Last internship : I learned modern opengl, libav and ffmpeg. I even was the only dev on some big contracts. Was a fucking cool internship because I learned everything I wanted to. But my manager had really low social skills. So been able to teach myself all of that was a good thing for everybody, but not for him. When the internship was over I got the worst mark of my promotion for the business with for comment that I didn't enough ask for help Oo wtf dude. Still get the best final markof the promotion and the only one who didn't work on web technologies :p but fuck you should have tell me sooner man...
