}Projects & Open Source
Notebook-Translate
VS Code extension that translates Markdown cells in Jupyter notebooks into Chinese, with streaming output, provider switching (OpenAI-compatible, Ollama, Baidu), and OS keychain credential isolation.
mi-health-mcp
MCP server on Cloudflare Workers that pulls Xiaomi health data (sleep, heart rate, daily steps) for local LLM agents without running a local daemon.
Global Marine Gravity & Gradient Inversion
Inversion methods and open datasets deriving vertical gravity gradients from multi-satellite altimetry and mean sea surface models.
Personal Research & Automation Infrastructure
Self-hosted computational and automation environment spanning 10+ devices across Germany and China. Integrates a private DERP relay for cross-border connectivity, OpenClaw for multi-device orchestration, and Hermes for autonomous alert diagnostics.
trellis-for-research
Trellis spec templates and workflow for reproducible computational research, with task modes scaling checking effort from prototypes to durable models.
Recent writing
一次 Android chroot 递归挂载事故
手机使用清理功能后,多个 App 和 SSH 同时失效。这里记录安全模式恢复、目录权限检查、递归挂载来源和启动脚本修改。
把闲置小米手机改成 Ubuntu 服务器
在已 Root 的 Android 13 手机上安装 Ubuntu 24.04,配置 22/8022 两个 SSH 端口、ACC 充电限制和开机脚本。
把手机服务器接入 Tailscale、SSH 和监控
Tailscale 安装在 Android,其他设备通过一个 SSH Host 连接手机,再用 Uptime Kuma 检查 22 端口,用 Beszel 查看 CPU、内存和磁盘。
用 Docker Compose 自建 Headscale,并接入手机和电脑
在 VPS 上部署 Headscale 0.29.3 和 Caddy,创建用户与一次性密钥,再让 Android、iPad、Linux 和 macOS 加入自己的 Tailnet。
把 USB 打印机改成全屋无线打印机:斐讯 N1 + CUPS + brlaser
在斐讯 N1(Armbian/Debian 12)上用 CUPS、Avahi 和源码编译的 brlaser 6.2.8,把只有 USB 口的 Brother HL-2240D 发布成局域网 IPP 打印机,Windows、Android、MacBook 和 Tailscale 设备都能打。
