Collabode: collaborative coding in the browser

Abstract

Collaborating programmers should use a development environment designed specifically for collaboration, not the same one designed for solo programmers with a few collaborative processes and tools tacked on. This paper describes Collabode, a web-based Java integrated development environment built to support close, synchronous collaboration between programmers. We discuss three collaboration models in which participants take on distinct roles: micro-outsourcing to combine small contributions from many assistants; test-driven pair programming for effective pairwise development; and a mobile instructor connected to the work of many students. In particular, we report very promising preliminary results using Collabode to support micro-outsourcing.
