Open and run GitHub-hosted (Jupyter) notebooks in Marimo 🤯

• no installation required (full WASM)

• access the GitHub contents from the notebook

• just prepend 'http://marimo.app' to the GitHub URL

Marimo 0.10.10 is out, with real-time collaboration 🎉

This is using the same technology as Jupyter (CRDTs). It's great to see how the two projects can benefit from each other.

As a contributor to both projects I think there can be a future where they share more functionalities.

I just released jpterm 0.2.20, with an update to Textual v1.0 🚀

Textual's ability to maximize the focused widget is awesome from an accessibility point of view. For instance here you can view only the notebook cell that you are currently editing.

I figured that Zulip enforcing topics is a bit like structured concurrency, and now I feel much better :)

Awesome contribution to pycrdt 🚀

With this, pycrdt will support XML shared documents as well as embedded content and formatting attributes in shared text.

I just published the API reference documentation for pycrdt.

It's using @pawamoy awesome mkdocstrings library and it's so beautiful!

If you're not using CRDTs yet, you're missing out. Don't be afraid, they are just basic data structures with superpowers.

Actually @cfbolz you must have a ton of expertise in this field, do you think you will be able to "port" PyPy's optimizations to CPython's JIT, or are the two technologies "incompatible"?

Say I want to implement optimizations in Python's new JIT compiler, where do I start?

Experimenting with an undo/redo feature in jpterm, that will allow to explore the history of a document using a slider.

What do you think? 🤓

The shared files don't live in a central place, but in each browser. This is a distributed architecture, think of it as a peer-to-peer application like BitTorrent.

And since it's based on WebRTC, it will also work in JupyterLite! A signaling server is needed for connecting users.

I just released Jupyter Shared Drive 🚀

This is a new way of collaborating in real-time in JupyterLab. Unlike Jupyter Collaboration, it is separate from your local files. See it as a scratch disk where you temporarily share files with colleagues.

pip install jupyter-shared-drive
