The World of YouTube Bubble Sort Algorithm Dancing 4

from the right-under-our-very-noses dept.
theodp writes In addition to The Ghost of Steve Jobs, The Codecracker, a remix of 'The Nutcracker' performed by Silicon Valley's all-girl Castilleja School during Computer Science Education Week earlier this month featured a Bubble Sort Dance. Bubble Sort dancing, it turns out, is more popular than one might imagine. Search YouTube, for example, and you'll find students from the University of Rochester to Osmania University dancing to sort algorithms. Are you a fan of Hungarian folk-dancing? Well there's a very professionally-done Bubble Sort Dance for you! Indeed, well-meaning CS teachers are pushing kids to Bubble Sort Dance to hits like Beauty and a Beat, Roar, Gentleman, Heartbeat, Under the Sea, as well as other music.

Xbox Live and PlayStation Networks Downed By Apparent Attack 43

mrspoonsi writes Both Xbox Live and PlayStation Network [were] down this morning, apparently due to a denial-of-service attack. The notorious hacking group Lizard Squad — which already carried out earlier attacks on Microsoft and Sony — has claimed responsibility on Twitter for these latest outages. While the group's role in all of this remains unconfirmed, it's worth noting that the group threatened last week to take down Xbox Live and PSN, according to Business Insider. And again, Lizard Squad has already proven it can successfully pull off such attacks, not to mention other malicious pranks.

Whatever the cause, the timing is obviously terrible: Plenty of people surely received one of the two consoles as Christmas presents today, while many more gamers would have happily spent the afternoon in front of the TV. In the meantime, both Sony and Microsoft have acknowledged the problem, with Sony issuing a tweet and Microsoft posting a message on its support website: "We're working to address this as quickly as we possibly can," reads its status website. "Thanks for your patience, Xbox members." In an email, a Microsoft spokesperson declined to comment further or say when the company expects to restore service. We've also asked Sony to comment and will update this post if and when it does.
The Xbox Live status page says service remains "limited," and the Playstation Network is listed as offline.

US Navy Sells 'Top Gun' Aircraft Carrier For One Penny 36

HughPickens.com writes Kitsap Sun reports at Military.com that the USS Ranger, a 1,050-foot-long, 56,000-ton Forrestal-class aircraft carrier, is being towed from the inactive ship maintenance facility at Puget Sound for a 3,400-mile, around-Cape Horn voyage to a Texas dismantler who acquired the Vietnam-era warship for a penny for scrap metal. "Under the contract, the company will be paid $0.01. The price reflects the net price proposed by International Shipbreaking, which considered the estimated proceeds from the sale of the scrap metal to be generated from dismantling," said officials for NAVSEA. "[One cent] is the lowest price the Navy could possibly have paid the contractor for towing and dismantling the ship."

The Ranger was commissioned Aug. 10, 1957, at Norfolk Naval Shipyard and decommissioned July 10, 1993, after more than 35 years of service. It was stricken from the Naval Vessel Register on March 8, 2004, and redesignated for donation. After eight years on donation hold, the USS Ranger Foundation was unable to raise the funds to convert the ship into a museum or to overcome the physical obstacles of transporting the ship up the Columbia River to Fairview, Oregon. As a result, the Ranger was removed from the list of ships available for donation and designated for dismantling. The Navy, which can't retain inactive ships indefinitely, can't donate a vessel unless the application fully meets the Navy's minimum requirements. The Ranger had been in pristine condition, but for a week in August volunteers from other naval museums were allowed to remove items to improve their ships. The Ranger was in a slew of movies and television shows, including "The Six Million Dollar Man," "Flight of the Intruder" and "Star Trek IV: The Voyage Home" where it stood in for the USS Enterprise carrier. But the Ranger's most famous role was in the 1980's Tom Cruise hit, "Top Gun." "We would have liked to have seen it become a museum, but it just wasn't in the cards," Navy spokesman Chris Johnson told Fox. "But unfortunately, it is a difficult proposition to raise funds. The group that was going to collect donations had a $35 million budget plan but was only able to raise $100,000."

Nokia's Back In the Tablet Business, With the Android Lollipop-Based N1 22

Esra Erimez writes It's been a little over a year since the announcement of Microsoft Corp.'s acquisition of Finnish tech veteran Nokia Oyj.'s Devices unit. A year later Chinese leaks site SINA Tech says Nokia is back and ready to compete against its former unit, suggesting it will launch in China on Jan. 7. As one commenter on the Daily Tech story points out (as does this ExtremeTech article from last month), the not-yet-launched N1, with its "one piece aluminum body, 7.9", 2048*1536, [and] 3:4 aspect ratio" looks an awful lot like the iPad mini, but costs quite a bit less.

Rambo Tribble (1273454) writes U.S. District Court Judge Phyllis Hamilton, on Tuesday, denied Facebook's bid to dismiss a class-action lawsuit against the social media giant, for violating users' privacy through the scanning of message content. In her rejection of Facebook's argument, the judge said the firm had, "...not offered a sufficient explanation of how the challenged practice falls within the ordinary course of its business."

How Target's Mobile App Uses Location Tech To Track You 46

Posted by timothy
from the bullseye-on-your-back dept.
An anonymous reader writes Big-box retailers are figuring out how to use mobile apps to drive in-store sales, but they're also concerned about privacy. To see how they're doing, Xconomy took Target's app for a spin on one of the busiest shopping days of the year. The app uses indoor location-mapping technology from a startup called Point Inside. The verdict? The app saved a few minutes in locating items around the store, but it would work better if it knew where shoppers (and the items on their lists) are at any time. With Apple's iBeacons set to roll out more widely, retail privacy will be a hot issue in 2015.

Inside China's 'Christmas Factory' Town, Yiwu 30

Posted by timothy
from the large-scale dept.
jones_supa writes China's manufacturing industry continues booming, which has led to the the town of Yiwu (a city of about 1.2m people in central Zhejiang province) being christened "China's Christmas village." The town has become the home of 600 factories that collectively churn out over 60% of all the world's Christmas decorations and accessories. The "elves" that staff these factories are mainly migrant labourers, working 12 hours a day for a maximum of £200 to £300 a month – and it turns out that all of them are not even entirely sure what Christmas is. Nevertheless, there are corridors lined with nothing but tinsel, streets throbbing with competing LED light shows, stockings of every size, plastic Christmas trees in blue and yellow and fluorescent pink, plastic pine cones in gold and silver. The complex of Yiwu International Trade Market was declared by the United Nations to be the "largest small commodity wholesale market in the world" and the scale of the operation necessitates a kind of urban plan, with this festival of commerce organised into five different districts, of which District Two is solely dedicated for Christmas stuff.

Startups: the Crazy Ones, the Misfits, the Rebels ... the Dumb 31

Posted by timothy
from the pets-dot-com dept.
An anonymous reader writes Many companies emerged in 2014 offering new ways to help people connect, get stuff done, or find that special someone. Slack, for example, offers a chatty alternative to work email. Or Yonomi might actually make an Internet connected home feasible. But other new startups, looking for that new and original thing, peddled products that were gimmicky, legally unsound, or just not super useful. On the other hand, sometimes things that seem gimmicky get revised down the road; Kozmo.com is my favorite example — the business model might not have been perfect, but the underlying idea wasn't so bad. Sometimes there's a large not-being-the-first-mover advantage.

North Korean Defector Spills Details On the Country's Elite Hacking Force 123

Posted by timothy
from the can't-hack-in-here-this-is-the-hacking-room dept.
mattydread23 writes Business Insider interviewed Jang Se-yul, a North Korean defector who trained in the country's Mirim University alongside some of the hackers who make up its elite Bureau 121 hacking squad. He explains how they train: 'They take six 90-minute classes every day, learning different coding languages and operating systems, from C to Linux. Jang says a lot of time was spent dissecting Microsoft programs, like the Windows operating system, and how to attack the overall computer IT systems of enemy countries like the U.S. or South Korea.' He also explains that these hackers are among the elite in North Korea, and even though they have unfiltered information about the outside world that their countrymen lack, most of them would never dream of leaving. (See also this story from earlier this month about the life of North Korea's elite hackers.)

DARPA Wants Help Building a Drone That Flies Like a Hawk 26

DillyTonto writes DARPA has put out a call for ideas on how to build a fast, autonomous, maneuverable UAV that can fly up to 45 mph, navigate without assistance from humans or GPS into and through buildings that are a labyrinth of stairwells, small rooms, narrow hallways and terrorists. DARPA wants this drone to fly like the bird in this awesome hawk POV video that shows it shooting through gaps narrow enough it has to tuck its wings to get through. If you can watch the video without thinking of the forest moon of Endor, there may be some movies you should watch over the holidays.

westlake writes Nature is reporting the discovery of mineralized rods and cones in a 300 million year old fossil fish found in Kansas. The soft tissues of the eye and brain decay rapidly after death, within 64 days and 11 days, respectively, and are almost never preserved in the fossil record — making this is the first discovery of fossil rods and cones in general and the first evidence for color vision in a fossilized vertebrate eye.

Russian Hackers Stole Millions From Banks, ATMs 46

Posted by timothy
from the where-the-money-is dept.
An anonymous reader writes Tens of millions of dollars, credit cards and intellectual property stolen by a new group of cyber criminals. Group-IB and Fox-IT, in a joint research effort, released a report about the Anunak hackers group. This group has been involved in targeted attacks and espionage since 2013. Anunak targets banks and payments systems in Russia and CIS countries. In Europe, USA and Latin America criminals were mainly focusing on retail networks as well as mass media resources. Anunak is unique in the fact that it aims to target banks and e-payment systems. The goal is to get into bank networks and gain access to secured payment systems. As a result, the money is stolen not from the customers, but from the bank itself. If they manage to infect governmental networks, they use the infrastructure for espionage.

App Gives You Free Ebooks of Your Paperbacks When You Take a "Shelfie" 119

from the show-us-the-pages dept.
Peter Hudson writes Alan Henry writes on LifeHacker: "Paper books are awesome, but sometimes there's no beating the portability of an ebook on your phone or tablet. If you have a physical book you'd love to read on the go, BitLit may be able to get you an ebook version for free—all you need to do is take a photo of your book case: a 'shelfie.'" CNET notes that it's not quite as useful as it sounds: "As you might expect from a startup in the e-book space, BitLit currently offers a very limited selection -- only about 75,000 books, so the likelihood of a match is pretty slim. Browsing the library, I recognized very few mainstream authors."

Samsung Galaxy Note Edge Review 66

Posted by samzenpus
from the check-it-out dept.
MojoKid writes Differentiation is difficult in the smartphone market these days. Larger screens, faster processors, additional sensors and higher resolution cameras, all are nice upgrades but are only iterative, especially when you consider the deluge of products that come to market. True innovation is coming along with less frequency and Samsung, more so perhaps than some other players, is guilty of punching out so many different phone models that it's hard not to gloss over new releases. However, the new Samsung Galaxy Note Edge may offer something truly useful and innovative with its supplementary 160 pixel curved edge display. The Note Edge is based on the same internal platform as the Galaxy Note 4, and features a 2.7GHz Qualcomm Snapdragon 805 SoC with Adreno 420 graphics and 3GB of RAM. What makes the Galaxy Note Edge so different from virtually all other smartphones on the market is its curved edge display and what Samsung calls its "revolving UI" that offers app shortcuts, status updates, data feeds and features all on its own, but integrated with the rest of the UI on the primary display. You can cycle through various "edge panels" as Samsung calls them, like shortcuts to your favorite apps, a Twitter ticker, news feeds, and a tools panel for quick access to the alarm clock, stop-watch, a flashlight app, audio recorder and even a digital ruler. The Galaxy Note Edge may not be for everyone, but Samsung actually took curved display technology and built something useful out of it."
