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 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 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 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...

1 Preface Before, I wrote an article about dnscrypt-proxy deployment (see: dnscrypt-proxy (v2.1.8) multi-scenario configuration guide: from upstream deployment to downstream integration). The architecture at that time was: using Racknerd…

1 Introduction My previous blog architecture is a home data center (master node + hot standby node) + Tencent Cloud (disaster recovery node), which is a typical "single node read and write" solution. Since only the master node is responsible for processing database read and write requests on a daily basis, there is no need for real-time synchronization between databases: every time...

1 Introduction Since I purchased Racknerd's VPS and completed the big project of moving the disaster recovery node from Tencent Cloud's lightweight server to Racknerd's Chicago VPS (see article: The second reconstruction of the home data center series blog architecture: service issues caused by VPS relocation...

1 Introduction Actually, I have always wanted to build a stable and pollution-free DNS service in the intranet, specifically to solve the DNS pollution problem, for some applications that only need to solve DNS pollution, such as emby's tmdb plug-in, which cannot scrape film and television information normally, just because its A...

1 Introduction This article is the fulfillment of a goal I set for myself many years ago. The reason is that when I was testing the company's anti-D product, I needed to write a manual for a common traffic simulation tool (used to simulate various network attack traffic), so I thought: I might as well write one. As a result, I delayed it...
