Tell me that you program in Java, and I believe you to be either serious or boring. In Ruby, and you are interested in building things quickly. In Clojure, and I think you are smart but wonder if you ship. In Python, and I trust you implicitly. In PHP, and we sigh together. In C++ or C, and I nod humbly. In C#, and I smile and assume we have nothing in common. In Fortran, and I ask to see your security clearance. These languages contain entire civilizations.
