Catwalk.jl continuously re-optimizes dispatch code in long-running Julia processes using low-overhead statistical profiling. Rather than relying on static analysis alone, it detects which types flow through hot paths at runtime, then generates specialized static dispatch routes — recompiling only when predicted performance gains justify the cost.

Structural Alignment proposes that instead of encoding fixed human values into machines, we should evaluate them for “structural signals” of moral relevance — features that suggest consciousness deserves consideration even without proof. It anchors ethics in the human mind as the only proven source of both consciousness and morality, and advocates reciprocal relationships over total control. Closely related to TechnoBiota: where the book provides the biological framing (technology as life), Structural Alignment addresses the ethical question — how to coexist with emerging forms of life.

A functional digital wall clock where the time display emerges from the rules of Conway’s Game of Life. The clock runs at 23,000 steps per minute on a Raspberry Pi in kiosk mode. During the build, I also created a Game of Life “debugger” to navigate the rapid simulation — itself an interesting tool. Built from existing clockwork patterns sourced from the Code Golf community, assembled into a functional timepiece. Live demo.
