The quality and security levels of open source code are continuing to improve, according to the latest annual audit by code analysis tools vendor Coverity.
The third edition of the Coverity Scan Open Source report measured a 16 per cent reduction in static analysis defect density over the past three years among the projects subjected to scrutiny, including Firefox, Linux, PHP, Ruby and Samba. The report covers analysis of more than 11 billion lines of code from 280 open source projects.

Beween 2006 and 2009, more than 11,200 defects in open source programs have been fixed thanks to Coverity - 2, 700 of those in the last year.
