Tinkering with Ubuntu 26.04

ToDesk on Windows was stuck at 100%, while Ubuntu said it was already connected. I switched to Xfce to get remote access working, then ran into an unresponsive mouse and keyboard, a VMware installation with no password prompt, and missing Ethernet settings. This post follows how I tracked down those problems and filled in the missing desktop components.

One Yuan

Rice paddies give way to factories. A village disappears from the map. Three generations of the Chen family find their lives reaching farther afield. Chen Musheng still hems trousers for one yuan.

SSH Setup Across Systems

Each time I connect machines running Windows, macOS, Ubuntu, or Debian, I end up checking the same things again: how to start the SSH server, whether an administrator or root can log in, and where to put the public key. This guide puts the nine connection directions into one workflow, with a place to start when a connection fails.

Model Confluence

I open-sourced Model Confluence, an AI protocol gateway for Codex, Claude Code, and OpenAI-compatible clients. It converts between Chat Completions, Responses, and Messages, while recording the upstream route, token usage, and latency for every request.

A hands-on study of NeoKylin 7.6

I got an image named zbql7.6_v5u9.iso and, after installing it in VMware, found I knew no password and the system had no network. A "locked" virtual machine sat in front of me, with the console in hand but no way to log in.

I gave up mirror registries for official sources behind a proxy

I used to give every tool its own mirror registry and could never remember which source each one pointed at. Now every tool uses its official source and all traffic goes through a single FlClash proxy — network trouble collapsed from "check each tool's source" to "check the proxy".
