Why surge pricing scheme of Railways in premium trains is a visionary idea?

From today, India Railway is going to apply Flexi Pricing Scheme (As I understand it is Surge Pricing Scheme actually.) in premium trains like Rajdhani, Dooranto and Shatabdi. As usual Indian Public and Opposition leaders are shouting, crying here and there. But they don't understand its a very visionary scheme that will provide long-term advantage. Believe me.

Railway want you should not travel more. Its not healthy.15 day leaves that you take to go your home town once in a year will be saved if you don't travel.When you don't take leave, will remain in office.

KK: It all began with this girl who came to interview me. In those days I used to live alone. So she said: You must be very lonely. I said: No, let me introduce you to some of my friends. So I took her to the garden and introduced her to some of the friendlier trees. Janardhan; Raghunandan; Gangadhar; Jagannath; Buddhuram; Jhatpatajhatpatpat. I said they were my closest friends in this cruel world. She went and wrote this bizarre piece, saying that I spent long evenings with my arms entwined around them. What’s wrong with that, you tell me? What’s wrong making friends with trees? PN: Nothing. KK: Then, there was this interior decorator-a su…

R – your tool for data analysis

R‬ is a language and environment for Statistical Computing and Graphics. R provides a free/open source, cross­-platform, object-oriented environment to perform data analysis and visualisation tasks. Strength of R lies in its vibrant community, robust package repository and strong graphics capabilities. ‪ R provides all necessary tools required for various stages of a data analysis project. It provides techniques for data acquisition and processing as well as for data analysis and visualisation. It ranges from accessing data in various formats (CSV, XML…) to all possible ways of data manipulation (tabulation, aggregation…)to rich support for graphics (histogram, box plot etc.) to statistical models (regression, ANOVA…). It is not always necessary to use built-in and supported functions and packages. Depending on the requirements, one can also develop his/her own functions, scripts and packages. Recently, CDAC Mumbai has announced a 3-day course on R entitled “Using R for D…
