OSNews points in turn to a DevX article, Study: Linux Code Grows as Defects Decline. “Between December 2004 and July 2005, the “defect density” in the Linux kernel has fallen from 0.17 to 0.16 and all serious defects have been corrected, a new report out from code analysis firm Coverity asserts. Defect density declined by 2.2 percent.”
How many defects are in the OS kernel you’re using? Has the defect density gone up or down over time? Cars have satisfaction surveys. Consumer Reports lists pluses and minuses. Why don’t we have a similar test for operating systems.
