This seemed like a nice way to enter the exciting world of 5 x 8" index cards.
A pittance of $5.00 at the local thrift shop also included a full set of Universal Paper Goods Stock No. 58-25 card dividers with both alphabetic and numeral printing.

Two big recent self-hosting discoveries. First, the excellent BookOrbit, which has replaced Calibre, Calibre-Web, Komga, and Audiobookshelf in my stack. Second, Quartermaster, which can be found at https://www.qmstack.com, has completely blown me away across iOS, tvOS, and the companion container.

Slowly tweaking a local trained LoRA model to generate stylized images of my cats doing seasonally-appropriate activities. It takes only a few seconds to generate these on the GPU in the closet. Still have some work to do on the poses and image styles. But I'm pretty happy with the progress so far!
