Pg_sorted_heap–Physically sorted PostgreSQL with builtin vector search
In plain words
Pg_sorted_heap is a modified version of PostgreSQL that stores data in physically sorted order and includes built-in vector search capabilities. It is designed for developers and database administrators working with PostgreSQL who need efficient vector similarity searches without external extensions. The physically sorted heap approach aims to improve performance for range queries and vector operations compared to standard PostgreSQL installations.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
