The short answer to "how do you actually make these books?" — moved off the homepage and onto its own page so it can say its piece without crowding everything else.

How These Books Actually Get Written

Our team has built things with computers since the early 1980s — long enough to know a genuine shift when we see one, and to have picked up more than one subject along the way. Linux is where that experience landed.

These books have a co-author: an AI we work with directly, not around. It drafts, we steer and check every word and every command in here gets run before it ships. What actually happens between those things stays ours for now — some things are worth more unexplained than explained.

So to summarize, everything gets checked twice or sometimes more… and the one number we've published from that process was small enough to surprise us.

Curious how it really works? Ask. There may be more of this to come.

Behind The Number

How That Number Actually Got Here

The ring above is a live figure we recompute and act on, not a badge set once and forgotten. Here's the actual path it took to get here.

0.043‰
First time we measured it and put a number on the page.
Sep 6, 2026
0.896‰
We widened what the checklist actually looks for. The number moved because the bar went up.
Sep 7, 2026
0.000‰
Went through everything the wider checklist had flagged, one item at a time, until none were left.

A new book joined what we track. Its own checklist hits moved the number for the first time since it hit zero.
How this actually works, roughly →

We track a growing checklist of specific patterns that tend to give away AI-written prose. Each one gets flagged automatically, then confirmed by hand, before it's called "fixed." The number above is whatever that checklist currently finds, recomputed on a regular basis.

It can go back up. New chapters get written, and the checklist itself keeps growing as we learn what to look for next. When it moves, we treat that as real data — the same numbers we use ourselves to decide what to fix next.

The exact checklist stays ours. The honest summary: it's more checking, and more rewriting, than a single clean number tends to suggest.
