Anyone have an e-reader they like? Amazon will stop supporting library books on my 16 year old Kindle, and I'd like a replacement for an upcoming trip. I hate that tech is disposable, but 16 years was a pretty good run. Main constraint is that I'll pay extra to avoid ad-supported awfulness.

Retiring a climbing rope and didn’t want to throw it out. Didn’t like the first attempt so redid with a more interesting pattern. The initial pattern was the hard part, feeding rope into it (still needs adjustment) is the tedious part.

Initial mat pattern. An orange climbing rope is laid out on yoga mats. It forms a loose pattern. Strips of paper label crossings.The pattern now contains three passes of the rope. It is still loose.The pattern now contains four passes. A rabbit foreman inspects the work.The nearly-finished pattern sits on a wood floor. It contains five passes. A strand extends from the corner, indicating its creator still feels non-committal about calling it finished.

Significantly more work than I expected, tbh. Tempted to loosen up the pattern and give it some breathing room—but it's just so much work to feed all the rope through to adjust the pattern.

The beginning stage of an ocean plait mat made out of used orange climbing rope is laid out on a yoga mat. A rabbit sniffs cautiously at it.A small white dog now sits at the edge of the yoga mat, looking with uncertainty down and to the right. The plait mat now has about eight or nine passes completed, with quite a bit of loose rope to be pulled through yet.The (nearly) finished ocean plait mat sits on the yoga mat. It is pulled tight, with no gaps in the pattern. Two loose strands dangle from it, not yet cut off.

Nice, figured out how to fetch some Arctic DEM data, fill in the gaps with Copernicus GLO-30, run it through rio-tiler, and connect a WebGPU viewer with some basic level of detail refinement.

A low-angle view of Denali, looking up the northeast fork of the Kahiltna Glacier. The view is computer generated with basic hillshading and a flat blue sky.

I was fine with it not arriving until after Christmas. I was worried 111 pieces wouldn’t be enough. I was worried it be sorta trivial with no wrong answers. @nervo.us your Spectre tile puzzle has exceeded all expectations! My mother in law is thoroughly nerd-sniped.

A wood-cut aperiodic monotile puzzle sits on a wood table next to a cup of tea and a hand holding a single Spectre tile. Sections are assembled, but a coherent assembly is lacking.

Can you believe that back in the day the recommended solution was not just to shut it down and turn it back on again, but to actually drop the entire thing six inches onto a hard surface in the hope that loose senators would reseat themselves?

Expanded it to work across an array of satellite tiles and added soft shadows. Softening shadows around the azimuth is easy because you just average samples (here, 16), and along the altitude is even easier because the horizon algorithm gives enough information to simply do a smooth fade.
