+## News, general matters, announcements
+
+### Letter of Cooperation for CAREER
+
+Eduardo has circulated a [draft letter](https://docs.google.com/document/d/1vs3TSsqPIqkJ_iqxRiqKXc4wyMpO889aTR7a4q8qpfM/edit?usp=sharing) of cooperation for the NSF proposal *CAREER: Exploring Exotic and Rare Processes with New Hardware Trigger Tools at ATLAS* from Ben Carlson.
+
+*The meeting approved the letter.*
+
+### European Strategy Update (EPPSU) 
+
+Computing session at Venice went very well:
+
+- Presentations on various aspects during the 3-hour parallel session
+- 2 talks during the plenary session, one about HL-LHC, one about future beyond it
+  - Parallel session slides: <https://agenda.infn.it/event/44943/sessions/33815/#20250623> and <https://agenda.infn.it/event/44943/sessions/33818/#20250623>
+  - Plenary session slides: <https://agenda.infn.it/event/44943/sessions/32614/#20250626>
+  - Plenary also has video save to YouTube here: <https://www.youtube.com/live/7MtB0CXIr_Y?feature=shared>
+
+WLCG noted that current projections for computing needs will not fit into "flat budget" - so more software R&D is needed. Tommaso also noted that little concrete progress had been made with careers.
+
+Our EPPSU submission has been submitted to EPJ-C.
+
+### IRIS-HEP Steering Board
+
+Caterina Doglioni, as the new HSF representative at IRIS-HEP, is preparing [slides](https://docs.google.com/presentation/d/1zrV0P_kIDxwDS9bZsYYE6S3HXPUsaEXfKkQUYr8EjmA/edit?usp=sharing) from the HSF. The presentation is scheduled for July 15.
+
+### HSF Seminar Series and Compute Accelerator Forum
+
+Venice workshop report tentatively scheduled for September. dCache project have signalled interest in presenting in a future Seminar. A seminar on HS3 will be organised also in the future.
+
+How to format "seminar" on Venice symposium?
+
+- Engaging discussion, or..
+- (unbiased) report of highlights and key statements?
+- Suggest inviting Borut and/or Tommaso for this to give a summary of the outcomes and main messages (and they may prefer October, after the briefing book?)
+
+HSF seminar conveners are reachable at <mailto:[email protected]>
+
+- Please send your suggestions for next seminars, **particularly from the activity areas**.
+
+### Steering Group
+
+Eduardo Rodrigues has been elected the new HSF Steering Group chair, effective 1 July. Congratulations to Eduardo and thanks for taking on this important role!
+
+A HUGE thanks again to Graeme for being SG chair for the past year and for all his (long-standing) impactful commitment!
+
+- There will be a SG meeting soon in July. Then back in September.
+
+### HSF Affiliated Projects and Software
+
+We will work on a new version of the project affiliation (streamlined, no bronze, silver, gold) - will be circulated for discussion when it's ready.
+
+## Activities Updates
+
+### Software Training

+    - Finishing the chapters, giving some consistency between examples and exercises
+    - We will try to develop a bonus chapter on Grafana dashboards
+    - Switching from "old" Carpentries style to JupyterBook
+
+- [Deep Learning Train-the-Trainer Workshop](https://indico.desy.de/event/47263/) - Sept 15-19.
+    - Organized by the HSF and ErUM-Data-Hub
+    - In-person in Potsdam
+    - Registration is still open! Deadline: August 4. 17 people registered!
+
+### PyHEP

+    - More than 30 participants confirmed
+    - 12 abstracts accepted
+    - Talks in the mornings, discussions & hacking sessions in the afternoons

+
+- [PyHEP users (virtual) workshop](https://indico.cern.ch/e/PyHEP2025) (October 27-30, 2025):
+    - Need an agenda event created
+    - Planning the (invited) talks:
+        - Already have one: rabbit - TensorFlow based fitting library (similar to CMS Combine)
+        - Columnar analysis with Awkward Array and Uproot 
+
+- PyHEP topical meetings:
+    - "NanoAOD and RNTuple - Uproot" talk-discussion involving the analysis and xpog people from LHC experiments lead by Andres Rios-Tascon
+
+### JuliaHEP
+
+- [JuliaHEP 2025 Workshop](https://indico.cern.ch/event/1488852/) will be held at Princeton from July 28 to 31.
+    - Final registration deadline: July 7
+    - 40 people registered so far

+
+### GSoC program 2025
+
+- 26 GSoC projects ongoing
+    - 8 related to EP-SFT
+    - wide variety of topics: ML, green software, IT, compression...
+- Admins don't have much news - good sign?
+- Midterm evaluations for shortest projects approaching (Mid-july)
+    - mentors should contact admins if they want an extension
+    - should also not be afraid to fail students when it doesn't work out
+- We'll invite the students to the SFT induction event next week. (Danilo gives a nice overview of computing in HEP).
+    - <https://indico.cern.ch/event/1564721/>
+    - will send out mail soon. Mentors: please forward to gsoc students
+- If someone is willing to give a brief introduction to the HSF (and maybe the training program) that would be very welcome.
+    - Training group have some suitable material, will arrange details offline
+
+### Event generators
+
+- Event generators for FCC-ee/Higgs factory:
+
+Enrico Bothmann will talk about Sherpa for FCC-ee on July 24th at 17:00 CERN. Indico agenda will be available soon. 
+
+## AOB
+
+### Physical Constants / HEPdata Library
+
+Reminder: we are proposing a C++ header-only library that defines physical constants and some salient HEPdata in a lightweight, easy-to-use manner. Also taking into account versioning.
+
+We are discussing a next meeting for this, probably next week. Please let Graeme know if you'd like to be kept in the loop.
+
+### NGT/openlab Optimising Floating Point Computation
+
+Very interesting workshop - a particular highlight was work on emulating FP32, FP64 with lower precision types (like bFloat16).
+
+Enrico Bothmann also gave an excellent talk explaining how the mathematics of event generation give rise to stringent requirements on numerical precision.
