Week 1 - Introduction, Github, Command Line

We might not get through everything, but we'll get as far as we can.

What different programming languages are for and how they work together
How to use the command line to execute some basic commands on your computer
How to publish up a website you made from scratch using Github pages
How to follow the same workflow as professional developers when coding (and why they do things this way)

Come up with a project that you'd like to work on for the next 2-3 weeks. Could be something that works well with your other classes. Should definitely be something you don't already know how to do, and I'll guide you through it.

Today's Session

What is Git?

Version control for coders
- Why do coders need version control?
  - Sometimes your code just breaks and you need to go back
  - Collaboration
  - Think of it like "track changes" or "revision history"

What is Github?

Who uses it?

How does Github work exactly?

Four basic commands to sync the code on our computer to the repository hosted on Github

git status
git add .
git commit -m "Updated design"`
git push

Creating 'branches' and using a branch called 'gh-pages' to create our own website

git branch
git branch gh-pages
git checkout gh-pages
git push origin gh-pages

What else is possible? Github's excellent cheatsheet. They also have a tutorial.

But before we try any of these commands themselves, we need to know some Command line basics.

Command	Example	What it does	Notes
pwd	pwd	Shows your present working directory	Useful for keeping track of where you are
ls	ls	Shows the contents of the current directory	Can also use ls -a or ls -l to show more information about files
cd	cd Desktop	Changes directories	Use cd ..``` to move backwards
mkdir	mkdir new-directory	Creates a new directory
touch	touch test.py	Creates a new file
mv	mv test.py ./Desktop	This isn't covered above, but mv moves or renames a file.
rm	rm test.py	Deletes a file	Use with extreme caution. Once a file is deleted this way, you can't get it back.
