Ubuntu Edge Draws Nearly $13M, But Falls Short of Indiegogo Goal 125

Posted by timothy from the but-it's-still-a-good-idea dept.
Nerval's Lobster writes "The crowdfunding campaign to build an Ubuntu-powered smartphone has fallen short of its ambitious goal. Canonical, which works with the open-source community to support Ubuntu worldwide, decided to fund its Ubuntu Edge smartphone via crowdfunding Website Indiegogo. The funding goal was set at $32 million, and at first it looked as if the project had enough momentum to actually succeed: within the first 24 hours of the project's July 22 launch, some $3.45 million had poured in. But that torrent of cash soon slowed to a trickle. In the end, the campaign managed to amass $12,809,906 by its August 21 closing. Nonetheless, Canonical did its best to put a brave face on the situation. 'While we passionately wanted to build the Edge to showcase Ubuntu on phones, the support and attention it received will still be a huge boost as other Ubuntu phones start to arrive in 2014,' the organization wrote in a posting. 'Thousands of you clearly want to own an Ubuntu phone and believe in our vision of convergence, and rest assured you won't have much longer to wait.'" Update: 08/22 16:14 GMT by T : Oops -- headline edited to reflect that the Edge was an Indiegogo project, rather than Kickstarter.

Physicists Find Solid-State 'Triple Point' In Material That Conducts, Insulates 35

Posted by Soulskill from the it-slices-it-dices-it-makes-julienne-fries dept.
vinces99 writes "It is well known to scientists that the three common phases of water – ice, liquid and vapor – can exist stably together only at a particular temperature and pressure, called the triple point. Also well known is that the solid form of many materials can have numerous phases, but it is difficult to pinpoint the temperature and pressure for the points at which three solid phases can coexist stably. Physicists now have made the first-ever accurate determination of a solid-state triple point in a substance called vanadium dioxide, which is known for switching rapidly – in as little as one 10-trillionth of a second – from an electrical insulator to a conductor, and thus could be useful in various technologies. 'These solid-state triple points are fiendishly difficult to study, essentially because the different shapes of the solid phases makes it hard for them to match up happily at their interfaces,' said David Cobden, a University of Washington physics professor who is lead author of a paper about the research published in Nature. 'There are, in theory, many triple points hidden inside a solid, but they are very rarely probed.'"

MIT Reports 400 GHz Graphene Transistor Possible With 'Negative Resistance' 123

Posted by Unknown Lamer from the switch-faster dept.
An anonymous reader writes "The idea is to take a standard graphene field-effect transistor and find the circumstances in which it demonstrates negative resistance (or negative differential resistance, as they call it). They then use the dip in voltage, like a kind of switch, to perform logic. They show how several graphene field-effect transistors can be combined and manipulated in a way that produces conventional logic gates. Graphene-based circuit can match patterns and it has several important advantages over silicon-based versions. Liu and co can build elementary XOR gates out of only three graphene field-effect transistors compared to the eight or more required using silicon. That translates into a significantly smaller area on a chip. What's more, graphene transistors can operate at speeds of over 400 GHz."

Intel, Unisys Partner On New Range of Servers 46

Posted by Soulskill from the RISC-is-our-business dept.
itwbennett writes "Unisys is primarily a services and consulting company with just a small amount of revenue coming from hardware, but they may be on to something new that could 'could give them a competitive advantage at a time when the big guns are a mess,' says Andy Patrizio. Unisys and Intel are are set to introduce on September 9 a new kind of secure computing platform designed to as a replacement platform for RISC systems running mission-critical cloud and big data workloads. 'It sounds funny to hear Intel talk about RISC migration since it is in the RISC business with the Itanium,' says Andy Patrizio, 'but at this point, what's left? HP was the driving force behind Itanium and it's in chaos right now. IBM has a healthy RISC business, so the target is obviously what's left of the Sun installed base.'"

Germany Produces Record-Breaking 5.1 Terawatt Hours of Solar Energy In One Month 687

Posted by Soulskill from the go-big-or-go-home dept.
oritonic1 writes "Germany is rapidly developing a tradition of shattering its own renewable energy goals and leaving the rest of the world in the dust. This past July was no exception, as the nation produced 5.1 TWh of solar power (PDF), beating not only its own solar production record, but also eclipsing the record 5TWh of wind power produced by German turbines in January. Renewables are doing so well, in fact, that one of Germany's biggest utilities is threatening to migrate to Turkey."

NHTSA Gives the Model S Best Safety Rating of Any Car In History 627

Posted by timothy from the still-betting-on-the-mack-truck dept.
cartechboy writes "Even crashing into a wall is good news nowadays for Tesla Motors. Independent testing by the National Highway Traffic Safety Administration (NHTSA) has awarded the company a 5-star safety rating, not just overall, but in every subcategory. While its five-star score across the board has been attained by other vehicles (around one percent of all cars tested are capable of such a score) its ratings in individual categories are higher than any other vehicle, including larger SUVs and minivans. What's really interesting is that part of the safety rating may be because the car is electric."

Dell Dumps Keyboardless Windows RT Tablets 186

Posted by Unknown Lamer from the you-win-this-round-laptops dept.
jfruh writes "On Friday, Dell was selling Windows RT tablets for as low as $300. By this morning, the cheapest one on offer was $479. The difference? The only tablets they're selling now come bundled with keyboards, which may indicate that customers are finding even the Metro-focused RT version of Windows 8 too irritating to navigate by touch alone. (If you really want a 10-inch Dell tablet without a keyboard it looks like you can still get one on Amazon, at least for the time being.)"

Daniel_Stuckey writes "The rise of autonomous cars might turn out to be more rapid than even the most devout Knight Rider fans were hoping. According to a new report from Navigant Research, in just over two decades, Google Cars and their ilk will account for 75 percent of all light vehicle sales worldwide. In total, Navigant expects 95.4 million autonomous cars to be sold every year by 2035. That's pretty astonishing. For one thing, that's more cars than are built every year right now."

How One Programmer Is Coding Faster By Voice Than Keyboard 214

Posted by samzenpus from the greased-lightning dept.
mikejuk writes "Is it possible that we have been wasting our time typing programs. Could voice recognition, with a little help from an invented spoken language, be the solution we didn't know we needed? About two years ago Tavis Rudd, developed a bad case of RSI caused by typing lots of code using Emacs. It was so severe that he couldn't code. As he puts it: 'Desperate, I tried voice recognition'. The Dragon Naturally Speaking system used by Rudd supported standard language quite well, but it wasn't adapted to program editing commands. The solution was to use a Python speech extension, DragonFly, to program custom commands. OK, so far so good, but ... the commands weren't quite what you might have expected. Instead of English words for commands he used short vocalizations — you have to hear it to believe it. Now programming sounds like a conversation with R2D2. The advantage is that it is faster and the recognition is easier — it also sounds very cool and very techie. it is claimed that the system is faster than typing. So much so that it is still in use after the RSI cleared up."

The World's First CPU Liquid Cooler Using Nanofluids 79

Posted by samzenpus from the keeping-cool dept.
An anonymous reader writes "CPU water cooling may be more expensive than air cooling, but it is quieter and moves the bulk away from your CPU. It's also improving, as Zalman has just demonstrated with the announcement of the Reserator 3. Zalman is claiming that the Reserator 3 is the world's first liquid cooler to use nanofluids. What's that then? It involves adding refrigerant nanoparticles to the fluid that gets pumped around inside the cooler transporting the heat produced by a CPU to the radiator and fan where it is expelled. By using the so-called nanofluid, Zalman believes it can offer better cooling, and rates the Reserator 3 as offering up to 400W of cooling while remaining very quiet. The fluid and pump is supplemented by a dual copper radiator design and "quadro cooling path," which consists of two copper pipes sitting behind the fan and surrounded by the radiators. The heatsink sitting on top of the CPU is a micro-fin copper base allowing very quick transfer of heat to the nanofluid above."

At TedxMileHigh in Denver, Colo., 17-year-old Easton LaChappelle demonstrated his robotic arm, and how he constructed the arm to keep costs low. 'So in the end, I built this robotic arm up to the shoulder which was extremely strong,' LaChapelle said. 'It could toss balls to you, it could shake your hand, it could pretty much do anything a human could if you program it correctly.'"

Samsung SSD 840 EVO 250GB & 1TB TLC NAND Drives Tested 156

Posted by Soulskill from the stores-like-a-storage-device dept.
MojoKid writes "Samsung has been aggressively bolstering its solid state drive line-up for the last couple of years. While some of Samsung's earlier drives may not have particularly stood-out versus the competition at the time, the company's more recent 830 series and 840 series of solid state drives have been solid, both in terms of value and overall performance. Samsung's latest consumer-class solid state drives is the just-announced 840 EVO series of products. As the name suggests, the SSD 840 EVO series of drives is an evolution of the Samsung 840 series. These drives use the latest TLC NAND Flash to come out of Samsung's fab, along with an updated controller, and also feature some interesting software called RAPID (Real-time Accelerated Processing of IO Data) that can significantly impact performance. Samsung's new SSD 840 EVO series SSDs performed well throughout a battery of benchmarks, whether using synthetic benchmarks, trace-based tests, or highly-compressible or incompressible data. At around $.76 to $.65 per GB, they're competitively priced, relatively speaking, as well."

Dishwasher-Size, 25kW Fuel Cell In Development 379

Posted by Soulskill from the does-it-clean-my-dishes dept.
mcgrew writes "Forbes has an article about a new type of fuel cell that is 90% less costly than current cells at one tenth the size (making it the size of a dishwasher), with far higher efficiency than current cells. It runs at only 149 degrees Celsius (300F) . It was jointly developed by Diverse Energy and the University of Maryland. 'The first-generation Cube runs off natural gas, but it can generate power from a variety of fuel sources, including propane, gasoline, biofuel and hydrogen. The system is a highly efficient, clean technology, emitting negligible pollutants and much less carbon dioxide than conventional energy sources. It uses fuel far more efficiently than an internal combustion engine, and can run at an 80 percent efficiency when used to provide both heat and power.' It produces enough power to run a moderate-sized grocery store, or five homes. A smaller, home-sized unit is on the way. Is the municipal power plant on the way out?"

Google Glass Integration For Cars Is Coming: Neat Idea Or Crazy Town? 102

Posted by timothy from the save-one-hand-for-your-sandwich dept.
cartechboy writes "Americans have enough trouble keeping from texting their way to dangerous — or worse — situations in cars. But now car makers, looking to differentiate with tech integrations and after jamming iPhone everywhere, are working hard at integrating Google Glass into vehicles. Consider this quote: 'Within seconds, I've got step-by-step directions to a coffee shop down the street beamed directly to my eyeballs.' Aside from being a little Jetsons, sounds potentially problematic. (Note, Mercedes had been doing R&D since July.) It goes without saying that someone is working on an integration of their own with a Tesla Model S. There is a coolness factor, there may be some utility — but not sure this is a great idea."

Wireless Devices Go Battery-Free With New Communication Technique 111

Posted by Soulskill from the harvesting-energy-from-the-ether dept.
melios sends this quote from an University of Washington news release: "[E]ngineers have created a new wireless communication system that allows devices to interact with each other without relying on batteries or wires for power. The new communication technique, which the researchers call 'ambient backscatter,' takes advantage of the TV and cellular transmissions that already surround us around the clock. Two devices communicate with each other by reflecting the existing signals to exchange information. The researchers built small, battery-free devices with antennas that can detect, harness and reflect a TV signal, which then is picked up by other similar devices."

Ask Slashdot: Printing Options For Low-Resource Environments? 108

Posted by Soulskill from the 3d-print-yourself-a-nuclear-reactor dept.
bjhonermann writes "The Zambian government (along with partners) are currently rolling out an electronic medical records (EMR) system in public health facilities. The project has been going on for some time and is already in 600+ facilities with more than 700,000 patient records. One problem we're facing is that most information is still being double entered in the EMR as well as on primary paper documents at the facility, and sometimes additionally transcribed to paper registers. This double/triple entry takes time away from nurses who are already in short supply. There's an inability to fully move away from partially paper based systems both because clients often move between 'paper clinics' and 'electronic clinics' in the same communities and for follow-up care, and because the power systems in many sites are unreliable and require that there be sufficient paper backups of records for operations during periods where power is unavailable — perhaps for weeks at a time. We're providing solar panels and battery backups for sites, which work increasingly well with newer low power CPUs, but even if the power issue were solved this would not address the need for portable paper documents. The key objective of eliminating redundant manual entry of forms and paper registers by nurses might be accomplished if we had low cost low power B/W printers available at sites so that critical information could be entered electronically and then printed out as needed, either for client carried purposes (transfers/visits to 'paper facilities') or to serve as local backup when power is an issue. However, we've yet to find printing solutions that seem appropriate to the context and are hopeful the Slashdot crowd may have some ideas." Read on for some more specific criteria.

Court: NRC In Violation For Not Ruling On Yucca Mountain 258

Posted by Soulskill from the waste-not-want-not dept.
schwit1 sends this quote from an AP report: "The U.S. Court of Appeals for the District of Columbia ordered the [Nuclear Regulatory Commission] to complete the licensing process and approve or reject the Energy Department's application for a never-completed waste storage site at Nevada's Yucca Mountain. In a sharply worded opinion, the court said the nuclear agency was 'simply flouting the law' when it allowed the Obama administration to continue plans to close the proposed waste site 90 miles northwest of Las Vegas. The action goes against a federal law designating Yucca Mountain as the nation's nuclear waste repository. 'The president may not decline to follow a statutory mandate or prohibition simply because of policy objections,' Judge Brett M. Kavanaugh wrote in a majority opinion (PDF), which was joined Judge A. Raymond Randolph. Chief Judge Merrick B. Garland dissented. The appeals court said the case has important implications for the separation of powers between the executive and legislative branches of government. 'It is no overstatement to say that our constitutional system of separation of powers would be significantly altered if we were to allow executive and independent agencies to disregard federal law in the manner asserted in this case by the Nuclear Regulatory Commission,' Kavanaugh wrote. 'The commission is simply defying a law enacted by Congress ... without any legal basis.'"
