Rails view helper for stripping whitespace between elements. Very useful for using `display: inline-block`.
module ApplicationHelper
def inline_tag(*args, &block)
body = Nokogiri::HTML(capture(&block)).at_css('body')
# First-level text nodes
body.xpath('text()').each do |node|
node.content = node.content.strip
end
content_tag(*args) { body.inner_html.strip.html_safe }

Got tired of using `if ($("#foo").length)`, so I wrote these helpers.
// Helpers
$.fn.isPresent = function() { return this && this.length > 0 }
$.fn.isBlank = function() { return typeof(this) == "undefined" || !this || (this && this.length == 0) }
// Examples
$("body").isPresent() // => true
$("#foo").isPresent() // => false
$("body").isBlank() // => false
$("#foo").isBlank() // => true

Clear Rails cache store and do it fast (without loading the whole Rails environment)
# bundle exec rake cache:clear
namespace :cache do
desc "Clear Rails.cache"
task :clear do
Object.const_set "RAILS_CACHE", ActiveSupport::Cache.lookup_store(Rails.configuration.cache_store)
Rails.cache.clear
puts "Successfully cleared Rails.cache!"
end
end

Change I18n.locale just for the time of a block
module Kernel
# I18n.locale = :en
# with_locale(:fr) do
# I18n.localize(Time.now, :format => :long) # => "mercredi 22 août 2012 13:23"
# end
# I18n.localize(Time.now, :format => :long) # => "August 22, 2012 13:23"
def with_locale(locale)
old_locale = I18n.locale
I18n.locale = locale

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

This is how I handle snappy taps on iOS.

This is how I handle snappy taps on iOS.

I create a little jQuery/Zepto “plugin” function:

$.fn.onClickOrTouch = (callback) ->
  if window.ontouchend != undefined # insanely clever touch detection
    this.each -> this._touchMoveCount = 0
