Nothing makes or breaks our teams like the members they hire. And so we rate and quiz, assign homework and whiteboard algorithms until candidates are blue in the face. But does it work? In this session, we’ll unpack common interviews and how they stack up with research into predicting performance. We’ll learn to design interviews that work, what kinds don’t work at all, and how to tell the difference, with science!

So you've just graduated from a bootcamp and you're starting your first real job in software development. You've got several Rails apps under your belt and you're excited to get started. But few jobs offer the opportunity to build new apps; it's much more likely that you will be part of a team charged with maintaining and growing a legacy application. How can you get started working on an aging codebase when the sum of your experience so far was with greenfield apps?

Before a request ever hits your Rails application, it winds its way through a series of pieces of Rack middleware. Middleware sets session cookies, writes your logs, and enables the functionality in many gems such as Warden.

With Rails or any Rack app, you can easily insert your own custom middleware, allowing you to log, track, redirect, and alter the incoming request before it hits your application.

You will leave this talk confident in writing your own custom middleware, better able to troubleshoot gems that rely on middleware and with an understanding of how your Rails app functions.

Your existing message system is great, until it gets overloaded. Then what? That's when you should try Kafka.

Kafka's designed to be resilient. It takes the stress out of moving from a Rails monolith into a scalable system of microservices. Since you can capture every event that happens in your app, it's great for logging. You can even use Kafka's distributed, ordered log to simulate production load in your staging environment.

Come and learn about Kafka, where it fits in your Rails app, and how to make it do the things that message queues simply can't.

Being a Rails developer is more than just understanding how to use the Framework to develop applications.

To become an efficient developer, you should learn how the Framework works; how deep this understanding should be is up to you. Exploring the Framework code is something that everyone should do at least once.

Not only may you learn how it works but also, you might learn new tricks from the code itself or discover small features that are not widely publicized.

Searching content across multiple database tables and columns doesn't have to suck. Thanks to Postgres, rolling your own search isn't difficult.

Following an actual feature evolution I worked on for a client, we will start with a search feature that queries a single column with LIKE and build up to a SQL-heavy solution for finding results across multiple columns and tables using database views.

We will look at optimizing the query time and why this could be a better solution over introducing extra dependencies which clutter your code and need to be stubbed in tests.

You might think that hiring interns is charity work. Your company is bringing on less-than-baked engineers and spending precious engineering resources to train them and bring them up to speed on your technologies.

Surprise! Interns actually help your team, too. Running a successful internship program helps your team level up its teaching skills, discourages silos, and encourages writing maintainable code. I’ll talk about mistakes, successes, and specific processes to keep your team and interns productive, and you’ll leave this talk with plenty of fodder for hiring interns at your company.

Shopify is one of the largest Rails apps in the world and yet remains to be massively scalable and reliable. The platform is able to manage large spikes in traffic that accompany events such as new product releases, holiday shopping seasons and flash sales, and has been benchmarked to process over 25,000 requests per second, all while powering more than 243,000 businesses. Even at such a large scale, all our developers still get to push to master and deploy Shopify in 3 minutes. Let's break down everything that can happen when deploying Shopify or any really big Rails app.

ActiveJob made a huge impact when it landed Rails 4.2. Most job processors support it and many developers use it. But few ever need to dig into the internals. How exactly does ActiveJob allow us to execute performant, thread-safe, asynchronous jobs in a language not known for concurrency? This talk will answer that question. We'll build our own asynchronous job processor from scratch and along the way we'll take a deep dive into queues, job serialization, scheduled tasks, and Ruby's memory model.

Rails ships as a number of components, Active Record, Active Support, ..., largely independent of each other, but somehow something orchestrates them and presents a unified view of the system.

Then we have config/boot.rb, config/application.rb... what do they do? Application initializers, environment configuration, what runs when?

Understanding how that works becomes an inflection point in any Rails programmer that goes through it. You go from that cloudy idea of an initialization that sets things up for a certain definition of "things", to a well-understood process.

Nowadays, we often rely on third party services that we integrate into our product, instead of building every aspect of an application. In many cases, well written API clients exist, but on occasion you run into the issue that there isn't a ready to use client or it simply doesn't fit your needs. How do you write a good API client and more importantly how do you test it without hitting the remote API. So far, the standard approach has been replaying requests with VCR or stubbing them with Webmock. There is a third option: simulating foreign APIs with Sinatra from within your test suite!

ActiveRecord is a great tool, but knowing SQL can help you to build better, faster applications and quickly find answers to common business questions. In this talk you'll see an overview of basic-to-intermediate SQL techniques that you can use to: learn about unfamiliar data sets, identify and resolve slow query problems, quickly build ad-hoc reports, combine multiple tables and perform calculations.

Specifically targeted to the Junior Rails Developer, we will explore with non-trivial yet approachable examples and see how learning SQL can help you become a better software developer.

In 2015, nearly a hundred programming boot camps produced thousands of graduates in North America alone. While boot camps help address a need for professional software developers, their graduates have different skill sets and require different interview assessment and career management than fresh college graduates with degrees in computer science. In this talk, we'll look at how boot camps prepare their students, how to interview graduates, and how to help them continually learn during their careers, developing a holistic model for hiring and growing boot camp graduates in the process.

Adopting Rails and Ruby for use within a large development organization was and continues to be an adventure. Rails and Ruby have been in use at Cerner for 7 years and over that time, their use has gone from niche technology used by a handful of people to a core platform used by hundreds. Along this adventure, we have learned many lessons and gained lots of experience. In this talk, we’ll share the interesting up and downs of this adventure in an effort to share our experiences and knowledge.

Just like there’s an app for that, there’s an API for that! But not all APIs are created equal, and some APIs are harder to work with than others. In this talk, I will walk through some common gotchas developers encounter when consuming a 3rd party API. I will explain why it’s important to familiarize yourself with the API you’re consuming prior to coding, as well as share tools to help you get acquainted with an API much faster. Lastly, I will go over debugging and testing the API you’re consuming, because testing is not just for the provider of the API!

Ever felt jealous of "other" Ruby web frameworks whose applications can be run from a single file? Did you know Rails can do this too?

Starting from a fresh "rails new" install, we'll gradually delete and pare away to find the beautiful, light, modular and object-oriented web framework underneath. Eventually we'll end up with a tweet-size Rails application! We'll learn about Rails' initialization process and default "stack", and investigate the bare-bones required to get a Rails app up and running.

Ever hire someone from a traditional IT organization who seemed like a great person, only to have them end up a sucking pit of negativity that had to be fired? Traditional IT can be an incredibly hostile environment, leading to survival strategies that aren’t always compatible with small agile-based teams. In this session, I will show how these survival strategies came to be, and ways to deprogram them to reduce your recruiting churn. Better yet, the tools to do so are already in agile.

Matz declared that the next major version of Ruby is going to be 3x faster than Ruby 2. But how can we make a software 3x faster? Can we do that for Rails?

In this session, we will discuss the ways to survey performance hotspots in each layer of the framework, tuning techniques on the performance issues, and some actual works that you can apply to your apps.

Topics to be covered:

Speeding up DB queries and model initialization
View rendering and template lookup
Routes and URLs
Object allocations and GC pressure
Faster Rails boot and testing

How can you tell a story using only email, a laser printer, voicemail? Last year I created an immersive experience for one audience member in a standard office cubicle. The piece used a rails app and some other custom software and no live actors to tell a story about office culture. This talk focuses on the techniques of digital storytelling, my process of developing the story as I wrote the code, and the strategies I used to create an emotional connection with a user. If you are interested in the intersection between stories, software, game design and narrative design, this talk is for you!

They bridge your application and your database. They're object-relational mappers, and no two are alike. Join us as we compare ActiveRecord from Rails with Ecto from Phoenix, a web framework for Elixir. Comparing the same app implemented in both, we'll see why even with two different web frameworks in two different programming languages, it's the differing ORM designs that most affect the result. This tale of compromises and tradeoffs, where no abstraction is perfect, will teach you how to pick the right ORM for your next project, and how to make the best of the one you already use.

It's impossible to iterate quickly on a product without a reliable, responsive CI system. At a certain point, traditional CI providers don't cut it. Last summer, Shopify outgrew its CI solution and was plagued by 20 minute build times, flakiness, and waning trust from developers in CI statuses.

Now our new CI builds Shopify in under 5 minutes, 700 times a day, spinning up 30,000 docker containers in the process. This talk will cover the architectural decisions we made and the hard lessons we learned so you can design a similar build system to solve your own needs.

Assertions (or expectations) are the most important part of any test framework. How are they written? What happens when one fails? How does a test communicate its results? Past talks have shown how test frameworks work from the very top: how they find, load, select, and run tests. Instead of reading code from the top, we’ll write code from scratch starting with assertions and building up a full test framework. By the end, you'll know how every square inch of your testing framework works.

In this talk we will look at recent efforts to revive Sprockets, and make it more maintainable. We will look into how your projects can be structured to avoid burnout and survive a change of maintainers. Let's save Sprockets.

This talk is for anyone who's had to promise new features to a client when they weren't actually sure how they'd deliver on the promise.

We all have big visions and big ideas, but our teams and abilities are finite resources. We'll talk about how to manage expectations, growth, technical debt and delivery (and still be able to sleep at night despite that last wonky commit). We'll talk about the never-ending product roadmap, product reality and how what we create falls somewhere in between.

Testing Rails 5 apps has become a better experience out of the box. Rails has also become smarter by introducing the test runner. Now we can't complain about not being able to run a single test or not getting coloured output. A lot of effort has gone into making tests -- especially integration tests -- run faster.

Come and join me as we commence the journey to uncover the secrets of testing Rails 5 apps.

Hindsight is 20/20, and there's a lot of advice out there telling you to do what the author wishes they had done at their last company to avoid disaster. Let's try to follow their advice and see where it lands us.

We'll take four journeys from rails new into a reasonable future. The first three, “dedicated team pulling apart the monolith a year later than hoped”, "nothin' beats a monolith", "services from day one" will blow up the Enterprise, while the fourth, “take reasonable steps to let the system evolve”, won't.

When you look at your response times, satisfied that they are "fast enough", you're forgetting an important thing: your users are on the other side of a network connection, and their browser has to process and render the data that you sent so quickly. This talk examines some often overlooked parts of web applications that can destroy your user experience even when your response times seem fantastic. We'll talk about networks, routing, client and server-side VMs, and how to measure and mitigate their issues.

Compose is committed to making remote work work. Our biggest hurdle is communication and teamwork. When we joined forces with IBM, we added a new issue - how to scale. So, our devs built an app we’re open-sourcing called Fizz. Built on Rails, Fizz helps us empower our team to do great work, feel like family, and operate happily and efficiently as an international, remote, self-managing organization. We work transparently, commit to open-source, wear sweatpants, and genuinely enjoy each other and we’re committed to keeping it that way. We harnessed the power of Rails to make that happen.

Although bundle exec rake db:migrate is probably the single biggest killer feature in Rails, there is a lot more to rake.

Rails offers several rake tasks to help with everyday project management, like redoing a migration because you changed your mind on one of the columns, clearing your log files because they get so big, and listing out the TODOs and FIXMEs.

What's even more awesome that all that is that you can create your own rake tasks. Got a tedious command-line process? Write a rake task for it!

Aaron was born and raised on the mean streets of Salt Lake City. His only hope for survival was to join the local gang of undercover street ballet performers known as the Tender Tights. As a Tender Tights member, Aaron learned to perfect the technique of self-defense pirouettes so that nobody, not even the Parkour Posse could catch him. Between vicious street dance-offs, Aaron taught himself to program. He learned to combine the art of street ballet with the craft of software engineering. Using these unique skills, he was able to leave his life on the streets and become a professional software engineer. He is currently Pirouetting through Processes, and Couruing through code for GitHub. Sometimes he thinks back fondly on his life in the Tender Tights, but then he remembers that it is better to have Tender Loved and Lost than to never have Tender Taught at all.

Unit testing is mostly a solved problem, but how do you write tests for the visual side of your app—the part that your users actually see and interact with? How do you stop visual bugs from reaching your users?

We will dive deep into visual regression testing, a fast-growing technique for testing apps pixel-by-pixel. We will integrate perceptual diffs in Rails feature specs, and learn how to visually test even complex UI states. We will show tools and techniques for continuous visual integration on every commit, and learn how to introduce team visual reviews right alongside code reviews.

Your team has been tasked with releasing new and better versions of your product at record speed. But the risk of moving quickly is things break in production and users abandon your buggy app. To stay competitive, you can't just ship fast - you also have to solve for quality.

We'll rethink what it means to actively monitor your application in production so your team can ship fast with confidence. With the right tooling, workflow, and organizational structures, you don't have to sacrifice release times or stability. When things break, you'll be able to fix errors before they impact your users.

Two years ago we started a major redesign of our REST API with the goal to decouple it from our main Rails application and expose all the main features via API. It was not a trivial task, but still feasible due to the guidelines we adopted in the last 6 years to structure our Rails application.

Application view layers are always hard to manage. Usually we handwave this as the natural consequence of views being where fuzzy user experience and designer brains meet the cleaner, neater logic of computers and developers. But that handwave can be misleading. View layers are hard to manage because they’re the part of a system where gaps in a team’s interdisciplinary collaboration become glaring. A comprehensive, well-documented styleguide and component library is a utopian ideal. Is it possible to actually get there? It is, and we can do it incrementally with minimal refactor hell.

GitLab, the open source alternative to GitHub written in Rails, does not scale automatically out of the box, as it stores its git repositories on a single filesystem, making storage capabilities hard to expand. Rather than attaching a NAS server, we decided to use a cloud-based object storage (such as S3) to replace the FS. This introduced changes to both the Ruby layer and the deeper C layers. In this talk, we will show the audience how we did the change and overcame the performance loss introduced by network I/O. We will also show how we achieved high-availability after the changes.GitLab, the open source alternative to GitHub written in Rails, does not scale automatically out of the box, as it stores its git repositories on a single filesystem, making storage capabilities hard to expand.

Most code is a mess. Most new requirements change existing code. Ergo, much our work involves altering imperfect code.

That's the bad news.

The good news is that every big mess consists of many small ones. Certain small problems occur so frequently that they've been given names, and are collectively known as "Code Smells".

This talk shows how to take a pile of perplexing code, identify the "smells", and surgically apply the curative refactorings. It breaks a messy problem into clear-cut pieces, and proves that you can fix anything without being forced to understand everything.

The client/server architecture that powers much of the web is evolving. Full stack, monolithic, apps are becoming a thing of the past as new requirements have forced us to think differently about how we build apps. New client/server architectures create a clear separation of concerns between the server and the client.

As developers, we have the ability to create the new abstractions that will power the web. Understanding the past, present, and future of the client/server help us to become more active participants in the future ecosystem for building web applications.
