The Missing Bit is a personal blog at kuon.ch about programming. Since 2020, 8 different Hacker News readers have linked it 20 times, most often “HSLuv, a developer friendly perceptual color space”. It is still writing: the last post was on 2026-09-10, 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 post for its base24 number encoding and its .NET implementation. The one comment cites it as a related implementation alongside other base24 versions, without judging 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.

What Hacker News says?
Providers should really stop using spam folder and refuse email at the session lvl, that alone would fix the false positive issue. I had a rant [1] about it a while ago. [1]: https://www.kuon.ch/post/2024-09-16-email-rant/

HN discussionI came up with base24[1] for this. There are some letter that can be ambiguous but I kept them to make it case insensitive. [1]: https://www.kuon.ch/post/2020-02-27-base24/

HN discussionNot to brag, but I wrote an article[1] on HSLuv which is very well suited for this kind of "contrast ensuring color selection". Some new color spaces with the same purpose exist now, maybe I should update it. [1]: https://www.kuon.ch/post/2020-03-08-hsluv/
