Watching a node boot, then a second mesh with no bridge

“A node that does work without leaving a trace is a bug. Start with the trace; everything else hangs off the spine it gives you.”

Hunting a connection leak the soak test wouldn't explain

“When a leak resists reasoning, stop reasoning and instrument it. A spawned-vs-finished counter found in minutes what hours of reading the reap path missed.”

Open-sourcing the Rust Distributed Mesh

“Not a library to take and use. A kit to read while you're paying the same costs I just paid.”

Chaos-pass replaces tests-pass

“Steady-state-only passing is insufficient. The cluster has to survive being broken.”

Four days into the soak, the RAM was still climbing

“The worst CPU offenders had zero active peers. That's the fingerprint of dead-state accumulation.”

Flamegraphing your way out of "this can't possibly be right"

“Comments lie. Flamegraphs don't.”

When 18 nodes pegged my 80-core box at 100%

“Three obvious wins got the host from 100% to 35%. Still wrong, just less wrong.”

Why I'm building a distributed mesh substrate in Rust

“I want to feel where the iroh-as-substrate story breaks at small scale before betting a real product on it.”
