CSC104 October 6th


I choose CSC104 for several reasons, such as my curiosity and studies. I always wanted to know how programing feels like. Specially, in this world where the technology is always developing and interacting with ourselves is necessary to know about how programs work. Additionally, CSC104 will provided with the basis for my developing knowledge and for a better understanding of Cognitive Sciences which is my current major.  Having said that, I expect that the course will give me the basic tools to understand in deep some of the computer concepts and theories that I study.
I always thought that programing was going to be boring, but I was wrong. In this course, I realized that learning the different commands and concepts is interesting. I had this pre-concept of programming because I previously had learned how to use some FSL, which has many differences with Dr. Racket. This is because FSL is predominately for fMRI analysis, while DrRacket is more a multi-paradigm program. That is why I have found it exciting so far, specially how we can create new functions with the definition command. Because of that, I would say that DrRacket is a more interactive language of programing that allow us to play a little bit with our creativity and the different commands. Although, sometimes it is tricky with some of the concepts such as list and apply. This made me reflect that the course indeed is harder than I expected to be. However, making the weekly exercises for the quizzes’ preparation has helped me to overcome some of the difficulties that I had in mastering the material. Thus, I will say that I feel satisfy with my performance in the quizzes because the weekly exercises usually give me a good practice of what topics I am going to be tested. Finally, I would just like to add that some of topics of interest for me are binary numbers and artificial intelligence

CSC WEEK 9

Along with the concepts of colors, we started the animations topic. In fact, an image is not animated if does not change somehow. To change an image, we use the function repeated which takes 3 inputs: a function, an image and a number. However, this function produces a list of images, not exactly an animation. Thus, we started to work with the big-bang function. As its name suggests, big-bang function creates something, in this case an animation. Even though this new command allows us to create something different and unique, as an animation; I did not like it at first because I had trouble initially understanding what it is asking me to do. Specifically, I was confused on the use of freeze which is a function that basically delete all the previous information of the element, in this case animation. What happens is that you delete all the previous information of an animation. In other words, you cannot come back to the original image. I understood that after performing by myself di...

CSC WEEK 11

Number representation was the topic for week eleven, which basically focused on binary numbers. At the beginning of the week, I did not feel comfortable with binary digits, but through the week I, certainly, progressed with my understanding. As humans, when counting we tend to group things in 10. However, computers do not use decimal numbers, they use voltages, which is similar as use just two fingers, instead of ten. In binary numbers, the only digits are one and zero, and because we are so used to do operations in base ten numbers, it is difficult doing operations with binaries. In fact, it took me a while to feel comfortable doing sum or multiplication with binary, specifically addition. But thanks to the practice fields that professor submitted, I mastered operations with binaries. I realized that it was the same as doing operation with decimal numbers, but just using zero and one, for instance, 1+0=1, 0+1=1. The only difference is when adding one and one, which equals one and ...

FINAL REFLECTION

CSC104 course was a surprisingly interesting course for the different topics studied in class, especially big-bang and Fibonacci numbers. However, sometimes it could be overwhelming when some definition produces an error. That is why I would recommend to a future student when writing a design function do not panic if it does not work at the beginning. Moreover, if you see that is not working properly, go to the interactions area and play with the various parts of your definition to gain a sense of what is the function of each part. Similarly, using check expects will help you at designing your function, because you will see what it is the supposed outcome of the function. Finally, I would strongly recommend using the help manual during the designing of the function, to see which command could help you with the desired output. Basically, for preparing for this course, organization and constant practice are keys. I would say that doing the weekly exercise will help you to master eac...
