The inaugural Samsung Open-Source Conference opens Tuesday morning in Seoul, with keynotes from well-known figures in the open source world and a hackathon focused on Tizen, the company’s in-house mobile operating system. Samsung’s primary direct interest in the open-source world revolves around Tizen, a Linux-based mobile operating system that has functioned more as a bargaining chip in the OEM’s sometimes-fractious relationship with Google – which provides the Android OS used by almost all Samsung’s mobile devices – than as an operational mobile platform.
