Summary of book "Clean Architecture" by Robert C. Martin

Uncle Bob, the well known author of Clean Code, is coming back to us with a new book called Clean Architecture which wants to take a larger view on how to create software.

Even if Clean Code is one of the major book around OOP and code design (mainly by presenting the SOLID principles), I was not totally impressed by the book.

Clean Architecture leaves me with the same feeling, even if it's pushing the development world to do better, has some good stories and present robust principles to build software.

The book is build around 34 chapters organised in chapters.

/**
 *  When manually subscribing to an observable in a view component, developers are traditionally required
 *  to unsubscribe during ngOnDestroy. This utility method auto-configures and manages that relationship
 *  by watching the DOM with a MutationObserver and internally using the takeUntil RxJS operator.
 *
 *  Angular 7 has stricter enforcements and throws errors with monkey-patching of view component life-cycle methods.
 *  Here is an updated version that uses MutationObserver to accomplish the  same goal.

I bundled these up into groups and wrote some thoughts about why I ask them!

If these helped you, I'd love to hear about it!! I'm on twitter @vcarl_ or send me an email [email protected]

• How long will it take to deploy my first change? To become productive? To understand the codebase?
• What kind of equipment will I be provided? Will the company pay/reimburse me if I want something specific?

Dependency Injection in Functional Programming

There exist several DI frameworks / libraries in the Scala ecosystem. But the more functional code you write the more you'll realize there's no need to use any of them.

A few of the most claimed benefits are the following:

• Dependency Injection.
• Life cycle management.
• Dependency graph rewriting.

Agile Contract Guide

This document is a guide to writing agile contracts. Unlike traditional contracts, an agile contract does not specify individual tasks to be completed by the Contractor. Rather, an agile contract specifies how the Client and Contractor interact, and how the Contractor is paid. The Deliverable Work performed for the contract is determined through an ongoing collaboration between the Client and the Contractor.

Agile contracts require a great deal of trust from both the Client and the Contractor. This trust is fostered through tight feedback cycles and well-defined responsibilities that both parties can expect from each other. More so than traditional contracts, an agile contract requires active participation from the Client.

Monolithic Components, Composable Components

Introduction

Building reusable UI components is a non trivial task, as we need to anticipate a number of things when planing for reuseability. On the one end of the spectrum we want to enable customization and on the other side we want to avoid developers doing the wrong thing, like breaking the component or displaying invalid states.

To get a better understanding of what we need to think about and consider upfront, we will build a non-trivial UI component, that displays tags. Our Tags component will take care of managing and displaying tags.

The following examples are all built with Tachyons and React, but these ideas apply to any UI component and any general styling approach.

Coisas que eu não sabia que eu não sabia sobre testes por Hugo Baraúna

• Por que fazer testes?
  • saber se o software está funcionando de maneira automatizada
    • não elimina os testes exploratórios feito de forma manual
  • manter custos de desenvolvimento em níveis saudáveis
  • ajuda na qualidade interna do código (design e arquitetura do código)
• Como avaliar a qualidade dos testes (se estão bem feitos)?
  • corretude - se o teste não está gerando um falso positivo
• adequação do tipo de teste - se o teste é o mais adequado para a situação
