Computer science is the science of abstraction.
In lectures, I sometimes present my high level analysis for all movies. The protagonists face challenges and adversity and discover the true meaning of love and friendship. This works for Casablanca, Gone with the Wind, Star Wars, Rocky, etc. It occurs to me that this course has been a similar journey. As a student, you faced the challenges of the problem sets and exams, and now, I conjecture that you have achieved, if not a love of computer science, at least friendship with Python, UNIX, and recursion.
In biology, ontogeny recapitulates phylogeny In computer science courses, pedagogy recapitulates ontogeny (and phylogeny). That is, the order of presentation of topics in a course generally follows the historic order of development of the field. This is not some mere convention. Just as the developments in the field depended on earlier discoveries, the student's understanding of advanced concepts builds on a comprehension of more basic ideas. Newton famously stood on the shoulders of giants.
The topics in this course included the following:
Rank the topics from the course in order from most useful or interesting (top) to least useful or interesting (bottom).

Here's a limerick about the one-time pad: A cipher that's perfectly strong Uses keys that are random and long Each bit is XOR'd once (No cryptanalyst hunts!) But key sharing still goes quite wrong Or another one: There once was a pad, oh so keen The most secure cipher you've seen But the key must be new And as long as words too— Perfect crypto, but hard to routine!
My advice is to write as many C programs as possible over the break.
All good. I recommend that you also create a LinkedIn account as an online resume. I invite all of my Yale students to connect to me on LinkedIn to leverage my network, such as it is. I also am interested in following your trajectory, but not in a creepy way.
Here is a practice final exam and practice final solutions.
Here are the important concepts from Stamp:
Shell scripts: I might ask you to write a shell script. You should know the for loop.
The following topics were part of this course and are in scope for the final:
If your grade on the final exam is higher than your lower midterm grade, it will replace that grade. The quality of mercy is not strained.
Alas, we did not get to machine learning. See scikit learn aka, sklearn. Python module for machine learning. Machine learning jupyter notebook
See hw7hints.py You may need to install the module: wordsegment. (May need to run on lion using python 3.10. Sigh.)
pip install wordsegment
Review of encode and decode shell scripts. See openssl man page.
openssl --help
openssl enc --help
Startup file for mac terminal: ~/.bash_profile instead of ~/.bashrc
