Solar-powered plane circles globe, returns to UAE

2016-07-26 08:23:42

ABU DHABI A solar-powered aircraft successfully completed the first fuel-free flight around the world on Tuesday, returning to Abu Dhabi after an epic 16-month voyage and demonstrating the potential of renewable energy.The plane, Solar Impulse 2, touched down in the United Arab Emirates capital at 0005 GMT (0405 local time) on Tuesday. It first took off from Abu Dhabi on March 9, 2015, beginning a landmark journey of about 40,000 km (24,500 miles) around the globe and nearly 500 hours of flying. Unfavorable weather at times hindered smooth flying, causing the plane to be grounded for months in some countries. Swiss explorers Bertrand Piccard and André Borschberg, Solar Impulse founders and pilots, took turns piloting the aircraft with a wingspan larger than a Boeing 747 and weighing only as much as a family car. The Swiss team is campaigning to bolster support for clean energy. The propeller-driven aircraft's four engines are powered exclusively by energy collected from more than 17,000 solar cells built the plane's wings. Excess energy is stored in four batteries during daylight hours to keep the plane flying after dark.Over its entire mission, Solar Impulse 2 cruised at altitudes of up to 9,000 meters and at an average speed of between 45 and 90 km (12.5 and 25 miles) per hour. The plane had 16 stopovers along the way including in Oman, India, Myanmar, China, Japan, the United States, Spain and Egypt. Abu Dhabi’s green energy firm Masdar is the official host partner of Solar Impulse 2. Oil-rich Abu Dhabi is investing billions in industry, tourism and renewables to diversify its economy away from oil. (Reporting by Stanley Carvalho, editing by Sami Aboudi and Hugh Lawson)

Yahoo reports lackluster results as sale looms

2016-07-19 06:48:57

Yahoo Inc's (YHOO.O) quarterly earnings fell short of Wall Street expectations on Monday in what may be the company's last financial report before it sells its core business.Yahoo reported adjusted earnings of 9 cents per share, short of the 10 cents that analysts expected. It also announced a $482 million write-down on the value of Tumblr, the social media service that it acquired in 2013 for $1.1 billion.Yahoo is in the process of auctioning off its search and advertising business, and is expected to choose a winner this week. The company said its board has made "great progress on strategic alternatives" but did not comment further on the auction process.Verizon Communications Inc and AT&T Inc are said to be in the running to acquire the core business, along with private equity firm TPG Capital and a consortium led by Quicken Loans founder Dan Gilbert and backed by billionaire Warren Buffett.Yahoo also owns large stakes in Chinese ecommerce giant Alibaba and Yahoo Japan, which are worth far more than the company's internet business.Monday's earnings report showed the continued slide in Yahoo's business during the protracted sale process. After the Tumblr write-down, the company posted a net loss of $439.9 million, or 46 cents per share, compared with a loss of $21.6 million, or 2 cents per share, a year earlier. Although total revenue rose to $1.31 billion from $1.24 billion a year earlier, the seeming improvement was the result of a change in the way the cost of acquiring traffic is counted. After deducting fees paid to partner websites for traffic, revenue fell to $841.2 million from $1.04 billion.Estimating that Tumblr is worth "nothing" at this point, Ross Gerber, cofounder and CEO of Gerber Kawasaki Wealth and Investment Management, said potential buyers were likely bidding lower than Yahoo believes it is worth."I can't imagine why the sale process is taking so long, the only thing I can think of is it's being overpriced. This report doesn't further create an impression that paying up for these assets has any value," Gerber said. Revenue in the company's emerging businesses, which Chief Executive Officer Marissa Mayer calls Mavens - mobile, video, native and social advertising - showed some life, rising 25.7 percent to $504 million in the second quarter ended June 30. But the improvement in Mavens was offset by decreases in gross search revenue that is only expected to get worse, said B. Riley & Co analyst Sameet Sinha. Gross search revenue for the quarter was $765 million, down 17 percent from the same period last year. "This is supposed to be the growth engine of the company, and at best it was up slightly year over year. That shows that even in high-growth categories like mobile and native they're losing their search impact," he said. JMP Securities analyst Ronald Josey said search revenues are a significant portion of Yahoo's overall revenues and their continued decline could definitely be a factor in the sale negotiations. "If search continues to decline as much as it has, that's something that's going to be called into question," he said.In a conference call, Yahoo Chief Financial Officer Ken Goldman touted the company's cost-cutting efforts.“Through excellent expenditure management of cost and capital, we achieved above the high-end of our guidance on adjusted EBITDA and significantly increased cash flow,” he said, referring to earnings before interest, taxes, depreciation and amortization.Yahoo's shares were little changed at $37.92 in trading after the bell.

Split and Clone Editor Views in Eclipse

2016-07-12 04:24:10

Sometimes it is all about knowing the simple tricks in Eclipse which make life easier. Like this one: How to have a split editor view so I can edit multiple different sections of a source file.That feature is present in Eclipse Luna and afterwards, but because there is no icon in the view itself as in Microsoft Word, I have found that many do not know about this useful feature. The screensthots below are for Eclipse Luna.Split Editor ViewTo split an editor view, I have it selected (to be active), then I use the menu ‘Toggle Split Editor’:I can split it horizontal:Or in a vertical way:I can use the mouse to resize the split area:To remove the split, simply use the menu or shortcut again:Clone Editor ViewThe other useful function is to clone an Editor view:This creates a clone of that view:To ‘undo’ the cloning, I close the new editor view.SummarySplitting and Cloning gives me a way to edit the same source file in different portions of that file. The commands to Clone and Split is under the Window > Editor menu.Happy Cloning and Splitting!

NASA's Juno spacecraft loops into orbit around Jupiter

2016-07-05 13:49:44

CAPE CANAVERAL, Fla. NASA's Juno spacecraft capped a five-year journey to Jupiter late Monday with a do-or-die engine burn to sling itself into orbit, setting the stage for a 20-month dance around the biggest planet in the solar system to learn how and where it formed.“We’re there. We’re in orbit. We conquered Jupiter,” lead mission scientist Scott Bolton, with the Southwest Research Institute in San Antonio, told reporters on Tuesday. “Now the fun begins.”Juno will spend the next three months getting into position to begin studying what lies beneath Jupiter’s thick clouds and mapping the planet’s gargantuan magnetic fields.Flying in egg-shaped orbits, each one lasting 14 days, Juno also will look for evidence that Jupiter has a dense inner core and measure how much water is in the atmosphere, a key yardstick for figuring out how far away from the sun the gas giant formed.Jupiter's origins, in turn, affected the development and position of the rest of the planets, including Earth and its fortuitous location conducive to the evolution of life.“The question I’ve had my whole life that I’m hoping we get an answer to is ‘How’d we get here?’ That’s really pretty fundamental to me,” Bolton said.Jupiter orbits five times farther from the sun than Earth, but it may have started out elsewhere and migrated, jostling its smaller sibling planets as it moved. Jupiter's immense gravity also diverts many asteroids and comets from potentially catastrophic collisions with Earth and the rest of the inner solar system.Launched from Florida nearly five years ago, Juno needed to be precisely positioned, ignite its main engine at exactly the right time and keep it firing for 35 minutes to become only the second spacecraft to orbit Jupiter.If anything had gone even slightly awry, Juno would have sailed helplessly past Jupiter, unable to complete a $1 billion mission. The risky maneuver began as planned at 11:18 p.m. EDT/0318 Tuesday GMT as Juno soared through the vacuum of space at more than 160,000 mph (257,500 kph).NASA expects Juno to be in position for its first close-up images of Jupiter on Aug. 27, the same day its science instruments are turned on for a test run.Only one other spacecraft, Galileo, has ever circled Jupiter, which is itself orbited by 67 known moons. Bolton said Juno is likely to discover even more.Seven other U.S. space probes have sailed past the gas giant on brief reconnaissance missions before heading elsewhere in the solar system. The risks to the spacecraft are not over. Juno will fly in highly elliptical orbits that will pass within 3,000 miles (4,800 km) of the tops of Jupiter's clouds and inside the planet's powerful radiation belts.Juno's computers and sensitive science instruments are housed in a 400-pound (180-kg) titanium vault for protection. But during its 37 orbits around Jupiter, Juno will be exposed to the equivalent of 100 million dental X-rays, said Bill McAlpine, radiation control manager for the mission.The spacecraft, built by Lockheed Martin, is expected to last for 20 months. On its final orbit, Juno will dive into Jupiter's atmosphere, where it will be crushed and vaporized.Like Galileo, which circled Jupiter for eight years before crashing into the planet in 2003, Juno's demise is designed to prevent any hitchhiking microbes from Earth from inadvertently contaminating Jupiter's ocean-bearing moon Europa, a target of future study for extraterrestrial life.

Google beats children's web privacy appeal, Viacom must face one claim

2016-06-27 19:24:29

A federal appeals court on Monday said Google and Viacom need not face a nationwide lawsuit claiming they illegally tracked the activity of children under the age of 13 who watched videos and played video games on the Nickelodeon website.The 3rd U.S. Circuit Court of Appeals in Philadelphia largely upheld a January 2015 lower court ruling dismissing claims that Google, which is a unit of Alphabet Inc, and Viacom Inc violated the federal Video Privacy Protection Act by planting "cookies" on children's computers. But the appeals court also revived one privacy claim against Viacom, which alleged that the company promised not to collect personal information about children but did so anyway.
