    According to the 2015 Forbes List released on Monday, Bill Gates' net worth rose to $79.2 billion (70.54 billion euros) from $76 billion a year earlier, putting the Microsoft founder at the top for the 16th year in the last 21.

    Mexico telecommunications mogul Carlos Slim Helu ranked second, at $77.1 billion, while Warren Buffett, chief of US investment firm Berkshire Hathaway, was third at $72.7 billion.

    Amancio Ortega, the Spanish founder of Inditex, which includes clothing retailer Zara, was fourth at $64.5 billion, while Oracle Chairman Larry Ellison was fifth at $54.3 billion.

    Forbes Magazine, which has compiled the list for 29 years, said it calculated each person's net worth based on stock prices and exchange rates on Feb. 13, 2014. It also noted that it had found a record 1,826 billionaires in the world last year. Among them were 290 newcomers, including 71 from China.

    Recently I had the opportunity to setup a multi-node hadoop cluster. The apache documentation is a little thin and I had to spend several hours trouble shooting issues and googling for help before I got it right.  The purpose of this tutorial is to save time for those setting up a hadoop cluster for the first time. If you are new to hadoop, you may read my tutorial on single node setup at Hadoop 2.x tutorial. If you have never setup hadoop before, it is a good idea to to do a single node setup the first time and then try the multi node setup.

    Hadoop is a framework (consisting of software libraries) which simplifies the processing of data sets distributed across clusters of servers. Two of the main components of Hadoop are HDFS and MapReduce.HDFS is the filesystem that is used by Hadoop to store all the data on. This file system spans across all the nodes that are being used by Hadoop. These nodes could be on a single VPS or they can be spread across a large number of virtual servers.MapReduce is the framework that orchestrates all of Hadoop's activities. It handles the assignment of work to different nodes in the cluster.

    Config files [Clicked : 3]
    When developing .NET applications, the importance of Web.config and App.config files is evident. They are used for many configuration purposes, such as specifying connection strings and web server settings.

    He may be one of the world’s pivotal computing pioneers, mentioned in the same exuberantly geeky breath as Steve Wozniak, Steve Jobs, and Tim Berners-Lee. His technological exploits may have earned him over $80 billion, making him the world’s richest man. Yet even Bill Gates is somewhat concerned about the potentially destructive power of technology.

    In a Reddit AMA (Ask Me Anything) on Wednesday afternoon, Microsoft’s former CEO fielded an array of questions ranging from the banal (“Do you have a pet?”) to the cringeworthy (“Star Trek or Star Wars?”) to the painfully esoteric.

    We evaluate 179 classifiers arising from 17 families (discriminant analysis, Bayesian, neural networks, support vector machines, decision trees, rule-based classifiers, boosting, bagging, stacking, random forests and other ensembles, generalized linear models, nearestneighbors, partial least squares and principal component regression, logistic and multinomial regression, multiple adaptive regression splines and other methods), implemented in Weka, R (with and without the caret package), C and Matlab, including all the relevant classifiers available today. We use 121 data sets, which represent the whole UCI data base (excluding the large-scale problems) and other own real problems, in order to achieve significant conclusions about the classifier behavior, not dependent on the data set collection.

    The classifiers most likely to be the bests are the random forest (RF) versions, the best of which (implemented in R and accessed via caret) achieves 94.1% of the maximum accuracy overcoming 90% in the 84.3% of the data sets. However, the difference is not statistically significant with the second best, the SVM with gaussian kernel implemented in C using LibSVM, which achieves 92.3% of the maximum accuracy. A few models are clearly better than the remaining ones: random forest, SVM with Gaussian and polynomial kernels, extreme learning machine with Gaussian kernel, C5.0 and avNNet (a committee
    of multi-layer perceptrons implemented in R with the caret package). 

    The random forest is clearly the best family of classifiers (3 out of 5 bests classifiers are RF), followed by SVM (4 classifiers in the top-10), neural networks and boosting ensembles (5 and 3 members in the top-20, respectively).
