The Swiss timetable is a constraint solver in a trench coat
Why scheduling Swiss trains is one of the hardest optimisation problems hiding in plain sight — and how the same PESP math pre-flights your construction site.
One Endpoint, Every Model: Routing Your AI Coding Agents Through a Local Proxy
Weave's open-source router picks a model per request using an on-box embedder, not a prompt. Setup, a routing histogram hack, and the trade-offs.
Austin Bought 21 Trams. The Real Order Was a Dependency Graph.
Stadler wins Austin's 21-vehicle CITYLINK contract. Why the fleet count is a headway constraint, the catenary is the permanent layer, and how to run the sag maths.
The Parthenon Just Got Two New Stones — and a Lesson in As-Built Memory
Two marble blocks close a 220-year gap on the Parthenon — and show why readable geometry, open protocols and re-scan discipline outlive any vendor cloud.
The robot arm that put its motors in the basement
Disney Research's fluid transmission delivers 4.5 Nm at 120 grams by moving the motors to the torso — and moves robot-cell safety from software into hardware.
Switzerland's 30% solar cell — and the number that isn't on the roof yet
EPFL and CSEM certify 30.02% in a perovskite-silicon triple-junction solar cell — the physics behind the record and what it means for BIPV façade specs.
Spain Won With a Pipeline, Not a Transfer Window — Your BIM Stack Is Too
Spain beat Argentina 1-0 with a nine-year pipeline, not transfers. The same logic decides whether your Archicad-Speckle-IFC stack survives its vendors.
Arduino is a Qualcomm company now — what that changes on a studio bench
Arduino is now a Qualcomm company. What that changes on a studio bench — and how arduino-cli, sketch.yaml pinning and sha256 manifests keep builds reproducible.
Four Bridges, 130 Years Old, Rebuilt for 2150 — The Design Life Nobody Asks You For
Network Rail's four Forest Gate bridges are specified to last until 2150. What a written design life — and a staged replacement sequence — should teach your office.
Blade Runner at 40 is a dependency graph — read the topology, not the film
Forty years on, Blade Runner endures because its dependency graph has leaves no one can replace. A topology reading from PAZ Kaffi Cyber-Punk News.
