#### Agenda

- Frederic
- JupyterLab SSC representative: JupyterLab council members must have received an email with a link to the vote form. The vote will close on October 4th.
- Enforcing GitHub 2FA for JupyterLab GitHub organization members; doing it just after the meeting if no objection.
- [Extension cookiecutter as CC0](https://github.com/jupyterlab/extension-cookiecutter-ts/issues/24); can we move forward?
- [Jason G] I think it makes sense to open a PR, and get contributors to approve the PR.
- [William S] mentioned https://en.wikipedia.org/wiki/WTFPL. Jason commented that CC0 has a stronger legal basis.
- [Jason G] More public domain equivalent licenses: https://en.wikipedia.org/wiki/Public-domain-equivalent_license
- [Release of 3.5.0](https://github.com/jupyterlab/jupyterlab/issues/13064)
- Propose to move forward dropping notification and annoucement feat.
The goal is to release quickly a version that can be tested with Jupyter Server 2
--> No objection
- [JupyterLab Performance meeting after this call](https://hackmd.io/DTEJ5sy9Q9yeW0gYuX0v6A).

- Darian
- [Sign up to host](https://github.com/jupyterlab/team-compass/issues/161) the JupyterLab weekly call
- [Handle deferred processing when `document` is hidden](https://github.com/jupyterlab/lumino/pull/402)

- Jeremy
- New 4.0.0a29 pre-release: https://github.com/jupyterlab/jupyterlab/releases/tag/v4.0.0a29
- Try it on Binder with this gist: https://gist.github.com/jtpio/4e9a3d435d7c3950dc4150c10abbb1d7

- Sylvain
- Empty notebooks
- [WIP PR](https://github.com/jupyterlab/jupyterlab/pull/13141)
- Discussions about the UI / UX: https://github.com/jupyterlab/jupyterlab/issues/13142
- [William S.] cocalc solves this empty cell problem by making so ONLY the backend does the "add 1 cell if empty". It works.
- [Sylvain] ^ this approach proposed by William is considered. It actually requires the same frontend code changes.

#### Additional Discussion

- Jupyter subproject representative voting
- All representative voting needs to have 1) a blank abstain option 2) be rank choice
- How to do rank choice?
- https://civs1.civs.us/ has been used in the past, but feedback from participants makes it seem like it is too heavy for this use
- Google forms as multiple questions (ie. Who is your first choice? Who is your second choice, so on.)
- Google forms as a grid question
- What do other projects do?
- Other platforms were tested, but none have stood out as the best option.

- EuroScipy 2022 feedback
- Poster got lots of interest: 
- No strong complains from users
- Some people took the game at finding differences between Notebook 6 and 7
- JupyterLite and others talks about science with Python in the browser got people very enthusiastic
- Some tutorials were using JupyterLite
- Talk about education displayed a Python introduction example using JupyterLite: https://sportspython.github.io/jupyterlite_test/lab
- CZI EOSS 5 grant [application for supporting JupyterLab 4 / Notebook 7](https://github.com/jupyterlab/team-compass/pull/140) was rejected
- Issue open to list PR candidates for [JupyterLab 3.5.0](https://github.com/jupyterlab/jupyterlab/issues/13064)
- Gabriel and Kulsoom: question for @jweill-aws, could you summarize, give context to the [cell toolbar css rules in lines 14-43 in base.css](https://github.com/jupyterlab/jupyterlab/blob/master/packages/cell-toolbar/style/base.css#L14)
- These are all used for the [cell toolbar](https://github.com/jupyterlab/jupyterlab/pull/12028) added to JupyterLab 4.0 and 3.4.x earlier this year. The toolbar appears on every cell, in desktop and mobile web views, as long as it does not overlap with its content. If you have further questions, I'd be happy to set up a call: please write to me at [e-mail]. — @jweill-aws
- Darian
- `jupyterlab/council` repo

- Vidar
- Question around 3.x benchmarks / performance
- [Related discussion on Discourse](https://discourse.jupyter.org/t/jupyterlab-is-suddenly-slow-has-anyone-got-the-same-situation-or-know-the-solution/15048)
- Isabela
- JupyterLab accessibility call will be fifteen minutes after the scheduled end of this call. All are welcome!

#### Additional Discussion

- @blois
- Portable rich outputs (https://github.com/ipython/ipython/issues/13376#issuecomment-989040562)
- Initial rough prototype: https://github.com/blois/js-module-renderer/
- Basic idea: a mimetype for javascript (or typescript?) that exposes an api to the code to do things like connecting to the kernel, getting a DOM element, creating a comm, etc.
- The api would be very minimal and immutable, e.g., no breaking changes
- https://github.com/jupyterlab/jupyterlab/issues/4902
- Places appropriate for this conversation
- JupyterLab, IPython for implementations
- Jupyter Standards

#### Agenda
- Jason W
- Move triage from Thu 10:00 PDT (17:00 UTC) to Wed 10:00 PDT (17:00 UTC)?
- For the time being, the current time slot seems least contentious, but we should think about other times.
- Use triage to attack backlogs as well, by reviewing older issues weekly?
- PR reviews?
-
- Mike
- Python Logo for Python scripts: blue or as for kernels: https://github.com/jupyterlab/jupyterlab/issues/13023
- One solution for this is in: https://github.com/jupyterlab/jupyterlab/pull/12673
- nbformat, trust and signature: https://github.com/jupyter/nbformat/issues/296
- opinions on ways to sort in PyPI extension manager? https://github.com/jupyterlab/jupyterlab/pull/12866#issuecomment-1232891571
- Darian
- [Update to Lumino 2](https://github.com/jupyterlab/jupyterlab/pull/12992) (needs another rebase, but almost there)
- Governance update:
- By 3 October, we should have the JupyterLab Council fully selected (this does not mean we *stop* here, just that by this point, it should be representative)
- By the same date, we should select our Software Steering Council representative
- If you would like to nominate somebody for the SSC, they must be a member of the JupyterLab Council, they must be willing to accept your nomination, and they need to know that they cannot be both on the SSC and on the project-wide Jupyter Executive Council. So if they would like to run for the Jupyter Executive Council, they should consider whether they are interested in representing JupyterLab in the SSC, because they can only do one or the other.
- @fcollonval has created a form for nominations. Please make nominations by 15 September so that we have enough time to vote.

- Software Steering Committee discussion

- Sylvain

- FYI - since JupyterLab has migrated to CodeMirror 6, some extension will require some significant updates.
- LSP (as discussed previously), but also jupyterlab-git.
- JupyterLab git will require to implement a "merge view" for CodeMirror 6.

#### Additional Discussion
- FYI: ipywidgets 8 was released last Thursday. [Changelog](https://ipywidgets.readthedocs.io/en/latest/changelog.html). If you are having issues with ipywidgets 7 since last Thursday (when doing a pip install), it may be that `pip install ipywidgets` is pulling in the wrong version of jupyterlab_widgets. Please make sure to upgrade to ipywidgets 7.7.2 or ipyiwdgets 7.6.6, since they depend on the correct version of jupyterlab_widgets for ipywidgets 7 (or pin your version of jupyterlab_widgets).
- FYI: nbgrader extension 0.8.0 for JupyterLab as been released: https://github.com/jupyter/nbgrader/discussions/1634#discussioncomment-3445733

- Frederic
- [JupyterLab 3.4.5](https://github.com/jupyterlab/jupyterlab/releases/tag/v3.4.5) has been released
- [2FA enforcement](https://github.com/jupyterlab/team-compass/issues/155) - 2 possibilities
- Enforce it and get people notify they have been removed as collaborators
- Ping people lacking 2FA on private discussion (one has been created by Matthias - github: @Carreau)

We will go for the gentle ping on people - the enforcement is planned by the Jupyter security team by the
end of september. So this left a good amount of time for collaborators to add 2FA.

- Darian
- Lumino 2 [project board](https://github.com/orgs/jupyterlab/projects/4/views/1) and [call for help](https://github.com/jupyterlab/team-compass/issues/158)
- [name=gabalafou] If there are necessary API changes for accessibility concerns, now is the time to outline them; otherwise will have to wait for Lumino 3. [Identify accessibility targets for Lumino 2 #341](https://github.com/jupyterlab/lumino/issues/341)

- Mike
- shout out to JupyterLab Desktop which would benefit from more help, also see https://github.com/jupyterlab/jupyterlab-desktop/issues/477
- unrelated, but the similar effect: https://stackoverflow.com/q/73278038/
- environment selection in JupyterLab Desktop https://github.com/jupyterlab/jupyterlab-desktop/issues/479
- seeking feedback on `.jupyter` for pre-proposal default workspace and setting https://github.com/jupyterlab/jupyterlab/issues/12916
- Vidar: VScode has right-click bringing up last projects
- Perfer having less files than more so that is not too noisy for git users who want to store it

#### Agenda

- Frederic
- PRs reviewer wanted:
- [Use path to extract tmpPath](https://github.com/jupyterlab/jupyterlab/pull/12823) (Darian will review)
- [Update snapshots for challenger commit](https://github.com/jupyterlab/jupyterlab/pull/12820)
- [Add a doc section: automation with Vagrant](https://github.com/jupyterlab/jupyterlab/pull/12806)
I'm not in favor to document automation with a specific tool in the documentation (because there are so many).
So what would be the best approach to add this? Maybe linking to a gist for a given tool?
- Linking to Gists as a policy opens us up to bait-and-switch security issues, where a malicious actor could propose linking to a gist they control, then later updating the gist to do something malicious.
- In general, some problems are:
1. Picking winners, or alternatively bloating our documentation with a confusing array of possibilities
2. Maintaining instructions that no one in the project is using. Perhaps we only accept the contribution if the original author commits to maintaining the instructions, and when it falls out of date and is not updated, we remove it?
- Conversation from the dev meeting indicates preference for other solutions to setting up a dev environment (for example, using conda/mamba tools, etc.). @bollwyvl has some suggestions, for example:
- this one that drives jlab-desktop: https://github.com/jupyterlab/jupyterlab-desktop/blob/master/env_installer/construct.yaml. the actual tool is https://github.com/conda/constructor
- CodeMirror v6 has been merged in master: please test it and report bugs
The follow-up issue is at [#12812](https://github.com/jupyterlab/jupyterlab/issues/12812)
- [Drop of CodeEditor](https://github.com/jupyterlab/jupyterlab/issues/10380) facade: what to keep/remove? e.g. should we move to offset positioning (CM6 does not use {line, col} any longer).
- Max
- improvement to readonly UI
- issue at [#7980](https://github.com/jupyterlab/jupyterlab/pull/7980), draft PR at [#12826](https://github.com/jupyterlab/jupyterlab/pull/12826)
- open to suggestions on design/style improvements
- followup to improved readonly UI: show Toast on failed save attempt
- Original toast issue: https://github.com/jupyterlab/jupyterlab/issues/689
- Max would like to add an existing quality Toast implementation to jlab: [#12827](https://github.com/jupyterlab/jupyterlab/issues/12827)
- eg two reasonable choices of `Toast` component:
- [material-ui Snackbar](https://mui.com/material-ui/react-snackbar/)
- looks good
- super flexible
- con: have to bring in the large mui package, though in theory tree-shaking should mitigate this
- @ajbozarth has been using material-ui snackbar in elyra, and likes it
- [light-toast](https://github.com/xinkule/light-toast)
- small (5 kb as per bundlephobia)
- con: smallish user base
- In [jupyterlab-toastify](https://github.com/jupyterlab-contrib/jupyterlab_toastify), [react-toastify](https://github.com/fkhadra/react-toastify/) is used.
- Recently we had a vote adopting fastui as a component library
- Note that [FAST UI](https://fast-ui.netlify.app/index.html) is not the same as Microsoft's [FAST design system](https://www.fast.design/)
- Real-time sync and the save button
- Some might suggest that RTC might make the save button obsolete
- William suggests that "save" doesn't go away with RTC, because "save" indicates serializing the file to disk, as opposed to syncing with everyone else. In Cocalc, saving by default happens every 30 seconds or when explicitly requested, or when the page closes. A user might want explicitly save because there may be other things watching the file that activate on save, like building a tex file, etc.
- (my (Vidar) understaing is RTC will autosave to disk. There is also currently an auto-save of files in Lab)
- william: In the experimental version of JupyterLab RTC that I just tested it's a mess with clicking save causing warning messages to popup, as if rtc isn't used. Another remark is that save-to-disk WILL sometimes fail (e.g., lost network, filesystem switches to read only, filesystem is full), and it's really important to have a persistent message to user about this.

- Darian
- Voting timeframe: https://github.com/jupyterlab/team-compass/issues/154

#### Additional Discussion

- Report from Scipy 2022
- Tutorial
- 15-20 people there, so about 1/4 of normal attendee numbers. It seemed all tutorials numbers were down at the conference.
- Significant mentions of JupyterLab
- Papyri talk by Matthias demoed Papyri in JupyterLab
- Scipy is going to be planned by NumFOCUS moving forward, may move from Austin in the future.

### Agenda

<!-- If you want to bring up a subject, please add a new list item following that structure -->
<!-- - your name : the subject(s) you want to discuss -->
- Nicolas: A quick presentation of the nbgrader extension port on JupyterLab
- Trung: Integrate `jupyterlab-lsp` into `jupyterlab` [#12534](https://github.com/jupyterlab/jupyterlab/pull/12534)
- Frederic:
- [Yjs multiple import error](https://github.com/jupyterlab/jupyterlab/pull/12715#issuecomment-1168654617)
- Should we add resolution to a single version like for React?
Not needed - using a semver should be good enough
- Look at the webpack config of the example to ensure we are using the commonjs version of Yjs
- [Memory leak fixes](https://github.com/jupyterlab/jupyterlab/pull/12750)
- Does anyone have ideas to improve `IDisposableMenuItem`?
- Kevin
- Open PR: Removing ModelDB in https://github.com/jupyterlab/jupyterlab/pull/12695
- Making Shared Models the only source of truth
- Removes over 1300 lines of code
- Sidequest: making notebook tests run more reliably (it does now)
- Completely avoids the initialization problem (duplicate insertions might cause overwriting of content).
- Proposing this approach instead of https://github.com/jupyterlab/jupyterlab/pull/12359
- Vidar:
- Some PRs for optimizing debugger UI performance [#12751](https://github.com/jupyterlab/jupyterlab/pull/12751) and [#12746](https://github.com/jupyterlab/jupyterlab/pull/12746). Do we have a standard component for virtualized lists / views ?
- Fixed some yarn vs npm registry issues [#12742](https://github.com/jupyterlab/jupyterlab/pull/12742). Was it a consious choice to switch from yarnpk to npmjs? Still needs a manual backport for 3.4.x, which is the only place where this was released as non-pre-prelease.
- Should we also run check on root yarn.lock?
- Darian:
- Some ideas about how to improve workspaces that came out of thinking re: [this issue](https://github.com/jupyterlab/jupyterlab/issues/12644)
- Isabela
- JupyterLab's accessibility call is fifteen minutes after this one. Hope to see you there!
