Thinking Like an Algorithm in CST 370 This Week

This week, I learned about several important concepts in algorithms and data structures. From the recorded videos, I learned how pseudocode is used to describe algorithms in a clear and language-independent way. I also learned about different problem types, such as sorting, searching, graph problems, and tree data structures. Topics like graphs with vertices and edges, the Traveling Salesman Problem, and trees such as binary trees and binary search trees helped me understand how real-life problems can be modeled using data structures. The quizzes helped reinforce ideas like basic operations, time complexity, stable sorting, and graph properties.

One aha moment for me was understanding how binary search trees make searching efficient. By comparing values and choosing to go left or right, the search space becomes smaller very quickly. Another important realization was how sorting can improve searching performance, which explains why these two topics are often discussed together. I also better understood how pseudocode connects informal ideas to more precise algorithm descriptions.

For the homework, I chose C++ instead of Java, which I am comfortable with. Writing the palindrome program helped me practice handling strings, ignoring non-alphanumeric characters, and thinking carefully about algorithm logic instead of just coding quickly. Going forward, I want to focus more on time complexity analysis, especially understanding best case, worst case, and how different algorithms compare. I also want to learn more about graph and tree algorithms, since they seem very important and widely used in computer science.

Choosing Between MongoDB and MySQL

This week I learned more about how MongoDB and MySQL are both powerful tools for managing data, but they serve different purposes. MySQL is a relational database that organizes data into tables with rows and columns. It uses SQL (Structured Query Language) to define and manage data, which makes it very structured and reliable. MongoDB, on the other hand, is a NoSQL database that stores data as documents in a flexible JSON-like format . It does not require a fixed schema, so it is easier to change or add new data types as needed. Both databases are similar because they can handle large amounts of data, support indexing for faster searches, and allow users to perform queries to get specific information. They are also widely used in modern applications and can be connected to programming languages like Java, Python, or C++. However, the key difference is how they store and organize data. MySQL is best when data has clear relationships, such as in school systems, banking, or employee ...

CST462S - From Learning to Impact: My Service Learning Journey

What went well during my service learning experience was my ability to contribute meaningfully to the ASCENDtials web team. I was able to complete several tasks such as updating website pages, working on LifterLMS courses, and improving user experience through better layouts and navigation. I also communicated effectively with my team, asked questions when needed, and stayed consistent with meeting deadlines. Over time, I became more confident using tools like WordPress, WPForms, and course-building platforms. If I could improve something, it would be my time management and planning. There were moments when tasks felt overwhelming, especially when balancing schoolwork and service hours. I would also improve my confidence in decision-making, particularly when working independently on design or technical issues. Taking more initiative earlier and asking for feedback sooner would have made my work even stronger. The most impactful part of this experience was seeing how my work directly co...

CST438: Hands-On System Testing and Cloud Technologies

This week, I worked on both system testing and understanding cloud and distributed system concepts. One of the main things I learned was how to build Selenium system tests that simulate real user behavior. I created tests in which an instructor enters final grades and in which instructor-created assignments appear in a student’s view. While doing this, I learned how important it is to have all parts of the system running, including the frontend, backend, and external services like the gradebook. I also improved my debugging skills by fixing issues with Selenium, such as incorrect XPath selectors, missing UI elements, and unnecessary alert handling. I also learned how to properly manage my code using Git and GitHub. I created branches, committed my changes, pushed them to GitHub, and opened pull requests for review. This helped me understand a more realistic development workflow and how collaboration works in a team environment. In addition to coding, I reviewed several key concepts i...
