Twitter Inc has hired an advertising executive from Google Inc to head its retail division, as the online messaging company ramps up hiring and works to expand its business ahead of an initial public offering, Bloomberg reported on Wednesday. 

J.J. Hirschle, who directed media and entertainment advertising at Google, will be responsible for the team selling advertising products to retail companies, the agency said, citing Will Stickney, a spokesman for Twitter. 

Hirschle is to start on Oct. 28, the same day Twitter is expected to kick off its investor roadshow where it will pitch its offering to Wall Street before shares start trading in mid-November. 

Since Twitter was spun out of a struggling San Francisco startup in 2006, it has grown to about 2,300 employees as of September. Twitter could not immediately be reached for comment by Reuters outside of regular US business hours.

Facebook to let teens share their posts with with anyone on internet

0 comments


Facebook has loosened its privacy rules for teenagers as a rising debate swirls over online threats to children from bullies and sexual predators. 

The move, announced Wednesday, allows teenagers to post status updates, videos and images that can be seen by anyone, not just their friends or people who know their friends. 

While Facebook described the change as giving teenagers, ages 13 to 17, more choice, big money is at stake for the company and its advertisers. Marketers are keen to reach impressionable young consumers, and the more public information they have about those users, the better they are able to target their pitches. 

"It's all about monetization and being where the public dialogue is," said Jeff Chester, executive director of the Center for Digital Democracy, a group that lobbies against marketing to children. "To the extent that Facebook encourages people to put everything out there, it's incredibly attractive to Facebook's advertisers." 

But that public dialogue now includes youths who are growing up in a world of social media and, often, learning the hard way that it can be full of risks. Parents, too, are trying to help their children navigate the raucous online world that holds both promise and peril. 

"They're hitting kids from a neurological weak spot. Kids don't have the same kind of impulse control that adults do," said Emily Bazelon, a journalist and author of the book "Sticks and Stones: Defeating the Culture of Bullying and Rediscovering the Power of Character and Empathy." 

Facebook said numerous other sites and mobile apps, from big players like Twitter and Instagram to lesser-known ones like ask.fm and Kik Messenger, allowed teenagers to express themselves publicly. 

"Across the Web, teens can have a very public voice on those services, and it would be a shame if they could not do that on Facebook," Nicky Jackson Colaco, Facebook's manager of privacy and public policy, said in a phone interview. 

But unlike those other services, Facebook requires users to post under their real identities, which some privacy advocates said would make it much more difficult to run away from stupid or thoughtless remarks. 

"It's risky to have teenagers posting publicly," Bazelon said. "The kids who might be the most likely to do that might not have the best judgment about what they post." 

Facebook also said it had made the change to let its most knowledgeable users - socially active teenagers like musicians and humanitarian activists - reach a wider audience the way they can on blogs and rival services like Twitter. 

Facebook changed another aspect of its rules for teenagers, for which it drew praise. By default, new accounts for teenagers will be set up to share information only with friends, not friends of friends as before. Colaco said the company would also educate teenagers about the risks of sharing information and periodically remind them, if they 

make public posts that everyone can see what they are sharing. 

But fundamentally, Facebook wants to encourage more public sharing, not less. 

The company, which has about its 1.2 billion users worldwide, is locked in a battle with Twitter and Google to attract consumer advertisers like food, phone and clothing companies. Those brands want to reach people as they engage in passionate public conversation about sports, television, news and live events. 

Twitter, which has been emphasizing its virtue as a real-time public platform as it prepares to make a public offering of stock next month, has been particularly effective at persuading marketers that it is the best way to reach audiences talking about the hottest television show or the week's National Football League games. 

Facebook is reducing children's privacy even as lawmakers are moving in the opposite direction, grappling with difficult issues like online bullying and the question of whether to allow people to erase their digital histories. In September, a 12-year-old Florida girl, Rebecca Ann Sedwick, committed suicide after extensive online bullying on Facebook, Kik Messenger and ask.fm. This month, Florida authorities charged two youngsters with aggravated stalking in the case. 

Gov. Jerry Brown of California recently signed a law that allows residents to erase online indiscretions posted while they were teenagers. And European lawmakers are preparing to vote on changes that would give European residents far more control over their online privacy. 

In Britain, one of Facebook's largest international markets, local policymakers have highlighted how social networking sites have been used to target children for either sexual grooming or online bullying. 

About half of online child sexual exploitation now occurs on social networks, said Peter Davies, chief executive of the Child Exploitation and Online Protection Center, a British government body. 

"Facebook is a major one but not the only one," Davies told British politicians Tuesday. "The medium is not to blame, the medium might be managed better, so that it is safer for its users. What is to blame is human behavior." 

British lawmakers also are focusing on the online bullying of children after a series of prominent cases. 

Facebook has encountered controversy over its privacy policies in the past and is now facing additional scrutiny from the Federal Trade Commission, which is conducting an inquiry into other proposed changes to the company's privacy policies. Those policies would give Facebook automatic permission to take a user's post, including a post made by a teenager, and turn it into an advertisement broadcast to anyone who could have seen the original post. 

Privacy advocates have complained to the FTC that, with those proposals, Facebook was violating a 2011 order that required the company to obtain explicit permission from its customers before using their data in advertising. Facebook said it still had certain privacy safeguards in place for teenagers that make it harder for strangers to search and find them, but it declined to be more specific.

New discovery dubbed as ‘Li-Fi‘ to replace Wi-Fi in China?

Chinese scientists have successfully developed a new cheaper way of getting connected to internet by using signals sent through light bulbs instead of radio frequencies as in 'Wi-Fi', a move expected to radically change process of online connectivity. 

Four computers can be connected to internet through one- watt LED bulb using light as a carrier instead of traditional radio frequencies, as in Wi-Fi, said Chi Nan, an information technology professor with Shanghai's Fudan University. 

Under the new discovery dubbed as 'Li-Fi', a light bulb with embedded microchips can produce data rates as fast as 150 megabits per second, which is speedier than the average broadband connection in China, said Chi, who leads a Li-Fi research team including scientists from the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences. 

The term Li-Fi was coined by Harald Haas from the University of Edinburgh in the UK and refers to a type of visible light communication technology that delivers a networked, mobile, high-speed communication solution in a similar manner as Wi-Fi. 

With Li-Fi cost-effective as well as efficient, netizens should be excited to view 10 sample Li-Fi kits that will be on display at the China International Industry Fair that will kick off on November 5 in Shanghai. 

The current wireless signal transmission equipment is expensive and low in efficiency, Chi said. 

"As for cell phones, millions of base stations have been established around the world to strengthen the signal but most of the energy is consumed on their cooling systems," she said. 

"The energy utilisation rate is only 5 per cent," state-run Xinhua news agency quoted her as saying. 

Li-Fi was touted as a boon to China netizen community, the highest in the world with about 600 million connections. 

Compared with base stations, the number of light bulbs that can be used is practically limitless. 

Meanwhile, Chinese people are replacing the old-fashioned incandescent bulbs with LED light bulbs at a fast pace. 

"Wherever there is an LED light bulb, there is an Internet signal. Turn off the light and there is no signal," Chi said. 

However, there is still a long way to go to make Li-Fi a commercial success. 

"If the light is blocked, then the signal will be cut off," Chi said. 

More importantly, according to the scientist, the development of a series of key related pieces of technology, including light communication controls as well as microchip design and manufacturing, is still in an experimental period.

Ex-Nokia CEO Jorma Ollila says the former No. 1 mobile phone company made several mistakes at its peak, including failure to predict changing customers' needs.

In his autobiography, which translates from the Finnish as An Impossible Success, Ollila concedes that after 2001 the Finnish company was unable to sustain its role as the main innovator in the wireless industry. Several of its models flopped and it failed to sense popular trends such as folding clamshell handsets and touch screen models.

Ollila at the book publication that Nokia became "painfully aware" that its cellphone platforms lagged behind US software and the challenges posed by the iPhone.

He also described the planned sale of Nokia's smartphones and services to "arch rival" Microsoft as "dramatic and rave."

Youth thinks technology can be dehumanizing: Survey

Millennials are tech-savvy young adults who grew up with smartphones and iPads, but many think technology makes people less human, according to a poll. 

The survey of 12,000 people aged 18 and older in eight countries, commissioned by Intel, also showed that 18- to 24-year-olds want technology to be more personal and know their habits. Older women and those living in emerging markets are the most enthusiastic about the role technology can play in their lives, the findings showed. 

Dr Genevieve Bell, an anthropologist and research director at Intel Labs, said although the results of the survey that examined global attitudes towards technology innovation may indicate that young adults are rejecting technology, the findings could be more complicated. 

"A different way to read this might be that millennials want technology to do more for them," she said in a statement. 

Nearly 90% of young adults questioned in the poll admitted innovations in technology make life easier, but about 60% said people rely on it too much and that it can be dehumanizing. 

Seventy percent said technology enhances their personal relationships and about half believe it will have a good impact on education, transportation and healthcare. 

Women age 45 and older, and those living in emerging markets such as Brazil and India, are more enthusiastic about the impact technology could have on their lives. 

In China, more than 70% of women said technology is not used enough. 

"Women historically have become avid users of technology when that technology solves a problem, helps us organize our live and that of our families, as well as aids us in saving time and time shifting," Bell said. 

The findings showed that Italians and Japanese held the most negative attitudes toward technology. 

The survey, which was conducted in Brazil, China, France, India, Indonesia, Italy, Japan and the United States from July 28 to August 15, has a margin of error of plus or minus 0.89 percentage points.
