  • rev=canonical bookmarklet and designing shorter URLs
    Kellan’s rev=canonical service exposes rev=canonical links using a server-side script running on App Engine. An obvious next step is to distil that logic in to a bookmarklet. I decided to combine the rev=canonical logic with my json-tinyurl web service (also on App Engine), which allows browsers to lookup or create TinyURLs using a cross-domain JSONP request. The resulting bookmarklet will display the site’s rev=canonical link if it exists, or create and display a TinyURL link otherwise:
