Hi , I'm WindDevil, a systems engineer at Cambricon (Beijing). I work mostly in C, C++ and Rust, across Linux user space and the kernel: system calls, POSIX APIs, device drivers, and the toolchains that glue them together.

I like turning hard-won debugging knowledge into reproducible practice material, and that is what most of my repositories exist for:

• clings — 185 hands-on C exercises across 20 topics, from Hello, C! to pointers, memory, the preprocessor, undefined behaviour and C11/C17 features.
• lspling — 140 Linux/POSIX system programming exercises, arranged chapter by chapter after Robert Love's Linux System Programming (2nd edition).

Both are spec-driven: a single specification generates the initial exercise, the reference solution and the reset template, a dependency-free Python CLI drives the daily workflow, and CI proves that every exercise starts unsolved while every answer passes.

Beyond that I write Rust drivers — mainly for the Intel igb network controller, with ArceOS as the unikernel playground — and tinker with embedded boards (ESP32 + RT-Thread, STM32). I keep notes at my blog (in Chinese).

I'm also interested in how AI reshapes everyday engineering workflows. Claude Code, Codex and Hermes are part of my daily loop — for code review, test generation, and turning one-off debugging sessions into reproducible pipelines.

During my Master's I collaborated with Huawei HiSilicon on research through an in-group project. I also interned with Qualcomm's IoT team, and on a joint project between Quancheng Laboratory and Tsinghua University, where I worked on ArceOS-based OS and driver infrastructure — the line my igb-driver and arceos_igb_driver repositories continue today. I received my Master's degree from UESTC (University of Electronic Science and Technology of China) and my Bachelor's degree from GUET (Guilin University of Electronic Technology).
