pySTEPS Hackathon 2025 – “North-of-the-Ardennes Edition @ Château d’Avin”
Call for Applications
Dear pySTEPS community,
The long-imagined “let’s rent a house in the woods and hack together for a week” is becoming reality! From Monday 8 → Friday 12 September 2025 we’ve reserved Château d’Avin (Hannut, Liège province) — a 19-century estate with plenty of space, Wi-Fi and 200-year-old trees just north of the Ardennes.
Key dates
- Applications open: today (28 May 2025)
- Deadline to apply: Monday 16 June 2025, 23:59 UTC+2
- Acceptance emails sent: Friday 20 June 2025
What we’ll work on
- Closing open pull requests & issues
- Prototyping new features (importers, neural nowcasting, docs, tooling …)
- Lightning talks, mini-tutorials & evening demos (board games + local cheese included)
- Final project list set via the GitHub board “Hackathon 2025 – Ardennes Edition”
How to apply
- Outline your idea(s): add proposed issues/features to the GitHub discussion board and tag them ardennes-2025.
- Fill in the application form (5 min): https://forms.gle/Ge7wxq4j3t4TJh526
- Tell us what you’d like to hack on, your skills, and any logistics (dietary needs, accessibility, travel windows).
We will select participants based on:
- Relevance and impact of the proposed work
- Diversity of skills & backgrounds
- Ability to collaborate in an intensive, in-person setting
Unfortunately, completing the form does not guarantee a place. We’ll confirm the final line-up by 20 June and create a waiting list in case of cancellations.
Logistics
- Accommodation, venue & food covered; shared cooking rota in place
- Towels not provided – please bring your own
- Best public-transport option from Brussels: direct IC train Bruxelles → Landen (± 50 min); we’ll organise shuttles to the château
- Solid Wi-Fi promised, but bring large datasets locally just in case
- Climbers: a crag is nearby – pack your gear!
- Tech needs? If you require specific hardware, drop us a line at pysteps.2025@meteo.be and we’ll try to make it happen.
Because the château has only 16 beds (7 en-suite rooms), participation will be by application rather than automatic registration. We’ll select a balanced group that collectively covers the highest-impact tasks for the pySTEPS ecosystem.
Funding
- We gratefully acknowledge the support of the Belgian Science Policy Office (BELSPO) under contract number B2/233/P1/DERISC.
- Are you—or do you know—an early-career scientist who’d like to combine the hackathon with a longer scientific stay at RMI? Let us know! It’s possible to apply for a short-term scientific mission funded by EUMETNET to cover your travel expenses.
Questions or special requests? Email pysteps.2025@meteo.be or note them in the form.
We’re excited to review your ideas and craft a focused, high-energy week of coding, learning and north-of-the-Ardennes adventure together!
