coop0030 writes "The first photos and videos of the Model A production samples are now available. The Raspberry Pi Model A is the newest low-cost computer from the Raspberry Pi Foundation. Compared to the popular Model B, the Model A forgoes the Ethernet Controller, has 256MB of RAM, and has a single USB port. A benefit of the missing Ethernet controller is that power consumption is reduced. This allowed them to reach their goals of a low-cost $25 computer. The release date is for sometime early in 2013."
itwbennett writes "In an official document that is both 'confidential' and publicly available on Oracle's website, the company lays out its cloud policies. Most of the policies follow industry standards, but then there are a few that should give customers pause. Like the one that allows Oracle to turn off access to accounts in the event of a dispute or account violation."
An anonymous reader writes "It's been found that the Btrfs file-system is vulnerable to a Hash-DOS attack, a denial-of-service attack caused by hash collisions within the file-system. Two DOS attack vectors were uncovered by Pascal Junod that he described as causing astonishing and unexpected success. It's hoped that the security vulnerability will be fixed for the next Linux kernel release." The article points out that these exploits require local access.
An anonymous reader writes "Google on Friday announced it is shutting down a slew of features and services as part of its winter cleaning. Google Calendar will be losing a few features, Google Sync will be axed (on the consumer side), as will Google Calendar Sync, SyncML, the Issue Tracker Data API, and the Punchd app."
TaeKwonDood writes with news from CERN about more results in the search for the Higgs Boson, this time from the ATLAS experiment. Researchers report peaks in the data in accordance with what they'd expect from the Higgs. The curiosity is that the peaks are a couple GeV away from each other. "The ATLAS analyses in these channels return the best fit Higgs masses that differ by more than 3 GeV: 123.5 GeV for ZZ and 126.6 GeV for gamma-gamma, which is much more than the estimated resolution of about 1 GeV. The tension between these 2 results is estimated to be 2.7sigma. Apparently, ATLAS used this last month to search for the systematic errors that might be responsible for the discrepancy but, having found nothing, they decided to go public." Scientific American has a more layman-friendly explanation available. As this work undergoes review, physicists hope more eyes and more data will shed some light on this incongruity. Tommaso Dorigo, a particle physicist working at the CMS experiment at CERN, writes, "Another idea is that the gamma-gamma signal contains some unexpected background which somehow shifts the best-fit mass to higher values, also contributing to the anomalously high signal rate. However, this also does not hold much water — if you look at the various mass histograms produced by ATLAS (there is a bunch here) you do not see anything striking as suspicious in the background distributions. Then there is the possibility of a statistical fluctuation. I think this is the most likely explanation." Matt Strassler provides a broader update to the work proceeding on nailing down the Higgs boson.
EdIII writes "The White House petition to secure funding for building the Death Star has garnered over 25,000 signatures, which means the White House must officially respond. I can't wait to see it. My question to Slashdot readers: what modifications would you add to the proposed Death Star? Obviously, as one journalist put it, 'guardrails around any of the facility's seemingly endless number of bridges, spans, shafts and pits.' What other changes would you ask your representatives to make?"
skade88 writes "Worldwide, people are living longer. Their lives are starting to look more like the lives of Americans: too much food is a problem, death in childhood is becoming less common, and so on. Yet with a population that lives through what would once have killed us, disabilities are starting to become the norm. A research report from the Institute for Health Metrics and Evaluation has a good glimpse into the new emerging world we find ourselves in." The Guardian has a nice visualization of the mortality data (but take note of shifting scales on the Y-axis).
dcblogs writes "Michigan lawmakers just approved a right-to-work law in an effort to dismantle union power, but unions are already becoming irrelevant. The problem with unions is they can't protect jobs. They can't stop a company from moving jobs overseas, closing offices, or replacing workers with machines. Indeed, improvements in automation is making the nation attractive again for manufacturing, according to U.S. intelligence Global Trends 2030 report. The trends are clear. Amazon spent $775 million this year to acquire a company, Kiva Systems that makes robots used in warehouses. Automation will replace warehouse workers, assembly-line and even retail workers. In time, Google's driverless cars will replace drivers in the trucking industry. Unions sometimes get blamed for creating uncompetitive environments and pushing jobs overseas. But the tech industry, which isn't unionized, is a counterpoint. Tech has been steadily moving jobs overseas to lower costs."
Nerval's Lobster writes "Are e-readers doomed? A research note earlier this week from IHS iSuppli suggested that, after years of solid growth, the e-book reader market was 'on an alarmingly precipitous decline' thanks to the rise of tablets. The firm suggested that e-reader sales had declined from 23.2 million units in 2011 to 14.9 million this year — around 36 percent, in other words. The note blames tablets: 'Single-task devices like the ebook are being replaced without remorse in the lives of consumers by their multifunction equivalents, in this case by media tablets.' Even Amazon and Barnes & Noble, the reigning champs of the e-reader marketplace, have increasingly embraced full-color tablets as the best medium for selling their digital products. Backed by enormous cloud-based libraries that offer far more than just e-books, these devices are altogether more versatile than grayscale e-readers, provided their users want to do more than just read plain text."
yanom writes "I'm currently a high school student using my TI-84 for mathematics courses. It has all the functionality I need (except CAS), but saying that the hardware is dated is putting it nicely. Waiting 4-5 seconds for a simple function to be graphed on its 96x64 screen just makes me want to hurl it at the wall. Recently, I've begun to notice the absurdity of doing my math homework on a 70's era microchip when I have an i7 machine with Linux within arm's reach. I've begun looking for software packages that could potentially replace the graphing calculator's functionality, including Xcas and Maxima, but both lack what I consider basic calculator functionality — xcas can't create a table of values for a function, and maxima can't use degrees, only radians. So, does anyone know of a good software package to replace my graphing calculator (and maybe provide CAS to boot)?"
SternisheFan sends this story from the Baltimore Sun: "The Baltimore City speed camera ticket alleged that the four-door Mazda wagon was going 38 miles per hour in a 25-mph zone — and that owner Daniel Doty owed $40 for the infraction. But the Mazda wasn't speeding. It wasn't even moving. The two photos printed on the citation as evidence of speeding show the car was idling at a red light with its brake lights illuminated. A three-second video clip also offered as evidence shows the car motionless, as traffic flows by on a cross street. Since the articles' publication, several lawmakers have called for changes to the state law that governs the way the city and other jurisdictions operate speed camera programs. Gov. Martin O'Malley said Tuesday that state law bars contractors from being paid based on the number of citations issued or paid —an approach used by Baltimore City, Baltimore County, Howard County and elsewhere. 'The law says you're not supposed to charge by volume. I don't think we should charge by volume,' O'Malley said. "If any county is, they need to change their program.'"
CowboyRobot writes "Byte magazine gives a run-down of the current state of Internet access on airplanes. 'All of the services function in basically the same way. They provide connectivity to the public Internet via a Wi-Fi hotspot accessible from the cabin of the aircraft. This in-cabin network may also be used to provide in-flight entertainment services ranging from television network feeds to movies and canned TV shows available from an on-board media server connected to the network. In the U.S., the Internet connectivity is available when the aircraft is above 10,000 feet and is turned off during take-offs and landings. Gogo, the current market leader, provides connectivity to aircraft via a network of 250 dedicated cell towers that it has built nationwide. Fundamentally, it offers the same type of connectivity you would expect to see on a standard 3G-capable phone. The connection is limited in speed to just over 3 Mbps — and all users on the plane share this one connection.'"
Several readers sent word of a shooting at an elementary school in Newtown, Connecticut. According to most reports, 27 people are dead, including 18 children. The alleged shooter is dead, a man in his 20s. He was armed with multiple weapons and may have worn a bulletproof vest. According to CBS, "It is unclear if there was more than one gunman at the school. Miller reports authorities have an individual in custody who investigators said may be a possible second shooter." (Investigators now say the person being questioned is not a suspect.) One student was quoted as saying, "I was in the gym and I heard a loud, like seven loud booms, and the gym teachers told us to go in the corner, so we all huddled. And I kept hearing these booming noises. And we all started crying." Another, 8 years old, said, "I saw some of the bullets going down the hall and then a teacher pulled me into her classroom."
An anonymous reader writes "Researchers of the International Computer Science Institute in Berkeley have created an interactive diagram that shows root-CAs, their intermediates, the relationships between them and how many certificates have been signed by them. The graph was generated by passively monitoring the Internet uplinks of a number of (mostly) edu sites for SSL connections and their certificate Information. Among other things the graph shows that one GoDaddy intermediate signed more than 74,000 certificates and that a German CA uses more than 200 sub-CAs for administrative reasons."
