An anonymous reader writes "Hui Zhang and Shangui Zhao describe China's decision to move ahead with nuclear power. Following the Fukushima Daiichi accident, China slowed its rapid expansion of nuclear power and undertook a major reevaluation of safety practices. The government has now resumed approval of new nuclear power projects, and is cautiously moving forward. Good description of safety issues that remain." They are suspending in-land construction, and are aiming at 58GWe instead of 80GWe of generation capacity by 2020. It's still more than the 40GWe they planned to build under their 2007 plans.

An anonymous reader writes "In conjunction with its earnings report for the second quarter of 2013, Apple issued a press release announcing some major plans for its ever growing stockpile of cash. It is increasing its quarterly dividend payout to investors by 15%. What's more, the company will spend $60 billion in stock repurchases, making it in Apple's words, 'the largest single share repurchase authorization in history.'"

thecarchik writes "Most advocates and industry analysts expect lithium-ion batteries to dominate electric-car energy storage for the rest of this decade. But is Tesla Motors planning to add a new type of battery to increase the range of its electric cars? Tesla has filed for eight separate patents on uses of metal-air battery technology (for example, #20120041625). The metals covered for use in the metal-air battery are aluminum, iron, lithium, magnesium, vanadium, and zinc. Metal-air batteries, which slowly consume their anodes to give off energy, hit the news last month when Israeli startup Phinergy demonstrated its prototype battery and let reporters drive a test vehicle fitted with the energy-storage device. Mounted in a subcompact demonstration car, Phinergy's aluminum-air battery provides 1,000 miles of range, it said, and requires refills of distilled water (which acts as electrolyte in the cells) about every 200 miles."

littlesparkvt writes in with a bit from Space Industry News about Bigelow Aerospace's plans for the moon: "NASA and Bigelow Aerospace are in the initial planning phases for a moon base. 'As part of our broader commercial space strategy, NASA signed a Space Act Agreement with Bigelow Aerospace to foster ideas about how the private sector can contribute to future human missions,' Said David Weaver NASA Associate Administrator for the Office of Communications." Bigelow will be performing the study for free too. Robert Bigelow chatted with a radio host a few weeks ago about Bigelow's long-term space plans. They include refueling depots and a commercial moon base, since NASA isn't planning to go there.

First time accepted submitter IamIanB writes "Harvard Middle Eastern Studies student Todd Mostak's first tangle with big data didn't go well; trying to process and map 40 million geolocated tweets from the Arab Spring uprising took days. So while taking a database course across town at MIT, he developed a massively parallel database that uses GeForce Titan GPUs to do the data processing. The system sees 70x performance increases over CPU-based systems, and can out crunch a 1000 node MapReduce cluster, in some cases. All for around $5,000 worth of hardware. Mostak plans to release the system under an open source license; you can play with a data set of 125 million tweets hosted at Harvard's WorldMap and see the millisecond response time." I seem to recall a dedicated database query processor that worked by having a few hundred really small processors that was integrated with INGRES in the '80s.

mvar writes "Various sources report that a few days ago at CinemaCon Disney announced their plan to release, following the 2015 JJ Abrams Episode VII, a new Star Wars movie every 1 (one, uno, une) year. Yep, get your stomachs ready, because that's a lot of Jar Jar Binks."

An anonymous reader writes "For many of us our hosting providers are a way to hone our skills as well as run a business. Which provider out there gives the best bang for the buck for a FOSS developer? Virtually everybody provides Perl, PHP, Ruby, MySQL / MariaDB etc. but where can one get easy and cheap access to a stuff like NodeJS and Big Data? Companies such as Pair Networks are great but not quite on the mark with any of their service offerings for somebody looking to test out real world scenarios with these technologies from a hosted stance. Obviously hosting from home is always an option but that has the penalty of administration, backup, DR planning, bigger security footprint etc. and for those of us whose time is balanced between making money and friends / family time that's not very appealing."

cylonlover writes "Lockheed Martin has been getting its feet wet in the renewable energy game for some time. In the 1970s it helped build the world's first successful floating Ocean Thermal Energy Conversion (OTEC) system that generated net power, and in 2009 it was awarded a contract to develop an OTEC pilot plant in Hawaii. That project has apparently been canceled but the company has now shifted its OTEC sights westward by teaming up with Hong Kong-based Reignwood Group to co-develop a 10 MW pilot plant that will be built off the coast of southern China."

mikejuk writes "Java Development Kit 8, planned for September 2013, is being delayed until next year because of 'a renewed focus on security.' Java has been having security publicity problems recently, but Oracle now seems to be taking them more seriously. Mark Reinhold, chief architect of the Java platform group, said, 'Maintaining the security of the Java Platform always takes priority over developing new features, and so these efforts have inevitably taken engineers away from working on Java 8.' The major change still to be made to Java 8 is Project Lambda, which Reinhold says is 'the sole driving feature of the release.' He laid out alternatives, such as dropping Lambda from this release, but said Oracle has decided instead to wait until Lambda is ready. The revised schedule for JDK 8 has a developer preview scheduled for September, a release candidate scheduled for January 2014, and general availablity scheduled for March 2014. The delay means that Java SE 9 will probably be released in early 2016, rather than late 2015."

An anonymous reader writes with this good news from the Debian developers who have been working hard to release the next version of the distro: "We now have a target date of the weekend of 4th/5th May for the release. We have checked with core teams, and this seems to be acceptable for everyone. This means we are able to begin the final preparations for a release of Debian 7.0 — 'Wheezy'. The intention is only to lift the date if something really critical pops up that is not possible to handle as an errata, or if we end up technically unable to release that weekend (e.g. a required machine crashes or d-i explodes in a giant ball of fire). Every other RC fix that does not make it in time will be r1 material. Please be sure to contact us about the RC fixes you would like included in the point release!" Of particular interest to casual users, from the list of changes in 7.0: "Debian wheezy comes with full-featured libav (formerly ffmpeg) libraries and frontends, including e.g. mplayer, mencoder, vlc and transcode. Additional codec support is provided e.g. through lame for MP3 audio encoding, xvidcore for MPEG-4 ASP video encoding, x264 for H.264/MPEG-4 AVC video encoding, vo-aacenc for AAC audio encoding and opencore-amr and vo-amrwbenc for Adaptive Multi-Rate Narrowband and Wideband encoding and decoding, respectively. For most use cases, installation of packages from third-party repositories should not be necessary anymore. The times of crippled multimedia support in Debian are finally over!"

Famous for his work in math, astronomy, nuclear engineering, and theoretical physics, Freeman Dyson has left his mark on almost every scientific discipline. He's won countless awards, and written numerous books on a wide range of topics both scientific and philosophical. One of his biggest contributions to science was the unification of the three versions of quantum electrodynamics invented by Feynman, Schwinger and Tomonaga. 10 years after moving to the U.S. he started working on the Orion Project, which sought to create a spacecraft with a nuclear propulsion system. STNG exposed the idea of a Dyson sphere to the masses, and his hypothetical plan for making a comet habitable with the help of genetically-engineered plants is a personal favorite. Mr. Dyson has graciously agreed give us a bit of his time in order to answer your questions. As usual, ask as many as you'd like, but please, one question per post.

An anonymous reader writes "This evening's planned launch of the Orbital Sciences Antares rocket had to be canceled just 12 minutes before liftoff, due to the unexpected separation of the booster's umbilical cable while the vehicle was on the launch pad. This is the first attempt to fly the Antares rocket, which is a commercial craft and direct competitor to the SpaceX Dragon 9. Beyond being the first flight of a brand new commercial rocket, this mission is also notable for carrying three of NASA's PhoneSats; small satellites powered by Android running on Nexus smartphones. With each PhoneSat costing just $3,500, they're designed to test the limits of extremely low cost spacecraft, similar to the European STRaND-1 mission. Since this is simply an orbital test, and the Antares will not be attempting to dock with the International Space Station, the launch window is highly flexible. It's anticipated Orbital Sciences will make another attempt at launching the Antares within 48 hours."

antdude writes "BoingBoing reports on why it's 'so hard to make a phone call in emergency situations.' Quoting: '[The thing about] the radios is that they have different sizes of cells. You've got regular cells and then smaller sub-cells. You also have larger overlay macro-cells that are really big. They try to handle you within the small cell you're closest to. But it's a trade off between capacity — they'd like to have lots of small cells for that — and coverage — they don't want to put 100k small cells everywhere. So you might have a cell that covers a mile ara and then smaller cells within that that handle most of the traffic. ... In the end, it does come down to trade-offs. That's true of any network. You're interested in coverage first and then capacity. If you wanted to guarantee that a network never had an outage your capital investment would have to go up orders of magnitude beyond anything that is rational. So each network is trying to invest their budget in ways that make network appear to perform better. The cost of providing temporary extra capacity for the Boston Marathon, that's something that's in the budget and they plan for that event. But when you get something unexpected like a terrorist event, or an earthquake, or damage from a hurricane or tornado, then you have trade offs between capital and how robust your network is. Every time you have an event people say, "Oh, they didn't invest enough." But you look at New York City after Hurricane Sandy and Southern Manhattan was under 6 feet of water — all the buried infrastructure was lost.'"

hypnosec writes "Anonymous knocked the doors of Indiegogo in a bid to raise some crowd-sourced dough to expand its news coverage by establishing a dedicated site instead of tweets and tumblr blog posts and managed to raise 27 time as much money as initially targeted. The initial target was to raise $2000 to fund the site development work as well as pay for initial hosting. Anonymous is planning to host news, reports and blogs from independent online reporters under its, already in use, Your Anon News brand."

Lucas123 writes "In June, Harvard's Clean Energy Project plans to release to solar power developers a list of the top 20,000 organic compounds, any one of which could be used to make cheap, printable photovoltaic cells (PVCs). The CEP uses the computing resources of IBM's World Community Grid for the computational chemistry to find the best molecules for organic photovoltaics culled the list from about 7 million. About 6,000 computers are part of the project at any one time. If successful, the crowdsourcing-style project, which has been crunching data for the past two-plus years, could lead to PVCs that cost about as much as paint to cover a one-meter square wall." The big thing here is that they've discovered a lot of organic molecules that have the potential for 10% or better conversion; roughly equivalent to the current best PV material, and twice as efficient as other available organic PV materials.

The Kickstarter project we mentioned late last month to bring open source video editor OpenShot to Mac and Windows as well as its native base of Linux has surpassed its initial funding goal, and now is just shy (just under a thousand dollars shy, at this writing) of reaching all of the items on a revamped list of stretch goals. The only goal on that list not yet funded is a tantalizing one. JonOomph writes "The lead developer has proposed a revolutionary new feature, which would allow users to offload CPU, memory, and disk cache to a local server (or multiple local servers), dramatically increasing the speed of previewing and rendering. The more servers added to the pool, the faster the video editing engine becomes (with the primary limitation being network bandwidth). If the final goal of $40k is reached in the remaining hours, this feature will be added to the next version of OpenShot." Like all Kickstarter projects, though, there's no actual guarantee that things will come to pass as hoped; ya pays yer money, and ya takes yer chances. Update: 04/16 16:53 GMT by T : Some hours remain, but they've crossed the $40,000 line. I hope the funding is adequate to support the outlined plans.

FuzzNugget writes "In a recent blog post, Netflix details their plans to transition from Silverlight to HTML5, but with one caveat: HTML5 needs to include a built-in DRM scheme. With the W3C's proposed Encrypted Media Extensions, this may come to fruition. But what would we sacrificing in openness and the web as we know it? How will developers of open source browsers like Firefox respond to this?"

An anonymous reader writes with news that Microsoft may be working on a smartwatch. "The modern smartwatch market hardly even exists, and yet it's already starting to feel very crowded. Hot on the heels of plans (official and otherwise) from Apple and Samsung, the Wall Street Journal reports that Microsoft has also been shopping around for parts to build a 'watch-style device.' While details are scarce as to what that would entail, unnamed supplier executives tell the newspaper that Microsoft has been asking for 1.5-inch touchscreens. We wouldn't count on seeing an ultra-small Surface anytime soon, however -- these executives say they've visited Microsoft's campus, but they don't know whether the Windows developer is fully committed to its wrist-worn endeavor or just experimenting. If the project exists at all, of course. Still, there's finally a glimmer of hope for anyone who's still mourning the loss of their beloved SPOT watches."

coondoggie writes "In the process of detailing its $17.7 billion 2014 budget this week, NASA highlighted a mission to snag a 500-ton asteroid, bring it back, stash it near the moon and study it. It also took the time to put in a plug for an ongoing research project called Solar Electric Propulsion, which NASA says could be the key technology it needs to pull off the asteroid plan."

New submitter JonOomph writes "Director Alex Cox, the creator of Repo Man and Sid and Nancy, is making plans via Kickstarter for his next film, Bill, the Galactic Hero, a feature-length science fiction comedy set in the far reaches of our galaxy. He is challenging the norm by shooting the film on 35mm monochrome (black and white) film, possibly the last film to ever attempt this, and possibly the first feature film to be edited with popular open source video editor OpenShot." If you don't like spoilers, I suggest reading this short but fascinating piece on Repo Man (one of my all-time favorite movies) only after watching it.
