Why I'm learning in public

zsh.fyi is my notebook: the lessons from projects I've shipped and the books that changed how I work.

This is a sample lesson so you can see how long-form writing looks on the site. Replace it with your own, or delete it.

Why write it down

[Explain why you started zsh.fyi: writing helps you think, and sharing saves others the same mistakes.]

The fastest way to learn something is to try to teach it.

What you’ll find here

  • Lessons: what a real project taught me, written so you can use it.
  • The library: the ideas worth keeping from the books I read.
  • Achievements: the projects behind the lessons.

Want to apply this?

Everything here is free to read. If you want help putting an idea into practice with your team, I take on a few hands-on projects each year.
