The Book of PF, 4th Edition Spotted in the Wild

Contributed by Peter N. M. Hansteen on 2026-03-03 from the network fun and games dept.

You may have heard already that a fourth edition of The Book of PF was on the way.

It is now shipping, and when author and undeadly.org co-editor Peter Hansteen finally got his author copies, he wrote a blog post titled The Book of PF, 4th Edition: It's Here, It's Real.

Like Peter says in the article, we would like to encourage readers who can afford it, to support the OpenBSD project.

And there are pictures, of the book and the resident philosopher.
