Cooking track

How did you get something to work? Show us how to write the script, configure the utility, debug the code. Share your best recipes.
From the beginner to the advanced level, we’re looking for tips, tutorials, best practices, and collaborative development sessions. Share what you know about your favorite tools, programming languages, and development techniques. Example topics from the past include “Data Science in the Open” and “Hands-on Virtualization with Ganeti.”

* Build your own exobrain

Online services like "If This Then That" (IFTTT) are great for automating your life. However they provide limited ways for the end-user to add their own services, and often require credentials that one may normally wish to keep secret. The 'exobrain' project allows for service integration and extension on a machine *you* control.

* Confessions of a DBA: worst and best things I've done in production

In the past 15 years, I've done some pretty horrendous things around the M in LAMP. I will balance this with good things I've done too.

* Data Wrangling: Getting Started Working with Data for Visualizations

Good data visualization allows us to leverage the incredible pattern-recognition abilities of the human brain to answer questions we care about. But how do you make a good visualization? Here's a crash course.

* Don't Let Your Tests Flake Out

The build's red with a test failure. You re-run the tests and suddenly all is well. What's going on?
Jason Clark

* Know Thy Neighbor: Scikit and the K-Nearest Neighbor Algorithm

This presentation will give a brief overview of machine learning, the k-nearest neighbor algorithm and Scikit-learn. Sometimes developers need to make decisions, even when they don't have all of the required information. Machine learning attempts to solve this problem by using known data (a training data sample) to make predictions about the unknown. For example, usually a user doesn't tell Amazon explicitly what type of book they want to read, but based on the user's purchasing history, and the user's demographic, Amazon is able to induce what the user might like to read.

* Lightning Talk Workshop

Heard of lightning talks but never considered giving one? Never fear, lightning talks are easy! During this session, you'll write and practice your first lightning talk.

* Modern Home Automation

There are a few different options available to you to control your home automation system. Many manufacturers make it convenient to use their system by not only making a convenient to install their products and use their interface, but will actually host all the software portions for you. Many provide apps for your IOS or Android device and have web interfaces for your laptop as well, making the control of these devices very streamlined and simple, especially if there are many devices to be managed. Other more DIY-approach solutions also have interfaces to control your automation, although require a bit more setup. For example, with the power strip in the previous example, you first need to connect it to your wireless network, and then you'll be able to use the supplied phone/tablet app to toggle the ports on/off. As with anything DIY: The sky's the limit, although it requires more technical understanding of what's going on.

* My Journey into Open Source Design

Becoming a contributing designer on an open source project is often tougher than contributing code. The pathways to designing for open source projects are often unclear.

Mel Choyce

* Network Science for Fun and Profit

Understanding the relationships between data elements has become increasingly valuable, as LinkedIn, Facebook and Google illustrate. Network science provides a means to understand, explain, predict and otherwise utilize these relationships. I will provide a brief overview of network science, with examples and illustrations using R, focused on providing an entry point to their use for fun and profit.

* xmonad: the window manager that (practically) reads your mind

Many desktop environments try to be easy to use for the average user, but that's not you. You're at your computer all day writing code; you don't have time to waste _dragging windows_ (ugh!) or watching _animated transitions_ (yuck!). David Brewer will demonstrate how by using xmonad, a tiling window manager, you can bend your desktop to your will and control your windows with telepathy. Kind of.

Alchemy.js makes it easier for anyone to create data visualizations that represent these types of data - without being a data visualization expert.

* Rethinking the Single Page Web Application

We were promised a glorious future with RESTful APIs, clients with lighting fast JavaScript engines, and an end to sending UI from the server. Now your project is late, the technical debt is piling up, and you're thinking that hey, Rails wasn't awful. Let's talk about when it's a good idea to build a single page, client side app, and when it's not. I'll be drawing from my experience building a single-app to manage an enterprise software as a service product. Before you jumped into Backbone, Ember, or Angular, you needed to think through the APIs you have, and still had to build. You need to look at the interactions in your UI. You need to figure out where and how your users will access the application.
