CST334: Journal Entry Week 5





The topic of this week was concurrency. We learned about threads and how multi-threading can be more efficient, but introduces new problems that occur when trying to schedule threads. That’s where we dive in the idea of locks and how they atomize critical sections of code. Locks are used by the task scheduler to enable the use of concurrent threads without causing race conditions and other issues that prevent programs from executing properly. These concepts reminded me of database locks, it’s basically the same idea. The chapters we read also cover the concepts of lock-based concurrent data structures and condition variables which are another necessary component of scheduling for multiple threads.

CST438: Journal Entry Week 1

Q. What did you expect a course in Software Engineering would cover? A. I believed we'd be building desktop applications with graphical user interfaces. Q. After completing week 1, how has your opinion changed? A. It turns out we're working on web services instead. I think that my personal preference toward desktop apps over web-based ones, especially regarding sensitive information and potential security concerns, is why I had the wrong initial impression.

CST370: Journal Entry Week 3

Week 3 is ending already! We learned about brute-force string matching as well as depth and breadth-first search algorithms. I was already familiar with the divide and conquer algorithm design, but it was still good to read more about it. The homework this week was torture. The first program about Depth-First Search took me forever to do and I found the instructions to be confusing. The hint really saved me on that one. The second program was easier in the way that we just needed to use brute force over more complicated algorithms. Anyways that’s all for now. The midterm is coming up soon and I hope I’m prepared for it.

CST311: Journal Entry Week 7

We covered chapter 6 of the textbook which was about link layers, but that was overshadowed by the much bigger thing this week, the final exam. One difference I noticed between the midterm and the final was that the midterm had much more overlap with the pre-midterm questions than the final had with the pre-final. That didn’t turn out to be much of an issue since I still scored pretty well in the end. This class is basically over now. I’m not bothering with any more extra credit work since it won’t make a meaningful difference to my grade since I already have an A. There’s just the programming assignment 4, and chapter 8.9 quiz, and the week 8 journal, which I probably won’t have much to say in since I’ll have to turn that in within 4 days from the date this one is published. That’s all for now.
