A knowledge base for debugging, tools, and thinking

I write about real troubleshooting, tools, AI, and learning systems that can be revisited, reused, and extended.

Hi, I am Frank Zhang.

This site is mostly about four things: macOS troubleshooting, Vim and productivity tools, AI reflections, and long-term learning methods.

I want it to be more than a place where I simply publish posts. The goal is to build a knowledge base that is easy to search, easy to revisit, and easy to reuse.

If you want something immediately useful, start with the deployment checklist. If you want the explanation version first, go to the posts archive. If you want future updates in your inbox, subscribe.

If you want technical assets that can be reused over time

This site is not just a log of random notes. I care about which troubleshooting steps, tool decisions, deployment lessons, and AI workflows are worth turning into something searchable, reusable, and extensible.

If you care more about long-term reuse than short-lived novelty, start with a free checklist. If you want to understand the site structure first, go straight to the archive or subscribe for updates.
