A brief history and introduction to the XMPP protocol and its use for beginners with a background in programming but no protocol experience. If you are new to XMPP or want to better understand the other presentations in the XMPP track, this is the place to start! This talk will include an overview of the federation and routing model used by XMPP, specific protocol examples, coverage of the initial handshake and security model of XMPP, and common uses and extensions used by the XMPP community. It will provide background information that can be used by those new to the XMPP protocol to more fully understand the rest of the XMPP track.

The empty interface (interface{}) is one of the most interesting, powerful, and easily abused features of Go, but there are use cases for which it is uniquely and excellently suited. In this talk for the Go devroom, I will propose a set of rules which can be used to see if your use of interface{} will be the elegant and simple API that interface{} promised, or merely lead to a maintainability nightmare down the road.
