Zero-downtime PostgreSQL migrations for Ruby on Rails
In plain words
Zero-downtime PostgreSQL migrations for Ruby on Rails is a tool for Rails developers who need to update their PostgreSQL databases without interrupting service. It handles schema changes safely while applications continue running, addressing a common challenge in production environments. The tool automates the process of managing database alterations that would normally require downtime, making it useful for teams running live services that cannot afford to go offline during updates.

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:…
