HackSource is a programming tutorial search engine that indexes thousands of books and tutorials from all over the interwebs. Search is available for subjects & resources. The typeahead interface displays results from both so you can quickly navigate to the content of interest. The site also uses basic natural language processing on tutorial titles and descriptions to create topic tags for each subject. Since the words “deployment” and “blocks” come up frequently in the 648 Ruby tutorials they are made available as topic filters.
