Garrett Eastman on 30 Jan 12Abstract: "The most popular Facebook games are being played by millions of users, sometimes only a few weeks after introduction. Although several of these games and their users have been studied, there currently exists no open-source version of such a game. In this thesis we present the design, implementation, and performance analysis of WebHack, a Facebook-integrated multiplayer game. WebHack is built upon the classic, but still popular, game of Nethack. We discuss the technical difficulties with file handles, process limits, communication networks, and handling failures. Further, we consider aspects specific to legacy applications, for example legal issues and technical limitations. We propose methods to circumvent these issues, and show a successful integration of the legacy game Nethack into our Facebookintegrated game system. We present the design of our system and evaluate the performance of the design in various scenarios. Among other results, we show that WebHack is a highperformance system, able to support over 300,000 concurrent players, handle arrival rates for up to 1,750 new players per second for over 60 seconds, and is able to recover within 10 seconds from a server failure."
