JupyterLab のすべての設定は、メニュー [Settings]-[Advanced Settings Editor] を開いて System DefaultsUser Preferences で上書きすることで可能です。
設定はユーザー セッティング ディレクトリに保存され、標準の保存場所は $HOME/.jupyter/lab/user-settings/ です。(標準の保管場所を理解していれば、他の環境に設定のコピーが可能になり、毎回設定する手間が省けます)

Project Jupyter は IPython から 2015 年に分離されて始まったプロジェクトですが、IPython が最初に公開された 2001 年から数えても 10 年以上の歴史がある大きなプロジェクトなので、サブシステムごとに膨大なドキュメントが存在しています。
ひとまず、ドキュメントタイトルだけでも整理してみました。

.NET Interactive は 2019/05/16 にオープンソース化された Try .NET(*1) を .NET Notebooks Preview 2 で名称変更(*2)したものである。Preview 2 では C#, F#, PowerShell に加えて nteract のサポートが追加された。

*1 Try .NET は 2017 年 9 月に Microsoft Docs で公開されたときは Azure コンテナで実行していたが、その後 Blazor と Web Assembly の実装に置き換えられた。(Blazor - Web ブラウザで動作する .NET Core 環境 )
*2 Try .NET は 2020 年 2 月 6 日の .NET Notebooks Preview 2 で正式名称が .NET Interactive に変更された。


.NET Interactive は 2021/03/04 現在 C#, F#, PowerShell, JavaScript, HTML, T-SQL をサポートしています🤤

.NET Interactive now ships with T-SQL support in addition to C#, F#, PowerShell, JavaScript, and HTML.

(pyJupyterLab) $ jupyter lab build
[LabBuildApp] JupyterLab 3.0.16
[LabBuildApp] Building in /home/tomoyan/pyJupyterLab/share/jupyter/lab
[LabBuildApp] Building jupyterlab assets (production, minimized)
Build failed.
Troubleshooting: If the build failed due to an out-of-memory error, you
may be able to fix it by disabling the `dev_build` and/or `minimize` options.

If you are building via the `jupyter lab build` command, you can disable
these options like so:

jupyter lab build --dev-build=False --minimize=False

You can also disable these options for all JupyterLab builds by adding these
lines to a Jupyter config file named `jupyter_config.py`:

c.LabBuildApp.minimize = False
c.LabBuildApp.dev_build = False

If you don't already have a `jupyter_config.py` file, you can create one by
adding a blank file of that name to any of the Jupyter config directories.
The config directories can be listed by running:

jupyter --paths

Explanation:

- `dev-build`: This option controls whether a `dev` or a more streamlined
`production` build is used. This option will default to `False` (i.e., the
`production` build) for most users. However, if you have any labextensions
installed from local files, this option will instead default to `True`.
Explicitly setting `dev-build` to `False` will ensure that the `production`
build is used in all circumstances.

- `minimize`: This option controls whether your JS bundle is minified
during the Webpack build, which helps to improve JupyterLab's overall
performance. However, the minifier plugin used by Webpack is very memory
intensive, so turning it off may help the build finish successfully in
low-memory environments.

An error occured.

その場合は node--max-old-space-size オプションを設定してから JupyterLab をビルドしてみる。

(pyJupyterLab) $ echo 'export NODE_OPTIONS="--max-old-space-size=1024"' >> ~/.bashrc
(pyJupyterLab) $ . ~/.bashrc

システムのスワップメモリーが 1GB しか無い場合は、JupyterLab のビルドでスワップメモリーを使い果たすので、スワップメモリーを増やす必要がある。

Spyder IDE ❓って初めて知りましたけど、有名なのでしょうかねぇ🤔 / Twitter
これもJupyterLab用のPowerShell Kernelの実装ですが、dotnet公式で対応していて以前はプレビューリリースの状態だったようですが、今はこちらが主流になって来ているのかな🤔 .NET Interactive / Twitter
.NET InteractiveはVisual Studio CodeのネイティブNotebook機能として実装されたものですねぇ🤔 MicrosoftもJupyterLabのNotebookを、VS Codeのインタラクティブ実行可能なNotebook機能として取り入れているということですねぇ🥰 / Twitter(Try .NET から名称変更されました)
投資銀行がオープンソース❓Jupyter関係の開発していますねぇ🤔 JPモルガンさんは投資家さんならみな良くご存じのゴールドマン・サックスとかモルガン・スタンレーみたいな世界的な金融グループですねぇ🤔 Project Jupyterは海外ではかなり注目プロジェクトということですね😲 / Twitter
Project Jupyterがすごい巨大化しているような感じがしていたんですよねぇ🤔おそらく世界的なスタンダードということだと思いますけどねぇ🤔 NumFOCUS Foundationさんの支援プロジェクトで...🤔 / Twitter
Python関係の科学技術に関連したオープンソースがいっぱいです🤔 / Twitter
なんですと❓2021/03/04のBlogで.NET Interactiveには、C#、F#、PowerShell、JavaScript、およびHTMLに加えて、T-SQLサポートが付属してるって発表していますねぇ😅💦 / Twitter

JupyterLab Desktop が9月にリリースされましたけど、Electron ベースの JupyterLab で GUI アプリとしてインストール出来て良いですねぇ🥰Linux でのインストールだけ追記しておきましたけど、macosもWindowsもあるので良さげです😊HyperとConflictどうしよう🤔 / Twitter
jupyterlab-desktopではExtension managerが無効化されてる😱😢😢😢😢😢😢😭Extension manager is currently disabled in JupyterLab-app, but it is something that we will definitely want to enable in the future. / Twitter

JupyterLabにTheme入れてビルドしたら、サーバーのコンソールのプロセスごとご臨終😱😅原因はZRAMスワップの3倍盛り設定が消えてました😅3倍設定するとメモリー1GBのしょぼい仮想サーバーでも圧縮メモリーテクノロジーで実質2.8GBまでソフトウェアメモリー増設されます😁
