The department shelled out $1.24 million to Stanford University, Coverity and Symantec to hunt for bugs in open-source software.
The LAMP collection of projects includes Linux, Apache Web server, MySQL database and PHP, Perl or Python.
Apparently the analysts found that there was a lower collection of bugs per thousand lines of code than a baseline of 32 open-source projects analysed. It is not clear if this is a pat on the back for LAMP projects, or a statement of how bad the other Open Source Projects were.
Standard Open Source projects had 0.434 bugs per 1,000 lines of code while the LAMP stack had an average of 0.29 defects per 1,000 lines of code.
PHP was the most buggie part of the LAMP stack and was much higher than the rest. Of course they did not test a stack of Microsoft products.
