I'm not sure if it counts as charity but my first job out of school was managing data for non-profit bat research project. There was a small amount of scripting and some website work. Not too much intensive programming though. I also did some similar work for a conservation organization that runs out of a local park. That one was volunteer work. Local conservation or biology groups like that typically have a lot of data but not many people with the skills to organize and analyze it. They're usually pretty grateful to people that can help with that.
