     10 ## Just a QR Code

     12 It does exactly what it says on the tin. 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.

     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.

     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.

     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.
