Summary of 'Clean code' by Robert C. Martin

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.


General rules

  1. Follow standard conventions.
  2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
  3. Boy scout rule. Leave the campground cleaner than you found it.
  4. Always find root cause. Always look for the root cause of a problem.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Folder Structure

Please note

While this gist has been shared and followed for years, I regret not giving more background. It was originally a gist for the engineering org I was in, not a "general suggestion" for any React app.

Typically I avoid folders altogether. Heck, I even avoid new files. If I can build an app with one 2000 line file I will. New files and folders are a pain.

Trello CSS Guide

Hello, visitors! If you want an updated version of this styleguide in repo form with tons of real-life examples… check out Trellisheets! https://github.com/trello/trellisheets


Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?

Para aprender Ruby e Rails

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.
