GNU ☛ GNU Guix: Take the Guix User and Contributor Survey
To understand the views of the Guix community we're running a survey that we'd love you to take part in! The Guix User and Contributor Survey is live now, and should take about 10 minutes to fill out. Perfect for doing with a cup of tea and a biscuit!
The Guix project continues to grow and change, with new contributors and users joining our community. We decided to run this survey as it's the best way to gather good quality feedback across the widest cross-section of the community. Of course, there's lots of interesting topics a survey could ask about! We decided to focus on how Guix is used, and how contributors take part in the project.

PostgreSQL ☛ pgvector 0.8.0 Released!
pgvector, an open-source PostgreSQL extension that provides vector similarity search capabilities, has released v0.8.0. This release includes features that improve query performance and usability when using filters (e.g. the
WHEREclause), and performance improvements for searching and building HNSW indexes.This latest version of pgvector has a variety of improvements for filtering. This includes an update to how PostgreSQL estimates when to scan a approximate nearest neighbor (ANN) index like HNSW and IVFFlat, which could lead PostgreSQL to select a B-tree or other index that more efficiently executes the query. If you can achieve the same query performance without using an ANN index, this is usually preferable as it lets you achieve 100% recall, or high relevancy searches.
