Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
We wrote pretty postmortems for two years and kept hitting the same incidents. Here's what changed when we started writing ugly ones.
Practical patterns for Terraform modules at scale: versioning, composition, testing, and avoiding the monolith trap.
Step-by-step debugging of a production Linux server hitting 100% CPU. From top to perf to the actual fix.
Battle-tested prompt patterns from running LLM features in production: structured output, chain-of-thought, and graceful failure handling.
A real cost audit uncovered idle load balancers, oversized RDS instances, and forgotten snapshots. Here's what we found and how we fixed each one.
A real walkthrough of shrinking bloated Docker images from 1.2GB to 240MB using multi-stage builds, Alpine, and dependency auditing.
A real-world model fallback guide for customer-facing AI systems, covering how one team preserved response quality and support SLAs during a partial provider degradation.
A practical artifact promotion guide for CI/CD teams that were tired of hearing 'it passed in staging' after production behaved differently because the release was rebuilt.
A hands-on RDS restore drill guide for small cloud teams that thought backups were covered until a timed restore test exposed missing steps, DNS confusion, and stale credentials.
A practical systemd drop-in guide built from a real operations problem: vendor unit files kept changing, but the team still needed consistent restart, environment, and logging behavior.
A real-world Terraform module version pinning guide for platform teams that want safer upgrades, clearer ownership, and fewer broken pipelines after shared module releases.
A practical embedding model upgrade guide for RAG systems, built from a real support-search migration that initially reduced answer quality instead of improving it.
