Quick Intro

Object Orientation is not the only way
Functional Programming need not be complex or mathematical
The bases of programming are not assignments, if statements and loops
Concurrency does not need locks, semaphores, monitors and the like
Processes are not necessarily expensive resources
Metaprogramming is not just something tacked onto a language
Even if it is work, programming should be fun

Learning

Vim Genius - a timed flashcard game for regular vim commands
Open Vim - interactive vim to try out - don't need to install vim to start practicing it
Vim Adventures - a simple game to practice basic navigation keys(hjkl) and get rid of arrows
Vim Casts - free screen casts about vim

Reference

Vi / Vim cheat sheet - keys and simple commands

Introduction

Developers like new things and Vim is definitely a totally new and different thing if you are used to editors like Sublime, Atom, Text Mate or VSCode. Seems difficult because is new. Everything that is new for us tends to be difficult. So, let's start with a plan: keep it short, keep it simple, keep it going. It means that the plan is to constantly improve vim knowledge by getting new tips, using it a lot and then master it. Will try to follow that with this Vim series.

Roadmap:

1 - Syntax - pipe operator / collections 2 - Pattern Matching + pin operator(^)

Estimation

Understand the problem as much as you can(if not, ask someone for clarification)

1.1. Break the task as much as possible in order to have an accurate estimation

1.2. Think about edge cases(this is tricky) but it's a good exercise to try to decrease scope

Planning

Introduction

React is a js library(not a framework) to build interfaces. It is declarative, we can describe user interfaces by telling React what we want, not telling how to do it.

3 Design Concepts

Component

It is a simple function, receive input and returns output. The input can be props or state.

Intro

A leitura deste livro tem como fim o aperfeiçoamento profissional e mudança no modo de enxergar o desenvolvimento. Algumas informações são essenciais para isto, como: boas práticas sempre levam a um bom design de código.

Dicas

Single Responsability: Perguntar para a classe sobre seu próprio método, ex.: Carro qual a sua cor ? Isto ajuda a definir se um método faz sentido para a aquela classe, o que ajuda a definir que uma classe deve fazer apenas o que é de sua responsabilidade. Se perguntarmos: Carro qual é a capacidade do seu tanque ? talvez até faça sentido, mas

	class Game
	def self.play(move1, move2)
	return :tie if move1.class == move2.class

	move1.wins_against?(move2)
	end
	end

	class Base
	def wins_against?(other_move)
