Messaging is a well established domain in information technology and can greatly improve the scalability and throughput of a system when employed appropriately. Message queues can be used to achieve

• spatial decoupling i.e. the systems that produce and consume messages may be deployed on different machines, networks, continents etc.
• temporal decoupling i.e. a system can enqueue a message and carry on without waiting for the message consumer.

We use e.g. messaging in [http://openquake.org] OpenQuake to distribute calculations of [http://openquake.org/about/gem/] seismic hazard and the respective risk to human lives and infrastructure.

There is a huge number of messaging patterns identified in the industry [7] and a small selection of these will be presented to whet your appetite :-)

AMQP [1] is a fairly new and open messaging standard with a number of freely available open source message brokers (RabbitMQ [2], ZeroMQ [3], qpid [4] etc.) with different features and performance trade-offs.

In the course of the presentation you will be
* introduced to AMQP concepts and jargon
* introduced to available Python AMQP bindings (focussing on an asynchronous (txAMQP [5]) and a synchronous variant (most likely kombu [6]))
* shown code examples demonstrating how to use these Python bindings

The presentation (45 minutes in total) is structured as follows:
* 7.5 minutes for messaging concepts and patterns
* 7.5 minutes for AMQP concepts
* 5 minutes for an overview of the Python bindings for AMQP
* 10 minutes for txAMQP examples (asynchronous bindings)
* 10 minutes for kombu examples (synchronous bindings)
* 5 minutes for questions

This talk will give an outline of the advances that Google have made in API delivery over the last year, and how it is relevant to you as a Python developer. The talk is suitable for beginners and advanced developers.

We will describe the underlying platform, and the built-in features that all Google APIs inherit.

We will focus on how the Python libraries for this API platform are generated and can be used as a single library that doesn't require updating with API updates, as Python lends itself perfectly to the nature of this platform.

This talk will cover:
- How to use OAuth into your webapp so users can give permission to access their data stored in third party web application.
- How your webapp can interact with their Web API using RESTful JSON protocols.

This talk is suitable for beginners already familiar with any WSGI web framework.

This talk will be illustrated with code samples using Google App Engine and Google APIs client library.
