CST 325 - Module 1

 Week 1,

This is the first week of the course CST 325 Graphics Programming. The first week serves as a refresher on some important math concepts and how we can use them to generate images. Some core points would be the concept of vectors and what they convey depends on the context of what we are trying to achieve. In the context of a point using the origin to the tip of the vector, or just a vector, giving us direction and magnitude, without caring about where it is.

Additionally, we were re-introduced to some vector arithmetic and the dot product, and how we can use it for many things, such as projection, finding an angle, etc.

The most interesting to me is the ray sphere intersection, where the goal is to find where the ray may intersect the sphere, resulting in a "hit", and if there is a hit, we do something with it. There can be many applications to this, such as rendering the sphere from "shooting" a ray throughout the screen. Or maybe a hit scan weapon in a game where we don't care about the bullet's velocity or weight.

The programming assignments are to be done with a partner, and my partner is one that I've had for a most courses by now, Meagan, so we are pretty accustomed to each other's workflows.

CST 311 - Module 3

 Week 3 This week's material was very more focused on the transport layer. One topic was multiplexing and demultiplexing. To sum the topic up, this is how data is handled from multiple sockets using a transport header. The multiplexing occurs at the sender, using the transport header containing the source and destination port number, then demultiplexing occurs at the receiver, which allows the receiver to deliver the received segments to the correct socket. There are also two variants of these, connectionless demux and connection-oriented demux.  More on the topic of connection and connectionless transport, connectionless refers to the UDP protocol and is considered bare bones, there is no handshaking and each UDP segment is handled independently. What makes it bare bones is the fact that there is no effort in flow control, delivering data in order, reliable data transfer. However, it can be implemented at the application layer. On the other hand, with connection transport (us...

CST 338 - Module 4

 This week in CST 338, there were few assignments to complete. This time we got to get our hands on Android Studio, where we created very simple app where android users can convert temperature °c to temperature °f, or vice versa. We also got to complete our first project, where we practiced inheritance using an abstract class, and concrete classes. However, besides that, we were also allowed to go back to our previous assignment, Markov, and have our teammates review each other's code. I worked with my teammate Ryan Matsuo  and after reviewing his code, I learned a few things that could help me in the future, like splitting a string using str.split() with a regex of "\\s+" instead of what I did which was more complicated. My strategy with solving the Markov assignment was that I started writing the code right away. I didn't put anything to practice into paper because I feel I can do the same thing in the code. I would read the prompt, create stubs for the methods to b...

CST 334 - Module 7

 Week 7, This week's topic covers persistence, more specifically, persistent storage. First we read about I/O devices and how they work. This includes the DMI, eSATA/SATA and USB, and how they can connect to an I/O chip to communicate to the CPU. This is important especially considering this is how we connect storage devices like hard drives. After learning more about how the hard drive works by spinning the disk and reading and writing to it using the disk arm and head as well as the important things stored in it such as the superblock, inodes, bitmap, and data region. To put everything briefly, there is a lot that goes on under the hood when it comes to reading and writing to the hard drive, with a large amount of effort being used to decide how to read/write to better optimize for performance, capacity, or persistence. After figuring that out, we also talked about file systems, which allows the OS to manage data on a hard drive or other I/O devices. There are different ways to d...
