    Hi everyone, welcome to my 25th blog! This is the Week 1 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.
    • Despite it only being the first week in CST 334, there was certainly a lot to learn. This is especially true for me, as I have never programmed in the C programming language prior to starting this course. From the lecture videos, I got some review in computer architecture, which comes up quite often in operating systems due to their low level nature. In addition, the lecture videos also covered Linux and the shell, programming in C, an introduction to the command line, and a math addendum primarily focusing on the conversions between binary, decimal, and hexadecimal. For the readings of this week, I read OSTEP Chapter 2. Topics covered in this chapter include virtualization of the CPU, virtualization of memory (RAM), concurrency, persistence, design goals, and some history on the development of operating systems. In addition, I spent some time learning "How to Read a Paper" which is intended to help with the upcoming group research project in this course. Assignments tied to the lecture side of this week include watching videos 1.1-1.6, Lab 0, Quiz 1, and the Week 1 Discussion.

    • On the development side of this week, it was more or less an introduction to the C programming language. There were two assignments: Lab 1 and Programming Assignment 1. Lab 1 acted like a precursor to Programming Assignment 1, allowing you to develop skills necessary to tackle the larger programming assignment. Specifically, how to understand and utilize the GNU Project Debugger (GDB). The programming assignment certainly had a lot of functions to write, however I followed Dr. Ogden's advice of focusing on the higher point functions, then circling back to complete the lower point functions. Another good piece of advice is reusing certain functions in more complex functions. An example of a function that I used in many other functions is String__length(). I also went through the effort of earning the extra credit point (lint check), bringing me to a score of 101/100 on Programming Assignment 1 :)

    That is all for this week, see you in my Week 26 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...
