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...

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 ...

Why did that colleague go quiet, that relative bristle, that friend pull away? Most of the time we see only the behaviour and fill in the reason ourselves, often wrongly. This book offers a calm, practical way to look underneath: the everyday needs for control, safety, status and belonging, the information carried by emotions, and the reasons patterns repeat. It also turns the lens on you, covering projection, blame, confirmation and the pull of quick labels, and shows how to check a hunch...

Logging, security, transactions, caching, retries — these concerns cut across every service method in every enterprise application, and implementing them manually produces the same boilerplate in hundreds of places. Aspect-Oriented Programming removes that duplication. This book teaches AOP on both sides of the enterprise divide. It covers AspectJ, the reference implementation whose vocabulary shaped every AOP framework after it. It covers Spring AOP, the proxy-based framework used by most...

Find a Good Therapist is a practical consumer guide to choosing and using therapy, whether you are leaning toward an online therapy service, a local therapist, or both. It is not ...

You will learn to use artificial intelligence tools for research and drafting while keeping your fact...

If you spend the first hour of every month fixing the same export, this book shows you how to do it once. You will learn to think like a pipeline designer: keep the source untouched, turn every fix into a recorded step, and let Power Query replay those steps whenever new data arrives. Clear chapters walk you through connecting to files and folders, trimming and typing messy columns, handling errors and locales, combining a whole folder of workbooks, appending and merging tables, and moving...

A headline says something doubled. An advert promises to cut your risk by half. A poll says most people agree. How do you know what to believe? This book teaches you to read everyday numbers with confidence, no maths background needed. Through simple worked examples built on invented data, you learn what different kinds of average really tell you, how percentages and percentage points differ, why a risk that rises by half may barely matter, how a test that is mostly right can still give mo...
