Progressive Enhancement with Prototype and Custom HTML Attributes
One of the nifty things progressive enhancement can be used for is to allow you to markup your document in a way which allows behaviors to be added to it automatically. Most commonly, this is done by specifying a class name on those elements that you want to enhance. However, this approach does not let you easily pass additional information such as parameters to your enhancement code.
An approach to this problem is to use HTML attributes to mark elements, and Prototype makes this technique easy to implement and work across browsers.

jRails: Ruby on Rails with the Prototype guts ripped out
My esteemed colleague Noel Rappin sensibly advocates doing things the Rails way whenever possible. As a Rails noob, I should follow his advice. But as a dedicated user interface developer, I'm already finding that many of the best practices of my discipline take extra steps to enforce in Rails. Case in point: The ability to write unobtrusive JavaScript using my tool of choice, jQuery.

Why Does Scriptaculous Need Prototype?
I've been going through the Scriptaculous effects library in some detail. After grokking all there is to know about effects queues, I was left with one question: why does the effects library have a dependency on Prototype? The dependency could be removed with maybe two dozen lines of Javascript. So, why the dependency?
After having several other frameworks arm wrestle me for the $ identifier, I'd like to drop Prototype at the nearest corner.
Anyhow, I'm working on something involving Scriptaculous now that will likely make me the but of both jokes and death threats. Stay tuned.
