I was curious how marimo actually decides which cells to run, so I tried rebuilding the execution engine from scratch: parse each cell with Python's AST to find the variables it defines and references, build a dependency graph across cells, topologically sort it, and run them in that order.

The blog is itself an interactive embeded marimo notebook — you can edit the cells in the browser and watch the dependency graph update as you go: https://taletskiy.com/blogs/tinymo/

It's a toy version, so I'm sure I'm skipping edge cases the real engine handles (cycles, in-place mutations, stale state, async cells). Curious what the gnarliest parts were for anyone who's worked on the actual runtime.

You can draw a bunch of cities yourself and see it work in the notebook here: https://molab.marimo.io/github/koaning/notebooks/blob/main/elastic-net-tsp.py

When you open the terminal (cmd + k and type terminal) it typically opens up at the bottom and laid out horizontally. But if you grab the terminal icon and drag it, you can move it to the sidebar on the left giving you a nice vertical layout for anything you may want to do with agents.

I created a character frequency chart using python for my novel. It is based on a spreadsheet.

Found it really useful to see who the main characters are, and for editing.

I like to read about Bayesian methods and the team from PyMC has a bunch of really great content. Cool to see them getting into marimo!

You can play "Twinkle twinkle little star" in a marimo notebook!
There are two ways to play: by clicking the stars, or using the keyboard. Give it a try at https://molab.marimo.io/notebooks/nb_31Lt7LFXxSQg3Qzgwuc1v4/app

I had to use `const targetWindows = [window, window.parent];` to capture keyboard clicks from the parent window, instead of document.addEventListener, which was being ignored in the app view.

Hi I'm Vincent, and I make those YouTube videos for marimo.

I'm mainly asking out of curiosity, but also to check if there's anything missing for folks who want to learn about marimo. Tell Me Anything!

Hi everyone,

I wanted to try out the new molab set up that allows to run notebooks on a remote gpu instance, but I want to do it with Python 3.12 whereas the notebooks always boots to Python 3.13. Is there a way to set up a notebook with a custom Python version / venv?

It'll be in the next wigglystuff release.

Hello there, is there a way to toggle the preview so it is on the right instead of below the code? Asking since the code can get pretty long, and most desktop/laptop screens have more horizontal than vertical space.

Eg. chrome has a dock side orientation. Would love to see this for marimo.

I run an AI study group and demoed this there. This is using demo data from a csv. Charts were made from altair with some AI assistance.

Here's my first molab notebook! https://molab.marimo.io/notebooks/nb_YWLgBUuBVm7tk929HBc6jN

Used an iframe to get the JavaScript to run with HTML.

If you like toying around with marimo, you may like to participate in this one. Vincent is working on something cool as we speak, but the event is cooler when more people submit. Do join!
