Crowdsourced videos, photos could aid Boston blast investigations

Law enforcement officials could have something very different on their hands as they investigate the dual bomb blasts that struck the Boston Marathon finish line today: a potential abundance of photo and video evidence from the public.

Government surveillance, while growing, still misses more than it catches. But events with thousands of spectators offer the potential for a detailed crowdsourced record of what happened.

This public panopticon is changing how we see the world. February's Russian meteor was captured by many dash-cams mounted in Russian cars, but in this case the event is of profound interest to law enforcement … Read more

Roku shutting down VideoBuzz channel for streaming YouTube on the sly

One of the biggest shortcomings of the otherwise excellent Roku 3 is its lack of an official YouTube channel, although savvy users can get around that limitation with a variety of workarounds, including the "private" VideoBuzz channel. Or at least used to be able to.

Since I first got glasses in the fourth grade, I dreamed about them having some sort of built-in head-up display, feeding me real-time data about the world around me. Two seconds into the Google Glass launch video, and I said, out loud, "SHUT UP AND TAKE MY MONEY."

Turns out, Epson has been working on similar "iGlasses." Like Google Glass, these are an early entry into the technology. So if you're hoping for a snarky review about early tech, you'll be disappointed.

If you want to know what it's like having something like this, what it can and will be, and a shocking lack of jokes about me wanting Geordi La Forge's barrette thing, read on.… Read more

What is the blockiness in my TV's picture?

A common complaint I get via e-mail or in comments on other articles involves a picture that breaks up into what look like little blocks.

Often, people incorrectly refer to these as "pixels," or blame their TV settings.

In fact, this artifact is in the source, and unfortunately, there's not much you can do about it.… Read more

LED LCD backlights explained
