The legendary hacker who refused to optimize
The Story of Mel is a classic piece of hacker lore about Mel Kaye, an early programmer who wrote machine code for a drum memory computer. Mel eschewed compilers and assemblers, writing raw binary. He famously programmed instructions so they would physically align with the rotating drum's read head at the exact millisecond they were needed. When a coworker tried to fix Mel's seemingly erratic code, the program broke; Mel's hacks were perfectly timed masterpieces.
