Riecoin Breaks World Record For Largest Prime Sextuplet, Twice 18

Posted by timothy
from the well-the-sextuplet-was-just-sitting-there dept.
An anonymous reader writes Last week, Riecoin – a project that doubles as decentralized virtual currency and a distributed computing system — quietly broke the record for the largest prime number sextuplet. This happened on November 17, 2014 at 19:50 GMT and the calculation took only 70 minutes using the massive distributed computing power of its network. This week the feat was outdone and the project beat its own record on November 24, 2014 at 20:28 GMT achieving numbers 654 digits long, 21 more than its previous record.

Edsac Goes Live, At UK's National Museum of Computing 19

Rambo Tribble (1273454) writes "Britain's National Museum of Computing has flipped the switch on the venerable Edsac computer. The arduous task of reconstructing the 1949 behemoth, fraught with little in terms of the original hardware or documentation, was brought to fruition on Wednesday. As project lead, Andrew Herbert, is quoted as saying, "We face the same challenges as those remarkable pioneers who succeeded in building a machine that transformed computing." A remarkably shaky video of the event, replete with excellent views of the floor at the videographer's feet, can be found here."

Uber's Android App Caught Reporting Data Back Without Permission 130

Posted by timothy
from the distinguish-from-government dept.
Zothecula writes Security researcher GironSec has pulled Uber's Android app apart and discovered that it's sending a huge amount of personal data back to base – including your call logs, what apps you've got installed, whether your phone is vulnerable to certain malware, whether your phone is rooted, and your SMS and MMS logs, which it explicitly doesn't have permission to do. It's the latest in a series of big-time missteps for a company whose core business model is, frankly, illegal in most of its markets as well.

Google Told To Expand Right To Be Forgotten 93

Posted by timothy
from the what-about-the-right-to-remember? dept.
mpicpp writes with this news from the BBC: Google is under fresh pressure to expand the 'right to be forgotten' to its international .com search tool. A panel of EU data protection watchdogs said the move was necessary to prevent the law from being circumvented. Google currently de-lists results that appear in the European versions of its search engines, but not the international one. The panel said it would advise member states' data protection agencies of its view in new guidelines. However, a link is provided at the bottom right-hand corner of the screen offering an option to switch to the international .com version. This link does not appear if the users attempted to go to a regional version in the first place. Even so, it means it is possible for people in Europe to easily opt out of the censored lists.

jones_supa writes Windows Media Player is going to become a more useful media player for those who want to play geeky file formats. Microsoft has earlier confirmed that Windows 10 will come with native support for Matroska Video, but the company now talks about also adding FLAC support. Microsoft's Gabriel Aul posted a teaser screenshot in Twitter showing support for this particular format. It can be expected to arrive in a future update for people running the Windows 10 Technical Preview. Not many GUI changes seem to be happening around Media Player, but work is done under the hood.

Wikipedia's "Complicated" Relationship With Net Neutrality 79

Posted by samzenpus
from the playing-favorites dept.
HughPickens.com writes Brian Fung writes in the Washington Post that Wikipedia has been a little hesitant to weigh in on net neutrality, the idea that all Web traffic should be treated equally by Internet service providers such as Comcast or Time Warner Cable. That's because the folks behind Wikipedia actually see a non-neutral Internet as one way to spread information cheaply to users in developing countries. With Wikipedia Zero, users in places like Pakistan and Malaysia can browse the site without it counting it counting against the data caps on their cellphones or tablets. This preferential treatment for Wikipedia's site helps those who can't afford to pay for pricey data — but it sets the precedent for deals that cut against the net neutrality principle. "We believe in net neutrality in America," says Gayle Karen Young adding that Wikipedia Zero requires a different perspective elsewhere. "Partnering with telecom companies in the near term, it blurs the net neutrality line in those areas. It fulfills our overall mission, though, which is providing free knowledge."

Facebook and Google also operate programs internationally that are exempted from users' data caps — a tactic known somewhat cryptically as "zero rating". Facebook in particular has made "Facebook Zero" not just a sales pitch in developing markets but also part of an Internet.org initiative to expand access "to the two thirds of the world's population that doesn't have it." But a surprising decision in Chile shows what happens when policies of neutrality are applied without nuance. Chile recently put an end to the practice, widespread in developing countries, of big companies "zero-rating" access to their services. "That might seem perverse," says Glyn Moody, "since it means that Chilean mobile users must now pay to access those services, but it is nonetheless exactly what governments that have mandated net neutrality need to do."

Australia Elaborates On a New Drift Model To Find MH370 94

Posted by samzenpus
from the still-looking dept.
hcs_$reboot writes Malaysia Airlines Flight MH370 disappeared on Saturday, 8 March 2014, while flying from Malaysia to Beijing with 239 people on board. And 8 months later, after millions of dollars invested in a gigantic search operation, there is still no sign of the aircraft. Now, Australia is developing a new model to predict where the debris of the missing MH370 could wash up. Authorities had initially predicted that the plane's wreckage could drift and come ashore on Indonesia's West Sumatra island after about 4 months of Flight MH370's disappearance. "We are currently working... to see if we can get an updated drift model for a much wider area where there might be possibilities of debris washing ashore," search co-ordinator Peter Foley told reporters in Perth.

UK Announces Hybrid Work/Study Undergraduate Program To Fill Digital Gap 91

Posted by samzenpus
from the get-a-job dept.
An anonymous reader writes The UK's Digital Economy Minister Ed Vaizey today revealed a new scheme where undergraduates will be able to avoid student fees and student loans by working for companies for three years whilst simultaneously undertaking academic studies with participating universities, resulting in a degree at the end of their successful involvement in the scheme. The British government will fund two-thirds of the cost of tuition and the host employer the remainder. The "Digital Apprenticeship" scheme will remunerate students at an unspecified level of pay, and though details are currently sketchy, is reported to obviate the need for student loans. The initiative is targeting the skills gap in the digital sector, particularly in the field of web-development and technical analysis.

BT Blocking Private Torrent Sites? 66

Posted by samzenpus
from the no-site-for-you dept.
An anonymous reader writes This weekend both BT and Sky implemented the new changes, making it harder for their subscribers to reach these sites. Interestingly, however, BT appears to have gone above and beyond the court order, limiting access to various other sites as well. Over the past several days TorrentFreak has received reports from several users of private torrent sites who get an 'error blocked' message instead of their favorite sites. These include the popular IPTorrents.com and TorrentDay.com trackers, as well as scene release site Scnsrc.me. IPTorrents and Torrentday are significant targets. Although both sites require prospective users to obtain an invite from a current member (or from the site itself in exchange for cash), they have over a hundred thousand active users. The error displayed when BT subscribers try to access the above URLs is similar to that returned when users to try access sites covered by High Court injunctions.

Consortium Roadmap Shows 100TB Hard Drives Possible By 2025 157

Posted by samzenpus
from the in-the-future dept.
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 182

Posted by samzenpus
from the like-wildfire dept.
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? 123

Posted by samzenpus
from the eyes-have-it dept.
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 108

from the our-bad dept.
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 108

Posted by samzenpus
from the pulling-back-the-curtain dept.
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."
