GigsVT:
Something based on lines of code like COCOMO is probably not a good estimate for a kernel.
Kernel debugging is harder for one. Many of the drivers required some level of reverse engineering as well.
I’d say every “Kernel line of code” is probably worth 10 lines of code in userspace, if not more.

BadAnalogyGuy:
Why? Because you think there’s some fundamental difference between low level and high level code?
Papayas don’t need to be ripe to be useful. Green papayas can be pickled and be just as tasty as sweet ripe ones. The only differentiation is the time of picking.
Why would you give bonus points to the early pickers just because you don’t understand the pickling process?

Anonymous Coward:
What in the fuck are you talking about.

“One common way to address these inefficiencies is to rewrite the more complex parts of your PHP application directly in C++ as PHP Extensions. This largely transforms PHP into a glue language between your front end HTML and application logic in C++. From a technical perspective this works well, but drastically reduces the number of engineers who are able to work on your entire application. Learning C++ is only the first step to writing PHP Extensions, the second is understanding the Zend APIs. Given that our engineering team is relatively small — there are over one million users to every engineer — we can’t afford to make parts of our codebase less accessible than others.” —Haiping Zhao, proving my theory that web startups are not full of rock star programmers.
