An anonymous reader writes: Bitcoin is getting smashed. The cryptocurrency was down 18% to about $892 per coin as of 8:17 a.m. ET on Thursday. It is the biggest drop in two years. Earlier this week, on its first trading day of the new year, Bitcoin crossed above the $1, 000 mark for the first time since 2013, but it has now tumbled below that level.

Bitcoin Is Crashing
Enlarge / Jeff Bezos, founder and Chief Executive of Amazon.com, in May, (credit: Alex Wong/Getty Images) We can say this much for Jeff Bezos, the founder of Amazon.com and Blue Origin—he does not lack ambition. First Bezos founded an online bookstore that became the largest retailer in the western world, and now he plans to self-fund a New Glenn rocket that is nearly as tall as the Saturn V launch vehicle and more than half as powerful. As wild as Bezos’ idea sounds, Blue Origin might be able to get the job done. And if Bezos and Blue Origin can fly their massive orbital rocket in the next three to four years, it would be a remarkable, unprecedented achievement in a number of ways that could radically remake spaceflight. Proof of concept First, a few words about why this might really be viable. It is true that all Blue Origin has flown so far is a propulsion module, powered by a single BE-3 engine, and a capsule on a suborbital flight. The company’s New Shepard spacecraft is designed to carry six passengers on 10- to 15-minute hops up to about 100km before bringing them back down to Earth. This is not dissimilar to the first Mercury flights in the early 1960s, hence the moniker New Shepard, named after pioneering astronaut Alan Shepard. Read 12 remaining paragraphs | Comments

Why Bezos’ rocket is unprecedented—and worth taking seriously
An anonymous reader quotes a report from Bloomberg: Apple Inc. invested $1 billion in Chinese ride-sharing service Didi, making one of its biggest bets on software and services and dealing a blow to Uber Technologies Inc.’s ambitions in the country. The iPhone maker will help Uber’s largest rival build up a ride-sharing platform that handles more than 11 million rides a day and serves about 300 million users across China, Didi said in a statement on Friday. Executive Officer Tim Cook has highlighted higher-margin services as a growth area and suggested he would use some of its $200 billion-plus cash hoard for investments. The investment in one of China’s largest online companies will allow Apple to forge alliances in its single largest market outside of the United States. Didi, incorporated as Xiaoju Kuaizhi Inc., is in the process of raising more than $2 billion at a valuation of about $25 billion, people familiar with the matter have said. It operates in 400 Chinese cities and works with more than 14 million Chinese car owners. The company is Uber’s most potent rival and has formed an international coalition with Lyft Inc. in the U.S., India’s Ola and Southeast Asia’s Grab to fight the globally expanding San Francisco firm. Apple is hoping to reinvigorate lackluster iPhone sales in China with its $1 billion investment in Didi. The last big investment the company made was when it acquired Beats for $3 billion in 2014.

Hyperloop One Here’s a look at the sled Hyperloop One is testing in North Las Vegas today. 4 more images in gallery In North Las Vegas today, a startup called Hyperloop One propelled a 10-foot-long sled down a track, accelerating it to 116 mph before it hit a patch of sand on the tracks. The test took about four seconds, USA Today reported . The test of Hyperloop One’s propulsion system is just one step of many on the path to achieve a dream put forth by Tesla and SpaceX CEO Elon Musk, who first drew up a plan to transport people at 760mph in low-pressure tubes in 2013. Musk decided not to pursue this business venture, which he called Hyperloop, but his whitepaper spawned two rival Hyperloop companies and an international student engineer competition . Hyperloop One, formerly known Hyperloop Technologies, announced its name change on Tuesday, hoping to differentiate itself from Hyperloop Transportation Technologies (HTT), which has also made considerable headway in research and development of such a transportation system. HTT announced on Monday that it had exclusively licensed passive magnetic levitation technology that would serve to keep Hyperloop pods off the track, minimizing friction as they speed through a tube.

New submitter insitus writes: On 10 December, Germany’s new Wendelstein 7-X stellarator was fired up for the first time, rounding off a construction effort that took nearly 2 decades and cost €1 billion. Initially and for the first couple of months, the reactor will be filled with helium—an unreactive gas—so that operators can make sure that they can control and heat the gas effectively. At the end of January, experiments will begin with hydrogen in an effort to show that fusing hydrogen isotopes can be a viable source of clean and virtually limitless energy.

New submitter club77er writes with a link to a DSL Reports article outlining some hefty subsidies (about $3 billion, all told) that CenturyLink has signed up to receive, in exchange for expanding its coverage to areas considered underserved: According to the CenturyLink announcement, the telco will take $500 million a year for six years from the Federal Communications Commission (FCC)’s Connect America Fund (CAF). In exchange, it will expand broadband to approximately 1.2 million rural households and businesses in 33 states. While the FCC now defines broadband as 25 Mbps down, these subsidies require that the deployed services be able to provide speeds of at least 10 Mbps down. Read more of this story at Slashdot.

HughPickens.com writes: The Bitcoin community is facing one of the most momentous decisions in its six-year history. The Bitcoin network is running out of spare capacity, and two increasingly divided camps disagree about what, if anything, to do about the problem. The technical issue is that a block, containing a record of recent transactions, currently has a 1MB limit. Increasing the block size would allow more transactions on the network at once, helping it to scale up to meet growing demand. But it would also make it more difficult for ordinary users to host full network “nodes” that validate new transactions on the network, potentially making the digital currency more centralized as a result. Now Rob Price writes that two high-profile developers have released a competing version of the codebase that risks splitting the digital currency in two. Gavin Andresen and Mike Hearn have released Bitcoin XT, an alternative version of the core software that supports increasing the block size when required. Bitcoin users will now be forced to decide between “Bitcoin Core” and Bitcoin XT, raising the prospect of a “fork, ” where the digital currency divides into two competing versions. According to Price, Core and XT are compatible right now. However, if XT is adopted by 75% of users by January 2016, it will upgrade to a larger block size that will be incompatible with Core — meaning that if the other 25% don’t then choose to convert, it will effectively split the currency into two. So far, 7.7% of the network has adopted XT, according to website XTnodes.com. “Ultimately, how the dispute is resolved may matter more than the specific decision that’s reached, ” says Timothy B. Lee. “If the community is ultimately able to reach a consensus, the process could become a template for resolving future disagreements. On the other hand, if disagreements fester for months — or, worse, if a controversial software change splits the Bitcoin network into two warring camps — it could do real damage to Bitcoin’s reputation.” Read more of this story at Slashdot.

Adding solar panels to your roof can be frustrating, since it’s often difficult to know if your home receives enough light to justify the investment. Google Maps, however, has satellite, navigation and sunlight data for every property in the world, so it’s ideally placed to tell you how many rays hit your crib on a daily basis. That’s why the firm is launching Sunroof, a database of how much solar energy hits each building in a city, helping people work out if it’s worth the effort. Sunroof is intended as a “treasure map” for future green energy projects , telling you how much of a saving you’d make and how long it’d take to make back your initial outlay. To begin with, Project Sunroof is only starting in a few places: Boston, San Francisco and Fresno, but if it’s successful, will roll out to the rest of the country, and the rest of the world, in the future. Once you’ve worked out how much you’re likely to generate in energy savings, the Sunroof website will put you in touch with a local installer. We tested the service out on Aol’s building in San Francisco, and it told us that it received 1, 841 hours of usable sunlight per year. The site was also able to tell us that we have roughly 15, 461 square feet of available space that we could use to install solar panels into that space. It then took us through our options, letting us know that we’d save $14, 000 if we leased the hardware from a third party, or $24, 000 if we bought them outright.
