GWT and Seaside: steps in the right direction for increasing developer productivity
Google Web Toolkit (GWT) and Squeak Smalltalk based Seaside are pleasant exceptions. Just like using Rails, GWT and Seaside provide that pleasant "everything just works" experience and great interactive development environments.
Seaside also supports the same fluid interactive development style: changes made in a Squeak Smalltalk source browser are immediately reflected in running web application. Seaside uses continuations to provide a more linear programming model. Blocks of code are used instead of URLs; inside a code block, you can call another code block - after a "return", you continue where you left off in the first code block. There is a performance penalty for using continuations, but it looks straight forward to run multiple Squeak processes behind Apache so it look like Seaside scales the same way that Rails scales. DabbleDB is written using Seaside - a great proof of concept for scaling.
