Apple (like many giant, multinational corporations) has been avoiding paying the taxes they owe to the country by setting up foreign "subsidiaries" in tax-haven countries, and moving jobs out of the country. Now they want a special tax break to reward them for doing that.

NASA was recently named one of most engaged brands on Twitter. I recently caught up with NASA's Social Media Manager John Yembrick and Deputy Social Media Manager Jason Townsend to find out what exactly they are doing to engage their audience.

I can honestly -- and naively -- say that it never once occurred to me that I couldn't grow up to be anything I wanted. It wasn't until I started my current role that I realized that a woman who was encouraged to pursue STEM as a child can be a rare thing indeed.

Last month, in a waiting room at Lucile Packard Children's Hospital in Palo Alto, Calif., a small boy sat with a laptop, engrossed in a game. The game he played is Re-Mission 2: Nanobot's Revenge, one of a new collection of free online games for young cancer patients.

These laws have formed the basis of a modern-day witch-hunt that thrives on the vagaries of the Internet and too often captures individuals who make relatively simple errors online, rather than those who produce such material or directly abuse children.

It's the second day at Google I/O 2013 in San Francisco. While the other members of the HuffPost tech team on site have been pursuing sessions on Android and Google Glass, I've been focused on something much more mundane: the World Wide Web.

Essentially, NoFap is a reaction by young males to the fact that some of them -- thanks mostly to omnipresent digital porn -- are losing interest in finding and engaging real-world sex partners.

It's easy to argue that the best teacher could teach with nothing but a chalkboard and a piece of chalk, but we're not all Michelle Pfeiffer. And, considering our country revolves around computers, it's nearly impossible to prepare teachers and students for the future without access to technology.

Here Carlos Slim spoke candidly with Fernandez about the digital future, how he thinks technology is shaping society today, why philanthropy is the key to a happy life, and what he likes most about L.A.

The drama plays out of whether or not Kenyatta and Ruto will appear in the Hague. The balance between repudiating colonialism and protecting human rights is infinitely tricky. We must get it right.

It's just the kind of thinking, where video is about surveillance, that we get confused notions of why having classroom cameras can make a difference for teachers. First, let's get clear on why these aren't "surveillance" cameras in either the literal or figurative sense.

Data for data's sake is powerless. It's only when end users are given access to the data to gain insights, see trends and make predictions that the data can actually tell a story. In this way, data becomes a bridge to knowledge.

There's a new urgency in Washington, a sense that the time has come to establish a national media shield that would protect news organizations and reporters from federal subpoenas and secret spying. It won't happen, certainly not in any meaningful way.
