ichimunki (194887) writes "I am a mid-career software developer. I am from the Midwestern US and my native language is English. I've studied a few languages over the years, both human and computer... lately I've begun to wonder what is the best second (human) language for someone in this field to have. Or is there even any practical value in working to become fluent in a non-English language? I am not planning to travel or move/work abroad. But if I knew a second language would I be able to participate in a larger programming community worldwide? Would I be able to work with those folks in some useful capacity? Perhaps building products for foreign markets?"
