Researchers Create Origami Wheels That Can Change Size

Slashdot - 21 hours 55 min ago
rtoz writes Researchers from Seoul National University have designed a robotic wheel based on the origami "magic ball pattern," which is a traditional technique used to create folded paper spheres. This robotic wheel can change its radius to create larger wheels to climb over things, and shrink back to a smaller size to squeeze under obstacles. The diameter of the wheels changes automatically to enable the robot to either be strong or speedy. The scientists think their innovation could one day be used for interplanetary rovers as the wheel can be folded up and "inflate" itself.

The Almost Forgotten Story of the Amiga 2000

Slashdot - Sun, 07/20/2014 - 11:04pm
polyp2000 writes Many don't realize the impact the much forgotten Amiga 2000 had on the world. This lovely article is an informative and lighthearted read, especially if you are interested in the world of CG. "Unfortunately, The Amiga 2000 is one of the least favorite or collectible Amigas. Even today, with the most "die hard" Amiga fans, the A2000 often is ignored and shunned as a 'big, ugly' tank of a machine. One look at eBay (Canada or the U.S.), on any given day, and you can see that the A2000 often doesn't sell at all, and most times goes for a lot cheaper than all the other Amigas — even cheaper than an A500. But, because of this, one can find awesome deals, because, most of the time, the seller has no clue about what Zorro cards are inside, and for next to nothing, you can pick up a fully loaded A2000 with an '030 or above for peanuts."

A Look At NASA's Orion Project

Slashdot - Sun, 07/20/2014 - 8:02pm
An anonymous reader writes "People in north Iowa got a first-hand look at NASA's Orion Project. Contractors with NASA were in Forest City to talk about the new project and show off a model of the new spaceship. NASA has big plans to send humans to an asteroid by 2025. The mission, however, will not be possible without several important components that include yet-to-be-developed technologies, as well as the Space Launch System (SLS) and the Orion spacecraft to fly astronauts beyond low-Earth orbit. In fact, Orion's first flight test later this year will provide NASA with vital data that will be used to design future missions."

Russian Government Edits Wikipedia On Flight MH17

Slashdot - Sun, 07/20/2014 - 6:50pm
An anonymous reader writes A political battle has broken out on Wikipedia over an entry relating to the crash of Malaysian Airlines flight MH17, with the Russian government reportedly removing sections which accuse it of providing 'terrorists' with missiles that were used to down the civilian airliner. A Twitter bot which monitors edits made to the online encyclopedia from Russian government IP addresses spotted that changes are being made to a page relating to the crash. All-Russia State Television and Radio Broadcasting Company (VGTRK) changed a Russian language version of a page listing civil aviation accidents to say that "The plane was shot down by Ukrainian soldiers." That edit replaced text – written just an hour earlier – which said MH17 had been shot down "by terrorists of the self-proclaimed Donetsk People's Republic with Buk system missiles, which the terrorists received from the Russian Federation."

Ars Editor Learns Feds Have His Old IP Addresses, Full Credit Card Numbers

Slashdot - Sun, 07/20/2014 - 5:38pm
mpicpp writes with the ultimate results of Ars's senior business editor Cyrus Farivar's FOIA request. In May 2014, I reported on my efforts to learn what the feds know about me whenever I enter and exit the country. In particular, I wanted my Passenger Name Records (PNR), data created by airlines, hotels, and cruise ships whenever travel is booked. But instead of providing what I had requested, the United States Customs and Border Protection (CBP) turned over only basic information about my travel going back to 1994. So I appealed—and without explanation, the government recently turned over the actual PNRs I had requested the first time. The 76 new pages of data, covering 2005 through 2013, show that CBP retains massive amounts of data on us when we travel internationally. My own PNRs include not just every mailing address, e-mail, and phone number I've ever used; some of them also contain: The IP address that I used to buy the ticket, my credit card number (in full), the language I used, and notes on my phone calls to airlines, even for something as minor as a seat change.

High School Students Not Waiting For Schools To Go Online

Slashdot - Sun, 07/20/2014 - 4:27pm
lpress writes UCLA conducts an annual survey of first-time, full-time college freshman and this year they included questions about the use of online education sites like Coursera and The Khan Academy. It turns out that over 40 percent of the incoming freshmen were frequently or occasionally assigned to use an online instructional website during the past year and nearly 70 percent had used online sites on their own. Students enrolling in historically black colleges were much more likely than others to have used online teaching material. They also compile a "habits of mind" index, and conclude that "Students who chose to independently use online instructional websites are also more likely to exhibit behaviors and traits associated with academic success and lifelong learning." The survey covers many other characteristics of incoming freshmen — you can download the full report here

Critroni Crypto Ransomware Seen Using Tor for Command and Control

Slashdot - Sun, 07/20/2014 - 3:19pm
Trailrunner7 writes There's a new kid on the crypto ransomware block, known as Critroni, that's been sold in underground forums for the last month or so and is now being dropped by the Angler exploit kit. The ransomware includes a number of unusual features and researchers say it's the first crypto ransomware seen using the Tor network for command and control. The Critroni ransomware is selling for around $3,000 and researchers say it is now being used by a range of attackers, some of whom are using the Angler exploit kit to drop a spambot on victims' machines. The spambot then downloads a couple of other payloads, including Critroni. Once on a victim's PC, Critroni encrypts a variety of files, including photos and documents, and then displays a dialogue box that informs the user of the infection and demands a payment in Bitcoins in order to decrypt the files. "It uses C2 hidden in the Tor network. Previously we haven't seen cryptomalware having C2 in Tor. Only banking trojans," said Fedor Sinitsyn, senior malware analyst at Kaspersky Lab, who has been researching this threat. "Executable code for establishing Tor connection is embedded in the malware's body. Previously the malware of this type, this was usually accomplished with a Tor.exe file. Embedding Tor functions in the malware's body is a more difficult task from the programming point of view, but it has some profits, because it helps to avoid detection, and it is more efficient in general."

Exhibit On Real Johnny Appleseed To Hit the Road

Slashdot - Sun, 07/20/2014 - 2:10pm
An anonymous reader writes with this story about a traveling Johnny Appleseed exhibit set to hit the road sometime next year. If you picture Johnny Appleseed as a loner wearing a tin pot for a hat and flinging apple seeds across the countryside, experts say you're wrong. They're hoping that a traveling exhibit funded by an anonymous donation to a western Ohio center and museum will help clear misconceptions about the folk hero and the real man behind the legend. "We want people around the country to know the real person, not just the myths and folklore," said Cheryl Ogden, director of the Johnny Appleseed Educational Center and Museum at Urbana University in Urbana. "We want them to know John Chapman's values of hard work, compassion and generosity." Chapman, known as Johnny Appleseed to generations of Americans, was a pioneer nurseryman in the late 18th and early 19th centuries credited with introducing apple trees to portions of Ohio, Indiana, Illinois, Pennsylvania, Kentucky and West Virginia. While it's probably true that he lived outdoors and wore ragged clothes, at least sometimes, researchers doubt he wore a pot on his head or just gave his seedlings and nurseries away.

"Intelligent" Avatars Poised To Manage Airline Check-In

Slashdot - Sun, 07/20/2014 - 11:53am
An anonymous reader writes One of the developers behind special effects used in the film Avatar has inked a deal with airline check-in kiosk manufacturer BCS to implement avatars for personalized and interactive customer service. Dr Mark Sagar's Limbic IO is applying 'neurobehavioral animation' combining biologically based models of faces and neural systems to create live, naturally intelligent, and expressive interactive systems. "One of the comments levelled at self-service check in is that it has lost the human touch that people had when checking in at a traditional manned counter," Patrick Teo, BCS CEO says. "Travelling can be stressful and our aim is to make the interaction between human (passenger) and computer (check-in) as natural and helpful as possible."

Apollo 11 Moon Landing Turns 45

Slashdot - Sun, 07/20/2014 - 10:46am
An anonymous reader writes On July 20, 1969, U.S. astronauts Neil Armstrong and Buzz Aldrin became the first humans to walk on the moon. Neil Armstrong would say later he thought the crew had a 90% chance of getting home from the moon, and only a 50% chance of landing safely. The scope of NASA's Apollo program seems staggering today. President Kennedy announced his moon goal just four years into the Space Age, but the United States had not even launched a human into orbit yet. Amazingly, just eight years later, Armstrong and Aldrin were walking on the moon.

MicroxWin Creates Linux Distribution That Runs Debian/Ubuntu & Android Apps

Slashdot - Sun, 07/20/2014 - 9:39am
An anonymous reader writes VolksPC who developed MicroXwin as a lightweight X Window Server has come up with their own Linux distribution. Setting apart VolksPC's distribution from others is that it's based on both Debian and Android and has the capability to run Debian/Ubuntu/Android apps together in a native ARM experience. The implementation doesn't depend on VNC or other similar solutions of the past that have tried to join desktop apps with mobile Android apps. This distribution is also reportedly compatible with all Android applications. The distribution is expected to begin shipping on an ARM mini-PC stick.

States That Raised Minimum Wage See No Slow-Down In Job Growth

Slashdot - Sun, 07/20/2014 - 8:30am
An anonymous reader writes: The U.S. Department of Labor has released data that some proponents of raising minimum wage are touting as evidence that higher minimum wage promotes job growth. While the data doesn't actually establish cause and effect, it does "run counter to a Congressional Budget Office report in February that said raising the minimum wage to $10.10 an hour, as the White House supports, would cost 500,000 jobs." The data shows that the 13 states that raised their minimum wages in January added jobs at a faster rate than those that didn't. Other factors likely contributed to this outcome, but some economists are simply relieved that the higher wage factor didn't have a dramatically negative effect in general.

Can the Multiverse Be Tested Scientifically?

Slashdot - Sun, 07/20/2014 - 5:27am
astroengine writes: Physicists aren't afraid of thinking big, but what happens when you think too big? This philosophical question overlaps with real physics when hypothesizing what lies beyond the boundary of our observable universe. The problem with trying to apply science to something that may or may not exist beyond our physical realm is that it gets a little foggy as to how we could scientifically test it. A leading hypothesis to come from cosmic inflation theory and advanced theoretical studies — centering around the superstring hypothesis — is that of the "multiverse," an idea that scientists have had a hard time in testing. But now, scientists at the Perimeter Institute for Theoretical Physics, in Ontario, Canada have, for the first time, created a computer model of colliding universes in the multiverse in an attempt to seek out observational evidence of its existence.
