What Gems To Be Using For What Job in Rails 3 Right Now
I had to stick a new title on this post but basically it's a post by Andy Wang of Intridea that shares some current 'best choices' of gems and libraries to use for your Rails 3 apps in areas like authentication, scaffolding, forms, search features, and more. Very useful. For now.
Faster Rails Tests with Hydra (in Ruby 1.8)
Hydra is a distributed testing framework that speeds up your test runs by spreading the load between multiple machines (or even multiple processes on your own machine to use multiple cores). It's Ruby 1.8 only for now though.
Life After Objective C? MacRuby!
iOS developer Jonathan Penn ponders whether Apple is reaching a point where Objective C will be a barrier to introducing more developers to their platform. His theory is that Apple will adopt MacRuby as a 'next step' solution.
Running Rails 3.1 and Sprockets on Heroku Right Now
Gerred Dillon of QuickLeft has been playing with Rails 3.1 and wanted to deploy a Rails 3.1 app (which depends on Sprockets for asset packaging) to Heroku. He hit some trouble (as you'd expect - Rails 3.1 isn't even out yet!) but found a workaround to get things running right now.
Rubinius on JRuby? It Exists.
Yoko Harada melted my brain with this post about running Rubinius on JRuby. Turns out, there's a Rubinius branch of JRuby to do just this and the Rubinius implementations of core classes then overrides the JRuby implementation. This is one for the experimental folks.
What's New in Edge: Scoped Mass Assignment in Rails 3.1
Protecting your attributes from mass assignment (whether by blacklisting or whitelisting) is an important safety feature in your Rails apps. Sometimes, though, you want different rules for different types of identified users. ActiveRecord has been getting exactly that functionality in Rails 3.1.

HTTP Streaming by RailsCasts
Ryan Bates presents the latest episode of RailsCasts where he looks at the much awaited 'HTTP Streaming' feature in Rails 3.1 that allows content to go out over the wire before the view is even completely rendered. Trippy.
O'Reilly's RailsConf 2011 Videos YouTube Channel
Highlights include Dr Nic playing the Top Gun theme tune, the handing out of Ruby Heroes awards, and Aaron 'tenderlove' Patterson kissing people. Yeah, it's a wacky bunch!

Active Admin: Gorgeous Admin Interfaces for your Rails Apps
Active Admin bills itself as the 'missing administration framework' for Rails apps. It's basically a plugin for generating administration style interfaces. It's not super new but has been updated recently and has a very compelling promo site.
Middleman: Static Site Generator on Haml, Sass, etc.
The Middleman is an ultra opinionated static site generator (think nanoc or Jekyll) that uses Haml, Sass, Less and CoffeeScript in order to kill 'tag soup' and encourage 'only the cleanest and efficient markup.'
Search Your GMail Messages with ElasticSearch and Ruby
ElasticSearch is an HTTP server version of the Apache Lucene search library (like the more famous Solr). Karel Minarik shows how to tie up ElasticSearch and your GMail account with some Ruby gems and a small Sinatra app to create a locally searchable archive of your GMail messages.
