    The idea that confidence is solely the result of positive self-talk is circular: If I believed in my ability to talk myself up, I would. But if I did, I wouldn't need to talk myself up. It's not as simple as having faith.

    There's a thread amongst all peak performers and skilled practitioners: specific habits, routines, and processes that wrap uncertainty and create confidence. Oscar-winning actors rehearse, pro-drivers do laps, chefs prep.

    This talk will help you recognize and design habits, routines, and practices that embed confidence into the body.

    Individuals can only advance when they know they are valued, listened to, and understood. Without having lived the same life as them, it's often hard to understand why people do what they do. It requires empathy, and practicing empathy can be tough when someone differs greatly from you, personally or professionally. But, being empathetic can be learned, for instance through method acting.

    Let's talk about the fascinating acting techniques of Stanislavski, Strasberg, Adler & Meisner, and learn how you too can employ the Method to better understand (and work with) the people in your life.

    In any production rails application’s simplest form, there is one version of the app deployed to a single host or cloud provider of your choice, but what if there were laws and regulations in place that required your application to be replicated and maintained within the geographical boundaries of other countries. This is a requirement of countries that have data sovereignty laws and a regular hurdle to overcome when dealing with sensitive data such as protected health information. This talk provides a case study of how we devised an automatic deployment strategy to deploy to multiple countries.

    Have you written JSON APIs in Rails a few times? Even if you’re escaped implementing a “render: :json” call, some day soon you’ll need to get JSON data out to a native client or your front-end framework. Your Rails apps might change, but the pitfalls for JSON APIs stay the same: They’re hard to discover, difficult to change from the client side, and documenting them is a pain. For your next app, or your current one, let’s consider GraphQL. I'll show you how to implement it in your app and offer real-world advice from making it work in an existing Rails app.

    Tracking down bugs can be hard. Tracking down bugs in a codebase touched by 5000 people is even harder. Making heads or tails of an inheritance-happy codebase like Rails can be a nightmare. How do you find where the bug in save is when save is overridden by 15 different modules?!

    In this talk, we'll look at the process that goes into fixing a bug in Rails itself. You'll learn about every step from the initial report to when the fix is eventually committed. You'll learn how to navigate Rails' internals, and how to find the source of the problem -- even if you've never committed to Rails.

    Star Wars fans may have been excited about 2016’s release of Rogue One because of the courageous new rebel characters it introduced, but it also provided a lot more insight into the Empire's Corp of Engineers and how they ended up building the Death Star. As developers, we have a responsibility to think about the ethical implications of our work and how it might be used. This session will discuss ways of deciding for yourself what kinds of projects you are or aren't comfortable working and tips for self-accountability in your career - through the lens of characters we know and love from Star Wars.

    Rails brings us a lot of useful tools out-of-the-box, but there are missing parts too. For example, for such essential tasks as authorization we are on our own. Even if we choose a trending OSS solution, we still have to care about the way to keep our code maintainable, efficient, and, of course, bug-less. Working on Rails projects, I've noticed some common patterns in designing access systems as well as useful code techniques I'd like to share with you in this talk.

    A good test suite can help you catch errors in development, but how do you know if your code starts misbehaving in production?

    In this talk, we’ll learn about checkups: a powerful and flexible way to ensure that your code continues to work as intended after you deploy. Through real-world examples, we’ll see how adding a simple suite of checkups to your app can help you detect unforeseen issues, including tricky problems like race conditions and data corruption. We’ll even look at how checkups can mitigate much larger disasters in real-time. Come give your app’s health a boost!

    In the late 1700s the discovery of the principle of interchangeable parts shifted the demand for the expertise of artisans from production to design and invention. This shift transformed Western civilization and opened the way for the industrial revolution. We face a similar opportunity now as one generation of software developers reaches its professional peak and a new wave of developers enter the field. This talk will trace the historical evolution of the artisan and explore how understanding this history can help us to maximize and multiply the impact of senior software developers.

    Booleans are pretty simple — they're either true or false. But that doesn't mean that they're always easy to use, or that they're always the right choice when they appear to be the obvious choice.

    We'll cover several anti-patterns in the use of booleans. We'll discuss why they're problematic, and explore some better alternatives.

    Last summer, two high school juniors with very little coding experience joined Vitals as software engineering interns. Over the course of six weeks, they attempted to level up their programming skills while also learning the Vitals domain. They struggled through obstacles and experienced thrilling code highs, and ultimately emerged as more confident developers.

    Using their story as a guide, this talk will explore practical ways of structuring mentoring and onboarding processes. Whether your next hires are newbies or seasoned pros, you’ll walk away with strategies to help them code confidently.

    Devly, a multi-service development environment
    Writing a system alone is hard. Building many systems with many people is harder.

    As our company has grown, we tried many approaches to user-friendly, shared development environments and learned what works and what doesn't. We incorporated what we learned into a tool called devly. Devly is used to develop products at Fastly that span many services written in different languages.

    We learned that the design of our tools must be guided by how teams work and communicate. To respond to these needs, Devly allows self-service, control, and safety so that developers can focus on their work.

    Being a mom is awesome! You finally get to be the one to post a million cute pictures of your adorable baby. It is also one of most challenging and hard things a woman can go through, especially if they're in software.

    In this talk you'll hear stories from women in the programming community, struggles they have gone through, and why many of them left their jobs after or during maternity leave (including me). If you want to help your mom friends stick around and feel included, or if you are from a company who wants to support the growth of your mom employees, then this talk is for you.

    Moving from operations powered by scripts like Capistrano to containers orchestrated by Kubernetes requires a shift in practices. We'll talk about things beyond "Getting started with Kubernetes" guides, and cover such aspects of operations as gradual deployments, capacity planning, job workers and their safety, and how cloud environments like Kubernetes drastically change how we solve them.

    This presentation is about the lessons we learned while migrating hundreds of Rails apps within the organization to Kubernetes.

    Minitest 5 ships with ruby and is the standard test framework for rails. It already provides a traditional unit test framework, spec DSL, mocks, stubs, test randomization, parallelization, machine agnostic benchmarking, and tons of assertions all in under 2kloc. So what would Minitest 6 do differently? Hopefully to the end user, not much will change, and yet it will be worlds apart from Minitest 5. Come see how you can massively speed up your rails test runs and improve your testing practices by upgrading your test framework.

    Webpack integration landed in Rails 5.1 to a bit of excitement and confusion. On one hand, folks who had been using Javascript frameworks like Angular and React now have a clearer way to tie in their client-side application into the asset pipeline. Yet, why would we want to do this? What’s the purpose of adding Webpack to Rails, and what’s the advantage of utilizing it? How does this affect javascript frameworks that aren’t Webpack friendly? In this talk, we’ll explore these ideas as well as the future of client side integrations into Rails.

    Creating truly 100% accessible websites often requires specialized knowledge of the ins and outs of screen reader settings, browser defaults and HTML quirks, yet most of us still need to google how to turn on a screen reader. We attend "Web Accessibility 101" seminars and workshops over and over but very few of us end up with the kind of specialized knowledge necessary to make truly accessible websites. In this talk, we'll discuss why this is, and how we can eventually get to accessibility 102.

    Understanding indexes is key to demystifying database performance, and will have huge impact on one's ability to plan, contribute, and troubleshoot as one progresses in their career. Having said all that: many engineers still don’t really know what indexes ARE. Most simply know what indexes can DO. This presentation takes a look at the most commonly used index for any RDBMS: the B-tree. We will pull apart the data structure, discuss how it works, and briefly touch on some of the algorithms they use. With this baseline established, we will revisit a few common assumptions about indexes.

    One day I joined a team maintaining a huge, legacy, and slow Rails app. We thought that we have to optimize the application throughput for the user happiness, and so we formed a task force that focuses on the performance.

    Now, here's the record of the team's battle, including how we inspected and measured the app, how we found the bottlenecks, and how we tackled each real problem, about the following topics:

    Tuning Ruby processes
    Finding slow parts inside Rails, and significantly improving them
    Fixing existing slow libraries, or crafting ultimately performant alternatives

    When it comes to evaluating candidates for software engineering roles, it's hard to keep up with the latest and greatest techniques. We know logic puzzles don't work. Writing pseudocode on a white board is so tired and cliche at this point that companies brag about not doing that. Teams have resorted to what seems like an obvious choice at first blush: just have the candidate write some code. This new trend may have some unintended consequences, though.

    In this talk, you'll learn how to design an interview process which allows you to evaluate candidates without making them code for you.

    For many of us, APIs and their client libraries are the face of our applications to the world. We need to innovate with new features, but breaking changes are toxic to customer trust.

    In this session you will pick-up concrete design patterns that you can use and anti-patterns that you can recognize so that your service API or library can continue to grow without breaking the world. Using real APIs and open source libraries as a case study, we’ll look at actual examples of specific strategies that you can employ to keep your API backwards compatible without painting yourself into a corner.

    Rails is made possible by Ruby’s unique combination of deep dynamism and pragmatic elegance. In turn, Ruby inherited many of its core ideas from older languages including Lisp, Smalltalk, and Perl.

    In this talk, we’ll take a tour of these languages and their myriad influences on Ruby, to better understand the foundations of our tools, improve our ability to use them to their full potential, and imagine how they might be further improved.

    Authentication is one of the most common features of web applications, so it makes sense to have libraries that provide solutions for this problem. You've probably heard of or maybe used Devise: all you have to do is add it to your Gemfile and run a generator, and you have a robust authentication system.

    Behind the scenes, Devise uses Warden to handle authentication. In this talk, I'll explain what Warden is, why it's useful and how Devise takes advantage of it to build the most popular authentication gem for Rails.

    Does your git log output resemble an archaeological site from 500BC? Ransacked by Persians with some Spartan conflict? When we code and commit, our decisions, for better or worse, are preserved. As though in an archaeological record. Thanks to the archaeological record we can understand entire human cultures, but how much do we understand about the decisions developers are making today? Applying the same practices archaeologists utilise can help us understand the decisions developers are making in 2018.

    Rails is incredibly powerful because of its abstractions. For years, developers have been able to hit the ground running and be productive without having to know the in's and out's of the core computer science concepts that fuel this framework. But just because something is hidden away doesn't mean that it's not worth knowing! In this talk, we'll unpack the CS fundamentals that are used in the Rails router. Together, we'll demystify the graph data structure that lies under the hood of the router in order to understand how a simple structure allows for routing to actually work in a Rails app.

    Most Rails applications out there in the world deal with the manipulation and presentation of data. So the speed of our application is proportional to how fast we can work with data. Rails is good with presenting data. And our Database is the one who is good at processing data. But we sometimes make the mistake of just using the database as a file cabinet, and using ruby to process. The database is built for crunching data and returning to us the results that we need. This talk is about how to optimize your database so as to speed up your existing Rails application.

    Traditionally doing a full stack test of a Rails app with RSpec has been problematic. The browser wouldn't automate, capybara configuration would be a nightmare, and cleaning up your DB was difficult. In Rails 5.1 the new 'system test' type was added to address this. With modern RSpec and Rails, testing every part of your stack including Javascript from a browser is now a breeze.

    In this talk, you'll learn about the new system specs in RSpec, how to set them up, and what benefits they provide. If you want to improve your RSpec suite with full stack testing this talk is for you!

    How much JavaScript you include in your Rails application can feel like a choice between basically none or a full JavaScript single page application backed by a Rails API. When you have a team of people whose confidence with JavaScript is all over the place, this can feel like an impossible choice. Fortunately, there are many options in the middle that can allow those with less JavaScript confidence to stretch and grow while those with more confidence can build UI components with fewer constraints.

    Stop trying to be a computer; you're a human! You know what humans are good at? Storytelling. Stop trying to write tests just to get a green test suite, and start telling rich, descriptive stories. Once you have a good story, then you can worry about the implementation details (wait, is testing a form of abstraction and encapsulation?!). In this talk, we look at writing tests as simply telling stories to the test suite. By telling stories about the application (methods, controllers, features, &c.) the suite holds the storyteller accountable for making those stories become, and stay, true.
