A Conversation with Hadley Wickham

I become more and more interested and focused on R programming everyday and the main reason, without doubt, is the wonderful RStudio team with brilliant ideas making R a wonderful programming language for data scientists. I randomly ran into an interview with Hadley Wickham, who is mostly known with ggplot2 package, and I enjoyed reading every part of the interview. The interview briefly explains all the big changes happening in R that mainly all of them are originating from RStudio's wonedrful team.

Global Forest Watch: Big Data for Environmental Activism

In a great effort between several agencies worldwide, a new global data set is released entitled "Global Forest Watch". 

This dataset uses global satellite measurements (mainly from MODIS and Landsat projects) to map the losses and gains in the forest areas worldwide. The input data are from both visible and infrared sensors. The maps have a high resolution of 30 meter and are available from 2000 until present. The map is going to be updated every 16 days.

Data Sonification

Take a moment and enjoy "feeling" what climate data is trying to tell us. Scott St. George, a professor geography at the University of Minnesota says: "Data visualization are effective for some people, but they aren't the best way to reach everyone". Using global temperature data, the following video, called "A Song of Our Warming Planet", illustrates how average global temperature has risen in the past century and so.
