Developing with Frontend & Backend
To get started with development, you need tools. You'll learn how to get the necessary tools here using Conda scripts.
GitHub
- What is GitHub?
Github is a digital portfolio for storing collaboration. - Why do we use GitHub? Why not Google Drive or messages?
Github is built specificly for coding. - What's the difference between Git and GitHub?
Git is a tool that manage multiple version of source code and github is a application. - Name as many Git commands as you can:
Push, pull, sync, and merge.
Two Main Machines
- Which is better, MacOS or Windows?
Windows is better because it's compatiable with more extensions. - Give some differences between MacOS and Windows in terms of the development we use in APCSP:
They have different command in command prompt. - If you are on Windows, you want to skip the MacOS Setup instructions.
Our Tools:
- What is the first tool you remember installing?
Vs code - Why was installations so hard the first time?
Because the machine was not setup for programming and there were some incompatibility. - Without looking back at previous notes, name three tools you remember installing. This can be kernels, extensions, any installation for APCSP, and also write why it is needed.
jupyter, python, javascript, bash.
Actual Installations:
Tool setup is a week 0 thing. You should already have the knowledge to set up your machine. There is also a high chance you had to remove your environments and set up your machine again due to errors. If, for some reason, these don't apply to you, go here to set up your machine, here to check everything working with Bash, and here for Docker setup, which are the main tools on our machine needed to develop in APCSP.

By now, you should already know how to clone Git repositories into your VSCode directory. Once you do that, you're all set for developing with GitHub Pages and Fastpages!
Before We Set Up Pages, A Guide to Git
As we've discussed, Git is different from GitHub. Because GitHub is merely the place where we store Git repos, we use Git's commands to help us get, open, and configure these repositories. Here are some of the Git commands you should be using a lot (In the comments, tell what each Git command does):
git clone {repos-name-here.git} # what does it do?
# it clone a github repository to vscode so you can commit.
git checkout [branch] # what does it do?
# Switch branches or restore working tree files
git fork {repos-name-here.git} # what does it do?
# a copy of an existing repository in which the new owner disconnects the codebase from previous committers.
git commit -m {"commit-msg"} # what does it do?
# It commit the changes so you can sync it
git pull # what does it do?
# It pull the updated data frem github
git push # what does it do?
# It push your change to github
# After this line, name other commands that you can use and what they do. This should be easy, as you've already answered the qeue
# We could also use git merge that merge branches and changes.
Setting Up GitHub Pages
Some of you may have come to know that GitHub Pages is starting to become outdated. So why do we still use it? The answer is that we are in a class, and following a curriculum with something like GitHub Pages is much easier than creating portfolio content from scratch, which becomes quite unecessary. Therefore, we can use GitHub Pages to create this content instead. On the topic of unecessary vs necessary coding, we don't need to make GitHub Pages from scratch as opposed to using a template that our very own Mr. Mortensen created for us. To do that, we can go to the Leuck Reunion repository and use the template to make our own GitHub Pages. Then, in Ubuntu, we can git clone our repository and open it in VSCode. After we have it open, the last thing we want to do is set up local hosting for this website, so that we can preview it and make changes in real time. To do that, head here to install Jekyll for Ubuntu, here to install Ruby next, and here to finalize the process by installing Bundler.
Setting Up FastPages
In Setting Up Github Pages, we talked about how it is easier to use a template to create portfolio content. It is also easier to use a template when creating the portfolio itself. To do that, we can use Fastpages, which is what we have been using to show our blogs, code, and projects. However, Fastpages has been deprecated for some time now, so the instructions in Week 0 won't be effective. So, we need to fork the APCSP Fastpages. To do that, follow this video to get started developing with Fastpages.
