Our model “shows that closed-source projects are always slower to converge to a bug-free state than bazaar open-source projects,” say theoretical physicists Damien Challet and Yann Le Du. Oxford University researchers reveal surprising conclusions about closed- and open-source software projects in a new paper that may fan the flames in the divisive debate over how to make better software. In their study of a “microscopic model of software-bug dynamics” in cathedral, bazaar and closed-source software projects, theoretical physicists Damien Challet and Yann Le Du conclude, for the first time, that “software projects can converge to a bug-free state even with imperfect programmers.” The study is stirring excitement in the development community. “The model is a computer-science tour de force,” said computational neuroscience professor James L. Olds, who directs the Krasnow Institute for Advanced Study at George Mason University. Full Story
