How to Control Your Home with Your Cell Phone

By Glenn Derene, Popular Mechanics

Home automation is still evolving, and getting it to work requires knowledge of both household electrical wiring and computer networking. But once everything is hooked up correctly, it can change the way you interact with your home. We show you how you can use your smartphone as a remote control for your lights, heat and security in your home.

Home automation exists in the curious realm where screwdrivers and drywall meet PCs and routers. The cat­egory is still evolving — there are multiple, incompatible standards — and getting this stuff to work requires knowledge of both household electrical wiring and computer networking, but once everything is hooked up correctly, it can change the way you interact with your home.

Last month, I wrote about installing Insteon networked lighting in my home, which allowed me to link up switches and outlets throughout my house regardless of which branch circuit they were on.

The Insteon system works by sending data signals over radio frequency (RF) waves and your home’s power lines. As each device receives a signal, it rebroadcasts it, creating a mesh network that bounces commands instantly from one end of the house to the other. It’s an effective system for connecting lighting switches and loads without extra wiring, but it also forms the basis for a more sophisticated home automation network.

Meshed networks

Home automation is a broad and even somewhat vague concept. And plenty of companies sell systems that do everything from basic lighting control to full integration of home entertainment systems, motorized window blinds, climate control and home security. Many of these “whole home automation” systems from companies such as HAI and Crestron are geared toward the installer market and can cost many thousands of dollars. Other systems, such as SmartLabs’ Insteon and the competing Z-Wave system, tend to be more flexible and aimed at do-it-yourselfers.

Obviously, since I had already outfitted my house with Insteon’s lighting controls, it made sense to build upon that system. The first step was to integrate my networked lighting into my home’s data network. Insteon has a variety of different network interfaces, but I went with the $120 SmartLinc controller. The SmartLinc serves up its own Web page on your home network, allowing you to control your system from a browser window on any computer in the house, or via cell phones with Wi-Fi capability

People Search Engines: They Know Your Dark Secrets …

By JR Raphael, PC World

Social search engines can turn up your Amazon Wish List, photos of your kids, your musical tastes, and much, much more. What else is out there that you don't want everyone to know, and what can you do to protect yourself?

I know things about my lawyer I absolutely should not know. He's 55 years old, listens to the music of the band Creed, and screams like a little girl when riding roller coasters. He also relaxes with New Age spa treatments and is thinking about getting an electronic nose-hair trimmer. And that's just the start.

Now, let me be clear: I've never spent a single moment outside the office with this guy (and for what it's worth, I'd just as soon not be privy to his personal grooming habits). I learned all of these details by tracking his social footprint across the Web -- and he probably has no idea that he has left such a vivid trail behind.

In our age of social sharing, we expect some of our thoughts to be public. But as we slowly put more and more pieces of ourselves online, specialized search engines are making it easier than ever to pull them together into a highly detailed (and potentially invasive) profile of our virtual lives (read "Online Stalking Made Easy").

I'll let you in on a little secret: The picture isn't always pretty. And even if no rap sheet turns up, do you really want the world to know that you look at bad-breath cures online or post awful "Star Trek" fan fiction?

Just be aware of this beautiful tech ;P

Top 10 Useless Body Parts

10. Plica semilunaris
You may not know it, but you have a third eyelid. Pull open the two more noticeable eyelids and take a look -- it's located right in the corner by the tear duct. This small third eyelid is left over from what's known as a "nictitating membrane," which is still present in full form in some animals including chickens, lizards and sharks.

9. Body hair
No doubt we were once hairier. Up until about 3 million years ago, we were covered with body hair. But by the time Homo erectus arrived, the ability to sweat meant we could shed our woolly ways.

8. Sinuses
Doctors don't really know much about sinuses -- only that we have a lot of them. Possibilities for their function range from insulating our eyes to changing the pitch and tone of our voice.

7. Adenoids
Adenoids trap bacteria, but they're also prone to swelling and infection. Just ask any 7-year-old. Luckily, our adenoids shrink with age and are often removed, along with ...

6. Tonsils
Also prone to swelling and infection. If you still have them when you reach your 30s, it's almost an accomplishment.

5. Coccyx
More useful as a game-winning Scrabble word than as part of the anatomy, the coccyx, or tailbone, is made up of several fused vertebrae left over from the olden days when we had tails

4. Arrector pili
When we were hairier (see No. 9), the arrector pili made the hairs stand on end when we needed to appear bigger and scarier. Now, it just gives us goose bumps.

3. Wisdom teeth
Back in the day, when we ate mammoth meat off the bone and didn't floss afterward, our teeth tended to fall out. Therefore, when those reserve molars, aka "wisdom teeth," came in, they were welcomed. Nowadays, fluoride and dental plans have made them just a huge pain.

2. Appendix
Darwin claimed the appendix was useful for digestion during our early plant-eating years; it's dwindled down to little since we started eating more digestible foods.

1. Nipples on men Nipples appear on men because all embryos effectively start out as "female." The Y chromosome and testosterone are what make an embryo male. But nipples form before the testosterone comes into play, so the nipples remain.
