News, general matters, announcements

• Have all Activity Area (AA) conveners updated their pages with present and past conveners?

Steering Group & Advisory Group

• Co-organising the next WLCG/HSF Workshop, 2-6 November 2026 in Bologna: Converged on draft schedule of HSF parallel sessions.

• Finalising a significant rework of the Affiliation programme based on gathered experience from recent reviews and from community feedback. One last update to be online on the website shortly.

HSF Affiliated Projects and Software

Status at https://hepsoftwarefoundation.org/projects/projects.html - 5 projects affiliated as of today.

List of reviews in final stage of community feedback:

• DIRAC

Reviews underway:

• NoPayloadDB Conditions Database

Do not hesitate to discuss around you to identify relevant projects/libraries that could engage with the affiliation programme. AA conveners are in an excellent position to help us identify which projects to prioritise to join the affiliation programme.

Thank you very much to those who accepted to act as a “reviewer” or spontaneously put themselves forward. This is super appreciated; it makes all the difference.

AI in contributions to HSF repositories

Feedback still welcome: So far HSF repositories do not provide any statement on AI-powered/-helped contributions, and we are starting to get some. On occasions we can be flooded by not-to-useful contributions. This year an “AI statement” is strongly suggested in GSoC proposals. We should do something similar.

Please add your thoughts at https://github.com/HSF/hsf.github.io/issues/1919.

Suggestion to update the website how-to with a statement on AI and how we will be dealing with “spam”.

HSF Seminar Series and Compute Accelerator Forum

Recent HSF seminars:

• Seminar by Kati Lassila-Perini (chair) on ICFA Data Lifecycle panel best practice recommendations, 29th April:
  • Interesting discussions, attended by ~10ish people (lower than usual).
  • Many thanks to Caterina and Stefan for the help organising & chairing!

Planned HSF seminars:

• via Software Tools & Packaging AA & HEP Packaging Coordination: “Packaging focused HSF seminar together with possible contributions from EIC and FCC people”

(Thanks to the activity groups for coming to us with seminar ideas and speakers!) HSF seminar conveners are reachable at hsf-seminar-conveners@googlegroups.com. Please send your suggestions for next seminars.
