	abstract = {Organizational culture has been recognized as an influential factor affecting the successes and failures of usability work in organizations; however, there is a lack of research on organizational culture in open source software (OSS) development. This paper shows that there are different kinds of cultures in OSS development projects and builds propositions on the relationship between culture and usability work in OSS development projects. Partly those are derived from the literature, partly from an exploratory empirical inquiry. We speculate whether there is an ideal culture type for usability work in OSS development or whether usability work should be modified to fit the different cultures of OSS development projects.

	abstract = {Free and open source software is characterized by the freedoms and criteria that are warranted by specific licenses. These licenses describe the rights and duties of the licensors and licensees. However, a licensing change may be necessary in the life of an open source project to meet legal developments or to allow the implementation of new business models. This paper examines the motivations and impacts of license changes in open source projects. After a state of the art on the subject, a set of case studies where projects changed their license is presented. Then a set of motivations to change licenses, the ways to legally make this change, the problems caused by this change and a set of benefits of the license change are discussed.

	abstract = {With the increasing prominence of open collaboration as found in free/libre/open source software projects and other joint production communities, potential participants need to acquire skills. How these skills are learned has received little research attention. This article presents a large-scale survey (5,309 valid responses) in which users and developers of the beta release of a popular file download application were asked which learning styles were used to acquire technical and social skills. We find that the extent to which a person acquired the relevant skills through informal methods tends to be higher if the person is a free/libre/open source code contributor, while being a professional software developer does not have this effect. Additionally, younger participants proved more likely to make use of formal methods of learning. These insights will help individuals, commercial companies, educational institutions, governments and open collaborative projects decide how they promote learning.

	abstract = {This paper describes problems that arose with the scaling and internationalization of the open source project Catrobat. The problems we faced were the lack of a centralized user management, insufficient scaling of our communication channels, and the necessity to adapt agile development techniques to remote collaboration. To solve the problems we decided to use a mix of open source tools (Git, IRC, LDAP) and commercial solutions (Jira, Confluence, GitHub) because we believe that this mix best fits our needs. Other projects can benefit from the lessons we learned during the reorganization of our knowledge base and communication tools, as infrastructure changes can be very labor-intensive and time-consuming.},
