Stillcolor – Reduce eyestrain on macOS by disabling temporal dithering
Recently got an M3 Max MBP which gave me severe eyestrain after less than an hour of use. Turns out the major cause for that was temporal dithering at the GPU level. I built Stillcolor to disable temporal dithering from user space, which helped massively reduce eyestrain with little to no degradation in image quality.
In plain words
Stillcolor is a macOS application that reduces eyestrain by disabling temporal dithering at the GPU level. The tool addresses a specific issue affecting users of newer Apple Silicon Macs, particularly M3 models, where the dithering process can cause visual discomfort during extended use. By disabling this feature from user space, Stillcolor aims to significantly decrease eyestrain while maintaining image quality. It is designed for macOS users experiencing eye fatigue from their displays.

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:…
