Do Fixes Have a Shape?
An explorable map of Redis repairs asks whether changed call chains and syntax trees collapse into recurring geometric families when names are removed.
What Vectors Are Good At
87% of real Enron mail is one-shot linearly separable. Widening the embedding 32x moved that by 0.06. The separation theorems are indexed by a dimension you cannot buy.
The Laplacian Is the Shape of Disagreement
The operator behind image edges, heat flow, graph Fourier modes, and the question I want to ask next: when should context travel through a network?
Billion FizzBuzz
484 seconds down to ~1.2, in Rust. Along the way: a benchmark harness that was lying to me, an optimization that made things worse on purpose, and a wall neither more threads nor more code could move.
Hailstones on a Mac Air
3n+1 through GMP, hand-rolled NEON, and a Metal GPU kernel on a MacBook Air. Two results ran opposite to what I predicted.
