IT Playbook

What actually happens when you type git push? Why does Kubernetes bring a container back after you kill it? How does a database find one row among millions in a blink? IT Playbook answers questions like these in 30 courses, from your first line of Python to Linux, Docker and Kubernetes, the cloud, networking, security and AI. Each one is written like a good book: one idea at a time, in plain words, nothing skipped. READ IT, OR JUST LISTEN Every lesson is read aloud in a natural voice, sentence by sentence, and the sentence you are hearing lights up on the page. Follow along, or switch on Play in background, put the phone in your pocket and keep learning on a walk, in the car or at the gym: the narration keeps going with the screen off. DON'T JUST READ ABOUT IT. PLAY WITH IT. 338 diagrams in the courses are alive. Kill a pod and watch Kubernetes bring it back. Break one step of a CI pipeline and see where everything stops. Drop numbers into a search tree, let an algorithm find the shortest route, watch scattered points sort themselves into groups. Tap, change a value, and see what happens. Things that take a page to explain click in ten seconds when you can poke them yourself. FLASHCARDS, HANDS-FREE Every course comes with its own flashcards, built from its glossary: almost 7,000 terms in all. Switch on Hands-free and the trainer runs by voice. It reads a definition, you say the term out loud, it tells you whether you got it and moves on. No tapping, no looking at the screen. Do a round while you cook or walk the dog, and the words simply stay with you. A smart schedule brings each card back right before you would forget it. ALSO INSIDE - One beginner course free every month, in full, for anyone with a free account. No credit card needed. - On top of that, the first chapter of all 30 courses is free, so you can try any topic before you decide. - A short quiz after every lesson, with an explanation for every answer, the wrong ones too. - Two voices, the speed you like, and a pause between sentences you can stretch while an idea sinks in. - Whole courses saved for offline, so a flight or a tunnel is no reason to stop. - A daily streak that counts reading and flashcards, because you need both. - Courses re-checked against the official documentation on a regular schedule, so what you learn is still true today. FREE, AND PAID Chapter one of every course is free, and so is every chapter overview and one beginner course each month, in full. An All Courses subscription opens everything: $16.00 a month, or $119.99 a year. Half price for the first year: $8.00 a month for the first twelve months, or $60.00 for the first year. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and it can be managed or cancelled in your Apple Account settings at any time. ONE ACCOUNT EVERYWHERE Your progress, your streak and your flashcard schedule follow you between the iPhone, the iPad, the Mac and the website, because they are the same account and the same data.
