I love small and simple, I love self-contained. But then I got to GetMimeType, where he wrote his own binary search code instead of calling the C library to do it.

Though it sounds simple, binary search is a minefield of edge cases and I've seen textbooks that do it wrong.

So when I read the GetMimeType function, I didn't think "how nice and simple"...I thought "Hmm, I bet that doesn't work."

Those 11 lines of reimplemented bsearch are correct.

Oh, I'm sure they are, purely based on who wrote them...but in any ordinary codebase I'd toss this code out in a second and replace it with a library call. It's just not worth the effort to decide whether it's correct -- like not bothering to bend over to pick up a lost penny.
