Not a programmer - an Astrophysics student instead.
However, I like programming both for fun and for use on my course. I have some knowledge of:
C++
Java
HTML/CSS
PHP
Fortran 95
Python
Scilab
I don't know any of them well, except for maybe HTML/CSS and Scilab but even then only well for a rank amateur. I can write simple programs in all of them but good programs in none of them (yet!).
