At the Yay-Yay Conf, we offer two types of workshops: Canela and Crema workshops.
Crema workshops are paid workshops for ticket holders as well as for the general public. You can check the fee for each workshop below.
Canela workshops are free for Early Camarón and Bokeron ticket holders. For Standard Tuna tickets are available with a 50% discount. For Last Callamar tickets are available with a 30% discount. In all cases previous registration is MANDATORY. Conference ticket holders can register on our webpage with a special promo code, which is sent together with the ticket order confirmation. Check out the following video tutorial. For those who are not conference ticket holders, admission is at a fee of €50.
Go from an empty project to a working GraphQL API an AI agent can use. Build it with SpringGraphQL, expose it through MCP, and watch an LLM discover and query it live. No GraphQL or MCP experience needed.
Virtual threads and structued concurrency unlock a new concurrency programming paradigm in Java. We will explore these and learn how to structure concurrent code, process and propagate errors and cancellation, and observe thread relationships.
Building AI agents? Not every step needs a giant model. It's about right-sizing: run an agent's frequent, narrow decisions (routing, tool use, self-correction) on Small Language Models on CPUs, and reach for larger models where the task genuinely calls for them. On Kubernetes, with llama.cpp, KEDA, and Karpenter.
Build safer coding agents by containing them instead of relying on approval prompts. Understand real attack paths, create a cross-platform sandbox from scratch, and verify that your protections actually work before trusting agents with sensitive access.
Go hands-on with DuckDB — the embedded analytical database that runs everywhere. Build browser-based dashboards, serverless pipelines, and lean analytics apps while learning how embedded OLAP reshapes modern data architectures.
