This is where I record my ongoing observations on AI, software engineering, product, business, and personal productivity systems. What interests me more is the structural change behind the tools: how technology reshapes organizations, business, and individuals.

Both show resilience, and both have their own imbalances.

The key boundary is whether the loop changes task outcomes, processes, or the mechanisms that generate the next generation of capabilities.

It is about building engineering standards that can compound over time and naturally absorb progress in LLMs and infrastructure. Read full article: {% endupdate %} {% update date="2026-01-18" %} ## W03 - Lessons from Advanced Troubleshooting For hard frontend problems, distinguish between hidden code defects and uncertain runtime behavior: first use a workaround to contain the risk, then rely on long-term observation to get closer to the truth. Technical explanations are not always complete.
