Ubuntu 15.04 Released, First Version To Feature systemd

Fri, 04/24/2015 - 09:13
jones_supa writes: The final release of Ubuntu 15.04 is now available. A modest set of improvements are rolling out with this spring's Ubuntu. While this means the OS can't rival the heavy changelogs of releases past, the adage "don't fix what isn't broken" is clearly one 15.04 plays to. The headline change is systemd being featured first time in a stable Ubuntu release, which replaces the inhouse UpStart init system. The Unity desktop version 7.3 receives a handful of small refinements, most of which aim to either fix bugs or correct earlier missteps (for example, application menus can now be set to be always visible). The Linux version is 3.19.3 further patched by Canonical. As usual, the distro comes with fresh versions of various familiar applications.

Comcast Officially Gives Up On TWC Merger

Fri, 04/24/2015 - 08:31
An anonymous reader writes: Confirming speculation from yesterday, Comcast announced this morning that its attempt to merge with Time Warner Cable has been terminated. The announcement was very brief, but indicated that regulatory pressure was the reason they killed the deal. CEO Brian Roberts said, "Today, we move on. Of course, we would have liked to bring our great products to new cities, but we structured this deal so that if the government didn't agree, we could walk away." The Washington Post adds, "The move by regulators to throw up roadblocks shows that the government has grown concerned about massive media conglomerates bigfooting rivals that are finding success by streaming content over the Internet, analysts said. And after years of approving a wave of mergers in the industry — including that of Comcast and NBC Universal in 2011 — federal officials are taking a new tone, they said."

Hubble Turns 25

Fri, 04/24/2015 - 07:49
Taco Cowboy points out that the Hubble Space Telescope turns 25 today. Hubble was launched on April 24, 1990, aboard the Space Shuttle Discovery from Kennedy Space Center, Florida. Currently, it is flying about 340 miles over the Earth and circling us every 97 minutes. While the telescope itself is not really much to look at, that silver bucket is pure gold for astronomers. Scientists have used that vantage point to make ground-breaking observations about planets, stars, galaxies and to reveal parts of our universe we didn't know existed. The telescope has made more than a million observations and astronomers have used Hubble data in more than 12,700 scientific papers, "making it one of the most productive scientific instruments ever built," according to NASA. ... NASA aims to keep Hubble operating through at least 2020 so that it can overlap with its successor. The James Webb Space Telescope is due to launch in October 2018 and begin observations in mid-2019. NASA celebrated by releasing a new, epic image from Hubble titled "Celestial Fireworks." It is accompanied by an impressive flythrough video. Some nice galleries of Hubble images have been put together at the NY Times and Slate, but a bigger collection is available directly from the official Hubble website.

Cosmic Rays Could Reveal Secrets of Lightning On Earth

Fri, 04/24/2015 - 07:06
sciencehabit writes: Despite Benjamin Franklin's best efforts with a kite and a key, the phenomenon of lightning remains a scientific enigma. Now, researchers have developed a new tool that could help them solve some of lightning's mysteries. By using cosmic rays, space-traveling particles that constantly rain down on our atmosphere, scientists report they can peek inside thunderstorms and measure their electric fields, helping them pinpoint the conditions that cause storms' electrical outbursts. The advance could help researchers predict more precisely when and where lightning is most likely to strike and get people out of harm's way in time.

MIT Developing AI To Better Diagnose Cancer

Fri, 04/24/2015 - 04:30
stowie writes: Working with Massachusetts General Hospital, MIT has developed a computational model that aims to automatically suggest cancer diagnoses by learning from thousands of data points from past pathology reports. The core idea is a technique called Subgraph Augmented Non-negative Tensor Factorization (SANTF). In SANTF, data from 800-plus medical cases are organized as a 3D table where the dimensions correspond to the set of patients, the set of frequent subgraphs, and the collection of words appearing in and near each data element mentioned in the reports. This scheme clusters each of these dimensions simultaneously, using the relationships in each dimension to constrain those in the others. Researchers can then link test results to lymphoma subtypes.

NVIDIA Quadro M6000 12GB Maxwell Workstation Graphics Tested Showing Solid Gains

Fri, 04/24/2015 - 02:05
MojoKid writes: NVIDIA's Maxwell GPU architecture has has been well-received in the gaming world, thanks to cards like the GeForce GTX Titan X and the GeForce GTX 980. NVIDIA recently took time to bring that same Maxwell goodness over the workstation market as well and the result is the new Quadro M6000, NVIDIA's new highest-end workstation platform. Like the Titan X, the M6000 is based on the full-fat version of the Maxwell GPU, the G200. Also, like the GeForce GTX Titan X, the Quadro M6000 has 12GB of GDDR5, 3072 GPU cores, 192 texture units (TMUs), and 96 render outputs (ROPs). NVIDIA has said that the M6000 will beat out their previous gen Quadro K6000 in a significant way in pro workstation applications as well as GPGPU or rendering and encoding applications that can be GPU-accelerated. One thing that's changed with the launch of the M6000 is that AMD no longer trades shots with NVIDIA for the top pro graphics performance spot. Last time around, there were some benchmarks that still favored team red. Now, the NVIDIA Quadro M6000 puts up pretty much a clean sweep.

Good: Companies Care About Data Privacy Bad: No Idea How To Protect It

Thu, 04/23/2015 - 23:36
Esther Schindler writes: Research performed by Dimensional Research demonstrated something most of us know: Just about every business cares about data privacy, and intends to do something to protect sensitive information. But when you cross-tabulate the results to look more closely at what organizations are actually doing to ensure that private data stays private, the results are sadly predictable: While smaller companies care about data privacy just as much as big ones do, they're ill-equipped to respond. What's different is not the perceived urgency of data privacy and other privacy/security matters. It's what companies are prepared (and funded) to do about it. For instance: "When it comes to training employees on data privacy, 82% of the largest organizations do tell the people who work for them the right way to handle personally identifiable data and other sensitive information. Similarly, 71% of the businesses with 1,000-5,000 employees offer such training. However, even though smaller companies are equally concerned about the subject, that concern does not trickle down to the employees quite so effectively. Half of the midsize businesses offer no such training; just 39% of organizations with under 100 employees regularly train employees on data privacy."

Music Industry Argues Works Entering Public Domain Are Not In Public Interest

Thu, 04/23/2015 - 20:58
An anonymous reader writes: With news that Canada intends to extend the term of copyright for sound recordings and performers, the recording industry is now pushing the change by arguing that works entering the public domain is not in the public interest. It is hard to see how anyone can credibly claim that works are "lost" to the public domain and that the public interest in not served by increased public access, but if anyone would make the claim, it would be the recording industry.

Groupon Refuses To Pay Security Expert Who Found Serious XSS Site Bugs

Thu, 04/23/2015 - 18:57
Mark Wilson writes: Bounty programs benefit everyone. Companies like Microsoft get help from security experts, customers gain improved security, and those who discover and report vulnerabilities reap the rewards financially. Or at least that's how things are supposed to work. Having reported a series of security problems to discount and deal site Groupon, security researcher Brute Logic from XSSposed.org was expecting a pay-out — but the site refuses to give up the cash. In all, Brute Logic reported more than 30 security issues with Groupon's site, but the company cites its Responsible Disclosure policy as the reason for not handing over the cash.

Median Age At Google Is 29, Says Age Discrimination Lawsuit

Thu, 04/23/2015 - 18:15
dcblogs writes: The typical employee at Google is relatively young, according to a lawsuit brought by an older programmer who is alleging age discrimination. Between 2007 and 2013, Google's workforce grew from 9,500 to more than 28,000 employees, "yet as of 2013, its employees' median age was 29 years old," the lawsuit claims. That's in contrast to the median age of nearly 43 for all U.S. workers who are computer programmers, according to the lawsuit.

Gen. Petraeus To Be Sentenced To Two Years Probation and Fine

Thu, 04/23/2015 - 17:51
An anonymous reader writes: Petraeus, a now-retired U.S. Army General, has already agreed to plead guilty to a criminal misdemeanor charge of unauthorized removal and retention of classified material. As part of the agreement with prosecutors filed in March, the government will not seek any prison time. Instead, Petraeus will agree to pay a $40,000 fine and receive two years of probation, according to court documents. The recommendations are not binding on the federal judge who will preside at the hearing Thursday afternoon in Charlotte.

Researcher Discloses Methods For Bypassing All OS X Security Protections

Thu, 04/23/2015 - 17:30
Trailrunner7 writes: For years, Apple has enjoyed a pretty good reputation among users for the security of its products. That halo has been enhanced by the addition of new security features such as Gatekeeper and XProtect to OS X recently, but one researcher said that all of those protections are simple to bypass and gaining persistence on a Mac as an attacker isn't much of a challenge at all. Gatekeeper is one of the key technologies that Apple uses to prevent malware from running on OS X machines. It gives users the ability to restrict which applications can run on their machines by choosing to only allow apps from the Mac App Store. With that setting in play, only signed, legitimate apps should be able to run on the machine. But Patrick Wardle, director of research at Synack, said that getting around that restriction is trivial. "Gatekeeper doesn't verify an extra content in the apps. So if I can find an Apple-approved app and get it to load external content, when the user runs it, it will bypass Gatekeeper," Wardle said in a talk at the RSA Conference here Thursday. "It only verifies the app bundle. If Macs were totally secure, I wouldn't be here talking," Wardle said. "It's trivial for any attacker to bypass the security tools on Macs."

Yellowstone Supervolcano Even Bigger Than We Realized

Thu, 04/23/2015 - 16:47
The Washington Post reports that the "supervolcano" beneath Yellowstone National Park (which, thankfully, did not kill us all in 2004, or in 2008 ) may be more dangerous when it does erupt than anyone realized until recently. Scientists have today published a paper documenting their discovery of an even larger, deeper pool of magma below the already huge reservoir near the surface. From the article: On Thursday, a team from the University of Utah published a study, in the journal Science, that for the first time offers a complete diagram of the plumbing of the Yellowstone volcanic system. The new report fills in a missing link of the system. It describes a large reservoir of hot rock, mostly solid but with some melted rock in the mix, that lies beneath a shallow, already-documented magma chamber. The newly discovered reservoir is 4.5 times larger than the chamber above it. There's enough magma there to fill the Grand Canyon. The reservoir is on top of a long plume of magma that emerges from deep within the Earth's mantle. ... “This is like a giant conduit. It starts down at 1,000 kilometers. It's a pipe that starts down in the Earth," said Robert Smith, emeritus professor of geophysics at the University of Utah and a co-author of the new paper. ... The next major, calderic eruption could be within the boundaries of the park, northeast of the old caldera. “If you have this crustal magma system that is beneath the pre-Cambrian rocks, eventually if you get enough fluid in that system, enough magma, you can create another caldera, another set of giant explosions," Smith said. "There’s no reason to think it couldn’t continue that same process and repeat that process to the northeast.”

We'll Be the Last PC Company Standing, Acer CEO Says

Thu, 04/23/2015 - 15:48
Velcroman1 writes: At a sky-high press conference atop the new World Trade Center in lower Manhattan, Acer unveiled a sky-high lineup of goods – and placed a flag in the sand for the sagging PC industry. "There are only four or five players in the PC industry, and all of us are survivors," Jason Chen, CEO of Acer Corp, told an international group of reporters. "We will be the last man standing for the PC industry." To that end, the company showed off a slew of new laptops and 2-in-1s, the new Liquid X2 smartphone, and introduces a new line of gaming PCs, called Predator. I suspect Apple will outlive Acer; who do you think will fall next (or rise next)?

Virtual Telescope Readied To Image Black Hole's 'Ring of Fire'

Thu, 04/23/2015 - 14:05
astroengine writes: With the addition of a telescope at the southern-most point of Earth, the Event Horizon Telescope (EHT) now spans the diameter of our planet and, when the vast project goes online, astronomers will get their first glimpse of the bright ring surrounding a supermassive black hole. Using a method known as Very Long Baseline Interferometry, or VLBI, astronomers can combine the observing power of many telescopes situated at distant locations around the planet. The distance between those observatories, known as the "baseline," then mimics a virtual telescope of that diameter. Now, in an attempt to make direct observations of the supermassive black hole in the center of our galaxy, located at a powerful radio emission source called Sagittarius A*, the South Pole Telescope (SPT) at the National Science Foundation's Amundsen-Scott South Pole Station has been linked to the EHT and the stage is set for a historic new era of exploring the most extreme objects in the known universe. "Now that we've done VLBI with the SPT, the Event Horizon Telescope really does span the whole Earth, from the Submillimeter Telescope on Mount Graham in Arizona, to California, Hawaii, Chile, Mexico, Spain and the South Pole," said Dan Marrone of the University of Arizona. "The baselines to SPT give us two to three times more resolution than our past arrays, which is absolutely crucial to the goals of the EHT. To verify the existence of an event horizon, the 'edge' of a black hole, and more generally to test Einstein's theory of general relativity, we need a very detailed picture of a black hole. With the full EHT, we should be able to do this."

Drone Killed Hostages From U.S. and Italy, Drawing Obama Apology

Thu, 04/23/2015 - 12:43
HughPickens.com writes: The NYT reports that President Obama has offered an emotional apology for the accidental killing of two hostages held by Al Qaeda, one of them American, in a United States government counterterrorism operation in January, saying he takes "full responsibility" for their deaths. "As president and as commander in chief, I take full responsibility for all our counterterrorism operations," including the one that inadvertently took the lives of the two captives, a grim-faced Obama said in a statement to reporters in the White House briefing room. The White House earlier released an extraordinary statement revealing that intelligence officials had confirmed that Warren Weinstein, an American held by Al Qaeda since 2011, and Giovanni Lo Porto, an Italian held since 2012, died during the operation. Gunmen abducted Warren Weinstein in 2011 from his home in Lahore, Pakistan. They posed as neighbors, offered food and then pistol-whipped the American aid worker and tied up his guards, according to his daughter Alisa Weinstein. The White House did not explain why it has taken three months to disclose the episode. Obama said that the operation was conducted after hundreds of hours of surveillance had convinced American officials that they were targeting an Al Qaeda compound where no civilians were present, and that "capturing these terrorists was not possible." The White House said the operation that killed the two hostages "was lawful and conducted consistent with our counterterrorism policies" but nonetheless the government is conducting a "thorough independent review" to determine what happened and how such casualties could be avoided in the future.

Africa E-Waste Dump Continues Hyperbole War

Thu, 04/23/2015 - 11:57
retroworks writes: Two stories appear today which feature close up photos of young African men surrounded by scrap metal in the city of Accra. The headlines state that this is where our computers go to die (Wired). The Daily Mail puts it in even starker terms, alleging "millions of tons" are dumped in Agbogbloshie. The stories appear the same day as a press release by investigators who returned this week from 3 weeks at the site. The release claims that Agbogbloshie's depiction as the worlds "largest ewaste dump site" to be a hoax. It is a scrap automobile yard which accounts for nothing more than local scrap from Accra. Three Dagbani language speaking electronics technicians, three reporters, Ghana customs officials and yours truly visited the site, interviewed workers about the origins of the material, and assessed volumes. About 27 young men burn wire, mostly from automobile scrap harnesses. The electronics — 20 to 50 items per day — are collected from Accra businesses and households. The majority of Accra (population 5M) have had televisions since the 1990s, according to World Bank metadata (over 80% by 2003). The investigation did confirm that most of the scrap was originally imported used, and that work conditions were poor. However, the equipment being recycled had been repaired and maintained, typically for a decade (longer than the original OECD owner). It is a fact that used goods will, one day, eventually become e-waste. Does that support a ban on the trade in used goods to Africa? Or, as the World Bank reports, is the affordable used product essential to establish a critical mass of users so that investment in highways, phone towers, and internet cable can find necessary consumers?
