But if code isn't clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn't have to be that way. Noted software expert Robert C. Martin presents a revolutionary paradigm with Clean Code: A Handbook of Agile Software Craftsmanship . Martin has teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code on the fly into a book that will instill within you the values of a software craftsman and make you a better programmer but only if you work at it. What kind of work will you be doing? You'll be reading code - lots of code. And you will be challenged to think about what's right about that code, and what's wrong with it. More importantly, you will be challenged to reassess your professional values and your commitment to your craft. Clean Code is divided into three parts. The first describes the principles, patterns, and practices of writing clean code. The second part consists of several case studies of increasing complexity. Each case study is an exercise in cleaning up code - of transforming a code base that has some problems into one that is sound and efficient. The third part is the payoff: a single chapter containing a list of heuristics and "smells" gathered while creating the case studies. The result is a knowledge base that describes the way we think when we write, read, and clean code. Readers will come away from this book understanding ‣ How to tell the difference between good and bad code‣ How to write good code and how to transform bad code into good code‣ How to create good names, good functions, good objects, and good classes‣ How to format code for maximum readability ‣ How to implement complete error handling without obscuring code logic ‣ How to unit test and practice test-driven development This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.

    * * *Download for FREE on Kindle Unlimited + Free BONUS Inside!* * *From the ~Personality Disorders and Mental Illnesses~ collection and the award winning writer, Paul Sorensen, comes a masterful explanation into the mind of a sociopath! "An excellent depiction of the modern day sociopath!" - Alex Lemmings, Book CritiqueThink of sociopaths, and what’s the first thing that enters your mind? The soulless murderer, lurking in the shadows? Or perhaps you think of the ruthless business man turned hardened criminal, a modern day depiction in recent movies and media.You’d probably be surprised to know that you’ve met a sociopath already, at least one. Are they your classmate, colleague, friend, or even lover? The thing about sociopaths that so few realize is that they are chameleons, masters at blending in. Unless you know them intimately, you will have no idea what’s going on behind the charming façade.In the real world, sociopaths are far more likely to lie to family members, steal from workplaces, cheat on their partners, abuse drugs, and commit fraud, than they ever are to murder someone.Although not all actions by a sociopath are criminal, many are what society considers immoral, and you remain unaware of the sociopaths in your own life at your peril. In this book you will learn what a true sociopath is like, how to recognize them, and how to deal with them – especially if they cannot be avoided. I also discuss how to help yourself heal after you come out the other side.Is there a cure, or even any hope for sociopaths? The short answer is ‘we don’t know’, but there’s a lot more to it than that, and forewarned is forearmed. Don’t let yourself become the next to be manipulated, lied to, or even assaulted or have your life destroyed by the sociopath you know.Topics of Discussion ✓ What is Sociopathy? ✓ Sociopathic Personalities ✓ How to Recognize a Sociopath ✓ Surviving a Sociopath ✓ Clinical Sociopathy ✓ The Cause of Sociopathy ✓ Is there a Cure? ✓ BONUS!

    This authoritative book scrapes away these bad features to reveal a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole--a subset you can use to create truly extensible and efficient code.Considered the JavaScript expert by many people in the development community, author Douglas Crockford identifies the abundance of good ideas that make JavaScript an outstanding object-oriented programming language-ideas such as functions, loose typing, dynamic objects, and an expressive object literal notation. Unfortunately, these good ideas are mixed in with bad and downright awful ideas, like a programming model based on global variables.When Java applets failed, JavaScript became the language of the Web by default, making its popularity almost completely independent of its qualities as a programming language. In JavaScript: The Good Parts, Crockford finally digs through the steaming pile of good intentions and blunders to give you a detailed look at all the genuinely elegant parts of JavaScript, including:SyntaxObjectsFunctionsInheritanceArraysRegular expressionsMethodsStyleBeautiful featuresThe real beauty? As you move ahead with the subset of JavaScript that this book presents, you'll also sidestep the need to unlearn all the bad parts. Of course, if you want to find out more about the bad parts and how to use them badly, simply consult any other JavaScript book.With JavaScript: The Good Parts, you'll discover a beautiful, elegant, lightweight and highly expressive language that lets you create effective code, whether you're managing object libraries or just trying to get Ajax to run fast. If you develop sites or applications for the Web, this book is an absolute must.

The author has been a professional programmer for seventeen years and draws heavily (and candidly) on actual coding problems and practices based on years of experience at Microsoft.

    Inside the house, they were confronted with a scene from a nightmare.The thick black smoke was rising from a series of wood-burning stoves throughout the property that were stocked with human remains. In the basement, they discovered a furnace with larger body parts and a pit filled with quicklime and decay. There were suitcases full of the deceased’s belongings, and in the other rooms, they came upon something like a factory line of bodies. This was not mere murder – it was methodical processing of corpses.The homeowner was Dr. Marcel Petiot, an admired and charismatic physician. When questioned, Dr. Petiot claimed that he was a part of the Resistance and the bodies they discovered belonged to Nazi collaborators that he killed for the cause. The French Police, resentful of Nazi occupation and confused by a rational alternative, allowed him to leave.Was the respected Doctor a clandestine hero fighting for national liberty or a deviant using dire domestic circumstances to his advantage? One thing is for certain, the Police and the Nazis both wanted to get their hands on Dr. Marcel Petiot to find out the truth.Doctor Satan is a chilling account of Dr. Marcel Petiot and one of the most disturbing true crime stories in French history. Ryan Green’s riveting narrative draws the reader into the real-live horror experienced by the victims and has all the elements of a classic thriller.CAUTION: This book contains descriptive accounts of torture, abuse and violence. If you are especially sensitive to this material, it might be advisable not to read any further.
