I'm pleased to announce the release of djangoembed, a django app for consuming and providing rich media.

What is OEmbed?

OEmbed is a format for allowing a rich representation of a url. If you've used Facebook you've probably seen this feature before -- linking a YouTube video will embed an actual video player in the news feed, automatically. The player is represented by some HTML, plus there may be additional metadata like the author, a link to their channel, the title of the video, or even a thumbnail.

Last week, after several false starts, I moved all the sites I maintain into virtualenvs, with their own pip requirements files. My reasons for doing so are pretty simple:

• Experimenting with new/different versions of software is a pain in the ass without isolation
• A pip requirements file for each site is a very nice thing to behold
• I symlink 3rd party apps into a custom directory on my PYTHONPATH and it was getting huge
• Profit

There are quite a few great tutorials out there for getting started with these tools. I will only discuss how I got over some of the hurdles involved in using these tools, as well as a tool for automating the creation of "skeleton" django sites.

Apache Solr is a fast, open-source search solution. People are doing some very cool things with Solr. I personally have only begun to scratch the surface of what is possible with Solr, but have seen amazing returns with a relatively small investment (thanks entirely to Daniel Lindsley's excellent search framework, django-haystack). There are instructions for getting up and running with Solr + Jetty -- the purpose of this blog entry is to walk through setting up multi-core Solr with Apache Tomcat.

To get the benefit of Django 1.2's new CSRF protection, all POST forms will need a special token. Here is a quick command that runs through templates adding the token:

find . -type f -name "*.html" -exec sed -i \
's|\(<form[^>]*method="post"[^>]*>\)\({% csrf_token %}\)\?|\1{% csrf_token %}|g' \
{} \;

This post will be very brief, but I want to show a little trick I'm using on my different servers so I can tell them apart at a glance. I use a custom bash prompt which gives the hostname of each server a different color:

[charles@alpha ~] $
   
[charles@beta ~] $
