The FOSS FEST 2025 Hackathon, scheduled for February 21-22, 2025, is a free event bringing together students from multiple locations including India, Cambodia, Germany, Namibia, The Netherlands, and the UAE. Participants will work in teams at their local universities and libraries, to compete for daily prizes of 2000 euros. The event, coordinated by OS-SCi and FOSS partners, features live-streamed masterclasses from notable speakers covering topics like Digital India, Ubuntu Touch development, Odoo, Linux Development, Microservices, and Kubernetes. The hackathon offers valuable opportunities for students to engage with the FOSS community, build their programming reputation, and potentially win prizes, while universities can showcase their innovation and connect with international open source communities.
