Summary of Clean Architecture by Robert C. Martin

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.

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.

Design rules

Basic steps for hosting on Github

Hey there, apparently people are still using this Gist from 2013! It's out of date! Consult the Github docs.

Steps for Hosting a Website on GitHub

  1. Create a GitHub account on github.com.
  2. Download either [GitHub for Mac][1] or [GitHub for Windows][2], depending on your operating system. Open the app and log in using the account you just created.
  3. (On Mac): After you login, click advanced and make sure that your name and email are correct. Then, click "Install Command Line Tools", just in case you want to start using the command line later in life.
  4. Create a new repository in your GitHub application. Name it your-username.github.io. The name is very important. Note the folder that GitHub is saving the repository to. Make sure the "Push to GitHub?" box is checked.
  5. Move your website's files into the folder that GitHub just created when you made the repository. IMPORTANT: Your homepage HTML file must be called "index.html", and it must exist in the top-level

Node.js TCP client and server example
/*
In the node.js intro tutorial (http://nodejs.org/), they show a basic tcp
server, but for some reason omit a client connecting to it. I added an
example at the bottom.
Save the following server in example.js:
*/
var net = require('net');
