In July, IEEE Spectrum released their fifth annual interactive ranking of the top programming languages.

Black swans are a metaphor for outlier events that are severe in impact (like the 2008 financial crash). In production systems, these are the incidents that trigger problems that you didn't know you had, cause major visible impact, and can't be fixed quickly and easily by a rollback or some other standard response from your on-call playbook. They are the events you tell new engineers about years after the fact.

One of the great modern battles of data science and machine learning is "Python vs. R." There is no doubt that both have gained enormous ground in recent years to become top programming languages for data science, predictive analytics, and machine learning. In fact, according to a recent IEEE article, Python overtook C++ as the top programming language and R firmly secured its spot in the top 10. read more
