CST 325 - Module 2

 Week 2,

The core concept of the module is rather fascinating. In short, we learned more about ray tracing, where we shoot a ray into what would be considered a pixel in an imaginary plane, which looks for something to “hit”, using that we draw the pixel based on what we hit. If there is a light source, we compare the point to the light source, and the hit objects normal to shade the pixel. However, if we want more detail, such as reflections, we can create another ray from the hit point and repeat the process recursively, then take the combinations of those colors and apply it to the pixel. This is also a similar process to casting shadows, except instead of looking for the color of the hit object, we are just interested if there is an object between the point and the light source. I also learned more about simple anti-aliasing which is just shooting out more rays per pixel in a certain pattern, then averaging the returning colors between each ray, then drawing the pixel.

This was all implemented in our programming assignment with my partner, and it went well.

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...
