    Hi everyone, welcome to my 31st blog! This is the Week 7 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 7 had about the same amount of material of other weeks with a total of four chapters. The lecture videos help recap these textbook readings, covering concepts such as I/O devices, hard drives, files and directories, file systems (data), and file systems (access). The latter two videos both come from OSTEP Chapter 40, they are just split between "a" and "b" based on a data or access focus on file systems. For the readings of this week, I read OSTEP Chapters 36, 37, 39, and 40. Assignments tied to the lecture side of this week include watching the aforementioned lecture videos, Quiz 6, and the Week 6 Discussion. This week, each contributor finished up their portions of the group project video. The idea of using the scripts to translate well for the group summary seemed to also pay off. In addition to these two group-related segments there are two individual segments: the  peer assessment and personal reflection. Finally, there was an extra credit opportunity available by filling out the survey sent out by the CS Online advisor, Kayla.

    • While Week 7 did not have a Programming Assignment, it did house a lab on persistence calculations. The types of problems present in this lab included calculation of hard drive access times, calculation of inode access, and determining the operation executed between two Very Simple File System (VSFS) states. The VSFS problems are based on this Python simulation made by the authors of our textbook.

    That is all for this week, see you in my Week 32 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...
