The third optimization of the blog architecture: WordPress dual-active node adjustment and database import considerations.
1. The Reason for the Third Optimization of the Blog's Active-Active Architecture A few days ago, I was preparing to perform a routine maintenance operation on the Mac mini node in the blog's active-active architecture: upgrading the Portainer version. However, a seemingly insignificant small problem ultimately caused the entire node…
声音的觉醒(五):原 key 迷思——为什么有时候“不按原 key 唱”,反而更能唱出你自己的声音
1. When we get used to "the original singer is the standard," we forget whose voice it is. Most people, when they start singing, implicitly have an "invisible standard" in their minds—whatever key the original singer sings in, we should sing in the same key. It seems that only by completely copying the original can we be recognized…
声音的觉醒(四):科班声乐体系与普通人自学唱歌的天然断层——语言、方式与结构的差异
1. Introduction Having recently achieved initial success in "larynx control," I've been reflecting on the detours I've taken over the past two years in researching "singing"—it wouldn't be an exaggeration to say it was a winding, circuitous road. The fundamental reason for these many detours was that I was initially misled by the teachings of various online "vocal teachers"...
声音的觉醒(三):”高位置”的误区与科学解读
1. Entering the 'High Position': A Mythologized Concept of High Notes Many people who have studied singing and watched countless instructional videos are familiar with the term "high position." A quick search on Bilibili (a Chinese video-sharing website) for "high position" yields a screen full of tutorials, each titled "Unlocking the Secrets to High Notes," "Singing High Notes Easily..."
Why is WordPress more prone to "Error establishing database connection" on entry-level VPS? A systematic analysis from database to architecture.
1. Introduction I've been using a base-level VPS (US$39/year) from Racknerd's Chicago data center to build the "read-only node" in my blog's active-active architecture for about half a year now. Over this time, the VPS's overall stability has been quite good…
声音的觉醒(二):被误解的声音——高音的错觉与低音的幻觉
1. Introduction In the past two years of dedicated study of singing, I encountered a very thorny problem: my ear's ability to distinguish sounds couldn't keep up with my body's vocal production. Professional vocalists, upon listening to an original recording, can often immediately determine exactly how high a high note is and whether a low note is truly that deep; but for someone like me…
Why did I migrate from self-built Umami to Umami Cloud? — A discussion of the trade-offs between self-deployment and managed services
1. Introduction In previous articles, I wrote two about building your own Umami: one on setting up version 1.33.1 (see article: Docker Series: Building a Website Traffic Monitoring System Based on Umami), and the other on setting up version 2.11.3 (see article: Home Data Center…
A Systematic Review of Buddhist Theory (Part Two): The Tree of Awakening—The Development of Buddhist Theory: Dependent Origination, the Five Aggregates, and Causality
1. Introduction In previous articles (see: Spiritual Nourishment Series: A Systematic Review of Buddhist Theory (Part 1): From Interest to Rational Understanding of Buddhism), we discussed the compatibility of Buddhism and science—although their paths differ, both use observation as a method and awareness as their ultimate goal. Science explores the laws of the world outward, while Buddhism…
Awakening of the Voice (Part 1): The Instrument Within the Body—Rediscovering the Essence of Singing
1. Introduction I've loved singing since I was little. The first song I seriously learned, I remember, was "Green Apple Paradise" by the Little Tigers. To memorize the lyrics, I listened to it on the radio and wrote it down line by line in my notebook—much more self-disciplined than I was doing dictation at school. However, I've never…
A Systematic Review of Buddhist Theory (Part 1): From Interest to Rational Understanding of Buddhism
1. My Starting Point: Why I Choose to Start with Buddhism? Human beings are inherently contradictory: they can be powerful enough to transform mountains and rivers, undertake massive construction projects, explore the heavens and the seas, even leaving footprints in space; yet they can also be fragile enough to fall into self-pity, depression, or even resentment due to insomnia, a word of blame, or a period of loneliness…
