1 Introduction At the end of the first article in this series (see article: Building a “Lightweight Knowledge Index” for a Blog (Part 1): Structure Design and Build Process), we have already converged the entire knowledge index system into a clear structural model: from article acquisition, content organization, to relationship building and result output...

1 Introduction Recently, I have been thinking about what new features can be added to the blog structure, such as the content structure prompt added below the article page (see article: From Content to Structure: A Low-Cost Approach to Blog Context Evolution). However, there are still many further capabilities, such as: automatic content recommendation...

1 Starting with “Spring of Seoul” Recently, I watched a 2023 South Korean movie “12.12: The Day” (Spring of Seoul): The film is adapted from a real historical event that occurred in South Korea on December 12, 1979—the "December 12 Military Coup", telling the story of the military seizing power and terminating South Korea's brief democratization process...

1 When a Website is No Longer Just Pages In the blink of an eye, it is already 2026. Looking back, this blog of mine has been running stably for more than two years since it was first built. The time is not particularly long, but it is enough for me to fully experience a journey from “setting up the website” to “starting to repeatedly think about the web...

1 Starting from an Unobtrusive Anomaly I believe that for many personal bloggers, the fact that their websites do not display favicon icons in Bing's search results should be a quite “familiar” problem. You don't even need to study it deliberately, just search in Google...

1 Introduction Recently, I watched a movie about the mathematician Ramanujan, "The Man Who Knew Infinity": This movie does not try to explain those difficult mathematical formulas to the audience, but repeatedly emphasizes a more intuitive question: what happens if a genius is born in an unsuitable era? Ramanujan was a...

1 Preface I believe everyone has seen a scene in movies and TV dramas that has almost become a “conditioned reflex”: on the monitor, the ECG suddenly flattens into a straight line; the atmosphere suddenly freezes, the doctor shouts, and the defibrillator comes into play; “Clear!”—after the electric shock, the ECG waveform miraculously re...

1 Starting from the Black and White Keys: The Smallest Structural Unit of the Music System In the previous article (see: Awakening of Voice · Foundation (I): Pitch Structure and Auditory Stability), I mentioned an important fact: the fifth relationship describes the auditory closeness between pitches. For example, C and ...

1 When Stability Begins to Require Maintenance The direct reason for writing this article is that a cross-border transit service provider I have long relied on (which I have always considered to be the most professional technically) finally collapsed recently, causing the access architecture that had been running stably for years to instantly fail. This change forced me to re...

1 Before Talking About Bass, Mid, and High I believe many music lovers have seriously thought about such a question: does their voice count as bass, mid, or high. This question does not seem complicated, and it even seems that an answer can be obtained through a simple vocal range test: how high can you sing...
