DRY - Don't repeat yourself

YAGNI - You Aren't Gonna Need It, but have as much as you can out of the box

KISS - Keep it simple, stupid - Kelly Johnson

"Good design is as little design as possible." - Dieter Rams

"Everything should be made as simple as possible, but not simpler." - Albert Einstein

"Complexity is your enemy. Any fool can make something complicated. It is hard to keep things simple." - Richard Branson

"Simple can be harder than complex: You have to work hard to get your thinking clean to make it simple." - Steve Jobs

"I have made this letter longer than usual, only because I have not had the time to make it shorter." - Blaise Pascal

"I have just three things to teach: simplicity, patience, compassion. These three are your greatest treasures." - Lao Tzu

LoD - Law of Demeter or principle of least knowledge

SoC - Separation of Concerns

DI - Dependecy Injection (IoC - Inversion of Control), loosely-coupled

PRG pattern - Post/Redirect/Get

GRASP - General Responsibility Assignment Software Patterns

OOP - Object Oriented Programming

SOLID (object-oriented design) [SolidInPictures](https://lostechies.com/derickbailey/2009/02/11/solid-development-principles-in-motivational-pictures/)

S: SRP - Single Responsibility Principle (a class should have only a single responsibility)

O: OCP - Open/Closed Principle (software entities[classes, modules, functions..] should be open for extension, but closed for modification)

L: LSP - Liskov Substitution Principle (objects should be replaceable with instances of their subtypes without altering the correctness of program)

I: ISP - Interface Segregation Principle (many client-specific interfaces are better than one general-purpose interface)

D: DIP - Dependency Inversion Principle (one should 'Depend upon Abstractions'. Do not depend upon concretions, Dependency injection one method)
