Big Data is THE biggest buzzwords around at the moment and I believe big data will change the world. Some say it will be even bigger than the Internet.

Without going into too much detail, we now have software like Hadoop and others which enable us to analyze large, messy and fast moving volumes of structured and unstructured data.

The FBI is combining data from social media, CCTV cameras, phone calls and texts to track down criminals and predict the next terrorist attack.
Facebook is using face recognition tools to compare the photos you have up-loaded with those of others to find potential friends of yours (see my post on how Facebook is exploiting your private information using big data tools).
Politicians are using social media analytics to determine where they have to campaign the hardest to win the next election.
Video analytics and sensor data of Baseball or Football games is used to improve performance of players and teams. For example, you can now buy a baseball with over 200 sensors in it that will give you detailed feedback on how to improve your

    Hadoop [8] is an open source implementation of MapReduce programming model which runs in a distributed environment. Hadoop consists of two core components namely Hadoop Distributed File System (HDFS) and the MapReduce programming with the job management framework. HDFS and MapReduce both follow the master-slave architecture. A Hadoop program (client) submits a job to the MapReduce framework through the jobtracker which is running on the master node.

    In today’s society, another revolutionary invention that has shaped the circulation of information is the World Wide Web, also known as the Internet. The Internet’s quality of data widely varies from either outright abominable to pristine and clear data. The widespread abundance of all of this data is now known as “Big Data” Silver (2012). Silver goes on to illustrate many examples of statistics at work among many fields such as the failure of the stock ratings agencies to properly rate the actual integrity and value of the corporations due to greed. Silver also goes on to criticize television pundits and classifies so called “analysts” and experts into two groups; hedgehogs and foxes.
