The hallway hums with old fluorescent lights, a soft electric whisper in the quiet hours of a California night. In a half basement at Sun Microsystems, a man in a plaid shirt leans over a terminal as if listening for footsteps in the code. James Gosling is not a mystic, but at this hour he treats the compiler like an oracle, asking questions in curly braces and waiting for prophecy. Outside his office stands an oak tree, ordinary bark and leaves, yet to the people in this lab it feels like a witness. The human brain craves patterns, says the psychologists; it injects meaning into accident and calls it destiny. If destiny wears sneakers and drinks stale coffee, it looked a lot like the Green Team in the early nineteen nineties.
