🎉 JupyterLite is now part of Project Jupyter!
Run Jupyter notebooks directly in your browser: no server, no setup.
Many thanks to the JupyterLite contributors and supporters like QuantStack, Bloomberg and the Gates Foundation.

We are thrilled to announce that JupyterLite is now an official part of Project Jupyter. This milestone marks a significant step forward…
At @quantstack.bsky.social we designed novel bit-unpacking SIMD optimizations for @arrow.apache.org and #ApacheParquet, and implemented them entirely using C++ metaprogramming instead of Python-based code generation.
We'll publish a deep dive blog post soon.

📣 We are delighted to release mamba 2.6.0. 📣
This minor version includes the support for sharded repodata, significantly improving the UX of the project.

We just published a blog post going into some detail on what makes patching source code hard: prefix.dev/blog/flickz... – it's not just the relatively unstructured diff formats. Source code also lives and breathes, and moves!
Submit your talk proposal for Compute! Paris 2026. The Call for Proposals is open from April 15th to May 24th, 2026.

The notebook.link team is building "serverless scientific computing" on top of the modern Conda ecosystem & the prefix.dev package server. Read the guest blog on how they shipped interactive WASM for Python, R, C++, Fortran and more: prefix.dev/blog/server...

How well do you really know the tools you use every day? At Compute! Paris 2026 (Nov 25-26), go beyond the API and documentation and learn directly from the builders of Jupyter, Scikit-learn, and more. Knowledge is power, get yours!

New in Git, ✨ git history ✨ (I don't mean the Git history 🫠 )
😰 Oh shit, that old commit's message had a typo!
😌 git history reword <commit-id>
😰 Oh shit, that old commit is too big!
😌 git history split <commit-id> (to split it into two commits)

Rationale for this change
The current bit-unpacking algorithm (which is implemented as a C++ code generator script in Python) does not fully leverage SIMD operations: all loads and some bitshifts u...
The open source Git project just released Git 2.54. Here is GitHub’s look at some of the most interesting features and changes introduced since last time.
TL;DR - we have extended the Rust crate diffy to be able to patch real-world source code with real-world patches, which is surprisingly hard! In the process we renamed it to flickzeug.
Notebook.link combines WebAssembly and the conda ecosystem to deliver scalable, serverless computing environments that run entirely in the browser. No backend. No scaling headaches. Just instant, collaborative scientific computing for everyone.
