“All programmers are optimists”

“...give a great deal of attention to keeping his managers and his technical people as interchangeable as their talents allow. The barriers are sociological... To overcome this problem some laboratories, such as Bell Labs, abolish all job titles. Each professional employee is a "member of technical staff.”

“The programmer, like the poet, works only slightly removed from pure thought-stuff. He builds his castles in the air, from air, creating by exertion of the imagination. Few media of creation are so flexible, so easy to polish and rework, so readily capable of realizing grand conceptual structures.”

“Adding manpower to a late software project, makes it later.”

“As time passes, the system becomes less and less well-ordered. Sooner or later the fixing cease to gain any ground. Each forward step is matched by a backward one. Although in principle usable forever, the system has worn out as a base for progress. ...A brand-new, from-the-ground-up redesign is necessary.”

“Systems program building is an entropy-decreasing process, hence inherently metastable. Program maintenance is an entropy-increasing process, and even its most skillful execution only delays the subsidence of the system into unfixable obsolescence.”

“The management question, therefore, is not whether to build a pilot system and throw it away. You will do that. The only question is whether to plan in advance to build a throwaway, or to promise to deliver the throwaway to customers.”
