Death Metal writes "In a working paper titled, 'Is Tom Cruise Threatened? Using Netflix Prize Data to Examine the Long Tail of Electronic Commerce,' Wharton Operations and Information Management professor Serguei Netessine and doctoral student Tom F. Tan pull information from the movie rental company Netflix to explore consumer demand for smash hits and lesser-known films. Netflix made its data available as part of a $1 million prize competition to encourage the development of new ways that will improve its ability to introduce customers to lesser-known titles they might find appealing." In short, the researchers say that the Long Tail effect described by Chris Anderson is much less important in the real world than popularly held. Says the article: "The key difference between the opinion of [Anderson's] book and the study by Wharton researchers is how they define 'hits' and 'niches.' In the book, Anderson focuses on the definition of hits in absolute terms such as the top 10 or top 1,000 products, while Netessine and Tan argue that, to take growing product variety into account, one has to define popularity in relative terms, such as the top 1% or top 10% of products, to properly assess the presence or absence of the Long Tail."

Death Metal writes "While everyone would like to work for a nice person who is always right, IT pros will prefer a jerk who is always right over a nice person who is always wrong. Wrong creates unnecessary work, impossible situations and major failures. Wrong is evil, and it must be defeated. Capacity for technical reasoning trumps all other professional factors, period."

Death Metal writes with this excerpt from ComputerWeekly.com about the UK's national ID card scheme: "Privacy advocates have reacted angrily to reports that the government plans to link national identity records to criminal records for background checks on people who work with children and vulnerable people. Up to 11 million such workers could be affected immediately if the plan goes ahead. Phil Booth, national co-ordinator of privacy advocates NO2ID, said the move was consistent with the various forms of coercion strategy to create so-called volunteers for national ID cards. 'Biometrics are part of the search for clean, unique identifiers,' Phil Booth said. He said the idea was patently ridiculous when the Home Office was planning to allow high street shops and the Post Office to take fingerprints for the ID card."

Death Metal writes "Psychologists at the University of California, Los Angeles say the human body has a gene that connects physical pain sensitivity with social pain sensitivity. The findings back the common theory that rejection 'hurts' by showing that a gene regulating the body's most potent painkillers — mu-opioids — is involved in socially painful experiences too."

Death Metal writes "The phone network is thus not just a technical infrastructure, but a socioeconomic one. The more Americans abandon it to go mobile-only or make phone calls over the Internet, the more fragile it becomes: its high fixed costs have to be spread over ever fewer subscribers. If the telephone network in New York State were a stand-alone business, it would already be in bankruptcy. In recent years it has lost 40% of its landlines and revenues have dropped by more than 30%."

Death Metal sends along this excerpt from Torrentfreak about how Global Gaming Factory, the company who is buying The Pirate Bay, plans to change the site in order to avoid the wrath of the entertainment industry: "In a letter addressed to [shareholders], the company confirms that the new Pirate Bay will become a pay site, while revealing some additional details on how GGF plans to legalize it. To please the entertainment industry, GGF will install a system that will allow the copyright holders to either authorize the 'illegal' torrent or have it removed from the site. If the copyright holder chooses the first option, they will be compensated every time the file is downloaded. In addition, the board says that it will pay penalties if it has to. 'The holder will be able to leave the file and obtain compensation or ask for removal of the file. GGF will also pay any penalties that may arise,' the GGF board announced."

Death Metal sends word that the owners of URL-shortening service tr.im are in the process of releasing the project's source code and moving it into the public domain. This comes after reports that the service may shut down and that they were entertaining offers from prospective buyers. From a post on the site's blog: "It is our hope that tr.im, being an excellent URL shortener in its own right, can now begin to stand in contrast to the closed twitter/bit.ly walled garden: it will become a completely open solution owned and operated by the community for the benefit of the entire community." They plan to complete the transition by September 15th, and the code will be released under the MIT license. In addition, "tr.im will offer all link-map data associated with tr.im URLs to anyone that wants it in real-time. This will involve a variety of time-based snapshots of aggregated destination URLs, the number of tr.im URLs created for any given destination URL, and aggregate click data."

Death Metal writes "Eating fatty food appears to take an almost immediate toll on both short-term memory and exercise performance, according to new research on rats and people. Other studies have suggested that that long-term consumption of a high-fat diet is associated with weight gain, heart disease and declines in cognitive function. But the new research shows how indulging in fatty foods over the course of a few days can affect the brain and body long before the extra pounds show up."

Death Metal points out a CNet report saying that the Justice Department has come out in favor of the $1.92 million verdict awarded to the RIAA in the Jammie Thomas-Rasset case. Their support came in the form of a legal brief filed on Friday, which notes, "Congress took into account the need to deter the millions of users of new media from infringing copyrights in an environment where many violators believe that they will go unnoticed." It also says, "The Copyright Act's statutory damages provision serves both to compensate and deter. Congress established a scheme to allow copyright holders to elect to receive statutory damages for copyright infringement instead of actual damages and profits because of the difficulty of calculating and proving actual damages."

Death Metal writes with this excerpt from CNN: "About 30 children aged 3 to 12 years old and their parents are participating in a new program that uses DNA testing to identify genetic gifts and predict the future. ... The test is conducted by the Shanghai Biochip Corporation. Scientists claim a simple saliva swab collects as many as 10,000 cells that enable them to isolate eleven different genes. By taking a closer look at the genetic codes, they say they can extract information about a child's IQ, emotional control, focus, memory, athletic ability and more. For about $880, Chinese parents can sign their kids up for the test and five days of summer camp in Chongqing, where the children will be evaluated in various settings from sports to art. The scientific results, combined with observations by experts throughout the week, will be used to make recommendations to parents about what their child should pursue."

Death Metal writes with this excerpt from Computer Weekly, which casts some doubt on the security of the UK's proposed personal identification credential: "The prospective national ID card was broken and cloned in 12 minutes, the Daily Mail revealed this morning. The newspaper hired computer expert Adam Laurie to test the security that protects the information embedded in the chip on the card. Using a Nokia mobile phone and a laptop computer, Laurie was able to copy the data on a card that is being issued to foreign nationals in minutes."

Death Metal writes "Iranians seeking to share videos and other eyewitness accounts of the demonstrations that have roiled their country since disputed elections two weeks ago are using an Internet encryption program originally developed by and for the US Navy. Designed a decade ago to secure Internet communications between US ships at sea, The Onion Router, or TOR, has become one of the most important proxies in Iran for gaining access to Web sites such as Twitter, YouTube and Facebook." A related story was submitted anonymously about the efforts of hactivists to keep the information flowing inside the data-locked nation.

Death Metal writes "All of Earth's people, according to a new analysis of the genomes of 53 populations, fall into just three genetic groups. They are the products of the first and most important journey our species made — the walk out of Africa about 70,000 years ago by a small fraction of ancestral Homo sapiens."

Death Metal tips news about how defense contractor Raytheon is adapting military-style surveillance packages for use aboard blimps at public events like the Indy 500. "Until recently, Raytheon's eye-in-the-sky technology was used in Afghanistan and Iraq to guard American military bases, working as airborne guards against any oncoming desert threat. Using infrared sensors and a map overlay not unlike Google Earth, the technology scans a large area, setting important landmarks (say, the perimeter of a military base), and constantly relays video clips back to a command center. If a gun fires or a bomb is detonated, the airships can detect the noise and focus the camera — all from a mighty-high 500 feet." Though the technology is expensive, Raytheon is shopping it around to police departments and other organizations that might want to keep an eye on large gatherings of people.

Death Metal sends in a story about Kyle Brady, a computer science major at San Jose State University, who recently ran into trouble over publishing the source code to his programming assignments after their due dates. One of Brady's professors contacted him and threatened to fail him if he did not take down the code. Brady took the matter to the Computer Science Department Chair, who consulted with others and decided that releasing the code was not an ethical violation. Quoting Cory Doctorow at Boing Boing: "There's a lot of meat on the bones of this story. The most important lesson from it for me is that students want to produce meaningful output from their course-assignments, things that have intrinsic value apart from their usefulness for assessing their progress in the course. Profs — including me, at times — fall into the lazy trap of wanting to assign rotework that can be endlessly recycled as work for new students, a model that fails when the students treat their work as useful in and of itself and therefore worthy of making public for their peers and other interested parties who find them through search results, links, etc. But the convenience of profs must be secondary to the pedagogical value of the university experience — especially now, with universities ratcheting up their tuition fees and trying to justify an education that can put students into debt for the majority of their working lives."

Death Metal writes "The EU passed the Data Retention Directive years ago, a law that demands ISPs and search engines hold onto data long enough to help the cops (but not long enough to cause privacy problems). But Sweden never passed it into national law, and the European Commission has now sued the country to make sure a bill appears."

Death Metal suggests we peruse a piece up at Wired on how the Obama administration's draft guidelines for stem cell research could invalidate hundreds of cell lines. "Under the Obama administration's proposed rules for funding embryonic stem cell research, hundreds of existing cell lines could be ineligible, even those that qualified under President Bush. The guidelines were written by the National Institutes of Health and are currently in draft form and expected to be finalized in July. But in their current state, they restrict funding to stem cell lines produced according to new rules that are only now being established. Few existing cell lines will meet those requirements. 'The so-called Presidential lines aren't suitable for actual medical application,' said Patrick Taylor, deputy counsel at Children's Hospital Boston, who criticized the NIH guidelines in a paper published Thursday in Cell Stem Cell. 'But we're talking about many, many more lines. The new lines were created with extensive ethical oversight. They're at stake here.'"

Death Metal writes with an excerpt from the website of defense attorney Evan Levow: "After two years of attempting to get the computer based source code for the Alcotest 7110 MKIII-C, defense counsel in State v. Chun were successful in obtaining the code, and had it analyzed by Base One Technologies, Inc. By making itself a party to the litigation after the oral arguments in April, Draeger subjected itself to the Supreme Court's directive that Draeger ultimately provide the source code to the defendants' software analysis house, Base One. ... Draeger reviewed the code, as well, through its software house, SysTest Labs, which agreed with Base One, that the patchwork code that makes up the 7110 is not written well, nor is it written to any defined coding standard. SysTest said, 'The Alcotest NJ3.11 source code appears to have evolved over numerous transitions and versioning, which is responsible for cyclomatic complexity.'" Bruce Schneier comments on the same report and neatly summarizes the take-away lesson: "'You can't look at our code because we don't want you to' simply isn't good enough."

Death Metal notes an EFF report on information wrested from the FBI over the last three years via Freedom of Information requests. The report characterizes what Ars Technica calls the FBI's "Everything Bucket" — its Investigative Data Warehouse. (Here's the EFF's introduction and the report itself.) The warehouse, at least 7 years in the making, "...appears to be something like a combination of Google and a university's slightly out-of-date custom card catalog with a front-end written for Windows 2000 that uses cartoon icons that some work-study student made in Microsoft Paint. I guess I'm supposed to fear the IDW as an invasion of privacy, and indeed I do, but given the report's description of it and my experiences with the internal-facing software products of large, sprawling, unaccountable bureaucracies, I mostly just fear for our collective safety."

Death Metal tips news that the Irish government has announced their decision to abandon e-voting and return to a paper-based system. "Ireland has already put about $67 million into building out its e-voting infrastructure, but the country has apparently decided that it would be even more expensive to keep going with the system than it would be to just scrap it altogether." John Gormley, Ireland's Minister for the Environment, Heritage and Local Government, said, "It is clear from consideration of the Report of the Commission on Electronic Voting that significant additional costs would arise to advance electronic voting in Ireland. ... the assurance of public confidence in the democratic system is of paramount importance and it is vital to bring clarity to the present situation." He added that he still thinks there is a need for electoral reform.

Death Metal sends this excerpt from an AP report: "General Dynamics Information Technology put out an ad last month on behalf of the Homeland Security Department seeking someone who could 'think like the bad guy.' Applicants, it said, must understand hackers' tools and tactics and be able to analyze Internet traffic and identify vulnerabilities in the federal systems. In the Pentagon's budget request submitted last week, Defense Secretary Robert Gates said the Pentagon will increase the number of cyberexperts it can train each year from 80 to 250 by 2011. With warnings that the US is ill-prepared for a cyberattack, the White House conducted a 60-day study of how the government can better manage and use technology (PDF) to protect everything from the electrical grid and stock markets to tax data, airline flight systems, and nuclear launch codes. ... Nadia Short, vice president at General Dynamics Advanced Information Systems, said the job posting for ethical hackers fills a critical need for the government."

Death Metal writes "PC-BSD 7.1 is built upon the FreeBSD 7.1-STABLE operating system. FreeBSD is a UNIX-based operating system that provides a high level of security and stability. The Galileo Edition of PC-BSD includes updated versions of KDE (4.2.2) and Xorg (7.4). The latest version of KDE includes new window effects, screen savers, and better 3D Acceleration. PC-BSD exclusively features the Push Button Installer, a software installation wizard with a wide range of applications. The latest version improves PBI self-containment to increase reliability. The Add / Remove Programs tool and the Update Manager have been consolidated into 'Software & Updates.'"

Death Metal writes with this excerpt from a story about COBOL's influence as it approaches 50 years in existence: "According to David Stephenson, the UK manager for the software provider Micro Focus, 'some 70% to 80% of UK plc business transactions are still based on COBOL.' ... Mike Gilpin, from the market research company Forrester, says that the company's most recent related survey found that 32% of enterprises say they still use COBOL for development or maintenance. ... A lot of this maintenance and development takes place on IBM products. The company's software group director of product delivery and strategy, Charles Chu, says that he doesn't think 'legacy' is pejorative. 'Business constantly evolves,' he adds, 'but there are 250bn lines of COBOL code working well worldwide. Why would companies replace systems that are working well?'"

Death Metal writes to tell us that a growing tide of complaints are being piled at Google's feet in response to a far-reaching settlement that some feel will grant the giant too much power over the "orphan books" they have been scanning into digital format. The settlement could give Google near-exclusivity with respect to the copyright of orphan works — books that the author and publisher have essentially abandoned. They are out of print, and while they remain under copyright, the rights holders are unknown or cannot be found. "Critics say that without the orphan books, no competitor will ever be able to compile the comprehensive online library Google aims to create, giving the company more control than ever over the realm of digital information. And without competition, they say, Google will be able to charge universities and others high prices for access to its database. The settlement, 'takes the vast bulk of books that are in research libraries and makes them into a single database that is the property of Google,' said Robert Darnton, head of the Harvard University library system. 'Google will be a monopoly.'"

Death Metal sends along an Ars Technica piece about The Pirate Bay's plans for a virtual private network service to help ensure its users' privacy. "The Pirate Bay is planning to launch a paid VPN service for users looking to cover their tracks when torrenting. The new service will be called IPREDator, named after the Swedish Intellectual Property Rights Enforcement Directive (IPRED) that will go into effect in April. IPREDator is currently in private beta and is expected to go public next week for €5 per month. ... IPREDator's website says that it won't store any traffic data, as its entire goal is to help people stay anonymous on the web. Without any data to hand over, copyright owners won't be able to find individuals to target. ... The question remains, however, if any significant portion of The Pirate Bay's users will decide to fork over 5 Euro per month solely to remain anonymous. It seems more likely that the majority either won't care, or will simply start looking for lesser-known torrent trackers to use."

Death Metal writes "Chief Security Engineer Andrea Barisani and hardware hacker Daniele Bianco used handmade laser microphone device and a photo diode to measure the vibrations, software for analyzing the spectrograms of frequencies from different keystrokes, as well as technology to apply the data to a dictionary to try to guess the words. They used a technique called dynamic time warping that's typically used for speech recognition applications, to measure the similarity of signals. Line-of-sight on the laptop is needed, but it works through a glass window, they said. Using an infrared laser would prevent a victim from knowing they were being spied on." (This is the same team that was able to pick up the electromagnetic signals emitted by PS/2 keyboards.)

Death Metal writes with this excerpt from Ars Technica: "If there were any doubt that open access publishing was setting off a bit of a power struggle, a decision made last week by the MIT faculty should put it to rest. Although most commercial academic publishers require that the authors of the works they publish sign all copyrights over to the journal, Congress recently mandated that all researchers funded by the National Institutes of Health retain the right to freely distribute their works one year after publication (several foundations have similar requirements). Since then, some publishers started fighting the trend, and a few members of Congress are reconsidering the mandate. Now, in a move that will undoubtedly redraw the battle lines, the faculty of MIT have unanimously voted to make any publications they produce open access."

Death Metal Maniac tips an Ars Technica piece suggesting that the media's coverage of Vista's flaws portrayed the operating system as worse than it was, and, if early reports on Windows 7 are any indication, positive hype will create the opposite reaction this time around. Quoting: "... the problem is exaggeration; ... bloggers and journalists alike use their personal experiences to prove their point in their writing. The blame doesn't solely lie with us, as Vista was by no means perfect, but we did manage to amplify the problems beyond reason. And if the beta is anything to go by, Windows 7 is going to fly. This is, by far, the best beta operating system the software giant has ever released. The media has locked on to this, and is using exaggeration already, before Windows 7 is even ready for prime time." Apparently a decent beta can succeed where $300 million and Jerry Seinfeld failed.

Anti-Globalism writes "A group of hippies is complaining that a recently installed WiFi mesh network in the UK village of Glastonbury is causing health problems. To combat the signals from the Wi-Fi hotspots, the hippies have placed orgone generators around the antennae." Although there have been many studies that show no correlation between WiFi and health issues the hippies say, "Yeah, well, you know, that's just, like, your opinion, man."

Death Metal writes "Companies in Europe have begun to roll out an advanced biometric system from Japan that identifies people from the unique patterns of veins inside their fingers. Finger vein authentication, introduced widely by Japanese banks in the last two years, is claimed to be the fastest and most secure biometric method. Developed by Hitachi, it verifies a person's identity based on the lattice work of minute blood vessels under the skin."

Death Metal sends in a Scientific American article reporting that 2,000 of 6,000 amphibian species are endangered worldwide. A combination of environmental assaults, including global warming, seems to be responsible. "... national parks and other areas protected from pollution and development are providing no refuge. The frogs and salamanders of Yellowstone National Park have been declining since the 1980s, according to a Stanford University study, as global warming dries out seasonal ponds, leaving dried salamander corpses in their wake. Since the 1970s, nearly 75 percent of the frogs and other amphibians of La Selva Biological Station in Braulio Carrillo National Park in the Caribbean lowlands of Costa Rica have died, perhaps due to global warming. But the really bad news is that amphibians may be just the first sign of other species in trouble. Biologists at the University of California, San Diego, have shown that amphibians are the first to respond to environmental changes, thanks to their sensitivity to both air and water. What goes for amphibians may soon be true of other classes of animal, including mammals."

Death Metal writes "Browser maker Opera has published the early results of an ongoing study that aims to provide insight into the structure of Internet content. To conduct this research project, Opera created the Metadata Analysis and Mining Application (MAMA), a tool that crawls the web and indexes the markup and scripting data from approximately 3.5 million pages."

Death Metal notes a Wired piece on the US government beginning the process of securing the root zone file. This is in service of implementing DNSSEC, without which the DNS security hole found by Dan Kaminsky can't be definitively closed. On Thursday morning, a comment period will open on the various proposals on who should hold the keys and sign the root — ICANN, Verisign, or the US government's NTIA.

Death Metal Maniac sends along a link from TorrentFreak on the latest development in game developer Topwear's battle against file sharers in the UK. "US game developer Topware Interactive, the people behind the now infamous Dream Pinball affair, are about to turn up the heat. Operating through London lawyers Davenport Lyons, they have managed to convince the High Court to send out an order demanding that ISPs in the UK start to hand over the details of several thousand alleged pirates ... BT, one of the UK's largest ISPs ..., confirmed it had been ordered to hand over details of alleged copyright infringing file-sharers ... Virgin Media was a little more slippery in its response but reading between the lines it seems obvious they are involved too."

Death Metal Maniac writes "Dubbed Eva de Naharon, or Eve of Naharon, the female skeleton has been dated at 13,600 years old. If that age is accurate, the skeleton along with three others found in underwater caves along the Caribbean coast of the Yucatán Peninsula could provide new clues to how the Americas were first populated. The skeletons' skulls hint that the people may not be of northern Asian descent, which would contradict the dominant theory of New World settlement. 'The shape of the skulls has led us to believe that Eva and the others have more of an affinity with people from South Asia than North Asia,' González explained."

Death Metal Maniac writes "The study, which was conducted by affordable-broadband advocacy group Speed Matters, found that the nine states with the fastest median download connections are all located on the East Coast. Rhode Island (6.8Mbps) and Delaware (6.7Mbps) have the fastest, and nearly triple the national median download speed of 2.3Mbps. Rounding out the Top 5 states are New Jersey (5.8Mbps), Virginia (5Mbps) and Massachusetts (4.6Mbps)."

We've been discussing the plight of Internet radio for some time, as the Copyright Royalty Board imposed royalties that industry observers predicted would prove lethal to the nascent industry. We discussed Web radio's day of silence in protest, which won the industry a reprieve, and the futile efforts to find relief in Congress. Now it's looking as if the last act is indeed close. Death Metal Maniac sends along this Washington Post story with extensive quotes from Pandora CEO Tim Westergren, who said: "The moment we think this problem in Washington is not going to get solved, we have to pull the plug because all we're doing is wasting money... We're funded by venture capital. They're not going to chase a company whose business model has been broken." The article estimates that XM Satellite Radio will pay "about 1.6 cents per hour per listener when the new rates are fully adapted in 2010. By contrast, Web radio outlets will pay 2.91 cents per hour per listener." That's 70% of projected revenue for Pandora; smaller players estimate the hit at 100% to 300% of revenue.

Death Metal Maniac writes "The team analyzed the DNA of 13 genes from Neanderthal mitochondria and found they were distinctly different from modern humans, suggesting Neanderthals never, or rarely, interbred with early humans. The genetic material shows that a Neanderthal 'Eve' lived around 660,000 years ago, when the species last shared a common ancestor with humans. Neanderthal brains were on average larger than those of modern humans."

Death Metal Maniac writes "New microchip passports designed to be foolproof against identity theft failed the test when a researcher was able to manipulate one in minutes. The cloned passports were accepted as genuine by the computer software recommended for use at international airports. According to the article: 'A computer researcher cloned the chips on two British passports and implanted digital images of Osama bin Laden and a suicide bomber. The altered chips were then passed as genuine by passport reader software used by the UN agency that sets standards for e-passports.'"
