Consortium Roadmap Shows 100TB Hard Drives Possible By 2025

Slashdot - 2 hours 15 min ago
Lucas123 writes An industry consortium made up by leading hard disk drive manufacturers shows they expect the areal density of platters to reach 10 terabits per square inch by 2025, which is more than 10 times what it is today. At that density, hard disk drives could conceivably hold up to 100TB of data. Key to achieving greater bit density is Heat-Assisted Magnetic Recording (HAMR) and Bit Patterned Media Recording (BPMR). While both HAMR and BPMR will increase density, the combination of both technologies in 2021 will drive it to the 10Tbpsi level, according to the Advanced Storage Technology Consortium (ASTC).

Health Advisor: Ebola Still Spreading, Worst Outbreak We've Ever Seen

Slashdot - 4 hours 25 min ago
Lasrick writes After four decades of confining Ebola outbreaks to small areas, experts acknowledged in an October 9 New England Journal of Medicine article that "we were wrong" about the scope of the current situation. At the present transmission rate, the number of Ebola cases in West Africa doubles every two to three weeks. Early diagnosis is the key to controlling the epidemic, but that's far easier said than done: "And there are several complicating factors. For one thing, the Centers for Disease Control and Prevention (CDC) estimate that 60 percent of all Ebola patients remain undiagnosed in their communities." A transmission rate below 1 is necessary to keep the outbreak under control (instead of the current rate of 1.5 to 2), and the authors detail what's in the works to help achieve early detection, which is crucial to reducing the current transmission rate.

Ask Slashdot: Best Biometric Authentication System?

Slashdot - 5 hours 12 min ago
kwelch007 writes I run a network for a company that does manufacturing primarily in a clean-room. We have many systems in place that track countless aspects of every step. However, we do not have systems in place to identify the specific user performing the step. I could do this easily, but asking users to input their AD login every time they perform a task is a time-waster (we have "shared" workstations throughout.) My question is, what technologies are people actually using successfully for rapid authentication? I've thought about fingerprint scanners, but they don't work because in the CR we have to wear gloves. So, I'm thinking either face-recognition or retinal scans...but am open to other ideas if they are commercially viable.

Voting Machines Malfunction: 5,000 Votes Not Counted In Kansas County

Slashdot - 5 hours 53 min ago
An anonymous reader writes A malfunction in electronic voting machines in Saline County, Kansas, left over 5,000 votes uncounted. That's roughly one-third of the votes cast. Counting those 5,207 votes didn't change any outcomes in this case however. “That’s a huge difference,” county Chairman Randy Duncan said when notified by the Journal of the error. “That’s scary. That makes me wonder about voting machines. Should we go back to paper ballots?”

Bitcoin Is Not Anonymous After All

Slashdot - 6 hours 36 min ago
Taco Cowboy points out a new study that shows it is possible to figure out the IP address of someone who pays for transactions anonymously online using bitcoins. "The Bitcoin system is not managed by a central authority, but relies on a peer-to-peer network on the Internet. Anyone can join the network as a user or provide computing capacity to process the transactions. In the network, the user's identity is hidden behind a cryptographic pseudonym, which can be changed as often as is wanted. Transactions are signed with this pseudonym and broadcast to the public network to verify their authenticity and attribute the Bitcoins to the new owner. In their new study, researchers at the Laboratory of Algorithmics, Cryptology and Security of the University of Luxembourg have shown that Bitcoin does not protect user's IP address and that it can be linked to the user's transactions in real-time. To find this out, a hacker would need only a few computers and about €1500 per month for server and traffic costs. Moreover, the popular anonymization network "Tor" can do little to guarantee Bitcoin user's anonymity, since it can be blocked easily."

BlackBerry Will Buy Your iPhone For $550

Slashdot - 7 hours 18 min ago
mpicpp points out that BlackBerry is hoping to get iPhone owners to switch to Passport smartphones by promising up to $550 to trade in their phones. "The promotion, which starts Monday, promises as much as $550 to iPhone owners who trade in their handsets in favor of BlackBerry's Passport. The actual trade-in value depends on the iPhone, with the iPhone 4S worth up to $90 and the iPhone 6 worth up to $400. (The iPhone 6 Plus is not eligible.) BlackBerry then sweetens the deal by kicking in an additional $150 as a topper for each iPhone. The deal will run through February 13, but it's good only in North America. Customers must buy the $599 to $699 unlocked Passport phone through either BlackBerry's website or Amazon. The trade-in amount comes in the form of a Visa prepaid card."

Jackie Chan Discs Help Boost Solar Panel Efficiency

Slashdot - 8 hours 2 min ago
wbr1 writes Apparently the pit pattern on a blu-ray disk is great at helping trap photons, rather than reflecting them. Applying this pattern to the glass in a solar panel can boost efficiency by 22%. Researchers at Northwestern tested this system with Jackie Chan discs. From the article: "To increase the efficiency of a solar panel by 22%, the researchers at Northwestern bought a copy of Police Story 3: Supercop on Blu-ray; removed the top plastic layer, exposing the recording medium beneath; cast a mold of the quasi-random pattern; and then used the mold to create a photovoltaic cell with the same pattern....The end result is a solar panel that has a quantum efficiency of around 40% — up about 22% from the non-patterned solar panel."

Fly With the Brooklyn Aerodrome (Video)

Slashdot - 8 hours 46 min ago
A bit of housing insulation material, a battery, a motor and propellor, a radio receiver and transmitter, and servos to control the motor and a pair of ailerons, and you're ready to fly the Brooklyn Aerodrome way. This isn't a tiny radio-controlled paper airplane, but a big bruiser with a 1:1 power to weight ratio (which means it can climb like a bat out of hell) and enough guts to fly in reasonably windy conditions while carrying a camera -- except we'd better not mention cameras, since Brooklyn Aerodrome creations, whether kits or plans, are obviously intended tohelp you build model airplanes, not drones. Timothy ran into project proponent Breck Baldwin at a maker faire near Atlanta, surrounded by a squadron of junior pilots who may someday become astronauts on the Moon - Mars run -- or at least delivery drone controllers for Amazon.
