At the Rensselaer Center for Open Source Software students develop open source software solutions to solve societal problems.
For example, at the HFOSS Symposium today I talked to Graylin Kim who is working on the New York Senate Open Legislation Service where people can look up any bill that is being discussed in the New York Senate, get a permanent url to share and discuss on their own websites or grab all the data via REST. The idea is to encourage more citizens to get involved in legislature. Developers can get involved at http://nysenate.gov/developers or #nyss_openlegislation @ Freenode.net for OpenLegislation
You can check out the RPI Center for Open Source and the other projects students are working on. The program was started by a grant from an RPI alum, Sean O’ Sullivan. He started MapInfo (now PBInsight) and JumpStart International (article).
They were at the HFOSS Symposium sharing how their program worked with other educators.
