      • Joseph Schwarz offered help as instructor for the workshop
    • Issue Tracking platform for the community
      • During the ACS Workshop this will be discussed in the "ACS Issue Tracking and Main Problems" section
      • One alternative is to offer a public project for official JIRA
        • This public project would be public for read, but authorized login to create/comment/etc.
    • Fork/Branches on public repository
      • Workflow is similar to GitHub:
        • Fork of the branch and work in your user's version of the repository
        • To be defined how to bring changes back to ALMA. To be discussed in "ACS Issue Tracking and Main Problems" section of ACS Workshop
    • Community Chat
      • Slack as an option
      • Tomas Staig will check possibilities
    • Docker Hub
      • Section in the ACS Workshop to discuss the official docker image
  • Re-design Notification Channels
    • A bit delayed
    • Consider Kafka and Akka Streams as additional possible candidates
  • BulkData
    • As discussed in pending action items section
  • Monotonic Clock:  ICT-16764 - Getting issue details... STATUS
    • Will be tested soon for ALMA. If it works it would be set up as default
    • If it is used, then other projects should check if it affects them in any way

Other institutions plans and proposed topics

  • Joseph Schwarz comments that it would be useful to avoid compiling ExtProds when no changes have been made between 2 releases
    • Igor Oya  and Torsten brought information about the RPMs being prepared at CTA by DESY
      • They will look into this internally and try to provide the current information to ALMA
      • ALMA will look into this and try to add dependencies from OS and others

Any other business?
