So did DHH give permission to use the Rails logo for this project????? "The use of the logo is restricted as it always is when talking about a trademark. When the logo is used in a commercial setting, such as part of the promotion of a book, it legally requires that the trademark holder has been involved and stands behind the quality of the book. If that's not the case, you're on the way to lose your trademark. So I only grant promotional use for products I'm directly involved with. Such as books that I've been part of the development process for or conferences where I have a say in the execution." http://www.rubyinside.com/david-heinemeier-hansson-says-no-to-use-of-rails-logo-567.html http://www.rubyinside.com/david-heinemeier-hansson-says-no-t...
