About
Notes on building, learning, and shipping software — full troubleshooting walkthroughs, reproducible configurations, structured series, and devlogs.
Content is organized into Series, browsable by Topic, or searchable with ⌘K. Everything is self-hosted within the DigitalScopeLab ecosystem — writing with long-term ownership. English articles are on the way; the full library is currently published in Chinese.
Writing directions
Server & Ops
Complete practice of building and maintaining self-hosted services — Nginx, HTTPS, process management, and monitoring.
Frontend & Rendering
Rendering pipelines, performance, and reading-experience engineering: Shiki, Mermaid, SSG, and design systems.
AI Engineering
LLM applications that actually work in personal projects: evaluation, cost, and reliability.
Devlogs
First-hand build records of Diagram and other products — the decision process matters more than the conclusion.
How it updates
- Updated at the pace of building: articles ship alongside product work — devlogs capture the process, articles settle the conclusions.
- Series publish chapter by chapter; registered chapters show their progress on the series page.
- RSS is the fastest way to subscribe; the homepage and archive are always there to look back.
