Once again in 2010, OW2 and Scilab are organizing a joint open source programming contest. The purpose of the competition is to develop awareness for the OW2 code base among students and technicians, and to provide an opportunity for contestants to demonstrate their talent in computer programming. What's more, the contest aims at promoting teamwork and the ability of college students in science and technology to study and use OW2 open source projects. Based on principles of "freedom, sharing and creativity", and aiming at improving international communication and cooperation, the competition is overseen by IT professionals and academics from Europe and China. This year, as a unique complement to the programming contest, a corporate networking event is organized for sponsors and their guests with the theme: Open Source for Open Cloud.
