Another essay by Paul Graham, interesting as always:
Holding a Program in One's Head (http://www.paulgraham.com/head.html)
QuoteYour code is your understanding of the problem you're exploring. So it's only when you have your code in your head that you really understand the problem.
Bye!
... and your understanding of the problem is not necessary the solution of the problem ...
;D
Actually, I can't keep it all in my head. In my case, it is more like a locker room full of closed lockers, where you can only have one or two lockers open at once. You have to keep trying to remember where bits and pieces are kept, and figuring out how to get this piece here connected to that piece there, and shuffling the lockers around so as to somehow tidy up what is becoming a real nightmare of a mess.
In fact, you either wish you had never started, wonder whether you can just push on through, or debate if starting over would be the best way to go at this point.
