CST 363 Learning Journal Week 1

Relational database tables and spreadsheets look similar with both having rows and columns.  What are some important differences between the two?

One important difference is that a relational database focuses on concurrency. The data that is presented to the user is always the most up to date representation of the data. If one user makes a change that change is reflected in the database and is kept current across all users. A relational database can also incorporate security an permissions that allow certain users different levels of access. 

Installing and configuration a database and learning how to use it is more complicated that just reading and writing data to a file.  What are some important reasons that makes a database a useful investment of time? 

I think databases are a useful investment of time because many of the applications we use or will build for the future will rely on organized data that can be accessed by users in appropriate and meaningful ways. To study for future treads, or even using machine learning all require the use of large data sets that need to be organized and curated. 

What do you want to learn in this course that you think will be useful in your future career? 

For me I believe that learning how to build and manipulate databases will be the most useful for my career. I am looking to get into mobile app development and databases are a critical component for most major apps today. I think many of the concepts learned in this class such as creating a database, defining a schema and model, will be useful to my future career.

CST311 Week 6 Journal

 This week, we developed a deeper understanding of the network control plane and explored routing algorithms such as Dijkstra and Bellman-Ford, focusing on how they determine the most efficient paths for data transfer. We also learned about the SDN control plane, which allows for dynamic network management and routing. In addition to the theory learned this week, we conducted a network lab exploring the use of a basic SDN controller using Mininet and Wireshark. We looked at how Internet Control Message Protocol (ICMP), can be used for network diagnostics, particularly for network troubleshooting with tools like ping and traceroute.

CST335 Week 7 Journal Entry

 This week I learned about input/output (I/O) devices and their interactions with the operating system (OS). Two types of devices I learned about were block and character devices. Block devices, like hard drives and SSDs, store data in fixed-size blocks and allow random access, making them ideal for large data transfers. Character devices, such as keyboards and mice, handle data streams one character at a time, supporting sequential access. The OS play a crucial role in managing these devices through device drivers that provide a standard interface to interact with the hardware. Performance characteristics of hard drives, such as seek time, rotational latency, and transfer rates, are pivotal in determining overall system efficiency. By calculating transfer rates for different workloads, I learned how disk access patterns significantly impact performance. Additionally, understanding RAID levels provided insights into how redundancy and striping enhance data reliability and performan...

Leetcode Practice Reflection 1.Two Sum

LeetCode Practice Reflection - 1. Two Sum Date:   19MAY25 What I Worked on Today: Practiced doing LeetCode Problem 1.Two Sum. What I Learned: - How to use the enumerate() function - How to optimize possible solutions after considering brute force methods - How to declare a new dictionary (key value pair) Code Snippet I Wrote or Studied: class Solution(object): def twoSum(self, nums, target): seen = {} for i, num in enumerate(nums): compliement = target - num if compliment in seen: return [seen[compliment], i] seen[num] = i In My Own Words: This function takes in a list of numbers and will return the index of the two numbers that add up to the provided target value. The way this program works is that it creates a dictionary called "seen". It will then iterate through the list of numbers and use the enumerate function to keep track of the index and the value of the specific item in the provided list. The for loop will calculate the compliment numbe...
