• All participants in FINOS project meetings are subject to the LF Antitrust Policy, the FINOS Community Code of Conduct and all other FINOS policies.

• FINOS meetings involve participation by industry competitors, and it is the intention of FINOS and the Linux Foundation to conduct all of its activities in accordance with applicable antitrust and competition laws. It is therefore extremely important that attendees adhere to meeting agendas, and be aware of, and not participate in, any activities that are prohibited under applicable US state, federal or foreign antitrust and competition laws. Please contact legal@finos.org with any questions.

• FINOS project meetings may be recorded for use solely by the FINOS team for administration purposes. In very limited instances, and with explicit approval, recordings may be made more widely available.

Agenda

• (5 min) Approve previous meeting minutes.
  • Approved by acclamation.
• (15 min) Demo of KDB Studio 2 https://github.com/ScottLogic/kdb-studio-2
  • Showed how ReactJS Hot Module Replacement allows GUI development while maintaining application state!
  • Other highlights: AG Grid, Fluent UI from Microsoft, Monaco Editor (same as VS Code)
  • Potential next steps:
    • Support for sending selected region / multiline queries to behave more like Kdb Studio Classic.
    • Add kdb-specific actions to the menu bar.
    • Hot keys.
    • Transcript / history of all queries sent to server.

    • UI Automation Test Suite.
    • Reuse Apache-licensed icons from FINOS fork of kdb Studio.
    • Support for non-table output (atoms, dictionaries, lists, etc.)

      • Someone managed to get it running on their Mac at home during the call!
  • Pluggable authentication still to be designed.
    • Perhaps a directory to be probed?
  • New name: kdb Boothroid!
    • https://github.com/ScottLogic/kdb-boothroyd
    • "Q" is the alias for Major Boothroyd from James Bond films.

  • Seems structured logging is a desirable option, but during development, easier to log text strings.
  • An API more of the form .finos.log.debug[x] where x could be a string or a dictionary would be more popular.

Hi @alvin-c-shih

I have noticed Monday, 6 September is Labor Day in the US.

Please let me know if this meeting should be rescheduled?

Kind regards,

James.

[alvin-c-shih]

Sounds prudent. How about the following week?
Thanks!

Hi @alvin-c-shih

I have moved the meeting back by 1 week to Monday 13th Sept at 9:30am ET / 2:30pm BST. This is reflected in the GitHub issue and the FINOS project calendar if you would like to inform the group?

Kind regards,

James.
