OpenSSH Will Feature Key Discovery and Rotation For Easier Switching To Ed25519
2:10 AM - ConstantineM writes: OpenSSH developer Damien Miller has posted about a new feature he implemented and committed for the next upcoming 6.8 release of OpenSSH — hostkeys@openssh.com — an OpenSSH extension to the SSH protocol for sshd to automatically send all of its public keys to the client, and for the client to automatically replace all keys of such server within ~/.ssh/known_hosts with the fresh copies as supplied (provided the server is trusted in the first place, of course). The protocol extension is simple enough, and is aimed to make it easier to switch over from DSA to the OpenSSL-free Ed25519 public keys. It is also designed in such a way as to support the concept of spare host keys being stored offline, which could then seamlessly replace main active keys should they ever become compromised.

8:01 PM - New submitter cbiltcliffe writes: About a month ago, we discussed news that the Pirate Bay domain name was back online. This story mentioned a timer, which supposedly showed the time since the police raid. I didn't notice at the time, but a more recent check showed this counter was counting down, not up, with a time set to reach zero at the end of January. Sometime around a week ago, the waving pirate flag video changed to a graphic of an orange phoenix, and a disabled search box showed up. I've been watching the site since, and now, about 12 hours before the timer was to reach zero, the site is back up, complete with searches.









 

6:59 PM - MarkWhittington writes: Officially, NASA has been charged with sending astronauts to Mars sometime in the 2030s. Toward that end, according to a story in Universe Today, space agency engineers at the Marshall Space Flight Center are looking at an old concept for interplanetary travel, nuclear thermal engines. "...according to the report (cached), an NTP rocket could generate 200 kWt of power using a single kilogram of uranium for a period of 13 years – which works out of to a fuel efficiency rating of about 45 grams per 1000 MW-hr. In addition, a nuclear-powered engine could also provide superior thrust relative to the amount of propellant used." However, some doubts have been expressed whether NASA will be granted the budget to develop such engines.









 

5:55 PM - Bryce writes: Four years since the last major Inkscape release, now news is out about version 0.91 of this powerful vector drawing and painting tool. The main reason for the multi-year delay is that they've switched from their old custom rendering engine to using Cairo now, improving their support for open source standards. This release also adds symbol libraries and support for Visio stencils, cross platform WMF and EMF import and export, a native Windows 64-bit build, scads of bug fixes, and much more.

4:51 PM - theodp writes: In a NY Times Op Ed, developmental psychologist Susan Pinker goes against the conventional White House wisdom about the importance of Internet connectivity for schoolchildren and instead argues that students can have too much tech. "More technology in the classroom has long been a policy-making panacea," Pinker writes. "But mounting evidence shows that showering students, especially those from struggling families, with networked devices will not shrink the class divide in education. If anything, it will widen it." Tech can help the progress of children, Pinker acknowledges, but proper use is the rub. As a cautionary tale, Pinker cites a study by Duke economists that tracked the academic progress of nearly one million disadvantaged middle-school students against the dates they were given networked computers. The news was not good. "Students who gain access to a home computer between the 5th and 8th grades tend to witness a persistent decline in reading and math scores," the economists wrote, adding that license to surf the Internet was also linked to lower grades in younger children.









 

3:51 PM - MojoKid writes: In all of its iterations, NVIDIA's Maxwell architecture has proven to be a good performing, power-efficient GPU thus far. At the high-end of the product stack is where some of the most interesting products reside, however. When NVIDIA launches a new high-end GPU, cards based on the company's reference design trickle out first, and then board partners follow up with custom solutions packing unique cooling hardware, higher clocks, and sometimes additional features. With the GeForce GTX 970 and GTX 980, NVIDIA's board partners were ready with custom solutions very quickly. These three custom GeForce cards, from enthusiast favorites EVGA, MSI, and Zotac represent optimization at the high-end of Maxwell. Two of the cards are GTX 980s: the MSI GTX 980 Gaming 4G and the Zotac GeForce GTX 980 AMP! Omgea, the third is a GTX 970 from EVGA, their GeForce GTX 970 FTW with ACX 2.0. Besides their crazy long names, all of these cards are custom solutions, that ship overclocked from the manufacturer. In testing, NVIDIA's GeForce GTX 980 was the fastest, single-GPU available. The custom, factory overclocked MSI and Zotac cards cemented that fact. Overall, thanks to a higher default GPU-clock, the MSI GTX 980 Gaming 4G was the best performing card. EVGA's GeForce GTX 970 FTW was also relatively strong, despite its alleged memory bug. Although, as expected, it couldn't quite catch the higher-end GeForce GTX 980s, but occasionally outpaced the AMD's top-end Radeon R9 290X.









 

2:48 PM - jones_supa writes: In its latest move, Dell will be bringing Ubuntu 14.04 LTS to its top-of-the-line Precision M3800 workstation laptop and the latest model of the Dell XPS 13. Both systems will be running Ubuntu 14.04.1. According to Barton George, Dell's Director of Developer Programs, programmers had been asking for a better, officially-supported Ubuntu developer laptop. This came about from a combination of the efforts of Dell software engineer Jared Dominguez and enthusiastic feedback. Specs of M3800: 15.6" LCD @ 3840x2160, Intel i7 quad core CPU, NVIDIA Quadro GPU, up to 16 GB RAM. The bad news is, as Dominguez explained on his blog, this version of the M3800 doesn't support its built-in Thunderbolt 2 port out of the box. However, thanks to the hardware-enablement stack in Ubuntu, starting with upcoming Ubuntu 14.04.2, you will be able to upgrade your kernel to add some Thunderbolt support.

Elliott notes although reasons and consequences for this behavior are unknown, "one thing is clear: At least one person, and maybe more than one person, really doesn't like Comcast's customers. Enough to put it in writing. Repeatedly." Comcast has apologized and is looking at ways to prevent it from happening in the future.









 

12:38 PM - An anonymous reader sends word that the UK Army is establishing a dedicated unit for fighting wars in the information age. The 77th Brigade will specialize in non-lethal, psychological operations that involve the internet and social media. The army says it's learned through its operations in Afghanistan that there are fights to be won not just on the battlefield, but online as well. "In some senses it's defensive - trying to present the case from this side against opponents who hold many of the cards. We've seen with Islamic State, its incredible capability on the net, Facebook, Instagram and all the rest." The new unit will "try to influence local populations and change behavior through what the Army calls traditional and unconventional means." The army also stressed that they're looking for ways that citizens with the right skills could work alongside the 77th Brigade.

Younger people (under 30) tend to view the NSA favorably, compared to those 65 and older. 61% of people aged 18-29 viewed the NSA favorably, while 30% viewed the NSA unfavorably and 9% had no opinion. 55% of people aged 30-49 viewed the NSA favorably. At the 65+ age bracket, only 40% of people viewed the NSA favorably.









 

10:30 AM - hypnosec writes: The European Space Agency has made a joint analysis of data gathered by the ground-based BICEP2 and Keck Array experiments and its own Planck satellite to try to verify previous reports of BICEP2's primordial gravitational wave detection. However, the ESA was unable to find evidence of primordial gravitational waves, and they think the earlier report was simply based on an outdated model that didn't take interstellar dust into account. "The Milky Way is pervaded by a mixture of gas and dust shining at similar frequencies to those of the CMB, and this foreground emission affects the observation of the most ancient cosmic light. Very careful analysis is needed to separate the foreground emission from the cosmic background. Critically, interstellar dust also emits polarized light, thus affecting the CMB polarization as well. ... The BICEP2 team had chosen a field where they believed dust emission would be low, and thus interpreted the signal as likely to be cosmological. However, as soon as Planck’s maps of the polarized emission from Galactic dust were released (PDF), it was clear that this foreground contribution could be much higher than previously expected."









 

9:26 AM - theodp writes: Yes, folks, there are blind programmers. There's Ed Summers, for one, who lost his vision at age 30 and now ghostblogs for Willie the Seeing Eye Dog. And if you've ever wondered how the blind can code, Florian Beijers, who has been blind since birth, explains that all he needs is a normal Dell Inspiron 15r SE notebook and his trusty open source NVDA screen reader software, and he's good-to-go. "This is really all the adaptation a blind computer user needs," Beijers adds, but he does ask one small favor: "If you're writing the next big application, with a stunning UI and a great workflow, I humbly ask you to consider accessibility as part of the equation. In this day and age, there's really no reason not to use the UI toolkits available."









 

8:23 AM - HughPickens.com writes James B. Stewart writes in the NYT that in 1998 Bill Gates said in an interview that he "couldn't imagine a situation in which Apple would ever be bigger and more profitable than Microsoft" but less than two decades later, Apple, with a market capitalization more than double Microsoft's, has won. The most successful companies need a vision, and both Apple and Microsoft have one. But according to Stewart, Apple's vision was more radical and, as it turns out, more farsighted. Where Microsoft foresaw a computer on every person's desk, Apple went a big step further: Its vision was a computer in every pocket. "Apple has been very visionary in creating and expanding significant new consumer electronics categories," says Toni Sacconaghi. "Unique, disruptive innovation is really hard to do. Doing it multiple times, as Apple has, is extremely difficult." According to Jobs' biographer Walter Isaacson, Microsoft seemed to have the better business for a long time. "But in the end, it didn't create products of ethereal beauty. Steve believed you had to control every brush stroke from beginning to end. Not because he was a control freak, but because he had a passion for perfection." Can Apple continue to live by Jobs's disruptive creed now that the company is as successful as Microsoft once was? According to Robert Cihra it was one thing for Apple to cannibalize its iPod or Mac businesses, but quite another to risk its iPhone juggernaut. "The question investors have is, what's the next iPhone? There's no obvious answer. It's almost impossible to think of anything that will create a $140 billion business out of nothing."









 

5:40 AM - Mark.JUK writes The national telecoms operator for the United Kingdom, BT, has today announced that it will begin a country-wide deployment of the next generation hybrid-fibre G.fast (ITU G.9701) broadband technology from 2016/17, with most homes being told to expect speeds of up to 500Mbps (Megabits per second) and a premium service offering 1000Mbps will also be available. At present BT already covers most of the UK with hybrid Fibre-to-the-Cabinet (FTTC) technology, which delivers download speeds of up to 80Mbps by running a fibre optic cable to a local street cabinet and then using VDSL2 over the remaining copper line from the cabinet to homes. G.fast follows a similar principal, but it brings the fibre optic cable even closer to homes (often by installing smaller remote nodes on telegraph poles) and uses more radio spectrum (17-106MHz) over a shorter remaining run of copper cable (ideally less than 250 metres). The reliance upon copper cable means that the real-world speeds for some, such as those living furthest away from the remote nodes, will probably struggle to match up to BT's claims. Nevertheless many telecoms operators see this as being a more cost effective approach to broadband than deploying a pure fibre optic / Fibre-to-the-Home (FTTH) network.









 

2:52 AM - An anonymous reader writes "I've never been able to work up a fear of the robot apocalypse," admits R.U. Sirius, who more than 20 years after Mondo 2000's original guide to geek culture has again collaborated on a new encyclopedia of emerging technologies. As we progress to a world where technology actually becomes invisible, he argues that "everything about how we will define the future is still in play," suggesting that the transhumanist movement is "a good way to take isolated radical tech developments and bundle them together". While his co-author argues transhumanists "like to solve everything," Sirius points out a much bigger concern is a future of technologies dominated by the government or big capital.









 

12:09 AM - "Uber has been the subject of controversy all around the globe," notes new submitter yuetteasvy (3999351), who supplies this story from Reuters about one of the reasons for that controversy: An Indian woman who says she was raped by an Uber driver while she was traveling in his cab in December is suing the San Francisco–based online firm in a U.S. federal court in California, claiming it failed to put in place basic safety procedures while running its car service in India. In her lawsuit, filed on Thursday, the New Delhi woman called the app-based service the "modern day equivalent of electronic hitchhiking." The unidentified plaintiff also calls for Uber to overhaul its safety practices, and seeks unspecified damages in the case, according to Reuters. The news agency quoted Uber as saying that it's "deepest sympathies remain with the victim of this horrific crime." Earlier, the woman was reported to have enlisted the services of Douglas Wigdor, a high-profile U.S. lawyer who represented Nafissatou Diallo, the New York City hotel maid who accused the former International Monetary Fund managing director Dominique Strauss-Kahn of sexual assault. Prosecutors from the Manhattan district attorney's office went on to drop all charges against Strauss-Kahn, while a civil suit was settled out of court.









 

9:02 PM - StartsWithABang (3485481) writes "Ever since quantum mechanics first came along, we've recognized how tenuous our perception of reality is, and how — in many ways — what we perceive is just a very small subset of what's going on at the quantum level in our Universe. Then, along came cosmic inflation, teaching us that our observable Universe is just a tiny, tiny fraction of the matter-and-radiation filled space out there, with possibilities including Universes with different fundamental laws and constants, differing quantum outcomes existing in disconnected regions of space, and even the fantastic one of parallel Universes and alternate versions of you and me. But is that last one really admissible? The best modern evidence teaches us that even with all the Universes that inflation creates, it's still a finite number, and an insufficiently large number to contain all the possibilities that a 13.8 billion year old Universe with 10^90 particles admits."









 

6:52 PM - Dave Knott (2917251) writes George R.R. Martin's "The WInds Of Winter", the fifth book of his bestselling fantasy saga "A Song Of Ice And Fire" (known to television fans as "Game Of Thrones") will not be published in 2015. Jane Johnson at HarperCollins has confirmed that it is not in this year's schedule. "I have no information on likely delivery," she said. "These are increasingly complex books and require immense amounts of concentration to write. Fans really ought to appreciate that the length of these monsters is equivalent to two or three novels by other writers."Instead, readers will have to comfort themselves with a collection, illustrated by Gary Gianni, of three previously anthologised novellas set in the world of Westeros. "A Knight of the Seven Kingdoms" takes place nearly a century before the bloody events of the A Song of Ice and Fire series. Out in October, it is a compilation of the first three official prequel novellas to the series, The Hedge Knight, The Sworn Sword and The Mystery Knight, never before collected.









 

6:05 PM - An anonymous reader writes: Data science — or "big data" if you prefer — has evolved into a full-fledged buzzword, thanks to marketing departments around the world. John Foreman writes that part of the marketing blitz has been focused on how fast big data analysis can be. Most companies offering some kind of analytic service try to sell you on how it'll make it easy for you to quickly find and fix the problems with your business. But he points out that good, robust models need a stable set of inputs, and businesses often change far too quickly for any kind of stable prediction. He takes IBM's analytic services as an example, quoting Kevin Hillstrom: "If IBM Watson can find hidden correlations that help your business, then why can't IBM Watson stem a 3 year sales drop at IBM?" Foreman offers some simple advice: "Simple analyses don't require huge models that get blown away when the business changes. ... If your business is currently too chaotic to support a complex model, don't build one."
