Car tracking in Smalltalk

Sven Van Caekenberghe reports about a new application "T3 Easy" (a track & trace product). It's an HTML5 web app (using client side HTML + Javascript + CSS) on top of a REST server written in Pharo Smalltalk. It consists of 4 stateless Pharo Cog VM's running behind an Apache load balancer.

The server uses Zinc HTTP Components, both for its server part, as well as for clients talking to other systems behind the scenes. Even the Open Street Map tile serving, which is pushing out many megabytes, is currently going through this server.

There is a live demo and a few classes are available as open source (IP to country mapping, ...)
