KickJava.com: Java API By Example, From Geeks To Geeks. Holding a Program in One's Head. August 2007 A good programmer working intensively on his own code can hold it in his mind the way a mathematician holds a problem he's working on. Mathematicians don't answer questions by working them out on paper the way schoolchildren are taught to. They do more in their heads: they try to understand a problem space well enough that they can walk around it the way you can walk around the memory of the house you grew up in. At its best programming is the same. You hold the whole program in your head, and you can manipulate it at will. That's particularly valuable at the start of a project, because initially the most important thing is to be able to change what you're doing.
Not just to solve the problem in a different way, but to change the problem you're solving. Your code is your understanding of the problem you're exploring. It's not easy to get a program into your head. Even the best programmers don't always have the whole program they're working on loaded into their heads. 25 Best SSH Commands / Tricks.
