Pixi now fully supports archspec, so you can create CPU-optimized environments and let Pixi handle the installation logic. Read more about it in the blogpost we updated: prefix.dev/blog/buildi...

Any Rust, C++ or Python project on GitHub can become a global tool on your machine. No recipe, no manifest in the repo. Just name the backend.

Pretty amazing the things you can do with textualize!

I built a thing... Dinkus Markdown Studio for Mac. Visually author Markdown with a native app. Images, tables, code blocks, and more, are displayed in the editor. Try typewriter mode and paragraph or sentence focus for a distraction-free writing experience. dinkus.textualize.io

JupyterLite 0.8 is out: shareable REPL links, a refreshed loading screen, file system fixes, an in-browser terminal with real WebAssembly tools (git, vim, grep), more kernels via jupyterlite-xeus, and Python 3.14 on Pyodide. Try it with no install: jupyter.org/try-jupyter

CEP 48, which brings conditionals and extras to your @conda.org dependencies, is now accepted! This means you will soon be able to type things like `typing-extensions[when='python<=3.10']`  and `scipy[extras=test]` 🚀 github.com/conda/ceps/b...

Conda packages have extras now. Optional dependency groups you declare and then consume, via v3 repodata. Plus when conditions and variant flags.

Polars and SQL operate on fundamentally different mental models. Marco Gorelli explores the architectural nuances that shape both paradigms. Understanding these mechanics is key to writing clean code that generalizes seamlessly across query engines. Read Marco’s full analysis: buff.ly/J31DcJK

[system-requirements] is deprecated. Platforms now carry the requirements themselves. CUDA and glibc constraints inline, and you can name a target what you actually call it: jetson-nano.

OSS collaboration is great to see. I know Nathan has been a core part of moving the scientific Python ecosystem forward! :heart:

Ten years ago, I founded QuantStack on a conviction: that we could build a sustainable business by supporting world-class open-source software to advance science. We had no outside funding, no guarantees, just trust in open collaboration. Read the full story: quantstack.net/blogs/Decade...

I have ~forever been on about the dangers of technical debt due to my lived experience of failed codebases. I think understanding tech-debt and it's tradeoffs has never been more important than it is now. Once in a codebase, the cost of technical debt increases exponentially.

Numba now runs entirely in the browser through #JupyterLite and emscripten-forge 🤘 Read Anutosh's post for more details on how we brought Numba's JIT compiler to #WebAssembly, enabling a broader ecosystem including PyTensor, PyMC, Interpolation․py, and Dolo․py. notebook.link/blog/numba-i...

The ability to specify all the non-python dependencies your script needs is a game changer!

pixi 0.76 can now run standalone python scripts in isolated, on-demand environments. dependencies live inline via PEP 723, like uv supports, but pixi can layer on conda and system dependencies too. fun to build this with @prefix.dev folks. coming to a @marimo.io notebook near you SOON.

44 seconds down to 1.5 seconds. That is the difference free-threaded Python made once the real bottlenecks got fixed. Read how each one was found and fixed. buff.ly/9Z6f5ux

Most compression libraries ask you to move in. We think that's backwards. Blosc2 4.9.1: DuckDB, Polars and pandas 3 read a CTable directly via Arrow's PyCapsule protocol — no conversion step. Cooperation, not completeness. blosc.org/posts/not-an... Compress Better, Compute Bigger 🚀 #DataScience

The rattler-build playground got a bit fancier! Now also generates recipes for PyPI, CRAN, and CPAN upstream sources. Try it out under playground.rattler.build

Fascinating to see how AI is used in mathematics by true experts! 🤯

`anycorn` is my go-to ASGI server. I have more trust in the correctness of applications built on top of `anyio` due to the guarantees of structured concurrency.
