Welcome to Felix XIO

This site is a technical notebook for cybersecurity, systems, networks, and practical engineering.

I use it to document:

• security tooling and workflows
• systems and distributed computing notes
• infrastructure, automation, and debugging
• selected UNSW course material when it is worth preserving

The goal is simple: publish work that stays useful after the immediate problem is over.

这个网站是我在网络安全、系统、网络和实用工程方向的技术笔记本。

内容包括：

• 安全工具与工作流程
• 系统与分布式计算笔记
• 基础设施、自动化与调试记录
• 值得长期保留的 UNSW 课程材料

目标只有一个：发布那些在问题解决之后仍然有价值的内容。
