Q Programming Languages - A New Use Case for Code Competition
Q is a domain specific language for time series embedded in the K programming language. It was developed to let them get the use of KDB with a much shorter learning curve. A code draws some of these veterans out of the woodwork and they start publishing Q solutions on GitHub, cubists slash study Q. The puzzles are relatively small and well understood. And it's a rare opportunity to see expert Q programmers at work on them.
