The coding period for this year Google Summer of Code has just started. I haven't blogged yet about Rhythmbox GSoCs, now is a good time to do it ;)
This year, 2 students will be hacking on Rhythmbox. Paul Bellamy (who I am be mentoring) started hacking on synchronization between Rhythmbox and media players.
And John Iacona (mentored by Jonathan Matthew) will spend the whole summer working on a contextual information pane for Rhythmbox. This information pane will display various information about the song being played (artist bio, similar artists, ...)
