Time Machine Utilities
I wrote some shell scripts to automate "fixing" old Time Machine backups, particularly Time Machine backups from previous computers. I've personally experienced a lot of friction with this, and found out that some of the metadata stored in the Backups.backupdb and individual snapshot directories prevent successful use with Time Machine on other computers in some cases. Time Machine itself does not always handle this gracefully. These utilities should help users wrangle older backups to make them work with Time Machine on their current Mac.
In plain words
Time Machine Utilities is a collection of shell scripts that automate the process of fixing old Time Machine backups, especially those from previous computers. It addresses compatibility issues where metadata in backup files prevents Time Machine from working properly on different Macs. The scripts modify backup structure and metadata to make older backups functional with Time Machine on current computers, solving a problem that Time Machine itself does not handle gracefully.

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:…
