Hadley Wickham is well-known for his prolific development of R packages. What motivates him? "Fundamentally learning about the world through data is really, really cool." This is an inspiring profile of someone who's had a huge impact on the world of data analysis and visualization. Highly recommended.
A new generation of companies is applying mathematical models to determine if you will pay back a loan or stay in a job. Do they judge you more fairly than people do?
Matching an infrared image of a face to its visible light counterpart is a hard, unsolved problem. Infrared emissions vary according to the temperature of the air and the temperature of the skin, which in turn depends on the person’s activity levels, whether the person has a fever, and so on. Here's a good overview of the problems and how a group of researchers in Germany is finding success.

Google's free translation app translates printed text via your phone's camera. Until recently, this trick required a connection to the Internet and translations occurred in Google data centers. With the latest release, however, translations occur directly on the device using a deep neural net within the app. It's amazing engineering and this post on the Google Research Blog offers a great overview of the challenges and how they made it work.
Awesome interactive visualization that demonstrates the basics of machine learning. This is a MUST PLAY-WITH article!
Nice tutorial by Jake Vanderplas that shows how to explore a dataset using unsupervised machine learning with Python. This is very well done and is easy to follow.
Dat is a data collaboration tool that simplifies the process of downloading datasets and enables users to fork, collaborate on, and publish new datasets. The goal is specifically to help users work with open government data and through collaboration, datasets will become cleaner, better annotated, and better understood along the way. This is an interesting project that's worth paying attention to.
