Ask HN: How have you used your [tech] skills to improve your local community?

I'm looking for ways to put my talent/skills to good use, and the most obvious route for that (short of switching companies and joining a non-profit) that I can think of is to get involved/"give back" in my local community. I'd love to hear if anyone in the HN community has anecdotes or ideas from which I might draw inspiration.
