    “When it became known that the NSA was spying on people all around the world, everybody was upset. This actor [Facebook] is doing the very same thing, albeit in a different way,” he said.

  • Facebook CEO Zuckerberg to take two months of paternity leave


    Facebook Inc (FB.O) Chief Executive Officer Mark Zuckerberg said on Friday he will take two months of paternity leave after his daughter's birth, a strong statement from one of the busiest and most powerful U.S. executives on the importance of family time.Silicon Valley technology firms have rushed to extend parental leave allowances and other benefits in an attempt to recruit and retain talent, but many workers do not take advantage for fear of falling behind at work or missing out on promotions.

    Facebook, the world's biggest online social network, allows its U.S. employees to take up to four months of paid maternity or paternity leave, which can be used all at once or throughout the first year of their child's life, a policy which is generous by U.S. standards. Zuckerberg announced in July that he and his wife, Priscilla Chan, were expecting a baby girl.

  • Phones Require 'bed time mode' to protect sleep


    [ Habesha2day]  Smart phones, tablets and e-readers should have an automatic "bedtime mode" that stops them disrupting people's sleep, says a leading doctor.

    Prof Paul Gringras argued the setting should filter out the blue light that delays the body clock and keeps people awake later into the night. The doctor, from Evelina Children's Hospital in London, said every new model was "bluer and brighter".the doctor said manufacturers needed to show more responsibility. As it gets darker in the evening, the body starts to produce the Melatonin which helps people nod off.


    Certain wavelengths of light, those at the blue-green end of the spectrum, can break up the system.Prof Gringras was part of a study, published in Frontiers in Public Health, analyzing the light emitted by devices.It concluded there was a clear trend for new devices to be bigger, brighter, have higher levels of contrast and emit more blue light.



    The professor of children's sleep medicine told the BBC News website: "That is great for use in the day, but awful for use at night.There is converging data to say if you are in front of one of these devices at night-time it could prevent you falling asleep by an extra hour.He said some sleep-aware apps had already been designed to reduce blue-green light emissions.


    And that a bedtime mode could automatically filter out the blue as software such as f.lux already does.He said there needed to be "more responsibility from manufacturers" and the "key is to automate it".Prof Gringras added: "It's not good enough to say do less and accept this is the world we live in, they're fun devices but we do need some protection on what they do at night-time."

  • The Ethiopian man who built his own plane from scratch

    (CNN)On June 15 2015, Asmelash Zeferu sat at the end of a runway, over a decade of work malfunctioning around him. The Ethiopian amateur pilot was as shattered as his propeller. There had been doubters, those who had called him "mad." Many had turned up at the airfield, 40 kilometers north of Addis Ababa, to watch him take off. He had been ready to prove them wrong.

    Asmelash Zerfu and his home made plan

    But it wasn't to be. The propeller, hand-crafted from laminated wood, had broken. The cause? High amounts of friction, taking with it the smoke exit system too. It was time to return to the drawing board and now, following months of repairs and remodeling, Zeferu is ready to line up on the runway once more.
