I have always been using Python for this but is about time to improve this skill by using more serious programming language. In sense that it should be lower lever and at least have static typing. Contenders are: C/C++/Java. My feeling is that Java knowledge would be more useful for future work but C/C++ would make more familiar with memory management.
