Tavis RuddTwo years ago I developed a case of Emacs Pinkie (RSI) so severe my hands went numb and I could no longer type or work. Desperate, I tried voice recognition. At first programming with it was painfully slow but, as I couldn't type, I persevered. After several months of vocab tweaking and duct-tape coding in Python and Emacs Lisp, I had a system that enabled me to code faster and more efficiently by voice than I ever had by hand. In a fast-paced live demo, I will create a small system using Python, plus a few other languages for good measure, and deploy it without touching the keyboard. The demo gods will make a scheduled appearance. I hope to convince you that voice recognition is no longer a crutch for the disabled or limited to plain prose. It's now a highly effective tool that could benefit all programmers.

Ashwin Panchapakesan Genetic algorithms are a class of evolutionary algorithms, which have been around since the mid 1950s. Since then, a lot of study has been done on these algorithms, using them to solve various different types of problems. While m

Sean Zicari I find it very handy to be able to fire up the command line and make changes through a well-designed CLI tool. I'd like to show how the 3rd party urwid library or the built-in curses library can be used to build such tools easily.

Larry Hastings Ever wondered how CPython actually works internally? This talk will show you. We start with a simple Python program, then slowly step through CPython, showing in exhaustive detail what happens when it runs that program. Along the wa

Brandon Rhodes Why did I start using Python in the late 1990s? Was it for any of the reasons that I remain a fan today? In this talk we will explore how Python, even while training us to avoid and become blind to its rough edges, works to teach us ne

Nathan Taggart Before you dive into a machine learning project, learn from the mistakes that I made while building a prediction engine for betting on horse races. In this introductory talk, learn about common data science tasks like data munging, pre-processing, classification, regression, and interpreting results.

Brandon Rhodes While Java and C use static type declarations to eliminate ambiguity, the Python programmer must survive through sheer clarity and consistency in naming variables. We will explore the deep unspoken conventions that the Python comm

Alex Martelli Our culture's default assumption is that everybody should always be striving for perfection -- settling for anything less is seen as a regrettable compromise. This is wrong in most software development situations: focus instead on keep

A. Jesse Jiryu Davis Python 3's new “asyncio” module is an efficient async framework similar to Node. But unlike Node, it emphasizes a modern idiom called coroutines instead of callbacks. Coroutines promise the best of two worlds: the efficiency of callbacks, with a natural and robust coding style similar to synchronous programming. I’ll explain how asyncio’s coroutines work, and show how they are built using Python generators, the “yield from” statement, and the Future and Task classes. You will gain a deep understanding of this miraculous new programming idiom in the Python standard library.

Riona MacNamara Last year, we were inspired to action by a presentation at Write the Docs. This talk will tell the story of what happened next: how, in two quarters, we worked with a small self-forming team of amazing writers and engineers to build a platform in six months is well on the way to becoming a part of the standard Google engineering workflow. We’ll share how that platform transformed our role as technical writers and our relationship with engineering. We’ll cover design and implementation details, but we’ll also talk about our experience - how we learned that being audacious (but not reckless), focused (but open and generous), and unafraid could revitalize our whole approach to work and save us from burnout. We& 39;ll talk about our ever-growing appetite for disruption: How it changed beyond recognition our relationships with engineers, fellow writers, and senior leadership, making us fall in love again with our roles as documentarians.

Sean Cribbs Sean Cribbs teaches us how to read and implement research papers - and translate what they describe into code. He covers examples of research implementations he's been involved in and the relationships he's built with researchers in the process.
