An IRC Connection: Implementation and Bot
(30 Minutes)
By: Aaron Brady
Slides Link
IRC is a protocol for text exchanges with multiple recipients with publish/subscribe capabilities. A basic program that interacts with an IRC server is easy to make, but becomes more difficult with additional functionality. The task involves a few domains: sockets, parsing, and a multi-way mapping object for the state. We take a look at 4 custom modules to get it done: Multi-connection dispatch, Raw to dict, Connection model, and Relation; plus one for "main" for the bot itself.

There were 986 roadway fatalities in Illinois in 2013. Where's the data?
(20 Minutes)
By: Nick Bennett

Seen on garish LED roadway signs all around Chicago on New Year's Eve, 2013: 986 TRAFFIC DEATHS IN 2013. It leads to many questions: On what roads? When did the accidents happen? What do we do now? I'm scared to drive. I will talk about purging my fears by finding the data to answer some of those questions. http://tothebeat.github.io/fatal-car-crashes/ This talk will involve PythonAnywhere, IPython, a module that's not even on PyPi (dbfpy), searching for and finding open government data, CartoDB, Google Fusion Tables, csv, and maybe Pandas. Rest assured, there will be no graphic photos.
