Projects
Three things worth opening. All three are running right now, and all three show their own working rather than describing it.
The 6502
A transistor-level simulation of the chip that made home computing affordable.
One 6502 was decapped, photographed and traced by hand. This runs those 3,510 transistors, solved to a fixed point twice per clock cycle, and checks itself against the original simulator bit for bit. Plus a link-checked archive of everything the visual6502 team left behind.
Hotbits
Random numbers from radioactive decay, tested continuously.
A Geiger counter, a Raspberry Pi, and a comparison of one gap between decay events with the next. Nothing generates a number. The bias cancels by symmetry rather than by correction, and NIST SP 800-90B runs on every sample as it arrives.
Knock knock
Everything that has tried the doors on this host, across every site it serves.
Three tiers fused into one view: dropped at the edge by the router, trapped at the door by the scanner trap, and served. Almost all of it is automated. Visitors are coarsened to a /24 on purpose; the scanners are not.
What used to be here
An index over 236 generated dossiers, one per repository. That answered which repositories exist, which is a question the work page now answers in one screen and from the same commit data. Keeping both meant maintaining an inventory nobody reads in order to say something already said better elsewhere.
The hand-built instrument pages did not go anywhere: Prime Orchestra, Prime Zoo, Prime Atlas, Critical Collapse, Zeta Forge and Storm Plates are all still where they were.
