Hacktoberfest Hack Day Esbjerg
Join Cod3rs and IT Women Esbjerg for a Hacktoberfest Hack Day - a one-day, in person event, celebrating open-source culture and modern tech.
What is it about?
Our goal is to create an inclusive space to work on open-source projects, learn about open AI tools, share knowledge, and collaborate on real code. Whether you are a seasoned professional, a curious student, or a complete beginner without a clue where to start, this is your chance to build and ship something real using open-source or open-weight AI.
What to bring?
All you need to bring is a laptop, a charger, and some enthusiasm. Have an exciting idea? Awesome! Still missing one? No worries, we’ll have challenges ready at the door so you can borrow an idea.
How does it work?
Once you have decided which idea to pursue, you get to spend the day turning the idea into a working project. Fuel it with pizza, coffee, and snacks. Submit through OrganizerHQ Challenges and go head-to-head in the Best Open-Source AI Project challenge. First pull request or fiftieth, you’re in the right room!
Sounds scary? 👻
Don’t worry, even though the event lands on Halloween, there is nothing to be afraid of. You can join ranks with other people, and form teams to help each other (don’t let merge conflicts haunt you though). Plus, our friendly volunteers will be on hand all day to help whenever you get stuck.
Share your pics and screenshots with #Hacktoberfest. Happy hacking!
Challenges
Best Use of Gemma 4
It’s time to see how much you can build with a lightweight, open model. Gemma 4 packs multimodal intelligence into an open-weights model that you can access through the Gemini API. So, what can Gemma 4 bring to your project?
- Multimodal Experience: Work with text and images to create an assistant that understands more of what users share.
- Focused AI Tools: Build a focused AI tool for learning, creativity, productivity, or your community.
- Rapid Prototyping: Experiment with an open model while using the Gemini API to move quickly from an idea to a working prototype.
Bring your idea to life… what will you build with Gemma 4 today?
Best Open-Source AI Project
Build an original project that uses open-source or open-weight AI as an important part of how it works. Teams could create an agent skill, build with an open-weight large or small language model, or build or adapt an open-source model harness. These are examples within one challenge, and teams may combine them.
Open-source or open-weight AI must be an important part of the project.
The project must be published in a public GitHub repository and use an open-source license.
An agent skill must comply with the Agent Skill Open Standard.
A model-harness entry must include an original implementation or meaningful changes to an existing open-source harness.
Submissions aren’t open for this event.
