Lasrick writes "Dawn Stover has another great piece detailing why renewable energy will never provide us with all our energy needs. She deconstructs the unrealistic World Wildlife Fund report (co-written by several solar companies) that claims renewables will be able to provide 100% of the energy needs of several countries by 2050. From the article: 'When renewable energy experts get together, they tend to rhapsodize about the possibilities, believing that this will somehow inspire others to make their visions come true. But ambitious plans to power entire countries on solar energy (or wind or nuclear power, for that matter) don't have a snowball's chance in Australia. Such schemes are doomed to fail, and not because of the economic "reality" or the political "reality" -- however daunting those may be. They are doomed because of the physical reality: It's simply not physically possible for the world's human population to continue growing in numbers, affluence, and energy consumption without trashing the planet.'"

An anonymous reader writes "From the LA Times: 'Although Microsoft's 128 GB Surface Pro tablet is advertised as having 128 gigabytes of storage, the amount of space available to users is much less than that. That's also true for the 64 GB model. The Redmond, Wash., company confirmed Tuesday that the 128 GB Surface Pro has 83 GB of free storage, while the 64 GB version comes with 23 GB of open space. The reason for the difference: space already taken up by the tablet's Windows 8 Pro operating system and various preinstalled apps.' It's generally understood that your device won't have as much available storage as advertised, but it's usually a lot closer than this. Should device-makers be required to advertise how much storage is available to users, rather than the size of the storage media?"
waderoush writes "It may be the biggest art hack ever: a project to install 25,000 individually addressable LED lights on the western span of the San Francisco-Oakland Bay Bridge. New York-based 'light sculptor' Leo Villareal was in San Francisco last week to test the vast 'Bay Lights' art installation, which will officially debut on March 5 and last for two years; Xconomy has photos and video of Villareal running the light show from his laptop. To optimize his algorithms and figure out which patterns would be most interesting or arresting, Villareal needed to experiment on the bridge itself, says Bay Lights director Ben Davis, who has raised $5.8 million for the project so far. 'This has never been done before in history — literally debugging software 500 feet in the air, in front of a million people,' says Davis."
Space MMORPG EVE Online is best known for its amazing stories, and on Sunday it added a new epic tale. The leader of a huge coalition, preparing for a moderately sized assault, mis-clicked and accidentally warped himself into enemy territory without his support fleet, endangering his massive ship worth an estimated $3,500. Realizing the danger, he called upon every ally he could, and the enemy fleet rallied in turn, leading to an incredible 3,000-player battle. What's also impressive is that the EVE servers stayed up for the whole fight, when most MMOs struggle with even a few hundred players at the same time. The Penny Arcade report spoke with CCP Games for some information on how they managed that: "It’s hard to wrap your head around, but they sometimes move the in-game space itself. 'We move other solar systems on the node away from the fight. This disconnects anyone in those systems temporarily, but spares them from the ongoing symptoms of being on an overloaded server,' Veritas explained. 'It helps the fight system a little bit as well, especially if a reinforcement fleet is traveling through those other systems. This was done for the fight over the weekend, but is rare.' ... They do have a built-in mechanism for dealing with massive battles, however: They slow down time itself. ... Once server load reaches a certain point, the game automatically slows down time by certain increments to deal with the strain. Time was running at 10% speed during this 3,000-person battle, which is the maximum amount of time dilation possible."
An anonymous reader writes "Electronic devices are built to last, which make them very reliable. However, if during a hostile situation such a device has to be left behind or gets dropped, it will continue to function and could end up giving the enemy an advantage. With that in mind, DARPA has set about creating electronics that work for as long as necessary, but can be destroyed at a moment's notice. The project is called Vanishing Programmable Resources (VAPR). Its main aim is to develop so-called transient electronics that are capable of dissolving completely, or at the very least to the point where they no longer function. Destroying a VAPR device should be as easy as sending a signal to it or placing the device within certain conditions e.g. extreme heat or cold, that triggers the rapid destruction process."
noh8rz10 writes "Holy moly! iPad gets a heavyweight sibling, clicking in at 128GB. This places it in range of storage for Surface Pro and ultrabooks. It's clearly targeted at the professional market, as the press release cites X-rays and CAD files as reasons. Should Microsoft be afraid? Methinks so. Best part, pricing is growing by log 2. Just as the 32GB version is $100 more than the 16, and the 64 is $100 more than the 32, this new version is $100 more than the 64!" Update: 01/29 16:00 GMT by T : Here's Apple's announcement itself.
An anonymous reader writes "Boeing is currently dealing with a bit of a disaster as the company's 787 Dreamliner has been grounded due to safety concerns. Boeing is currently investigating the situation, but they aren't alone. Elon Musk, CEO of Tesla Motors and SpaceX, has stepped in to offer his help and technology if Boeing wants it. Musk has had to harness battery tech not only to run his Tesla Motors, but also to function flawlessly aboard SpaceX spacecraft as they travel both in and out of the Earth's atmosphere. If you need a battery to work at any altitude, you'd trust Musk to supply one, and that's exactly what he's offering Boeing."
crankyspice writes "Having recently picked up the Erector set I've wanted since I was a kid, I quickly found myself wanting to plunge deeper into makerspace by adding more sophisticated electronics to moving devices (rovers, maybe eventually flying bots). My first instinct was Arduino (maybe because of brand recognition?), but that got me thinking — what's the 'best' platform out there (most flexible)? Arduino with its myriad options (Nano, Mega, Uno, Mini)? PICAXE? BASIC Stamp? Raspberry Pi? (The latter seems like it would easily be the most flexible, but at greater cost in terms of weight and complexity.) I'm a hobbyist programmer, having learned C and C++ in college and recently re-learning Java (took and passed the Oracle Certified Professional exam, FWIW)..."
mikejuk writes "If you are a fan of the Sci-Fi sub-genre of robot apocalypses, you may well not want to give a robot a chainsaw to wield. If, on the other hand, you are a creative artist, then it seems well worth the risk, as this video demonstrates. In this case the robot is a standard industrial arm with an electric chainsaw mounted where the gripper would normally go. Exactly what the robot is doing isn't obvious to the viewer, but once it is finished the whole thing is disassembled to reveal two wooden stools and some interesting shapes. A robot with a chainsaw is just a subtractive 3D printer."
rtfa-troll writes "The Register tells us that Microsoft has begun squabbling with PC manufacturers over the reasons behind the failure of Windows 8. Microsoft is 'frustrated with major OEMs who didn't build nearly enough touch systems.' PC manufacturers have hit back, saying that they 'would have been saddled with the costs of a huge pile of unsold units,' claiming that customers actually avoided higher-end touch products which were available and instead bought lower-end, cheaper laptops while 'Microsoft is not blaming itself for' the failure of its own touch device, the Surface RT. The PC manufacturers' claims that touch is the problem seem to be backed by reviews, and some educational rants from users and opinions from user interface design experts. However, Microsoft sees this differently. Microsoft is planning to strike back at the PC vendors in February with Surface Pro; with a shorter battery life and much heavier than a normal tablet, this is being seen as a direct competitor to traditional laptops. By using its desktop operating system franchise as a lever, Microsoft will be able to enter the lower-specification end of the laptop market with a cost advantage which make make life difficult for former partners such as HP and Dell. We've discussed previously how some PC manufactures such as Dell have failed in generational change whilst others have diversified to survive market changes; Samsung with Android and the (still) bestselling Chromebook. ASUS with their successful Nexus tablets. We also discussed the ergonomic problems which are claimed to make touch screens unsuitable for PC use."
alphadogg writes "A rugged server from NCS Technologies introduced on Friday can withstand drops, will work in extreme temperatures and can be deployed via parachute into crisis areas or war zones if needed. The Bunker XRV-5241 is a 1U rack server designed for organizations such as the military and first responders that need servers in rugged environments. The server has been tested to meet U.S. Department of Defense specifications for environmental, temperature and shock requirements." Hope they drop some hardened screens, too, to help with setup.

MikeChino writes "Instructables member Patrik has successfully transformed an old HP5150 inkjet printer into a DIY bioprinter. To do this he removed the plastic covers and panels and rewired the paper handling mechanism. Then he prepped ink cartridges to be able to handle biological materials by opening the lid, removing the ink, and washing it out with deionized water. For his first experiment, he printed a simple solution of arabinose onto filter paper."
Jeremiah Cornelius writes "Blogger Adam Howard at Port3000 has a post about Google's exposure of thousands of publicly accessible printers. 'A quick, well crafted Google search returns "About 86,800 results" for publicly accessible HP printers.' He continues, 'There's something interesting about being able to print to a random location around the world, with no idea of the consequence.' He also warns about these printers as a possible beachhead for deeper network intrusion and exploitation. With many of the HP printers in question containing a web listener and a highly vulnerable and unpatched JVM, I agree that this is not an exotic idea. In the meanwhile? I have an important memo for all Starbucks employees."
redletterdave writes "On Friday morning, BitTorrent launched the alpha test of a new, free public service called BitTorrent Sync, which allows users to securely back up and sync files over the Web using BitTorrent's platform. Unlike competing services such as Box or Dropbox, BitTorrent Sync doesn't store files on remote servers (which means that no third party has access to one's files), and also has no storage limits other than what your devices can hold."
