DIY Web-Controlled Robot That Takes 1 Hour To Build 56

Posted by Soulskill from the make-it-crash-from-afar dept.
fixpert writes "We hooked up Pinoccio (an Open Source, wireless Arduino-compatible microcontroller) to a Pololu 3pi Robot to create an unmanned rover that can be driven via the Web. We posted a quick video where you can see us driving our Web Rover in Nevada all the way from Brazil. We used the iPhone's built-in accelerometer as a super-intuitive interface for driving the bot. You can read all about the project — how we built it, what you need to make your own (including source code), and a simulator of the accelerometer interface that you can play with. We're hoping to make Pinoccio the perfect platform for Software Developers to learn how to hack on DIY hardware."

Tesla Motors Battles the New York Times 700

Posted by Soulskill from the musk-faces-krugman-in-single-combat dept.
redletterdave writes "Days after the New York Times released a brutal review of Tesla's electric Model S sedan, Tesla CEO Elon Musk has fired back, claiming the Times article was completely bogus and misleading. In the article in question, Times writer John Broder took the Tesla Model S on a test drive from Washington to Boston, stopping at various service plazas in Delaware and Connecticut well within the projected 265-mile range of the car, as rated by the EPA. However, Broder's Tesla Model S, despite a heftier 85 kilowatt-hour battery for an extra 100 miles of range in 'ideal conditions,' died shortly before reaching its final destination. Broder blames the cold weather and heating issues for his abridged trip; Musk, however, claims the driver did not follow Tesla's instructions, which is why his trip was cut so short. 'We've taken great pains to ensure that the car works very well in the cold, which is why we're so incensed by this ridiculous article,' Musk said."

Turning a Kindle Fire HD Into a Power Tablet 81

Posted by timothy from the or-at-least-giving-it-some-muscle-tone dept.
jfruh writes "The Kindle Fire HD is in theory a powerful device at a reasonable price — but its Android-based OS is so oriented towards Amazon's ecosystem that it can be tricky to unlock its full potential. Still, with a little savvy you can get underneath the covers, improving battery life, getting full access to cameras and other devices, and even listening to music you've purchased through iTunes."

Home Server Or VPS? One Family's Math 380

Posted by timothy from the your-bandwidth-may-vary dept.
toygeek writes "Which is cheaper: Running a server from home, or renting a VPS (Virtual Private Server)? We're trying to pinch pennies where we can, and my son Derrick suggested upgrading an extra PC we have and running his Minecraft server at home. Would it save enough money to be worth it? I wanted to share the results of my analysis with my Slashdot brethren." The upshot in this case? "Overall it is VERY cost effective for us to run the home server."

First Impressions Inside the Project Holodeck VR Game World 49

Posted by samzenpus from the more-real-than-real dept.
Hesh writes "The space-pirates themed Project Holodeck game is a VR game that is initially targeted for the Oculus Rift and will marry VR with a world so interactive and immersive that it feels like you can reach out and touch it. Ben Lang over at RoadToVR recently got a chance to sit down with the team and try it out. He came out extremely impressed with how immersive the experience was: '...at one point I needed to set the Razer Hydra controllers down to adjust my helmet and I nearly tried to set them down on a virtual table next to me. There was no table in real life — had I not quickly realized what I was about to do, I would have dropped the controllers straight onto the floor below.'"

When 1 GB Is Really 0.9313 Gigabytes 618

Posted by timothy from the internal-struggle dept.
An anonymous reader writes "When it comes to RAM, as every geek knows, 1 GB does not mean 1 billion bytes.. it means 2**30 (1,073,741,824) bytes. However, several decades ago "they" decided that GB, MB, and KB would be interpreted differently when it comes to disk drives; 1 GB means exactly 1 billion bytes. Ed Bott points out that Microsoft's marketers and Windows kernel developers aren't on the same page when it comes to these units: the marketers use the more generous decimal interpretation, while Windows measures and reports capacity using the binary (2**30) measure. Careful customers who bother to check what they've got have been known to get peeved by the discrepancy."

Surface Pro Sold Out; Was It Just Understocked? 413

Posted by timothy from the ladies-and-gentleman-just-a-few-left dept.
TechCrunch is one of the many outlets to report that Microsoft's Surface Pro tablet computer sold out on its first day of wide availability. Business Insider points to Reddit threads complaining that "selling out" was largely a product of not having all that many in stock to begin with, in some cases not even enough to cover pre-ordered devices.

Apple Said To Be Working On a 'Watch-Like Device' 291

Posted by timothy from the i-watch-sounds-hinky dept.
The WSJ reports that Apple is "experimenting with designs for a watch-like device that would perform some functions of a smartphone, according to people briefed on the effort." An excerpt: The company has discussed such a device with its major manufacturing partner Hon Hai Precision Industry Co., one of these people said, as part of explorations of potentially large product categories beyond the smartphone and tablet. Apple's efforts come as companies have introduced various kinds of wearable gadgets, mainly designed to measure physical activity. More sophisticated devices face big technical challenges, but also are attracting investments from large technology companies. Foxconn, as Hon Hai is also known, has been working on a spate of technologies that could be used in wearable devices, one of these people said. In particular, the Taiwan-based company has been working to address the challenges of making displays more power-efficient and working with chip manufacturers to strip down their products."

What To Do When an Advised BIOS Upgrade Is Bad? 467

Posted by timothy from the wishful-thinking dept.
Bomarc writes "Twice now I've been advised to 'flash the BIOS to the latest,' once by a (major) hard drive controller maker (RAID); once by an OEM (who listed the update as 'critical,' and has removed older versions of the BIOS). Both times, the update has bricked an expensive piece of equipment. Both times, the response after the failed flash was 'It's not our problem, it's out of warranty.' Given that they recommended / advised that the unit be upgraded, shouldn't they shoulder the responsibility of BIOS upgrade failure? Also, if their design had sockets rather than soldering on parts, one could R/R the faulty part (BIOS chip), rather than going to eBay and praying. Am I the only one that has experienced this type of problem? Have you been advised to upgrade a BIOS (firmware); and the upgrade bricked the part or system? If so, what did you do? Should I name the companies?"

Samsung Laptop Bug Is Not Linux Specific 215

Posted by timothy from the using-french-or-korean-does-it-too dept.
First time accepted submitter YurB writes "Matthew Garrett, a Linux kernel developer who was investigating the recent Linux-on-Samsung-in-UEFI-mode problem, has bricked a Samsung laptop using a test userspace program in Windows. The most fascinating part of the story is on what is actually causing the firmware boot failure: 'Unfortunately, it turns out that some Samsung laptops will fail to boot if too much of the [UEFI] variable storage space is used. We don't know what "too much" is yet, but writing a bunch of variables from Windows is enough to trigger it. I put some sample code here — it writes out 36 variables each containing a kilobyte of random data. I ran this as an administrator under Windows and then rebooted the system. It never came back.'"

In 2011, Fracking Was #2 In Causing Greenhouse Gas In US 210

Posted by timothy from the with-a-little-ambition-it-can-rise-to-the-top dept.
eldavojohn writes "According to Bloomberg, drilling and fracking results in greenhouse gases second only to coal power plants in the United States. From the article, 'Emissions from drilling, including fracking, and leaks from transmission pipes totaled 225 million metric tons of carbon-dioxide equivalents during 2011, second only to power plants, which emitted about 10 times that amount.' According to Mother Jones, we now have more giant methane fireballs than any other country in the world and we can now see once dim North Dakota at night from space."

Can Legacy Dual-Core CPUs Drive Modern Graphics Cards? 159

Posted by Soulskill from the only-after-they-pass-driver's-ed dept.
MojoKid writes "A few weeks back, we discussed whether a new GPU like the GeForce GTX 660 could breathe new life into an older quad-core gaming system built in mid 2008. The answer concluded was definitely yes — but many readers asked to reconsider the question, this time using a lower-end dual-core Core 2 Duo. The Core 2 Duo CPU chip used was a first-generation C2D part based on Intel's 65nm Conroe core. It's clocked at 3GHz with 4MB of L2 cache and has a 1333MHz FSB. The CPU was paired with 3GB of DDR2-1066 memory. The long and short of it is, you can upgrade the graphics card on a six year-old dual core machine and expect to see a noticeable improvement in game performance — significant gains in fact, up to 50 percent or more."

Fox News: US Solar Energy Investment Less Than Germany Because US Has Less Sun 644

Posted by Soulskill from the Ra-likes-the-germans-better dept.
Andy Prough writes "Apparently those wise folks at Fox have figured out America's reluctance to invest as much money in solar energy as Germany — the Germans simply have more sun! Well, as Will Oremus from Slate points out, according to the U.S. Dept. of Energy's Solar Resource map comparison of the U.S. and Germany, nothing could be further from the truth — Germany receives as much sunlight as the least lit U.S. state — Alaska."

Apple Now the Top PC Vendor, For Some Values of PC 577

Posted by timothy from the is-it-personal-does-it-compute dept.
tsamsoniw writes "While research companies including IDC and Gartner deemed HP the PC leader for Q4 2012, Canalys has a different perspective. The analyst firm has declared Apple the top PC vendor for the past quarter, thanks in part to the booming success of the iPad and the iPad mini. By Canalys's reckoning, Amazon, too, now beats out the likes of Acer and Asus as leading PC vendors, having shipped 4.6 million Kindles in Q4."

Why Microsoft Got Into the Console Business 257

Posted by samzenpus from the origin-story dept.
An anonymous reader writes "Joachim Kempin, former vice president of Windows Sales, has explained how the original Xbox came to be. It turns out it was Sony's fault, simply because the Japanese company wasn't very friendly towards Microsoft, and Microsoft eventually decided they had to 'stop Sony.' Apparently, long before the Xbox was even an idea, Microsoft was trying to collaborate with Sony in a number of areas they thought there was overlap. That collaboration was sought before even Sony had a games console coming to market, and would have focused on products for the entertainment sector."

Linux-Friendly Mini PC Fast Enough For Steam Games 93

Posted by Soulskill from the tiny-penguins-with-hats dept.
crookedvulture writes "Barebones mini PCs have been around for a while, and the latest one from Zotac is pretty unique. For $270, the Zbox ID42 offers a Sandy Bridge CPU, a discrete GeForce graphics processor, and all the integrated I/O and networking you'd expect from a modern PC. You have to add your own memory, hard drive, and operating system, but the latter shouldn't cost you a dime. The Zbox works well with not only Windows, but also Linux. Ubuntu even recognizes the included remote, which can be used to wake up the system, control XBMC, and navigate Steam's Big Picture interface. Team Fortress 2 for Linux is actually playable, albeit at a relatively low resolution and detail level. The hardware seems better suited to casual games. Zotac also makes a Plus version of the Zbox that comes bundled with RAM and a hard drive, but it costs an extra $130, and you can get much better components if you add them yourself. The user-friendly chassis makes filling out the system a trivial undertaking."

Supercomputer Designer Asked To Improve Robo-Bugs 21

Posted by Soulskill from the can-you-make-them-super-robo-bugs? dept.
Nerval's Lobster writes "The man who designed the world's most energy-efficient supercomputer in 2011 has taken on a new task: improving how robo-bugs fly. Wu-chun Feng, an associate professor of computer science in the College of Engineering at Virginia Tech, previously built Green Destiny, a 240-node supercomputer that consumed 3.2 kilowatts of power—the equivalent of a couple of hair dryers. That was before the Green500, a list that Feng and his team began compiling in 2005, which ranks the world's fastest supercomputers by performance per watt. On Feb. 5, the Air Force's Office of Scientific Research announced it had awarded Feng $3.5 million over three years, plus an option to add $2.5 million funding over an additional two years. The contract's goal: speed up how quickly a supercomputer can simulate the computational fluid dynamics of micro-air vehicles (MAVs), or unmanned aerial vehicles. MAVs can be as small as about five inches, with an aircraft close to insect size expected in the near future. While the robo-bugs can obviously be used for military purposes, they could also serve as scouts in rescue operations."

Semi-Automatic Hacking of Masked ROM Code From Microscopic Images 42

Posted by Soulskill from the making-a-computer-read-a-computer dept.
An anonymous reader writes "Decapping chips and recovering code or data is nothing new, but the old problem of recovering Masked ROM through visual inspection (binary '0' and '1' can be distinguished within the images) is normally done by crowd sourcing a manual typing effort. Now a tool that semi-automates this process and then recovers the data automatically has been released."
