> These days, I think the pendulum has swung too far from thinking about the program, maybe mapping it out a bit on paper before writing code. Sometimes I think about code structure like a sudoku where you have to eliminate two possibilities by following through what would happen. Writing the code is (to me) like placing the provisional numbers and finding where you have a conflict. I simply cannot do it by holding state in my head (ie without making marks on the paper). It could definitely be a limitation of me rather than generally true.
