Seriously?! 500 million?!!!!!
That's the report that is coming out today...
Windows 2000 had 30 million lines
Vista had about 45 million lines
Windows 7 had an estimated 38 million lines (they slimmed down windows from vista a lot apparently)
the space shuttle ran on 400,000 lines of code
heck I write insurance processing software, and our entire system which even processes 834 XML records that healthcare.gov uses only has 1.1 million lines of code
Someone needs to teach these people code reusability and not write spaghetti code
