New rules: How to unlock your smartphone

Until recently, if you wanted to unlock your phone in order to switch carriers, there was a good chance that you'd have to do it without the cooperation of the carrier you were with.

HoloLens: Look who's innovating

Poor, slow-footed old Microsoft. It just can't adapt to changing times or keep up with more innovative, agile and forward-looking companies like Apple and Google. That's been the way many of us have thought of Microsoft for a long time. But it may be our thinking that's old and outdated.

What Gamergate says about the tech industry

For the last two months the video-game industry has been embroiled in an ugly outbreak of name-calling and worse. This dustup, called <a href="http://www.computerworld.com/article/2840556/the-charge-of-the-troll-brigade-what-to-know-about-gamergate.html">Gamergate</a>, was named after a hashtag on Twitter, where much of the nasty fight has taken place. It's a battle in which women have been threatened with violence and even death by hardcore gamers.

Drones are the new Pets.com

Everyone, from Amazon to Google to Martha Stewart, has been lauding the benefits we'll all reap by the use of drones, and there's a gold rush on to cash in on the technology.
