R programming, Data Analysis and Data Mining


For statistical data handling,  data analysis, data visualization R-programming is one of the best  programming language. R is Free and  Open source Software. Here is the license details of R.

  • It has nice GUI like r-studio and many more.

Nice package for data analysis with  r -programming is shiny.

Companies are looking for making more business by analyzing customer data. Data mining is one the growing research area which is used by many industries. R programming rank first as a data mining tool. Read more on this blog.



Nice Video on Linux

Must watch video.
Share it with your friends and students.
What the Tech Industry Has Learned from Linus Torvalds:

Sharing of knowledge is really a fun.

Sharing of knowledge is really a fun. When you share you should get fun, satisfaction in return.

Therefore from last 10 years I am conducting training programs for College teachers for LaTeX, the beautiful typesetting system.

Earlier people were attending such programs as per their own interest. It was really enjoyable experience.

In any workshop based on FOSS technology, I am trying that participants should become capable of 

  • Learn how to learn software on their own, that will help them to work on their research  or project
  • Try to find out errors on their own, that way they will learn to help themselves
  • Try to understand what is going on and why? No spoon feeding
  • Help other participants, so that they will learn more and will understand the benefit of sharing knowledge.
  • Related important websites
  • Mailing lists

How ever, day by day it is becoming difficult to conduct course on LaTeX.

In Maharashtra, India, there is lot of requirements coming from various places. How ever, they want to attend the course so that either they get certificate or credit of the workshop in terms of marks.

70% participants are due to that.

So quality of participants is very poor. No one want to try on their own. There are no interesting questions from the participants.

They do not want to give try, or don’t want to discuss among other participants. It is very frustrating. 😦

They don’t want to learn how to learn on their own.
Here are points I observed:

  • If local organizer is keen on the better participation, the workshop becomes enjoyable
  • If management of other technical resources planned carefully, workshop takes better form

Local organizer requires true wish to take care of these things.
Recently I have 2 good workshops. One of which was in Abeda Inamdar college, Pune and other was in Bhopal, RGPV.

Anyways, I came to conclusion that if I want to share knowledge, I should write some document, book and make it available for my satisfaction.

FOSS entered in Pune School

In the first week of the school, we got a pleasant surprise. School started using Linux in their computer lab. Not only that, the teacher told students about the word FOSS, Linux Kernel.

Teachers got training from IIT Bombay in this vacations. The school is going to use Computer Masti research product of IITB.
Computer Masti is meant for teaching computers to children. Book on Computer Masti: Lessons and Activities in this book are based on free and open source software – the Ubuntu Linux distribution.

In the last academic year, my daughter was working with preparation of presentation as a part of her school project work. She took my pen drive to store her work. After using the pen drive in the one pc at the school she was not able to open it on the other pc in the school again since, it is all the time showing virus on it. Her other school met when used their affected pen drives at house. Their home pcs affected with virus. Only our home pc was safe since there is Mandriva Linux. Her friends came to know about it.

They all started wishing that school should have Linux to avoid virus problem. And their wish turns into the reality. 🙂

When school teacher went to IIT Bombay for training of Computer Masti.. They met a past student of the school in IITB. Teacher obviously asked her, which operating system you used Linux or XXX? She said Linux.

Teacher asked: In the school you learnt other system XXX, how difficult you find to work on Linux after that?
Student said: No problem while working with Linux. On the other hand the student said : we hate the other system XXX.
