We’re rethinking the conference #Hackathon format by launching a HaCLAthon (C=Collaborative, L=Long-term, A=Asynchronous) [1] for the #IOER 2026 conference. [2]

The goal is a living #JupyterBook that becomes a citable publication with a DOI. Here is the stack I built to make it actually work:

1. The Problem: Jupyter Notebooks are great for #DataScience, but a difficult for collaborative #Git diffs and non-technical domain experts. Solution: We use #Jupytext to maintain a bidirectional sync between .ipynb (for code) and .md (for text stories).

2. The Problem: Inviting external contributions usually means a security/privacy black box if you use 3rd-party CMS brokers to link into Github/Gitlabs. Solution: I deployed a self-hosted #Golang OAuth broker to handle the GitHub handshake on our servers as a microsservice. 100% #DSGVO compliant and sovereign. [3]

3. The Problem: We want domain experts to write, but we don't want to force them to learn Git. Solution: Integrated a browser-based visual editor (#DecapCMS/#SveltiaCMS). Edits enter a Kanban-style editorial workflow as PRs. We review/merge on Github, and our #GitLab CI/CD builds the book.

4. The Result: Developers get #Jupyter4NFDI or local #Docker environments. Writers get a WYSIWYG browser editor. Everyone gets listed as an author on a persistent scientific artifact.

Documentation is also about building inclusive pipelines!

Want to contribute a "hack" or spatial data story?
We are looking for contributions on urban resilience, circularity, and land-use change. 🌍

Our proposal for initial funding for a Jupyter NFDI Base Service (Jupyter4NFDI) has been accepted.

The project aims to simplify access to Jupyter Notebooks within the National Research Data Infrastructure (NFDI). The initiative seeks to enable a unified approach to computational, reproducible research.

The basic service initiatives #Jupyter4NFDI, #DMP4NFDI and #KGI4NFDI have submitted applications for funding. At its meeting on 12 April, the Consortia Assembly (KV) of the #NFDI Association voted in favour of funding the three applications.
Congratulations and many successes with the realisation! 👏
