In wake of Liberty Reserve bust, Mt. Gox will require user verification

On Thursday, the world’s largest Bitcoin exchange, Mt. Gox, announced that it would require all users to “be verified in order to perform any currency deposits and withdrawals. Bitcoin deposits do not need verification, and at this time we are not requiring verification for Bitcoin withdrawals.” The company did not provide any explanation about why it was imposing this new requirement, but it did say that it would be able to process most verifications within 48 hours. The move comes two days after federal prosecutors went after Liberty Reserve , another online currency that had notoriously poor verification. (In court documents, a federal investigator in that case included an address of “123 Fake Main Street, Completely Made Up City, New York” to create an account that was accepted.) It also comes two weeks after the Department of Homeland Security started investigating Mt. Gox over the possible crime of money transmitting without a license.

Printable A3-sized solar cells hit a new milestone in green energy

Victorian Organic Solar Cell Consortium Imagine a future where solar panels speed off the presses, like newspaper. Australian scientists have brought us one step closer to that reality. Researchers from the Victorian Organic Solar Cell Consortium (VICOSC) have developed a printer that can print 10 meters of flexible solar cells a minute. Unlike traditional silicon solar cells, printed solar cells are made using organic semi-conducting polymers, which can be dissolved in a solvent and used like an ink, allowing solar cells to be printed. Not only can the VICOSC machine print flexible A3 solar cells, the machine can print directly on to steel, opening up the possibility for solar cells to be embedded directly into building materials.

Tesla CEO says he’ll pay more to speed up LA freeway widening: “I’ve super had it”

Tesla CEO Elon Musk says that he would be willing to donate even more money as a way to accelerate the widening of a major north-south highway in Los Angeles, known as the 405 Freeway. So far, he’s already donated $50,000 out of a total cost that has now ballooned to $1.1 billion, but he said he’d gladly pay more to add more workers. “[I’d pay more] as a contribution to the city and my own happiness,” Musk told the Los Angeles Times on Thursday . “If it can actually make a difference, I would gladly contribute funds and ideas. I’ve super had it.” On Wednesday, the city received the dubious honor of having the worst traffic in the country , according to data company Inrix. Read 3 remaining paragraphs | Comments

Bitfloor, number four Bitcoin-based exchange, shuts down for good

On Wednesday evening, Bitfloor , the number four Bitcoin-based exchange (behind Mt. Gox, BTC-E, and Bitstamp) announced that it is closing its doors “indefinitely.” “Unfortunately, our US bank account is scheduled to be closed and we can no longer provide the same level of [US dollar] deposits and withdrawals as we have in the past,” wrote Roman Shtylman , the exchange’s founder. “As such, I have made the decision to halt operations and return all funds. Over the next days we will be working with all clients to ensure that everyone receives their funds. Please be patient as we process your request.” Ars reached out to Shtylman to find out more details, but he did not immediately respond. Read 2 remaining paragraphs | Comments

“Download this gun”: 3D-printed semi-automatic fires over 600 rounds

The white portion of this AR-15, known as the “lower,” was manufactured using 3D printing. Defense Distributed Cody Wilson, like many of his Texan forebears, is fast-talkin’ and fast-shootin’—but unlike his predecessors in the Lone Star State, he’s got 3D printing technology to further his agenda. Wilson’s non-profit organization, Defense Distributed , released a video this week showing a gun firing off over 600 rounds—illustrating what is likely to be the first wave of semi-automatic and automatic weapons produced by the additive manufacturing process. Last year, his group famously demonstrated that they could use a 3D-printed “lower” for an AR-15 semi-automatic rifle—but the gun failed after six rounds. Now, after some re-tooling, Defense Distributed has shown that it has fixed the design flaws and can seemingly fire for quite awhile. (The AR-15 is the civilian version of the military M16 rifle.)

Cellular data traffic keeps doubling every year

Florence Ion Worldwide mobile data traffic doubled over the past year and is expected to continue growing at a similar rate due to expanding smartphone sales and video traffic, telecom equipment maker Ericsson said in research released today. By the end of 2012, global data traffic on mobile networks (not including Wi-Fi) hit around 1,300 petabytes per month, twice as much as in the previous year, Ericsson said. Ericsson The chart shows an approximate doubling each year for the past few years. We’ve asked Ericsson for the raw data behind the report and will provide that if we get it. Ericsson’s measurements come from “a large base of commercial networks that together cover all regions of the world,” the report states. “They form a representative base for calculating world total traffic in mobile networks.” Read 10 remaining paragraphs | Comments

Sprint offers $2.1 billion to acquire the rest of Clearwire

As most observers expected , Sprint has finally made a formal offer to acquire the rest of Clearwire. On Thursday, Sprint said it would pay $2.1 billion for the remaining 49.7 percent of Clearwire that it does not currently control. As we reported yesterday , the move is widely seen as a play for Sprint to acquire Clearwire’s valuable 2.5 GHz spectrum, which it would use to offer LTE and strengthen its position against Verizon and AT&T. The bid works out to $2.90 per share—higher than the company’s closing price on Wednesday—but analysts say the offer may not be good enough. Read 2 remaining paragraphs | Comments

FreedomPop launches free home wireless to compete with low-end DSL

FreedomPop’s new Hub Burst will begin shipping in January 2013. FreedomPop Just over three months after launching its free portable hotspot , FreedomPop now says its ready for the second phase of its expansion plan—a free home wireless connection. Like its portable device, which requires an $89 deposit to get 500MB of free mobile data over WiMAX, this new device (also with an $89 deposit) will offer 1GB of free data in nearly all of the 80 largest urban markets across the United States. “You’ll get speeds of 9 to 12Mbps when it’s fully optimized,” FreedomPop’s CEO Stephen Stokols told Ars, saying that it would be comparable to DSL.

FCC and mobile carriers commit to nationwide text-to-911 by May 2014

It seems almost stupid that it’s nearly 2013 and we’re still unable to communicate with our emergency services in any way other than picking up the phone and calling them. We can certainly imagine situations where you’d want to be able to send a quick text message to local police. The US is a bit behind here—British mobile phone users have had access to EmergencySMS since 2009. For years, we’ve been covering the slow ascent of text-to-911 . But now, the Federal Communications Commission says that the nation’s Big Four mobile carriers have agreed to “accelerate” text-to-911 capabilities for debut in 2013, with a nationwide deployment by May 15, 2014. “Building on text-to-911 deployments and trials that are already underway, this agreement will accelerate progress and ensure that over 90 percent of the nation’s wireless consumers, including millions of consumers with hearing or speech disabilities, will be able to access emergency services by sending a text message to 911, where local 911 call centers (known as a Public Safety Answering Points, or PSAPs) are also prepared to receive the texts,” the FCC said in a statement Thursday.

AMD puts brakes on chip manufacturing as sales plummet

Windows 8 and the holidays have failed to give PC makers the usual yearly bump in sales, and now Advanced Micro Devices is paying the price. The company announced yesterday that it has reduced its chip manufacturing orders for the last three months of the company’s 2012 fiscal year by more than 75 percent, and it will pay a heavy penalty for the changes. In a new agreement signed with manufacturing partner GlobalFoundries , AMD reduced its promised silicon wafer purchases to just $115 million, down from $500 million, while agreeing to pay a $320 million penalty for the order change over the next year. AMD spun off GlobalFoundries in 2009, and in March of 2012 it sold off its remaining stake in the company , leaving an investment arm of the government of the United Arab Emirates as the company’s sole owner. The move is part of an emergency plan to keep AMD’s cash on hand up as revenues continue to slide. On a conference call yesterday, AMD interim Chief Financial Officer Devinder Kumar said, “Liquidity and cash management remain a key focus for AMD.” The chipmaker is still looking for a permanent CFO to fill the gap left by Thomas Seifert, who bailed on the company in September “to pursue other interests.” Read 4 remaining paragraphs | Comments
