Installation Hack

It is fundamental that you learn how to create your own blogging website and understand the following concepts:

Shell Commands

  • Take note and describe the type of shell commands you are using through Terminal in this installation procedure. This is specific to your machine.
    • Examples: wsl, cd, git, apt, brew, etc.

Version Control

  • In the development process, developers use version control. Annotate in your notes what you have learned about version control during this setup process.
    • How are the files from GitHub placed on your local machine? How do you navigate to those files?
    • How are the files updated in GitHub? How do you navigate to those files?
    • How would you update your template of the student_2025 repository? How would you make it more applicable to your specific course?

Localhost vs. Deployed Server

  • Put into words the difference between viewing GitHub Pages running on your localhost machine versus running on a deployed server.
    • What is the localhost URL for your project? Can anyone else see what you see?
    • What is the GitHub Pages URL for your project? Can anyone else see what you see?

DNS and GitHub Pages

  • DNS is the address manager for the internet. Reflect on the following questions:
    • Is there a domain on your GitHub Pages?
    • Is the URL for your GitHub Pages different from your neighbors’ URLs? Did you change the URL? If so, when?

By completing these “Hacks,” you will gain a deeper understanding of the tools and processes involved in setting up and managing a development environment, version control, and deploying a website.

Terminal and Linux Shell Navigation

You are expected to identify your computer type, know its operating system, and manage folders and files effectively.

Each computer type—Windows/WSL, MacOS, and Chromebook using KASM student workspace—provides an option for a Terminal.

As you proceed, you will be running Linux shell commands in your Terminal.

  • Explore or research Linux shell commands such as cd, pwd, mkdir, etc.
  • Click for Linux navigation commands.
  • Use Google or chat tools for questions like “What is Linux cd?”
  • Learn how to open a Terminal in your workspace.

Be mindful that different workspaces will have distinct setup and installation requirements. However, after the initial setup, we will aim to make our workspaces as similar as possible.

Windows Subsystem for Linux (WSL) Setup

WSL provides a Linux terminal environment on a Windows computer. Linux is an open-source operating system with many distributions, such as Ubuntu Linux, which we will install and use. Once we install Ubuntu Linux, we will be able to run Linux/Unix commands. Ubuntu includes a package manager called apt that allows us to add developer packages and libraries to the machine.

To get started, download WSL and Ubuntu 22.04:

  1. Open PowerShell as an administrator (Right-click -> Run as administrator) and type: wsl --install -d Ubuntu-22.04

  2. After the installation finishes, restart your computer.

  3. After restarting, a command prompt or PowerShell prompt may automatically open, asking for a username. Enter a username and password to create your account. Note, that the password will not be visible as you type, but it is still being registered.

    If no prompt opens, open PowerShell as an administrator and run: wsl --install -d Ubuntu-22.04

  4. Open Command Prompt or PowerShell as a regular user (just click on Command Prompt or PowerShell), and type wsl. The terminal’s prompt should change from PS C:\Users\<username> to <username>@MSI:. You are now ready to use Linux/Unix commands.

  5. To set Ubuntu 22.04 as the default WSL distribution, run: wsl --set-default Ubuntu-22.04

WSL (Reference, shows WSL commands)

As a WSL user, refer to these PowerShell commands for troubleshooting or configuration changes. These are used to correct or set up WSL, thus all WSL commands work at the PowerShell prompt PS C:\Users\<username>.

  • List all WSL commands: wsl -h or wsl -help
  • List installable WSL distros: wsl -l -o
  • List installed WSL distros: wsl -l or wsl --list
  • List installed WSL distros with status and version: wsl -l -v or wsl -l --verbose
  • Run the default WSL distro: wsl
  • Run an alternate distro: wsl -d <distro_name> or wsl --distribution <distro_name>
  • Shutdown a specific distro: wsl -t <distro_name> or wsl --terminate <distro_name>
  • Shutdown all distros: wsl --shutdown
  • Set a specific distro as default: wsl -s <distro_name> or wsl --set-default <distro_name>

WSL VSCode Install

VS Code provides a place to create and edit code. Follow the steps below to download VS Code onto your computer.

  1. Install VS Code

  2. When the installer asks to Select Additional Tasks, check “Add to PATH”.

  3. Open VS Code. In the sidebar, click on “Extensions”. Search for “Remote Development extension pack” and install it.

MacOS Setup

VS Code provides a place to create and edit code. Homebrew is a package manager that simplifies the installation of developer tools.

MacOS VSCode and Homebrew Install

MacOS terminal supports Linux/Unix commands by default. To enhance its capabilities, we need to install Homebrew.

  1. Install VS Code:
  2. Install Homebrew:
    • Open the Terminal and run the following command to install Homebrew: 
      /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
    • Follow the on-screen instructions to complete the installation.
  3. Verify Homebrew Installation:
    • Run brew --version in the Terminal to ensure Homebrew is installed correctly.

Install Developer Tools

At this point, your machine, operating system, and workspace are prepared for additional developer tool installations. (For KASM workspace users, this is where you enter the process, as images have been set up for development.)

Before continuing, it is crucial to understand the purpose of a package manager. A package manager is used to install key developer tools and packages. Examples of tools include Python, Java, and various frameworks for web development, databases, and data science.

Here are some references that may assist you if you encounter any issues while following the procedures.

Ubuntu, for WSL and KASM workspace users (apt-get or apt)

  • Update package list: sudo apt update
  • Upgrade installed packages: sudo apt upgrade
  • Install a package: sudo apt install <package_name>
  • Remove a package: sudo apt remove <package_name>
  • Search for a package: apt search <package_name>
  • List installed packages: apt list --installed

MacOS users

  • List installed packages: brew list
  • Search for a package: brew search <package_name>
  • Update Homebrew: brew update
  • Upgrade installed packages: brew upgrade
  • Uninstall a package: brew uninstall <package_name>

With the package manager references in hand, you are now ready to proceed with the detailed instructions for installing the necessary developer tools. Follow the steps specific to your operating system to ensure a smooth setup process.

If using KASM Workspace Ubuntu terminal

Perform steps in either option A or option B below to install Gems

# Option A -- Most tools have been pre-installed. Run shell command to automatically finish tool setup. 
~/vscode/portfolio_2005/scripts/activate.sh

# Option B -- Run Ubuntu commands manually to manually finish tool setup. 
# Install Gems
export GEM_HOME="$HOME/gems"
export PATH="$HOME/gems/bin:$PATH"
echo 'export GEM_HOME="$HOME/gems"' >> ~/.bashrc
echo 'export PATH="$HOME/gems/bin:$PATH"' >> ~/.bashrc
gem install jekyll bundler

Version Checks

From here the steps for all should behave the same.

  1. Close existing terminal!!!
  2. Then start a new terminal. Start and stop are required to make sure changes to you machine have taken effect.
  3. Run each check below, if the check does not work, you will need to backup to resolve it now!!!
# Show the active Ruby version, MacOS is 3.1.4
ruby -v

# Show active Python version, it needs to be 3.9 or better
python --version

# Setup Python libraries for Notebook conversion
pip install nbconvert  # library for notebook conversion
pip install nbformat  # notebook file utility
pip install pyyaml  # notebook frontmatter

# Show Jupyter packages, nbconvert needs to be in the list
jupyter --version
# Show Kernels, python3 needs to be in list
jupyter kernelspec list # does not work on Cloud Ubuntu

Open a Project

Learn to use Terminal, VSCode, and GitHub. Use VSCode’s connection to GitHub to pull and sync code.

Git Clone and VSCode Launch

Follow the steps in order. References to WSL are not applicable if you have MacOS or Cloud Ubuntu.

  1. Open a Linux-supported Terminal

  2. Setup personal GitHub variables: Change youremail@gmail.com and yourGHID to match your credentials. This is required prior to syncing code to GitHub.

     git config --global user.email youremail@gmail.com
 git config --global user.name yourGHID

  3. Move to your home directory:

     cd

  4. Setup a directory for projects:

     mkdir nighthawk 
 cd nighthawk 
 git clone https://github.com/nighthawkcoders/student_2025.git

  5. Open the repository in VS Code:

     cd student_2025
 code .

  6. WSL only!!! Very important!!! Check that VSCode is opened in WSL, observe at the bottom left corner of the window. This is a requirement for grading.

Development Cycle

The development cycle involves iterative steps of making changes, running the server, testing, committing, and syncing changes to GitHub.

Bundle Install and Make Steps

All students are building a GitHub Pages website.

The following commands are the same for all machine types, terminals, and projects. The previous installation steps were to ensure all environments are compatible.

  1. Open your terminal in VS Code through View -> Terminal. Alternatively, the shortcut Ctrl + ` can be used. (Opening up VS Code’s terminal opens your student repository in the project directory.)

  2. Type bundle install This command installs the dependencies in your Gemfile.

  3. Type make This runs the local server. Repeat this command as often as you make changes.

  4. Hover then Cmd or Ctl Click on the Server address http://127.0.0.1 … provided in the terminal output from the make command.

Make commands (local build: make, make clean, make stop, make convert)

These commands are used to build and manage a localhost version of website. The purpose of this is to verify and test code changes prior to pushing changes to GitHub Pages.

  • make Runs the local server.

  • make clean Stops the local server and cleans the files.

  • make stop Stops the local server. This means you will be unable to access your blog on http://localhost until you run make again.

  • make convert Converts Jupyter Notebook files. Run this if your .ipynb files are not updating on the server, it may assist in finding the error.

VSCode Commit changes

The VSCode saved files are only stored on your computer locally until you commit/sync the changes. If you visit your actual blog on the web (https://.github.io/student_2025), you will notice that the changes are not reflected there. To ensure that the public website updates, you will need to **commit and sync your changes in VSCode**; this will push changes to GitHub and trigger a rebuild of the website.

Commit Changes, version control locally

This creates a version update in your local git database. Developers often commit several times before they sync/push. This allows for many small changes that can be easily reviewed and rolled back. Review COMMITS in VSCode.

  1. Click on the button that says “Source Control” in VS Code’s left sidebar

  2. Click on the plus sign to stage your changes

  3. Enter a message for your commit in the message box.

  4. Click the “Commit button”

Sync Chaanges, update change in GitHub

This moves commit(s) from the local git database to GitHub. This will create an Action in GitHub Pages and trigger an update to the website if the code is error-free.

  • Click the Menu button and then click “Push”.
