This plus Founders At Work and as a side note - John Carmack's original .plan files. He goes into great details about issues he was having with Video cards(NVIdia vs. ATI), 3D rendering etc and then his plans of how he was going to tackle them, the approaches he tried, what did not work etc. I somehow find them very unvarnished and inspirational.
