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

| The slides are [available here](http://cuddle.googlecode.com/hg/talk/lex.html). |
| The new template package is available as [exp/template](https://golang.org/pkg/exp/template/) in Go release r59. |
| In a future release it will replace the old template package. |
| |
| Andrew's talk, "[Cuddle: an App Engine Demo](http://www.youtube.com/watch?v=HQtLRqqB-Kk)", |
| describes the construction of a simple real-time chat application that uses |
| App Engine's [Datastore](http://code.google.com/appengine/docs/go/datastore/overview.html), |
| [Channel](http://code.google.com/appengine/docs/go/channel/overview.html), |
| and [Memcache](http://code.google.com/appengine/docs/go/datastore/memcache.html) APIs. |
| It also includes a question and answer session that covers [Go for App Engine](http://code.google.com/appengine/docs/go/gettingstarted/) |
| and Go more generally. |
