Gabriele Brambilla - Enhancing User Engagement Through Personalized Recommendation at Dow Jones Speaker Gabriele Brambilla Abstract Dow Jones has developed a content recommendation system leveraging Natural Language Processing (NLP) to understand the subtle connections between the vast array of articles it publishes (e.g. from the Wall Street Journal) and the diverse interests of its user base. This presentation will delve into the specific NLP methodologies employed to achieve this nuanced understanding. We will explore the models used to extract semantic meaning from textual content, enabling the system to go beyond simple keyword matching and identify conceptually related articles. Furthermore, the presentation will address a common challenge in recommendation systems: the tendency towards homogeneity and a lack of novel suggestions. We will detail our approach to mitigate this issue by strategically combining data-driven techniques with informed editorial oversight. This balanced strategy ensures that while user preferences are accurately reflected, it also introduces users to a broader spectrum of relevant and potentially surprising content, fostering discovery and exploration. Finally, we will provide a comprehensive overview of the lean and efficient data pipeline we have built to support these advanced recommendation techniques. This will include a discussion of the various data sources that are collected, processed, and integrated into the system. The presentation will conclude with evidence of the system's effectiveness, demonstrating the significant positive impact on user engagement metrics resulting from this enhanced semantic understanding and more diverse recommendation strategy.

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

Barbara Teruggi - A door with no locks? Let’s talk about threat modeling Speaker Barbara Teruggi Abstract Threat modeling isn’t exactly a new concept, but it has recently become a must-have in product design. With cybersecurity threats on the rise and the pressure to deliver faster, security often ends up on the back burner—usually discovered during QA or, worse, after the code is already out the door. At that point, it’s either a headless-chicken chase to fix things or a recipe for disaster. Developers are the ones who really know how applications are supposed to work, so security needs to be part of the conversation from the start. Yet, for some reason, threat modeling is still seen as a "cybersecurity expert-only" club. In this talk, I’ll walk through the threat modeling process, highlight key risk concepts, and show how we can all work together to avoid those "oops" moments. Because, honestly, building secure applications is way more fun when we’re all in it together! https://www.devbcn.com

Threat modeling is a must-have skill for any security-conscious developer. In her insightful Barbara Teruggi session at #devbcn25, she explores the concept of a 'door with no locks' and how to build secure systems from the ground up. Watch the full session here: buff.ly/mm3VcCM #devbcn25

Alvaro Sanchez M - Revealing the magic behind Java annotations Speaker Alvaro Sanchez Abstract Annotations, introduced in Java 5 two decades ago, have revolutionised how we develop Java applications. Traditional frameworks like Spring and Hibernate rely on runtime annotation processing using reflection to perform tasks such as dependency injection or implement persistence operations. Alternatively, the Java Annotation Processing API, introduced in Java 6 in 2006, allows developers to hook into the compilation phase to process sources and react to annotations present on them. This was leveraged by libraries like Lombok and Dagger, and frameworks such as Micronaut, although their way of processing annotations varies. Other frameworks like Quarkus perform the annotation processing during build time, instead of the compilation time. In this session, Micronaut Framework committer Álvaro Sánchez-Mariscal will explain with examples the different techniques that can be used for both runtime and compile-time processing of annotations, revealing the magic behind popular open-source projects. https://www.devbcn.com

Mario Macias - From PIDs to Pods: our journey to connect eBPF and Kubernetes Speaker Mario Macias Abstract eBPF allows to safely attach small programs in the Linux Kernel and inspect the runtime memory of the Kernel and userspace programs at runtime. This opens a wide range of possibilities for observability applications. However, the low-level approach of eBPF often difficults matching the inspected data with high-level concepts, such as the entities in your Kubernetes cluster. This talk describes our journey to make Kubernetes a first-class citizen in Grafana Beyla, an eBPF-based instrumentation tool that can run as a simple operating-system process but lets its users to keep talking about Pods, Deployments and Services.

Anshika Koul - Kotlin Multiplatform's Cross-Platform Brilliance at Norway's National Postal Service Speaker Anshika Koul Abstract Do you have a complex business rule-set problem? You know the kind where you have business rules (logic) spread across multiple platforms, systems and applications? Some of them might even be alter egos of the same rule hiding in different apps. You never know which one might turn up where, there is no single source of truth, solving errors takes hours of debugging, and making changes requires (oftentimes) painful coordination across teams and applications (ugh). We faced this exact challenge at Posten Bring As - Norwegian National Postal Service founded way back in 1647 - a 378-year-old institution with software spanning more generations than most families! Our business logic was scattered across multiple platforms, some almost as old as the company itself (well, not quite, but it sure felt like it). In my session I’m spilling the tea. We discover how the team at century-old Norwegian postal services giant tackled modern challenges with cutting-edge technology. We’ll look through real-world use cases at Posten Bring. We’ll reflect on what we did - key learnings, what went well & most importantly - what didn’t quite go as planned. We'll learn how KMP provides a unified framework for code sharing and execution across various platforms to solve the challenge of different codebases targeting different runtimes.
