It's hard to imagine a modern developer workflow without a sufficiently advanced build system: Make, Gradle, Maven, Rake, and many others. In this talk, we'll discuss the evolution of build systems that leads to distributed build systems. Then, we'll dive into how we can build a scalable system that is fast and resilient, with examples from Google. We'll conclude with the discussion of general challenges of migrating systems from one architecture to another.

Most people will claim that this never happens, others hope it never happens, but it happened on March 10, 2021, and it was not just the 1 datacenter that got impacted, but the whole campus of the provider that got powered down. This talk will explain how our customers survived this outage, how our culture, opensource tooling and automation saved the da(y,ta). A talk about disaster recovery, business continuity plans and building cloud agnostic stacks that survive disasters.

At Systematic we are using Groovy technologies to build a fairly standard 4-tier Java web application for a customer. This lecture describes our experience. We will tell you about the choices we made, how we built up knowledge about Groovy, what our biggest mistake was, and how we dealt with it. We used Grails for the user interface, pure Groovy for implementing web services, Geb for automating tests of the user interface, and Spock for automated tests in general. We will tell you where these technologies provided great benefits, and where they were the source of trouble and frustration. This lecture does not presuppose deep knowledge about Grails and Groovy. It should be of interest to any professional software developer who is considering replacing Java with Grails and Groovy. Systematic A/S is a Danish software house headquartered in Århus. We employ about 450 people in 7 nations. We provide solutions for the defence, healthcare and public sector.

You've probably heard of PhoneGap, the free, open source framework for creating mobile apps using standard web programming, but maybe you're skeptical. You probably have a lot of questions. How easy is it to create an app with PhoneGap? Can I convert my web site to a mobile app? Will the app be too slow to use? In the session I will, with nothing up my sleeves, convert a mobile web site into a PhoneGap app for both iOS and Android. I will take advantage of both device and HTML5 features. I will show solutions to the performance challenges PhoneGap apps sometimes suffer from. I will show to structure your web site to make it easy to convert to a device app.

Writing applications for phones has been a daunting task since every platform uses it's own language and API's. PhoneGap will solve this problem for you by utilizing the browser capabilities. In this session we will see how we can turn a web based application into a native app. We will also look at posibilites to integrate native functionality, like the camera or accelerometer, in our application. The final part of the presentation is about deployment of these applications. Adobe offers a cloud based service called PhoneGap Build which easily builds your application for all platforms.

The paper explains how you can write an interpreter and get an optimizing just-in-time (JIT) compiler for free. This enables language designers to focus on features without worrying about the complexities of compiler optimizations and code generation. This paper presents a Java Virtual Machine (JVM) that allows the application to control the JIT compiler behavior at runtime. We'll discuss how various programming languages can take advantage of this framework. To intrigue compiler aficionados, the authors show how combining AST node rewriting during interpretation, optimization, and deoptimization produces high performance code from the interpreter without a language-specific compiler. In addition, they present how features of a variety of programming languages, such as JavaScript, Ruby, Python, R and others, map on the framework.

Abstract: Behavior driven development (BDD) is an agile method that (among others) puts the ideas of agile testing into practice. BDD emphasizes collaboration between testers, developers and the business stakeholders and help preventing bugs by introducing testers and testing concept into the specification phase. This is all fine when you start with a new, green field project. But what about those old legacy applications that have no proper automated test coverage and even if there are automated tests no one is dare to touch them? Is it possible to introduce BDD for these projects? What are the different strategies, collaboration and testing patterns that can be followed? This session gives a brief overview about what BDD is today and addresses these questions. The code examples use .NET and SpecFlow, but can be easily adapted to any other platform too.

Do you remember your childhood when your mom or an older story teller pronounced the most interesting words in the world? “Once upon a time…” Let me be now your story teller, listen to my story about a legacy app, a painful problem, the search for the solution and the lucky outcome. No, no, this is not the story about a new green field project where everything is so clear. However, even in this story there is a master builder, who shows the developers how to scaffold the legacy app with BDD scenarios using SpecFlow or Cucumber and everything will be all right in the end. Let me tell you about different strategies, collaboration and testing patterns that can be followed in such a renovation-like situation. So, are you ready?... “Once upon a time there was a company where…” To be continued at my session

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.

When you’re building (micro)services, you have lots of framework options. Spring Boot is no doubt a popular choice. But there’s more! Take Quarkus, a framework that’s considered the rising star for Kubernetes-native Java. It always depends on what's best for your situation, but how to choose the best solution if you're comparing 2 frameworks? Both Spring Boot and Quarkus have their positives and negatives. Let us compare the two by live coding a couple of common use cases in Spring Boot and Quarkus. After this talk, you’ll be ready to get started with Quarkus yourself, and know when to select Quarkus or Spring Boot.

Six Myths about Ontologies: The Basics of Formal Ontology

johnbeverley2021

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.
