I absolutely love that this can be hosted on Github Pages. Am I correct in understanding that these notebooks will run independently, and will not need to proxy through marimo.app (in case the app goes down), or is that what the CORS thing is about in note 4, and it will still need to go through this domain?
Yea, this can be hosted on GitHub pages without any vendor infra (no marimo.app)
These are two separate features:
1) marimo.app + github.com/path/to/nb.ipynb does run on marimo.app infra. this is what the Show HN was about
2) separately, you can use the marimo CLI to export assets to deploy to GitHub page: `marimo export html-wasm notebook.py -o output_dir --mode run` which can then can be uploaded to GH pages. This does not find all the data in your repo, so you would need to stick any data you was to access in a /public folder for your site. More docs here: https://docs.marimo.io/guides/exporting/?h=marimo+export+htm...
Nice ! Is it possible to connect to an in browser DB like WASM DuckDB https://duckdb.org/docs/api/wasm/overview.html or https://github.com/babycommando/entity-db ?
That would be most useful imho !
duckdb works — just import duckdb. We also have built-in SQL cells, powered by duckdb, which should also work.
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.
I feel like pytomls and shared source are becoming standard, but yes-
notebooks vs research code are sometimes very separate, very difficult to directly reproduce. A big difficultly with "working out of the box, shared in browser" is that weights, training, inference, simulations- are all still very compute intensive.
BUT the nice thing about a stateless notebook, is that you can precompute values- and cache them. I've been really excited about expanding marimo's caching system, and would love to get to a point whether sharing a notebook means being able to run the research yourself without some big setup dance.
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.
Blazor is another example
This is really cool -- going to show it off to my team. I love the fact that you opened it up so that it will work with Jupyter notebooks as well.
The future is awesome. Thanks for building this!

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

> 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.
Thanks for sharing these resources
> [ FUSE to GitHub FS ]
> Notebooks created from GitHub links have the entire contents of the repository mounted into the notebook's filesystem. This lets you work with files using regular Python file I/O!
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-...

"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

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
There is $300k in bounties if you create under 1MB WebAssembly CPython distribution
https://www.reddit.com/r/Python/comments/1huxrs6/python_runn...
50k for the 1mb challenge. The rest is to build out the tooling. It looks like they want to run existing ML python libs from within the NEAR blockchain environment.
Wondering why they don't separate concerns here.
now that's a weissman score
Oh that's great
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)
