A dark-themed terminal shows C code for a Linux USB driver, with a small inset image of a bespectacled developer on the right. The joke presents an extremely experienced kernel developer writing a USB driver from scratch in barebones vi, making ordinary programmers feel inadequate. It is used as a sarcastic reaction to impressive programming skill or to someone asking why a person has not accomplished an absurdly difficult task in a few hours.
