Normal Sudoku rules apply.
Killer Cages: Digits in a cage may not repeat and must sum to the given total.
Kropki Dots: Digits separated by a white dot must be consecutive. Digits separated by a black dot must have a ratio of 2:1 (i.e. one must be double the other).
Solution code: Row 6, left to right. (9 digits, no spaces.)

F = 15 hex, that much I know

Nailed it! "\x" indicates a hex byte in the C programming language. I generally work in web tech, not C, so this was almost "#0F" to be more in my wheelhouse. But the "\x" notation seemed quirkier, so it won out.

Very clever application of all the ways to make 15!
