In 2008, April the 17th, I delivered this talk about Vagalume in the “VIII Jornadas de Software Libre de GPUL 2008“ conference in A Coruña (Spain), together with my mate Sergio, who talked about Modest. The talk just tried to give a brief and meaningful explanation about Vagalume, the Last.fm player developed by Alberto García (with some contributions for other developers, like me, from all around the world).
