The World of YouTube Bubble Sort Algorithm Dancing 68

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 160

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 118

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 60

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.

Submission + - South Korea Says Nuclear Reactors Safe After Cyberattacks (securityweek.com)

wiredmikey writes: South Korea on Thursday ruled out the possibility that recent cyber-attacks on nuclear power operator Korea Hydro and Nuclear Power Co (KHNP) could cause a malfunction at any of the country's 23 atomic reactors.

Earlier this week, South Korea heightened security in the wake of the leaks, with the defense ministry's cyber warfare unit increasing its watch-level against attacks from North Korean and other hackers. On Monday, KHNP launched a two-day drill, testing its ability to thwart a cyber attack.

According to Trend Micro, the malware used against KHNP was designed to wipe the master boot records (MBR) of compromised computers and is believed to have infected the targeted systems through a vulnerability in the Hangul Word Processor (HWP), a commonly-used application in South Korea.

Federal Judge: Facebook Must Face Suit For Scanning Messages 48

Rambo Tribble 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 61

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 32

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 34

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.
