Reconstruction and Software Trigger

Continue to put together the fall meeting line up:


Workshop held 2 weeks ago, with 420 people attending at some point (peak ~250 on the Monday, later days ~60-70). Success for the community.

Videos all now posted on YouTube.

Post workshop survey ongoing, full report later.

A few recent meetings:



Kilian noted:

“As in the last year, there is the https://hacktoberfest.com/ coming up in October, encouraging open source contributions from new contributors.

“To mark projects as eligible, we can simply add the hacktoberfest topic to a github/gitlab repository and the “hacktober” label to issues.

“However, I was wondering whether we want to organize an HSF-wide Hacktoberfest event? This would basically be a short event where we present a few introductory slides about collaborative git and then show a few demo issues for participants to work on, then let everyone work on things by themselves.

“For slides, we could take the slides that Aman Goel just recently showed at PyHEP.

“The few events that are listed so far on https://hacktoberfest.com/events/ all seem to be of mostly-global scope, but we might still just add ours.

“As this is a really big global event, the attendance might also be really large, though I’ve heard people dampen the expectation for high-quality PRs. However, I still think this might be a good opportunity for us.”

IRIS-HEP/HSF Joint meeting on Software Citation and Recognition


Planning a possible one-day meeting to discuss topics around how HEP experiments handle citation of software and recognition for software efforts that enable physics publications and other means of disseminating results to the public.

Decided on the date: Wednesday 23 November.

Planning document will be circulated shortly. We will link to relevant discussions, e.g., at Snowmass this summer.
