And even though I only have my GED I am still very familiar with how computers work, memory management, building virtual machines, etc. I have a small scheme here that compiles to rubinius bytecode and then gets JIT'd by LLVM into machine code that I will release one of these days and I have read tons of papers and feel like I know as much or more then your average CS degree grad.
Everything you need to know is on the internet nowadays. All you have to do is spend the time to reach out and grab it and you can learn anything you want to learn and eventually get any job you want to get if you only apply yourself hard enough.
I did not mean to disparage college degrees, merely to make a comment that you can learn as much or more then you would learn at your average CS degree school by just applying yourself and reading online, then practice, practice, practice.
