Deduplication in Windows 8

Data deduplication is a technique to reduce storage needs by eliminating redundant data in your backup environment. Only one copy of the data is retained on storage media, and redundant data is replaced with a pointer to the unique data copy.
The goal is to store more data in less space by segmenting files into small variable-sized chunks (32–128 KB), identifying duplicate chunks, and maintaining a single copy of each chunk. Redundant copies of the chunk are replaced by a reference to the single copy. The chunks are compressed and then organized into special container files in the System Volume Information folder.

Use Mobile as a Webcam

Oooops!! I don’t have a webcam in my Laptop, I am working in the office where I can’t take webcam every day, Oh No!! My Webcam broke today.. For all these issues there is better way, use your mobile as webcam and save few bucks... Yes you can use your mobile as a Webcam.(Most of the new mobile comes with built-in camera and supports JAVA), if you don’t have one, get one ;-)

You can turn your iPhone, BlackBerry, Windows Mobile or Symbian smartphone into a high-quality wireless webcam. Connect it to a Mac (iPhone version only) or PC using a Wi-Fi connection and share bright moments of your life that cannot be caught with a built-in webcam or USB camera.
