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.
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.
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.
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 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.
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.
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.
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!
Legacy code is unpredictable and difficult to understand. Most of us will work with legacy code, so it’s important for us to understand its major pain points and their underlying causes. You’ ll come away from this talk with practical strategies to help you understand, improve, and even love legacy code.
A mixture of a talk on programming and a live classical music recital. Listen to a former-orchestral-clarinetist-turned-developer talk about parallelisms between music performance and programming - such as complexity, imposter syndrome, and true concentration - with live performances throughout!
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.
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.
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.
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.
Now that it has become a mature web development framework, Rails is no longer the exclusive realm of burgeoning startups. Healthy small and large businesses have grown with Rails for years. Shrinking and dying companies too. In this talk we'll look at how Rails and its ecosystem of libraries and services can support both newborn and aging apps, and when it struggles to do so.
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.
Despite general consensus that pairing is good, the desire to pair doesn’t come with instructions. Come to this talk to learn how to pair with someone more experienced, how (and why) to pair with your peers, and how to pair productively with someone less experienced. (Hint: productivity isn’t about the speed of new features.) Pairing is a fantastic tool for your professional toolbox: let’s design, refine, and refactor, together.
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.
OTCBTC, a cryptocurrency exchange founded in Oct 2017, was developed with Rails. It grows rapidly and has reached hundreds million of dollars of GMV and millions of pageviews within only two months after being launched.And quickly become the largest OTC exchange in Asia. Its ICO had successfully raised the amount equivalent to series B funding.
In this talk, Xdite will share how she and her team members struggled through the rapid growth of OTCBTC, the future opportunity in blockchain industry, and the challenge in developing such level of project.
This is a sponsored talk by OTCBTC.
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
Secrets are out. Credentials are in. This new Rails 5.2 feature offers a number of advantages over the old way of managing secrets. You get atomic deploys, you avoid putting sensitive data on environment variables, and your data is always encrypted.
This talk will reveal the secrets to success in using Credentials and EncryptedConfiguration, the API it uses internally.
This is a sponsored talk by Engine Yard.
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.
Throughout much of this conference you're going to hear people state obvious things. Sometimes, they'll even tell you that they think what they're saying is obvious. Why are they saying them at all, then?
It's obvious there must be more to the story, so let's examine what we mean by "obvious". You'll leave this talk encouraged and ready to apply what you've learned to better empathize with others. Through application, you'll see growth in both your professional and personal life.
Currently, our industry has a surplus of bright junior developers, but a lack of open junior positions. Building a developer apprenticeship in your organization is a great way to provide a haven for these talented devs, while simultaneously making your team more productive and easing the pain of hiring.
In this talk, you'll learn from the mistakes I've made and wins I've had in creating an apprenticeship. From pitching the idea to growing your apprentices, you'll gain a step-by-step guide to successfully building your own apprenticeship program.
Building a business is both mysterious and hard. We can't do much to make it easier, but after 6 years running Test Double, we can make it less mysterious. This talk is a slow-motion Q & A: submit a question to http://testdouble.com/business and we'll build a slide deck that gives as many practical (and colorful) answers we can fit in a 45 minute session.
This talk is for anyone whose interest in starting a software company has ever been held back by fear, uncertainty or doubt. It assumes no knowledge of business jargon and will strive to explain each financial concept covered.
Upgrading Rails at Shopify has always been a tedious and slow process. One full upgrade cycle was taking as much time as it takes to release a new Rails version. Having a full time dedicated team working solely on upgrading our platform wasn’t the solution but instead a proper process and toolkit. In this talk I’d like to share the different techniques and strategies that allowed to perform our smoothest and fastest Rails upgrade ever.
Come see how Rails has evolved over the years through the lens of introductory Rails tutorials. Marvel at Rails pre-REST, survive the merger with Merb, feel the joy & pain of the then-new asset pipeline, and watch testing techniques grow, evolve, and simplify. Leave with a deeper appreciation for where Rails came from and where it is today.
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.
So you have something new to sell: maybe your first book or a hip new SaaS. How do you decide the price? How do you know you're not overpricing? Or underpricing? Why, oh why, did you ever think to sell something?!
Instead of choosing a number by looking inward at your costs, you can use what programmers use best: an abstraction! You'll learn a model for picking the right price for your product and what that price communicates so you can confidently price your next great invention. You'll leave with an actionable list of next steps for pricing your future projects.
On March 28, 1979 at exactly 4:00am, control rods flew into the reactor core of Three Mile Island Unit #2. A fault in the cooling system had tripped the reactor. At 4:02, the emergency cooling system automatically kicked in as reactor temperature continued to climb. At 4:04, one of the operators switched the emergency cooling system off, dooming the reactor to partial meltdown. Why?
Let’s let the incredibly complex failure at Three Mile Island teach us how to dig into our own incidents. We'll learn how the ideas behind just culture can help us learn from our mistakes and build stronger teams.
Rails has a reputation for being secure by default, but how deserved is that reputation? Let's take a look back at some of the low points in Rails security history: from the first Rails CVE, to the controversial GitHub mass assignment, the 2013 Rails apocalypse, and more recent remote code execution issues. Then we'll cheer ourselves up with the many cool security features Rails has added over the years! We'll cover auto-escaping, strong parameters, default security headers, secret storage, and less well-known features like per-form CSRF tokens and upcoming Content Security Policy support.
We know how to communicate — we do it on a daily basis, so why spend time perfecting something you feel you already know how to do? Well, what you say and how you say it impacts how you are understood and how others perceive you. In written communication, a single missing comma can wildly change the meaning of what you said. In this talk, we'll walk through 5 tips that improve how you communicate. Using real world examples, we'll show how common these pitfalls are and how to overcome them. You'll leave armed with the ability to positively impact your relationships through how you communicate.
Polymorphism is a mainstay of the Ruby on Rails stack, affording us a lean, concise way of relating objects in a dynamic way. Using a candy shop application, this presentation will pragmatically explain and demonstrate polymorphism and its benefits/usefulness in Rails.
So this one time we ran Rails services over AMQP (instead of HTTP). You may be thinking “Why? Was that their first mistake?” It was not. From handling shared models poorly to deploying & operating services with inadequate tooling, we've made...so many mistakes. I'm glad we did; they helped us grow. We have patterns & practices for everything we’ve seen so far, from API contracts to distributed consensus protocols. Over this talk’s 40 minutes, you'll learn things it took us 3 years to grasp. Whether you have a monolith or pine for when you did, you'll be more prepared and better armed than we were.
Postgres 10 is out this year, with a whole host of features you won't want to miss. Join the Heroku data team as we take a deep dive into parallel queries, native json indexes, and other performance packed features in PostgreSQL. Whether you've got no idea what Postgres version you're using or you had a bowl of devops for dinner, you won't want to miss this talk.
This a sponsored talk by Heroku.
Have you ever had a crazy idea that you were quietly convinced was great, but that everyone else thought was dumb? Well guess what: the future of Rails is depending on you.
I’d like rewind time by more than ten years, to tell you about one particular crazy idea that almost everyone hated, until it quietly became one of the core architectural components of Rails.
At the same time, we’ll meet the crazy ones, the misfits, the rebels and the trouble makers that ended up shaping Rails as we know it… and maybe, just maybe, we will realise that we can be one of them too.
Lying on the beach and enjoying the 4-hour work week: who wouldn't like the recurring revenue stream of a SaaS business? It's why many start building a SaaS company "on the side", only to find out they don't make enough money to buy a latte and fall back to getting paid by the hour. They're stuck on the long, slow Ramp of Death.
Coming to you live from the trenches of running an organically growing SaaS for five years, this is an honest –and sometimes brutal– story of perseverance, sacrifice and reward. Find out how to overcome the ramp, and why it isn't as bad as you might think.
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.
Contextual Camouflage is an open-source gallery art installation built in RoR that guides visitors to anonymously report mental health disorders that affect themselves or their relationships. After users submit a disorder, they have the option to include anecdotes and demographic data for intervention researchers. The data is molded into an interactive real-time display using ActionCable. Come see how code can double as art and an educational tool.
Sharding is a heated topic and many who have tried it have come away with a bad taste in their mouth. But it's also well proven that sharding your database is the true way to scale the data layer. From Instagram to Google to Salesforce, with large-enough data and with sufficiently demanding performance requirements, you need to shard in order to scale out. Using the lens of the Postgres open source database, I'll walk you through things to keep in mind to be successful with sharding, and which data model is the right approach for you.

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.
Production support is not a priority. No one on the team wants to work on support cards. Being on-call is a pain. Does this ring a bell? We've all been there! There is a better way to handle Support Engineering for your product. A way that will level up your team, and create positive support experiences for your customers. Drawing on 3+ years of Support Engineering at two different companies, I will share successful Support patterns and tools you can start using today to improve your product support.
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.
Rails is a great framework to empower people to work smarter, not harder. I'll be sharing the evolution of technology in a Pittsburgh brewery, from a simple MVP to a production application. This talk will explore how Ruby and Rails was leveraged to help manage brewery data, control aspects of the taproom environment, and automate the tedious parts of the job to a few clicks.

Ready to containerize your Rails application? Then this session is for you. We'll walk through the process of deploying a nontrivial Rails app to Kubernetes, focusing on effective container design. You'll learn techniques and best practices for constructing images and orchestrating your deployment, and you'll come away understanding how to optimize the performance, flexibility, and security of your containerized application.
This is a sponsored talk by Google Cloud Platform.
Have you ever clicked "Save" on a document, and caused a coworker to lose hours of work? Or spent more time coordinating "Who has permission to edit" in Slack than you did actually writing the document?
Google-Docs-style collaboration used to be nice to have. Now, it's expected. Companies like Quip and Coda have based their business on real-time collaboration features. Atom and Sublime Text have collaborative editing plugins. Even Confluence now supports collaborative editing!
In this talk, you'll learn how to build a great collaborative experience, based on solid fundamental ideas.
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.
Your application is a dragon and here’s how we’re going to form a successful raiding party to come out victorious (with minimal casualties!). When entering the field of web development, I discovered that the parallels of building a strong multiplayer gaming community and optimizing companies for success were undeniable. Your quest, should you choose to accept it, is to listen to these parallels and use the lessons to strengthen your biggest asset-–your team–-to build a better company and a better web.
Machine learning and AI are all the rage, but there’s often no replacement for real human input. This talk will explore how to automate the integration of human-work directly into a RoR app, by enabling background workers to request and retrieve data from actual human workers. The secret is Amazon Mechanical Turk, a crowdsourcing marketplace connecting ‘requesters’ who post tasks with ‘workers’ who complete them. Attendees will learn how to automate the completion of human tasks (e.g. price research, image tagging, sentiment analysis, etc) with impressive speed, accuracy and scalability.

It’s easier than ever to integrate a distributed commit log system like Kafka into your stack. But once you have it, what do you do with it? Come learn the basics about Kafka and event-driven systems and how you can use them to power your Rails services. We’ll also venture beyond the theoretical to talk about practical considerations and unusual operational challenges that your event-driven Rails services might face, like monitoring, queue processing, and scaling slow consumers.
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!
We put a lot of effort into web speed for our website dev.to. One day in November we woke to our greatest traffic day ever, and the source was Japanese Dev-Twitter catching wind of just how fast a site could be. American websites don't typically give so much care to global performance, but it pays off if you do. In this talk I will describe how we think about performance.
Let us show you the easiest way to build, deploy and manage any Rails application on any cloud provider and under your own cloud account. We will also show you how to scale your databases, setup database replication and add off-site backups to your databases with extreme simplicity. Find out how to spend less time configuring boxes, and more time developing great web apps!
This is a sponsored talk by Cloud 66.
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.
Applying the tried and true answers of “It depends.”, “Maybe?”, and “It works for me, what if you try …” to our engineering organizations themselves turns out to work better than trying to find the One True Way. We all know that every engineering project is full of trade-offs, caveats, surprising complexities, and hidden depths; so it should be no surprise that we, the engineers who build such systems, are at least as complicated.
This is a sponsored talk by Procore.
Rails 5.2 ships with a new library to support file uploads: Active Storage.
In this talk, we will analyze its internal code, learning how it integrates with Active Record and Action Pack to supply amazing features out of the box, from image previews to cloud storage.
We will review its class architecture and delve into the implementation of several Active Storage methods, such as has_one_attached and upload. On the way, we will better understand some Ruby patterns frequently used within Rails: meta-programming, macros, auto-loading, initializers, class attributes.
If you've ever had inconsistent data show up in your app even though you wrapped the relevant code in a transaction, you're not alone! Database isolation levels might be the solution...
This talk will discuss what database isolation levels are, how to set them in Rails applications, and Rails-specific situations where not choosing the right isolation level can lead to faulty behavior. We'll also talk about how testing code that sets isolation levels requires special care and what to expect to see when monitoring your apps.
Upgrading Rails can go from easy-to-hard quickly. If you've struggled to upgrade to a new version of Rails, you're not alone. And yet, with useful deprecation warnings and extensive beta periods, Rails has never made it easier to upgrade. So what makes it hard?
By looking at the past ten years of Rails upgrades at Clio (and other notable apps), let's see what we can learn. Gain insight into the tradeoffs between different timelines and approaches and learn practical ways to keep your app up-to-date.
Pilots have the flight deck, Captain Kirk had his bridge, but what do you have for managing failure in your application?
Every app comes under stress, whether it's from downstream failures to unmaintainable high load to a spike in intensive requests. We'll cover code patterns you can use to change the behavior of your application on the fly to gracefully fail.
You’ll walk away from this talk with tools you can have on hand to ensure you remain in control even when your application is under stress.
Do you keep telling yourself you want to get into open source? Have you been thinking about contributing to Rails? Don’t know where to get started? Right here! Come learn about how to find an interesting issue to work on, set up your dev environment, and ask for help when you get stuck. We’ll also talk about what happens after the first patch and where to go from there.
You run rake db:migrate and rake db:schema:load regularly, but what do they actually do? How does rake db:rollback automatically reverse migrations and why can't it reverse all of them? How can you teach these tasks new tricks to support additional database constructs?
We'll answer all of this and more as we explore the world of schema management in Rails. You will leave this talk with a deep understanding of how Rails manages schema, a better idea of its pitfalls, and ready to bend it to your will.
As you’re building out your app, you know how important it is to have your database up at all times. You need your PostgreSQL database to be HA. Jake from Compose is going to show you how to migrate your data to a HA PG service in less than 20 minutes.
This is a sponsored talk by Compose, an IBM company
It's the afterthought of every system, scrambled together in the final days before launch, updated sparingly, generally out of date.
What if we could programmatically verify that our API documentation was accurate? What if this helped us build more intuitive APIs by putting our users first? What if documentation came first, and helped us write our code?
With Swagger and Apivore as our weapons of choice, we'll write documentation that will make your APIs better, your clients more satisfied, and you happier.
An ode to DHH's classic, let's build a blog with a Rails backend using a graphQL API and a React frontend. Through this live-coding session, you will learn how to set up an isomorphic app, the basic concepts of each library, and at the end have a fully functioning blog application! Follow along on your computer or clone the repo.
LendingHome is on a mission to simplify the mortgage process, but that’s not always easy in a world where we hear “API? What’s that?” from our third-party vendors. For the ones that do have technology solutions the phrases “FTP” and “Fixed-Width” are frequently thrown around.
This talk will dive into the solutions we’ve built that abstract away some of these concepts and how we provide clean interfaces for these services to the rest of the organization. If you’ve ever wanted to learn how modern companies interface with the old, this is the talk for you.
This is a sponsored talk by LendingHome.
Content warning: This talk includes brief stories about sexual assault and IEDs in Iraq.
Fear is not a gut feeling. Fear is your brain delivering critical information derived from countless cues that have added up to one conclusion. Stop. Get out. Run.
But sometimes fear isn’t life or death. Often, it’s code smell. It’s a bad feeling before a deploy. This talk will explore fear, instinct and denial. We’ll focus on our two brains — what Daniel Kahneman describes as System 1 and System 2. And we’ll look at how we can start to view “feelings” as pre-incident indicators.
Test All the F***ing Time is one of the values of the Ruby community. But how many of us test in production in addition to running our test suites as part of CI? This talk will discuss a variety of approaches to testing in prod including canaries, blue-green deployment, beta and A/B tests, and general functional tests. I'll share a few times these techniques have found bugs before our users did and how you can use them today with your Rails Application.
“Everything looks like this, but we want it to look like that.” This is the story of how the team at Betterment replaced our front end code base to launch our new brand. Across all our apps. In secret. And make everything responsive. In 8 weeks.
Rails conventions come in handy when a wholesale UI transformation is called for. Learn how we launched a design system, dark deployed an all-new view layer, and unveiled our new brand identity right on schedule.
We shipped a lot of code extremely quickly yet managed to elevate code quality and capabilities in the process.
Constraint breeds creativity.
Perhaps you've thought about switching to Webpack. Then you open a Webpack config file and your heart sinks; it looks like an alien life-form. You try to get it working, but your old jQuery plugins won't even load in the browser.
Moving from Webpack basics to using it in production means understanding how it works. We'll demystify how Webpack bundles assets for the browser, how it differs from the Rails asset pipeline, and highlight common challenges that may occur coming from Sprockets.
This is the talk we would have wanted to see before recently adopting Webpack in our own Rails app.
Have you ever been frustrated with code that is sprinkled with poorly named classes, methods, and variables?
One of the most valuable things you can do as a developer is to choose good names and to sensitize your teammates to the benefits of improving names.
It turns out that improving names is deeply connected to improving design. And vice-versa. You will see and experience this deep connection as we explore a real world example.
By the end of this talk, you will have learned a process to get you started with improving names and improving design—a process simple enough for you to teach others.
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.
We are told that junior developers are a secret weapon, but this alleged "competitive advantage" is so elusive! Typical advice about evolving talent can be broad, un-relatable, and impractical. Aren't there any specific and actionable tactics that teams can employ for leveling up new devs? (Yes, there are!)
