I've noticed that, beyond a certain point, the term "program" is not actually very useful. Because it's open on the other window, is Facebook a program? Is the news feed a program? The buddy list? The chat features? The photo upload? The status update? How about the API? Is that a program? I could easily say that my scripts are programs. They're rarely more than a file large. But "program" is not a descriptive term for them; I say "script" because that explains that they are not services. They run once, do their job, and finish. Or something. At work, I have a domain focus. There are swaths of code I own, and other swaths that my domain has strong and weak connections to. I know my domain. I can boot it up in my head at will, though it's too large to stick: I have to walk through each room independently, rather than having some manifold presence in every room. And there are a ton of things that I have to look up every time, because I don't actively work on those pieces. But there's no clear division at which I can say, "This is the program. I should put it all in my head." We just remember everything that we can, and try to remember where to find out everything that we can't. I think that's reasonable.
