SAN FRANCISCO, Sept. 22 (Xinhua) -- Former eBay Chief Executive Officer and California governor candidate Meg Whitman on Thursday was named Hewlett-Packard's new CEO, replacing Leo Apotheker who served 11 months on the job."We are fortunate to have someone of Meg Whitman's caliber and experience step up to lead HP," said the California-based company in a statement."We are at a critical moment and we need renewed leadership to successfully implement our strategy and take advantage of the market opportunities ahead," said the troubled tech giant.It noted that the job of the HP CEO now requires additional attributes to successfully execute on the company's strategy, adding Whitman "has the right operational and communication skills and leadership abilities to deliver improved execution and financial performance.""I am honored and excited to lead HP. I believe HP matters -- it matters to Silicon Valley, California, the country and the world," said Whitman in a statement.Whitman, 55, joined the HP board in January and served as president and CEO of eBay from 1998 to 2008, when she led the company through its initial public offering and massive growth.During her last years at eBay, she is blamed for not being able to halt the sales slowdown and overpaying for the 2005 acquisition of Skype with 4.1 billion dollars. In 2009, Skype was sold by eBay at a valuation of 2.75 billion dollars.Whitman won the Republican nomination for governor of California in 2010. She lost the election to Gov. Jerry Brown after spending more than 140 million dollars of her own fortune on the campaign. EnditemHP said the appointments are effective immediately, following the decision that Apotheker stepped down as president and CEO and resigned as a director of the company.Multiple U.S. media reported on Wednesday that Apotheker was to be ousted, sending HP shares soaring on the market and in the after-hour trading.Apotheker, 58, was named HP CEO 11 months ago to replace Mark Hurd, who was ousted due to a scandal over a personal relationship with a company contractor and then became co-president of Oracle. Before HP, Apotheker had served as CEO of German software giant SAP for 10 months.On Aug. 18, Apotheker announced that HP will shut down its mobile business, spin off its core personal computer business and transfer into a cloud-based software and services provider for businesses including a 10.3 billion-dollar acquisition of British software company Autonomy.Shares of the company plunged 20 percent the following day, the worst one-day loss since Black Monday in 1987.On Sept. 30, 2010, the day before Apotheker's appointment as HP CEO, the tech giant's stock closed at 42.04 dollars. On Tuesday, the price closed at 22.47 dollars, a decrease of 46.6 percent in less than a year.On Monday, HP was reported to begin sending over 500 employees pink slips in the WebOS division, after announcing to stop making WebOS devices in August.

LOS ANGELES, July 22 (Xinhua) -- Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe, NASA's Jet Propulsion Laboratory (JPL) said on Friday.The water, equivalent to 140 trillion times all the water in the world's ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away, according to JPL in Pasadena, California."The environment around this quasar is very unique in that it's producing this huge mass of water," said Matt Bradford, a scientist at JPL. "It's another demonstration that water is pervasive throughout the universe, even at the very earliest times. "This artist's concept illustrates a quasar, or feeding black hole, similar to APM 08279+5255, where astronomers discovered huge amounts of water vapor. Gas and dust likely form a torus around the central black hole, with clouds of charged gas above and below. X-rays emerge from the very central region, while thermal infrared radiation is emitted by dust throughout most of the torus. While this figure shows the quasar's torus approximately edge-on, the torus around APM 08279+5255 is likely positioned face-on from our point of view.A quasar is powered by an enormous black hole that steadily consumes a surrounding disk of gas and dust. As it eats, the quasar spews out huge amounts of energy. Both groups of astronomers studied a particular quasar called APM 08279+5255, which harbors a black hole 20 billion times more massive than the sun and produces as much energy as a thousand trillion suns.Astronomers expected water vapor to be present even in the early, distant universe, but had not detected it this far away before. There's water vapor in the Milky Way, although the total amount is 4,000 times less than in the quasar, because most of the Milky Way's water is frozen in ice. Water vapor is an important trace gas that reveals the nature of the quasar. In this particular quasar, the water vapor is distributed around the black hole in a gaseous region spanning hundreds of light-years in size (a light-year is about six trillion miles).Its presence indicates that the quasar is bathing the gas in X- rays and infrared radiation, and that the gas is unusually warm and dense by astronomical standards, JPL said.Although the gas is at a chilly minus 63 degrees Fahrenheit ( minus 53 degrees Celsius) and is 300 trillion times less dense than Earth's atmosphere, it's still five times hotter and 10 to 100 times denser than what's typical in galaxies like the Milky Way, said JPL.Measurements of the water vapor and of other molecules, such as carbon monoxide, suggest there is enough gas to feed the black hole until it grows to about six times its size, JPL said.Whether this will happen is not clear, the astronomers say, since some of the gas may end up condensing into stars or might be ejected from the quasar.Bradford's team made their observations starting in 2008, using an instrument called "Z-Spec" at the California Institute of Technology's (Caltech's) Submillimeter Observatory, a 33-foot (10- meter) telescope near the summit of Mauna Kea in Hawaii. Follow-up observations were made with the Combined Array for Research in Millimeter-Wave Astronomy (CARMA), an array of radio dishes in the Inyo Mountains of Southern California.The second group, led by Dariusz Lis, senior research associate in physics at Caltech and deputy director of the Caltech Submillimeter Observatory, used the Plateau de Bure Interferometer in the French Alps to find water. In 2010, Lis's team serendipitously detected water in APM 8279+5255, observing one spectral signature.Bradford's team was able to get more information about the water, including its enormous mass, because they detected several spectral signatures of the water, according to JPL.

SAN FRANCISCO, Aug. 17 (Xinhua) -- Microsoft's cloud-based software Microsoft Office 365 on Wednesday experienced its first major outage since its introduction in late June."At approximately 11:30 a.m. PDT, Microsoft became aware of a networking issue affecting customers of some Microsoft services hosted out of one of our North American data centers," said Steven Gerri, general manager for Microsoft Global Foundation Services, in a statement"We apologize for the inconvenience that Office 365 outage has caused today. We are working on resolving the issue," the software giant said via Twitter.Outages were reported in Chicago, Denver and New York City among other locations. According to tweets from affected users, they were unable to access their email and managers were unable to manage accounts.The outage lasted approximately five hours and services have been restored for the moment.According to Microsoft service-level agreement, Microsoft guarantees a 99.9 percent level of uptime. If it fails to reach 99.9 percent uptime, users are eligible for 25 percent service credit.As more industry giants try to entice users to move to the "cloud," a term refers to the management and provision of applications and data over the Internet, the downtime again reminds cloud computing users that they must prepare to deal with outages and rethink their dependency on the service, analysts said.Amazon has suffered two major cloud outages earlier this month and back in April, impacting some of its high-profile users like movie streaming service Netflix and location-based social networking Foursquare.Analysts recommend cloud users to store data with multiple service providers to minimize the risk and limit their dependency on cloud services for business-critical processes.Available in 40 countries and regions since June 28, Office 365, which Microsoft CEO Steve Ballmer said is "where Microsoft office meets the cloud," combines Microsoft Office, SharePoint Online, Exchange Online and Lync Online into a single cloud-based package for business users.

LOS ANGELES, July 5 (Xinhua) -- NASA's Juno spacecraft is 30 days away before its first launch window opens, the Jet Propulsion Laboratory (JPL) announced on Tuesday."One month from today, our first launch window opens at 11:34 a. m. EDT (8:34 a.m. PDT) and lasts 69 minutes," said Jan Chodas, Juno project manager from NASA's JPL in Pasadena, Los Angeles."Our primary launch period is 22 days long, and so if weather or other issues come up on Aug. 5, we have 21 more days to get Juno flying. Once we get Juno into space, it's a five-year cruise to Jupiter.""The launch window is the length of time allotted every day for an attempt to launch the spacecraft," said Chodas. "The launch period is the period of time in days when everything is in the right place to get your mission off to the right start."For a mission like Juno, getting everything in the right place includes considering the size of the rocket and spacecraft, where our home planet -- and in particular Juno's launch pad -- is pointed at any moment, and its location in space relative to other celestial objects like Juno's final target, Jupiter.Juno is scheduled to launch aboard a United Launch Alliance Atlas V rocket from pad 41-C at the Cape Canaveral Air Force Station, Florida.The solar-powered spacecraft will orbit Jupiter's poles 33 times to find out more about the gas giant's origins, structure, atmosphere and magnetosphere and investigate the existence of a solid planetary core.JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio.The Juno mission is part of the New Frontiers Program managed at NASA's Marshall Space Flight Center in Huntsville, Alaska. Lockheed Martin Space Systems, Denver, built the spacecraft.

BEIJING, July 5 (Xinhuanet) -- Facebook CEO Mark Zuckerberg confirmed that he has signed up to Google+, the new social networking platform from Google, according to media reports Tuesday.Launched last month, Google+ is the Internet giant's latest foray into social networking.Zuckerberg confirmed that the profile with his name on Google+ belongs to him only, and said, "Why are people so surprised that I'd have a Google account?" Facebook CEO Mark Zuckerberg reacts after unveiling a new messaging system during a news conference in San Francisco, California November 15, 2010.In social networking field, it is rare for someone to join the rival's platform, therefore, Zuckerberg's move is considered strange.But interestingly, Zuckerberg has more followers than Google founders Larry Page and Sergey Brin, and even Vic Gundotra, the man behind Google+, with over 21,000 people.Besides Google+, Zuckerberg also has an account on Twitter, though it has not been updated for some time.
