PostgreSQL VACUUM & Autovacuum Tuning: Preventing Table Bloat & Wraparound Crises
Default PostgreSQL autovacuum settings are dangerously conservative for high-write tables. Learn how to tune scale factors, cost limits, and worker thresholds to eliminate multi-gigabyte table bloat and prevent transaction ID wraparound outages.
High-Throughput Message Brokers: Redis Streams vs. RabbitMQ vs. Kafka for 50,000+ msgs/sec
Over-engineering with Kafka for simple message queues wastes infrastructure budget and engineering sanity. Compare Redis Streams, RabbitMQ AMQP, and Apache Kafka on a single Linux VPS: throughput, persistence, consumer groups, and operational overhead.
Zero-Cost Production Observability: Vector, ClickHouse & Grafana on a Single Linux VPS
SaaS telemetry pricing scales aggressively with log volume, forcing teams into dangerous log sampling. Discover how to deploy a high-throughput, zero-cost observability stack using Vector daemon, single-node ClickHouse, and Grafana on a budget Ubuntu VPS.
Node.js Memory Leak Forensics: Heap Snapshots, V8 GC Profiling & Container OOM Kills
Elusive memory leaks in long-running Node.js containers lead to unexpected Linux OOM killer terminations during peak traffic. Master heap dump capture, allocation timelines, and V8 garbage collection forensics.
Production Monorepos with Turborepo, pnpm Workspaces & Shared TypeScript Configs
Managing multiple microservices and frontend clients across fragmented repositories causes version drift and slow builds. Discover how to architect a high-velocity production monorepo using pnpm workspaces and Turborepo.
Zero-Public SSH: Hardening Cloud VPS Access with WireGuard Mesh Networks & UFW
Exposing SSH port 22 invites thousands of automated brute-force attacks daily. Discover how to bind sshd exclusively to an internal WireGuard mesh network and lock down public firewall rules with UFW.
