Property-Based Testing: Test the Rules, Not Just the Examples
Property-based testing moves beyond hand-picked examples by testing the rules that should remain true across many possible inputs.

Mobile, Offline, and Cross-Domain Tracking Patterns in xAPI
Valid xAPI statements are not enough. This article shows how to instrument video, assessments, and branching scenarios with consistent verbs, stable IDs, and one registration so learner behavior stays reconstructable later.
Context Compaction: Keeping the Hot Path Fast
Most long-running agent failures are context failures, not reasoning failures. This article explains how context compaction keeps the hot path small, preserves recoverability, and turns memory management into an operational policy.
Refactoring: Improve Continuously, Not Occasionally
Tests do more than catch defects. They document behaviour and give developers the confidence to change software safely.
Instrumenting Video, Assessments, and Branching Scenarios with xAPI
Valid xAPI statements are not enough. This article shows how to instrument video, assessments, and branching scenarios with consistent verbs, stable IDs, and one registration so learner behavior stays reconstructable later.
Summarization for Long-Running Agents: Compression Without Losing the Plot
Long context windows do not solve long-running agent state. This article explains why summarization is really state compression, how to design structured summaries, when to trigger compaction, and how to detect behavioral drift before bad memory causes wrong tool calls or broken constraint handling.
Refactoring: Improve Continuously, Not Occasionally
Every file you touch gives you a chance to make the next change easier.
Designing an xAPI Data Strategy from KPIs Backward
Most xAPI failures begin before the first statement reaches the LRS. This article shows how to start with KPIs, define report grain, choose decision-grade events, and lock an event contract that still supports trustworthy analytics months later.
How Retrieval Fits Into Agent Memory Without Becoming Memory Itself
Retrieval is not memory. In production AI agents for developers, retrieval should stay a read path to external systems, while memory remains a write path for learned continuity like preferences, instructions, and successful procedures.
Algorithm Speed: Solve the Right Problem First
The fastest code is rarely the most optimized. It is usually built on the right algorithm.
