  • Why SDD Breaks Down in Microservices—Part 3: Distributed Systems Need Distributed Context

    This story was originally published on HackerNoon at: https://hackernoon.com/why-sdd-breaks-down-in-microservicespart-3-distributed-systems-need-distributed-context.

    In microservices, spec-driven development with an LLM needs architecture-level context, not just local specs. This article shows how machine-readable service contracts and a plan-first workflow (archspec, a Claude Code plugin) give the model that context: it resolves cross-service rules while planning, catches them before any code, and turns each one into a test. It's a practical way to make AI-driven specs hold up across services.

    Why not make a pixel art modifier so they become like terrain or game assets? And here is what I came up with. You build the pixel art as you wish. Then you modify it so it becomes a design.

  • A Unified Namespace Determines Your Historian Schema, Not the Other Way Around

    Most teams design the historian first and connect it to a Unified Namespace later. This article argues the reverse: the UNS owns identity, so it should dictate the historian schema. That means storing tag identity in a relational namespace table with surrogate keys and keeping history in a narrow hypertable. The result: tag renames, hierarchy changes, and churn happen without rewriting history.

    awk is the tool that does what grep, cut, and sort cannot do alone — filter by field value, perform arithmetic, count with associative arrays, and format output, all in one pass. This article covers how awk thinks, every practical flag and built-in variable, and real security patterns, including UID 0 detection, HTTP status filtering, brute-force source ranking, and exfiltration hunting in access logs.
