Two suspected al Qaeda militants killed in Yemen drone strike

ADEN (Reuters) - At least two suspected Islamist militants were killed in a drone missile strike in Yemen's southern Shabwa province, the latest in a surge since Washington warned of possible attacks by al Qaeda in the region.

At least 37 people have been killed in just over two weeks in a campaign targeting insurgents linked to Al Qaeda in the Arabian Peninsula (AQAP), described by U.S. officials as the most dangerous branch of the global jihadi network.

That campaign has been stepped up after intercepted communication between AQAP leader, Nasser al Wuhayshi and Ayman al-Zawahri, head of al Qaeda, along with other intelligence prompted Washington to close 19 U.S. embassies this month.

"The car was completely obliterated and the two men inside it were killed," a local official said, adding the strike happened late on Monday. He gave no further details.

Yemen is one of a handful of countries where Washington acknowledges using drones, although it does not comment publicly on the practice.

Security in Yemen is of regional and global importance.

AQAP has previously plotted unsuccessfully to attack international airliners and is seen in Washington as a potential threat to Yemen's neighbor Saudi Arabia, the world's top oil exporter, and Red Sea oil tankers.

On Monday, AQAP leader Wuhayshi said he would free jailed Islamist militants soon.

SAN JOSE, Calif. (AP) ? Twice as fast as an airplane, cheaper than a bullet train and completely self-powered: that's the mysterious transportation system that inventor and entrepreneur Elon Musk is promising to reveal design plans for Monday.

Musk has been dropping hints about his "Hyperloop" system for more than a year during public events, mentioning that it could never crash, would be immune to weather and would move people from Los Angeles to San Francisco in half an hour.

Coming from almost anyone else, the hyperbole would be hard to take seriously. But billionaire Musk ? who sold his first computer program, a $500 space game called Blastar, at age 12 ? has earned his reputation as an inventor and entrepreneur, co-founding online payment firm PayPal, electric luxury carmaker Tesla Motors Inc. and rocket-building company SpaceX.

During a Tesla earnings call Thursday, Musk said he would reveal plans for the Hyperloop on Monday. But he said he is too focused on other projects to consider actually building it.

"I think I kind of shot myself by ever mentioning the Hyperloop," he said. "I don't have any plans to execute, because I must remain focused on SpaceX and Tesla."

He said he would fulfill his commitment to publishing a design, and he said he invites critical feedback after its release Monday to "see if the people can find ways to improve it." It will be an open-source design, meaning anyone can use it and modify it.

Also Thursday, Musk said during a Google Hangout with Sir Richard Branson about entrepreneurship, "It does involve a tube, but not a vacuum tube."

His hints and promises have prompted a flurry of online speculation.

Canadian John Gardi, a self-described "tinkerer," posted online and tweeted his conjecture a few weeks ago to Musk.

"I believe that Hyperloop is merely a modern day version of the pneumatic tubes used in banks, stores, and industry to move money and small items over long distances or to other floors of a building," he said.

Musk responded, "Your guess is the closest I've seen anyone guess so far."

Voice over IP is ? | What is this ? - Top definitions

Voice over IP is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, IP communications, and broadband phone service.

The term Internet telephony specifically refers to the provisioning of communications services over the public Internet, rather than via the public switched telephone network (PSTN). The steps and principles involved in originating VoIP telephone calls are similar to traditional digital telephony, and involve signaling, channel setup, digitization of the analog voice signals, and encoding. Instead of being transmitted over a circuit-switched network, however, the digital information is packetized and transmission occurs as Internet Protocol (IP) packets over a packet-switched network. Such transmission entails careful considerations about resource management different from time-division multiplexing (TDM) networks.

Early providers of voice over IP services offered business models and technical solutions that mirrored the architecture of the legacy telephone network. Second generation providers, such as Skype, have built closed networks for private user bases, offering the benefit of free calls and convenience, while potentially charging for access to other communication networks, such as the PSTN. This has limited the freedom of users to mix-and-match third-party hardware and software. Third generation providers, such as Google Talk have adopted the concept of federated VoIP ? which is a departure from the architecture of the legacy networks. These solutions typically allow dynamic interconnection between users on any two domains on the Internet when a user wishes to place a call.

However, a majority of DSL providers use only one VC for each customer, even those with bundled VoIP service. Every Ethernet frame must be completely transmitted before another can begin. If a 2nd VC were established, given high priority and reserved for VoIP, then a low priority data packet could be suspended in mid-transmission and a VoIP packet sent right away on the high priority VC. Then the link would pick up the low priority VC where it left off. Because ATM links are multiplexed on a cell-by-cell basis, a high priority packet would have to wait at most 53 byte times to begin transmission. There would be no need to reduce the interface MTU and accept the resulting increase in higher layer protocol overhead, and no need to abort a low priority packet and resend it later.

OUYA's Free The Games Fund now live, offers $1 million toward crowdfunded titles

OUYA has launched its promised fund-matching campaign to spur development of games for its recently launched Android console. Now known as the Free the Games Fund, the effort rewards successful Kickstarter campaigns with a matching $50,000 to $250,000; OUYA will back as many games as its $1 million pool allows. There are a few conditions, of course. Producers have to meet that $50,000 minimum, end their campaigns within the next year and agree to a six-month OUYA exclusive. The console maker will also stagger payments across the development cycle, although the company promises an additional $100,000 to the most successful project. If you're looking for help in building a game and are willing to take a chance on a young platform, full details of the fund await at the source link.
