wow a python interpreter is "only" 100MB not sure if that's what's happening here

It is much smaller than that, Pyodide is only 2.8mb and the Python stdlib is 2.3mb when zipped

Is that too small or too large in your estimation?

Wrt web pages supposedly being a couple megabytes it's a big number but at the same time it seems expected with these kind of applications (usually when I see WASM it's a 3D video game)

Super cool to see a real use-case of WASM outside of just game dev and nerding out.

We also have Flash, Java Applets, ActiveX and Silverlight back, running on top of WebAssembly.

Could BusyBox sh compiled to WASM (maybe on emscripten-forge) work with files on this same filesystem?

"Opening a GitHub remote with vscode.dev requires GitHub login? #237371" ... but it works with Marimo and JupyterLite: https://github.com/microsoft/vscode/issues/237371

Does Marimo support local file system access?

jupyterlab-filesystem-access only works with Chrome?: https://github.com/jupyterlab-contrib/jupyterlab-filesystem-...

vscode-marimo: https://github.com/marimo-team/vscode-marimo

"Normalize and make Content frontends and backends extensible #315" https://github.com/jupyterlite/jupyterlite/issues/315

"ENH: Pluggable Cloud Storage provider API; git, jupyter/rtc" https://github.com/jupyterlite/jupyterlite/issues/464

Jupyterlite has read only access to GitHub repos without login, but vscode.dev does not.

Anyways, nbreproduce wraps repo2docker and there's also a repo2jupyterlite.

nbreproduce builds a container to run an .ipynb with: https://github.com/econ-ark/nbreproduce

container2wasm wraps vscode-container-wasm: https://github.com/ktock/vscode-container-wasm

> CORS and GitHub

The Godot docs mention coi-serviceworker; https://github.com/orgs/community/discussions/13309 :

gzuidhof/coi-serviceworker: https://github.com/gzuidhof/coi-serviceworker :

> Cross-origin isolation (COOP and COEP) through a service worker for situations in which you can't control the headers (e.g. GH pages)

CF Pages' free unlimited bandwidth and gitops-style deploy might solve for apps that require more than the 100GB software cap of free bandwidth GH has for open source projects.

There is $300k in bounties if you create under 1MB WebAssembly CPython distribution

I love seeing projects like this. When Pyiodide came out I was excited but it was a bit difficult to use, this looks and feels fantastic.

I really like Observable as well, but I've found it difficult to find robust and broad numerical libraries in javascript like what Python has.

I would love for this type of tool to redefine how we do science. It would be amazing if many scientific papers included both their data and the code in an interactive environment with zero installs and configuration. Plus when discussing a paper you could "fork" it and explore different analysis options live which for many fields would be totally feasible to do in the browser.
