É difícil falar de Ruby sem mencionar seu framework web mais famoso, Ruby on Rails. Mas não adianta muito encarar o framework sem um prévio estudo da linguagem (o que de fato já observei acontecer inúmeras vezes). Esse post tem como intuito auxiliar na aprendizagem tanto da linguagem como do framework, para evitar que erros comuns como esse tornem a utilização de ambos um desastre.

Ruby

Ruby é uma linguagem de programação que apareceu para o mundo em 1995, criada por Yukihiro "Matz" Matsumoto. Tem como características o fato de ser uma linguagem de uso geral, com tipagem dinâmica e forte, orientada a objetos e que incorpora diversos paradigmas de programação, como o funcional e o imperativo.

Converting a Word Document to Markdown in Two Moves

The Problem

A lot of important government documents are created and saved in Microsoft Word (*.docx). But Microsoft Word is a proprietary format, and it's not really useful for presenting documents on the web. So, I wanted to find a way to convert a .docx file into markdown.

The Solution

As it turns out, there are several open-source tools that allow for conversion between file types. Pandoc is one of them, and it's powerful. In fact, pandoc's website says "If you need to convert files from one markup format into another, pandoc is your swiss-army knife." But, although pandoc can convert from markdown into .docx, it doesn't work in the other direction.

# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName

Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

• Single Responsibility Principle: a class should have only a single responsibility
• Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
• Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
• Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.
