The Leadership Library

Books that shape how I think. Lessons that shape how I lead.

Live at mutaafaziz.com/library: books on engineering leadership, each with a labelled summary of its argument, and my own interpretation, applications, critique, experiments and dated reflections as I write them.

• Everywhere: light, in the manner of Apple Music and Apple Books. A frosted nav, a hero lit by a drifting mesh of the covers' own colours, Recently Added and What's New, every book page washed in its cover, and on phones a tab bar with a Now Reading player.
• On the iPhone Duo: it becomes a book. Closed, you hold one page. Open, the hinge is the gutter of a two-page spread, with the shelf on the left and the book on the right. Unfold mid-chapter and the shelf swings open from the hinge while you keep your place.
• On any foldable: half-open it like a laptop (or a flip phone) and the top screen becomes a stage: the book open on the table, or the portrait's head, while you read and tap on the bottom screen. Every posture is in docs/FOLDABLES.md.

Run it

npm install
npm run build          # content/ → dist/library/
npm run preview        # http://127.0.0.1:4391/library/
npm test               # schema, draft-leak and sanitizer tests
npm run e2e            # Playwright, WebKit + Chromium
npm run stack          # production locally: the site at / and the library at /library/
                       # (needs ../mutaafaziz-site; http://127.0.0.1:8790/)

Add ?duo=open, ?duo=closed or ?duo=auto to any URL to see the book form on a desktop. auto follows the window size, so resizing the window unfolds and folds it. ?duo=off turns it off again for the tab. ?posture=tabletop shows the half-folded layout, and ?fold=debug draws the screen segments the page sees.

Write in it

See docs/CONTENT.md. In short: every block says whose claim it is (Book's argument, My interpretation, My application, My critique), and nothing is public until its visibility is published. Edit, open a PR, merge: it deploys.

Add a book from your phone: open the Add a book form, type a title, ISBN or link, submit. A few minutes later the issue gets a reply with the live link. Comment /remove on it to take the book back out. From a laptop: npm run add -- "Thinking in Systems", then commit.
