1. Preface: It's been a while since I've updated the AI learning map on my blog. It's not that my interest in AI has waned; quite the contrary. Many ideas and explorations have already taken shape in my mind. The real reason I've stopped is actually very simple: many practical scenarios ultimately involve the "paid AI" model.

1. Blog Knowledge Map - Featured Navigation: This knowledge map serves as the blog's sole main entry point, containing only articles with systematic, methodological, and practical value. It aims to help new readers quickly grasp the author's core technical threads and thought framework. Several areas within the blog have already formed relatively complete knowledge systems…

1 Introduction In my previous multi-active architecture deployment practice (see: Home Data Center Series WordPress Multi-Active Architecture (Simplified Version) Implementation Plan in Personal Blog), Cloudflare's health checks are the key to achieving node...

1 Introduction In the previous article (see: Home Data Center Series WordPress website uses Simply Static plugin to achieve site static), I introduced in detail how to use Simply Static on WordPress…

1 Background Introduction The original idea of developing a WordPress multi-active solution was actually very simple: the Internet at home was cut off by the telecommunications company for three days without any warning (see the article: Home Data Center Series From this time when the Internet was cut off at home, I talked about my current personal blog…

1 Introduction Since my blog uses a special WordPress active-active architecture (the macmini in the home data center is the primary write and secondary read node, and the VPS in Chicago Racknerd is the primary read node), once the macmini node has content changes (all blogs…

1 Introduction In the previous article (see: Home Data Center Series: Using X-WRT to Transform Retired Small Hosts: An Alternative Choice for Main Routers), I used an idle J2900 x86 small host to tinker with the soft router. It worked fine, the performance was more than adequate, and the system was stable...

1 Introduction I have always used iQuick as the main router in my home data center. Its main advantage is that it supports multi-dial function (for the detailed concept of multi-dial, please refer to the article:). Because my home telecom broadband supports up to 3 dials, I can obtain 3 public network IPv4 addresses at the same time, which is very useful for people like me who have multiple line access...

1 Introduction When deploying a WordPress multi-active node solution, a crucial technical point is read-write separation: that is, all operations involving "writing to the database" (such as publishing articles, modifying content, modifying plugin configuration, submitting comments, etc.) are uniformly routed to the primary write node for completion, while other nodes...

1 Introduction I have always wanted to build a synchronously updated static copy for a dynamic blog based on WordPress. On the one hand, it is out of the pursuit of "full site cache" and "always online" capabilities - after all, early blogs have not yet achieved disaster recovery and dual-active deployment, and WordPress itself...
