I am starting to take an intrest in computer programming. I am having trouble on deciding where to focus on. I am intrested in graphic development, OS design, things of that nature. I self taught myself through my A+ cert. So before I spend money on college classes, I was wondering if someone could piont me in a direction to learn more about the subject. The differences in C++, HTML, Java, etc. Just basic information would be helpful. Maybe a helpfull website if you know one.
