Preface A few days ago, I suddenly received a reminder from Tencent Cloud that the domain name SSL certificate has expired: This domain name is used by me to deploy derp (tailscale relay server on the cloud host. If you are interested in related content, you can read the previous article: Debian series build tai...

Preface Since the beginning of June, WARP has been almost completely destroyed in China. For a large number of friends who use WARP as their main learning method, it is like a devastating blow. Even I, who only use WARP as a backup method, have been affected and have to consider other backup methods. However, well…

Foreword For chatgpt, I have been using the app version on Mac, because it has a free daily quota, which is more than enough for a light user like me, and it is difficult to exceed it. However, when studying the AI plugin "AI En…

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...

Preface With the official completion of the ten-part cloudflare series tutorial (these ten parts are equivalent to the main series, if there are more in the future, they can only be regarded as extra-partners, and it does not affect the fact that there are only ten parts in the main series~), I think I should also open a separate summary post for cloudflare: it will include the series tutorials and…

Preface Actually, I originally wanted to end the CF series tutorials at the ninth part "Zero Trust". After all, in the Book of Changes, nine is called a "big number", which means the largest and most perfect number between heaven and earth. It is said that there are nine layers of heaven, nine nines return to one, nine nines return to one, nine nines return to one, etc. Therefore...

Introduction Because I have written several articles about the basics of AI before, I am thinking that it is time to release an AI learning map: first, I can sort out my thoughts and clearly know which knowledge points I have learned and practiced specifically, and it can also serve as my own AI learning notebook; second, it can also allow people who are destined to…
