DeltaSnap
Version control your Mac: find, compare, and restore files.
What it does
DeltaSnap turns native APFS snapshots into searchable file history, visual diffs, automatic checkpoints, monitoring, and selective recovery.
A safety layer for AI-assisted work on Mac. DeltaSnap turns native APFS snapshots into searchable file history, visual diffs, automatic checkpoints, monitoring, and selective recovery.
Built for a single-user Mac, DeltaSnap turns native APFS snapshots into Version Control for every file and folder. Delete the wrong thing, let an agent run wild, or break a project at 2am, and you can find the earlier version and put it back in seconds. APFS snapshots live on the source volume and cannot protect against loss, erasure, or failure of that disk. Maintain independent backups and verify the integrity and recoverability of your data. Before a risky update, AI-agent run, bulk edit, or project milestone, take a native APFS checkpoint. If something goes wrong, diff what changed and restore the files you need. Browse or search current and deleted files, then open their captured…from scaleninja.com

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:…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
