¡Buenos dias Django Round-Up readers! Here's issue #6 with lots of PyCon goodness:
Featured
Today's round-up starts on a horribly somber note. The Django community lost one of its leaders last week when Malcolm Tredinnick passed away. He was an amazing person and the
tributes
poured
in from
everywhere
. Rest in peace Malcolm, you will be missed.
Django BDFL Jacob Kaplan-Moss gave a talk at Heroku's Waza conference about the Django ecosystem and how stable APIs have fostered its growth. He draws an interesting analogy between Django and the tractor he has on his farm. Well worth the watch.
The Python.org redesign team released an early preview of Python's new site at PyCon last week. Sign up at the site to become a beta-tester and help shape the future of Python.org. The site is using the new Python 3.3 support in Django 1.5.

Like it or not, Python 3 is upon us. In this video from PyCon, Jacob Kaplan-Moss talks about his experience porting third-party Django apps to Python 3 and shares techniques to make it as painless as possible.
With Django 1.5 out the door, work has already begun on 1.6. One of the first big features is greatly improved database transaction handling. If you ever fiddled with the
autocommit
option in the past, this one is sure to make you happy. Excellent work by Aymeric Augustin handling this nearly single-handedly and closing out a slew of issues in the process. The
diff is impressive

A great intro presentation on testing in Python by Carl Meyer. If you've been holding off on learning how to test your code or never knew why it was important, watch this talk. Even if you're an old hat with TDD, you might learn something new here.
NewRelic Python engineer, Amjith Ramanujam, shows off some of the profiling tools Python has to offer and how you might use them in a real-world scenario.
A modern Django web stack requires lots of processes, a web server like gunicorn which forks off a few workers, a task queue like celery which forks off a few more, maybe a Redis instance, etc. Everything is managing it's own processes, then you have another process like supervisord, upstart, or monit to manage all that. Circus, from the folks at Mozilla, is a different take on that stack offering more flexibility and visibility into what your processes are doing.
Another tool coming out of Mozilla, Fancy Cache is Django's
cache_page
decorator on steroids. It's developer, Peter Bengtsson, also released
mincss
a tool that will analyze your page for unused CSS selectors. He uses them both on his site to actually inline the exact CSS that each page uses.

Django added the
staticfiles
app a few versions back, but there is still a lot of confusion on how it works. If you're new to Django or haven't been following along closely, this post goes in depth on exactly how to use it and when specific settings come into play.
