The fundamental problem with program maintenance is that fixing a defect has a substantial chance of introducing another.
Interpretation
Program maintenance is challenging because fixing one problem can lead to new issues.
This quote by Fred Brooks highlights the inherent difficulties in software maintenance, where attempts to resolve existing defects may inadvertently create new ones. It underscores the complexity of systems where changes can have unforeseen consequences, emphasizing the need for cautious and well-considered approaches in programming and software development.
In practice
In a team meeting discussing software updates, I could use this quote to emphasize the risks of changes.
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

Third, how do we keep America safe and lead the world without becoming its policeman?
I believe quite simply that the small company of the future will be as much a research organization as it is a manufacturing company.
It is interesting to come across people who feel that a ghost communicating via a spell-checker is less far-fetched than a software glitch.
I never felt that the naming issue was all that important, but I was obviously wrong, judging by how many people felt. I tell people to call it just plain Linux and nothing more.
Measuring programming progress by lines of code is like measuring aircraft building progress by weight.
