Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional, and may contain IDs of the task / user story we are changing the code for (e.g. SELL-123)

Example

xpepper

interface GameRulesInputBoundary
  void moveSouth()
end

interface GameRulesOutputBoundary
  void moveSouthSucceed()
end

class GameRules implements GameRulesInputBoundary
  def init(GameRulesOutputBoundary outputBoundary)

Clean-Architecture

Notes, comments and errata on Robert C. Martin's Clean Architecture

Reading the book

The book has 34 chapters, with a maximum of 22 pages (chapter 14). Even while involved as a programmer in a project, it should be possible to read one chapter per day, so you can finish the book in about 2 months.

Errata

Page 15, just before subchapter "The greater value".

What is a Design Pattern?

Every Software Engineer certainly must have to deal with change. Change is a constant in Software Design: adding feature, changing of requirement or bug fixing.

What is a design pattern? In simplest way I can say, it is a general solution for common problems in Software Development. The purpose of design patterns is to help structure your code so it will be flexible and resilient when its changed.

There are 23 common design patterns that are being used by programmers around the world. In this chapter I am going to describe the Observer Pattern.

Before to start

In JavaScript there is NO concept of Class.

Everything is an Object.

Inheritance between objects is achieved with a mechanism known as Prototypal Inheritance.

We can create Objects and then link them together OLOO (Objects-Linked-to-Other-Objects).
