They define semantics\, rules \, and guide developers on how to structure code to develop complex busine ss logic. However\, the implementation of those in Java usually leads to s ome technical challenges.In this workshop\, we look at different approache s and tools that support developers building rich domain models in Java: t he jMolecules library\, that allows expressing DDD concepts in code and th at provides integration with many ubiquitous technologies like Spring\, Ja ckson and various persistence technologies. For Spring Boot applications\, the Spring Modulith project supports developers to implement business mod ules\, the interaction among them using events\, their testability and doc umenting them.\nSpeakers: Oliver Drotbohm\nTrack: Architecture URL:https://vdt26.voxxeddays.ch/talk/tactical-domain-driven-design-with-jav a-spring/ LOCATION:ws1\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Architecture END:VEVENT BEGIN:VEVENT UID:cfp-1151-8689@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260205T080000Z DTEND:20260205T110000Z SUMMARY:No Pandas Were Harmed: Elegant and Efficient Data Analytics with Po lars DESCRIPTION:Data analytics doesn'\;t have to be slow or cumbersome. With Polars\, a next-generation DataFrame library built for performance and si mplicity\, you can process massive datasets faster than ever. In this hand s-on workshop\, you will discover how to leverage Polars to support your d ata workflows from the fundamentals to the more advanced analytics scenari os.In the first part of the workshop\, we will introduce Polars as the mod ern library for data analytics in Python\, covering its data model\, engin e design\, and how it compares to other analytics tools like Pandas\, whic h is effective for smaller datasets\, and Apache Spark\, which is horizont ally scalable but inefficient for smaller datasets because of the overhead of the distributed infrastructure. The second part will dive into a real- world dataset of NYC taxi trips\, containing hundreds of millions of rows. We will walk through efficient data ingestion and cleaning\, and then exp lore how to perform lightning-fast queries and groupings directly in a not ebook environment. You will also learn how to visualize your findings with simple yet powerful plotting techniques.Finally\, we will tackle more com plex and realistic analytics scenarios\, such as identifying the top-earni ng drivers over a specific time window\, and visualizing their most profit able trips and neighborhoods. Through these scenarios\, we will showcase h ow Polars empowers you to move seamlessly from raw data to meaningful insi ghts.\nSpeakers: Andrea Mocci\, Jesper Findahl\, Marco D'Ambros\nTrack: Da ta URL:https://vdt26.voxxeddays.ch/talk/no-pandas-were-harmed-elegant-and-effi cient-data-analytics-with-polars/ LOCATION:ws2\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Data END:VEVENT BEGIN:VEVENT UID:cfp-1151-8691@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260205T120000Z DTEND:20260205T150000Z SUMMARY:From LLM orchestration to autonomous agents: Agentic AI patterns wi th LangChain4j DESCRIPTION:The last few months have seen the rapid evolution of LLMs from passive completion engines\, only good for generic chatbots\, to component s of a more complex\, programmatically defined\, workflow and finally into active and autonomous elements capable of reasoning\, planning\, and taki ng actions.But moving from basic prompt engineering to truly autonomous sy stems requires a new class of design patterns and possibly a framework all owing to implement those patterns and put them at work in a convenient and effortless way.In this workshop\, we will explore the architecture and im plementation of agentic AI using LangChain4j\, a Java-native framework for building LLM-powered applications. You’ll learn how to move beyond the plain usage of a standalone LLM to design intelligent\, modular agents cap able of dynamic decision-making\, memory retention\, tool usage\, RAG\, MC P and A2A integration and multi-step goal execution.After having covered t he core concepts of agentic AI\, we will guide you in incrementally buildi ng and testing an agentic system from scratch using LangChain4j and Quarku s\, backed by real-world examples and live coding. Whether you'\;re exp loring agentic AI for task automation\, intelligent assistants\, or decisi on-support systems\, this session will give you the practical tools and ar chitectural understanding to build robust and maintainable autonomous agen ts in Java.\nSpeakers: Mario Fusco\, Kevin Dubois\nTrack: Machine Learning & AI URL:https://vdt26.voxxeddays.ch/talk/from-llm-orchestration-to-autonomous-a gents-agentic-ai-patterns-with-langchain4j/ LOCATION:ws3\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Machine Learning & AI END:VEVENT BEGIN:VEVENT UID:cfp-1151-8690@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260205T120000Z DTEND:20260205T150000Z SUMMARY:Maintaining legacy applications using AI tooling DESCRIPTION:This session will be focusing on building a working knowledge o f available AI tooling that can help developers be more productive in thei r day-to-day work\, with a focus on existing applications and their evolut ion (including old applications). We'\;ll be talking about techniques a nd methods to refactor and update your applications\, while keeping things manageable\, readable and to the level of code quality that is expected f rom an enterprise application.We'\;ll also be discussing the MCP protoc ol and how it can be used in order to supercharge your developer tooling e ven further. We'\;ll be exploring how to use existing resources in orde r to e.g. obtain better information for your design\, code implementation\ , API endpoints\, etc. Then we'\;ll also explore what it takes to build one of these servers in case you need to offer an MCP server to the rest of your colleagues.All of these topics will be introduced through short pr esentations\, then participants will have the option of working on illustr ative examples on their own.\nSpeakers: Cristian Schuszter\nTrack: Develop ment Practices URL:https://vdt26.voxxeddays.ch/talk/maintaining-legacy-applications-using- ai-tooling/ LOCATION:ws4\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Development Practices END:VEVENT BEGIN:VEVENT UID:cfp-1151-8651@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T080000Z DTEND:20260206T081500Z SUMMARY:Welcome DESCRIPTION:Welcome to the 11th edition of Voxxed Days Ticino.The biggest d eveloper conference in Ticino.\nSpeakers: Federico Yankelevich\, Tiziano L eidi\nTrack: People & Culture URL:https://vdt26.voxxeddays.ch/talk/welcome/ LOCATION:Room A\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:People & Culture END:VEVENT BEGIN:VEVENT UID:cfp-1151-8652@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T081500Z DTEND:20260206T090000Z SUMMARY:The Past\, Present and Future of Programming Languages DESCRIPTION:Programming languages are a halfway house between the metal and the mind\, a bridge between the world of circuits and the world of applic ations\, the engineered and the social. Programming languages are the medi um through which developers codify systems and fragments. In each programm ing language is embedded a philosophy (or many) of how to think about code \, how to organise thoughts\, how to design. Programming languages also de fine skillsets\, ecosystems\, jobs\, loyalties and communities.When we thi nk of software and technology we often think in terms of progress and rapi d change. Programming languages\, however\, typically move at a far slower pace. Mainstream languages are still embracing ideas that are decades old . Constructs that developers welcome as new to their language of choice ar e often older than the developers themselves. And over all this hangs the question\, what of the future? How will current trends\, from FOSS to LLMs \, shape programming languages and their use? In this talk\, we will take a tour of the past\, present and future of programming languages.\nSpeaker s: Kevlin Henney\nTrack: Mind the Geek URL:https://vdt26.voxxeddays.ch/talk/the-past-present-and-future-of-program ming-languages/ LOCATION:Room A\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Mind the Geek END:VEVENT BEGIN:VEVENT UID:cfp-1151-8653@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T092000Z DTEND:20260206T100500Z SUMMARY:What’s (new) with Spring Boot and Containers DESCRIPTION:Spring Boot keeps evolving to make containerized applications s impler\, faster and more efficient\, but many developers still use outdate d or suboptimal approaches. In this session\, we will explore what'\;s new in Spring Boot 3.x for building and running applications in containers . From optimized Dockerfiles and layered JARs to Buildpacks and GraalVM\, you will have a better overview about how to create smarter images. We wil l also cover how Spring Boot integrates seamlessly with Docker Compose\, T estcontainers and Kubernetes for local development\, testing and scaling. Expect live demos\, practical examples and tips to modernize your containe r workflow. Additionally we take a glimpse on the new Docker Model runner feature and it’s integration with Spring AI.Key takeaways:Understand the latest Spring Boot container optimizacionsLearn best practices for buildi ng efficient Docker imagesDiscover how to integrate Spring Boot with Compo se\, Testcontainers and KubernetesGet actionable insights for improving st artup time\, image size and CI/CD performanceTarget audience:Developers\, DevOps engineers and architects using Spring Boot who want to modernize th eir container strategy and get hands-on with the newest tools and integrat ions.\nSpeakers: Matthias Haeussler\, Eva Panadero\nTrack: Build & Deploy URL:https://vdt26.voxxeddays.ch/talk/what-s-new-with-spring-boot-and-contai ners/ LOCATION:Room A\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Build & Deploy END:VEVENT BEGIN:VEVENT UID:cfp-1151-8654@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T092000Z DTEND:20260206T100500Z SUMMARY:Securing RAG Pipelines with Fine Grained Authorization DESCRIPTION:Building enterprise-ready AI requires ensuring users can only a ugment prompts with data they'\;re authorized to access. Relationship-b ased access control (ReBAC) is particularly well-suited for fine-grained a uthorization in Retrieval-Augmented Generation (RAG) because it makes deci sions based on relationships between objects\, offering more precise contr ol compared to traditional models like RBAC and ABAC. This talk covers how ReBAC systems can safeguard sensitive data in RAG pipelines. We'\;ll s tart with why Authorization is critical for RAG pipelines\, and how Google Zanzibar achieves this with ReBAC. We'\;ll then illustrate how pre-fil tering vector database queries with a list of authorized object IDs can im prove efficiency &\; security. The talk will also include a demo implem enting fine-grained authorization for RAG using Pinecone\, Langchain\, Ope nAI\, and SpiceDB.\nSpeakers: Sohan Maheshwar\nTrack: Security URL:https://vdt26.voxxeddays.ch/talk/securing-rag-pipelines-with-fine-grain ed-authorization/ LOCATION:Room B1\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Security END:VEVENT BEGIN:VEVENT UID:cfp-1151-8655@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T092000Z DTEND:20260206T100500Z SUMMARY:Rethinking Full Stack Application Development with Kiro DESCRIPTION:In the age of AI\, developers are increasingly leveraging agent ic AI experiences to build their products. The boundaries between software engineering disciplines have become thinner than ever\, enabling teams to move from idea to production rapidly. With the release of Kiro\, develope rs can now build and edit their code as a spec\, interact with the in-IDE assistant\, and delegate complex tasks with confidence. In this talk\, we& #39\;ll explore how to maximize AI-guided development with Kiro and transf orm your development workflow.\nSpeakers: Alessandra Pasini\, Romain Jourd an\nTrack: Development Practices URL:https://vdt26.voxxeddays.ch/talk/rethinking-full-stack-application-deve lopment-with-kiro/ LOCATION:Room B3\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Development Practices END:VEVENT BEGIN:VEVENT UID:cfp-1151-8656@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T092000Z DTEND:20260206T100500Z SUMMARY:Distributed Systems - What Can Go Wrong and How to Get It Right DESCRIPTION:Building distributed systems is challenging due to their comple xity\, scale\, and unpredictability. Common strategies to increase perform ance and reliability are queues\, retries\, caches and more. But be aware! Naively implemented optimizations have often the very much opposite effec t to what you expect. While they can not only prevent your system from wor king they can even affect your recovery process\, which is even worse.In t his session we will explore why you cannot simply add a retry here\, a que ue there and have a highly performant and reliable system. We will dive de eper into how to properly implement mechanisms and patterns in distributed systems to reduce failures and make recovery as smooth as possible.\nSpea kers: Florian Mair\nTrack: Architecture URL:https://vdt26.voxxeddays.ch/talk/distributed-systems-what-can-go-wrong- and-how-to-get-it-right/ LOCATION:Room C\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Architecture END:VEVENT BEGIN:VEVENT UID:cfp-1151-8657@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T092000Z DTEND:20260206T100500Z SUMMARY:Friendly Borders: Graph algorithms reveal Eurovision voting pattern s DESCRIPTION:Graphs offer a powerful tool for uncovering relationships and h idden patterns between entities. This presentation provides an introductio n to graph theory\, and demonstrates how graphs are applied across various business domains - from social network analysis and recommendation system s to fraud detection and supply chain optimization. Through an overview of core concepts and algorithmic approaches\, the goal is to show how graphs can reveal underlying structures in complex systems.As a real-world case study\, the presentation focuses on Eurovision voting - an area long suspe cted of regional bias and neighbourly favoritism. Using graph-based analys is and community detection techniques\, we explore voting patterns between countries to better understand how geography\, history\, and politics inf luence the distribution of points. Through visualizations and data-driven insights\, the talk demonstrates how graph theory uncovers hidden alliance s and behavioral trends within the seemingly light-hearted spectacle of a music contest.\nSpeakers: Domagoj Marić\nTrack: Data URL:https://vdt26.voxxeddays.ch/talk/friendly-borders-graph-algorithms-reve al-eurovision-voting-patterns/ LOCATION:Room E\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Data END:VEVENT BEGIN:VEVENT UID:cfp-1151-8662@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T101500Z DTEND:20260206T110000Z SUMMARY:Domain-centric? Why Hexagonal and Onion Architecture Are Answers to The Wrong Question – And What To Ask Instead DESCRIPTION:To separate technical from domain code\, architectural approach es like Hexagonal or Onion Architecture are currently all the rage. Howeve r\, discussions about their semantic details and their mapping to the sour ce code structure of software projects are at least equally ubiquitous.How much abstraction and mapping between architectural concepts is needed? Is persistence metadata in the domain model heresy? Above all: what is the a ctual goal of the exercise\, and: does it have to be so complicated?We add ress these and other questions in a theoretical overview and by looking at concrete examples. We discuss the trade-offs of different approaches and how various tools and libraries help us to maintain the intended structura l integrity.\nSpeakers: Oliver Drotbohm\nTrack: Architecture URL:https://vdt26.voxxeddays.ch/talk/domain-centric-why-hexagonal-and-onion -architecture-are-answers-to-the-wrong-question-and-what-to-ask-instead/ LOCATION:Room A\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Architecture END:VEVENT BEGIN:VEVENT UID:cfp-1151-8661@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T101500Z DTEND:20260206T110000Z SUMMARY:Technical Enshittification: Why Everything in IT is Horrible Right Now and How to Fix It DESCRIPTION:Software is a mess. Everything feels bloated and sluggish. Bugs pile up. Updates break more than they fix. Even basic apps demand absurd amounts of computing power. And innovation? If you count shuffling UI elem ents or slapping a ChatGPT button onto everything\, sure.The problem isn ’t bad engineers. It’s that building software has turned into an obsta cle course. Every step—writing\, reviewing\, deploying—is buried under layers of tools\, approvals\, and abstractions. A simple change takes wee ks. We spend more time wrangling complexity than shipping code. No wonder quality is tanking\, and real progress feels nonexistent.So how did we get here? More importantly\, how do we stop making it worse? Fixing the Googl es and Metas of the world might be out of reach\, but your projects don’ t have to follow the same path. This talk is about cutting through the mes s—how AI\, smart tooling\, and better developer workflows can actually h elp instead of adding more noise.

Academic success often relies on clean dataset s\, controlled environments\, and benchmark metrics—but in the real worl d\, models face data drift\, latency constraints\, integration challenges\ , and the risk of wrong predictions directly impacting customers and busin ess processes.In this talk\, we share our journey of bringing fraud detect ion models from research into production at Swiss Post. We highlight the r ole of the shadow model approach\, where new models run in parallel with p roduction systems to safely validate performance on live traffic. You’ll learn how shadow testing helps measure robustness\, monitor data drift\, and align with business KPIs—without introducing operational risk.Attend ees will take away concrete practices for bridging the gap between academi c experimentation and real-world operations: how to design safe rollouts\, build monitoring pipelines\, and decide when a model is ready for prime t ime.\nSpeakers: Giovanni Degiorgi\nTrack: Data URL:https://vdt26.voxxeddays.ch/talk/from-shadows-to-spotlight-how-swiss-po st-performs-reliable-ml-deployment/ LOCATION:Room B3\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Data END:VEVENT BEGIN:VEVENT UID:cfp-1151-8658@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T101500Z DTEND:20260206T110000Z SUMMARY:The developer's guide to making money in the open-source galaxy DESCRIPTION:Do you also dream about the 4-hour workweek?

Here\, unfortunately\, security has been left once again as an aftertho ught. Ever since LLMs were given the possibility to interact with your com puter and environment via tool calls and MCP\, not much has been done abou t security. So\, how can we secure AI agent-based systems before we end up in a security nightmare?In this session for AI-\, security-\, and softwar e-engineers\, we shed some light on the security challenges of agentic AI systems and how to mitigate them. We show how the application of a permiss ion-based access control mechanism can encapsulate MCP servers that are ot herwise executed with full privileges.

DESCRIPTION:When a bug is fixed\, how can we make sure it will not be re-in troduced in the future?Of course\, through a proper regression test\, i.e. \, a test that fails in the presence of the bug and passes in its absence. However\, regression tests are frequently ommited by the developers\, who tend to submit the patch alone.How can AI automation help developers it th is scenario? We explore this question in depth by introducing our open-sou rce GitHub bot that is triggered when a pull request is opened\, and propo ses a test that is guaranteed to fail in the presence of the bug and pass in its absence.We use a combination of LLMs and traditional\, search-based testing techniques to achieve this goal.The bot is currently deployed in three Python repositories (Javascript and Rust will be soon also supported ) of the Mozilla corporation\, where it has already helped developers with their regression tests. We share interesting early insights and feedback from this deployment and invite more open-source developers to adopt the b ot and provide constructive feedback!\nSpeakers: Konstantinos Kitsios\, Al berto Bacchelli\nTrack: Machine Learning & AI URL:https://vdt26.voxxeddays.ch/talk/bug-fixed-now-what/ LOCATION:Room C\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Machine Learning & AI END:VEVENT BEGIN:VEVENT UID:cfp-1151-8670@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T121000Z DTEND:20260206T125500Z SUMMARY:Tracing Java's Hidden Performance Traps DESCRIPTION:Painful days spent optimizing the wrong part of a flow.

Without structure\, they can jump into implementation\, miss requireme nts\, or generate code you can’t easily track. Spec-driven development i s a practical approach that brings order to this process.The method is sim ple: start with clear\, high-level requirements\, refine them into a detai led development plan\, then break that plan into a task list with trackabl e steps. The AI agent works from these artifacts—requirements.md\, plan. md\, and tasks.md—instead of ad-hoc prompts. Each step becomes explicit\ , reviewable\, and repeatable.In this talk\, I’ll show how to apply spec -driven development and explain my intuition for this approach. We’ll wa lk through an example: documenting requirements\, generating a plan\, crea ting tasks\, and guiding the AI through execution one step at a time. Alon g the way\, you’ll see techniques for controlling workflow\, reviewing c hanges\, and avoiding “black box” code generation.If you’ve tried co ding with AI tools but found them chaotic\, this session will give you a f ramework to make them reliable partners.\nSpeakers: Anton Arhipov\nTrack: Mind the Geek URL:https://vdt26.voxxeddays.ch/talk/spec-driven-development-with-ai-agents -from-high-level-requirements-to-working-software/ LOCATION:Room B3\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Mind the Geek END:VEVENT BEGIN:VEVENT UID:cfp-1151-8673@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T121000Z DTEND:20260206T125500Z SUMMARY:Write Once\, Accelerate Everywhere: GPU-Ready Java with TornadoVM DESCRIPTION:In the AI era\, accessing GPUs from Java is essential - but it still remains a challenge.

In this talk\, I will share a real-world e xample where simplifying redundant business rules\, identified by a busine ss analyst\, led to cleaner\, more maintainable code. We will dive into ho w collaboration between developers\, business analysts\, product managers\ , and other stakeholders can shape code quality from the ground up.By unde rstanding how business logic\, requirements\, and communication impact the codebase\, teams can avoid unnecessary complexity and create software tha t is simpler to maintain and scale.

But performances have frequently been sacrificed in the process. Applications may be slowed down by needless re- renders and a lack of control over state changes. These difficulties have paved the way towards the most recent changes in the Angular world.The lat est versions of Angular are addressing these issues with the signals and t he new control flow syntax. Signals offer a lightweight solution to contro l state and reactivity\, guaranteeing that updates only take place when re quired. In addition\, the new control flows provide less template logic\, more fine-grained lazy loading\, and enhanced efficiency. Those changes ar e steadily creating a path toward a zoneless future.This talk will showcas e this Angular renaissance and how it addresses real-world problems throug h live demos.

That is not sci ence fiction anymore. Large Language Models (LLMs) are reshaping how we wr ite software\, aiding developers and even non-developers alike in crafting code with unprecedented ease.But there is a catch. These models are fluen t in the world'\;s most popular programming languages\, like Python or Java\, and struggle when they face the dialects of industry: the in-house programming languages companies build for their own unique problems. LLMs often have little to no training knowledge of these languages\, which make s it difficult for them to assist in these specialized domains. For this r eason\, in-house programming languages are perceived as exotic by LLMs.In this talk\, I will share my experience in teaching new and exotic programm ing languages to LLMs. I will show the challenges we faced during the proc ess and how current techniques like retrieval-augmented generation\, few-s hot learning\, and fine-tuning open-weight models performed in this contex t.

These patterns demo nstrate the coordination and integration of multiple AI services to build sophisticated Agentic AI systems capable of handling intricate tasks.These Agentic Systems architectures can be grouped in 2 main categories: workfl ows\, where LLMs and tools are orchestrated through predefined code paths\ , and autonomous agents\, where LLMs dynamically direct their own processe s and tool usage\, maintaining control over how they execute tasks.The goa l of this talk is to give a theoretical overview of Agentic AI in general and these patterns in particular.

But what if that story was wrong?In this talk\, we’ll exp lore what happens when these two worlds actually fall in love. Drawing fro m real-world work inside the Quarkus\, Vert.x\, Netty\, and HotSpot teams\ , we’ll see how a custom Loom scheduler built on top of Netty brings tog ether the performance of event-driven I/O and the simplicity of virtual-th read-friendly blocking APIs.This isn’t a theoretical “what if”: it ’s a data-driven exploration born from experiments and collaborations be tween IBM\, Oracle Labs\, Oracle and Apple engineering teams. You’ll see how this approach reshapes how we think about async\, concurrency\, and s cheduling — and why some of the long-held assumptions about “reactive vs blocking” simply don’t hold up when measured scientifically.Along t he way\, we’ll dissect:How the Loom scheduler and virtual threads work u nder the hood.What happens when you run them over a Netty corePerformance implications and trade-offs measured empirically.State of art of similar p atterns from other languages (c++\, go\, ...)Why developers should challen ge inherited dogmas and base design choices on data\, not folkloreThis tal k is a technical love story\, but also a call to reason: Measure\, Don’t Guess. Because sometimes\, the forbidden relationships are the ones that can move the platform forward.\nSpeakers: Francesco Nigro\nTrack: Java URL:https://vdt26.voxxeddays.ch/talk/reactive-loom-a-forbidden-love-story/ LOCATION:Room C\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Java END:VEVENT BEGIN:VEVENT UID:cfp-1151-9101@cfp.dev DTSTAMP:20261004T231723Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20260206T160000Z DTEND:20260206T163000Z SUMMARY:Behavioral Software Engineering DESCRIPTION:According to the traditional economic theory\, markets are full y efficient and humans operate in them in a rational way. In the late 70s Daniel Kahneman and Amos Tversky started disproving this efficient markets hypothesis\, contrasting the consistently logical Homo Economicus (Econ) they depicted\, with the more realistic Human who takes decisions based on his questionable points of view. Doing so they gave birth to the study of the psychological factors involved in the making of these decisions\, cal led Behavioral Economics.The same flawed reasoning also impacts other fiel ds like software engineering: we cannot behave as cold Econ when spending or investing our money\, or as rational Engeen when coding. We are humans and this inevitably influences our choices.The anchoring effect and the av ailability bias affect how we benchmark and evaluate the performances of o ur programs. The pro-innovation and bandwagon biases drive our technical d ecisions\, making us to blindly follow hypes and gurus. The not-invented-h ere syndrome pushes us to create homemade tools instead of using de-facto standards. The framing effect makes us solving the same problem in differe nt ways\, depending on how it is presented.During this talk we will go thr ough these and other heuristics and shortcuts used by our brain\, as found by behavioral economists in almost 50 years of research\, and examine the m in the context of software engineering\, discussing their consequences o n the quality of our work.\nSpeakers: Mario Fusco\nTrack: People & Culture URL:https://vdt26.voxxeddays.ch/talk/behavioral-software-engineering/ LOCATION:Room A\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:People & Culture END:VEVENT END:VCALENDAR
