<!--Introduction-->
<h3>Intro to the Course</h3>
<p>
CMSCI 120 is the Introduction to Computer Science Course.
It is a freshmen level course that aims to serve as entry point for all
future computer science classes;
teaching not only basic coding, but how to properly think and function
like a computer scientist.
The course covers basic programming, problem-solving methods and the
development of lower complexity algorithms;
with a focus on the coding language, Python.

<!--Thinking Like a Computer Scientist, at the request of Professor Weiss-->
<h4>Thinking Like a Computer Scientist</h4>
<p>One of the most prominent struggles students may face during this
course is the adoption of a Computer Scientist's mindset.
The ability to understand a problem and think of the best solution to
said problem is much easier said than done.
If nothing else, a computer scientist's mindset should be the primary
takeaway from this course,
as it's a skill that no advancements in technology can really
replace.</p>
<hr>
<!--IDEs-->
<h4>Integrated Development Environments</h4>
<p>In order to begin programming, the use of an IDE,
or Integrated Development Environment, is required.
There are many popular IDEs,
each with their own sets of advantages or disadvantages.
Some of the more popular choices for Python are listed below to
experiment with.
However, it is highly likely that each professor to teach this course
will have their own preferred IDE,
and it is advised that you follow that preference.</p>
<ul>
<li><a href="https://thonny.org/" target="_blank">Thonny</a>
: A barebones IDE, popular for being open source and without any extra
features.
It’s downsides also happen to be said lack of features.</li>
<li><a href="https://code.visualstudio.com/" target="_blank">Visual
Studio Code</a>
: One of the most popular IDEs in general.
This IDE supports every known coding language through extensions,
not dissimilar to that of browser extensions.
The application is popular for a reason,
and is almost guaranteed to be used by every Computer Science major
during their undergraduate studies.</li>
<li><a href="https://www.jetbrains.com/pycharm/"
target="_blank">PyCharm</a>
: The most popular Python specific IDE.
Recommended for its built in advanced code analysis,
debugging, and database integration.
As opposed to the other IDEs mentioned,
PyCharm's downside comes from some features being paywalled behind a
'Professional Edition'
of the application.</li>
</ul>
<hr>
<!--Debugging, at the Request of Professor Rittie-->
<h4>Debugging</h4>
<p>Debugging is a skill, that any programmer worth their salt,
will use actively during any application development.
The skill is, in short, the process of finding errors in code,
processing the output error message, and fixing said errors.
While many LLM and AI based tools have reduced perceived need for this
skill,
it is still very much an integral part of the computer scientist's
toolkit.
Below are a few debugging approaches that can be helpful in the
occurrence of malfunctioning code.</p>
<ul>
<li>Isolate: If something's confusing, try to break the code down into
its simplest parts that you can have.</li>
<li>Binary Search: Brute forcing the code, removing bits piece by piece
until the code eventually runs. This method excels when nothing sticks
out just by looking at the code itself.</li>
</ul>
<hr>
<h4>Outside the Class</h4>
<p>Depending on the professor, it is possible for the amount of work
outside class time to vary greatly. The biggest piece of advice that can
be given, especially in the age of LLMs and AI, is to simply not use
them. When encountering a hard problem to solve, if you solve it by hand
you'll remember the solution. However, if you give the problem to
ChatGPT to solve instead, you don't gain this muscle memory and don't
learn anything in the process.</p>
<p>It is important to acknowledge that while, yes you can in theory use AI
to pass many of your classes; you'll only get as much out the classes as
you put into them. It's important to experiment outside of class. If you
want to build a videogame, then build one. If you want to design your
own website, then do it.</p>
<p>Even if you get all of your knowledge and code from Google, you still
learn and apply new knowledge; and all of this will eventually become
second nature.</p>
<hr>
<h4>Resources</h4>
<p>Below are a series of completely free resources that not only explain
Python, but also help with processes such as adapting a Computer
Scientist's mindset, or learning how to add to your resume as a newcomer
in the tech industry.</p>
