What do you guys think I should learn next? I've been studying javascript/ruby and I would like to diversify what I can make. I don't want to rush learning new languages, but it's interesting to learn about paradigms that certain languages enforce. What's important to me(not in order): 1) Being an omni-platform developer 2) I only know two high-level languages, so learning a low level language will benefit me. 3) I want to get into Natural Language Processing and deep neural networks/AI, machine learning etc. 4) I'm a self-taught programmer, so the amount of good resources online/amazon is a big factor. 5) I need a fucking job. 6) I like making web applications/web games, and I would like to make native applications/games as well.
