Once considered a radical upstart, open source has moved from disruption to default. Its methods and culture commoditized the technologies that drove the Internet revolution, and transformed the practice of software development. Collaborative and transparent, open source has become modus operandi, powering the next wave of innovation in cloud, data, and mobile technologies. OSCON is where all of the pieces come together: developers, innovators, businesspeople, and investors. In the early days, this trailblazing O'Reilly event was focused on changing mainstream business thinking and practices; today OSCON is about how the close partnership between business and the open source community is building the future. That future is everywhere you look. Now in its 15th year, OSCON is the best place on the planet to prepare for what comes next, from learning new skills to understanding how new and emerging open source technologies are going to impact how we live, work, and do business. In keeping with its O'Reilly heritage, OSCON is a unique gathering of all things open source, where participants find inspiration, confront new challenges, share their expertise, renew bonds to community, make significant connections, and find ways to give back to the open source movement. The event has also become one of the most important venues to unveil ground-breaking open source projects and products.
