Building RAG Pipelines: Vector Databases, Chunking Strategies, and Retrieval Optimization
A naive RAG implementation produces mediocre results. The difference between a demo and a production-quality system lies in deliberate choices at every layer: embedding model selection, chunking strategy, hybrid search combining semantic and keyword retrieval, and cross-encoder re-ranking. This guide covers the engineering decisions that separate reliable RAG pipelines from prototypes.
DNSSEC and DNS-over-HTTPS: Hardening Your Resolution Infrastructure
DNS was built for convenience, not security. DNSSEC and DNS-over-HTTPS address two distinct problems — data integrity and query privacy — and together they transform DNS from one of your most exploited attack surfaces into a hardened, monitored component of your security architecture. This guide covers zone signing, key management, DoH and DoT deployment, and resolver hardening.
