Put some final touches to Toad's permission request screen.
When the agent has an update, it pops this screen up. You can review the diffs in unified or split view, then decide if you want to accept or reject the changes.

Microverse is a version of JupyterLab that runs entirely in the browser. Unlike JupyterLite, it runs a server in the browser.

Looking at Toad's console, I can see some similarities with a Jupyter notebook, with AI superpowers.
I started github.com/davidbrochar... a while ago, but I'm wondering if Toad could be "Jupyter-compatible".

Sneak preview of what's coming to Microverse: real-time collaboration 🚀
This is not a re-implementation of JupyterLab's RTC so that it runs in the browser, it is the same Jupyter Collaboration package.
That's exactly what I expect Microverse to bring to the table: more compatibility with JupyterLab.

JupyterGIS-tiler can do a lot of processing in the backend. For instance you can clip a raster layer with a vector polygon, and have sub-pixel rendering.
Here is an example of DEM clipping with the Amazon river watershed:

If you think you should use asyncio because it's the native async framework in Python, you might want to read this (TLDR: use AnyIO instead):

Microverse is deployed on GitHub pages here:
davidbrochart.github.io/microverse/
Note that it doesn't work in Firefox and that it's quite slow to start up (see dev network).
It's still very early stage, but it's improving. One interesting feature is how kernels can be shared between browser windows.

Microverse is a new in-browser version of JupyterLab. Don't we already have JupyterLite, you might ask?
While there is no web server in JupyterLite, there is one in microverse, and it is Jupyverse.
I think this will open up new possibilities.

The day before treason day (jk) is a terrible time to announce anything, so consider this a teaser.
I've spend the last two afternoons hacking on an experimental terminal UI for a AI coding agent called Toad 🐸

My talk at PyData Paris on "Parallel processing using CRDTs" has been accepted and I want to illustrate it with the image bellow.
The small ships are all the peers that are concurrently mutating the global state (the big ship). They can all diverge temporarily but they tend to converge eventually.

I'm working on a new in-browser JupyterLab. The difference with JupyterLite is that there is a server running in the browser 🚀
It's actually Jupyverse, a FastAPI-based Jupyter server.
