+### European Strategy Update (ESPPU)
+
+Discussion on HSF inputs.
+
+See [slides](https://indico.cern.ch/event/1355758/contributions/5708314/attachments/2945044/5175250/HSF%20Inputs%20from%20European%20Strategy%20Update.pdf) attached to the agenda.
+
+As said in previous meetings, HSF input to ESPPU is important
+* Input to last ESPPU was based on CWP: good time for CWP update
+* To reflect the community view, the key actors must be the HSF activities (and thus the activity coordinators!)
+* Deadline is tight: end of March 2025. Must start immediately our work to prepare the document that we'll submit. Timeline proposal:
+    * Now -> beginning of January: activity meetings to get the community feedback on the topic identified
+    * January : writing of chapter drafts
+    * Feb 1-15: assembling of chapters, first paper draft
+    * Feb 15 - March 1 : draft circulation and finalization
+    * March: community endorsement (something like what we did for the CWP, asking for people to sign it)
+
+- Claire - meetings organised by activity areas?
+    - Yes, we have to delegate this down to the activity area coordinators
+- Tommaso - are these meetings in addition to the seminar series?
+    - Yes, the work required doesn't fill well into the seminars
+- Alex, yes the training WG can contribute
+- Eduardo, this would be a much shorter paper
+- Michel, not starting from zero, we have a lot of experience already and can do this on a much shorter timescale (original CWP was ~18 months)
+- Patrick - will try to schedule a mini-workshop to see where we are with the development tools and prepare input to the document
+    - Graeme: great idea, probably focus on-line, 1/2 day, meetings
+- We shall do "checkpoints" with the groups in these coordination meetings (don't need extra ones!)
+- Experiments are preparing their inputs, do we take these into account?
+    - Ideally yes, as people are in the experiments we hope this is not a problem
+- Stephen M. (generators): ok with the proposal
+
+Action: Michel/Graeme will contact the relevant activities with the plan and ask them to get started
+
+Length?
+
+- 1 page too short
+- 10 pages too much
+- Probably the target is 3-5 pages per activity
+
+Mainly software matters, but sociological risks should all be covered.
+
+### HSF Seminar Series
+
+The seminar series is up and running:
+
+- [Julia in high-energy physics: a paradigm shift or just another tool?](https://indico.cern.ch/event/1452314/), Uwe Acosta
+- [Julia as a Statically-Compiled Language](https://indico.cern.ch/event/1462252/), Jeff Bezanson
+
+We would now like to advance the planning for the next events. Scheduled dates would be:
+
+- 30 October (it's quite soon...)
+- 27 November: Generators?
+  - Stephen M. checks with the people involved
+- 29 January
+- 26 February
+
+Please coordinate with Michel and Benedikt!
+
+## Steering Group News
+
+### Advisory Group
+
+The [Advisory Group mandate](https://hepsoftwarefoundation.org/organization/advisory-group.html) is published. Invitations have been sent to the large HEP experiments, WLCG and the theory community (MCnet).
+
+### HSF Affiliated Projects and Software
+
+The description of [HSF Affiliated Projects and Software](https://hepsoftwarefoundation.org/projects/affiliated.html) is now on the website. It motivates the activity and sets out some of the parameters for things like reviews, defining requirements and providing reference implementations.
+
+The actual [guidelines for projects](https://hepsoftwarefoundation.org/projects/guidelines.html) are on a separate page.
+
+- Do people know of projects (theirs or others) who would like to trial the process of becoming an affiliate?
+
+## Activity Updates
+
+### Data Analysis

+- Next meeting on Oct 28: https://indico.cern.ch/event/1461088/
+  - focused on Scipp (https://scipp.github.io/) and ragged data. 
+  - Room also booked at CERN
+  - email to DAWG sent yesterday (feel free to advertise to interested communities!).

+
+### Detector Simulation
+
+Geant4 Collaboration meeting is ongoing this week in Catania; an open session dedicated to user presentations took place today
+
+### Reconstruction and Software Trigger

+
+The report of the PyHEP.dev 2024 workshop (Aachen, 26 Aug - 30 Aug) is [published on the ArXiv](https://arxiv.org/abs/2410.02112). It is a community-driven document, as nearly all participants contributed to the paper.
+
+### Physics Generators
+
+*GPUs and Generators*, will try to arrange something for the HSF Seminar series.
+
+### JuliaHEP
+
+We had the [JuliaHEP 2024 Workshop](https://indico.cern.ch/e/juliahep2024) last week.

+- Overall about 20 talks from HEP, astroparticle and industry (ASML)
+- Hackathon sessions involved a lot of discussions on Lorentz vectors and particle interfaces, as well as ROOT building/bindings and possible training material
+- Discussion of the most important next topics for [JuliaHEP](https://notes.desy.de/rp4Rg15ySZqlhCEzFGrK2Q?view) was had at the end of the workshop
