Blind Spot Mirrors: Which Type Actually Works?

Why Electricians and Lawyers Used to Be the Same Thing

When you call a plumber and a lawyer, you're interacting with two very different social categories — but that wasn't always the case. This episode traces the bizarre history of how we divided work into "professions" and "trades," from medieval guilds where master masons outranked notaries, to Adam Smith's class-based philosophy, to the Flexner Report that shut down half America's medical schools. We explore how the AMA and ABA deliberately restricted entry to raise incomes, why electricians now train as long as CPAs but get treated differently at dinner parties, and whether AI is about to shred the whole distinction for good.

The Fifteen-Cent Screw That Stops Server Builds

When a ZFS pool failure turns into a battle with a seized M.2 screw, you realize the real enemy isn't bad sectors—it's a fifteen-cent piece of threaded metal. This episode explores why tech repair projects almost never fail on the big things (filesystems, kernel configs) but on the small things: thermal pad thickness, screw inventory, and whether your headlamp batteries are charged. We break down the three categories of missing parts that ambush every rebuild and explain why "knowing how to fix it" and "having what you need to fix it" are two completely different competencies.

The Screw That Beat Me for Two Hours

When a single M4 screw stopped a home server upgrade cold, we dug into the engineering behind seized fasteners. Thermal cycling, galvanic corrosion, thread locker, and bit hardness all conspire against you. Learn why locking pliers beat precision drivers — and what to keep in your kit before your next build.

Solving the Bulk Redirect Problem for System Migrations

When you're migrating from one inventory system to another and QR codes and barcodes are already printed and stuck to physical boxes, you can't just push an update. The redirect layer becomes operational infrastructure. This episode explores the landscape of tools for managing bulk redirects — from simple pattern-matching with Traefik and Redis to programmable routing with Pomerium and Kong. We break down the three layers of the redirect problem and what actually works when you're dealing with millions of mappings and a deadline.

Cloud Brain, Local Fingers: Decoupled Home Assistant

What if your Home Assistant brain lived in a cloud VPS while the Zigbee coordinator stayed in your apartment? This episode unpacks the "decoupled control plane" architecture — cloud orchestration with local actuation. We explore the traffic flow over Tailscale tunnels, the 30-80ms latency tradeoffs, and why fallback Zigbee bindings can keep lights working even when the Frankfurt server goes dark. Plus: why Matter devices complicate the picture, and the hard rule that life safety stays local.
