How we cross-compiled three AuthOS binaries with cargo-zigbuild, kept Docker for packaging, and cut our warm publish builds from about 15 minutes per variant to 90 seconds.
What Actually Limited AuthOS on SQLite
AuthOS appeared to hit SQLite's limits at 130 requests per second. Moving Argon2 work, audit writes, activity updates, and overload control changed the result—and exposed what …
Serializing SQLite Writes in a Parallel Rust Test Suite
How a Rust SSO test suite exposed SQLite write contention, why timeouts and raw transaction SQL did not solve it, and how one writer connection stabilized eight parallel …
Serializing SAML Certificate Rotation with a PostgreSQL Row Lock
A concurrent integration test exposed a check-then-act race in a Rust SAML key-rotation handler. A transaction, a lock on the shared service row, and a partial unique index …
From a Rust Benchmark to an SSO Platform for 500,000 MAU
How AuthOS grew around a small Rust core, and what its measured budget-VM throughput means under an explicit 500,000-MAU traffic model.
How Far AuthOS Got on One CPU and 1 GB of RAM
I rebuilt the AuthOS SQLite benchmark, untangled two limits outside the database, and measured its useful operating point inside a budget-shaped VM.
