Production tools that turn fragile, repetitive work into
explicit systems with durable records and testable outcomes.
Workflows/Data/Release
Reading it: jobs run left to right through four gates.
Some fail. Hover and the retry path opens, so failures are caught instead of
lost — and the ledger keeps every completed run. Move down to push the load.
02Forgetting curve
Learning systems
Educational products built around the learner, the real
task, and the evidence that learning actually transferred.
Curriculum/Interfaces/Evidence
Reading it: every square is one thing a learner knows,
fading as they forget it. Sweep to review. Anything you catch late comes back
stronger and fades slower next time, which is the whole trick.
03Edge routing
Edge applications
Fast, contained web applications with careful account
boundaries, explicit failure behavior, and observable deployments.
Cloudflare/Workers/Security
Reading it: requests go to the nearest server. If it
already has the answer the trip is short; if not it goes all the way home, which
you can see take longer. Servers fail on their own and the map redraws.
04Double pendulum
Computational modeling
Simulations and numerical models that make behavior
observable, so physical and emergent systems can be run, watched, and tested.
Simulation/Physics/Visualization
Reading it: two identical pendulums, released a
ten-thousandth of a degree apart. Watch how long they agree, then how completely
they don't. Hover slows time. Click to drop them again.
Every card names its own mechanism, top right, and keeps a live readout. All four run
on their own and use hover to steer rather than to switch on. The toggle repaints page
and sims from the same CSS variables.

Every engagement runs as a sequence, not a handoff.
