Have you ever wondered what computer programmers actually do? Well now you can watch people code in an activity called "live coding." Wikipedia states that live coding "is a programming practice centred upon the use of improvised interactive programming. Live coding is often used to create sound and image based digital media, and is particularly prevalent in computer music, combining algorithmic composition with improvisation. Typically, the process of writing is made visible by projecting the computer screen in the audience space, with ways of visualising the code an area of active research. There are also approaches to human live coding in improvised dance. Live coding techniques are also employed outside of performance, such as in producing sound for film or audio/visual work for interactive art installations." There is also now a live coding video streaming website (Livecoding.tv) where you can watch people code online.
