As generative AI moves into production, developers face unprecedented security challenges beyond traditional approaches. This session examines how groups like OpenSSF and OPEA are developing frameworks and best practices for GenAI security. Learn about emerging threat taxonomies, practical security patterns, and community-driven initiatives addressing concerns from prompt injection to model supply chain security. Gain insights into work-in-progress standards being shaped by open source collaboration, and discover how to apply these evolving best practices to secure your GenAI applications.
As AI applications grow in complexity, traditional prompt engineering methods fall short, creating fragile and costly systems. This talk introduces next-generation prompt engineering, offering adaptable, cost-optimized techniques for stable performance across diverse, including open-source, environments. Topics include multi-model consistency, model adaptability, synthetic data for robust testing, and cost optimization through structured prompting. Attendees will gain actionable insights to build scalable, reliable AI applications that thrive in a multi-model, open-source landscape.
Nix in the Wild is a series where we interview users of Nix and ask them about their journey. We want to know about the good moments and the bad, and we want to tell it like it is.
What makes users choose Nix? How long does it take for them to get their colleagues onboard? What do they learn along the way?
In this quick talk, Ross from Flox will go over a few of the most amazing stories from Nix in the Wild (rawr!)...and let you know how we can help you tell yours.
Evaluating packages with big dependency trees with nix is time consuming. Currently, while there is a local eval cache, evaluation costs are sum up locally but also globally as eval caches are generally not shared across machine or user boundaries. In other places such as searching packages, evaluation is impossible, prohibitively expensive, or just annoying. In this talk I want to introduce different approaches to avoid evaluations, how they are motivated and what their limits are.
OpenStack resolves many challenges even in container era and RAN. Tacker is contributing telecom usecase to O-RAN SC which is a collaboration between the O-RAN ALLIANCE and Linux Foundation aiming to achieve a solution to unify and accelerate the evolution in the RAN. Tacker is designed for managing lifecycle of RAN components and enables user to deploy network functions on OpenStack or Kubernetes for scalability and availability. In O-RAN SC model, Tacker manages network functions with StarlingX for autonomous deployment.
Tigris is a globally distributed S3 compatible object storage, where buckets are no longer tied to a region. In this talk, we share our journey about how we use metrics, traces and logs.
Uncover the risks of online payment processing and how to safeguard against them. Understand what motivates cyber criminals across three major attack types and learn effective strategies for detection and mitigation.
Join us for a hands-on "Open Source for Good" workshop where participants of all skill levels will contribute to real-world social impact projects. Working alongside nonprofit leaders, you'll learn contribution workflows while making meaningful improvements to vetted projects. From beginner-friendly documentation updates to advanced feature implementation, you'll gain practical experience with GitHub tooling and collaborative development practices.
This talk presents the architecture and implementation of a real-time voice understanding system for retail environments, powered by open source AI technologies and deployed on NVIDIA Jetson devices. The system integrates automatic speech recognition (ASR) and large language models (LLMs) to process customer interactions in real-time, enabling conversation understanding, summarization, and sentiment analysis. We will explore system architecture design, selection and evaluation of ASR and LLM models, design trade-offs between latency and accuracy, and share performance test results.
Infrastructure lays the foundation for every daily function and open source drives innovation, cost savings, and adaptability. Together, open infrastructure has adapted to global and regional trends to disrupt proprietary market holds and drive human progress. In the face of recent trends, like licensing changes and redefining infrastructure for AI, open source communities are continuing to collaborate to evolve the projects behind an $8.8 trillion USD market.
