We’ve been hearing great things about Merb routing so a few weeks ago, we wanted to see if we could get it working in a Rails application as a proof of concept.  The goal of this project was to use the Merb routing engine along with router.rb and without touching any of our existing Rails [...]

Here’s a proof of concept plugin that will monkeypatch Rails or Merb routing to allow you to define “acts as blocks” anywhere throughout your application (i.e. a plugin) and then use them in your routes file.
Imagine the plugin acts_as_commentable defines the following in its init.rb:

ActionController::Routing.routes_for_acts_as(:commentable) do |map|
map.resources :comments
map.best_comment ‘/best-comment’, :controller => [...]

In the previous post, I did some JRuby testing and noticed perf improvements over time.

We ported our Rails application to JRuby in order to do some GC comparisons yesterday. Not a ton of changes required. Mostly replacing gems with native dependencies. YAML is a bit more strict than its MRI counterpart…. but all told, thats pretty amazing! Nice job JRuby crew!

Beforehand, monit would restart instances a handful of times a day. After Rails 2.2, monit restarted instances THOUSANDS of times a day.
This is a graph of one of our haproxy instances a couple days ago.

We looked at everything, including time spent [...]
