Data-Transfer Objects Are a Disease. Meet the Cure.
by Aaron Oliver
Data Transfer Objects (DTOs) are commonplace. Every time you want to shuffle data and be object-oriented about it, you crank out a new class. But then someone extends it for their purposes. Badly. Then someone ELSE extends it AGAIN and makes thing worse.
Learn what makes our brains want to create DTOs, how they've been (ab)used in the past, and how Python's namedtuple makes it all better.

PHP to Python with No Regrets
by Alex Ezell
At Emma, we are transforming an eight year old PHP codebase into an API-driven service written in Python.

Django and Google App Engine: Why I'm using Flask and Amazon EC2
by Ben Rousch
I'm a lazy coder, but not the good kind of lazy. I dove into Django so I could have one web framework that would work on many kind of hosting setups and for any kind of web project. With some modifications, I could even use the laziest application host, Google App Engine. Some of these decisions didn't work out, so I'll share some of the lessons I've learned the past year or so.

Names, Objects, and Plummeting From The Cliff
The assignment statement is often the second thing a new Python programmer learns, right after the "print" statement - but the beginner can get seriously bogged down in all of the concepts that assignment involves! Using a simple analogy, this talk will tackle those issues head-on.

Bringing Modern Python to the Atari
by Jeffrey Armstrong
The Atari ST continues to fulfill a niche in the computing world amongst hobbyists. Porting CPython to the 32-bit Atari platforms and clones introduces a number of challenges related to incomplete Unicode implementation, threading issues, and dealing with shared libraries. The attempt at porting Python 2.7.1 and the addition of an Atari-specific Python extension will be discussed.

Consuming Web APIs with Python
by Issac Kelly
Issac will go over the basics of HTTP apis, what to look for, basic authorization methods, and how to interface with them in your python scripts. There will not be cake.

Squinting at Python Objects
Python classes can gain attributes as if by magic. Thanks to properties, descriptors, and (if all else fails) ``__getattr__()`` and ``__getattribute__()``, the attempt to access ``obj.something`` can result in arbitrary code execution. If you are wondering how your Python program is using memory, this can result in a problem: each time you look to see if something is there, it *is*, because it is pulled in dynamically the moment you look for it. In this talk, you will learn how to prod Python objects gently, and hopefully learn their secrets - and their memory usage - without actually invoking code.

Python 102
by Michael Yanovich
Now you know the basics of Python. What can you do with Python? Well the better question should be "What can't you do with Python?" In this tutorial/talk we'll cover more advance topics that include how to use the Python Standard Library, advance data type manipulation, and basic network programming. This class will be more like a talk depending on the comfortability of everyone in the class

Procedures, Objects, Reusability: "httplib", "urllib2", and Their Discontents
Python supports two major programming paradigms: procedures, and object orientation. This talk will claim that, when it comes to code re-use, these two paradigms are NOT created equal: because object-oriented programming encourages the programmer to write methods that consider everything else inside of "self" to be fair game, it encourages highly coupled code that proves brittle when extended.

Using Fabric - from a sysadmin's perspective
by Morgan Goose
Fabric is a great tool written in python for python devs. It allows you to script remote interactions on a remote server and only requires ssh and a shell on the remote host. It's commonly pigeonholed into a deployment tool, but it can but used for more than just websites.

HTSQL is a WSGI reporting toolkit for Relational Databases
by Clark Evans
HTSQL is a URI-based high-level query language for relational databases; it is written in the Python language. HTSQL is a wonderful complement existing WSGI-based applications, making it trivial to create interactive dashboards, complex reports. We use HTSQL as a REST query interface for data integration and ad-hoc reporting by technical users or ``accidental programmers``.

Creating Web APIs that are a joy to use
by Issac Kelly
Issac is an avid API consumer. He'll cover how to make an API that is not terrible. This is apparently very difficult to do, and many anti-patterns will be shown. No care will be taken to protect the guilty. This talk is not as focused on Python, as it is on creating Web APIs, and an understanding of HTTP is assumed.

Exchange Digital Money using Bitcoin
by Dave Steele
Bitcoin is described as the first decentralized digital currency. It uses a novel combination of public key encryption, proof-of-work based logging, and peer-to-peer technology to create a type of money which can be transferred over the Internet. While the currency has experienced a recent surge in popularity, there remain significant opportunities to improve the core applications for casual users. This talk describes how Bitcoin works, explains how to use Python to interface with existing tools, and explores opportunities for Python to improve the Bitcoin ecosystem.
