	abstract = {Summary. In general it is assumed that a software product evolves within the authoring company or group of developers that develop the project. However, in some cases different groups of developers make the software evolve in different directions, a situation which is commonly known as a fork. In the case of free software, although forking is a practice that is considered as a last resort, it is inherent to the four freedoms. This paper tries to shed some light on the practice of forking. Therefore, we have identified significant forks, several hundreds in total, and have studied them in depth. Among the issues that have been analyzed for each fork is the date when the forking occurred, the reason of the fork, and the outcome of the fork, i.e., if the original or the forking project are still developed. Our investigation shows, among other results, that forks occur in every software domain, that they have become more frequent in recent years, and that very few forks merge with the original project.},

	abstract = {This paper describes a peer-production movement, the hackerspace movement, its members and values. The emergence of hackerspaces, fablabs and makerspaces is changing how hacker communities and other like-minded communities function. Thus, an understanding of the nature of hackerspaces helps in detailing the features of contemporary peer-production. Building on previous work on {\textquoteright}fabbing{\textquoteright}, two different sets of results are presented: (1) empirical observations from a longitudinal study of hackerspace participants; and (2) a theoretical description of hacker generations as a larger context in which peer-production can be located. With regard to (1), research data has been collected through prolonged observation of hackerspace communities and two surveys.},

	abstract = {This paper examines the factors that influence the long-term sustainability of FLOSS projects. A model of project sustainability based on organizational ecology is developed and tested empirically. Data about activity and contribution patterns over the course of five years for 2,772 projects registered with SourceForge is analyzed. Our results suggest that the size of the project{\textquoteright}s development base, project age and the size of niche occupied by the project are positively related to the project{\textquoteright}s ability to attract user and/or developer resources. The ability to attract resources is an indicator of the perceived project legitimacy, which in turn is a strong predictor of the project{\textquoteright}s future sustainability. Thus a project{\textquoteright}s ability to attract developer and user resources is shown to play a mediating role between the demographic (size and age) and ecological (niche) characteristics of the project and its future sustainability. Our results support the applicability of tenets of organizational ecology related to the liability of smallness, the liability of newness, and population characteristics (niche size) to the FLOSS development environment. The implications of the results for future research and practice are discussed.},
