    Hi everyone, welcome to my 27th blog! This is the Week 3 post for CST 334 Operating Systems.
  • Write a 1-2 paragraph journal post, of at least 250 words, of what you learned this week in CST 334.
    • Week 2 and Week 3 had the same amount of chapters to cover. The lecture videos help recap these textbook readings, covering concepts such as address spaces, the C memory API, address translation, base-and-bounds, segmentation, and free space management. For the readings of this week, I read OSTEP Chapters 13, 14, 15, 16, and 17. Topics covered in these chapters reflect those discussed in the lectures but with more detail. Assignments tied to the lecture side of this week include watching the aforementioned lecture videos, Quiz 3, and the Week 3 Discussion. In relation to the group research project, my group Silicon Surfers decided to do the group project on the paper I chose, called Triangulating Python Performance Issues with SCALENE. Finally, there was an extra credit opportunity available by filling out the survey sent out by the CS Online advisor, Kayla.

    • On the lab/development side of this week, it was essentially applying the theories of memory virtualization. There were two assignments related to this: Virtual Memory Lab (Part 1) and Programming Assignment 3. Virtual Memory Lab (Part 1) gives a lot of practice on how to calculate memory management problems by hand. This activity develop a practical and calculative understanding of memory management concepts. Unlike Programming Assignment 2, I found this one to be less straightforward. It took me a while to realize that this project used a doubly linked list type data structure to organize the nodes. However, upon this realization, it made managing the nodes a bit easier.

    That is all for this week, see you in my Week 28 post!

Week 32 (8/13/2025 - 8/15/2025)

     (Click on READ MORE for better formatting)      Hi everyone, welcome to my 32nd  blog!  This is the Week 8 post for CST 334 Operating Systems. Write a 1-2 paragraph journal post, of at least 250 words, summarizing what your biggest takeaways from CST334 were, including any major challenges or topics you found particularly interesting. One of the major challenges in this class (at least for me) was wrapping my head around some of the long math-style problems that have been seen throughout the course. Thankfully, I was able to get a lot of practice with these through labs, ungraded practice quizzes, Midterm Preparation Quiz, and Final Exam Preparation Quiz. In addition, members of my team were able to help me better understand what was needed to tackle these problems. For example, Wootark Kim (Tom) made a step by step video for me and the rest of Silicon Surfers that explained how to do CPU scheduling problems featuring the RoundRobin policy. V...

Weeks 41 - 48 (10/26/2025 - 12/19/2025)

     (Click on READ MORE for better formatting)      Hi everyone, welcome to my 41st-48th  blogs!  This is the Week 1-8 post for CST 336 Internet Programming. Similarly to CST 311 Introduction to Computer Networks, while journal entries were not required  for this particular course, I wanted to document the concepts and assignments from each week of class. If you would like to see some of these projects for yourself, this link acts as a homepage to visiting all of the projects described below! https://bevans34.github.io Week 1: HTML and CSS This week's primary focus was on learning/practicing creating a website using H yper T ext M arkup L anguage (HTML) and C ascading S tyle S heets (CSS). Highlights from this week included centering a <div>, which is probably one of the biggest memes to ever come out of web development. Labs: 1 - ePortfolio Site In this lab, I created a site hosted on GitHub Pages that features a homepage, about page,...

Week 24 (6/18/2025 - 6/22/2025)

       (Click on READ MORE for better formatting)      Hi everyone, welcome to my 24th  blog!  This is the Week 8 post for CST 363 Introduction to Database Systems. Briefly summarize what you consider to be the three (3) most important things you learned in this course. How to query in MySQL and MongoDB, including select, insert, update, and delete. This also includes advanced querying techniques, such as subselect. Understanding schema structure of MySQL and MongoDB. After all, for the above to work you need a schema to create/use the database and establish table structures! Creating EER diagrams can also be bundled into this section as it is related to schema creation. How to take database systems and turn them into real-world solutions. For instance, using the JDBC API to create a webapp with a MySQL or MongoDB foundation. This was explored in group labs 19 and 21. That is all for this week, see you in my Week 25  post! Onwards to CST...
