Code the Continuum
30 June – 01 July 2026
A two-day hackathon hosted by the University of Cagliari and organised by CEI-Sphere, O-CEI and COP-PILOT.
Code the Continuum brings together students, developers, researchers, innovators, open-source communities, pilot teams and solution providers for two days of hands-on collaboration around the cloud-edge-IoT continuum.
The event creates a practical space for experimentation, co-creation and exchange, where participants will work on real challenges related to open technologies, interoperability and the reuse of assets across large-scale pilot environments.
What to expect
Participants will engage with challenge areas linked to key domains such as energy, mobility and industry. The final thematic focus and challenge tracks will be confirmed in a follow-up announcement.
Who should join
Students, developers, researchers, innovators, open-source contributors, pilot teams and solution providers interested in collaboration across the CEI ecosystem.
Why it matters
The hackathon supports open-source uptake, fosters interoperability and reuse, and helps turn ideas into scalable solutions for Europe’s computing continuum.
Zenoh 3-Z: Zero Gravity, Zero-Energy Wasted, Zero Overhead Protocol for SDV and Low-Carbon Energy Systems
Participants will design and implement a Jakarta EE application that models and analyzes enterprise domains using the Hourglass Model (Stakeholders, Capabilities, and Standards Group). The analysis and mapping are achieved by leveraging an external Large Language Model (LLM) integrated and augmented using modern AI engineering techniques.
- Concrete scenario: Generate the Hourglass Model for a given domain and use case
- Task: Design and implement a Jakarta EE application that models and anaylyses enterprise domains using the Hourglass Model using an external LLM and agentic tools.
- Inputs: Skeleton Project, OpenAI API Key, Starter Guides, Links to resources
- Expected demo (Definition of Done): A complete, runnable Jakarta EE project
- Skills: Java, Maven, General knowledge of Agentic AI techniques
- Mentor: Ivar Grimstad, Jakarta EE Developer Advocate, Eclipse Foundation
From Code to Continuum: Orchestrating Distributed Applications with OpenSlice
Participants will use OpenSlice to orchestrate a small distributed energy application across a simulated cloud-edge environment. The challenge focuses on connecting 2-3 containerised services, such as energy data generation, processing or optimisation, and visualisation, to show how energy applications can be deployed and managed across the computing continuum.
- Concrete scenario: Orchestrate an energy monitoring pipeline across simulated edge and cloud domains
- Task: Build 2-3 containerized services and use OpenSlice to onboard, deploy, and manage them on a local Kubernetes environment.
- Inputs: OpenSlice documentation, Kubernetes deployment guidance, energy monitoring pipeline concept, and mentor support.
- Expected demo (Definition of Done): A runnable local deployment showing OpenSlice orchestrating the services of the distributed energy application.
- Skills: Kubernetes, Docker/containerization, service orchestration, APIs, cloud-edge concepts, and general software development.
- Requirements: Laptop with a Linux-compatible setup, such as Linux, WSL2, or macOS, meeting OpenSlice’s recommended hardware requirements.
- Mentor: Lefteris Mylonas, COP-PILOT / OpenSlice technical representative.
