MIT' Combines Carbon Foam and Graphite Flakes For Efficient Solar Steam Generati 110

Posted by timothy
from the science-fiction-future-awaits dept.
rtoz (2530056) writes Researchers at MIT have developed a new spongelike material structure which can use 85% of incoming solar energy for converting water into steam. This spongelike structure has a layer of graphite flakes and an underlying carbon foam. This structure has many small pores. It can float on the water, and it will act as an insulator for preventing heat from escaping to the underlying liquid. As sunlight hits the structure, it creates a hotspot in the graphite layer, generating a pressure gradient that draws water up through the carbon foam. As water seeps into the graphite layer, the heat concentrated in the graphite turns the water into steam. This structure works much like a sponge. It is a significant improvement over recent approaches to solar-powered steam generation. And, this setup loses very little heat in the process, and can produce steam at relatively low solar intensity. If scaled up, this setup will not require complex, costly systems to highly concentrate sunlight.

A Conversation with Ubuntu's Jono Bacon (Video) 53

from the the-world's-leading-death-metal-free-software-advocate dept.
You've probably heard Jono Bacon speak at a Linux or Open Source conference. Or maybe you've heard one of his podcasts or read something he's written in his job as Ubuntu's community manager or even, perhaps, read The Art of Community, which is Jono's well-regarded book about building online communities. Jono also wrote and performed the heavy metal version of Richard M. Stallman's infamous composition, The Free Software Song. An excerpt from the Jono version kicks off our interview, and the complete piece (about two minutes long) closes the video. Please note that this video is a casual talk with Jono Bacon, the person, rather than a talk with the "official" Ubuntu Jono Bacon. So please, pull up a chair, lean back, and join us.

savuporo writes "The Chang'e-3 lunar probe, which includes the Yutu or Jade Rabbit buggy, blasted off on board an enhanced Long March-3B carrier rocket from the Xichang Satellite Launch Center at 1:30 a.m. (12.30 p.m. EDT). Landing is expected on December 14, at a landing site called Sinus Iridium (the Bay of Rainbows), a relic of a huge crater 258 km in diameter. Coverage of the launch was carried live on CCTV, with youtube copies available."

Unlocked Firefox OS ZTE Open Is Now Available On eBay For For $80 122

SmartAboutThings writes "We've been hearing quite a lot lately about the Firefox OS, but there are actually only a few Firefox OS phones launched on the market. ZTE Open is one of them and is actually the first Firefox OS phone for consumers. Even if Firefox OS has support from carriers all over the world, it's pretty hard to sell devices in more locations across the world. To remedy that, ZTE is going to sell the Firefox OS Open phone on eBay for eighty dollars, which is actually ten dollars less than the launch price. A real great thing is that the handset will be off-contract and unlocked which means you will be able to use it on all mobile networks. ZTE didn't mention when exactly the device will go on sale on eBay, the company just mentioning 'soon.'"

Ask Slashdot: Moving From Contract Developers To Hiring One In-House? 524

from the wipe-his-brain-and-download-stack-overflow-into-it dept.
An anonymous reader writes "I run a small software consulting company who outsources most of its work to contractors. I market myself as being able to handle any technical project, but only really take the fun ones, then shop it around to developers who are interested. I write excellent product specs, provide bug tracking & source control and in general am a programming project manager with empathy for developers. I don't ask them to work weekends and I provide detailed, reproducible bug reports and I pay on time. The only 'rule' (if you can call it that) is: I do not pay for bugs. Developers can make more work for themselves by causing bugs, and with the specifications I write there is no excuse for not testing their code. Developers are always fine with it until we get toward the end of a project and the customer is complaining about bugs. Then all of a sudden I am asking my contractors to work for 'free' and they can make more money elsewhere. Ugh. Every project ends up being a battle, so, I think the solution is to finally hire someone full-time and pay for everything (bugs or not) and just keep them busy. But how can I make that transition? The guy I'd need to hire would have to know a lot of languages and be proficient in all of them. Plus, I can't afford to pay someone $100k/year right now. Ideas?"

Remote Desktop Backend Merged into Wayland 215

Posted by Unknown Lamer
from the thought-no-one-used-that-feature dept.
New submitter Skrapion writes "One month ago, an independent developer submitted patches to the Wayland's Weston compositor which adds support for FreeRDP, an open-source remote desktop protocol. Now, after six revisions, the remote desktop code has been merged into the trunk. While remote desktop has been prototyped in Weston once before by Wayland developer Kristian Høgsberg, this is the first time Wayland/Weston has officially supported the feature. For a summary of why we can expect Wayland's remote desktop to surpass X.Org's network transparency, see Daniel Stone's excellent talk from Linux.conf.au."

Boeing Touts Fighter Jet To Rival F-35 — At Half the Price 497

Posted by Soulskill
from the but-is-it-a-robot? dept.
An anonymous reader sends this news from the CBC: "In a dogfight of defense contractors, the hunter can quickly become the hunted. It's happening now to the F-35. The world's largest defense contractor, Lockheed Martin, is trying to convince wavering U.S. allies — including Canada — to stick with its high-tech, high-priced and unproven F-35 stealth fighter. But the F-35 is way behind schedule, way over budget and, now, it's grounded by a mysterious crack in a turbine fan. After years of technical problems, it's a tempting target for Lockheed Martin's rivals. It's no surprise, then, that the No. 2 defense contractor, Boeing, smells blood... The Super Hornet, it says, is a proven fighter while the F-35 is just a concept — and an expensive one at that. ... The Super Hornet currently sells for about $55 million U.S. apiece; the Pentagon expects the F-35 to cost twice as much — about $110 million."

MS Targets Google With Another Smear Campaign 513

from the you-can-trust-us dept.
walterbyrd writes with news that Microsoft's PR department has started a campaign to convince Gmail users that Google reads your personal emails, referring to Google's automated method of scanning emails for keywords to generate supposedly relevant advertising. "The gist of the scare campaign is that Google is a scary, scary company that reads your private emails in order to send you targeted ads. 'Even if you don't use Gmail, if you send email to someone who does, Google goes through those emails to generate advertising revenue too,' Microsoft warns in material sent to reporters. Oh, and Microsoft points out that six class-action lawsuits have been filed against Google over this issue, and asks people to sign a petition 'to tell Google to stop going through your personal email messages.'"

FBI Asked Megaupload To Preserve Pirated Files, Then Used Them Against Dotcom 241

avxo writes "According to an article on the New Zealand Herald, Kim Dotcom says his team has evidence showing that the Department of Homeland Security served a search warrant on Megaupload in 2010, forcing it to preserve pirated movies. According to Mr. Dotcom, those preserved movies are the center of the latest legal battle. 'When the FBI applied to seize the Megaupload site in 2012, it said the company had failed to delete pirated content and cited the earlier search warrant against the continued existence of 36 of the same 39 files.' He added: '[t]he FBI used the fact the files were still in the account of the ... user to get the warrant to seize our own domains. This is outrageous.'"

App Auto-Tweets False Piracy Accusations 231

Posted by Soulskill
from the i'm-spartacus dept.
An anonymous reader writes "Certain iPhone and iPad applications from a Japanese company have broken software piracy detection mechanisms that are sending out tweets on the user's own Twitter account, saying, 'How about we all stop using pirated iOS apps? I promise to stop. I really will. #softwarepirateconfession.' The trouble is, it's sending these out on accounts of users who actually paid up to $50 or more for the software and who are legally using it. The app is asking for access to users' Twitter accounts, but does not give the reason why it is asking, so the author of the article concluded (rightly) that things were being done deliberately. Would you want your legally purchased software to send out messages to all of your contacts on Twitter or on other social networks saying that you were a software pirate? Would you excuse the writers of the software if it was just an error in their piracy detection measures?"

Microsoft Makes Direct X 11.1 a Windows 8 Exclusive 553

Posted by Unknown Lamer
from the year-of-the-linux-desktop dept.
BluPhenix316 writes "Microsoft has made Direct X 11.1 a Windows 8 Exclusive. I think this is merely an update to make Direct X more integrated with Windows 8. Is this going to be the trend? To lock you into the OS updates so Windows 7 doesn't last as long as Windows XP has?" The update is pretty minor, but it does add Stereoscopic rendering, and there seemed to be an implication that no new DirectX updates after this will be made for Windows 7.

If I want your opinion, I'll ask you to fill out the necessary form.
