i’m @pycon.us with the rest of the @marimo.io team. come say hi!

got to talk through more of the engineering behind marimo-pair, writing skills, and interactive visualization. thanks for having me on! www.youtube.com/watch?v=K791...

Really enjoyed coming on Real Python and chatting about marimo-pair!

need to rewire my brain

on the orange website www.youtube.com/watch?v=6uaq...

building marimo pair has been a new kind of engineering (for me). a lot changes when the consumer of your api is a model rather than another program. we’ve shipped “breaking” changes without upgrading or migrating the skill. the models just figure it out. hope you like it :)

the latest release of the @marimo.io @vscode.dev extension adds LSP diagnostics for marimo rules multiple variable definitions and dependency cycles are flagged as you type:

Introducing quiver: a (type-safe) place to keep your arrows @arrow.apache.org quiver is a small schema library for Arrow, built on @idl.uw.edu flechette - Define table schemas in TS - Validate schemas at IPC parse time - Get back fully typed Tables (no type-casting) github.com/manzt/quiver

spent some time last weekend getting higlass to play nicely inside @marimo.io molab.marimo.io/notebooks/nb...

some of the first things new users notice and love in @marimo.io are our opinionated formatters (e.g., our table for dataframes) for v0.20.0 I worked on one aimed at AI engineers: a rich formatter for @pytorch.org `nn.Module`

my new bug, minnow

breaking news: dads are learning @marimo.io

thanks for having me!

byoe (bring your own editor) for @marimo.io is here. built from scratch with LSP + uv marimo.io/blog/vscode

👀 preview: @marimo.io notebooks are Python first inside @vscode.dev. we're also integrating managed sandboxed environments for PEP 723 notebooks, powered by uv ofc. forget venvs

look ma, @marimo.io 🤝 cursor (w/ the upcoming @vscode.dev extension). things are starting to come together...

a new life for my 2019 macbook pro

i’m used to hearing from strangers when my open-source "fails" them… this made my day

still lots to do... but we're cooking on a native @vscode.dev extension for @marimo.io notebooks

if interested in creating anywidgets of your own, our tutorial was finally shared to youtube: www.youtube.com/watch?v=frEo...

learning a new api? `mo.inspect()` your objects in @marimo.io. no more dir() / help()-ing around `<object at 0x...>`...

ok actually this time

Observable-like cell minimap coming soon to a @marimo.io notebook near you 🫡

happy to finally share what we've been cooking 🍳

I’m also excited to be presenting Oxbow as part of my talk on composability at the #SciPy2025 Conference on Wednesday! Hope to see some of you there. cfp.scipy.org/scipy2025/ta...

@marimo.io now has a tree-based UI for uv environments add/remove/upgrade deps the uv way — no more flat pip-style lists or accidentally pip-ing your env

spending some time on our uv integration in @marimo.io – starting with things like this selector for package “extras” what’s frustrated you about using packages in notebooks?

preparing for some potentially unhinged things...

have a nice budget to upgrade my at home setup. what’s one thing that ~actually~ made a difference in your space?

sorting row order of a an altair plot in @marimo.io ...

it's actually a pretty fun ui challenge! here's a `Sortable` list alternative... gist.github.com/manzt/1ca8f8...

hard not to approach such questions through the lens of “there is only one test” @allendowney.bsky.social

is the nba lottery rigged? a friend asked, and i ran the numbers in @marimo.io: trevorma.nz/blog/is-the-...

thanks to a community member, we now have an official @vuejs.org bridge for @anywidget.dev! github.com/manzt/anywid...

@frank.computer walking #PyConUS through the humbling experience of navigating charts with a screen reader. excellent talk!

at pycon! wrote a bit about exceptions and borrowing good ideas from python for typescript on the plane today... trevorma.nz/blog/catch-e...

there are 1,100 words in this article and zero of them are "bus"

Oh, hey, we're on there! #OpenSource

ok fine i’ll learn jj

life update! i'm excited to share i'm joining @marimo.io trevorma.nz/blog/im-join...

could really use something like this in anywidget.dev

marimo was just featured on @nature.com! Read the article to learn how issues of reproducibility and reusability are causing scientists at Stanford and elsewhere to choose marimo as their Python notebook of choice.

usually i’m all for “use whatever works for you,” but it’s tough seeing someone trip over Python stuff knowing…

now on the Jupyter blog! check it out

concretely, a JS dev can use any Python CLI without having Python (or uv) installed: # jupyter npx @manzt/uv tool run --from=jupyterlab jupyter-lab # marmio npx @manzt/uv tool run marimo
