Yami Nabe Revisited: How Much Duplicated Work is There in the (Android) Kernel? - Armijn Hemel, Tjaldur Software Governance Solutions

At LinuxCon Europe 2011 the LTSI team presented the results of the Yami Nabe research project, where they had studied how much kernels of several Android Gingerbread devices varied and in which areas device manufacturers should better cooperate. The algorithm that was used was quite coarse grained, but showed interesting results nonetheless. Professor Rainer Koschke (Universität Bremen) and I wanted to see if we could do better and get more fine grained results, by applying code clone detection techniques to the original results of the Yami Nabe project. The goal was to zoom in better on problematic areas to see if some of the differences detected by Yami Nabe actually were that significant. In this talk I want to present the methods that we used and the results of our research, explain what we will do in the future to get even better results and discuss how we could possibly turn our methods into a more useful tool for everybody.
