PyAMF 0.3.1 was released this week, just in time to meet the increased interest on Python and RIA generated by the recent preview release of Google App Engine and the announcement of Adobe's Open Screen Project.
PyAMF is an open source project that provides action message format (AMF) support for Python. This allows for AMF-based communication between Python-powered Web servers and rich Internet application (RIA) clients in Flash, Flex or AIR.
Google App Engine (GAE) enables users to build Web applications on the same scalable systems used by Google, so that they can expand from one user to millions of users without the need to rebuild infrastructure. The release of PyAMF 0.3.1 improves support for GAE and introduces a new AMF gateway for GAE Web applications.
Adobe's Open Screen Project further opens core Adobe data/file formats, such as SWF and FLV, the fundamental elements for Flash/Flex-based RIA applications. Adobe Integrated Runtime and Flash Player use AMF for communications between an application and a remote server. AMF encodes remote procedure calls (RPC) into compact binary representations that can be transferred over HTTP/HTTPS or the RTMP/RTMPS protocol. PyAMF enables the development of Flex-based RIA applications along with a GAE backend, thus putting RIA into the Google cloud computing platform.
With the 0.3.1 release, PyAMF offers many special features, including:
Aral Balkan, the ARP Flex Framework creator, has already taken PyAMF, GAE and Flex into account. Balkan has announced a GAE SWF Project that uses PyAMF and is “a resource of Flash and Flex-related knowledge specifically aimed at getting you up and running quickly with Google App Engine, a wonderful platform for building and deploying massively-scalable Flash and Flex applications.”
Other examples of PyAMF/ GAE projects include Flex Python Shell and PyAMF Test Suite.

Thin client paradigm characterized by web applications is a kludge that needs to be repudiated. Old compromises are no longer needed and it's time to move the presentation tier to where it belongs.
In this presentation filmed during QCon 2007, Jeff Sutherland, the creator of Scrum, talks about his visit at Google to do an analysis of Google's first implementation of Scrum.
In this article, Bryon Jacob and Chris Berry introduce AtomServer, their implementation of a full-fledged Atom Store based on Apache Abdera, which is now available as open source.
It is easy to think that virtualization applies only to servers. In reality the recent resurgence of the concept is also being applied to networking, storage, and application infrastructure.
In this article, Stefan Tilkov explains some of the most common anti-patterns found in applications that claim to follow a "RESTful" design and suggests ways to avoid them.
In this article, Adrien Louis and Marc Dutoo discuss the differences and relative merits of using orchestration vs. routing in a typical ESB setup, and discuss various implementation options.
Wayne Lund discusses batch processing, Spring Batch objectives and features, scenarios for usage, Spring Batch architecture, scaling, example code, failures and retrying, and the future roadmap.
Developer Jay Fields draws on his experiences as a ThoughtWorks consultant to describe effective user story estimation techniques.
