NumFOCUS is proud to be a community supporter of the Feature Store Summit 2026! 🎉
On Oct. 6, Hopsworks is bringing back this free online conference for the 6th time, with 15+ technical talks from teams at Spotify, Adyen, Uber, Airbnb, Delivery Hero, Zomato, and more. This year's theme is real-time context for agents: fresh features, low-latency serving, and the memory and retrieval systems that keep agents reliable in production.
If you build data and ML systems, this is a great chance to learn from practitioners and connect with the community. Registration is free: hubs.la/Q04yshN40

Our third SciPy keynote speaker works at petabyte scale.
Dr. Joseph H. Kennedy is a Staff Scientist at the Alaska Satellite Facility and Geophysical Institute at the University of Alaska Fairbanks. A computational glaciologist by training, he now leads global-scale remote sensing and Earth-observing data processing campaigns — including the ITS_LIVE global glacier velocity project and HyP3, ASF's on-demand processing system.
His specialty is bridging scientists and software engineers, building cloud and HPC platforms that turn raw satellite data into analysis-ready insights for the scientific community.

Our second keynote speaker at SciPy 2026 approaches science and technology from a fascinating angle.
Amber Case is a design advocate, researcher, and author of Calm Technology — and founder of the Calm Tech Institute. She's a Fellow at MIT's Center for Civic Media and Harvard's Berkman Klein Center for Internet & Society, and received the Bell Labs Claude Shannon Innovation Award.
Her work explores how humans interact with technology, and how design can reduce cognitive load rather than create it — a question that feels increasingly urgent as our tools grow more powerful.
