Scheduler needs very little cpu, just start it with a worker.
desc "schedule and work, so we only need 1 dyno"

Make your rspec output look more interesting!
(yes we had too much spare time at our hands… 
)
# spec/spec_helper.rb
# encoding: UTF-8
if defined? RSpec::Core::Formatters::ProgressFormatter
RSpec::Core::Formatters::ProgressFormatter.class_eval do
DOTS = ['☘','⚘']
def example_passed(example)
output.print green(DOTS[rand(DOTS.size)])

A small snippet to interact with commandline applications that ask questions on stdin, particularly useful for testing.
Usage
interact "rails new foo -m template.rb", /RSpec/ => 'y', /MySql/ => 'n'
Code
# https://gist.github.com/2166521
# capture commandline output and send responses if nothing was read
def interact(command, answers)
puts command
line = ""
write = false
PTY.spawn(command) do |output, input, pid|
loop do
rs, ws, = IO.select([output], [input])
# read into the buffer
if r = rs[0]
write = false
ret = r.read(1)
print ret
return unless ret
line << ret
line = "" if ret == "\n"
end
# time to write ?
if w = ws[0]
if write and line != ""
text = line.gsub(/\e\[\d+m/,'').strip
answer = answers.detect do |question, answer|
text =~ question
end || raise("Question #{text.inspect} has no answer!")
w.write(answer.last + "\n")
line = ""
else
write = true
end
end
end
end
$?.success?

If your environments/*.rb look like a repetitive mess, its time to get a config.yml!
- overview of your configuration
- dry code
- (optional) not check in all the passwords/keys of your app (only check in config.example.yml), great for open-source apps
- Can be loaded without loading the environment (e.g. small rake tasks)
# lib/cfg.rb
CFG = YAML.load(ERB.new(
File.read("config/config.yml")
).result)[Rails.env].with_indifferent_access
# config/application.rb
require "cfg"
# config/config.yml
