Open source distributions such as Gentoo need to accurately track dependency relations between software packages in order to install working systems. To do this, Gentoo has a carefully authored database containing those relations. In this paper, we extract the Gentoo package dependency graph and its changes over time. The final dependency graph spans 15(More)
In this paper we make the case that software dependencies are a form of innovation adoption. We then test this on the time-evolution of the Gentoo package dependency graph. We find that the Bass model of innovation diffusion fits the growth of the number of packages depending on a given library. Interestingly, we also find that low-level packages have a(More)
International research collaboration is a growing social phenomenon (Wagner and Leydesdorff 2006; NSF-NSB 2008). It results in part as a strategy to deal with increasingly complex problems and raising costs of research (Luukkonen, Persson; et al. 1992; Gibbons, Limoges et al. 1994; Adams, Black et al. 2005). It also responds to government policies oriented(More)
