BitLocker - Password Protect USB Drives

Do you often leave your USB drive lying around?  Worried about unauthorized access to the device?  The latest versions of Windows offer something called BitLocker to defend against this threat.

Not only does it password protect your USB drive, but it encrypts the data just in case someone hacks into it.  By password protection, you'll need to enter your password to unlock the drive each time you want to connect it to a computer. 

In Windows 7 or Vista, simply right click your drive and select BitLocker.  Then follow the steps to set up a password and be prepared to wait a bit for the installation to finish.  Take a break and let the process finish.

The only downsides however are the limitations.  BitLocker only allows recent Windows operating systems to access your drive - such as Windows 7 and Vista.  Macs, PS3s, Linux, and other systems won't recognize the drive.

Another flaw is the fact that people often leave USB drives connected to systems they walk away from.  It doesn't automatically disconnect your device after a certain idle time, leaving it 100% vulnerable to unauthorized access if left unlocked. 

Still, it's a step ahead when it comes to data security and you can be reassured if your BitLocker defended drive falls into the wrong hands.  It's safe to say a good 98% of the people who get ahold of your unplugged USB drive will not be able to break through BitLocker.

4D Plenoptic Cameras Revolutionizing Photography

Ever take a photo only to later discover something went wrong with the focus and/or exposure?  Ever hate the difficulty of taking pictures in dark or extremely bright scenes?  What about images with too many things to focus on and not enough time to capture the multiple focus levels?

This can all be solved with a plenoptic camera. A revolutionary new camera technology that essentially captures a full range of lighting and focus levels (or a 4D light field) for adjustment later.  Not only do these devices save the trouble of getting the right focus and exposure on the spot but they will reduce the time needed for setting up equipment and leave more time for actual shooting.

So which cameras use plenoptic technology? This Lytro Light Field Camera is the latest buzz of the news right now.  It captures 4D light information with an array of micro-lenses that capture 11 million rays (or 11 megarays) of light at once. In terms of the image quality, these 11 megarays produce professional 22 megapixel images in addition to the 4D light field capturing. You can view a large gallery of the plenoptic captures (or "living pictures") to see just an example of this camera's raw photography power.  I'm betting we'll also have plenoptic video cameras soon enough to revolutionize the film industry as well - reducing the number of retakes needed due to focus and/or lighting.
