seaside - past, present and future
DESCRIPTION
Seaside does different to what is considered as best practices for Web development. It breaks with common best practices for Web development, such as to share as little state as possible, use clean and carefully chosen URLs, and use templates to separate model and presentation. This talk will give a short introduction to a Web framework that is different by design. It will demonstrate what can be won when breaking the common patterns of Web development. Moreover it presents how Seaside integrates with the latest technologies such as AJAX and Comet.TRANSCRIPT
