pacopico writes: HP Labs is trying to make a comeback. According to Businessweek, HP is building something called The Machine. It's a type of computer architecture that will use memristors for memory and silicon photonics for interconnects. Their plan is to ship within the next few years. As for The Machine's software, HP plans to build a new operating system to run on the novel hardware. The new computer is meant to solve a coming crisis due to limitations around DRAM and Flash. About three-quarters of HP Labs personnel are working on this project.

sciencehabit writes: Even though daytime temperatures in the tropics of Mars can be about –20C, a summer afternoon there might feel about the same as an average winter day in southern England or Minneapolis. That's because there's virtually no wind chill on the Red Planet, according to a new study — the first to give an accurate sense of what it might feel like to spend a day walking about on our celestial neighbor. "I hadn't really thought about this before, but I'm not surprised," says Maurice Bluestein, a biomedical engineer and wind chill expert recently retired from Indiana University–Purdue University Indianapolis. The new findings, he says, "will be useful, as people planning to colonize Mars need to know what they're getting themselves into."

New submitter green453 writes: 'As a Houston resident with limited home broadband options, I found the following interesting: Dwight Silverman of the Houston Chronicle reports (warning: paywalled) that Comcast plans to turn 50,000 home routers into public Wi-Fi hotspots without their users providing consent. Comcast plans to eventually convert 150,000 home routers into a city-wide WiFi network. A similar post (with no paywall) by the same author on the SeattlePI Tech Blog explains the change. From the post on SeattlePI: "What's interesting about this move is that, by default, the feature is being turned on without its subscribers' prior consent. It's an opt-out system – you have to take action to not participate. Comcast spokesman Michael Bybee said on Monday that notices about the hotspot feature were mailed to customers a few weeks ago, and email notifications will go out after it's turned on. But it's a good bet that this will take many Comcast customers by surprise."' This follows similar efforts in Chicago and the Twin Cities.

An anonymous reader writes "South African makerstore OpenHardware.co.za has designed and built a new RepRap-derivative 3D printer which it plans to sell for less than R5000 ($470). The first completed units are being put together now, with an eye to shipping late June. Store owner Peter van der Walt says that he designed Babybot — which has a print area equivalent to a RepRap Prusa Mendel-style machine — in order to reduce build and support costs. He's been selling various RepRap designs in kit form for two years, but as they become more popular is struggling to keep up with demand and handle returns. By sourcing more materials locally — he also designs his own controller boards — he's looking to beat the likes of RS Components and large shopping chains which have begun shipping the likes of Cubify in the country."

An anonymous reader writes "South African education authorities are about to embark on an ambitious plan to take their schools textbook free, using the familiar refrain of one-tablet-per-child to do so. The education minister in Gauteng (the province which covers Johannesburg and Pretoria) has announced a plan to model new schools in the area on Sunward Park, a government school which went all-digital at the start of 2012. Other schools in the state will then follow, along with a plan to extend the project nationally."

mpicpp (3454017) writes in with news about Amazon's new payments service. "The company launched a service Monday known as Amazon Payments that allows consumers to use their Amazon accounts to send and receive money and shop online at 'thousands of sites other than Amazon.' It's accessible on both desktops and mobile devices. For businesses, Amazon is selling the service as a way to take advantage of its security and user data while saving time for new customers. There's no recurring fee for retailers to use the platform, though Amazon plans to take a standard cut of 2.9% from those businesses, plus $0.30 for each transaction of $10 or more. With more than 244 million active customer accounts, Amazon already has a massive base of potential users for the service. The effort represents a new front in its assault on eBay, which owns online payments service PayPal."

garyebickford writes 'Space Finance Group (in which I'm a partner) has launched a Kickstarter to fund updating the "famous Integrated Space Plan", created by Ron Jones at Rockwell International in the late 1980s and early 1990s, and can be found on walls in the industry even today. The new Plan will be a poster, but also will provide the initial core data for a new website. The permanent link will be thespaceplan.com. As additional resources become available the website will be able to contain much more information, with (eventually) advanced data management (possibly including sources like Linked Data) and visualization tools to become a resource for education, research, entertainment, and business analytics. The group also hopes to support curated crowdsourcing of some data, and is talking to Space Development companies about providing data about themselves. They hope to be able to construct new timelines and show the relations between events and entities — companies, agencies, people, etc.'

Freshly Exhumed (105597) writes 'Canada is poised to buy 65 Lockheed Martin Corp F-35 Joint Strike Fighter jets, sources familiar with the process told Reuters. A detailed, 18-month review of Canada's fighter jet needs has concluded that the government should skip a new competition and proceed with the C$9 billion ($8.22 billion) purchase, three sources said. When the F-35 purchase was first proposed, Canadians were alarmed by the colossal price tag, and also that no fly-off competition had been conducted or was planned. This latest news is sure to rekindle criticism that the RCAF's requirements seem to have been written after the fact to match the F-35's capabilities (or lack thereof)."

stephendavion (2872091) writes 'Passengers can now access free Wi-Fi at the world's busiest airport. Atlanta's Hartsfield-Jackson International Airport has dropped its $5 fee to access Wi-Fi in its terminals. "Now, Atlanta Mayor Kasim Reed and airport officials plan to celebrate the long-awaited arrival of the amenity at the airport Wednesday," reports Kelly Yamanouchi of The Atlanta Journal-Constitution. ... Interm airport manager Miguel Southwell tells Yamanouchi officials believe dropping the Wi-Fi charge will alleviate a "competitive disadvantage" for Hartsfield-Jackson.' I'm puzzled sometimes that so many airports do not yet offer free Wi-Fi, especially ones loaded with businesses (like Starbucks and McDonalds) that have made this a big draw in their non-airport locations. On the other hand, given a captive audience and the temptation for exclusive contracts, maybe I should be grateful that so many do have at least limited free coverage, and that the trend seems positive.

The Fuel 3-D website has a blurb that says, "The world’s first handheld point-and-shoot, full color 3D scanner. Our planned list price is $1500 but by placing your advanced order now you pay only $1,250. Fire up your creativity!" We've thought about getting a 3-D scanner ever since we first messed with a 3-D printer, but we've thought more about something in the sub-$300 price range than in $1000+ territory. But that's just us. There is no doubt a healthy market for 3-D scanners to use in commercial applications where $1250 (or even $1500) is hardly worth noticing. Ah, well. Maybe we need to look at the The DAVID website which describes their device as an "Incredibly Low-Cost 3D Scanner for Everyone!" Their 3-D starter kit is only $529 from a randomly-selected U.S. reseller, which isn't too bad compared to the alternatives. But waiting for prices in this market niche to come down is another possibility, and it's one a whole lot of individuals -- including us -- and smaller companies will probably choose.

An anonymous reader writes "Computer security experts from academia, industry and the larger security community have organized themselves into more than 30 teams to compete in DARPA's Cyber Grand Challenge, a tournament designed to speed the development of automated security systems able to defend against cyberattacks as fast as they are launched. The Challenge plans to follow a 'capture the flag' competition format that experts have used for more than 20 years to test their cyber defense skills. The winning team from the CGC finals stands to receive a cash prize of $2 million. Second place can earn $1 million and third place $750,000."

Lucas123 (935744) writes "Cody Wilson, the 26-year-old former law school student who published plans for printing 3D guns online, disputed claims by universities and government agencies that his thermoplastic gun design is unsafe. Wilson claims the agencies that tested the guns did not build them to spec. In a Q&A with Computerworld, he also addressed why he's continuing to press regulatory agencies to allow him to offer the plans again for upload after being ordered to take them down, saying it's less about the Second Amendment and more about the implications of open source and the digital age. "If you want to talk about rights, what does it mean to respect a civil liberty or civil right? Well, it means you understand there are social costs in having that right; that's why it deserves protection in the first place," he said. Wilson is also planning to release other gun-related project, though not necessarily a CAD design."

DroidJason1 (3589319) writes "Microsoft recently announced plans to reintroduce the Start Menu to Windows in an upcoming version of the operating system. While the plan was to roll out an update to Windows 8.1 and offer the Start menu later this year, it seems like this is no longer the case. Now Microsoft is reportedly looking to release the Start Menu with Windows 9, which is expected in April of 2015. Windows 8 and Windows 8.1 have faced a boat load of criticism and hatred, partly due to the removal of the Start button and Start menu. The restoration of a visible Start button on the taskbar was one of the key features of the Windows 8.1 update, released back in October of 2013."

An anonymous reader writes "Google is planning to spend over $1 billion on a fleet of satellites to extend Internet access to unwired regions around the world. 'The projected price ranges from about $1 billion to more than $3 billion, the people familiar with the project said, depending on the network's final design and a later phase that could double the number of satellites. Based on past satellite ventures, costs could rise. Google's project is the latest effort by a Silicon Valley company to extend Internet coverage from the sky to help its business on the ground. Google and Facebook Inc. are counting on new Internet users in underserved regions to boost revenue, and ultimately, earnings. "Google and Facebook are trying to figure out ways of reaching populations that thus far have been unreachable," said Susan Irwin, president of Irwin Communications Inc., a satellite-communications research firm. "Wired connectivity only goes so far and wireless cellular networks reach small areas. Satellites can gain much broader access."'"

As The Next Web reports, Samsung is finally bringing to market (in Russia, to start) a phone, the Samzung Z, running the Tizen OS. Like Android, Tizen is based on the Linux kernel, but it's intended for HTML5 apps rather than Android apps. It's not Samsung's first Tizen device, though; the second-generation of its Gear smart-watches are running Tizen as well. "Samsung earlier revealed plans for its first Tizen smartphones to be launched during its second quarter of business in 2014, which runs April to July, so it seems like smartphones other than Samsung Z could still be on their way. The Samsung executive said that Tizen devices could account for as much as 15 percent of Samsung’s mobile shipments per year, but Android will still be its main business."

An anonymous reader writes "Nick Pitton, the developer behind the Spirited Away Boiler Room VR experience, has released his second project: the bus stop scene from Studio Ghibli's famous movie My Neighbor Totoro, once again in virtual reality for the Oculus Rift. Pittom 'hand-painted' the textures in Photoshop to recreated the painted-background feel of the movie. For the characters (Totoro and the Catbus) he used a cel-shaded approached to approximate the animated look from the movie. For his next project, he plans to recreate the ship and characters from the acclaimed anime Cowboy Bebop."

An Associated Press story, as carried by the Philadelphia Inquirer, says that NASA plans to test this Tuesday on the Hawaiian island of Kauai a huge (110' diameter) parachute intended as a means to land big loads (like astronauts) on the surface of Mars. Says the story: "The skies off the Hawaiian island of Kauai will be a stand-in for Mars as NASA prepares to launch a saucer-shaped vehicle in an experimental flight designed to land heavy loads on the red planet. For decades, robotic landers and rovers have hitched a ride to Earth's planetary neighbor using the same parachute design. But NASA needs a bigger and stronger parachute if it wants to send astronauts there. ... During the flight, a high-flying balloon will loft the disc-shaped vehicle from the U.S. Navy's Pacific Missile Range Facility in Kauai to 23 miles over the Pacific where it will be dropped. Then it will fire its rocket motor to climb to 34 miles, accelerating to Mach 4. The environment at this altitude is similar to Mars' thin atmosphere. As it descends to Earth, a tube around the vehicle should inflate, slowing it down. Then the parachute should pop out, guiding the vehicle to a gentle splashdown in the Pacific."

TechCrunch is among the many outlets which carry news (based on a release from MIT professor Daniela Rus) of robots that take advantage of materials engineered to change shape with the application of heat. With carefully planned creases and slits "printed" into flat sheets of plastic, heat-induced deformation can be channeled to create complex three-dimentional shapes, something between origami and Shrinky-Dinks. The creases can also be used to create moving parts in the finished product, and -- as with papercraft -- folding, overlapping and other techniques can increase the stiffness or otherwise give useful properties to the robot bodies formed. From the article: "This project could also produce a variable resistor by opening or closing an electric component and even create metallic muscles that contract when heated or current is applied. It’s obviously still in very early stages right now but Rus and her team will exhibit the technology at the IEEE International Conference on Robotics and Automation this year and maybe, one day, our cake-like robotic servants will rise up and bake us."
