After Negative User Response, ChromeOS To Re-Introduce Support For Ext{2,3,4} 183

Posted by Soulskill
from the squeeky-wheels dept.
NotInHere writes: Only three days after the public learned that the ChromeOS project was going to disable ext2fs support for external drives (causing Linux users to voice many protests on websites like Slashdot and the issue tracker), the ChromeOS team now plans to support it again. To quote Ben Goodger's comment: "Thanks for all of your feedback on this bug. We've heard you loud and clear. We plan to re-enable ext2/3/4 support in immediately. It will come back, just like it was before, and we're working to get it into the next stable channel release."

Lockheed Claims Breakthrough On Fusion Energy Project 565

from the you-don't-have-long-to-invent-Mr.-Fusion dept.
Lockheed Martin claims it has made a significant breakthrough in the creation of nuclear fusion reactors. The company says it has proved the feasibility of building a 100MW reactor measuring only 7 feet by 10 feet. They say the design can be built and tested within a year, and they expect an operational reactor within a decade. The project is coming out of stealth mode now to seek partners within academia, government, and industry. "Lockheed sees the project as part of a comprehensive approach to solving global energy and climate change problems. Compact nuclear fusion would also produce far less waste than coal-powered plants, and future reactors could eliminate radioactive waste completely, the company said."

If Your Cloud Vendor Goes Out of Business, Are You Ready? 150

storagedude writes: With Amazon Web Services losing an estimated $2 billion a year, it's not inconceivable that the cloud industry could go the way of storage service providers (remember them?). So any plan for cloud services must include a way to retrieve your data quickly in case your cloud service provider goes belly up without much notice (think Nirvanix). In an article at Enterprise Storage Forum, Henry Newman notes that recovering your data from the cloud quickly is a lot harder than you might think. Even if you have a dedicated OC-192 channel, it would take 11 days to move a petabyte of data – and that's with no contention or other latency. One possible solution: a failover agreement with a second cloud provider – and make sure it's legally binding.

Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life 395

New submitter chaosdivine69 writes: According to Scientists at Nanyang Technology University (NTU), they have developed ultra-fast charging batteries that can be recharged up to 70 per cent in only two minutes and have a 20-year lifespan (10,000 charges). The impact of this is potentially a game changer for a lot of industries reliant on lithium ion batteries. In the car industry, for example, consumers would save on costs for battery replacement and manufacturers would save on material construction (the researchers are using a nanotube structure of Titanium dioxide, which is an abundant, cheap, and safe material found in soil). Titanium dioxide is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays. It is believed that charging an electric car can be done in as little as 5 minutes, making it comparable to filling up a tank of gasoline.

Can the Sun Realistically Power Datacenters? 237

1sockchuck writes: A massive solar array in central New Jersey provides the daytime power for a server farm delivering online financial services for McGraw Hill. The 50-acre field of photovoltaic solar panels symbolizes a new phase in the use of renewable energy in data centers. Massive arrays can now provide tens of megawatts of solar power for companies (including Apple) that can afford the land and the expense. But some data center thought leaders argue that these huge fields are more about marketing than genuinely finding the best approach to a greener cloud.

Lucas123 writes: The Anonabox router project, currently being funded through a Kickstarter campaign, has surpassed its original $7,000 crowdfunding goal by more than 10 times in just one day. The open source router device connects via Wi-Fi or an Ethernet cable making it harder for your IP address to be seen. While there have been other Tor-enabled routers in the past, they aren't small enough to fit in a shirt pocket like the Anonabox and they haven't offered data encryption on top of the routing network. The device, which is being pitched as a way for consumers to securely surf the web and share content (or allow businesses to do the same), is also being directed at journalists who may want to share stories in places where they might otherwise be censored.

Wind Power Is Cheaper Than Coal, Leaked Report Shows 610

Posted by Soulskill
from the tilting-at-coalmills dept.
merbs writes: A leaked report shows wind is the cheapest energy source in Europe, beating the presumably dirt-cheap coal and gas by a mile. Conventional wisdom holds that clean energy is more expensive than its fossil-fueled counterparts. Yet cost comparisons show that renewable energy sources are often cheaper than their carbon-heavy competition. The report (PDF) demonstrates that if you were to take into account mining, pollution, and adverse health impacts of coal and gas, wind power would be the cheapest source of energy.

Smart Battery Tells You When It's About To Explode 97

Posted by samzenpus
from the danger-will-robinson! dept.
sciencehabit writes Material scientists have found a clever way to alert users of damaged batteries before any hazard occurs. A typical lithium-ion cell consists of a lithium oxide cathode and a graphite anode, separated by a thin, porous polymer sheet that allows ions to travel between the electrodes. When the cell is overcharged, microscopic chains of lithium, called "dendrites," sprout from the anode and pierce through the polymer separator until they touch the cathode. An electrical current passing through the dendrites to the cathode can short-circuit the cell, which causes overheating and, in some cases, fire. Attempts to stop dendrite formation have met with limited success, so the researchers tried something different. They built a "smart" separator by sandwiching a 50-nanometer thin copper layer between two polymer sheets and connecting the copper layer to a third electrode for voltage measurement. When the dendrites reach the separator, the voltage between the anode and the copper layer drops to zero, alerting users that they should change the damaged battery while it is still operating safely—disaster averted.

Raspberry Pi Sales Approach 4 Million 146

from the just-a-small-hobby dept.
Eben Upton's reboot of the spirit of the BBC Micro in the form of the Raspberry Pi would have been an interesting project even if it had only been useful in the world of education. Upton wanted, after all, to give the kind of hands-on, low-level interaction with computing devices that he saw had gone missing in schools. Plenty of rPis are now in that educational, inspirational role, but it turns out that the world was waiting (or at least ready) for a readily usable, cheap, all-in-one computer, and the Raspberry Pi arrived near the front of a wave that now includes many other options. Sales boomed, and we've mentioned a few of the interesting milestones, like the millionth unit made in the UK and the two-millionth unit overall. Now, according to TechCrunch the Raspberry Pi is getting close to 4 million units sold, having just passed 3.8 million, as reported in a tweet. If you have a Raspberry Pi, what are you using it for now, and what would you like to see tweaked in future versions?

Microsoft Develops Analog Keyboard For Wearables, Solves Small Display Dilemma 100

Posted by timothy
from the finger-spelling dept.
MojoKid writes Have you ever tried hunting and pecking on a miniature keyboard that's been crammed onto a smartwatch's tiny display? Unless the tips of your fingers somehow resemble that of a stylus, you're in for a challenge. Interestingly enough, it's Microsoft that might have the most logical solution for typing on small size displays running Google's Android Wear platform. Microsoft's research division has built an analog keyboard prototype for Android Wear that eliminates the need to tap at tiny letters, and instead has you write them out. On the surface, such a solution seems like you'd be trading one tedious task for another, though a demo of the technology in action shows that this could be a promising solution — watch how fast the guy in the video is able to hammer out a response.

ChromeOS Will No Longer Support Ext2/3/4 On External Drives/SD Cards 344

Posted by timothy
from the hope-this-is-reverted dept.
An anonymous reader writes Chrome OS is based on the Linux kernel and designed by Google to work with web applications and installed applications. Chromebook is one of the best selling laptops on Amazon. However, devs decided to drop support for ext2/3/4 on external drivers and SD card. It seems that ChromiumOS developers can't implement a script or feature to relabel EXT volumes in the left nav that is insertable and has RW privileges using Given that this is the main filesystem in Linux, and is thereby automatically well supported by anything that leverages Linux, this choice makes absolutely no sense. Google may want to drop support for external storage and push the cloud storage on everyone. Overall Linux users and community members are not happy at all.

Chris Gordon works for a high-technology company, but he likes analog meters better than digital readouts. In this video, he shows off a bank of old-fashioned meters that display data acquired from digital sources. He says he's no Luddite; that he just prefers getting his data in analog form -- which gets a little harder every year because hardly any new analog meters are being manufactured.

Where Intel Processors Fail At Math (Again) 239

rastos1 writes: In a recent blog, software developer Bruce Dawson pointed out some issues with the way the FSIN instruction is described in the "Intel® 64 and IA-32 Architectures Software Developer's Manual," noting that the result of FSIN can be very inaccurate in some cases, if compared to the exact mathematical value of the sine function.

Dawson says, "I was shocked when I discovered this. Both the fsin instruction and Intel's documentation are hugely inaccurate, and the inaccurate documentation has led to poor decisions being made. ... Intel has known for years that these instructions are not as accurate as promised. They are now making updates to their documentation. Updating the instruction is not a realistic option."

Intel processors have had a problem with math in the past, too.

AnandTech's Intro To Semiconductor Tech 21

from the absolutely-fab dept.
An anonymous reader writes: Computer hardware site AnandTech has posted a detailed introduction to semiconductor technology. It's deep enough to be insightful for understanding the chips that run your devices and the industry that built them, but also short enough that your eyes won't start bleeding in the process. The article starts by explaining why silicon is so important, and how a board is set up, structurally. Then it walks through transistor design and construction, and the underpinnings of CMOS logic. Finally, the article describes the manufacturing steps, including wafer creation, photolithography, and how metal is added/shaped at the end. They then go into the physics behind improving these components. It's a geeky and informative read.

from the better-picking dept.
mikejuk writes The Amazon Picking Challenge at ICRA (IEEE Robotics and Automation) 2015 is about getting a robot to perform the picking task. All the robot has to do is pick a list of items from the automated shelves that Amazon uses and place the items into another automated tray ready for delivery. The prizes are $20,000 for the winner, $5000 for second place and $1000 for third place. In addition each team can be awarded up to $6000 to get them and their robot to the conference so that they can participate in the challenge. Amazon is even offering to try to act as matchmaker between robot companies and teams not having the robot hardware they need. A Baxter Research Robot will be made available at the contest.

The Indiegogo crowdfunding campaign for an open-hardware cinema camera has closed far in the black, though the project continues to accept contributions. The Axiom's designers raised enough (€174,520, topping their €100,000 goal) to fund development of their stretch goals (remote control, active lens mount, active battery mount), and then some. If it actually gets built and catches on, it will be interesting to see what custom modules users come up with.

Ubisoft Claims CPU Specs a Limiting Factor In Assassin's Creed Unity On Consoles 338

Posted by timothy
from the bottlenecks-shift dept.
MojoKid (1002251) writes A new interview with Assassin's Creed Unity senior producer Vincent Pontbriand has some gamers seeing red and others crying "told you so," after the developer revealed that the game's 900p framerate and 30 fps target on consoles is a result of weak CPU performance rather than GPU compute. "Technically we're CPU-bound," Pontbriand said. "The GPUs are really powerful, obviously the graphics look pretty good, but it's the CPU that has to process the AI, the number of NPCs we have on screen, all these systems running in parallel. We were quickly bottlenecked by that and it was a bit frustrating, because we thought that this was going to be a tenfold improvement over everything AI-wise..." This has been read by many as a rather damning referendum on the capabilities of AMD's APU that's under the hood of Sony's and Microsoft's new consoles. To some extent, that's justified; the Jaguar CPU inside both the Sony PS4 and Xbox One is a modest chip with a relatively low clock speed. Both consoles may offer eight CPU threads on paper, but games can't access all that headroom. One thread is reserved for the OS and a few more cores will be used for processing the 3D pipeline. Between the two, Ubisoft may have only had 4-5 cores for AI and other calculations — scarcely more than last gen, and the Xbox 360 and PS3 CPUs were clocked much faster than the 1.6 / 1.73GHz frequencies of their replacements.

Reverse Engineering the Oculus Rift DK2's Positional Tracking Tech 26

Posted by timothy
from the blink-and-you-won't-miss-it dept.
An anonymous reader writes The Oculus Rift DK2 VR headset hides under its IR-transparent shell an array of IR LEDs which are picked up by the positional tracker. The data is used to understand where the user's head is in 3D space so that the game engine can update the view accordingly, a critical function for reducing sim sickness and increasing immersion. Unsurprisingly, some endeavoring folks wanted to uncover the magic behind Oculus' tech and began reverse engineering the system. Along the way, they discovered some curious info including a firmware bug which, when fixed, revealed the true view of the positional tracker.

alphadogg (971356) writes A startup called Antumbra run by 5 college students is looking to throw a little soothing light on this situation: People who hunker down in front of their computers until the wee hours, until it feels like their eyes might fall out. Antumbra's open-source-based Glow, which launches in a limited beta of 100 $35 units on Thursday, is a small (1.5" x 1.5"x 0.5") doohickey that attaches to the back of your computer monitor via USB port and is designed to enhance your work or gaming experience — and lessen eye strain — by spreading the colors from your screen onto the wall behind it in real time. The idea is to reduce the contrast in colors between the computer screen and the background area. The the idea might not be new, and people have been home-brewing their own content-driven lighting like this for a while, but this is the first I've seen that looks like a simple add-on.
