Recently we had a question on the public mailing list for Revolution R Open (RRO), on the topic of "MKL multithreaded library and mclapply do not play well together".

If you're not familiar with these topics, here is a quick primer:

Imagine taking one person's body and face, and then being able to make them speak using someone else's voice -- and their mouth movements and facial expressions, too. That's now possible to do in real time, thanks to a research team at Stanford, using only a consumer-grade PC and what appears to be a Kinect depth-of-field camera:

 

Thanks to Dr George Esaw, I recently learned that Ross Ihaka, co-creator of R, was featured in a full-page advertisement placed in The Economist by the University of Auckland back in April:

The dplyr package is a popular toolkit for data transformation and manipulation. Over the last year and a half, dplyr has become a hot topic in the R community, for the way in which it streamlines and simplifies many common data manipulation tasks.

I'm honoured to be giving the opening keynote at the Effective Applications of R Conference (EARL) Conference in Boston on November 2. My presentation will be on the business economics and opportunity of open source data science, with a focus on applications that are now possible given the convergence of big data platforms, cloud technology, and data science software (especially R) charged by the contributions of the open source community.
