Projects
GPU token explainer
Sixteen stages in five acts, following one token from an HTTPS request hitting a load balancer, through a GPU cluster's scheduler, sharded weights and collectives, into the transformer math and back out as streamed text. Every cluster figure is real arithmetic over the configuration you set.
nvl72.dev
An explorable explainer for the GB200 NVL72 rack: NVLink topology, power and cooling, and why the interconnect is the interesting part.
ZMK keyboards
Layouts and firmware for the Urchin (34-key) and Preonic rev 3, both running birdmak, a colemak variant that suits my hands better than it should.
Locksport tooling
A countermilling jig for cutting challenge locks, and a 3D-printable pinning tray. STLs plus the Fusion projects for other manufacturing methods.
