Ask HN: Am I too old to start a programming career?

I first got into coding ~5 years ago. Taught myself a few languages, did some online contract work on the cheap. I decided to go back to school for a CS degree. By the time I graduate, I'll be in my early 30's.

I know that the CS field tends to skew young, especially for entry-level work. Am I likely to face significant barriers due to my age?
