Microblogging lets people share short status messages with their social network. Public Web sites like Twitter, Jaiku and Plurk are wildly popular with consumers, but Open Source programs allow a distributed social graph and implementation inside the enterprise firewall. Evan Prodromou, founder of Identi.ca, will describe the Open Source microblogging tool Laconica and its uses in the workplace and on the Public Web.

* Test Driven Development - What is it, why do it, what are the advantages?
* Future VMs will run JS faster, making "bigger", more processing intensive apps possible within a browser
* Traditionally web applications have most business logic running server side.
* Testing for server-side web applications has matured over the past few years
* This creates a growing need for testing at the browser level, but this area is still young and not as widely practiced
h3. What do we gain?
* Stable development - iterate without fear of breaking existing features
* Easier refactoring - rewrite the guts of your app and be confident it continues to work
* Speed - stop refreshing and clicking through your app to verify things are working, thats what computers are for
* Automation - repeatable tests help you do the right thing every time, without having to think about it
h3. Getting Started
* A simple example - a client-side form validation library and a suite of tests for verifying it works as expected
h3. Going further
* A complex example - integration testing, scripting user stories
* Testing across multiple browsers
* Incorporating JS tests into a larger development workflow with server-side tests
* Continous integration - running tests automatically, every time you commit

Django is a powerful open source web framework that leverages the expressive power of the Python programming language. Each piece is well-documented and there are tutorials showing how to create small pieces of functionality. But that's the small picture... how do you leverage Django's power and flexibility to solve real-world business challenges?
I'm a developer tasked with exactly this responsibility. I develop and manage systems for a small (but growing) consulting firm that needs to deploy powerful web-based solutions quickly and cheaply. Django is frequently my tool of choice.
105 minutes isn't nearly enough to fully explore Django, but it might be just the right amount of time to show how an experienced Django developer would plan and execute a solution to a real-world problem. I have a couple different projects in mind, but I expect that the elements of a good project would include:
For purposes of the session, I'd be assuming a "stock" Django installation with the standard templating, ORM, etc.
This would assume familiarity with Python and Django basics, but no experience beyond the basic tutorials.
Apache is no longer the only sensible open source web server choice. Lighttpd and Nginx, as well as a number of other contenders, have become popular and blogs are littered with quick & dirty benchmarks _proving_ which server is supreme. With a myriad of languages, platforms, and deployment options, there's very little way to tell which combination is right for your specific needs.
This presentation will measure a number of environments on a wide variety of metrics:
Benchmarking static files isn't really useful to anyone, so I'll test as many of the servers on as many of the following frameworks and applications as possible:
