The basics of creating a tumblelog with Django (via) Ryan Berg suggests having a StreamItem model that links uses a GenericForeignKey to link to other content types, then using signals to cause a StreamItem to be created for every other model type. I should switch to doing that on this blog: at the moment I have to query three separate tables to build the tumblelog part which results in messy code for ordering and pagination.

Django snippets: Command to dump data as a python script. Extremely useful—dumps the data for an application as an executable Python script which will re-import it in to another database without any risk of colliding with existing IDs, sorting out foreign keys along the way.

mod_rpaf for Apache. A more secure alternative to Django’s equivalent middleware: sets the REMOTE_ADDR of incoming requests from whitelisted load balancers to the X-Forwarded-For header, without any risk that if the load balancers are missing attackers could abuse it to spoof their IP addresses.
