Eric Mill has released another version of his excellent Jester javascript library. Jester attempts to mimic the ActiveResource API in Rails through javascript. I have spent a fair amount of time going through the Jester code base, making suggestions and writing example code to be adapted by Eric in the last week, and I must say Eric has done a tremendous job rounding out this library with many highly anticipated features.

On another note, Jester now includes a pruned and packed version of a Date library I put together to use in my applications. I have decided to release it under the MIT License along with Jester. Over the next week I will put together a post to describe it's functionality in detail, but for now you can get the full version of the library in my SVN repository.

You would think that there would be a defacto acts_as_addressable plugin out there given all of the articles on polymorphic associations using the address analogy. When I wrote this plugin I couldn't find a plugin to do this. So here it is, acts_as_addressable, the not so new plugin.
I was in the process of writing a new application and wanted to add phone numbers to a particular model. So I wrote a plugin to do it. Introducing acts_as_phoneable. It is not a technically complicated plugin, but according to a google search for "acts_as_phoneable" there is nothing out there. Take a look at the README for usage informatio. Enjoy.
Today I stumbled upon a nice tutorial written on Matthias Georgi's blog about using the Script.aculo.us Autocompleter.Local to reduce calls to the server when using an auto_complete_field in Rails. I had the same issue with a Rails app I was writing a while ago and solved it using a similar solution. I wrote a plugin to allow me to reuse the code at will. After reading Matthias's post I decided to update the plugin to use some of his "tricks". So here it is...

Thanks Matthias!
