I am a software development team leader. I prefer to use whatever language works best but those langues tend to be Java, C/C++ & Bash. I work on biggish embedded systems. Those systems have always had microprocessors with a 32-bit (or larger) registers. I am very interested in ancient languages like Lisp & Erlang for future work as I try to rise to the top of the abstraction tree. I want to focus less on the how and more on the what.
