A new report from the Coverity Scan project today indicates that a great many people do know what to look for, and open source software is at least on par if not better than proprietary software with respect to software defects. The Coverity Scan project evaluated selected open source projects and a number of anonymous proprietary codebases to identify “hard-to-spot, yet potentially crash-causing defects.” The results reinforce Linus’ Law.
According to Coverity, within the software industry as a whole a defect density of 1.0 is the average. As you can see from Coverity’s findings, the Linux 2.6 kernel, PHP 5.3, and PostgreSQL 9.1 all have signficantly smaller defect densities.
