Author Danah Boyd on why teens and social media are 'complicated' (podcast)

When it comes to understanding how teens use social media, there's perhaps no one more clued in than Danah Boyd, except maybe teens themselves. An ethnographer with a Ph.D. in information from the University of California at Berkeley, she has spent the last eight years speaking with and observing teens from all walks of life.

Boyd's new book, "It's Complicated: The social lives of networked teens," is the culmination of this work where, as she writes, she attempts to "describe and explain the networked lives of teens to the people who worry about … Read more

Akamai CEO on streaming 4K TV into your home (podcast)

Just about every TV maker at the 2014 Consumer Electronics Show in Las Vegas was showing off 4K TVs. But to fully appreciate these Ultra High Definition (UHD) TVs, you'll need content that's recorded in 4K.

As far as I know, a 4K standard for broadcast, cable, and satellite isn't on the immediate horizon, nor is a standardized way to deliver the content via disc. So, the solution lies in Internet delivery. But that too raises a challenge because the amount of bandwidth required for 4K is considerably more than today's HD video.

Akamai, which has … Read more

Trip Hawkins' new game focuses on social emotional learning (podcast)

When Trip Hawkins left Apple to start Electronic Arts in 1982, he wanted to make the type of games that he and other young adult males liked to play. Thirty-one years and four children later, Hawkins interests have changed. He still wants to build games, but he's aiming them at young children in the hopes of helping them develop social and emotional skills.

In an interview (scroll down to listen), Hawkins said he learned about social emotional learning (SEL) from his own children. "I learned about it because almost two decades ago my oldest child stared attending on … Read more

Hour of Code campaign urges students to learn to code (podcast)

It's pretty unusual to see an issue supported by President Obama and House Republican Majority Leader Eric Cantor -- as well as Apple and Microsoft -- but they're all backing Hour of Code, which aims to get 5 million students in 33,000 classrooms around the world to learn at least one hour of computer science this week.

Sponsored by Code.org, the effort features entertainers Shakira, Ashton Kutcher, and Angela Bassett and athletes Chris Bosh, Warren Sapp, and Dwight Howard in videos supporting this cause. Tech luminaries including Bill Gates, Mark Zuckerberg, Google's Susan Wojcicki, and … Read more

Author behind 'Mean Girls' focuses on 'boy world' (podcast)

Rosalind Wiseman is known for writing "Queen Bees and Wannabes," a book about teenage girls that was the basis for the movie "Mean Girls." But now she's focused on boys. Her new book, "Masterminds and Wingman," is something of a user manual for parents of boys, with insight into how they think, how they interact with each other, and how technology -- including social networking and gaming -- helps shape their lives for better and worse.

Wiseman's new book is about boys and parenting, not technology. But it wouldn't be possible … Read more

Cyber Security Alliance chief: We're all connected (podcast)

October is National Cyber Security Awareness Month -- a time when the tech industry, government, businesses, and consumers focus on staying safe online.

I admit that there are lots of of days, weeks, and months on the calendar to recognize just about anything laudable, but October is as good a time as any to put some thought into how we can keep the Internet more secure. Whether it's government and large companies fending off major hack attacks from nation states or individuals protecting their devices against malicious software, we can all do something, starting with securing our own networks … Read more

Reduce the risk of TVs falling on children (podcast)

When we think of the "dangers" of TV and children, we're reminded of studies about kids watching too much TV or TV shows that encourage violence, overeating, or bad habits. And while there is some controversy about those issues, there is little doubt that TV becomes a real danger to kids if a set falls on them.

A study published in July by the American Academy of Pediatrics found that "more than 17,000 children are treated in U.S. emergency departments each year for a TV-related injury, equaling one child every 30 minutes."

Flat-screen … Read more

Study: 35% of new marriages started with online intro (podcast)

More than one-third of all U.S. marriages between 2005 and 2012 involve couples who met online, according to a study commissioned by dating service eHarmony.com.

The survey, conducted by Harris Interactive and analyzed by a University of Chicago professor, found that, compared to people who met offline, these marriages "were slightly less likely to result in a marital breakup (separation or divorce) and were associated with slightly higher marital satisfaction among those respondents who remained married."

The survey, based on a survey of 19,131 married respondents, was published last month in through the Proceedings of … Read more

Survey: Most teens take steps to protect their privacy (podcast)

A survey conducted by the Pew Research Center's Internet & American Life Project and Harvard's Berkman Center for Internet & Society has mostly good news about how teens approach privacy issues on social-networking services.

While "teens are sharing more information about themselves on social media sites than they did in the past," according to the study, "few teens embrace a fully public approach to social media," but "take an array of steps to restrict and prune their profiles." Here's the full report.

The study also found that:

Maker Faire CEO: Rockets and robots instead of pigs and pies (podcast)

Since 2006, San Francisco Bay Area maker movement aficionados have been making an annual pilgrimage to the San Mateo Event Center (the county fair grounds), to attend the Maker Faire. Self-described as "part science fair, part county fair, and part something entirely new," the Faire attracts a broad swath of attendees, not just in the Bay Area, but in other Maker Faires that are popping up around the world.

Last year 165,000 people attended the flagship events in the Bay Area and New York. There were also Maker Faires in Minneapolis, Detroit, and other cities around the … Read more
