Delete all your CouchDB databases:

rm -Rf /usr/local/var/lib/couchdb/*

URL to browse CouchDB databases: 127.0.0.1:5984/_utils

Append to Files using Gsub¶ ↑

def gsub_file(relative_destination, regexp, *args, &block)
  path = destination_path(relative_destination)
  content = File.read(path).gsub(regexp, *args, &block)
  File.open(path, 'wb') { |file| file.write(content) }
end

Create Attributes Accessor Dynamically in Ruby¶ ↑

params.each do |key, value|
  self.instance_variable_set("@#{key}", value)
  self.class.send(:define_method, key, proc { self.instance_valiable_get("@#{key}") })
end

	(0...10).collect { chars[Kernel.rand(chars.length)] }.join

	# Rebase
	$ git commit -a -m "Commit message"
