Hello everyone, and welcome back for the AstroInfo Hackathon Week (Nov 3–7)! Most of you were here last week for the school — great to see you again! For the few new arrivals, welcome aboard 🚀
This week is all about hands-on collaboration, creativity, and coding. You’ll work in teams to develop and polish scientific software projects — and hopefully bring them to a publishable stage!

| Monday morning | Hack presentations - Gosia, Marc & Paolo |
| Monday 13:30 | Group formation |
| Monday 14:00 | Hackathon begins! |
| Every day 10:00 | Morning tag-up session (conference room) |
| Every day 18:00 | Evening wrap-up session (conference room) |
| Every day 13:30–14:00 | Optional breakout discussions (paper board to request topics) |
| Friday morning | Final project presentations + wrap-up |
Each group will have max 5 minutes for daily wrap-ups — short, sharp, and focused.
Your main goal: ➡️ Reach the minimum requirements for a JOSS submission, and publish your code on GitHub.
If your project yields interesting results: ➡️ Consider extending it toward a scientific letter, poster, or conference talk.
We’ll also look for volunteers to lead follow-up working groups to finalize promising projects beyond this week.

You can choose CPU or GPU nodes when starting a new server.
For the hackathon, 3 machines with 12 GPUs total are reserved. These machines also have excellent CPUs — feel free to use them for both GPU and CPU-intensive tasks.
- Monday 18:00: Visit of the Observatory → Followed by stargazing session after dinner 🌌
- Wednesday 20:45: Café Science (in French)
- “My PhD in 5 minutes” – volunteers welcome!
- AstroInfo Quiz – propose your questions on Discord
- Round Table – suggest discussion themes on Discord
- Wednesday 13:30: Group Photo, in front of the main building.
You are welcome to use AI assistants (such as ChatGPT, Copilot, or others) during the hackathon — especially for:
- exploring documentation or libraries,
- writing boilerplate or refactoring code,
- generating or proofreading text (e.g., README, docstrings).
When you do, please mention it explicitly in your project documentation. A simple example:
“Parts of this code and documentation were drafted or refined using ChatGPT (OpenAI GPT-5), under the supervision of the project authors.”
Transparency about AI use is part of good scientific practice — and helps others understand and reproduce your workflow.
The hackathon is about experimenting, learning, and building together — not just producing results. Collaborate, share ideas, and enjoy the process!
Let’s make this week both productive and fun ✨
This README was drafted by Julien Zoubian with the assistance of ChatGPT (OpenAI GPT-5) for editing, structure, and English phrasing — under Julien Zoubian’s full supervision and revision.
