SciPy has been a cornerstone of scientific computing in Python for decades. So where is it going next? Evgeni Burovski lays it all out at EuroSciPy. Check the schedule. 🎟️ buff.ly/p6uzy5q

40x speedup on CUDA. No CUDA C code written. Evgeni Burovski ran the numbers on SciPy's RBFInterpolator across NumPy, PyTorch, JAX, and CuPy backends. The results make a strong case for Array API plus JIT as a real alternative to compiled kernels. labs.quansight.org/blog/array-a...

Empowering open source innovation is core to who we are. We are excited to back the SciPy U.S. community as a Silver Sponsor this year. Can’t wait to follow along with the incredible presentations! 🚀📊 buff.ly/qOunneF #SciPy #OpenSource #DataScience

If you're working with sparse data in Python and wondering what the path forward looks like, Mateusz Sokół will be laying it all out at EuroSciPy. PyData/Sparse, Finch, Array API compatibility, and how to actually migrate your code to benefit from it all. Check the schedule. 🎟️ buff.ly/p6uzy5q

Maintainers and institutions working on the challenges of maintaining critical digital systems together. That's the Maintainathon at UN Open Source Week, now in its second year. Jaime Rodríguez-Guerra is part of the delegation, and it’s so good to see these conversations happening at this level.

Free-threaded Python is reshaping how the ecosystem thinks about extensions and distribution, and the ABI is right at the center of it. Nathan Goldbaum shares hard-won real-world experience at EuroPython. Check the schedule. buff.ly/rSTOhCn

Domain-specific compilers sound intimidating. Mateusz Sokół is going to make them make sense. His talk at EuroPython introduces Finch, a Python-native compiler for structured sparse arrays, and walks through the design decisions, the trade-offs, and the ecosystem role it plays. buff.ly/rSTOhCn

Switching between Polars and SQL requires a fundamental shift in your mental model. Performance gets all the headlines, but semantic differences are what break code. Marco Gorelli laid it all out at PyData London. Watch the full talk:

Excited to see Jaime Rodríguez-Guerra heading to UN Open Source Week as part of the Sovereign Tech Agency's maintainer delegation. It's great to see practitioner voices included in these conversations. Congrats to Jaime and the whole delegation, we can't wait to see the impact of your insights! 🙌

A big milestone for Python-in-the-browser. PEP 783 means Pyodide wheels can now go straight to PyPI. No more bottlenecks for the community. Huge congrats to the community driving this forward! 🎉

AI is absorbing the "visible friction" that open-source communities used to rely on to welcome newcomers. The result? The "Invisible Newcomer." They get the answer. They miss the community. How do we design invitation when the path is gone? Mara Averick shares her analysis here:

We love seeing the Python community thrive. Supporting SciPy U.S. as a Silver Sponsor is our way of helping keep the ecosystem open, vibrant, and accessible to researchers everywhere. ❤️🐍 buff.ly/YuZlpTy #SciPy2026 #Python

3 people. 3 projects. Countless users impacted. Marco, Nathan, and Agriya joined OSS governance in 2025, triaging issues, making technical decisions, and coordinating across the ecosystem. The work that keeps open source sustainable. More in our Annual Report: buff.ly/tPuHdaT #Python #Community

Everyone loves comparing Polars performance benchmarks to engines like DuckDB or PySpark, but what about the underlying semantics? At PyData London, Marco Gorelli steps away from the speed debates to analyze how different relational models completely alter code behavior. buff.ly/D0VctlJ

Managing 20+ people isn't sustainable for one person. 📉 Ralf Gommers explains to Greg Downs why the Co-CEO, with Tania Allard model at Quansight, keeps leadership "hands-on" and community-focused. Full clip: buff.ly/ISadKXy #TechLeadership #Scaling #Management #Innovation #OpenSource
