Home networking Part 7: Power line connections explained

Editors' note: This post is part of an ongoing series. For the other parts, check out the related stories section below.

Power line networking basically turns a building's existing electrical wiring -- the wires that carry electricity to different outlets in the house -- into network cables, meaning they also carry data signals for a computer network. And this means virtually all households, in the U.S at least, are "wired for" power line networking. It doesn't replace a regular network, so you'll still need a router, but it's a good way to extend … Read more

Get Automatic Lifelogging with Saga for Android

Meet Saga, the "Automatic Lifelogging" app. This is the app you've never known you needed. Remember what you were doing last Thursday? Saga remembers. OK, I guess that sounds a bit creepy. But really, here's what the app does...

Get custom-tailored audio with Adapt Sound on the Galaxy S4

If glasses are adjusted for varying eyesights, why isn't the same logic applied to our ears? Today, most music players (that's probably your phone) are designed with a one-size-fits-all standard -- the manufacturer adjusts the audio tone and left/right balance to what might suit most people.

It turns out, however, there are differences in our hearing, including unique nuances in balance and processing.

Some phones do let you dig into accessibility settings to adjust left/right balance, but the Galaxy S4 might be the first phone that actually adjusts the audio output to your needs automatically.

While other apps may request permission to access your photos, music or connect to BBM.

Denying an app permission to one of the requested categories is a good way to protect your personal data, but should you mistakenly deny an app permission, you'll need to know where to go to edit these … Read more

How to mirror your Galaxy S4's screen on your TV

Despite the ever-increasing screen size on Samsung's Galaxy line, some types of media beg for a sit-back, big-screen experience. It could be a YouTube video, or just a little something you shot (and even edited!) on your phone. And, as more developers support this option, mirroring can even enable you to play games on your TV while your phone acts as a controller.

The S4 offers a few ways to mirror your phone's screen (not just media) onto your TV, so that whatever you see on your phone is what appears on the TV.
