Although I read the latter, I had never read the former. Really good stuff.
P.S. Is there some pdf plugin that won’t use up 100% of my CPU? Reading PDFs is noisy on my laptop
in Optimization: Your worst enemy
Why doesn’t efficiency matter when you’re updating menus or controls? Look at the human factors. A mouse is held approximately 2 feet from the ear. Sound travels at approximately 1100 ft/sec. This means that it takes approximately 2ms for the sound of the mouse click or keystroke to reach the ear. The neural path from the fingertip to the brain of an adult is approximately 3 feet. Propagation of nerve impulses is approximately 300 ft/sec, meaning the sensation of the mouse click or keystroke takes approximately 10ms to reach the brain. Perceptual delay in the brain can add between 50 and 250ms more.Now, how many Pentium instructions can you execute in 2ms, 10ms, or 100ms? In 2ms, on a 500MHz machine that’s 1,000,000 clock cycles, so you can execute a lot of instructions in that time. Even on a now-clunky 120MHz Pentium there is no noticeable delay in handling the controls.
