We covered basic class logistics (also available on the course info page), and did Assignment 0 to get everyone set up.

We defined what "the shell" is, went over the history/background of the UNIX operating system and the shell as we know it today, and covered how to use basic shell commands.

Useful Resources:

• man pages (the system manual)
• cheat.sh
• devhints.io/bash

I used a non-standard command bat in my lecture demo; the software installation page contains installation instructions if you want to try it out.

We will learn how to efficiently process large datasets (or any other text-based data) from the shell using tools like regular expressions.

There's a great regular expression debugger at regex101.

We will learn how to write our own "scripts"—mini-programs that combine shell commands.

We will compare and contrast different programs commonly used to edit code; namely, the terminal editor vim and the graphical IDE (integrated development environment) Visual Studio Code.

We will delve in more detail into the environment command-line programs run within, including:

• how we configure programs
• how programs find data (the filesystem)
• how we can run multiple programs at the same time

We will also cover a terminal multiplexer called tmux; be sure to install it using the instructions on the software page

We will see two related concepts:

• how source code (in C and Python) is turned into a program
• how we can install programs shared by other people

We will learn how computers talk to one another across the internet.

We will learn how to keep track of, switch between, and merge different versions of our code using the popular version control system git.

We will learn how to collaborate with others using git and GitHub.

We will learn how to set up a system that can automatically compile, test, and deploy our code.

We will cover common debugging strategies and various static analysis tools that can be used to make programming easier.

We will introduce the concept of computer security, including different types of attacks you might see in the real world (and strategies to protect yourself from them).

We will see real-world tools used to verify people's identity and keep data secure even in untrustworthy settings (like the internet).

We will set up and run virtual computers on your real computers, both for security and for ease of software development and deployment.

We will set up a connection to a computer running on a "cloud" service, such as Amazon AWS, Google GCP, or Microsoft Azure, and run our own code on it. We will also set up a simpler service using a "serverless" platform, which is a convenient way of deploying code without much work.

We will look at how different types of media (text, images, audio, and video) are represented by computers, including the tradeoffs of different formats.
