A US technology firm has developed a drone that is able to aim and fire at enemies while flying in mid-air.The Tikad drone, developed by Duke Robotics, is armed with a machine-gun and a grenade launcher.The gun can be fired only by remote control, and is designed to reduce military casualties by cutting the number of ground troops required.But campaigners warn that in the wrong hands, it will make it easier to kill innocent people.The Tikad drone, available for private sale at an undisclosed price, has won a security innovation award from the US Department of Defense, and there is interest from several military forces around the world, including Israel, reports Defense One.

MENLO PARK, Calif. — It’s not easy being the first and only Fox News host in Silicon Valley.But Steve Hilton, a tech entrepreneur who was once chief adviser to former Prime Minister David Cameron of Britain, added that role to his résumé in June.Now every week, Mr. Hilton flies from the home he shares with his high-profile tech executive wife, Rachel Whetstone, in Silicon Valley’s billionaire enclave of Atherton, Calif., to Fox’s studios in Los Angeles to host “The Next Revolution With Steve Hilton.” Fox News markets the Sunday night program as exploring “the impact of the populist movement.”

SHANGHAI — Facebook and many of its apps have been blocked in China for years. To change that, Mark Zuckerberg has made a big point of meeting with Chinese politicians, reading stodgy Communist Party propaganda, studying Mandarin and — perhaps more daunting — speaking it in public.Now the social network is trying a different way into China: by authorizing the release of a new app there that does not carry the Facebook name.Facebook approved the May debut of a photo-sharing app, called Colorful Balloons, in China, according to a person with knowledge of the company’s plans, who declined to be named because the information is politically sensitive. The app, whoch has not previously been reported, shares the look, function and feel of Facebook’s Moments app. It was released through a separate local company and without any hint that the social network is affiliated with it.

The Google engineer who was fired last week over his memo wrote that most women were biologically unsuited to working in tech because they were more focused on “feelings and aesthetics than ideas” and had “a stronger interest in people rather than things.”Many scientists have said he got the biology wrong. But the job requirements of today’s programmers show he was also wrong about working in tech.In fact, interpersonal skills like collaboration, communication, empathy and emotional intelligence are essential to the job. The myth that programming is done by loner men who think only rationally and communicate only with their computers harms the tech industry in ways that cut straight to the bottom line.
