Fixing a fifteen-year-old curve fit bug

> There’s something magical about diving into solving a bug. I’m able to find real focus, time flies and I come out the other end tired yet invigorated. I really enjoy these kinds of bug-hunting puzzles and I seem to be fairly good at it.1 But maybe I’m just overly stubborn (in a good way!).

This is a really eloquent way of describing the feeling. I feel like most people have the instinctive response to ask "why do you care?"

Honestly, not clear! Sometimes it's just satisfying to leave stuff better than you found it. Fixing a bug is therapeutic like cleaning your house, only it's more intellectually interesting :)
