Function components on React introduced hooks, a completely different approach to how you deal with the component lifecycle. This has led to many discussions on when and where to use hooks.What values should be memoized with useMemo? When is needed useCallback? What should go in the dependency array? Why using useReducer if it does the same as useState? This talk tries to give a swallow look at the trade-offs of using different callbacks and advice on when to use them, with practical examples.

More often than not, modern and powerful software will at some point have to deal with processing a large amount of events and data. 100 incoming requests per minute can suddenly turn into thousands or more per minute. Appropriately sized hardware can deal with heavy load, if it is available. Well written software intelligently utilizes the available resources, such as memory, network, threads, etc.The JVM left a lot to be desired here. Especially when it came to managing a limited number of threads. They were an expensive commodity and concurrency is always difficult to implement. Reactive frameworks such as WebFlux, RxJava or Kotlin's coroutines closed this gap. However, these frameworks are cumbersome. They take some time to really master.But Project Loom, introduced with Java 21, offers virtual threads as a native Java feature to solve this problem. I will show how the new Java features compare to established reactive ways. Do they mean the end for reactive programming?

In this talk, we will explore how WebAssembly (Wasm) is poised to become a major player in the future of cloud computing. Wasm is a binary format that can be compiled from many different languages and run on a variety of operating systems and architectures. Its near-native performance, portability, and security make it an ideal solution for addressing the challenges of distributed application development, deployment, and maintenance.One of the fastest-growing Cloud Native trends is the adoption of Wasm, with projects such as Docker+Wasm launched with a partnership between Docker and the CNCF’s Wasm runtime WasmEdge. Wasm's efficiency and speed make it ideal for on-demand scaling, while its sandboxed environment and deny-by-default approach to granting access to capabilities provide enhanced safety and security.We will delve into the key value propositions offered by Wasm and how it can help address the challenges posed by the new cloud era, including security concerns.

In the fast-paced realm of modern web development, there's an alarming trend: the sidelining of security. As we become more dependent on comprehensive frameworks, there's a growing assumption that these tools are impenetrable fortresses against increasingly innovative attackers. This complacency can be costly. In this presentation, we will delve deep into the world of current web vulnerabilities, specifically focusing on modern front-end applications.You'll be equipped with a clear understanding of these risks and the best strategies to proactively counteract and combat them, ensuring a safer web environment for all users.

Cultivating an entrepreneurial mindset is very often the differentiating factor between success and stagnation.

What sets entrepreneurial mindset apart is its potential to bring about positive change not only in one's own life but also for the world. The best part? Entrepreneurial mindset is something anyone can cultivate if they set their mind to it. Join the session to get inspired and learn practical tips on how to get started!

In modern frontend development, things are changing a lot, and the line between pure frontend and backend work is blurry. React Server Components make it tricky to decide if they belong to the frontend or backend because they have the word "server" in them. On the other hand, Server-Side Rendering (SSR) also has "server" in its name but has been seen as a frontend tool. So, it's a bit confusing.Starting a new project can be even harder when you don't fully understand the basics of your tools. That's why it's a good idea to go back to the basics and consider building new applications using server components and clean architecture.In this presentation, we'll dive into the core ideas of server components and look at how Vercel does it in Next.js. We'll also explore the option of using a clean architecture to start building applications in this new way.

Component Driven Development focuses on building your UIs by starting with the individual components to then compose later into your pages. Let’s dig into how we can utilise Storybook to promote this paradigm, in the environment of large web apps that many of us work with daily. I’ll take you on a journey from component creation, discussing best practices for API design, how to then write Stories to document your flexible component API and then compose those stories directly in your tests with React Testing Library to encourage UI driven testing. These are usually best practices we associate with traditional component libraries but complex web apps have a lot to learn from adopting this approach in setting them up for success.

Developer teams are encouraged to solve basic functions centrally and transparently to save effort in repetitive tasks. One such approach is the use of the Mirror Pattern (bracha.org/mirrors.pdf).Initially, this presentation introduces the fundamentals of the Mirror Pattern. It discusses how a minimal Mirror Pattern can be established in a Java project and the prerequisites needed. The pattern is theoretically motivated and then demonstrated through a minimal reference implementation. Based on the example implementation, potential application areas are explored with examples, focusing on enhancing object orientation. Meta-programming via the Mirror can help reduce procedural code (often found in Spring applications) and enable developers to create intuitive, structured, and more reusable structures. Since there are no silver bullets, risks and experiences from over two years of practical use in projects are also considered.

Developers are like mechanics: we need a good set of tools to do our job. But reality is often dissapointing - cryptic CLI tools, confusing configuration files and dreadful docs are everywhere.What if we could do better? Using IDE extensions, you can greatly improve your tools’ developer experience - and it’s not as scary as it seems!Are you trying to optimize the DX of a framework used by millions? Are you just trying to make your team’s life a little bit easier? Either way, I will show you how you can rapidly go from idea to a working VSCode extension and solve real-world problems.

Testcontainers has become one of the most popular tools for software integration testing. If you can put your system-under-test into a container, Docker compose cluster or a pod, this is what you're likely to use. If your target isn't ready, not containerizable or just too heavy for testing as is, you can always use mock testing frameworks, e.g. WireMock or MockServer in the JVM ecosystem. Can you combine both approaches? Sure! In this talk, we will classify integration testing and discuss areas for WireMock and Testcontainers, and discuss which tool to choose for each use-case. And why not both? We will discuss putting WireMock into Testcontainers, and getting best from them thanks to the new WireMock modules for Testcontainers. Last but not least, we will see how to put WireMock in front of the Testcontainers or your real system to do deeper tests or even chaos engineering. P.S: We will focus on the Java, Golang or Python examples, but the same approaches can be used everywhere

RxJS has a flexible implementation comparing e.g. to RxJava, separating the operators from the observable object itself. This allows other developers to create their own operators and even publish them as third-party libraries. This is the case e.g. for the RxJSx library containing operators for dealing with arrays and tuples.In this talk, we will introduce the RxJS operators ecosystem, draw some examples from RxJSx to showcase how to use operators from a third-party library, and finally showcase how one can create their own operators.

Version 1.0 of Dart was released back in November 2013. Since then, it has always been very quiet around this language and it never really became successful. But now that Dart is the programming language behind the more than successful cross-platform framework Flutter, it is gaining more and more popularity.Dart comes with some very interesting and unique features. For instance, it is possible to compile not only "just in time" (JIT) and "ahead of time" (AOT) but also Dart code to Java Script.Using various examples and live coding, I will give you an insight into the programming language Dart and show you different features.Let me take you into the world of Dart and get inspired!

For the past two years, reports on emerging technologies have shown a strong evolution toward composable architectures. A best-in-class composable architecture, cloud-based, consists of a set of reusable building blocks. These blocks can be custom-developed or built with the best in the market off-the-shelf SaaS blocks. A composable architecture pushes the boundaries of micro-services, allowing for greater agility, faster implementation, and improved user experience through strong modularity. But all those benefits are real only if your implementation is done the right way.

Tree shaking is a feature that is used by modern bundlers to keep bundle size down (and load times fast), but if just one import is written in a non-optimal way, this can result in the whole dependency being included in the bundle. In some cases, this even happens with automatically suggested imports by the IDE. Learn about the correct way of importing from dependencies, tricks you can use to easily determine the impact on bundle size, and why having a lot of dependencies may not be as bad as you think!

There were a lot of onboarding challenges, professional and personal, but we successfully integrated 15+ nationalities into our engineering organization.

I share a novel framework called MM Life Circles, which allow teams to visualize and manage the entire lifecycle of generative AI models, from research to deployment including best practices for handover between each phase.So essentially, I start with choosing a generative AI model as an example, then cover the data side of it followed by training frameworks.- Comprises of research platforms such as Python, R studio and associated libraries- Covers model building and tuning frameworks such as [Pytorch Lightning](https://www.pytorchlightning.ai/index.html), [Weights & Biases](https://wandb.ai/site), [mlflow](https://github.com/mlflow/mlflow) etc.- Benchmarking & Optimization Tools such as [onnx](https://onnx.ai/), [tensorflow](https://www.tensorflow.org/tensorboard), [tensorRT](https://developer.nvidia.com/tensorrt) optimization

In this session, I will highlight one of the most reliable and efficient ways of software development for companies and teams of any size regardless of their architecture, technology stacks, and frameworks.Have you ever used Ruby on Rails with its scaffolding system? Or maybe Laravel with its own code generator? There is always something that helps you to write less code - nuxi, go-swagger, Hygen, and many others... but does it really?Everybody knows "code-first" or "design-first" and even the "specification-first" approaches when we talk about microservices and APIs, but what if we can expand it to the whole system not only for service communication, let's dive in!We will be focused on how specifications and proper code generation can help engineers with:- reducing the risks of bugs and misconfiguration, - designing applications regardless of framework tool limitations,- writing less boilerplate code.Finally, and most importantly - how to start using this approach today.

Step into a world where IoT and AI are not just buzzwords, but catalysts of extraordinary innovations implemented in the most unexpected places.

Statistically 70% of all IT-projects worldwide cannot be classified as "successful". Did you know that? And the crazy thing is that this figure has remained unchanged for the past 20 years, despite the fact that technology is constantly improving. The reasons: poor communication, changing requirements, unrealistic expectations and much more. Hardly any of these reasons have anything to do with technology, as it is essentially down to a lack of soft skills. Paradoxically, too much focus on technology leads to poorer results and also has another side effect: A lack of soft skills is also the main reason for job frustration, as 94% of HR managers say that employees with stronger soft skills are more likely to be promoted than employees with more years of experience but weaker soft skills. Sounds familiar?Pierluigi is the CEO of Utterskills, an e-learning academy for soft skills in IT and in his talk he will give some quick wins and an overview of the most important soft skills in IT.

How microservices become autonomous services.Microservices have been used more and more frequently in recent years. The use of many smaller services has made the use of synchronous communication increasingly difficult and complex.This is because synchronous communication ensures close coupling between the individual services and can ensure that if one service fails, a number of others fail at the same time.Typical resilience patterns such as: Circuit-Breaker, Retries, Service Meshes, etc. in turn increase the complexity of the overall system and also only partially solve the real problem. In this presentation, I will show how an event-first mindset can be used to design entire systems in an event-driven way.How microservices become autonomous services that are completely separate from each other and only communicate with each other via events.And how developers can use serverless and FaaS to focus on what is important: delivering business value.

Ever wondered what happens after you type docker run? Or did you know you can docker exec into a container without docker? We will try that in the talk using only native Linux commands! I will dive into the crucial parts of containers like groups, namespaces, and virtual ethernet bridges. Don’t have an idea what these things are? Then my talk is perfect for you! These are the low-level build blocks of what we know as a container. After this talk, you will have a whole different understanding of containers and why they aren’t even that special (even though they are pretty cool).

Beware of the faith healer! Everything in life is a trade-off. This applies particularly to every decision you take on technology and software architecture. You want to be cautious when a faith healer enters the scene and promises that a certain technology, tool, or methodology solves every problem and removes all pain from you. At the end of the day, there is no silver bullet in software architecture.Does this and more life hacks that are relevant for every software architect raise your interest? Things that are super obvious, but are still often disgracefully neglected in the field? Why don't you join this talk and join a journey through this extremely incomplete Lifehacker's Guide to Software Architecture?

A significant amount of Engineering and Product departments feel overwhelmed by business needs, and they look at business growth as something that is preventing them to improve on their architectures and processes. I believe, and will demonstrate with real world data, that this is not true, and that it can and should be reverted.Through the tracking and analysis of the correct Business, Product and Engineering metrics, and by correlating them, Product and Engineering leadership can create a compelling story that will help their business grow tremendously. Once the proper framework is in place these executives will have the necessary tools to change the narrative with their teams and the board room.I will share a decade of learnings in a fast growing SaaS startup, that enabled my company to sustain its high level of growth for the last 10 years, grow its Engineering team from 5 to 150 staff, while reaching industry leading NPS and CSAT scores without raising any outside capital.

Continuous Integration and Continuous Deployment/Delivery has become an integral part of our daily workflow.

Development in the Manufacturing & Industry sector is hardware-oriented and driven by industrial standards. Engineers are usually responsible and there are quality management specifications.However, the proportion of software development has increased in recent years in the Manufacturing & Industry. In addition, the requirements of digitalization / Industry 4.0 are creating new requirements in the industrial environment. The automation pyramid is being "broken up" and technologies such as MQTT, REST or OPCUA are accessing data in order to supply use cases such as IIoT, BI or artificial intelligence with information.This creates new challenges for collaboration in modern manufacturing and industry projects. In this talk, I would like to present these challenges and possible solutions for software developers and engineers to work better together.

In the dynamic landscape of developer experience, documentation often takes a back seat, relegated to a role of retrospective record-keeping. This talk challenges the status quo by advocating for Documentation-Driven Development (DDD) as a pivotal, proactive force shaping the very essence of developer experience.As a developer who spent years creating abstractions used by other developers, I’ve found that the best time for documentation isn’t after code implementation. In this talk, we explore the continuous nature of documentation, presenting it as an ongoing dialogue rather than a static artifact.Discover how embracing Documentation-Driven Development cultivates a richer, more cohesive, and ultimately more satisfying developer experience.Using a real world example, we explore how an abstraction used everyday by developers in Factorial, was built and is still maintained and improved easily, thanks to DDD.

A Large Language Model (LLM) is a component of artificial intelligence specifically designed to comprehend and generate text that closely resembles human language based on the input it receives. One common scenario where it finds utility is when it needs to generate Java code to address a problem or create Kubernetes manifests with specific features.However, LLMs can also be employed with your enterprise code to enhance the customer experience, eliminating the need for customers to navigate through an entire website or improving the search process of on-site documentation During this session, we will explore how to integrate Quarkus with Large Language Models to establish a novel interaction interface for your users so they feel more human than just clicking across links.If you're interested in hands-on experience with Large Language Models and Java, with a focus on practical applications rather than theory, then this session is for you.

Remember the good old days when we used UML diagrams to model our systems? Well, times have changed. Agile, SDL, TDD, and other cool stuff have given our code superpowers. And code is the new model these daysBut code is not just for writing software. Code can also define and manage everything else in our IT environment, from infrastructure and configuration to security and workflow. This is the idea behind “Everything as Code” (EaC), a new trend that is taking DevOps by storm.While you may have heard of Terraform and ArgoCD, there's a new trend expanding into DevSecOps, workflows, and beyond. Join me in this talk to discover over a dozen cutting-edge "as code" concepts, inspired by the pioneering work of Patrick Debois, the creator of the DevOps concept. These concepts range from Compliance, DataOps, Documentation, to even Slides as Code!Through live demos and discussions, learn how these trends revolutionize development, fostering collaboration and efficiency

Let's talk about the elephant in the room: testing in software development isn't always a crowd favorite. But what if it didn't have to be that way?This session is all about cracking the code to make testing not just bearable but actually kinda cool. No, seriously. It's not just another snooze-inducing session on testing. We're unpacking practical tips and clever techniques (such as risk-based testing and property-based testing) to make testing more interesting, efficient and less of a time sink. Join us and learn about (test design) techniques that'll turn testing into a secret weapon in your software development toolkit. Finally you will know how to answer the question “What should I (not) test?!”…. It's time to be more effective and starting doing more with less—less time testing, more time building awesome stuff!

A developer and a platform engineer walk into a bar. What follows is a deep discussion: During the developer platform hype, are we losing sight of what is really important? What is developer productivity, how can we measure it, and how can we improve it without boiling the ocean? Developer platforms are getting a lot of hype. But that’s just something big companies do, and it means setting up a huge Kubernetes cluster and deploying Backstage. Right? Wrong! Actually, it is all about improving developer productivity, and that is important for a single developer, or a company with tens of thousands of IT professionals. It also means that the tools, services and artefacts needed to boost productivity can be widely different, and there is no default solution. In this talk, we will discuss the latest research on how you can measure and improve Developer Productivity. Then, we will look at actual tools and methods that make you more productive as an individual, a team or a whole company.

Distributed SQL Databases are a powerful new data management technology that addresses modern applications’ need for scalability, availability, geographic distribution, and low response time – with the power of SQL and strong consistency. However, distributed databases bring their own challenges. For example, the familiar trade-offs between consistency, high availability, and partition tolerance still exist. Remote data access will still incur speed-of-light network delays.This talk will describe the inner workings of distributed databases and how to design applications to best exploit their power. Using Oracle and other distributed databases as examples, we will explore the capabilities and unique application challenges posed by distributed databases. This talk will address design patterns that empower applications to handle network latency and consistency in the presence of real-world networks that can and do fail.

When building cloud applications, we should always bear in mind that our services are exposed on the Internet and can be accessed by anyone and may have untrusted users.Because of this, we need to be proactive and aware of these possible security threats so that we can design our cloud applications to be able to handle them properly. Apart from preventing malicious attacks, cloud applications must also be designed to protect sensitive data and grant access for certain resources to only authorized users. In this session, I will be talking about 3 security patterns that can be used to prevent malicious or accidental actions outside of the applications designed usage, and to prevent disclosure or loss of information when building for the cloud.

AI is on the rise and will, inevitably, help developers to be more efficient.But it is not only developers who benefit from these tools; it's hackers too. AI doesn't care if you are a defender or an attacker. This means bad actors can leverage the amazing capabilities of AI tools to write exploit code – even if they are not full-stack developers or penetration testers. This is concerning and underscores why code security is critical for the safety of society and organisations.When used responsibly, AI can help solve the greatest obstacle to successful software security programs: the imbalance that exists between the effort developers spend finding flaws and the time to fix them.In this session, we will write an exploit for a few publicly know vulnerabilities and demonstrate how AI can help prevent 'bad' code from becoming a bigger issue. Attendees will come away with in-depth information on the security implications of AI-assisted coding.

Witness how serverless transforms high-traffic challenges into seamless, cost-effective solutions at Amazon.com. We debunk myths about serverless and dive deep into how IMDB serves 800.000 requests an hour with AWS Lambda.Amazon.com launched in 1995 with a modest architecture and a grand vision to be Earth’s most customer-centric company. Learn how Amazon.com got big fast, and see their evolution from a monolithic architecture to a massively scalable system based on service-oriented architecture and microservices. We will dive deep into the architecture of IMDb and AWS Lambda scales to serve workloads at Amazon.com scale.

RESTful APIs have long been widely-used in web services, but developers have an overwhelming number of alternatives to consider, such as GraphQL, gRPC, event-driven, and asynchronous APIs. And more teams are shifting towards multi-protocol tech stacks. What are the benefits and technical limitations of each when designing a new system or adapting an existing one? This talk covers the evolving landscape of API protocols in 2024 so you can make informed architectural decisions to build robust, efficient, and maintainable APIs.

You write unit tests in your team? Of course you do! But are those tests sufficient? Coverage tools provide an answer. Unfortunately, coverage analysis is often insufficient. Even test suites with 100% code coverage often miss bugs. Some test suites bring only little added value in practice.With Mutation Testing you can check the quality of your tests yourself! Stryker puts your tests to the test. You get a more realistic statement, how well your suite can actually find errors and learn how to improve it. The tool integrates into your project and pipeline with little effort and gets results fast!Learning Objectives:* Understand why 100% coverage means little* Integrate Stryker into your own projects* Improve test suites with the help of mutation reports

Navigating the tumultuous waters of product and engineering since the 1990s, I've witnessed the dawn of early web technologies and the transformative evolution that followed. This journey, punctuated by both successes and setbacks, has endowed me with a unique perspective on the inevitable rollercoaster of product development. In this talk, we will delve deep into the invaluable lessons derived from product failures. Drawing parallels from the nascent days of the commercial internet to today's sophisticated landscape, I'll share personal anecdotes, insights, and strategies that will empower attendees to transform setbacks into stepping stones. By embracing the teachings of past missteps, we can pave the way for future innovations, ensuring that our products not only thrive but also reshape the horizon of possibilities.

Several studies shown that round 80% of our applications consist of other people's code. With using any 3rd party package (e.g. NPM, Maven, Cargo, NuGet, PyPi) that is developed by others, we also put a lot of trust in it, which might result in bigger security problems later. Would it not be nice if there is a better way to review a package for security? An easier way to perform an assessment based on certain aspects of the package that will tell you more about the package its software security. With the introduction of Scorecard project the Open Source Security Foundation (OpenSSF) exactly tries to achieve that. In this session we start out with different area's covered by of OpenSSF Scorecard, like how well it's maintained, does the build have dangerous workflows, and does the project use other security tools to check for problems?. All combined will give us the ability to assess a 3rd party package its security posture more easily and improve our own application security.

Get ready to dive into creating an AI-powered app using the OpenAI API. This hands-on session starts with a deep dive into OpenAI's API, showcasing its pivotal role in AI application advancements. We'll then explore Rust, showcasing its potential as a programming language in AI software development. Docker comes next, revealing how it transforms efficiency and scalability in our build. The crux of this session is not just about theory – it's about bringing these technologies together in a cohesive, powerful architecture. Attendees will witness first-hand the impressive synergy between OpenAI's API, Rust's robust coding capabilities, and Docker's flexible deployment methods. This is a practical guide to crafting cutting-edge, effective AI applications.

You've probably seen how to create a Function-as-a-Service with one of the cloud providers, but if this is all you know about Serverless, prepare to have your mind blown!In this session we'll show you how to create a production-grade, cloud-agnostic, event-driven serverless solution with Quarkus, a Java stack optimized for fast startup and small footprint; and Knative, an open source community project for deploying, running and managing serverless applications on Kubernetes. Say goodbye to vendor lock-in and hello to Supersonic Subatomic Java-based Serverless bliss!

Hibernate is the defacto standard persistence for Java database apps. It was built when Java apps and database systems were monoliths. The cloud, microservices and serverless have changed Java dramatically, but persistence is still the same. Now AI is making its way into Java and AI requires uncompromising performance. EclipseStore was built to be the Java persistence for the cloud and AI. It enables databaseless in-memory data processing by using Core Java only. While databases use database-specific data structures or formats, EclipseStore supports the real Java object model. The engine enables seamlessly mirroring any Java object graph of any size and complexity into any object storage such as AWS S3. This leads to 3 main benefits: 1) highest performance, microsecond response and query time, up to 1000x faster than comparable SQL queries,2) 96% cloud database cost savings, 3) Radically simplicity, only one data model, no expensive mappings or data conversion.

If you ever worked in a professional software project, you had someone taking care of UI/UX in your team. Ideally it was a dedicated role. If not, let me guess: It was this frontend folk!Those frontend people create the UI, what should you as a Backend Developer do for UX?In our talk we take you by the hand and walk you through the whole Software development process.Starting with the design phase in which you should already consider the potential user flow and processes when planning your architecture. While implementing your application you may want to provide a fast-responding API and prepare for future tracing after release.After Go-Live there are a lot of things negatively impacting your applications UX like high response times or even downtimes of a service you might want to detect and recover before the user even knows. Together we’ll find out where you can have an impact on the user experience of your project!

Scaling agile methods to large tech organizations doesn’t come naturally. While established frameworks like Nexus, Scrum@Scale or SAFe provide methods and processes to scale agile, they often feel clumsy, bureaucratic, and – actually – unagile. Recent approaches, such as Team Topologies and the unFIX patterns offer a different take on the problem. In our talk, we share firsthand insights on shaping an organizational structure that scales agile practices as well as our struggles and learnings along the way. We will guide you through our thinking processes and show how and why we arrived at our current organizational structure, which allows us to build successful products in a fast and user-centric way while ensuring sustainable employee satisfaction.

This talk explores the rapidly evolving landscape of modern data architectures that build and used for analytics purposes. They continually adapt practices and tools from software engineering. We will explore the growing influence of software engineering within the data ecosystem. Speaking of software engineering: the integration of analytics systems with the transactional/operative systems will also be taken into account. Typical scenarios and contextual factors of different architectural approaches we will also be discussed. We take a look into recent developments such as Data Mesh and Data Lakehouse, the ELT pattern, Cloud DWHs and theirlike. Additionally, I provide insights into the practical implementation of these architectures using tools and technologies commonly found in the “Modern Data Stack.”

When a system has "grown historically," this often applies to the tests as well: they run for too long but find too few bugs. The reason is that such test suites often test too much and too little at the same time. They test too much because they include tests that incur costs but provide little added value compared to similar tests. They test too little because important functionality remains untested.In the talk, I will present analyses mine data from your repos (version control, issue tracker, test coverage etc) to uncover these issues: Pareto optimization of test suites and test impact analysis identify the tests that currently have the best cost-benefit ratio. Test gap analysis reveals which code changes are still untested, indicating missing tests. By doing so, these analyses provide us as developers with effective tools to understand and improve our test architecture. For each analysis, I outline its research background and show practical examples from large systems.

The dream of communicating with computers using natural language has been around for almost half a century. Voice user interfaces (VUIs) are already available in the consumer sector through Alexa or Siri.This talk will examine how web applications can be expanded to include a voice interface consisting of speech synthesis and recognition based on current best practices from science for VUI. An example application will be used to demonstrate the existing possibilities.A particular concern of this talk is to address the limitations of the current W3C standard WebSpeech API. The non-functional requirements of availability on different system environments, data security and offline capability will be analysed in more detail. The source code and documentation of Webkit, Chromium and the Gecko engine are included in this analysis. Finally, an outlook is given on the challenges for VUIs on the web for the next decade.

While seasonal trends dominate not only the fashion world but also the IT industry, let's consider whether our projects are built on a solid foundation or on fashionable, fleeting solutions. In this presentation, we will delve into Hype Driven Development: its enticing promises, pitfalls, and how to find the golden mean between innovation and a safe choice. You will learn where the hype comes from, its stages, and the potentially disastrous consequences it can have. I'll guide you on how to follow trends without losing sight of the main goal - the functionality and success of the project.

In this case study, I will guide you through the implementation project of an AI-driven optimisation tool in the production chain of a large German manufacturer. I was part of a team made up of IT strategy and global AI executives. Together we worked through a variety of challenges that can occur in a company with over 200,000 employees.The initial situation was characterised by a lack of clear strategic direction and a culture of experimentation. One of the biggest obstacles was the lack of a data strategy, coupled with reluctant management and the unwillingness of various areas of the organisation to provide necessary data. In this talk, I will discuss why a team of data scientists and machine learning engineers alone is not enough. I will highlight the various organisational obstacles that can arise and how to overcome them. The talk will also emphasise the importance of a structured organisation and a comprehensive strategic approach to AI.

Progressive Delivery makes it easier to adopt Continuous Delivery, by deploying new versions to a subset of users before rolling them to the totality of the users, and rolling them back if not matching some key metrics, using techniques like feature flags and canary deployments.For workloads running on Kubernetes it is very easy to adopt Progressive Delivery using Argo Rollouts. At Adobe Experience Manager we deploy over 10k customer services to Kubernetes. Changes can occur multiple times per day both internal and from code. A new feature can work fine for 99% of customers but still affect the other 1%, and detecting this just from tests is costly.We will show how to implement a Progressive Delivery pipeline with Argo Rollouts to improve the reliability of the service and prevent regressions. It allows the protection of the service and automation of roll backs to a previous version if needed. This allows for faster delivery with more confidence.

When we talk about leadership, we say that leaders need to delegate, they need to empower people, they need to inspire and motivate those they lead. What we rarely talk about is the other side of leadership, the hard truths, how easy it is to say to delegate, how hard it is to actually do, how easy it is to say you need to inspire people, how hard it is to actually do, how easy it is to say you need to confront difficult situations, and yet how hard it is to actually do so.In this talk, we're going to examine what the consequences of not taking these actions are, and how by avoiding these problems, we not only are kicking the can down the road, but ending up potentially hurting more people than we ever intended to.

Developers love packages, and I don’t mean the type that come gift wrapped on holidays. Software packages provide a convenient way of sharing libraries, upgrading version, and validating the provenance and security of your dependencies. And this also applies to developing models for machine learning and generative AI applications. We will cover best practices for storing, versioning, and validating the models that you use to develop machine learning applications. Also, I will give a demo and example of an end-to-end flow that shows how you can pull open source models, version them, transform them, and deploy them securely, all from your favorite model development tools.

I make the case that investing deeply in relationships with real data will improve engineering throughput and can be objectively quantified. This session uses research from the DORA report and other studies to help technical folks understand that our job isn't simply to code but to build the relationships that enable us to write better code and solve problems. We will discuss the metrics, examples, and science behind relationship-driven development. The user will be armed with the tools to help others understand the concept.

What makes a team high performing and how do you achieve that? In this talk, I would like to share my own experience on a project where we have transferred the team from a state where they did 2 times deployment a month to 200 deployments a month. This includes understanding four key metrics, Continuous Integration and Continuous Delivery, creating safe development environments with automated testing and avoiding silos with sharing knowledge and pairing. Overall, the team is transformed to a high performance software development team.

Semi-supervised learning, an innovative approach in machine learning, strategically positions itself between the realms of supervised and unsupervised learning. This methodology uniquely utilizes a combination of a small portion of labeled data and a substantially larger set of unlabeled data for model training. Its significant advantage lies in scenarios where gathering a fully labeled dataset is prohibitively costly or logistically unfeasible. By blending the directive nature of labeled data with the extensive insights of unlabeled data, semi-supervised learning offers a practical, cost-effective solution for comprehensive model training, especially in data-scarce environments.

In this talk, I will take you through all the awesome new stuff you can find in Java. I’ll show you the actual usage of these new features so that you can use them in your project too. Come and see real-world usage for constructs like records, switch functions, sealed classes, pattern matching, virtual threads, structured concurrency, and scoped values. This is even more important if you consider that the upcoming releases of extremely popular and widely used frameworks such as Spring (v6) and Spring-Boot (v3) will use JDK17 as the minimum baseline for development, while Jakarta EE 11 targets Java 21. Don’t get left behind and let me show you how to use all the new language features from JDK15 up to JDK22.Think records, pattern matching, sealed classes, virtual threads, structured concurrency,scoped values, string templates,switch for pattern matching and unnamed variables.

As of late, a number of key people in the IT industry have voiced their concerns about Cloud costs. Cloud costs have been steadily rising, with the basic experience being offered by the likes of Amazon and Google not changing much, if at all. We've decided to test out a migration of a part of our applications to a bare metal machine (physical DELL rack units of our own), set up completely by ourselves, from scratch. From kubernetes, CI/CD pipelines, disk redundancy, to docker registry, Github Actions, etc.We've now been running this set up for about 60 of our applications and have seen a 80% decrease in costs, with the bare metal and data center costs being redeemed within just 2 months of leaving the Cloud (Amazon specifically).We'd love to share our journey of our bare metal migration!

Are you overwhelmed by the velocity and amount of information you have to process on a daily basis? Do you struggle to remember or pay attention to the right things? Do you find yourself procrastinating on important tasks that should be easy to do? You're not alone. In fact, these problems are common for tech workers because our jobs depend on our abilities to learn, adapt, and ignore the noise. As someone with attention-deficit disorder (ADD) working in tech, I have learned my lessons the hard way. I want to share them so you don't have to. Struggling with attention is a spectrum, not a binary, and this talk is meant to be helpful whether you have ADD or not. I will dive into the biological and psychological theory - the "why" - behind problems with attention and focus so you know what you're up against. Then, I will discuss some of the practices - the "how" - that people have come up with over the centuries to manage their focus and manage their personal knowledge.

When your application becomes more popular and receives more traffic, you can just add more stateless application server. But for the database, this is more complicated - scaling systems with state is always complex.Articles and blogs never explain the different approaches and their shortcomings of horizontal database scaling solutions reasonably - most often, they just try to "sell" a specific approach. But each of them has an impact on your application, and you need to build it with these constraints in mind. Covered in the talk will be:* Tasks to do before any scaling* Scaling-Up as a simple first approach* Multi-Master-Replication* Replication* Sharding

Quantum computing has been in and out of the news for quite some time now, with promises to break encryption and revolutionise AI, simulations and whole industries. However, for a major part of the public, and even most developers, it remains a bit of a mystery.
Let’s explore it together. What is quantum computing? What sets it apart from classical computing? What are some of the use cases that will transform our world? And, most importantly, what lies ahead in a future where quantum computing becomes accessible to developers of all backgrounds?
