Should We Fill the Sahara With Solar Panels? (bbc.com) 386

An anonymous reader writes: A panel of experts at the BBC discuss the possibility of re-purposing the Sahara Desert. Instead of having over 9 million square kilometers of barren sand, we could start a massive project to gradually fill it with solar panels. The remarks are illuminating: "The technology is good. It's matured a lot in the last few years in terms of thermal storage. And the Sahara desert is so big that if there is cloudy weather, it's localized, and with thermal storage, it can provide absolutely reliable power." The difficulties turn out to be mostly political: "The biggest potential pitfall is that it's politically complicated. You're not going to develop solar energy in the Sahara unless you have a very strong state involvement, both on the side of the consumers and the project developers." And one of the panelists points out that Africa must have a large share of the benefits: "Things have changed. Africans are self-confident now, they want to participate in their development, and they want to have part of their resources, they are not just there to always give to the rest of the world and remain poor."

Lessig: Future Tech Will Help Privacy Catch Up With the Internet (wsj.com) 35

An anonymous reader writes: In a new interview, Harvard law professor Lawrence Lessig shared his view of the future of privacy in this age of data breaches. "The average cost per user of a data breach is now $240 — think of businesses looking at that cost and saying, 'What if I can find a way to not hold that data, but the value of that data?' When we do that, our concept of privacy will be different. Our concept so far is that we should give people control over copies of data. In the future, we will not worry about copies of data, but using data." Lessig sees new technological advancements as the key to shoring up our privacy, which has been eroding since the dawn of the internet. Being able to act on data without holding it is key: "If I ping a service, and it tells me someone is over 18, I don't need to hold that fact. The level of security I have to apply [is not] the same [that] would be required if I was holding all of this data on my servers. This will radically change the burden of security that people will have."

Physicists Figure Out How To Make Cleaner Fuel Cells (eurekalert.org) 32

Mal-2 writes: An international group of scientists from Russia, France, and Germany have developed ion-exchange synthetic membranes based on amphiphilic compounds that are able to convert the energy of chemical reactions into electrical current. The new development described in the journal Physical Chemistry, Chemical Physics could potentially be used in fuel cells, and in separation and purification processes (abstract).

The molecules in question, with the working names A-Na and Azo-Na, are promising substances that are classified as benzenesulfonates. They are wedge-shaped and can independently assemble themselves into supramolecular structures — complex organized groups of multiple molecules. Depending on the conditions set by the scientists, the molecules form discs, which, in turn, form columns with ion channels inside.

Robot Mule Put Out To Pasture By Marine Corps (nbcnews.com) 153

An anonymous reader sends word that the Marines have decided that Boston Dynamics' robotic pack mules are too noisy to use. NBC reports: The massive robotic mule developed by Alphabet-owned Boston Dynamics won't see combat with U.S. Marines. LS3 (Legged Squad Support Systems) was meant to carry cargo for weary soldiers in the field. Funded by the Defense Advanced Research Projects Agency, or DARPA, the robot was capable of walking with 400 pounds of equipment on its back. LS3 could run for 24 hours straight on a 20-mile mission across rough terrain. No controller was needed; it took visual and verbal cues from soldiers to find its way. So why doesn't the Marine Corps want to use it? The robot's gas-powered engine isn't exactly the stealthiest piece of technology.

Rail Gun Controller Lets You Pack the Heat of Your Air Soft Gun In Any FPS Game (hothardware.com) 44

MojoKid writes: The cool thing about playing Duck Hunt on the NES back in the day, was that you got to point a plastic gun at the television and shoot directly at fowl or clay discs. It offered a deeper level of immersion than what would have been possible with a standard controller. Such is the pitch for a new Kickstarter project called Rail Gun. Rail Gun is a series of attachments designed to work with your existing Air Soft gun. The pieces attach to any standard Air Soft gun to give you a "truly realistic and immersive experience for FPS games." There are five units that comprise the Rail Gun. The Main Unit houses the power and sensitivity buttons; the Jog Unit has an analog stick, special action button, and a few other components; the Weapon Unit lets you cycle through weapons, walk, drop items, and so forth; the Trigger Unit features the trigger and buttons for jumping, zooming, reloading, and crouching; and the USB Unit is what plugs into your PC or console. The Rail Gun uses fast rotation technology to track your vision based on where you're pointing your Air Soft gun. It also uses an algorithm to enhance aiming by detecting minor hand trembles, and you can adjust the sensitivity of this to your liking.

Tech Segments Facing Turbulence In 2016 (dice.com) 72

Nerval's Lobster writes: David Foote, an analyst who accurately predicted the tech industry's job growth in 2015, is back with some new predictions about which segments will do well in 2016 (Dice link). At the top of his list: DevOps, cloud and software architects, and cybersecurity experts. Those that won't perform well? SAP specialists, storage 'gurus,' and network managers could all face some headwinds. 'Companies are continuing to outsource infrastructure and that will reduce the need for network specialists except for network security which will remain in-house,' he says. Whether or not he's right about which parts of the tech industry will do better than others, there are also increasing signs that things could get very tight from a funding perspective for startups, as even the so-called 'unicorns' risk seeing investor money (and customers) dry up.

Google Glass For Work Is Sleeker, Tougher and Foldable (engadget.com) 71

An anonymous reader writes: FCC filings published today are offering a glimpse of the "Enterprise Edition" of Google Glass. According to Engadget: "...The work-focused eyepiece touts a much slicker (and likely more durable) design with both a larger display prism and a hinge that lets you fold it up for travel. The test photos also reveal a spot for a magnetic battery attachment and what looks to be a speedier Atom processor. There's still no word on when Google will announce this headset, although the FCC presence hints that it might not take long."

HAMR Hard Disk Drives Postponed To 2018 (anandtech.com) 122

An anonymous reader writes: Unfortunately the hard disk drive industry is not ready to go live with Heat-assisted Magnetic Recording (HAMR). The technology is yet not reliable enough for mass production. Over the years, producers of hard drives, platters and recording heads have revealed various possible timeframes for commercial availability of drives with HAMR technology. Their predictions were not accurate. The current goalpost is set to year 2018. While solid state disks based on Flash memory keep seeing rapid improvements as well, HDDs still kick butt in scenarios where high areal density is more important than ripping transfer speeds. The areal density of HAMR products is predicted to exceed 1.5 Tb per square inch.

Four Factors That Will Push VR Forward in 2016 (technologyreview.com) 64

At MIT Technology Review, Rachel Metz lists four factors she believes will mean great advancements for virtual reality in the next year. More and better games; wider adoption of specialized cameras for capturing the deep imagery that immersive worlds require; specialized presentation techniques that supplement VR with physical cues like temperature or direction; and availability of better viewing hardware. That better hardware seems poised to take off. According to the article, Facebook-owned Oculus’s first consumer headset, Rift, is slated for release in the first quarter of the year, while the HTC Vive—a headset created by smartphone maker HTC and video-game company Valve—is set to be available to consumers in April. Sony, meanwhile, is building its own headset, called PlayStation VR, which the company says will be released in the first half of the year.

Switzerland Moves Toward a Universal Phone Charger Standard (vice.com) 401

Press2ToContinue writes: Apple's Lightning cable cartel be damned: Switzerland is moving forward with a plan for a single, universal phone charger across the country, standardizing phone chargers across the board. While the exact standard hasn't been mentioned yet, it wouldn't be hard to guess the standard: Micro USB, used across phone platforms, most especially Android, which has a gigantic chunk of the cell phone market worldwide.

The likely loser? Apple, which has relied on proprietary chargers since introducing the iPhone in 2007. While many companies have tried releasing generic cables, Apple often relies on DRM software to ensure that it's an Apple certified cable, charging $19 a piece for the Lightning charger used by the iPhone 5 and 6 and similar models.

What do you think -- are government-mandated standards for chargers a good idea? Despite the success of the standard household 3-prong electrical plug, doesn't this hamper progress?
China seems to have done most of the work on the wall-circuit side of the equation,several years ago. But as to the "standard" 3-prong plug, any particular plug type is only as universal as the sockets and voltages they supply.

Ask Slashdot: State-of-the-Art In Amateur Book Scanning? 122

An anonymous reader writes: I have a shelf full of books and other book-like things ranging from old to very old that I would like to turn into PDFs (or other similarly portable format), and have been on a slow-burn quest for the right hardware and method to do so on a budget. These are mostly sentimental — things handed down over generations, and they include family bibles, notebooks, and photo albums, as well as some conventional — published, bound — books from the late 19th and early 20th Century. None of them are especially valuable as antiques, as far as I know; my goals in preserving them are a) to make them available to other people in my family who are into genealogy or just nostalgia, and b) so I can read some of those old, interesting books (et cetera) without endangering them any more than it takes to scan them once. I was intrigued by the (funded, but not yet available) scanner mentioned earlier this year on Slashdot; it seems to do a lot of things right, but like any crowdfunded project, the proof is in the pudding, and the pudding hasn't yet arrived. It's also cheap, and that fits my household budget. What methods and hardware are you using to scan old documents? Any tips you have from a similar project, with regard to hardware, treatment of the materials being scanned, light sources, file formats, clean-up and editing tools, file-size-vs-resolution tradeoffs? In the end, I'm likely to err toward high-resolution scans, since they can be knocked down to size later if need be, but I'd be interested in hearing about what tradeoffs you've found to work for you.

One big question that I'd like to have answered: Is there stand-alone Free / Open Source software, or even just cheap software (I am mostly on Linux, by choice, but won't leap onto a sword to keep my Free Software purity) that makes for easy correction of the distortion introduced by camera-based imaging? If I could easily uncurl and keystone-correct pages, then a lot of input methods (even my phone) are suddenly much more attractive. My old Casio camera could do this 10 years ago, but I haven't found a free software desktop utility that lets me turn photos into nicely squared-up pages.

Ask Slashdot: Any Dishwasher Hackers Out There? 481

New submitter writes: I just replaced my dishwasher with a basic, inexpensive Sears model. It works fine, but only has 3 different wash cycles. I'm betting that the code to manage more cycles (as in more-expensive models) is already in the microcontroller and just needs inputs to select it. Is there any information available on this? Beyond dishwashers, have you done any useful hacks to household appliances more generally? I'd probably support a Kickstarter project that adds nice wireless notifications to my oven, clothes washer, and dishwasher.

Fujitsu Spins Off Its PC and Mobile Divisions (engadget.com) 100

An anonymous reader writes: Back in February, Sony unloaded the part of its business that built PCs. Now, a year later, competitor Fujitsu is doing the same. The company announced it would be spinning off its PC and mobile business, effective 1 February 2016. Your first reaction was probably, "Fujitsu had a PC and mobile business?" You're not alone, and this is likely why the split is happening. In their press release, they say, "With the ongoing commoditization of ubiquitous products, mainly of PCs and smart phones, it has become increasingly difficult to achieve differentiation, and competition with emerging global vendors has intensified." More simply: they couldn't make a competitive product. Hopefully, this is the start of a trend; the race to zero in the Windows laptop market is finally killing off some of the participants.

Marc Andreessen Describes Vision of 'Ambient Computing' (telegraph.co.uk) 106

An anonymous reader writes: Marc Andreessen, co-founder of Netscape, is one of the biggest investors in technology. In an interview with The Telegraph, he spoke about how he envisions the future of computing. It's essentially an extension on the idea of the "Internet of Things." He thinks mobile phones will begin to be replaced in just 10 years. "The idea that we have a single piece of glowing display is too limiting. By then, every table, every wall, every surface will have a screen or can project." Within 20 years, he expects most new physical objects to have some sort of chip implanted within them. "The end state is fairly obvious — every light, every doorknob will be connected to the internet." The term for this is "ambient computing." There will obviously be a transition period — perhaps the so-called internet of things is just an early phase of that transition. But with powerful chips and sensors becoming incredibly cheap, Andreessen's scenario seems possible. I guess it's time to get cracking on those security and privacy concerns.

Amazon Makes It Almost Impossible To Calculate Their "Virtual CPU" Equivalent (informationweek.com) 114

dkatana writes: AWS started out defining its virtual CPUs as being composed of EC2 compute units, or ECUs, which it defined as an equivalent to a physical Xeon processor. However, a virtual CPU now looks suspiciously variable... A virtual CPU is whatever Amazon wants to offer in an instance series. The user has no firm measure to go by. From the article: [B]y doing a little math, you could actually compare what you were getting in virtual CPUs in EC2 versus Azure. Also by doing a little math, you knew how to compare one Amazon instance to another based on the ECU count in each virtual CPU. Microsoft didn't look too bad in the comparison. That is one of the casualties of the nomenclature change. I have searched for updated information on how a virtual CPU is measured and found nothing comparable to the definition of the 2012 ECU measure. I have questioned Amazon representatives three times between Oct. 27 and Dec. 21, and don't have much of an answer."

Forrest Mimms On Modern Air Travel With a Bag Full of Electronics 169

Evidently even Forrest Mimms isn't famous enough to fly without hassle when carrying a briefcase full of electronics; he writes at Make about his experiences, both before and after 2001. A relevant slice: After police were called when I was going through security at the San Antonio International Airport and after major problems going through security in Kona, Hawaii, I finally realized the obvious: Most people who don’t make things have no idea how to evaluate homemade equipment. Some are terrified by exposed wires and circuit boards, maybe because of bomb scenes in movies. So I gave up. Now my carryon bag is only half stuffed with electronics; the rest is shipped ahead via FedEx.

Pirate Bay Cofounder Utterly Bankrupts the Music Industry (torrentfreak.com) 261

JustAnotherOldGuy writes: Peter "brokep" Sunde, co-founder of The Pirate Bay, has built a machine that makes 100 copies per second of Gnarls Barkley's "Crazy," storing them in /dev/null (which is of course, deleting them even as they're created). The machine, called a "Kopimashin," is cobbled together out of a Raspberry Pi, some hacky python that he doesn't want to show anyone, and an LCD screen that calculates a running tally of the damages he's inflicted upon the record industry through its use. The 8,000,000 copies it makes every day costs the record industry $10m/day in losses. At that rate, they'll be bankrupt in a few weeks at most.

Today, we have a leaked document, which Mozilla confirmed is legitimate. My favorite of the concepts is a Raspberry Pi-based keyboard.
