Excited to showcase CoCalc at the 2nd MOERFI Demo Day with GWDG at the Rhineland-Palatinate State Parliament!

We're diving into the future of sovereign AI, open infrastructure, and rethinking tools/editors in practice.

We had an excellent time exhibiting at the American Geophysical Union in New Orleans, LA, this week!

We’ve been letting folks know about our new locally installable version of the platform, CoCalc+.

Why does heat diffusion smooth everything out? The ∂²u/∂x² Laplacian term is key! Download our PDE template to visualize Gaussian initial conditions evolving under ∂u/∂t = α∇²u with Dirichlet boundaries.

If you plan to attend the Joint Mathematics Meeting this January, I would highly encourage you to sign up for the congressional visits day (Jan. 8th).

Let our Congress members know about the impacts of cuts to NSF grant funding and changes to visas: https://t.co/3FE5YbNsgY

@zicokolter Hi Zico, I’m just curious if you have ever heard of our platform! I’d love to tell you how it could be helpful for automatic grading, streamlining set up and running your students code.
