Hi Everyone,

This is my attempt at writing a weekly summary of our video meeting we have each
Tuesday. I’m using the notes that have been taken during the meeting by the
collective effort so the quality of the section depends highly on the quality of
the notes taken.

Weekly news by organization

These contain a statistics and short summary of all opened issues/pr that were open/merged.

Project management (Jamie)

  • JupyterCon CFP deadline extended to March 14 - looking for additional Data
    Science and AI submissions
  • Fernando submitted the foundation report last Weds - great teamwork at
    Berkeley finishing the report
  • Participated in JupyterCon speaker office hours on Saturday- good questions
    and topic proposals posted
  • Binder planning session occurred on Sunday- incubator showcase is still down-
    ML thread
  • Visiting UC Davis tomorrow morning for Reproducible Research in Jupyter lesson
    on publishing and sharing
  • Working this week with Min & Carol on release schedule/history and other
    metrics (time permitting)

IPython

There are some disagreements on a bringing backs hooks for the readline
interface (https://github.com/ipython/ipython/issues/10364). We would would like
people to read and pitch in if they have the use (or not).

The IPython team is participating in the
Docathon and we are writing docs !

Matthias is working on Async/Await in the REPL (just exploring simplifying
workflow), allowing bare await at the top level in the REPL.

Notebook (Grant, Thomas, Jason) (+ Mike)

nbconvert (Mike)

  • decent amount of progress on unicode coverage locally
    • have more or less given up on fixing it on travis
  • generating json for traitlets & nbconvert as a service
    • discussion after last week about generating a jsonschema for
      automatically generating UI for configurable parameters

Services - kernel gateway, docker-stacks (Pete, Min)

  • Thanks @Min R for fixing the session deserialize problem when switching to
    notebook 5.0 https://github.com/jupyter/kernel_gateway/pull/228.
  • There’s a PR out to remove the KG specific activity tracking API in favor of
    the one in notebook 5.0 (https://github.com/jupyter/kernel_gateway/pull/230).
    It’ll be a breaking API change, and so the next KG release will be 2.0.
    (Another one of the session deserialization bugs popped up in the PR test run.
    It could be that I undid part of Min’s fix. I’ll look into it.)
  • I started looking at making KG token auth match the scheme used in notebook.
    KG can’t reuse the code per se because it still relies on cookies after the
    one-time token is authenticated. However, I think KG can support the token in
    the URL query string and on websocket connections like notebook.

Dashboard and related extensions (Pete)

  • There are PRs waiting on jupyter/dashboards,
    jupyter-incubator/dashboard_bundlers, and jupyter-incubator/contentmanagement
    making them all Notebook 5.0 compatible. I’ll merge the PRs after 5.0 final
    release and make new releases of each.
  • From mailing list: jupyter-incubator/showcase is not working (and probably
    hasn’t been for some time). See if it’s worth resurrecting else point folks to
    the doc about how to install locally.

JupyterLab (Steve, Darian, Chris)

[1]: A tool for managing multiple npm packages in a single github repo:
https://lernajs.io/

ipywidgets (Jason, Sylvain) (+ Brian, Cameron)

We released ipywidgets 6.0, and have been following up on feedback from the
community. Things seem to be going fairly well, and feedback from the community
is pointing to some high priority items to work on next (like an OutputWidget in
the web context, https://github.com/ipython/ipywidgets/issues/986).

  • We have released jupyter-sphinx 0.1.0

We have released a bunch of downstream packages (pythreejs, ipyleaflet, ipympl)
following the 6.0 release. Also, we’d like to especially call out a nice package
from Maarten Breddels: ipyvolume (https://ipyvolume.readthedocs.io/en/latest/)
with live widgets in the documentation, including a VR view
(https://ipyvolume.readthedocs.io/en/latest/vr.html). We’re working on migrating
widgets to the newest phosphor packages and updating the widgets to work in the
most recent JupyterLab (https://github.com/ipython/ipywidgets/pull/1122).

JupyterHub (Min, Carol)

Lots of productive discussion happening during our Berkeley visit this week!

Thanks you for reading, and thanks a lot for those of you who wrote sections
with full sentences and all the details. Any help to put this document in form
before sending it to the mailing list is welcome. It’s a collaborative document
so anyone can pitch in.

As usual if you have any questions/feedback/corrections like sections too long,
to short missing informations, your input is welcomed. We’ll keep these summary
for a couple of weeks to see if you find them useful.

Thanks.
