Namespaces are the unsung kernel feature behind every container runtime. This post walks through the eight namespace types, how they appear in the kernel, and how Docker, Kubernetes, and runc compose them into the isolation boundary you trust in production.

How to ship small language models to local edge devices without falling into the usual latency, memory, or quality traps. Covers quantization, llama.cpp, batching, and the operational metrics that actually matter.

A practitioner’s guide to designing circuit breakers in service meshes, with concrete patterns for failure detection, isolation, and recovery in production microservices.

Learn how to apply the USE method to systematically diagnose performance bottlenecks in production systems by checking utilization, saturation, and errors for every resource.

A hands-on build guide for a portfolio-grade search engine: tokenize documents, build an inverted index, rank with TF-IDF, and ship something that actually works. Includes runnable code, tests, and a roadmap of upgrades that turn the toy into production-flavored work.
