Doe s that mean we need to drop everything we’ve built and become data scien tists instead now? Fortunately\, we can infuse AI models built by actual A I experts into our applications in a fairly straightforward way\, thanks t o some new projects out there. We promise it’s not as complicated as you might think! Thanks to the ease of use and superb developer experience of Quarkus and the nice AI integration capabilities that the LangChain4j lib raries offer\, it becomes trivial to start working with AI and make your s takeholders happy :)In this session\, you’ll explore a variety of AI cap abilities. We’ll start from the Quarkus DevUI where you can try out AI m odels even before writing any code. Then we’ll get our hands dirty with some code and exploring LangChain4j features such as prompting\, chaining\ , and preserving state\; agents and function-calling\; enriching your AI m odel’s knowledge with your own documents using retrieval augmented gener ation (RAG)\; and discovering ways to run (and train) models locally using tools like Ollama and/or Podman AI Lab. In addition\, we’ll take a look at observability and fault tolerance of the AI integration and compile th e app to a native binary. Maybe we’ll even try some new features\, such as generating images or audio! Come to this session to learn how to build AI-infused applications in Java from the actual Quarkus experts and engine ers working on the Quarkus LangChain4j extensions. This is also an opportu nity to provide feedback to the maintainers of these projects and contribu te back to the community.\nSpeakers: Mario Fusco\, Kevin Dubois\nTrack: Da ta & AI URL:https://vdt25.voxxeddays.ch/talk/create-your-own-ai-infused-java-apps-w ith-langchain4j/ LOCATION:Workshop 3\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Data & AI END:VEVENT BEGIN:VEVENT UID:cfp-1151-7702@cfp.dev DTSTAMP:20260920T145820Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20250117T080000Z DTEND:20250117T081500Z SUMMARY:Welcome to the 10th edition DESCRIPTION:Welcome to the 10th edition of Voxxed Days Ticino.The Developer Community conference!10 years have passed since we started this journey.W e will shortly go through our story and dream about our future as a local community.\nSpeakers: Tiziano Leidi\, Federico Yankelevich\nTrack: Managem ent & Methodologies URL:https://vdt25.voxxeddays.ch/talk/welcome-to-the-10th-edition/ LOCATION:Room B1\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Management & Methodologies END:VEVENT BEGIN:VEVENT UID:cfp-1151-7703@cfp.dev DTSTAMP:20260920T145820Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20250117T082000Z DTEND:20250117T084000Z SUMMARY:Devoxx: A Journey Through the Past\, Present\, and Future DESCRIPTION:During this keynote\, we’ll have a quick look at the history\ , present\, and future of Devoxx and the transformative role of technology throughout its journey.We’ll explore how Devoxx started as a Java commu nity-driven initiative\, growing into a global community for developers to share\, learn\, and innovate.\nSpeakers: Stephan Janssen\nTrack: People & Culture URL:https://vdt25.voxxeddays.ch/talk/devoxx-a-journey-through-the-past-pres ent-and-future/ LOCATION:Room B1\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:People & Culture END:VEVENT BEGIN:VEVENT UID:cfp-1151-8501@cfp.dev DTSTAMP:20260920T145820Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20250117T084000Z DTEND:20250117T090000Z SUMMARY:30 years of Java DESCRIPTION:30 years ago Java and the JVM appeared in the software developm ent landscape\, changing it forever by introducing concepts and features t hat we now give for granted but at time were an authentic revolution like: the removal of incidental complexities from previous languages like C++\, such such as pointers\, memory management\, and explicit handling of low- level operations\, the platform independence allowing to write and compile a program once and run it on any operating system or the native support f or multithreading and distributed computing.Even more surprisingly Java ke pt innovating\, release after release and year after year\, adding more an d more capabilities and characteristics like generics\, lambdas\, a module system\, pattern matching and virtual threads without even breaking backw ard compatibility. You can take a program written 30 years ago for Java 1. 0 and run it on the latest JVM and very likely it will still execute flawl essly and with the same outcome.In this talk we will shortly revise the hi story of Java\, from its origin to the current state and beyond\, with a q uick glimpse on what we could expect in the near future.\nSpeakers: Simone Bordet\nTrack: Backend Development URL:https://vdt25.voxxeddays.ch/talk/30-years-of-java/ LOCATION:Room B1\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Backend Development END:VEVENT BEGIN:VEVENT UID:cfp-1151-7705@cfp.dev DTSTAMP:20260920T145820Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20250117T092000Z DTEND:20250117T100500Z SUMMARY:How difficult can it be to write efficient code?

They have an endless flood of tasks and responsibilities on thei r shoulders\, whilst battling an ever-increasing sea of potential technolo gies and tools to use. Change is needed! So\, build a dam with us through platform engineering and IDPs.In this session\, we’ll explore the concep ts of platform engineering and Internal Developer Platforms (IDPs) and how they can help to relieve the cognitive load on developers\, help to stand ardize technologies and tools used throughout an organization\, streamline CI/CD pipelines and in essence enable greater developer productivity. We ’ll investigate how this can all be achieved in the cloud\, with example applications running in OpenShift\, with Red Hat Developer Hub as the bas is of our IDP.\nSpeakers: Grace Jansen\, Maarten Vandeperre\nTrack: Build & Deploy URL:https://vdt25.voxxeddays.ch/talk/platform-engineering-101-building-inte rnal-developer-platforms/ LOCATION:Room E\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Build & Deploy END:VEVENT BEGIN:VEVENT UID:cfp-1151-7708@cfp.dev DTSTAMP:20260920T145820Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20250117T101500Z DTEND:20250117T110000Z SUMMARY:Complementing LLM with agentic AI: a Quarkus story on Artificial In telligence DESCRIPTION:What AI can do nowadays is simply mind-blowing. I must admit th at I cannot stop being surprised and sometimes literally jumping from my s eat thinking: "\;I didn'\;t imagine that AI could ALSO do this!&quo t\;. What is a bit misleading here is that today what we tend to identify with Artificial Intelligence is actually the employment of Large Language Model which is only a subset of all AI technologies available: ML is a fra ction of the whole AI-story\, while agentic AI enables the implementation of more general use cases\, for instance also involving the usage of Symbo lic AI to encode the business logic of a specific domain through a set of human-readable and transparent rules.In fact there are many situations whe re being surprised is the last thing that you may want. You don'\;t wan t to jump from your seat when your bank refuses your mortgage without any human understandable reason\, but only because AI said no. And even the ba nk may want to grant their mortgages only to applicants who are considered viable under their strict and well-defined business rules. Given these pr emises\, it is interesting to mix different complementary technologies in order to overcome the limited auditability and the risk of hallucinations implicit in the usage of a Large Language Model alone. In this talk we wil l discuss\, with practical examples\, some of the multiple patterns emergi ng in this field like RAG\, external tools invocation and guardrails. We w ill also demonstrate why this could be a winning architectural choice in m any common situations and how Quarkus through its langchain4j and drools e xtensions makes the development of applications integrating those technolo gies straightforward.\nSpeakers: Mario Fusco\, Daniele Zonca\nTrack: Data & AI URL:https://vdt25.voxxeddays.ch/talk/complementing-llm-with-agentic-ai-a-qu arkus-story-on-artificial-intelligence/ LOCATION:Room B1\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Data & AI END:VEVENT BEGIN:VEVENT UID:cfp-1151-7710@cfp.dev DTSTAMP:20260920T145820Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20250117T101500Z DTEND:20250117T110000Z SUMMARY:Passkeys in practice: implementing passwordless apps DESCRIPTION:Passwords. They'\;re everywhere\, they get leaked... A secur ity nightmare! A work-around is to a delegate authentication to a third pa rty\, for example using OpenID Connect. But sometimes you can'\;t or do n'\;t want to do that - can you go password-less\, with user-friendly f lows?Passkeys\, and more specifically\, is a browser-based technology that allows you to log in using physical devices\, such as a Yubikey\, or MacO S'\;s TouchID or iOS'\; FaceID. It has been well-supported by browse rs for multiple years now. With this technology\, we can make our apps aut henticate users without a password.In this presentation\, we will discuss the basics of WebAuthN\, and use the brand new support for passkeys in Spr ing Boot 3.4 to integrate it in an existing application.\nSpeakers: Daniel Garnier-Moiroux\nTrack: Security URL:https://vdt25.voxxeddays.ch/talk/passkeys-in-practice-implementing-pass wordless-apps/ LOCATION:Room B3\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Security END:VEVENT BEGIN:VEVENT UID:cfp-1151-7709@cfp.dev DTSTAMP:20260920T145820Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20250117T101500Z DTEND:20250117T110000Z SUMMARY:Optimizing Resource Usage in Kubernetes DESCRIPTION:Moving to Kubernetes opens the door to a world of possibilities \, the amount of workloads that can be run and the flexibility it provides . However this comes at a cost on managing the resources used by many appl ications and teams. Java applications can be specially challenging when ru nning in containers.At Adobe Experience Manager we run our cloud service o n more than 50 clusters. We make extensive use of standard Kubernetes capa bilities to reduce resource usage and we have also built some solutions at several levels of the stack to improve it.From autoscaling to workload hi bernation\, from automated resource requests to Kubernetes Jobs\, we have experimented with and implemented several features that decrease our resou rce usage and lower the cost of running many Kubernetes clusters at scale. Both at workload resource level and also at achieving higher density clus ters that reduce the number of clusters we need and the operating costs.\n Speakers: Carlos Sanchez\nTrack: Build & Deploy URL:https://vdt25.voxxeddays.ch/talk/optimizing-resource-usage-in-kubernete s/ LOCATION:Room C\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Build & Deploy END:VEVENT BEGIN:VEVENT UID:cfp-1151-8252@cfp.dev DTSTAMP:20260920T145820Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20250117T101500Z DTEND:20250117T110000Z SUMMARY:Bulk data processing and PostgreSQL thingy DESCRIPTION:This talk dives into the real-world challenges of handling larg e-scale data processing in a banking environment\, with a focus on Postgre SQL\, Hibernate\, and data persistence best practices.

In this tal k we will shine lights on these two awesome features StructuredTaskScope a nd ScopedValue.To be able to get a deep understanding of how we can use th em to their full potential\, we will start with an empty Java application. In a live coding session\, we will iteratively update it together to a fu lly functioning\, concurrent web application by combining Virtual threads with StructuredTaskScope and ScopedValue.During the process we will see wh y we should use ScopedValues instead of ThreadLocals when possible and how to build our own StructuredTaskScopes tailored to our needs.The goal of t his talk is to provide to everyone who attends a deep understanding of how these new features work and how they can be used in a real life scenario. \nSpeakers: Christian Woerz\nTrack: Backend Development URL:https://vdt25.voxxeddays.ch/talk/structuredtaskscope-and-scopedvalue-ge t-the-most-out-of-virtual-threads/ LOCATION:Room B3\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Backend Development END:VEVENT BEGIN:VEVENT UID:cfp-1151-7718@cfp.dev DTSTAMP:20260920T145820Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20250117T121000Z DTEND:20250117T125500Z SUMMARY:Information Reliability Service - a novel approach to fraud detecti on DESCRIPTION:Over the past years\, criminal activities on the Swiss Post por tal have amounted to approximately 5 million Swiss Francs per year . Crimi nal organizations and their activities have become increasingly sophistica ted and organized over time\, with cybercrime remaining a significant conc ern for online retailers and services.In this presentation we address the challenges of fraud detection and imbalanced datasets\, outlining the proc edures implemented to manage data access at an enterprise level within Swi ss Post. We present a machine learning approach to detect potential fraudu lent addresses\, preventing the activation of an account when risk is iden tified. Our innovative strategy employs a contextual Multi-Armed Bandit (M AB) model\, trained on shipment data and expert fraud evidence\, to take a ctions that maximize rewards by minimizing potential fraud cases. This nov el approach\, leveraging artificial intelligence and modern reinforcement learning techniques\, is fully hosted on a cloud platform\, allowing for o n-demand scaling based on specific time requirements.We explore innovative machine learning approaches\, including MLOps and our contextual MAB-base d strategy\, discussing their implementation and benefits. The empirical r esults\, based on real-world data from Swiss Post logistic services\, demo nstrate that we can successfully identify a portion of the fraudulent addr esses with the ability to improve our algorithm over time through expert f eedback.

They serve as one of our last lines of defense against bugs and subpar code reaching production. Yet\, they often turn into annoying tasks riddled with frustration\, hostility\, unclear feedback and lack of standard practices. How can this crucial process be improved? Key topics i nclude:1. Creating review-friendly pull requests: Demonstrating how to pre pare a pull request2. Effective code reviews: Showcasing how to approach r eviews\, provide constructive feedback\, and enhance collaboration through positivity.3. Using automated tools for quality assurance: Demonstrating tools for code consistency and quality checks - eliminating needless discu ssions and focusing on core changes. This session will leave attendees wit h practical tactics for improving pull requests\, performing better code r eviews\, and a suite of tools to simplify the review process and boost cod e quality.\nSpeakers: Paco van Beckhoven\nTrack: Management & Methodologie s URL:https://vdt25.voxxeddays.ch/talk/cracking-the-code-review/ LOCATION:Room E\nPalazzo dei Congressi\nLugano\, Switzerland CATEGORIES:Management & Methodologies END:VEVENT BEGIN:VEVENT UID:cfp-1151-7721@cfp.dev DTSTAMP:20260920T145820Z SEQUENCE:0 STATUS:CONFIRMED DTSTART:20250117T130500Z DTEND:20250117T135000Z SUMMARY:DevOps for Java Developers (or maybe against them?!) DESCRIPTION:"\;DevOps"\; is the operations people’s crafty plan t o make Java developers do other people'\;s work\, but we are smart enou gh to see right through this naive rebranding trick!Baruch suggests you th ink about it: we\, the Java developers\, have written all the code.

We are!)\; so we are DONE.Now\, out of the blue\, a bunch of "\;th ought leaders"\; (all with an operations background\, mind you!) are t rying to tell us that we have to learn YAML\, Docker\, Kubernetes\, and Te rraform to deploy our software because suddenly it is our concern?!In this talk\, we'\;ll discuss why Java developers do or don’t need DevOps. We'\;ll consider arguments made by DevOps visionaries and see whether t hey hold water.
