All of my long-form thoughts on programming, leadership, product design, and more, collected in chronological order.
A technical deep dive into the Dockerfile and docker-compose setup behind functional infrastructure testing — including SSH access, network segmentation, systemd mocking, and downloadable reference samples.
A Docker-Compose-based functional testing approach that validates multi-environment Ansible roles using real inventories, lifecycle semantics, and SSH — without cloud dependencies.
rf_action_logger introduces JSONL-based action logging that turns Ansible executions into machine-readable, auditable data — designed for security-sensitive and large-scale IaC environments.
rf_nested_vars introduces nested variable hierarchies, explicit customer and environment scoping, and deep-merge semantics for large-scale, multi-tenant Ansible repositories — proven in production environments.
Tag-based execution breaks down in large IaC codebases. This article introduces a lifecycle-driven role pattern (install, update, remove, ignore) that replaces tags with explicit delivery semantics — improving safety, clarity, and long-term maintainability.
Mitogen dramatically speeds up Ansible, but parallel execution can break hidden provisioning dependencies. This article explains why global parallelism fails in practice — and how selective strategy switching preserves both performance and correctness at scale.
