Personal blog · nelari.usprogramming
My thought repository is a personal blog at nelari.us about programming. Since 2019, 5 different Hacker News readers have linked it 5 times, most often “Writing a small ray tracer in Rust and Zig”. It is still writing: the last post was on 2026-06-28, and you can follow it by feed.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for its post on blue-noise dithering, which one commenter raises as the major algorithm missing from a list of image dithering methods. Only one comment, and it does not judge the writing.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
This is where I write about the stuff that I've been working on.

What Hacker News says?
The major dithering algorithm that's missing from this list is blue-noise dithering. This is very similar to "ordered dithering"; you can think of ordered dithering as either thresholding the pixel values with a different threshold value on each pixel, following a regular pattern, or as adding a different offset value to each pixel, following a regular pattern, and thresholding the result with a constant threshold.…
