  • Used the 4 maxims of cooperative linguistic communication to design a way to plan, guide, and quantify progress on docs. It relies on iterative work carried out through small, actionable tasks where each task is planned around fixing things that fail relative to Manner (“is this clean, clear, non-redundant, non-ambiguous, orderly, accessible, etc.?”), Relation (“is this relevant here?”), Quantity (“is this too much/little here?”), and Quality (“is this true, accurate, up-to-date, …?”). Relation integrates nicely with Daniele’s Diataxis categories: Diataxis forces you to assign to each doc just one main goal (out of Tutorial, How-to guide, Reference, and Explanation), and Relation forces you to trim that doc further so its content is all relevant relative to that goal.
  • Carried out multiple tasks related to especially Manner (projects “First pass”, “Improve UX”, “Clean up”, “List all”) and Relation (project “Modularize all”).
  • Proposed a refactoring PR for improving parallelism when starting/stopping instances within the provisioner worker #13499

Nice work there.

Feedback is that when trying to submit bugs, I have to use launchpad but the code itself is in github? Thats double the effort to contribute.

Even broader thoughts are what are your opinion on how we can shorten the distance between developing juju inside Canonical and the external community/ies?
