Well, yes, but programming, and singing are not primarily physical, muscle memory, things. Both require a lot of conscious thought, and carry a temptation at times to do what's needed to "get by." Maybe that's where the "programming as combat" metaphor begins to break down.
in reply to Re^2: Programming is combat
in thread Programming is combat
There are times when it's absolutely appropriate to "get by"-- sometimes writers, to use another example, will combat writer's block by writing something they know isn't good, with the intention of changing it later. But in general, it's important to remember that you perform what you rehearse-- and it's a good idea to take the time to get the notes really solid before you go out on the stage. Or to apply it back to programming, habits of thought affect how you approach new problems, what it occurs to you to try to make things happen-- and that's a case where having practiced good programming practices can really save your behind.
Obviously, I've been doing too much reading lately in my self-improvement quest. I'll add your book to my list if you finish it though, if only to show good monastic solidarity (probably won't buy it, but I'll encourage my local library to. Sorry, no independent wealth here. That vow of poverty really stinks sometimes.)
