Beyond Web 2.0 - Django and Python in the modern web ecosystem

Django is over 10 years old; but the web that it was built for doesn't really exist any more. Yes, we still need to rapidly develop database-backed websites, and we still need those sites to use AJAX, but the modern web is faced with new problems, and new challenges. Many of those challenges involve interacting with devices that aren't desktop machines, and platforms that aren't a traditional browser - places where Python isn't a first-class citizen.

Does this mean we have to abandon Django and Python for other frameworks and languages? Can we keep using Python and Django on the server side and interact with independent client side frameworks? Or can we push Python and Django into these new environments?

In this talk, Dr Russell Keith-Magee will explore the problems, and some potential solutions, to these problems.

Comprehensions in Python the Jedi way

by Bjørn Friese

Beautiful is better than ugly. Explicit is better than implicit.

-- The Zen of Python

I frequently deal with collections of things in the programs I write. Collections of droids, jedis, planets, lightsabers, starfighters, etc. When programming in Python, these collections of things are usually represented as lists, sets and dictionaries. Oftentimes, what I want to do with collections is to transform them in various ways. Comprehensions is a powerful syntax for doing just that. I use them extensively, and it's one of the things that keep me coming back to Python. Let me show you a few examples of the incredible usefulness of comprehensions.

Django ORM Optimization Tips

Caveats:
* Only use optimizations that obfuscate the code if you need to.
* Not all of these tips are hard and fast rules.
* Use your judgement to determine what improvements are appropriate for your code.
