Yoga for Geeks

I have been doing Yoga for the past two weeks and the results are great. Here I reproduce some of these ancient Indian exercises which can hopefully help you. Note- yoga is thousands of years old and there is no copyright !

Learning and Teaching R #rstats

a brief ppt I made for the New Delhi Meetup Group http://www.meetup.com/New-Delhi-R-UseR-Group/

The inevitable weaponization of the weather

 

Reasons I think weaponization of the weather (or climate) is inevitable

1) The weather is an inter connected system with many zero sum scenarios to nation states. This includes sharing of water resources and moving manufacturing in offshore locations

2) As climate change effects gradually cause increase variance in climate, this will lead to added hardship for populations. The economics branch of mechanism design might be better suited to simulate what a few degrees more or less in temperature will lead to riots, happier populations, economic stimuli just as agricultural studies focus on rainfall prediction, crop prediction etc.

3) Nation states have always had weaponry on a game theory basis. The weather being an interconnected system can be both dampened and enhanced in it’s adverse variance by man made means, and the interconnectedness can ensure deniability . Example a man made out of time El Nino effect can hamper rainfall in Indian monsoons and bring change in politics in that democracy

I still hope nations do not weaponize the weather. Unfortunately I am quite sure some of them are already thinking of both predictive and defensive mechanisms for countering climate change without any thought of how this affects other countries.

A lot of my earlier writings on weaponization of weather have been marked more by conceptual theories, added tit bits and a wee bit of creativity. I apologize for the immature lack of scholarly rigor in earlier writings as I work alone to refine my skills. )

 

Decision Making in the era of Big Data, Cloud Computing, Data Science and R

a talk I gave at IIT Delhi at Department of Management Studies to doctoral students is uploaded here

India and R #rstats

While India is downloading a lot of R packages, it seems only one Indian (?) has ever gone to a UseR annual conference- the latest being in LA http://user2014.stat.ucla.edu/#registration despite India having a huge hub of analytics talent. (and even impressive number of official SAS certifications)

But seriously just one attendee. With so many downloads and so many R Blogger visits?

The lovely cartograms from the brilliant Rapporter team here

You need to hover to get the data by country

You can see the app here and http://rapporter.net/custom/R-activity/#CRAN_all/6

Clearly this is not true as many people of Indian origin do contribute to the R program, however the country wide demographics suggest that the R project is clearly a Western (and not a truly global endeavour) . Maybe the R foundation can try moving the conference a bit more Eastern (hemisphere wise)- or maybe the digital divide is just a practical way of the world order.

Unless China creates a fork of R ;)

 

Talking on Analytics

I will be talking to doctoral and MBA students at IIT Delhi on May 10. The talk is Data Analytics and Cloud Computing and will be there for 2 hours, but will be much more broad ranging than that including touching on HR Analytics and Data Science. If you are local to Delhi around this date- you can contact me in case you want to attend in person.

AN INTRODUCTION TO BIG DATA ANALYTICS AND CLOUD COMPUTING
In this talk we will discuss big data analytics including Hadoop and R, and the emergence of Cloud Computing. The focus will be on introducing fast changing technologies and what it means for enterprises and researchers.  We will also cover data science as potential career paths.

Movie Review – Two States (Bollywood 2014)

As a Punjabi engineer turned IIM MBA, who turns into a writer after marrying a woman from a different state (that’s me here!) , I was a bit apprehensive on how good or bad this movie could be. It was a relief and indeed a joy to watch this movie. The comic timing is light and everyone acts well. Watch Two States as the feel good movie of New BollyWood 2014. Alia Bhatt is lovely, Arjun Kapoor decides to move his acting and facial muscles, and the veteran team of actors fits in the roles very very naturally. A good way to spend a few hours, and be amazed at the amazing diversity of India.
