Going deeper with dplyr: New features in 0.3 and 0.4
This new tutorial covers the most useful new features in 0.3 and 0.4, as well as some advanced functionality from previous versions that I didn’t cover last time. (If you have not watched the previous tutorial, I recommend you do so first since it covers some dplyr basics that are not covered in this tutorial.)

New R Package – ipapi (IP/Domain Geolocation)
I noticed that the @rOpenSci folks had an interface to ip-api.com on their ToDo list so I whipped up a small R package to fill said gap.

How to factorize a 700 GB matrix with Apache Flink
This article is a follow-up post to the earlier published article about Computing recommendations at extreme scale with Apache Flink. We discuss how we implemented the alternating least squares (ALS) algorithm in Apache Flink, starting from a straightforward implementation of the algorithm, and moving to a blocked ALS implementation optimizing performance on the way. Similar observations have been made by others, and the final algorithm we arrive to is also the one implemented in Apache Spark’s MLlib. Furthermore, we describe the improvements contributed to Flink in the wake of implementing ALS.
