We have recently discovered that the brain benefits from a broad variety of problem-solving activities such as crossword puzzles and Sudoku. There also appear to be benefits when we mix these activities up: doing crosswords puzzles for a while and then switching over to Sudoku, and later, back again.

This challenge, viz. the confrontation with the programming task, is so unique that this nove...
