How to recognize the Ruby on Rails framework on a website?

Question

Ruby on Rails

There is a desire to view examples of sites, applications written on the Ruby on Rails framework.
Is it possible to determine from the source code of a web page (html) through a browser that the site is running on Ruby on Rails? For example, along the paths of the css and images files. If not, what are the ways?

1 sign - if the developer uses the Asset Pipeline, then the name of the compressed css or js file is something like /assets/application-2742d3db28fd49e148cb335459acc8b1.css.
This can be seen on the same freelansim.ru, which is written on rails.
Sign 2 - a site written on rails has a cookie with a session hash like _session_name.
Of course, the developer can change this, but most still use the Asset Pipeline.

Answer 3

twitter at the very beginning worked on rails, github / gitlab are also written on rails (at least gitlab) ... I have little idea what you want to see - RoR is still a framework and not a CMS.
