I think most of you have read the book 《Thinking in Java》 although I feel so headache to read books like this. The author Burce Eckel have written an article 《Concurrency with Python, Twisted, and Flex》 which introduce how to parallel encoding by use of PC or CPU, and how to add user interface by Flex.
The article very excellent if you are interested please read it here. Following is a part of the article.
The speed of development in Python is deeply satisfying;……This is also true when building user interfaces in Flex — one can rapidly build the UI using Flex Builder and quickly wire it into your Python application using Twisted.
