There is a danger to open sourcing code that you won't be maintaining. Many employers now ask for your github account. If your coding habits change over the years, employers will look at your older, non-maintained work, and draw conclusions. Further, if you show a large number of abandoned projects, they may decide you "don't finish things."
Something similar bit me recently. I didn't have any of my TDD code samples available to send on short notice, so I sent an older project that, while it showed I could code, was not TDD, and not nearly up to my current abilities--I think it cost me the job. If that was what was in my github account, I may not even been asked for a recent sample. My recent work belongs to my employers, so that's a non-starter.
