Hey, so I'm in college right now and have a major completely unrelated to computers; but they have been a hobby of mine for-like ever. Most of my friends are engineering majors and have all learned the basics of a few languages. For the most part they all started with fortran which seemed pretty sweet but not really powerful. I was wondering if there are any languages I should look into learning and where I would find out more about them. I began reading this book from the MIT library and it was using LISP as it's primary language; but it was started in the 1950's and seems really outdated. I'm not sure what kind of programming is out there or even what type I really want to get into. What is a good language to learn for hobby things, like making programs on my computer, and how do I even go about writing a program. It's not like a window pops up on my screen and says, "write program here".
Sorry for being vague, I just don't really know where to start atm. Anything and everything helps.
