There will probably be better solutions as we become more experienced with using Bundler, and more command line tools become Bundler-aware.

b will use bundle exec if there is a Gemfile in the working directory, and run the call without Bundler otherwise.

This script is part of our geordi gem on github.

A jQuery plugin that sets a div or span to show a countdown to a given time

This post explains, in some detail, how we will implement a nice performance boost for Rails developers. Understanding the details might help gain the full benefits of the optimization, but you will gain some benefits even if you have no idea how it works.

Capistrano task for Bundler.

jQuery plugin for attractive image rollover captions on hover, adding simple animated text overlays to images.

This gem is designed to provide CSS views to Rails, and a process to concatenate and minify these files to one file for production.

Physical servers worked, EC2 did not.

Remove a mistakenly added file from the staging area while keeping local changes; git reset HEAD path/to/file also works for conflicted files.

The ECB has an XML feed with EURO exchange rates to other currencies. It is updated daily.

Rake tasks can report exceptions to Airbrake without notifying in development or test environments, using the usual notification rules for tasks that depend on :environment.

In a great post about named routes in Rails, path vs. url, Viget Labs ponders which variant is best used.<br />
<br />
Most often we use foo_path, which when used in Rails URL helpers will generate a relative path, where foo_url generates a full URL. In most cases the path makes most sense, but not always.

The box shadows created rendered in IE by CSS3PIE look darker and are blurred differently than in browsers that render box-shadow natively.

If possible, try to be OK with this. If not, make an IE-only stylesheet that uses a different color and blur radius:

// Real browsers:
+box_shadow("0 4px 10px #bbb")

// IE with PIE:
+box_shadow("0 5px 15px #888")

We should try to package this solution in a neat way so we don't need different stylesheets.

with_state from state_machine can break in complex scope chains; a custom having_state scope keeps record filtering reliable.

Cached web fonts can still cause a flash of unstyled text during loading.

Bundler support for Rails 2.3.x requires updated RubyGems and Passenger, a bundled Gemfile workflow, and bundle exec for tests and deployment.

Rails XSS protection can escape ActionMailer email bodies unexpectedly. A configuration initializer prevents rails_xss from escaping mail content.

One option is to use partials. Or you can set the @template field to the name of another action:

class Mailer < ActionMailer::Base
  def foo
    subject "Hello World"
  end
  
  def bar
    subject "Hello Universe"
    @template = 'foo'
  end
end

Unexpected executable bits can appear on normal project files after copying from Windows or a Samba share. geordi remove-executable-flags clears them recursively with chmod -x.

Child elements’ bottom margins can create unwanted inner spacing in boxes like sidebars. A Sass mixin removes the last child’s bottom margin; older IE needs a class fallback.

You may omit the /path/to/link_name to have a link with the same filename appear in the current directory

ln -s /path/to/file /path/to/link_name

unlink link_name       // to remove the link and not where it is pointing at

With this plugin, you can create a scalable tooltip by just using a single background image for the tooltip body.

Prototip allows you to easily create both simple and complex tooltips using the Prototype javascript framework.

Please note: "Permission to use Prototip on your domain is required and can be obtained by paying a small fee."

The point is, evented I/O is not magic scalability pixie dust, and like anything, there is a tradeoff.
