Node.js Interactive 2015

The ill-fated Google Wave, and the much more successful Google Docs, are both based on the concept of real-time collaborative document editing, and they both rely on an algorithm to seamlessly merge multiple changes to a single document called Operational Transformation, or "OT." Interest in live collaboration is growing in the Node community, given the ease of creating real-time applications with the evented programming model and packages like socket.io. But a lot of the information available about syncing strategies like OT is hard to understand or fraught with complex math. This talk will explain how to use OT in real applications in straightforward language, and also discuss other systems for coordinating data changes between clients.
