UK Researchers Build Micron LED Light Based Wireless Network 70 70

Mark.JUK writes "Scientists working at the University of Strathclyde in Scotland (United Kingdom) have begun to develop a new Light Fidelity (Li-Fi) technology that will use special micron-sized LED (Light-Emitting Diodes) lights, such as those that could be used as part of home lighting or TV displays, to form part of a sophisticated wireless communications network (much like Wi-Fi is today). The principle, which revolves around manipulating the on/off flicker of LED lights to produce a digital network (a bit like Morse Code from a torch), is not new but most of the other teams are focusing on larger Li-Fi LEDs of around 1mm square in size. However micron sized LEDs not only allow you to use more lights (each of which can act as a separate data channel) but they can also flicker on and off around 1,000 times quicker than the larger LEDs."

Ask Slashdot: Name Conflicts In Automatically Generated Email Addresses? 383 383

New submitter matteocorti writes "I work at medium-sized university and we are considering reducing the number of domains used for email addresses (now around 350): the goal is to have all the 30K personal addresses in a single domain. This will increase the clashes for the local part of the address for people with the same first and last name (1.6%). We are considering several options: one of them is to use 'username@domain.tld' and the other is to use 'first.last@domain.tld.' The first case will avoid any conflict in the addresses (usernames are unique) but the second is fancier. Which approach does your organization use? How are name conflicts (homonyms) solved? Manually or automatically (e.g., by adding a number)?"

Yes, PlayBook Does Get BlackBerry 10 Update 90 90

judgecorp writes "Yesterday's BlackBerry 10 announcement did not mention the company's tablet, the Playbook, but users will be relieved to know it will get an update to BlackBerry 10. It's not a huge surprise, since BB10 is based on the PlayBook's QNX operating system, but PlayBook users may have been worried since the company did not even mention the struggling tablet in passing at the event." Hopefully the Playbook's camera is better than the one in the new BB10-based Z10 phone, the low-light performance of which Gizmodo describes as "four-years-ago crap."

Time Warner Boosts Broadband Customer Speed — But Only Near Google Fiber 203 203

An anonymous reader writes " Rob is a Time Warner Cable customer, and he's received two really interesting things from them lately. First, a 50% speed boost: they claim to have upgraded the speed of his home Internet connection. That's neat. Oh, and they've also cut his bill, from $45 to $30. Wow! What has prompted this amazing treatment? Years of loyalty and on-time payments? No, not exactly. Rob lives in Kansas City, pilot site for Google Fiber. Even though they have shut off people in other states for using too much bandwidth. Is Google making them show that it's not that hard to provide good service and bandwidth?"

"Bill Shocker" Malware Controls 620,000 Android Phones In China 138 138

Orome1 writes "A new discovered malware is potentially one of the most costly viruses yet discovered. Uncovered by NQ Mobile, the 'Bill Shocker' (a.expense.Extension.a) virus has already impacted 620,000 users in China and poses a threat to unprotected Android devices worldwide. Bill Shocker downloads in the background, without arousing the mobile device owner's suspicion. The infection can then take remote control of the device, including the contact list, Internet connections and dialing and texting functions. Once the malware has turned the phone into a "zombie," the infection uses the device to send text message to the profit of advertisers. In many cases, the threat will overrun the user's bundling quota, which subjects the user to additional charges."

Chinese Hack New York Times 116 116

Rick Zeman writes "According to a headline article in the New York Times, they admit to being hacked by the Chinese, and covers the efforts of Mandiant to investigate, and then to eradicate their custom Advanced Persistent Threats (APT). This was alleged to be in reaction to an article which details the sleazy business dealings of the family of Wen Jiabao, China's newest Prime Minister. China's Ministry of National Defense said in denial, 'Chinese laws prohibit any action including hacking that damages Internet security.'" Update: 01/31 15:00 GMT by T : The Times used Symanetic's suite of malware protection software; Symantec has issued a statement that could be taken as slightly snippy about its role in (not) preventing the spyware from taking hold.

Man Fired For His Online Customer Service Game 210 210

First time accepted submitter DiscountBorg(TM) writes "An employee of the Canada Revenue Agency lost his job after releasing a humorous game in which the player answers customer service calls for the Agency, usually leading to his termination. In an email National Revenue Minister Gail Shea said: 'The Minister considers this type of conduct offensive and completely unacceptable. The Minister has asked the Commissioner (of Revenue, Andrew Treusch) to investigate and take any and all necessary corrective action. The Minister has asked the CRA to investigate urgently to ensure no confidential taxpayer information was compromised.'"

Real-Time Fact Checking With "Truth Teller" 149 149

The Washington Post has announced a prototype news application called "Truth Teller", that displays “TRUE" or “FALSE” in real time next to video of politicians as they speak. The Knight Foundation-funded program automatically transcribes speeches and checks the statements against a database of facts. From the article: "For now, the early beta prototype has to be manually hand-fed some facts, and thus only works on topics it has been specifically designed to recognize. Since Congress has yet to pass a budget, and financial discussions are prone to widespread lies and misstatements, Truth Teller is being piloted on the issue of tax policy."

NASA Says Asteroid Will Buzz Earth Closer Than Many Satellites 225 225

coondoggie writes "NASA says an asteroid about half the size of a football field will blow past Earth on Feb 15 closer than many man-made satellites. NASA added that while the asteroid, designated 2012 DA14, has no chance of striking Earth. Since regular sky surveys began in the 1990s, astronomers have never seen an object so big come so close to our planet."

What You Can Do About the Phone Unlocking Fiasco 416 416

itwbennett writes "Now that the ridiculous phone unlocking law is a done deal, and we all understand exactly what that means (i.e., 'fines of up to $500,000 and imprisonment of up to five years'), you might be left wondering what can you do about it. Well, you could start by lending your John Hancock to this petition at the White House's 'We The People' platform. It's already over halfway to the number of signatures required to get a response from the executive branch."

Silicon Valley Before the Startup 57 57

kenekaplan writes "An upcoming PBS documentary reveals how technology pioneers transformed Silicon Valley into the epicenter of technology innovation. From the article: 'Gordon Moore remembers a time before the idea of a Silicon Valley startup existed. That was half a century ago, before the place became an epicenter for wildly successful technology, and companies such as Apple, Google and Intel generated billions of dollars in annual profits. “It just exploded,” said Moore in the PBS documentary, “American Experience: Silicon Valley,” premiering Feb. 5. “Every time we came up with a new idea we spawned two or three companies that would try to exploit it,” he said, referring to his days at Fairchild Semiconductor, a company he helped found in 1957, a decade before he co-founded Intel with Robert Noyce.'"

Microsoft Embraces Git For Development Tools 227 227

alphadogg writes "Once vehemently opposed to open-source software, Microsoft has warmed to the development model over the years and will now take the unusual step of incorporating an open-source program developed by Linus Torvalds into its own development tools. Microsoft is integrating the widely used Git, a distributed revision control and source code management system, into its Visual Studio IDE and Team Foundation Server, two of the company's main tools for enterprise developers."

Walk or Run: Are We Built To Be Lazy? 189 189

sciencehabit writes "A quick visit to Monty Python's Ministry of Silly Walks shows just how many ways humans (or at least British comedians) can think of to travel from point A to point B. So why don't we high kick our way to the bus stop or skip to the grocery store? New research suggests that there may be a deep biomechanical reason governing the gaits we choose in different situations. In short, people consistently choose to walk when they need to travel slower than 2 m/s to reach their goal in the given time; when they needed to move about 3 m/s or faster, they ran. But in between—in 'the twilight zone between walking and running'—people tended to mix the two gaits, minimizing their energy expenditure. The findings could help scientists design better prosthetic limbs and even build more human-like robots"

DMVs Across the Country Learning Textspeak 178 178

First time accepted submitter 3seas writes in about DMVs across the country learning textspeak in order to keep vulgar acronyms off the road. "You can have txtspeak on your plate in Arizona, but only if you keep it clean. 'ROFLMAO' is a no-go. Arkansas, however, seems to be a little slower on the uptake. 'ROFLMAO' doesn't appear on the state's prohibited list. That doesn't necessarily mean the plate would pass DMV scrutiny should someone request it."
