Object-oriented programming is not a single thing. It is a family of ideas that C#, Java, and Python realize in strikingly different ways. This book teaches the paradigm by showing every concept three times — once in each language — so you can move between them without losing your footing. It begins with encapsulation, inheritance, and polymorphism, then moves into abstract classes, interfaces, and the case for composition over inheritance. It covers design patterns, generics, exception hi...

Staring at a grid of empty boxes while someone says 'just use a formula'? You are not behind; most people were never shown how it fits together. This book shows you, patiently, one step at a time. Spreadsheet Formulas for Beginners is a plain-English, step-by-step guide for complete beginners and for people who only know the basics. You will build real examples, a household budget, a sales list, a work schedule and an inventory, and practice at the end of every chapter with answers right b...

You can follow a recipe to the letter. Then one ingredient is missing, the timing is off, or the dish tastes like nothing, and you are stuck with a phone in one hand and a spoon in the other, wondering how other people just know what to do. Cook Without Recipes is the step after the basics. It does not hand you more recipes. It teaches the thinking underneath them: how to taste a pot and name what it needs, how to season without a measuring spoon, how to swap one ingredient for another by ...

Your sleep study is done, your machine runs every night, and the app cheerfully tells you your AHI is under five. So why do you still wake up feeling like you were hit by a truck, reaching for coffee by nine, nodding off at your desk? If a 'good number' and a bad morning are your reality, this book is the missing manual. Still Tired on CPAP is written for the person who is past the first few months and stuck. It is not an onboarding guide to your first weeks with the machine; it starts whe...

A home server runs every hour of the year, so what it draws at idle matters far more than its top speed. This book shows you how to decide what your server must do, compare mini PCs, single-board computers, used office machines and storage boxes, and pick processor, drives and power supply with idle watts in mind. You will measure real consumption at the wall, build a baseline, and tune firmware and Linux settings one safe step at a time. Chapters on cooling, noise, drive spin-down, sleep ...

Most food waste is decided long before anything reaches the bin: in the shop, in the fridge drawer, in the pot that made too much. This book gives you a practical system for cutting it down without turning cooking into a chore. You will audit what you really throw away, build a flexible shopping plan, store food so it lasts longer, and learn what date labels and food-safety limits actually mean. Then you put leftovers and scraps to work with recipes that give quantities, times and numbered...

The pipeline is green, every job reports success, and the number on the dashboard is still wrong. If you build or maintain tables that other people trust, this book shows you how to catch the problems that do not announce themselves. You will profile a table before writing rules, find exact and near duplicates, tell harmless gaps from harmful ones, write layered rules for invalid records, spot schema changes before they spread, and expose silent errors with volume, freshness and reconcilia...

Every year, millions of buyers walk onto a lot or into a stranger's driveway and hand over thousands of dollars for a machine they cannot properly evaluate. Buy a Used Car Without Getting Burned closes the information gap between the person selling the car and the person buying it. Written for the ordinary adult with a smartphone and an afternoon, it walks the reader through a repeatable, gate-by-gate process: setting a real four-part budget, reading listing photos like a detective, sendin...

Your jaw is tight before the alarm even goes off, and by afternoon the ache has moved to your temple, ear, or neck, after a night guard and a bite adjustment that didn't fix it. This book argues chronic jaw pain is usually a muscle-and-nerve problem fed by stress, not a damaged hinge, and builds a plan around that: catching daytime clenching early, using a night guard for what it can realistically do, taking load off a neck quietly sharing the work, and knowing which professional treatment...

Your team keeps copying data from one tool into another, and every fix you hear about starts with the words "just use the API". This book makes that sentence usable. You will learn how a request and a response are built, how to read status codes and JSON, how services check who you are with keys and tokens, and how to fetch thousands of records without missing a single page. Then you will handle rate limits, retries and webhooks, and finish with a complete, scheduled integration written as...

Standing in the aisle with a box in each hand, the numbers on the back rarely line up the way you need them to. This guide turns the label into something you can read in about a minute. You will learn what a serving really is and how to scale it to your own bowl, how salt and sodium relate, where added sugars hide behind unfamiliar names, how to judge fibre by its source, and how to read an ingredient list as a ranking. It also shows how to test the claims on the front of the pack and the ...

A clear, grounded guide to what the Bible actually says about the last days — written for people who are tired of the hype. Drawing on Matthew 24, Daniel, Revelation, and the letters of Paul, No Time Like The End Times walks through the Antichrist, the rapture, the tribulation, and the return of Christ without speculation or date-setting. It lays out the major interpretive views fairly, marks the difference between what Scripture settles and what it leaves open, and keeps the center where ...
