* Exploring Mental Illness With Open Source

Julia Nguyen leads if me, an app to share mental health experiences with loved ones. In doing so, she has explored her insecurities with mental illness, learned how to engage diverse contributors, and developed better software practices with Ruby on Rails and JavaScript. She’ll share the lessons she has learned from transforming a passion project into an open source project. Inclusion takes on many forms in an open source project, including supporting contributors from all types of backgrounds, being empathetic to their project goals, and trusting them to take lead. As a mental health project, if me must also accommodate its contributors who face their own mental health challenges. All open source projects should do the same. Managing people is just as important as managing technical contributions in software.
Julia Nguyen

* Free Culture in an Expensive World

Money is a common worry, inside the open source community and out, but we often feel uncomfortable discussing it. We’ll talk about why that is and how our social norms around money impact who participates in open source and how they do so. The heart of this talk will be a series of case studies based on interviews with community members covering various economic models for open source, including worker co-ops, grant-funded and academic projects, for-profit business models, crowdfunding campaigns, and all-volunteer projects. We’ll explore the sustainability of each model as well as how they deal with the social pressures outlined in the first part of the talk.

* Free Everything: Hacking Content Liberation

Large commercial websites rely on the "network effect" to keep users from exploring alternatives. Putting contributions under an open license can break this effect. This talk will explore hacks to give users control over the content they contribute to commercial websites.
Erik Moeller

* Graph Databases WIll Change Your Freakin Life

Most developer have worked with relational DBs like MySQL or PostgreSQL, but for many use cases they aren't the best option. Graph databases have a simpler, more powerful model for handling complex related data. In this talk we'll work with Neo4j to explore the advantages of graph DBs. Attendees will learn the graph model, how graph DBs let you do things that are practically impossible with SQL, and the best options for integrating one into your application -- new or existing.

* Let’s build a CI/CD pipeline

An exploration of the cost and value of CI/CD, and a walkthrough of setting up a CI/CD pipeline.
Jean de Klerk

* Little Leaks Sink Your Tests

"The tests pass on my machine." "Wait, it was working a minute ago." "Oh, that test is flaky sometimes." Unpredictable tests are toxic for our productivity. They undermine confidence in our code. They encourage us to wallpaper over the immediate problem, rather than fixing the underlying cause. In this presentation, we'll talk about a chief cause of flaky tests: leaky global state.
Ian Dees

* Micro-services provide some benefits, but at what cost?

Several years ago, there was an architectural paradigm shift toward "micro-services" and away from the "monolithic" application stack. A micro-service architecture comes with scalability and replaceability, among others, but is it worth the time and effort to build it? Is it worth debugging API calls gone wrong? If you're thinking about making this move, have already started, or have already deployed to production, this is an ideal venue to see what others are doing with micro-services.
Serge Domkowski

* Monitoring Asynchronous Applications

The lure of asynchronous programming is that it will make your application run faster and your code simpler to reason about. So we have our wonderfully efficient non-blocking app; how do we check that it's delivering the goods performance wise?
Amy Boyle

* Monoids, and Sketches, and CRDTs, oh my!

A (hopefully) accessible introduction to some of the key mathematical concepts that make distributed and streaming computation possible.
Kevin Scaldeferri

* Open sourced tools for Agent Based Modeling

Agent-based modeling is a technique used to explore both complexity and emergence by simulating individual actors and their actions inside of a system. Think of systems such as the traffic in the city or financial markets where one actor can have an effect on the decisions of others until the system’s direction changes its course. During this survey, you will gain an understanding of open source software available in a variety of languages and how to get started quickly.

* What can the open source software of today learn from the history of software documentation?

In the early years of easily distributable software, technical writers and the documentation that they produced were a crucial part of the software development process. Why? What kinds of contributions did they make, and what might their close cooperation with the programmers of their day teach us about how to manage open source projects better today?

* Consequences of an Insightful Algorithm

We have ethical responsibilities when coding. We're able to extract remarkably precise intuitions about an individual. But do we have a right to know what they didn't consent to share, even when they willingly shared the data that leads us there? How do we mitigate against unintended outcomes? In this talk, we'll learn how to build in systematic empathy, integrate practices for examining how our code might harm individuals, and net consequences that can be better for everyone.
Carina C. Zona

* Good Enough Voter Verification & Other Identity Architecture Schemes for Online Communities

This talk is a deep dive into considerations for Identity Architecture for online communities. It's most specifically applications for political action, civic engagement, or virtual nations. I'll talk about pragmatic solutions for voter verification using the state voter registration database, schemes for peer to peer authentication, offline/online identification, Impartial Identity Architecture to control conflict, and more. The discussion is high level and appropriate for beginners, but there will be links to code and big ideas.

People from marginalized communities struggle to break into tech, clawing our way through a racist, sexist, classist, ableist system only to be fired, quit or just suffer in misery. I’ll explore what it really takes to create a workplace that is truly welcoming of everyone.
Kronda Adair

* Troubleshooting In Distributed Systems

The shift to microservice and distributed architectures has made software products more flexible and scalable-- and a lot more complex. With so many moving parts, ephemeral conditions and the spectre of partial failure, it can be much more difficult to pinpoint how and why things break. Learn how Logstash, Elasticsearch and Kibana can be used to monitor healthy systems and investigate issues as they pop up, and what we can do outside of software to improve our process of problem-solving.

* !done - Hacking IRC Bots for Distributed Teams

When our company was acquired we needed a way to see everything that was done each day all in one place. Teams were using different methods to do this: standups, written reports, emails and meetings. Nothing stuck. Done reports introduces a simple IRC command: !done. Team members say !done and what they just did. These !dones are put into a daily report. !done becomes a part of everyday at work, not a strained task that’s easily forgotten.

* Citizenship Online: Open Source Politics

Online deliberation refers to applications which help communities make decisions. This varies from Exploratory deliberation, like Amazon reviews, where an individual makes a decision by consulting their community, to very structured Decision Making deliberations where a community needs to forge a single legally and logically defensible decision.

Adron Hall

* Expanding Your Empathy

I believe empathy is the core competency that is missing from much of the efforts to push the tech community in a direction towards more diversity of all kinds. Companies, communities and conferences cannot expect everything to magically change until they're willing to go deep and examine the systemic patterns and structures that keep underrepresented communities from feeling safe and welcome in the tech space.
Kronda Adair

* How My Kids Are Learning to Program By Talking

My children have patiently tolerated a number of teach-STEM-quick schemes their dad has brought home. They've taught robots to dance, created simple animations using Scratch, and, quite frankly, made a lot of poop jokes. What's missing from these programming tools was storytelling. The ones we tried focused either on easy interactivity or expressive power. If only there were a way to combine the two... oh, wait, there was—46 years ago!

Howard Abrams

* Morning Keynote: Ashe Dryden

It's been scientifically proven that more diverse communities and workplaces create better products and the solutions to difficult problems are more complete and diverse themselves. Companies are struggling to find adequate talent. So why do we see so few women, people of color, and LGBTQ people at our events and on the about pages of our websites? Even more curiously, why do 60% of women leave the tech industry within 10 years? Why are fewer women choosing to pursue computer science and related degrees than ever before? Why have stories of active discouragement, dismissal, harassment, or worse become regular news?

* Open Sourcing Depression

In the spirit of open source, I'd like to shine a spotlight on depression. Not because it's easy, but because it's important. Mental illness affects many of us, but the stigma attached to it dissuades most people from talking about it openly. That's not how we make progress. With this talk, I want to do my part.

Conventional wisdom says that writing high-performance code means working without the safety net of credible compile-time safety checks. Mozilla Research (a community of researchers, engineers, and volunteers) is trying to prove that conventional wisdom wrong by building Rust, a new systems programming language. Rust takes advantage of well-understood programming language technology to combine aggressive compile-time error checking with the high degree of direct control over the machine necessary to write efficient systems programs. By way of examples, I'll teach you how to use Rust to write fast and trustworthy code.

* Where "Small is Beautiful" meets "Big Data"- Empowering Local Communities with Open Hardware

"The future is already here — it's just not very evenly distributed" - Author William Gibson Whether rightly or wrongly so, it has been argued that the "information revolution' has resulted in a wider gap between those with skills and access to digital resources and those who do not. The same can apply to entire communities where language, geography and cultural barriers have created a new world of "Have Nots". The growing civic hacker movement is making long strides towards eliminating the "silicon ceiling" effect, but thanks to the emerging practice of "open hardware" the "civic hacker" is joined by a new class known as the "maker"... The civic hacker is capable of great things, and already has enough of a track record to be proud of. But the hacker ultimately is, and should remain, part of a vanguard elite who like the Bletchley Park codebreakers of WWII possess skills of such value that the work of a single individual can have a direct impact on the outcome of a war (or election...) The "Maker" on the other hand represents a fundamental break from a passive society of consumers into something more closely resembling the small-scale producers and artisans on which the U.S was based on.

* "Why did you do that?" You're more automated than you think.

Your brain is really good at surviving in neolithic Africa, but not because of our powers of higher levels of thought; they're much too slow. Humans are so successful as a species because we're champions at automating things, including our own thoughts and behaviours.
