We just released RailsDeveloper, which gives developers a place to share resources, ask questions, help others, review books, watch videos, and control what content bubbles up onto their radar.
In this tutorial, I described the steps I did to deploy a simple Rails 3 application to Tomcat using JRuby. In addition, I show a way to make your Rails 3 application run side-by-side with a JRuby-based version.
I also included the problems I encountered along the way and how to solve them.

home_run is an implementation of ruby's Date/DateTime classes in C, with much better performance (20-200x) than the version in the standard library, while being almost completely compatible.
I wrote a little blog post that shows the implementation of three helpful "magical" constants:
* OS: returns the current operating system
* RubyEngine: returns the current Ruby implementation
* RubyVersion: returns the current Ruby version
* OS: returns the current operating system
* RubyEngine: returns the current Ruby implementation
* RubyVersion: returns the current Ruby version

You might want to upgrade an existing Rails 2.3.x project to the newly released Rails 3. If you saw in BDDCasts's URLAgg updates series how to get the specs to pass, now it's time to move on and get Cucumber features to pass. Check episodes six and seven for details on upgrading a project using Cucumber to Rails 3.

Sometimes just DRY the controllers is not enough, a lot of the resources often share the same views, wouldn’t it be nice to have view files DRY’ed too? You can! Inherited Resources Views is an extremely easy to use plugin to DRY the views associated with your inherited resources controllers. It is library-agnostic (it only depends on Inherited Resources) and it supports generating both erb and haml templates. Source code available at: http://github.com/fredwu/inherited_resources_views
I've created a brand new pure Ruby memcached client gem, Dalli, which is designed to replace the memcache-client gem. It drops right into Rails 3 and supports Ruby 1.8, 1.9 and managed environments like Heroku.
We just launched simple_currency, a tiny but smart currency converter. Ruby 1.8, 1.9 and JRuby compatible. Check out the github repo as well and feel free to contribute!

Jeremy McAnally has just announced he's reduced the price of his Rails 3 Upgrade Handbook to $9 (from $12) for the next 3 days in celebration of Rails 3's release. I read it a while back and.. it's good - check it out.
Disqus is a great plug-n-chug commenting system, but it's lacking a few very useful features: Markdown support, code pretty printing, and callbacks to tell you when a comment has been added or edited. And getting the comment/reaction count for the current page or linked posts is overly complicated and/or not-well-documented. This jQuery Disqus Plugin hopefully simplifies the Disqus installation process while adding several helpful features.

I just launched Yet another ObjectMother pattern implementation for rails testing - Famili. Diff from factory-girl & machinist is usage plan ruby classes for factories/mothers which can be put in rails/lib and give extensibility and rails dependency management. I did it for using them in front-end testing with complex factories. If u have some ideas contact me.
I just finished writing a simple (and extensible) helper for displaying data called Objectastic. It's kinda like form_for but for data display, not data entry or editing. For rails 3, but should work with rails 2.3.x ... maybe

Delayed::Job and Resque are excellent ruby gems, but they require substantial funds and/or time to setup on Heroku or Slicehost. High cost/effort prevents bootstrapped startups from building apps that need background processing, like aggregators. So I've hacked together a template Sinatra app that uses GAE to give you free Cron and Task-Queue functionality on Heroku.
Ruby|Web Conference is right around the corner! It's September 9-10 at Snowbird Resort in Utah. You can also hear my interview with conference organizer Mike Moore here.
I just wrote a short piece about how to get someone started with Rails. I'm using a simple "do it yourself" 3-part strategy that involves pushing them in head first and seeing if they can swim ;) I'm curious if anyone else has experience with this kind of thing, though. Comments and suggestions are more than welcome!
