220TB Tapes Show Tape Storage Still Has a Long Future

Sat, 11/04/2015 - 2:32pm
alphadogg writes: IBM and Fujifilm have figured out how to fit 220TB of data on a standard-size tape that fits in your hand, flexing the technology's strengths as a long-term storage medium. The prototype Fujifilm tape and accompanying drive technology from IBM labs packs 88 times as much data onto a tape as industry-standard LTO-6 systems using the same size cartridge, IBM says. LTO6 tape can hold 2.5TB, uncompressed, on a cartridge about 4 by 4 inches across and 2 centimeters thick. The new technologies won't come out in products for several years.

Cannabis Smoking Makes Students Less Likely To Pass University Courses

Sat, 11/04/2015 - 1:29pm
Bruce66423 writes: A large scale European study shows that students who were unable to buy cannabis legally were 5% more likely to pass their University courses. Below-average students with no legal access to pot were 7.6% more likely to pass their courses, and the effect was five times more pronounced when dealing with courses involving math. One of the study's authors said, "We think this newfound effect on productivity from a change in legal access to cannabis is not negligible and should be, at least in the short run, politically relevant for any societal drug legalization and prohibition decision-making. In the bigger picture, our findings also indicate that soft drug consumption behavior is affected by their legal accessibility, which has not been causally demonstrated before. ... Considering the massive impact on cognitive performance high levels of THC have, I think it is reasonable to at least inform young users much more on consequences of consuming such products as compared with that of having a beer or pure vodka."

Being Overweight Reduces Dementia Risk

Sat, 11/04/2015 - 12:28pm
jones_supa writes Being overweight cuts the risk of dementia, according to the largest and most precise investigation into the relationship (abstract). The researchers were surprised by the findings, which run contrary to current health advice. The team at Oxon Epidemiology and the London School of Hygiene and Tropical Medicine analyzed medical records from 2 million people aged 55 on average, for up to two decades. Their most conservative analysis showed underweight people had a 39% greater risk of dementia compared with being a normal healthy weight. But those who were overweight had an 18% reduction in dementia, and the figure was 24% reduction for the obese. Any explanation for the protective effect is distinctly lacking. There are some ideas that vitamin D and E deficiencies contribute to dementia and they may be less common in those eating more. Be it any way, let's still not forget that heart disease, stroke, diabetes, some cancers and other diseases are all linked to a bigger waistline. Maybe being slightly overweight is the optimum to strike, if the recent study is to be followed.

After EFF Effort, Infamous "Podcasting Patent" Invalidated

Sat, 11/04/2015 - 9:49am
Ars Technica reports some good news on the YRO front. An excerpt: A year-and-a-half after the Electronic Frontier Foundation created a crowd-funded challenge to a patent being used to threaten podcasters, the patent has been invalidated. In late 2013, after small podcasters started getting threat letters from Personal Audio LLC, the EFF filed what's called an "inter partes review," or IPR, which allows anyone to challenge a patent at the US Patent and Trademark Office. The order issued today by the USPTO lays to rest the idea that Personal Audio or its founder, Jim Logan, are owed any money by podcasters because of US Patent No. 8,112,504, which describes a "system for disseminating media content representing episodes in a serialized sequence." The article points out, though, that the EFF warns Personal Audio LLC is seeking more patents on podcasting. Mentioned within: Adam Carolla's fight against these patents and our Q&A with Jim Logan.

Nokia Networks Demonstrates 5G Mobile Speeds Running At 10Gbps Via 73GHz

Sat, 11/04/2015 - 7:00am
Mark.JUK writes The Brooklyn 5G Summit appears to have provided a platform for Nokia Networks to demo a prototype of their future 5G (5th Generation) mobile network technology, which they claim can already deliver data speeds of 10 Gigabits per second using millimeter Wave (mmW) frequency bands of 73GHz. The demo also made use of 2×2 Multiple-Input and Multiple-Output (MIMO) links via single carrier Null Cyclic Prefix modulation and frame size of 100 micro seconds, although crucially no information about the distance of this demo transmission has been released and at 73GHz you'd need quite a dense network in order to overcome the problems of high frequency signal coverage and penetration.

Would-Be Bomber Arrested In Kansas; Planned Suicide Attack on Ft. Riley

Sat, 11/04/2015 - 4:11am
The Associated Press (as carried by the Boston Herald) reports that a 20-year old Topeka man has been arrested as he attempted to arm what he believed to be a thousand-pound bomb outside Ft. Riley, Kansas. John T. Booker Jr. is alleged to have planned an attack in conspiracy with others who were actually FBI agents; Booker's postings to Facebook in March 2014 about his desire to die as a martyr brought him to the FBI's attention, and the FBI sting operation which ended in his arrest began after these posts. Booker had been recruited by the U.S. Army in February of last year, but his enlistment was cancelled shortly thereafter.

Google Lollipop Bricking Nexus 5 and Nexus 7 Devices

Sat, 11/04/2015 - 1:31am
First time accepted submitter Zape (303550) writes The Lollipop update has turned sour for me and several other Nexus 7, Gen 2 (and Nexus 5) owners. It seems that I'm not alone in having my tablet boot to the Google Logo since a couple of days after updating to Android 5.0.2. Now Nexus 5 owners are reporting a reboot loop in Android 5.1. My device, like many others, is a couple of months out of warranty, but worked great until the latest OTA update from Google. They branded it, and they updated it, but Google claims it is between the buyers and ASUS, the manufacturer.

Massive Lincoln Archive Goes Live On 150th Anniversary of His Assassination

Sat, 11/04/2015 - 12:48am
Lucas123 writes The Lincoln Project, a joint digitization project sponsored by The University of Illinois and the Abraham Lincoln Association, has been identifying transcribing, annotating, and imaging all documents written by or to Abraham Lincoln during his lifetime. Those 100,000 or so documents are now online for the public to view. The documents cover three eras: Lincoln's time practicing law from 1836 to 1861; his personal life from birth in February, 1809 through March 3, 1861; and his time as president. The archive contains images of some of the most historically significant documents penned by Lincoln, such as one of the five original copies of the Gettysburg Address. It also contains more personal moments, such as a letter he wrote before he became president to an 11-year-old girl responding to her request that he grow a beard to hide his skinny face.

How Flight Tracking Works: a Global Network of Volunteers

Fri, 10/04/2015 - 11:52pm
An anonymous reader writes If a website can show the flight path and all those little yellow planes in real time, how can they not know where Malaysia Airlines flight MH370 went down? Answering that involves understanding a little about how flight-tracking sites work, where they get their data, and the limitations of existing technologies. It also involves appreciating a relatively new approach that the two large flight-tracking companies, Texas-based FlightAware and Sweden-based Flightradar24 are rushing to expand, a global sensor system known as ADS-B, which broadcasts updates of aircraft GPS data in real time. ADS-B is slowly superseding the ground-based radar systems that have been used for decades, becoming central not only to flight tracking but also to the future of flight safety. And it's powered, in part, by thousands of dedicated aviation hobbyists around the globe.
