I'd like to know how to get started to write a program for the GPU. Say I want to let the GPU calculate 4*2. I have an intel integrated HD4000 graphics card so I'd be better to use opencl I believe. I'm not really finding any tutorial on how to do this. Any help or comment is welcome.

I am a sophomore and I want to learn coding before I start college. I don't have much money and I need to know what resources I could use to learn a language. I have tried free online sites and apps but the abstract nature of the teaching and the lack of "real" coding makes me lose interest...

I've been wondering a while what are the reasons I should learn Java programming language. Thus far I've mainly seen someone saying how cool Java is and how it is this and that. But. I haven't found it 'cool', or to be honest, useful at all (and I could state that Fortran is cool...). Being...

I got chewed out today by one of my professor for not knowing or having an interest in coding. The professor told me it is a school that every math/science major should know. It does not have to be at the level of a computer science major, but competency is needed according to my professor...
