+## News, general matters, announcements
+
+### European Strategy Update (ESPPU)
+
+We have had four of the meetings to gather inputs with the community:
+
+- Detector simulation
+- Reconstruction and Software Triggers
+- Training and Careers
+- Generators (met on Nov 15th)
+
+Data Analysis group meeting will be [Dec. 16](https://indico.cern.ch/event/1486671/), announcement to follow shortly.
+
+*Should we make a specific call for further inputs now? Contact conveners?*
+
+- Yes.
+
+Contact made with all the LHC experiments plus DUNE and Belle II. Generally they seem well disposed to signing the document.
+
+#### Preparing the Draft
+
+Schedule is to have a draft ready in January. Because of the extra time needed by the experiments to endorse, we would like to target 17 January for this to be ready.
+
+Suggestion: as we expect a lot of activity in terms of comments we begin this as a Google Doc. (The intention would be to finalise as LaTeX.)
+
+- Agreed on both points.
+
+### HSF Seminar Series and Compute Accelerator Forum
+
+[Seminar Indico Category](https://indico.cern.ch/category/18810/).
+[Compute & Accelerator Forum Category](https://indico.cern.ch/category/12741/)
+
+Third HSF seminar took place last week: Event Generation on GPUs
+
+Next scheduled seminar dates are:
+
+- 29 January: no topic identified yet, any volunteer?
+    - Sapta: Future colliders (including Key4Hep, 1 detector)
+- 19 February: Verrou, floating point stability check
+- 26 February: 4D reconstruction
+- 26 March: EPPSU
+
+Other experiments? Einstein telescope / GW Low Latency analysis ? Can discuss with Paul.
+
+We are discussing how to optimise organisation of the events - concrete proposal to follo after an SG discussion.
+
+### Advisory Group
+
+Date of the first AG meeting is not yet set. Graeme will send around a Newdle before the end of the year (target end of January). Setting up mailing list now.
+
+### HSF Affiliated Projects and Software
+
+*We need to find people to help do these reviews.* They are fairly lightweight and should not take a lot of time - we are checking usefulness and impact in the community, as well as software development and project best practices.
+
+The [NNPDF collaboration](https://github.com/NNPDF) asked more than a month ago to be included - discussions with generator conveners to find an additional reviewer.
+
+We should also start to approach our previous projects. Volunteers?
+
+Todo: add on the HSF site a page with the list of affiliated projects.
+
+## Activity Updates
+
+Thanks for people who have made their intentions clear, either to stay on or step down.
+
+We anticipate calls for new conveners in most groups: Data Analysis, Simulation, PyHEP, Reco and SW Triggers, Dev Tools and Packaging, Training, Physics Generators. JuliaHEP is TBD.
+
+**We are now seeking nominations for these groups.** Please contact [[email protected]](mailto:[email protected]) (currently Benedikt, Claire, Michel, Liz, Graeme, and Paul).
+
+### Data Analysis
+
+Announcement for Dec 16 ESPPU to follow shortly: [agenda](https://indico.cern.ch/event/1486671/)
+
+### Software Training
+
+We are planning activities for next year, including training events and hackathons, and we hope to have a complete plan by the end of the year-beginning of January 
+
+HSF/IRIS-HEP Software Basics Training - June 18-20, 2025, at CERN
+
+A date for the [12th HEP C++ Course and Hands-on Training - The Essentials](https://indico.cern.ch/event/1477096/) has been set for the week 10-14 March.
+
+### Software Tools and Packaging
+
+Nothing to report.
+
+### Detector Simulation
+
+- Sent a reminder to provide ESSPU input in addition to the one provided at the November 22nd meeting;
+    - Next step would be to start drafting the main points and the text
+- Geant4 Technical Forum to be held on [December 12th](https://indico.cern.ch/event/1482839/)
+
+### Reconstruction and Software Trigger
+
+[Mini workshop on ESPPU input](https://indico.cern.ch/event/1475492/)
+- Had *excellent* speakers giving *excellent* talks.
+    - Recording available - see agenda (glad we recorded it in the end!)
+- Attendance was ~35 people(?) (varied as long 3-hour session). Roughly 50/50 split between ATLAS & LHCb with ~1-2 from CMS, ALICE, ePIC (but key people, e.g. computing coordinators amongst them).
+    - No one from DUNE & Belle II (we believe?). 
+- Tried to summarise the main messages and discussion points, [see here!](https://cernbox.cern.ch/external/public/BcwnnBuIKBeQ4rt/HSF_TriggerReco_ESPPU2025.md)
+- Also advertised beforehand and during meeting [Google doc](https://docs.google.com/document/d/1qNhQ-IjPAmL2-Mx2tXtDAloPLWFprIt9mToa11iQb9M/edit?tab=t.0) for community input, in particular as not much time for discussion. But doc mostly only used by us (convenors).
+- Quick thoughts on some topics that may have not been covered:
+    - Offline computing: In particular challenges of hetereogenous computing technologies? Main focus was all around trigger, with exception of 4D reco.
+    - Energy sustainability: Natural common thread throughout _all_ topics though - is this something we can address generally in the HSF document?
+        - No problem to add a paragraph on this that may be moved in a common section
+        - Graeme: wider issue of environmental sustainability, it's not just CO2
+
+
+### PyHEP
+
+The report to the PSF concerning the sponsorship for the PyHEP 2024 workshop was submitted last week.
+
+### Physics Generators
+
+Work done related to ESPPU
+
+### JuliaHEP
+
+We are starting to plan the JuliaHEP 2025 workshop.

+
+## AOB
+
+### Next Meeting
+
+Next meeting will be [16 January](https://indico.cern.ch/event/1477045/)
+
+- Meeting planned on December 19 is cancelled
+- ESSPU work progress will be followed up by email
+
+
+### 2025 Meetings
+
+[Coordination meeting slots](https://indico.cern.ch/category/7970/) have been booked for 2025 - the usual pattern every two weeks on *odd* weeks of the year. The first meeting next year will be on 16 January 2025.
+
+Reminder: please [sign up](https://docs.google.com/spreadsheets/d/1Z1Z4payCpieOLiVFcC6y9j-KCj71u6xX232LHUgIHfI/edit) for chairing this or one of the future coordination meetings - including 2025!
