Your research, your challenges, your solutions. Compute! Paris 2026 (Nov 25-26) wants to hear from you. The Call for Proposals is open. Don’t just attend; help shape the conversation. Whether you’re in academia, industry, or public institutions, your voice matters. pretalx.com/compute-pari...

This was quite some work and proud to have it finally out!

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. github.com/apache/arrow...

Everybody is talking about secure Python sandboxes for LLM code execution, but what about using the browser sandbox? Quick demo using JupyterLite and the Pyodide kernel 💡

A viewer for Parquet, SQLite, and Avro files in JupyterLab. Check out our new JupyterLab extension: Arbalister. 🏹 Built upon Apache Datafusion, @jupyter.org , and @arrow.apache.org , it lazily fetches rows so that you can view files larger than memory! blog.jupyter.org/instantly-vi...

We are thrilled to introduce notebook.link, a platform that lets you create, share, and run Jupyter notebooks instantly in your browser. Powered by JupyterLite and WebAssembly, it supports Python, R, C++, and a full in-browser terminal experience. 📖 Read the full story: medium.com/@QuantStack/...

SIMD coding is hard: platforms, inconsistencies, lane constraints... but xsimd abstracts a lot away. With my first contributions, I improved byte shuffling, now available in the latest 14.0 release. #C++ #SIMD #xsimd #openSource

Register for the Apache Arrow Summit Paris 25 (October 2nd) at: www.meetup.com/pydata-paris... The event is hosted by @pydataparis.bsky.social We are looking forward to seeing you there and talking about all things Arrow.

I'll be attending the event, looking forward to meet Python folks!
