Quick Navigation Start with the long read: 9 sections in the body above. 1 archived notes this month, filed under 1 themes: Daily Notes and Everything Else · 1 Prologue: A May Without flomo For the entire month of May, I did not write a single flomo note. I barely posted to my feed either. This was not laziness. It was a conscious decision. I had already decided on April 30 that I would stop. The reason is simple: I no longer felt I needed it. Or more accurately — could it have a better form? I want to use my own product. It is not perfect yet, but I want to fully think through and ship the thing I have in my head. The remaining steps are few. It is close. ...

On the edge of a cliff, all logic fails. Only intuition can connect with the world. I wrote this sentence one night in Lhasa. Finding it now, I feel it can serve as the entry point to this review. Over these past fourteen months, I’ve been living on the edge of cliffs — almost literally. Encountering ice slopes on ACT mountain trails with drops beside me; every step at the altitude of Genie Sacred Mountain requiring all my strength; riding a motorcycle around the outer circle of Angkor Wat for three days with a splitting headache, yet not stopping. But I also know that those “cliffs” were more often internal. They were the cosmic-level monologues in one’s own mind after getting drunk late at night in a foreign country, with the world fading into the background. They were that night in Shenzhen, standing under DJI’s light beams, feeling like I hadn’t even reached the starting line. They were a certain morning at the end of 2025, suddenly realizing that exploration itself no longer provided enough traction, without knowing where the next fulcrum would be. ...

Introduction and self-positioning Annual Preface and Background 📅 Hi! 2025 ~ TIP: This article has a high density of information and is highly subjective. I have tried to include fewer opinions and more descriptions of my experiences, including my own experiences traveling, reflections on things I have experienced, and some experiences in making products. Experience is valuable, and I hope to leave more room for you to be touched and think. Just choose the content that interests you from the TOP. ...

What actually happened here How large a team does it take to rebuild a four-year-old blog with 120+ posts — content architecture, operations, all of it? My answer, delivered over the first half of this year: one person and a crew of agents with clearly divided jobs. “Crew” is a working metaphor, not a fixed headcount of digital employees. As of July 2026, the repository contains seven Claude skills and four workflows whose names begin with seo-; Claude Code, Codex, the Claude jobs inside GitHub Actions, and temporary review sessions are started only when a task calls for them. The human owns judgment, boundaries, and the final signature. Agents own scoped work that can be tested. The result is the site you’re reading — cubxxw.com . It isn’t merely a redesign. It turned “a blog” from a static site into a system that generates a daily report, prepares fix proposals, and exposes its own search interface. ...

The answer first: a clean technical audit was not the same as demand In July 2026, I put the previous four chapters’ five-layer GEO model against my own blog. The useful result was not “technical SEO is perfect.” It was narrower: The tested homepage passed every Lighthouse SEO audit, while a three-month Search Console snapshot showed 878K impressions and only 852 clicks. Once I segmented the data, most clicks came from a small technical core, while many impressions came from unrelated long-tail queries. ...

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. ...

These go: instructions in the Go source code && go automation tools Developers have a strong tendency to automate repetitive tasks, and this also applies to writing code. Boilerplate code may include operations such as setting up a basic file structure, initializing variables, defining functions, or importing libraries or modules. In some cases, packages provide boilerplate code as a starting point for developers to build from, typically generated after the code behavior has been configured. Although boilerplate code may be necessary and valuable to application functionality, it can also be wasteful and redundant. For this reason, there are many tools that minimize boilerplate code. go generate is a command line tool for the Go programming language that allows automatic code generation. You can use go generate to generate easily modifiable code specific to your project, making the tool powerful at reducing boilerplate. go generate This command is usually used to automatically generate code before compilation. It can be used to create repetitive or patterned code, thereby saving time and reducing errors. Think about it, in what situations would this be particularly useful? 🤔 ...
