Forecasting the Future: Intro to Machine Learning in Ruby (RailsConf 2023) Test Double 2023-07-24 | Inspired by a desire to understand why more engineers weren't using Ruby for their machine learning (ML) projects, I embarked on a journey to determine if I could build a project to do something non-trivial using ML in Ruby. Once again, it turns out that you can indeed use Ruby to do amazing things! By leveraging various libraries, building machine learning models becomes a breeze.There is a large array of tools, libraries, and resources available that help facilitate the construction of ML models for Rubyists, and the list keeps growing. Now has never been a better time to dive into machine learning and build interesting projects. It is clear that AI has dramatically shaped the software industry. As such, it makes sense that Rubyists will also partake in these rapidly evolving technologies and create tools and applications never before thought possible!More info and resources on the Test Double blog at blog.testdouble.com/talks/2023-07-24-forecasting-the-future
Zero downtime Rails upgrades (RailsConf 2023) Test Double 2023-07-23 | No one likes working on Rails upgrades, and who can blame them? They can be thankless, time-consuming, and—worst of all—unpredictable. How long will they take? When can we get back to feature work? What’ll break when they’re deployed? It’s tempting to say, “Let’s do it later,” but later is usually never. Instead of living in fear of the big, scary Rails upgrade, your team can set up systems for incremental change that let you:- continue feature work- deliver predictable results- seamlessly jump into the next upgrade (because there’s always a next upgrade)And Ali is gonna show you how.In the years since he's worked on upgrading Rails at GitHub, Ali refined an approach to Rails upgrades and successfully implemented it at several organizations. In this talk, you’ll learn everything you need to burn down uncertainty and boldly go into your next Rails upgrade.More on the Test Double blog, including resources, at blog.testdouble.com/talks/2023-07-23-zero-downtime-rails-upgrades
The end of legacy code (RailsConf 2023) Test Double 2023-07-19 | What if you could change your relationship with legacy code, and shed the weight the name brings with it? What if legacy code disappeared? In this RailsConf 2023 talk Daniel Huss shares how.If we try to approach legacy code with a fresh perspective, we can find opportunities to smooth out the rough edges and make it easier for other devs, and our future selves to work with.If we don't, we risk pushing ourselves and the team we're on into a salty mindset, and towards burnout.By eternally onboarding to a legacy system, we can help take pressure off our code so it's not responsible for things code is bad at doing.More on the Test Double blog at blog.testdouble.com/talks/2023-07-19-end-of-legacy-code

Building a Linkblog with Hugo, Tailwind, and NetlifyCMS Test Double 2022-11-23 | With Twitter on shaky ground, there's a sudden interest in open social platforms and protocols as well as a return to hosting traditional web sites and blogs. But because we've become accustomed to low-friction publishing workflows (type a bit in a box, click Tweet), routinely writing real blog posts can feel daunting.This video provides a brief overview of one way to organize a personal blog that's structurally similar to daringfireball.net—allowing for short-and-sweet posts—but with modern architecture of Hugo for static site generation, Tailwind for styling, and Netlify (plus NetlifyCMS) for hosting and on-the-go publishing—enabling very low-friction publishing.* Hugo - gohugo.io* Tailwind - tailwindcss.com* Netlify - netlify.com* NetlifyCMS - netlifycms.org* Justin's CSS overrides to make NetlifyCMS more mobile-friendly -gist.github.com/searls/7fd2c3223571a58a81006e7da66bd064
A Better Way to Sort Ruby Objects Test Double 2022-09-28 | Ruby offers a super convenient method for sorting complex objects in Enumerable#sort_by.

How to Trust Again Test Double 2022-02-09 | Why has trust become so rare in the software industry? Developers don't trust their own ability to program, teammates don't trust each other to write quality code, and organizations don't trust that people are working hard enough to deliver on time.This talk is a reflection on the far-reaching consequences distrust can have for individuals, teams, and organizations and an exploration of what we stand to gain by adopting a more trustful orientation towards ourselves and each other.Full description and transcript here: blog.testdouble.com/talks/2022-02-09-how-to-trust-again

Under Pressure (Todd Kaufman) Test Double 2020-03-11 | It’s an accepted truth in software development; when deadlines loom the team will be pressured to GO FASTER. Unable to convince management of the risks, we resign to cutting corners and working longer hours. Unfortunately the result is just as predictable, a short spike in velocity and many delays to come.This talk is an exploration of how to reverse the velocity spiral by building high trust relationships with management. We’ll discuss root causes of our distrust like estimation, communication, and abuse of power so that the team can resist short sighted solutions that will plague them for years to come.More here: blog.testdouble.com/talks/2017-05-31-under-pressure
A Better Technical Interview (Sam Jones) Test Double 2020-03-11 | It’s easy to find fault in the way we interview in tech. Often, there are unclear goals, trivia questions, and unrealistic coding environments. Let’s analyze the things we don’t like, and design a better process. Let’s make a better technical interview with honesty, transparency, and a more realistic experience.More here: blog.testdouble.com/talks/2017-01-27-a-better-technical-interview
Solving the Boolean Identity Crisis (Jeremy Fairbank) Test Double 2020-03-11 | While powerful in its simplicity and important to computation, the boolean can be extremely limiting in Elm applications. In this talk, briefly explore the history of boolean logic in computation and look at how booleans can become misused in Elm. See how booleans obscure the meaning of code, make code harder to maintain, and hinder usability for our teammates and users. By watching this talk, you will learn how to harness union types to write cleaner, clearer code. More importantly, you will learn how to place usability at the forefront of the APIs and UIs you build.More here: blog.testdouble.com/talks/2017-10-06-solving-the-boolean-identity-crisis
JavaScript is too convenient (Sam Jones) Test Double 2020-03-11 | Which conveniences do we take advantage of everyday? Which are taking advantage of us?Objects and functions sure are convenient, so convenient that we do many shortsighted things just because they’re easy.In-line objects and anonymous functions create a poor signal to noise ratio, making it hard to understand your code.Learn ways to give confusing things names, focus on what’s important, and write nicer code.More here: blog.testdouble.com/talks/2018-05-02-javascript-is-too-convenient
Going To Eleven (Steve Jackson) Test Double 2020-03-11 | This is the story of a real-life product “land rush”. It starts with designing a load test, picking tools, and isolating a slew of dependencies. That’s the easy part. The fun really starts when the load test runs. Hold on tight and we’ll ride this swarm to the finish line.More here: blog.testdouble.com/talks/2017-05-31-going-to-eleven
Better Software Through Shared Understanding (Steve Jackson) Test Double 2020-03-11 | This talk takes a step back from the toolbox to ask: What are the core benefits a tool should provide?As a project grows up, it has different needs and benefits from differing levels of “discipline”. Likewise, people have differing comfort levels for process rigor.Too often we focus on the laundry list of benefits that we might get from a tool without considering the maturity of our project or the composition of the team. We want to build shared understanding without dictating a process that crushes diverse thought and collaboration.This talk proposes examples as a universal way to build shared understanding without tying a team to specific tools or implementations.More here: blog.testdouble.com/talks/2017-05-18-shared_understanding
Effective React Testing (Jeremy Fairbank) Test Double 2020-03-11 | Many teams relish building applications with React these days. Composable components and unidirectional data flow with Redux create a solid foundation for modular applications. By this point, you know higher-order components, selectors, and render props like the back of your hand. But what about testing?If you neglect to write React tests because you don’t know what to test, which types of tests provide the most value, or how to start testing, then this talk will guide your path. I explain the difference among unit, isolation, and end-to-end tests, and provide a general framework for how to test your application.You will learn about the testing framework Jest, how to test-drive components with Enzyme for design feedback, the magic and trade-offs of snapshot testing, how to unit and integration test your reducer and actions, and how to test your entire application in a browser by simulating user scenarios. Of course, I offer both pros and cons to each type of test, so you and your team can discover what works best for you. You will also learn how to use our nifty testdouble.js library.More here: blog.testdouble.com/talks/2018-04-09-effective-react-testing
Life After Nil (Sam Jones) Test Double 2020-03-11 | There are murmurs that a type system will be coming to Ruby. Before that happens, you should get informed about what is hot in the current type system market. Haskell is known for its type system, but instead of describing it with dense language, let’s take a journey through code examples. Throughout our trip, we will avoid scary buzzwords like “monad” and “algebraic data type” because, honestly, what good is a formal definition when you don’t understand the power behind the concept?We will compare solutions in Ruby to solutions in Haskell, and each stop on our trip will introduce a new mind-blowing paradigm brought to you by Haskell’s type system. You will learn about type systems through a non-threatening story, and you’ll understand the value a type system can bring to your code. Key stops on our route will be “forget about nil”, “declaratively model your domain”, and “allow your compiler to drive your design”.More here: blog.testdouble.com/talks/2017-01-18-life-after-nil
Looking for Failure (Steve Jackson) Test Double 2020-03-11 | Failures are interesting. They tend to teach lasting personal lessons, but we are loath to share them. These lessons have profound impacts on our habits and viewpoints, but they’re difficult to recount. We need to get comfortable talking about failure. Unfortunately, our brains are wired to screw this up. When confronted with a failure, we are conditioned to ignore it, make ourselves blameless, or create elaborate strategies to avoid the possibility of failure altogether. I’d like to present another alternative: embrace failure. It will happen. That’s ok.How can we challenge our natural human bias? I’ve spent the last couple years digging into “pop” psychology and thinking about how books like “Thinking Fast and Slow”, “Antifragile”, “Drive”, “Blink”, and “Outliers” apply in a software development environment. I’m most excited about the idea that if we can make failure “safe” then we can use it to learn things that we would otherwise be tempted to avoid and ignore because it might go badly. A focus on failure, both deliberate and accidental, has been beneficial in moving my projects beyond the no defects, 100% test coverage type focus and towards finding innovative ways to detect and quickly reverse failure.More here: blog.testdouble.com/talks/2017-07-31-looking-for-failure
