After his amateur rocket flight in the desert (to 121,000 feet!), you asked rocket enthusiast Derek Deville about the project. Derek's responded to a selection of the best of those questions; read on below for his replies.

First time accepted submitter A12m0v writes with a link to Fujitsu's announcement of its next generation of supercomputer, from which he pastes: "PRIMEHPC FX10 runs on the newly-developed SPARC64 IXfx processors, which offer a very significant boost in performance over the SPARC64 VIIIfx processor on which they are based and which power the K computer. Each processor has 16 cores and achieves world-class standalone performance levels of 236.5 gigaflops and performance per watt of over 2 gigaflops." Not that K is any slouch.

schliz writes "Alcatel-Lucent's research arm, Bell Labs, is building low-cost robots that represent remote participants in meeting rooms. Researchers hope it will address the issue of the natural, non-verbal 'voting mechanism,' by which people determine who should speak based on who most people are looking at. The technology will likely be priced in the 'hundreds of dollars,' rather than the tens of thousands that the likes of Cisco and Polycom charge for high-end telepresence rooms."

First time accepted submitter Gortu writes "We are describing and demonstrating a 3D Volumetric Projector (YouTube video); in short words: a device that enables mixed reality. The 3D projector has very poor quality, we just have 10 rotational voxels (as we are using only 10 regular LCD projectors), but is proof of concept for developing a commercial solution."

An anonymous reader writes "The GNOME 3.0 Shell with the Mutter window manager no longer requires GPU acceleration to work, while still retaining the compositing window manager and OpenGL support. GNOME Shell can now work entirely on the CPU using the LLVM compiler via the Gallium3D LLVMpipe driver. This will be another change to Fedora 17 to no longer depend upon the GNOME3 fall-back, which is expected to eventually be deprecated and further anger GNOME2 fans."

deadeyefred writes "Dropbox last month launched its Teams service, targeted at small and mid-sized businesses — but acknowledges it's not PCI-, HIPAA- or Sarbanes-Oxley compliant. Company executives say they also don't provide a highly visible warning largely because customers in beta tests didn't make it an issue. Should cloud services focused at businesses provide clear warnings if they are not compliant with key regulatory requirements, or should business customers just assume they are not?"

Lord Byron II writes "My grandma is in her 80s, is bed-ridden, in a nursing home, and is basically reaching the end of her life. Her legs are weak, meaning that she is confined to her bed, and her hearing is pretty much gone. Her sight is good and her mental facilities are still there, but even so, she spends most of her days just watching daytime TV, like the Price is Right and talk shows. The family has tasked me with finding her an easy-to-use, not overly expensive device that would mentally challenge her. Ideally, I would like to get something iPad like so that she could play card games and such. But the Internet connectivity and advanced features are completely unnecessary. Is there a simple device that will let her easily play some games?"

DeviceGuru writes with this excerpt: "Barnes & Noble is expected to announce a 7-inch color tablet on November 7th, positioning it head-to-head with Amazon's recently announced Kindle Fire. B&N's Nook Tablet is rumored to have a slightly faster processor, twice the RAM and flash, and a $50 price premium relative to Amazon's tablet, among other differences. The quick-reference table in this article compares key features and specs of the two 7-inch Android tablets, based on a combination of leaked data published at Engadget.com plus some additional data from B&N's existing Nook Color specs, which seems to have much in common with this new, higher-end Nook model."

hazytodd writes "Repairs to Android smartphones cost wireless carriers $2 billion per year according to a new year-long WDS study that tracked 600,000 support calls around the globe. Android's popularity and the introduction of a number of low-cost smartphones has put a strain on the wireless business model, WDS noted in its report. 'Deployment by more than 25 OEMs and lower-cost product coming to market is leading to higher than average rates of hardware failures and, in turn, return and repair costs.'"

pmontra writes "A Spanish company has won a legal case against Apple and will be able to sell an Android tablet that Apple had claimed infringes on the iPad patent. It is now seeking damages from Apple for a temporary seizure of its products by Spanish customs. Furthermore they are pursuing an antitrust complaint against Apple, alleging abusive anticompetitive behavior."

bdking writes "After more than two weeks of complaints from frustrated iPhone 4S owners, Apple finally has admitted problems with fast-draining batteries in the new devices. The company blames it on bugs in iOS 5 and promises a fix 'in a few weeks.' But Apple should have spoken up sooner, if only to acknowledge the issue."

Kyusaku Natsume writes "Tokyo Electric Power Co. said Wednesday that some of the melted fuel in reactor 2 at the Fukushima No. 1 nuclear plant may have triggered a brief criticality event. Tsuyoshi Misawa, a reactor physics and engineering professor at Kyoto University's Research Reactor Institute, said that if Tepco's data are correct, 'it's clear that the detection (of xenon-133 and -135) comes from nuclear fission.' Tepco spokesman Junichi Matsumoto said the test results suggest that either small-scale fission occurred in the melted fuel, or conditions to trigger criticality were temporarily met for some other reason. He said the same thing could also happen at reactors 1 and 3. But because the reactor's temperature and pressure level have not changed, the fission would not have been large-scale, Matsumoto said, adding that it would not thwart Tepco's schedule for achieving a cold shutdown at the reactors. In response, boric acid water was injected again on November 2. On the plus side, the concentration of radioactive materials in the air is low enough that workers inside some areas of Fukushima Daiichi workers soon will not have to use full face masks."

Tasha26 writes "A trainee surgeon, Mark Frame, has figured out how to save U.K.'s NHS thousands of pounds by taking advantage of 3D-printer technology. Success in orthopedic operations relies on surgeons having an accurate 3D model of the area where the operation will take place. Such models take time to produce and cost up to £1200 ($1915). Mark, a self-confessed 'technology geek,' used open source OsiriX software to convert CT scans into files which are readable by the 3D printers at Shapeways, a company in the Netherlands. Within a week they produced and delivered the first plastic 3D model of a child's forearm at a cost of £77 ($123). Mark has written a free guide so that other surgeons can make their own bones, which is being considered for publication by the World Journal of Science and Technology."

Stirling Newberry writes "Non-conventional extraction of hydrocarbons is the next wave of production, including natural gas and oil – at least according to its advocates. One of the most controversial of the technologies being used is hydraulic fracture drilling, or 'fracking.' Energy companies have been gobbling up Google ad words to push the view that the technology is 'proven' and 'safe,' while stories about the damage continue to surface. Adding to the debate are two small tremors in the UK — below 3.0, so very small – that were quite likely the result of fracking there. Because the drilling cracks were shallow, this raises concerns that deeper cracks near more geologically active areas might lead to quakes that could cause serious damage."

sl4shd0rk writes "Nicholas Negroponte and the OLPC project are still going and have a new plan in the works: a laptop air-drop to help facilitate 'self-education' in areas with large poor populations. 'In the first year we'll go in and meet with tribal elders and aid organizations, people not involved with education, but then we let the kids learn,' Negroponte said. All of this work by Negroponte and others was essential, he explained, because market forces were leaving the poor of the world behind. Meanwhile, the largest countries had adopted strategies that offer little for the developing world."

Hugh Pickens writes "Gary Morgenthaler, a recognized expert in artificial intelligence and a Siri board member, says that Apple now has at least a two-year advantage over Google in the war for best smartphone platform. 'What Siri has done is changed people's expectations about what's possible,' says Morgenthaler. 'Apple has crossed a threshold; people now expect that you should be able to expect to speak ordinary English — and be understood. Siri has cracked the code.' The threshold, from mere speech recognition to natural language input and understanding, is one that Google cannot cross by replicating the technology or making an acquisition adds Morgenthaler. 'There's no company out there they can go buy.' Morgenthaler's comments echo the recent article in Forbes Magazine, 'Why Siri Is a Google Killer' that says that Apple's biggest advantage over any other voice application out there today is the massive data Siri will collect in the next 2 years — all being stored in Apple's massive North Carolina data center — that will allow Siri to get better and better. 'Siri is a new interface for customers wanting to get information,' writes Eric Jackson. 'At the moment, most of us still rely on Google for getting at the info we want. But Siri has a foot in the door and it's trusting that it will win your confidence over time to do basic info gathering.'"

RedEaredSlider writes "A group of researchers in Canada has decided to combine the mechanism geckos use to stick to walls with the simplicity of a tank tread. The result is a 'bot that can roll up smooth (and some not so smooth) surfaces. Such robots are easier to control than those that try to simulate walking directly."

MrSeb writes "When the Microsoft-Nokia strategic alliance was first announced in February, there was absolutely no mention of money: Nokia, seemingly on its own accord, had decided that Windows Phone 7 was the future of its smartphone efforts. A week later it emerged that Microsoft and Google had been competing for Nokia's affections — a bidding war that concluded with Microsoft agreeing to pay Nokia billions of dollars to help market and develop Windows phones. Fast forward to today and Nokia's CEO, Stephen Elop, is making rather odd comments about the tablet market: 'There’s a new tablet opportunity coming. We see the opportunity,' Elop said to Bloomberg Businessweek yesterday. Furthermore, he had only positive things to say about Windows 8 — that it's a "supercharged" version of WP7, but for tablets. Does that sound like Nokia is planning to bring out a Windows 8-powered tablet? Is it possible that Microsoft's multi-billion-dollar agreement with Nokia also included Windows 8?"

An anonymous reader writes "A tweet appeared from Raspberry Pi stating the launch of the $25 PC wasn't happening in November as expected. So I decided to investigate further and contacted Raspberry Pi to see what was going on. Eben Upton was kind enough to email me back and give us some good and bad news. The bad news is: we aren't getting the $25 PC this month as expected. But that's where the bad news ends, as it is still arriving in 2011 for some people. Eben confirmed that an order has been placed for 10,000 units, but they won't arrive until the end of November. That means we will see Raspberry Pi go up for sale in December, but it won't be a typical 'get as many out the door as you can' launch. Those first 10k are earmarked for programmers as software is desperately required before a full consumer launch." Update: Apparently some of the details about the production of units and who can get one from the first batch have changed. Raspberry Pi has updated their front page with the latest information.

UnknowingFool writes "When the Courier project was leaked out, it was a bold look at how MS would design new tablets. Microsoft was currently selling tablets but they didn't make a dent in the market. The problem was it was too bold. According to the story Ballmer had two competing executive visions for tablets: J. Allard and Steven Sinofsky. Allard's vision was very different from MS thinking while Sinofsky's was more in line with existing Windows but was years away. Ballmer called on Gates to help and Gates met with Allard. Gates was apparently troubled on how Courier would not mesh with Windows or Office. The project was cancelled shortly thereafter. An interesting detail was that Courier was more complete than most outsiders knew. While there was no one prototype that unified all the concepts of Courier, there were parallel efforts in the different aspects of it."
