Practical Computer Science Fundamentals

CompSci degrees cost a lot of money, take a lot of time, and aren't a viable option for a lot of folks. Luckily, much of what you'll learn in a proper Computer Science program can be self-taught online for free. This gist is a roundup of some of the most helpful resources I've found.

Where I'm coming from

I'm not pursuing a deep, academic comprehension of CS concepts — my goal is to become respectably conversant about the most prevalent and relevant subjects in the field.

How to install

1. Get fzf
2. Install all-the-package-names globally: npm i -g all-the-package-names
3. Add the following alias to your .bashrc: alias npmi = 'all-the-package-names | fzf | xargs npm install'

How to use

Just use npmi instead of npm i <package-name>. All options work (--save, -g etc).

How to test NVDA screen reader behaviour on a Mac:

1. Download Microsoft Edge VM from https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
2. Download Virtualbox and import the Edge VM image.

Then in the VM:

1. Install guest addons in the VM
2. Download & install latest NVDA from nvaccess.org
3. Download & install SharpKeys and use it to map left an alternative key (eg. Left Ctrl) to the Insert key. This is needed because Macs do not typically have an “Insert” key which is the prefix for many NVDA commands.

	# The old way:
	print("HELLO") 			# Code before the yield
	# Setting up the yield:
	var t = Timer.new() 		# Create a new Timer node
	t.set_wait_time(5.5) 		# Set the wait time
	add_child(t)			# Add it to the node tree as the direct child
