Building an efficient and secure random image API: A practical guide to Cloudflare Worker + R2 + KV
1 Introduction I didn't intend to write this article, but I suddenly jumped in because I suddenly got a little tired of "changing the background image of my blog manually and regularly". The background image of my blog has always been changed manually by me regularly (the image is stored on cloudflare R2)...
From QUIC to HTTP2: Building a more private and stable Cloudflare Tunnel solution
Foreword: Last week, I went back to my hometown to celebrate the Chinese New Year for a few days, so I didn’t have much time to write articles (actually, I had 2 articles in progress, but they were stuck in the middle and needed time to study and experiment), so this week’s content can be written in a short but necessary article to highlight the key knowledge points: Clou…
A bloodbath triggered by a "steamed bun": A record of the blog access anomalies caused by upgrading tailscale these past few days.
A few days ago, I saw that the devices running TailScale were running all kinds of strange versions of TailScale. Due to my obsessive-compulsive disorder, I changed the version of TailScale for all the devices running TailScale (except Qnap NAS and OpenWRT, because these two official versions are currently...
Solving the WordPress AJAX protection challenge: Using Cloudflare Tunnel to "distribute" normal website access traffic from attack traffic.

Even I, who only use WARP as a backup method, have been affected and have to consider other backup methods. However, well…
This section discusses the core concepts and practices of accelerating website access using Cloudflare CDN, focusing on well-known concepts such as "custom IP," "optimized IP," and "optimized domain."”
Preface I didn't want to write this article originally, because fundamentally speaking, the concepts of "self-selected IP", "preferred IP", and "preferred domain name" are not official terms. To put it nicely, they are "folk remedies", and to put it bluntly, they are "heresy" (Old Kai said it truthfully). I have also specifically discussed them in previous articles...
A Complete Guide to Building a Personal Blog from Scratch (Minimum Cost)
Preface It has been almost exactly one year since I officially published my first article on August 25 last year (the one on August 7 was just a test). In this year, I can’t remember how much knowledge I have learned and how many bottomless pits I have stepped into in order to run this blog. Today, although it can barely be considered…
