* Introduction

On Tuesday night Rob Pike and Andrew Gerrand each presented at the [[http://www.sydney-gtug.org/][Sydney Google Technology User Group]].

Rob's talk, "[[http://www.youtube.com/watch?v=HxaD_trXwRE][Lexical Scanning in Go]]", discusses the design of  a particularly interesting and idiomatic piece of Go code, the lexer component of the new [[https://golang.org/pkg/exp/template/][template package.]]

The slides are [[http://cuddle.googlecode.com/hg/talk/lex.html][available here]]. The new template package is available as [[https://golang.org/pkg/exp/template/][exp/template]] in Go release r59. In a future release it will replace the old template package.

Andrew's talk, "[[http://www.youtube.com/watch?v=HQtLRqqB-Kk][Cuddle: an App Engine Demo]]", describes the construction of a simple real-time chat application that uses App Engine's [[http://code.google.com/appengine/docs/go/datastore/overview.html][Datastore]], [[http://code.google.com/appengine/docs/go/channel/overview.html][Channel]], and [[http://code.google.com/appengine/docs/go/datastore/memcache.html][Memcache]] APIs. It also includes a question and answer session that covers [[http://code.google.com/appengine/docs/go/gettingstarted/][Go for App Engine]] and Go more generally.
