Classes

I wanted to write a summary of some of the courses I’ve taken, as well as how I felt about them. It might be useful as a guide to future people taking the courses, but it may also serve as a personal reminder of what I’ve done. It will mostly focus on the emotional aspect of these courses, and how I felt about them. The content is more easily seen in something like a syllabus, which is probably easier to find elsewhere.

First Year

Intro to Systems

This class was by far the shittiest class I’ve ever taken, for reasons beyond the class itself. Before explaining my hatred, to summarize the class, it’s essentially an introduction to low-level programming (C + x86), as well as some common applications like an allocator or doing stack overflow to read hidden values from a program. The premise is interesting, and can be a good utility for showing students systems programming. I don’t think the content is particularly inspiring, but it will suffice to help people be aware of what exists. I don’t think that a deep understanding is provided though, since the class encourages 0 discussion. My main beef with the class is that the professor when I took it was wholly convinced that C is a shitty, unsafe language. One of the questions on the final exam’s entire purpose was to suggest to use Java. In a systems programming class, this is absolutely shitty. Yes, C is unsafe and dangerous, but it’s also blazing fast. And the lecture was intended to show that “modularity” and “abstraction” are one of the main points of systems programming. For a standard programmar, yes, you don’t care about what’s under the hood, and you shouldn’t have to if you want to stay sane. But if you are the systems programmer, you should be curious about every detail, and want to know how to pop the trunk and change shit. I feel like the professor, (and due to his influence, the teaching staff), killed any curiosity people had in the material. Finally, the professor decided to pull the last assignment, which was making a Unix shell, instead making Othello. Fuck that noise. If the professor ever taught a class I might have taken after that, I avoided it. As this was my first CS class, it was a fantastic intro to CS courses in Uni. As compared to self-learning the concepts, draining and the course content does not care about the end result.

Intro to Algorithms

I don’t feel anything particularly strong about this class. A lot of people who are interested in CS will take this class out of interest, so a lot of the content is designed to be good for people across the board. Thus, there’s a significant amount of busy work, writing down algorithms and solving them manually every friday, pre-recorded lectures before COVID was hip. I found this mass-served content to not be particularly interesting, and that most of the content could be useful, but I couldn’t tell at the tiem if it was or wasn’t. Even in retrospect, I’m not sure whether anything I learned was good. I also realize part of the class was still teaching people how to program, and making people more confident in their ability to program. One thing I’d also note about this course (and Intro to Systems), is that there is a significant amount of hand-holding. To be specific, you can go to office hours, and they will help you debug, figuring out what is wrong with your understanding, and helping you find bugs in your code. I feel that this kind of hand-holding ends up getting un-learned in later classes, where there aren’t enough resources for the admin to maintain it (and they shouldn’t maintain it either). Probably, the most egregious thing is either papering over someone’s understanding, or figuring out their understanding for them. The one thing I enjoyed from the course was a competitive aspect, since there were leaderboards. I found I could just focus on the systems component, either adding built in parallelism, optimizing for the Java GC, using bitwise operations, and that would be sufficient to do well (which might be antithetical to the course). But doing shit that isn’t intended is always the most fun.

Functional Programming

I felt this class to be mostly lackluster, although it may be more useful depending on what field of programming/research someone is focusing on. The first few assignments are mostly just focusing on OCaML (which is a shitty language, fuck you Jane Street). That’s fine, it can be difficult to learn functional paradigms, but I think the assignments basically only taught syntax, whereas they could’ve also been more compressed in terms of adding in components of mutual recursion, continuation-passing-style, or other things. As compared to seeing Lisp, I felt like my mind was not bent so much, although this may have been affected since I had seen Lisp before. Other than that, we also did proofs on programs, which from a research POV may be useful, but from a practicality perspective is pretty useless. The final assignment was semi-interesting, since we had to do parallelized map and reduce operations in F#, which seemed a bit more interesting. Generally, the course is fine, but I don’t know if it was necessary that I did it. Meh, whatever.
