The Knowledge Hub is the starting point behind Green Reliable Software Budapest: a practical place to explore green software and adjacent fields through talks, recordings, slides, community resources, and pathways into deeper structured learning.
Whether you are just curious, changing careers, early in your engineering journey, or already practising, start here and follow the topics that matter to you.
Explore the Knowledge Hub
A curated entry point into green software and the fields around it. Learn the language, catch up on community sessions, explore build resources, and decide where you want to go deeper.
Begin with key concepts, guides, and beginner-friendly resources on green software and related topics.
Access challenge briefs, team-formation guidance, templates, speaker sessions, and practical build support.
Explore past event recordings, speaker slides, recap notes, and practical learning material.
See how learning, practical evidence, contributions, and next steps can form a visible skills journey.
Find open challenges, internship updates, incubation opportunities, and ways to get involved.
Connect with practitioners, researchers, founders, partners, speakers, and a growing community.
Recaps for learners
Event recaps are a practical way to get familiar with the field, hear from practitioners, and find ideas for your next step.
A student-friendly introduction to green software foundations: energy, carbon awareness, reliability, maintainability, accessibility, cost thinking, and why these skills matter for the green transition.
A practical student session on what changes when ideas move from classroom, hobby, or hackathon prototypes toward systems that people can rely on, maintain, and improve.
This session explored what changes when code moves from a personal prototype into a system people depend on: reliability, cost, maintainability, energy awareness, accessibility, and the responsibility of production work.
Prepare early for challenge briefs, team formation, practical submission guidance, demo readiness, and post-event incubation pathways connected to green AI and sustainable software.

Track learning, building, contribution, and community access. The Green Passport is a preview of how deeper learning can make progress visible and help people decide what to explore next.
Powered by Data Immigrant Kft.
This is a concept preview, not a formal credential yet. The aim is to make progress visible across learning, project evidence, feedback, community participation, and readiness for future opportunities.
Community timeline
The Knowledge Hub helps people move from awareness into practical learning, open challenges, community work, internships, incubation, and professional networks.
Student onboarding, practical green software learning, preparation for build labs, and access to foundational recordings and slides.
Summer planning, partner conversations, resource development, and early preparation for the next open-source cycle.
HACK4EARTH 2.0 returns with practical green AI, sustainable software, and community-built submissions.
Internship programme activity and incubation of ideas from HACK4EARTH 2025 winners and future teams.
From curiosity to practice
The pathway starts locally: learn together in Budapest, practise through open-source challenges, document the work, connect with practitioners, and build reusable skills. People can enter at different stages and follow the path that fits their experience.
Foundations, recordings, slides, and guided reading.
Labs, small projects, and low-risk experimentation.
Open-source teams, HACK4EARTH prompts, prototypes, and demos.
Mentors, practitioners, partners, and recruiters.
Internships, incubation, and portfolio pathways.
