450 Million Lines of Code Can't Be Wrong: How Open Source Stacks Up

An anonymous reader writes "A new report details the analysis of more than 450 million lines of software through the Coverity Scan service, which began as the largest public-private sector research project focused on open source software integrity, and was initiated between Coverity and the U.S. Department of Homeland Security in 2006. Code quality for open source software continues to mirror that of proprietary software — and both continue to surpass the industry standard for software quality. Defect density (defects per 1,000 lines of software code) is a commonly used measurement for software quality. The analysis found an average defect density of .69 for open source software projects, and an average defect density of .68 for proprietary code."

Re:Defects fixed for proprietary may differ.

Propietary defects are ones that may cause financial harm. FOSS defects are ones that cause annoyance.

I know that our code has more defects than we'd consider fixing purely because the CBA isn't there.

I'm guessing you mean defects in propietary software only gets fixed if they have an impact on the bottom line? Otherwise that whole reply makes no sense.

Anyways, that is not much different from the OSS model. Whoever cares about the sub-system that has a bug, fixes it, and if nobody cares (or has the skills to fix it) it can go ignored for years. The selector for OSS is different, but the end result is the same: nobody gives a fuck about the end user unless it directly affects their day/paycheck/e-peen.

What else is in the "industry"?

and both [proprietary and open-source software] continue to surpass the industry standard for software quality

... What else is there? And why is this unknown third type of code dragging down the "industry"?
