Which database does Facebook & Google use ?

Facebook has moved to a NoSQL database named HBase. Google uses their own system called BigTable. What is NoSQL ?

    Click Extract (3) to begin extraction. This may take a few minutes to complete.


    Once extraction is complete, open the folder Tor Browser from the location in which you extracted the bundle.
    Double click on the Start Tor Browser (4) application (it may be called Start Tor Browser.exe on some systems.)

    The "VIDALIA" window will shortly appear.


    Once Tor is ready, Firefox will automatically be opened. Only web pages visited through the included Firefox browser will be sent via Tor. Other web browsers such as Internet Explorer are not affected. Make sure that it says "Tor Enabled" (5) in the bottom right corner before using it. To reduce the risk of confusion, don't run Firefox while using the Tor Browser Bundle, and close existing Firefox windows before starting.

    Just go to the "TOR" settings and enter the address of the proxy server given to you by your your institute admin.
