In this tutorial, you put Ruby to the test by constructing a chat server application that can serve a large and scalable number of clients. By the end of this tutorial, you will know how to use the standard Sockets class to build both client and server applications, as well as how to use classes that simplify sockets programming, including TCPSocket and TCPServer.
