	abstract = {Large software compilations based on free, open source software (FOSS) packages are the basis for many software systems. When they are deployed in production, specific versions of the packages in the compilation are selected for installation. Over time, those versions become outdated with respect to the upstream software from which they are produced, and from the components available in the compilations as well. The fact that deployed components are outdated is not a problem in itself, but there is a price to pay for not being "as much updated as reasonable". This includes bug fixes and new features that could, at least potentially, be interesting for the deployed system. Therefore, a balance has to be maintained between "being up-to-date" and "keeping the good old working versions". This paper proposes a theoretical model (the "technical lag") for measuring how outdated a system is, with the aim of assisting in the decisions about upgrading in production. The paper explores several ways in which technical lag can be implemented, depending on requirements. As an illustration, it presents as well some specific cases in which the evolution of technical lag is computed.},

	abstract = {A significant number of Free Software projects has been widely used and considered successful. However, there is an even larger number of them that cannot overcome the initial steps towards building an active community of users and developers. In this study, we investigated whether there are relationships between source code metrics and attractiveness, i.e., the ability of a project to attract users and developers. To verify these relationships, we analyzed 6,773 Free Software projects from the SourceForge.net repository. The results indicated that attractiveness is indeed correlated to some source code metrics. This suggests that measurable attributes of the project source code somehow affect the decision to contribute to and adopt a Free Software. The findings described in this paper show that it is relevant for project leaders to monitor source code quality, particularly a few objective metrics, since these can have a positive influence in projects chances of forming a community of contributors and users around their software, enabling further enhancement in quality.},
