Defeating context fatigue with agentic scaffolding – blog
I’ve been thinking about how to improve my agent workflows- and I’ve discovered that there is a productivity speed bump that you hit as you get more fearless with agentic development: You know the agents cannot be trusted to make the right call, so you review …
The Biggest Identity Sandpiles and How to Compute Them
When I wrote Beautiful Abelian Sandpiles I wanted to show off some nice images of large identity sandpiles. But the simple algorithm I used was horrendously slow. Showing a sandpile identity that was larger than 100 by 100 took multiple seconds! That's not goo…
Against Vibes: When is a Generative Model Useful

The Optimization Ladder
Python loses every public benchmark by 21-875x. I took the exact problems people use to dunk on Python and climbed every rung of the optimization ladder -- from CPython version upgrades to Rust. Real numbers, real code, real effort costs.
