Michal is a sailor and every sailor should keep a log. We also like Twin Peaks and absolutely love the Log Lady.
The log is "white" because it's like a blank page, and like Gandalf the White, and also because we believe that taking white pills is a great way to exist in the world:
White pill 1: being aware of a difficult situation or position and having a fighting "can do" attitude and not giving up, plus accomplishing said thing(s) within the difficult situation 2: being optimistic, not merely through gut feelings but via having thought about a situation enough to understand how to get through it successfully – Source: Urban Dictionary
We sort of put these together and – POOF! – The White Log appeared.
