About
What is this site
思空栈 (sikong.ren) is Lance's personal site: mostly tech writing, plus a Study Room. In this age of large models, people often say: “AI can already do everything — what's left for us to contribute?” You can argue that code itself has become cheap, but not that AI is a reason to stop thinking. The arrival of agentic tools fixed the one thing that always held me back: plenty of ideas, never the drive to build them. Now the ideas actually get made — and even when all they create is a little delight, the making is still a joy. This site exists mainly to gather up the blog posts I wrote over the years, and to build free, playful teaching projects with AI, for everyone who wants to learn a little about computing. Let's get better together.
