Extreme Heat Knocks Out Internet In Australia

An anonymous reader writes with news that bad weather caused internet connectivity problems for users in Perth, Western Australia on Monday. But it wasn’t raging storms or lightning that caused this outage — it was extreme heat. Monday was the 6th hottest day on record for Perth, peaking around 44.4 C (111.9 F). Thousands of iiNet customers across Australia found themselves offline for about six and a half hours after the company shut down some of its systems at its Perth data center at about 4.30pm AEDST because of record breaking-temperatures. … “[W]e shut down our servers as a precautionary measure, ” an iiNet spokesman said late Monday night. “Although redundancy plans ensured over 98 per cent of customers remained unaffected, some customers experienced issues reconnecting to the internet.” … Users in Western Australia, NSW, Victoria and South Australia took to Twitter, Facebook and broadband forum Whirlpool to post their frustrations to the country’s second largest DSL internet service provider.

Google Researcher Publishes Unpatched Windows 8.1 Security Vulnerability

An anonymous reader writes “Google’s security research database has after a 90 day timeout automatically undisclosed a Windows 8.1 vulnerability which Microsoft hasn’t yet patched. By design the system call NtApphelpCacheControl() in ahcache.sys allows application compatibility data to be cached for quick reuse when new processes are created. A normal user can query the cache but cannot add new cached entries as the operation is restricted to administrators. This is checked in the function AhcVerifyAdminContext(). Long story short, the aforementioned function has a vulnerability where it doesn’t correctly check the impersonation token of the caller to determine if the user is an administrator. It hasn’t been fully verified if Windows 7 is vulnerable. For a passer-by it is also hard to tell whether Microsoft has even reviewed the issue reported by the Google researcher. The database has already one worried comment saying that automatically revealing a vulnerability just like that might be a bad idea.” Read more of this story at Slashdot.

Belize’s "Blue Hole" Reveals Clues To Maya’s Demise

An anonymous reader writes The collapse of the Mayan civilization has been a mystery for decades, but now new research suggests that the blue hole of Belize could provide an answer. Studying minerals from Belize’s famous underwater cave, researchers have discovered that an extreme drought occurred between AD 800 and AD 900, which is when the Mayan civilization collapsed. From the article: “Although the findings aren’t the first to tie a drought to the Mayan culture’s demise, the new results strengthen the case that dry periods were indeed the culprit. That’s because the data come from several spots in a region central to the Mayan heartland, said study co-author André Droxler, an Earth scientist at Rice University.” Read more of this story at Slashdot.

Human Eye’s Oscillation Rate Determines Smooth Frame Rate

jones_supa writes: It should be safe to conclude that humans can see frame rates greater than 24 fps. The next question is: why do movies at 48 fps look “video-y, ” and why do movies at 24 fps look “dreamy” and “cinematic.” Why are games more realistic at 60 fps than 30 fps? Simon Cooke from Microsoft (Xbox) Advanced Technology Group has an interesting theory to explain this all. Your eyes oscillate a tiny amount, ranging from 70 to 103 Hz (on average 83.68 Hz). So here’s the hypothesis: The ocular microtremors wiggle the retina, allowing it to sample at approximately 2x the resolution of the sensors. Showing someone pictures that vary at less than half the rate of the oscillation means we’re no longer receiving a signal that changes fast enough to allow the supersampling operation to happen. So we’re throwing away a lot of perceived-motion data, and a lot of detail as well. Some of the detail can be restored with temporal antialiasing and simulating real noise, but ideally Cooke suggests going with a high enough frame rate (over 43 fps) and if possible, a high resolution.

Feds Plan For 35 Agencies To Collect, Share, Use Health Records of Americans

cold fjord writes: The Weekly Standard reports, “This week, the Department of Health and Human Services (HHS) announced the release of the Federal Health IT Strategic Plan 2015-2020, which details the efforts of some 35 departments and agencies of the federal government and their roles in the plan to ‘advance the collection, sharing, and use of electronic health information to improve health care, individual and community health, and research.’ … Now that HHS has publicly released the Federal Health IT Strategic Plan, the agency is seeking the input from the public before implementation. The plan is subject to two-month period of public comment before finalization. The comment period runs through February 6, 2015.” Among the many agencies that will be sharing records besides Health and Human Services are: Department of Agriculture, Department of Defense, Department of Education, Department of Justice and Bureau of Prison, Department of Labor, Federal Communications Commission, Federal Trade Commission, National Aeronautics and Space Administration, Office of Personnel Management, National Institute of Standards and Technology.

High Temperature Superconductivity Record Smashed By Sulfur Hydride

KentuckyFC writes Physicists at the Max Planck Institute for Chemistry in Germany have measured sulfur hydride superconducting at 190 Kelvin or -83 degrees Centigrade, albeit at a pressure of 150 gigapascals, about the half that at the Earth’s core. If confirmed, that’s a significant improvement over the existing high pressure record of 164 kelvin. But that’s not why this breakthrough is so important. Until now, all known high temperature superconductors have been ceramic mixes of materials such as copper, oxygen lithium, and so on, in which physicists do not yet understand how superconductivity works. By contrast, sulfur hydride is a conventional superconductor that is described by the BCS theory of superconductivity first proposed in 1957 and now well understood. Most physicists had thought that BCS theory somehow forbids high temperature superconductivity–the current BCS record-holder is magnesium diboride, which superconducts at just 39 Kelvin. Sulfur hydride smashes this record and will focus attention on other hydrogen-bearing materials that might superconduct at even higher temperatures. The team behind this work point to fullerenes, aromatic hydrocarbons and graphane as potential targets. And they suggest that instead of using high pressures to initiate superconductivity, other techniques such as doping, might work instead. Read more of this story at Slashdot.

The Fastest Camera Ever Made Captures 100 Billion Frames Per Second

Jason Koebler writes A new imaging technique is able to capture images at 100 billion frames per second—fast enough to watch light interact with objects, which could eventually lead to new cloaking technologies. The camera was developed by a team at Washington University in St. Louis—for the team’s first tests, it was able to visualize laser pulse reflections, photons racing through air and through resin, and “faster-than-light propagation of non-information.” It can also be used in conjunction with telescopes and to image optical and quantum communications, according to lead researcher Liang Gao.

IoT Is the Third Big Technology ‘Wave’ In the Last 50 Years, Says Harvard

dcblogs writes: The Internet of Things (IoT) may be more significant in reshaping the competitive landscape than the arrival of the Internet. Its productivity potential is so powerful it will deliver a new era of prosperity. That’s the argument put forth by Michael Porter, an economist at the Harvard Business School and James Heppelmann, president and CEO of PTC, in a recent Harvard Business Review essay. PTC is a product design software firm that recently acquired machine-to-machine firm Axeda Corp. In the past 50 years, IT has delivered two major transformations or “waves, ” as the authors describe it. The first came in the 1960s and 1970s, with IT-enabled process automation, computer-aided design and manufacturing resource planning. The second was the Internet and everything it delivered. The third is IoT. That’s a strikingly sweeping claim and there will no doubt be contrarians to Porter and Heppelmann’s view. But what analysts are clear about is that IoT development today is at an early stage, perhaps at a point similar to 1995, the same year Amazon and eBay went online, followed by Netflix in 1997 and Google in 1998. People understood the trend at the time, but the big picture was still out of focus. Read more of this story at Slashdot.
