{Marlowe}[https://github.com/KineticCafe/marlowe] is a Rack middleware that extracts or creates a request ID using a pre-defined header, permitting request correlation across multiple services. When using Rails, Marlowe automatically adds itself to the middleware before <tt>Rails::Rack::Logger</tt>. As of Marlowe 3.0, a Faraday middleware is provided (<tt>require 'marlowe/faraday'</tt>).

Nesta is a lightweight Content Management System, written in Ruby using the Sinatra web framework. Nesta has the simplicity of a static site generator, but (being a fully fledged Rack application) allows you to serve dynamic content on demand. Content is stored on disk in plain text files (there is no database). Edit your content in a text editor and keep it under version control (most people use git, but any version control system will do fine). Implementing your site's design is easy, but Nesta also has a small selection of themes to choose from.
