There are many science podcasts, but very few dedicated to computer sciences. Created in 2010 by researchers and students at Edinburgh University, Compucast is a lively and varied podcast about computer science and related technologies. Presented in a magazine format and aimed at an audience with a reasonable grounding in the subject, the programmes cover subjects such as robotics, systems biology, semantics, artificial intelligence and energy efficient data centres, amongst others. The podcasts are in MP3 format and are free to download.
