I can get latched onto many subjects, most of them useless. Like, what is the best way to split firewood while living in an apartment building? Or what is the best RV for me (I'm not buying one until I spend X days renting)? It's really getting in the way of more worthwhile pursuits. 10 years ago I was quite engrossed in automatic layout of UI elements to automatically accommodate e.g. localized text of different size (Apple's iOS UI layout tools at the time were awfully crude, not sure about now). Around the same time I was much very into application state management (same problem solved by flux, but different approach). Having "solved" these two problems for my use case I have since moved on. Recently I am into mapping business workflows to data structures, visualizing them back, and then providing control over them, e.g. order/invoice/shipping processing in wholesale trade. Nifty stuff, and trickier than the other two things.
