Large Language Models (LLMs) are often experienced as black boxes through chat interfaces or APIs. Running a local LLM enables direct inspection of its architecture, weights, and output logits. This provides insight into how the model operates internally.

After a brief introduction to the core ideas behind LLMs, I will demonstrate how to load a small pretrained model, run it locally, inspect...

Open source relies heavily on engineering-driven process; fast feedback loops, terminal tools, and Git workflows. But in order for open source to thrive, we need to include open design. To truly succeed and scale, we must build experiences that are as empowering to use as they are to code.

In this talk, we will explore how to dismantle the ‘us vs them’ mentality between engineers and designe...

In a large organization, developers shouldn’t need to manage infrastructure complexity. Most configurations are predefined through standardized templates, keeping teams focused on code and business logic rather than cluster tuning. Our challenge was that Kubernetes nodes appeared fully allocated while much of their capacity remained unused due to oversized resource requests. By introducing dyna...

Desde laboratorios personales hasta entornos de producción, los contenedores están dominando la forma en la que empaquetamos y desplegamos software. Sin embargo, están muy lejos de ser esas robustas cajas de metal herméticas que su nombre nos sugiere.

El aislamiento por defecto que nos proporcionan los namespaces y cgroups presenta limitaciones arquitectónicas claras al compartir el kern...

Abstract

Docs-as-code isn't new. We'll dip into its evolution, moving from the foundations of UNIX towards an AI-assisted present and future.

With live demonstrations, we’ll look at docs-as-code using UNIX V7 on a PDP-11/70 (PiDP11/70) from 1978 and compare with a modern, open-source localized documentation environment at SUSE. Conceptually, not as different as you would initially th...

Open source needs contributors, but traditional onboarding is broken. Finding a project, understanding the codebase, and making a first pull request is intimidating. Meanwhile, maintainers desperately want help but lack the bandwidth to guide newcomers. We need a paradigm shift: moving from contributors working across isolated repositories to tasks finding them in a centralized, supported env...

¿Qué tienen en común todos los cuentos populares? Caperucita, los tres cerditos, hansel y gretel... Todos ellos son fábulas, que enseñan una lección útil para la vida: no reveles información privada a un extraño, no te fies de la infraestructura, hay gente que quiere engañarte, etc.

En los tiempos que corren, nuestras vidas estan ligadas a activos digitales como nuestros datos personales, nu...

Router Freedom is a cornerstone of digital self-determination: users should be free to choose and use their own router or modem instead of being forced to rely on provider-supplied equipment. In Europe, this right has been recognized for years, but implementation has been uneven, with national exceptions and regulatory fragmentation weakeni...

AI has found its killer app: the coding agent. Ever since Claude Code redefined the programming practice with its meteoric growth, all tech teams are adopting coding agents en masse. Claude Code, Cursor, Codex, Copilot... the list is staggering and a question looms large: can open source compete in the global coding arena?

In this talk, we will present a full open source stack that provides ...

Construir sistemas de IA multi-agente hoy en día es como la Torre de Babel en su peor momento: LangChain, CrewAI, frameworks propietarios y protocolos incompatibles, cada uno hablando su propio idioma sin entenderse. El resultado es predecible: se invierte más tiempo en integración que en resolver el problema de negocio, y la torre nunca termina de construirse.

odern applications are glued together to work as a single unit where end-users access the Frontend to interact with the Application. But behind the curtains (i.e. Backend), there are multiple microservices working together to provide this experience. These services typically consist of core application layers (Python, Go, etc.), databases, A...
