This script installs a patched version of ruby 1.9.3-p194 with patches for boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.
Huge thanks to funny-falcon for the performance patches.
This is an experiment for possible faster boot time (and consequently faster feedback) when running tests. I ask your help to try this in your apps (any Rails 3.x app) and let me know how well it works.
Add the following lines inside the configuration block in config/environments/test.rb:
config.cache_classes = true
def eager_load!; end
This allows you to use the following video streaming services outside of the US from your Mac without having to use a proxy or VPN, so no big bandwidth issues:

| # bash generate random 32 character alphanumeric string (lowercase only) | |

I have bemoaned the lack of a ViewModel in Rails many times, and I prefer using Presenters to simulate a ViewModel. But it turns out there is an object that does represent the state of the view in Rails apps. Its an instance of ActionView::Base that the controller calls view_context. We don't have much control of this object, but it seems like a logical place to put our view-specific behavior.
This code is an attempt at creating Presenters using modules. The module will be mixed into the view_context object. This is very similar to how a Decorator module will be mixed into a model object, only instead of being specific to the model is it specific to the view.
This means that testing your presenter is no different than testing any other module. So relying on dependencies such as other methods or instance variables can make testing difficult.
| # This allows developers to pass an Active Model object | |
| # to within, check and uncheck. This is very useful when | |
| # used with `content_tag_for` since `content_tag_for` | |
| # generates an unique dom id for each object. With this | |
| # module, we can write: | |
| # | |
| # within comment do | |
| # click_link "Destroy" | |
| # end | |
