日新笔记 is Quentin’s engineering notebook: home infrastructure, Proxmox VE, AI systems, and technical problems that reward careful verification.
The Chinese name comes from Daxue: “苟日新，日日新，又日新.” The point is not novelty for its own sake, but the discipline of renewing one’s understanding through repeated work.
Chinese is the default language; English versions appear where they are useful.
