This is an in-browser QR code 13 generator that doesn’t add any tracking info to your links, or track _you_ when 14 you use it. 15 16 [Just a QR Code](https://justaqrcode.com/) 17 18 ## “The most radical thing you can do is care” 19 20 A lot of folks in my network are sharing Dan Sinker’s reaction to the news 21 about the sloppy LLM-generated “summer reading supplement” that was published 22 in a couple newspapers, and I’ll join them. 23 24 For inscrutable and personal reasons, I think it makes a good companion to [28 25 slightly rude notes on 26 writing](https://www.experimental-history.com/p/28-slightly-rude-notes-on-writing) 27 from Adam Mastroianni. 28 29 [Dan Sinker --- The Who Cares Era](https://dansinker.com/posts/2025-05-23-who-cares/) 30 31 ## The OKLCH color space 32 33 I love color, even though I don’t see it the right way: a not-uncommon color 34 deficiency[^colorblind] means that I muddle certain combinations, e.g. browns 35 and greens, or blues and purples. Nevertheless, I’ve long been obsessed with 36 Joseph Albers’s _Interaction of Color_, and give more thought to the color 37 schemes I use for my data visualizations and other digital artifacts than is 38 sometimes appropriate. I was always frustrated that CIELAB didn’t see broader 39 adoption by designers, even though the advantages of a (somewhat) “perceptually 40 uniform” color space seemed self-evident to me. 41 42 So I was stoked when I stumbled upon the OKLCH color space---which [Björn 43 Ottosson developed to address some of CIELAB’s 44 shortcomings](https://bottosson.github.io/posts/oklab/)---and learned that it 45 has become widely adopted in web browsers and graphics programs in the past 46 couple years[^old]. The color picker below is a great place to start exploring. 47 My only concern is related to colorblindness: using this color space, it’s _too 48 easy_ to make colors that differ only in hue, which is generally a bad idea for 49 displays. 50 51 [Evil Martians’ OKLCH Color Picker & Converter](https://oklch.com/) 52 53 [^colorblind]: I’ll casually describe myself as “colorblind” but I actually 54 have “deuteranomaly”; I have three different kinds of cones like folks with 55 normal color vision, but my M-cone is a little _off_. 56 57 [^old]: I missed this because Debian 12 is stuck on Inkscape 1.2.2, and this 58 feature was added when 1.3 was released nearly two years ago. This is why 59 people make fun of Debian stable users.
