I'm working at a software consultancy that a has a lot of volunteers available for about a month and a half at a time (when we're between projects and learning things) and we'd like to start contributing to open source projects that have a positive social impact. Any idea which projects we can look at?
The constraints are:
Built on a fairly modern language and stack that's suitable for beginners but has wide adoption - Java+Spring+Hibernate / RoR / Groovy+Grails - basically a stack we'd expect to work on in other projects too.
Has / aims to have a positive on peoples lives - like Ushahidi, OpenMRS, RapidFTR, FrontlineSMS, etc.
Has well defined stories and requirements, or has owners who are willing to work with our analysts to come up with them.
