This is utter nonsense. My libc implementation is 26038 lines of code,
and I have not spent 2603.8 days on it. The project was started in
December and I've hardly worked every day/round the clock on it.

For something like VP62, leaving out the step of discovering how it
works and just assuming you already have specs, I would think 3000
lines of code would take at most a week or two for a competent coder.

This is bullshit you were taught in a CS class, and has nothing to do
with the real world.
