Railroad “is a standards-based repository for large binary files such as digital media, along with their metadata. It is designed to be easy to integrate with content management systems and other client software. Railroad uses the industry-standard Apache HTTP server. It uses Apache’s mod_dav and mod_python, and metadata is stored in a PostgreSQL database.”

A couple of projects I haven’t mentioned before:

Python Director: a pure-python TCP load balancer. It takes inbound TCP connections and connects them to one of a number of backend servers.

PyWebLog: Not a project, per se, but a great comparison of Python web frameworks. Basically, take a problem, and code in up in different frameworks, to see what’s what. And blog about it, so that we can follow along from the stands. Great job…thanks!
