How things work
Interactive models and sourced explainers: open one and poke at it.
AI
4 pages
A tiny GPT you can run, a team of models building a feature, how to design the graph they work in, and the team that will run it all.
Physics
5 pages
Atoms, galaxies and orbits, all running on your GPU.
Quantum computing
3 of 12 open
Drag a qubit, cancel a path, search a list: quantum computing from the amplitudes up.
Biology
1 page
Inside the brain: lobes in neon, signals racing along the tracts.
Simulations
4 pages
A few rules on the GPU, and the patterns that grow out of them.
EV charging
3 pages
How a car and a charger talk, signal by signal.
Automobiles
SDV 6 · EV 3 · V2X 5
The software-defined vehicle: how a modern car is wired, layered and regulated.
The synth on my desk
3 pages
Every knob mapped, the shapes that move a sound, and how I use it.
Chords, a trip away from home
4 pages
Hear a chord progression leave home and come back, and type your own.
How developers learn robotics
4 of 10 open
Two on-ramps, one shared core and a real humanoid to finish: drag a frame tree, a two-link arm and a PID.
Zero trust, one request at a time
4 of 10 open
Where a request comes from earns it nothing: be the policy engine, plant an attacker, relay a login.
Security in the age of AI
4 of 7 open
Against attackers that move in seconds, I argue only constant monitoring keeps up: the hours nobody is watching, with sources.
Blockchain, recomputed
3 of 11 open
Hash a real Bitcoin header and get the block’s own ID back; read an Ethereum explorer page knowing what is on the chain.
