C-Cramp (the C-Cramp College Radio Audio Management Program) is a Web-based frontend to MySQL for managing the types of things that small radio stations might need: audio files, data, and "metadata"; DJ and staff information, schedules, live music and program logs, and all sorts of other data. Currently, a cross-platform PHP application is the focus of the project, but more features and types of programs are planned that will hopefully enable easier playback, storage, loading, and entering for all types of applicable data.
DemoWave is a Web application for conducting referendums that allows anyone to propose a new referendum, minimizes the negative effects of people "spamming" the system with bogus referendums, and makes referendums where people disagree a lot take longer to go through. In addition, it can manage a set of laws and referendums on changes to those laws. DemoWave is intended for democratic organizations that need to decrease the bureaucratic load and increase the participation of their members in the decision-making process.
