“highway through the middle of a small town that anticipates growth? Who would want such a road through their town? It is a myth that we can get systems “right the first time.” Instead, we should implement only today’s stories, then refactor and expand the system to implement new stories tomorrow.”

“If we are diligent about building well-formed and robust systems, we should never let little, convenient idioms lead to modularity breakdown. The startup process of object construction and wiring is no exception.”

“The name of a variable, function, or class, should answer all the big questions. It should tell you why it exists, what it does, and how it is used. If a name requires a comment, then the name does not reveal its intent.”

“SPECIAL CASE PATTERN”
― Robert C. Martin, The Robert C. Martin Clean Code Collection (Collection)

“If you are not holding back some energy in reserve, if you don’t have a new plan, if you aren’t going to change your behavior, and if you are reasonably confident in your original estimate, then promising to try is fundamentally dishonest. You are lying. And you are probably doing it to save face and to avoid a confrontation.”

“We’ve all looked at the mess we’ve just made and then have chosen to leave it for another day. We’ve all felt the relief of seeing our messy program work and deciding that a working mess is better than nothing. We’ve all said we’d go back and clean it up later. Of course, in those days we didn’t know LeBlanc’s law: Later equals never.”
