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…
Awakening of the Voice (Part 5): The Original Key Myth—Why Sometimes Singing in a Different Key Can Better Express Your Own Voice
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.

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.

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…
The Awakening of Sound (Part Two): The Misunderstood Sound—The Illusion of High Notes and the Hallucination of Low Notes
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.
