Python Crash Course: a beginner's book read by someone who is not one Eleven chapters of fundamentals and three projects you have to finish. What I took was not the syntax but the testing chapter and the habit of not leaving a script half done. Craft 16 jun 2026
Practical Statistics for Data Scientists: no number travels alone A reasoned dictionary of statistical concepts for people who write code. It left me a rule about how I present numbers to a client, and one chapter everybody staring at a dashboard should read. Craft 4 jun 2026
Practical Linear Algebra for Data Science: the applied twin The same ground as Strang, with code instead of proofs. Reading two linear algebra books back to back was partly stubbornness; this one gave me something the other did not. Craft 29 may 2026
Odoo 19 Development Cookbook: a good cookbook, and what is missing from it Twenty-three chapters of recipes for the new version. It is the book I keep open while working, and the hole it leaves is exactly the problem I get hired to solve. Architecture Craft 20 may 2026
Discrete Mathematics: count before you promise every combination A university textbook, dry, with four thousand exercises. Reading it without doing them yields little. Of what did stay, two chapters explain things that turn up weekly in business software. Craft 10 may 2026
A 2011 database handbook: normalisation is still the part that does not expire A vocational training handbook from over a decade ago, with PL/SQL examples and typos in its own table of contents. And with two chapters that still explain better than many new books why a field is in the wrong table. Craft 1 may 2026
A Spanish SQL certification manual, and the one chapter that earns it Written against an official syllabus rather than against a problem, and it shows. But the chapter on transactions and concurrency is the one almost nobody reads and the one that explains the most expensive failures. Craft 25 abr 2026
Stillness Is the Key: a visible formula and one idea that survives The third of a trilogy, and the thinnest. The mould is visible by page fifty: historical figure, virtue extracted, closing exhortation. It still changed one of my working habits. Craft 6 abr 2026
Science, Its Method and Its Philosophy: the word diagnosis commits you to something Four short essays by the Argentine physicist and philosopher, read in an afternoon. They left me a standard for what may be called a diagnosis and what is simply a well-dressed opinion. Craft 3 abr 2026
On assertiveness: working alone, you defend yourself with sentences A Spanish classic of popular psychology about saying what you think without attacking or caving in. The theory is the weak part; the concrete techniques are what earns it. Craft Selling 31 mar 2026
Introduction to Linear Algebra: a matrix is not a table of numbers The best known linear algebra course in the world. I read it for a practical reason: to understand what the AI tools I sell are doing underneath. Craft 25 mar 2026
Introduction to Algorithms: I consult it, I do not read it Thirteen hundred pages of pseudocode and proofs. Nobody working on business software needs to read it cover to cover, and nearly everyone needs one of its ideas. Craft 22 mar 2026
