Operation Wants To Mine 10% of All New Bitcoins

An anonymous reader writes: “Mining new Bitcoins is computationally expensive — you can’t expect to do much on your standard home computer. Many miners have built custom rigs to mine more efficiently, but it was only a matter of time until somebody went industrial. Dave Carlson’s goal is to mine 10% of all new Bitcoins from now on. He’s built literally thousands of units. They collectively use 1.4 million BitFury mining chips, which are managed by a bunch of Raspberry Pis. ‘The current rigs each contain 16 boards, with each board containing 16 BitFury chips, for a total of 256 mining chips on each rig. Carlson said about 90, 000 processor boards have been deployed, which would put the number of rigs at about 5, 600. A new board [being designed] will have 756 chips on each rig instead of 256.’ Carlson says his company spent $3-5 million to get everything set up. They current generate 7, 000 — 8, 000 Bitcoins per month, which, at current rates, would be worth over $4 million.” Read more of this story at Slashdot.

Homeopathic Remedies Recalled For Containing Real Medicine

ananyo (2519492) writes “The U.S. Food and Drug Administration (FDA) has recalled homeopathic remedies made by a company called Terra-Medica because they may contain actual medicine — possibly penicillin or derivatives of the antibiotic.” Diluted enough times with pure water, though, maybe these traces would be even more powerful.

Mazda Says Its Upcoming Gas-Powered Cars Will Emit Less CO2 Than Electric Cars

cartechboy writes: “One of the arguments for electric cars is that we are reducing greenhouse gases and emitting less CO2 than vehicles with an internal combustion engine. But Mazda says its next-generation SkyActiv engines will be so efficient, they’ll emit less CO2 than an electric car. In fact, the automaker goes so far as to say these new engines will be cleaner to run than electric cars. Is it possible? Yes, but it’s all about the details. It’ll depend on the test cycles for each region. Vehicles are tested differently in Europe than in the U.S., and that variation could make all the difference when it comes to these types of claims. At the end of the day whether future Mazdas with gasoline-powered engines are cleaner than electric cars or not, every little bit in the effort to reduce our carbon emissions per mile is a step in the right direction, right?” Read more of this story at Slashdot.

NVIDIA Unveils Next Gen Pascal GPU With Stacked 3D DRAM and GeForce GTX Titan Z

MojoKid (1002251) writes “NVIDIA’s 2014 GTC (GPU Technology Conference) kicked off today in San Jose California, with NVIDIA CEO Jen-Hsun Huang offering up a healthy dose of new information on next generation NVIDIA GPU technologies. Two new NVIDIA innovations will be employed in their next-gen GPU technology, now know by its code named ‘Pascal.” First, there’s a new serial interconnect known as NVLink for GPU-to-CPU and GPU-to-GPU communication. Though details were sparse, apparently NVLink is a serial interconnect that employs differential signaling with embedded clock and it allows for unified memory architectures and eventually cache coherency. It’s similar to PCI Express in terms of command set and programming model but NVLink will offer a massive 5 — 12X boost in bandwidth up to 80GB/sec. The second technology to power NVIDIA’s forthcoming Pascal GPU is 3D stacked DRAM technology.The technique employs through-silicon vias that allow the ability to stack DRAM die on top of each other and thus provide much more density in the same PCB footprint for the DRAM package. Jen-Hsun also used his opening keynote to show off NVIDIA’s most powerful graphics card to date, the absolutely monstrous GeForce GTX Titan Z. The upcoming GeForce GTX Titan Z is powered by a pair of GK110 GPUs, the same chips that power the GeForce GTX Titan Black and GTX 780 Ti. All told, the card features 5, 760 CUDA cores (2, 880 per GPU) and 12GB of frame buffer memory—6GB per GPU. NVIDIA also said that the Titan Z’s GPUs are tuned to run at the same clock speed, and feature dynamic power balancing so neither GPU creates a performance bottleneck.” Read more of this story at Slashdot.

Is DIY Brainhacking Safe?

An anonymous reader writes “My colleague at IEEE Spectrum, Eliza Strickland, looked at the home transcranial direct current stimulation (tDCS) movement. People looking to boost creativity, or cure depression, are attaching electrodes to their heads using either DIT equipment or rigs from vendors like Foc.us. Advocates believe experimenting with the tech is safe, but a neuroscientist worries about removing the tech from lab safeguards…” Read more of this story at Slashdot.

Weak Apple PRNG Threatens iOS Exploit Mitigations

Trailrunner7 writes “A revamped early random number generator in iOS 7 is weaker than its vulnerable predecessor and generates predictable outcomes. A researcher today at CanSecWest said an attacker could brute force the Early Random PRNG used by Apple in its mobile operating system to bypass a number of kernel exploit mitigations native to iOS. ‘The Early Random PRNG in iOS 7 is surprisingly weak, ‘ said Tarjei Mandt senior security researcher at Azimuth Security. ‘The one in iOS 6 is better because this one is deterministic and trivial to brute force.’ The Early Random PRNG is important to securing the mitigations used by the iOS kernel. ‘All the mitigations deployed by the iOS kernel essentially depend on the robustness of the Early Random PRNG, ‘ Mandt said. ‘It must provide sufficient entropy and non-predictable output.'” Read more of this story at Slashdot.

XKCD Author’s Unpublished Book Has Already Become a Best-Seller

destinyland writes “Wednesday the geeky cartoonist behind XKCD announced that he’d publish a new book answering hypothetical science questions in September. And within 24 hours, his as-yet-unpublished work had become Amazon’s #2 best-selling book. ‘Ironically, this book is titled What If?, ‘ jokes one blogger, noting it resembles an XKCD comic where ‘In our yet-to-happen future, this book decides to travel backwards through time, stopping off in March of 2014 to inform Amazon’s best-seller list that yes, in our coming timeline this book will be widely read…’ Randall Munroe’s new book will be collecting his favorite ‘What If…’ questions, but will also contain his never-before published answers to some questions that he’d found ‘particularly neat.'” Read more of this story at Slashdot.

Nanomaterial May Be Future of Hard Drives

sciencehabit writes “Most magnets shrug off tiny temperature tweaks. But now physicists have created a new nanomaterial–an ultrathin 10-nanometer layer of nickel grafted onto a 100-nanometer-thick wafer of a substance called vanadium oxide–that dramatically changes how easily it flips its magnetic orientation when heated or cooled only slightly. The effect, never before seen in any material, could eventually lead to new types of computer memory.” Read more of this story at Slashdot.

Vast Surveillance Network Powered By Repo Men

v3rgEz writes “Even as some police departments curtail their sue of license plate scanning technology over privacy concerns, private companies have been amassing a much larger, almost completely unregulated database that pulls in billions of scans a year, marking the exact time and location of millions of vehicles across America. The database, which is often offered to law enforcement for free, is collected by repo and towing companies eager to tap easy revenue, while the database companies then resell that data, often for as little as $25 for a plate’s complete recorded history.” Read more of this story at Slashdot.
