This is a course on how to be a hacker. Being a hacker means a lot of things. It means:
-
wanting to know how and why computers work
-
being efficient / never repeating yourself
-
using and contributing to open source software
-
understanding the edge cases of your software
-
using tools in creative and unexpected ways
-
(occasionally) we combine all these together and break stuff
Hacking is a mindset.
I can't force it on you---it's up to you to embrace it.
For example, we'll be discussing many new tools in this course:
a version control system called git
,
an editor called vim
,
debugging tools called gdb
, valgrind
, and cppcheck
,
and we'll be going into quite a bit more depth on how to use the bash
shell and the Linux
operating system.
All of these tools are very weird.
Using them will make you uncomfortable.
At first.
But these tools are powerful.
Mastering these tools will make you a much more efficient programmer.
Once you've mastered them, you'll never go back.
There are two main projects you will work on in this course:
-
Your first four homework assignments walk you through the process of building your own unix shell. This is the biggest project you've undertaken so far. You'll be developing it as an open source project, and you will collaborate with each other at various points.
-
Your last homework assignment is to contribute to the open source community by improving the documentation on a project of your choice. Many of the required readings for this course were written by former cs100 students. If you do a good job on this project, future cs 100 students will be learning from you for years to come!
By the end of the course, you should be comfortable running your own open source projects and contributing to other people's projects.

IMPORTANT: If you want to contact the instructors about the course, you should NOT do it via email. Instead, you should report an issue via github. We will talk about how to do this in class. This is a system similar to the piazza system you may already be familiar with, but it is more popular for open source software development.
Our lectures will roughly follow this schedule. You should do the required readings before class. I will occasionally have unscheduled quizes to ensure you are doing the reading.

We will not be using ilearn in this course.
Instead, we will be using a course management system called gitlearn
.
This software was developed in part by previous cs100 students,
and you will be able to earn considerable extra credit by contributing to it.
We will be using this system as a case study in bash programming and the unix philosophy.
For details, see the gitlearn repo.
Every assignment specifies different collaboration policies. Some assignments will be individual, and some will be in a group. Follow the specified policy exactly!
I take cheating seriously. When I catch students cheating, I give them an F in the class. Then I forward your case to the academic integrity board and recommend that you be expelled from UCR.
All of your code will be run through an automated cheating detector. It is very good. It understands C++ better than you do and can find instances of cheating much more sophisticated than just copy and pasting.
