During a 48-hour engineering task, I wrote down one sentence: “At this point, I’ve spent half the time designing, researching, understanding the requirements, judging the boundaries, and developing my taste and intuition. I haven’t started writing code.” The task began as a limited feature. After I kept discussing it with AI, it quickly grew a product model, system boundaries, and a complete design. Every step had a rationale. Every piece connected to the next. I could feel myself thinking faster and farther, holding more layers in mind at once. ...

Calling Claude Tag a Slack bot misses its most consequential product decision. It turns a channel into a place where an agent can be authorized, remember, and keep working: a team shares one executor; each task runs asynchronously in a thread-level sandbox hosted by Anthropic; Agent Proxy injects external credentials at the network boundary; and the result returns to the public thread with a traceable record. The Claude Tag documentation describes these mechanisms in unusually concrete terms. ...

At the beginning of 2026, my GitHub contribution graph stayed nearly blank for several weeks. A few months later, the same graph showed hundreds of contributions in a single week. In July, this blog published 55 articles in Chinese , while GitHub’s contribution calendar recorded 733 contributions. Those numbers prove neither quality nor user value, much less a business result. GitHub also makes clear that contributions may include qualifying commits, pull requests, issues, reviews, and other activity; the number cannot simply be relabeled as a commit count. GitHub’s profile contributions reference ...

I had only asked my second brain to organize the thoughts of a friend. It placed scattered notes in order by time, theme, and cause, then tried to explain how she thought about work, money, and freedom. A few thousand words later, I looked at the resulting portrait and realized that the person it had revealed most clearly was not her. It had shown me why I never stop building systems. ...

This piece is a thought experiment in simulated interviews. The respondents are synthesized from existential philosophy and behavior design perspectives—this is not verbatim dialogue from any real person. One June day, perhaps like this. I woke around noon. My phone lay on the pillow. First I checked the time, then the messages. Nothing was urgent, so I opened a short video. The algorithm did not require me to decide what came next. By the time I looked up, more than forty minutes had passed. ...

Put the Tip List Down for a Moment I began this article as a collection of Boris Cherny’s Claude Code habits. That version had a problem: social posts age with models and product releases, while fan-maintained collections tend to mix personal advice, previews, and impressive-looking statistics. A sharp opinion can become a historical footnote before the article reaches its readers. So I took the slower route. Product claims in this revision come from Anthropic or the official Claude Code documentation. Untraceable numbers, second-hand quotations, and claims of universal superiority are gone. Boris’s way of working remains an inspiration, but it is not treated as a specification. ...

The fifteenth tool list changed the question Over six months, I read roughly twenty or thirty “AI-era super individual” tool lists. Around the fifteenth, the pattern became hard to ignore: the lists differed far less than the competitive advantage each one promised. I use most of the tools they recommend. The problem was not that the recommendations were bad. It was that ten thousand builders could install the same stack in the same week. Their absolute capacity might rise, while the distance between them barely moved. ...

After Three Hours, What Is Left on the Table? I have had evenings that began with a modest intention: settle the angle of an essay. Soon I was discussing titles with AI, then business models, then the meaning of work. The conversation flowed beautifully. When I closed the window, the page was still blank. That does not make the conversation worthless. It reveals that exploration and execution are different kinds of work. ...

A Second Brain Is a Working System, Not a Larger Notebook Most note systems are built for a future reader called you. You save a link, polish a heading, add two tags, and trust that one day you will return. Usually, you do not. An AI-native second brain begins with a different question: What useful work should this note make possible? The answer might be modest: turn an inbox note into a project brief, retrieve your earlier judgment before a meeting, or draft an article from claims you have already verified. The point is not to make AI read everything. The point is to give it a narrow, legible field in which it can help without quietly rearranging your life. ...

On July 16, 2026, Google renamed NotebookLM to Gemini Notebook. The old name will remain in search results, screenshots, and habits for a while, but the product did not disappear. Google describes it as the same standalone research tool, now connected more closely to the Gemini app and, eventually, Google Search. The rename also marks a larger change: notebooks are becoming places where software can not only read sources, but also run analysis against them. ...

Flow State As I mentioned in my previous post on GTD and the Four Quadrant Rule Practice , I have been striving to enhance my focus and efficiency. Reflecting on the moments when I initially experienced the flow state, whether engrossed in a game or a novel, time seemed to stand still. The flow state is not just about the swift passage of time; it has profound effects on our lives, health, productivity, and even our sense of happiness. ...

GTD and the Quadrant Method Practice During the New Year holidays, I spent a lot of time reflecting. Alongside the growth and many merits over the past year, I also identified several shortcomings: Lack of proactive thought on prioritizing tasks A tendency to actively solve issues without much focus Difficulty in concentrating on completing specific TODOs Whenever I review my tasks, despite their number, I often feel a lack of clear judgment and thorough consideration. Sometimes, I might engage in a task because it seems crucial at the moment or out of a knee-jerk reaction, without truly assessing its priority or importance. This habit not only impacts my work efficiency but also prevents me from deep thinking and planning opportunities, which I aim to improve in the coming year. ...
