Could Curiosity Rover Moonlight As Part of a Sample Return Mission? 65

pigrabbitbear writes "After recent budget cuts to NASA's Mars program, the agency's dream of a sample return mission within the next decade is dead in the water. But the $2.5 billion rover Curiosity is on its way to the red planet right now, and speculation is popping up online that it could fairly easily be retrofitted with the hardware needed to collect and store samples. Theoretically NASA would just need one more mission to collect and return those samples, turning Curiosity into the first phase of the sample return dream."

A Taxonomy of Visualization Techniques 26

CowboyRobot writes "The ACM's Queue magazine has a new, comprehensive taxonomy of visualization techniques, drawing from the theories of Edward Tufte and citing examples from academia, government, and the excellent NYT visualization team. This list contains 12 steps for turning data into a compelling visualization: Visualize, Filter, Sort, Derive, Select, Navigate, Coordinate, Organize, Record, Annotate, Share, & Guide. 'For developers, the taxonomy can function as a checklist of elements to consider when creating new analysis tools.' The citations alone make this an article worth bookmarking."

FCC Inquires Into Its Own Authority To Regulate Communication Service Shutdowns 112

New submitter DnaK writes "The Federal Communications Commission is reviewing whether or when the police and other government officials can intentionally interrupt cellphone and Internet service to protect public safety. A scary proposition which will easily become a First Amendment issue. Does the FCC have the authority to [regulate local or state authorities' decision to] take down cellular networks if they determine there is an imminent threat? The FCC is currently asking for public input (PDF) on this decision." According to the article, "among the issues on which the F.C.C. is seeking comment is whether it even has authority over the issue. The public notice asks for comment on whether the F.C.C. itself has legal authority over shutdowns of wireless service and whether it can pre-empt local, state or federal laws that prohibit or constrain the ability of anyone to interrupt service." Maybe they just don't like being upstaged by BART.

How Publishers Learned To Stop Worrying and Love Zite's Aggregator 22

waderoush writes "In March 2011, personalized-magazine startup Zite got a cease-and-desist letter from a group of 11 media giants outraged by the way Zite's popular iPad app 'misappropriated' their news articles. By August 2011, Zite had become part of CNN, which is owned by Time Warner, one of the organizations behind the C&D letter. Zite's brief clash with the media establishment, followed by its swift assimilation into the same establishment, is emblematic of a larger story unfolding in the media business: the grudging acknowledgement by publishers that readers want to access their content in new ways. In this article Zite CEO Mark Johnson explains how the startup mollified publishers (by presenting articles in 'Web view' mode rather than a stripped-down 'reader mode'), why CNN bought the company, and how it strives to make reading more enjoyable while still respecting publishers' business models."

Government Should Ban Skinny Models To Curb Anorexia, Say Researchers 676

smoothjazz writes "Governments are justified to prevent very skinny models from walking the catwalk and ban photographs and advertisements suggesting that extreme thinness is attractive, according to a group of researchers who found that social and cultural environment influences on young women is largely responsible for the spread of chronic eating disorder."

Is It Time For Hacker Scouts? 186

ptorrone writes "MAKE Magazine asks: is it 'Time For Girl Scouts and Boy Scouts 2.0?' What might the future of education be like if it were based on online & earned skill badges, and what could the future of traditional organizations for kids, like the Boy Scouts and Girl Scouts, be like in a very modern, tech-savvy world? Social networks and the maker movement are the perfect intersection of where the kids of today are, but we don't see 'leaderboards' for skills yet; we only see them for video games. Is it time for Hacker Scouts?"

Leaked Assassin's Creed 3 Screenshots Show American Revolution 100

An anonymous reader writes "After three years, Ubisoft is finally finishing the newest installment of their Templars vs. Assassins series, set during the American Revolution. PC Magazine reports that 'If the cover art is any indicator, the new Assassin is pals with George Washington, Paul Revere, Ben Franklin, and the other leading American revolutionaries of the day.' A team of developers at Ubisoft reportedly dedicated a full three-year development cycle to re-examining every element in the franchise to improve the game — although it could've taken even longer."

Car Hacking Concerns On the Rise 95

Pat Attack writes "I think most of the people who read Slashdot know that if it has circuitry, it can be hacked. Well, the good folks over at CNN have an article about the potential for your car to be hacked. This article lists the potential damage that could be done, proof of concept work, as well as a few scary scenarios. 'With vehicles taking up to three years to develop, [security strategist Brian Contos] says manufacturers will struggle to keep abreast of rapidly-evolving threats unless they organize regular software updates. Instead, he says, any installed technology should be given a so-called "white list" of permissible activities beyond which any procedures are blocked.' My mom reads CNN and is a Luddite. I expect to hear from her today. She'll probably tell me my new car with bluetooth is unsafe."

Ask Slashdot: What Is the Best Distro For Linux Lessons? 319

MBtronics writes "I work at an embedded hardware/software company and we are currently moving all our products for Windows CE to Linux. Our core development team already uses their favorite distro for development, but the rest of the developers are still working on Windows. We are going to give a series of Linux lessons (from 'what is Linux' to installing, using and developing) for everybody in the company who is interested (including non-developers). They will be allowed to choose their own distro, but we will certainly get requests for recommendations. My question to the Slashdot crowd: what distro (and window manager) do you think is the best to teach Linux to the generic public? We are currently thinking of Ubuntu, Fedora or Mint."

Sony To Delete Virtual Goods 171

New submitter dommer2029 writes "A few years back, Sony bought up a small company running an online collectible card game called Star Chamber: The Harbinger Saga. Two days ago, they announced that the servers will be shutting down on March 29, 2012. All of our virtual collectible cards? Poof. It's not surprising — the user base is small and dwindling — but it's proof that any server-based digital goods you 'own' can vanish on a corporation's whim."

In Theory And Practice, Why Internet-Based Voting Is a Bad Idea 218

A few countries, like Estonia, have gone for internet-based voting in national elections in a big way, and many others (like Ireland and Canada) have experimented with it. For Americans, with a presidential election approaching later this year, it's a timely issue: already, some states have come to allow at least certain forms of voting by internet. Proponents say online elections have compelling upsides, chief among them ease of participation. People who might not otherwise vote — in particular military personnel stationed abroad, but many others besides — are more and more reached by internet access. Online voting offers a way to keep the electoral process open to them. With online voting, too, there's no worry about conventional absentee ballots being lost or delayed in the postal system, either before reaching the voter or on the way back to be counted. The downsides, though, are daunting. According to RSA panelists David Jefferson and J. Alex Halderman, in fact, they're overwhelming. Speaking Thursday afternoon, the two laid out their case against e-voting.

Startup Wants To Peek Through Your Home's Wired Cameras 186

alphadogg writes "The little cameras in your home are multiplying. There are the ones you bought, perhaps your SLR or digital camera, but also those that just kind of show up in your current phone, your old phone, your laptop, your game console, and soon your TV and set-top box. Varun Arora, founder of startup GotoCamera in Singapore, wants you to turn them all on and let his company's algorithms analyze what they show, then sell the results as marketing data, in a sort of visual version of what Google and other firms do with search results and free email services."

Oxygen Found Around Saturn's Moon Dione 58

New submitter S810 writes "According to an article in Discovery News, oxygen was found by the Cassini spacecraft around Dione, one of Saturn's large moons. 'It is thought the oxygen is being produced via interactions between Saturn's powerful radiation belts and Dione's water ice. The radiation breaks the water molecules down, liberating oxygen into the moon's exosphere.' Hopefully this will open the door for more funding of research int the moons of Saturn and Jupiter."

Is Poor Numeracy Ruining Lives? 489

Hugh Pickens writes "The BBC reports on how millions of people struggle to understand a payslip or a train timetable, or pay a household bill. Government figures show that almost half the working population of England have only primary school math skills, and research suggests that weak math skills are linked with an array of poor life outcomes such as prison, unemployment, exclusion from school, poverty and long-term illness. 'We are paying for this in our science, technology and engineering industries but also in people's own ability to earn funds and manage their lives,' says Chris Humphries. He is the chairman of National Numeracy, an organization seeking to emulate the success of the National Literacy Trust, which has helped improve reading and writing standards since it was set up nearly 20 years ago. The Department for Education wants the vast majority of young people to study math up to 18 within a decade to meet the growing demand for employees with high level and intermediate math skills. 'It is simply inexcusable for anyone to say "I can't do maths,"' adds Humphries. "

Warp Drives May Come With a Killer Downside 458

An anonymous reader writes "Alcubierre warp-drives (theoretically) allow rocket ships to travel faster than the speed of light, while staying within the rules of Einstein's general theory of relativity. New research (PDF) has shown that as such warp-drives zip through the universe, they gather up particles and radiation, releasing them in a burst as the warp-drive slows down. This is bad news for family and friends waiting for the ship to arrive, as this intense burst will fry them."
