Open and Closed Source Kernels Go Head to Head

Earlier today I presented at the 30th International Conference on Software Engineering a research paper comparing the code quality of Linux, Windows (its research kernel distribution), OpenSolaris, and FreeBSD. For the comparison I parsed multiple configurations of these systems (more than ten million lines), and stored the results in four databases, where I could run SQL queries on them. This amounted to 8GB of data, 160 million records. (Iíve made the databases and the SQL queries available online.) The areas I examined were file organization, code structure, code style, preprocessing, and data organization. To my surprise there was no clear winner or looser, but there were interesting differences in specific areas.
