Building a “Lightweight Knowledge Index” for the Blog (Part 6): Guessing What You Think—The True Introduction of Embeddings
1 Why Do We Still Need “Guess What You Want” Because it overlaps with the newly added "Right Menu" feature on the article page, after some consideration, I decided to remove the "Guess What You Want" feature. However, this article is still kept as a reference example for implementing similar features. In previous articles (see: Building a "Lightweight Knowledge Index" for My Blog…
Building a “Lightweight Knowledge Index” for the Blog (Part 5): Article Series Navigation and Reading Path Design
1 From “Single Reading” to “Continuous Reading” A major difference between my blog and traditional personal blogs is that there are many highly “continuous” series of articles: such as the “Cloudflare Series”, “Awakening of Voice” series, and also including the “Building a ‘..." series in which this article resides…
Cloudflare-Based Emby Media Showcase Site Transformation: From Public Release to Access Experience Optimization
1 From Media Server to Media Showcase Site For people who have collected a large amount of movie and TV resources at home, they probably have more or less the idea of showing their collected resources to everyone—of course, “showing” here is simply looking at posters, looking at the scale of the collection, and seeing what movies and TV shows are collected…

Building a “Lightweight Knowledge Index” for a Blog (Part 3): Implementation of JSON Structure and Generation Script
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...
Building a “Lightweight Knowledge Index” for a Blog (Part 2): Structural Design and Build Process
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...
Making Embedding an Infrastructure: Deploying Independent Embedding Services in PVE + LXC
1 When Embedding Moves from Experiment to Basic Capability In the previous article introducing RAG, I introduced that the core tool for vectorizing segmented text is the "embedding model" (see article: Understanding RAG from Scratch (Part 1): Principles and Complete Process Analysis), and also in the subsequent...
Understanding RAG from Scratch (II): Running a Local RAG Demo on Mac mini—A Practical Guide to the Minimal Architecture
1 Preface In the previous article (see article: Home Data Center Series - Understanding RAG from Scratch (I): Principles and Complete Process Analysis), I introduced the theoretical five-step process of RAG: “Chunking → Vectorization → Vector Storage → Retrieval → Answer Generation”; subsequently...
When Whitelisting Becomes the Norm: Trends and Sustainability Analysis of Personal Cross-Border Access
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...
