ZikO, if you know C++, then knowing one scripting language is useful, it can be Ruby, Python (or even Lua, etc). Note that learning a language isn't a binary thing, so I suggest you to use a week to learn Python and use it try to solve some of your practical problems. After a week you will be able to tell if it's useful for you.
