News, General Matters, Announcements

Email from github:

Hi there, You are receiving this email because you are an admin for HSF in GitHub that is using the GitHub Code Quality public preview. GitHub Code Quality moves to general availability on July 20, 2026. After that date, Code Quality usage on your enabled private repositories will be billed at $10 per active committer per month plus usage-based consumption for the AI-powered capabilities. Right now, our data is showing that you have 1 repositories with Code Quality enabled, across the following organizations: HSF

Note: It concerns a particular GitHub repo within the HSF organisation (not the HSF website repo). Since no billing information has been shared, we shouldn’t be getting any unexpected charges.

Steering Group & Advisory Group

No news at this point. A SG meeting will soon take place.

WLCG/HSF Workshop 2026

• 2-6 November 2026 in Bologna, Italy.
• Registration is up, abstraction submission open. Do consider participating in this nice joint event!

HSF Affiliated Projects and Software

Status at https://hepsoftwarefoundation.org/projects/projects.html - unchanged, 6 projects affiliated.

Reviews in progress, being finalised:

• NoPayloadDB Conditions Database
  • Status: Delay due to low availability of reviewer.

Other potential projects previously brought up:

• ACTS - Caterina to follow up.
• Herwig (we already have Madgraph/Pythia) - we will hear from Christian Gutschow and James Whitehead (MCNet reps).
• Phoenix - the author is happy to join.
• Rivet.

SG will find volunteers to contact these projects from GSoC list of projects this year:

• Clad
• Omnifold (Saptaparna will contact authors)
• PODIO (future collider frameworks - Michel will contact authors by the end of August)

Todo: We should actively assign people to projects and document who is assigned.

AI in Contributions to HSF Repositories

“AI Statement” for contributors to HSF repo

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. There is an ongoing discussion 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”.

–> Claire would like to volunteer to give this a first go with a PR based on the feedback in discussions (could start with a webpage suggestion, but making a CONTRIBUTING.md file sounds like a good idea!).

Forum discussion: Towards common responsible AI-assisted coding guidelines

Wed July 29th, 15h30-17h30: https://indico.cern.ch/event/1705480/

• Announced to HSF Open Forum + HSF Advisory Group.

Current status:

• Working on dedicated talk:
  • CERN IT to give 10’ talk on security principles.
  • Discussing short pitch on sustainability.
• Some material already uploaded to encourage contributions.
• Various communities hopefully circulating the announcement of the event.
• Will send another reminder to AG along with a survey on training needs targeting individuals.

HSF Seminar Series and Compute Accelerator Forum

Planned HSF seminars:

• 22nd July: Seminar on “Green Software Engineering” by Michael Sparks, Manchester.
  • Note: Exceptionally not on the last Wednesday of the month.
• 30th Sept: Seminar on “assessing sustainability of AI” by Sophia Wilson (SAINTS Lab, University of Copenhagen).
