Is Linus' Law real?
Last week Coverity released a report showing that open source software has a lower defect rate than proprietary software. This of course has some folks claiming that Linus' Law works!
Now I'm about as big of a fan of open source as they come, but I'm not sure if this is the proper course for cause and effect. I've done a lot of thinking about Linus' Law in the past few months as part of the Red Hat Product Security Team. What the Coverity report shows is that open source has fewer of the kind of defects Coverity can detect. That's really it.
On the topic of open source code quality and bugs though, I think there are a few more important things to consider.
