rev=canonical bookmarklet and designing shorter URLs

Simon Willison has an awesome post up talking about his rev=canonical bookmarklet, and designing shorter URLs by casting unique IDs to base 62 (We’re using the same trick on flic.kr to avoid having to maintain a look up database, though we’re using base 58). He details designing his new short URLs, deploying them on Django, and built a handly bookmarklet.

The nice thing about this approach is that it makes it trivial to add custom URL shortening domains to other projects—a quick view function and a few lines of nginx configuration are all that is needed.

Bookmarklet: Shorten (drag to your browser toolbar)
