Here I record my ongoing observations on AI, software engineering, product, business, and personal productivity systems. I care more about the structural changes behind the tools: how technology reshapes organizations, business, and individuals.

The key question is whether the loop changes task outcomes, processes, or the mechanism that creates the next generation of capabilities.

It is about building engineering standards that compound over time and naturally absorb progress in LLMs and infrastructure. Read full article: {% endupdate %} {% update date="2026-01-18" %} ## W03 - Lessons from Investigating Advanced Problems For difficult frontend issues, distinguish between hidden code defects and uncertain runtime behavior: first use a workaround to contain the risk, then use long-term observation to get closer to the truth. Technical explanations are not always conclusive. Read full article: {% endupdate %} {% update date="2026-01-11" %} ## W02 - Rethinking Complex Abstractions AI coding is pushing software engineering from a “scarcity economy” to an “abundance economy.” Complex abstractions may no longer be cheaper to build. Tailwind’s dilemma also reveals that the old open-source model, which relies on attention monetization, is losing effectiveness. Read full article: {% endupdate %} {% endupdates %}
