Click on the "Share" button, then on "GitHub (Sign in using GitHub account)".
A popup appears asking you to sign in with GitHub: click on "Allow".
You are redirected to a GitHub page in you browser asking you to authorize Visual Studio Code: click on "Continue" then "Authorize github".
VS Code may display additional pop-ups: close them by clicking "OK".

That's it, you're good to go!

Command line tools

Zsh & Git

Instead of using the default bash shell, we will use zsh.

We will also use git, a command line software used for version control.

Let's install them, along with other useful tools:

Open an Ubuntu terminal
Copy and paste the following commands:

sudo apt update

sudo apt install -y curl git imagemagick jq unzip vim zsh tree

These commands will ask for your password: type it in.

⚠️ When you type your password, nothing will show up on the screen, that's normal. This is a security feature to mask not only your password as a whole but also its length. Just type in your password and when you're done, press Enter.

GitHub CLI installation

Let's now install GitHub official CLI (Command Line Interface). It's a software used to interact with your GitHub account via the command line.

In your terminal, copy-paste the following commands and type in your password if asked:

sudo apt remove -y gitsome # gh command can conflict with gitsome if already installed
curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null

sudo apt update

gh --version

✔️ If you see gh version X.Y.Z (YYYY-MM-DD), you're good to go 👍

❌ Otherwise, please contact a teacher

Oh-my-zsh

Let's install the zsh plugin Oh My Zsh.

In a terminal execute the following command:

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

If asked "Do you want to change your default shell to zsh?", press Y

At the end your terminal should look like this:

✔️ If it does, you can continue 👍

❌ Otherwise, please ask for a teacher

Linking your default browser to Ubuntu

To be sure that you can interact with your browser installed on Windows from your Ubuntu terminal, we need to set it as your default browser there.

⚠️ You need to execute at least one of the following commands below:

Google Chrome as your default browser

Run the command:

  ls /mnt/c/Program\ Files\ \(x86\)/Google/Chrome/Application/chrome.exe

Did you get an error like ls: cannot access...?

Yes, I had an error

Run the following commands:

  echo "export BROWSER=\"/mnt/c/Program Files/Google/Chrome/Application/chrome.exe\"" >> ~/.zshrc
  echo "export GH_BROWSER=\"'/mnt/c/Program Files/Google/Chrome/Application/chrome.exe'\"" >> ~/.zshrc

No, everything was fine

Run the following commands:

  echo "export BROWSER=\"/mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe\"" >> ~/.zshrc
  echo "export GH_BROWSER=\"'/mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe'\"" >> ~/.zshrc

Mozilla Firefox as your default browser

Run the command:

  ls /mnt/c/Program\ Files\ \(x86\)/Mozilla\ Firefox/firefox.exe

Did you get an error like ls: cannot access...?

Yes, I had an error

Run the following commands:

  echo "export BROWSER=\"/mnt/c/Program Files/Mozilla Firefox/firefox.exe\"" >> ~/.zshrc
  echo "export GH_BROWSER=\"'/mnt/c/Program Files/Mozilla Firefox/firefox.exe'\"" >> ~/.zshrc

  echo "export GH_BROWSER=\"'/mnt/c/Program Files (x86)/Microsoft/Edge/Application/msedge.exe'\"" >> ~/.zshrc

Restart your terminal.

Then please make sure that the following command returns "Browser defined 👌":

[ -z "$BROWSER" ] && echo "ERROR: please define a BROWSER environment variable ⚠️" || echo "Browser defined 👌"

If it does not,

✔️ If you got this message, you can continue 👍

❌ If not, choose a browser in the list above and execute the corresponding command. Then don't forget to reset your terminal:

exec zsh

Do not hesitate to contact a teacher.

GitHub CLI

CLI is the acronym of Command-line Interface.

In this section, we will use GitHub CLI to interact with GitHub directly from the terminal.

It should already be installed on your computer from the previous commands.

First in order to login, copy-paste the following command in your terminal:

⚠️ DO NOT edit the email

gh auth login -s 'user:email' -w

gh will ask you few questions:

What is your preferred protocol for Git operations? With the arrows, choose SSH and press Enter. SSH is a protocol to log in using SSH keys instead of the well known username/password pair.

Generate a new SSH key to add to your GitHub account? Press Enter to ask gh to generate the SSH keys for you.

If you already have SSH keys, you will see instead Upload your SSH public key to your GitHub account? With the arrows, select your public key file path and press Enter.

Enter a passphrase for your new SSH key (Optional). Type something you want and that you'll remember. It's a password to protect your private key stored on your hard drive. Then press Enter.

Title for your SSH key. You can leave it at the proposed "GitHub CLI", press Enter.

You will then get the following output:

! First copy your one-time code: 0EF9-D015
- Press Enter to open github.com in your browser...

Select and copy the code (0EF9-D015 in the example), then press Enter.

Your browser will open and ask you to authorize GitHub CLI to use your GitHub account. Accept and wait a bit.

Come back to the terminal, press Enter again, and that's it.

To check that you are properly connected, type:

gh auth status

✔️ If you get Logged in to github.com as <YOUR USERNAME> , then all good 👍

❌ If not, contact a teacher.

Dotfiles (Standard configuration)

Hackers love to refine and polish their shell and tools.

We'll start with a great default configuration provided by Le Wagon: lewagon/dotfiles.

As your configuration is personal, you need your own repository storing it. So you will fork Le Wagon repository.

Forking means that you will create a new repo in your own GitHub account $GITHUB_USERNAME/dotfiles, identical to the original Le Wagon one that you will be able to modify at will.

Open your terminal and set a variable for your GitHub username:

export GITHUB_USERNAME=`gh api user | jq -r '.login'`

echo $GITHUB_USERNAME

✔️ You should see your GitHub username printed.

❌ If not, stop here and ask for help. There may be a problem with the previous step (gh auth).

⚠️ Please note that this variable is only set for the time your terminal is open. If you close it before or during the next steps, you need to set it again with the two steps above!

Time to fork the repo and clone it on your computer:

mkdir -p ~/code/$GITHUB_USERNAME && cd $_

gh repo fork lewagon/dotfiles --clone

Dotfiles installer

Run the dotfiles installer:

cd ~/code/$GITHUB_USERNAME/dotfiles

zsh install.sh

Check the emails registered with your GitHub Account. You'll need to pick one at the next step:

gh api user/emails | jq -r '.[].email'

✔️ If you see the list of your registered emails, you can proceed 👍

❌ If not, please reauthenticate to GitHub before running this command ☝️ again.

git installer

Run the git installer:

cd ~/code/$GITHUB_USERNAME/dotfiles && zsh git_setup.sh

☝️ This will prompt you for your name (FirstName LastName) and your email.

⚠️ You need to put one of the emails listed above thanks to the previous gh api ... command. If you don't do that, Kitt won't be able to track your progress. 💡 Select the @users.noreply.github.com address if you don't want your email to appear in public repositories you may contribute to.

Please now reset your terminal by running:

exec zsh

Disable SSH passphrase prompt

You don't want to be asked for your passphrase every time you communicate with a distant repository. So, you need to add the plugin ssh-agent to oh my zsh:

First, open the .zshrc file:

code ~/.zshrc

Then:

Spot the line starting with plugins=
Add ssh-agent at the end of the plugins list

✔️ Save the .zshrc file with Ctrl + S and close your text editor.

rbenv

Let's install rbenv, a software to install and manage ruby environments.

First, we need to clean up any previous Ruby installation you might have:

rvm implode && sudo rm -rf ~/.rvm
# If you got "zsh: command not found: rvm", carry on.
# It means `rvm` is not on your computer, that's what we want!
rm -rf ~/.rbenv

Then in the terminal, run:

sudo apt install -y build-essential tklib zlib1g-dev libssl-dev libffi-dev libxml2 libxml2-dev libxslt1-dev libreadline-dev libyaml-dev

git clone https://github.com/rbenv/rbenv.git ~/.rbenv

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build

exec zsh

Ruby

Installation

Now, you are ready to install the latest ruby version and set it as the default version.

Run this command, it will take a while (5-10 minutes)

rbenv install 3.3.5

Once the ruby installation is done, run this command to tell the system to use the 3.3.5 version by default.

rbenv global 3.3.5

Reset your terminal and check your Ruby version:

exec zsh

Then run:

ruby -v

✔️ If you see something starting with ruby 3.3.5 then you can proceed 👍

❌ If not, ask a teacher

Installing some gems

If you are in China 🇨🇳 click here

⚠️ If you are in China, you should update the way we'll install gem with the following commands.

# China only!
gem sources --remove https://rubygems.org/
gem sources -a https://gems.ruby-china.com/
gem sources -l
# *** CURRENT SOURCES ***
# https://gems.ruby-china.com/
# Ruby-china.com must be in the list now

Everyone, in China or not, continue here to install gems.

In the ruby world, we call external libraries gems: they are pieces of ruby code that you can download and execute on your computer. Let's install some!

First, we'll update bundler, which is what lets us install gems:

gem update bundler

In your terminal, copy-paste the following command:

gem install colored faker http pry-byebug rake rails:7.1.3.4 rest-client rspec rubocop-performance sqlite3:1.7.3 activerecord:7.1.3.2

✔️ If you get xx gems installed, then all good 👍

❌ If you encounter the following error:

ERROR: While executing gem ... (TypeError)
incompatible marshal file format (can't be read)
format version 4.8 required; 60.33 given

Run the following command:

rm -rf ~/.gemrc

Rerun the command to install the gems.

⚠️ NEVER install a gem with sudo gem install! Even if you stumble upon a Stackoverflow answer (or the terminal) telling you to do so.

Node.js

Node.js is a JavaScript runtime to execute JavaScript code in the terminal. Let's install it with nvm, a version manager for Node.js.

In a terminal, execute the following commands:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | zsh

exec zsh

Then run the following command:

nvm -v

You should see a version. If not, ask a teacher.

Now let's install node:

nvm install 20.17.0

When the installation is finished, run:

node -v

If you see v20.17.0, the installation succeeded ✔️ You can then run:

nvm cache clear

❌ If not, contact a teacher

yarn

yarn is a package manager to install JavaScript libraries. Let's install it:

In a terminal, run the following commands:

corepack enable
yarn set version stable

⚠️ If you see any error messages, try running npm install -g corepack and then run the commands above again.

exec zsh

Then run the following command:

yarn -v

✔️ If you see a version, you're good 👍

❌ If not, ask for a teacher

SQLite

In a few weeks, we'll talk about databases and SQL. SQLite is a database engine used to execute SQL queries on single-file databases. Let's install it:

In a terminal, execute the following commands:

sudo apt-get install sqlite3 libsqlite3-dev pkg-config

Then run the following command:

sqlite3 -version

✔️ If you see a version, you're good 👍

❌ If not, ask for a teacher

PostgreSQL

Sometimes, SQLite is not enough and we will need a more advanced tool called PostgreSQL, an open-source robust and production-ready database system.

Let's install it now.

Run the following commands:

sudo apt install -y postgresql postgresql-contrib libpq-dev build-essential

sudo /etc/init.d/postgresql start

sudo -u postgres psql --command "CREATE ROLE \"`whoami`\" LOGIN createdb superuser;"

📝 If you get an error saying could not change directory to "/home/your_name": Permission denied that is totally fine, and there's no need to worry 💆 If, on the first run, it says CREATE ROLE in the end all worked fine.

You can configure PostgreSQL to autostart, so you don't have to execute sudo /etc/init.d/postgresql start each time you open a new terminal:

sudo echo "`whoami` ALL=NOPASSWD:/etc/init.d/postgresql start" | sudo tee /etc/sudoers.d/postgresql

sudo chmod 440 /etc/sudoers.d/postgresql

echo "sudo /etc/init.d/postgresql start" >> ~/.zshrc

Open a new terminal.

✔️ If you see a * Starting postgresql (via systemctl): postgresql.service OR * Starting PostgreSQL 14 database server message, you're good to go 👍

❌ If not, contact a teacher.

Check-up

Let's check if you successfully installed everything.

In you terminal, run the following command:

exec zsh

Then run:

curl -Ls https://raw.githubusercontent.com/lewagon/setup/master/check.rb > _.rb && ruby _.rb && rm _.rb || rm _.rb

✔️ If you get a green Awesome! Your computer is now ready!, then you're good 👍

❌ If not, contact a teacher.

Kitt

⚠️ If you have received an email from Le Wagon inviting you to sign up on Kitt (our learning platform), you can safely skip this step. Instead, please follow the instructions in the email you received if you haven't done so already.

If you are unsure about what to do, you can follow this link. If you are already logged in, you can safely skip this section. If you are not logged in, click on Enter Kitt as a Student. If you manage to login, you can safely skip this step. Otherwise ask a teacher whether you should have received an email or follow the instructions below.

Register as a Wagon alumni by going to kitt.lewagon.com/onboarding. Select your batch, sign in with GitHub and enter all your information.

Your teacher will then validate that you are indeed part of the batch. You can ask them to do it as soon as you completed the registration form.

Once the teacher has approved your profile, go to your email inbox. You should have 2 emails:

One from Slack, inviting you to the Le Wagon Alumni slack community (where you'll chat with your buddies and all the previous alumni). Click on Join and fill the information.
One from GitHub, inviting you to lewagon team. Accept it otherwise you won't be able to access the lecture slides.

Slack

Slack is a communication platform pretty popular in the tech industry.

Installation

Download the Slack app and install it.

⚠️ If you are already using Slack in your browser, please download and install the desktop app which is fully featured.

Settings

Launch the app and sign in to lewagon-alumni organization.

Make sure you upload a profile picture 👇

The idea is that you'll have Slack open all day, so that you can share useful links / ask for help / decide where to go to lunch / etc.

To ensure that everything is working fine for video calls, let's test your camera and microphone:

Open the Slack app
Click your profile picture in the top right.
Select Preferences from the menu.
Click Audio & video in the left-side column.
Below Troubleshooting, click Run an audio, video and screensharing test. The test will open in a new window.
Check that your preferred speaker, microphone and camera devices appear in the drop-down menus, then click Start test.

✔️ When the test is finished, you should see green "Succeed" messages at least for your microphone and camera. 👍

❌ If not, contact a teacher.

You can also install Slack app on your phone and sign in lewagon-alumni!

Windows settings

Exchange files between Windows and Ubuntu

We need an easy way to transfer files from Windows to Ubuntu and vice versa.

In order to do that, let's create shortcuts to Ubuntu directories in the Windows File Explorer:

Open the Windows File Explorer (or use the shortcut WIN + E)
In the Address Bar, enter \\wsl$\ (or \\wsl$\Ubuntu if it does not work)
You now have acces to the Ubuntu file system
Dive into the Ubuntu file system in order to look for directories of interest
Drag the desired folders into the Address Bar in order to create shortcuts

Open the Windows File Explorer from the Ubuntu terminal

Another option to move files around is to open the Windows File Explorer from the Ubuntu terminal:

Open an Ubuntu terminal
Go to the directory you wish to explore
Run the explorer.exe . command (alternatively, use wslview .)
If you get an input output error message, run wsl --shutdown in a Windows PowerShell and reopen an Ubuntu terminal

Find your way in the Ubuntu File System

You might want to figure out the exact location of a Windows directory in the Ubuntu file system, or the other way around.

In order to convert a Windows path to and from an Ubuntu path:

Open an Ubuntu terminal
Use the wslpath "C:\Program Files" command in order to translate a Windows path into an Ubuntu path
Use the wslpath -w "/home" command in order to translate an Ubuntu path into a Windows path
In particular, the wslpath -w $(pwd) command returns the Windows path of the current Ubuntu directory

Pin apps to your taskbar

You are going to use most of the apps you've installed today really often. Let's pin them to your taskbar so that they are just one click away!

To pin an app to your taskbar, launch the app, right-click on the icon in the taskbar to bring up the context menu and choose "Pin to taskbar".

You must pin:

Your terminal
Your file explorer
VS Code
Your Internet browser
Slack
Zoom
