Shark-repellant rash guard makes you look unappetizing

The United States had 53 shark attacks in 2012, according to a University of Florida report. Many people find sharks both fearful and fascinating, but their presence in the water doesn't deter surfers and swimmers from jumping into the ocean waves.

Sometimes, people look like prey to sharks. One company is taking an unusual approach to preventing shark attacks with the creation of a shark-repellant rash guard. The form-fitting top does a lot of the usual rash guard things, like offer UV protection and wick moisture. What's different is the design on it.… Read more

Toshiba updates its laptop line for back-to-school

We're seeing plenty of new systems and updates to existing systems coming out of the Computex trade show, mostly tied into Intel's new fourth-generation Core i series processors.

That said, there are few surprises here. Some updated looks, more touch screens, a promise of upcoming Intel "Haswell" generation processors -- but as most of those new CPUs haven't been announced yet (with the exception of the higher-end quad-core models), don't expect new Intel processor model … Read more

How to update apps in iTunes 11

You may have noticed in Apple's recent iTunes update that they played a little game of "hide the app update button." Well, not to spoil the surprise, but we uncovered it.

Instead of its usual location across the bottom of the App pane in iTunes, you now have to select the new Updates tab located above the pane. Once selected, an Update All Apps button will appear in the previous location on the bottom.

Apple also decided to festoon any app in need of an update with a red Update ribbon. Logically, you might think that you … Read more

When watching a YouTube video in Firefox, you may want to switch to another tab in your Web browser to research something you just saw or heard, or maybe to a word processing application to take notes.

YouTube Smart Pause offers options to pause YouTube videos when … Read more

Use Google Drive on Android to save receipts

Make Sony NEX-7 videos more natural

I'm a big fan of Sony's Alpha NEX-7 and NEX-5n mirrorless cameras. They're practically more lens than camera, but both deliver exceptional image quality and advanced features for their small size.

For the past month I've been casually shooting photos and videos on the NEX-7 and scouring the Web for advice on getting the most from this camera. One tip that really changed the way I shoot video is Camera Dojo's advice on matching shutter speed with your camera's frame rate.

In the above video, I'll walk you through the steps to optimize … Read more
