Big Data

Google 's algorithm called MapReduce and how it was used  with Hadoop

So what's 'Big Data'.it is a collection of large datasets that cannot be processed using traditional computing techniques. Big data is not merely a data, rather it has become a complete subject, which involves various tools, techniques and frameworks.


  • Using the information kept in the social network like Facebook, the marketing agencies are learning about the response for their campaigns, promotions, and other advertising mediums.
  • Using the information in the social media like preferences and product perception of their consumers, product companies and retail organizations are planning their production.
  • Using the data regarding the previous medical history of patients, hospitals are providing better and quick service.


Big data is really critical to our life and its emerging as one of the most important technologies in modern world.The amount of data produced by us from the beginning of time till 2003 was 5 billion gigabytes. If you pile up the data in the form of disks it may fill an entire football field. The same amount was created in every two days in 2011, and in every ten minutes in 2013. This rate is still growing enormously.


Hadoop runs applications using the MapReduce algorithm, where the data is processed in parallel on different CPU nodes. In short, Hadoop framework is capable enough to develop applications capable of running on clusters of computers and they could perform complete statistical analysis for a huge amounts of data.

The possibility of quantum computing breaking encryption algorithms

The possibility of breaking encryption algorithms is a powerful motivating factor for many countries of the world. Thus, knowledge of the enemy's encryption systems could give a huge advantage in intelligence, while at the same time contributing to the conduct of new fundamental research in the field of physics, since modern experimental systems have at their disposal only less than 100 qubits.    To achieve the useful computing performance of a supercomputer, we probably need machines with hundreds of thousands of qubits. In order for the devices to function correctly, they must correct all minor random errors in the software. In a quantum computer, such errors arise due to imperfect elements of the circuit and the interaction of qubits with their environment. For these reasons, qubits can lose coherence in literally a split second. A quantum computer with 100 qubits can simultaneously represent 2100 solutions. For some tasks, this exponential parallelism can be used to create a h

Simple steps to protect your privacy.

  Step 1. Download DuckDuckGo on all your devices With just one download you'll get tracker blocking, private searching, increased encrypting, and privacy grading on all of your browsing. Our mobile app for iOS/Android (DuckDuckGo Privacy Browser) and browser extensions for Firefox, Chrome, and Safari (DuckDuckGo Privacy Essentials) has all of this in one seamless package. Privacy, simplified. Step 2. Update your software Your device operating systems get out-of-date over time, and old software can contain security bugs or settings that leak personal data. Set your devices (and the apps on them) them to update automatically. That way you'll always have the latest, safest versions. Step 3. Update your privacy settings Make sure your devices are using the best privacy settings. Here are step-by-step instructions for all the major device types. Especially make sure you adjust per-app location settings, so that your location history isn’t leaking where it shouldn’t. For extra bonus
