Submission + - Futuristic UC Berkeley OS controls discrete 'manycore' resources (networkworld.com)

coondoggie writes: At the Design Automation Conference (DAC) here this week, John Kubiatowicz, professor in the UC Berkeley computer science division, offered a preview of Tessellation, describing it as an operating system for the future where surfaces with sensors, such as walls and tables in rooms, for example, could be utilized via touch or audio command to summon up multimedia and other applications. The UC Berkeley Tessellation website says Tessellation is targeted at existing and future so-called "manycore" based systems that have large numbers of processors, or cores on a single chip. Currently, the operating system runs on Intel multicore hardware as well as the Research Accelerator for Multiple Processors (RAMP) multicore emulation platform.

Submission + - After firestorm, TSA nixes notion to allow pocket knives in passenger carry-ons (networkworld.com)

coondoggie writes: After a major conflagration of criticism from Congress and flight attendants over the Transportation Security Administration's proposed decision in March to let a bunch of previously prohibited items such as small pocket knives on aircraft as carry-ons, the TSA has had a change of heart.

Submission + - NASA teams with Lego to offer coolest, most realistic model competition (networkworld.com)

coondoggie writes: Seems like a natural fit: NASA today said it would team up with Lego to offer a competition to see who can build the coolest models of future airplanes and spacecraft. The "NASA's Missions: Imagine and Build" competition is open now with an entry deadline of July 31. Winners in each category will be selected by a panel of NASA and LEGO officials and announced Sept. 1.

Submission + - IBM touts nickel-sized chip that backs Gb/sec wireless, sharper radar images (networkworld.com)

coondoggie writes: IBM says it has packed an integrated circuit about the size of a nickel with technology that can enable gigabit/sec mobile data-rate and clutter-cutting radar image applications. The integrated circuit takes advantage of millimeter-wave spectrum which spans the 30 GHz to 300 GHz range, 10 to 100 times higher than the frequencies used for mobile phones and Wi-Fi. Frequencies in the range of 90-94GHz are well suited for short and long range, high-resolution radar imaging, IBM said.

Submission + - Malicious power-charger can infect Apple iOS devices (networkworld.com)

coondoggie writes: IoS devices are vulnerable to malware coming from a malicious charger according to researchers from Georgia Tech. The researchers, who will be presenting their proof-of-concept charger known as Mactans at the upcoming Black Hat security conference, say: “despite the plethora of defense mechanisms in iOS, we successfully injected arbitrary software into current-generation Apple devices running the latest operating system (OS) software. All users are affected, as our approach requires neither a jail-broken device nor user interaction.”

Submission + - Get ready for a flood of new Hadoop apps (networkworld.com)

Brandon Butler writes: It's a big week for Hadoop. The latest release of Apache Hadoop code includes a new workload management tool that backers of the project say will make it easier for developers to build applications for the big data platform.

Hadoop systems have thus far relied on MapReduce to process data, but Yarn is a new platform to run applications within Hadoop that is expected to be released in the beta 2.0 version of the open source code this week. Yarn monitors the resources applications need and provisions capacity within the distributed computing system.

Yarn now allows Hadoop systems to run multiple applications at once, instead of bolting on functionality to MapReduce. Developers can also now write apps to Yarn specifications and be assured that they'll work in a Hadoop system. Backers expect that Yarn could open the floodgates for new applications being built to run on Hadoop.

Already some projects, like Apache Tez, have been created to do more advanced data processing compared to what MapReduce specializes in. Tez uses real-time analytics and in-memory processing for higher-speed queries, for example. There are many more applications expected for streaming analytics, such as Twitter Storm while other ETL and real-time processing apps are expected to be developed as well.

Submission + - NASA: Asteroid-based manufacturing not science-fiction (networkworld.com)

coondoggie writes: The idea of building a robotic manufacturing facility in space might have been in the realm of a Star Wars, Star Trek or other science fiction story, but like some of the technologies in those tales, reality may soon imitate art.
Because asteroids are loaded with minerals that are rare on Earth, near-Earth asteroids and the asteroid belt could become the mining centers for remotely operated excavators and processing machinery. In 20 years, an industry barely imagined now could be sending refined materials, rare metals and even free, clean energy to the Earth from asteroids and other bodies," according to NASA scientists in a recently published paper entitled: "Affordable, Rapid Bootstrapping of the Space Industry and Solar System Civilization."

Submission + - US DOJ lays out cybersecurity basics every company should practice (networkworld.com)

coondoggie writes: The mantra is old, grant you, but worth repeating since its obvious from the amount of cybersecurity breaches that not everyone is listening. Speaking at the Georgetown Cybersecurity Law Institute this week, Deputy Attorney General of the United States James Cole said there are a ton of things companies can do to help government and vice-versa, combat cyber threats through better prevention, preparedness, and incidence response.

Submission + - Scientists growing new crystals to make LED lights useful for office, home (networkworld.com)

coondoggie writes: When to comes to offering warm yet visually efficient lighting, LEDs have a long way to go. But scientists with the University of Georgia and Oak Ridge and Argonne national laboratories are looking at new family of crystals they say glow different colors and hold the key for letting white LED light shine in homes and offices as well as natural sunlight.

Submission + - NASA pondering bleak future of exoplanet-hunter (networkworld.com)

coondoggie writes: NASA and a team of other experts will in the next few weeks evaluate options for recovering the crippled space telescope Kepler. NASA's Kepler, which has been incredibly successful at spotting potentially habitable-zone planets since 2009, lost its control mechanism this month and has been rendered largely inactive.

Submission + - 10 things you may not know about Ethernet (networkworld.com)

coondoggie writes: Ethernet's value to networking and IT is well established over the past 40 years. But did you know that "Ethernet" refers to two slightly different ways of sending information between endpoints on a LAN? That and some other perhaps lesser known facts about this 40-year-old technology.
