Title: Syncing your Database To OpenSearch In Real-Time
Description: You've been tasked with implementing a data streaming pipeline for propagating data changes from your operational Postgres database to a search index in OpenSearch. Data views in OpenSearch should be denormalized for fast querying, and of course there should be no noticeable impact on the production database.
In this session we'll discuss how to build this data pipeline using two popular open-source projects: Debezium for log-based change data capture (CDC) and Apache Flink for stream processing. Join us for this talk and learn about
* Setting up change data streams with Debezium
* Efficiently building nested data structures from 1:n joins
* Deployment options: Kafka Connect vs. Flink CDC
We'll also touch on some advanced aspects like observability and consistency checks for your realtime data pipeline.
Bio: Gunnar Morling is a software engineer and open-source enthusiast by heart, currently working at Decodable on stream processing based on Apache Flink.

Kevin Wittek
Senior Engineering Manager @Docker
Title: Curse of the Pharaohs: Rethinking the Testing Pyramid with Testcontainers
Description: For many years, we have taken the monuments built by the ancients for granted: The classical testing pyramids! And while they are an essential part of the cultural heritage of the IT realm, different tribes differ in their definition and composition. And what if we would listen to the voices of the cultists and heretics, that seduce us to break with the ways of old and start our exodus to explore a universe of new forms and shapes? Will those bring us closer to our Xanadu, where milk and honeydew flow with each continuous deployment, or will we get lost in the eldritch tar pits, just as so many primeval beasts before us?
In this talk, we want to embark on an archaeological journey into the history of the testing pyramid: Who envisioned it first and in which context? By which technical constraints was it shaped and is it possible, that just as the Egyptian and the Mesoamerican pyramids developed independently from each other at different times, on two different continents, the testing pyramid also has multiple origin stories? And what might the future hold? Do new developments in hardware, software and architectural patterns alike allow us to rethink the traditional pyramid?
And to bring us finally back to the future, we will look at how Testcontainers – a popular JVM testing library that harnesses Docker to easily, reliably, spin up test dependencies – can support us in assembling the test suite structure, that best suits the needs of our applications and our developers.
Bio: Testcontainers maintainer, passionate about FLOSS, containers and Java. Oracle ACE Pro. Likes to write Python programs to support his wife in performing behavioral science experiments with pigeons. Plays the electric guitar and is a musician in his second life.
After many years working in the industry as a software engineer and a short detour into the world of academic blockchain research, Kevin now found a new home at Docker as an Engineering Manager, together with his beloved Testcontainers project.

Founder @TangoWellnessClub
Title: Uyumsuzluktan Gelen Bir Uyum: İlişkide İletişimde Tango
Description: Bugün, bir dansın sadece adı değil, aynı zamanda bir yaşam tarzı ve kültürel bir ifade biçimi haline geldiği bir dünyada toplanıyoruz. Tango, derin duyguların, tutkunun ve uyumsuzluğun dansı olarak bilinir. Ancak paradoksal bir şekilde, bu uyumsuzluk, bir uyumun doğmasına neden olur.
Bu sunumda, tango dansının sadece bir dans olmanın ötesindeki anlamını keşfedeceğiz. Tango, insan duygularının karmaşıklığını ifade etmek için bir araç olarak nasıl kullanılır? Tango'nun kültürel ve tarihi önemi nedir ve günümüzde nasıl yaşatılıyor? Bu soruların cevaplarını ararken, tango'nun insanları nasıl bir araya getirdiğini ve uyumsuzluktan nasıl bir uyum doğduğunu göreceğiz.
İçimizdeki duyguları, tutkuları ve hatta kırılganlıkları ifade etmek için tango'nun nasıl bir platform sağladığını inceleyeceğiz. Tango, bedenimizin ve ruhumuzun birbirine uyum sağlaması için bir alan sunar, ancak bu uyum bazen beklenmedik bir şekilde, uyumsuzluktan doğar.
Bu sunumda, tango'nun ritmiyle, melodisiyle ve duygularıyla bizi nasıl etkilediğini keşfedeceğiz. Aynı zamanda, tango'nun insan ilişkilerinde nasıl bir metafor olduğunu ve uyumun bazen uyumsuzluktan geldiği gerçeğini göreceğiz.
Bio: Elif Ünlüataer, Uludağ Üniversitesi İşletme Fakültesi'nden mezun olmuştur. On bir yıllık kapsamlı kurumsal deneyimin ardından, tutkusunu mesleğe dönüştürmüş ve kariyerini tango üzerine inşa etmeye karar vermiştir. Elif, 2009 yılında partneriyle birlikte Türkiye Dans Federasyonu tarafından düzenlenen Kulüpler Arası Arjantin Tango Yarışması’nda kategorisinde birincilik ödülüne layık görülmüştür. Tango eğitimi ve kültürünün derinliklerine dalmak için bir süre Arjantin'in Buenos Aires şehrinde yaşamıştır. Orada, tangonun sadece bir dans formu olmadığını, aynı zamanda günlük yaşama, iletişime ve liderlik becerilerine olumlu katkılar sağlayabilecek değerler barındırdığını keşfetmiştir.
Bu anlayışla yola çıkarak TangoWellness'ı kurmuş ve burada tangoyu, sıradan bir dans kursunun ötesinde, bir yaşam biçimi olarak sunmaktadır. "İlişkide İletişimde Tango" ve "Tangoyla Liderlik" gibi başlıklar altında, tangonun yaşamın her alanında uygulanabilir değerlerini, bireylere ve kurumlara aktarmaktadır. Elif Ünlüataer, tangoyu hem bir sanat formu hem de kişisel gelişim aracı olarak benimsemiş ve bu vizyonuyla birçok kişiye ilham kaynağı olmuştur.

Software Quality Expert @Alliander
Title: Bootiful Kubernetes Operators
Description: You know what's fun? Automating the ever livin' heck out of infrastructure! Slaying that YAML! Nobody wants to painstakingly build something and then spend weeks trying to write the YAML to describe it to the infrastructure. Thankfully, Kubernetes provides composability through abstractions like operators, controllers, and custom resource definitions.
These days, it's trivial to extend Kubernetes with a Spring Boot application, turn it into a GraalVM native image that runs in a Docker container, and then deploy that. Join and we'll learn how to extend and automate Kubernetes with Spring Boot and Spring Native-powered custom operators and eliminate that ever-so-pesky YAML.
Bio: Ties is a software engineer with passion for concepts, sofware engineering fundamentals and helping others. He combines these passions by doing public speaking,
volenteer work for organisations like Devoxx4kids and codingcoach and working as a Software Quality Expert at Alliander.

Title: Functional Programming In Java 22 - Understanding the Building Blocks of FP
Description: Functional programming promises huge advantages, but it still remains a mystery to many. In this talk, I'll focus on explaining key concepts such as lazy, immutability, currying, composition, and also explain topics such as ADTs, morphisms, lambda calculus and advanced pattern matching in Java 22.
This talk is about the practical use of functional programming in an object-oriented language like Java. We know that it's very difficult to write pure code in a functional style in Java because the language lacks important elements such as immutability, laziness, higher order types, stronger type inference, better function composition and currying, tail-call optimization, and stronger pattern matching. These deficiencies lead to a lower degree of abstraction, poorer decomposition, and we cannot express ourselves as elegantly as we would like. So why should we care about functional programming in Java?
The answer lies in the fact that by learning techniques from other languages, you also become a better developer in the language you normally use. Java 21 now supports "Unnamed Patterns and Variables", and with the existing support for Sealed Interfaces and Record Patterns, some Java code can now be written much simpler and more expressively.
This is an informal look at functional programming, the aging java.util.function library, and the latest additions in JDK22 that bring Java closer to other JVM languages such as Kotlin. The talk is well suited for those who have not engaged much in functional programming, but who wish to get a bit of inspiration.
Bio: Dervis is an experienced Java-developer and principal officer, currently working for the Norwegian Labour and Welfare Administration. He is passionate about programming languages, functional programming and algorithms. Dervis is a Java Champion and the leader of the Norwegian JUG JavaBin (Dukes Choice Award winner in 2019). Dervis has spoken at several international conferences as well as being a regular speaker at local meetups in Norway.
