About the Code Fest

The ROAR-NET Problem Modelling Code Fest will be a 48-hour online coding event open to all present and future ROAR-NET members around the world. Planned activities include:

• Problem structuring

Extensive use of the software and training materials developed for the First ROAR-NET Training School will be made throughout the event.

Participation

Team registration will become available soon.

Call for Hubs

Prospective participants are invited to organise physical hubs, for example at their institutions. A hub will typically be a room equipped with tables, power sockets and internet connectivity where local teams can gather to participate in the event. Video conferencing facilities are a plus, but are not strictly required. Hub organisers are solely responsible for deciding on the teams they are willing to host.

Hubs can be set up almost anywhere in the world. The programme of the event will take the corresponding time zones into account.

If you would like to organise a hub, please apply by sending email to code-fest@roar-net.eu with the following information:

• Name and e-mail address of the hub organiser
• Institution hosting the hub
• Hub capacity and/or expected number of participants

The first two items will be published on this page if the hub is accepted.
