You find him sitting in the corner, headphones on. There’s an empty cup of coffee next to him. He is typing feverishly but every now and then he pauses, puts on an empty expression, followed by a twinkle in his eye before he gets back to typing. The screen has an eerie green glow. The cursor seems to be jumping around, doing things without him even touching the mouse or arrow keys. One moment he is typing, creating functions, and another moment he is deleting multiple lines at once. He types some ancient looking string and magic seems to happen. You watch in wonder, amazed by the speed and dexterity. You wonder if he is human. You think twice before interrupting him, not because you are always so courteous but because you have forgotten what you wanted to ask. And then he gets up, a satisfied expression on his face. You blurt out, ‘How in the world did you do all of that?’ He smiles and simply says, ‘Vim’.
