12 February 2020 Weekly Meeting

• Introductions
• Darian
  • Checked out the Lumino UMD branch to play with examples. Not sure what I was doing wrong...
• Steve
  • Working with Max on icon finalization before cutting final release - some Lumino packages were bumped
• Jason
  • Working on ipywidgets 8. Good news is I think we actually can release a jupyter lab manager that allows us to have ipywidgets 7 in jlab 2.0, so pressure is off for people to migrate.
• Saul
  • RTC grant submitted
  • Weird UI discussion around context menus in outputs
    • Currently react outputs cannot render their own context menus and disable JupyterLab's (in an easy way) b/c Reacts event lifecycle takes place after the default one (this is an underlying React bug/design decision)
    • Suggestion (which I would like feedback on):
      • Can we allow disabling JupyterLab context menus in outputs that have their own context menu?
    • Show output's context menu and prevent lab's global context menu jupyterlab#7670
  • Am going to take a look at performance issues for many outputs in one notebook
    • Like Switching to a big notebook in a tab is slow jupyterlab#4292 (comment)
    • Slow: Considerable slowdown in Firefox once notebook gets a bit larger jupyterlab#1639
    • Long time to switch tabs with many 12 plotly cells
• Max
  • the .icon field in various Lumino interfaces now will accept a LabIcon
    • IRenderer cleanup; normalize icon fields across all interfaces lumino#46
  • Post LabIcon cleanup: Post LabIcon cleanup; migrate last holdouts to LabIcon; fix icon styling jupyterlab#7864
• Aditional discussion
  • JupyterCon 2020 is announced! Berlin, August 10-14. Reviewers are requested. There will be a CFP opening soon for tutorials, talks, and sprints.
  • Scipy 2020 talks/tutorial? Tutorial deadline is 15 Feb, talk deadline is also 15 Feb. Sprints are also there.
    • I (saul) am down to give a tutorial, maybe on extension development including backend/frontend extension?
  • Lumino polling discussion
  • Roadmap / product management and planning for JupyterLab:
    • Given JupyterCon's timing, we should think about releases: JupyterLab 3.0, Debugger 1.0, et alia
