I do in-house backups for my data, but the system that eats the data now is an all-in-one Intel Atom PC with a dying fan, and I don’t really trust it. Luckily we’re in the future, so fanless ARM-based...

Yet more abstract images
I had some new ideas on generating pictures based on Z-order curves. For speed this time, I wrote some truly horrific but decently fast C code to render stuff. I also re-did some of my earlier Hibert...

A simple thing I’m proud of

A 3D printed knife block
I recently got a few new knives, including a really long bread knife, and my old trash knife block didn’t fit them. I designed a new one. Might be my longest print yet: 55 hours. Printed in this...
