For our cheminformatics competition, you can now win an @Apple Mac Mini M6. You have 1 month left to take a dataset and build a marimo notebook that brings cheminformatics to life. Competition details below.
33 days to win a mac mini.
the challenge: pick a cheminformatics dataset and build a marimo notebook that answers a question you want the answer to.
we're judging based on creativity, not on model accuracy. co-hosted with @wpwalters.bsky.social.
we'll see you in our submissions 👀

What if you could run marimo notebooks for your whole company on your own cloud, behind your own SSO, with no database to run?
We'll be demoing exactly that at tomorrow's community call 👀
Plus...custom web views. That's all we're saying for now.

Python is better than PowerPoint now. You can present marimo notebooks as slides. Widgets stay interactive and you can edit slides live while presenting. No more second window, separate demo, or crossing your fingers.

marimo is reactive, which means that it knows in what order variables are declared.
So what if you had widgets at your disposal that could leverage that?
For launch week, we're releasing some tools that do exactly this.

I finally tried out the @marimo.io marimo-pair skill to do some light data analysis and plotting in conversation with an LLM and it really worked. Tedious plotting layout and syntax fadeed into the background. I used OpenCode + GLM 5.2, @pola.rs and @matplotlib.org Would recommend. #EnergySky

molab has free GPUs and we've been exploring the different ways that you could use them. And there's plenty to do outside of deep learning!
You can use them to tackle TSP problems too. But it helps to rethink your CPU-based algorithms when you go here.

Now that molab has free GPUs we started toying with ideas that aren't 100% practical but might teach us something.
So we asked a question: can we use deep learning to solve (NP)-hard computer science problems?
