According to Coverity we hit a major milestone today. Elementary now has a defect rate of ZERO. 0. NADA. That's something to be proud of. We still have to improve EFL and Enlightenment (EFL is at 0.52 and Enlightenment at 0.66). The average for "good quality commercial code" is 1.0, so we're doing well either way, but we can do better. Take Elementary as a lead.
And yes. Static analysis tools do not catch everything, and they often produce false positives too, but it's like having another set of eyes automatically review your code all the time pointing out potential issues, and that can only help improve the quality.
