Hacking is building things that you always wanted to have but no one has built it yet. It's to come up with an amazing idea and work tirelessly on it. It is to fail, fail again and fail better. Try out new things and learn while doing that. It's to work together, collaborate and build things that are innovative. It is to be a better programmer.
With that spirit, 24h Education Hackathon is conducting a hackathon - EducationHack and invites all developers and hackathon enthusiasts to participate in an interesting and engaging hackathon.
For more details you can always head over to http://educationhack.nl where you can already find the case questions where you will be working on during the hackathon.
