Uber's rocky year: Travis Kalanick's resignation is just the latest thing Uber co-founder Travis Kalanick resigned as chief executive of the ride-hailing giant Wednesday, pushed out by investors just a week after he announced he was going on an indefinite leave of absence. The San Francisco startup, valued at near $70 billion, has been rocked this year by allegations of a corrosive culture that allowed sexual harassment and other bad behavior to go unchecked for years. Uber drivers have their say about Kalanick's resignation Column: With Travis Kalanick out, we'll see the real value of Uber -- and it won't be pretty Column: With Travis Kalanick out, we'll see the real value of Uber -- and it won't be pretty Facing mounting investor pressure brought on by a torrent of scandals, Travis Kalanick, co-founder and chief executive of ride-hailing company Uber, resigned -- just a week into a leave of absence meant to quell concerns about his management style. The New York Times reported that five of Uber's major investors demanded Kalanick's immediate resignation because the company needed a change in leadership. Kalanick reached his decision to resign after hours of talks with some of the investors.

Languages, like human bodies, come in a variety of shapes--but only to a point. Just as people don't sprout multiple heads, languages tend to veer away from certain forms that might spring from an imaginative mind. For example, one core property of human languages is known as duality of patterning: meaningful linguistic units (such as words) break down into smaller meaningless units (sounds), so that the words sap, pass, and asp involve different combinations of the same sounds, even though their meanings are completely unrelated. It's not hard to imagine that things could have been otherwise. In principle, we could have a language in which sounds relate holistically to their meanings--a high-pitched yowl might mean "finger," a guttural purr might mean "dark," a yodel might mean "broccoli," and so on.

Machine learning gets a lot of buzz these days, usually in connection with big data and artificial intelligence (AI). But what exactly is it? Broadly speaking, machine learners are computer algorithms designed for pattern recognition, curve fitting, classification and clustering. The word learning in the term stems from the ability to learn from data. Machine learning is also widely used in data mining and predictive analytics, which some commentators loosely call big data.

Uber CEO Travis Kalanick resigned late Tuesday night from the company he cofounded in 2009. While he'll remain on the board of directors, Kalanick's departure comes after months, if not years, of reports of a toxic workplace culture, cutthroat business tactics, and the occasional public embarrassment. It's not clear who will replace Kalanick. But what is clear is that this person will have a lot to correct. Here's a timeline of many, many upheavals that led the $69-billion startup to this crisis point.

With major technology companies and startups seriously embracing Cloud strategies, now is the perfect time to attend 21st Cloud Expo, October 31 - November 2, 2017, at the Santa Clara Convention Center, CA, and June 12-14, 2018, at the Javits Center in New York City, NY, and learn what is going on, contribute to the discussions, and ensure that your enterprise is on the right path to Digital Transformation. Every Global 2000 enterprise in the world is now integrating cloud computing in some form into its IT development and operations. Midsize and small businesses are also migrating to the cloud in increasing numbers. Companies are each developing their unique mix of cloud technologies and services, forming multi-cloud and hybrid cloud architectures and deployments across all major industries. Cloud-driven thinking has become the norm in financial services, manufacturing, telco, healthcare, transportation, energy, media, entertainment, retail and other consumer industries, and the public sector.

People could soon travel from London to Edinburgh in eight minutes, claims Hyper Chariot, a company that has announced its intention to build an extremely ambitious new transport system. It would be capable of reaching speeds of 4,000mph, and could also be emission-free and 100 per cent solar-powered, "thanks to the use of solar panels mounted on the outside of the tunnels", according to the company. It says it wants the network to be fully operational by 2040, and plans to unveil a working'proof of concept' demonstrator, called'The Velocitator', in 2021. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph. The giant human-like robot bears a striking resemblance to the military robots starring in the movie'Avatar' and is claimed as a world first by its creators from a South Korean robotic company Waseda University's saxophonist robot WAS-5, developed by professor Atsuo Takanishi and Kaptain Rock playing one string light saber guitar perform jam session A man looks at an exhibit entitled'Mimus' a giant industrial robot which has been reprogrammed to interact with humans during a photocall at the new Design Museum in South Kensington, London Electrification Guru Dr. Wolfgang Ziebart talks about the electric Jaguar I-PACE concept SUV before it was unveiled before the Los Angeles Auto Show in Los Angeles, California, U.S The Jaguar I-PACE Concept car is the start of a new era for Jaguar.

NASA's Mars Reconnaissance Orbiter has spotted all sorts of strange features on the Martian surface, from deep pits to reptilian-looking craters. But, in a recent observation, the instrument caught a glimpse of something far more familiar. A stunning new image shows a look at the rocky mountainside terrain of Mars' Mount Sharp – and, appearing as a bright blue speck at the center, the Curiosity rover can be seen as it presses onward in its uphill mission.

There are few names in the world of tech more trusted than Nokia. Many of us grew up with the brand as the go-to company for the easiest-to-use, most reliable, best-designed mobile phones. And French company Withings in recent years has built a fearsome reputation for brilliant home appliances that had wireless connectivity before other companies even got into the smart home game.

"Artificial intelligence may take a lot of jobs away. If we don't give simple and easy technology products for small businesses, most of them can't survive in 10 years. If small businesses can't survive, we can't survive," said Ma, speaking in Detroit at the Gateway 17 conference for entrepreneurs. "It's going to be painful. Some people who catch the wave will be rich, will be more successful. For some people, it will be more painful. The government, you know, the world is going to be data. The people will now have more data than the bosses," he said in an interview with CNBC.

Yoshua Bengio has never been one to take sides. As one of the three intellects who shaped the deep learning that now dominates artificial intelligence, he has been catapulted to stardom. It's a field so new the people who can advance it fit into one room together, and everyone--from tech startups to multinational conglomerates and the department of defense--wants a share of their minds. But while his peer scientists Yann LeCun and Geoffrey Hinton have signed on to Facebook and Google, respectively, Bengio, 53, has chosen to continue working from his small third-floor office on the hilltop campus of the University of Montreal. "I want to remain a neutral agent," he says as he sips rust-colored licorice water, which he pours from a carafe that acts as a weight for the mess of papers cluttering his desk. Sign up to get Backchannel's weekly newsletter. Like the nuclear scientists of the last century, Bengio understands that the tools he's invented are powerful beyond measure and must be cultivated with great forethought and widespread consideration. "We don't want one or two companies, which I will not name, to be the only big players in town for AI," he says, raising his eyebrows to indicate that we both know which companies he means. One eyebrow is in Menlo Park; the other is in Mountain View. That's why Bengio has recently chosen to forego his neutrality, signing on with Microsoft.
