#### Agenda

- Martha
- Draft PR for settings ui https://github.com/jupyterlab/jupyterlab/pull/11079! I have a list of questions there if anyone could take a look
[Remove dependency on third-party library for ui-components](https://github.com/jupyterlab/jupyterlab/issues/6890)

- Jeremy:
- Feedback on extension authoring https://github.com/jupyterlab/jupyterlab/issues/11075
- https://github.com/wolfv/jupyterlab-dynext is an interesting development to making extension development easier/lower barrier.
- The Jupyter Releaser works well with JupyterLab Extensions :+1: (see cookiecutter config)

- Frederic
- Remove old phosphor class to reduce CSS class stack (goal improve performances by reducing style computation complexity)
- This implies upgrading @lumino packages to the next major version
- Opportunity to update typescript
- Need to wait for IPyWidgets v8 to be compatible to lumino

- Mehmet
- Desktop App upgrade to JupyterLab 3.1.10 along with dev tooling upgrades
- Generates GUI installers for macOS, Debian, Ubuntu, Red Hat, Fedora and Windows
- Bundles a conda environment using Constructor
- GitHub Actions integration
- https://github.com/jupyterlab/jupyterlab_app/pull/191
- Installers at https://github.com/jupyterlab/jupyterlab_app/actions/runs/1235190813

- Konstantin
- JupyterLab LaTeX extension
- [jupyterlab-latex 3.1.0](https://pypi.org/project/jupyterlab-latex/3.1.0/) - federated extension now
- Becoming a maintainer?
- +1 from @jasongrout to you becoming a maintainer for jupyterlab-latex - thanks! @blink1073 - I added you as a maintainer on the repo
- Incoming group of 5 Georgia Tech students working on Computer Science Junior Design Capstone project we proposed. Improvements to LaTeX experience in JupyterLab:
- bibliography tools
- journal templates repository
- drag-and-drop support for plots and data frames from Jupyter notebook into the editor
- simplified uploads of figures into the publications
- UI to quickly create tables, equations and find mathematical symbols
- Discussion: do these features belong in the extension? Or is it something out of scope/should be in separate extension?
- ~~CoCalc/Colab perspective: How do we support notebooks with bibliography (say) in a consistent way...?~~ (I thought this had to do with Jupyter notebooks, but it doesn't.)

- Steve
- [JupyterLab v3.1.12](https://github.com/jupyterlab/jupyterlab/releases/tag/v3.1.12) - First fully automated stable release!
- To learn how to use the releaser, good places are the configuration files for other repo: jupyterlite, voila
- [JupyterLab v4.0.0a9 ](https://github.com/jupyterlab/jupyterlab/releases/tag/v4.0.0a9) and [JupyterLab v4.0.0a10](https://github.com/jupyterlab/jupyterlab/releases/tag/v4.0.0a10) (in progress during meeting)
- [Configurable Probot Binder link](https://github.com/jupyterlab/jupyterlab-probot#configuration) - opt-in, currently used in [JupyterLab](https://github.com/jupyterlab/jupyterlab/pull/11039) and [Lumino](https://github.com/jupyterlab/lumino/pull/229)

#### Additional discussions

- Frederic
- benchmark tests
- [Michal] It seems there is a bit of a jitter due to VMs with different processors being assigned. Would it be a good idea to try to divide the time by some performance score from a third-party benchmark of a processor and show it as "normalized score" in addition to time lapsed?
- Another option is a self-hosted runner that only runs on push, maybe using our project AWS credits. https://docs.github.com/en/actions/hosting-your-own-runners/about-self-hosted-runners
I think the best we can do is deal with the runner differences and have a large threshold for change, which is what this action does: https://github.com/rhysd/github-action-benchmark
Follow up :construction: change the logic to switch to manual to launch more experiments to improve statistical information by comparing the base node of the PR and the head (we want to be independent of the evolution of master).
- Sponsors: What about adding NumFocus sponsor badge on JupyterLab projects as conda-forge does? `jupyter.org` uses this [link](https://numfocus.salsalabs.org/donate-to-jupyter/index.html)
