#2 monolithic kernel aka "hybrid" kernel⁷

#3 estimate based on total SLOC²⁸ + dependent on driver selection, X not included

#4 estimate based on total SLOC which is sourced from Gary McGraw "Building Secure Software - How to avoid security problems the right way"²⁸ i.e. dependent on driver selection, GDI/GDI+ included

#5 0.016% defect density 2005 survey, 2004 survey, + guess 0.004% increase 2006 update Linux bugs increasing = 0.02%

#6¹⁰ based on estimate¹⁶ 63,000 in W2K Software Quality: Why Windows 2000 has 63,000 \"bugs\" and Linux* does not

#7 roughly - depends on options kernel, Microkernel

#8 estimate, based on newsgroup discussions and Microkernel with a lower bound of 3.9M lines from Windows Embedded CE 6.0 kernel Special Report: Windows CE 6 arrives with 100% kernel source, and upper bound of estimated 50M lines for all of Vista
