer of memory chips, to mass produce memristors for the first time. Quoting the BBC: "HP says the first memristors should be widely available in about three years. The devices started as a theoretical prediction in 1971 but HP's demonstration and publication of a real working device has put them on a possible roadmap to replace memory chips or even hard drives. ... Steve Furber, professor of computer engineering at the University of Manchester, explained that the potential benefits lie in the fact that memristors are 'much simpler in principle than transistors. Because they are formed as a film between two wires, they don't have to be implanted into the silicon surface — as do transistors, which form the storage locations in Flash — so they could be built in layers in 3D,' he told BBC News. 'Of course, the devil is in the detail, and I don't think the manufacturing challenges have been fully exposed yet.'"

New Calculations May Lead To a Test For String Theory

dexmachina writes "A team of theoreticians, led by a group from Imperial College London, has released calculations that show string theory makes specific, testable predictions about the behaviour of quantum entangled particles. Professor Mike Duff, lead author of the study from the Department of Theoretical Physics at Imperial College London, commented, 'This will not be proof that string theory is the right "theory of everything" that is being sought by cosmologists and particle physicists. However, it will be very important to theoreticians because it will demonstrate whether or not string theory works, even if its application is in an unexpected and unrelated area of physics.' In other words, string theory may finally have shed its critics' most common complaint: unfalsifiability. However, given the second most common complaint, I can't help but wonder: which string theory?"

Harvard Ditching Final Exams?

itwbennett writes "According to Harvard magazine, Harvard's Faculty of Arts and Sciences voted at its meeting on May 11 to require instructors to officially inform the Registrar 'at the first week of the term' of the intention to end a course with a formal, seated exam, 'the assumption shall be that the instructor will not be giving a three-hour final examination.' Dean of undergraduate education Jay M. Harris 'told the faculty that of 1,137 undergraduate-level courses this spring term, 259 scheduled finals — the lowest number since 2002, when 200 fewer courses were offered. For the more than 500 graduate-level courses offered, just 14 had finals, he reported.'"

Flash On Android Is 'Shockingly Bad'

Hugh Pickens writes "Ryan Lawler writes on GigaOm that although many have touted the availability of Flash on Android devices as a competitive advantage over Apple's mobile devices, while trying to watch videos from ABC.com, Fox.com and Metacafe using Flash 10.1 on a Nexus One over a local Wi-Fi network connected to a 25-Mbps Verizon FiOS broadband connection, mobile expert Kevin Tofel found that videos were slow to load, if they loaded at all, leading to an overall very inconsistent experience while using his Android device for video. 'While in theory Flash video might be a competitive advantage for Android users, in practice it's difficult to imagine anyone actually trying to watch non-optimized web video on an Android handset,' writes Lawler. 'All of which makes one believe that maybe Steve Jobs was right to eschew Flash in lieu of HTML5 on the iPhone and iPad.'"

Video Appliance For a Large Library On a Network?

devjj writes "For the past year or so I have been trying (and failing) to figure out a reasonable solution for bringing my large media library to my living room. All of my media lives on an Ubuntu server that sits on my network. It's been very reliable and it's fast enough for streaming purposes. My content is exposed via SMB. It's the living room side where I keep running into problems. I am currently using Windows 7 and XBMC, but the case is too big and noisy, I don't particularly care for Windows, and the whole thing just seems overkill. What I want is a device that can present a decent UI that the non-Slashdot crowd would be able to use, but that is still powerful enough to stream full-fidelity 1080p. I dream of a small box that can transcode video over a network, but that's probably a pipe dream. The new Apple TV would be great if it could connect to network shares. What say you, Slashdot? Is what I'm looking for possible, or should I just give in to the iTunes/Amazon/whatever juggernauts?"

Canon Develops 8 X 8 Inch Digital CMOS Sensor

dh003i writes "Canon has developed a 8 x 8 inch CMOS digital sensor. It will be able to capture an image with 1/100th the light intensity required by a DSLR and will be able to record video at 60 fps in lighting half the intensity of moonlight. There are already many excellent quality lenses designed to cover 8 x 10 inches, although Canon may develop some of their own designed specifically for their requirements."
