2020 Planning:

• Communication and Collaboration
  • ACS Workshop
    • Around 50 participants, of which 36 should be participating in the project
    • 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: 
  • 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?
