The document discusses the OW2 programming contest in China, which is a joint programming contest between OW2 projects and Scilab. It has been held successfully in 2009 and 2010. OW2 projects propose topics for contestants to work on over the summer. Contestants then submit their work, which is evaluated by a jury. Winners are selected and awarded at a ceremony hosted by a Chinese university. The contest benefits OW2 projects, members, and the community by increasing collaboration with Chinese universities and students. It also benefits contestants by allowing them to contribute to open source projects and participate in an international event.
