Watch Out For Geotagging

Nope, it's not a new form of graffiti, or wall art, or vandalism, or whatever it's called in your neck of the woods. If you have a smart phone, or perhaps a video or digital camera that has built-in GPS capability, then most likely all the images you take with the smart phone camera contain a geotag, which provides the lat/long of where you were when the photo was recorded. smart photo
That could be good and useful for the photographer, but it can also be useful for the bad guys. The concern to law enforcement and many others is that the casual (and probably frequent) user may not realize the location information is embedded in the image. This could compromise your privacy and safety when such images are posted online, or even forwarded. You never know who's looking at your stuff once it leaves your control.
For most smart phone users, this feature can likely be turned off, but as is the case in our social-networking obsessed society, is probably on by default.
And turning off this feature may disable other GPS applications, like mapping.
So, decide whether you want this info in all your images and videos, get out that instruction manual, and make the choice., a website created by security consultants, provides instructions for disabling geotagging for some popular smart phones.

White Space

The FCC has recently approved the use of "white space" for advanced broadband applications.
This white space is frequency spectrum between broadcast TV channels. There are still some issues to work out, like potential interference to wireless microphones and similar signaling devices. The advantage is that this swath of spectrum will be available for free, require no licensing, and will have longer range and be able to penetrate through walls, delivering Internet speeds ranging from 15 to 20 megabits per second over a range of several miles (your mileage may vary). Imagine, Wi-Fi on steroids! Products using this newer technology are expected to be showcased within the year.
