A kind person wrote me an e-mail asking me to make an improvement on a little known but often stumbled-upon section of my web server, the Shanghai Bus Routes in English project. The project's big failing is that it has always lacked a way to search the routes for a specific stop.

The letter-writer's idea was simple and elegant: generate one giant web page with all of the bus routes on it and let the web browser do the searching. So I got to work and 10 minutes (cat and a few of emacs' query-replaces) later I have a working product. Be careful, though, it is almost one megabyte in size so if you intend to use it often it is better to download a copy to your own computer.
