Seagate Ships First 8 Terabyte Hard Drive

slashdot.org - dc, 27/08/2014 - 03:01
MojoKid (1002251) writes Seagate announced today that it has begun shipping the world's first 8 Terabyte hard drive. The 8TB hard drive comes only five months after Western Digital released the first ever 6TB HDD. Up until then, Seagate's high capacity HDDs had been shipping only to select enterprise clients. The 8TB HDD comes in the 3.5-inch form factor and, according to the manufacturer, features a SATA 6Gbps interface and multi-drive RV tolerance which makes it suitable for data centers. It's unclear what technology the drive is based on, or if PMR (Perpendicular Magnetic Recording) or low-resistance helium technology was employed.

Comcast Tells Government That Its Data Caps Aren't Actually "Data Caps"

slashdot.org - dc, 27/08/2014 - 01:08
mpicpp (3454017) writes with this excerpt from Ars Technica about Comcast's data caps that aren't data caps:Customers must pay more if they exceed limits — but it's not a cap, Comcast says. For the past couple of years, Comcast has been trying to convince journalists and the general public that it doesn't impose any "data caps" on its Internet service. ... That's despite the fact that Comcast in some cities enforces limits on the amount of data customers can use and issues financial penalties for using more than the allotment. Comcast has said this type of billing will probably roll out to its entire national footprint within five years, perhaps alongside a pricier option to buy unlimited data. ... Comcast's then-new approach was touted to "effectively offer unlimited usage of our services because customers will have the ability to buy as much data as they want."

Project Zero Exploits 'Unexploitable' Glibc Bug

slashdot.org - dc, 27/08/2014 - 00:29
NotInHere (3654617) writes with news that Google's Project Zero has been busy at work. A month ago they reported an off-by-one error in glibc that would overwrite a word on the heap with NUL and were met with skepticism at its ability to be used in an attack. Google's 'Project Zero' devised an exploit of the out-of-bounds NUL write in glibc to gain root access using the setuid binary pkexec in order to convince skeptical glibc developers. 44 days after being reported, the bug has been fixed. They even managed to defeat address space randomization on 32-bit platforms by tweaking ulimits. 64-bit systems should remain safe if they are using address space randomization.

Exomoon Detection Technique Could Greatly Expand Potential Habitable Systems

slashdot.org - dm, 26/08/2014 - 23:48
Luminary Crush (109477) writes Most of the detected exoplanets thus far have been gas giants which aren't great candidates for life as we know it. However, many of those planets are in fact in the star's habitable zone and could have moons with conditions more favorable. Until now, methods to detect the moons of such gas giants have been elusive, but researchers at the University of Texas, Arlington have discovered a way to detect the interaction of a moon's ionosphere with the parent gas giant from studies of Jupiter's moon Io. The search for 'Pandora' has begun.

Free Law Casebook Project Starts With IP Coursebook

slashdot.org - dm, 26/08/2014 - 23:08
An anonymous reader writes Duke Law School's James Boyle and Jennifer Jenkins just published a CC licensed, freely downloadable textbook called "Intellectual Property Law and the Information Society." (Which includes a discussion of whether and when the term "intellectual property" is a dangerous misnomer). The book is apparently part of an attempt to lower what the authors describe as the "obscene cost" of legal textbooks. "This is the first in a series of free digital/low cost print legal educational materials to be published by Duke's Center for the Study of the Public Domain—starting with statutory supplements aimed at the basic classes. The goal of this project... is to improve the pricing and access norms of the world of legal textbook publishing, while offering the flexibility and possibility for customization that unfettered digital access provides. We hope it will provide a pleasant, restorative, competitive pressure on the commercial publishers to lower their prices and improve their digital access norms." The book's "problems range from a video of the Napster oral argument to counseling clients about search engines and trademarks, applying the First Amendment to digital rights management and copyright or commenting on the Supreme Court's new rulings on gene patents.. [The book] includes discussions of such issues as the Redskins trademark cancelations, the Google Books case and the America Invents Act."

Uber Has a Playbook For Sabotaging Lyft, Says Report

slashdot.org - dm, 26/08/2014 - 22:26
Nerval's Lobster (2598977) writes "The folks over at The Verge claim that 'Uber is arming teams of independent contractors with burner phones and credit cards as part of its sophisticated effort to undermine Lyft and other competitors.' Interviews and documents apparently show Uber reps ordering and canceling Lyft rides by the thousands, following a playbook with advice designed to prevent Lyft from flagging their accounts. 'Uber appears to be replicating its program across the country. One email obtained by The Verge links to an online form for requesting burner phones, credit cards, and driver kits — everything an Uber driver needs to get started, which recruiters often carry with them.' Is this an example of legal-but-hard-hitting business tactics, or is Uber overstepping its bounds? The so-called sharing economy seems just as cutthroat — if not more so — than any other industry out there."

The Grumpy Programmer has Advice for Young Computer Workers (Video)

slashdot.org - dm, 26/08/2014 - 21:45
Bob Pendleton calls his blog "The Grumpy Programmer" because he's both grumpy and a programmer. He's also over 60 years old and has been programming since he was in his teens. This pair of videos is a break from our recent spate of conference panels and corporate people. It's an old programmer sharing his career experiences with younger programmers so they (you?) can avoid making his mistakes and possibly avoid becoming as grumpy as he is -- which is kind of a joke, since Bob is not nearly as grumpy as he is light-hearted. (Transcript covers both videos. Alternate Video Link One; Alternate Video Link Two)

How the Ancient Egyptians (Should Have) Built the Pyramids

slashdot.org - dm, 26/08/2014 - 20:20
KentuckyFC writes The Great Pyramid of Giza in Egypt is constructed from 2.4 million limestone blocks, most about 2.5 tonnes but some weighing in at up to 80 tonnes, mostly sourced from local limestone quarries. That raises a famous question. How did the ancient Egyptians move these huge blocks into place? There is no shortage of theories but now a team of physicists has come up with another that is remarkably simple--convert the square cross section of the blocks into dodecadrons making them easy to roll. The team has tested the idea on a 30 kg scaled block the shape of a square prism. They modified the square cross-section by strapping three wooden rods to each long face, creating a dodecahedral profile. Finally, they attached a rope to the top of the block and measured the force necessary to set it rolling. The team say a full-sized block could be modified with poles the size of ships masts and that a work crew of around 50 men could move a block with a mass of 2.5 tonnes at the speed of 0.5 metres per second. The result suggests that this kind of block modification is a serious contender for the method the Egyptians actually used to construct the pyramids, say the researchers.

VMware Unveils Workplace Suite and NVIDIA Partnership For Chromebooks

slashdot.org - dm, 26/08/2014 - 19:38
Gamoid writes At VMworld today, VMware introduced the Workplace Suite, a platform for securely delivering applications and content across desktops and mobile devices from the cloud. The really cool part, though, is a partnership with Google and NVIDIA to deliver even graphics-intensive Windows applications on a Chromebook. From the article: "The new VMware Workplace Suite takes advantage of three existing VMware products: Tools for application, device, and content management as well as secure cloud file storage that comes from the January acquisition of enterprise mobile management company AirWatch; VMware Horizon for desktop-as-a-service; and brand-new acquisition CloudVolumes for app delivery.

Climate Scientist Pioneer Talks About the Furture of Geoengineering

slashdot.org - dm, 26/08/2014 - 18:56
First time accepted submitter merbs writes At the first major climate engineering conference, Stanford climatologist Ken Caldeira explains how and why we might come to live on a geoengineered planet, how the field is rapidly growing (and why that's dangerous), and what the odds are that humans will try to hijack the Earth's thermostat. From the article: "For years, Dr. Ken Caldeira's interest in planet hacking made him a curious outlier in his field. A highly respected atmospheric scientist, he also describes himself as a 'reluctant advocate' of researching solar geoengineering—that is, large-scale efforts to artificially manage the amount of sunlight entering the atmosphere, in order to cool off the globe."

California DMV Told Google Cars Still Need Steering Wheels

slashdot.org - dm, 26/08/2014 - 18:12
cartechboy writes Google showed us what it feels is the car of the future. It drives itself, it doesn't have a gas or brake pedal, and there's no steering wheel. But that last one might be an issue. Back in May California's Department of Motor Vehicles published safety guidelines aimed at manufacturers of self-driving vehicles. After seeing Google's self-driving car vision, the California DMV has told the company it needs to add all those things back to their traditional locations so that occupants can take "immediate physical control" of the vehicle if necessary. Don't for a second think this is a major setback for Google, as the prototypes unveiled weren't even close to production ready. While the DMV may loosen some of these restrictions in the future as well all become more comfortable with the idea of self-driving vehicles, there's no question when it comes down to the safety of those on the road.

TechCentral Scams Call Center Scammers

slashdot.org - dm, 26/08/2014 - 17:31
An anonymous reader writes "At TechCentral, we get on average called at least once a week — sometimes far more often — by a friendly sounding Indian national warning us that our Windows computer is infected with a virus. The call, which originates from a call centre, follows exactly the same script every time. Usually we shrug them off and put the phone down, but this week we thought we'd humour them to find out how they operate. As this week's call came in, the first thing the "operator" at the other end of the line tried to establish was who was owner of the Windows computer in the household. I'd taken the call. It was time to have some fun. I told the scammer that I was the PC owner. He proceeded to introduce himself as "John Connor." I laughed quietly as I imagined Arnold Schwarzenegger's Terminator hunting down this scamster in the streets of Calcutta. Perhaps he should have come up with a more convincing name."

IBM Gearing Up Mega Power 8 Servers For October Launch

slashdot.org - dm, 26/08/2014 - 16:49
darthcamaro (735685) writes "Now that IBM has sold off its x86 server business to Lenovo, it's full steam ahead for IBM's Power business. While Intel is ramping up its next generation of server silicon for a September launch, IBM has its next lineup of Power 8 servers set to be announced in October. "There is a larger than 4U, 2 socket system coming out," Doug Balog, General Manager of Power Systems within IBM's System and Technology Group said. Can IBM Power 8 actually take on x86? Or has that ship already sailed?" At last weekend's Linux Con in Chicago, IBM talked up the availability of the Power systems, and that they are working with several Linux vendors, including recently-added Ubuntu; watch for a video interview with Balog on how he's helping spend the billion dollars that IBM pledged last year on open source development.

New Windows Coming In Late September -- But Which One?

slashdot.org - dm, 26/08/2014 - 15:07
snydeq (1272828) writes "Nobody seems to know for sure whether 'Threshold' and 'Windows 9' will be one and the same or separate operating systems, reports Woody Leonhard in his roundup of insights on Microsoft's forthcoming OS plans, expected September 30. 'Many people think the terms are synonymous, but longtime Chinese leaker Faikee continues to maintain that they are two separate products, possibly headed in different directions. Neowin Senior Editor and Columnist Brad Sams appears to have access to the most recent test builds, possibly on a daily basis. He doesn't talk about details, but the items he's let drop on the Neowin forum leave an interesting trail of crumbs.' Either way, the next iteration of Windows will have a lot to say about the kind of Microsoft to expect as Satya Nadella cements his leadership over the flagship OS."

California Passes Law Mandating Smartphone Kill Switch

slashdot.org - dm, 26/08/2014 - 14:26
alphadogg (971356) writes "Smartphones sold in California will soon be required to have a kill switch that lets users remotely lock them and wipe them of data in the event they are lost or stolen. The demand is the result of a new law, http://www.leginfo.ca.gov/pub/... into effect on Monday, that applies to phones manufactured after July 1, 2015, and sold in the state. While its legal reach does not extend beyond the state's borders, the inefficiency of producing phones solely for California means the kill switch is expected to be adopted by phone makers on handsets sold across the U.S. and around the world."

$75K Prosthetic Arm Is Bricked When Paired iPod Is Stolen

slashdot.org - dm, 26/08/2014 - 13:44
kdataman writes U.S. Army Staff Sgt. Ben Eberle, who lost an arm and both legs in Afghanistan, had his Ipod Touch stolen on Friday. This particular Ipod Touch has an app on it that controls his $75,000 prosthetic arm. The robbery bricked his prosthesis: "That is because Eberle's prosthetic hand is programmed to only work with the stolen iPod, and vice versa. Now that the iPod is gone, he said he has to get a new hand and get it reprogrammed with his prosthesis." I see three possibilities: 1) The article is wrong, possibly to guilt the thief into returning the Ipod. 2) This is an incredibly bad design by Touch Bionics. Why would you make a $70,000 piece of equipment permanently dependent on a specific Ipod Touch? Ipods do fail or go missing. 3) This is an intentionally bad design to generate revenue. Maybe GM should do this with car keys? "Oops, lost the keys to the corvette. Better buy a new one."

Amazon To Buy Twitch For $970 Million

slashdot.org - dm, 26/08/2014 - 13:04
Dave Knott (2917251) writes Amazon has agreed to acquire the live game-streaming service Twitch for approximately $970 million in cash, a move that could help Amazon bolster its position in the fast-growing business of online gaming and give it technology to compete with video-streaming rivals Netflix and YouTube. The acquisition, which has been approved by Twitch's shareholders, is expected to be completed by the end of the year. Google had for some time been reported to have interest in acquiring Twitch, but those talks cooled in recent weeks. Google was unable to close the deal, said sources familiar with the talks, because it was concerned about potential antitrust issues that could have come with the acquisition.
