Agenda

(5 min) Convene, roll call, welcome new people.
(5 min) Intro to @jshinonome from vscode-q project.
Display FINOS Antitrust Policy summary slide
Review Meeting Notices (see above)
(2 min) Approve previous meeting minutes.
- Approved by acclamation.
(3 min) Quick recap on FINOS fork of Kdb Studio and possible collaborations.
(5 min) For vscode-q / Kdb Studio 2 running as VS Code plugins, how to support Authentication plugin API to allow support for Kerberos, etc.?
- https://github.com/jshinonome/vscode-q/pull/40#issuecomment-875691182
- Clarified that there is no need to change node-q.js.
- Just want to generate a token which will be passed in the password field of the regular handshake.
- Proposed solution is that vscode-q plugin would probe for other plugins(!).
- A bit surprising that plugins aren't sandboxed from each other, but does make life easier.
(5 mins) An introduction to KDB Studio 2 Prototype #51 - @ColinEberhardt
- Apparently not too much code required thus far!
- Leveraging of: Monaco (editor behind VS-Code) and Electron (for distribution)
- Additional functionality required to make it a viable replacement for Kdb Studio Classic:
- Excel Export
- Server List Export
- Hot Keys
(5 mins) Is there room for Kdb Studio 2 and VS-Code plugin?
- Mention of Kx Dashboards & Kx Analyst having overlapping functionality but different target audiences.
- @dzmipt believes he will continue enhancing Kdb Studio Classic for a while because:
- More familiar with Java and existing code base.
- More feature rich for now.
- Roadmap ncludes: scatter charts, uploading results to server, word wrap
- Also knows of users kdb who are attached to Sublime / IntelliJ.
- vscode-q goings-on
- Language Server extension that analyzes the source code.
  - Would provide autocomplete functionality.
  - Very early days. Not pushed for public consumption yet.
- Has constructed a simple parser for q, but probably incomplete.
- Can't use any existing parser since he needs more than just a stream of tokens:
  - Information needed by VS-Code: start line, start position, end line, end position
- Might benefit from collaboration with those who've studied the q grammar quite closely.
(5 min) qPython updates?
- Probable name change to qPython3 to release on PyPi.
- Dropped Python 2.x support.
- fastutil.pyx 64-bit changes undergoing testing within Morgan Stanley.
(5 min) Unique Set Size updates?
- Pull request is up: https://github.com/finos/kdb/pull/52
- Only supports Linux.
- /proc is non-POSIX, so not available on MacOS X.
- Happy to accept Pull Requests for wider OS supprt.
- Needs a better understanding of dep.q to load a companion util.q file
(5 min) AOB, Q&A, Adjourn.
- @adavies42 Is working on a native unzip for q.
- Could take advantage of secondary threads.
- FINOS All Community Call and OSSF CFP coming up.
