+ - Linux 4,0 Getting No-Reboot Patching->

Submitted by Anonymous Coward
An anonymous reader writes "ZDNet reports that the latest changes to the Linux kernel include the ability to apply patches without requiring a reboot. From the article: "So, Red Hat and SUSE both started working on their own purely open-source means of giving Linux the ability to keep running even while critical patches were being installed. Red Hat's program was named kpatch, while SUSE' is named kGraft. ... At the Linux Plumbers Conference in October 2014, the two groups got together and started work on a way to patch Linux without rebooting that combines the best of both programs. Essentially, what they ended up doing was putting both kpatch and kGraft in the 4.0 Linux kernel." Note: "Simply having the code in there is just the start. Your Linux distribution will have to support it with patches that can make use of it.""

+ - Treadmill Performance Predicts Mortality->

Submitted by Anonymous Coward
An anonymous reader writes "Cardiologists from Johns Hopkins have published an analysis of exercise data that strongly links a patient's performance on a treadmill to their risk of dying. Using data from stress tests of over 58,000 people, they report: "[A]mong people of the same age and gender, fitness level as measured by METs and peak heart rate reached during exercise were the greatest indicators of death risk. Fitness level was the single most powerful predictor of death and survival, even after researchers accounted for other important variables such as diabetes and family history of premature death — a finding that underscores the profound importance of heart and lung fitness, the investigators say." The scoring system is from -200 to +200. People scoring between -100 and 0 face an 11% risk of dying in the next decade. People scoring between -200 and -100 face a 38% risk of death within the next decade. People scoring above zero face only a 3% of less chance."

+ - Technology's Legacy: The 'Loser Edit' Awaits Us All->

Submitted by Anonymous Coward
An anonymous reader writes "The NY Times Magazine has an insightful article putting into words how I've felt about information-age culture for a while now. It's about a phenomenon dubbed the "loser edit." The term itself was borne out of reality TV — once an outcome had been decided, the show's producers would comb back through the footage and selectively paste together everything that seemed to foreshadow the loser's fall.

But as the information age has overtaken us, this is something that can happen to anyone. Any time a celebrity gets into trouble, we can immediately search through two decades of interviews and offhand comments to see if there were hints of their impending fall. It usually becomes a self-reinforcing chain of evidence. The loser edit happens for non-celebrities too, using their social media posts, public records, leaked private records, and anything else available through search.

The worst part is, there's no central place to blame. The news media does it, the entertainment industry does it, and we do it to ourselves. Any time the internet gets outraged about something, there are a few people who happily dig up everything they can about the person they now feel justified in hating — and thus, the loser edit begins."

Has the Supreme Court Made Patent Reform Legislation Unnecessary? 38

Posted by Soulskill
from the reply-hazy-try-again dept.
An anonymous reader writes: As Congress gears up again to seriously consider patent litigation abuse—starting with the introduction of H.R. 9 (the "Innovation Act") last month—opponents of reform are arguing that recent Supreme Court cases have addressed concerns. Give the decisions time to work their way through the system, they assert. A recent hearing on the subject before a U.S. House Judiciary Committee (HJC) Subcommittee shined some light on the matter. And, as HJC Chairman Bob Goodlatte, a long-time leader in Internet and intellectual property issues, put it succinctly in his opening remarks: "We've heard this before, and though I believe that the Court has taken several positive steps in the right direction, their decisions can't take the place of a clear, updated and modernized statute. In fact, many of the provisions in the Innovation Act do not necessarily lend themselves to being solved by case law, but by actual law—Congressional legislation."

GitLab Acquires Gitorious 23

Posted by Soulskill
from the git-together dept.
New submitter sckirklan writes with news that code repository GitLab has purchased rival service Gitorious. Gitorious users are now able to import their projects into GitLab. They must do so by the end of May, because Gitorious will shut down on June 1st. Rolf Bjaanes, Gitorious CEO, gives some background on the reasons for the acquisition: “At Gitorious we saw more and more organizations adopting GitLab. Due to decreased income from on-premises customers, running the free Gitorious.org was no longer sustainable. GitLab was solving the same problem that we were, but was solving it better.” “This acquisition will accelerate the growth of GitLab. With more than 100,000 organizations using it, it is already the most used on-premise solution for Git repository management, and bringing Gitorious into the fold will significantly increase that footprint.” says Sytse Sijbrandij, GitLab CEO.

AMD Enters Virtual Reality Fray With LiquidVR SDK At GDC 12

Posted by Soulskill
from the buzzword-ascending dept.
MojoKid writes: AMD jumped into the virtual reality arena today by announcing that its new LiquidVR SDK will help developers customize VR content for AMD hardware. "The upcoming LiquidVR SDK makes a number of technologies available which help address obstacles in content, comfort and compatibility that together take the industry a major step closer to true, life-like presence across all VR games, applications, and experiences," AMD representatives said in a statement. Oculus is one of the VR companies that will be working with AMD's LiquidVR SDK, and likes what it's seen so far. "Achieving presence in a virtual world continues to be one of the most important elements to delivering amazing VR," said Brendan Iribe, CEO of Oculus. "We're excited to have AMD working with us on their part of the latency equation, introducing support for new features like asynchronous timewarp and late latching, and compatibility improvements that ensure that Oculus' users have a great experience on AMD hardware."

Study: Refactoring Doesn't Improve Code Quality 132

Posted by Soulskill
from the just-makes-you-hate-it-a-bit-less dept.
itwbennett writes: A team of researchers in Sri Lanka set out to test whether common refactoring techniques resulted in measurable improvements in software quality, both externally (e.g., Is the code more maintainable?) and internally (e.g., Number of lines of code). Here's the short version of their findings: Refactoring doesn't make code easier to analyze or change (PDF); it doesn't make code run faster; and it doesn't result in lower resource utilization. But it may make code more maintainable.

Former MLB Pitcher Doxes Internet Trolls, Delivers Real-World Consequences 201

Posted by Soulskill
from the countering-free-speech-with-more-free-speech dept.
An anonymous reader writes: When Twitter trolls began posting obscene, sexually explicit comments about his teenage daughter, former MLB pitcher Curt Schilling responded by recording their comments and gathering personal information readily available to the public. He then doxxed two of them on his blog, resulting in one being suspended from his community college and the other being fired from his part-time job as a ticket seller for the New York Yankees. There were seven others in Curt's crosshairs, all college athletes, but although he hasn't publicly doxxed those individuals, he hints, "I found it rather funny at how quickly tone changed when I heard via email from a few athletes who'd been suspended by their coaches. Gone was the tough guy tweeter, replaced by the 'I'm so sorry' apology used by those only sorry because they got caught."

+ - White House issues veto threat as House prepares to vote on EPA 'secret science'->

Submitted by sciencehabit
sciencehabit (1205606) writes "The U.S. House of Representatives could vote as early as this week to approve two controversial, Republican-backed bills that would change how the U.S. Environmental Protection Agency (EPA) uses science and scientific advice to inform its policies. Many Democrats, scientific organizations, and environmental groups are pushing back, calling the bills thinly veiled attempts to weaken future regulations and favor industry. White House advisors today announced that they will recommend that President Barack Obama veto the bills if they reach his desk in their current form."

Physicists Gear Up To Catch a Gravitational Wave 78

Posted by Soulskill
from the surf's-up dept.
sciencehabit writes: A patch of woodland just north of Livingston, Louisiana, population 1893, isn't the first place you'd go looking for a breakthrough in physics. Yet it is here that physicists may fulfill perhaps the most spectacular prediction of Albert Einstein's theory of gravity, or general relativity. Structures here house the Laser Interferometer Gravitational-Wave Observatory (LIGO), an ultrasensitive instrument that may soon detect ripples in space and time set off when neutron stars or black holes merge. Einstein himself predicted the existence of such gravitational waves nearly a century ago. But only now is the quest to detect them coming to a culmination. Physicists are finishing a $205 million rebuild of the detectors, known as Advanced LIGO, which should make them 10 times more sensitive and, they say, virtually ensure a detection.

FREAK Attack Threatens SSL Clients 43

Posted by Soulskill
from the another-day-another-vuln dept.
msm1267 writes: For the nth time in the last couple of years, security experts are warning about a new Internet-scale vulnerability, this time in some popular SSL clients. The flaw allows an attacker to force clients to downgrade to weakened ciphers and break their supposedly encrypted communications through a man-in-the-middle attack. Researchers recently discovered that some SSL clients, including OpenSSL, will accept weak RSA keys–known as export-grade keys–without asking for those keys. Export-grade refers to 512-bit RSA keys, the key strength that was approved by the United States government for export overseas. This was an artifact from decades ago and it was thought that most servers and clients had long ago abandoned such weak ciphers. The vulnerability affects a variety of clients, most notably Apple's Safari browser.

+ - Ask Slashdot: What smarthpone for the surveillence-aware late adopter? 1

Submitted by Anonymous Coward
An anonymous reader writes "Hello all,

I am a computer programmer and systems administrator, I am very tech literate — that being said I am also a skeptic when it comes to the necessity of a smartphone and the actual usefulness it will impart on MY life. Conversely, I am all too aware of the negative impact the smartphone will have on my life, mainly it compromises my privacy [more than a dumb phone does]. As a result, I've stuck to my dumb phone. But increasingly lately I feel that I can enhance my privacy by upgrading to a smartphone and using encrypted voice and text apps [and making config changes on the device as necessary].

Another crucial reason for my delayed adoption: I hate touch screens; I don't believe touch screens are "revolutionary"; I don't want to "learn" how to use touch screens. (I'm a backend developer. The fancier and shinier the UI, the less impressed I am.)

The ONLY interest I have in smartphones at this time is the encrypted voice and text apps. I do not need games, or facebook/twitter or email or even an internet browser — I don't like to do those things except on a traditional computer and I don't plan to change my day-to-day lifestyle any time soon except for adopting encrypted voice calls and text messages on a routine basis.

I know back in the early days of smartphones some handsets had physical keyboards. Are these types of devices still actively manufactured or do I need to buy a very old model? I would rather buy a recent model if possible.

Does anyone know of a Android phone with a physical keyboard compatible with recent popular crypto apps? Am I asking for too much?"

A Versatile and Rugged MIDI Mini-Keyboard (Video) 44

Posted by Roblimo
from the Willy-and-the-poor-boys-playing-that-MIDI-can't-be-beat dept.
The K-Board won a "Best in Show" award at CES 2015. Plus, as Timothy said, "I always like pour and stomp demos." And it's totally cross-platform. If your computer, tablet or smartphone has a USB port and (almost) any kind of music software, it works. In theory, you could hook a K-Board to your Android or iOS device and use it to accompany yourself while you sing for spare change on a downtown corner. Or noodle around to get a handle on a theme you'll use in your next major symphony. Or...?

+ - Rosetta snaps a picture of its own shadow on the comet below->

Submitted by mpicpp
mpicpp (3454017) writes "The ESA released an image Tuesday of the comet-orbiting Rosetta leaving a fleeting mark on the comet: its shadow. The space agency describes it as being "encircled in a wreath of light." It was a rare confluence of circumstances that enabled the image to exist as the sun, spacecraft and comet all came into alignment.

The shadow is diffuse, rather than sharp. The ESA explains this by noting, "If you were standing on the surface with Rosetta high above you, there would be no place in the shadow where the entire Sun would be blocked from view, which explains why there is no fully dark core to the shadow."

The image was taken during a close flyby of the comet on February 14, but the ESA just now brought it to the public's attention. Rosetta — which was launched back in 2004 and sent on a mission to approach and study Comet 67P — was at a distance of about 3.7 miles from the comet's surface at the time.

What's so intriguing about the shadow image is that it's something familiar happening in an alien place, 317 million miles away. We're all used to seeing our shadows here on Earth. Rosetta casting a shadow on a comet puts its epic space adventure into a more human perspective."
