Digitale Woche Dortmund 2026
Digitale Woche Dortmund brings together companies, experts and anyone interested in digitalisation and technology to share knowledge and experiences. In 2026, Karakun once again actively contributed to the event with several talks and the Hackergarten Dortmund.
Recordings of our talks are now available online. Here you can find the videos and presentation slides covering the EU AI Act, the Cyber Resilience Act (CRA), Software Bills of Materials (SBOM), modern OCR, antifragile software and browser security.
Cyber Resilience Act: What Developers Need to Know
The Cyber Resilience Act (CRA) introduces new requirements for digital products placed on the EU market with direct implications for software development. But what does the regulation mean for developers in practice?
Ixchel Ruiz and Markus Schlichting explain what the CRA requires from software teams and what this means for software development and dependency management. Software Bills of Materials (SBOM) and the software supply chain play an important role. Using practical examples, they cover challenges such as transitive dependencies and shaded JARs as well as tools including CycloneDX and Dependency-Track.
EU AI Act: Compliance Without Metrics – How Does That Work?
The EU AI Act requires certain AI systems to demonstrate compliance with regulatory requirements. But how can compliance be assessed when the quality of a non-deterministic system cannot be captured by a single metric?
Mike Mannion shows how statistical methods and probabilistic testing can be used to systematically evaluate the performance of non-deterministic AI systems. The talk explores predefined criteria, robust baselines and well-founded decision rules – and how they can provide traceable evidence of an AI system’s quality.
Modern OCR in Resource-Constrained Environments
Optical Character Recognition (OCR) is an important building block for automating the processing of scanned documents. But how can high recognition quality and robust results be achieved when computing power and other resources are limited?
Drawing on real-world applications, Olmo Barberis shows how OCR solutions have evolved from traditional approaches using dictionaries and rule-based post-processing to modern pipelines based on open-source frameworks, vision models and LLMs. Using concrete examples, he compares different approaches and explores the engineering trade-offs between efficiency, reliability and maintainability.
Unbreakable by Design: The Secret Tech of Antifragile Software
Failures and disruptions cannot be completely avoided in complex software systems. Antifragile systems go a step beyond resilience: they use failures, variability and unexpected events to evolve and become more robust over time.
Iryna Dohndorf explores the technical principles behind antifragile software. The talk covers approaches including fault tolerance and fault handling, automated software repair, fault injection in production and Test-Driven Development (TDD) – and examines how antifragility can be incorporated into software development and architecture from the outset.
What Your Browser Reveals About You
Browsers reveal a surprising amount of information when we visit a website – often more than users realise. This can allow websites to recognise visitors even without a login. And some measures intended to protect privacy can inadvertently make identification even easier.
François Martin shows what information different browsers expose to websites and how these differences affect the ability to recognise individual users. He also explores what users can do to protect themselves – and where the limits of these measures lie.
