The project is filling with legacy code insensibly. Only five years ago it was nice clean code, but now there is nobody who could understand it completely or predict what would involve its changing. Just as thermodynamic entropy is always increasing in the universe, so too code entropy is on the rise. Is it possible to stop its growth? Is it possible to prevent? Or should we just throw away the injured component and start from the very beginning? Let’s talk about some common practices.
