Plain-language engineering articles on redundancy, CAP theorem, cache, idempotency, reliability, and system design by Pawan Bisht (277pawan).

• Cache Really Matters

  What a cache is, where it shows up, and how write-through, write-back, and write-around trade speed, consistency, and data-loss risk.

• CAP Theorem — Full JSON Block Demo

  Interactive demo article using every engineering blog block type: video, code, polls, tables, and SEO fields. Learn CAP (Consistency, Availability, Partition tolerance) for interviews and system design.

• Redundancy in Software Systems

  What redundancy means in engineering, when to add spare capacity vs duplication, and how it improves reliability without wasting cost.
