Ask Slashdot: Linux-Friendly Desktop x86 Motherboard Manufacturers? 63

Posted by Soulskill
from the roll-your-own dept.
storkus writes: The release of Haswell-E and a price drop on Devil's Canyon has made me itch for a PC upgrade. However, looking around I discovered a pair of horror stories on Phoronix about the difficulties of using Linux on a multitude of motherboards. My question: if MSI, Gigabyte, Asus (and by extension Asrock) are out, who's left and are they any good? I'd like to build a (probably dual-boot, but don't know for sure) gaming and 'other' high-end machine with one of the above chips, so we're talking Z97 or X99; however, these stories seem to point to the problems being Windows-isms in the BIOS/UEFI structures rather than actual hardware incompatibility, combined with a lousy attitude (despite the Steam Linux distro being under development).

from the not-so-fast dept.
An anonymous reader writes "Anyone who might have been interested in the miniature Raspberry Pi compatible board mentioned here a month ago should know the board has been cancelled due to problems sourcing the Broadcom SoC. Given the less than welcoming response from the rpi community to the board's release, there is speculation as to why Hardkernel is having trouble buying the chip.

Reformatting a Machine 125 Million Miles Away 153

An anonymous reader writes: NASA's Opportunity rover has been rolling around the surface of Mars for over 10 years. It's still performing scientific observations, but the mission team has been dealing with a problem: the rover keeps rebooting. It's happened a dozen times this month, and the process is a bit more involved than rebooting a typical computer. It takes a day or two to get back into operation every time. To try and fix this, the Opportunity team is planning a tricky operation: reformatting the flash memory from 125 million miles away. "Preparations include downloading to Earth all useful data remaining in the flash memory and switching the rover to an operating mode that does not use flash memory. Also, the team is restructuring the rover's communication sessions to use a slower data rate, which may add resilience in case of a reset during these preparations." The team suspects some of the flash memory cells are simply wearing out. The reformat operation is scheduled for some time in September.

An anonymous reader writes The PHP team has announced the release of PHP 5.6.0. New features include constant scalar expressions, exponentiation using the ** operator, function and constant importing with the use keyword, support for file uploads larger than 2 GB, and phpdbg as an interactive integrated debugger SAPI. The team also notes important changes affecting compatibility. For example: "Array keys won't be overwritten when defining an array as a property of a class via an array literal," json_decode() is now more strict at parsing JSON syntax, and GMP resources are now objects. Here is the migration guide, the full change log, and the downloads page.

from the first-they-commission-a-story-about-you dept.
First time accepted submitter Nikkos (544004) writes Digital currency news website HashReport broke the news Monday that European megabank Santander has commissioned a study to "Analyze the impact of bitcoin and other cryptocurrencies on banks and devise a strategic course of action." The study is being facilitated as a challenge through Yegii, an 'Insight Network' founded by Trond Undheim. Undheim is also a Senior Lecturer at MIT Sloan School of Management, as well as Managing Director at Tautec Consulting. The challenge was initiated by Julio Faura — Head of Corporate development for Banco Santander. According to Dr. Undheim, Faura was "looking for additional outside perspective onto the topic of Bitcoin. While acquiring consulting services from top tier consulting firms can be exciting, he thought that an outsider, multidisciplinary perspective, would be particularly helpful."

from the need-gravity-to-balance-eye-fusion dept.
SternisheFan sends this report from Universe Today: How does microgravity affect your health? One of the chief concerns of NASA astronauts these days is changes to eyesight. Some people come back from long-duration stays in space with what appears to be permanent changes, such as requiring glasses when previously they did not. And the numbers are interesting. A few months after NASA [said] 20% of astronauts may face this problem, a new study points out that 21 U.S. astronauts that have flown on the International Space Station for long flights (which tend to be five to six months) face visual problems. These include "hyperopic shift, scotoma and choroidal folds to cotton wool spots, optic nerve sheath distension, globe flattening and edema of the optic nerve," states the University of Houston, which is collaborating with NASA on a long-term study of astronauts while they're in orbit.

Exomoon Detection Technique Could Greatly Expand Potential Habitable Systems 66

from the larry-ellison-to-buy-exomoon dept.
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.

Slashdot Asks: How Prepared Are You For an Earthquake? 191

Posted by timothy
from the hey-man-what's-the-exoskeleton-for? dept.
With three earthquakes of some significance in the news this weekend (Chile, California, and Iceland), it seems a good time to ask: If you live in an area of seismic danger, how are you prepared for an earthquake (or tsunami, mudslide, or other associated danger) and how prepared are you? Do you have a stash of emergency supplies, and if so, how did you formulate it? In the U.S. alone, it's surprising how many areas there are with some reasonable chance of earthquakes, though only a few of them are actually famous for it — and those areas are the ones where everything from building codes to cultural awareness helps mitigate the risks. I'm not sure I'd want to be in a skyscraper in Memphis or St. Louis during a replay of the New Madrid quakes of 1811-1812, which is probably worth worrying about for those in the region. Beyond personal safety, do you have a plan for your electronics and data if the earth starts shaking?

If Java Wasn't Cool 10 Years Ago, What About Now? 508

Posted by timothy
from the pretty-good-drink-especially-with-honey-and-cream dept.
10 years ago today on this site, readers answered the question "Why is Java considered un-cool?" 10 years later, Java might not be hip, but it's certainly stuck around. (For slightly more than 10 years, it's been the basis of the Advanced Placement test for computer science, too, which means that lots of American students are exposed to Java as their first formally taught language.) And for most of that time, it's been (almost entirely) Free, open source software, despite some grumbling from Oracle. How do you see Java in 2014? Are the pessimists right?

Magnitude 6.0 Quake Hits Northern California, Causing Injuries and Outages 135

Posted by timothy
from the be-safe-out-there dept.
As numerous sources report, an earthquake of magnitude 6.0 struck California early Sunday morning, with an epicenter about 9 miles south of Napa. According to the San Francisco Chronicle's account, Some power lines down in western Contra Costa County, but Bay Area bridges appeared to be fine, according to the California Highway Patrol. There were widespread reports of power outages, gas leaks and flooding in the North Bay, with at least 15,000 Pacific Gas and Electric Co. customers without power in Vallejo, Napa, Rohnert Park, Santa Rosa and Sonoma. Police reminded motorists to stop at darkened intersections. ... In Benicia, several miles from the epicenter, the quake was strong enough to knock pictures off mantles. Bay Area bridges appear to have survived the quake -- significant, in that the L.A. Times reports that USGS estimates peg it as "the largest earthquake to strike the Bay Area since the Loma Prieta temblor of 1989," and says that injury reports (especially from glass) are streaming in from the area around Napa. The Times also has a larger estimate of customers suffering power outages: "more than 42,000" around the northern Bay Area. Unsurprisingly, social media channels are full of pictures showing some of the damage.

For those in California, did you feel the quake? (And from how far away?) Update: 08/24 13:15 GMT by T : Also in earthquake news: an even stronger quake (magnitude 6.4) on Saturday struck central Chile, shaking Santiago -- nearly 70 miles from the epicenter -- for more than half a minute, but with "no immediate reports of fatalities or serious damage."

Securing Networks In the Internet of Things Era 106

from the glad-that-someone-finally-invented-things dept.
An anonymous reader writes "Gartner reckons that the number of connected devices will hit 26 billion by 2020, almost 30 times the number of devices connected to the IoT in 2009. This estimate doesn't even include connected PCs, tablets and smartphones. The IoT will represent the biggest change to our relationship with the Internet since its inception. Many IoT devices themselves suffer from security limitations as a result of their minimal computing capabilities. For instance, the majority don't support sufficiently robust mechanisms for authentication, leaving network admins with only weak alternatives or sometimes no alternatives at all. As a result, it can be difficult for organizations to provide secure network access for certain IoT devices."

A Movie of Triton Made From Voyager 2's Fly-by 25 Years Ago 34

Posted by Soulskill
from the pretty-pictures dept.
schwit1 writes: Using restored images taken by Voyager 2 when it flew past Neptune's moon Triton 25 years ago, scientists have produced a new map and flyby movie of the moon. "The new Triton map has a resolution of 1,970 feet (600 meters) per pixel. The colors have been enhanced to bring out contrast but are a close approximation to Triton's natural colors. Voyager's "eyes" saw in colors slightly different from human eyes, and this map was produced using orange, green and blue filter images. ... Although Triton is a moon of a planet and Pluto is a dwarf planet, Triton serves as a preview of sorts for the upcoming Pluto encounter. Although both bodies originated in the outer solar system, Triton was captured by Neptune and has undergone a radically different thermal history than Pluto. Tidal heating has likely melted the interior of Triton, producing the volcanoes, fractures and other geological features that Voyager saw on that bitterly cold, icy surface. Pluto is unlikely to be a copy of Triton, but some of the same types of features may be present." Dr. Paul Schenk provides provides further information on his blog, and the movie can be viewed here.

An anonymous reader writes Consumers are inadvertently leaving back doors open to attackers as they share login details and sign up for automatic log on to mobile apps and services, according to new research by Intercede. While 52% of respondents stated that security was a top priority when choosing a mobile device, 51% are putting their personal data at risk by sharing usernames and passwords with friends, family and colleagues. The research revealed that consumers are not only sharing passwords but also potentially putting their personal and sensitive information at risk by leaving themselves logged in to applications on their mobile devices, with over half of those using social media applications and email admitting that they leave themselves logged in on their mobile device.

YouTube Music Subscription Details Leak 71

Posted by Soulskill
from the hitting-some-of-the-right-notes dept.
Several readers sent word that Android Police has leaked details about YouTube's upcoming subscription service, Music Key. The benefits for users will include ad-free music, offline playback, and audio-only streams. It's expected to cost $10 per month. "Of course, one of Music Key's major value propositions is that users will have access not just to official discographies, but to concert footage, covers, and remixes. Play Music already houses some remixes and covers, but YouTube as a platform is significantly more open and workable for derivative content — the platform is much easier to add content to, and user discoverability is substantially different from Play Music." Others note Google still has to negotiate terms with many independent musicians, who could subsequently see their work blocked if they aren't willing to play by Google's rules.

C++14 is mostly an incremental update over C++11 with some new features like function return type deduction, variable templates, binary literals, generic lambdas, and so on. The official C++14 specification release will arrive later in the year, but for now Wikipedia serves as a good overview of the feature set."

Research Unveils Improved Method To Let Computers Know You Are Human 91

Posted by Unknown Lamer
from the until-computers-improve dept.
An anonymous reader writes CAPTCHA services that require users to recognize and type in static distorted characters may be a method of the past, according to studies published by researchers at the University of Alabama at Birmingham. Researchers focused on a broad form of gamelike CAPTCHAs, called dynamic cognitive game, or DCG, CAPTCHAs, which challenge the user to perform a gamelike cognitive task interacting with a series of dynamic images. For example, in a "ship parking" DCG challenge, the user is required to identify the boat from a set of moving objects and drag-and-drop it to the available "dock" location. The puzzle is easy for the human user to solve, but may be difficult for a computer program to figure out. The game-like nature may make the process more engaging for the user compared to conventional text-based CAPTCHAs. There are a couple research papers available: "A Three-Way Investigation of a Game-CAPTCHA: Automated Attacks, Relay Attacks and Usability" and "Dynamic Cognitive Game CAPTCHA Usability and Detection of Streaming-Based Farming."

from the keeping-it-cool dept.
1sockchuck writes In a unique approach to data center design, the new high-performance computing center in Oregon is housed in a geodesic dome. The new facility at the Oregon Health and Science University requires no mechanical air conditioning, using outside air to racks of servers reaching densities of 25kW per cabinet. The design uses an aisle containment system to separate hot and cold air, and can recirculate server exhaust heat to adjust cold aisle temperatures in the winter. It's a very cool integration of many recent advances in data center design, combining elements of the Yahoo Chicken Coop and server silo in Quebec. The school has posted a virtual tour that provides a deep technical dive.

stephendavion writes Looks like Chinese device maker, Xiaomi, is taking its "Apple of the East" tag too literally. First, their CEO brazenly copies Steve Jobs' signature look, sitting cross-legged on the floor. And now, Xiaomi's latest version of Android shamelessly rips off iOS 7. MIUI 6, which is Xiaomi's upcoming edition of Android for its latest phones and tablets, looks almost exactly like Apple's operating system for iPhones, iPads and the iPod Touch. It features the same bright color palette and a flat design. Heck, it even does away with Google's "app drawer" and puts all apps on your home screen. It's like the CEO handed iPhones to the design team and barked: "Here, copy this!"

Fukushima's Biological Legacy 116

Posted by Soulskill
from the please-be-mothra-please-be-mothra dept.
An anonymous reader sends this report from Eurekalert: Scientists began gathering biological information only a few months after the disastrous 2011 meltdown of the Fukushima power plant in Japan. Results of these studies are now beginning to reveal serious biological effects of the Fukushima radiation on non-human organisms ranging from plants to butterflies to birds. A series of articles summarizing these studies has been published in the Journal of Heredity describing impacts ranging from population declines to genetic damage (abstract 1, abstract 2, abstract 3, abstract 4). Most importantly, these studies supply a baseline for future research on the effects of ionizing radiation exposure to the environment. Common to all of the published studies is the hypothesis that chronic (low-dose) exposure to ionizing radiation results in genetic damage and increased mutation rates in reproductive and non-reproductive cells. Meanwhile, efforts to restart Japan's nuclear power program are dead in the water.
