Does Behaviour Driven Development work? Unfortunately, it usually does not. While many people try to pitch as a way to bridge the gap between stakeholders on the project, many teams fail to communicate their test scenarios with everyone involved. Although this fundamental problem of lack of communication can be solved on the organization level, BDD is often used with Cucumber or Robot frameworks. Due to the complexities of these tools, developers and testers stop seeing the benefit in the entire approach of BDD and abundant the practice. However, recently, Behavior Driven Development has seen a resurgence in adoption, thanks to Gauge framework. With the latest release of Taiko, they create a great combination of communication and testing tool with the use of Gauge+Taiko. In this talk, we will discuss BDD principles and how Gauge can be used to take Behavior Driven Development to the next level. With Taiko, the audience will learn how BDD can be taken to the web in a few easy steps and to see what needs to be avoided when these tools are implemented in any organization.

MQ, ETL and ESB middleware are often used as integration backbone between legacy applications, modern microservices and cloud services. This introduces several challenges and complexities like point-to-point integration or non-scalable architectures. This session discusses how to build a completely event-driven streaming platform leveraging Apache Kafka’s open source messaging, integration and streaming components to leverage distributed processing, fault-tolerance, rolling upgrades and the ability to reprocess events. Learn the differences between a event-driven streaming platform leveraging Apache Kafka and middleware like MQ, ETL and ESBs – including best practices and anti-patterns, but also how these concepts and tools complement each other in an enterprise architecture.

Catalyst is becoming one of the most important components of Apache Spark, as it underpins all the major new APIs in Spark 2.0 and later versions, from DataFrames and Datasets to Streaming. At its core, Catalyst is a general library for manipulating trees. In this talk, Yin explores a modular compiler frontend for Spark based on this library that includes a query analyzer, optimizer, and an execution planner. Yin offers a deep dive into Spark SQL’s Catalyst optimizer, introducing the core concepts of Catalyst and demonstrating how developers can extend it. You’ll leave with a deeper understanding of how Spark analyzes, optimizes, and plans a user’s query.

“I tested it how you told me to,” “Requirements say it's expected,” “I assumed it's fine” – these are the common phrases you hear when customer cases come up. Unfortunately, it is nothing unusual in our industry to be detached from customers' actual needs. As a result, teams regularly fail when they prioritize requirements over actual behaviour that the customers expect. This problem of misaligned teams' focus is where Domain Driven Testing (DDT) comes into play. DDT helps developers to put themselves into the customers' shoes and see the product for what it is. This prioritization of the actual behaviour over the mere following of the requirements is what defines Domain Driven Testing. In this talk, we discuss how knowledge of your company's domain (aka, the focus of your business) can improve your testing practices. We talk about Domain Driven Design techniques, Exploratory Testing, and other methods which emphasize software quality through customers' success. We touch bases on tools you can integrate into your system using Domain Driven Test Pyramid, and what common mistakes you should avoid when implementing Domain Driven Testing.

Do you ever worry that your testing skills are too limited for your company? Are you concerned that other organizations, especially the ones with a massive scale, require a completely different set of skills? Worry no more! This talk will look at how testing is done at companies with the scale of the likes of Salesforce and Meta. We will discuss how the most basic testing skills and tools we use daily are transferable to any company.

Do you remember those games where you had to find differences between two almost identical images? If you've ever made changes in production, you sure played this game of searching for any visual changes you might have caused. The problem of catching visual regressions is what gave rise to a new way of testing - visual testing. While developers focus on automating their end-to-end flows with tools like Selenium, when it comes to end-to-end visual testing, many are at a loss. It is even more apparent in the world of mobile development, where devices differ in their capabilities, display dimensions and even operating systems. Hence, visual testing is a must-have in the mobile market! In this session, we discuss how to implement visual testing on mobile devices covering both native mobile (Android, iOS) and hybrid web development (React, React Native). We cover major visual concepts like layouts, responsive design, and graphics which should give the audience a clear picture of how to get started and be successful with visual testing.

Quantity or Quality – this is a common dilemma we all face when buying groceries, going to the restaurant, or shopping online. Unsurprisingly, when it comes to testing software, the same question of quality over quantity comes up. “How many tests?”, “How well to write them?”, “How much testing expertise do you need?” - all these questions aimed towards the same dilemma of quantity vs. quality. In this talk, we will discuss situations when quantity of our tests takes over their quality. We will answer a question on how this tendency of writing many unnecessary tests creates even larger issues like wasted cycles on fixing test-only failures, on maintaining existing test suite and on creating every new test from scratch. Whether you are currently facing these concerns, or when (not if) you are going to face this issue, this talk will give you necessary skills on how to address and more importantly how to prevent poor quality of the test code. The speaker will share his experience in working with legacy test suites, creating overly complicated tests himself, and how he tackled these challenges. Along with his experience, the speaker will rely on Software Engineering principles which are popularized among developers but not as commonly used by the tester community. The main takeaways of this talk will be for testers to look at their code the same way developers look at production code. In essence, we will blur the line between testing and development and learn how to take the best from development and apply it to our tests; best of both worlds.

How confident are you in your React app? Does your UI render after you add a new item to the nav menu? What about style changes - do you know how a font change affects the rest of your app? If you want to have confidence in your React app, you need to have tests. Unfortunately, most testing frameworks are hard to set up, and it takes too long to run them. But this is not the case with Jest! Jest allows React developers to get a quick test result for any change on the app. And setting up Jest on React has never been easier than today! In this talk, we look at how React apps are tested E2E and why Jest stands out compared to other test frameworks. We do a live demo while implementing several main test scenarios using Jest - get ready to code along!

As Developers, we are getting lazy! With amazing IDEs and plugins we use on a daily basis, we let these tools do the most important job for a Software Project – ensure maintainability of the codebase. These tools with static analysis, formatters and styleguides keep our code clean and readable while we can focus on making the application to work. Despite this abstraction of styling and duplication detection, we, as Software Engineers, are still responsible to keep in mind best practices like DRY, KISS, YAGNI, and many more. While IDEs are great at detecting basic mistakes, we still need to choose the best possible solution among variety of solutions. In this talk, we will look at Kotlin as a way to enforce best Software Engineering practices on the language-level. We will see how Kotlin by limiting verbosity, by using private data classes, extension functions and many other functionalities, allow for more flexible and maintainable codebase. The main goal of this talk is to convince you that Kotlin is a great way to bring years of experience of using best practices to a first-year university student, or to a long-time Java veteran.

It's no secret that people view the same website across many devices, browsers, and screen sizes. To make the same app work on all these platforms, developers have to spend a significant amount of time. If only there were an engine that allows web developers to write their code once and use it everywhere. Presenting Yoga, an open source, cross-platform layout engine that uses CSS layouts to manage user interfaces across platforms. In this talk, we learn about Yoga's main concepts and use-cases. Then, we will build a demo app for React Native and Android to showcase the reusability of Yoga.

Do you know how to get someone to do something difficult? Make it easy! Documentation is one of those things: everyone understands it's important, but few want to write it. And if the docs platform is difficult to use or extend, doc writing becomes a punishment. Docusaurus is here to help! In this session, we will walk through getting started with Docusaurus, its architecture and MDX support. We will explore built-in themes with plugins, and even create one during the talk. So, let's learn how to make doc writing enjoyable, together!

We all encountered a “Broken Window” theory in practice. The original idea was that if someone breaks a window in a neighborhood and this window is not repaired right away, the entire area will start getting messier at an accelerated rate. The same theory is also true for Software Development. How many times have you looked at a legacy system with no code coverage, and decided not to write any tests because "this is how we do things here"? These bad practices behave just like those "Broken Windows." They cause our code to degrade and become unusable. In this talk, we discuss how to break away from bad development practices and how to address significant gaps in your legacy and current systems. We look at ways to lead by example successfully and introduce refactoring culture into your team and organization. We cover tips and tricks that help improve the development culture and emphasize the codebase's general health.

What do most applications do these days? They interact with data in one way or another. As your app’s scale increases, it becomes more challenging to manage databases, schemas, queries, and constraints. These challenges are why a technique called Object-Relational Mapping, or ORM, was created. At Meta, we tend to think about data modeling in graph concepts and as we were working with Go, it led us to create a new open source project, Ent. Ent is an entity framework built for Go programming language. This framework provides developers with a Graph-based, Object Relational Mapping. In this talk, we will learn how to use Ent when dealing with data schemas, including types, relations and constraints. It’s a hands-on talk, so get ready to follow along!

Human health is complex - it's not something we can buy; it's something we have to earn! This exact approach goes for open source projects and their communities. A truly dedicated and loyal fanbase cannot be bought; it has to be nurtured. But what do we mean when we call a community and the open source project "healthy"? This question is what we are trying to answer at Facebook! In this talk, we will look at the approach that the Facebook Open Source team takes to measure the current state of Facebook open source projects, and how we use these metrics to prioritize and to direct our DevRel focus. Ultimately, we aim to show how by looking at information about your open source communities, your team can concentrate on the quality of the projects instead of only the quantity of repositories that you make public.

Selenium WebDriver has been the traditional testing standard for many years. However, many developers have concerns over test speed, maintenance, and implementation. Fortunately, new, non-Selenium frameworks like TestCafe and Cypress.io rely on Rapid Test Development practices which address common issues teams have with their old test infrastructure. In this talk, we dive into platform-specific Selenium solutions like Protractor, and discuss non-Selenium frameworks like TestCafe and Cypress.io.

Object-Oriented Programming - it is often synonymous with Java Development. But what if I were to tell you that there is more to Java than OOP principles? Starting JDK8, Java language introduced a new and exciting world of Functional Programming. This inherently powerful paradigm drives services like AWS Lambda, Azure Functions, or any other Function as a Service product out there. Functional programming offers better security, simpler maintenance, and more flexible design, so it is vital for Java developers to embrace this paradigm and learn how to use it well. In this talk, we discuss how to apply Functional programming in Java with the primary focus on Functional Interfaces. We explore out-of-the-box Functional structures, how to build custom Functions and look at common mistakes of impure abstractions and overly-DRY design.

Mobile Testing is hard! You have to test not only Native Mobile but also Web-based applications. This multi-platform focus makes the testing effort to be at least twice as complicated as when a simple web application is targeted. With the growing market around smartphones, developers needed more ways to ensure software quality of their product. This need is why many mobile UI test frameworks have been introduced. With the most significant share of the mobile market being taken by Android OS, development and testing efforts have been especially crucial in this ecosystem. Among the variety of Mobile UI automation tools, two frameworks have been especially notable: Robotium and Appium. However, with more organizations moving towards multi-platform solutions, those of us, who used Robotium, are slowly moving towards Appium. This journey from Robotium to Appium is where the main focus of this presentation lies. In this session, we deep dive into both Robotium and Appium. We discuss why and how to transition from Robotium to Appium in the Android ecosystem. Lastly, we look at common mistakes made during this transition, and how to avoid them.

When was the last time you took a day off? How many times this week have you worked overtime? These questions are related to one thing we all experience on a daily basis - stress. Employees who are trapped by their routine to "deliver business value at all cost", often forget to take care of themselves. Unfortunately, this work-related stress affects our loved ones too, because work-life balance that we all hear about, usually means work-life stress. What if I were to say that it does not have to be this way? In this talk, we discuss ways how to relax and avoid "Stress Driven Development." We deep dive into common stressors, and draft a comprehensive guide to removing stress at work and in our personal lives.

Callback hell is a known way to give any JavaScript developer nightmares. However, Java developers are not much better off since anything concurrency and multithreading related gives us cold sweats. With Threads and Runnables being the very first (and often last) things we used in Java, these classes gave many of us impression of and appreciation for complexities of concurrency. As a result, many developers abandoned the idea of ever touching thread management in Java and focused on a single-threaded development. Fear no more! The world of concurrency in Java has changed since JDK8 and continues getting better. In this talk, we discuss improvements around Concurrency API of JDK5 and the power of asynchronous programming of CompletableFutures post-JDK8. Our goal is to break out of the fear of concurrency in Java and to learn about a new, declarative way of thread programming.

It is safe to say that Selenium WebDriver is the number one testing tool for many software engineers across the globe. However, as the tech world has been growing rapidly, so has the testing industry. More and more UI testing frameworks besides Selenium are gaining popularity. These new test frameworks are especially appealing to its users because of the promise to solve speed, maintenance, development and other concerns of WebDriver implementations. These new, non-Selenium frameworks emphasize Rapid Test Development practices, and it has been resonating with the development community. In this talk, we dive into test solutions evolved from Selenium like Protractor, and talk about non-Selenium frameworks like TestCafe and Cypress.io. We discuss why these new tools are gaining popularity and continue to disrupt the traditional testing standards of Selenium WebDriver. More importantly, we address how to get started and what mistakes to avoid when first implementing TestCafe or Cypress.io in your team.

Technologies like Squarespace, Salesforce, WordPress, or WIX are extremely popular for those who want to create a working website without necessary developer knowledge. In this talk, I would explore how Salesforce uses Page Object Model patterns to test its Communities platform which is used to develop websites for Salesforce users. Throughout the talk, we will explore how multi-frame platform can be directly mapped to POM for Selenium Webdriver, and how client side code is developed to support this pattern. The importance and complexity of these test framework is that it needs to be applicable for both platform and produced websites. Recording: https://youtu.be/6opoooLdonI

AI/ML Infra Meetup May. 23, 2024 Organized by Alluxio For more Alluxio Events: https://www.alluxio.io/events/ Speaker: - Junchen Jiang (Assistant Professor of Computer Science, @University of Chicago) Prefill in LLM inference is known to be resource-intensive, especially for long LLM inputs. While better scheduling can mitigate prefill’s impact, it would be fundamentally better to avoid (most of) prefill. This talk introduces our preliminary effort towards drastically minimizing prefill delay for LLM inputs that naturally reuse text chunks, such as in retrieval-augmented generation. While keeping the KV cache of all text chunks in memory is difficult, we show that it is possible to store them on cheaper yet slower storage. By improving the loading process of the reused KV caches, we can still significantly speed up prefill delay while maintaining the same generation quality.

In his book, The Nature of the Physical World, Sir Arthur Eddington commented that “We have to appeal to the one outstanding law — the second law of thermodynamics — to put some sense into the world.” This sense-making goes beyond the physical world, too. Entropy is also essential in the fields of information and communication theory. During this lecture for the Princeton Plasma Physics Laboratory, lecturer Andrea Goulet discussed the application of entropy-related concepts in two communication systems: software and collaborative teams. She examined how concepts that help us understand systemic statistical disorder, such as ergodic systems, Lyapunov exponents, Kolmogorov-Sinai entropy, and Shannon-entropy can help us optimize for both software quality and innovation. She also provided several domain-specific models: Lehman’s Laws and Conway’s Law for software, as well as new models from her own research that relate to entropy and innovation. Entropy helps us understand the world and achieve great things. There is an underlying beauty in its principles that we can use to advance scientific discovery. When we understand the subtleties related to balancing surprise and structure, we increase our chances for effective collaboration and finding novel solutions to complex problems.

This is a classic migration case study (the past, current and the future) at scale from a world-wide company transitioning from Confluent Platform and Confluent Cloud to self-managed Apache Kafka on Kubernetes using Strimzi. At Maersk, we have been architecting, designing and implementing our 3rd generation Event Streaming Platform. This platform is based on Kubernetes in Azure and using Strimzi to operate Apache Kafka at large scale, highly reliable, segregating data based on isolated use cases. Our 2nd generation was based on OnPrem Confluent Platform and Confluent Cloud and this presentation is the story of this migration and reasoning behind it. Furthermore, we would get into details on how we monitor (Grafana, Prometheus), alert (GoAlert and alert as code), operate and provide self-service solutions on top of Strimzi to enable business critical application in Maersk, implemented in GoLang using the GitOps deployment model with Flux and Kustomization among others. Finally, if time allows we will end with a demo of an open-source self service tool to monitor and explore the cluster with most wanted features such as topic message browsing and configuring and restarting connectors.
