  • The Joys and Hype of Hadoop

    theodp writes "Investors have poured over $2 billion into businesses built on Hadoop," writes the WSJ's Elizabeth Dwoskin, "including Hortonworks Inc., which went public last week, its rivals Cloudera Inc. and MapR Technologies, and a growing list of tiny startups. Yet companies that have tried to use Hadoop have met with frustration." Dwoskin adds that Hadoop vendors are responding with improvements and additions, but for now, "It can take a lot of work to combine data stored in legacy repositories with the data that's stored in Hadoop. And while Hadoop can be much faster than traditional databases for some purposes, it often isn't fast enough to respond to queries immediately or to work on incoming information in real time. Satisfying requirements for data security and governance also poses a challenge."

  • NASA Study Proposes Airships, Cloud Cities For Venus Exploration

    An anonymous reader writes: IEEE Spectrum reports on a study out of NASA exploring the idea that manned missions to Venus are possible if astronauts deploy and live in airships once they arrive. Since the atmospheric pressure at the surface is 92 times that of Earth, and the surface temperate is over 450 degrees C, the probes we've sent to Venus haven't lasted long. The Venera 8 probe sent back data for only 50 minutes after landing. Soviet missions in 1985 were able to get much more data — 46 hours worth — by suspending their probes from balloons. The new study refines that concept: "At 50 kilometers above its surface, Venus offers one atmosphere of pressure and only slightly lower gravity than Earth. Mars, in comparison, has a "sea level" atmospheric pressure of less than a hundredth of Earth's, and gravity just over a third Earth normal. The temperature at 50 km on Venus is around 75 C, which is a mere 17 degrees hotter than the highest temperature recorded on Earth.

    The defining feature of these missions is the vehicle that will be doing the atmospheric exploring: a helium-filled, solar-powered airship. The robotic version would be 31 meters long (about half the size of the Goodyear blimp), while the crewed version would be nearly 130 meters long, or twice the size of a Boeing 747. The top of the airship would be covered with more than 1,000 square meters of solar panels, with a gondola slung underneath for instruments and, in the crewed version, a small habitat and the ascent vehicle that the astronauts would use to return to Venus's orbit, and home."

  • In IT, Beware of Fad Versus Functional

    Lemeowski writes: Cloud, big data, and agile were three of the technology terms that were brandished the most by IT leaders in 2014. Yet, there could be a real danger in buying into the hype without understanding the implications of the technologies, writes Pearson CTO Sven Gerjets. In this essay, Gerjets warns that many IT executives drop the ball when it comes to "defining how a new technology approach will add value" to their organization. He says: "Yes, you can dive into an IT fad without thinking about it, but I can promise you'll look back and be horrified someday. The only time you can fully adopt some of these new methods is when you are starting from scratch. Most of us don't have that luxury because we are working with legacy architectures and technical debt so you have to play hand you've been dealt, communicate well, set clear and measurable outcomes, and use these fads to thoughtfully supplement the environment you are working in to benefit the ecosystem."

  • Microsoft To Open Source Cloud Framework Behind Halo 4 Services

    angry tapir writes Microsoft plans to open-source the framework that helps developers of cloud services like those behind Halo 4. Project Orleans is a framework built by the eXtreme Computing Group at Microsoft Research using .NET, designed so developers who aren't distributed systems experts can build cloud services that scale to cope with high demand and still keep high performance. The Orleans framework was used to build several services on Azure, including services that are part of Halo 4. The code will be released under an MIT license on GitHub early next year.

  • Once Again, Baltimore Police Arrest a Person For Recording Them

    MobyDisk writes: A lawsuit was filed yesterday over a case in which a woman was arrested for recording the police from her car while stopped in traffic. Ars Technica writes, "Police erased the 135-second recording from the woman's phone, but it was recovered from her cloud account according to the Circuit Court for Baltimore City lawsuit, which seeks $7 million."

    Baltimore police lost a similar case against Anthony Graber in 2010 and another against Christopher Sharp in 2014. The is happening so often in Baltimore that in 2012, the U.S. Department of Justice sent a letter to the police reminding them that they cannot stop recordings, and most certainly cannot delete them.

    Local awareness of this issue is high since the the Mayor and the City Council support requiring police body cameras. The city council just passed a bill requiring them, but the mayor is delaying implementation until a task force determines how best to go about it. The country is also focused on police behavior in light of the recent cases in Ferguson and New York, the latter of which involved a citizen recording.

    So the mayor, city council, police department policies, courts, and federal government are all telling police officers to stop doing this. Yet it continues to happen, and in a rather violent matter. What can people do to curb this problem?

  • Liquid Cooling On the Rise As Data Centers Crunch Bigger Data

    1sockchuck writes The use of liquid cooling will accelerate in the next five years, according to experts in high performance computing, who cite the data-crunching requirements of scientific research, cloud computing, bitcoin and "big data" analytics. "In the HPC world, everything will move to liquid cooling," said Paul Arts, technical director of Eurotech. But there's still plenty of resistance from data center operators wary of bringing liquid near servers, and cost is also an issue. Liquid cooling can offer significant savings over the life of a project, but the up-front installation cost can be higher than those for air-cooled systems. Immersion cooling has gotten a surprise boost from the rise of bitcoin, including a large bitcoin mine inside a Hong Kong high-rise.

  • Ubuntu Gets Container-Friendly "Snappy" Core

    judgecorp writes: Canonical just announced Ubuntu Core, which uses containers instead of packages. It's the biggest Ubuntu shakeup for 20 years, says Canonical's Mark Shuttleworth, and is based on a tiny core, which will run Docker and other container technology better, quicker and with greater security than other Linux distros. Delivered as alpha code today, it's going to become a supported product, designed to compete with both CoreOS and Red Hat Atomic, the two leading container-friendly Linux approaches. Shuttleworth says it came about because Canonical found it had solved the "cloud" problems (delivering and updating apps and keeping security) by accident — in its work on a mobile version of Ubuntu.

  • Microsoft To US Gov't: the World's Servers Are Not Yours For the Taking

    Microsoft is currently fighting a legal battle with the U.S. government, who wants to search the company's servers in Ireland using a U.S. search warrant. An anonymous reader points out a new court filing from Microsoft that argues the U.S. itself would never stand for such reasoning from other governments. Microsoft General Counsel Brad Smith writes, If the Government prevails, how can it complain if foreign agents require tech companies to download emails stored in the U.S.? This is a question the Department of Justice hasn’t yet addressed, much less answered. Yet the Golden Rule applies to international relations as well as to other human interaction. In one important sense, the issues at stake are even bigger than this. The Government puts at risk the fundamental privacy rights Americans have valued since the founding of the postal service. This is because it argues that, unlike your letters in the mail, emails you store in the cloud cease to belong exclusively to you. Instead, according to the Government, your emails become the business records of a cloud provider. Because business records have a lower level of legal protection, the Government claims it can use a different and broader legal authority to reach emails stored anywhere in the world.

  • Fedora 21 Released

    linuxscreenshot writes: The Fedora Project has announced the release of Fedora 21. "As part of the Fedora.next initiative, Fedora 21 comes in three flavors: Cloud, Server, and Workstation. Cloud is now a top-level deliverable for Fedora 21, and includes images for use in private cloud environments like OpenStack, as well as AMIs for use on Amazon, and a new "Atomic" image streamlined for running Docker containers. The Fedora Server flavor is a common base platform that is meant to run featured application stacks, which are produced, tested, and distributed by the Server Working Group. The Fedora Workstation is a new take on desktop development from the Fedora community. Our goal is to pick the best components, and integrate and polish them. This work results in a more polished and targeted system than you've previously seen from the Fedora desktop." Here are screenshots for Fedora 21: GNOME, KDE, Xfce, LXDE, and MATE.

  • Node.js Forked By Top Contributors

    New submitter jonhorvath writes: Several of the top contributors to Node.js, a popular open source run-time environment, have decided to fork the project, creating io.js as an alternative. The developers were unhappy with how cloud computing company Joyent was directing work on Node.js. Mikeal Rogers said, "We don't want to have just one person who's appointed by a company making decisions. We want contributors to have more control, to seek consensus." Here's the new repository, and a README file to go with it. A developer at Uber tweeted that they've already migrated to io.js on their production systems. It'll be interesting to see how many other sites follow.

  • Google Confirms That It's Designing Kid-Friendly Versions of Its Services

    An anonymous reader writes USA Today reports that rumors about Google working on specific services catering to young kids are true. From the article: "With Google processing 40,000 search queries a second — or 1.2 trillion a year — it's a safe bet that many of those doing the Googling are kids. Little surprise then that beginning next year the tech giant plans to create specific versions of its most popular products for those 12 and younger. The most likely candidates are those that are already popular with a broad age group, such as search, YouTube and Chrome. 'The big motivator inside the company is everyone is having kids, so there's a push to change our products to be fun and safe for children,' Pavni Diwanji, the vice president of engineering charged with leading the new initiative, told USA TODAY. 'We expect this to be controversial, but the simple truth is kids already have the technology in schools and at home,' says the mother of two daughters, ages 8 and 13. 'So the better approach is to simply see to it that the tech is used in a better way.'"

  • Google Hopes To One Day Replace Gmail With Inbox

    An anonymous reader writes Three Inbox by Gmail engineers today answered questions as part of a Reddit AMA session. Most of the answers were tidbits we've heard of before, but one stood out to us: Google plans to eventually replace Gmail with Inbox. In response to the question "Do you think Inbox will replace Gmail on the long road?," lead designer Jason Cornwell gave the following answer: "In the short term, no. In the very long term, we hope so. Inbox is something new — that's why we're launching it as a separate product. We care deeply about Gmail and Gmail users, but in the long run as we add more features to Inbox and respond to user feedback we hope that everyone will want to use Inbox instead of Gmail. Ultimately, our users will decide." The followup question asks how Google believed one email product possibly target both casual (Gmail) and power (Inbox) users, to which Cornwell replied: "They are not aimed at fundamentally different audiences. Both Gmail and Inbox are designed to scale from low volume to high volume users."

  • How the FCC CIO Plans To Modernize 207 Legacy IT Systems

    Lemeowski writes in with this interview of FCC CIO David Bray. "When David Bray took over as CIO of the FCC last year, he found the agency saddled with 207 legacy systems, which is about one system for every eight employees in the 1,750-person agency. Bray, who is one of the youngest CIOs across the federal government, shares his plan for updating those systems to a cloud-based, common data platform, that's "ideally open source." In this interview, Bray shares the challenges the FCC faces as it upgrades its systems, including keeping up morale and finding a way to fit longtime employees into his modernization strategy."

  • Clarificiation on the IP Address Security in Dropbox Case

    Bennett Haselton writes A judge rules that a county has to turn over the IP addresses that were used to access a county mayor's Dropbox account, stating that there is no valid security-related reason why the IP addresses should be exempt from a public records request. I think the judge's conclusion about IP addresses was right, but the reasoning was flawed; here is a technically more correct argument that would have led to the same answer. Keep Reading to see what Bennett has to say about the case.

  • NSF Commits $16M To Build Cloud-Based and Data-Intensive Supercomputers

    aarondubrow writes: As supercomputing becomes central to the work and progress of researchers in all fields, new kinds of computing resources and more inclusive modes of interaction are required. The National Science Foundation announced $16M in awards to support two new supercomputing acquisitions for the open science community. The systems — "Bridges" at the Pittsburgh Supercomputing Center and "Jetstream," co-located at the Indiana University Pervasive Technology Institute and The University of Texas at Austin's Texas Advanced Computing Center — respond to the needs of the scientific computing community for more high-end, large-scale computing resources while helping to create a more inclusive computing environment for science and engineering. Reader 1sockchuck adds this article about why funding for the development of supercomputers is more important than ever: America's high-performance computing (HPC) community faces funding challenges and growing competition from China and other countries. At last week's SC14 conference, leading researchers focused on outlining the societal benefits of their work, and how it touches the daily lives of Americans. "When we talk at these conferences, we tend to talk to ourselves," said Wilf Pinfold, director of research and advanced technology development at Intel Federal. "We don't do a good job communicating the importance of what we do to a broader community." Why the focus on messaging? Funding for American supercomputing has been driven by the U.S. government, which is in a transition with implications for HPC funding. As ComputerWorld notes, climate change skeptic Ted Cruz is rumored to be in line to chair a Senate committee that oversees NASA and the NSF.

  • Intel Planning Thumb-Sized PCs For Next Year

    angry tapir (1463043) writes Intel is shrinking PCs to thumb-sized "compute sticks" that will be out next year. The stick will plug into the back of a smart TV or monitor "and bring intelligence to that," said Kirk Skaugen, senior vice president and general manager of the PC Client Group at Intel, during the Intel investor conference in Santa Clara, California. They might be a bit late to the party, but since Skaugen mentioned both Chromecast and Amazon's Fire TV Stick, hopefully that means Intel has some more interesting and general-purpose plans.

  • BitTorrent Unveils Sync 2.0

    An anonymous reader writes BitTorrent today outlined the company's plans for its file synchronization tool Sync. Next year, the company will launch Sync 2.0, finally taking the product out of beta, as well as three new paid Sync products. Ever since its debut, Sync has provided a wide variety of solutions to various problems, BitTorrent says, from distributing files across remote servers to sharing vacation photos. BitTorrent thus believes it needs to build three distinct products for each of these separate audiences, including a Pro version for $40 per year.

  • Microsoft Azure Outage Across the Globe

    hawkinspeter writes: The BBC reports that overnight an outage of Microsoft's Azure cloud computing platform took down many third-party sites that rely on it, in addition to disrupting Microsoft's own products. Office 365 and Xbox Live services were affected.

    This happened at a particularly inopportune time, as Microsoft has recently been pushing its Azure services in an effort to catch up with other providers such as Amazon, IBM, and Google. Just a couple of hours previously, Microsoft had screened an Azure advert in the UK during the Scotland v. England soccer match."
    (Most services are back online. As of this writing, Application Insights is still struggling, and Europe is having problems with hosted VMs.)

  • Nvidia Shield Tablet Gets Android Lollipop Update, Half Life 2 EP1 and GRID

    MojoKid writes Nvidia's Shield Tablet is only a few months old, but Nvidia is already updating the device with a freshly minted OS, a refreshed Shield Hub and access to the company's newly upgraded GRID Game Streaming service. A number of new Tegra K1 optimized games are arriving as well, as well as a new game bundle which includes Half Life 2 Episode 1. The SHIELD Tablet Android Lollipop update will feature Android's new "material design" interface and improved app performance, according to Nvidia. The update will also come preloaded with a new version of Nvidia's own Dabbler drawing and painting app (Dabbler 2.0). In addition to a new interface inspired by Lollipop's design language, Dabbler 2.0 will offer full support for layers and it'll allow users to share their sessions over Twitch. Previously, accessing the Nvidia's GRID beta meant streaming games from a GRID server cluster on the west coast, but Nvidia is expanding the service with server clusters located in Virginia, Europe and Asia. For the best possible user experience, streaming games from the cloud must incur minimal latency, and adding more servers in strategic locations not only affords Nvidia greater capacity, but minimizes latency as well. Nvidia says the GRID service will be available in North America this month, Western Europe in December and Asia sometime next year. The company's GRID service gives gamers access to 20 top titles currently, including Batman Arkham City, Borderlands 2 and Psychonauts, among others, and Nvidia is planning to add new games every week.
