Associations, as the most usual form of non-profit organizations, are founded to achieve their goals, which may include the preservation and protection of human rights and freedoms, the protection of nature and the environment, humanitarian goals, social, educational, scientific and many other goals. In 2010, the DUMP association of young programmers was registered in the Register of Associations for the purpose of educating students about programming. Today, the association has several projects of its own, the most important of which are the Programming Basics School, DUMP Internship and DUMP Days. DUMP Days is their biggest project, a conference that includes various lectures and workshops sponsored by large companies from the information technology sector and in cooperation with the University of Split and the Faculty of Electrical Engineering, Mechanical Engineering and Naval Architecture, which is also the headquarters of the association.
