The upcoming release of Adobe AIR will provide support for UDP sockets, allowing you to send and receive messages using the Universal Datagram Protocol (UDP).
We created an example, using Adobe AIR 2.0 and the PyAMF and Twisted libraries for Python, that echoes ByteArray messages every x seconds to a Twisted UDP server. The example application also enumerates available hardware and software network interfaces on the client computer using the new NetworkInfo API.

Dave Thompson created a new address book example that uses the new SQLAlchemy adapter that was added in the latest release of PyAMF. PyAMF provides Action Message Format (AMF) support for Python, mainly used in the Adobe Flash Player for RPC communication.
You can browse or download the source from the Subversion repository. You can find instructions on how to run the example yourself on the documentation page.
There are two parts to PyAMF: the core AMF encoder and decoder, and the gateway/remoting for transporting data between a server and a client.
Currently both parts are written in pure Python but the idea is to create a C version of the AMF encoder/decoder that can be used as a dropin which will increase performance significantly.

Google did the Ajax version of the Python shell, running on Google App Engine, we present you with the Flex version (click image to view the sample):

The 0.3 release tree has been mostly about building up compatibility with Google’s App Engine.
Because the environment that Google exposes to the developer is quite restricted (for obvious reasons!) we thought it best if we get the entire PyAMF test suite (up to 430 individual tests and counting …!) running.
We have built a simple web app that runs the PyAMF test suite from within the Google App Engine. Its a work in progress and isn’t planning on winning any beauty contests, but works nicely.
Ohloh is a website which provides a web services suite and online community platform that aims to map the landscape of open source software development. The Ohloh API is a free, REST-based programming interface to the Ohloh open source directory. You can use the Ohloh API to create your own applications and web services based on Ohloh data. There’s a Python example client and additional examples are available for Java, Ruby, Bash, Perl, PHP and C++.
I decided to create a simple AMF gateway using PyAMF that pulls the account data from Ohloh and then passes it to a Flex application. The reason I use a AMF gateway is because I don’t want to hardcode and expose my API key in the Flex client application, which could be decompiled easily, allowing others to abuse my key.
You can test their API by entering the emailaddress of a registered Ohloh user in the input text-field below, click Submit, and it will display the user’s general account info and load the user’s avatar.
After Google’s announcement on Monday we received a lot of questions about running PyAMF on the Google App Engine so we decided to start working on a tutorial. This is a work in progress and might require some updates to the library. We’re also planning on setting up a demo site on our appspot but more on that later.
The Socket class enables Actionscript to make socket connections and to read and write raw binary data. This example shows how to:
