I know Python, Java, Javascript, PHP, MySQL, Actionscript3, HTML5 and Assembly though I rarely use them since my classes are mostly theory stuff or confine us to a single language. C++ right now.
I quite like how strict C++ is because the strictness leads to alot of possibilities in programming and more freedom in a sence.
Well I prefer to think of it as leaving you more free to do what you want. Most of the time it turns out that what I did was stupid though.
