Let me explain "The Zone" to you then. "The Zone" is a programming
phenomena which occurs when you can literally see entire directories
of code in your head, all at once. It's a kind of nirvana that you
search for, mainly because code from this state is only very rarely
buggy or slow. I hypothesize that it's a result of the subconscious
brain depositing a finished product into the consciousness of the
individual. Aside from my crude explanations, let me make my point.
When in the zone, it's like stopping an oil tanker at sea. From the
time the skipper calls all stop and the engine room locks the screws,
it take about six miles or more for that boat to come to a full and
complete dead-in-the-water stop. Same thing for a programmer in the
zone. I have come out of the zone realizing I haven't eaten a meal
and it's time for the next meal.
Unfortunately, docs aren't part of the zone. Thus why the best and
most useful parts of applications have zero docs.

Yes, I agree there.

Most of my time is spent reading docs to best use existing APIs. Not
so much with APIs I'm familiar with, but for me to get really comfy
with an API it takes about 7,000 lines of real jewel code to get to
that level of comprehension. If you cut that code time in half again,
I'd never get anything done!

<quotable>That was stoopid of me</quotable>
My meter stick of program design is: if it needs a book, YOU DIDN'T DO IT RIGHT!

No, my memory isn't actually that bad for stuff I've written. I spend
most of that nostalgia time going "man, I was a complete and total
n00b three years ago, this could be done better..."

My general stance is that if you can't figure out what SourceScope
does, then I really can't help you at all. I agree, however, larger
programs (think GIMP in size) need to be documented. But the entire
UNIX philosophy is to build large systems using small blocks. Hence
manpages and all the command line functionality. Much of Linux is
command-line centric, and booting itself is a command-line activity.
You could technically type in the commands necessary to boot after you
had a working tty. It'd take for-freaking-ever, but it's possible.
Beats the heck out of Windows and it's dynamically linked libraries
with archives of undocumented functions you need to call. I should
share a Vista story, but I'll do it in another thread.
