#DevBcn #Java #Developers

It was so nice to present as speaker at #DevBcn, but also to join other talks and talk with old friends.

If you have the chance, I recommend you to attend DevBcn!

Isra Chahrazed -The Leaking Bucket: Women in Tech Speaker Isra Chahrazed Abstract Why do we see fewer women in tech, and how can we change this? This talk explores the journey of women in STEM, from young girls fascinated by science and technology to building successful IT careers. We will discuss the barriers women face, such as cultural stereotypes and lack of support, that cause the "leaking bucket" effect where women leave the tech pipeline at various stages. Through real-life stories and data, we'll highlight the unique contributions women bring to the tech industry and the importance of their presence. Most importantly, we’ll explore actionable strategies to support and retain women in tech, including mentorship programs, inclusive workplace policies, and community initiatives. Understand the what, why, and how of empowering women in tech and learn how we can all play a part in fixing the leaks in the bucket, ensuring more women not only enter but thrive in the world of IT. https://www.devbcn.com

Insightful session by Isra Chahrazed on the 'Leaking Bucket: Women in Tech' at #devbcn25! She shared powerful perspectives on the challenges women face in the tech industry and ways to close the gender gap. Watch the full session here: buff.ly/WgEORjW #DevBcn

Milen Dyankov - AI for Java Developers - From Buzzword to Code Speaker Milen Dyankov Abstract AI is undeniably a buzzword, but it is here to stay. What does this mean for Java developers? Can we design and build applications that harness the power of AI? Most importantly, where do we start? This session focuses on inference—using pre-trained models directly from your code. Instead of relying on proprietary APIs, it'll demystify the "magic" by breaking the AI buzzword down into familiar concepts and components. This will enable you to use AI models as naturally as you would work with databases or workflows. Through live demos, you'll learn to leverage basic embedding models, explore vector databases, and use tools like LangChain4J. By the end, you'll have a practical roadmap to kickstart your journey into Java-powered AI. https://www.devbcn.com

Catch Milen Dyankov's insightful session "AI for Java Developers - From Buzzword to Code" at #devbcn25! He'll dive deep into practical AI applications in Java - don't miss this chance to level up your skills. Check out the session recording: buff.ly/dNQRU2B #DevBcn

Richard Brough - Aligning DeepSeek R1 Speaker Richard Brough Abstract At Blue Beck, we were the first to publish re-aligned versions of DeepSeek’s R1 on Hugging Face, aligning the R1-Distil models with Meta’s Llama 3.x. Since then Perplexity AI have courted controversy upon the release of their R1-1776 model with statements about censorship in the original DeepSeek R1. This talk will focus on what it takes to re-align a language model to have a different bias to the original, without losing its capabilities, which is highly relevant in the polarised political environment while rapid advances in language models are occurring. There is a commonly held belief that whoever controls the models also controls the political bias of the output, and while that may hold true for proprietary APIs such as GPT4o & Claude, the emergence of powerful open source models that can be have their bias shifted with a relatively modest amount of compute upends that somewhat. The talk will look at some of the variants of open source models that have appeared, from the academic experiments with RightWingGPT and LeftWingGPT to some of the more disturbing examples that really highlight the risks. https://www.devbcn.com

Philip Miglinci - Mastering Modern Software Distribution: On-Prem, Air-Gapped, and BYOC Challenges Speaker Philip Miglinci Abstract Distributing software across on-premises, air-gapped systems, and bring-your-own-cloud (BYOC) setups presents unique challenges. During this talk Philip will share his experiences and learnings from helping companies distribute their software from binaries to Helm charts. For each of the following chapters we will dive into live examples showcasing common errors and proposing fixes that we will be immediately applied and tested. - Packaging Strategies: Semantic versioning, build automation, and dependency management. - Secure Artifact Distribution: Using OCI registries to restrict image tag access, attach SBOMs and regularly scan for CVEs. - Pre-Flight and Target Assessments: Preparing for complex environments with configuration validation and air-gapped packaging. - Deployment Methods: Comparing binaries, Docker images, Helm charts, and BYOC models. - Security and Application Boundaries: Securing Kubernetes deployments with namespaced vs. cluster-scoped installations. - Lifecycle Management: Updating installations, managing licenses, and communicating with teams. We also plan to have enough time for Q&A so we can address real-world deployment challenges from the audience live on stage. https://www.devbcn.com

Iveri Prangishvili & Jose Correa—Scaling Kubernetes Deployments Across +15'000 Namespaces Speaker Iveri Prangishvili&Jose Correa Abstract Ever wondered how Adobe handles daily infrastructure code deployments across more than 15,000 Kubernetes namespaces that power Adobe Experience Manager? In this session, we'll share how we increased deployment frequency, improved our DORA metrics, cut down engineers' waiting times, and sped up service recovery when things go wrong. We'll walk you through the strategies that helped us streamline deployments and enable fast, reliable code delivery at scale. By combining SlackOps with GitOps, we significantly boosted efficiency. Join us as we dive into CNCF-hosted tools like Prometheus and FluxCD, which we use to monitor and manage rollouts in real time, giving us insights into deployment health and performance. Finally, we’ll explore how we measure and improve key software delivery metrics, showing how these improvements enhance team efficiency and the overall developer experience. https://www.devbcn.com

Cedric Clyburn - Going from containers, to pods, to Kubernetes – help for developer environments! Speaker Cedric Clyburn Abstract Today, Kubernetes is the undisputed go-to platform for scaling containers. But for developers, Kubernetes can be daunting, particularly when working with the discrepancies between local and production environments. Podman and Podman Desktop bridges this gap. In this talk, you’ll be introduced to Podman and witness the unveiling of Podman Desktop, an open-source GUI tool that streamlines container workflows and is compatible with Podman, Lima, Docker, and more. Podman Desktop serves as a beginner-friendly launch pad to Kubernetes, enabling developers to spin up local clusters (with Kind and Minikube) or work with remote environments. A demo will be given that helps you navigate the paths necessary to transition from app to containers, to pods, and ultimately to Kubernetes, highlighting how it reduces discrepancies and enables predictability in your deployments by leveraging Podman and Podman Desktop's perks and security advantages. You'll also learn how you can benefit from Podman Desktop to streamline your container development processes! https://www.devbcn.com

Alina Yurenko - From CLIs to LLMs: 5 cool applications to build with GraalVM Speaker Alina Yurenko Abstract Many people know GraalVM for its performance and resource efficiency. One of the questions that often remains is what applications one can build with it in practice. While serverless and microservices applications are an obvious first choice, there’s so much more. You can build quick and compact CLI applications, that are also very fast to respond. You can build an entire full-stack application, with the backend combining the power of the Java and platform and performance of GraalVM. You can even build an LLM inference engine in pure Java and make it very fast with GraalVM’s ahead-of-time optimizations. In this hands-on session we’ll go through all of those categories of apps and more, as well as tips, recommended practices, and gotchas. https://www.devbcn.com
