Course Introduction:
	Syllabus and Calendar
	Note about grading time and "neurotypical"
		It's a natural last priority
		But maybe I finally have it...
	COVID-19 adaptations
		None
	General description of projects
	Kernel Programming
		Why Linux?
		NetBSD and W2K
		Linux worked ok last time
	Isoptera

Role of the OS kernel:
	Kernel control and protected mode
	Storage (filesystems)
		- Multiple of these
		- FAT still common, but many have advantages
	Memory (virtual memory)
		- Protection of video memory, etc
	I/O and device drivers
		- Hardware independent programming
		- Lots of hardware is really the same
	Processes and scheduling
		- Multithreading
		- Time sharing and responsiveness
	Disk Operating System (was it?)
		- Protection of resources
		- Termination of stuck process
	Networking
		- OS Manages network access
	Security
	Loaders
	Security
	
Userspace:
	We won't spend a lot of time on userspace (that's cs253)
		It'll come up though
	UI, etc.
	/proc "filesystem"
	/dev
	/sys
	System calls

What's it written in?
	Kernel C
	Example:  read
	Example of function pointer struct:  file_operations

How do we do homework 1?
	I'll find some examples
	
So we have to learn kernel C!  It will be fun.
	It's fun because you can use memory in C
	Video Games and OHSA (Occupational Health and Safety Administration)
	C memory management...

Project 1:
	Feel free to start anytime
