contributions welcome HitCount

Why? 🤷‍♀️

Setting up a software engineering computer can take a long time. ⏳
We need to streamline the process so that we can start work as quickly as possible. 🏁
This doc outlines all the steps we take to setup our typical system. 💻

If you find it helpful, please the repo to let us know. Thanks.

What?

This repo contains the tools we use.

If you have a tool or setup step you think we should include/use, please open an issue to let us know! 🙏

Note: The intention is not to include every fancy script, tip and trick under the sun, this is about basic setup and getting going when you're new and already have a steep learning curve!

Who?

  1. People who are new to software engineering.
    Particularly people who have learnt online using inbuilt browser-based editors and tools (often the case in online courses) and have not set up their own environment before.

  2. People @dwyl who have just got a new computer and need to set it up as quickly as possible so they can get work done.

Note: @dwyl we use a specific technology stack that includes PostgreSQL and Elixir Installing most of this software is optional, but it does make you more effective so we highly recommend it.
This repo includes some recommendations of things we favour and use @dwyl.

How?

Ensure you have a decent internet connection when setting up your machine, several gigabytes will be downloaded.

Note: if you lack a good internet connection, simply skip downloading the browser(s) and other larger Apps. But we are assuming that if you are reading this, you have access to decent bandwidth to be a Developer/Engineer. Please, share your experience if not! We are very curious to hear from bandwidth-constrained people! 🙏 We would like to formulate a "Low Cost / Bandwidth" version of this doc for use on a Raspberry Pi or other lower cost computer. We could even create a pre-built SD card with everything required. 💭

Web Browsers

The reason the word "browsers" is plural is simple: having multiple web browsers allows you to segment your use of each one for a specific purpose. e.g:

  1. Safari - the default browser on Mac. Keep it "stock" (no plugins/themes), use it for UAT testing web apps to know what they will look & feel like to people who own Macs but don't bother to download a different browser. Safari is good for personal things too as it has good privacy and speed.
  2. Google Chrome: google.com/chrome The baseline for web development. Great Dev Tools, profiling etc.
  3. Firefox: mozilla.org/firefox We use Firefox for testing our Web apps because it has the best support for Web Standards. It's fast, free and surfaces potential bugs in our code better than other browsers.

In addition to these there are many other browsers you can install/use, for example:

  1. Brave: brave.com/download Based on Chrome but with built-in ad-blocker. Use Brave to watch YouTube lectures/tutorials without Ads.
  2. Google Chrome Canary: google.com/chrome/canary/ Chrome but with all latest features.
  3. Firefox Developer Edition: mozilla.org/firefox/developer/ Useful for debugging and testing web apps. We have it installed as a backup browser for when we need to test multiple clients concurrently.
  4. Microsoft Edge: microsoft.com/edge Based on Google Chrome but with a few Microsoft enhancements.

As noted in #9 we have several web browsers installed and use them for specific purposes:

Given that Microsoft now owns GitHub and can read everything we do on the platform (both public and private...) we use Edge for all our GitHub interactions (e.g. reading notifications, responding to issues/questions, etc.) Edge is our "GitHub browser".

You are free to come up with your own system, but having multiple browsers and segmenting your use can mean you have fewer tabs in your "work" browser and can easily separate any personal stuff.

Git + GitHub

We use Git and Github exclusively for our version control and to share our work with the world.
Understanding the difference between the two is also helpful.

If you don't already have a GitHub account, sign up for one: github.com/join

2 Factor Authentication (2FA)

2FA protects your Github account and also any organisations you are a member of from malicious intent.

Next steps? If you want to contribute to dwyl projects, you can easily do so without knowing any of our
tech stack. Simply use the App and open issues whenever you have questions!

Basic Git setup

Follow the official set up Git guide to get it working on your computer.

Setup ssh authentication as it is more secure and means you _won't have to type in your password every time you push to GitHub.

Note: This also means that when you clone a repo, you'll need to use the SSH clone URL (thanks @tsop14 for the screenshot!)

Learn how to use Git + GitHub

There are many resources online: start-here#git

Although Git has a desktop client, we recommend that you learn to use it on the command line. This is much faster in the long run and will serve you well when you need to understand how things work.

Mac 🍏

This section is specific to Mac computers. Skip it if you are using Linux or Windows.

PostgresApp

We find PostgresApp to be the easiest way to manage PostgreSQL on Mac. It gives us a basic graphical user interface (GUI) and menu bar icon that informs us of the status of the DB.

Download: https://postgresapp.com/

PGAdmin

Postgres https://www.pgadmin.org/

Rectangle

Rectangle is window manager/tiler for Mac, it gives you keyboard shortcuts for moving/organising your Apps/Windows: rectangleapp.com

image

Note: Rectangle will request/require "accessibility" permissions to control your windows. This is normal.

Keyboard Shortcuts

Using Rectangle is fastest via the keyboard shortcuts:

You can add your own shortcuts if you prefer. We haven't found the need to yet.

Homebrew

If you are setting up a Mac, you will need to install homebrew brew.sh, the package manager that will download and manage several other open source software packages.

Install with the following command in your terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

iTerm

The default terminal emulator on Mac is OK for basic tasks...
We find that iTerm is considerably better UX. e.g: iTerm allows screen splitting:

iterm-screen-splitting

As with Web Browsers, it doesn't hurt to have more than one Terminal on your Mac.

Themes

There are many themes which you may have heard of (like Oh My Zsh) that aim to add some functionality and shortcuts to your terminal. We don't recommend you use any terminal themes when you're starting out because they are a distraction from the content/code you are crafting.

However, once you know what you're doing in the terminal, you can consider enhancing your terminal with themes. There are many to choose from: iterm2colorschemes.com


Everyone

The following applies to all people regardless of their operating system (Linux, Mac & Windows)

Text Editor

It's your choice which text editor you use, but you will inevitably need (at least) one editor. At the time of writing, @dwyl we use Atom (Open Source, Electron/NodeJS based editor).

There are a wide range of text editors and integrated development environment (IDEs) available.

We tend to use:

  • Atom: https://atom.io Open Source and has many plugins for language and framework support. Download and install it even if you only use it as a "backup" editor. VSCodium https://vscodium.com the Open Source version of VS Code. All Plugins work as expected but no Tracking from Microsoft.
  • VS Code: https://code.visualstudio.com as a backup or read-only viewer when we are working on multiple projects concurrently.
  • Sublime Text: sublimetext.com - fast and free-ish (you will be reminded to purchase a license ... but the license is perpetual not annual!)

Basic text editor setup

Set up soft tabs (indentation)
You can usually set this up in the Preferences or Settings of your favourite text editor so you never have to think about it again (example below for Atom):

atom-soft-tab-preferences-menu

  • Set up a guide (or line) to show on your page at the 80 character mark so you know when you go past 80 characters (or columns) on a single line
    • Useful for readability, particularly in code snippets where you would otherwise end up with a scroll bar
    • You should also be able to set this up in your favourite text editor's Preferences (example below again on Atom editor - note, I also like to set up my editor to soft wrap at this line length so I can read other people's code more easily)

How to connect Github to Atom step-by-step

First of all you need to create a Github Account and then create a new repository, name it as you wish.

Now you have a link to your repository and instructions to how to create a new repository in the command line.
Now go to Atom and press cmd+SHIFT+P and you enter Github:clone and then paste your link.

A couple a seconds later you have your repository on the left side of the screen.

Screen Shot 2020-01-12 at 22 42 59

The next thing to do is authorize Github for atom so go to github.atom.io/login.
Just make the login with your information and copy the GitHub token after having your GitHub token copied go to Atom to the GitHub tab in the right lower corner and you will see a login just paste your token there and now you are connected to GitHub.

So now if you create a file and edit with your own text you can upload the file to GitHub by going to the git tab and Stage the changes in your file you have to give a commit message the first time you edit the file. Then click on Commit to master.

Now click on master and then on new branch and call it whatever you want then click on publish. You will have to enter your credentials again to validate those changes.

If you go on your created repository and press F5 you should see those changes.

Install at least a linter in your editor.

Our most used text editor keyboard shortcuts

Each person's most used shortcuts will vary of course, but here are some of the things we suggest learn the keyboard shortcuts for:

  • Select the current word (usually cmd + D)
  • Delete current line (usually ctrl + shift + K)
  • Indenting a line or a whole block of code at once
  • Column editing
  • Moving a line or block of code up and down the page
  • Changing the syntax highlighting when required
  • Toggle between the different views (e.g. hide/show the file tree view to gain more screen real estate)

Linux 🐧

At present several members of our team/community use a Linux distro as their primary operating system.

If this is you, please help: dev-setup/issues/49 🙏

Ideally we would make the instructions RaspberryPi-friendly.
