Docker Basics, Intermediate, and Advanced
Having worked with CentOS for many years, content may not apply to macOS or Ubuntu users in some cases.
You can refer to the documentation from Tsinghua University for installation guidance: https://mirrors.tuna.tsinghua.edu.cn/help/docker-ce/
Installation Due to unknown mysterious forces, domestic Docker installation is recommended to set the cloud vendor’s repository address. Here we recommend using Alibaba Cloud.
Set Repository Source Address yum install yum-utils device-mapper-persistent-data lvm2 && \ sudo yum-config-manager --add-repo http://mirrors.

Website Acceleration and Domain Settings
Due to slow access to GitHub Pages from within the country, the author applied for a personal domain and purchased CDN acceleration services from a domestic cloud host provider. During the configuration process, the author encountered an issue where the www subdomain could not be accessed, which was ultimately resolved by deleting the generic domain DNS record and setting up a second-level domain separately.

A custom allocator can improve performance, increase memory utilization efficiency, and address the issue of frequent, small memory allocations.
Antecedent Recently, I’ve been working on the development of network data packets, requiring frequent allocation and release of small blocks of memory. Initially, I considered using a memory pool, reviewing several existing ones and discovering this: https://github.com/cacay/MemoryPool When looking at the interface, I was quite puzzled by how the memory pool’s implementation was a bit strange.
